  • Publication number: 20140306958
    Abstract: A stereoscopic rendering system is disclosed that comprises a depth buffer having at least two depth buffer portions respectively corresponding to different views of a scene, the depth buffer arranged to store depth values indicative of the depth of pixels in a scene, and the depth buffer portions having different associated depth value ranges so that the different depth buffer portions are distinguishable from each other. The system also includes an image buffer arranged to store information indicative of an image to be displayed. The system is arranged to apply a different depth test for each view of the scene such that only pixels of the view that spatially correspond to the depth buffer portion associated with the view are rendered to the image buffer. The image rendered into the image buffer comprises image portions respectively spatially corresponding to the different depth buffer portions and the different views of the scene.

  • Patent number: 7035451
    Abstract: A method of creating a depth map including the steps of assigning a depth to at least one pixel or portion of an image, determining relative location and image characteristics for each at least one pixel or portion of the image, utilizing the depth(s), image characteristics and respective location to determine an algorithm to ascertain depth characteristics as a function relative location and image characteristics, utilizing said algorithm to calculate a depth characteristic for each pixel or portion of the image, wherein the depth characteristics form a depth map for the image. In a second phase of processing the said depth maps form key frames for the generation of depth maps for non-key frames using relative location, image characteristics and distance to key frame(s).
