摘要

According to the present invention, a tile division unit (1) divides an input image into tiles and outputs the tiles, each tile being a rectangular region having a designated size. A block division unit (10) of a division video encoding unit (3) divides the tile output from the tile division unit (1) into encoding blocks having a predetermined size, and hierarchically divides the encoding block until the number of hierarchies reaches the upper limit hierarchical number determined by an encoding control unit (2).
