A camera is arranged at a conjugate position to eyes of the observer. A distance from the observer to a pixel in the real space image located at the same position as a pixel in the virtual space image is determined according to the real space image picked up by the camera. A virtual space image is generated based on virtual space information stored beforehand. Then, the distance of the real space image is compared with that of the virtual space image, and one of the pixels more near the observer is selected for the display. This processing is performed on each pixel, and the real space image and the virtual space image are integrated as an image to be displayed for the observer at the same time.
