Abstract

An image processing apparatus for correcting degradation of an image due to an aberration of an optical imaging system with respect to image data obtained by sensing an object image entering through the optical imaging system using an image sensor. The image processing apparatus comprises selection means (1002) for selecting a filter to be used for recovery processing in accordance with an image sensing condition at the time of the image sensing, image processing means (1004) for performing recovery processing for the image data by using the filter selected by the selection means, and correction means (1005, 1006, 1007) for determining a correction value based on a difference between the value of a pixel before and after recovery processing by the image processing means, and correcting the pixel value before the recovery processing by the image processing means using the determined correction value.
