Abstract: An intelligent system and process for producing and displaying stereoscopically-multiplexed images of either real or synthetic 3-D objects, for use in realistic stereoscopic viewing thereof. The system comprises a subsystem for acquiring parameters specifying the viewing process of a viewer positioned relative to a display surface associated with a stereoscopic display subsystem. A computer-based subsystem is provided for producing stereoscopically-multiplexed images of either the real or synthetic 3-D objects, using the acquired parameters. The stereoscopically-multiplexed images are on the display surface, for use in realistic stereoscopic viewing of either the real or synthetic 3-D objects, by the viewer.

Abstract: In a method of expanding a compressed color image, in units of blocks each consisting of a plurality of pixels, to lightness information and chromaticity information representing a block, original lightness information is decoded on the basis of the compressed lightness information in units of blocks, and chromaticity information of each pixel in the block is decoded in accordance with a distribution and gradient of the decoded lightness information value.
