Document Type and Number:
WIPO Patent Application WO/2007/034918
Kind Code:
A1
Abstract:
A macro block size decision unit (1) decides a size of a macro block in a frame unit. A
macro block division unit (2) divides an input image into macro blocks of the size
decided by the macro block size decision unit (1). A macro block encoding unit
(3) decided an encoding mode for each of the macro blocks into which division is
made by the macro block division unit (2) and encodes a pixel value in the macro block
by the decided encoding mode.
