Rapid image rendering on dual-modulator displays

Abstract From the Canadian patent

Apparatus and methods are provided that employ one or more of a variety of techniques for reducing the time required to display high resolution images on a high dynamic range display having a light source layer and a display layer. In one technique, the image resolution is reduced an effective luminance , pattern is determined for the reduced resolution image and the resolution of , the effective luminance pattern is then increased to the resolution of the display layer. In another technique, the light source layer's point spread function is decomposed into a plurality of components and an effective , luminance pattern is determined for each component. The effective luminance patterns …
