Abstract
A dust removal apparatus of a photographing apparatus comprises a movable unit and a controller. The movable unit has an imaging device and is movable. The controller moves the movable unit on a plane that is parallel to a first direction and a second direction. The first direction is perpendicular to an optical axis of a photographing optical system that captures an optical image on a photographing surface of the imaging device. The second direction is perpendicular to the first direction and the optical axis. The controller moves the movable unit to a predetermined position that does not make contact with a boundary of a range of movement of the movable unit, and strikes the movable unit against the boundary of the range of movement in the second direction under the condition where a coordinate value in the first direction of the movable unit is held constant, as a dust removal operation.
