A method for processing at least one digital image for reproduction on a display device. The image includes image elements, an image element being associated with color information having, in a first color space, a luminance component and chrominance components. The method includes the following acts: determining a number of image elements, known as “bright” elements, at least the luminance component of which has a value greater than a first predetermined threshold; evaluating a maximum tolerated brightness value as a decreasing function of the number of counted image elements; and transforming the first luminance components of the image elements to second luminance components, including for an image element, calculating an intermediate luminance value by applying an expansion exponent to the first luminance component value and multiplying the intermediate value calculated by the evaluated maximum tolerated luminosity value.
