To provide an occupant observation device which can keep the accuracy of a state estimation of an occupant high.SOLUTION: An occupant observation device includes an imaging part which takes an image of the head of an occupant in a vehicle, an eye detection part which detects at least a part of an eye of the occupant in the image taken by the imaging part, a mouth detection part which detects at least a part of the mouth of the occupant in the image taken by the imaging part, and a state estimation part which estimates a state of the occupant on the basis of a detection result of the eye detection part and a detection result of the mouth detection part. The state estimation part changes a ratio of reflecting each of the detection result of the eye detection part and the detection result of the mouth detection part in the state of the occupant on the basis of a result of processing which is carried out based on the detection result of the eye detection part or the detection result of the mouth detection part.SELECTED DRAWING: Figure 1

    【課題】乗員の状態推定の精度を高く維持することができる乗員観察装置を提供すること。【解決手段】車両の乗員の頭部を撮像する撮像部と、前記撮像部により撮像された画像において、少なくとも前記乗員の眼の一部を検出する眼検出部と、前記撮像部により撮像された画像において、少なくとも前記乗員の口の一部を検出する口検出部と、前記眼検出部の検出結果と前記口検出部の検出結果とに基づいて前記乗員の状態を推定する状態推定部と、を備え、前記状態推定部は、前記眼検出部の検出結果または前記眼検出部の検出結果に基づいて行われる処理の結果に基づいて、前記眼検出部の検出結果と前記口検出部の検出結果とのそれぞれを前記乗員の状態の推定に反映させる割合を変更する、乗員観察装置。【選択図】図1
