Abstract:
Automultiscopic displays enable glasses-free 3D viewing by providing both binocular and motion parallax. Within the display field of view, different images are observed depending on the viewing direction. When moving outside the field of view, the observed images may repeat. Light fields produced by lenticular and parallax-barrier automultiscopic displays may have repetitive structure with significant discontinuities between the fields of view. This repetitive structure induces visual artifacts in the form of view discontinuities, depth reversals, and extensive disparities. To overcome this problem, a method modifies the presented light field image content and makes it more repetitive. In the method, a light field is refined using global and local shearing and then the repeating fragments are stitched. The method reduces the discontinuities in the displayed light field and leads to visual quality improvements. Benefits of the method are shown using an automultiscopic display with a parallax barrier and lenticular prints.
