Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image determination device used for determining the order of arrival in horse racing, bicycle races, boat racing, auto racing, etc., and for determining the shape and characters of an object moving at high speed.

[0002]

2. Description of the Related Art For example, a slit type camera has been widely used for the arrival order determination of a horse race, a bicycle race, a boat race, an auto race, etc. In this method, a certain amount of time is required for developing a film. Therefore, there is a problem that the arrival order cannot be determined quickly. Therefore, the applicant of the present invention has proposed an image determination device capable of performing determination work quickly and easily by converting an image into an electric signal and processing it with digital image data (for example, JP-A-63-63). 31
6986, JP-A-63-316987, JP-A-1-174174, JP-B-4-50792, and JP-B-7-79470-2).

In the above-mentioned proposed image judging apparatus, a moving object passing on the goal line is vertically imaged by a line sensor camera having a plurality of one-dimensionally arranged photosensitive elements. Then, first, the analog electric signal output from this line sensor camera is sequentially converted into digital image data, and the image data for a predetermined time is written in the continuous video memory for a plurality of screens, and then the required display range is output from the video memory. The image data corresponding to is read out, converted into an analog video signal, and displayed on a TV monitor. In this case, the line sensor scan speed (accumulation time) is set to 1/1000 seconds in order to make it possible to determine the order of arrival in various competitions such as horse racing and boat racing, and one second is displayed on one screen of the TV monitor in real time when recording is started. While displaying an image, time-lapse image data for 16 seconds, that is, image data for 16 screens, is stored in the memory every 1/1000 second. The umpire determines and confirms the arrival order and arrival time while scrolling the stored time image back and forth with the scroll lever of the operation unit.

[0004]

By the way, in order to determine the order of arrival of horse races, bicycle races, boat races, auto racing, etc., not only the order of arrival is determined, but also the elapsed time from the start of the moving object to the goal is determined. It is necessary to confirm and record, and in the image determination device, elapsed time data is superimposed on pixel data and stored in a video memory (see, for example, Japanese Patent Publication No. 7-79472). That is, the time data generating circuit generates elapsed time data every 1/10 second unit, displays the time display reference line and the elapsed time from the start, and further divides it into 10 equal parts. It is written in the video memory together with the object image so that the time display line of 100 seconds is displayed.

Therefore, when judging the order of arrival and recording the elapsed time of each rank, the umpire reads the time display reference line and the time display line with the still image displayed on the television monitor and inputs the elapsed time. It will be. When determining the order of arrival and inputting the elapsed time, the operation of reading and inputting the elapsed time for each rank is repeated, which makes the referee's work complicated and burdensome. It also causes input mistakes.

Further, in the case of reproducing the image data recorded by the external device in the video judging device, it is possible to set the judging device to the state recorded by the external device, for example, clockwise or counterclockwise and then reproduce. It was necessary and the operation was complicated.

In the measurement mode, a single line (scale line) and a time display frame are displayed on the monitor, and the time of the single line position is displayed in the time display frame. The time display frame and the single line are movable. In the measurement display mode, the displayed horse number, boat number, and time are displayed. The time display frame when measurement is on is displayed at a fixed position.

For example, in the horse racing mode, when the measurement on / off button is pressed, the operation of the measurement mode is turned on, the LED of the measurement on / off button is turned on and the LED of the single line / double line button is turned off, and the monitor is displayed. Display single line and time display frame. At this time, the time of the single line position is displayed in the time display frame. Then, the time is measured according to the tip of the nose of the horse, which is measured by operating the position knob. When the measurement on / off button is pressed again, the operation of measurement mode is turned off,
The single line of the monitor and the time display frame are erased, and the LED of the measurement on / off button is turned off.

When the measurement setting button is pressed while the LED of the measurement on / off button is lit, the measurement display mode is turned on, the LED of the setting button is lit to display the single line and the time display frame on the monitor, and Item display, horse number frame blinking. In this state, the operator also uses the position knob to align the single line with the tip of the nose of the leading horse, and performs the image scrolling operation so that the leading horse enters the measurement area on the right side of the screen. When the horse number is entered with the 16 key, the input number is displayed in the horse number frame of the item display, and the horse number is registered when the setting button is pressed. At this time, the time frame blinks, and when the time display frame is checked and the setting button is pressed, the time at the single line position is displayed in the time frame and registered. For the next landing, the operator performs image scrolling operation to move to the measurement area and sequentially inputs and registers according to the operation of aligning the nose of a single line. When the setting button is pressed, the display is terminated, all input data is stored, and
All the display items on the monitor are erased to enter the measurement mode, and the LED of the setting button is turned off. When the confirmation button is pressed at the time when all the input is completed, the input registration data is printed out and all the input data are stored, and the measurement mode is set.

The data that can be registered and stored in the measurement setting can be stored for 12 races in the frame of 20 horses per race in the case of horse racing mode. In the main running mode of the boat race, the start data and goal data of 6 boats per race can be stored. You can memorize 12 races in a frame and 16 starts in a frame of 6 boats in 1 race in the pre-inspection mode. The stored registration data can be stored by pressing the measurement setting button and entering the race number with the 16 key.
The data of the selected race can be displayed on the screen as shown in FIGS. 5 to 8 and printed out as shown in FIGS. 9 to 14. You can also print out all races and selected races from the menu.

The information data of the image data display memory 12 is read in correspondence with the drawing position of, and the time is drawn based on the time data therein. Therefore, when the display position of the scale line 34 is moved, the time in the time display frame 36 is updated corresponding to the display position.

For example, FIG. 18 shows a display example of a screen on which the order of arrival of horse racing is determined and the record of time is confirmed.
This screen is an example of recording and confirming the time of arrival order 7. By aligning the scale line with the nose of horse number 6, "1'44" is displayed based on the time data corresponding to the display position of the scale line. "17" is displayed in the time display frame and the time field of the arrival order determination. In this way, the information data including the time data together with the image data is sequentially stored in the video memory in time series, and the time data in the information data is read by associating the position of the scale line and the position of the image data with each other. Since it is possible to display and record, the horse number is input in the order of arrival, the scale line is moved and operated, and the confirmation key is operated to confirm the order of arrival and record the time as shown in FIG. be able to.
