  • Patent number: 6937757
    Abstract: An extended colorspace which has a higher accuracy and a wider gamut than sRGB color space is disclosed. The extended color space includes an alpha channel which defines the translucency of the color image. The alpha channel is different from known alpha channels in that the inventive alpha channel can represent “super transparent” and “super opaque” values by allowing the alpha parameter (?) to be greater than 1 and less than 0. A data structure for storing the extended colorspace information has three fields, a sign field, an integer field and a decimal field. The sign field defines whether an integer is negative or positive. The integer field defines the integer, wherein the integer defines the super or under saturated values for color and alpha components. The decimal field defines the fine detailed information for the value of the color and alpha components.

  • Patent number: 6906860
    Abstract: The present invention provides an immersive rear projection display capable of providing aspect ratios of 2.66:1 or 4:1, or even greater. This allows viewers to be “immersed” in the images being displayed because the images can encompass both the direct and the peripheral views of a viewer. In one implementation, the immersive rear projection display includes two or more electronic projectors (e.g., three) that are positioned behind a curved translucent display screen. The electronic projectors project respective display images adjacent each other onto the display screen.

  • Patent number: 6856445
    Abstract: A microelectrical mechanical system (MEMS) optical raster display system includes a microelectrical mechanical system (MEMS) device that supports a reflective surface and tilts it in first and second transverse directions. The reflective surface is positioned to receive modulated light from a light source and to direct reflected light toward an image surface, such as a display screen, in a raster scan pattern. The raster scanning of the light is coordinated with the modulation of the light to form a display image on the display screen. In one implementation, the system includes multiple modulated light sources that each direct modulated light toward the reflective surface. The light sources are positioned so that the reflective surface reflects modulated light from each light source to a separate region of the display screen, thereby forming plural contiguous, generally non-overlapping, raster scan patterns.

  • Publication number: 20040246265
    Abstract: A color display (i.e., multicolor computer display) employs four additive primary colors, namely, red, green, and blue and an additional cyan-based color referred to as “supercyan.” The primary color supercyan corresponds to light with a wavelength of about 500 nm and functions to extend the color gamut of a color display significantly beyond the green-blue axis of conventional color displays.

  • Publication number: 20040233498
    Abstract: A MEMS optical display system includes an illumination source for providing illumination light, a collimating lens for receiving the illumination light and forming from it collimated illumination light, and a converging microlens array having an array of lenslets that converge the collimated illumination light. The converging microlens array directs the illumination light to a microelectrical mechanical system (MEMS) optical modulator. The MEMS optical modulator includes, for example, a planar substrate through which multiple pixel apertures extend and multiple MEMS actuators that support and selectively position MEMS shutters over the apertures. A MEMS actuator and MEMS shutter, together with a corresponding aperture, correspond to pixel. The light from the converging microlens array is focused through the apertures and is selectively modulated according to the positioning of the MEMS shutters by the MEMS actuators, thereby to impart image information on the illumination light.

  • Patent number: 6806856
    Abstract: A color filter cross-talk compensator is provided for a multi-color reflective display system having a controllable display cell with multiple adjacent color filters that transmit generally different color components with overlaps between them, ambient light being transmitted into the display cell and reflected back through it. The color filter cross-talk compensator receives image data that correspond to a display image to be rendered and generates cross-talk compensated color component drive signals that are delivered to the display cell (e.g., LCD). The cross-talk compensated color component drive signals compensate for the overlapping color components transmitted by the color filters for the different color components. A color filter cross-talk compensation method is also provided.

  • Patent number: 6795147
    Abstract: A transmissive display system with a controllable display cell, such as a liquid crystal display cell, includes a pair of generally non-absorptive, high reflectance, low transmittance optical layers positioned opposite each other across the cell to provide improved image contrast. In one implementation, non-absorptive, high reflectance, low transmittance optical layers may be formed by dielectric coatings on inner surfaces of generally transmissive plates facing the display cell.

  • Publication number: 20030222849
    Abstract: A remote electronic projection display control system and method are associated with an electronic projector for projecting an image onto a display screen. With regard to the system, a narrow-beam visible light pointer, such as a laser pointer, is operable by a user to direct narrow-beam visible light to the display screen. A multi-pixel light sensor or camera is positioned to receive from the display screen the narrow-beam visible light that is directed there. A controller receives from the multi-pixel light sensor a signal corresponding to the narrow-beam visible light directed to the display screen. The controller correlates the narrow-beam visible light with a display screen location and generates a control signal based upon the display screen location. For example, the user may activate a graphical user interface control rendered on the display screen by pressing a light-controlling button that modulates the narrow-beam visible light.

The converging microlens array directs the illumination light an array of pixel apertures in an aperture plate to a microelectrical mechanical reflector array positioned opposite the aperture plate. The microelectrical mechanical reflector array includes an array of microelectrical mechanical actuators that support reflectors in alignment with the array of pixel apertures. The array of microelectrical mechanical actuators orient the reflectors selectively to direct the illumination light back through the pixel apertures (to form part of a display image) or against the aperture plate (to be blocked).

  • Publication number: 20020176628
    Abstract: A document digitizing method digitizes and automatically indexes documents in printed form. The method includes optically scanning the document, forming and storing a digitized image file from the optically scanned document, optically recognizing characters in the optically scanned document, and forming and storing a text file of the optically recognized characters in document. A retrieval method for retrieving the digitized image file for a document includes searching the text files to identify any having a selected text string and providing access to the digitized image files that correspond to those text files. The digital image file and the text file together represent a digitized document data structure that combines a digital image of a document with a text file of optically recognized characters in the digital image.

  • Patent number: 5781668
    Abstract: A method and apparatus for improving the quality of images captured by inexpensive scanning devices is described. After an initial scan of the image to be captured is performed, at least two additional scans are performed, one at an exposure level much greater than that used in the first scan and one at an exposure level much lower than that used in the first scan. After all three scans are complete, a composite stored image is formed using the gray scale values generated by the overexposed scan for darker areas of the image, the gray scale level generated by the underexposed scan for the lighter portions of the image, and, for those areas between the extremes, using the gray scale levels produced by the first scan. An apparatus is also described for performing these scans and selecting and combining the requisite data.
