DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for electronically determining the order of arrival and the goal time used in athletics, boating, and the like.

[0002]

2. Description of the Related Art Conventionally, in athletics, boating, and the like in which one-thousandth of a second is competing, a device for electronically determining the order of arrival and the goal time has been used. In particular, it has been known that a determination apparatus using a slit camera that scans in a line shape to project a slit image, and superimposes vertical lines to determine a landing order can perform strict determination.

[0003]

However, if a plurality of competitors enter the goal line almost simultaneously at the same time due to a melee competition, the athlete on the near side will be displayed on the captured video by the image of the competitor on the near side. When a part of the image is hidden, and it is an important part in determining the order of arrival, there has been a problem that strict determination cannot be performed.

For this reason, conventionally, cameras of respective devices are installed at both ends on the extension of the goal line using two arrival order judging devices, and a video taken from the near side and a video taken from the back side are taken. The image and the image are projected on different devices, and the judgment is made while comparing the respective images.

[0005] However, with such a determination method, an expensive arrival order determination device must be separately purchased and used, and the purchase cost increases. In addition, when running the competition, two finalists are required, and the cost of running the competition also increases. Further, there is a problem that an extra installation space is required.

[0006] Further, since the front-side photographed image and the back-side photographed image are displayed on separate image display devices, when judging the order of arrival, two judges who are in charge of the respective order-of-arrival judging devices are two. Judgment must be made while moving between apparatuses and comparing images, and it takes time, and it is difficult to shorten the judgment time in the arrival order judgment which requires quick reportability.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a conventional problem and to realize an arrival order determining apparatus capable of performing quick and strict determination with one arrival order determining apparatus.

[0008]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a arrival order judging device for electronically judging an arrival order and a goal time, wherein a video signal from two cameras having a line image sensor is provided. And a video signal storage means for sequentially storing and storing the video signals sequentially, and selecting one of the video signals from the two cameras stored by the video signal storage means to read out and display the video signal at any time. One projection means and two stored by the video signal storage means.
A part or all of any one of the video signals from the cameras, and a part and all of the other, selectively combined and read out at any time, and combined projection means for projecting on one screen,
A display selecting means for selecting one of the display by the alternative projecting means and the display by the composite projecting means.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of the present invention.
Is a camera A for capturing a subject and the other camera B is for capturing a subject. The slit-shaped pixel signals sequentially supplied from the two cameras are converted from analog video signals into digital video signals by A / D converters 31 and 32 provided in the video signal conversion device 3, respectively. The data is sequentially stored and stored in the semiconductor memory device 33.

There are various storage and storage methods. For example, the first half of the memory in the semiconductor memory device 33 is used for storing the video signal of one camera, and the second half is used for storing the video signal of the other camera. You may memorize it. Also, video signals from both cameras may be stored alternately.

The video signal data stored and stored in the semiconductor memory device 33 can be read at any time, and any data can be read. Reference numeral 4 denotes a control device that controls display of an image displayed on the slit image projecting device 5, and sends the image signal data in the semiconductor memory device 33 to the display memory device 34. At that time, the control device 4 selects one of the video signals of the two cameras or selectively synthesizes a part or all of one of the two cameras and a part or all of the other, and displays them on one screen. Selective control of video signal. The video signal selectively controlled by the semiconductor memory device 33 and sent to the display memory device 34 is output from the D / A converter 3.
At 5, the digital video signal is converted into an analog signal, and is projected by the slit image projection device 5. Reference numeral 36 denotes a superimposed video generation device for superimposing character information and line drawing information on the slit image projection device 5.

FIG. 2 is a schematic diagram showing a use state of one embodiment of the present invention, and shows a vicinity of a goal line of a track in an athletics stadium where an athletics is performed. Two cameras 1 and 2 are installed at both left and right ends on the extension of the goal line, and a subject jumping into the goal line 6 is photographed from the left and right, and is judged by the arrival order judgment device 3.

FIGS. 3 and 4 show display examples of images projected on the slit image projection device 5. FIG. FIG. 3 shows a display example of a video image captured by the camera A1, and FIG. 4 shows a display example of a video image captured by the camera B2. The switching of the display examples shown in FIGS. 3 and 4 is performed by the control device 4, and when judging a small difference, the two images may be switched and compared. In order to facilitate comparison and comparison, a course number 7 was generated from the superimposed image generation device and superimposed and projected on each screen.

FIG. 5 and FIG. 6 show an example in which the image picked up by the camera A1 and the image picked up by the camera B2 are combined and displayed vertically. FIG. 5 shows an example in which the image of the camera A1 is displayed in the upper part and the image of the camera B2 is displayed in the lower part. FIG.
Is an example in which the image of FIG.

If the display as shown in the examples of FIGS. 5 and 6 is performed, the images picked up by both cameras can be confirmed on one screen at a time, so that the judgment can be made strictly and quickly. FIG. 7 and FIG. 8 show examples in which a video image captured by the camera A1 and a video image captured by the camera B2 are displayed side by side.

FIG. 7 shows an example in which the image of camera A1 is displayed on the left and an image of camera B2 is displayed on the right. FIG. 8 shows an example in which the image of camera B2 is displayed on the left and the image of camera A1 is displayed on the right. As shown in the display examples of FIGS. 3 to 8, the slit images from the left and right near the goal can be compared and compared with the same size to confirm the order of arrival, but as shown in FIGS. It is also possible to combine and project a part of the other image on the image. If there are many competitors and the contrast is troublesome, if only the video of the course to be contrasted is displayed, the arrival order can be determined more quickly.

[0017]

As described above, according to the present invention, a video signal from two cameras having a line image sensor is stored in a video signal storage in a video sequence determination apparatus for electronically determining a video landing order and a goal time. The means sequentially accumulates, and the alternative projection means selects any one of the video signals, reads out the image signal as needed, and projects the image signal. Also,
A part or all of one of the video signals from the two cameras stored by the video signal storage means,
And a combined projection means for selectively combining and partially combining the other part and reading out the image at any time and projecting the combined information on one screen. By comparing and contrasting the images, quick and strict arrival order determination can be performed.
