ABSTRACT:
A method performed by a processing system includes determining at least first and second distances between a first pixel location having a first pixel value in a first image frame and first and second edges of the first image frame, respectively, and determining a first factor that is proportional to a first product of the first and the second distances and configured to attenuate the first pixel value in response to the first pixel value being displayed by a first projector on a display screen such that the first pixel value overlaps with a second pixel value displayed by a second projector.
