Full Parallax Table Top 3D Display Using Visually Equivalent Light Field

摘要

A new full parallax light field 3D display that optically interpolates the rays emitted is proposed. Using a barrier with special aperture structure, we achieve interpolation by optical linear blending not only for the horizontal direction, but also for the vertical direction. Linear blending produces visually equivalent intermediate view point images equivalent to the real views if the disparity between the two images being blended are small enough. Therefore, a high feel of existence can be produced as the interpolation yields smooth motion parallax. Since interpolation reduces the number of viewpoints, number of pixels in each direction can be increased yielding high resolution. In this demonstration, we reproduce CG objects and scenes of a ball game on a table top.
