Abstract
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.
