Abstract
A prediction vector generation device generating a prediction vector of a disparity vector of a target block in a non-base viewpoint image includes a conversion pixel determination unit determining at least one pixel position in a depth block corresponding to the target block in a depth map corresponding to the non-base viewpoint image, a disparity vector conversion unit calculating a representative value of a depth value of the at least one pixel position determined by the conversion pixel determination unit and converting the representative value into a disparity vector, and a prediction vector determination unit generating the prediction vector of the disparity vector of the target block by using the disparity vector generated by the disparity vector conversion unit. This prediction vector generation device provides good encoding efficiency and suppresses increases in the amount of computation.
