A suprathreshold ferry-porter law: Implications for the measurement of display flicker

Although there are many papers on the threshold detection of flicker, suprathreshold flicker effects have been relatively unstudied. In this paper, we present a psychophysical matching technique for measuring the magnitude of above-threshold flicker. We have used this technique to measure perceived flicker on CRT displays. Over the range of temporal modulations and luminances studied, we find that suprathreshold perceived flicker increases linearly with log pixel luminance. © SPIE.
