To provide an abnormality detection device which can simply and rapidly detect abnormality such as fall or a rapid squat of a person, that is, occurrence of a person's attitude abnormality.SOLUTION: The abnormality detection device detects the person's attitude abnormality through a position relation between a reference point PP1 of a total body image PE and an object point PP2 of a head image PH being an upper body image detected from a body in an image. Thus, by performing detection based on a relative position relation between the reference point PP1 of the total body image PE and the object point PP2 of the upper body image (head image PH), the person's attitude abnormality is detected, and further a dangerous state is determined.SELECTED DRAWING: Figure 3 【課題】人の転倒や急なうずくまり等の異常、すなわち人の姿勢異常の発生を簡易かつ迅速に検知できる異常検知装置を提供すること。【解決手段】異常検知装置は、画像中の人物について抽出した全身画像ＰＥの基準点ＰＰ１と上半身画像である頭部画像ＰＨの対象点ＰＰ２との位置関係から人の姿勢異常を検知する。これにより、全身画像ＰＥの基準点ＰＰ１と上半身画像（頭部画像ＰＨ）の対象点ＰＰ２との相対的な位置関係に基づく検知とすることで、人の姿勢異常の検知し、延いては危険状態の判定をする。【選択図】図３
