Pixel correction processing apparatus, image processing apparatus, pixel correction processing method, program, and storage medium

摘要

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.
