Abstract
In order to emphasize saturation without causing color compression, a saturation correction curve is determined such that color difference data relating to one pixel is not corrected when it represents maximum saturation or minimum saturation which saturation data relating to the one pixel can take, while being corrected when it represents intermediate saturation between the maximum saturation and the minimum saturation. Even if the saturation of color difference data Cb and Cr is corrected, it is possible to prevent color compression from occurring by the saturation of the color difference data Cb and Cr whose saturation has been corrected.
