The viewer sees it from the side and feels strange. In addition, since the camera group 21 exists inside the field 2, the camera group is an obstacle for the audience in the actual shooting field.

[0008]

SUMMARY OF THE INVENTION Normally, the direction of an athletic object viewed at a grandstand is made to coincide with a video viewed at a reproduction hall. Or, remove the cameras in the actual shooting field from the field.

[0009]

In an actual shooting field, an athletic object orbiting on a track is photographed from outside the track and transmitted to reproduce an image on a screen surrounding a viewing room.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an actual video field, which is a part of a video system, showing one embodiment of the present invention. The live-action field 1, which is an athletic object, has a field 2, a track 3, and a spectator seat 4 around the center. The track 3 has a goal 5, and the audience usually concentrates on the seat outside the goal 5 so that the vicinity of the goal that determines the outcome of the game can be clearly seen.

Reference numeral 6 denotes a group of cameras, which are arranged on the outer circumference of the track or in a pseudo-circumference at substantially the same angular distribution with respect to the center of the field. Each camera group has a photographing area in front of the track, and as the athletic object goes around the track, it is sequentially photographed by the next camera, so that the entire camera group can photograph all tracks.

FIG. 2 shows a video reproduction site 7 which is a part of the video system of the present invention. In the figure, reference numeral 8 denotes a display group which is a set of independent displays, and the lowermost end thereof is indicated by 9. The reproduction area 7 has a ceiling 10 and a floor 1
It is surrounded by one. Reference numeral 12 denotes an entrance to the reproduction site. Each configuration of the display comprises a screen 13 and an exemplary projection portion 14 for projecting onto the screen. It is standard for the viewer 15 to stand and view, and the lowermost end 9 of the display is set approximately 1.5 to 3 m higher than the entrance 12 and the head of the viewer 15.
The display with the height of the lowermost end set in this way is connected in the horizontal direction without a gap, covers 360 degrees in a horizontal plane, and goes around the viewing room.

FIG. 3 is a block diagram showing the entire configuration of the present invention. The camera groups 6 in the actual shooting field correspond one-to-one with the display groups 8 in the playback field via the transmission path 16, so that all parts of the track can be seen continuously in the playback field.
