Three-dimensional effect can be obtained when 2D picture will be seen through Micro Lens Array(MLA) on which micro lens are put side by side without any gap. When the MLA is bent, a 3D effect will be more stressed. This stress is born on the display image by the distortion toward the depth direction of the total image. The leaned micro lens is regarded as a micro lens being straightly faced to the display image with shortened focus distance. Due to this, the display image can be seen without any distortion on up and down sides and also right and left sides. The human brain recognizes the distortion toward the depth direction of the image unconsciously and also recognizes more stressed three-dimensional image due to a kind of illusion.

We have been researching a 3-D displaying method satisfying "Super Multi-View condition"that is the method of producing natural 3-D images by displaying multi-perspective images with fine perspective-pitch, which is narrow than the pupil diameter of viewer's eyes. To realize this method, we propose new display system which uses projection optics and a concave mirror.

There are materials handling, loading and unloading, and so on in the jobs of the physical distribution field. And, the VR system which has broad view is necessary so that we may do the imaginary experience of these jobs. Therefore, we built the VR system of the small size which had broad view. We explain about the outline of the facilities design system which used sphere screen and the application of VR to the physical distribution.

We propose a highly scalable and flexoble display system which can realize arbitrary resolution and structure of screens with PC cluster system. In this system, an original hardware which can synchronize stereo images generated with each PC is installed, and large continuous stereoscopic display is realized. This hardware is also able to transfer generated images from one PC's framebuffer to the other PC's framebuffer. Using this function, we propose a method for load balancing in PC cluster system and prior rendering of regions which users view. We show the advantage of these methods by simple simulation.

The authors are interested in a construction of collaborative space, which is made from some real worlds or combination between real world and virtual world connected by high-speed network, such as JGN(Japan Gigabit Network). This paper describes a WHD(Wide/Double HD)transmission system, that can capture, transmit, and display moving pictures of twice as many resolution as HDTV.

We have studied a basic technical approach to the realization of the 3D TV system applying holography technique using liquid crystal display(LCD)panels. The visual-angle and visual-field are so small that a long distance should be required for the good observation of reconstructed image. It becomes so difficult to get the clear image since the hologram image is very small. In addition, it is important to consider the chromatic aberration and expansion of the visual angle, in the case of the white light processing. We report here that by our lenses system, the visual field can be more widely expanded and it seems to be more useful for realizing color holography television system.

Parallax barrier technology and lenticular lens technology are two principal technologies to display no-glasses 3-D images. But the parallax barrier has a defect of cutting off the light and the 3-D screen becomes dark. So until recently was not adopted to realize the no-glasses 3-D display. But we adopted this technology because of its simple construction and preciseness. And we have improved this technology in order to be applicable to the LCD. This paper explains the development and applications of our no-glasses 3-D displays adopting parallax barrier technology named "Image-Splitter".

A three-dimensional(3-D) television system based on Integral Photography is experimentally developed. In this system, elemental images of an object are formed by a GRIN lens array, and are directly captured by a television camera. A large aperture convex lens is introduced in front of the GRIN lens array to control the depth range of the reproduced image. The video signal of a group of elemental images is transmitted to a display device that combines a liquid crystal panel and an array of convex micro-lenses, producing a color autostereoscopic 3-D image in real-time.

Recently a study of Virtual-Reality becomes active. Expectation to 3-D reproduction technology rises with it. Electro-holography using Spatial light modulator(SLM)attracts attention, because natural 3-D animated image is provided. In this paper recent development of 3D-TV by Electro-holography is reported. We consider the conditions to holographic TV such as input, transmission and display systems. Also we consider about fast hologram calculation because It is important to execute hologram calculation at high speed to realize the real time electro-holography. Then we consider the possibility of real time holography.
