摘要： An electronic holographic display device includes: a beam emitting device; a plurality of polarizing beam splitters; a plurality of spatial light modulators, each of which is disposed with prescribed distances therebetween and modulates a beam vertically made incident from the corresponding polarizing beam splitter; a magnifying optical system; and a reducing optical system. The magnifying optical system includes a first lens array and a second lens array. The reducing optical system includes a third lens array and a fourth lens array. A distance “a” between the spatial light modulator and the first lens is represented by a=(k+2)f0/(k+1), wherein a ratio “k” is a distance between two adjacent spatial light modulators, to a size of the spatial light modulator, and f0 is a focal point distance of the first lens.

摘要： 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.
