Abstract
A camera device comprises a movable optical system, a driving unit which drives the optical system, and a control unit which controls the driving unit to move the optical system to a predetermined state by an initialization processing based on a startup program which does not comprise an operating system and then controls the driving unit based on the control program comprising the operating system.
Claims2
A camera device comprising:
- an optical system;
- a driving unit which drives the optical system;
- a control unit which:
- (i) when the camera device is started up in a state in which a recording mode for photographing is set, controls the driving unit to move the optical system to a predetermined state by an initialization processing based on a startup program which does not comprise an operating system and then starts a control based on a control program comprising the operating system, and
- (ii) when the camera device is started up in a state in which a playback mode for display is set, starts the control based on the control program comprising the operating system without moving the optical system to the predetermined state by the initialization processing based on the startup program;
- and
- a memory which stores the startup program and the control program, wherein when in the recording mode the control unit reads the startup program from the memory, starts to move the optical system to the predetermined state by the initialization processing based on the startup program, and then reads the control program from the memory without waiting for the optical system to reach the predetermined state.
