Abstract

PROBLEM TO BE SOLVED: To repeatedly display the clear and full-color pitching video images of a pitcher whose movement is smooth by enlarging a screen by joining plural television receivers, compressing the pitching video images of the pitcher in high density, recording them in a pitching video image recording medium and repeatedly reading them without contact. SOLUTION: A CD-ROM 41 records compressed and encoded digital image data, a CPU 43 interactively reads the digital image data of the CD-ROM 41 to a memory 42 and a decoder 44 decodes the read encoded digital image data at a high speed. A memory data controller 47 writes the decoded digital image data in the memory 45 for chrominance signals and the memory 46 for luminance signals and a memory address controller 48 divides the written data into the three screens and takes them out while controlling addresses matched with horizontal and vertical synchronizing signals. D/A converters 49, 50 and 51 convert taken-out digital image data to analog RGB signals and output them to monitor televisions 21, 22 and 23.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a batting practice machine provided with a video device for displaying a pitcher's pitching image in synchronization with a pitching machine's pitching, and more particularly to the imaging device.

[0002]

Conventionally, as a video device for a batting practice machine, a large projector or LED has been used.
Boards were used. Since a projector magnifies an image with a lens and projects it on a screen, it is difficult to see in a bright place, the image is not clear, and the device is large and expensive. Further, when the video source is acquired from a video device such as a video deck, the same video is repeatedly reproduced, so that the recording medium is worn and durability becomes a problem.

Since the LED board has an extremely small number of pixels as compared with a video image, the texture of the image is rough and lacks in detail. The display color is limited to a single color or three colors because full color is not economically viable. Further, when the video source is obtained from the IC card, the number of display frames of the video is small due to the limitation of the memory capacity, so that the motion is rough and jerky.

Although a television receiver is the most suitable means for realizing a clear and full-color image at low cost, it is difficult to enlarge the screen due to the nature of the cathode ray tube. Therefore, the present invention displays a clear, full-color pitcher pitching image by connecting a plurality of television receivers and enlarging the screen.

A full-color still image having a size of 640 × 480 dots has a size of about 0.9 MB. In order to make the motion of a moving image smoother and more natural, it is necessary to display 30 frames per second, which requires reading and displaying as much as 27 Mbytes of data per second. It is far beyond the processing capacity of a personal computer. Therefore, the present invention makes it possible to read out by a CD-ROM by compressing an image of 30 frames up to a size of 150 Kbytes per second by making full use of digital moving image technology by the latest computer. As a result, the pitcher's pitched image is smooth in motion and close to natural.

Further, by using a CD-ROM as the recording medium for the pitcher's pitched image, the problem of durability of the recording medium due to non-contact reading of moving images and repeated reading is solved.

According to the present invention, a plurality of television receivers are connected to each other to enlarge a screen, a pitcher's pitched image is compressed at a high density, recorded on a pitched image recording medium, and repeatedly read out in a non-contact manner. It is intended to display a smooth, clear, full-color pitcher pitch image repeatedly.

[0008]

In order to achieve the above object, the present invention is configured as follows.

That is, the invention of claim 1 is a batting practice machine equipped with an image device for displaying a pitcher's pitching image in synchronization with the pitching machine's pitching, and a plurality of television sets are connected to form a large screen. A multi-screen device, a pitched video recording medium for compressing and recording the moving image of the pitched video at high density, and a compressed moving image restoration for restoring the high density compressed moving image read from the pitched video recording medium at high speed. Means and screen dividing means for dividing the moving image restored by the compressed moving image restoring means into the plurality of television receivers, and repeatedly displaying the pitcher's pitch image on the multi-screen device. It is a video device of a batting training machine. The invention of claim 2 is the video device of the batting practice machine according to claim 1, wherein the pitch video recording medium is a non-contact readable recording medium.

CPU 43 of controller 4
Reads out the first pitching start image from the CD-ROM 41, and superimposes it on the pitching start message and the number of pitches set according to the amount of the fee and displays it on the display device 2.

After that, the CPU 43 starts the pitching machine 1
The control switch 17 is turned on to put itself in a state of waiting for a signal from the pitch sensor 14. When the CPU 43 receives the signal from the pitch sensor 14, the CD-ROM
The next pitching image is read out from 41, and the number obtained by counting down the number of pitches is superimposed and displayed.

The CPU 43 turns off the control switch 17 of the pitching machine 1 and the CD-ROM 41 when the countdown display of the number of pitches becomes zero.
The final pitching end image is read from, and the pitching end message is superposed and displayed on the display device 2.

FIG. 4 shows a block diagram of a digital image data recording apparatus for compressing a pitcher's pitched image at a high density and recording it on a pitched image recording medium. The digital image data recording device is a video camera 61 or a video deck 62.
The video signal of the video equipment such as the above is transmitted via the video capture board 63 to the image display memory (VR) of the personal computer 64.
AM) and digitize. While displaying the digitized video signal on the display of the personal computer, adjust the image size and display position, and then CD-ROM6
5 and the like are recorded on a recording medium such as 5 by compressing the moving image.

The controller 4 of the batting practice machine embodying the present invention divides one image into three by the built-in memory address controller 48 and displays them on each monitor television 21, 22, 23. As shown, the same video source is used for three PCs 71, 7
It is also possible to read out simultaneously by 2, 73 and divide one image into three, and share the images by the three personal computers 71, 72, 73 and display them on the monitor televisions 21, 22, 23.
