High Dynamic Range Imaging - Technologies, Applications and Perceptual Considerations
High-Dynamic Range imaging (“HDR”) has established itself as a foundational
component when looking at the 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 webinar is an overview of these 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 focus on advanced display approaches and has been involved in developing the core concepts of what is now Dolby Vision. Timo has published and taught about HDR concepts 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. Timo holds a PhD in Computer Science from the U Bristol, UK, and a MSc from U Freiburg, Germany.
