摘要
A variable length encoder 23 multiplexes hint information into an entire region bitstream, the hint information including motion vector limitation information indicating a maximum range in which a search for a motion vector can be performed, GOP size limitation information indicating a GOP size which is the number of pictures belonging to a GOP, and reference configuration specification information indicating a picture to be referred to at the time of decoding each picture belonging to the GOP. As a result, a bitstream of the entire region which is suitable for efficient generation, with a low operation amount, of a bitstream of a partial region can be generated without causing a reduction in the compression efficiency of the bitstream of the entire region.
