20080198459 | CONJUGATE OPTICS PROJECTION DISPLAY SYSTEM AND METHOD HAVING IMPROVED RESOLUTION - A conjugate optics projection display system includes a beam splitter positioned for viewing an object through the beam splitter and a projector positioned to project an image through the beam splitter, where the projector has a focal plane distance. A retroreflector is optically coupled to the beam splitter and positioned at a distance from the projector, where the distance is less than the focal plane distance of the projector. The retroreflector may include retroreflective elements having a size effective to match or exceed optical resolution requirements of the display system. | 08-21-2008 |
20100253846 | IMAGE ACQUISITION AND DISPLAY SYSTEM AND METHOD USING INFORMATION DERIVED FROM AN AREA OF INTEREST IN A VIDEO IMAGE IMPLEMENTING SYSTEM SYNCHRONIZED BRIGHTNESS CONTROL AND USE OF METADATA - Method and apparatus for preparing and displaying images uses image characteristics of an area of interest of images to optimize or otherwise determine image characteristics of the entire image to be displayed. The area of interest information may be used in computing an SSBC profile for the area of interest, and the SSBC profile may be used to adjust the image signal to provide an image in which the image characteristics, e.g., are optimized for the image at the area of interest. The image characteristics and/or SSBC profile information may be provided as metadata included in a video signal data stream. The area of interest may be selected where the image is obtained, where the image is shown or elsewhere, e.g., in an image storage device, image player, etc. | 10-07-2010 |
20110122272 | Apparatus and method for preparing, storing, transmitting and displaying images - An imaging and display apparatus for passive displays evaluates the illumination of an input scene and incorporates data representative of such input scene within a transfer media. The transfer media may be a broadcast or transmission of image data, illumination data and gamma information that can be received by a display system, which includes a passive display illuminated by incident light, to display images while adjusting the incident light and/or gamma based on the received data. The transfer media may be a storage medium storing image data, illumination data and gamma information for delivery to a passive display system. The data controls the optical characteristics of the illumination source for the passive display and the gamma and tends to minimize energy requirements, to maximize contrast or shades of gray in the displayed image, and to optimize light source operation for color fidelity. The data provided the media and/or display as a video signal, modulated video signal, s-video signal, digital signal, or other signal that can be used by a passive display system to display images. | 05-26-2011 |
20110241978 | OPTICAL DISPLAY SYSTEM AND METHOD, ACTIVE AND PASSIVE DITHERING USING BIREFRINGENCE, COLOR IMAGE SUPERPOSITIONING AND DISPLAY ENHANCEMENT WITH PHASE COORDINATED POLARIZATION SWITCHING - A display apparatus includes a passive display, a light source, and a video signal input, in operation in response to a video signal the passive display modulates light from the light source to provide an image, and the intensity of the light source is controlled by the video signal. | 10-06-2011 |
20110310131 | APPARATUS AND METHOD TO ENHANCE LEGIBILITY OF IMAGES SHOWN ON A DISPLAY - A display system and method for improving legibility of images viewed on a passive display in a bright environment, including apparatus and method for increasing or maintaining the range of grey levels for the image as viewed on the display and decreasing the number of grey levels used in that range. | 12-22-2011 |
20130069998 | APPARATUS AND METHOD FOR PREPARING, STORING, TRANSMITTING AND DISPLAYING IMAGES - An imaging and display apparatus for passive displays evaluates the illumination of an input scene and incorporates data representative of such input scene within a transfer media. The transfer media may be a storage medium storing image data, illumination data and gamma information for delivery to a passive display system. The data controls the optical characteristics of the illumination source for the passive display and the gamma and tends to minimize energy requirements, to maximize contrast or shades of gray in the displayed image, and to optimize light source operation for color fidelity. The data provided the media and/or display as a video signal, modulated video signal, s-video signal, digital signal, or other signal that can be used by a passive display system to display images. | 03-21-2013 |
20130155085 | APPARATUS AND METHOD FOR PREPARING, STORING, TRANSMITTING AND DISPLAYING IMAGES - An imaging and display apparatus for passive displays evaluates the illumination of an input scene and incorporates data representative of such input scene within a transfer media. The transfer media may be a broadcast or transmission of image data, illumination data and gamma information that can be received by a display system, which includes a passive display illuminated by incident light, to display images while adjusting the incident light and/or gamma based on the received data to reduce energy requirements, to increase contrast or shades of gray in the displayed image, and to optimize light source operation for color fidelity.
