摘要： A method for restoring a light signal from digital data defining a colorimetric coordinate of the light signal in a specific colorimetric system, comprises the step of generating a first light signal using a first light restoration unit, the step of generating a second light signal using a second light restoration unit, and the step of generating a third light signal obtained by superimposing the first and second light signals. The second light restoration unit covers a brightness dynamics less than the brightness dynamics covered by the first restoration light unit. The second light restoration unit has a brightness resolution finer than the first light restoration unit.
