Multiview display system and method with adaptive background
An adaptive background multiview image display system and method provides improved multiview image quality. Systems and methods may involve generating crosstalk data that reduces crosstalk between a first view of subject image and a second view of the subject image. The subject image may be a multiview image to be overlaid on a background image. A crosstalk violation may be detected in the subject image based on the crosstalk data. At least one of a color value or a brightness value of the background image is determined according to a degree of the crosstalk violation to generate the background image. The subject image may then be overlaid on the generated background image.

6. The method of adapting a background of a multiview image of claim 1 , wherein the crosstalk violation is removed from the subject image by setting pixel values corresponding to the crosstalk violation to zero.
7. The method of adapting a background of a multiview image of claim 1 , further comprising identifying the location of the crosstalk violation by detecting an edge formed by a set of pixels that correspond to pixel values associated with the crosstalk violation.

12. The multiview image display system employing an adaptive background of claim 8 , wherein the visual parameter comprises at least one of a color pixel value or a brightness pixel value.
13. The multiview image display system employing an adaptive background of claim 8 , wherein the plurality of instructions, which, when executed, further cause the processor to determine the visual parameter to generate at least one of a halo effect or color gradient based on identifying a location of the portion of the subject image and mapping the location to the location on the background image.
14. The multiview image display system employing an adaptive background of claim 8 , wherein the crosstalk violation is removed from the subject image by setting a pixel value corresponding to the crosstalk violation to zero, the visual parameter being modified to compensate for removing the crosstalk violation.
