FIG. 4 shows a start-up flowchart after the power switch of the camera is turned on. Power switch 68
Is turned on, and the power switch ON flow is started (step S401). Initialize the hardware and software required for the camera system (step S40).
2). By checking the state of the mode dial 60, it is determined in which mode the camera should be activated (step S403).

Here, it is determined whether the mode is the photographing mode or the reproduction mode, and a process suitable for each is executed. When starting in shooting mode, it is necessary to extend the lens for shooting. First, for that purpose, it is checked whether or not the lens position is in a position where photographing is possible (step S40).
4). If it is determined that the lens position cannot be photographed, the lens is driven to the photographing position (step S405). After the lens is driven, the lens position is confirmed again, and the lens drive is repeated until the lens position becomes an image-capable position. When the lens position is ready for shooting, the hardware and software necessary for shooting are initialized (step S4).
06), the camera is ready to take a picture.

FIG. 5 shows a shutdown flowchart after the power switch of the camera is turned off.

The power switch 68 is turned off, and the power switch OFF flow is started (step S501). First, the collapsing control method designated by the operation unit 70 is confirmed, and a process suitable for each is executed depending on whether the mode is the automatic mode or the continuous lens extension mode. If the lens extension mode is always set, it is not necessary to store the lens, so the camera system is powered off (step S506), and the camera is powered off (step S507).

When the auto mode is set, it is confirmed by the adapter detection switch 66 whether or not the conversion lens 600 or the like is attached to the camera (switch S503). When it is detected that the conversion lens 600 or the like is attached, it is not necessary to store the lens, so that the power of the camera system is turned off (step S506), and the camera is turned off (step S507).

If the conversion lens or the like is not attached, the lens is stored. First, the position of the lens is checked to see if it is in the storage position (step S504). If it is not in the storage position, the lens is driven in the storage position direction (step S505). The lens position is confirmed and the lens is driven repeatedly until the lens position reaches the retracted position. When it is confirmed that the lens can be moved to the retracted position, the power of the camera system is turned off (step S506), and the power of the camera is turned off. (Step S507).

In this way, when the lens extension mode is always selected by the operation unit 70 or when the conversion lens 600 or the like is attached, the power supply OFF process does not perform the lens storage operation. Therefore, after turning off the power switch, the camera actually turns on the power.
The time to reach FF can be significantly shortened.
In the next power-on process, the lens is already extended and the lens position is ready for shooting, so the time from turning the power switch on until shooting is possible is significantly reduced. can do. At the same time, the power consumption is reduced because the lens collapsing operation is not performed when the power is turned on / off.

In the above embodiment, the case where the conversion lens 600 is attached to the camera as shown in FIG. 2 has been described as an example. However, this is not limited to the conversion lens and, for example, when the camera is used underwater. The present invention can be applied even to a marine pack to be mounted on. If the structure is such that the adapter detection switch 510 of FIG. 2A is pushed by mounting the marine pack, the same effect as mounting the conversion lens can be obtained.

Further, in the above embodiment, it is possible to select whether or not the lens is housed when the power is switched from ON to OFF, but the present invention is not limited to this, and the power supply is not limited to this. When you switch from OFF to ON, you can select whether or not to extend the lens,
Whether to store the lens when switching the state of another camera, not the power supply, for example, when switching from shooting mode to playback mode, or whether to extend the lens when switching from playback mode to shooting mode The present invention can be applied even if it is possible to select whether or not to do so.

Although the embodiment has been described with a digital camera as an example, the present invention can be effectively applied to a silver halide camera, and the same effects as those of the above embodiment can be obtained.

Here, each functional block and processing procedure shown in the above various embodiments may be configured by hardware, or may be a CPU or MPU, ROM and R.
It may be configured by a microcomputer system including an AM and the like, and its operation may be realized according to a work program stored in a ROM or a RAM.
