Method and apparatus for block-based compression of light-field images

摘要

Light-field images may be preprocessed by a preprocessing module into a format that is compatible with the blocking scheme of a block-based compression technique, for example JPEG. The compression technique is then used to compress the preprocessed light-field images. The light-field preprocessing module reshapes the angular data in a captured light-field image into shapes compatible with the blocking scheme of the compression technique so that blocking artifacts of block-based compression are not introduced in the final compressed image. Embodiments may produce compressed 2D images for which no specific light-field image viewer is needed to preview the full lightfield image. Full light-field information is contained in one compressed 2D image.
