3D TV requires multiple view images and it is very important to adjust parameters used for capturing and display of multiview images, which includes size of view images, focal length, and camera/viewpoint interval. However, the parameters usually vary from systems to systems and that causes a problem regarding interconnectivity between capturing and display devices. The Ray-Space method provides one of the solutions to such problems raised in 3D TV data capturing, transmission, storing, and display. In this paper, we first review the Ray-Space method and describe its relationship with 3D TV. Then, we introduce 3 types of Ray-Space acquisition systems: 100-camera system, space/time-division system, and portable multi-camera system. We also describe test data set provided for MPEG (Moving Picture Experts Group) Multiview Video Coding and 3D Video activities.
