Abstract
A method for multiplexing a stream of stereoscopic image source data into a series of left images and a series of right images combinable to form a series of stereoscopic images, both the stereoscopic image source data and series of left images and series of right images conceptually defined to be within frames. The method includes compressing stereoscopic image source data at varying levels across the frame, thereby forming left images and right images, and providing a series of single frames divided into portions, each single frame containing one right image in a first portion and one left image in a second portion. Alternately, single frames may contain two right images in a first two portions of each single frame and two left images in a second two portions of each single frame, wherein each set of right and left images may be processed differently. Multiplexing processes such as staggering, alternating, filtering, variable scaling, and sharpening from original, uncompressed right and left images may be employed.
