    摘要: 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.

    摘要: The invention concerns a device for processing a digital image comprising at least one contour region, including sharpness processing of the contour region. The sharpness processing includes converting data of the level of pixels of the contour zone into initial main data (step 2), ranging between a minimum value, for example 0 and a main value based on the amplitude of the contour, a sharpness sub-processing performed on said initial main data so as to obtain final main data (steps 3 to 10), and converting the final main data into final data of levels (step 11).
