  • Patent number: 7224411
    Abstract: Apparatus and techniques for enhancing characteristics of electronic projection systems are detailed. Included among the techniques are both superimposition of sub-images and tiling of superimposed images, the combination of which can be advantageous in improving resolution of projected images. Pre-modulators and polarizing beam splitters also may be used as parts of the innovative systems.

    Date of Patent: May 29, 2007
    Assignee: Imax Corporation
    Inventors: Michael A. Gibbon, Samuel Z. Zhou, Graham H. Moss, Dermot J. Quinn, Steven Wilding, Brian Eckersley, Sean Adkins, Sergei G. Anikitchev, Steven Read
  • Patent number: 7224335
    Abstract: A projection system having a controller and a plurality of reflective SLMs operatively coupled to the controller to receive image data from the controller. The reflective SLMs arc aligned in series to receive light form a light source and to reflect imaging light correlated to the image data.

  • Publication number: 20060007406
    Abstract: The present invention discloses systems, equipment and methods that allow the improved adjustment of color in projection displays. Equipment, systems and methods are disclosed for matching the color balance of each display including the color of the display primaries and further equipment, systems and methods are disclosed for the correction of a field dependant color variation across the field of an SLM based projector.

  • Patent number: 6751006
    Abstract: Addressed herein are techniques and equipment for pre-processing digital images to be superimposed for display. Filtering, re-sampling, and decimation are variously used to process images and sub-images to produce to-be-superimposed images. One of the described techniques is designed primarily (although not necessarily exclusively) for computational efficiency, while the other sacrifices some computational efficiency for higher quality of output images.

  • Patent number: 6697573
    Abstract: Systems and techniques relating to creating motion pictures are described. Included as part of the system are cameras incorporating two taking lenses, one of which images onto film through a shutter and the other of which images onto a digital sensor.

  • Publication number: 20030190072
    Abstract: A method and apparatus for accurately computing parallax information as captured by imagery of a scene. The method computes the parallax information of each point in an image by computing the parallax within windows that are offset with respect to the point for which the parallax is being computed. Additionally, parallax computations are performed over multiple frames of imagery to ensure accuracy of the parallax computation and to facilitate correction of occluded imagery.

  • Patent number: 5975720
    Abstract: A color changer for use with a wide angle light source which includes a frame, a plurality of planar dichroic filter strips mounted on the frame and aligned substantially parallel to each other. The filter strips have identical predetermined optical filtering characteristics with first and second sets of the filter strips movable along a common axis so as to vary the gap between them and at least alternate ones of the filter strips in each of the first and second sets set at an angle such that, when the color changer is positioned in a beam of light transmitted from the wide angle light source, a substantially constant angle of incidence is maintained with respect to light from the light source incident on the alternate ones of the dichroic filter strips.
