ABSTRACT:
An image encoding apparatus comprises first processing means for determining whether or not each bit in a bit plane of a code block should be processed in a first pass, and second processing means for determining whether or not each bit in a bit plane of a code block should be processed in a second pass which is other than the first pass. The first processing means and the second processing means operate in parallel for the same bit plane of the same code block. The first pass is a SIG (significance propagation) pass used in the processing of JPEG-2000 image compression/decompression scheme, for example, and the second pass is a REF (magnitude refinement) pass used in the JPEG-2000 processing.
