1. A method for applying blending values to projector pixels in a system where two or more projectors project onto a surface and an image projected from one projector overlaps with at an image from at least one other projector comprising: projecting from a first projector a first image onto a display area; projecting from a second projector a second image onto the display area at the same time the first image is being projected, the second image overlapping the first image in an overlap portion of the display area to form a double projector overlap image; projecting from a third projector a third image onto the display area at the same time the first and second images are being projected, the third image overlapping the first and second images in an overlap portion of the display area to form a triple projector overlap image; determining if a first projector pixel projects onto the surface to form the triple projector overlap image, and if the first projector pixel projects onto the surface to form the triple overlap image, comparing first and second blending values, the first blending value associated with one pair of projectors and the second blending value associated with a different pair of projectors, and selecting the largest blending value, multiplying the largest blending value by a scale factor to obtain a resultant blending value, and assigning the resultant blending value to the first projector pixel.
