Patent ID: 8179969

Claim:
An encoder for compressing data for pictures captured at different viewpoints using global disparity in a multi-view video, comprising: an input unit configured to receive pictures captured at two or more viewpoints; a reference picture generating unit configured to generate a new reference picture on the basis of global disparity between a target picture and a reference picture; and a motion predicting unit configured to calculate motion vectors of the target picture on the basis of the new reference picture, wherein the reference picture generating unit comprises: a global disparity calculating unit configured to receive the reference picture and calculate a first global disparity between the target picture and the reference picture, and receive a second reference picture and calculate a second global disparity between the second reference picture and the target picture; a reference picture moving unit configured to increase a number of pixels of the reference picture in horizontal and vertical directions by the first global disparity or more and move the reference picture by the first global disparity, and configured to increase the number of pixels of the second reference picture in the horizontal and vertical directions by the second global disparity or more and move the second reference picture by the second global disparity; an edge copy processing unit configured to copy a non-overlapping region between the reference picture and the second reference picture; and a padding processing unit configured to pad vacant pixels of the increased reference picture or the increased second reference picture, which is generated due to the movement of the reference picture or the second reference picture and an increase in the number of pixels by the reference picture moving unit, with values of pixels in the copied region to generate the new reference picture or a new second reference picture.
