Abstract
Projection displays include a highlight projector and a main projector. Highlights projected by the highlight projector boost luminance in highlight areas of a base image projected by the main projector. Various highlight projectors including steerable beams, holographic projectors and spatial light modulators are described.
Claims20
A method for displaying images, comprising:
- spatially modulating light according to a desired image;
- Fourier transforming the light representing the desired image onto a Fourier plane;
- and
- attenuating or eliminating one or more frequency components of the Fourier transformed light by a mask positioned on the Fourier plane.
