Flicker detection

As long as the modulation frequency is kept above the fusion threshold, the perceived intensity can be changed by changing the relative periods of light and darkness. One can prolong the dark periods and thus darken the image; therefore the effective and average brightness are equal. This is known as the Talbot-Plateau law. Like all psychophysical thresholds, the flicker fusion threshold is a statistical rather than an absolute quantity. There is a range of frequencies within which flick… WebThe TCS3408 Evaluation Kit comes with everything needed to evaluate the TCS3408 ALS/Color and Flicker detection sensor.
