Patent ID: 8363067

Claim:
A circuit for independently processing a plurality of regions of an image to be displayed on a display device, the circuit comprising: a plurality of transformation modules, each one of said transformation modules having an input for receiving a pixel output from a graphics processing system and forming part of said image, and an output for transmitting a transformed pixel, each one of said transformation modules determining an output value for said transformed pixel; a multiplexer having a plurality of inputs, each one of said inputs connected to a corresponding output of said plurality of transformation modules, an output for selectively transmitting the transformed pixel from one of said plurality of transformation modules, and a selector line; and a selection module operatively connected to said selector line of said multiplexer and configured to cause the multiplexer to output the transformed pixel from one of the plurality of transformation modules as a function of a position of the pixel in the image, at least one region comprising the position, a priority level associated with each region, and a transformation associated with the region of a highest priority level.
