A Fast Image Multiplexing Method Robust to Viewer's Position and Lens Misalignment in Lenticular 3D Displays

摘要

Among various autostereoscopic display systems, the lenticular display is one of the most popular systems due to its easy manufacturability. For N-view lenticular display, N view images are to be regularly sub-sampled and interleaved to produce a 3D image. A lenticular system provides the best quality only when a viewer locates at a pre-determined optimal viewing distance and the lenticular sheet is precisely aligned on the LCD pixel array. In our previous work, we have proposed an algorithm to compensate the viewer's position change and the lenticular misalignment. However, since the previous algorithm requires a considerable computational burden, we propose a new fast multiplexing algorithm. To improve the processing speed, we introduce a mapping table instead of directly using complex equations. In contrary to the previous algorithm, the proposed one can make real time compensation possible without degrading image quality.
