The present invention concerns a device for enhancing a digital image comprising: - a circuit (20) for detecting regions of the image containing predetermined types of objects and a background; and - a circuit (30) for processing said regions by modifying image parameters defining the contrast of the image, wherein said circuit (30) of a region comprises the determination, in a module (33), of two separate target range segments for said image parameters, a lower segment and a higher segment, image parameters of the background being mapped, in a module (34), to one of said segments and image parameters of the objects being mapped, in said module (34), to the other of said segments to maintain at least a predetermined relative contrast between said object and said background. |
