High-dynamic range imaging, better known by its acronym, HDR, has established itself as a foundational component for aspects defining today’s image fidelity. HDR technology is widely supported by millions of devices covering the whole production pipeline from cameras to post-production tools, deployment systems, and displays and is embraced by content creators, providers, and consumers alike. HDR imaging is based on several key concepts that facilitate perceptually meaningful, artistically compelling, and technologically effective delivery of movies, TV shows, and video games that are more immersive and realistic than previously possible. These improvements offered by HDR imaging have required significant changes to the underlying technologies, such as increases in signal range and granularity, as well as the implementation of advanced content remapping approaches. They also brought to the forefront some visual phenomena and perceptual effects that in the past were not considered relevant to everyday viewing, making HDR content presentation qualitatively different from standard dynamic range (SDR) content consumption. This seminar provides an overview of these key concepts enabling today's HDR ecosystem, including technological aspects, industry standards, formats, and applications and places them into context of the unique perceptual properties HDR imaging adds to the creative presentation of content.
Timo Kunkel is director of Image Technology & Standards in the CTO office of Dolby Labs, Inc. Over the past 15 years, he has been investigating the technical and perceptual aspects of HDR and wide color gamut imaging with a focus on advanced display approaches, and has been involved in developing the core concepts of what is now Dolby Vision. Kunkel has published and taught about HDR concepts and technologies throughout our industry for many years. He is also a member and technical expert with the CIE, ICC, SID ICDM, and IEC TC100 and 110. He holds a Ph.D. in computer Sscience from the University of Bristol, UK, and an M.Sc. from the University of Freiburg, Germany.
Robert Wanat is a staff researcher at LGE Zenith. His work revolves around creating models of the human visual system that simulate visual perception and how it's affected by changing viewing conditions. Wanat graduated with a Ph.D. from Bangor University in Bangor, Wales, and an M.Sc. from West Pomeranian University of Technology in Szczecin, Poland.
