<P>PROBLEM TO BE SOLVED: To provide an encoding device, a program and a method thereof which can improve encoding efficiency even if motion compensation prediction is performed per conventional macroblock and can perform transcoding from a conventional method of capable of dividing macroblock into a method of not capable of dividing macroblock, without changing an encoding system such as MPEG-1 or MPEG-2 which have already been completely standardized. <P>SOLUTION: The encoding device 1 performs motion compensation prediction per block of an original image included in a dynamic image and compression-encodes the dynamic image. The device 1 is provided with a macroblock motion vector retrieving section 3, a macroblock dividing section 5, a divided block accumulating/successively outputing section 7, a divided block motion vector retrieval 9, a reference image accumulating section 11, a motion vector accumulating section 13, a macroblock motion compensating section 15, a motion compensation macroblock accumulating section 17, and a macroblock image comparing section 19. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
