PROBLEM TO BE SOLVED: To appropriately examine a visual function of a subject.SOLUTION: A visual function detection device includes: a display control unit for causing an image 231 for determination to be displayed in a display region 101T on a display screen 101S of a display unit, and causing the position of the image 231 for determination to be moved continuously； a fixation point detection unit for detecting the position of a fixation point of a subject observing the display screen 101S； a positional relationship detection unit for detecting a positional relationship between the position of the image 231 for determination on the display screen 101S and the position of the fixation point； and a visual function detection unit for detecting a visual function of the subject H on the basis of the positional relationship.SELECTED DRAWING: Figure 14COPYRIGHT: (C)2019,JPO&INPIT【課題】被験者の視機能を適切に検査する。【解決手段】視機能検出装置は、表示部の表示画面１０１Ｓ上の表示領域１０１Ｔに判断用画像２３１を表示させ、判断用画像２３１の位置を連続的に移動させる表示制御部と、表示画面１０１Ｓを観察する被験者の注視点の位置を検出する注視点検出部と、表示画面１０１Ｓ上の判断用画像２３１の位置と、注視点の位置との位置関係を検出する位置関係検出部と、位置関係に基づき、被験者Ｈの視機能を検出する視機能検出部と、を有する。【選択図】図１４
