Patent ID: 7483073

Claim:
A single lens reflex image sensing apparatus for capturing an image of object by an image sensing element, comprising: a battery for supplying electric power to the single lens reflex image sensing apparatus; an operation unit configured to designate a cleaning mode for removing a foreign substance in a neighborhood of or on a photoreceptive surface of the image sensing element; a voltage detector configured to detect an output voltage of said battery; a mirror controller configured to move up and down a mirror; a cleaning operation allowing unit configured to cause said mirror controller to move up the mirror to allow a cleaning operation, in a case where said operation unit designates the cleaning mode and the output voltage detected by said voltage detector is a predetermined value or more; and a termination unit configured to cause said mirror controller to move down the mirror in order to forcefully terminate the cleaning operation, in a case where the output voltage detected by said voltage detector declines to the predetermined value or less in the cleaning mode.
