Abstract
In this paper, a new method for efficient generation of video hologram for 3-D video is proposed by combined use of redundant data of 3-D video and look-up table techniques. That is, temporal redundant data in inter-frame of 3-D video image is removed using differential pulse code modulation (DPCM) method between frames then inter-line redundant data in intra-frame of 3-D video image is also removed using DPCM algorithm between lines. Experimental results show that, in the proposed method, the average number of calculated object points for 3-D objects have been reduced by 23.3% for top-down scanning scheme, compared to the conventional TR_NLUT method. And, the average calculation time for one object point has been also reduced by 21.0%, compared to the conventional TR_NLUT. Good experimental results with 3-D test moving pictures finally confirmed the feasibility of the proposed method in fast generation of CGH patterns for 3-D videos.
