Abstract

L'invention concerne un appareil de traitement d'informations qui comprend : un moyen d'acquisition d'image de distance qui acquiert une image de distance d'un emplacement prédéterminé comprenant un lit; un moyen de détection qui, sur la base de l'image de distance, détecte une paire d'une partie de tête et d'une partie de corps d'une personne présente dans l'image de distance; et un moyen de détermination qui détermine que la paire détectée de la partie de tête et de la partie de corps indique une personne selon l'état de mouvement de la partie de tête et de la partie de corps. En outre, le moyen de détermination détermine la posture de la personne en fonction de la relation de position entre la paire de la partie de tête et de la partie de corps déterminée pour indiquer une personne.
