PROBLEM TO BE SOLVED: To provide a technology capable of realizing a visual function inspection considering various optical environments including inspection time.SOLUTION: A visual function inspection system includes: visual function inspection means for executing a visual function inspection on a subject by sequentially presenting to the subject a target including a plurality of attention parts having degrees of brightness or stimulation values of color stimulation that differ from each other； and analysis means for calculating, on the basis of an inspection result by the visual function inspection means, a boundary between a region for which the subject has visibility and a region for which the subject has no visibility for each stimulation value of color stimulation in a coordination system representing correlation between a brightness contrast value between the degree of brightness of the attention parts and the degree of brightness of a background part and a brightness average value of the target including the attention parts and the background part.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT【課題】 検査時を含む多様な光環境を考慮した視機能検査を実現できる技術を提供することを目的とする。【解決手段】 複数の注目部分の輝度または色刺激の刺激値が互いに異なる視標を被験者に順次提示し、被験者に対する視機能検査を実行する視機能検査手段と、視機能検査手段による検査結果に基づいて、注目部分の輝度と背景部分の輝度との輝度コントラスト値と注目部分および背景部分を含む視標の輝度平均値との相関を示す座標系において、色刺激の刺激値毎に、被験者が視認性を有する領域と視認性を有しない領域との境界を求める分析手段とを有する。【選択図】 図１
