A Linearized Model For Flicker And Contrast Thresholds At Various Retinal Illuminances, Albert Ahumada, Andrew B. Watson
MODVIS Workshop
Watson and Ahumada (1992 SID) predicted flicker thresholds for bright displays using a temporal contrast sensitivity function (TCSF). Under the assumptions that the falling limb of the TCSF is linear at all retinal illuminations and that the Ferry-Porter law can be extended to supra-threshold levels, the thresholds for any of the three variables (frequency in Hz, log10 contrast, and retinal illuminance in log Trolands) can be predicted from the other two from a linear model with four parameters.
