In this paper, statistics such as distribution of peak luminance, region of peak luminance in frames, colors of high dynamic range contents are analyzed Based on the analysis, essential requirements for future high dynamic range displays are discussed. For our statistical study, various types of high dynamic range content that have been provided by studios or content providers are considered. Since they have been being supplied by limited studios and network-based content providers, a large amount of the content is movies that utilize limited dynamic range, average luminance and color gamut compared with the other dynamic contents. In spite of the trend, we claim that capability of high dynamic range displays do not need to be restricted by considering the current content industry since very bright high dynamic range contents that have higher luminance and wide color information absolutely need to be also considered when defining specification of future high dynamic range displays. To support this fact, we review the analysis results and requirements which are needed to sufficiently represent vivid high dynamic range presentation to match the human visual perception capability.

  • For more than 30 years, the Electronic Imaging Symposium has been serving those in the broad community - from academia and industry - who work on imaging science and digital technologies. The breadth of the Symposium covers the entire imaging science ecosystem, from capture (sensors, camera) through image processing (image quality, color and appearance) to how we and our surrogate machines see and interpret images. Applications covered include augmented reality, autonomous vehicles, machine vision, data analysis, digital and mobile photography, security, virtual reality, and human vision. IS&T began sole sponsorship of the meeting in 2016. All papers presented at EIs 20+ conferences are open access.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in perpetuity. Copyright restrictions on papers vary; see individual paper for details.
