摘要

This point of gaze detection device detects a subject's gaze point in the peripheral environment and comprises: an eyeball image acquisition means for acquiring a subject's eyeball image; a gaze reflection point estimation image means for estimating, from the eyeball image, a first gaze reflection point at which light which has arrived from an optical axis direction of the subject's eyeball is reflected; a corrected gaze reflection point computation means for, on the basis of an individual parameter which denotes the difference between the line of sight direction of the subject and the optical axis direction of the eyeball, corrects the first gaze reflection point and computes a corrected gaze reflection point which is the corrected first gaze reflection point; and a point of gaze detection means for detecting the point of gaze on the basis of the light of the corrected gaze reflection point and the light of the peripheral environment.
