Abstract
An optical 3D screen usually shows a certain diffuse reflectivity or diffuse transmission, and the multi-projection 3D display suffers from decreased display local contrast due to the crosstalk of multi-projection contents. A tone mapping based optimizing method is innovatively proposed to suppress the crosstalk and improve the display contrast by minimizing the visible contrast distortions between the display light field and a targeted one with enhanced contrast. The contrast distortions are weighted according to the visibility predicted by the model of human visual system, and the distortions are minimized for the given multi-projection 3D display model that enforces constrains on the solution. Our proposed method can adjust parallax images or parallax video contents for the optimum 3D display image quality taking into account the display characteristics and ambient illumination. The validity of the method is evaluated and proved in experiments.
