Abstract: An image processing apparatus which performs recovery processing of correcting a degradation in image due to an aberration in an optical imaging system, with respect to image data of a plurality of colors, comprising: a separation unit configured to separate image data into image data of the respective colors, and further separate image data of a color whose spatial frequency characteristic is higher than that of another color due to an arrangement of color filters of the plurality of colors into a plurality of image data of same color so as to have the same spatial frequency characteristic as that of the other color; a plurality of image processing units configured to perform recovery processing by filter processing for each of the separated image data; and an interpolation processing unit configured to perform color interpolation processing of each pixel for the image data having undergone the recovery processing
