PROBLEM TO BE SOLVED: To accurately measure rotation of an eyeball.SOLUTION: An eyeball measurement system includes: an image acquisition section which acquires a first pupil image obtained by photographing the eye of an object person, and a second pupil image obtained by photographing the eye after having obtained the first pupil image; a contour calculating section which subjects each of the first pupil image and the second pupil image to processing of calculating the contour of the pupil; an angle calculating section which calculates a rotation angle around a visual line of the eyeball of the object person based on a positional relationship between the contour of the pupil obtained from the first pupil image and the contour of the pupil obtained from the second pupil image.SELECTED DRAWING: Figure 4
