PROBLEM TO BE SOLVED: To objectively measure the degree of strabismus by an apparatus wherein when a person to be examined recognizes visually that the standard position of a standard image coincides with the displaying position of an indication image, a confirmative input for indicating it is performed by the person to be examined and the amt. of deviation of the indication image to the standard position of the standard image is calculated. SOLUTION: A three-dimensional display apparatus decomposes transferred scale- reduced image 30L for the left eye and scale-reduces image 30R for the right eye respectively into vertically long narrow tablet-like images and the narrow tablet-like image 31L for the left eye and the narrow tablet-like image 31R for the right eye are displayed on a liq. crystal panel 41 by arranging them alternately in the horizontal direction. In addition, a condition where only an image of a cage can be seen by the left eye of a subject and only an image of a lion can be seen by the right eye of the subject is realized and the image of the lion is moved on the displaying face for the subject and the displaying face for an examiner based on the direction and the amt. of movement by a mouse of an input device to calculate the amt. of deviation between the image of the cage and the image of the lion. It is possible thereby to measure objectively the degree of strabismus. |
