摘要

An image encoding device comprises a conversion means (11) for converting an image block, an entropy encoding means (12) for entropy encoding image block data converted by the conversion means (11), a PCM encoding means (13) for PCM encoding an image block, a multiplex-data selection means (14) for selecting either the data output from the entropy encoding means (12) or the data output from the PCM encoding means (13) in blocks the size of which is set externally, and a multiplexing means (15) for embedding a PCM header in a bitstream in blocks the size of which is set externally.
