Abstract
An image processing apparatus which corrects input image data based on the image data and foreign substance information containing information on the position and size of a foreign substance includes a correction unit which corrects the influence of the shadow of the foreign substance contained in the image data, based on the image data and the foreign substance information, a still image uniformity determination unit which determines the uniformity of an image in a region around the foreign substance, a moving image uniformity determination unit which determines the uniformity of the image in the region around the foreign substance based on a determination criterion different from one applied to a still image, and a control unit which inhibits correction of the image data when the still image uniformity determination unit or moving image uniformity determination unit determines that the uniformity is less than or equal to a predetermined value.
