COLOR ENHANCEMENT

摘要

In an image processor, a color format converter (CFC) converts a pixel (Pi,j), which is expressed in an RGB color space, into a converted pixel (PCi,j), which is expressed in an YUV color space. A color shift vector generator (CSO, SVC) generates a color shift vector (SVi,j), which is expressed in the YUV color space, on the basis of the converted pixel (PCi,j). An inverse color format converter (ICFC) converts the color shift vector (SVi,j) into a color enhancement vector (EVi,j), which is expressed in the RGB color space. An adder (ADD) adds the color enhancement vector (EVi,j) to the pixel (Pi,j) so as to obtain a color enhanced pixel (PEi,j).
