Patent ID: 7649657

Claim:
A method for adaptive adjustment of pixels in a color gamut based on a reference target color implemented by an adaptive apparatus, the method comprising: determining whether pixels of an input image are included in the color gamut to be converted using an equation of a straight line or an equation of a curve, which delimits the color gamut from another color gamut by a color gamut determination module, wherein the straight line or the curve form a color gamut boundary of the color gamut; calculating a representative value that shows color characteristics of pixels included in a color gamut by a target color determination module; calculating a final target color required to convert the representative value to approach a reference target point existing in the color gamut by a target color determination module; and converting the pixels included in the color gamut to approach the final target color by a color conversion module; wherein the representative value, the reference target point and final target color is included in the color gamut defined by the color gamut boundary.
