Abstract
A head-mounted display device captures an image of a real space as an external video through a circular fish-eye lens. A main image is extracted from a central portion of the external video, and a left image, a right image, an upper image, and a lower image are extracted as sub-images from the periphery of the external video. The distortion of a wide-angle lens is corrected in the main image, and the main image is displayed at the center. Each sub-image is displayed around the main image.
