Patent ID: 8111945

Claim:
A system for generating a blended picture, the system comprises: a storage unit adapted to store pixels of a first picture, pixels of a second picture, and alpha data; and a device coupled to the storage unit via at least one data channel, wherein the device comprises: a relevancy determination module adapted to determine a relevancy of pixels of at least one of the first picture and the second picture based upon values of alpha data associated with the pixels of the first picture, wherein the alpha data represents a degree of transparency of the pixels of the first picture to be overlaid over the second picture; an access controller coupled to the relevancy determination module, the access controller adapted to prevent a transfer of irrelevant pixels from the storage unit; and a blending unit coupled to the access controller, the blending unit adapted to provide a blended picture in response to values of the alpha data by blending relevant pixels of the first and second picture.
