Patent ID: 7792354

Claim:
An apparatus for reproducing skin color in a video signal, the apparatus comprising: an input pixel value position discriminating unit which determines whether a value of an input pixel is in an atypical skin color (hereinafter called ‘atypical color’) area of a skin-color-area in chromaticity coordinates; and a standardization pixel value obtaining unit which, if it is determined that the value of the input pixel is in the atypical color area, adjusts the value of the input pixel so that the value of the input pixel approaches a typical skin color (hereinafter called ‘typical color’) area of the skin-color-area by adjusting the value of the input pixel to a standardized value obtained based on the typical color area, wherein the standardization pixel value obtaining unit receives a value of a distance between a point P in chromaticity coordinates at which values of color difference signals of the value of the input pixel are used, and a point M at which an average value of the color difference signals of the typical color area is used, and the standardization pixel value obtaining unit comprises: a change quantity calculating part which calculates standardized change quantities ΔCba and ΔCra of the values of the color difference signals of the value of the input pixel from an outermost value of color difference signals in the typical color area; and a standardization color difference signal calculating part which calculates standardized values Cba and Cra of the color difference signals of the value of the input pixel using the standardized change quantities, wherein the atypical color area and typical color area comprise a distribution of points.
