Patent abstract
Methods and systems for adjusting color-saturation contrast of the video signal. Statistical information based on chrominance or luminance measures is analyzed to derive a gain function. The gain function is also determined according to the detection result of an exceptional situation during statistical analysis. The gain function is applied to the video signal to modify the amplitude of the chrominance signal.
