  • Patent number: 7215357
    Abstract: A line blanker system for converting a stereoscopic image into a line-blanked stereoscopic image suitable for stereoscopic viewing on a standard non-interleaved display device is provided. The system includes a method for controlling the line blanker. According to the invention, one can enable and disable the line blanker, identify the first line of the image being processed and determine whether the first line is for viewing by the left eye or the right eye of a viewer. In addition, the invention includes a line doubler. The line doubler provides enhanced brightness and resolution by replacing the blanked line with a double of the line immediately adjacent to the blanked line.

  • Patent number: 6904122
    Abstract: The present invention provides a means to augment or upgrade a traditional single beam 2D x-ray system to produce 3D stereoscopic output. The system utilizes the cross-sectional beam divergence of a single source x-ray unit to generate perspective information. This is achieved by scanning the object twice where the object is shifted parallel to the cross-sectional beam plane between scans. The resulting two scans can be displayed on a 3D stereoscopic viewing system to produce a 3D stereoscopic representation of the object thus revealing all three-depth dimensions. The invention includes a method of converting a 2D x-ray system to a 3D x-ray system requiring no changes to an x-ray generation portion, optics portion or sensing system portion of said 2D x-ray system. The method includes coupling a 3D stereoscopic image processor to a 2D processor and installing a mechanical shift system and coupling said shift system to said 3D stereoscopic image processor and a object carrying device.

  • Patent number: 6765568
    Abstract: The preferred embodiment addresses the problem of delivering stereoscopic media in electronic form (images, videos, animations, object models, etc.). First, it provides a single format with independent right and left channels to represent the stereoscopic media. Second, it provides a means of displaying stereoscopic media inside a movable windowed area while eliminating pseudostereo conditions during movement. Third, it provides automatic and manual optimization adjustments (parallax shift adjustment, brightness control, color adjustment, and cross-talk reduction) to the stereoscopic media based on viewing hardware, monitor size, and media content for optimal viewing quality. Fourth, it provides seamless support for monoscopic (2D) viewing modes allowing delivery of said stereoscopic media in a normal 2D viewing mode.

  • Publication number: 20020163574
    Abstract: Limiting or eliminating external light to the peripheral vision areas of the user reduces flicker. The aperture of the liquid crystal filter is dynamically adjusted to maintain a particular aspect ratio to match the image displayed by computers and television sets. The size of the aperture of the liquid crystal filter is user adjustable through a mechanical or electrical aperture system. The size of the aperture of the liquid crystal filter is automatically adjustable through an electrical aperture control system and a proximity system. The aperture is adjusted based on the sensed distance between the user and the display medium. The location of the aperture is automatically adjustable through an electrical aperture control system and head orientation system. The aperture location in front of the LC shutter is moved vertically or horizontally depending on the pointing direction of the users head with respect to the display system.

  • Publication number: 20020141635
    Abstract: Methods and systems are described for zooming a stereoscopic image. The image is typically divided into a plurality of regions. A value is defined for each region, such as a minimum parallax value or a function of the minimum parallax value. A zoom area is selected having a boundary intersecting at least one of the regions. The values within the intersected regions are compared to determine a preferred value based on predetermined criteria. The zoom area is shifted by the preferred value or a function of the preferred value.
