Antonio Colmenarez,Mi-Suen Lee,Tomas Brodsky,Hugo J. Strubbe,Peter J. Janssen,Michael D. Pashley +5 more
TL;DR: In this article, a combined display-camera has been proposed to provide an imaging operation which approximates that of a lens-based single-camera system, a pinhole camera system or other type of system.
Patent
High contrast illumination system for video projector
TL;DR: In this paper, a high contrast illumination system was proposed for use with light valves that have an array of reflective pivotable pixels and an asymmetric aperture is disposed in the light path with its longitudinal axis located along the pivot axis of the pixels.
Patent
Single panel color projection video display having control circuitry for synchronizing the color illumination system with reading/writing of the light valve
TL;DR: In this article, a color projection video system utilizing only a single light valve is described, where the image is projected by a projection lens onto a viewing surface, such as a screen, and circuitry includes circuitry to synchronize the illumination of the light valve with the video signal and to minimize video breakup when changing video sources.
Patent
Single panel color projection video display improved scanning
TL;DR: A color projection video system utilizing only a single light valve is described in this paper, where a white light source is separated into red, green and blue bands, and the image is projected by a projection lens onto a viewing surface, such as a screen.
Patent
Single panel color projection video display having improved scanning
TL;DR: In this article, a color video projection video system is described, where a white light source is separated into red, green and blue bands with dark guard bands spaced there between. But the color balance can be adjusted by changing the relative size of each color band with respect to the others.
