“…Currently, Ultra-High Definition Television system (33 megapixels) 18) is used in a prototype 3D video system that includes a camera and display. With an array of 100,000 microlenses (equivalent to a resolution of 100,000 pixels for a reproduced 3D image), image quality equivalent to only a fraction of SDTV quality has been achieved 19) , but the quality is steadily improving. Nevertheless, it will take some time to achieve the level of resolution, range of depth reproduction, and viewing area needed for broadcasting.…”

This paper reviews the current situation of 3DTV systems and clarifies issues to be solved in human factors.Several research activities on 3DTV systems are introduced as candidates that may solve such issues. In the second chapter, various 3DTV systems are classified in terms of cues for human three-dimensional perception. The third chapter describes the human factors on the stereoscopic 3DTV system such as visual discomfort and visual fatigue. Chapter 4 describes advanced 3DTV technologies that reproduce multi-viewpoint 3D images and a 3D spatial image.

“…Because an IP system reconstructs an image with a lot of viewpoints, elemental images with many pixels are required in order to improve the quality of the 3D image. So far, it has been possible to display a 3D image of approximately 100,000 pixels by using a projector with about 8000 scan lines [2]. However, as a single-display device, since a display device featuring more than 8K Super Hi-Vision (SHV) [3] does not exist now, improving the quality of an integral 3D image by using a single display device only is considered to be difficult.…”

The quality of the integral 3D images created by a 3D imaging system was improved by combining multiple LCDs to utilize a greater number of pixels than that possible with one LCD. A prototype of the display device was constructed by using four HD LCDs. An integral photography (IP) image displayed by the prototype is four times larger than that reconstructed by a single display. The pixel pitch of the HD display used is 55.5 μm, and the number of elemental lenses is 212 horizontally and 119 vertically. The 3D image pixel count is 25,228, and the viewing angle is 28°. Since this method is extensible, it is possible to display an integral 3D image of higher quality by increasing the number of LCDs. Using this integral 3D display structure makes it possible to make the whole device thinner than a projector-based display system. It is therefore expected to be applied to the home television in the future.

Capturing method for integral three-dimensional imaging using multiviewpoint robotic cameras

Integral three-dimensional (3-D) technology for next-generation 3-D television must be able to capture dynamic moving subjects with pan, tilt, and zoom camerawork as good as in current TV program production. We propose a capturing method for integral 3-D imaging using multiviewpoint robotic cameras. The cameras are controlled through a cooperative synchronous system composed of a master camera controlled by a camera operator and other reference cameras that are utilized for 3-D reconstruction. When the operator captures a subject using the master camera, the region reproduced by the integral 3-D display is regulated in real space according to the subject's position and view angle of the master camera. Using the cooperative control function, the reference cameras can capture images at the narrowest view angle that does not lose any part of the object region, thereby maximizing the resolution of the image. 3-D models are reconstructed by estimating the depth from complementary multiviewpoint images captured by robotic cameras arranged in a two-dimensional array. The model is converted into elemental images to generate the integral 3-D images. In experiments, we reconstructed integral 3-D images of karate players and confirmed that the proposed method satisfied the above requirements.
