To appropriately detect the movement of the eyes of a subject.SOLUTION: A line-of-sight estimation system (10) comprises: display control means (101) that displays to move a fixation point (X) that a subject looks at so that a first period where the fixation point moves at a predetermined speed and a second period where the fixation point is stopped for a predetermined period are alternately repeated; detection means (102) that detects the movement of the eyes of the subject from an image of the subject; tracking determination means (110) that determines whether the eyes of the subject track the fixation point based on the movement of the eyes; and impersonation detection means (201) that detects impersonation of the subject based on a result of determination made by the tracking determination means.SELECTED DRAWING: Figure 1 【課題】対象者の目の動きを適切に検出する。【解決手段】視線推定システム（１０）は、対象者が注視する注視点（Ｘ）を、所定の速度で動く第１期間、及び前記注視点を所定期間停止する第２期間が繰り返して移動するように表示させる表示制御手段（１０１）と、対象者の画像から対象者の目の動きを検出する検出手段（１０２）と、目の動きに基づいて、対象者の目が注視点を追従しているか否か判定する追従判定手段（１１０）と、追従判定手段の判定結果に基づいて、対象者のなりすましを検出するなりすまし検出手段（２０１）とを備える。【選択図】図１
