ABSTRACT:
A reference image and an index image are displayed on a three-dimensional display device with either one of the images taken as a left eye image and the other image taken as a right eye image. When a movement command to move a display position of the index image is inputted by a person to be inspected in order that a predetermined reference position of the reference image and the display position of the index image coincide with each other, the display position of the index image is moved on the basis of the movement command. The amount of deviation of the index image from the reference position of the reference image is calculated by the person to be inspected visually recognizing that the reference position of the reference image and the display position of the index image coincide with each other when confirmation input indicating that the person to be inspected visually recognizes the coincidence is provided by the person to be inspected.
