Abstract:
1. A method for processing image data on a target display device, the method comprising: obtaining multiple sections of image data associated with an input data stream produced using a reference display device having one or more reference display device parameters, wherein each section of the multiple sections of the image data is associated with respective metadata arranged in one or more variable levels selected from multiple predetermined levels, wherein a higher level of metadata provides additional information to a lower level of metadata for calculating color management parameters for processing a corresponding section of the image data, and wherein a particular level of the multiple predetermined levels includes metadata representing the one or more reference display device parameters; determining that metadata associated with a particular section of the multiple sections of the image data is arranged to include the particular level of metadata representing the one or more reference display device parameters of the reference display device; and in response to determining that the metadata associated with the particular section of the image data is arranged to include the particular level of metadata representing the one or more reference display device parameters of the reference display device, calculating color management algorithm parameters for processing the particular section of the image data on the target display device based on the one or more reference display device parameters of the reference display device and one or more other parameters represented by a level of metadata different than the particular level of metadata that is associated with the particular section of the image data.
