ABSTRACT:
An apparatus for processing an input image, represented by an input bit stream including a plurality of first bit sets, is provided. The apparatus includes a device for processing the input bit stream in such a manner that each of the first bit sets is represented by a second bit set with each of the second bit sets having less bits than each of the first bit sets and a selected number of bits in the input bit stream, corresponding to image-related information, being discarded as a result of the encoding. The apparatus is provided with an electronic volatile memory for storing a resulting encoded bit stream and a bit stream analyzer for analyzing the stored encoded bit stream to generate positional signals. The apparatus is further provided with a reconstruction circuit for reconstructing the stored encoded bit stream, by reference to the positional signals. The reconstruction circuit operates in such a manner that, upon outputting an image representation of the reconstructed bit stream, the outputted image includes at least a part of the discarded, image-related information.
