Abstract
A method of displaying an image with a display system includes receiving image data for the image. The method includes generating a first sub-frame and a second sub-frame corresponding to the image data. The method includes projecting the first sub-frame onto a target surface using a first projector light source. The method includes projecting the second sub-frame onto the target surface using a second projector light source, wherein the first and the second sub-frames at least partially overlap on the target surface, and wherein the first and the second light sources have substantially different spectral distributions.
