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.

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.

Abstract: A first embodiment of the invention permits an extension of battery life through detection of the display synchronization signals of a computer and a power management system. The power management system also eliminates need for batteries through use of a 5V power source from pin 9 of the VGA port. A second embodiment improves the ease of use and the utility of the 3D system through removable glasses with improvements over the previous design. These embodiments have improved manufacturability through the use of design that is tolerant of poor quality, low cost components with low electrical tolerances.
