ABSTRACT:
Image processing includes defining chromaticity regions according to different luminance levels, and when the luminance of a pixel corresponds to one of the luminance levels, and a chromaticity vector of the pixel is within a chromaticity region corresponding to the luminance level, adjusting the chromaticity vector of the pixel.
