Patent ID: 8102332

Claim:
Tangible computer-readable media embodying instructions executable by a computer to perform a method comprising: receiving a first digital image representing a first composite projection on a display surface, wherein each first composite projection comprises a plurality of overlapping component projections, wherein each of the component projections is generated by a respective projector; and generating one or more respective first intensity scaling maps for each of the projectors, comprising, for each of the first intensity scaling maps identifying a displayed non-overlap projection region for the projector associated with the first intensity scaling map based on the first digital image, wherein the displayed non-overlap projection region is that portion of the respective first component projection that is within a maximum display area of the composite projection, but does not overlap with any other component projection, and generating a first intensity scaling map for the projector, comprising determining a distance to the nearest pixel within the displayed non-overlap region of the projector for each pixel outside the non-overlap region of the projector, and assigning a first intensity scaling value to each pixel outside the displayed non-overlap region of the projector based on the respective distance; wherein a second composite projection is generated upon the display surface by the projectors based on a second digital image and the first intensity scaling maps.
