Abstract
A buffer device is used by a compressor/decompressor with block prediction for storing information needed to encode/decode a pixel line. Vector information (e.g., final block prediction vector information and/or partial block prediction vector information) of at least one later pixel group is computed while a current pixel group is being encoded/decoded. The buffer device does not need to store vector information of all pixel groups of one pixel line at the same time. For example, one pixel line is composed of M pixel groups; and when the compressor/decompressor is encoding/decoding the current pixel line, final/partial vector information sets of at most K pixel groups are allowed to be stored in the buffer device simultaneously, where K is a positive integer smaller than M.
