Abstract

Color correction of an image is implemented with a small circuit scale. A color correction section performs a color correction process on a pixel group-by-pixel group basis, and each pixel group is comprised of a plurality of adjoining pixels. A representative point generation section generates, e.g., a green (G) image signal of a representative point located as an imaginary point in the pixel group. A subtraction section subtracts the G-image signal of the representative point from an image signal of a G-pixel in the pixel group. A representative point color correction section performs the color correction process on the G-image signal of the representative point. An addition section adds the color-corrected G-image signal of the representative point to the output of the subtraction section.
