The device includes an illumination source configured to transmit light energy in multiple sections or segments, each section or segment having an optical attribute associated therewith, such as a color (red, green, blue). The illumination source may include light emitting diodes or light projected through a “color wheel,” and light energy is polarized by the illumination source. At least two adjacent sections of the have identical optical attributes, such as identical colors, and different perspective views associated therewith.

20090278919 | HIGH-FIDELITY PRINTED ANAGLYPHS AND VIEWING FILTERS - Four primary colors provide a wide color gamut in the anaglyph images. Primary colors with narrow spectral distributions allow the first and second images in an anaglyph to be viewed using colored filter glasses. In print media, primary colors with narrow spectral distributions are provided by fluorescent inks and incident light with narrow spectral distributions. Incident light with narrow spectral distributions may cooperate with broad adsorption spectra of inks to produce reflected light with narrow spectral distributions from printed anaglyphs. Viewing filters for anaglyphs comprised of narrow spectral distributions may have broad, overlapping transmission spectra and utilize adsorption dyes or pigments. | 11-12-2009 |
20090284586 | WIDE COLOR GAMUT ANAGLYPHS - Four primary colors may be used to render anaglyphs with wide color gamuts. The first image of a stereoscopic pair may be rendered in three primary colors while the second image of a stereoscopic pair may be rendered in a fourth primary color. Retinal rivalry may be avoided in an anaglyph by balancing the brightness contrasts of the first and second images for like subject matter. The retinal rivalry may be measured and controlled in anaglyphs by selecting values of a retinal rivalry color coordinate. | 11-19-2009 |

20110102563 | MULTI-SPECTRAL STEREOGRAPHIC DISPLAY SYSTEM - A multi-spectral stereoscopic display system is disclosed. A left-eye image may be presented and viewed via a first set of spectral bands. A right-eye image may be presented and viewed via a second set of spectral bands. The two sets of spectral bands may have low or no overlap with each other. The color balances of the left-eye image and the right-eye image may be almost matching or identical. The left-eye image and the right-eye image may each be a full-color image with neutral color balance, even without modifying the color balance of original image content.

The filter design may lead to an inexpensive viewing apparatus that can be mass-produced using inexpensive glass or polymer substrates. This system does not rely on polarization techniques and may be used with a white or metallic display screen. | 05-05-2011 |
