The keeper's note

A color display/projection apparatus that decomposes an image into subframes for high-speed multicomponent imagery using binary spatial light modulators.

Abstract

A process and apparatus provide high speed multicomponent imagery from high frame rate binary spatial light modulators. The process and apparatus decompose an image frame into a plurality of subframes such that each subframe in theplurality of subframes corresponds to an image component of the image frame. The process and apparatus sequentially illuminate, with a spatially addressable backlight, each of thesubframes displayed on a spatial light modulator segment through a lenslet array and at least one optical component onto a diffuser. Further, a process and apparatus provide high speed projection with multiple projectors. The process and apparatus decompose an image frame into a plurality of image components. Further, the process and apparatus associate each of the plurality of image components with each of a plurality of associated projectors. The process and apparatus concurrently projects the plurality of image components from theplurality of associated projectors.
