摘要

Provided is a gaze position estimation system capable of estimating a gaze position of a user without detecting the center point of an iris or estimating the projection position of the center of an eyeball. A photographing unit (17) photographs a face of the user who is looking at a screen displayed on a display unit. An area detecting unit (32) detects, from the photographed image of the photographing unit (17), an eye area of the user and at least one of a face area of the user or a predetermined part area of the user other than eyes. An areal size/position information obtaining unit (60) obtains areal size information and position information of the eye area, and areal size information and position information of the at least one of the face area or the predetermined part area. A gaze position estimation unit (62) estimates a position in the screen that the user is gazing at, based on the areal size information and the position information that are obtained by the areal size/position information obtaining unit (60).
