IMAGE ENCODING METHOD, IMAGE DECODING METHOD, AND APPARATUSES AND PROGRAMS THEREOF

摘要

The objective of the invention is to obtain an excellent encoding efficiency in a skipped macroblock mode. For each macroblock that is a partial area constituting a texture image (Tf) comprising the brightness value of each pixel, a skipped macroblock mode is used to perform the encoding of the texture image. At this moment, a single macroblock (Tb) is divided into a plurality of partitions (Tp1, Tp2) in accordance with the partitions (Db1, Db2) of a depth macroblock (Db), which is an area corresponding to the single macroblock (Tb), in a depth map comprising the depth value indicating the distance from the view point of each pixel. Further, a predicted vector is generated for each of the partitions (Tp1, Tp2) and encoded by use of the skipped macroblock mode.
