ABSTRACT:
A method and apparatus for adjusting a color difference signal of an image includes a video signal processor. The video signal processor receives a luminance signal and color difference signals representing the image, and accesses a color saturation level from a color saturation level table stored in memory based on the color difference signals. The video signal processor then detects flesh tone in areas of the image based on the luminance signal and the color saturation level, and generates a flesh tone detecting signal based on results of the flesh tone detection.
