Description

[Detailed description of the invention] Judgment of finish in publicly managed competitions such as horse racing, bicycle races, and boat races, or track events is generally performed by interpreting a judgment photograph taken with a slit camera.

This determination requires that the determination be accurate and that the determination result be known as quickly as possible.

On the other hand, interpreting the evaluation photographs on the developed small film is a very difficult task even for experienced judges.

Therefore, by using a television camera to enlarge and project the required image of the judgment film on the cathode ray tube of the judgment television monitor, and by reading the enlarged image on the screen, accurate judgments can be made easily and quickly. A device was devised and published in Utility Model Application No. 111096/1983
No. 9) was filed.

However, if the race becomes a close contest and multiple competitors cross the finish line at almost the same time, multiple targets may be judged between the time scales, such as the 1-square shape that is usually printed on the judging photo. may exist.

In such cases, determination is often extremely difficult.

This invention superimposes a plurality of equally spaced scale lines on the judgment screen of the judgment television monitor, in addition to the existing time scale, and makes it possible to adjust the positions of the scale lines and the intervals between the plurality of scale lines. This makes it easy and accurate to judge minute differences in rankings on the screen, and also enables direct numerical reading of the image, making it effective for judging differences in position such as 3/4 horse length or 2.18 car length. It pertains to equipment that can be used for

The scale line superimposition device of this invention is a device inserted between a television camera and a television monitor that converts a judgment film into a television image, and is a device that is inserted between a television camera and a television monitor, and is a device that converts a judgment film into a television image. A device that generates a scale is combined with a position adjustment device that moves the position of the generated scale line within the screen in a direction perpendicular to the scale line, and an interval adjustment device that proportionally changes the distance between the scale lines. The apparatus is characterized in that it comprises a mixer that superimposes an image of the adjustable scale line of the scale line generator and an image of the judgment photograph taken by the television camera.

In principle, the device of the present invention is manufactured as an independent device with the above configuration and used by being inserted and connected between a television camera and a television monitor, but in some cases, some of its components or The same effect can be achieved even if all of them are attached and incorporated in a part of the imaging device of the television camera for determination that takes the photograph for determination or the image projection device of the television monitor for determination.

On the screen of the television monitor into which this device is inserted, scale lines appear superimposed on the judgment screen.

By adjusting the position of the scale line so that it coincides with the tip of one of the plurality of athlete images that require detailed judgment on the screen, the context with other images can be determined very easily.

In addition, by adjusting the distance between the scale lines so that it is a predetermined fraction of the size of the athlete in the judgment image, for example, the length of the bicycle or fat body, it is possible to accurately and easily judge the clothes worn by the athletes. It's something you get.

These effects will be explained in more detail in the description of specific examples below.

Figure 1 shows an example of the use of the device of the present invention in principle.
A photo judging device, generally designated by the reference numeral 1, takes a photo 12 for judging (generally, a negative film is used that has been developed from a judgment photo taken with a slit camera of the finish line when the competitors arrive) and displays it on a television. The scale line superimposition device 2 of the present invention is connected between a television camera 11 that captures an image and a television monitor 13 that displays the image of the television camera 11.

FIG. 2 shows an example of a scale line superimposition device assembled as an independent unit device, which is entirely installed in a suitable case 20 and has an input terminal 21 connected to the television camera 11 at one end. , has an output terminal 22 connected to the television monitor 13 at the other end.

23 is a mixer inserted and connected between them, and TV camera 1
The determination image No. 1 and a scale line image to be described below are synthesized and superimposed.

24 is a scale line generation device provided in the scale line superimposition device, which generates a plurality of equally spaced lines (
An image of thin scale lines 3 (in practice, it is preferable to represent them as white lines on a dark surface) is generated.

The scale line generator 24 includes a position adjustment device 25 that moves the position of the generated scale line on the screen in a direction perpendicular to the scale line (left and right) as shown in screen 4L or 4R in FIG. 3, and a plurality of scale marks. It is combined with a spacing adjustment device 26 that reduces or enlarges the spacing between lines in equal proportion as shown in screen 4N or 4W in FIG.

The adjustable scale line image generated by the scale line generator 24 is input to the mixer 23 together with the image of the television camera 11, and is synthesized by the mixer to produce an image with the scale lines superimposed on the image for judgment. The image is displayed from the output terminal 22 on the television monitor 13 as described above.

Reference numerals 250 and 260 in FIG. 2 illustrate knobs for position adjustment and interval adjustment, respectively.

Figure 4 shows an example of a screen enlarged and projected on the TV monitor 13 of a photograph used to judge the finishing order of a bicycle race. The time scale 6 is imprinted, but many bicycles 5 that participated in the competition entered the finish line as a group, and the tips of the leading cars gathered in the middle of the two time scales 6a*6b. In such cases, it is difficult to determine the order of finish.

Figure 4 shows that the line spacing of the multiple scale lines of the present invention superimposed on the above screen is adjusted to 174, which corresponds to one car length of the car on the screen, and one of them 3a is the leading group of 3 lines arranged vertically. This screen shows the position of the wheels 5a, 5b, and 5c adjusted to match the tip of the center wheel 5b.

This adjustment is performed by superimposing a standard scale line having a plurality of scale lines on the judgment photograph and displaying it on the television monitor 13, and then sequentially or alternately operating the position adjustment device 25 and the interval adjustment device 26. carried out by

By observing the three cars using the rightmost scale line 3a as a reference, it is clearly revealed that the order of arrival is 5ct5bt5a, although there is a slight difference.

Also, the difference between 4th place 5d and 1st place 5c is at scale line 3a,
From 3b, it can be easily determined that he is almost a master of II.

Furthermore, if the interval between the scale lines is reduced to, for example, 175 (1/50th of a second) on the time scale 6, then the car 5a, 5 by
It also becomes easy to decipher the difference in time between 5 and c.

In addition, as shown in Figure 4, the judgment photo is usually taken with the athlete's direction of progress facing left and right, so a scale line generator that generates vertical scale lines is used. If you want to print the images vertically, you can use a device that creates horizontal scale lines so that you can adjust the position and spacing as before.

The scale line generator, the position and interval adjustment, and the mixer for synthesizing the screens all utilize known techniques, so detailed explanations will be omitted.

According to the above-described scale line superimposition device for the judgment screen of this invention, photo judgment can be performed extremely quickly and accurately, and it is extremely easy to judge the difference in position due to vehicle body etc. or to decipher the difference in position due to time. There is an effect that can be done.

It goes without saying that this device can be used not only for public events such as bicycle races, horse races, and boat races, but also for photo judgment of track events at general sports stadiums.
