Title (EN) DISPLAY APPARATUS AND IMAGE PROCESSING METHOD THEREOF
(FR) DISPOSITIF D'AFFICHAGE ET PROCÉDÉ DE TRAITEMENT D'IMAGE ASSOCIÉ
Abstract:
(EN) A display apparatus is provided. The display apparatus includes an input interface, a first storage, a display, and a processor. Pixel values corresponding to a predetermined number of lines in an image input through the input interface are stored in the first storage,. The processor acquires a first patch of a predetermined size by sampling a number of pixel values located in an outer region of a matrix centering about a specific pixel value from among the pixel values stored in the first storage, acquires a high-frequency component for the specific pixel value based on the acquired first patch, and processes the input image based on the high-frequency component. The display displays the processed image.
(FR) L'invention concerne un dispositif d'affichage. Le dispositif d'affichage comprend une interface d'entrée, une première mémoire, un écran d'affichage, et un processeur. Des valeurs de pixels correspondant à un nombre prédéterminé de lignes dans une entrée d'image par l'intermédiaire de l'interface d'entrée sont stockées dans la première mémoire. Le processeur acquiert une première pièce d'une taille prédéterminée par échantillonnage d'un certain nombre de valeurs de pixels situées dans une région externe d'une matrice centrée autour d'une valeur de pixel spécifique parmi les valeurs de pixels stockées dans la première mémoire, acquiert une composante haute fréquence pour la valeur de pixel spécifique sur la base de la première pièce acquise, et traite l'image d'entrée sur la base de la composante haute fréquence. L'écran d'affichage affiche l'image traitée.
