IMAGE-PROCESSING APPARATUS AND IMAGE-PROCESSING METHOD

An image-processing apparatus includes: an acquiring unit configured to acquire a brightness characteristic value from input image data; a generating unit configured to generate information regarding a high-brightness area that is an image area of the input image data having a brightness greater than or equal to a first threshold value, based on the brightness characteristic value; and a processing unit configured to perform, on the input image data, unevenness reduction processing of reducing unevenness in at least one of brightness and color, wherein the processing unit performs, on the input image data, the unevenness reduction processing of reducing the unevenness more strongly in a case where the high-brightness area is bigger, based on the information.
