Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera capable of selecting a plurality of photographing modes.

[0002]

2. Description of the Related Art In a camera, a shutter priority mode is used as an exposure mode for determining a combination of shutter speed and aperture value.
Aperture priority mode, program mode, manual mode, etc. are known, but in recent years, in addition to these normal exposure modes, special exposure modes adapted to the shooting conditions have come to be used.

For example, when an exposure mode called a portrait mode is used for photographing a person, the optimum combination of shutter speed and aperture value is set for portrait photographing. In addition to portrait mode, there are landscape mode suitable for shooting landscapes and close-up mode suitable for close-up photography, each set to obtain the optimum effect in its own situation. Has been done.

If these special exposure modes are added to conventional camera setting devices, the number of exposure mode setting items increases, and it takes time to set a desired exposure mode. In order to solve such a problem
There is known a setting device in which the exposure mode is divided into two groups, a normal exposure mode and a special exposure mode, in order to perform the setting as shown by -67250, and the setting is made easier.

[0005]

However, since the exposure mode is divided into two or more groups so that the desired exposure mode can be easily reached, the switching is speeded, but in the case of an incorrect operation. Has the drawback of losing its previous settings. For example, in the case of a camera whose exposure-related compensation settings, metering mode, and sync mode settings are set to specific values when the special exposure mode is called, the settings are saved in the normal exposure mode group, but When entering the exposure mode setting, the settings in the normal exposure mode group are changed, and it becomes necessary to redo the setting.

Further, in the conventional camera, when the special exposure mode is set by mistake, another setting member for setting the normal exposure mode must be operated again when returning to the normal exposure mode. I sometimes felt inconvenient. An object of the present invention is to provide a camera capable of promptly selecting an appropriate mode without feeling annoyance even when the other group mode is entered as described above.

[0007]

In order to achieve the above object, in the invention according to claim 1, a plurality of photographing modes divided into a first group and a second group, the first group and the first group are provided. Two
A switching unit for selectively switching between the groups, a first selection unit for selecting one of the first group shooting modes, and a second selection unit for selecting one of the second group shooting modes. In the camera, the second selection means can select the shooting mode of the second group and also select the shooting mode of the first group that was selected immediately before being switched by the switching unit. .

According to a second aspect of the invention, in the camera according to the first aspect, the photographing mode is an exposure mode. According to a third aspect of the present invention, the storage unit has a storage unit that stores a set value in the first group that was set immediately before the switching from the first group to the second group by the switching unit. The setting value is set when the photographing mode of the first group is selected by the selecting unit.

[0009]

In the present invention, the second selecting means for selecting the photographing mode of the second group can be switched by the switching section for switching the first group and the second group while selecting the photographing mode of the second group. Since the photographing mode of the first group that has been selected immediately before is selected, even if the photographing mode of the second group is switched to the selectable state of the second group, the second selection unit immediately before switching is selected. One group of shooting modes can be selected.

According to the third aspect of the invention, the set value set in the first group immediately before switching from the first group to the second group is stored, and the photographing mode of the first group is set by the second selecting means. When it is selected, it is set to the set value, so
There is no need to set it again.

FIG. 2 is a diagram showing the relationship between the exposure mode grouping and the contents of the RAM defining each mode.

Here, the exposure control mode and its setting in this embodiment will be described with reference to FIG. In the present embodiment, there are four types of normal exposure programs: program mode, shutter priority mode, aperture priority mode, and manual mode. And special exposure modes such as portrait mode, landscape mode, commemorative photo shooting mode, close-up mode,
There are eight types: sports mode, silhouette mode, night view mode, and dynamic mode. In a special exposure mode, the shutter seconds are suitable for shooting individual portraits, landscapes, commemorative photos, close-ups, shooting with movement such as sports, silhouette-like shooting, night view shooting, panning, etc. A program diagram for giving a combination of time and aperture value is provided, and an exposure correction value and a flash light emitting device control mode suitable for each are prepared in advance. The above-mentioned 12 kinds of exposure modes are independent modes, and two or more kinds of modes are not set at one time.

In the present embodiment, as shown in FIG. 2, 12 kinds of exposure modes are grouped into 4 kinds of normal exposure modes and 8 kinds of special exposure modes. The four types of exposure modes were the first exposure mode group, and the eight types of special exposure modes were the second exposure mode group. The determination of the mode is performed by M0, M1 and M2 which are RAMs in the MCU1. M0 is the first
For identifying the exposure mode group and the second exposure mode group, when M0 = 0 indicates that one of the first exposure mode groups is set, and when M0 = 1, It indicates that any one of the second exposure mode group is set.

M1 indicates which of the first exposure mode groups is set when M0 = 0. When M1 = 0, the program mode is set, when M1 = 1, the shutter priority mode is set, and M1 = A value of 2 indicates that the aperture priority mode is set, and a value of M1 = 3 indicates that the manual mode is set. M2 indicates which of the second exposure mode groups is set when M0 = 1. When M2 = 0, portrait mode, when M2 = 1, landscape mode, when M2 = 2. Is a souvenir photo mode, M2 = 3 is a close-up mode, M2

A value of 8 indicates that the user has selected to return from the special exposure mode to the normal exposure mode. Return Normal exposure mode is M
Determined by a value of 1.

Next, the procedure of mode setting by the MCU 1 will be described with reference to the flowcharts of FIGS. This control is periodically activated in the MCU 1, and first, in step # 1 of FIG. 3, the state of SW3 is determined. SW3 is pressed and O
If it is N, the process proceeds to step # 2, and if SW3 is not pressed, it is OFF, so the process proceeds to step # 14 in FIG.

In step # 14 of FIG. 4, the state of SW4 is discriminated, and if SW4 is pushed and turned on, the process proceeds to step # 15. If SW4 is not pressed, it is OFF, and the process proceeds to step # 29 in FIG. Step # 2 of FIG.
At 9, the rising edge of SW4 from ON to OFF is determined, and if the rising edge is determined, the process proceeds to step # 30. If the rising edge of SW4 is not determined in step # 29, the process returns.

In step # 30, it is determined whether or not M0 = 1. If M0 = 1, the process proceeds to step # 31.
When M0 = 1 is not satisfied, the process returns. Step #
In 31, a specific value is set for the special exposure mode, such as exposure correction and flash light emitting device control mode. on the other hand,
When it is determined that SW3 is ON in step # 1 of FIG. 3, the process proceeds to step # 2.

In step # 2, if M0 is 0, the process proceeds to step # 6, and if M0 is not 0, the process proceeds to step # 3. SW1 or SW in steps # 3 and # 4
If the trailing edge of 2 is discriminated, and if the trailing edge is discriminated, M0 is set to 0 and the routine returns. If the trailing edge cannot be discriminated, the routine directly returns.

In step # 6, the fall of SW1 is discriminated. If the fall is discriminated, the process proceeds to step # 7. In step # 7, if M1 is 3 or more, step # 7.
9. If M1 is less than 3, proceed to step # 8. In step # 8, 1 is added to M1, and in step # 9, M1 is set to 0. When the fall of SW1 is not determined in step # 6, the process proceeds to step # 10, and step # 10
At 10, the trailing edge of SW2 is determined.

If the trailing edge of SW2 is determined in step # 10, the process proceeds to step # 11. If the trailing edge of SW2 is not identified, the process returns. Step # 1
If 1 and M1 is 0 or less, proceed to step # 13 to set M1
If is 1 or more, the process proceeds to step # 12. Step # 1
In step 2, subtract 1 from M1, and in step # 13, add 3 to M1.
Is set.

On the other hand, at step # 14 in FIG.
If N, proceed to step # 15. Step # 15
If M0 = 1, then go to step # 19, where M0
If = 1 is not satisfied, the process proceeds to step # 16. In steps # 16 and # 17, the fall of SW1 or SW2 is determined, and when the fall of either SW1 or SW2 is determined, M0 is set to 1.

In step # 19, the fall of SW1 is determined. If the fall is determined, the process proceeds to step # 20, and if the fall is not determined, the step # 2 is performed.
Go to 3. In step # 23, the fall of SW2 is determined, and if the fall of SW2 is determined, step # 23
If the determination is not made, the procedure returns to step 24.

When the fall of SW1 is detected in step # 19, the process proceeds to step # 20. In step # 20, if M2 is 8 or more, the process proceeds to step # 21, and if M2 is less than 8, the process proceeds to step # 22. In step # 21, 1 is added to M2, and in step # 22, M2 is set to 0.

If it is determined in step # 23 that the SW2 has fallen, the process proceeds to step # 24. If M2 is 0 or less, the process proceeds to step # 26, and M2 is set to 8. If M2 is 1 or more, the step is performed. Proceeding to # 25, 1 is added to M2. In step # 27, when M2 = 8, M0 is set to 0 and the process returns. If M2 = 8 is not satisfied, the process directly returns.

According to the above procedure, when one of the exposure mode groups is selected by SW3 or SW4, the setting of the other exposure mode group is canceled, and the exposure mode group selected by SW1 and SW2 is changed. Be seen. Moreover, it is possible to return to the normal exposure mode setting while the special exposure mode group is being set by SW2. A detailed description including display control will be given below.

FIG. 6 shows a normal exposure mode selection switch SW3.
FIG. 6 is a diagram showing a change in display when is operated. When the normal exposure mode selection switch is turned on while any one of the second exposure mode groups is set, the first exposure mode group is selected and the display of FIG. 6A is performed. Since the second exposure mode group has not yet been switched at this point, the display section 4 displays "Ps".

When the up switch SW1 or the down switch SW2 is operated in this state, M0 becomes 0, so that the normal exposure mode stored in M1 is set.
That is, if M1 = 0, the program mode is set and the display unit 4 becomes "P" as shown in FIG. 6 (b). M1 =
If it is 1, the shutter priority mode is set, and FIG.
The display section 4 becomes "S" as shown in FIG. If M1 = 2, the aperture priority mode is set and the display unit 4 displays “” as shown in FIG.
If M1 = 3, the manual mode is set and the display unit 4 becomes "M" as shown in FIG. 6 (e).

As described above, in this embodiment, since the first and second groups of independent RAMs M1 and M2 are used, when the first exposure mode group is switched to the second exposure mode group. However, the previously set normal exposure mode can be stored, and the previously set normal exposure mode can be reset when the first exposure mode group is selected again.

After that, when the up switch SW1 is further turned on, the count of M1 is performed at each fall, and the mode and its display are switched in the direction of the broken line arrow in FIG. 4 accordingly. In other words, by incrementing M1 from 0 to 1, the program mode of FIG.
From "P" display to "S" in shutter priority mode of FIG. 6 (c)
The display changes.

Further, by incrementing M1 from 1 to 2, the display changes from "S" in the shutter priority mode of FIG. 6C to "A" in the aperture priority mode of FIG. 6D. M1
By counting up from 2 to 3, the display changes from "A" in the aperture priority mode of FIG. 6D to "M" in the manual mode of FIG. 6E. Then, by counting up M1 from 3 to 0, the "M" display in the manual mode in FIG. 6 (e) changes to the "M" in the program mode in FIG. 6 (b).
The display changes to P ".

When the down switch SW2 is operated, the countdown of M1 is performed at each fall, and the mode and the display are switched in the wavy line direction of FIG. FIG. 7 is a diagram showing a change in display when the special mode setting switch SW4 is operated. When the special mode setting switch SW4 is turned on while any one of the first exposure mode group is set, the second exposure mode group is selected and "P", "S", Either "A" or "M" is displayed. In this case, it is shown that the first exposure mode group is still left.

FIG. 7A is a diagram when SW4 is turned on in the shutter priority mode with M1 = 1. In this state, the up switch SW1 or the down switch SW2
When is operated, the display unit 4 changes to the "Ps" display. M
0 becomes 1 and the special mode stored in M2 is set.

When M2 = 0, the portrait mode is set, and the display is lit on the display portion 5 at the location indicating the design mode indicating the portrait mode, as shown in FIG. 7B.
When M2 = 1, the souvenir photo mode is set, and the display is lit at a location indicating the design showing the souvenir photo mode on the display unit 5 as shown in FIG. 7C. Hereinafter, when M2 = 2, the landscape mode is set, and the display is lit on the display portion 5 at the location indicating the design.

When M2 = 3, the close-up mode is set, and the display is lit on the display section 5 at the place indicating the close-up mode. When M2 = 4, the sport mode is set, and the display is lit on the display portion 5 at the position indicating the design indicating the sport mode. When M2 = 5, the silhouette mode is set, and the display is lit on the display portion 5 at the position indicating the pattern indicating the silhouette mode.

When M2 = 6, the night view mode is set, and the display is lit on the display portion 5 at the location indicating the pattern indicating the night view mode. When M2 = 7, the dynamic mode is set, and the display is lit on the display portion 5 at the location indicating the pattern indicating the dynamic mode, as shown in FIG. 7D. When SW2 is turned off when M2 is 1 to 7, the exposure correction value and the flash light emission control mode have specific values according to the respective modes.

When M2 = 8, it means returning to the first exposure mode group, and a value corresponding to M1 is displayed. The normal exposure mode before selecting one of the special exposure modes is set to M1, and for example, when M1 = 0, “P” is displayed on the display unit 4, and when M1 = 1, the display unit 4 is displayed. "S" is displayed on the display, and when M1 = 2, the display unit 4
"A" is displayed on the display. When M1 = 3, "4" is displayed on the display unit 4.
M ”is displayed. If SW2 is turned off in this state,
It is possible to return to the setting of the first exposure mode group before pressing SW2. In this case, since the exposure correction value and the flash emission control mode are not rewritten, the setting value before the setting operation is effective.

In FIG. 7 (f), since the setting of the special exposure mode has been entered from the shutter priority mode, the shutter priority mode is displayed. After that, further up switch SW1
When is turned on, the count-up of M1 is performed at each fall, and the mode and its display are switched in the direction of the solid arrow in FIG. 7 accordingly. On the contrary, down switch SW
When 2 is operated, the countdown is performed at each fall and the mode and display are switched in the direction of the broken line in FIG.

According to this embodiment, since the mode for returning to the normal exposure mode is set in the special exposure mode group, the current setting can be changed even if the operation for calling the special exposure mode is started. No, you can return to the state before you started setting. Thereby, the normal exposure mode can be handled as if it is one of the special exposure modes. Although the exposure mode has been described as an example in this embodiment, the present invention can be applied to other modes such as an AF mode, a film feeding mode, and a photometry mode. Although SW3 and SW4 are provided as switches for selecting the exposure mode group, selection may be performed by one switch. Further, SW3 and SW4 are used for selecting the exposure mode group and SW1 and SW2 are used for changing the mode, but the selection switch may also be used as the mode changing switch. Further, the present invention can be applied even if the two exposure mode groups become the three exposure mode groups.

[0041]

According to the present invention, the second selecting means for selecting the photographing mode of the second group can select the photographing mode of the second group, and can switch between the first group and the second group. Since the photographing mode of the first group, which was selected immediately before the switching of the second unit, can be selected,
Even if the group is switched to the selectable state, the shooting mode of the first group immediately before the switching can be selected by the second selecting means. Therefore, for example, even if the user accidentally enters a mode of another group, it is possible to quickly select an appropriate mode without feeling bothersome.

According to the third aspect of the present invention, the set value set in the first group immediately before the switching from the first group to the second group is stored, and the second selecting means stores the photographing mode of the first group. When is selected, the setting value is set to the above-mentioned setting value, so that the setting value is not set again and the troublesomeness is further eliminated.
