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
