The head mount part 110 includes a display board located in front of one eye of the subject, and an imaging device located in front of the other eye of the subject. The subject is examined whether or not capable of visually recognizing any of multiple light sources that is lit in order of arrangement on the display board. The imaging device captures an image of the other eye of the subject, when each light source is lit, detects how far the visual axis of the other eye moves from a prescribed reference point, and generates shift information. An image, the position of which has been corrected by the shift information is generated as an examination result. |
