1. A head-mounted display for allowing observation of a display image through an eyepiece lens for enlarging a user's viewing angle, comprising:
an image acquiring section for acquiring data of the display image that is given a reverse distortion to reverse an image distortion caused by the eyepiece lens;
a reprojection section operating to correct chromatic aberration in the reverse distorted display image as a function of a distortion coefficient of the eyepiece lens that is unique to the head-mounted display; and
a display section for outputting the corrected display image, wherein:
the image acquiring section and the reprojection section operate to perform a first correction as an initial step to correct the image distortion, followed by a second correction to separately correct the chromatic aberration in the reverse distorted display image, and
the first correction and the second correction are performed independent of, and a display frame rate is adjusted independently of, the generation of the display image.
