A reality-enhanced autostereoscopic display system is presented. In this system, the viewers who do not wear any special glasses can perceive 3-D images within their hands' reach with little sense of incongruity. The feature of this system is combination of real image generation and parallax presentation. Real image of the display in the back is generated in the air by using Fresnel lenses, which has made it possible to narrow artificial parallax to display 3-D objects in the workspace near the viewer without interfering the viewers' motion. Smaller artificial parallax leads to 3-D perception with more reality and less eyestrain than the conventional 3-D displays. For parallax presentation an mobile filter which plays the role of stereoscpopic goggles is set between the display in the back and the Fresnel lenses and is controlled so that it follows the motion of the viewer to keep on presenting different images to each eye. To present undistorted 3-D space the optical path including refraction by Fresnel lenses is calculated and the image on the screen is updated based on it. Real-time undistorted image presentation to unrestricted eye positions is realized by suing texture mapping technique.

To allow multiple viewers to see the correct perspective and to provide a single viewer with motion parallax cues during head movement, more than two views are needed. Since it is prohibitive to acquire, process, and transmit a continuum of views, it would be preferable to acquire only minimal set of views and to generate intermediate images by using the estimated disparities. For high quality of the generated image, the first, we propose how to generate the intermediate images using multi-resolution and irregular-quadtree decomposition. Irregular-quadtree decomposition is aligned at the object boundary which is the disparity discontinuity. By finding the peak over the absolute values of the high pass filtered output that is applied to the row and column average, the horizontal and vertical dividing locations of the block are computed. The second, regions of occlusion are decided by similarity comparisons among the matched block alternatives, then filled with the pixels of left or right image by the principles we proposed. Finally, the images at arbitrary viewpoints are generated and yielding a 31.1 dB PSNR at middle location between both viewpoints.

The National Institute of Information and Communications Technology (NICT) has experimented using a 1,244 Mbps high-speed burst modem with single carrier QPSK modulation through a bandwidth of 1.1 GHz transponder on the Wideband InterNetworking engineering test and Demonstration Satellite (WINDS). We developed a 16APSK/16QAM-OFDM 3.2 Gbps radio frequency signal direct-processing transmitter and receiver system for even greater broadband transmission. This chapter shows that a 4K UHDTV transmission demonstration experiment using WINDS satellite bent-pipe transponder through a 10 GbE interface was successfully performed by this system.

We aimed to develop a new 3D reconstruction system that provides to realize the 3D space-shared communication over the network. In this paper we would like to introduce our recent result on a 3D model generation research. Multiple eye stereo camera system is basically applied in this research project. The model of an object is reconstructed using the depth images grabbed by the multiple eye cameras from different viewing angles. The reconstructed models of the reference object relative to the multiple views generate the complete 3D model. By using the communication system software, which is called NetUNIVERS, the reconstructed object can be shared among the multiple places. Furthermore, the space-shared communication space can be synthesized completely with 3D information space through this research.

A stereo display system which enhances reality of the image near the viewers is proposed. In the proposed system, Fresnel lenses are set so that the real image presentation is combined with parallax presentation to enhance reality of 3D space near the viewers. This makes it p05sible for the viewers to feel that their body is included in the image space even when they put their body near the stereo image, which enables more reality-enhanced 3D human interface for teleoperation and VR systems.

In order to achieve space-shared communication, it is essential to develop a truly 3D information space. Therefore, we aimed to construct a unified 3D CG space, that is, a unified 3D geometric modeling system. As for the basic coding method,"Extended Geometry Scheme" is proposed. By using this scheme, we have realized the 3D CG space with unified structure. Another important aspect of the space-shared communication is the development of teleoperation using robots on networks. ft is important that 3D images are displayed naturally without wrong feeling in such real operation space. We have developed a 3D image display method using the parallax and focus function of human's eyes simultaneously. The proposed 3D display method is a combination of real image generation by Fresnel lens and parallax display with stereoscopic glasses. By using this method, it is possible to display realistic 3D images.
