摘要：
This method is based on a linear combination of a first encoding of each color based on a first virtual display device notably defined by a first white and a first set of primaries corresponding to colors reflected from the scene under the illumination with the highest luminance, and of a second encoding based on a second virtual display device notably defined by a second white and a second set of primaries corresponding to colors reflected from the scene under the illumination with the lowest luminance, wherein the weight assigned to the first encoding is proportional to the luminance of said color.
