Summary:To increase the likelihood of estimation of an abnormality in the posture of a driver of a movable body performed based on an image acquired by an imaging apparatus.SOLUTION: A nose feature point NS and a left shoulder feature point LS in a driver 30 captured in an image IM are specified. The distance d between the nose feature point NS and the left shoulder feature point LS in the vertical direction of a movable body is specified. When the amount of reduction of the distance d exceeds a threshold, it is estimated that the posture of the driver 30 is abnormal.SELECTED DRAWING: Figure 8 【課題】撮像装置により取得された画像に基づいてなされる移動体の運転者の姿勢異常の推定の確からしさを高める。【解決手段】画像ＩＭに写り込んだ運転者３０における鼻特徴点ＮＳと左肩特徴点ＬＳが特定される。移動体の上下方向における鼻特徴点ＮＳと左肩特徴点ＬＳの間の距離ｄが特定される。距離ｄの減少量が閾値を上回る場合、運転者３０の姿勢が異常であると推定される。【選択図】図８
