Ledit procédé d'affichage consiste à : diviser un panneau d'affichage à haute résolution en une pluralité de sous-régions, chaque sous-région correspondant à un numéro de série unique ; collecter une image des yeux d'un observateur humain ; reconnaître une première position à laquelle les pupilles des yeux sont situées ; déterminer une seconde position, sur le panneau d'affichage à haute résolution, correspondant à la première position ; selon la seconde position et un rayon R de focalisation des yeux, déterminer une sous-région requise pour être traitée avec précision sur le panneau d'affichage à haute résolution, et délivrer en sortie un numéro de série en tant que paramètre de la région ; et selon la paramètre de la région, effectuer un traitement d'étirage sélectif sur un signal d'entrée d'une image à une première résolution afin d'obtenir un signal d'une image à une seconde résolution ayant une résolution supérieure à celle du signal d'image à la première résolution, et afficher le signal obtenu sur le panneau d'affichage à haute résolution. Les modes de réalisation de la présente invention peuvent manifestement réduire les exigences pour la vitesse et le matériel de traitement de données d'image, ce qui permet d'obtenir une réduction des coûts de dispositifs d'affichage à haute résolution.
