The present invention relates to a method and apparatus for encoding a multi-view video and a method and apparatus for decoding a multi-view video, and more particularly, to a method and apparatus for encoding a multi-view video and a method and apparatus for decoding a multi-view video that can perform encoding and decoding in consideration of global disparity between pictures captured at two different viewpoints to remove spatial redundancy. An embodiment of the invention provides an encoder for compressing data for pictures captured at different viewpoints using global disparity in a multi-view video. The encoder includes: an input unit that receives pictures captured at two or more viewpoints; a reference picture generating unit that generates a new reference picture on the basis of the global disparity between a target picture and a reference picture; and a motion predicting unit that calculates motion vectors of the target picture on the basis of the reference picture. |
