Abstract:
A system for generating a dithered color value, the system comprising:an over sampling buffer for generating multiple sub-samples representing each pixel;an offset generator having an input and an output, for generating offset values, the input of the offset generator coupled to receive information about a relative position of a sub-sample being dithered;an adjusted coordinate generator having a first input, a second input and an output, the adjusted coordinate generator producing adjusted coordinate values, the first input of the adjusted coordinate generator coupled to the output of the offset generator, and the second input of the adjusted coordinate generator coupled to receive pixel coordinates for the sub-sample being dithered; anda dither matrix having a first input, a second input and an output, for generating a dithered value for the sub-sample, the first input of the dither matrix coupled to the output of the adjusted coordinate generator, and the second input of the dither matrix coupled to receive a color value.
