1. An apparatus comprising: an encoder for encoding an image block of a picture corresponding to at least one view of multi-view video content by obtaining motion information for the image block based upon disparity information for a first region of a plurality of regions of an other picture, the other picture corresponding to at least one other view of the multi-view video content, and each region corresponding to less than an entirety of the other picture, wherein each region includes multiple image blocks, each region having been determined based on a similarity among disparity vectors of the multiple image blocks of the region, and wherein the disparity information for the first region includes a regional disparity vector determined from the disparity vectors of the multiple image blocks of the first region.
