Perceptual Display: Towards Reducing Gaps Between Real World and Displayed Scenes

While tremendous improvement in displayed image quality can be observed in recent years, existing displays fall short in reproducing brightness, contrast, and depth ranges in the real world. Moreover, a discrete nature of displays in spatial and temporal domain has important implications when reproducing continuous in nature real world signals, in particular in the context of object motion and interactions with eye gaze directions.

In this talk we discuss important properties of human visual perception, which can be employed to apparent improvement of displayed image quality without the need of enhancing physical display parameters. First, we demonstrate how to display image details beyond physical resolution of display devices and we investigate the impact of image framerate on the perception of hold-type blur and judder. Then we focus on perceived depth and viewing comfort improvement on stereoscopic and multiscopic displays by exploiting complex interactions between monoscopic depth cues, such as motion parallax, and binocular vision. In particular, we discuss depth retargeting while reducing perceived depth loss and gaze-driven depth manipulation. We also consider stereoscopic cinematographic applications, where proper handling of scene cuts, reflective/refractive objects, and film grain require special attention. Finally, we discuss the role of eye lens accommodation and we present a prototype stereoscopic display that can reproduce this important viewing cue.

Karol Myszkowski is a senior researcher at the MPI Informatik, Saarbruecken, Germany. In the period from 1993 till 2000 he served as an associate professor in the Department of Computer Software at the University of Aizu, Japan. In the period from 1986 till 1992 he worked for Integra, Inc. a Japan-based, company specialized in developing rendering and global illumination software. He received his PhD (1991) and habilitation (2001) degrees in computer science from Warsaw University of Technology (Poland). In 2011 he was awarded with a lifetime professor title by the President of Poland. His research interests include global illumination and rendering, perception issues in graphics, high dynamic range imaging, and stereo 3D. He co-authored the book High Dynamic Range Imaging, and participated in various committees and editorial boards. He also co-chaired Rendering Symposium in 2001, ACM Symposium on Applied Perception in Graphics and Visualization in 2008, Spring Conference on Computer Graphics 2008, and Graphicon 2012.
