1. A camera device comprising:
- an optical system;
a setting unit configured to set 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; and
a control unit which starts the initialization of the optical system before the operating system is started when a recording mode for photographing is set, and which suspends the initialization of the optical system when a playback mode for display is set.

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.

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; determining, when starting up the camera device, whether one of a recording mode for photographing and a playback mode for display is set; and starting the initialization of the optical system before the operating system is started when it is determined that the recording mode for photographing is set, and suspending the initialization of the optical system when it is determined that the playback mode for display is set. - View Dependent Claims (5, 6)

7. A computer readable medium storing a computer program for a camera device comprising an optical system and a driving unit which drives the optical system, the program being executable to cause the camera device to perform functions 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; determining, when starting up the camera device, whether one of a recording mode for photographing and a playback mode for display is set; and starting the initialization of the optical system before the operating system is started when it is determined that the recording mode for photographing is set, and suspending the initialization of the optical system when it is determined that the playback mode for display is set. - View Dependent Claims (8, 9)
