Abstract:
This correction method comprises: acquiring, by means of a processing circuit of a head-mounted display, projection angles via a photographic lens of dots of a correction test pattern corresponding to dots of a reference test pattern, the angle being calculated on the basis of the correction test pattern obtained by photographing the reference test pattern with the photographic lens through a correction lens that corrects the user's visual characteristics, the reference test pattern including one dot placed at a reference point and at least one dot placed on each of a plurality of straight lines extending in different directions from the reference point; and correcting, by means of the processing circuit, distortion in a virtual space image caused by the adjustment lens on the basis of projection angles corresponding to the dots of the reference test pattern.
