Abstract
A stereoscopic video coding device inputs therein a reference viewpoint video and a left viewpoint video, as well as a reference viewpoint depth map and a left viewpoint depth map which are maps showing information on depth values of the respective viewpoint videos. A depth map synthesis unit of the stereoscopic video coding device creates a left synthesized depth map at an intermediate viewpoint from the two depth maps. A projected video prediction unit of the stereoscopic video coding device extracts, from the left viewpoint video, a pixel in a pixel area to constitute an occlusion hole when the reference viewpoint video is projected to another viewpoint and creates a left residual video. The stereoscopic video coding device encodes and transmits each of the reference viewpoint video, the left synthesized depth map, and the left residual video.
