Device having sight line detecting function

Image Number 11 for United States Patent #6507702.

A device having a sight line detecting function includes an illumination unit for illuminating an eyeball of an observer looking into an observation screen, by a plurality of light-emitting members; an image-pickup member which receives the light reflected from the eyeball; a rotational angle calculating device which calculates the rotational angle of the eyeball of the observer, using the cornea reflection images detected by the image-pickup member; and a correction unit for calculating correction data for correcting error between the calculated rotational angle value and the sight line of the observer, and for storing the correction data. In this device, the correction unit stores a plurality of correction data corresponding to the number of the cornea reflection images, with respect to the same observer.
