To suppress erroneous determination of abnormality of a driver when diagnosing the abnormality of the driver.SOLUTION: A driver monitor system 1 comprises: an imaging apparatus 10 which picks up a face image of a driver; and a control device 20 to which the face image is transmitted. The control device includes: a face direction angle detection part 21 for detecting a roll angle of a face direction of the driver on the basis of the face image that is picked up by the imaging apparatus; an abnormality diagnosis part 22 which determines that there is abnormality in the driver in a case where an absolute value of the roll angle of the face direction is maintained equal to or more than a predetermined angle for a predetermined time or longer; and a change degree detection part 23 which detects a change degree of a face of the driver on the basis of the face image. Even while the absolute value of the roll angle of the face direction is maintained equal to or more than the predetermined angle for the predetermined time and longer, in a case where the change degree of the face of the driver that is detected by the change degree detection part is equal to or more than a predetermined reference, the abnormality diagnosis part determines that there is no abnormality in the driver.SELECTED DRAWING: Figure 5

    【課題】ドライバの異常診断を行うにあたり、ドライバの異常を誤判定してしまうのを抑制する。【解決手段】ドライバモニタシステム1は、ドライバの顔画像を撮像する撮像装置10と、この顔画像が送信される制御装置20と、を備える。制御装置は、撮像装置によって撮像された顔画像に基づいてドライバの顔向きのロール角を検出する顔向き角度検出部21と、顔向きのロール角の絶対値が所定時間以上に亘って所定角度以上に維持されるときにはドライバに異常があると判定する異常診断部22と、顔画像に基づいてドライバの顔の変化度合いを検出する変化度合い検出部23と、を備える。異常診断部は、顔向きのロール角の絶対値が所定時間以上に亘って所定角度以上に維持されているときであっても、変化度合い検出部によって検出されたドライバの顔の変化度合いが所定の基準以上である場合には、ドライバに異常はないと判定する。【選択図】図5
