PURPOSE:To enable three-dimensional vision and the use of information based on this vision with the least restrictions and a simple means by turning the optical path with a thin refracting prism or a kind of combinational mirror by which the same function as this prism is obtained and reproducing LR images when reproduced LR images are divided and distributed to any position. CONSTITUTION:Plural images different in viewpoint are divided in the vertical direction and/or the horizontal direction and are reproduced on a television screen or a display device of photographs, books or the like. A pair of LR images 3 and 4 to be three-dimensionally seen are selected from these divided reproduced images, and at least one of optical paths connecting one point on the display device and left and right eyes P and Q is turned in such direction by an optical path changing body like refracting prisms 2 and 2', total reflection bi-prism, or combinational mirrors that these two images are superposed. Thus, right and left images are easily divided and the three-dimensional image is extended in one direction at the time of getting and enjoying the image. |
