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.
