Abstract

Lors d'une entrée d'informations qui partitionnent une région dans un dispositif d'entrée dans un état dans lequel une image d'utilisation de correction (950) est affichée, une ligne (800) qui représente une trace est affichée sur une unité d'affichage et l'image d'utilisation de correction (950) est partitionnée, la ligne (800) servant de frontière. Quand une région (801) est sélectionnée en tant que région de coupures, un soleil (911) qui est affiché entièrement sur une région (801) est effacé de l'image d'utilisation de correction (950). Sur l'unité d'affichage, une image d'utilisation de correction est affichée après une mise à jour (951). Selon d'autres instructions, les images mises à jour (image d'utilisation de correction (952) et image d'utilisation de correction (953)) sont affichées l'une après l'autre. L'image d'utilisation de correction (953) correspond à une image d'utilisation d'authentification et par conséquent, à l'endroit où l'image d'utilisation de correction (953) est affichée, le traitement d'utilisation d'authentification se termine.
