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.
