An intra prediction coding direction value of the searched macroblock is determined as an intra prediction coding direction value of the current macroblock. The current macroblock is coded/decoded through the determined intra prediction coding direction value. The coding efficiency can be increased by reducing a coding amount by omitting a process of obtaining an unnecessary disparity value by using a different-view intra prediction coding direction as a current-view intra prediction coding direction. The coding efficiency can be increased by reducing a coding amount by differentially coding a similar disparity vector. The reliability can be increased through an accurate disparity using multiples of 8 rather than 16, in motion skip for sharing the format of a macroblock. | 01-15-2009 |
