Abstract
A determining unit determines which one of a plurality of divided areas in color distribution a value of an input image single falls within. The plurality of divided areas are defined for each of R, G, and B color components, and the determining unit determines, for each color component, which one of the plurality of divided areas the value of the input image signal falls within. An image correcting unit reads correction coefficients corresponding to the determined divided area for each color component from a correction coefficient storing unit in which correction coefficients are registered for each of the color components and each of the divided areas. The image correcting unit calculates each of R, G, and B output values of an output image signal using the correction coefficients of the individual color components read from the correction coefficient storing unit.
