An enhanced algorithm of image mapping method is proposed for the computer-generated (CG) integral imaging system. Integral imaging is one of the attractive autostereoscopic three-dimensional (3D) display methods since it provides both vertical and horizontal parallaxes with full colors and it needs no special viewing aids on the observer. The CG integral imaging system uses the set of elemental images generated by computer graphics instead of the pickup process using the lens array. The process to obtain the set of elemental images using computer graphics is called image mapping. In this paper, we propose an enhanced image-mapping algorithm, named viewpoint vector rendering, to improve the speed of the elemental-image generation and to be more robust so that it is less affected by the system factors and the object image quality, as compared to the previous methods. Since the proposed algorithm can support the real-time generation of elemental images, it is possible to realize the CG integral imaging system applied for an interactive multimedia system. The feasibility and the efficiency of the proposed technique is verified and analyzed by mean of some experimental results.
