摘要 A visual axis detection apparatus in which an eye of an observer is illuminated by a light source, and the corneal reflection image of the eye and the reflected image of the iris are detected by a light sensor. By the utilization of the position information of each reflected image from the sensor, the visual axis of the eye is calculated by a calculator. The light sensor has a plurality of photoelectric elements, and the calculator utilizes the position information of one of a plurality of photoelectric elements which produces the smallest output signal to detect the reflected image of iris on the basis of the signal from the light sensor.
