Patent ID: 8310720

Claim:
A color adjustment apparatus, comprising: an input unit for receiving an input operation; a color adjustment display unit for displaying orthogonal coordinate systems, wherein the orthogonal coordinate systems include a pre color adjustment hue axis and an adjustment target axis, wherein the adjustment target axis indicates a degree of adjustment of a hue, saturation, or lightness, wherein an adjustment line is displayed on each of the orthogonal coordinate systems, and wherein the adjustment line indicates a relationship between pre color adjustment and post color adjustment on the orthogonal coordinate systems; an adjustment line changing unit for changing the adjustment line in response to an operation by the input unit; and a color adjustment unit for adjusting a hue, saturation, and lightness of a target image in correspondence with the adjustment line changed by the adjustment line changing unit, wherein the adjustment line changing unit changes the adjustment line in a selected hue range by shifting a segment of the adjustment line, in response to the operation of the input unit, wherein the color adjustment display unit displays operating points on the adjustment line on the orthogonal coordinate system corresponding to the hue, and wherein an interval between the adjacent operating points is half of the hue range that is selected in response to the operation by the input unit.
