Abstract
An image sensing apparatus has an image sensing element which accumulates received light as a charge, a mechanical shutter which travels to shield the image sensing element, and a scan unit which makes a scan for starting charge accumulation. The image sensing apparatus executes the scan for starting charge accumulation prior to traveling of the mechanical shutter and controls the scan for starting charge accumulation and traveling of the shutter to serve as a front curtain and a rear curtain of a shutter. Note that a scan pattern setting unit (113b) sets the scan pattern of the charge accumulation start scan based on information associated with a mounted photographing lens.
