A method for displaying on a display medium an image corresponding to detected exposures of a plurality of pixels converted to a matrix having n rows and m columns of digital values. The method comprises creating a weighted, smoothed, subtracted matrix (10), adding the weighted, smoothed, subtracted matrix (11) to the starting matrix to produce an enhanced matrix (12); and then using the digital values from the enhanced matrix to display an image. A program storage device for carrying out the method, a digital x-ray image data capture system, and a method of using the system of this invention are also claimed.

L'invention concerne un procédé d'affichage sur un support d'affichage d'une image correspondant à des expositions détectées de plusieurs pixels convertis en une matrice présentant n rangées et m colonnes de valeurs numériques. Ledit procédé consiste à créer une matrice soustraite lissée et pondérée (10), à ajouter ladite matrice (11) soustraite, lissée et pondérée à la matrice de départ, de sorte qu'une matrice améliorée soit produite (12), et à utiliser les valeurs numériques de la matrice améliorée pour l'affichage d'une image. Un dispositif de stockage d'image permettant la mise en oeuvre du procédé, un système de capture de données d'image et un procédé d'utilisation du système de l'invention sont également décrits.
