1. A method performed by a processing system, the method comprising:
- 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.

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.

10. An image display system comprising:
-
a first projector configured to display a first image frame on a first position on a display surface; a second projector configured to display a second image frame on a second position on the display surface, the second position partially overlapping the first position in an overlapping region on the display surface; a processing system configured to generate the first and the second image frames using first and second blend maps, respectively; wherein the first blend map includes a first plurality of factors, wherein each of the first plurality of factors is determined from a first plurality of distances between a corresponding pixel location in the first image frame and a plurality of edges of the first image frame and a second plurality of distances between a corresponding pixel location in the second image frame and a plurality of edges of the second image frame, wherein the second blend map includes a second plurality of factors, and wherein each of the second plurality of factors is determined from the first plurality of distances and the second plurality of distances. - View Dependent Claims (11, 12, 13)

14. A program product stored on a medium readable by a processing system, the program product comprising instructions executable by the processing system to:
-
determine 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; determine at least third and fourth distances between a second pixel location having a second pixel value in a second image frame and first and second edges of the second image frame, respectively, wherein the first pixel value and the second pixel value are configured to at least partially overlap on a display surface in response to being simultaneously displayed by first and second projectors, respectively; and determine a first factor configured to attenuate the first pixel value using the first, the second, the third, and the fourth distances. - View Dependent Claims (15, 16, 17, 18, 19, 20)
