To provide a device, a system, and a method for detecting a line of sight that can continuously and accurately detect the line of sight of a driver.SOLUTION: In a line-of-sight detector 1, when a processing unit 13 fails to detect an eye region 33 in an estimated eye part region 32 in a driver image 30, a notification unit 14 issues a notification that prompts specific actions including the opening/closing actions of one eye to be done. The processor 13 updates a position of the estimated eye part region 32 so as to include a change region 35 when the processor determines the existence of the changed change region 35 in driver images 30B and 30C after the notification with respect to a driver image 30A before the notification, and detects the eye region 33 in the updated estimated eye part region 32A.SELECTED DRAWING: Figure 6

    【課題】運転者の視線検出を継続的に精度良く行うことができる視線検出装置、視線検出システム、及び視線検出方法を提供する。【解決手段】視線検出装置1は、処理部13が、運転者画像30における推定眼部領域32内で眼領域33を検出できなかった場合、報知部14により片眼の開閉動作を含む特定の動作を促す内容の報知を行う。処理部13は、報知前の運転者画像30Aに対する報知後の運転者画像30B,30Cにおいて、変化した変化領域35があると判定したときは、当該変化領域35を含むように推定眼部領域32の位置を更新し、更新後の推定眼部領域32A内で眼領域33を検出する。【選択図】図6
