To provide a driver monitoring device which can determine whether or not a driver seats on a driving seat in a short time by quickly using seating sensors of seats other than the driving seat, when determining that the driver does not seat thereon on the basis of an image obtained by photographing the vicinity of the driving seat.SOLUTION: A driver monitoring device acquires the number of occupants riding on a vehicle when the vehicle starts to drive, determines whether or not the driver seats on a driving seat on the basis of an image in the vicinity of a driving seat of the vehicle photographed by an imaging part, determines that the driver does not seat on the driving seat in the case where the number of seat occupants indicating the number of seating persons detected by seating sensors arranged in each of seats other than the driving seat in the vehicle coincides with the number of riders, when determining that the driver does not seat on the driving seat, and determines that the driver seats on the driving seat in the case where the number of seat occupants is smaller than the number of riders by one.SELECTED DRAWING: Figure 3
【課題】運転席近傍が撮像された画像に基づいてドライバが運転席に着座していないと判定された場合には、すぐに運転席以外の座席の着座センサを用いることにより、短い時間でドライバが運転席に着座しているか否かを判定できるドライバ監視装置を提供する。【解決手段】ドライバ監視装置は、車両が走行を開始する際に車両に搭乗している搭乗者数を取得し、撮像部により撮像された車両の運転席近傍の画像に基づいて、ドライバが運転席に着座しているか否かを判定し、ドライバが運転席に着座していないと判定された場合、車両における運転席以外の座席のそれぞれに配置された着座センサにより検知された着座している人の数を表す着座者数が搭乗者数とが一致する場合にはドライバは運転席に着座していないと判定し、着座者数が搭乗者数よりも一人少ない場合にはドライバは運転席に着座していると判定する。【選択図】図3
