PROBLEM TO BE SOLVED: To provide a driver state monitoring device capable of more appropriately detecting an operating state of a driver.SOLUTION: A driver state monitoring device 1 for monitoring a state of a driver includes: a driver monitor camera 10 for imaging the driver; an abnormality diagnosing unit 33 for diagnosing the state of the driver or the driver state monitoring device based on an image transmitted from the driver monitor camera; and an alarm unit 40 for alarming the driver of abnormality when the abnormality diagnosis unit determines that the driver or the driver detection device is abnormal. The abnormality diagnosing unit is configured to determine that an abnormality occurs in the driver or the driver state monitoring device when at least a part of the image transmitted from the driver monitor camera has a change amount in a predetermined time period equal to or smaller than a predetermined change amount.SELECTED DRAWING: Figure 3
【課題】ドライバの運転状態をより適切に検出することができるドライバ状態監視装置を提供する。【解決手段】ドライバの状態を監視するドライバ状態監視装置1は、ドライバを撮像するドライバモニタカメラ10と、ドライバモニタカメラから送信された画像に基づいてドライバ又はドライバ状態監視装置の状態を診断する異常診断部33と、異常診断部によってドライバ又は当該ドライバ検出装置に異常が生じていると判定された場合にドライバに異常を警報する警報部40と、を備える。異常診断部は、ドライバモニタカメラから送信された画像の少なくとも一部について、所定時間における変化量が予め定められた変化量以下であった場合には、ドライバ又はドライバ状態監視装置に異常が生じていると判定するように構成される。【選択図】図3
