APPARATUS AND METHODS FOR RAPID IMAGE RENDERING ON DUAL-MODULATOR DISPLAYS
First Claim
1. A controller for displaying an image on a display comprising a light source layer and a display layer, the controller comprising:
- means for determining driving values for light sources of the light source layer;
means for determining an effective luminance pattern of the light source layer at a first spatial resolution lower than a spatial resolution of the display layer;
means for increasing the spatial resolution of the effective luminance pattern to a second spatial resolution corresponding to the resolution of the display layer;
means for determining driving values for elements of the display layer based at least on image data and an output of the means for increasing the spatial resolution of the effective luminance pattern.

Abstract
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 are then combined to produce a total effective luminance pattern. Additional image display time reduction techniques are provided.
