Abstract: Adjustment object color space containing movement source partial color space including a color of an object of conversion processing and movement destination partial color space including a color in which the conversion processing is performed so as to inscribe the spaces is handled as a conversion object region. The inside of the conversion object region is moved toward a target color so that coordinates of an adjustment object overlaps with coordinates of a point after movement and the boundary of a movement region moves little or does not move at all. As a result of this, a phenomenon such as a color jump or gradation inversion occurs little in the boundary portion to the outside of an adjustment object region. Therefore, maintenance of gradation continuity of an image of a color adjustment object and prevention of color inversion can be combined to make partial color adjustment.

When display, output or print is actually required, various image processings are executed by referring to modification information on only a work area with original image data left. Therefore, it is possible to easily enjoy image modification or the like with the original image data left as they are.
