Image sensing apparatus and control method of said apparatus

A single lens reflex image sensing apparatus for capturing an image of object by an image sensing element, comprising:

• power supply unit configured to supply electric power to the image sensing apparatus;
• detection unit configured to detect an electric power supplied from said power supply unit;
• designation unit configured to designate a shift to a cleaning mode to remove a foreign substance in a neighborhood of and on a photoreceptive surface of the image sensing element;
• cleaning mode setting unit configured to set the cleaning mode by moving up a mirror for the single lens reflex and making a shutter front curtain to travel;
• and
• warning issuance unit configured to issue a warning in a case where the electric power detected by said detection unit declines to a first predetermined value or less in a state where the cleaning mode is set by said cleaning mode setting unit in accordance with designation of said designation unit.

A control method of an image sensing apparatus for capturing an image of object by an image sensing element, comprising:

• a detection step of detecting electric power supplied to the image sensing apparatus;
• a designation step of designating a shift to a cleaning mode to remove a foreign substance in a neighborhood of and on a photoreceptive surface of the image sensing element;
• and
• a warning issuance step of issuing a warning in a case where the electric power detected in said detection step declines to a first predetermined value or less during execution of the cleaning mode designated in said designation step.

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 and 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;
• unit configured to allow removal of 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;
• 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
• unit configured to move down the mirror using said mirror controller 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.

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 removal of 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 and 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 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.
