PURPOSE: To easily cope with display systems different in display circumstances to relax restrictions on photographing and display by storing the video of a wide-range three-dimensional scene and obtaining two-dimensional videos to be displayed in accordance with display circumstances by a calculating means.

CONSTITUTION: A video 3 of a wide-range three-dimensional scene including two-dimensional videos to be displayed on display screens 1a, 1b, and 1c of a display device 20 is inputted by a three-dimensional scene input device 12. The scene input device 12 photographs with a camera to which a lens capable of photographing a wide range is set. The video of the tree-dimensional scene from the scene input device 12 is stored in a storage device 16 through a processor 14. The processor 14 typically includes a microcomputer and the other data processors and converts the video 3 of the three-dimensional scene read out of the storage device 16 to two-dimensional videos to be displayed on display screens 1a, 1b, and 1c. Display circumstance information such as directions of sight and angles of visual fields for display screens 1a, 1b, and 1c from an observer is inputted from a display circumstance input device 18.
