Abstract

La présente invention supprime une diminution de la visibilité d'une image de contenu due à un effet de luminescence. Un processeur affiche une ou plusieurs images luminescentes G affichées au moins dans les directions gauche et droite d'une image de contenu FU et ne présentant pas un contour clair, affiche une première image de contenu (FU1) présentant une première longueur αf10 dans une direction latérale et une seconde image de contenu (FU2) présentant une deuxième longueur αf20 plus courte que la première longueur αf10 dans la direction latérale et représentée à une distance supérieure à la première image de contenu telle que vue depuis un observateur simultanément ou à différents moments, affiche une première image luminescente G1 présentant une troisième longueur αg10 et affichée dans les directions gauche et droite de la première image de contenu FU1, affiche une seconde image luminescente G2 présentant une quatrième longueur αg20 et affichée dans les directions gauche et droite de la seconde image de contenu FU2, et définit la longueur entre une extrémité gauche et une extrémité droite de l'image luminescente G de telle sorte que αg20/αf20 < αg10/αf10 soit vérifié.
