Abstract:
1. A head mounted display comprising: an eyeglasses frame to be mounted to an observer's head; an image display device; an image sensing device mounted to the frame; and a correction section, wherein the image display device includes: wherein the correction section stores therein correction data including reference distance data corresponding to a predetermined range between the image sensing device and the reference object, obtained for correcting reference sensed image data, obtained through sensing an image of a reference object by the image sensing device, so that an image of the reference object observed through the optical device and a reference image outputted from the image generating device on the basis of the reference sensed image data and generated in the optical device are put into registration with each other, wherein the reference object is located in the line of sight and external to the outer surface of the head mounted display such that a distance between the reference object and a pupil of the observer is greater than a distance between the registered image and the pupil of the observer, and wherein the correction section corrects sensed image data obtained through sensing an image of an object other than the reference object by the image sensing device, on the basis of the correction data and a distance setting corresponding to a predetermined range between the imaging sensing device and the object other than the reference object, so that the image of the object other than the reference object observed through the optical device and the image outputted from the image generating device on the basis of the sensed image data and generated in the optical device are put into registration with each other.
