To provide an occupant monitoring device and an occupant monitoring system that improve reliability of an alarm output when inadvertent conditions such as dozing are detected.SOLUTION: In an occupant monitoring device 10, when a drowsiness determination unit 7 determines that a driver D is in a drowsiness state that causes a problem during driving based on an image captured by an image capturing unit 1 and a predetermined determination reference, an alarm is outputted by an alarm unit 21 and a basis image that is a basis of the alarm output is stored in an image storage unit 3. After that, when an input reception unit 9 accepts a reproduction request input made by the driver D, the image stored in the image storage unit 3 is reproduced by an image reproducing unit 11 and is displayed on a display unit 23. Further, when the driver D who sees this reproduced image determines that the alarm output is inappropriate, and the input reception unit 9 accepts the inappropriate intention input made by the driver D, a basis adjustment unit 12 adjusts the determination reference so as to suppress the output of the alarm.SELECTED DRAWING: Figure 1
【課題】居眠りなどの不注意状態の検出時に出力される警報の信頼性を高める。【解決手段】乗員監視装置10では、撮像部1で撮像された画像と所定の判定基準とに基づいて、運転者Dが運転に支障をきたす眠気状態にあると眠気判定部7が判定すると、警報部21により警報が出力されるとともに、警報出力の根拠となった根拠画像が画像記憶部3に記憶される。その後、運転者Dが行った再生要求入力を入力受付部9が受け付けると、画像記憶部3に記憶された画像が、画像再生部11により再生され表示部23に表示される。さらに、この再生画像を見た運転者Dが、警報出力が不適切であると判断した場合に、運転者Dが行った不適切意思入力を入力受付部9が受け付けると、基準調整部12が、警報の出力を抑制するように判定基準を調整する。【選択図】図1
