Paper Abstract

The traditional method to generate CGH patterns takes up many times thus it is difficult to implement the actual use. To improve the computation speed, the pre-computed look-up table containing all possible elemental fringes is proposed. But to generate CGH for many frames of video images, LUT method also takes up many times, because elemental fringe patterns for entire points of each frame are summated. In the ordinary video images, when a frame is converted to next frame, the case that the whole picture be changed is rare. That is, video images have much redundancy between adjacent frames. In this paper, an efficient generation method of hologram pattern for video images using general property of video images and principle of LUT method is proposed.
