Computer holographic stereogram (CHS) is useful for holographic 3D TV because it is constructed from the multi camera horizontal viewpoint plane images and is compatible to the multi holographic stereogram image. Each hologram is recorded as a slit hologram (element hologram) but total viewing area and the number of the element holograms have been limited to some extent by the size and the resolution points of LCD panel. Therefore we used two LCDs for making CHS and deposited them horizontally and increased the viewing points to two times and extend the display area to satisfy the binocular parallax. We considered how viewing area becomes extended. We consider how we could improve the characteriostics of the images of CHS. We got moving images with this system using web-camera and considered the real time calculation about the hologram 3D-TV.
