摘要： PROBLEM TO BE SOLVED: To provide an image processor capable of suppressing the unnatural raise of color saturation due to nonlinear transformation, while preserving a hue, and reducing false coloring. SOLUTION: An image signal input part 101 inputs the pixel signals of three RGB primary colors. A representative value calculating part 102 calculates the maximum level representative value X, which expresses the maximum level of the pixel signals included in a representative value calculation range, as a value representing the pixel signals in the representative value calculation range near the pixel to be noted. A transformation coefficient calculating part 103 calculates a luminance transformation coefficient kY and a color saturation transformation coefficient kC to be used for nonlinear transformation processing in response to a luminance transformation coefficient characteristic and a color saturation transformation coefficient characteristic, which are different in coefficient change corresponding to the maximum level representative value. A signal level transforming part 104 performs the nonlinear transformation processing of the pixel signals, so as to respectively transform the luminance and color saturation in response to the luminance transformation coefficient kY and the hue transformation coefficient kC, and transform the luminance and color saturation by individual change ratios without accompanying hue change.
