Abstract
Methods and apparatus for performing stereoscopic image encoding and decoding are described. Left and right eye images are generated. Image difference information is generated, e.g., a set of pixel values resulting from XORing the pixel values of the left and right eye images. One of the left and right eye images is compressed along with the difference map. The compressed image and compressed difference map is stored and/or transmitted. Stereoscopic images are generated by decompressing and using the received compressed image and compressed difference information. Prior to generation of the difference map the left and right eye images may be subject to a transposition operation to minimize the differences between the images and thus the size of the difference map. When transposition is applied, transposition information is stored and communicated in addition to the compressed image data so that the transposition can be reversed during the stereoscopic image generation process.
