摘要
A preference color adjusting system includes a saturation calculator, a hue calculator, a first lookup table device, a second lookup table device, a mixer, and a UV converter. The saturation calculator receives an RGB pixel and produces a saturation of the pixel. The hue calculator receives the RGB pixel and produces a hue of the pixel. The first lookup table device stores plural first adjustment coefficient pairs for outputting a first adjustment coefficient pair according to the hue. The second lookup table device stores plural second adjustment coefficient pairs for outputting a second adjustment coefficient pair according to the hue. The mixer performs a weighting operation on the first and second adjustment coefficient pairs according to the saturation to thereby output an output coefficient pair. The UV converter adjusts U and V values of a YUV pixel corresponding to the RGB pixel according to the output coefficient pair.
