Abstract

A converting unit converts a first color signal into a second color signal and a third color signal. A first correcting unit corrects a magnitude relation between hue angles of the third color signal such that a magnitude relation between hue angles of the second color signal corresponding to the first color signal is maintained in the hue angles of the third color signal. The first color signal is a device-dependent input red, green, blue color signal. The second color signal is a color signal of a hue, lightness, saturation color space. The third color signal is a color signal of CIECAM02 color space.
