<p>The image of the visual field direction of the user of a head mounted display is captured by means of a CCD sensor (S11). From the captured image, a barcode is extracted (S12). From the barcode, a vehicle is identified (S13). When an image-capturing magnification ratio is a threshold magnification ratio or smaller (S14:NO), a real image is displayed (S17). When the image-capturing magnification ratio is larger than the threshold magnification ratio (S14: YES), an internal image corresponding to the real image is displayed (S15). The image-capturing magnification ratio can be set by the user. According to the image-capturing magnification ratio, the real image or the internal image is displayed on the head mounted display.</p> |
