Method and device of converting a high-dynamic-range version of a picture to a standard-dynamic-range version of said picture

摘要

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.
