The Ray Space / Light Field is a technique to represent 3D visual scenes by using ‘light rays.’ The concept was proposed in the mid-1990s and it has been investigated as a common data format for Integrated 3D Visual Communications, or an efficient tool for photo-realistic rendering. In the mid-2000s, the Light Field Camera, which is capable of capturing 4D light field by one shot, was launched into market and it attracted much attention as a refocus-after-shot camera. Light field is a collection of multi-view images that are captured in very dense camera intervals, and hence, it can generate free-viewpoint images and refocus the captured images. One of the drawbacks of the light field is its high amount of data and it is a bottleneck at each stage of capture, processing, and display. In the presentation, I start with the definition of the ray space and explain typical methods of capture, processing, and display, and then point out the problem of high data amount. Some of recent researches are surveyed including: computational photography in conjunction with coded aperture or coded mask, compressed sensing, Tensor Display that can reproduce 4D light field from a few 2D image information. |
