초록
A sub-pixel multiplexing algorithm for generating multi-view images on an autostereoscopic three-dimensional (3D) display at high speed is proposed. Generally, sub-pixel multiplexing in an autostereoscopic 3DTV system is to assign R, G, B colour sub-pixels of multiple view images at the proper position on the display such that a proper view image can be seen in accordance with the viewer's position. The upscaled sub-pixel multiplexing algorithm proposed is composed of bilinear upscaling and a weighted view overlay. Even though upscaling multiple view images requires too much resources and increases system complexity, the proposed algorithm can significantly reduce complexity from an implementation point of view while providing high-quality 3D views. Specifically, the advantage of the proposed weighted view-overlay technique is that several overlaid view images decide the colour value of the sub-pixel, which results in increasing the subjective quality of view images. Through an experiment, it is confirmed that the image quality of generated multi-views with the proposed algorithms is notably better than the existing simple techniques.
