Title:
SYSTEMS AND METHODS FOR LIGHT FIELD MODELING TECHNIQUES FOR MULTI-MODULATION DISPLAYS
Document Type and Number:
WIPO Patent Application WO/2015/023762
Kind Code:
A3
Abstract:
Dual and multi-modulator projector display systems and techniques are disclosed. In one embodiment, a projector display system comprises a light source; a controller, a first modulator, receiving light from the light source and rendering a halftone image of said the input image; a blurring optical system that blurs said halftone image with a Point Spread Function (PSF); and a second modulator receiving the blurred halftone image and rendering a pulse width modulated image which may be projected to form the desired screen image. Systems and techniques for forming a binary halftone image from input image, correcting for misalignment between the first and second modulators and calibrating the projector system - e.g. over time - for continuous image improvement are also disclosed.
