PROBLEM TO BE SOLVED: To reduce color blurring that is emphasized in a defocused area, when image restoration is performed.SOLUTION: An image processing apparatus performs image processing on an input image produced by image pickup of a scene through an optical system 101, the scene including a plurality of objects whose object distances from the optical system are mutually different. The apparatus includes a filter acquisition section 4b for acquiring a chromatic aberration correction filter for reducing a chromatic aberration component contained in the defocused area in the input image and an image restoration filter for reducing a blur component contained in the input image; and a processing section 4b, by which chromatic aberration correction processing that uses the chromatic aberration correction filter and image restoration processing that uses the image restoration filter are applied to the input image. The filter acquisition section acquires the chromatic aberration correction filter by using information on chromatic aberration of the optical system, information on a focal distance of the optical system in the image pickup, and information on the distances to the plurality of respective objects. |
