Patent ID: 7106370

Claim:
An image sensing apparatus comprising: an image sensing device having an image sensing area which is divided into a plurality of image sensing sections each including a plurality of pixels which generate electric signals corresponding to amounts of incident light, and a plurality of output units respectively outputting the electric signals of said plurality of image sensing sections to outside of said image sensing device; a shutter adapted to open and close an optical path of incoming light to said image sensing device; a light source which emits light to at least a part of said image sensing area of said image sensing device so that the light is projected onto said plurality of image sensing sections; a controller that controls said shutter to close the optical path and controls said light source to emit light while said shutter closes the optical path; and a correction unit that corrects level differences, owing to characteristic difference of said plurality of output units, between the electric signals from said plurality of image sensing sections with the optical path opened on the basis of electric signals outputted by said plurality of output units with the optical path closed and said light source emitting light.
