摘要： The module (700) comprises:—a low pass filter for low pass filtering luminance component of the image,—a first look up table (710) storing precomputed values of a first expansion function of only low pass filtered luminance values,—a second look up table (720) storing precomputed values of a second expansion function of only luminance values,—a processor (740, 760) configured to multiply an output of the second look up table corresponding to an input luminance value of a color to expand by an output of said first look up table corresponding to an input low pass filtered luminance value associated with said input luminance value.
