78.1 - Invited Paper: Gamut Rings Color Scope for Use with Wide-Gamut Display Systems (3:10 PM - 3:30 PM)
  • Kenichiro Masaoka
    NHK Science & Technology Research Laboratories/NHK Foundation Tokyo Japan


  • A new tool based on gamut rings can monitor the lightness, chroma, and hue distributions of the pixel colors of input images in a single 2D diagram. The perceptually intuitive visualization facilitates more efficient and effective color grading, thereby broadening the market's understanding of the benefits of wide-gamut displays.

78.2 - Invited Paper: Distinguished Paper: Assessing Color Capability with Gamut Ring Intersection (3:30 PM - 3:50 PM)
  • Euan Smith
    42 Technology St Ives United Kingdom


  • The gamut ring intersection diagram extends the gamut ring diagram by representing how the color gamut of a test device covers a reference color gamut. The means of calculating and rendering a gamut ring intersection diagram will be provided, and advantages demonstrated through analysis of measured and synthetic display gamuts.

78.3 - A Tristimulus Electro-Optical Model Describing Interactions of an RGB Backlight Unit and an LC Panel (3:50 PM - 4:10 PM)
  • Ramazan Ayasli, Maria Cirillo, Chihao Xu
    Saarland University Saarbruecken Germany


  • This paper presents a color model to describe the interaction of a variable color, locally dimmed RGB backlight with an LC panel. The model extends 1D luminance to 3D tristimulus. Input variables include RGB-LED duty ratios in addition to the RGB subpixel gray values. LC pixel XYZ coordinate values can be calculated and a method for parameter extraction is shown.

78.4 - Invited Paper: Defining and Characterizing Programmatic Image Sequences for Multi-Disciplinary Applications (4:10 PM - 4:50 PM)
  • Florian Friedrich
    FF Pictures GmbH Oberschleissheim Germany

  • Timo Kunkel
    Dolby Labs, Inc. San Francisco CA US


  • This paper introduces a framework for defining and characterizing content, specifically tailored for reproducible testing in video processing, energy consumption, and encoding tests. The approach presented integrates advanced HDR display technologies and provides a comprehensive analysis with practical examples. This paper marks the public release of a set of these sequences.
