Nous avons proposé une méthode pour réduire le flou de mouvement LCD dans le domaine MPEG et analyser la cause du flou de mouvement LCD. Le problème du flou de mouvement de l'écran LCD est dû au temps de réponse lent des cristaux liquides et à la méthode d'affichage de type maintien des écrans LCD. La méthode proposée utilise des vecteurs de mouvement MPEG et des coefficients de fréquence de blocs DCT pour améliorer les flous de mouvement. Tout d’abord, nous avons interprété l’effet d’ouverture et de temps de réponse du LCD dans le domaine fréquentiel, puis modélisé des filtres de masque de netteté pour la compensation. Nous avons confirmé la réduction des flous de mouvement dans les écrans LCD grâce à un simulateur d'images animées.

Abstract: We proposed a method for reducing LCD motion blur in MPEG domain and analyzing the cause of LCD motion blur. The problem of LCD motion blur is caused by slow response time of liquid crystal and hold-type displaying method of LCDs. The proposed method uses MPEG motion vectors and frequency coefficients of DCT blocks to improve the motion blurs. First, we interpreted the aperture and response time effect of LCD in frequency domain then, modeled sharpening mask filters for the compensation. We confirmed the reduction of motion blurs in LCDs by a motion image simulator.
