Patent ID: 8224177

Claim:
A digital camera, comprising: a light guide section that defines a space in which a light flux from a photographic lens to an imaging unit is guided; a mirror unit arranged inside the light guide section, that is adapted to rotate between a viewing position in which the mirror unit is inserted in a photographic light path from the photographic lens to the imaging unit to reflect the light flux and a photographing position in which the mirror unit is retracted from the photographic light path; a mirror unit control section that controls rotation of the mirror unit; a rotation instruction section that outputs a signal to rotate the mirror unit while no photography is performed to the mirror unit control section; an opening section provided in the light guide section that discharges from the light guide section air that is moved by the rotation of the mirror unit; a shutter arranged between the mirror unit and the imaging unit; and a shutter control section that controls opening and closing operation of the shutter, wherein the shutter control section controls the shutter to be changed from a state in which the shutter is closed to a state in which the shutter is opened and then again to a state in which the shutter is closed, during a time between a time before the mirror unit starts rotation from the viewing position to the photographing position and a time before the mirror unit reaches the photographing position after the mirror unit has started rotation from the viewing position to the photographing position.
