Abstract

Le dispositif de commande de l'affichage d'image de texte ci-décrit évite que les images de caractères de texte ne deviennent difficiles à distinguer quand on les grossit. Les images de caractères de texte qui sont incluses dans une image de texte sont extraites puis disposées pour être affichées sur l'écran d'un téléphone mobile. Lorsqu'une instruction de grossissement et un taux de grossissement sont fournis au téléphone mobile, une vérification est effectuée pour déterminer si la taille des images de caractères de texte respecte une limite de taille admissible quand lesdites images sont grossies selon le taux de grossissement fourni (étape 36). Lorsque la limite admissible est dépassée (« NON » à l'étape 36), les bords des images de caractères de texte grossies deviennent très visibles et rendent lesdites images difficiles à distinguer. En mode arrêt, les images de caractères de texte sont grossies jusqu'à la taille limite admissible (étape 41) et ne sont pas agrandies jusqu'à atteindre une taille qui dépasse la limite admissible. Les images de caractères de texte qui ont été grossies jusqu'à la limite de taille admissible sont redisposées et affichées sur l'écran (étapes 38 et 39).
