Abstract:
1. An image processing apparatus for performing recovery processing of image data to correct degradation of the quality of an image due to an aberration in an optical imaging system, the image data obtained by sensing an object image entering through the optical imaging system using an image sensor having a plurality of pixels, where each pixel of image sensor is covered with one of a plurality of color filters, the image processing apparatus comprising: a separation unit configured to separate image data of the plurality of colors of the color filters into image data of the respective colors of the color filters; a plurality of image processing units each configured to perform recovery processing by filter processing image data of one of the respective colors separated by the separation unit; and an interpolation processing unit configured to perform color interpolation processing of each pixel for the image data having undergone the recovery processing, wherein the separation unit is further configured to separate image data of a color whose spatial frequency characteristic is higher than that of another color, due to an arrangement of the plurality of color filters of the plurality of colors into a plurality of image data of the same color so that the plurality of image data of the same color have the same spatial frequency characteristic as the image data of the another color, and wherein the interpolation processing unit is further configured to perform the color interpolation processing by using the plurality of image data of the same color.
