ABSTRACT:
The gain difference between pixels is to be corrected for an image signal obtained by an image sensing element having a plurality of pixels. The first reference image is sensed without any object, and then an object is sensed. Gain correction is performed for the sensed object image by using the first reference image. To perform gain correction again, the second reference image is sensed without any object. Gain re-correction is performed for the object image having undergone gain correction by using the first and second reference images.
