To provide an occupant monitoring technique capable of preventing an alarm indicating that an occupant of a vehicle is in an abnormal state from being issued when in fact the occupant is in a normal state in which he or she can drive the vehicle.SOLUTION: An occupant monitoring device comprises: an image acquisition part 111 for acquiring a photographed image in which the interior of a vehicle is captured by an imaging device; a position adjustment part 116 for outputting an adjustment instruction for adjusting a position or an attitude of a control target device which is disposed inside the vehicle; an image processing part 115 which is capable of processing an image of an occupant included in the photographed image; a determination part 112 for determining whether or not a first face part is included in the image of the occupant; and a detection part 114 which, when it is determined that the first face part is not included in the photographed image, detects a position of a blocking object overlapping the first face part and blocking the first face part in the photographed image. On the basis of the detected position of the blocking object, it performs control using at least one of the position adjustment part and the image processing part and thereby adjusts the position of the control target device or processes the photographed image.SELECTED DRAWING: Figure 2

    【課題】車両の乗員が運転可能な正常状態であるにも拘らず異常状態であることを示す警報が発せられることを抑制できる乗員監視技術を提供すること。【解決手段】乗員監視装置は、撮像装置により車両の内部が撮像された撮像画像を取得する画像取得部111と、車両内に配置された制御対象装置の位置または姿勢を調整するための調整指示を出力する位置調整部116と、撮像画像に含まれる乗員の画像を加工することが可能な画像加工部115と、乗員の画像に第1の顔部位が含まれているか否かを判定する判定部112と、撮像画像に第1の顔部位が含まれていないと判定された場合、第1の顔部位と重なって前記第1の顔部位を遮蔽する遮蔽物の撮像画像における位置を検出する検出部114と、を備え、検出された遮蔽物の位置に基づいて位置調整部および画像加工部の少なくとも一方を用いた制御を行って、制御対象装置の位置を調整し又は撮像画像を加工する。【選択図】図2
