Measured pupil diameter and estimation error of pupil models from the inter- and intrapersonal experiment with chromatic stimuli. (A) Pupil diameter at exposure times of 1 s, 60 s and 300 s from the interpersonal experiment with 20 subjects (Age: 19–25, Mean age: 22.2 SD ± 1.77 years). (B) Pupil diameter from the intrapersonal experiment with one 33-year-old observer and 12 repetitions. (C) The mean and standard deviation of the differences between the calculated pupil diameter of the models and the measured pupil diameter from the interpersonal experiment with twenty subjects. The ribbon shows the estimation error ± 0.5 mm as an indicator. (D) Mean and standard deviation of the estimation error from the intrapersonal experiment.
