  • Method and device of converting a high dynamic range version of a picture to a standard-dynamic-range version of said picture
    Patent number: 10764549
    Abstract: The present disclosure generally relates to a method and device of converting a HDR version of a picture to a SDR version of this picture. The method is characterized in that it converts the HDR version to the SDR version of the picture according to: a first indicator that indicates the presence of color mapping parameters; a second indicator that indicates whether a device is configured to convert the HDR version to the SDR version of the picture by taking into account said color mapping parameters; and a third indicator that indicates whether converting without taking into account said color mapping parameters is inhibited.
    Type: Grant
    Filed: September 13, 2018
    Date of Patent: September 1, 2020
    Assignee: INTERDIGITAL VC HOLDINGS, INC.

  • Method and device of converting a high-dynamic-range version of a picture to a standard-dynamic-range version of said picture
    Patent number: 10104354
    Abstract: The present disclosure generally relates to a method and device of converting a high-dynamic-range (HDR) version of a picture to a standard-dynamic-range (SDR) version of this picture. The method is characterized in that it converts the high-dynamic-range version to the standard-dynamic-range version of the picture according to: a first indicator (I1) that indicates the presence of color mapping parameters; a second indicator (I2) that indicates whether a device is configured to convert the high-dynamic-range version to the standard-dynamic-range version of the picture by taking into account said color mapping parameters; and a third indicator (I3) that indicates whether converting without taking into account said color mapping parameters is inhibited.
