PROBLEM TO BE SOLVED: To provide a flicker value measuring device that can improve accuracy and the accuracy of measurement results.SOLUTION: A flicker value measuring device includes: two or more presentation units 1 that flash on and off in different frequency to each other, make each frequency change in the same direction, and present the light being equal in a time average of brightness to each other to a subject, respectively a detection unit 24 for detecting the point of time when the subject recognizes a change between continuity and discontinuity to the light exhibited by any of the two or more presentation units 1 an acquisition unit 25 for acquiring the frequency of the light recognized by the subject at the point of time detected by the detection unit 24 as a flicker value and an output unit 5 for outputting the flicker value acquired by the acquisition unit 25.COPYRIGHT: (C)2016,JPO&INPIT【課題】確度及び計測結果の精度を向上できるフリッカー値計測装置を提供する。【解決手段】フリッカー値計測装置は、互いに異なる周波数で点滅し、各周波数が同方向に変化し、輝度の時間平均が互いに等しい光を被験者にそれぞれ提示する複数の提示部1と、被験者が、複数の提示部1のいずれかにより提示された光に対して、連続的と非連続的との間の変化を認識した時点を検出する検出部24と、検出部24により検出された時点の、被験者が認識した光の周波数をフリッカー値として取得する取得部25と、取得部25により取得されたフリッカー値を出力する出力部5とを備える。【選択図】図1
