FIG. 1B is a view showing a state in which a battery 111 is loaded in the battery chamber 110 instead of the connection of the DC plug 41.

In this state, the DC jack opening / closing lid 38
Is closed, and the locking claw 38b is separated from the outer cover 18. Therefore, the battery cover 37 can be easily opened.

Next, referring to the flowchart of FIG.
The operation of the camera according to the present embodiment will be described.

When the battery 111 is loaded into the battery compartment 110 of the camera or the DC plug 41 is attached to the DC jack 39, the operation of the main CPU 62 is started.
The subroutine "main sequence" is called. Then, first, in step S1, it is determined whether or not the power switch of the camera is turned on. Here, when the power switch is on, the process proceeds to step S4, and when the power switch is off, the process proceeds to step S2.

In step S2, the LCD panel 66 is turned off, and an instruction is given to the image processing LSI 67 to turn off the display of the LCD monitor 92. Next, in step S3, standby processing 1 is performed.

This standby processing 1 is performed before the operation of the main CPU 62 is stopped, and after the main CPU 62 is stopped.
U62 is for setting conditions for starting operation again. In the standby process 1, the operation is set to start when the power switch is turned on. Then, the operation of the main CPU 62 is stopped. When the standby is released, the subroutine is executed from the beginning of the “main sequence”.

In step S4, the taking lens 11 composed of the positive lens 46 and the negative lens 48 is extended from a retracted position (not shown) to a wide position. Then, in step S5, the LCD panel 66 is turned on, and in step S6, the main capacitor (not shown) included in the strobe circuit 69 is charged.

In step S7, the timer 1 (not shown) built in the main CPU 62 starts counting. The timer is a counter that is counted up every predetermined time. The counter value is set to a predetermined initial value, and counting is started.

Next, in step S8, the state of the release button 20 is determined. Here, the state of the first release switch (first release button) corresponding to the half-press operation of the release button 20 is determined. If the first release switch is off, the process proceeds to step S8, and if it is on, the process proceeds to step S15.

In step S9, the release button 2
It is determined whether a button other than 0 is turned on.
If the other button is turned on, step S10
Each process is executed, and if it is off, the process proceeds to step S11.

Next, in step S11, it is determined whether the power switch of the camera is turned on. When the power switch is on, the process proceeds to step S12, and when the power switch is off, the process proceeds to step S2.

The timer 1 started in step S7
Count overflows when a predetermined time elapses. Therefore, in step S12, it is determined whether or not the timer 1 overflows.

Here, if the timer 1 overflows, the flow shifts to step S13. On the other hand, if the timer 1 has not overflown, the flow shifts to step S8, and the subsequent processing is repeatedly executed. This is because when the operation switch such as the power switch is not operated even after the lapse of a predetermined time, the main CPU 6 is operated to save energy.
2 is brought into a standby state.

In step S13, the LCD panel 66 is turned off, and the image processing LSI 67 is instructed to turn off the LCD monitor 66. Next, a standby process 2 is performed in step S14. This standby process 2 is the standby process 1 executed in step S3.
Similarly to the above, before the main CPU 62 stops the operation, conditions are set for the main CPU 62 to start the operation again after the stop.

In the standby process 2, the operation is set to be started by a change of a switch linked to the operation button. Then, the operation of the main CPU 62 is stopped. If the standby is released, the above-described step S5
Run from

If the first release switch is turned on in step S8, the flow shifts to step S15 where the image processing LSI 67 is turned on. Next, in step S16, the subject luminance value is acquired from the photometric sensor 58.

Further, in step S17, the interval between the two images is obtained based on the signal input from the autofocus module 64, and the driving amount data of the photographing lens 11 for driving to the in-focus position is calculated. The motor 55 is driven according to the driving amount obtained here, and the focal positions of the lenses 46 and 48 of the photographing lens 11 are changed.

In step S18, the above-mentioned step S16
Based on the subject brightness value obtained in the above, a program diagram or the like corresponding to the shooting mode, and a film sensitivity detected by a film sensitivity detection circuit (not shown), a shutter opening time at which a proper exposure can be obtained by a known technique. Is calculated. Next, in step S19, a subroutine "photographing sequence" is called, and the CMOS imager 78 is called.
And exposure to the silver halide film 49 is performed.

Next, a second embodiment of the present invention will be described.
