A method of processing a digital image, said image comprising a plurality of pixels, the method comprising a computation step (S1) wherein a histogram of the distribution of the number of pixels of the image as a function of their luminance is computed, a step (S2) for lightening the image based on said histogram comprising a subdivision (S20) of the pixels of the image into a first set of pixels having luminance values between a low threshold and a high threshold and into a second set of pixels having luminance values greater than said high threshold, a first luminance processing operation (S21) on the pixels of the first set of pixels and a second luminance processing operation (S22) on the pixels of the second set of pixels, the two luminance processing operations (S21, S22) being different, the first processing operation (S21) comprising an increase in the luminance of the pixels of the image. |
