ABSTRACT:
An eye movement analysis system illuminates the surface of each eye, and calculates the movement of the eye from the image of the eye including the pupil and iris striation. The eye movement analysis system is made up of an image signal processor including a controller which calculates the movement of the eye as well as the respective positions of the center of the eye and the iris striation from the image of the eye and a RAM which holds the respective positions of the center of the eye and the iris striation, a display which displays the iris striation in different states before and after the positional analysis, and an operating section which stops changing the frame if the currently displayed iris striation is different from the previously specified iris striation.
