Abstract
A method for measuring flicker fusion threshold. Set a measurement scheme, including setting N 8-shaped digital frames in a background light area that flickers within a set frequency. Set ten groups of different frequency combinations being applied to the N 8-shaped digital frames. Assign each frequency in each group of the frequency combinations with a stroke of the 8-shaped digital frame. Randomly select, for each of the N 8-shaped digital frames, one from the ten groups of the frequency combinations. Determine the value of each frequency in each group of frequency combinations in the N groups of frequency combinations. Recognize, by the subject, the flickering digits on the N 8-shaped digital frames in the background light area within the set frequency range. Determine the range of the flicker fusion threshold or the final flicker fusion threshold of the subject according to the result that can be seen by the subject.
