Digital reproductions often aim to recreate the visual experience of viewing a physical scene. Current reproduction pipelines are limited by luminance dynamic range typical cameras and displays, which is much narrower than many scenes. Thus, reproducing contrast detail in way that replicates scene challenge, requires mapping high content lower via tone algorithms. However, because lossy process, it can compromise visibility perceptual realism. It has recently been suggested binocular vision be leveraged improve perceived showing differently mapped images two eyes (dichoptic mapping). Several such methods have proposed but results for improving quality mixed. We hypothesized these mixed were related different baseline algorithms used comparisons. To address this issue, we conducted studies using image ratings two-alternative forced choice task ask whether dichoptically systematically preferred over alternative presented identical both eyes. also examined three-dimensionality potential applications stereoscopic 3D content. Our data suggest preferences may driven preference one out dichoptic pair, rather pair together. Consistent with prior work, found as appearing more three-dimensional. In conclusion, when goal digital convey realistic contrast, not consistently conventional mapping, enhance impression.
