Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application') The present invention uses a one-dimensional imaging device to capture images on a starting line or a goal line provided for judging competitions in boat races, bicycle races, horse racing, track and field events, etc. has.

The present invention relates to an electronic instant determination device, which is the most advanced camera device in the world, and which instantly displays images necessary for determination on a CRT device or electronic printer to determine flying, late start, finish, etc.

(Prior Art) Hitherto, high-speed cameras have generally been used to determine the finishing order in bicycle racing and horse racing. This high-speed camera does 1 per second
Although 60 to 200 or more pieces can be placed in one shadow, the player must find the one closest to the goal line from among the many pieces.
Because the images are printed, it takes several minutes for the photos to reach the referees, which is a serious drawback in that quick decisions cannot be made. For example, even when photographing a bicycle race at 160 frames per second, the distance between each frame is approximately 10
It was difficult to make an accurate determination because the distance also increased by cm.

A slit type camera was developed to eliminate these drawbacks of high-speed cameras, and is currently widely used for determining the finishing order in bicycle races, horse races, and the like. This slit camera is 5%
Light rays are guided to the film through a narrow slit of about 3 mm, and the film is moved at a speed that corresponds to the speed of the subject. According to this slit type camera, since there is no need to select frames, photographs can be obtained within a relatively short time, but it still takes several tens of seconds to one minute to develop and print.

For example, in a boat race, a slit-type camera cannot be used to judge whether a boat is flying or running late at the start because it must be done immediately. That is,
In boat races, the system not only determines that no boats have crossed the starting line at the start, that is, at 0 seconds, but also determines that all boats have crossed the starting line one second after the start. There is a need to.

It is difficult to obtain data for making such a determination quickly after one second has elapsed from the start using a conventional slit type camera.

(Problem that the invention attempts to solve) Like this! It is important to obtain judgment materials as quickly as possible, not only when judging a single boat's flying or lagging start, but also when judging the finishing order in competitions such as bicycle racing and horse racing.

Instead of such a slit type camera, an electronic slit camera device was developed in 1977, which produced a slit image by sequentially supplying the output of a line-scanning image pickup tube to a picture tube.
It is described in Japanese Patent No. 9-30306. With such a device, the trouble of developing can be saved, so that, for example, an image of an object rushing into a goal can be displayed instantly. However, with this device, the output of the image pickup tube that scans in a line is displayed sequentially on the picture tube, so it is difficult to capture images over a relatively long period of time, such as when determining whether a boat is flying at the start of a boat race or is late. When it is necessary to display an image, it takes a long time to complete one frame (screen), making it impossible to use a normal monitor and making the device expensive. Furthermore, it is difficult to display various information that is superimposed on the image of the object and used for determination.

Electronic slit camera device as mentioned above
30306), images of objects passing through a reference line, such as a start line or a goal line, are scanned along the reference line by a camera device equipped with a line image sensor arranged to capture the image. An electronic determination device (Japanese Patent Publication No. 55-24831) has been developed that scans in a direction orthogonal to the object and displays an image of the object and the time and other information to be displayed superimposed on this image.

Even with such an electronic determination device, it is said that approximately 1.2 seconds are required for a determination image to appear on the monitor. With this type of device performance, in boat races that use a flying start method, the judge can only make a judgment on whether the start is successful after 1 or 2 seconds, and if you add an additional 1 to 2 seconds to make the judgment, the boat will not be able to start. Approximately 54m from the line (assuming the port speed is approximately 20m/sec)
0m/sec x (1,2+1.5) seconds = 54m) ahead and tee off.

In addition, the same time delay occurs when determining whether a start is unsuccessful due to a late start, which not only reduces the fun of the race by half, but also poses a problem to competition management. It has been strongly desired to realize a device that can shorten the length so that it can be ignored and display it immediately.

In addition, in races such as boat races, horse racing, and bicycle racing, the race ends in a few minutes, but the race is judged only for a few seconds when the competitors cross the start or finish line. The captured video is unnecessary information.

Therefore, in order to economically configure the determination device, it is sufficient to automatically or manually extract only the video information necessary for determination and store it in the main memory device.

Taking this as an example in the case of a boat race, it is sufficient to extract about 10 seconds of video from the start and finish for a race that lasts about 3 minutes, which means that the information can be compressed to about 1/20.

Furthermore, as a result of fierce competition among the images captured in this way, there are cases where judgments are forced to be made with close differences. As a countermeasure to this problem, it is necessary to enlarge the image on a display device such as a CRT by n times in the time axis direction to facilitate determination. Furthermore, after the loose competition is over, there may be cases where the contents of the main memory device are scrolled and the start and goal situations are displayed again on the display device. These enlarged displays, scroll displays, etc., as well as the instant display mentioned above, are functional requirements for temporal and spatial reading methods for the main memory device.

Furthermore, with the development of image display technology, various types of display devices and electronic printers that output images are becoming available, but unfortunately the signal input conditions for these devices are far from being standardized. It was necessary to realize a device with good connectivity between the determination device and the output device.

The present invention economically configures the device by extracting only the information necessary for determination, and of course displays the determination image immediately.
Various ancillary functions necessary for judgment, enlarged display of part images,
An electronic instant judgment device that facilitates the implementation of scrolling displays, repeated displays, etc., increases the degree of freedom in selecting an output device, and makes it easier to match the imaging speed that changes depending on the type of competition with the input information speed of the output device. This is what we are trying to achieve.

(Means for Solving the Problems) The present invention provides a high-sensitivity imaging device that continuously captures images of a moving body passing on a determination line such as a start or finish line using a camera device having a one-dimensional imaging device; A conversion additional circuit that A/D converts the analog video signal obtained and adds digital information such as characters, symbols, time lines, etc., and extracts the time interval necessary for judgment from the obtained digital signal automatically or manually. a temporal extraction device, a main memory device that sequentially stores digital signals that can be written and read only for signals from which only the necessary portions are extracted by temporal selection; a sub-memory device that extracts and sequentially stores the necessary sections according to the input conditions; a display device that reads and outputs according to the input conditions; an image print device that receives the output of the sub-memory device and reads out high quality; Related to a drive circuit that supplies drive signals to an imaging device, a conversion addition device, a temporal extraction device, a main memory device, a sub-memory device, a display device, an image printing device, and the drive circuit that generates synchronization control and gate signals. and a control signal generation circuit that generates a control signal by continuously capturing an image of a moving object passing on a judgment line such as a start or a goal line with a camera device having the one-dimensional image sensor. The analog video signal obtained is converted into a digital signal, digital information such as characters, symbols, time lines, etc. Only the signals that have been detected are sequentially stored in a writable/readable digital main memory device, and necessary sections are further extracted from this main memory device according to the purpose of the output device, and sequentially stored in the sub memory device. The present invention relates to an electronic instant determination device characterized in that it is configured to instantaneously determine required information by reading and outputting it in accordance with input conditions.

(1) Temporal extraction device 4: A video signal processing device handles an extremely large amount of information compared to a general information processing device, which is a factor that makes the device expensive. Electronic determination devices are no exception to this, and must have the ability to selectively capture only the information necessary for determination from continuously captured signals and discard unnecessary information as much as possible. For this purpose, the present invention provides a temporal extraction device 4.
will be established. this! ! To explain the flying start system for boats as an example, a boat race start is established when the clock device 9 indicates 0 seconds, the boat does not cross the starting line, and it is stipulated that the boat must cross the starting line one second later. . Therefore, the camera device 2 starts capturing the image on the start line when the big clock reaches about -0.2 seconds, continues until it reaches about +1.2 seconds, and this range can be used as the judgment image. Video information other than during this period is unnecessary. Therefore, in this case, by sending time signals of -0.2 seconds and +1.2 seconds from the clock device 9, it is possible to temporally extract the necessary video. Also, when it comes to goals,
Normally, the goal line is crossed separately from the top layer to the last layer, so all you have to do is predict when each boat will cross the goal line and extract the time by operating the push button 84, which takes about 10 seconds to reach the goal. Arrival status 2~
It is possible to make a determination based on 3 seconds of image information.

The temporal extraction device 4 is a type of temporal extraction device that selectively passes through only the necessary sections to be judged based on the video information continuously imaged by the camera device 2 by automatic operation by a clock device 9 or by manual operation of a push button 84. Operate as a gate circuit.

In order to perform this operation, the camera device 2 uses 14
A line scan signal of 00 Hz is applied from line 72-1, a dot readout drive signal of 1400 Hz x 1024 is applied from line 72-2,
These drive signals are controlled by a synchronization signal generated by a crystal oscillator 71 and a control signal from a control signal generation circuit 81 synchronized with a time axis signal generated by a clock device 9, respectively, and applied to the camera device 2.

In the conversion addition device 3, a line synchronization signal of 1400I (7) and a focus synchronization signal of 1400H2X1024 (pixels) x 8 (bits) are applied from the drive circuit 72 of the drive device 7 to the A/D conversion device 31, and the camera device A/D convert the analog output signal from 2 into a digital signal,
A digital signal is applied to an additional circuit 33. The additional circuit 33 receives a portion of the digital video signal from the line 73-1, and also receives information from the gate circuit 73 of the drive device 7, which is controlled in time synchronization with the information capotan circuit 82 of the control circuit 8. Various information input code signals are applied to a digital image signal generation circuit 32, converted into digital image information signals, and applied to an addition circuit 33 to add various additional information.

The extraction gate signal applied to the temporal extraction device 4 is automatically applied to the drive device 7 by the operating switch circuit 83 of the control circuit 8.
The signal is sent out through the gate circuit 74. In this way, the temporally extracted output from the additional circuit 33 is applied to the next main memory device 5.

(2) Main memory device 5; The purpose of providing the main memory device 5 in the present invention is as follows. In other words, due to its nature, determining the outcome of a competition cannot be repeated. Furthermore, when there is a doubt about the judgment result after a competition, it is necessary to reproduce the video, so the accumulation of video signals is an essential function of the judgment device.

Further, when a plurality of output devices 64 are installed, it is clearly uneconomical to install memory devices according to the purpose of each output device because information may be stored redundantly. Furthermore, in the instant determination device of the present invention, the memory device can also perform an instant display function. The main memory device 5 is provided as a common set memory device having an immediate read function in order to realize these multiple requests.

FIG. 2 shows details of the main memory device 5. In FIG. 2, 51 is a gate circuit, 52 is a memory element, and 53 is a read function circuit.

The gate circuit 51 includes a plurality of gate circuits 51-1゜51-
2. -51-n are arranged in parallel, and the signal from the temporal extractor 4 is gated by the write signal of the main memory device 5 through line 75-1 to sequentially record in the memory element 52.

As shown in FIG. 2, receiving digital video signals from the temporal extraction device 4, 51w 1 , 51w 2 . . . 51w

52-n, 53R1, 53R2...53
It has the ability to read through Rn, and the write W and read signals are 51W1.53R1, 51W2, 53R2
, 51Wn, and 53Rn (alternately). In this way, the judgment target section is accumulated densely without overlapping, and the function of reading it out immediately is realized. These controls are performed by the drive circuit 72. It is done by a signal.

(3) Functional reading/reading device 61; In the present invention, the purpose of providing the functional reading device 61 is to store images necessary for judgment in the main memory device 5 as common information in chronological order. In response to different requests, such as instantly extracting and displaying a CRT or other display device 64-1 for determining the start situation, or printing out using the image printing device 64-2 for determining the goal situation, etc. The required section must be read from a specific area in the main memory device 5 at the required time. For this purpose, a functional readout device 61 is installed between the secondary memory device 62. Examples of this function are classified and shown in Table 1.

These functional reads are performed by changing the control j11 pattern of the functional read instruction circuit 85.

The operation of the functional readout device 61 of the present invention is as follows.

Depending on the display range, display time, etc. of the output device 64 connected to the system, the functional readout device 61 may be set in advance in a planned manner, or it may not be possible to set it without looking at the competition situation. It is automatically controlled by a program built into the device 8, and the latter has a structure that allows readout operations to be performed at any time by manual operation of the instruction circuit 85. For example, to immediately output the start judgment video captured from -0.2 seconds to +1.2 seconds to the CRT device 64-1, operate the (1) area readout and (2) immediate readout functions shown in Table 1. and one-dimensional image sensor 2
2 finishes scanning one line and writing through the line 51W1 of the main memory device 5, it is immediately read out and stored in the sub memory device 62-1 in the next 53R1 cycle. In addition, when displaying the goal video on the image printing devices 64 to 2, the goal video can be printed out by reading out the video of the goal area stored in the main memory device 5 using (1) area reading in Table 1. can.

In addition to the above, the functional reading device 61 has functions such as (3) enlarged reading, (4) scroll reading, and (5) repeated reading.

(4) Sub-memory device 62 and output coupling device 63; The purpose of providing the sub-memory device 62 and output coupling device 63 is as follows.

Writing to the main memory device 5 is performed in synchronization with the scanning of the one-dimensional image sensor 22, and the frequency is shown in Table 2 <4
It is in the range of 00 to 2100 Hz.

- The scanning frequency of the force output device is 50H as shown in Table 3.
Since it is in the range of z to 84 kHz, it cannot be directly coupled.

A sub-memory device 62 is provided in order to utilize the information storage function of a memory and combine both functions without impairing their functions. The output coupling device 63 is a control device that couples this sub-memory device to the output device 64 and includes a D/A converter if necessary.

(5) The operations of the sub memory device 62 and the output coupling device 63 are as follows. Scanning frequency 1 of one-dimensional 1-most image element 22
400Hz, operating frequency of display device 64-1 84kHz
z (vertical scan), frame frequency 60Hz (horizontal scan)
An instant display method for sequentially displaying images at the same time as imaging will be described using the case as an example.

The video signal taken in by the one-dimensional image element 22 at 1400 Hz passes through the conversion/additional device 3 and the temporal extraction device 4, and is written into the main memory device 5. The signal relationship when reading this and immediately displaying it on the display device 64-1 is the display device 64-1.
1400 images/frame of 4-1 (84kHz
/60Hz), while 23 signals/frame (14001
-12/60Hz), the correction to the new image is made,
It will be displayed immediately.

The output coupling device 63 reads from the sub-memory device 62-1 using the control signal supplied from the drive device 7 and outputs it to the output device 64-1.
Provides the ability to write to.

(Operation) Next, the flow of the operation according to the present invention will be explained with reference to the overall configuration diagram of FIG. 1. The image of the subject 1 is captured by the lens 2 of the camera device 2.
1 and connects the image onto the surface of the one-dimensional image sensor 22 placed so as to coincide with the determination line 12.

In this state, when a scanning signal is supplied from the drive circuit 72 to the image sensor, the first image element scans on the determination line 12, and generates a video fragment determined by the period and the speed of the moving body passing through it as an analog video signal. do.

This signal is led to the conversion/addition device 3, converted into a digital signal by the A/D converter 31, and mixed with digital information in the addition circuit 33 to form a digital video signal.

This digital information is usually recorded information such as race location, date, and race number that is written along with the output image, and is set in advance by the information input pushbutton circuit 82 and generated as a digital signal by the digital information generation circuit 32.

The digital video signal obtained in this way is time-extracted automatically by the time extraction device 4 using a start signal supplied from the clock device 9, or manually by the operator's manual operation of the push button 84, and the time is extracted by the time extraction device 4. The data are sequentially stored in the memory device 5.

Now, the start video is immediately displayed on the display device 64-1,
A case where the goal video is simultaneously output to the image printing device 642 will be described. As explained above, by the area readout and immediate readout functions of the functional readout instruction circuit 85 and the functional readout device 61, the video signal of the start section is stored in the main memory device 5 and the sub memory device 62- for each scan of the image sensor. As a result, a new image is added to the image on the display device 64-1 for each frame, and the image on the display device 64-1 is transferred to and stored in L, as if unfolding a picture scroll.
-1, the start video is immediately displayed.

On the other hand, for the image printing device 64-2, the functional readout instruction circuit 85 and the functional readout device 61 read out the area of the goal section, and the functional readout device 61-2
extracts the goal section from the main memory device 5, sequentially re-stores it in the sub-memory device 62-2, and reads it out under the control of the output coupling device 63-2, and prints out the goal video on the image printing device 64-2. do.
