摘要:
A method for coding an HDR picture is disclosed that includes mapping the HDR picture to obtain a SDR picture, determining color correcting parameters, color correcting said SDR picture responsive to said color correcting parameters, and encoding the color corrected SDR picture in a stream. In the method, determining color correcting parameters includes determining an intermediate SDR picture so that at least one color appearance value is preserved between said HDR picture and said intermediate SDR picture, and determining the color correcting parameters from said intermediate SDR picture and from said SDR picture.
