METHOD AND APPARATUS FOR LOW-BANDWIDTH CONTENT-PRESER VING ENCODING OF STEREOSCOPIC 3D IMAGES

摘要

A method and apparatus are described including accepting a first and a second stereoscopic eye frame line image, determining a coarse image shift between the first stereoscopic eye frame line image and the second stereoscopic eye frame line image, determining a fine image shift responsive to the coarse image shift, forwarding one of the first stereoscopic eye frame line image and the second stereoscopic eye frame line image and forwarding data corresponding to the fine image shift and metadata for further processing. Also described are a method and apparatus including receiving a transmitted first full stereoscopic eye frame line image, extracting a difference between a first stereoscopic eye frame line image and a second stereoscopic image, subtracting the extracted difference from the first stereoscopic eye frame line image, storing the second stereoscopic eye frame line image, extracting a shift line value from metadata included in the first full stereoscopic eye frame line image and shifting the second stereoscopic eye frame line image to its original position responsive to the shift value.
