Title (EN) A METHOD FOR CONTROLLING OVERSHOOT IN A VIDEO ENHANCEMENT SYSTEM
(FR) PROCEDE DE REGULATION DU DEPASSEMENT DANS UN SYSTEME D'AMELIORATION VIDEO
Abstract: front page image
(EN)A method for enhancing an edge transition in a video signal comprising the steps of receiving a video signal including an edge transition, generating a correction signal for the edge transition, applying the correction signal to the video signal to produce a corrected signal and restricting the amplitude of the corrected signal to extend between extended maximum and minimum amplitude limits in dependence on the measured maximum and minimum amplitudes of a predefined pattern of pixels adjacent to the edge transition.
(FR)L'invention concerne un procédé permettant d'améliorer une transition de bord dans un signal vidéo, qui consiste à recevoir un signal vidéo comportant une transition de bord, à produire un signal de correction pour la transition de bord, à appliquer ledit signal de correction au signal vidéo de façon à produire un signal corrigé et à restreindre l'amplitude du signal corrigé entre les limites étendues d'amplitude maximale et minimale en fonction des amplitudes maximales et minimales mesurées d'un motif prédéfini de pixels jouxtant la transition de bord.
