Title
(EN) SIGNAL PROCESSING DEVICE AND IMAGE DISPLAY APPARATUS INCLUDING THE SAME
(FR) DISPOSITIF DE TRAITEMENT DE SIGNAL ET APPAREIL D'AFFICHAGE D'IMAGE LE COMPRENANT
Abstract
(EN)
Disclosed is a signal processing device and an image display apparatus including the same. The signal processing device includes: a quality calculator configured to compare a previous frame image and at least a region of a current frame image, and calculate image type information based on a comparison result; an image quality setting unit configured to set an image quality based on the image type information; and an image quality processing unit configured to perform image quality processing according to the set image quality. Accordingly, it is possible to improve accuracy of image analysis and perform image quality processing according thereto.
(FR)
L'invention concerne un dispositif de traitement de signal et un appareil d'affichage d'image le comprenant. Le dispositif de traitement de signal comprend : un calculateur de qualité conçu pour comparer une image de trame précédente et au moins une région d'une image de trame courante, et pour calculer des informations de type d'image sur la base d'un résultat de comparaison ; une unité de définition de qualité d'image conçue pour définir une qualité d'image sur la base des informations de type d'image ; et une unité de traitement de qualité d'image conçue pour effectuer un traitement de qualité d'image conformément à la qualité d'image définie. Il est par conséquent possible d'améliorer la précision d'analyse d'image et d'effectuer un traitement de qualité d'image conformément à cette dernière.
