Patent ID: 11039168

Abstract:
A method for compressing data comprising a stereoscopic pair of images which provide parallax, when viewed by left and right eyes of an observer, involves generating (S31) the stereoscopic pair of images, each image comprising a plurality of display elements. A disparity value (S32) is generated indicating an amount by which a location of each display element in a first image of the stereoscopic pair of images is displaced compared to a displaced location of the same display element in a second image of the stereoscopic pair of images, such that a plurality of disparity values is generated. The number of different disparity values present in the plurality of disparity values is then reduced (S34) to produce a reduced set of different disparity values. A particular disparity value is determined from the reduced set of different disparity values to be associated with each of the locations and/or displaced locations of the display elements, and compressed data (S35) is generated comprising the first image of the stereoscopic pair of images, the reduced set of different disparity values, and information indicating the particular disparity value associated with each of the locations and/or displaced locations to be used to regenerate a regenerated second image of the stereoscopic pair of images corresponding to the second image.
