  • Patent number: 9030540
    Abstract: The present disclosure describes systems and methods for reducing ghosting in a three-dimensional (3-D) image system. According to embodiments of the present disclosure, a 3-D image generation system may comprise a first pixel disposed on a semiconductor element that emits light in a first color spectrum and a second pixel disposed on a semiconductor element that emits light in a second color spectrum. A controller may be coupled to the first pixel and the second pixel. The controller may cause the 3-D image generation system to display a first stereoscopic image using the first color spectrum and a second stereoscopic image using the second color spectrum. A filter may be coupled to at least one of the first pixel and the second pixel, and alter at least one of the first color spectrum and the second color spectrum.

  • Publication number: 20140133021
    Abstract: The present disclosure describes systems and methods for enhancing the brightness characteristics of a three-dimensional (3-D) image viewing apparatus. According to embodiments of the present disclosure, a 3-D image viewing apparatus may comprise a frame, a first lens disposed within the frame and a second lens disposed within the frame. The first lens may transmit light within a blue spectrum, a green spectrum, and a red spectrum at a first pre-determined intensity. The second lens may transmit light within an amber spectrum and an offset spectrum at a second pre-determined intensity. In certain embodiments, the offset spectrum may comprise a violet spectrum.

  • Patent number: 8619132
    Abstract: 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.

  • Publication number: 20090284525
    Abstract: Four primary colors may be used to render anaglyphs with a full color gamut. 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. The first image may be rendered in green and blue primary colors and a third primary color which may be a yellow, orange or red. The second image of the anaglyph may be rendered in a red or far-red primary color. A first color filter for viewing the first image may transmit light with wavelengths shorter than an edge wavelength ?e where ?e may be between about 610 nm and 650 nm. A second color filter for viewing the second image may transmit light with wavelengths longer than the edge wavelength ?e.

  • Publication number: 20090278919
    Abstract: 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.
