Abstract

PURPOSE: To enable highly accurate calculation of eye sight of an observer by selecting specified two from a plurality of photoelectric element array to obtain information based on a cornea reflection image and an iris reflection image from the two photoelectric element array.
CONSTITUTION: Luminous fluxes from infrared light emitting diodes 5a and 5b arranged being separated in the way of a photoelectric element array 6 form cornear reflection images (e) and (d) individually in a Z axis. As an interval between the cornea reflection images (e) and (d) varies corresponding to a distance between the infrared light emitting diodes and eyeballs of an observer, reading of image signals of the photoelectric element array 6 is performed sequentially to detect a photoelectric element array Yp' in which cornear reflection image e' and d' are formed again and positions Zd' and Ze' of generation thereof in the way of the array to determine an image formation multiplying factor B from the interval. Moreover, field of view points Z2b' and Z2a' of iris 23 and pupil 24 are detected on the photoelectric element array Yp' to calculate the length of the pupil on the photoelectric element array Yp'. Then, another photoelectric element array Y1' of an image signal is calculated from the image formation multiplying factor and a value of the length of pupil. When detected, field of view points Z1a' and Z1b' of the iris 23 and the pupil 24 on the photoelectric element array Y1' can be used to calculate eye sight.
