Reference numeral 7 denotes a writing circuit for storing the digital video signal from the A / D conversion circuit 6 in a memory. A memory unit for storing digital information data; 9 a read circuit for scanning and converting digital video data and digital information data stored in the memory unit 8; 10 a time generator;
Reference numeral 11 denotes an address control unit that controls writing and reading of the memory unit 8, reference numeral 12 denotes a character generator, and reference numeral 13 denotes a central processing unit (hereinafter, referred to as a CPU).

A one-dimensional video signal is obtained by capturing an image of a moving body 2 passing on a judgment reference line 1 as a subject by a linear sensor camera 3 having a lens 4. Linear sensor camera 3
Is output to the image recording unit 5, and the video signal is A /
The data is converted into a digital video signal by the D conversion circuit 6, and is written and stored in the memory unit 8 via the writing circuit 7. The digital video signal from the linear sensor camera 3 is stored in the memory unit 8, and at the same time, for example, a time generator 10 for superimposing and displaying the elapsed time from the start on the image and characters, symbols, and determination lines are displayed on the image. A digital information signal from the character generator 12 for superimposition is stored.

The readout circuit 9 scan-converts a portion necessary for determining the arrival order and time from the digital video data and digital information data stored in the memory section 8 to convert the portion into a two-dimensional video signal and an information signal. Read out and output to the video monitor 14. The video monitor 14 displays an image necessary for determining the arrival order and time from the two-dimensional video signal and the information signal input from the readout circuit 9.

The write circuit 7, the memory section 8, the read circuit 9 and the like are controlled by the control signal of the address control section 11 to
Control of writing and reading is performed. In addition, operating device 1
The entire apparatus is managed by the CPU 13, including various controls based on selection of means for recording and reading signals such as video signals and information signals. Note that the reference timer start signal 17 and the memory capture signal 1
8 and so on.

Here, the concept of storing the video signal captured by the linear sensor camera 3 in the image recording section 5 mainly including the memory section 8 will be described with reference to FIG. The memory unit 8 mainly includes an image memory 8A that stores the input digital video signals, an information memory 8B that stores digital information signals such as an elapsed time from the start and an event.
And a display memory 8C for recording an image to be synthesized and displayed on a video monitor. The image memory 8A and the information memory 8B each have a capacity of 24 pages. The page shown here expresses a range that can be displayed on one screen of the video monitor as one page, but is continuous on an actual memory. It is assumed that the display memory 8C has a capacity for one page.

As shown in FIG. 2, the image memory 8A and the information memory 8B in the memory section 8 are all controlled to correspond to one video signal input by the selection signal from the operation device 19, and The digital video signal of the moving object 2 passing through the
7 together with the digital information signal of the character generator 12, for example, the event or title of the game, and the like from the memory end are sequentially stored in chronological order. Of the stored digital video data, digital information data related to digital video data corresponding to an image required for determination is stored in a display memory 8C, read out to a readout circuit 9, and scanned and converted to an image of a video signal. Is displayed on the video monitor 14.

Since the digital video signals sequentially stored in the memory section 8 in time series are one-dimensional digital video signals from the linear sensor camera 3, the state in the memory shown in FIG. 1 is shown in a state where a one-dimensional digital video signal is scan-converted into an image of a normal two-dimensional television system.

The image stored in the memory unit 8 based on the above concept is assumed to be five pages. As shown in FIG.
The normal image displayed on 4 is a continuous image memory 8
A and one page of the information memory 8B are displayed in the display memory 8C.
And only one page of the image memory 8A and the information memory 8B can be confirmed on the video monitor 14. Therefore, in order to confirm all images, the image memory 8A and the information memory 8 displayed on the video monitor 14 are controlled by a control signal from the operation device 19.
By moving the display location of B and repeating the operation of writing to the display memory 8C, the screen of the video monitor 14 is scrolled. Ordinary arrival order and time determination are performed on this screen.

In the present invention, the digital data stored in the image memory 8A and the information memory 8B, which have been continuously stored, are converted into four pixels in the horizontal direction as shown in FIG. 1 pixel for each, 4 in the vertical direction
One pixel is read out for each pixel and written to the display memory 8C, and this is repeated for six pages, thereby creating an image on the display memory 8C which is thinned and reduced by ４ in both the vertical and horizontal directions for six pages. When writing to the display memory 8C,
Pages 1 to 3 are written in the upper part of the screen, and pages 4 to 6 are written in the lower part of the screen. The conceptual diagram when the image data in the display memory 8C is displayed on the video monitor is as shown in FIG. The screen configuration has a reduced page size.

The digital data in the display memory 8C is read out to the readout circuit 9 and the scan-converted video signal is displayed on the video monitor 14. As a result, in the case of recorded images of six pages or less, all the images can be displayed in one screen. For images with more pages, a similar method is used to display the next 7 to 12 pages, 13 to 18 pages, and 19 to 24 pages on one screen in accordance with a control signal from the operating device 11. It can be carried out. Therefore, since all the stored images for the five pages can be displayed on one screen on the video monitor 14, it is necessary to confirm all the moving objects 2 that have passed 1 on the determination reference line from the one screen image. Can be.

Since the size is reduced to 1/4 in both the vertical and horizontal directions,
Actually, 16 pages can be displayed on the video monitor 14. Here, the number of pages to be displayed on the video monitor 14 is set to be 6 pages. To hide,
This is because an attempt was made to arrange them in the center of the screen for easy viewing. As for the video printer 16 and the like that can display all the surrounding images, 16 pages are displayed. In the above embodiment, the display is reduced to 1/4 in both the vertical and horizontal directions, but another reduction ratio may be used.
