Camera device and method and program for starting the camera device

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.

1 . A camera device comprising:
 an optical system;   a driving unit which drives the optical system; and   a control unit which, when the camera device is started up, controls the driving unit to start 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 predetermined control based on a control program comprising the operating system without waiting for the optical system to reach the predetermined state.   
   
   
       2 . The camera device according to  claim 1 , wherein the control unit
 (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 start to move the optical system to the predetermined state by the initialization processing based on the startup program which does not comprise the operating system, and then starts the predetermined control based on the control program comprising the operating system without waiting for the optical system to reach the predetermined state, and   (ii) when the camera device is started up in a state in which a playback mode for display is set, starts the predetermined control based on the control program comprising the operating system without starting to move the optical system to the predetermined state by the initialization processing based on the startup program.   
   
   
       3 . The camera device according to  claim 1 , further comprising:
 a memory which stores the startup program and the control program, and   wherein 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.   
   
   
       4 . The camera device according to  claim 3 , wherein the memory stores the control program continuously after the startup program. 
   
   
       5 . A method for staffing a camera device comprising an optical system, the method comprising:
 when the camera device is started up, starting 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   after a movement of the optical system to the predetermined state is started, starting a predetermined control based on a control program comprising the operating system without waiting for the optical system to reach the predetermined state.
