FIG. 9 is an example of a flow chart showing the outline of the operation of the digital photographing back cover 2 mounted on the camera body 1. The following processing is performed by the D-CPU 20.
Performed by 9. In addition, the back cover 2 for digital photography
The (D-CPU 209) is a DX terminal 111 and an adjustment terminal 1.
It is assumed that various kinds of information can be transmitted to and from the camera body 1 (camera CPU 116) via 08 and the communication terminal 207.

First, the camera body 1 (camera CPU 11
It is determined whether the exposure start signal is received from 6) (step # 201). When it is determined that the exposure start signal has not been received (NO in step # 201), the process returns to step # 201 (standby state is received until the exposure start signal is received). If it is determined that the exposure start signal has been received (YES in step # 201),
The integration operation (charge accumulation operation) of the CCD of the electronic image pickup unit 201 is executed (step # 203).

Then, the camera body 1 (camera CPU 11
It is determined whether the exposure completion signal is received from 6) (step # 205). When it is determined that the exposure completion signal has not been received (NO in step # 205), the process returns to step # 203 (the CCD integration operation of the electronic image pickup unit 201 is continued until the exposure completion signal is received. ). If it is determined that the exposure completion signal has been received (YES in step # 205), C of the electronic image pickup unit 201 is displayed.
The integration operation of the CD is completed, and image data is formed from the accumulated charges (image signal) (step # 207).

Next, the camera body 1 (camera CPU 11
It is determined whether or not the photographing data is received from 6) (step # 209). If it is determined that the shooting data has not been received (NO in step # 209),
The process returns to step # 209 (standby state until the image data is received). If it is determined that the shooting data has been received (YES in step # 209), the information acquisition unit 250 causes the camera CPU 116 (information output unit 1).
The photographing information from (50) is acquired, and the photographing information is stored in the memory card unit 203 in association with the image data from the electronic image pickup unit 201 which is photographed this time (step # 211).

FIG. 10 is an example of a screen view displayed on the monitor 204 by the display control unit 251. (A) is a screen view of an image display screen 400 on which image data is displayed, (b) is a screen view of a shooting information display screen 410 on which shooting information corresponding to the image data is displayed, (c)
FIG. 4 is a screen view of a simultaneous display screen 500 in which image data and corresponding image information are simultaneously displayed on one screen.

On the image display screen 400, people 401 and 402 are displayed in the lower right part of the screen. In the shooting information display screen 410, a shooting information item name 411 is displayed on the left side of the screen, and a shooting condition state 412 corresponding to the item name 411 is displayed on the right side of the screen. For example, a display in which the item name 411 is “Shutter” and the state 412 is “1/250” indicates that the shutter speed is “1/250 seconds”. The display in which the item name 411 is “FNo.” And the state 412 is “F5.6” is the aperture value (F
It means that the value) is “5.6”.

In the simultaneous display screen 500, the persons 401 and 402 are displayed in the lower right part of the screen, and the item name 411 of the shooting information and the shooting condition state 412 corresponding to the item name 411 are displayed in the upper left part of the screen. . The image display screen 40
0, the photographing information display screen 410, and the simultaneous display screen 500 are selected by externally operating a predetermined button, switch, or other operation member of the digital photographing back cover 2, and the display control unit 251 accepting the operation. . The image data stored in the memory card unit 203 is selected in the same manner. In this way, the shooting information, which is the shooting condition under which the image corresponding to the image data was shot, is displayed on the monitor 204, so that the shooting information can be easily confirmed.

The present invention can take the following forms.

(A) In this embodiment, the DX terminal 111 and the adjusting terminal 108 of the camera body 1 and the communication terminal 20 are used.
7 and the back cover 2 for digital photography from the camera body 1
Although the case where the transmission path for transmitting the information is formed has been described, the transmission path may be formed by other transmission means. For example, a configuration may be adopted in which the camera body 1 is provided with a light emitting unit and the digital image capturing back cover 2 is provided with a light receiving unit, and an optical transmission path is formed. Alternatively, the camera body 1 may be provided with a transmitter, and the digital image capturing back cover 2 may be provided with a receiver so that a transmission path is formed by wireless communication.

(B) In the present embodiment, the DX terminal 111 and the adjusting terminal 108 of the camera body 1 and the communication terminal 20.
7 and the back cover 2 for digital photography from the camera body 1
The case where a transmission path for transmitting information to the camera is formed has been described, but the DX terminal 111 and the adjustment terminal 1 of the camera body 1
A transmission path may be formed by at least one of 08 and the communication terminal 207.

(C) In this embodiment, the case where the photographing information is displayed on the monitor 204 of the digital photographing back cover 2 has been described, but the photographing information may be output as a voice. In this case, the image data is displayed on the monitor 204.
You can check shooting information while watching.

(D) In the present embodiment, when the simultaneous display screen 500 for displaying two pieces of information in an overlapping manner when simultaneously displaying image data and shooting information on the monitor 204 of the digital photographing back cover 2 is used However, the screen may be displayed in a divided screen format in which the screen is divided into an area for displaying image data and an area for displaying shooting information.
In this case, since the image data and the shooting information do not overlap, each can be seen more clearly.
