Reducing View Transitions Artifacts In Automultiscopic Displays

摘要

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.

1. A computer-implemented method comprising:
storing multi-view image content in an electronic memory; performing at least one of reducing and removing the visibility of one or more artifacts from the multi-view image content by modifying the multi-view image content based upon at least one of: shearing the multi-view image content globally, shearing the multi-view image content locally, and stitching the multi-view image content; and based upon the modification of the multi-view image content, providing one or more updated multi-view images with improved visibility as compared with the multi-view image, at least with respect to the one or more artifacts.
