METHOD FOR GENERATING 3D VIDEO COMPUTER GENERATED HOLOGRAM USING LOOK-UP TABLE AND SPATIAL REDUNDANCY, AND APPARATUS THEREOF

摘要

A method of computing a computer generated hologram (CGH) using a look-up table and spatial redundancy and an apparatus thereof are disclosed. The method in accordance with an embodiment of the present invention can includes computing one principal fringe pattern for each point of a target object that is separated by a same distance from a reference point of a hologram plane, storing the principal fringe pattern in accordance with a distance between each point of the target object and the reference point, computing identity data representing whether each point of an input image and adjacent points are identical to one another, computing an n-point fringe pattern by combining n principal fringe patterns and computing hologram information by matching the n-point fringe pattern to n successive points identified from the identity data. Here, the n is a natural number.
