Patent ID: 8121406

Claim:
A preference color adjusting system implemented in an image multimedia device that has a processor programmed to control the system, said system comprising: a saturation calculator, which receives an RGB pixel and produces a saturation of the RGB pixel; a hue calculator, which receives the RGB pixel and produces a hue of the RGB pixel; a first lookup table device, which is connected to the hue calculator in order to output a first adjustment coefficient pair according to the hue of the RGB pixel, wherein the first lookup table device stores a plurality of first adjustment coefficient pairs; a second lookup table device, which is connected to the hue calculator in order to output a second adjustment coefficient pair according to the hue of the RGB pixel, wherein the second lookup table device stores a plurality of second adjustment coefficient pairs; and a mixer, which is connected to the saturation calculator, the first lookup table device and the second lookup table device in order to perform a weighting operation on the first adjustment coefficient pair and the second adjustment coefficient pair according to the saturation of the RGB pixel to thereby output an output coefficient pair.
