Claim:
An image processing circuit comprising: a correction amount calculation section which calculates a correction amount from area-by-area correction amounts set respectively for two adjacent areas, corresponding to the hue of input image data, out of a plurality of areas into which a hue/saturation plane is divided; a correction coefficient calculation section for calculating a correction coefficient according to the lightness or the saturation of the input image data; a multiplier section for outputting a product of the correction amount and the correction coefficient; a color correction processing section which generates output image data by subjecting the input image data to color correction processing according to an output of the multiplier section; and a register for storing the area-by-area correction amounts referred to by the correction amount calculation section and a correction coefficient table referred to by the correction coefficient calculation section; wherein the correction coefficient table includes: a first correction coefficient table in which the lightness of the input image data and a first correction coefficient are associated, the first correction coefficient being set discretely with respect to the lightness of the input image data, and a second correction coefficient table in which the saturation of the input image data and a second correction coefficient are associated, the second correction coefficient being set discretely with respect to the saturation of the input image data, wherein the correction coefficient calculation section refers to the correction coefficient table and calculates the correction coefficient by supplementing areas between the discrete values of the first and second correction coefficients, respectively.
