    摘要： A method and apparatus for selectively blurring parts of an image set according to differences in disparity between successive images. As a result, the one-dimensional ringing edge artifacts, intrinsic to autostereoscopic displays, are hidden, thereby improving the perceived image quality of a multi-view autostereoscopic image. The method may involve detecting regions of disparity between adjacent views, and then blurring those regions by weighted local pixel averaging. The relationship between the blur radius and the disparity is preferentially non-linear to maintain sharpness of low disparity regions.

    摘要： Disclosed is a light guiding valve apparatus including at least one transparent stepped waveguide optical valve for providing large area collimated illumination from localized light sources, and at least one further illumination source. A stepped waveguide may be a stepped structure, where the steps include extraction features hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays as well as improved 2D display functionality. Light from a separate illumination source may pass through the transparent stepped waveguide optical valve to provide at least one further additional illumination function.

    摘要： Disclosed is a light guiding valve apparatus comprising an optical valve, a two dimensional light source array and a focusing optic for providing large area collimated illumination from localized light sources. A stepped waveguide may be a stepped structure, in which the steps may be extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. A two dimensional array of viewing windows may be produced. Such controlled illumination may provide for efficient, multi-user autostereoscopic displays with wide viewing freedom and low cross talk and near-eye displays that are substantially transparent.

    摘要： Projection systems and methods for providing stereoscopic images viewed through passive polarizing eyewear. The systems relate to projectors that create left and right eye images simultaneously and often as side-by-side images on the image modulator. The systems act to superimpose the spatially separated images on a projection screen with alternate polarization states. The embodiments are best suited to liquid crystal polarization based projection systems and use advanced polarization control.

    摘要： The present application describes color management architecture for a three-panel projection system that utilizes color selective polarization filters (CSPF) and polarizing beam splitting elements (1104,1106,11089). An exemplary embodiment describes a color management architecture with a dichroic input beam splitter (1302) and three polarizing beam splitters (1104,1106,1108). An output polarizing beam splitter is used as an analyzer. The color management system architecture can isolate any color channel from those remaining whose separation and combination are then carried out by a single beamsplitting element. The disclosed embodiments also provide an improvement in the ANSI contrast. In some embodiments, an achromatic quarter-wave plate is used in combination with a color filter to block the light reflected from projection optics.

    摘要： Disclosed is an imaging directional backlight polarization recovery apparatus including an imaging directional backlight with at least a polarization sensitive reflection component with optional polarization transformation and redirection elements. Viewing windows may be formed through imaging individual light sources and hence defines the relative positions of system elements and ray paths. The base imaging directional backlight systems provide substantially unpolarized light primarily for the illumination of liquid crystal displays (LCDs) resulting in at least 50% loss in light output when using a conventional sheet polarizer as input to the display. The invention herein introduces a polarization sensitive reflecting element to separate desired and undesired polarization states for the purposes of transformation and redirection of the reflected light for usable illumination. Polarization transformation and redirection can be provided by additional components such as retarder films and specular mirror surfaces.
