To provide a glare perception examination device capable of quantitatively examining a user's glare perception.SOLUTION: A glare perception examination device 1 performs evaluation using a display pattern which has a predetermined color as a background color, and in which first patches formed in a first color having the luminance higher than that of the background color by a preset luminance and second patches formed in a second color having the luminance lower than that of the background color by a preset luminance are arranged randomly, and the first patches and the second patches are arranged so that the total area of the first patches and the total area of the second patches are equal to each other in the display pattern.SELECTED DRAWING: Figure 1 【課題】定量的にユーザのグレア知覚を検査できるグレア知覚検査装置を提供する。【解決手段】グレア知覚検査装置１は、所定の色を背景色とする表示パターンであって、背景色の輝度よりも予め設定された輝度だけ高くした第１色で形成された第１パッチと、背景色の輝度よりも予め設定された輝度だけ低くした第２色で形成された第２パッチと、をランダムに配置し、且つ、表示パターン内において第１パッチの合計面積と第２パッチの合計面積とが互いに等しくなるように配置して構成される表示パターンを用いて評価する。【選択図】図１
