Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is intended for recording, for example, golf, baseball, tennis, soccer, kabuki, karate, and science experiments in which sound is generated during a series of operations. The present invention relates to a system for recording and reproducing so that a series of operations can be easily grasped.

[0002]

2. Description of the Related Art For example, in order to improve the hitting ability of tennis, the inventor of the present invention is better than grasping the instantaneous movement of the hitting ball.
I have come to realize that it is more important to understand how a series of actions are performed. This is considered to be supported by the fact that, for example, in sports magazines, disassembled photographs of the actions of good people are posted.

However, the disassembled photographs of the movements published in magazines belong to others, and it is necessary to confirm by themselves what the essential movement of oneself is.
Therefore, conventionally, the operation of oneself is confirmed by the following method.

The first method is a method of confirming the operation by having a third party see it. The second method is a method of recording a motion by utilizing a video or the like.

[0005]

The above-mentioned first method can expect appropriate advice if the third party knows the model behavior, but is often useless otherwise. In addition, there is a problem that there are many restrictions on execution because a third party who can give appropriate advice is not always close.

On the other hand, the above-mentioned second method can be easily carried out unlike the first method, but has the following problems and is not practically practical. The first problem is
The point is that it is difficult to quickly confirm where the important part of a series of actions is recorded. This is because, for example, in the swing of a golf club, there is a consciousness of trying to swing after concentrating, but the time until the concentration varies depending on the conditions even for the same person.

The second problem is that when it is desired to check the important part of the motion by slowing down, the frame advance of the video takes too long (the time interval is too long), and the information of the important part falls. There is something that happens. This becomes remarkable in sports such as golf clubs and tennis racket swings where quick movements are performed.

The present invention has been made in view of the above circumstances, and an image to be recorded in which sound is generated during a series of operations is recorded and can be reproduced in a form that is easy for the user to use. It is an object to provide a reproduction system.
