摘要： A multiple path stereoscopic projection system is disclosed. The system comprises a polarizing splitting element configured to receive image light energy and split the image light energy received into a primary path and a secondary path, a reflector in the secondary path, and a polarization modulator or polarization modulator arrangement positioned in the primary path and configured to modulate the primary path of light energy. A polarization modulator may be included within the secondary path, a retarder may be used, and optional devices that may be successfully employed in the system include elements to substantially optically superimpose light energy transmission between paths and cleanup polarizers. The projection system can enhance the brightness of stereoscopic images perceived by a viewer. Static polarizer dual projection implementations free of polarization modulators are also provided.

The image data includes a series of left compressed images and a series of right compressed images, the right compressed images and left compressed images compressed using a compression function. The method includes receiving the frames of compressed image data via a medium configured to transmit images in single frame format, and performing an expansion function on frames of compressed image data, the expansion function configured to select pixels from the series of left compressed images and series of right compressed images to produce replacement pixels to form a substantially decompressed set of stereo image pairs. Additionally, a system for receiving stereo pairs, multiplexing the stereo pairs for transmission across a medium including single frame formatting, and demultiplexing received data into altered stereo pairs is provided.

摘要： A segmented polarizing device may be a polarizing modulator which may include strips of switching polarizer material. The switching polarizer material may be used to switch individual segments of the polarizing modulator at a time. In such devices, the polarizing modulator may be one or more liquid crystal cells (LC cell). As the LC modulation panel of a display refreshes an image from top to bottom, changing from left eye content to right eye content, the polarization of a corresponding part of a scrolling polarizing screen may change along with the display.

The processor is further configured to remove an amount of actual image ghost artifacts leaking from a projected left eye image into a projected right eye image and vice versa. The processor is also configured to compute ghost compensation quantities for each of a plurality of zones, each zone corresponding to a region on a screen having an expected ghosting profile associated therewith.

摘要： A method and apparatus for encoding or tagging a video frame provides a way to indicate, to a receiver, for example, whether the video content is 3-D content or 2-D content. A method and apparatus for decoding an encoded or tagged video frame provides a way, for a receiver, for example, to determine whether the video content is 3-D content or 2-D content. 3-D video data may be encoded by replacing lines of at least one video frame with a specific color or pattern. When a decoder detects the presence of the colored or patterned lines in an image frame, it may interpret them as an indicator that 3-D video data is present.
