Abstract
In a sight line vector detecting system comprising: an infrared light source for illuminating either an eye or a face; a camera for photographing either the eye or the face; and a computer for processing photographed image data of said camera so as to calculate a sight line vector, the computer includes an image processing unit for detecting the true luminance point and the center of the pupil from the photographed image data; and a calculating unit for calculating the sight line vector; and the image processing unit performs such a processing operation that the image processing unit determines a luminance point capable of satisfying a predetermined requirement as the true luminance point among luminance points having the pupils at near places, calculates a center of the pupils, and further, calculates a center of a cornea ball.
