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.

Abstract: An image processing apparatus capable of properly suppressing coloring caused by image restoration processing. A feature amount of a color of a pixel in an image before restoration processing is calculated as a first color feature amount. Image restoration processing is performed on the image using an image restoration filter.

Pixel values of the image after restoration processing are corrected based on the first color feature amount and the second color feature amount of which the high-frequency components are attenuated.
