Abstract: A change degree deriving apparatus includes a receiving unit and a deriving unit. The receiving unit is configured to receive first image data of an object including an achromatic color and a first color and reference image data of the object. The first image data relates to the first color. The reference image data serves as a reference. The deriving unit is configured to derive a change degree of the object from a first difference based on the first image data and the reference image data received by the receiving unit. The first difference is a difference between the first image data and the reference image data, which occurs at a chromatic color portion when a portion corresponding to the achromatic color is set as a reference.

Abstract: A change degree deriving apparatus includes a receiving unit and a change acquiring unit. The receiving unit receives image data and new product image data.

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.
