A Unified Method for Crosstalk Reduction in Multiview Displays

The slanted lenticular sheet-based multiview display usually suffers both extrinsic crosstalk resulting from fabrication errors or assembling errors and intrinsic crosstalk originating from the leaked light from the two closest neighboring views. In this paper, a unified method is proposed to eliminate the extrinsic crosstalk and alleviate the intrinsic crosstalk simultaneously by adjusting the predefined view index (i.e., the corresponding viewpoint number) and grayscale intensity of each LCD subpixel. Two sets of patterns are utilized: structured light patterns are applied for building the correspondence between LCD subpixels and the captured photos pixels, and intensity test images are used for determining the brightness of LCD subpixels observed at given viewing points. Then the optimal view index for each LCD subpixel can be obtained for extrinsic crosstalk elimination according to the calculated correspondence and the estimated subpixel brightness. Moreover, the crosstalk coefficients for each subpixel can also be computed according to the correspondence and brightness, which are used for intrinsic crosstalk reduction. Experimental results prove the effectiveness of our method.
