Claim One:
1. A display system, comprising: a plurality of individual projectors to collectively generate an image by projecting a plurality of overlapping sub-frames on a display surface, wherein the collectively generated image is formed based on a hypothetical high-resolution reference projector, wherein each of the plurality of overlapping sub-frames is generated based on geometric mappings between the plurality of individual projectors and the hypothetical high-resolution reference projector, wherein the plurality of overlapping sub-frames include overlapping regions and non-overlapping regions; at least one calibration camera to capture at least one image of the collectively generated image on the display surface and capture at least one image of an actual object that is separate from the display surface and the collectively generated image on the display surface and is positioned near the display surface, wherein the collectively generated image is a training image including at least one desired image feature and a plurality of other image features, wherein the at least one image is captured from the training image on the display surface; and a controller to: determine the geometric mappings between the plurality of individual projectors and the hypothetical high-resolution reference projector based on the at least one image of the collectively generated image; determine brightness and color settings of each of plurality of individual projectors to reduce discontinuities in the overlapping regions of the plurality of overlapping sub-frames; automatically adjust a color of an object appearing in the collectively generated image on the display surface based on the at least one image of the actual object; automatically determine, based on the at least one image, display characteristics associated with a just noticeable difference between the at least one desired image feature and the plurality of other image features, wherein the just noticeable difference is determined based on a human vision model representing a human observer; and adjust the plurality of individual projectors using the determined display characteristics.
