An occupant observation device which can maintain a high precision in occupant state estimation. The device includes an imager configured to capture an image of a head of an occupant of a vehicle; aneye detector configured to detect at least a part of eyes of the occupant in an image captured by the imager; a mouth detector configured to detect at least a part of the mouth of the occupant in theimage captured by the imager; and a condition estimater configured to estimate a condition of the occupant on the basis of a detection result of the eye detector and a detection result of the mouth detector, in which the condition estimater changes a ratio of reflecting each of the detection result of the eye detector and the detection result of the mouth detector in an estimation of the conditionof the occupant, on the basis of the detection result of the eye detector or a result of a process performed on the basis of the detection result of the eye detector. 本发明提供一种能够将乘员的状态推定的精度维持得高的乘员观察装置。乘员观察装置具备：摄像部，其拍摄车辆的乘员的头部；眼睛
