Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for photographing races such as horse racing, bicycle racing, and track and field events using a television camera or the like.

[Conventional technology]

In the conventional method of photographing races such as horse racing, bicycle racing, and track and field events using TV cameras, one or more cameras are placed at a fixed location, and the camera is rotated to follow the racers while filming. [Problem to be Solved by the Invention] In the conventional photographing method described above, since the position of the camera is fixed, the photograph is mostly taken from a diagonal direction with respect to the running direction of the racer. Sometimes it is difficult to tell the rankings of the racers while running, especially when the racers run a certain distance around the course, such as in horse racing.

SUMMARY OF THE INVENTION An object of the present invention is to provide a photographing method capable of accurately photographing the running situation including the entire ranking of a race run or the ranking of a particularly important part of the race.

[Means to solve the problem]

In order to achieve the above object, in the photographing method of the present invention, two approximately semicircular courses facing each other.

In the method for photographing a race in a substantially oval course consisting of two substantially parallel straight lines connecting both ends,
A camera that is engaged with a track at an arbitrary height on a straight line connecting approximately the center positions of each of the two semicircles, whose photographing direction is approximately perpendicular to the running direction of the racer on the course, and facing toward the course. However, when the racer is running on a straight section of the course, the racer runs on the track at approximately the same speed as the racer, so that the racer is always photographed;
When the racer is running inside the half of the course, a camera located approximately at the center of the half rotates at approximately the same angular velocity as the racer.

Another shooting method is to engage with a track that is located outside or inside a nine-arc course and is approximately concentric with the arc-shaped course, and the shooting direction is approximately perpendicular to the running direction of the racer on the course. , and a camera facing toward the course travels on the track at approximately the same angular velocity as the racer so as to constantly photograph the racer on the varnish.

[Effect]

If the camera running on the orbit configured as above constantly photographs the racer while traveling at the same speed as the racer, or rotates or travels at the same angular velocity as the racer, the screen shot by the camera will always capture the racer as it travels. Since the screen continues to be viewed from the direction perpendicular to the direction, it is possible to accurately photograph the running situation, including the racer's running order.

〔Example〕

To explain the embodiment with reference to the drawings, as shown in FIGS. 1 and 2, an elliptical course 1 consisting of two opposing semicircles r and two parallel straight lines S connecting both ends of the semicircles r is shown. , the same height M2 from the center point of the two semicircles r,
A television camera 6 is mounted on a traveling vehicle 5 running on a track 3, that is, a rail 4, so as to be rotatable vertically and horizontally. The television camera 6 is substantially perpendicular to the running direction of the racer 7 and is facing toward the racer 7 which is facing downward diagonally.

Immediately before the race starts, that is, when the racers 7 are lined up at the starting line 8, the television camera 6 is located vertically above the extension line of the starting line 8. Therefore, at this time, the television screen is 9wi as shown in FIG. The starting line 8 is shown on the vertical line in the center of the screen. The trapezoid ABCD indicates the shooting range of the television camera 6.

When the race starts and the racer 7 starts running in the direction of the arrow, the running car 5 equipped with the television camera 6 runs on the rail 4 at almost the same speed as the racer 7, and the racer 7 is always reflected on the screen 9. When racer 7 enters the semi-circle, the TV camera 6 is placed above the center point of the semicircle at a position w3 of racer 7.
It starts rotating at the same angular velocity as 1. Once you reach the straight section, you will start running again.

It is desirable that all operations such as driving the vehicle 5, operating the television camera, and transmitting and receiving video signals be performed wirelessly.

At the moment when the racer starts or when entering an arcuate section from a straight section, extreme acceleration and deceleration are required for the running of the traveling vehicle 5 and the rotational motion of the television camera 6, which may cause practical problems. . As a countermeasure to this problem, the following methods can be considered.

As shown in FIG. 4, the first method is to set a TV camera 6a on a vehicle 5a running on an oval rail 4a located inside the course 1 and at a certain distance from the course 1. When photographing, the traveling vehicle 5a does not need to stop all the time. Furthermore, if the semicircular portion of the rail 4a is shaped as shown by a dotted line instead of a circular arc, smoother acceleration and deceleration can be achieved.

Furthermore, as shown in FIG. 5, a rail 4b may be provided on the outside of the course 1 in the same way, and in this case as well, if the shape of the rail 4b is as shown by the dotted line, smooth acceleration and deceleration can be achieved.

As a second method, before the start, the traveling vehicle 5 increases its speed while running from a position 1!9 in front of the vertically upper position of the extension line of the starting line 8 in FIG.
At the moment of the start, the running vehicle 5 is positioned approximately vertically above the extension of the starting line 8 and is set to have approximately the same speed as the racer 7. When entering an arcuate section from a straight section, the camera must be rotated while gradually decelerating the linear motion.
Make the racer always appear in the center of the screen.

A more ideal method would be to separately install a rotation-only camera on an axis perpendicular to the center point of the semicircle, and when the linear motion camera reaches 2.3, the rotation-only camera that was previously in rotation motion At this time, the rail 4 must be extended so that the linear motion camera can stop after passing 2.3 points. Also, 13 is the goal.

Unlike some racetracks, where the course is shaped like an oval, consisting of two simple semicircles and two parallel straight lines connecting the two ends,
As shown in the key diagram, there is a slightly deformed oval shape, but in this case as well, if the center of the arc is set at 2 or 3 and this is the center of rotation of the TV camera, there will be no practical problems. Compared to conventional photography taken from a fixed position, there is a significant difference in understanding the driving situation.

Furthermore, in races such as horse racing, particular importance is placed on the ranking from the final arc portion 12 to the straight course to the finish line.

On the other hand, depending on the racecourse, a large screen TV 10 is installed in front of the spectator seats 11 and inside the course 1, as shown in the diagram.
There are times when images on a television are shown to customers, but in such cases, the photographing according to the present invention is obstructed by the large double-sided television 10, making it impossible to photograph an important spot just before the goal 13.

Furthermore, in the image captured on the large screen television 10 by the fixed point television camera 14 installed on the spectator seat side, and in the general broadcast image, the actual running direction of the racer and the running direction on the screen are the same, so there is no sense of discomfort, but the present invention Except when the racer is running on the course in front of you, the direction in which the racer is actually running is the same as the direction on the screen, and when the racer is running on the course in front of you, the direction is reversed, which feels strange. is strong.

As a means of solving these three problems, as shown in FIG. 7, excellent results can be obtained by combining several photographing methods.

First, from the start of the race until the time when the race goes around the first arc section 15 and enters the opposite straight section 16, the fixed point television camera 14 is used as in the past.

After entering the straight section in front of the other side, the TV camera 6 on the vehicle 5 running on the rail 4 of the present invention is switched to take an image.

At the next arc section 17, the television camera 6 rotating at 2 takes pictures, and from the last most important scene on, an arc-shaped rail 4 installed concentrically outside the last arc section 12 of the course is used. Television camera 6 on top of traveling vehicle-5b layered on
b photographs while traveling at the same angular velocity as racer 7.

The 4th place rail is set parallel to the course from when the course becomes straight to the finish line, and the running car 5b suspended from it moves in a straight line, and the television camera 6b photographs the racer 7. At this time, it is desirable that the rail 46 be provided on the roof of the bleachers 11, or on the rear surface of the tip when the bleachers 11 are on the second floor or 3N.

Also, when switching from the TV camera 6 to the TV camera 6b, the running direction of the racer 7 is reversed, so in order to eliminate any sense of discomfort, there is a fade-in and fade-out in which the first screen gradually disappears while the next two sides gradually appear. When taking pictures, it is desirable to use the TV camera 6b to first take a wide-angle shot to capture the state of running on the last circular arc section 12, and then zoom in to telephoto to reduce the sense of discomfort. 6b can also be shared.

In the above embodiment, the track was a rail installed at a position higher than the ground, but instead, the track may be set at the same height as the ground and the height of the traveling vehicle may be increased, or the track may be set at the same height as the ground. Hanging vehicles may also be used in suspended stadiums with tracks mounted on the ceiling.

〔Effect of the invention〕

Since the present invention is configured as described above, it is possible to easily and accurately view the rankings of all runs from the start of the race to the finish line, and even when viewing from the spectator seats at the race track, the racers themselves can be seen. It is possible to grasp the race rankings more accurately when viewed on a large-screen TV using the photography of the present invention, which contributes to improving the enjoyment of watching races on broadcast or at the race track, and to preserving accurate records. It is something.
