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;
an operation unit configured to designate a cleaning mode to remove 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/down a mirror;
a cleaning operation allowing unit configured to allow a cleaning operation for removing the foreign substance by moving up the mirror by said mirror controller in accordance with designation from said operation unit, in a case where the output voltage detected by said voltage detector is a first predetermined value or more;
a warning unit configured to issue a warning in a case where the output voltage detected by said voltage detector declines to the first predetermined value or less during the cleaning mode; and
a termination unit configured to move down the mirror using said mirror controller in order to forcefully terminate the cleaning operation, in a case where the output voltage detected by said voltage detector declines to a second predetermined value or less, which is a smaller value than the first predetermined value, during execution of 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.

2. A control method of a single lens reflex image sensing apparatus for capturing an image of object by an image sensing element, comprising:
-
a step of allowing a cleaning operation for removing a foreign substance by moving up a mirror in a case where an output voltage of a battery is a first predetermined value or more upon designation of a cleaning mode which is provided for cleaning a foreign substance in a neighborhood of or on a photoreceptive surface of the image sensing element; a step of issuing a warning in a case where the output voltage of the battery declines to the first predetermined value or less during the cleaning mode; and a step of moving down the mirror in order to forcefully terminate the cleaning operation in a case where the output voltage of the battery declines to a second predetermined value or less, which is a smaller value than the first predetermined value, during execution of the cleaning mode.
