Abstract

La présente invention concerne un dispositif d'imagerie. Le dispositif d'imagerie comprend une unité de balayage pour balayer une zone d'interface du dispositif d'imagerie ; une unité de notification pour notifier à un opérateur des informations indiquant la présence ou l'absence d'un objet sur la zone d'interface ; et un contrôleur, couplé à l'unité de balayage et à l'unité de notification, pour commander l'unité de balayage pour balayer la zone d'interface après l'achèvement d'une tâche d'opération par rapport à l'objet sur la zone d'interface, déterminer, pour chaque bloc balayé dans l'interface, si un nombre total de zones non blanches consécutives dans le bloc balayé a atteint une valeur prédéterminée, marquer le bloc balayé en tant que bloc cible si la valeur prédéterminée est atteinte, déterminer si un certain nombre des blocs cibles a atteint un seuil prédéterminé, et commander l'unité de notification pour notifier à l'opérateur des informations indicatives de l'objet restant sur la zone d'interface si le seuil prédéterminé est atteint.
