  • Pipeline for high dynamic range video coding based on luminance independent chromaticity preprocessing
    Patent number: 10735628
    Abstract: The disclosure describes a high dynamic range video coding pipeline that may reduce color artifacts and improve compression efficiency. The disclosed pipeline separates the luminance component from the chrominance components of an input signal (e.g., an RGB source video) and applies a scaling of the chrominance components before encoding, thereby reducing perceivable color artifacts while maintaining luminance quality.
    Type: Grant
    Filed: August 27, 2019
    Date of Patent: August 4, 2020
    Assignee: Disney Enterprises, Inc.
    Inventors: Samir Mahmalat, Tunc Aydin, Aljosa Smolic

  • Luminance comfort prediction and adjustment
    Patent number: 10380973
    Abstract: One or more levels of maladaptation are calculated relative to frames of media content having abrupt jumps from periods of low illumination to bright illumination when visual acuity may be lost and/or discomfort may be experienced. These levels of maladaptation may be correlated with subjectively determined levels of perceived luminance discomfort. Based upon the levels of perceived luminance discomfort that can be derived from the levels of maladaptation, the media content may be adjusted.
