With the above-described configuration, the photographing conditions and the photographing state data are stored in the memory 7 and displayed on the display unit 6A. In the present embodiment, the store in the memory 7 and the display on the display unit 6A are externally input. It is reset when switch information is input from the switch 5, and prepares for shooting conditions, shooting state data display and storage for the next shooting. The operation processing procedure of this embodiment will be described in more detail with reference to FIG.
First, the contents of the memory are initialized and reset (step S1), and photographing conditions are set based on measurement data from the photometric circuit 2A and operation information of various keys from the external input switch 8 (step S2). Thereafter, it is determined whether or not a release has been performed (step S3). If not, the process returns to the initialization processing of step S1, and if the release has been made, the subject image is recorded via the recording / reproduction system circuit 4. (Step S4). Then, the above photographing condition and photographing state are output and stored in the memory 7 (step S5), and displayed on the display unit 6A via the display system circuit 6 (step S5).
6). Thereafter, it is determined whether or not there is key operation information from the external input switch 5 (step S7). If there is no key operation information, it is determined whether or not the power OFF timer has expired (step S8). If the power-off timer has expired, the power 1 is turned off (step S9), and if not, the process returns to the display processing in step S6. If there is an external input switch in step S7, the display so far is reset (step S10), and the storage contents of the memory 7 are reset (step S11).
Returning to the process of step S1, the process corresponds to storage and display of the next shooting condition and the like. The procedure for setting the photographing conditions in step S2 is, for example, a procedure as shown in FIG. First, it is determined whether or not the zoom key (SW) has been operated (step S21).
The zoom motor 8C is driven through (step S2).
2) Take in the zoom encoder signal (for position detection) of the zoom motor 8C (step S23). If the zoom key is not operated in step S21, the current zoom encoder signal is fetched in step S23, and the zoom encoder signal is stored in the memory 7. Next, it is determined whether or not there is an AF distance measurement signal (step S25). If there is no AF distance measurement signal, the process returns to step S21, and if there is, the AF motor 8B of the AF input system is driven via the drive system circuit 8. (Step S26), the AF encoder signal is captured (Step S27), and the AF encoder signal is stored and stored in the memory 7 (Step S26).
28). Thereafter, a photometric signal from the photometric circuit 2 is received (step S29), an appropriate exposure is obtained by calculation (step S30), and a corresponding shutter speed, aperture, strobe, and camera shake corresponding signal are output (step S31). These corresponding signals are stored in the memory 7 (step S3).
2). Then, it is determined whether there is a request for strobe preparation (step S33). If yes, the strobe is charged (step S34), and if no, the process ends. The photographing conditions at the time of release and storing and displaying the photographing state in the memory will be described with reference to FIG. The corresponding signals such as the shutter speed, the aperture, and the strobe are read from the memory 7 (step S41), and the drive system circuit 8 is read.
The actuators of the respective units such as 8A to 8D are driven via the controller (step S42), and images are recorded via the recording / reproducing system circuit 4. Thereafter, it is confirmed whether or not the recording is completed (step S44). When the recording is completed, the recording (completion) signal is stored in the memory 7 (step S45). (Step S46). Then, the photographing condition and the photographing state data are read out from the memory 7 (step S47), a display signal is outputted to the display system circuit 6 (step S48), and displayed on the display unit 6A such as an LCD (step S49). Furthermore,
It is determined whether there is an external switch input (step S50),
If there is, the process returns to the display of steps S10 and S11 in FIG.
It is determined whether or not the power-off timer has ended (step S51). If the power-off timer has expired, the memory 7 is reset (step S52). If not, the display returns to step S49 and continues to be displayed. A display timer for timer control of the display time is provided, and ON / OFF of the display timer is determined between step S50 and step S51 (step S53).
