Recent computer vision technology makes innovative progress in 3D visual media industry. In this paper, I would like to introduce our approaches for making use of the computer vision technology in order to achieve innovative application systems of 3DTV and augmented reality. First, I would demonstrate the effectiveness of multiple viewpoint videos and depth videos in 3DTV applications, in which 3D shape reconstructions and view synthesis as computer vision technologies are used. Augmented reality is a method for presenting digital information over the real world with a see-through display. For such application of AR, real-time camera tracking is one of significant technology which is also based on a state-of-art in computer vision.
