Patent ID: 6940529

Claim:
A graphics system for correcting display distortions, wherein the graphics system comprises: a graphics processor which is operable (a) to receive graphics data, (b) to select sample positions in a two-dimensional viewport, and (c) to compute sample values at the sample positions based on the receive graphics data; a sample buffer coupled to the graphics processor and configured to store the sample values; and a first calculation unit operable to select a first plurality of first virtual pixel positions in the two-dimensional viewport, to compute firs pixel color values at the first plurality of first virtual pixel positions, and to provide the first pixel color values as output to be displayed on a first display device; wherein the first calculation unit is configured to compute the first pixel values by filtering samples, from the sample buffer, neighboring each of the first virtual pixel positions; and wherein the first calculation unit selects the first plurality of first virtual pixel positions in the two-dimensional viewport in order to compensate for a first physical distortion in positions of a first set of first physical pixels generated by the first display device on a display surface.
