... Philips Semiconductors YUV one chip picture improvement based on luminance vector-, colour vector- and spectral processor S KIN TONE CORRECTION Skin tones are very sensitive for transmission (hue) errors, because we have an absolute feeling for skin tones. To make a picture look free of hue error, the goal is to make sure that skin tones are put at a correct colour ...
