Abstract:
1. A video processing device, comprising: a luminance and saturation detector adapted to detect the luminance values and the saturation values of pixels of an input video signal, wherein the luminance and saturation detector includes: a white-point, saturation and hue modulator adapted to transform the luminance and saturation values of each pixel of the input video signal into a corresponding white-point correction factor, a second saturation correction factor, and a hue correction factor; a color gamut matrix generating unit adapted to generate a color gamut matrix in the perception domain based on the white-point correction factor, the second saturation correction factor, and the hue correction factor; a color gamut mapping unit adapted to multiply the pixels of the input video signal with the color gamut matrix; and a clipping unit adapted to clip the results of the color gamut mapping unit which are out of a predefined range.
