ABSTRACT:
This invention has as its object to prevent degradation of the image quality caused by insufficient or excessive correction of a defective pixel, and realize high-speed, high-precision correction processing for a defective pixel. To achieve this object, an apparatus which performs correction for a pixel of an image sensing element formed from a plurality of pixels includes: (A) a memory unit which stores a plurality of correction data that have pieces of defective pixel address information and are used to correct outputs from defective pixels of the image sensing element; and (B) a correction processing unit which selects correction data for use from the plurality of correction data in accordance with a predetermined condition by a predetermined selection method including different types of selection standards, and performs defective pixel correction processing for an output from the image sensing element by using the selected correction data.
