PROBLEM TO BE SOLVED: To image an eye ball when is impossible for the subject localize eye ball image and impossible to take an image whole of eye ball, by setting a lighting part, which irradiates visible rays, an imaging part, which images the reflected image that is reflected in the subject's eye ball, and a power source on an obstacle. SOLUTION: A blinker 11, which is mounted on the eye ball of horse, is glued on the mask, which covers the head part, encloses more than half of the surface of eye ball 10 with a hemispherical cover. An imaging part 23 is mounted on the surface of blinker 11 to make an optical axis 12 of camera 20 place on the eyeball 10. A light 21, which irradiates the eyeball 10, is placed on the blinker 11 surrounding the camera 20. It is used the non-visible rays, such as infrared ray, as an irradiation light, so as not to fell dazzling for the subject. For the eye ball 10, the eye print is irradiated from the around with the light 21, and the non-visible rays, which is irradiated from the light 21, passes through cornea 15, iris 16 and pupil 17, then it is scattered at each part of retina 18. A part of scattered non-visible rays is reflected then it goes to the imaging part 23 direction and the image of eyeball is taken. |
