  • Patent number: 6950121
    Abstract: A method and apparatus for providing inexpensive and accurate electrical synchronization between the individual cameras within a 3D or stereoscopic video camera is disclosed. The method and apparatus use a common clock pulse to both cameras and a frame reset pulse generated by one camera to provide a frame reset for the second camera. By using these pulses, it is possible to fully synchronize the two camera, a multiplexer and an RGB encoder to produce a totally in synchronization 3D or stereoscopic video signal without using expensive gen-lock techniques. In addition a method and apparatus for providing mechanical adjustment for the convergence of the horizontal axes of the cameras with a 3D or stereoscopic video camera is explained. It addition, the basic techniques used in the convergence is also shown for achieving an inexpensive and accurate method and apparatus for matching the tilt position of the individual cameras is shown.

  • Patent number: 6943852
    Abstract: The invention is a stereoscopic shutter system having a single liquid crystal (LC) cell. The system may have flexible substrates or non-flexible substrates. The system requires only two electrical conductors to shutter both eyes. The system uses twisted nematic liquid crystal, ferro-electric liquid crystal, pi-cell technology, or other similar shuttering technologies. The system includes only one LC cell, a single large laminated linearly polarizing filter P1, and two smaller linear polarizing analyzers oriented in the P1 and P2 states. The shutters may be bent into a one-dimensional curved shape about the vertical or horizontal axis.

  • Publication number: 20040218269
    Abstract: Because of the numerous possibilities in the capture, transmission, and display of stereoscopic image pairs during 3D format conversion, there are numerous compatibility issues between the various stereoscopic image sources and stereoscopic display systems. A general purpose stereoscopic 3D format conversion system and method is described that eliminates these compatibility issues by providing a system that performs conversion of any stereoscopic image stream within a specified set of 3D formats to any other 3D format within the set. The system also performs numerous other image processing functions that are beneficial for stereoscopic image processing such as image pan, alignment, zoom, crop, keystone correction, video format conversion, scan-rate conversion, and an array of standard 2D image enhancements including brightness, contrast, hue saturation, and sharpness.

  • 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.

  • Patent number: 6529175
    Abstract: The preferred embodiment a stereoscopic LCD shutter glass driver system requires only a total of 3 CMOS integrated circuit chips in order to convert horizontal and vertical sync signals into LCD shutter glass drive signals. A negative charge pump is used increase the LCD drive voltage thereby reducing 3D crosstalk in the image. The video signal input is shown with a passthrough connection intended for direct hook-up to a television or CRT monitor. A first flip flop detects vertical and horizontal sync and is used to drive the charge pump. A stable, predictable field ID signal is produced by the flip flop whose two complimentary outputs act as inputs to a second flip flop chip which produces the drive signals for the LCD shutter glasses. A third flip flop produces a LCD “common” signal that is sent to both LCD shutters. The second flip flop produces a drive signal for each LCD shutter. A field swap between the two shutters is implemented with a switch located at the output of the third flip flop.

  • Publication number: 20020180906
    Abstract: The object of the present invention is to eliminate the flicker of an LCD/Micropol assembly by reducing the excess heat caused by the attachment of the Micropol to the LCD. The present invention solves the problem of LCD flicker caused by excess heating of the LCD/Micropol assembly by reducing the amount of heat transferred to the LCD from the projection lamp. This solution is realized through the use of a special wide-band IR filter that prevents IR radiation from reaching the LCD/Micropol assembly. The IR filter used in the preferred embodiment is based on cholesterol liquid crystal reflectors that are made to reflect IR radiation back into the projection lamp. The excess heat is removed by the projection cooling system and is not transmitted to the LCD display.

  • 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.
