PROBLEM TO BE SOLVED: To automatically correct a saturation optimum corresponding to the sharpness of an image. SOLUTION: An input image is separated into color data and luminance data by a color converting means 12, the correction quantity of the saturation is calculated from the respective data by a saturation correction quantity calculating means 13, and the saturation is corrected by a saturation correcting means 14. In the saturation correction quantity calculating means 13, concerning the image of a low saturation, the saturation correction quantity is suppressed so that over correction is prevented from being loaded to an achromatic portion. Besides, the image is divided into several areas, the saturation correction is performed on the basis of a saturation level in the area of the highest saturation level, a saturation level in the area of most contours or a saturation level in the area where skin colors are distributed much, and the optimum saturation correction matched with human senses is performed.
