Abstract
An image processing apparatus capable of properly suppressing coloring caused by image restoration processing. A feature amount of a color of pixels in RAW image data obtained through photographing via an image pickup optical system is calculated as a first color feature amount. Restoration processing is performed on the RAW image data using a restoration filter for improving image quality degraded due to aberration of the image pickup optical system to thereby generate restored image data. A feature amount of a color of pixels in the restored image data is calculated as a second color feature amount. A pixel value of the restored image data is corrected according to a result of comparison between an amount of change in the second color feature amount with respect to the first color feature amount and a threshold value which is set based on a predetermined condition.
