PROBLEM TO BE SOLVED: To detect an abnormal state of a driver easily without using a biological information sensor.SOLUTION: A driver state detector comprises: an imaging unit which is provided in an interior of a vehicle and captures an image of a driver; a posture determination unit for determining a parietal angle, which is an inclination angle to a vertical direction of a linear line connecting a lumbar part and a parietal part of a driver, from the image of the driver captured by the imaging unit; a storage unit for storing a first threshold angle on a front inclination side and a second threshold angle on a rear inclination side which are predetermined; and a state determination unit for, when the parietal angle of the driver is outside a range from the first threshold angle on the front inclination side to the second threshold angle on the rear inclination side, determining that the driver is in an abnormal state.SELECTED DRAWING: Figure 1

    【課題】生体情報センサを用いることなく、簡易に運転者の異常状態を検出する。【解決手段】ドライバ状態検出装置は、車両の室内に配置され、運転者を撮像する撮像部と、撮像部により撮像された運転者の画像から、運転者の腰部と頭頂部とを結ぶ直線の鉛直方向に対する傾斜角である頭頂角を判定する姿勢判定部と、予め定められた前傾側の第1閾値角度及び後傾側の第2閾値角度を保存する記憶部と、運転者の頭頂角が前傾側の第1閾値角度から後傾側の第2閾値角度までの範囲外のときは、運転者が異常状態になっていると判定する状態判定部と、を備える。【選択図】図1
