ABSTRACT:
An image rendering system renders a color image in which each pixel is associated with a respective aim color value. A quantizer selecta a respective quantized value indicating a color from a palette of colors for each pixel, in dependence on the aim color value associated with that pixel. The pixels are rendered with the colors indicated by the respective quantized values. The palette consists of a proper subset of the set of all colors that the aim color values can represent, and contains at least one palette color which does not lie on an RGB boundary, and is perceptually closer than any other of the palette color values to an RGB boundary color belonging to said set. For pixels for which the aim color value represents said RGB boundary color the quantizer means selects a quantized value indicating a further palette color, that lies on the RGB boundary.
