ABSTRACT:
A color saturation value for at least some of the pixels in an input image is adjusted to provide an output image. In one aspect, for each pixel for which the color saturation value is adjusted, the color saturation value for the pixel is adjusted in dependence on both a brightness value and a color saturation value for said pixel. In another aspect, the adjusting is carried out by, for each of the at least some pixels, reading from a brightness values look-up table a brightness scale parameter corresponding to the brightness value of the pixel, reading from a color values look-up table a color scale parameter corresponding to the color value of the pixel, obtaining a final scale parameter for the pixel from the brightness scale parameter and the color scale parameter, and adjusting the color value for the pixel in accordance with said final scale parameter.
