[Industrial applications]

 The present invention relates to a mode setting device for a camera that can operate in a normal shooting mode and a function setting mode that sets data for each setting item of camera functions.

[0002]

[Prior art]

 In recent years, various functions have been installed in cameras, for example, special functions such as changing ISO sensitivity and turning on an electronic buzzer when focusing. Conventionally, in setting such a function, a dedicated operation button or the like is provided for each function, and the function is set or changed by the operation button as necessary. However, in the conventional configuration in which a dedicated operation button is provided, it is necessary to increase the number of operation buttons as the number of functions increases, and the number is limited. Furthermore, since the number of buttons increases, the cost increases, and the operability of the camera deteriorates, leading to an increase in erroneous operations.

In addition, by providing a mode changeover switch or the like, the operation mode of the camera is switched from a normal photographing mode to a mode for function setting, and a plurality of setting items and data for each item are selected and set to select a plurality of Some are configured to perform feature settings. In such a mode changeover switch, in order to avoid erroneous operation, the mode is generally switched after the switch is operated for a predetermined time. As described above, when the mode is switched when the operation is performed for a predetermined time, the operator cannot understand the time from operating the switch until the mode is switched, and the mode is switched. The switch operation may be interrupted before, or the switch operation may be continued even though the mode has been switched, and a means for displaying information regarding the passage of time has been desired.

[0004]

In view of the above circumstances, the present invention displays information about the remaining time in a camera that switches the operating state between a shooting mode and a predetermined mode by operating a switch for a predetermined time. It is intended to provide such a display device.

[0005]

[Means for Solving the Problems]

 To achieve the above object, a display device for a camera of the present invention is a camera capable of operating in at least two different modes, a first mode and a second mode, in which an operating member and the operating member are continuously operated for a predetermined time.

[Description of Control System of AF Single-lens Reflex Camera] With reference to FIG. It will be used for photography as a single-lens reflex camera. The configuration of the control system in the AF single-lens reflex camera will be described below with reference to FIG.

That is, most of the subject light flux that has entered the camera body 10 from the zoom optical system of the taking lens 12 is directed toward the penta mirror (not shown) that constitutes the finder optical system by the main mirror 92. After being reflected, a part of the reflected light is incident on the light receiving element 94 (shown in FIG. 11) of the photometric IC. On the other hand, of the subject light flux that has entered the camera body 10, part of the subject light flux that has entered the half mirror portion (not shown) of the main mirror 92 is transmitted through this, and is reflected downward by a sub mirror (not shown) behind it. Not incident on the CCD sensor unit for distance measurement.

The photometric IC described above includes a light receiving element 94 for receiving a subject light flux, and an electric signal generated by the light receiving element 94 in accordance with the amount of received light is logarithmically compressed by the photometric circuit 96, and A / D conversion is performed. The conversion circuit 98 performs A / D conversion, and outputs it to the body side CPU 20 as a photometric signal. The CPU 20 on the body side executes a predetermined calculation based on the photometric signal and the film sensitivity information to calculate an appropriate shutter speed and aperture value for exposure. Then, based on the shutter speed and the aperture value, the exposure control device 100 and the aperture mechanism (not shown) are driven.

The CPU 20 on the body side executes a predetermined exposure calculation based on the digital photometric signal and the film sensitivity information to calculate an appropriate shutter speed and aperture value for exposure. Then, based on these shutter speed and aperture value, the exposure control device 100 and an aperture mechanism (not shown) are driven to perform exposure. Further, at the time of release, the body side CPU 20 drives a mirror motor (not shown) via a motor drive circuit (not shown) to perform up / down processing of the main mirror 92, and after the exposure is finished, a hoisting motor (not shown). To wind the film.

Further, the body side CPU 20 connects the lens side CPU 22 to the connection terminal group 18 provided on the lens mount section 14 and a connection terminal group (not shown) provided on the mount surface of the taking lens 12 via the connection. Communicates data, commands, etc. with and. The photographing lens 12 is provided with a focal length detection mechanism 102 for detecting the currently set focal length, and the focal length detection mechanism 102 is connected to the lens side CPU 22.

In addition, the body side CPU 20 controls the overall control, ROM that stores a program, a control unit 20a that includes a RAM that stores predetermined data, AF (auto focus) calculation, PZ (power zoom) calculation. An arithmetic unit 20b for executing arithmetic processing such as AE calculation and learning operation, and a timer counter 20c are provided, and the control unit 20a is connected to the EEPROM 106 as an external memory means via the controller 104. In addition to various constants specific to the camera body 10, the EEPROM 106 stores various functions and constants necessary for calculation processing such as AF (autofocus) calculation, PZ (power zoom) calculation, AE calculation, and learning calculation. Has been done. Further, an electronic buzzer 108 for oscillating a focusing sound is connected to the controller 104. The electronic buzzer 108 is composed of PCV in this embodiment.

Further, the body side CPU 20 is turned on / off according to the sliding movement of the photometric switch 70 which is turned on by half-pressing the shutter button, the release switch 72 which is turned on by fully pressing the shutter button, and the sliding movement of the main button 30. A main switch 110, a clear switch 76, an up switch 78, a down switch 80, a drive switch 82, a mode switch 84, a hyper switch 88, a cartridge detection switch 90, etc. are connected.

Here, the main switch 110 described above is composed of an on switch 110a and a PICT switch 110b. The on switch 110a is turned on by sliding the main button 36 to the on position, and turned off at other positions. In addition, the PICT switch 110b is configured to be turned on when the main button 36 is slid to the PICT position and turned off at other positions. The main switch 110 is turned on when the on switch 110a or the PICT switch 110b is turned on, and is turned off when both of them are turned off.

Next, the control of the camera of this embodiment will be described based on the flowchart. The main routine includes a POFF loop corresponding to the standby state and a PON loop in the operating state. That is, each process for controlling the camera of this embodiment is executed from the PON loop. The control process is roughly divided into the following four processes. First, a release process for controlling shooting by fully pressing the shutter button 26, and then a display process associated with operation of the mode button 40, drive button 38, Tv / Av button 30, up / down lever 28, hyper button 52, etc. There are a SW operation display loop to be executed, an AE calculation process for controlling various program calculations, and a learning calculation process for controlling a learning function for learning the operation of the photographer. The SW operation display loop is further divided into two processes, one in the exposure mode such as exposure compensation and program shift, and the other in the special function setting mode.

[Main Routine] FIG. 12 is a flowchart showing a main routine of control of the camera of this embodiment. The flow chart starts when the battery is installed in the camera. When the battery is loaded into the camera body 10, first, interrupt processing is prohibited, and initialization processing such as flag initialization, RAM / register initialization, and ROM sum check is executed (S1201, S1203). Next, once in the power hold on state, power is supplied to the hardware of the entire camera, and the data stored in the EEP ROM 106 is written in the RAM of the CPU 20 (S1205, S1207). When the above process is completed, the process proceeds to the POFF loop, which is repeatedly executed when the main switch of the camera is off.

[EEPROM / RAM Data Format] FIGS. 58 and 59 are diagrams showing the formats of the data stored in the EEPROM and the data written in the RAM. The camera of this embodiment has a function of learning the shift amount of the program in each exposure mode of portrait, landscape, moving body, and proximity. Therefore, in each exposure mode, release is performed with GENPSFT (0) to GENPSFT (3) indicating the shift amount of the learning origin in the learned program diagram from the initial origin and the program shift amount set by the photographer. STDYCNT (0) to STDYCNT (3) indicating the number of times of writing are once written in the RAM and further written in the EEPROM 106 as necessary. The data written in the EEPROM 106 is written in the RAM in steps such as S1303 in FIG. 13A and S1207 in FIG. Further, data is transferred from GENPSFT (0) to (3) and STDYCNT (0) to (3) written in the RAM to GENPSFT and ST DYCNT according to the selected exposure mode. Although not written in the EEPROM, in addition to the above GENPSFT and STDY CNT, SETPSFT that stores the program shift amount from the learning origin set by the photographer, and ALLLP that stores the final program shift amount. The SFT is provided on the RAM. FIG. 59 shows the data structure of the data ALLPSFT, SETPSFT, GENEP SFT, and STDYCNT on the RAM described above. As shown in the figure, in ALLPSFT, SETPSFT, and GENPSFT, the 0th bit to the 6th bit represent the absolute value of the shift amount in 1/8 unit, and the 7th bit represents the shift direction. It is the direction bit to represent. Further, S TDYCNT expresses the number of times by the 0th bit to the 5th bit, and the 6th and 7th bits are data relating to the learning situation.

“POFF Loop” In the POFF loop, first, the SW operation display loop is called. In the SW operation display loop, the release switch 72, the photometric switch 70, the main switch 110, the clear switch 76, the up switch 78, the down switch 80, the drive switch 82, the mode switch 84, and the hyper switch 88 are turned on / off. "1" or "0" is set according to the state. Each flag of release SW, photometry SW, main SW, clear SW, UPSW, DOWNSW, drive SW, mode SW, HYPSW, and switch operation. Various flags set according to the above are input to the CPU, and based on this, the display of the external display LCD panel 36 and the internal display LCD panel 62 is controlled (S1211, S1213). Here, when "0" is set in the main SW (that is, when the main button 36 is in the OFF position), only the SW operation display loop is called at a cycle of 128 ms (S1211, S1213), The power hold OFF state is maintained (S1229, S1231, S1233). Even if "1" is set in the main SW (that is, the main button 36 is in the PICT position or the ON position), (1) release switch, (2) photometric switch, (3) hyper switch If (HYPSW), (4) up switch (UPSW), and (5) down switch (DOWNSW) are all "0", or if the PF mode flag is set to "0", While the power hold OFF state is maintained, only the SW operation display loop is called at a period of 128 ms (S1217 to S1233, S1211, S1213). Here, the PF mode flag is set to "1" when the camera is operated in the special function setting mode (PF mode) described later. Therefore, in the PF mode, the process proceeds to RESTART regardless of the state of the operation SW. If any of the above (1) to (5) is turned on during the execution of the POFF loop, the RESTART processing of FIG. 13 is executed.

“RESTART” FIGS. 13A and 13B are flowcharts showing the RESTART process. The RESTART processing is performed in the POFF loop shown in FIG. 12 when "1" is set in the main SW and "1" is set in any of the above flags (1) to (5), or This process is executed when "1" is set in the PF mode flag. In step S1301, power hold is turned on, power is supplied to the entire hardware of the camera, the data in the EEPROM is read again, and the data is written in RAM (S1303). In S1305, the number of repetitions of the PON loop executed thereafter is set in the counter PON timer, and the process proceeds to the PON loop.

“PON Loop” In the PON loop, communication between the camera body 10, the lens 12, and an external flash (not shown), photometric processing, and AE calculation for calculating the Tv / Av value based on the photometric result are performed. Run. It also controls the release process. First, in order to determine the repetition period of the PON loop, the 128 ms timer is started (S1311), and the display of the external display LCD panel 36 and the viewfinder display LCD panel 62 is controlled by the SW operation display loop (S1313). If "1" is set in the main SW (S1315: main SW = "1"), data communication from the external flash to the camera body and communication between the camera body and the lens are performed (S1317, S1319). . Next, normal photometry processing is performed (S1321), and AE calculation is performed based on the photometry data (S1323). After the predetermined data is transmitted from the camera body to the flash based on the result of the AE calculation (S1325), the display process including the calculation result is performed by the SW operation display loop (S1327). When the shutter button 26 is fully pressed (S1329: release SW = “0”), the release process is executed. When the release switch 72 is in the OFF state (S1329: Release SW = "1"), the AF loop is called, and the AF loop is repeatedly monitored while monitoring the release SW state until the 128 ms timer expires. Is called (S1329 to S1333). After 128 ms has elapsed, all of the photometry SW, HYPSW, UPSW, and DOWNSW are in the OFF state (the state where “0” is set), and the PF mode flag = “0” (indicating that the special function setting mode is not set). When the PON loop is repeated the number of times set in S1305 while being held (S1335-S1343), the process shifts to the POFF loop (S1345-S1347). On the other hand, in cases other than the above, the PON loop is repeated.

“Release Processing” FIG. 14 is a flowchart illustrating the release processing. In the release processing, photometric processing (S1401), data communication from the flash to the camera body (S1403), AE calculation (S1405) described later, data communication from the camera body to the flash based on the AE calculation result (S1407), SW operation After the display loop (S1409) is performed, a series of exposure operations of mirror up, aperture control (S1411), exposure processing (S1413), film winding and mirror down (S1417) are executed. In the camera of the present embodiment, after the exposure process is completed, a learning operation described later is executed (S1415) to learn the setting of the photographer. When the release process is completed, the process again moves to the PON loop shown in FIG.

[Switch Operation Display Loop] FIG. 15 illustrates a SW operation display loop that controls the display of the external display LCD panel 34 and the in-viewfinder display LCD panel 62 in accordance with the operation of the operation buttons of the camera. It is a flowchart to do. In the SW operation display loop, processing according to the operation of the operation button such as ISO sensitivity display and switching between the PF setting mode and other shooting modes is performed and displayed. In S1501, as shown in FIG. 11, the state of each switch set according to the operation of the operation button of the camera is read, and each flag (main SW, PF mode flag, mode SW, drive SW, PFOUTM flag) is read. Set.

In the camera of the present embodiment, when the mode button 40 and the drive button 38 are simultaneously pressed in the normal photographing enabled state, the ISO sensitivity is first displayed on the external display LCD panel 34, and when the simultaneous pressing is continued for a predetermined time. , PF setting mode (special function setting mode) is entered. When the PF setting mode is entered, "1" is set in the PF mode flag (described later). In the SW operation display loop, if the main SW is "0", the external display LCD panel 34 and the in-finder display panel 62 are turned off, and after the PF cancel processing described later is performed, the SW operation is performed. Return to where the display loop was called.

When “1” is set in the main SW and the PF setting mode is not entered, the states of the mode SW and the drive SW are determined. When "0" is set in both the mode SW and the drive SW, the process branches depending on the PFOUTM flag. The PFOUTM flag is set to "1" only when the PF setting mode is normally terminated after the PF setting mode is once entered, and is normally "0". Even when the normal exposure mode is returned from the PF setting mode, the mode button 40 and the drive button 38 are simultaneously pressed and held for a predetermined time. When both the mode SW and the drive SW are “0”, the PF timer is incremented from 0. When the PF timer is less than 31, the ISO sensitivity is displayed on the external display LCD panel, and at the same time, the remaining time until the PF mode is entered by the PF timer display processing is displayed in a graph (described later). When the PF timer display processing is completed, it returns to the place where the SW operation display loop was called. In S1513, when the PF timer becomes 31 or more, the PF mode flag indicating that the PF mode is entered is set to 1, and the PFINM flag is also set to "1". The PF timer = 31 corresponds to a time interval of approximately 2 seconds. If "1" is set in the PF mode flag, the process proceeds from S1505 to the PF loop when the SW operation display loop is called next time. The PF loop monitors the state of each switch while operating in the PF setting mode. The PF loop will be described later. In the present embodiment, the ISO is displayed only while the mode button 40 and the drive button 38 are simultaneously pressed. It may be controlled so as to display ISO.・

If either the mode SW or the drive SW is turned off during the ISO sensitivity display, that is, while the remaining time until entering the PF mode is displayed as a graph, the PF timer is cleared and 0 is set. Further, "0" is set in the PFOUTM flag. If the drive button 38 and the mode button 40 are kept being pressed when the PF setting mode is changed to the exposure mode, the PFOUTM flag is set to "1". The process is advanced to, so that the P F setting mode will not be entered again. To move to the PF setting mode again, release either the mode button 40 or the drive button 38 once, set the PFOUTM flag to "0" in S1525, and then press both buttons again at the same time. It is possible to shift to the setting mode. In this way, immediately after switching from the PF setting mode to the shooting mode, even if the drive button and the mode button are kept pressed, the PF setting mode is not switched again, and the operability is improved. During operation in the normal exposure mode, if at least one of the mode button and the drive button is not pressed, the process related to the PF setting mode is not performed, and the process proceeds to the process of the SW operation display 1 (S1507, S1509, S1525). ).

“Switch Operation Display 1” FIGS. 16A, 16 B, and 16 C are flowcharts of the SW operation display 1. In the SW operation display 1 process, the display of data selected and set by operating the up / down lever 28 is controlled. First, in S1601, the learning mode flag is set to 0. In this embodiment, the learning prohibition flag is set to “0” (learning permission) in the PF setting mode, and the learning mode flag is set to “1” only in the learning mode (person, landscape, moving body, proximity). "Is set and learning is performed (described later). In the U / D loop executed in S1603, various setting / display processing is performed according to the operation of the up / down lever 28 (details will be described later). In the AE mode setting process of S1605, depending on the data set in the U / D loop and whether the main button 36 is in the PICT position or the ON position, the exposure mode is green, person, landscape, moving body, proximity, program.・ Which mode is auto or manual is determined (details will be described later), and the variable “AE mode” is set to a value according to the exposure mode.

Next, the process branches depending on the exposure mode (S1608 to S1609). In FIG. 16B, S1611 to S1621 are processes related to program shift, which will be described later, and S1623 and S1625 are processes related to exposure correction. When the exposure mode is the green mode or the manual mode, the above steps are not performed because the program shift and the exposure correction are not performed. In the auto mode, only the exposure compensation is performed and the program shift is not performed. Further, in the program mode, although the graph is not displayed, the program shift is possible and the processing from S1619 is performed.

When the exposure mode is the person / landscape / moving body / proximity mode, the camera of this embodiment has a function of learning the program shift amount set by the photographer. This learning function is valid only when a camera is attached to the camera and the learning prohibition flag is set to "0" in the PF setting mode. When the above conditions are satisfied, the learning mode flag is set to "1" (S1611-S1615). Next, in the P shift graph display process, the program shift amount set by the photographer is displayed as a graph on the external display LCD panel 34 and the in-finder display LCD panel 62. The set program shift amount can be canceled by pressing the Tv / Av button 30 independently. In step S1619, program shift cancel processing is performed (details will be described later). In S1621, the process of displaying the characters “Tv” and “Av” and the arc-shaped overlines 58k and 58m on the external display LCD panel 34 is performed.

As described above, in the camera of this embodiment, when the exposure mode is person / landscape / moving body / proximity / program / auto, exposure correction can be set. When the hyper button 52 is pressed, a graph of exposure compensation is displayed on the external display LCD panel 34 and the viewfinder display LCD panel 62. With the exposure compensation graph displayed, that is, by rotating the up / down lever 28 while pressing the hyper button 52, the compensation amount is set (S1623). The set exposure compensation amount can be cleared by pressing the Tv / Av button 30 while the exposure compensation graph is displayed (S1625). Details of the exposure compensation display and exposure compensation clear processing will be described later.

When the exposure mode is auto, the shutter priority or the aperture priority can be switched by operating the Tv / Av button 30 (S1627). In the case of shutter priority, the Tv value can be changed by operating the up / down lever 28. In the case of the aperture priority, the Av value can be changed by operating the up / down lever 28. At this time, on the external display LCD panel 34, the arc-shaped overline 58k or 58m is displayed on the priority side of Tv or Av, and on the internal display panel, the priority Tv value or Av is displayed. The value is underlined (S1629).

When the exposure mode is manual, the deviation of the manually set Tv / Av value from the calculated proper exposure value is graphically displayed by the exposure display process (S1631). In the manual mode, when the hyper button 52 is pressed alone, the proper exposure value calculated according to the program is set. The Tv / Av value is set in the manual mode with the up / down lever 28. Which is set by the up / down lever 28 is switched by the Tv / Av switch 30 as in the case of the auto mode (S1633). Further, as in the case of the auto mode, an arc-shaped overline 58k or 58m is displayed on the external display LCD panel 34, whichever of Tv or Av can be changed by the up / down lever 28. Then, the underline is lit on the Tv value or the Av value on the in-viewfinder display LCD panel (S1635). The Tv value and Av value determined as described above are displayed on the external display LCD panel 34 and the in-finder display LCD panel 62 (S1637), and the display of each exposure mode / drive mode and the presence / absence of learning are displayed. The display and other various displays determined for each mode are performed (S1641).

“PF Loop” FIG. 17 is a flowchart of the PF loop process. In the PF loop process, the process branches to the PF loop 1 process that sets and changes various special functions in the PF setting mode, and controls the process to return to the normal exposure mode after the function setting is completed.

For the setting of the special function (PF), in the PF setting mode, the setting item is selected by operating the mode button 40, and the data is changed by rotating the up / down button 28. During the PF setting mode operation, if one minute elapses without performing the above special function setting operation, the PF setting mode process is canceled and the exposure mode is restored. Therefore, when any of the mode SW, UPS W, and DOWNSW is turned on by the PF end timer, the PF end timer is set to 0, and when none of the modes is turned on, the timekeeping is continued. When the mode button 40 and the drive button 38 are pressed simultaneously from the normal exposure mode to proceed to the PF loop, since the PFINM flag is set to "1" in S1527 of FIG. 15, the PF display is started from S1715 of FIG. Proceed to processing. Since the PFINM flag is set to "0" in this PF display process, the PF display process is executed only when the process proceeds to the PF setting process, and once the mode button 40 or the drive button 38 is released, PF It is not executed during the setting mode operation.

As described above, the setting items are changed by the PF loop 1 when the mode SW is ON (that is, when the mode switch is set to “0”). When the state in which both the mode SW and the drive SW are set to "0" continues for a predetermined time (2 seconds in this embodiment), the process proceeds to the PF setting end process, and the set special function is confirmed (written in the EEPROM 106). The counting and display of the time until the PF setting end process is performed are the same as in S1513, S1515, and S1519 of FIG. 15 (S1717, S1719, S1721).

“PF Display Processing” FIG. 18 is a flowchart showing the PF display processing that is executed when the normal exposure mode is advanced to the PF setting mode. The PF display process is executed when the mode button 40 and the drive button 38 are pressed at the same time in the normal exposure mode operation state, the ISO sensitivity display is performed, and a predetermined time elapses before the mode is changed to the PF setting mode. It

In FIG. 15, when the count value of the PF timer becomes equal to or greater than the predetermined value (31) (immediately when the mode button 40 and the drive button 38 are continuously pressed for 2 seconds), in S1527, the PF mode flag and the PFINM flag are set. Is set to "1". Then, when the SW operation display loop of FIG. 15 is executed next while the mode button 40 and the drive button 38 are still pressed, the processing proceeds to the PF loop in S1505, and further, the PF loop of FIG. The process proceeds from the loop S1715 to the PF display process of FIG.

In the PF display process, first, [PF] is displayed to indicate that the mode has been changed to the PF setting mode, and "1" is set to the mode SWM flag described later. At this point, if the Tv / Av button 30 has not been pressed (S1803: clear SW = “1”), the process returns to the place where the SW operation display loop branched to the PF display process is called.

In the camera of this embodiment, when the Tv / Av button 30 is pressed when the mode button 40 and the drive button 38 are pressed and [PF] is displayed on the external display LCD panel 34, the special setting All functions are cleared and set to default values. S1805 to S1815 are processes for that purpose. When the Tv / Av button 30 is pressed (S1803: clear SW = “0”), “0” is set in the mode SWM flag. In order to set the PF timer to 0 only when the processing after S1805 is first performed, the processing is branched by the PFINM2 flag in S1807. That is, since PFINM2 = "0" only for the first time and PFINM2 = "1" for the second time and thereafter, the PF timer is not reset. The processing of S1811-S1815 is the same processing as S1515-S1519 of FIG. 15 or S1717-S1721 of FIG. When a predetermined time elapses, that is, when the count value of the PF timer exceeds 31, the process proceeds to the PF all clear process, and the set value is returned to the default value.

“PF Loop 1” FIGS. 19A and 19B are flowcharts showing the process of the PF loop 1, which controls the setting of the special function and the display of the setting contents. In the camera of the present embodiment, if the setting operation is not performed for one minute or more while operating in the PF setting mode, all the setting contents during the operation in the PF setting mode are canceled and the mode shifts to the PF setting mode. The setting contents just before the setting is retained as they are. Therefore, first, in S1901, it is determined whether the PF end timer is 1 minute or longer. As shown in S1701 to S1707 of FIG. 17, the PF end timer is reset each time it is determined that one of the modes SW, UPSW, and DOWNSW for performing PF setting is in the ON state. That is, each time the mode button 40 or the up / down lever 28 is operated, the PF end timer is set to 0. Therefore, if neither the mode button 40 nor the up / down lever 28 is operated for 1 minute or more, the process proceeds from S1901 to the PF cancel process.

On the other hand, during the operation in the PF setting mode, the process proceeds from S1901 to S1903. First, in S1903, "0" is set in the PFINM flag and the count value 0 is set in the PF timer. The PFINM flag is set to 1 in S1527 of FIG. 15 when shifting from the exposure mode to the PF setting mode, and controls the branch to the PF display process in S1715 of FIG. If the mode button 40 and the drive button 38 are still pressed after the shift to the PF setting mode, the PFINM flag = “1”, and therefore the process always proceeds from S1715 to the PF display process. Further, once the mode button 40 or the drive button 38 is released, the PF display processing is no longer performed, the processing proceeds from S1715 to S1717, and the PF setting end processing can be executed.

In order to shift from the PF setting mode to the exposure mode, the mode button 40 and the drive button 38 must be simultaneously pressed for a predetermined time. The PF timer counts this time, and as can be seen from S1711, S1713 in FIG. 17, once the mode button 40 or the drive button 38 is released, the PF timer is set to 0. Become. Next, in S1905 and S1907, it is determined whether or not the up / down lever 28 has been operated. When the up / down lever 28 is operated to the up side, the UPM flag is set to "1" in the U / D loop described later. When it is operated to the down side, the DOWNNM flag is set to "1".

When the up / down lever 28 is not operated, the setting item of the special function is changed by operating the mode button 40 in S1909. In the camera of the present embodiment, as special functions whose settings can be changed, (A) ISO sensitivity, (B) learning change level, (C) presence or absence of AF focusing sound, (D) presence or absence of learning, and (E) learning There are 5 items, Clear. These five items are sequentially selected (A), (B), (C), (D), (E) each time the mode button 40 is pressed in the PF setting mode, and further (E) is selected. When the mode button 40 is pressed again in the state of being present, (A) is selected.

Next, in S1911, the U / D loop is executed only when the mode SWM flag is 0. In the U / D loop, the operation of the up / down lever 28 changes the data in the setting item. In the camera of this embodiment, the setting item or the data is changed only when only one of the mode button 40 and the up / down lever 28 is operated. For this reason, it is determined from the mode SWM flag whether or not to call the U / D loop in S1913. The mode SWM flag is changed in the PF mode UP processing of S1909 (details will be described later). In S1915 to S1927, the set item and its data are displayed. When the setting item is (A), the ISO speed of the film is displayed. When the setting item is (B), numerical values 0 to 4 corresponding to the selected combination of the learning level and the number of times are displayed. When the setting item is (C) above, in addition to the display of "0" (the electronic buzzer 108 is sounded at the time of focusing) or "1" (the electronic buzzer 108 is not sounded at the time of focusing), "0" is displayed. When "" is selected, the buzzer sounds periodically, and when "1" is selected, the buzzer does not sound so that the settings can be confirmed auditorily. . In the case of setting item (D), in addition to the numerical display of "0" (learning) and "1" (not learning), the setting contents can be easily checked visually by turning on / off the learning mark. It is becoming like this. In the case of the setting item (E), a picture indicating the selected exposure mode and the character "CL" indicating that clear is set are displayed. The PF loop 1 is a branch from the SW display operation processing loop, and when the above processing is completed, it returns to the place where the SW display operation processing loop was called.

“PF Mode UP” FIG. 19C is a flowchart showing the PF mode UP processing called in S1909 of FIG. 19A. This process is called when the up / down lever 28 is not operated. When the PF mode UP processing is executed, it is first determined whether or not the mode button 40 has been operated (S1931). When the mode SW is set to "1", the mode SWM flag is set to "0". As a result, the processing advances from S1911 to S1913 in FIG. 19A, and the data can be changed by the up / down lever 28.

When the mode SW is set to "0", the PF mode is incremented (S1937) only when the mode SWM flag is set to "0", and the setting item is changed. Since there are five types of PF modes 0 to 4, 0 is set when the PF mode is 5 or more (S1939). Once the PF mode is incremented, the mode SWM flag is set to "1" (S1943). In this manner, after the mode button 40 is pressed to change the setting item and the mode button 40 is still being pressed, the processing of changing the setting item in S1935 is not executed. That is, the control is such that the setting items do not change unless the mode button 40 is once released, and the operability is very good. When the process is completed, the process returns to the place where the PF mode UP process was called.

[PF All Clear / PF Setting End Processing] FIG. 20 is a flowchart showing the PF all clear processing and the PF setting end processing. The PF all clear processing is executed when the count value of the PF timer becomes 31 or more in S1811, in the PF display processing of FIG. That is, the mode button 40 and the drive button 38 are simultaneously pressed for a predetermined time to enter the PF setting mode, and while the [PF] is displayed on the external display LCD panel 34, the Tv / Av button 30 is further set. It is executed by pressing and holding for a time (2 seconds). In the PF all clear processing, all the data whose settings can be changed in the PF setting mode are returned to the initial values (S2001).

With respect to the ISO sensitivity setting, if the camera is loaded with DX film, the ISO sensitivity read from the DX code of the film is set as an initial value, and in other cases, the ISO sensitivity is set to 100 as a default value. Is set. As for the learning change level, the change level = 0, the number of times 1 = 3, and the number of times 2 = 3 are set as initial values. With respect to the focusing sound, the electronic buzzer 108 is set to sound at the initial setting, and the learning is set at the initial setting regarding the presence or absence of learning. Regarding the learning clear flag, in order to clear the learning for each of the four exposure modes of person, landscape, moving body, and proximity, "1" is set to all the learning clear flags corresponding to each mode.

The above setting is performed on the RAM, and then the data on the RAM is written to the EEPROM 106 in the PF setting end processing after S2011. Regarding the ISO sensitivity, learning change level, presence / absence of focusing sound, and presence / absence of learning, which are irrelevant to the exposure mode, the data in the RAM set / changed in the PF setting mode corresponds to the data in the EEPROM as they are. . Therefore, the data in the RAM is directly written in the EEPROM (S2011). On the other hand, learning clear only changes the value of the learning clear flag for each mode, so only when the value of the learning clear flag (X) corresponding to each mode is 1, the GENPSFT (X) and STDYC The contents of NT (X) are rewritten and further written in the EEPROM (S2013 to S2019). When the above processing is completed, the processing proceeds to S2111 in FIG. 21, and various flags and counters are reset. Here, "1" is set to the flag PFOUTM flag indicating the shift from the PF setting mode to the exposure mode. The PF all clear processing is a branch from the SW operation display loop. Therefore, when this PF all clear process is completed, the process returns to the place where the SW operation display loop was called.

“PF Canceling Process” FIG. 21 is a flowchart illustrating the PF canceling process. In the camera of this embodiment, the special function is set in the PF setting mode, and the set contents are written in the EEPROM by continuously pressing the mode button 40 and the drive button 38 for a predetermined time (see FIG. 17 and FIG. 17). (See FIG. 20), the PF setting mode ends. However, if the PF setting mode is interrupted by any other method (that is, if the main button 36 is set to the OFF position during operation in the PF setting mode, or if the setting operation is not performed for 1 minute or more in the PF setting mode). In this case, the contents changed in the P F setting mode are not written in the EEPROM 108 but canceled. In particular, if the setting operation is not performed for 1 minute or more in the PF setting mode, the PF setting mode is automatically shifted to the exposure mode, and the data stored in the EEPROM 108 is written in the RAM. When the cancel process is executed, the learning clear flag (X) of each mode is set to "0" so that the learning is not cleared in any mode (S2101). The PF cancel processing is branched from the SW operation display loop. Therefore, when this PF cancel processing is completed, it returns to the place where the SW operation display loop is called.

[U / D Loop Processing] FIG. 22 is a flowchart showing a U / D loop for changing data by operating the up / down lever 28. When the down switch 80 is turned on (when DOWNSW is set to "1"), the DOWNM flag (DOWN memory flag) is set to "1" and the UPM (memory) flag is set to "0". To be done. On the other hand, when UPSW is set to "1", the UP memory flag is set to "1" and the DOWN memory flag is set to "0" (details will be described later). Therefore, when the up switch 78 is on, the UP loop flag is set to "1", the UP loop processing is performed, and the DOWN loop processing is not performed (S2201 to S2205). On the other hand, if the down switch 80 is on, the UP loop flag is set to "0" and only the DOWN loop processing is performed (S2207 to S2211). When the above process is completed, the process returns to the place where the U / D loop is called.

“UP Loop” FIG. 23 is a flow chart showing the processing of the UP loop called in the U / D loop (FIG. 22). When the up switch 78 is off (S2301: UPSW = “1”), the data is not changed and “0” is set to the UP memory flag indicating that the up switch 78 is off. (S2303), the process returns to the U / D loop. If the up switch 78 is on (S2301: UPSW = “0”), it is determined whether the up switch 78 was on when the UP loop was called last time (S2305), and if it was also determined to be on last time (S2305). When the UP memory flag = “1”), the process proceeds to the U / D timer loop. The U / D loop is repeated at a cycle of approximately 64 ms (twice every 128 ms). Therefore, if data is changed only by the state of the up switch 78 at the time when the UP loop is called, for example, the up switch is performed. If 78 holds the ON state, that is, if the operator holds the state while operating the up / down lever 28 in the up direction, the data is changed in a very single time. Will end up. In order to prevent this, when the up switch 78 or the down switch 80 is continuously turned on, the U / D timer loop softly extends the cycle. When the UP memory flag is “0”, the data is changed by the data U / D process, and the UP memory flag indicating that the up switch 78 is on is set to 1, and the down switch 80 is turned off at the same time. "0" is set to the DOWN memory flag indicating that, and the count value of the U / D timer used in the U / D timer loop is set to 0 (S2305 to S2309).

[DOWN Loop Processing] FIG. 24 is a flowchart showing a DOWN loop. In S2401 to S2409, almost the same processing as in FIG. 23 is performed according to the on / off state of the down switch 80.

“U / D Timer Loop Processing” S2411-S2417 represent the processing of the U / D timer loop. In the U / D timer loop, each time this processing is executed (S2417), when the count value of the U / D timer becomes 8 or more (S2411), the data of the special function is changed (S2413). That is, when this process is executed eight times while the up / down lever 28 is operated, the data is changed according to the operating direction of the up / down lever 28. When the data is changed, the U / D timer is reset and the count value is set to 0 (S2415).

[Data U / D Processing] FIG. 25 is a flowchart of data U / D processing for executing data change in response to operation of the up / down lever 28. If the operation is in the PF setting mode (S1501: PF mode flag = “1”), the process branches to the PF data U / D process, and the special function is changed by the combination of the up / down lever 28 and the mode button 40. -The setting is executed. When the PF mode flag = “0”, the process is branched by the operation button which is pressed in combination with the up / down lever 28. When operating the up / down lever 28 while pressing the mode button 40, the exposure mode is changed (S2503, S2505). When operating the up / down lever 28 while pressing the drive button 38, the photographing mode is changed (S2507, S2509). When the up / down lever 28 is operated while pressing the hyper button 52, exposure correction is performed (S2511, S2513). When only the up / down button 28 is operated, (1) if the shooting mode is one of portrait, landscape, moving body, proximity, and program, program shift is executed (S2517, S2519), (2) If the shooting mode is auto or manual, the Tv value or Av value is changed (S2521, S2523, S2524). Which of the Av value and the Tv value is set can be switched by operating the Tv / Av button 30. After the above processing is performed, it returns to the place where the data U / D processing was called.

[PF Data U / D Processing] FIG. 26 is a flowchart of the PF data U / D processing for changing the data of each item of the PF (special function) in the PF setting mode. The data of the item of the special function set by the operation of the mode button 40 in S1909 of FIG. 19 is changed (S2601, S2603). When the setting item is the ISO sensitivity change, the ISO sensitivity is changed stepwise by operating the up / down lever 28 (S2605). If you press the Tv / Av button 30 while setting the ISO speed, the initial value as the ISO speed (the DX value by the DX code when DX film is loaded in the camera, otherwise the default value = 100) is set. When the setting item is the learning change level, the variable corresponding to the combination of the change level and the number of shutters is set to any of 0 to 4 by operating the up / down lever 28. Here, the first level of change level is about 0. This corresponds to a program shift of 5 Ev, and if the program shift amount actually set by the photographer is equal to or higher than the change level selected here, it is learned that the number of exposures indicated by the number 1 is performed, and If the set program shift amount is less than the selected change level, learning is performed when the number of exposures indicated by the number 2 has been performed (S2607). If the setting item is the presence or absence of AF focusing ON, the focusing ON prohibition flag is toggled between "0" and "1" by operating the up / down lever 28 (S2609). If the setting item is learning prohibition, the learning prohibition flag is toggled between "0" and "1" by operating the up / down lever 28 (S2611). When the setting item learning clear is set, a picture display representing the shooting mode is displayed on the external display LCD panel 34, and one of four modes for clearing learning is operated by operating the up / down lever 28. , Or select all four and press the Tv / Av button 30 to perform clear setting (S2613).

[P-Shift U / D Processing] FIG. 27 is a flowchart of P-shift U / D processing for setting program shift. In the camera of the present embodiment, the program shift is not performed when the exposure mode is the green mode, and therefore the processes after S2703 are not performed (S2701: P shift prohibit flag = “1”). Only when the Tv value does not exceed the maximum value and the Av value does not reach the minimum value when the operation direction of the up / down lever 28 is the forward direction (S2705: TvMAX = “0”, S2707: AvMIN). = “0”), it is possible to shift. When the P shift direction bit stored in the RAM is negative, the P shift amount is decreased by 0.5 until the P shift amount becomes 0. When the P shift amount becomes 0, the direction bit is changed to positive (S2717 to S2721). When the direction bit is positive, 0.5 is added to the P shift amount unless the maximum value of the P shift amount is 15 4/8 or more (S2713, S2 715). When the operating direction of the up / down lever 28 is negative, the Tv value is larger than the minimum value, and the shift is possible only when the Av value does not exceed the maximum value. When the P shift direction bit on the RAM is positive, the P shift amount is decreased by 0.5. However, when the P shift amount becomes negative as a result of this, since the data on the RAM is represented by a binary number, data processing is performed so that the data is represented by the negative direction bit and the absolute value of the shift amount. (S2729 to S2733). When the direction bit is negative, 0.5 is added to the P shift amount unless the P shift amount becomes the maximum value or more (S2735, S2737).

[Exposure Correction U / D Processing] FIG. 28 is a flowchart of the exposure correction U / D processing. Depending on the operating direction of the up / down lever 28, Xv is increased by 0.5 in the positive direction up to the upper limit Xv = 3.0 (S2801 to S2805), and in the negative direction, the lower limit Xv = −3.0. It is decreased by 0.5 (S2801 to S2807).

[P Shift Graph Display Processing] FIG. 29 is a flowchart showing the P shift graph display processing for displaying the set program shift amount in a graph. In the program shift graph display, the data of the P shift display table shown in FIG. 31 is read out and displayed based on the shift direction / amount of the origin and the program shift direction / amount set on the basis of the origin. In addition, in FIG. 31, the black circles represent the lit parts, and the black circles with radial lines drawn around them indicate that the black circles are blinking. The data specified by Y and Z in FIG. 31 is displayed on the external display LCD panel 34 and the viewfinder display LCD panel. In FIG. 29, the direction bit and shift amount of the origin corresponding to the set exposure mode are read from the RAM (S2901 to S2905), and the Y value of FIG. 31 is calculated from the origin direction bit and the origin shift amount ( S2907 to S2911). Next, Z in FIG. 31 is calculated from the P shift direction bit, the P shift amount, and the value of Y (S2913 to S2917). When Z is negative or 11 or more, Z = 0 and Z = 10 are set (S2919 to S2925). Based on Y and Z obtained as described above, the display data of the display table of FIG. 31 is written in the RAM for displaying the LCD (S2927, S2929).

[Exposure Compensation Display Processing] FIG. 30 is a flow chart for explaining the exposure compensation display called in S1623 of FIG. According to the set exposure correction value Xv, "1" is set to any of the Xv zero flag, the Xv plus flag, and the Xv minus flag (S3001 to S3011). When the hyper button 52 is pressed and HYPSW is set to "0", the exposure correction value Xv is displayed numerically (S3013, S3015), and the exposure correction graph display processing of S3031 and thereafter is executed.

When “1” is set in HYPSW, if the exposure correction value is 0, no graph is displayed (S3013, S3017, S3019), and the process proceeds to S1624 of SW operation display 1. When "1" is set in HYPSW and the main button 36 is at the PICT position, a "+" or "-" mark is displayed on the external LCD panel 34 and the viewfinder display LCD depending on whether Xv is positive or negative. It is displayed on the panel 62 (S3021 to S3027). When the hyper SW is OFF and the main button 36 is in the ON position, the process proceeds to the exposure correction graph display (S3021: PICTSW = 1). In the exposure correction graph display, using the data in the exposure correction graph display table shown in FIG. 40, a graph is displayed on the external display LCD panel 34 and the viewfinder display LCD panel 62 according to the correction amount. Data in the display table of FIG. 40 is selected from the exposure correction value Xv, the scale is displayed on the external display LCD panel 34 and the in-finder display panel 62, and the selected data of FIG. 40 is displayed. The exposure correction value that can be displayed in a graph is -2. Although it is in the range of 0 Ev to +2.0, the range of exposure correction values that can be set is -3.0 Ev to +3.0 Ev. Further, when the correction value exceeds the area of the graph display, a black circle mark is blinked at the end point of the graph to indicate that it is outside the area. When the above process is completed, the process of S1624 of the SW operation display 1 is executed.

[PF Timer Display] FIG. 32 shows a PF timer display process for displaying the remaining time when the drive button 38 and the mode button 40 are simultaneously pressed to enter the PF setting mode and when the PF setting mode is exited. 2 is a flowchart showing The switching between the PF setting mode and the exposure mode is switched when the count value of the PF timer becomes a predetermined value (31) or more (FIGS. 15 and 18). Therefore, by selecting the PF timer display data shown in FIG. 37 based on the value of the PF timer and writing it to the display RAM, a graph display corresponding to the remaining time is displayed on the external display LCD panel 34. (S3201, S3203).

[AE Mode U / D Processing] FIG. 34 is a flowchart of the AE mode U / D processing for selecting the exposure mode by the up / down lever 28. In S3401, the processing is divided according to the direction in which the data is changed, that is, according to the operation of the up / down lever 28. In S3403, the exposure mode is divided into the picture mode (PICT mode) or the full spec mode (FULL mode) depending on whether the main button 36 is in the PICT position or the ON position. On the RAM, the exposure mode is set by setting 1 to any one digit of 8-bit data and 0 to the other, as shown in FIG. When the 8-bit data corresponding to the exposure mode is shown as the exposure mode [8-bit data], it is represented in the PICT mode as the green mode [00000001], the moving object mode [00001000], etc., and the FULL mode. Then, it is represented as in the auto mode [00000010]. When the above 8-bit data is represented by a decimal number and expressed as an exposure mode (10 decimal number), it can be represented as a green mode (1), a moving object mode (8), an auto mode (2), and the like. From FIG. 33, for example, in the PICT mode, when the left mode is shifted from the green mode [00000001], the person mode [00000010], the landscape mode [00000100], the moving object mode [00001000], and the proximity mode [00010000] are set in order. In the present embodiment, since there are five exposure modes set in the PICT mode, the maximum value of 8-bit data is [00010000], and in S3405 of FIG. 34, when the value of the PICT mode becomes 16 or more, left shift is performed. Since the exposure mode corresponding to the data no longer exists, it has been reset back to 1. As a result, even if the up / down lever 28 is continuously operated in the direction in which the data changes as described above, the green mode can be selected next to the proximity mode, which greatly improves the operability. ing. The processes of S3415 to S3419 are the same as the above for the FULL mode. The processing of S3421 to S3433 is processing when 8-bit data is right-shifted, and in principle, the same processing as described above is performed.

“AE Mode Setting Process” FIG. 35 shows an AE mode setting process for converting the value of the PICT mode or the FULL mode set in the AE mode U / D process of FIG. 34 into the variable AE mode. It is a forgotten flowchart. In the AE mode U / D processing, the PICT mode is represented by binary numbers [00000001] to [00010000], and the FULL mode is represented by [00000001] to [00000100]. The AE mode setting process is a process for representing the PICT mode and the FULL mode by one type of variable “AE mode”. First, the initial value of the "AE mode" is set by the position of the main button 36 (S3501, S3503, S3507). Next, the value of the PICT mode or the FULL mode set by the AE mode U / D of FIG. 35 is put into the variable N (S3505, S3509). After that, N is shifted to the right until N = 1 and the number of shifts is added to the initial value of the AE mode, so that the relationship between the AE mode and the exposure mode as shown in FIG. 36 is obtained.

“P Shift Clear Processing” FIG. 38 is a flowchart illustrating the P shift clear processing called in S1619 of FIG. By pressing the Tv / Av button 30 independently, the set program shift amount is canceled and the program returns to the origin position. In the camera of the present embodiment, when the Tv / Av button is pressed while the hyper button 52 is being pressed, the exposure correction is cleared, so when the hyper button 52 is not pressed (S3801: HYPSW = "1"). Only ") can clear the program shift.

“Exposure Correction Clearing Process” FIG. 39 is a flowchart illustrating the exposure correction clearing process called in S1625 of FIG. By simultaneously pressing the hyper button 52 and the Tv / Av button, the exposure correction value Xv is set to 0 (S3901 to S3905).

[Position of Main Button and Initial Display Screen] FIGS. 60A to 60C show examples of display screens of the external display LCD 34 and the in-finder display LCD panel 62 when the main button 36 is at the PICT position. FIG. 60A shows a state where the main button 36 is placed in the PICT position. 60B and 60C show the display screen of the in-viewfinder display LCD panel 62 and the display screen of the external display LCD panel 34 at that time. In this example, the portrait mode is selected as the exposure mode.

61A to 61C show an example in which the main button 36 is in the ON position. 61B and 61C show display examples of the external display LCD panel 34 and the viewfinder display LCD panel 62, respectively. As will be described in detail later, in this example, the program mode is selected as the exposure mode, and further, −0. It can be seen that the exposure correction of 5 Ev is set.

Similar to FIG. 60C, FIG. 62 shows a display example of the external display LCD panel 34 when the main button 36 is at the PICT position. In this example, the portrait mode is still selected as the exposure mode. From this display screen, it can be further seen that the learning function is turned on and the program shift of +0.5 Ev has already been learned. In addition, positive exposure compensation is performed. The display of the program shift and the display of the exposure compensation will be described in detail later.

“Display Processing in PF Setting Mode” FIGS. 63A to 63F show the display on the external display LCD panel 34 when shifting to the PF setting mode processing. By the PF timer display processing called in S1519 of FIG. 15, the PF timer display data of FIG. 37 is set in the RAM and displayed (FIGS. 63A to 63E). The ISO sensitivity is displayed in step S1517 of FIG. 15 until the PF setting mode is entered. All other displays are turned off and only the necessary data is displayed. In the case of the camera of this embodiment, the time from the display of nine dots to the disappearance of all nine dots is about 2 seconds. When the predetermined time (about 2 seconds) has elapsed and all the dots have disappeared, the PF display process of FIG. 18 is executed, and [PF] is displayed as shown in FIG. 63F. Here, when the mode button 40 and the drive button 38 are released, the display for changing the ISO sensitivity, which is the first setting item in the PF setting mode, is displayed (see FIG. 65A).

[Display of PF All Clear Processing] When the PF setting mode is entered and the [PF] is displayed and the Tv / Av button 30 is pressed, the PF timer display is called in S1815 of FIG. A dot is displayed (Fig. 64A). Similar to the above processing, when all 9 dots disappear in about 2 seconds, all the PF (special function) settings are cleared (Fig. 20: PF all clear processing), and the external display LCD panel 34 displays CL is displayed as shown in 64B.

[Setting of Special Function and Display Processing] As described above, while operating in the PF setting mode, a setting item is selected by operating the mode button 40 and selected by rotating the up / down lever 28. Change the data in the specified item.

[Setting of ISO Sensitivity] FIGS. 65A and 65B show display screens for changing ISO sensitivity. The data changed in S2605 of the PF data U / D processing of FIG. 26 by the operation of the up / down lever 28 is displayed in S1919 of FIG. 19B. The figure shows an example of the case where the ISO 200 (FIG. 65A) is changed to the ISO 100 (FIG. 65B). Note that [1] indicating the setting item is also displayed at the same time. As described above, when the Tv / Av button 30 is operated during the setting, the ISO sensitivity is set to the initial value (DX value or ISO = 100).

“Setting of Number of Learnings” FIGS. 66A and 66B are displays when setting the number of learnings. A setting item [2] is displayed, and a numerical value from 0 to 4 indicating a combination of the change level and the number of times is set by operating the up / down lever 28. The combination of the change level and the number of times is set in S2607 of FIG. 26, and the display is performed in S1912 of FIG. 19B.

[Setting of Presence / Absence of Focusing Sound] FIGS. 67A and 67B are displays relating to the setting of whether or not to sound the electronic buzzer 108 at the time of focusing. A setting item [3] is displayed, and the character Sd is used to inform the operator that the sound is set. "1" is set when the electronic buzzer 108 is sounded, and "0" is set when it is not sounded. Since it is difficult to know which one is set only by the flag alone, when "1" is set, the electronic buzzer 108 should be sounded at a predetermined time interval with the display in Fig. 67B. The operability is improved. The setting is performed in S2609 of FIG. 26, and the display and driving of the electronic buzzer 108 are performed in S1923 of FIG.

68A to 68F show modifications of the display relating to the setting of the electronic buzzer 108 at the time of focusing. In this modified example, when "1" is set to the flag indicating that the electronic buzzer 108 sounds, the Sound character string is divided and sequentially displayed, so that the electronic buzzer 108 is set to sound when focused. It indicates that there is. This Sound display normally uses a 2-digit display area consisting of 7 segments each for displaying the Av value, and it is not necessary to provide a segment for displaying the alphabet. The flag is set in S2609 of FIG. 26, and the display is performed in S1923 of FIG.

[Selection of Learning Function] FIGS. 69A and 69B are settings for whether or not to learn the program shift. [4], which indicates the selection item, is displayed. When learning is performed (that is, when the learning prohibition flag is set to "0"), a picture display such as NOTEBOOK makes it easy to understand the settings. I have to. The learning function is selected in S2611 of FIG. 27, and the display is S1925 of FIG. When the flag is changed from "learn" to "not learn" after learning, the learned program shift amount is not cleared but fixed.

“Clearing Learning Contents” FIGS. 70A and 70B show displays for clearing the learned contents. The selection item [5] is displayed, and the picture of the note and the character CL blink. In this state, operate the up / down lever 28 to select any one or all four of the four modes in which the learning function is valid, and press the Tv / Av button 30 to set the data clear. Is completed. When learning clear is set, as shown in FIG. 70B, the picture of the note disappears and the character CL is changed to a lighting display. The setting is performed in S2613 of FIG. 26, and the display is performed in S1927 of FIG.

[Selection of Exposure Mode] FIGS. 71A to 71E are displayed on the external display LCD panel 34 when the up / down lever 28 is operated while pressing the mode button 40 when the main button 36 is at the PICT position. The display content is shown. 71A, 71B, 71C, 71D, and 71E in this order correspond to the green mode, portrait mode, distant view mode, moving object mode, and proximity mode. 71F shows the in-viewfinder LCD display panel 62 in the person / distant view / proximity mode, FIG. 71G shows the moving object mode display, and FIG. 71H shows the green mode display.

[Display Example of Exposure Correction in PICT Mode] FIGS. 72A and 72B show display examples when the main button 36 is at the PICT position (for example, when the person mode is selected). FIG. 72A shows a display on the viewfinder display LCD panel 62. The amount of program shift is indicated by a scale and dot display. Further, the Tv value / Av value calculated based on the shifted program is displayed above. FIG. 72B shows a display on the external display LCD panel 34. On the external display LCD panel 34, in addition to the information on the in-viewfinder display LCD panel 62, the number of films, the drive mode (shooting mode), and the picture in the AE mode are displayed.

When the hyper button 52 is pressed in the above state, the exposure correction is displayed. 73A and 73B show the display on the viewfinder display LCD panel 62 and the external display LCD panel 34 in the state where the exposure correction is performed. In this example, the exposure correction is -2.0 Ev. As for the scale on the display panel, 1 scale is 0. Since it corresponds to 5 Ev and the center of the scale corresponds to exposure compensation 0, in this example, the dot is lit at the minus end of the scale. The external display LCD panel 34 is adapted to display a numerical value of the correction value.

In the camera of this embodiment, the exposure correction value is -2.0 Ev to +2. It is 0 Ev. However, in reality, the exposure correction value can be set in the range of −3.0 to +3.0 Ev beyond the range of the graph (see FIG. 28). For this reason, when the correction value exceeds the range of the graph, it blinks at the end point of the graph on the exceeded side. 74A and 74B show examples when the exposure correction value is -2.5. In this case, the black circle blinks at the minus side end point. 75A and 75B show an example in which the exposure mode is displayed and the exposure mode is displayed by releasing the finger from the hyper button 52. The "-" mark that indicates that the exposure compensation is on the negative side is lit. Further, when the Tv / Av button 30 is pressed while pressing the hyper button 52, the set exposure correction value is reset to zero.

[Display Example of Exposure Compensation in Program Mode] FIGS. 76A, 76B, 77A, 77B, 78A, and 78B show normal displays when the exposure mode is the program mode (FIGS. 76A and 76B). ), Display during exposure compensation (FIGS. 77A and 77B), and display after exposure compensation value setting (FIGS. 78A and 78B). In the normal display, the display consisting of scales and dots is not displayed, but once the exposure compensation value is set, the exposure compensation amount is displayed as a graph in the normal display state. Even in the exposure correction in the program mode, the exposure correction value can be set beyond the display range of the graph as in the case described above, and in that case, a black circle blinks at the end point of the graph. The blinking display of the black circle is also performed when the finger is released from the hyper button 52 and the normal display state is achieved. Also, the program shift is possible in the program mode, and when it is shifted, an overline is displayed on the Tv / Av display portion of the external display LCD panel 34 and the Tv of the in-viewfinder display LCD panel 62 is displayed. Values and Av values are underlined (when the shift amount is 0, overlines / underlines are not displayed).

“Display Example of Exposure Compensation in Auto Mode” FIGS. 79A, 79B, 80A, 80B, 81A, and 81B show the normal display when the exposure mode is the auto mode (FIGS. 79A and 79B). ), Display during exposure compensation (FIGS. 80A and 80B), and display after exposure compensation value setting (FIGS. 81A and 81B). In normal display, the display consisting of scales and dots is not displayed. In addition, whether the Tv value or the Av value can be changed by operating the up / down lever 28 (that is, whether shutter priority or aperture priority is given) is displayed on the external LCD panel 34. In the above, Tv or Av is indicated by being displayed with an arc-shaped overline, and on the viewfinder display LCD panel 62, the Tv value or Av value is indicated by underlining. The setting of which of the Tv value and the Av value can be changed can be switched by operating the Tv / Av button 30.

The exposure correction is the same as in the program mode described above. Even in the exposure correction in the auto mode, the exposure correction value can be set beyond the display range of the graph as in the above case, and in that case, the black circle blinks at the end point of the graph. The blinking display of the black circle is performed even when the user releases the finger from the hyper button 52 and enters the normal display state.

[Graph Display in Manual Mode] FIGS. 82A, 82B, 83A, 83B, 84A, and 84B show the Tv value by the up / down lever 28 when the exposure mode is the manual mode. Display when setting (Figure 82A, Figure 82B), display when setting Av value (Figure 83A, Figure 83B), display when proper exposure is set (Figure 84A, Figure 84B). Show.

In the manual mode, when the Tv value can be changed by the up / down lever 28, an arc overline is added to the Tv display of the external display LCD panel 34, and the inside of the viewfinder is displayed. The Tv value is displayed on the display LCD panel 62 with underlining (FIGS. 82A and 82B). On the other hand, in the cases of FIGS. 83A and 83B, the Av value / Av display is underlined / overlined. In the manual mode, there is no exposure compensation, but in the normal display state, the graph display with scales and dots is performed. In the camera of this embodiment, the AE calculation is performed even in the manual mode. With the center of the displayed scale as the proper exposure value for calculation, if the set value is overexposed, a dot is displayed on the "+" side of the scale. One scale corresponds to 0.5 Ev, and in the case of FIGS. 82A and 82B, overexposure of 1.0 Ev is obtained. It should be noted that the scale can be displayed with dots in the range of -2.0 Ev to +2.0 Ev centered on the proper exposure value. When this range is exceeded, as shown in FIGS. 83C and 83D, the “-” mark blinks to indicate that the range is underexposed (in the drawings). A radial line around the "-" mark means that the "-" mark is flashing. The mark is designed to blink.

84A and 84B are diagrams showing a case where the manually set exposure value and the calculated exposure value match. To match the manually set value with the calculated exposure value, the set value may be changed by operating the up / down lever 28 to reduce the number of displayed dots. In the camera of this embodiment, in addition to this, by pressing the hyper button 52 in the manual mode, the proper exposure value obtained by calculation is set.

“AE Calculation” Next, the processing by the AE (automatic exposure mode) calculation subroutine called in S1319 in “RESTART” shown in FIGS. 13A and 13B and S1415 in “release processing” shown in FIG. This will be described with reference to the flowcharts shown in FIGS. 41A, 41B, 41C and 41D.

In the present embodiment, as the exposure mode, a green mode, a portrait mode, a landscape mode, a moving object mode, and a proximity mode whose settings can be changed when the main button 36 is switched to the PICT position and the pict switch 110b is turned on. In addition, a normal program mode in which the setting can be changed when the main button 36 is switched to the ON position and the on switch 110a is turned on (a normal shutter speed and an aperture value are automatically set based on a photometry result) Program automatic exposure mode), auto mode (lens auto shutter speed priority automatic exposure mode that automatically sets the aperture value from the manually set shutter speed and photometric results, and the shutter speed from the manually set aperture value and photometric results). (Aperture-priority automatic exposure mode that is set automatically), and manual exposure Although not shown, it has a lens manual aperture priority automatic exposure mode, a manual exposure mode, and a bulb exposure mode.

In the AE processing, first, the RAM of the CPU 20 on the body side is initialized, various flags relating to photometry, etc. are initialized, and then the lens correction calculation subroutine is called (S4101 to 4105). In this lens correction calculation subroutine, in “lens communication” during the process of “RESTART” shown in FIG. 13A, based on the lens data of each type according to the type of the photographing lens input from the CPU 20 (FIG. 11) on the lens body side. Then, the lens correction calculation process is executed.

Next, the subject brightness data output from each sensor (light receiving element 94) for split photometry output from the A / D conversion circuit 98 is converted into calculation subject brightness Bv suitable for calculation, and further, The light intensity value Lv 'for each sensor is obtained from the subject brightness for calculation Bv and the lens correction value calculated in S4105, and the light intensity value Lv' for each sensor is applied to the subject based on the divided photometry algorithm. One suitable light quantity value Lv 'is calculated (S4107 to S4111).

Then, the light amount value Lv is obtained based on the calculation film sensitivity Sv and the calculation exposure correction value Xv which are converted in advance so as to be suitable for calculation, and the value corresponding to the currently set AE mode (number) is set to X. (S4113, S4115).

In S4117, the coefficients a, b, TvL1 etc. corresponding to each AE mode entered in X are set. These coefficients a, b, TvL1 and the like are preset and input in the ROM of the body side CPU 20, and are read into the RAM as needed.

In the “person mode (the outline of the program line is shown in FIG. 48A)” branched at X = 1, 2/8 is put in the coefficient a which is the inclination of the program line, and 5 6/8 is put in the coefficient b. Put in. Further, the camera shake limit Tvf is set in the first Tv boundary TvL1, the photographing optimum Av value Avf is set in the first Av boundary AvL1, and the minimum aperture value AvMIN is set in the second Av boundary AvL2. Call.

In the “landscape mode (the outline of the program line is shown in FIG. 49A)” branched at X = 2, 2/8 is put in the coefficient a and the landscape coefficient b is put in the coefficient b. The landscape coefficient b is calculated by (6/8) × Tvf− (2/8) × (AvMIN +1). Further, the minimum shutter speed TvMIN is input to the first Tv boundary TvL1, the minimum aperture value AvMIN + 1 is input to the first Av boundary AvL1, the minimum aperture value AvMIN is input to the second Av boundary AvL2, and the program is executed in S4143. Call the arithmetic subroutine.

In the “moving body mode (the outline of the program line is shown in FIG. 50A)” branching at X = 3, 2/8 is put in the coefficient a and 5 6/8 is put in the coefficient b. Further, the camera shake limit Tvf + 1 is entered in the first Tv boundary TvL1, the minimum aperture value AvMIN + 1 is entered in the first Av boundary AvL1, the minimum aperture value AvMIN is entered in the second Av boundary AvL2, and the program calculation subroutine is executed in S4143. To call.

In the “proximity mode (the outline of the program line is shown in FIG. 51A)” branched at X = 4, 2/8 is put in the coefficient a and 5 6/8 is put in the coefficient b. Further, the camera shake limit Tvf is entered in the first Tv boundary TvL1, Av6 (F = 8) is entered in the first Av boundary AvL1, and the minimum aperture value AvMIN + 1 is entered in the second Av boundary AvL2, and S4143 is entered. To call the program calculation subroutine.

In the program calculation subroutine called in S4143, the control Tv and the control Av that are actually used in the control are calculated based on the Tv value and the Av value set for each mode, which will be described in detail later.

On the other hand, when branching to the “green mode” when X = 1, the program shift prohibition flag is set to “1” and the program line is prohibited in advance so as not to be shifted. Then, the normal program subroutine is called (S4135, S4137), and in this mode, the control Tv and the control Av actually used for control are obtained.

When branching to the “normal program mode” when X = 5, the normal program subroutine is called without setting “1” in the program shift prohibition flag (S4137).

Further, when branching to the “AUTO mode” when X = 6, the AUTO operation subroutine is called (S4139), and when branching to the “manual mode” when X = 7, the manual operation subroutine is called. Yes (S4141).

Furthermore, whether or not the control Tv and the control Av obtained in the mode selected in S4117 are values that can be used for control is called by the CHK. It is checked by the TvAv subroutine, and if it exceeds the controllable value, it is converted to its maximum value or minimum value (S4145). And CHK Data such as whether the EE pulse number is obtained based on the Tv value and Av value finally determined by the TvAv subroutine, and whether or not the external flash fires, how much light is emitted, and whether the rear curtain synchronization is performed. Is sent (S4147, S4149). The EE pulse is a pulse used to stop the diaphragm in response to the control diaphragm value Av. After that, in step S4151, a quench signal is output during flash photography to set TTL data for stopping the flash emission, and the process returns.

The normal program subroutine shown in S4137 of FIG. 41C will be described with reference to the flowchart shown in FIG. 52A. The program diagram described in this subroutine is shown in FIG. 52B, for example, and its features are as follows. The shake limit Tvf (= TvL1) is set. It is set so as to be located between the program line (see FIG. 49B) relating to the landscape mode where importance is attached to the depth of field and the program line (see FIG. 50B) relating to the moving object mode where importance is attached to the shutter speed. When the camera shake limit Tvf (= TvL1) is exceeded, it is set so that the program shift of at least one step is possible.

[0145] As shown in the figure, camera shake is likely to occur near the camera shake limit Tvf (= T vL1) at f = 80 mm and f = 28 mm, so in the low Ev range where Tv <Tvf, the camera shake limit Tvf The shutter speed is fixed and the aperture is opened to the minimum aperture value. When the aperture value reaches the maximum aperture value, the shutter speed is slowed down while keeping the aperture open. The camera shake limit Tvf (= TvL1) at this time is substituted for the variable TvL1 and processed.

In the normal program subroutine, first, the fv arithmetic subroutine shown in FIG. 42A is called, and the focal length f is converted corresponding to the apex value by fv = log (focal length f) / log2. Find fv.

Subsequently, in S5203, the calculation Tv is obtained by Tv = (3/8) × light quantity value Lv + normal coefficient b normal coefficient b = (5/8) Tvf− (3/8) (AvMIN +1). In this calculation formula, for example, in the program diagram of FIG. 52B, the program line is moved in the shutter axis direction along with the change of the normal coefficient b while fixing the inclination.

Then, it is checked whether or not the calculation Tv obtained in S5203 is higher than the maximum shutter speed TvMAX. If it is larger, the maximum shutter speed TvMAX is stored in the RAM of the CPU 20 on the body side as the calculation Tv, and the shutter to be actually set is set. Although the speed is faster, the Tv over flag is set to "1" to indicate that the maximum shutter speed TvMAX has been entered in the calculation Tv (S5205, S5219, S5221).

Further, the CAL of FIG. Since the Av subroutine is called and the calculation Tv is changed, an appropriate calculation Av corresponding to this calculation Tv is obtained (S5223), and the flow proceeds to S5215. If the calculation Tv is less than or equal to the maximum shutter speed TvMAX in S5205, the calculation Tv is compared with the camera shake limit Tvf. If the calculation Tv is smaller than the camera shake limit Tvf, the camera shake limit Tvf is stored in the RAM as the calculation Tv. (S5207, S5225), the process proceeds to S5209. In S5207, when the calculation Tv is larger than the camera shake limit Tvf, the processing proceeds to S5209.

In S5209, the CAL of FIG. The Av subroutine is called, an appropriate calculation Av corresponding to the calculation Tv set here is obtained, and the flow proceeds to S5211. In S5211, the Av over flag is checked, and if "1" is set in this Av over flag, CAL is performed. Since the Tv subroutine is called and the calculation Av has been changed, an appropriate calculation Tv corresponding to this calculation Av is obtained (S5227), and the flow proceeds to S5215. If "0" is set in the Av over flag, the flow advances to S5213 to check the Av under flag. CAL when Av Under Flag is set to "1" The Tv subroutine is called, an appropriate calculation Tv corresponding to the calculation Av is obtained in accordance with the change of the calculation Av (S5227), and the process goes to S5215.

Then, in S5215, the normal P shift calculation subroutine shown in FIG. 46 is called to check whether or not there is a program shift. That is, in S4602, the program shift amount set by the photographer by the up / down lever 28 is entered as the total program shift amount, and in S4604, the P shift direction bit set by the direction of the program shift is changed to the total P shift direction bit. Then, the process proceeds to S4602, S4604, S4603, and the P shift prohibit flag is checked. In this embodiment, since the program shift is not performed in the green mode, when the green mode is selected by X = 0 in the AE calculation of FIGS. 41A, 41B, 41C and 41D, “1” is set in the P shift prohibition flag. Therefore, it is determined that there is no program shift and the process returns in S4603. Further, since the program shift is performed in the normal program (P) mode, when this mode is selected by X = 5, S4135 is jumped and "1" is not set to the P shift prohibition flag. Therefore, the program is checked as having a program shift, and the process proceeds to the previous step without returning in S4603.

Then, in S5217, the calculated calculation Tv is converted into a value that is actually used in control, is stored in the RAM of the body side CPU 20 as the control Tv, and the calculated calculation Av is converted into a value that is actually used in control. Then, it is put in the RAM as the control Av and returns.

Next, the AUTO operation subroutine shown in S4139 of FIG. 41C will be described with reference to the flowchart shown in FIG. First, in S5301, the TvAv mode flag that should be set in S2521 of the data U / D subroutine of FIG. 25 is checked. If this TvAv mode flag is set to "1", aperture priority is selected. If the shutter speed priority is selected, the flow advances to S5303. If "0" is set, the flow advances to S5303.

When the shutter speed is prioritized, the manually set setting Tv is put into the control Tv actually used for control (S5303). Then, the setting Tv is converted into a value for calculation and is input into the calculation Tv, and CAL is entered. The Av subroutine is called, an appropriate calculation Av corresponding to the calculation Tv is calculated, the calculation Av is further put in the control Av (S5305 to S5309), and the process returns. When the aperture is prioritized, the setting Av is put in the control Av (S5311), the setting Av is put in the calculation Av, and CAL is performed. The Tv subroutine is called to calculate an appropriate calculation Tv corresponding to the calculation Av, this calculation Tv is put in the control Tv (S5313 to S5317), and the process returns.

The manual subroutine shown in S4141 of FIG. 41C will be described with reference to the flowchart shown in FIG. First, in S5401, the TvAv mode flag that should be set in S2521 of the data U / D subroutine in FIG. 25 is checked. If this TvAv mode flag is set to "1", the aperture by the up / down lever 28 is reduced. Since the value can be set, the flow proceeds to S5419. If "0" is set, the shutter speed can be set by the up / down lever 28, and the flow proceeds to S5403.

When setting the shutter speed, the setting Tv set by the 1/2 series value processed in steps of 1/2 is put into the control Tv, and the setting Av set by the same 1/2 series value is set. It is put into the control Av (S5403, S5405). Here, the on / off of the hyper (exposure correction) switch 52 is checked, and if the hyper switch 52 is not on, the process returns with the 1/2 series value. Therefore, in this case, the photographing is performed by the control Tv and Av based on the value processed in the manually set 1/2 step.

On the other hand, when the hyper switch 88 is turned on in order to obtain the proper exposure value based on the photometric value, the setting Tv of 1/2 series value is calculated in steps of 1/8. Convert to Tv, CAL The Av subroutine is called to obtain an appropriate calculation Av corresponding to this calculation Tv, and the calculation Av processed in 1/8 step is put into the control Av actually used for control (S5409 to S5413). As described above, in the manual exposure mode, when the hyper button 52 is pressed and the hyper switch 88 is released while the release is performed, the exposure is performed based on the value calculated by the body side CPU 20 in 1/8 steps with high accuracy. be able to.

Further, since the calculation Av is put into the set Av, the sequence Av is processed into 1/2 series (S5415 to S5417) and the process returns, so that the Av value after this is manually up / down by the 1/2 series value.

The 1 / 2-series processing is performed in steps of 1/2 at the time of manual calculation, whereas it is processed in steps of 1/8 at the time of automatic calculation. Since the step of the apex value set by the calculation of the CPU 20 is smaller than the step of the apex value that can be manually set, it means to round the calculated apex value to the half step of the manually set apex value. .

When the aperture is manually set, the setting Av set by the 1/2 series value processed in steps of 1/2 is put into the control Av, and the setting Tv set by the same 1/2 series value is controlled. Put in Tv (S5419, S5421). Here, it is checked whether the hyper switch 52 is on or off, and if the hyper switch 88 is not turned on, the process returns with the 1/2 series value. Therefore, in this case, photographing is performed by the control Av and the control Tv based on the manually set value processed in steps of 1/2.

On the other hand, when the hyper switch 88 is turned on, the ½ series value setting Av is converted into a calculation Tv processed in steps of ⅛, and CAL is converted. The Tv subroutine is called to obtain an appropriate calculation Tv corresponding to this calculation Av, and the calculation Tv processed in 1/8 step is put into the control Tv actually used for control (S5 425 to S5429). ). As described above, in the manual exposure mode, when the hyper button 52 is pressed and the hyper switch 88 is turned on and the shutter is released, the exposure is performed based on the value calculated by the body CPU 20 in highly accurate steps of 1/8. be able to.

Further, since the calculation Tv is set in the set Tv, and this is converted into a 1/2 series processing (S5431 to S5433) and the process returns, the Av value after this is manually increased / decreased by the 1/2 series value.

[Program Calculation] Next, the program calculation subroutine shown in S4143 of FIG. 41B will be described with reference to the flowcharts of FIGS. 42A and 42B. In this subroutine, the calculation Tv and the calculation Av are calculated according to the mode set by the mode setting operation among the portrait mode, the landscape mode, the moving object mode, and the proximity mode, and the control Tv actually used in the control is calculated. And control Av.

First, in step S4201, the fv calculation subroutine is called, and the focal length f 2 input from the focal length detection mechanism 102 of the taking lens 12 can be used as an apex value by the formula fv = log (focal length f) / log2. To obtain a converted focal length fv. Furthermore, the Tvf calculation subroutine is called, and the camera shake limit Tvf of the shutter speed is obtained from the equation Tvf = (3/4) × fv + 2 (S4203). Further, the Avf calculation subroutine is called, and Avf = AvMIN + 1 + Avf shift Avf shift = (5/4) × (6.5−fv), where 0 ≦ Avf shift ≦ 2 is used to obtain the optimum shooting Av value Avf. The optimum Av value Avf is a value for determining the optimum aperture value based on the focal length when you want to blur the background or when you want to take a clear picture with a deep depth of field. In other words, it is the absolute amount of how much to narrow down from opening.

In S4207, the calculation Tv is obtained by the equation of coefficient a × light quantity value Lv + coefficient b using the coefficients a and b corresponding to each AE mode set in S4119 to S4133 of FIG. 41B.

This calculation Tv at the predetermined focal length of the selected mode is compared with the minimum shutter speed TvMIN and maximum shutter speed TvMAX specific to the camera, respectively (S 4209, 4211). If the above calculation Tv is smaller than the minimum shutter speed TvMIN, this minimum shutter speed TvMIN is put into the calculation Tv, and it is assumed that the minimum shutter speed TvMIN is set even if the shutter speed slower than that is actually set. , Tv under flag is set to "1" (S4213), and the process proceeds to S4217. If the above calculation Tv is larger than the maximum shutter speed TvMAX, this maximum shutter speed TvMAX is put into the calculation Tv, and it is assumed that the maximum shutter speed TvMAX is set even if the shutter speed which is faster than that is actually set. , Tv over flag is set to "1" (S4215), and the process proceeds to S4217.

If the calculation Tv at the predetermined focal length in the selected mode is equal to or higher than the minimum shutter speed TvMIN and equal to or lower than the maximum shutter speed TvMAX in S4209, the Tv under flag and the Tv over flag are both set to "1". Without setting ", proceed to S4217. In S4217, the CAL shown in FIG. The Av (Av operation) subroutine is called to obtain an appropriate operation Av corresponding to the operation Tv based on the operation Tv.

In S4219, CAL It is checked whether or not the calculation Av set by the Tv subroutine exceeds the first Av boundary AvL1 calculated by the selected mode. As a result, if the operation Av exceeds the first Av boundary AvL1, the process jumps to S4243 to execute the P shift operation process, check the direction and amount of the program shift, and perform the operation suitable for the program to be shifted. Calculate Tv and operation A v. If the operation Av is less than or equal to the first Av boundary AvL1, the process proceeds to S4221 to put the first Av boundary AvL1 into the operation Av. This determines the Av value, so CAL The Tv subroutine (FIG. 43) is called to obtain the Tv value according to this calculated Av value (S4223).

In S4225, the calculation Tv obtained in S4223 is further compared with the first Tv boundary TvL1 calculated in S4203. As a result, if the calculation Tv exceeds the first Tv boundary T vL1, the process jumps to S4243 to execute the P shift calculation process, check the direction and amount of the program shift, and calculate the calculation Tv suitable for the shifting program. And the calculation Av is obtained. If the calculation Tv is less than or equal to the first Tv boundary TvL1, the process proceeds to S4227 and the value of the first Tv boundary TvL1 is put into the calculation Tv. Since the Tv value is determined by this, in S4229 CAL The Av subroutine is called again, and the operation Av corresponding to this operation Tv is calculated.

Further, it is checked whether or not the calculated Av value is larger than the second Av boundary AvL2 (S4231), and if the calculated Av exceeds the second Av boundary AvL2, jump to S4243. If not, the process proceeds to S4233 and the value of the second Av boundary AvL 2 is set as the calculation Av. Since the calculation Av is determined by this, in S4235, CAL is performed. The Tv subroutine is called again to calculate the calculation Tv according to the calculation Av. Further, this calculation Tv is compared with the minimum shutter speed TvMIN (S4237). If the calculation Tv is larger than the minimum shutter speed TvMIN, the process jumps to S4243, and if not, this minimum shutter speed TvMIN is entered into the calculation Tv. This determines the Tv value, so CAL The Av subroutine is called again (S4241), and the calculation Av corresponding to this calculation Tv is obtained.

In S4243, the P (program) shift calculation subroutine is called, the shift amount of the program line preset and input to ROM is obtained, and further, the calculation Tv is set as the control Tv actually used for control, Further, the calculation Av is set as the control Av actually used for control (S4245), and the process returns.

“CAL Tv ”Next, according to the flowchart of FIG. 43, CAL is a process of setting an appropriate Tv value and regulating the Tv value within a controllable range. The Tv (Tv calculation) subroutine will be described. First, the Tv under flag and the Tv over flag are cleared (S4301), and the value obtained by the formula of light amount value Lv-calculation Av is put into the calculation Tv (S4303).

This calculation Tv is compared with the minimum shutter speed TvMIN and the maximum shutter speed TvMAX peculiar to the camera (S4305, 4307). As a result, if the calculation Tv is smaller than the minimum shutter speed TvMIN, this minimum shutter speed TvMIN is set as the calculation Tv, and the shutter speed slower than that is actually set, but the minimum shutter speed TvMIN is set. If so, the Tv under flag is set to "1" (S4309), and the process returns. If the calculated Tv is larger than the maximum shutter speed TvMAX, the maximum shutter speed TvMAX is set to the calculated Tv, and the maximum shutter speed TvMAX is set although the shutter speed must be set higher than that actually. As a result, the Tv over flag is set to "1" (S4311), and the process returns.

In S4305, if the calculation Tv is equal to or higher than the minimum shutter speed TvMIN, the process proceeds to S4307, and if the calculation Tv is equal to or lower than the maximum shutter speed TvMAX, the process returns. Therefore, this CAL The Tv subroutine limits the shutter speed used in the AE calculation program shift to a controllable range.

“CAL Av '' Next, according to the flowchart of FIG. 44, CAL is a process of setting an appropriate Av value and regulating the Av value within a controllable range. The Av (Av operation) subroutine will be described. First, in S4401, the Av under flag and the Av over flag are cleared, and the value obtained by the light amount value Lv-calculation Tv is set in the calculation Av (S4403).

This calculation Av is compared with the minimum aperture value AvMIN and the maximum aperture value AvMAX (S4405, 4407). As a result, if the calculation Av is smaller than the minimum aperture value AvMIN, the minimum aperture value AvMIN is set to the calculation Av, and it is assumed that the minimum aperture value AvMIN is set even though the aperture must actually be narrowed down. 1 "is set (S4409), and the process returns. If the calculation Av is larger than the maximum aperture value AvMAX, the maximum aperture value AvMAX is set to the calculation Av, and the maximum aperture value AvMAX is set even if the aperture has to be actually increased. Is set to "1" (S4411) and the process returns.

In S4405, if the calculation Av is equal to or larger than the minimum aperture value AvMIN, the process proceeds to S4407, and if the calculation Av is equal to or smaller than the maximum aperture value AvMAX, the process returns. Therefore, this CAL The Av subroutine limits the aperture value used in the AE calculation program shift to a controllable range.

"P Shift Calculation" The P (program) shift calculation subroutine shown in FIGS. 42A and 42B will be described with reference to the flowchart shown in FIG. First, in step S4601, the sub-P shift subroutine is called to obtain the shift amount and shift direction of the learning program line. Thus, when the total program shift amount is obtained, the P shift prohibition flag is checked (S4603), and if "1" is set in the P shift prohibition flag, the process returns and the program shift is not performed. If the flag is set to "0", the flow advances to S4605 to check whether the entire program shift amount is 0. If the total program shift amount is 0, that is, if it is determined that the program line need not be shifted, return. If not, that is, if the program line is shifted, check all P shift direction bits. Then, the shift direction is determined (S4607).

As a result, if all P shift direction bits are set to “1”, the shift direction is negative, that is, if the program line shown in FIGS. 48A and 48B is to be shifted in the upper left direction in the figure, the operation is performed. A value obtained by subtracting the total P shift amount from Tv is set in the calculation Tv, and the shutter speed is set to be slow (S4623). Further, it is checked whether or not this calculation Tv is smaller than the minimum shutter speed TvMIN, and if it is smaller, the minimum shutter speed TvMIN is set in the calculation Tv (S4627), and if not so, the flow proceeds to S4615.

Further, in S4607, when all the P shift direction bits are set to “0”, the shift direction is positive, that is, the program line shown in FIGS. 48A and 48B is to be shifted to the lower right in the figure. Advances to S4609 to set a value obtained by adding the total P shift amount to the calculated Tv, and set the shutter speed to be high. Furthermore, it is checked whether or not this calculation Tv is higher than the maximum shutter speed TvMAX (S4611), and if it is larger, the maximum shutter speed TvMAX is set in the calculation Tv (S4613), and if not so, the processing proceeds to S4615.

In S4615, the CAL shown in FIG. The Av subroutine is called to calculate the operation Av, and in steps S4617 and S4619, the Av over flag and the Av under flag are checked. As a result, if the Av over flag is set to "1" and the Av under flag is set to "1", the flow proceeds to S4621 and CAL. The Tv subroutine is called, and the Tv value according to the calculation Av at that time is calculated. If "0" is set in both the Av over flag and the Av under flag, the process directly returns.

The program line shown in FIG. 48B shows the program line in the person mode described in FIG. 48A in more detail, and its characteristics are as follows. The first camera shake limit Tvf (= TvL 1) is set for both the wide side and the tele side. The wide side is set to be suitable for group photography and shooting of people in landscapes, and it is possible to express both landscapes and people sharply by narrowing down the aperture. The tele side is set to be suitable for portrait and bust-up shooting, and the aperture is opened to make people stand out. In the normal shooting area, the aperture control level is reversed.

As described above, the program line relating to the person mode is set to open the aperture from the low-speed shutter speed range to the camera shake limit on the wide side and the tele side, and fixes the shutter speed at the camera shake limit and stops the aperture. Since it is set to change to a predetermined value, it is possible to support not only portraits but also general portrait photography, and to provide a camera with a program line in portrait mode that also considers camera shake prevention. You can Also, the aperture value change at the limit of camera shake is set to 3 stops on the wide side and 1 stop on the tele side, so the wide side is suitable for group photos and shooting of people in landscapes. Can be set to, and both the landscape and people can be sharply expressed by narrowing down the aperture.

Further, the program line shown in FIG. 49B shows the program line in the landscape mode shown in FIG. 49A in more detail, and its characteristics are as follows. You can take in-focus shots regardless of the focal length from near to far. In the low-brightness range, the aperture is narrowed down from the open one step, and the aperture is prioritized. By narrowing down one step from the full aperture, the lack of peripheral light quantity is resolved and the image performance is improved.

As described above, in the landscape mode program line, the aperture is set so as to be narrowed from the low shutter speed range to near the camera shake limit by one step from the open aperture value at the focal length regardless of the focal length. . For example, at a focal length of 28 mm, the aperture is narrowed down by one step from AvL2 which is the maximum aperture value.

The landscape mode program line is set so that the exposure value Ev changes with a slope of 6/2 in the portion indicated by G after the shake limit. That is, as described above, Tv value = coefficient a × light quantity value Lv + coefficient b, and in landscape mode, 2/8 is added to the coefficient a in S4223, so when the light quantity value Lv increases by 1, the Tv value is increased. Is increased by 2/8. Further, since Av value = light amount value Lv−Tv value, when the light amount value Lv increases by 1, the Av value increases by 6/8. Therefore, the Av value and the Tv value change at a ratio of 6: 2, that is, the program line changes with a slope of 6/2. In the figure, the numbers in parentheses are the apex values corresponding to the shutter speed and the aperture, respectively. The apex values are shown in FIGS. 48B, 50B, 51B, 52B and 55C. Has the same meaning in.

Further, the program line shown in FIG. 50B shows the program line in the moving object mode shown in FIG. 50A in more detail, and its features are as follows. The third camera shake limit Tvf + 1 is set, and the camera shake limit Tv value is increased by one step from the first camera shake limit.

Further, the program line shown in FIG. 51B shows the program line in the proximity mode shown in FIG. 51A in more detail, and its characteristics are as follows. In the low-brightness range, both wide-side and tele-side have a program with a stop priority that is one stop narrower than full aperture. From the camera shake limit, it is set to F8 regardless of the focal length.

As described above, the program line related to the proximity mode is such that the aperture is fixed at a predetermined value from the low shutter speed range to the camera shake limit, and the aperture is changed by about one step at the camera shake limit and is fixed at F8, Since it is set to control after the camera shake limit in F8, it is possible to obtain a camera having an exposure mode applicable not only to the macro range of the zoom lens but also to the macro lens as a close-up mode. Further, the diaphragm can be set to a value slightly raised or lowered from F8. Further, in close-up photography, the depth of field becomes shallow and the shutter speed becomes slow due to excessive narrowing down, and camera shake and subject shake are likely to occur.However, in the present embodiment, the shutter speed is set at the camera shake limit where camera shake is most likely to occur. Since the aperture value is fixed and the aperture value is narrowed down by approximately one step and the aperture value is controlled after the camera shake limit, the above-described camera shake and object shake can be avoided.

"Sub P Shift" Here, the sub P shift subroutine shown in S4601 of FIG. 46 will be described with reference to the flowchart shown in FIG. In this subroutine, the shift amount of the origin and the shift amount of the program line by learning, that is, the shift amount of the entire program is obtained.

In S4501, the five modes of the green mode, portrait mode, landscape mode, moving mode, and proximity mode that can be changed when the main switch 110 is switched to the picture position are set to X = 0 to 4. Since they are set correspondingly, the person mode (FIGS. 48A and 48B), the landscape mode (FIGS. 49A and 49B), the moving object mode (FIGS. 50A and 50B), and the proximity mode in which the program line should be actually shifted. When selecting (FIGS. 51A and 51B), a value obtained by subtracting 1 from the five AE mode numbers corresponding to X = 0 to 4, that is, AE mode-1 is set to X.

Further, the origin shift amount and the origin direction bit corresponding to the respective read values are read from the RAM (S4503, S4505), and the P shift direction bit is checked to confirm that the program shift direction is positive. Whether it is present or negative is checked (S4507). If it is positive, the process jumps to S4511, but if it is negative, it is determined that the program shift amount is negative, and this is negatively converted, that is, the absolute value is converted to a negative value (S4509).

In S4511, how the origin is changed by "learning" is checked by the origin direction bit. As a result, if the origin shift direction is negative, the origin shift amount that has undergone negative conversion, that is, absolute value processing, is used by converting it to a negative value, and if the origin shift amount is positive, it is used without being negatively converted. (S4513).

Then, the shift amount of the entire program line is obtained by adding the origin shift amount to the program shift amount (S4515). Further, in S4517, it is checked whether or not the overall shift amount is smaller than 0, and if it is smaller, the process proceeds to S4517, the whole program shift amount is subjected to absolute value processing, and “1” is set to all P shift direction bits. set. If the total shift amount is 0 or more in S4515, the process returns. Note that the above absolute value processing prevents the value of the exposure factor for calculation from becoming negative, aligns the precision of each exposure factor to 1/8 Ev steps, and adds and subtracts without considering the precision of the calculation. To facilitate the apex operation of.

[CHK TvAv ”CHK, which is a process of detecting whether or not the calculation Tv and the calculation Av are the limit values shown in S4145 of FIG. 41D. The TvAv subroutine will be described with reference to the flowchart shown in FIG. First, in S5701, it is determined whether or not the control Tv value calculated in each mode is equal to the maximum shutter speed TvMAX. If they are equal, the maximum shutter speed TvMAX flag is set to "1" (S4703). Otherwise, jump to S4705. In S4705, it is determined whether or not the control Tv value calculated in each mode and the minimum shutter speed TvMIN are equal. If they are equal, the minimum shutter speed TvMIN flag is set to "1" (S4707), and Otherwise, jump to S4709.

In S4709, it is determined whether or not the control Av value calculated in each mode and the maximum aperture value AvMAX are equal, and if they are equal, the maximum aperture value AvMAX flag is set to "1" (S4711). Otherwise, jump to S4713. In S4713, it is determined whether the Av value for control calculated in each mode and the minimum aperture value Av MIN are equal, and if they are equal, the minimum aperture value AvMIN flag is set to "1" (S4715), Otherwise it returns. "Learning"

Next, the processing related to learning, which is a feature of the present invention, will be described with reference to FIGS. 55 to 59 and 85 to 90. The learning of the present invention relates to the program shift situation in the program exposure mode. In other words, the number of releases is counted when the photographer releases the program while shifting the program according to his or her preference, and when the number of counts exceeds a certain number, the program line is moved in the shift direction. The data that is shifted by a predetermined amount is saved as learning data. After this storage, the shutter speed and aperture value along the learning program line obtained based on this learning data are set, and the program shift and learning storage are executed with this learning program line as a reference. is there.

The program shift in this embodiment changes the combination of the shutter speed and the aperture value by translating the program line (default program line) obtained by the normal program exposure process along the exposure value Ev line. Say that. For example, in the program diagram of the taking lens with the open F value of 3.5 and the minimum aperture F value of 22 shown in FIG. 55C, the default program line is set to 0.5 Tv or 1. A program shift of 0 Tv results in a program line or, and a program shift of 0.5 Tv or 1.0 Tv in the negative direction causes a program line or. However, when the shutter speed or aperture value exceeds the controllable range, for example, Ev = 9, and in the case of the learning program line, the aperture value has reached the open value, so program shift cannot be performed in the positive direction from here. I don't learn. When the shutter speed Tv is added by a predetermined value, the aperture value Av is subtracted by a predetermined value.

In addition, the point on the default program line is set as the origin, and moving this origin to the learning program line along the exposure value Ev line is called origin movement, origin shift, and the shutter speed Tv that changes due to this origin movement. The movement amount is called the origin movement amount or shift amount, the direction of the learning program line from the default program line is called the origin direction, and the point on the learning program line is called the learning origin. Although a simple program diagram is shown in FIG. 55C in order to facilitate understanding of the program shift operation of the present invention, the present invention is not limited to this, and in the present embodiment, portrait mode and landscape mode. , Program shift and learning can be performed in moving mode and proximity mode, respectively.

In this single-lens reflex camera, the program (P) shift amount and the program (P) shift direction are set by operating the up / down lever 28 (up, down switch 78, 80) (see FIG. 27), and metering is performed. When the switch 70 is turned on, the shutter speed Tv obtained by the normal program calculation processing is changed by the program shift amount, and the proper aperture value A v is set again based on the changed shutter speed Tv and the proper exposure value Ev. This is a configuration for calculating. In the present embodiment, an independent learning function is provided for each of the four program exposure modes of portrait mode, landscape mode, moving object mode, and proximity mode, and when any one of the four exposure modes is selected. , The learning function works independently.

FIGS. 58 and 59 show various data necessary for the learning function, areas of the EEPROM 106 and the RAM for storing these data, the data format and their relation, and the RAM format. The data necessary for learning includes the origin shift amount, the origin direction, the number of learning releases, the learning previous direction, the program shift amount, and the program shift direction.

The program shift amount is an absolute value of the shutter speed Tv shifted from the reference program line, and is positive (+) on the high speed shutter side (including 0) and negative (-) on the low speed shutter side. ) Is identified by the P shift direction bit (positive is “0”, negative is “1”). The reference program line is based on the learning program line when the learning result is saved, and is based on the default program line when it is not saved. The origin shift amount is the difference between the shutter speed Tv on the learning program line saved by learning and the shutter speed Tv on the default program line. The magnitude is expressed as an absolute value, and the learning program is based on the default program line. If the line is on the high-speed shutter side of the default program line is positive, and if it is on the low-speed shutter side, it is negative. The number of learning releases is incremented every time the exposure is completed, with the condition that the current program shift direction and the previous program shift direction are the same, and the previous program shift direction is learned. Positive: “10”, negative: “01”).

As an area for storing four types of data of the above-mentioned origin shift amount, origin direction bit, learning release number, learning previous direction bit, two bytes {STDYCNT (for each of the four program exposure modes [STDYCNT ( X), GEN PSFT (X)} and 2 bytes corresponding to RAM {STDYCNT (X), GE NPSFT (X)} are prepared, and further 4 bytes are stored in RAM as a common data area (ALLPSFT, SETTPSFT, STDYCNT and GENPSFT). Is prepared. The program shift amount uses 0 to 6 bits of SETFSFT, the program shift direction uses the 7th bit of SETFSFT, the origin shift amount uses 0 to 6 bits of GENPS FT, and the origin direction bit uses the 7th bit of GENPSFT. , 0 to 5 bits of STDYCNT are used as the learning release number, and the sixth and seventh bits of STDYCNT are used as the previous learning direction bit. Further, the total program shift amount (program shift amount from the origin) uses 0 to 6 bits of ALLPSFT, and the total shift direction bit uses the 7th bit of ALLPSFT.

“Learning Display Mode” FIGS. 85 to 90 show display modes of the external display LCD panel 34 regarding the program shift state and the learning state when EV = 13. The display thereof is controlled by the P shift graph display processing of FIG. 29 based on the P shift display table of FIG. 85, 86, and 90, a black circle 58f on the origin mark 58h indicates a state where no learning is performed or a state where the learning program line matches the default program line. Further, FIG. 85 shows a state in which the program shift amount is 0, and only the black circle 58f on the origin mark 58h is lit. FIG. 86 shows a state in which the program shift amount is +1.0 Tv (-1.0 Av), and the blinking black circle 58f displays the shift value, and the black on the side opposite to the blinking black circle 58f. The circle 58f indicates the origin. FIG. 90 shows a state in which the program shift amount is −1.0 Tv (+1.0 Av), the blinking black circle 58f at the left end displays the shift value, and the black circle 58f at the right end displays the learning origin. There is. 87 to 89 show that the learning origin is +0.5 Tv (-0.5 Av), that is, the learning program line (data) shifted by +0.5 Tv (-0.5 Av) is stored. it's shown. 87 shows the state of +0.5 Tv program shift, FIG. 88 shows the state of shift amount of 0, and FIG. 89 shows the state of −1.5 Tv program shift. Although not shown, the LCD panel 62 in the viewfinder also displays the triangular mark 58h, the scale 58g and the black circle 58f corresponding to the triangular mark 58h, the scale 58g and the black circle 58f of the external display LCD panel 34 in a corresponding manner. Be done.

[Learning Calculation Process] The learning process will be described in more detail with reference to the flowcharts shown in FIGS. 55A and 55B are flowcharts relating to the learning calculation process, which is a subroutine called in step S1415 of the release process of FIG. In the present embodiment, the learning is saved, that is, the learning program line is changed when the learning release is performed a predetermined number of times by the program shift in the same direction.

In the learning calculation process, first, the learning RUN flag for controlling the lighting of the learning picture 56S is cleared, whether the learning mode is set (whether the learning mode flag is “1”), and whether the program shift amount is 0 or not. If the learning mode is not in the learning mode (learning mode flag is “0”) or the program shift amount is 0 in the learning mode as well, the learning release number is not counted and the release processing subroutine is returned (S5501. S5505).

When the learning mode flag is set and the program shift amount is not 0, the program shift amount is larger than the learning change level set in the learning change level changing process of FIG. 26 for counting the number of learning releases. If it is larger than the learning change level, the number of learning release times 1 is set to the number of change release times, and if it is less than the learning change level, the number of learning change times 2 is set to the number of change release times (S5503). , S5505 and S5507, S5509 or S5507, S5511).

Next, from the RAM areas STDYCNT (X) and GENPSFT (X) corresponding to the selected program exposure mode (AE mode number X minus 1), the origin shift amount, origin bit, learning The release number and the learning previous direction bit are read out, and the origin shift amount and the origin direction bit are stored in the RAM area GENPSFT, and the learning release number and the learning previous direction bit are stored in the RAM area STDYCNT (S5513 to S5521). Then, the learning RUN flag is set, the learning release number is added once, and it is checked whether the learning release number is less than the change release number. If less, the process proceeds to S5529 to count the learning release number. If there is, the process proceeds to the learning U / D process of FIGS. 57A and 57B for the learning up / down process (S5523 to S5527).

If the learning release number is less than the change release number, the program shift direction is not different from the previous program shift direction (learning direction) (P shift direction bit is “1” and learning previous direction bit is “01”). , Or the P shift direction bit is “0” and the learning previous direction bit is “10”), the process proceeds to the learning store 2 processing as it is (S5529, S5531 or S5529, S5553). In other words, the number of learning releases is incremented each time a release is performed when released in the same program shift direction (or the shift amount is 0), and when the program shift direction changes, the learning release number is set to 1. The number of learning releases is incremented each time the set release is performed and the release is performed again in the same program shift direction (or P shift amount is 0).

When the previous learning direction (program shift direction) is negative and the current program shift direction is positive, the program shift direction has changed from negative to positive, so the process proceeds to learning reset 1 processing to start new learning. , The learning release count is set to 1 and the learning previous direction bit is set to "10" (positive) to proceed to the learning store 2 process for updating only the learning release count and the learning previous direction bit (S5529, S5531, S5541). ). On the other hand, when the previous learning (program shift) direction is positive and the current program shift direction is negative, the program shift direction has changed from positive to negative, so proceed to learning reset 2 processing to start new learning. , The learning release number is set to 1, the learning previous direction bit is set to “01” (negative), and the process proceeds to the learning store 2 process (S5529, S5533, S5551).

[Learning Store 2 Process] The learning store 2 process is a process in which the learning release count and the previous learning direction bit are updated and saved, and the origin shift amount and the origin direction bit are not changed. That is, the learning release number and the learning previous direction bit are respectively stored in a predetermined bit of the RAM memory area (X) corresponding to the current program exposure mode (AE mode number X) (S5611, S5613). Then, the contents of the RAM memory area (X) regarding learning are written in the corresponding 2-byte memory area of the EEPROM 106, and then the process returns (S5615).

[Learning Up / Down Processing] Regarding the learning U / D processing in which the learning result is saved when the learning release number becomes equal to or larger than the change release number, that is, the origin shift is executed, the flowcharts shown in FIGS. This will be described with reference to the program diagram shown in 55C. When this learning U / D processing is entered, first the program shift direction is checked, and if the current program shift direction is positive (P shift direction bit is “0”), the learning up process is performed and the current program shift direction is checked. When the direction is negative (P shift direction bit is "1"), the learning down process is executed. When the program shift amount of the default program line or the learning program line is set to 0, a black circle 58f above the original point display mark (triangle mark) 58h lights up on the external display LCD panel 34. Note that the displays in FIGS. 85 to 90 are displayed when Ev (Lv) = 13.

[Learning Up Processing] In the learning up processing, first, the previous learning direction (program shift direction) is checked, and the previous learning direction is negative (learning previous direction bit is negative “10”), that is, the current program. When the shift direction has changed from the previous time, the origin shift amount and the origin direction bit are not updated, so the process proceeds to the learning reset 1 process (S5711). For example, in FIG. 55C, assuming that the current learning program line is, the previous program shift is −0.5, −1.0 Tv or less (or direction), and the current program shift is +0.5, +1. This is the case of 0.0 Tv or higher (or direction). For example, the previous time is the shift state shown in FIG. 90, and this time is the shift state shown in FIG. 86.

When the program shift direction is the same as the previous time, or when the program shift is not performed the previous time (shift amount is 0), 0 is entered in the learning release number and “01” is entered in the pre-learning direction bit. Then, the process proceeds to the origin shift amount setting and program shift amount setting steps of S5715 to S5727 (S5711, S5713). For example, if the current learning program line is, the previous program shift is 0, +0.5, + 1.5Tv or more (or direction), and the current program shift is + 0.5Tv or more (direction). Is the case. The default (learning) program line is displayed as shown in FIG. 86 when the program shift is +1.0 Tv.

Then, the origin shift amount is set according to the origin direction, that is, whether the learning program line is in the positive direction (including the case where they match) or in the negative direction with respect to the default program line. Addition / subtraction for 0.5 Tv is performed (S5715, S5717, S5719 or S5715, S5721).

When the learning program line is shifted in the positive direction relative to the default program line (that is, the origin bit is positive “0”) and the shift amount is less than 2, the original point shift amount is 0.5 Tv. The minutes are added (S5715 to S5719). Then, 0.5 Tv added to the origin shift amount is subtracted from the program shift amount, and the process proceeds to learning store 1 processing (S5727). In this embodiment, since the maximum value of the origin shift amount is limited to 2Tv, when the origin shift amount is 2Tv or more, the origin shift (shift of the learning program line) is not executed and the process from S5717 is started. Go to Learning Store 1. By the above-described up processing, for example, when the default program line is the learning program line and the program shift is +0.5 Tv (direction), the learning program line changes from to. When the default (learning) program line is added by + 0.5Tv from the state of FIG. 86 when the program shift is + 1.0Tv, the lighting of the black circle 58f changes as shown in FIG. 87, and the program line is +0. It shows that the program shift is +0.5 Tv instead of the learning program line shifted by 0.5 Tv. Further, when the program shift clear processing is performed, the program shift amount from the learning program line is cleared and displayed as shown in FIG. 88.

When the learning program line is shifted in the negative direction from the default program line, that is, when the origin bit is "1", the origin shift amount is reduced by 0.5 Tv (S5715, S5721). If the origin shift amount becomes 0, "0" is put in the origin direction bit, and if the origin shift amount does not become 0, the program shift amount is subtracted by 0.5Tv and the learning store 1 process is performed ( S5723, S5 725, S5727 or S5723, S5727). By the above process, for example, when the default program line is the current learning program line and the program shift is +0.5, +1.0, + 1.5Tv or more (,, direction), The new learning program line changes to.

[Learning Down Processing] The learning down processing is started when the program shift direction is negative (P shift direction bit is “1”) in step S5701. In the learning down process, first, whether or not the program shift direction has changed from the previous time is checked by the previous learning direction bit. If the program shift direction has changed from the previous time (the previous learning direction bit is “01”), the learning reset process 2 Then, the learning content is not updated (S5731). If the program shift direction has not changed from the previous one (the previous learning direction bit is "10"), the learning release number is set to 0 and a negative "01" is put in the learning previous direction bit (S5733).

Then, the origin shift amount is added or subtracted according to the origin direction, that is, whether the learning program line is in the negative direction or the same or positive direction as compared with the default program line (S5735, S5737 or S5735, S5743, S5745).

When the origin direction is positive, the origin shift amount is subtracted by 0.5 Tv (S5735, S5737). Here, the origin shift amount after subtraction may be less than 0 (-0.5 Tv), so check whether the origin shift amount has become less than 0. If it is less than 0, perform absolute value processing of the origin shift amount. Then, the origin direction bit is changed to “1” (negative) and the process proceeds to S5747. If the origin shift amount after subtraction is 0 or more, the process proceeds to S5747 (S5739, S5741). By the above down processing, for example, when the default program line is the learning program line and the program shift is -0.5, -1.0, -1.5 Tv or below (,, direction), The learning program line becomes. The display when the learning program line is and the program shift is -1.5 Tv is shown in FIG. 89, and the display mode when the learning program line becomes as shown in FIG. 90 is shown in FIG. .

When the origin direction is negative, the origin shift amount may exceed the limit value (2Tv), so it is checked whether it is equal to or more than the limit value. If it is less than the limit value (2Tv), the origin shift amount is 0. .5 Tv is added, 0.5 Tv is subtracted from the program shift amount, the process proceeds to S5749, and if it is equal to or more than the limit value, the process jumps to S5749 (S5735, S5743 to S5747, S5749 or S5735, S5743, S5749). By the down processing described above, for example, when the default program line is the learning program line and the program shift is −0.5 Tv or less (direction), a new learning program line becomes.

Since the program shift amount subtracted in S5747 may become 0, when it becomes 0, the P shift direction bit is changed to “0” (positive) and the program proceeds to learning store 1 and the program shift is performed. When the amount is not 0, the process directly proceeds to learning store 1 (S5749, S5751).

[Learning Stores 1 and 2] Next, the learning store 1 processing for storing the learning status in the EEPROM 106 will be described with reference to FIG. First, the original point shift amount and the origin direction bit set by the learning up / down processing are stored in predetermined bits of the RAM memory areas STDYCNT (X) and GENPSFT (X) corresponding to the current program exposure mode, and then learned. The process proceeds to store 2 processing (S5601, S5603).

In the learning store 2 process, the learning release number and the learning previous direction bit are further stored in a predetermined bit of the RAM area (X) corresponding to the current program exposure mode (S5611, S5613). Then, the contents of the RAM memory areas STDYCNT (X) and GENPSFT (X) relating to learning are written in the corresponding 2-byte memory areas STDYCNT (X) and GENPSFT (X) of the EEPROM 106, and then the process returns (S5615).

As described above, according to the single-lens reflex camera equipped with the learning function of the present invention, the photographer selects the person exposure mode, landscape mode, moving object mode or proximity mode as the program exposure mode and selects the learning mode. When the program is released in the positive or negative direction a predetermined number of times and the program line is shifted in the direction of the shift by 0.5 Tv step (moving the origin), the shifted learning program line is moved after the shift. The shutter speed and aperture value are set as a reference, and program shift and learning are performed. In other words, in the single-lens reflex camera of this embodiment, when the photographer shifts the program and releases, the shift tendency is learned for each release, and the learning result is updated (saved) after learning for a predetermined number of times. The shutter speed and aperture value are set based on the learning result, and new learning is performed.

As described above, in the description of the present embodiment, the combination of the program shift amount and the learning change number is selected, but the combination is not limited to this, and the shift amount and the learning change number can be selected separately. The learning frequency may be changed in two steps with a predetermined shift amount as a boundary, but it is also possible to change the learning frequency in three steps or more or in accordance with the shift amount.

Further, although learning is changed in 0.5 Tv step units in the present embodiment, it is not limited to this value. For example, it may be 1.0 Tv step or 0.3 Tv step, or may be configured to skip to a specific Tv value. Further, in the present embodiment, the shutter speed Tv is prioritized to execute the program process, the program shift process, and the learning and storing process, but the aperture value Av may be prioritized to execute each of the above processes. .
