DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image judging apparatus used for judging the order of arrival of horse races, wheel races, boat races, auto races, etc., and judging the shape and characters of an object moving at high speed.

[0002]

2. Description of the Related Art Slit cameras have been widely used for determining the order of arrival of, for example, horse races, bicycle races, boat races, and auto races, but this method requires a certain amount of time for film development and the like. Therefore, there is a problem that quick arrival order cannot be determined. Therefore, the present applicant has proposed an image determination apparatus that can perform a determination operation quickly and easily by converting an image into an electric signal and processing the image with digital image data (for example, Japanese Patent Application Laid-Open No. 31
No. 6986, JP-A-63-316987, JP-A-1-174174, JP-B-4-50792, and JP-B-7-79470-2.

In the video judging device which has been already proposed, a moving object passing on a goal line is vertically imaged by a line sensor camera having a plurality of photosensitive elements arranged one-dimensionally. First, the analog electric signal output from the line sensor camera is sequentially converted into digital image data, and image data for a predetermined time is written in a continuous video memory for a plurality of screens. Is read out, converted to an analog video signal, and displayed on a television monitor. In this case, the line sensor scan speed (accumulation time) is set to 1/1000 second in order to make it possible to determine the order of arrival in various sports such as horse races and boat races. While displaying the image, time-lapse image data for 16 seconds every 1/1000 second, that is, image data for 16 screens is stored in the memory. The judge judges and confirms the arrival order and the arrival time while scrolling the image of the stored time back and forth with the scroll lever of the operation unit.

[0004]

By the way, in the above-mentioned image judging device, if the scan speed of the line sensor camera and the moving speed of the moving object do not match, the image data for one screen is read from the video memory and displayed on the monitor. In such a case, an object image that expands or contracts in the horizontal direction is obtained. In view of this, the present applicant has proposed a device for extending or contracting a still image on a monitor in the horizontal direction so that it can be corrected in accordance with the original object image (for example, see Japanese Patent Application Laid-Open No. Sho 63-3).
No. 16986). However, in the device according to this proposal, the starting position of the scanning line at the left end of the monitor is used as a base point, the reading start position of the video memory, that is, the display start address is fixed, the clock frequency is changed, and the number of pixels is changed. The movement display is right-justified, causing various inconveniences.

[0005] In particular, when the moving direction of the moving object is to the right of the screen, it is normal to display a judgment line to the right of the center of the screen. The judgment line moves according to the expansion ratio.
However, in general, the determination line often does not want to be moved on the screen, and in order to move the determination line to the same position as the previous screen, a scroll operation of the image is required, which makes the operation cumbersome. is there. For example, if it is desired to perform an overall arrival order determination including the presence or absence of a moving object behind by expanding the field of view, a scroll operation of the image to the right is required, and the resolution of the determination line portion is increased. In such a case, since the image is relatively shifted to the right, a scroll operation to the left is necessary.

[0006]

FIG. 19 is a diagram showing an example of expansion and contraction from a display image and its reference position, and FIG. 20 is a diagram for explaining calculation of a read start address in image expansion and contraction processing. Now, as shown in FIG. 19A, when the display range is extended for a moving image a, b moving from left to right in the figure and a scale image m displayed at the tip of the moving object a, the scale line is extended. If m is fixed and the display range is extended, as shown in FIG. 19B, if there is a moving object c behind the moving objects a and b, the moving object c can be taken into the display range. However, if the display start address is fixed and the display range is extended, even if there is a moving object c behind the moving objects a and b as shown in FIG. 19C, the moving object c is taken into the display range. Can not do. The present invention performs the expansion and contraction display of an image as shown in FIG. 19B of the former, and the conventional method employs the former method of FIG. 19C.
The expansion and contraction display of the image shown in FIG. Therefore, in the present invention, the image data display memory 13 and the time display memory 1 are set based on the designated intermediate position of the display image.
Then, the image data and the drawing data are read out by calculating the horizontal read start address of No. 4.

The expansion and contraction of an image in the image display dot number variable system is performed by using a PLL circuit to obtain phase synchronization based on the edge of a television horizontal synchronization signal, and changing the number of dividers of the PLL circuit to change the television horizontal dot clock frequency. Changes the number of pixels. In the conventional method, the display start address is fixed, the TV horizontal dot clock frequency is changed, and the number of pixels is changed with the start position of the scanning line (left side of the monitor) as a base point. In this way, the display is stretched right on the screen.

In the present invention, the control circuit 22 manages the number of dividers of the PLL circuit, calculates a display start address for a change in the horizontal dot clock frequency with the scale line m as a base point, and changes the display start address to change the image data. The image data and the drawing data are read from the display memory 13 and the time display memory 14. For example, as shown in FIG. 20, the PLL CLOCK # 1 of FIG.
When image data is read and displayed by changing the TV horizontal dot clock frequency to L CLOCK # 2, the display start address is s, and the address of the scale line serving as the base point is m.
With the new (G) MEMORY DATA, the display start address s' can be calculated as follows.

The display start address s1 of SCALE DATA, the display start address s of MEMORY DATA and the address m of the scale line are managed by the control circuit, and the pixels from the display start address s1 of SCALE DATA to the address m of the scale line are controlled. The number, the frequency of each of the CLOCKs # 1 and 2, and the video display section are obtained. From this, the ratio of the number of effective pixels on the screen is obtained, and a new SCALE DATA is calculated based on the ratio.
Display start address s1 'and MEMORY DA
The display start address s' of the TA is corrected. Of course SC
ALE DATA display start address s1 'and M
It goes without saying that the algorithm for calculating the display start address s' of EMORY DATA is not limited to the above procedure, but can be changed as appropriate.

The present invention is not limited to the above embodiment, but can be variously modified. For example, in the above embodiment, the number of pixels of the color line sensor is set to 17
Although the number of pixels is 28 and the display area of the television monitor is 1035 pixels, the number of pixels of the color line sensor may be further increased. Further, the display position of the scale line is fixed and the display start address is changed. However, the display position at the center of the screen may be fixed and the display start address may be changed. The present invention may be applied not only to the expansion and contraction of pixels but also to the case of performing expansion and contraction by performing pixel thinning and interpolation. Further, it may be combined with a method of thinning out an image in line units in the vertical direction. That is, in the color line sensor of 1728 pixels as described above, the entire object image of the moving object passing through the goal line is captured from the inside to the outside and stored in the video memory. Transfers the image data of the continuous lines within the range that can be displayed on one screen to the display memory, and reads out the image data from the display memory to display the inner still image. When displaying the outside that does not fall within this range, the read address of the display memory is moved downward by scrolling to display an image shifted to the outside, or the half-thinned line in the thinning mode is displayed. By reading the image data from the display memory, the entire still image including the inside and outside of the goal is displayed in 864 lines.

[0053]

As is apparent from the above description, according to the present invention, the horizontal direction of the video memory in the horizontal direction is determined based on the designated intermediate position of the image, such as the center of the monitor screen or the scale line displayed on the screen. Since the image data is read by calculating the read start address, the screen can be expanded or contracted with the position of interest on the monitor screen fixed. Therefore,
Since the screen is expanded and contracted with the position of interest fixed both when increasing the resolution and when expanding the field of view, a desired display screen can be obtained by a simple operation of expanding and contracting.
