Abstract

PURPOSE:To prevent unexpected photographing due to a failure to return the mode to improve the convenience for use of a camera by obtaining the standard mode set time based on the photographing interval time and forcibly setting the standard mode at the time of elapse of this standard mode set time after preceding photographing. CONSTITUTION:A storage means 504 obtains the photographing interval time from preceding photographing to current photographing in accordance with the time counted result of a time counting means 503 and stores it at each time of photographing. A calculating means 505 calculates the standard mode set time by the stored photographing interval time; and when the standard mode set time elapses after photographing, a setting means 502 sets the prescribed standard mode independently of the operation of an operating means 501. Consequently, though photographing is performed in the mode other than the standard mode, the standard mode is automatically set when the standard mode set time elapses. Thus, unexpected photographing is prevented when the mode changing operation is forgotten, and the convenience for use of the camera is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a mode setting device for a camera that selects and sets one of a plurality of modes.

B. Conventional technology For example, in a camera equipped with an imprint device that imprints data such as the date on the film, the data imprint mode includes, for example, a year/month 8 mode that imprints the date and time of the photograph; It has a date/time/minute mode for capturing images, a film count value mode for capturing film count values, etc., and either mode can be selected and set by operating an operating member.

Further, as control modes in which a plurality of modes can be set as described above, in addition to the data capture mode described above, there are an exposure control mode, a photometry mode, a focus adjustment mode, and the like.

C0 Problems to be Solved by the Invention However, in conventional cameras, the mode set to -degree is maintained until the next mode change operation is performed. Therefore, if you happened to set a mode different from the mode you normally use (standard mode) when you used the camera last time, you will not have to change the mode the next time you use the camera to return to standard mode. This operation is troublesome, and if the user forgets to change the mode, there is a risk that an undesirable photograph will be taken.

A technical problem of the present invention is to set the standard mode the next time the camera is used, even if a photograph is taken in a mode other than the standard mode.

08 Means for Solving the Problems This will be explained with reference to FIGS. 1(a) and 1(b), which are diagrams corresponding to claims. Operation means 5
01 and a setting means 502 that selects and sets one of the modes according to the operation of the operation means 501.

The invention of claim 1 provides, as shown in FIG. 1(a),
A clocking means 503 that starts timing when a photograph is taken; a storage means 504 that calculates and stores the photographing interval time from the previous photograph to the relevant photograph every time a photograph is taken from the time measurement result of the clock means 503; The above technical problem is solved by configuring the setting means 502 as follows, including a calculation means 505 for calculating the standard mode setting time from the interval time.

In other words, the setting means 502 controls the operating means 501 when the standard mode setting time has elapsed from the point in time when photographing was performed.
A predetermined standard mode is set regardless of whether or not the operation is performed.

Further, the invention according to claim 2 is provided with a detection means 601 for detecting that the film is taken out from the camera, as shown in FIG. 1(b), and the setting means 502 is configured as follows. .

That is, when it is detected that the film has been removed,
Setting the predetermined standard mode regardless of whether or not the operating means 501 is operated 3 E0 effect (1) When the invention photography of claim 1 is performed, the storage means 504 stores information from the previous photography to the relevant photography. Timing means 503 for measuring the shooting interval time
Calculate and store from the timing results.

The calculating means 505 calculates the standard mode setting time from the stored photographing interval time, and the setting means 502 calculates the standard mode setting time from the time when photographing is performed.
A predetermined standard mode is set regardless of whether or not the operating means 501 is operated. Here, the standard mode is a mode that is considered to be the most commonly used among multiple modes. For example, it may be predetermined on the camera side, or it may be determined from the number of times the mode has been used in the past. .

According to the above configuration, even when photographing is performed in a mode other than the S semi-mode, the standard mode is automatically set when the standard mode setting time has elapsed.

This standard mode setting time is determined by how often the photographer takes pictures.

(2) When the detection means 60↓ detects that the invention film of claim 2 is taken out, the setting means 502 sets the predetermined standard mode regardless of whether or not the operation means 501 is operated. . That is, when the film is removed, it is determined that the camera will not be used for a long time after that, and the camera is forced into the standard mode.

When the cartridge is loaded into the camera body 100, the cartridge detection switch 107 is turned on and the input port Ill becomes low level.
01 outputs a patrone signal by setting the output port OL8 to a low level. As a result, the transistor 123 turns on and the input port of the microcomputer 201 ■2□
becomes low level. Therefore, the microcomputer 201 can detect that a cartridge, that is, a film is loaded in the camera body 100, when the input port I2□ becomes low level.

Furthermore, the microcomputer 101 sets the output port 042 to a high level upon completion of photographing.

As a result, the transistor 127 is turned on and the input port rz3 of the microcomputer 201 becomes low level. Here, the output port ○ of the microcomputer 101
.

Next, the control procedure of the microcomputers 101 and 201 will be explained with reference to the flowcharts of FIGS. 3 and 4.

FIG. 3 shows the control procedure of the microcomputer 01 of the camera body 100. When the battery 103 is loaded into the camera body 100, this program is started, and first, in step 5101, it is determined whether a cartridge is loaded or not based on whether the input port I, 1 is at a high level or a low level. If input port I is at low level,
Since the switch 107 is on, it is determined that the cartridge is loaded, and the process proceeds to step 5102, where the output port oi1 is set to high level, that is, the cartridge cooling signal is output, and the process proceeds to step 5104.The output of this cartridge signal causes the transistor 123 to be activated. is turned on and the data 4 inclusion device 20
Input port I of the microcomputer 201 on the 0 side, □
becomes low level.

On the other hand, if the input port I is at a high level in step 5101, it is determined that the switch 107 is off, that is, the cartridge is not loaded, and the process proceeds to step 5103, where the output port 01 is set to a low level, i.e. The output of the patrone Shin-Chin is stopped and the process advances to step 5104. This turns off the transistor 123, and the input port □□2 of the microcomputer 201 becomes high level.

In step 8104, it is determined whether the main switch 111 is on or not depending on whether the input port 11□ is at low level or high level, and if the input port 11□ is at high level, it is determined that the main switch 111 is off and step 51
The process returns to 01 and the above process is repeated. At this time, even if the release button is operated, no photography is performed.

If it is determined in step 5104 that the input port Lx is at a low level, it is determined that the main switch 111 is on, and the process proceeds to step 5 (05).
It is determined whether the release switch 115 is on or off based on the state of the switch 3. If the input port Iia is at a high level, it is determined that the release switch 115 is off, and the process proceeds to step 5.
Returning to lot, if the input port E□ is at a low level, it is determined that the release switch 115 is on, and the process proceeds to step 5.
The process advances to step 106 and photography is performed. That is, an exposure value is calculated from information such as subject brightness and film sensitivity input from a photometer or film sensitivity setting device (not shown), and the aperture and shutter are driven via the exposure control circuit 119 based on this exposure value. Then expose the film.

Thereafter, in step 5107, output port 0.2 is set to high level for a predetermined period of time. That is, the imaging signal is output for a predetermined period of time. As a result, the transistor 127 is turned on for a predetermined period of time, and the input port 11m of the microcomputer 201 on the side of the data 4-input device fi200 is brought to a low level for a predetermined period of time.

Here, this predetermined time is the sensitivity of the loaded film (
(read from the DX code of the patrone via a mechanism not shown).

Next, in step 8108, the film winding device 121
The film is wound up by one frame, and the process returns to step 8101, where the above-described process is repeated.

Next, according to FIG. 4, the data 4-incorporating device i! The procedure of processing by the microcomputer 201 on the 1200 side will be explained.

When the battery 203 is loaded into the data 4 loading device 200, this program is started and first performs an initial reset in step 5201, which includes setting a predetermined standard setting mode (here, the year/month H mode), The clock and calendar are set to their initial state, and various parameters and count values are set to their initial values. That is, the exposure setting parameter m is set to "O", the time t1 and t2 are set to "O", the average shooting interval time T is set to "O", the count value n of the cumulative number of shots is set to rOJ, and the film count value N is set to "IJ, cumulative Let the photographing interval time Tx be rOJ.Here, the photographing setting parameter m indicates the photographing state; when m is rOJ, the photographing state is canceled, and when m is "1", the photographing state is set. ing.

Next, in step 3202, time measurement of time t is started in order to perform clock processing and calendar processing, and step 520
In Step 3, well-known clock processing is performed to determine 1 second, 60 seconds, and 60 minutes based on the measured time t1, count up seconds 2 minutes 9 o'clock, and reset to zero, and step 5204
Then, depending on whether the clock time started in step 5202 is 24 hours or not, the day, February, 1 year is counted up, or "1" is counted.
Perform the well-known calendar process to reset the calendar.

Next, the process proceeds to step 5205, where the mode change device 5120
The output of step 7 is read to determine whether a mode change operation has been performed. If step 5205 is negative, the process proceeds to step 5206; if affirmative, mode change processing is performed in step 5209, and the process proceeds to step 5217.The mode change process means, for example, that the date mode is set according to the mode change operation. If the mode has been set, the process changes and sets the date, hour, and minute mode.

In step 8206, the output of the numerical value correction device 209 is read and it is determined whether or not a numerical value correction operation has been performed.
Proceed to step 7. What is numerical value correction processing?1For example, if the date, hour, and minute mode is set, the numerical value correction device! This is a process of changing and setting the time according to the operation at step 209.

In step 5207, it is determined whether the photo capture switch 211 is on or not depending on whether the input port ■2□ is at a low level or high level, and when the input port ■2□ is at a low level, the switch 211 is on, that is, when the input port ■2□ is at a low level. It is determined that the imprint switching operation has been performed, and the process proceeds to step 5211. In step 5211, it is determined whether the imprint parameter m is "0".

When the background is determined, m is set to 1 in step 5212, and then, in step 5213, processing is performed to obtain the above-mentioned reflected state, and the process proceeds to step 5217.

On the other hand, if step S211 is negative, m=o is set in step 5214, and then the projection state is canceled in step 5215, and the process proceeds to step 5217.

Also, in step 3207, input port I is input. If is at a high level, it is determined that the switch 211 is off, that is, no photo switching is being performed, and the process advances to step 8208.

t * (T + t.

Determine whether or not. Here, t and ii are the time measured since the previous input of the photographing signal, that is, the elapsed time since the previous photographing (shirt release), as will be described later, and time measurement is started in step 5232, which will be described later. Further, T is the average photographing interval time (determined in step 8228 described later), to is a time of, for example, several minutes, and T+t corresponds to the standard mode setting time. If step 8208 is affirmative, it is determined that the elapsed time L2 since the previous shooting has not reached the standard mode setting time, and step 521
If step 8208 is negative, it is determined that the elapsed time t has reached the standard mode setting time, and step 8216 sets the above-mentioned standard mode, ie, date mode, and the process advances to step 5217. Note that this standard mode is not limited to the 1 year/month yen mode.

In step 5217, a display signal is output to the drive circuit 219 to display the set mode, its numerical value, and whether or not it is an imprint setting on the external display device 221, and the imprint liquid crystal 223 is set to the same value. .

Next, in step 8218, it is determined whether a cartridge, that is, film is loaded in the camera body 100, and if the input port □ is at a high level, it is determined that no film is loaded, and the process proceeds to step 5219. 5219, the film count value N is rl
J is reset and the process proceeds to step 5220, where it is determined whether the cumulative number of photographing times n is rOJ. If m=o, that is, if no photographing has been performed after starting this program, the process returns to step 5203.

If n≠O, that is, if imaging has been performed at least once, the timer t2 is stopped in step 5221, and the time t2 is reset to zero in step 5222, and the process returns to step 5203.

Meanwhile, in step 8218, input port I is input. If it is determined that the film is at the low level, it is determined that the film is loaded, and the process proceeds to step 5223, where the imaging signal is input from the camera body 100 side depending on whether the input port □ is at the low level or the high level. Determine whether or not. This imaging signal is output immediately after photographing, as described above. Input port I. If the input port 23 is at a high level, it is determined that no imaging signal is input and the process returns to step 5203. If the input port 23 is at a low level, it is determined that the imaging signal has been input and the process proceeds to step 5224.

In step 5224, it is determined whether the cumulative number of shots n is rQJ. If n = Q, the process proceeds to step 5229. If n≠0, in step 5225, it is determined whether the film count value N is "1" or not. Determine whether or not. If N=1, proceed to step 5229; if N≠1, proceed to step 8226.

In step 8226, the time measurement of time t2 is stopped, and then in step 5227, the cumulative shooting interval time TX is changed to the time t2.
is added and set as a new cumulative photographing interval time T1, and the process proceeds to step 8228. This cumulative photographing interval time T□ is divided by the cumulative number of photographing times n to calculate the average photographing interval time #JT, and the process advances to step 5229.

Here, the first photograph after loading the power battery (step 5)
224), it is not possible to calculate this average imaging interval time T, so step 82
Skip 26-8228. Further, since the average photographing interval time T cannot be calculated even in the first photographing after loading the film (when it is determined that N=1 in step 5225), steps 8226 to 8228 are skipped.

In step 5229, the imprint setting parameter m is “1”.
”, and if m=1, that is, in the photographic state, in step 5230, the output port 02□ is set at a high level for a predetermined period of time, that is, a light emission signal is output, and the process proceeds to step 5231.

This light emission signal turns on the transistor 227, lights up the lamp 225, and the lamp light transmitted through the imprinting liquid crystal 223 causes data to be imprinted onto the film.

Here, the predetermined time is the time during which the capture signal is input from the camera body, that is, the time depending on the film sensitivity as described above. In other words, the time required to capture data varies depending on the film's sensitivity, and a high-sensitivity film requires less time than a low-sensitivity film. Therefore, here, the exposure time is changed depending on the sensitivity of the loaded film. In this example,
This exposure time is adjusted on the camera body 100 side, but it may also be adjusted on the exposure device 200 side.In this case, the exposure time is adjusted on the camera body 100 side. The output time may be at least the time during which the microcomputer 201 can determine the input, and does not need to be the time equivalent to the imaging time.

In step 8231, time L2 is reset to zero, and in step 5232, time rJtz is started to be counted, and the process proceeds to step 5233. In step 5233, the cumulative number of shots n and the film count value N are each incremented by rlJ, and the process returns to step 5203.

According to the above procedure, timing is started every time a photo is taken, and when the next photo is taken, the time between shots is cumulatively stored, and this cumulatively stored time is divided by the number of shots n. Thus, the average photographing interval time T is calculated. Then, when the average shooting interval time T plus a time t0 of several minutes has passed since the shooting (standard mode setting time), the standard mode (in this case, the date mode) is set, regardless of whether or not there is a mode change operation. is set.

In other words, if you set the 8-hour mode from the date mode to the 8-hour mode by operating the operating member constituting the mode change bag [207] and take a picture in this mode, when the standard mode setting time has elapsed since the picture was taken, the automatic automatically returns to date mode.

This average photographing interval time varies depending on the photographer; for example, it becomes shorter when photographing is performed multiple times in a short period of time, and becomes longer when photographing is performed infrequently.

Therefore, according to the above, if you happen to take a picture in a mode other than standard mode, and then do not use the camera, there is a high possibility that standard mode will be set the next time you take a picture, and it will return to standard mode. This eliminates the need to perform troublesome operations, and prevents undesirable photographs from being taken due to forgetting to perform such operations.

In the configuration of the above embodiment, the mode changing device 207 serves as the operating means 501, and the microcomputer 201 serves as the setting means 502. A clock means 503 constitutes a storage means 504 and an arithmetic means 505, respectively.

Furthermore, in the above description, the standard mode setting time is set as the average photographing interval time T plus the predetermined time.

If steps 5227 and 8228 in FIG. 4 are replaced with steps 8241 to 244 in FIG. 5, the most frequent imaging interval time will be used instead of the average imaging interval time.

That is, after stopping the time measurement of time t2 in step 8226 of FIG. 4, the process proceeds to step 5241, and it is determined in which of several pre-divided time ranges this time (shooting interval time) tz is included. Here, this time range is, for example, less than 1 minute, 1 minute or more and less than 2 minutes, 2 minutes or more and less than 3 minutes.
Less than a minute, ..., it may be equally spaced such as 60 minutes or more, or less than 10 seconds, 10 seconds or more and less than 30 seconds, 30 seconds or more and less than 1 minute, 1 minute or more and less than 2 minutes, 2 minutes or more and 4 minutes. less than,··
They do not have to be equally spaced like ・.

Next, in step 5242, the count value corresponding to the time range determined in step 5241 is incremented by "1", and in step 5243, the one with the largest count value among each time range is set as the most frequent time range. Thereafter, in step 5244, any time included in the most frequent time range is set as the most frequent imaging interval time T, and the process proceeds to step 5229 in FIG.

According to the above, after shooting at a certain point, the standard mode is set when a time equal to the most frequent shooting interval time T plus a time t0 of about several minutes has elapsed, and the same effect as described above can also be obtained by this. . Furthermore, when using f&frequent imaging interval time, the influence of extremely long imaging interval time or extremely short imaging interval time is less likely to appear than when using average imaging interval time.

Furthermore, although the example above has been shown in which the standard mode is set in advance in the camera, the mode most frequently used by the photographer may be used as the standard mode, as shown in FIG. 6, for example.

That is, in FIG. 6, when the battery 203 is loaded into the data imprinting device 200, an initial reset is first performed in step 5251. This is in addition to the contents of step 5201 in FIG. 4 described above.

This resets the count value of the set number of times provided corresponding to each mode to zero.

Next, in step 5202, after starting the time measurement of time 〇, the processes of steps 3203 to 52L5 in FIG. 4 are performed,
Then in step 5208 as described above.

Determine whether or not t Then, in step 5255, the mode with the highest number of settings is set as the most frequently set mode (standard mode), and the process returns to step 5203.

Further, if step 8208 is negative, that is, if the elapsed time t2 since the previous imaging exceeds the time T (average imaging interval time or most frequent imaging interval time) plus the predetermined time t0, step 5252 Then, it is determined whether n≠O.

If n#o, the process proceeds to step 5253, sets the above-mentioned most frequent setting mode, and proceeds to step 5217. If n=0 is determined in step 5252, step 5253 is skipped and the process proceeds to step 5217.

According to the above, the mode that the photographer uses most frequently while the camera is not in use is set as the standard mode, so the standard mode predetermined within the camera is Compared to the case where settings are made, it is possible to more closely match the photographer's intentions.

Second Embodiment Next, a second embodiment of the present invention will be described with reference to FIGS. 7 and 8.

In the first embodiment, an example was shown in which the standard mode is set when the average shooting time or the most frequent shooting time plus a few minutes (a semi-mode setting time) has elapsed since the previous shooting. In this embodiment, the standard mode is set when the cartridge (film) is taken out from the camera body 100.

FIG. 7 shows the control procedure of the microcomputer 201 on the data imprinting device 200 side, in which the battery 2.
This program is started when the 03 is loaded. First, in step 8301, an initial reset is performed. The contents include setting a predetermined standard mode, setting the clock and calendar to the initial state, and setting the above-mentioned photography parameter m to "
O'', and rOJ is the clock time for performing clock processing and calendar processing.

Next, the process proceeds to step 5302 to start time measurement, and in step 5303, it is determined whether a cartridge is loaded based on the state of the input port I22. step 530
If 3 is denied, the process proceeds to step 5311, and step 5
Data processing is performed in step 311, display processing is performed in step 5312, and the process returns to step 5303. The content of the data processing is the subroutine (steps 8401 to 5412) shown in FIG.
), and step 820 in FIG. 4 described above.
3 to 5215, detailed explanation will be omitted here. Further, step 5312 is a process of displaying the set mode, the numerical value in that mode, whether or not it is a photo setting, and so on.

If step 5303 is affirmed, step 5304 performs the data processing shown in FIG. 8, and step 530
In step 5, display processing similar to step 5312 described above is performed, and the process proceeds to step 8306. In step 5306, it is determined whether or not an image signal has been input, and the input port Ll
If the input port I2m is at a low level, it is determined that an imprint signal has been input, and the process proceeds to step 5307. If the input port I2m is at a high level, it is determined that an imprint signal has not been input, and the process proceeds to step 5309.

In step 8307, the imprint setting parameter m is “1”.
”, and if m≠1, proceed to step 3309; if m=1, output a light emission signal in step 8308 and proceed to step 5309. To output a 0 light emission signal, output port 02X is set to a predetermined value. This is done by keeping the level high for hours.

This turns on the transistor 227 and causes the lamp 225 to turn on.
lights up and data is imprinted.

In step 5309, it is determined again whether a cartridge, that is, a film is loaded, and if it is determined, the process returns to step 5304 and the above-described process is repeated, and if it is negative, the process advances to step 5310. Here, step 530
If step 5309 is negative after step 3 is affirmed, it means that the cartridge was removed after the image was captured in step 8308, and in this case, step 8310 changes the date mode, which is the standard mode. After setting, the process returns to step 5303. It goes without saying that the standard mode is not limited to the date mode.

According to the above procedure, when the cartridge, that is, the film is removed from the camera body 100, it is determined that the camera will not be used for a long time, and the standard mode is set. Therefore, the same effects as in the first embodiment can be obtained.

In the above embodiment, the cartridge detection switch 107 constitutes the detection means 601.

FIG. 9 shows a modification, in which the standard mode is set to the most frequent setting mode.

That is, first, an initial reset is performed in step 3350, which includes, in addition to the content explained in step 5301 of FIG. Steps 8302 and 303 to 305 are performed, and if step 5306 is affirmed, in step 835L,
The count value of the set number of times corresponding to the set hair mode is set to 1.
At the same time as counting up by 1, step 535
2, the most frequent setting mode is determined as described above. after that,
Steps 5307 and 308 are performed, and step 53
If 09 is negative, the most frequent setting mode is set in step 5353 and the process returns to step 5303.

According to the above, when the film is taken out, the most frequent setting mode is set.

In the above first and second embodiments, the data capture mode has been described, but the mode is not limited to this, and for example, exposure control mode (program mode, shutter priority mode, aperture priority mode, manual mode, etc.), Focus adjustment mode (automatic focus adjustment mode, manual focus adjustment mode), film winding mode (1-frame winding mode, continuous winding mode, etc.), photometry mode (center-weighted metering mode, spot metering mode, multi-segment metering mode, etc.) ), or other control modes in which multiple modes can be set.

Effects of the G9 Invention According to the invention of claim 1, the standard mode setting time (for example, the average shooting interval time or the most frequent shooting interval time) is calculated based on the shooting interval time, and the standard mode setting time is calculated based on the shooting interval time, and the standard mode setting time is calculated based on the shooting interval time. Now, if you happen to take a picture in a mode other than standard mode and you no longer use the camera, the standard mode will be set. Therefore, whether the photographer takes pictures frequently or infrequently, there is a high possibility that the next time the camera is used, the 4M semi-mode will be set, and there will be no need to change it to the standard mode. ,
In addition, it is possible to prevent undesired photographs from being taken due to forgetting to reset the mode, thereby improving the usability of the camera.

Further, according to the invention of claim 2, when the film is removed from the camera, the standard mode is forcibly set, so after taking a picture in a mode other than the standard mode and removing the film, the camera is stopped from being used. In this case, the standard mode is set, and the same effect as described above can be obtained.
