Abstract
A digital image including a plurality of pixels is processed. Each pixel has at least one colorimetric component. The processing of the image includes processing for each pixel of a group of pixels of the image and for each colorimetric component of the pixel. In this processing, a modification is made to the value of the colorimetric component so as to obtain a modified value situated inside or outside a colorimetric range. A comparison is made of the modified value to the upper and lower limits of the associated colorimetric range. If the corrected value is outside the associated colorimetric range, a corrected value equal to an additional value is assigned to the corresponding colorimetric component of the pixel. The additional value is chosen to be unique and included in the associated colorimetric range and different from the values of the limits of the associated colorimetric range.
