Abstract

A camera device comprises a movable optical system, a driving unit which drives the optical system, and a control unit which makes the driving unit start driving of the optical system to a predetermined state by an initialization of the optical system by using an interrupt processing which is executed by setting an interrupt processing routine before the operating system is started, when the camera device is started up in a state in which an operation mode for photographing is set.

Claims

1. A camera device comprising:

an optical system which, upon initialization, is driven to a predetermined state when the camera device is started up;

a setting unit configured to set the initialization of the optical system to drive the optical system to the predetermined state as an interrupt processing of an operating system before the operating system is started, when the camera device is started up in a state in which a recording mode for photographing is set; and

a control unit configured to start the operating system after the initialization of the optical system is set.

2. The camera device according to claim 1, wherein said optical system comprises a movable lens.

3. The camera device according to claim 1, wherein said optical system comprises a sinkable lens.

4. A method for starting a camera device comprising an optical system, the method comprising:

setting an initialization of the optical system to drive the optical system to a predetermined state as an interrupt processing of an operating system before the operating system is started, when the camera device is started up in a state in which a recording mode for photographing is set; and

starting the operating system after the initialization of the optical system is set.
