Abstract: Flesh color pixels that constitute flesh color areas of a captured image are determined with respect to the three attributes of color: lightness, chroma and hue, and lightness-chroma distribution of the flesh color pixels is determined in a coordinate plane whose vertical and horizontal axes represent lightness and chroma respectively, and lightness-hue distribution of the flesh color pixels is determined in a coordinate plane whose vertical and horizontal axes represent lightness and hue respectively. Image data of the captured image is subjected to a color conversion process, so as partly to change the lightness-chroma distribution or the lightness-hue distribution of the flesh color pixels, to control color of the flesh color areas. For example, it is possible to raise chroma values or change hue of the flesh color pixels only in a high lightness zone.
