Abstract
Stereoscopic images are subsampled and placed in a “checkerboard” pattern in an image. The image is encoded in a monoscopic video format. The monoscopic video is transmitted to a device where the “checkerboard” is decoded. Portions of the checkerboard (e.g., “black” portions) are used to reconstruct one of the stereoscopic images and the other portion of the checkerboard (e.g., “white” portions) are used to reconstruct the other image. The subsamples are, for example, taken from the image in a location coincident to the checkerboard position in which the subsamples are encoded.
