Abstract: Complicated adjustment, such as adjusting hue and saturation by varying value for each hue in which hue correction and saturation correction are performed on only an input having a specific value of a specific color component, is performed. In a color space including hue Hi, saturation Si, and value Vi, calculating a hue correction value HVh and a saturation correction value HVs by using the hue Hi and the value Vi as parameters allows the hue correction and the saturation correction to be performed based on the value and completely independently for hue axes of the hue. The correction value calculating circuit scale has no influence on the complexity of the correction. It is possible to calculate the correction values by a certain circuit scale no matter how complicated the correction is.
