Depth-Compressed Expression for Integral 3D Displays

Abstract

Integral 3D imaging has technical challenges in displaying deep depth information with high quality since the depth reconstruction range is restrictive. To display a variety of scenes with high quality, we introduced 'depth-compression expression,' in which the depth of scenes are compressed, or modified in the axial direction, so that the appearances of the depth-compressed scenes are kept natural for viewers. By taking advantages of the characteristics of human vision, we found that viewers did not feel unnaturalness even for the depth-compressed scenes with half the depth of the originals..
