Overview of Three-Dimensional Image Technology

摘要

Many digital broadcast receivers on the market today have three-dimensional (3D) functions to provide an environment for viewers to enjoy stereoscopic images in comfort at home. There is also a boom in 3D content, including movies. The 3D displays of today use a binocular stereoscopic method that requires the viewer to wear special glasses and can cause fatigue. We hope that the future holds another form of 3D TV that will enable us to view 3D images without special glasses and can accommodate a variety of viewing positions. At NHK, we are conducting research on three-dimensional imaging methods such as the integral method, holography, and multi-view images. In this paper, we give a broad overview of three-dimensional image technology and talk about the current state and prospects of research.
