Abstract

PURPOSE:To remarkably increase practice effects, by reviving the exercise forms just after play by a TV monitor and other and checking the forms by the player himself. CONSTITUTION:Image signals of golf swings for instance taken by a video camera 10 are converted to digital signals by A/D converter 20. And further, the same signals are simultaneously transmitted to the whole video memories 31a, 31e by a distribution amplifier 30. On the other hand CPU 60 is automatically sequenced according to a preset delay time. And it is directed at which time point the video signals should be memorized respectively against each video memory 31a, 31e. The change-over instruction of the memories to take out video memories 31a or 31e by a matrix switcher 32 is output to the matrix switcher 32. And the digital signal is converted to the original analog video signal by the D/A converter 40 and reproduced as an image by a TV monitor 50.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] This invention relates to an athletic form checker that allows athletes of any sport to check their athletic form immediately after playing.

[Conventional technology]

When practicing various sports, a practice method in which a mirror, a video camera, a video tape recorder, etc. are used to visually check the movement form (e.g. golf swing) at the same time as the exercise or after a while. may be adopted.

[Problem that the invention seeks to solve]

However, when looking in the mirror to check your form, you must always keep your eyes facing the mirror, and in actual practice, it may become difficult to hit a golf ball, or your form may become difficult. It may cause it to collapse. Also, when using a video camera and video tape recorder, checking can only be done after performing operations such as rewinding or cueing, which takes a long time and is not a very effective means for checking movement form. There are other problems.

The present invention was devised in view of the above-mentioned problems in the prior art, and it is an object of the present invention to provide a device that allows a player to check his/her athletic form immediately after playing.

[Means for Solving the Problems] Therefore, the exercise form checker of the present invention visually captures the athlete's exercise form, inputs it as a video signal, A/D converts it, and stores it in the memory. After a set time has elapsed, the video signal is taken out from the memory, subjected to D/A conversion, and the video signal is reproduced visually.

The above configuration will be explained in more detail with reference to FIGS. 1(a) and 1(b) as follows.

That is, the athletic form of the athlete is captured by a video camera (1), the video signal is converted into a digital signal by an A/D converter (2), and is stored in memory X (3a) as shown in FIG. Make me remember. Then, as shown in FIG. 3B, the input light of the digital signal is switched to the memory Y (3b). On the other hand, the digital signal stored in the memory
5) is played.

At this time, if the storage capacity of the memory x Y (3a) (3b) is adjusted in accordance with the delay time to be set, while the memory X (3a) is storing the signal, the memory Y ( 3b) outputs a signal, and memory Y (
By alternately repeating the signal storage/signal output work in which memory X (3a) outputs while memory Become.

Specific examples of the present invention will be described below.

FIG. 2 is a circuit diagram showing the circuit configuration of a golf swing checker according to an embodiment of the present invention.

The device of this embodiment is roughly divided into a video signal input circuit A that captures images, a memory circuit B for storing signals whose signal input/output section has a special circuit configuration, and a video signal input circuit A that captures images. and a control circuit that performs a storage operation control command for the input signal of the memory circuit B and a signal output control command according to a set delay time.

The video signal input circuit A includes a video camera (10);
The video camera (10) captures the golfer's golf swing, and the A/D converter (20) converts the video signal into a digital signal.

The memory circuit B includes a distribution amplifier (
30), video memories (31a) to (31e),
The distribution amplifier (30) branches the digital signal converted by the A/D converter (20) according to the number of video memories (31a) to (31e). , the same signal is simultaneously output to these video memories (31a) to (31e), and the matrix switcher (32) is connected to the output side of the video memories (31a) to (31e), 31a) to (3
The signal extraction from 1e) is switched. In each of the video memories (31a) to (31e), the storage operation of input signals from the distribution amplifier (30) is controlled by control commands from a control circuit, which will be described later, and input signals are simultaneously input to each memory. Of the digitally converted video signals, the signals forming the first screen and the second screen are stored in the video memory (31a), and the signals of the third screen and the white screen are stored in the video memory (31b). Similarly, every moment of continuous video is stored as a digital signal in each video memory (31a) to (31e). Similarly, a matrix switcher (
The switching of taking out digital signals from the video memories (31a) to (31e) by 32) is also controlled by the control command of the control circuit, taking out the signals of the -th screen and the second screen from the video memory (31a), and then The signal extraction switching on the memory side is performed by switching to the video memory (31b) and extracting the third side and white screen signals from there.

The reproduction circuit C includes a D/A converter (40) that converts a digital signal into an analog signal, and a TV monitor (50) that reproduces an analog video signal as a video, which are sequentially connected by the aforementioned matrix switcher (32). The digital signals taken out from the video memories (31a) to (31e) are converted into analog video signals by the D/A converter (40), and further converted into analog video signals by the TV monitor (
50), this will be played back as an actual video.

The control circuit includes a CPU (60) equipped with a delay time setting interface (61), and a CPU (60) equipped with a delay time setting interface (61).

) to (31e), the output timing of the storage control commands may be set narrowly to increase the number of video recording screens.

Furthermore, this golf swing checker uses a CPU (60
) by changing the sequence as necessary to provide a loop repeat function, allowing you to repeat the scene you want to see as many times as you like.

〔Effect of the invention〕

According to the motion form checker of the present invention detailed above,
Immediately after playing, the movement form is reproduced as an image on a TV monitor, etc., and the athlete can check the form, and while the athlete's own body is memorizing the series of movements, the athlete can check the form. This makes it possible to dramatically increase the effectiveness of practice.
