Abstract

An autostereoscopic imaging system, which displays moving actual images created from 2D video and depth data is proposed. The system consists of a depth camera, signal processing algorithms, and an integral display prototype. The specifications are as follows: (a) Depth camera: a monocular VGA video camera with optical distance sensor captures 2D texture image and its depth map simultaneously. (b) Signal processing: 10*10 parallax images are created from the video stream, and the angle between two neighboring parallax images is 0.8 degrees. (c) Display: The display device is contact type (LCD) or projection type (LCOS), and the optical device is a microlens-array. 2D resolution of the 3D image is 720 cycle/radian at a viewing distance and a viewing zone is about 8 degrees. Noticeable defects due to occlusions are not found within the viewing zone. The method of transmission of texture and depth data has higher compatibility with conventional coding technologies than transmission using compressed parallax images. And the transmission method enables the choice of various types of displays and how the contents are displayed. Therefore we believe that this system is a candidate for the future 3D television system.
