Suppression of band-shaped noize for integral volumetric imaging display

Abstract

This paper proposes a method to suppress view dependent deterioration of image quality for integral volumetric imaging displays. Most of the volumetric displays present depth information by the layered image planes. An observer can see a correct image right in front of the display, while the pixels are shifted from one another when an observer sees it from the corner of the display. The shift of pixels causes emergence of band-shaped noise composed of bright part and dark part. The authors realize suppression of the noise by a non-negative edge filter, which enables reproduction of the original image only with addition.
