Stereoscopic imaging systems utilizing solid-state illumination and passive glasses

摘要

A stereoscopic display system employs narrowband illumination light beams and passive glasses with built-in interference filters. The system is also compatible with multiple viewing functions.

1. A method for stereoscopic imaging, comprising:
processing input right and left image data to scale colors of right and left color spaces into a common color space, the right and left color spaces being defined by colors of first and second light wavelength spectra having different wavelength peaks within the same color range; modulating a first image engine with the processed right image data in synchronism with illuminating the image engine with light having the first light wavelength spectrum to produce a right image; and modulating a second image engine with the processed left image data in synchronism with illuminating the image engine with light having the second light wavelength spectrum to produce a left image; wherein the first image engine is illuminated with light of the first light wavelength spectrum by a first narrowband light source unit, and the second image engine is illuminated with light of the second light wavelength spectrum by a second narrowband light source unit; wherein the processed right image data and the processed left image data are sequentially delivered to the first image engine and to the second image engine, respectively; and wherein the produced right and left images are viewable with viewing glasses having: a right lens filter which passes light of the first light wavelength spectrum, but blocks light of the second light wavelength spectrum; and a left lens filter which passes light of the second light wavelength spectrum, but blocks light of the first light wavelength spectrum.
