An image (C) at a distant point and an image (D) at a close point for generating depth perception of a subject are displayed on an image display monitor (5), and eye movement of the subject at that time is detected by an eye movement detecting portion (2). A calculating portion (1) removes saccade component by using velocity and acceleration of the detected eye movement and calculates amplitude of vergence eye movement, change in convergence angle and cross-correlation of velocity or acceleration of the left and right eye movement to determine depth perception of the subject.
