PROBLEM TO BE SOLVED: To provide a state detection device capable of detecting a state of an object to be detected without attaching a sensor or the like to the object to be detected.SOLUTION: A state detection device comprises: an imaging part for imaging an object to be detected； a specific state detection part for detecting a specific state of the object to be detected on the basis of change of the object to be detected which is detected based on an imaging result of the imaging part； and a monitor notification part for notifying a monitor of a fact that the specific state is detected.SELECTED DRAWING: Figure 2【課題】被検対象にセンサなどを取り付けることなく被検対象の状態を検出可能な状態検出装置を提供する。【解決手段】被検対象を撮像する撮像部と、撮像部の撮像結果から検知した被検対象の変化に基づき被検対象の特定状態を検出する特定状態検出部と、特定状態が検出されたことを監視者に通知する監視者通知部と、を備える状態検出装置。【選択図】図２
