  • Patent number: 7817166
    Abstract: An operating system level windowing system provides for the reliable display of multiple translucent windows. Incorporating stereo object processing within the windowing system itself (rather than at the application level), permits the windowing system to ensure that stereo content is reliably displayed (e.g., via use of blue-line technology) regardless of whether a window within which stereo content is displayed is occluded or overlapped by another window.

  • Patent number: 7538768
    Abstract: An image display device capable of displaying an images on right and left image display elements (26I, and 26R) by receiving right and left image signals for displaying three-dimensional images which are fed alternately in a field sequence manner. The degree of influence on the viewer is operated by measuring the parallax value of the right and left image signals fed to the right and left image display elements (26L, and 26R) by a 3D protecting means (14), and it is judged whether or not the operated degree of influence reaches a reference value. If the operated degree of influence reaches the reference value, the degree of influence of the 3D image on the viewer is reduced by selectively displaying the result of the judgment on the right and left image display elements (26L, and 26R), so that the image can be viewed in a consistently suitable manner.

  • Publication number: 20090115783
    Abstract: A 3D viewing system captures offset images from off-axis camera perspectives inclined to a normal of base plane of a scene that includes one or more objects projecting from the base plane. The offset images, which take a planar form, are displayed from a display surface at an off-axis viewing perspective that is inclined to a normal of the display surface similar to the inclination of the off-axis camera perspective to the normal of the base plane. The offset images undergo a distortion to counteract a keystone distortion associated with the off-axis viewing perspective. The base plane of the scene is oriented parallel to the display surface, and the objects projecting from the base plane appear to project from the display surface.

    Abstract: Shaped glasses have curved surface lenses and spectrally complementary filters disposed on the curved surface lenses configured to compensate for wavelength shifts occurring due to viewing angles and other sources. The spectrally complementary filters include guard bands to prevent crosstalk between spectrally complementary portions of a 3D image viewed through the shaped glasses. In one embodiment, the spectrally complementary filters are disposed on the curved lenses with increasing layer thickness towards edges of the lenses. The projected complementary images may also be pre-shifted to compensate for subsequent wavelength shifts occurring while viewing the images.
