Abstract:
A method of processing a digital image which includes at least one contour zone, including a contour zone sharpness processing. The sharpness processing includes a conversion of the cues regarding level of pixels of the contour zone into initial main cues, lying between zero and a main value dependent on the amplitude of the contour, a sharpness sub-processing performed on these initial main cues so as to obtain final main cues, and a conversion of the final main cues into final cues regarding levels.
