Abstract

(57) [Summary] [Purpose] To allow baseball broadcasts to be served to television viewers by allowing them to shoot from positions that could not be captured with conventional camera positions. [Structure] A CCD camera 3 is incorporated in a part of a helmet 1 worn by a baseball ball referee with its lens surface 3a facing forward, and the output side of this CCD camera 3 is connected to this C
It was connected to a transmitter 7 which amplifies the output signal of the CD camera 3, modulates it at a high frequency, and transmits it as an electromagnetic wave. As a result, an image similar to that seen by the ball referee can be obtained, which could not be obtained through the conventional back net.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television camera device equipped with a ball trial, which is applied when a game played in a baseball field is relayed on a television or video recorded.

[0002]

2. Description of the Related Art A baseball game, particularly a professional baseball game, is photographed by a television camera and broadcast from a broadcasting station. The shooting for this purpose uses multiple TV cameras, and is arranged to follow the ball mainly around the whereabouts of the ball, but the most interesting scene for the TV viewer is that one pitcher throws one ball. The result. That is, whether the ball that was thrown was a strike or a ball, and if it was a strike, whether it was a straight ball, a curve, or a fork ball.

Because of the great interest in pitching by pitchers in this way, even in the current broadcast television shooting, some measures have been taken to understand the flow and speed of the ball, and it is necessary to capture the moment when the catcher enters the mitt. Efforts are also being made. Of these, when shooting from the back of the catcher, that is, when shooting a ball leaving the pitcher's hand toward the catcher, it is taken by a television camera installed behind the back net.

[0004]

As described above, when shooting with a TV camera installed behind the backnet, the images of the ball referee and the back of the catcher get in the way, and the ball near the strike zone that you want to see the most There was a problem that could not be seen. Therefore, recently, with the development of super telephoto lenses, images from the back screen have come to be widely used. With the development of this camera position, professional baseball TV broadcasting can deliver more details than the stadium to the tea room.

The image from this position can clearly capture a series of dramas starting from the exchange of signatures between batteries and the battling with the batter, the change of the thrown ball, and the corresponding swing of the batter. However, the image from this position tends to lack the power in the movement of the ball because the pitcher follows the ball thrown from behind. On the other hand, the image shot by the camera installed on the back of the back net is very powerful because the ball moves toward the camera.

As described above, since the images taken by the camera installed on the back of the back net are very powerful, it is desirable to use a large amount of them during the broadcast time. I can't see the essential parts or subtle parts of the video.

The present invention has been made in view of this point, and the image in the direction conventionally captured by a camera installed on the back of the backnet is further enlarged, and the ball trial is not disturbed by the base referee or the catcher. It aims to provide a photographing device capable of obtaining an image with a field of view almost the same as that seen by.

[0008]

According to the present invention, as a means for solving the above problems, a CCD camera is provided on a part of a helmet or a mask worn by a baseball ball referee so that the lens surface thereof faces forward. It is constructed such that the output side of the CCD camera is connected to a transmitter that amplifies the output signal of the CCD camera, modulates it at a high frequency, and transmits it as an electromagnetic wave.

[0009]

With this configuration, the CCD camera captures a field of view that is almost the same as that of the baseman's eyes, so that the pitcher looks at the catcher's mitt and the ball thrown powerfully becomes a white thick line for the viewer. It will be approaching, and it will be displayed on the television screen as if it changes drastically before the batter and is sharply hit with a bat. So many baseball players who saw this would once again be reminded of the excitement they experienced in the batter's box.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIG. 1, reference numeral 1 is a helmet worn by the ball referee. The helmet 1 is placed inside a mask (not shown) to be worn on the face and worn on the head. The upper part of the helmet 1 is extended slightly above the normal one, and a hole 2 is provided in the extended portion 1a. Then, a cylindrical CCD camera 3 having a diameter of about 2 cm is inserted into the hole 2 with the lens surface 3a facing forward, and is fixed by the following structure.

As shown in FIG. 2, the CCD camera 3 has
Two to four L-shaped brackets 4 are provided on the outer peripheral portion thereof, and the CCD camera 3 is detachably attached to the helmet 1 by screws 5 which are inserted through the brackets 4. An output code 6 of the CCD camera 3 is connected to a transmitter, which will be described later, which amplifies the output signal of the CCD camera 3, modulates it at a high frequency, and transmits it as an electromagnetic wave.

FIG. 3 schematically shows a transmitter 7 which amplifies an output signal of the CCD camera 3, modulates it at a high frequency, and transmits it as an electromagnetic wave. The transmitter 7 has
An amplifier 8 for amplifying an output signal of the CCD camera 3, a modulation circuit 9, an oscillator 10, a high frequency amplifier 11 and a battery 12 as a power source are housed. The output side of the high frequency amplifier 11 is connected to the antenna 13.

The television camera device thus constructed has the helmet 1 when the ball referee judges a baseball game.
The CCD camera 3 is inserted from the rear into the hole 2 provided in the extended portion 1a of the
Firmly attach to helmet 1. Then, a mask (not shown) is attached to the face. The output cord 6 of the CCD camera 3 is connected to the input part of the transmitter 7. The transmitter 7 is attached to the waist of the ball referee or the like. If necessary, a small microphone or the like is attached to the front of the mask, and its output signal is transmitted from the transmitter 7 together with the image.

FIG. 4 is an image captured by the CCD camera 3 in this manner. As you can see from this video, the pitcher
Fourteen forms can be seen in a position just above the head 16 of the catcher 15. The image of this position is something that could not be obtained by conventional shooting over the back net,
From the form of the pitcher 14, the viewer can observe the flow of the ball, the change in the trajectory of the ball, and the like in the same position as the ball trial. From this position, the batter and the flow of the ball
The 17 movements can also be seen in detail. Although illustration is omitted, it is possible to observe the stolen base and other movements of the catcher 15 and a runner (not shown) from the same position as the ball trial.

In the embodiment described above, an example in which the CCD camera is attached to the helmet has been described, but the present invention is not limited to this. Instead of the helmet, a part of the mask may be extended upward and a CCD camera may be attached to the extended portion. Further, when it is attached to a helmet, it may not be inserted into the hole as shown in the embodiment but may be detachable by other means such as providing a holding metal fitting.

[0016]

Since the present invention is a television camera device configured as described above, it is possible to obtain an image that could not be obtained in the past, so that enthusiasts who enjoy baseball on television can enjoy it. You will be able to get enough satisfaction. Since a CCD camera that has recently been made smaller and lighter is used, even if it is attached to a helmet or the like, it does not impose any burden on the ball referee, and when considering its video value, its contribution to the broadcasting industry is There is something remarkable.
