1. A binocular measurement method comprising:
detecting light from a right eye and a left eye of a target person, and outputting detection signal of the light;
calculating a first feature amount corresponding to the right eye and a second feature amount corresponding to the left eye based on the detection signal; and
calculating, based on the first feature amount and the second feature amount, a comparison value obtained by comparing the first feature amount and the second feature amount,
wherein calculating includes calculating feature amounts related to eye blinking as the first feature amount and the second feature amount, and
wherein calculating includes calculating the feature amounts related to eye blinking by
(i) calculating a temporal change of an upper eyelid position and a temporal change of an upper eyelid movement speed for each of the right eye and the left eye, separately, and
(ii) calculating the feature amount related to eye blinking for each of the right eye and the left eye, separately, based on the calculated temporal change of the upper eyelid position and the calculated temporal change of the upper eyelid movement speed.
