Image sensing apparatus cleaning operation and control method of said cleaning operation
First Claim
1. 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.

Abstract
Image sensing apparatus having an image sensing element for sensing an object of shooting is provided. According to one aspect of the invention, when a cleaning mode is designated and executed to remove a foreign substance in the neighborhood of and on the image sensing element, the remaining amount of a battery which supplies electric power to the image sensing apparatus is detected by a voltage detector. If the remaining amount of the battery declines to a first predetermined value or less, a warning is issued by a lamp or a sound production unit. Moreover, if the remaining amount of the battery is the first predetermined value or less, a shift to the cleaning mode is prohibited. Furthermore, if the remaining amount of the battery declines to a second predetermined value or less, which is a lower value than the first predetermined value, mirror-down processing is performed so that cleaning operation cannot be executed.

3. A control method of a single lens reflex image sensing apparatus for capturing an image of object by an image sensing element, comprising the steps:
-
designating a cleaning mode for removing a foreign substance in a neighborhood of or on a photoreceptive surface of the image sensing element; detecting an output voltage of a battery for supplying electric power to the single lens reflex image sensing apparatus; moving up a mirror to allow a cleaning operation in the cleaning mode for removing the foreign substance, in a case where the cleaning mode is designated in said designating step and the output voltage detected in said detecting step is a predetermined value or more; and moving down the mirror in order to forcefully terminate the cleaning operation, in a case where the output voltage detected in said detecting step declines to the predetermined value or less in the cleaning mode. - View Dependent Claims (4)
