A plurality of optical systems are provided which improve the feelings of presence at sites obtained from various images through a single lens camera by use of optical parts but not by expanding the image plane. These optical systems are characterized in that by use of division, reflection or refraction of light, combination of them, or two duplicated images, a virtual image is formed in the left eye more leftward than the position of the image as viewed by the naked eye and in the right eye more rightward than the position of the image as viewed by the naked eye, or ideally directly in front of each of the eyes, so that parallax is reduced to or approaches zero. |
