Patent ID: 7348992

Claim:
An apparatus for color compensation of an input signal comprising: a chroma deflection generation unit to calculate a chroma deflection based on an input chroma signal detected from the input signal and a predetermined first reference value; a hue deflection generation unit to calculate a hue deflection based on an input hue signal detected from the input signal and a predetermined second reference value; a luminance deflection generation unit to calculate a luminance deflection based on an input luminance signal detected from the input signal and a predetermined third reference value; a skin tone mapping function generation unit to output a compensated chroma signal, a compensated hue signal and a compensated luminance signal after individually compensating the input chroma, hue, and luminance signals based on the chroma deflection, the hue deflection and the luminance deflection; and a color space conversion unit to respectively calculate the input chroma signal, the hue signal and the luminance signal by converting a color signal of the input signal in a color space, and transmit the chroma, hue, and luminance signals to the corresponding chroma deflection function generation unit, hue deflection function generation unit and luminance deflection function unit.
