"3D Consortium study session organized by the Technical Sub-committee"
(Venue: Room 502, Nippon Seinenkan in Sendagaya, Tokyo)
June 17, 2011
"Mr. Tadashi Ishikawa delivering an opening address (Leader of the Technical Sub-committee /Toshiba Corporation)"

On June 17, a Study Session was organized by the Technical Sub-committee at Nippon Seinenkan.
The theme of the study session was "The latest trends of naked eye 3D image technologies".
In 2010 which was referred to as the first year of 3D, many products supporting 3D were released from various manufacturers. The most significant differences of this wave of 3D from the past similar waves were that digital image processing technologies enabled 3D images with higher resolution, therefore production of high quality 3D works was possible with these technologies and the high expectation of the general public toward 3D was recognized anew by the continuous successes of 3D movies.
Concerning the display method, expansion in the range of naked eye 3D technologies was noticed such as mobile 3D and 3D TV in addition to the existing method using glasses. Considering such a situation, the Technical Sub-committee invited 6 experts to lecture on the latest trends about the naked eye 3D image technologies focused on naked eye 3D display method, and a transmission scheme based on multi-parallax and multi-parallax computer graphic representation method. Exhibitions with demonstrations were simultaneously held.
There were 36 members at the study session for a total of 67 people attending. Most people were attended until closing, and exchange of opinions was carried out.

"3D images and human property"

Principal of the Tokyo Optometric College
Mr. Toyohiko Hatada

> Lecture Outline
People who are used to 2D images feel discomfort when they look at 3D images which are differently reflected on each eye in a subtle way. Causes of fatigue were sorted out anew to check the conditions to achieve natural and comfortable 3D images from the biological standpoints.
"Introduction of 3D technologies - Shoot, touch and play"

Executive Research Engineer, Director, Frontier Technology Research Group, Research Laboratories, NTT DOCOMO, INC.
Mr. Tsutomu Horikoshi

> Lecture Outline
The 3D technologies which were exhibited at CEATEC last year have been introduced. This "shoot and play" 3D technology enables displaying pseudo 3D images on existing mobile phones with a 2D display. Images with multiple viewpoints are generated with image processing of 3D images shot by stereo cameras. Images based on different viewpoints are displayed according to the gradient of mobile terminals. It is possible to adjust the amount of disparity according to the display size which leads to offering 3D images which are comfortably viewed on mobile terminals (exhibition with demonstrations). The "shoot and play" 3D technology realized the feeling of touching protruding 3D images. This lecture briefly introduced the principle of this technology.
"Trial production of 3D contents with multiple viewpoints at high resolution"

President, ROKKON Inc.
Mr. Yukihiro Deguchi

> Lecture Outline
How far can the improvement in comfortableness of 3D images shown on handheld displays and their solid impact increase people's interest in 3D with inevitability? With this lecture, merits and future possibilities acquired through the trial production of 3D computer graphics contents with multiple viewpoints by using mobile displays at high resolution were considered (exhibited with demonstrations).
"Naked eye 3D displays and applications which enable editing, viewing and listening to 3D contents"

Superintendent, Office of President, I-O Data Device, Inc.
Mr. Katsuyuki Toyota

> Lecture Outline
Introduction of an external naked eye 3D display which can view and listen to 3D contents on most PCs just by connecting with a USB cable. It supports viewing and listening to most 3D contents, still and motion images in 3D and direct viewing and listening to YouTube3D (exhibition with demonstrations).
"Free viewpoint TV (FTV) and MPEG standardization of 3D technologies"

Graduate School / School of Engineering, Nagoya University
Professor, Masayuki Tanimoto

> Lecture Outline
A free viewpoint TV (FTV) is an ultimate 3D TV which enables users to freely move viewpoints when they see three dimensional scenes. This lecture introduced FTV technologies and MPEG standardization of technologies which enables the showing of 3D images on 3D displays based on a two-lens system and a multi-view system.
"Wide visual field naked eye 3D display with smooth movement parallax"

Multimedia Laboratory, Corporate Research & Development Center, TOSHIBA CORPORATION
Mr. Masahiro Baba

> Lecture Outline
This lecture introduced the integral imaging method and naked eye 3D display techcnologies focusing on glassless 3D REGZA.
