To presume a visual field abnormal state in which either of right and left visual fields is abnormal.SOLUTION: A saccade detection unit (301) detects a saccade of a subject. A presumption unit (302) presumes that the subject is in a visual field abnormal state in which either of right and left visual fields is abnormal when both of a first condition that a difference (dLR) between an amplitude of the saccade in the right visual field and an amplitude of the saccade in the left visual field of the subject in a presumption period (P1) is equal to or greater than an amplitude difference threshold value (dLRth), and a second condition that a difference (fLR) between a frequency of the saccade in the right visual field and a frequency of the saccade in the left visual field of the subject in the presumption period (P1) is equal to or greater than a frequency difference threshold value (fLRth) are satisfied.SELECTED DRAWING: Figure 13

    【課題】視野の左右の片側が異常となる視野異常状態を推定する。【解決手段】サッケード検出部(301)は、対象者のサッケードを検出する。推定部(302)は、推定期間(P1)内の対象者の右視野内のサッケードの振幅と左視野内のサッケードの振幅との差(dLR)が振幅差閾値(dLRth)以上であるという第1条件および推定期間(P1)内の対象者の右視野内のサッケードの頻度と左視野内のサッケードの頻度との差(fLR)が頻度差閾値(fLRth)以上であるという第2条件の両方が成立する場合に、対象者の状態が視野の左右の片側が異常となる視野異常状態であると推定する。【選択図】図13
