To provide a consciousness determination device capable of determining consciousness even from a face image in which an eye region of a driver of a vehicle is not appropriately included.SOLUTION: A consciousness determination device includes: a detection unit that detects a face region in which a face of a driver is represented from a face image obtained by photographing the face of the driver of a vehicle and a hand region in which a hand of the driver is represented; and a determination unit for determining that consciousness of the driver is lowered when a ratio of the face image in which distance between the face region and the hand region is smaller than a distance threshold is larger than a determination threshold in a plurality of face images obtained in time series.SELECTED DRAWING: Figure 6

    【課題】車両の運転者の目領域が適切に含まれない顔画像からも覚醒度を判定することができる覚醒度判定装置を提供する。【解決手段】覚醒度判定装置は、車両の運転者の顔を撮影した顔画像から、運転者の顔が表された顔領域と、運転者の手が表された手領域とを検出する検出部と、時系列に得られた複数の顔画像において、顔領域と手領域との間の距離が距離閾値よりも小さい顔画像の割合が判定閾値より大きい場合に、運転者の覚醒度が低下したと判定する判定部と、を備える。【選択図】図6
