Abstract
A full color image projection system is provided using two non-color-specific image sources and color-specific filters. The system is capable of projecting an image using one primary color from one image source and the other two primary colors from another image source. The system uses slower speed image sources than would be required with one source alternating between three colors, and exhibits higher resolution than would be obtained from a color-specific image source.
Claims16
An image engine, comprising:
- a first image source having a first response time for color operation at a first color depth, the first response time being greater than operation of the first image source at a second color depth;
- a second image source having a third response time for color operation at the first color depth, the third response time being greater than operation of the second image source at the second color depth;
- a color filter configured to direct first colored light to the first image source and to direct second colored light to the second image source;
- and
- an electro-optic color switch configured to alternately allow components of the second colored light to be directed to the second image source.
