1. A method of displaying an image with a display system, the method comprising:
- receiving image data for the image;
generating a first sub-frame, a second sub-frame, and a third sub-frame corresponding to the image data;
projecting the first sub-frame onto a target surface using a first projector light source;
projecting the second sub-frame onto the target surface using a second projector light source; and
projecting, the third sub-frame onto the target surface using a third projector light source, wherein the first, the second, and the third sub-frames at least partially overlap on the target surface, and wherein the first, the second, and the third light sources have substantially different spectral distributions and are each in separate and distinct projector devices.

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.
