Summary:PROBLEM TO BE SOLVED: To reduce the consumption of color materials during image output while preventing undesired deterioration in picture quality. SOLUTION: A histogram information acquiring means 351 calculates a luminance histogram of an input RGB image and sends a dynamic range as histogram information thereupon to a color material saving processing means 352. The color material saving processing means 352 performs color material saving processing on a CMYK image after conversion by a color conversion means 350 such that as the dynamic range is larger, the color material saving processing is performed more intensely.
