An image processing apparatus is disclosed. The image processing apparatus includes a color profile forming device. The color profile forming device includes a curved surface and table forming section, a cross-sectional surface forming section, a mapping section, and a color profile forming section. The curved surface and table forming section forms a curved surface and forms a mapping table by point group setting. The cross-sectional surface forming section forms a cross-sectional surface of a second gamut. The mapping section performs mapping of a color signal group of a first gamut on the cross-sectional surface of the second gamut by referring to the mapping table. The color profile forming section forms an LUT for a user corresponding to a selected hue, a selected curved surface, and a selected mapping table, based on input and output images whose color signals have been converted by the mapping table.
