Abstract

Free-viewpoint TV (FTV) is an ultimate 3DTV that enables users to view a 3D world by freely changing their viewpoints as if they were there. FTV will bring an epochal change in the history of television since this function has not yet been achieved by conventional TV technology. FTV will greatly contribute to the development of industry, society, life and culture because FTV has an infinite number of viewpoints and hence it has very high sensing and representation capabilities. Tanimoto Lab of Nagoya University proposed the concept of FTV and constructed the world’s first real-time system including the complete chain of operation from image capture to display. We also realized FTV on a single PC and FTV with free listening-point audio. FTV is a ray-based system rather than a pixel-based system. We are creating ray-based image engineering through the development of FTV. MPEG regards FTV as the most challenging 3D media and has been conducting the international standardization activities of FTV. The first phase of FTV was MVC (Multi-view Video Coding) and the second phase of FTV is 3DV (3D Video). MVC was completed in March 2009. 3DV is a standard that targets serving a variety of 3D displays.
