Pupillary light reflex measurement device, light reflex measurement method, and light reflex measurement program

摘要

PROBLEM TO BE SOLVED: To provide a light reflex measuring device, a light reflex measuring method, and a pair, which can accurately detect light reflex by emitting light at an optimum timing when the line of sight is directed to the light source side with respect to the pupil of a subject. Provides a light reflex measurement program. SOLUTION: The light reflex measuring device includes a light source that emits light when a predetermined condition is satisfied, a pupil image acquisition device that acquires an image of the pupil of a subject, and a line-of-sight detection unit that detects the line of sight of the subject. , A control unit that emits light from a light source when the line-of-sight detection unit detects that the subject's line of sight is directed to the effective area, and measures the subject's pupil diameter based on the image acquired by the pupil image acquisition device.
