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. A feature amount of a color of a pixel in an image after restoration processing is calculated as a second color feature amount. High-frequency components included in the first color feature amount and the second color feature amount are attenuated according to a photographing condition at the time of photographing the image. 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.
