Cross-interference reduction using spatial mapping for integral imaging

Abstract

Because a three-dimensional image can be seen from a desired viewpoint without the aid of special viewing glasses, integral imaging is an ideal way to create 3D auto-stereoscopic images. But 3D displays suffer from crosstalk, an effect that reduces 3D image quality or even inhibits the viewer's ability to correctly perceive depth.Previous optical crosstalk reduction methods decrease the amount of visible crosstalk. However, these methods are not necessarily easy and may not be practical. We describe a new spatial-mapping method based on gradient of elemental image to overcome the problem. This method can eliminate the crosstalk to a great extent. Experimental results indicating the advantages of this method are shown.
