Abstract
A photographing apparatus includes an imaging optical system to guide light from a subject, a movement mechanism to move the imaging optical system, a sub control section to move the imaging optical system toward a predetermined position with the aid of the movement mechanism when a power supply is turned on, and a main control section to execute system initialization when the power supply is turned on, and to move the imaging optical system with the aid of the movement mechanism and interrupt the movement of the imaging optical system at the predetermined position. The sub control section may also start a lens barrel initialization processing to drive the lens barrel from a non-photographing position to a photographing standby position while the main control section executes system initialization, and the main control section may drive the lens barrel to the photographing standby position after the system initialization is finished.
