Method and system for automatic color hue and color saturation adjustment of a pixel from a video source
A method for automatically adjusting chrominance data of an input pixel from a color video signal includes receiving and temporarily storing the chrominance data of the input pixel in a transmission format comprising a color difference representation and converting the chrominance data from the color difference representation in Cartesian coordinates to color hue and color saturation representation in polar coordinates such that color attributes of the input pixel can be analyzed according to hue and saturation values. The method also includes determining a hue adjustment value and a saturation adjustment value based on the color hue value and color saturation value associated with the chrominance data, applying the hue adjustment and the saturation adjustment directly to the chrominance data in its transmission format, and outputting the adjusted chrominance data to an output color video signal.
