Abstract

A gaze detection apparatus includes at least one memory and at least one processor which function as: a gaze detection unit configured to detect, based on an eye image in which an eye of a user is imaged, a gaze position which is a position at which the user looks; an orientation detection unit configured to detect a head orientation which is an orientation of a head of the user, based on the eye image; a calibration unit configured to acquire a first correction value for reducing a detection error of the gaze position by a predetermined calibration operation; and a correction unit configured to correct the first correction value, based on gaze information related to a current gaze position, a head orientation during the predetermined calibration operation, and a current head orientation.
