PROBLEM TO BE SOLVED: To provide a state detection device and a state detection method for highly accurately detecting the state of a target person.SOLUTION: The state detection device includes: a detection part for analyzing an image obtained by picking up the image of a target person which is present on or around a bed to detect the moving direction of the target person a first determination part for determining a state including the presence/absence of the existence of a caregiver who cares the target person on the basis of the image in a predetermined range near the bed included in the image a second determination part for determining the state of each safety device on the basis of at least either an image showing the state of at least one safety device installed in the bed included in the pickup image or notification from each safety device showing the mounted state of each safety device a determination part for determining a state relating to the current safety of the target person on the basis of the moving direction of the target person detected by the detection part, the past state of the target person, information showing the state of the caregiver and information showing the state of each safety device and an output part for outputting the information showing the current state of the target person obtained by the determination part.COPYRIGHT: (C)2013,JPO&INPIT【課題】対象者の状態を高い精度で検知することが可能な状態検知装置および状態検知方法を提供する。【解決手段】ベッド上あるいはベッドの近傍にいる対象者を撮像した画像を解析することにより、対象者の移動方向を検出する検出部と、画像に含まれるベッドの近傍の所定の範囲の画像に基づいて、対象者を介助する介護者の存在の有無を含む状態を判別する第1判別部と、撮像した画像に含まれるベッドに設けられた少なくとも一つの安全装置の状態を示す画像と各安全装置の装着状態を示す各安全装置からの通知との少なくとも一方に基づいて、各安全装置の状態を判別する第2判別部と、検出部によって検出された対象者の移動方向と、対象者の過去の状態と、介護者の状態を示す情報と、各安全装置の状態を示す情報とに基づいて、対象者の現在の安全性に関する状態を判断する判断部と、判断部で得られた対象者の現在の状態を示す情報を出力する出力部とを備える。【選択図】 図1
