摘要
A corneal reflex position detection device includes a pupil detecting unit that detects the center position of the pupil from an image of an eye of a test subject; and a corneal reflex detecting unit that detects the corneal reflex area from the image. The corneal reflex detecting unit enlarges, in a stepwise manner, a detection target area with reference to the center position of the pupil, to detect whether or not a high-luminance area having the luminance to be equal to or greater than a luminance threshold value is present in the image; and, if the high-luminance area is detected, determines that the high-luminance area represents the corneal reflex area.
