To provide a driver state determination device that can precisely detect information on a driver's facial color and a state of a diver driving a vehicle while reducing a processing load of a CPU.SOLUTION: A driver state determination device includes: a visible light image acquisition unit configured to acquire a visible light image taken by a visible light camera that takes an image of a driver's face; a first state determination unit configured to determine a state of the driver based on the visible light image; a near infrared image acquisition unit configured to acquire a near infrared image taken by a near infrared camera that takes an image of the driver's face; a second state determination unit configured to determine a state of the driver based on the near infrared image; a vehicle traveling state determination unit configured to determine whether a vehicle is traveling or is stopped; and a power supply control unit configured to, when the vehicle is stopped, turn a power supply of the visible light camera on and turn a power supply of the near infrared camera off and configured to, when the vehicle is traveling, turn the visible light camera off and turn the near infrared camera on.SELECTED DRAWING: Figure 1
【課題】CPUの処理負荷を抑えつつ、運転者の顔色の情報および車両走行中の運転者の状態を精度よく検出することができる運転者状態判定装置を提供する。【解決手段】運転者の顔を撮像する可視光カメラの撮像した可視光画像を取得する可視光画像取得部と、可視光画像に基づいて運転者の状態を判定する第1の状態判定部と、運転者の顔を撮像する近赤外線カメラの撮像した近赤外線画像を取得する近赤外線画像取得部と、近赤外線画像に基づいて運転者の状態を判定する第2の状態判定部と、車両が走行状態か停車状態かを判定する車両走行状態判定部と、車両が停車状態の場合は、可視光カメラの電源をON、近赤外線カメラの電源をOFFの状態にし、車両が走行状態の場合は、可視光カメラをOFF、近赤外線カメラの電源をONの状態にする電源制御部と、を備えた。【選択図】図1
