METHODS AND SYSTEMS FOR DISPLAYS WITH CHROMATIC CORRECTION HAVING DIFFERING CHROMATIC RANGES

摘要

The invention relates to methods and systems for displays with chromatic correction having differing chromatic ranges. A method comprises carrying out (530) an initial chromatic correction on an image content source by means of a display of the reference type having a reference chromatic range to give a reformatted image content having undergone a chromatic correction for display on displays of the reference type with the reference chromatic range. The method further comprises determining (586) a first set of metadata defining a description of mapping a chromatic range for a chromatic range mapping of a display of the non-reference type with a non-reference chromatic range into the display of the reference type. The method further comprises carrying out (535) an ultimate chromatic correction by means of the display of the non-reference type and reformatted image content having undergone a chromatic correction to give a second set of metadata relating to displays of the non-reference type with the non-reference chromatic range. The method further comprises generating (566) a final set of metadata from the first set of metadata and the second set of metadata for an ultimate chromatic transformation which chromatically transforms the reformatted image content having undergone a chromatic correction for display on a display of the non-reference type for client use. The image source content is reformatted for client use only by displays of the reference type having the reference chromatic range.
