Abstract
A method, medium, and apparatus predicting direct mode motion of a multi-angle moving picture on a temporal and spatial basis. The method may include locating a block to which a co-located block of a block for which coding is sought makes reference with a motion vector, calculating a forward motion vector and a backward motion vector by making reference to pictures of an adjacent camera that exists in a direction parallel to a direction corresponding to the motion vector when a reference picture is not taken by the same camera as the picture to which the block for which coding is sought belongs, and calculating forward and backward reference blocks of the block for which coding is sought by applying weights to the calculated motion vectors. Therefore, the moving picture can be coded/decoded by locating motion vectors of previous and subsequent pictures without predicting motion, reducing calculation and performance time.
