[Conventional technology]

2. Description of the Related Art Conventionally, as a device for recording a dynamic object as an image, a high-speed instantaneous multiplex image recording device described in JP-A-62-104279 is known. In this conventional example, for example, a golf club is swung, a large number of balls and clubs near the impact are projected in one frame (frame), and the still image is projected as a still image on a monitor at the moment of hitting the reflected one frame (frame). It is.

[Problem to be solved]

The conventional image recording apparatus is not suitable for capturing an image of a golf putter swing that does not operate at a high speed or an image of the moment of impact of a gate ball. Further, in the conventional example, the use of a high-speed strobe is indispensable, and it has not been possible to construct a device capable of clearly recording a slow-moving operation of the putting using a general video camera at low cost.

Therefore, an object of the present invention is to provide a multilayer image recording apparatus capable of capturing a dynamic object, for example, a putting operation in golf as a video of a multilayer image and displaying the movement of a head.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a video camera for photographing a dynamic object, and an automatic camera connected to the video camera and responsive to a dynamic object having a certain level of brightness or more entering the field of view of the camera. Upon receiving a trigger for detecting the brightness sensitivity of the brightness sensing means and the automatic brightness sensing means and a trigger signal from the trigger, the video signals of the dynamic object sent from the video camera are signaled at predetermined times, respectively. It comprises a control unit including a field memory for storing at a different address, and a display which receives a video signal stored at a different address sent from the field memory of the control unit and is displayed as a multilayer image on one screen. .

[Action]

In the present invention, for example, when a golf putting operation is recorded as a multilayer image, the video camera is started when the putter enters the subject range of the video camera. The head of the putter is white, and the trigger is actuated by the automatic brightness sensing means sensing the white head.
The trigger signal from the trigger is sent to the field memory, and the video signal of the dynamic object sent from the video camera in response to the trigger signal is stored at different addresses of the field memory at predetermined time intervals. Video signals stored at different addresses are sent from the field memory to the display, and the display displays the video signals on the screen as a multilayer image.

〔Example〕

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

The embodiment shown in FIG. 1 stores a putting operation as a dynamic object as a multilayer image. A video camera 3 is set up toward a dynamic object, that is, a putter 1 and a ball 2. When a trigger 4 detects a signal of a certain brightness or more, the video signal of the video camera is received and stored. A field memory 5 for sending an image is connected to the video camera 3. A microphone 7 is connected to the control unit 10 including the field memory 5. The details of the control unit 10 are as shown in FIG. 2, and an automatic brightness sensing means 8 is provided between the video camera 3 and the field memory 5, and the automatic brightness sensing means 8 is provided with a trigger 4
, And the field memory 5 is connected to the trigger 4. The microphone 7 is connected to the audio amplifier 9, the audio amplifier 9 is connected to the impact trigger 11, and the impact trigger 11 is connected to the field memory 5. The head of the putter 1 is painted white or pasted with white tape, the trigger 4 detects the putter head as a signal having a brightness higher than a certain level, and the trigger 4 activates the field memory 5. Here, the start of the video camera 3 may be performed manually, or another trigger may be provided so that the video camera 3 operates when the putter 1 passes a certain point. The video captured by the video camera 3 is converted into a digital signal, and when the trigger 4 detects a signal having a brightness equal to or higher than a certain level, the field memory 5 stores the video captured by the video camera 3. The field memory 5 receives the trigger signal from the trigger 4 and stores the video signal of the dynamic object sent from the video camera 3 at a predetermined address at a different address at each time. In this case, the white color is painted or affixed as described above in order for the head of the putter 1 and the ball 2 to output a signal of a brightness higher than a certain level as compared with the background. The field memory 5 is repeatedly stored every 1/60 second.

When the field memory 5 is stored according to the television scanning method, if the head of the putter 1 and the ball 2 having a signal of a certain level of brightness move from the opposite direction, the previous memory is The image is erased and the image is rewritten. Here, in the television scanning method, since a normal screen is scanned from the top to the bottom, a pattern 1 is used.
When watching the movement of the image, it does not match the human sense. Therefore, it is possible to rotate the cathode ray tube electrode by 90 ° and change the scanning from right to left, so that the display method can be adapted to the human sense.

The microphone 7 constitutes a sensor device. The microphone 7 as the sensor device captures a sound at the moment when the head of the putter 1 hits the ball 2 and sends the sound to the impact trigger 11 as a sensor signal. Is connected to the field memory 5,
When the signal from the impact trigger 11 is received, the storing operation is temporarily prohibited, the storing operation is performed after a lapse of a predetermined time, the movement of the ball is stored, the storing operation is prohibited again, and the storing operation is thereafter performed once or once. It is configured to return to the initial state after repeating several times. With this configuration, the hit ball 2 is prevented from being erased as an image. That is, it is possible to capture the trajectory of the head of the putter 1 and the ball 2 after the impact. As the sensor device, an optical sensor, a sound wave sensor, or the like can be used in addition to the microphone 7.

Since the field memory 5 is used as a memory device and is sequentially stored at the address of the field memory 5 in accordance with the movement of the putter 1, an image having a clear gradation can be output. The conventional apparatus described above is a method in which the video signal is superimposed on the same address, and cannot output the image of the head of the putter 1 or the ball 2 as having a clear gradation. In other words, in the present invention, a multi-layer image is formed and not a multiple image as in the related art.

In order to detect the speed of the ball 2 hit by the putter 1, the ball speed detecting section can be configured as shown in FIG. This has a first optical sensor 12 and a second optical sensor 13, and measures the distance that the ball passes through the distance between the first and second optical sensors 12, 13 and converts the distance into the ball speed, and displays the distance. The display of the speed of the ball can be visually checked by the unit 14. As the display unit 14, voice can be used. Such a ball speed detection unit can be configured to be operable with a battery power supply or a solar cell so that it can be used independently by itself. Further, the first and second optical sensors 12 and 13 are integrally formed so that the optical axes thereof are not deviated, and have a bridge-type structure that can be placed anywhere. In addition, the speed display is performed in m / sec,
In order to match the sense of a person, it is also possible to display the distance by which the ball rolls by multiplying by a certain constant.

In the case of putting, it is difficult for an amateur golfer to correctly obtain the sense of distance hit by the ball 2. The rolling distance of the ball 2 differs depending on the state of the green grass, the inclination, and the like. On the other hand, in the case of an amateur golfer, it is difficult to hit the ball 2 with a certain strength, and he does not grasp how much the ball 2 rolls if he hits it. So ball 2
The launching speed of the ball 2 is measured by a ball speed detector shown in FIG. 3 to quantify and confirm the launching strength of the ball 2.
If you hit it with a certain stroke, you can remember that you have a certain ball speed as your sense.
By grasping how much the ball 2 rolls in a certain stroke on the actual green, it is possible to gain a sense of distance by applying strength and strength by applying the sense.
Also, you can practice long putting even in a small indoor space.

The device shown in FIG. 4 is a measuring device around the cup (target) 15, which captures an image near the cup 15 with a video camera 16 and converts it into a digital signal. Is detected by image processing. That is, the video signal captured by the video camera 16 is sent to the control unit 17,
The control unit 17 displays the position of the cup 15 on the television monitor 18 in XY coordinates with the origin as the origin. Further, a signal from the control unit 17 is sent to a central processing unit (CPU) 19, and the central processing unit 19
Calculates the distance between the target and the ball 2 and processes it using a statistical method, and displays various information on the CRT 20.

The stop position of the hit ball 2 is automatically measured by the device shown in FIG. 4 to determine the distance from the ball to the target (cup), whether the target is on the right or left side, or the front or rear side of the target. By performing statistical processing using the CPU 19, it is possible to quantitatively express the skill of the batter, the habit of hitting the batter, the selection of a tool (putter) suitable for the batter, and the like.

〔The invention's effect〕

As described above, according to the present invention, a video camera that captures a dynamic object and an automatic camera that is connected to the video camera and that responds when a dynamic object having a certain brightness or more enters the field of view of the camera. Upon receiving a trigger for detecting the brightness sensitivity of the brightness sensing means and the automatic brightness sensing means and a trigger signal from the trigger, the video signals of the dynamic object sent from the video camera are signaled at predetermined times, respectively. Since the control unit includes a field memory for storing in a different address and a video signal stored in a different address sent from the field memory of the control unit and a display that is displayed as a multi-layer image on one screen,
An image with clear gradation is output. Also, if you use it for putting practice, you can directly see how to move the putter head to make sure the square can move correctly to the target direction, so you can practice correct putting Becomes Furthermore, it has a sensor that detects the moment when the putter impacts the ball, and an impact trigger that sends the signal detected by this sensor to the field memory.When the sensor detects the impact, the impact trigger receives the impact and receives the impact. A trigger signal is issued, and in response to this signal, the field memory stores the image of the impact sent from the video camera, and then temporarily stops the storing operation, then stores the image and stores the movement of the ball. In the case where the multi-layer image is displayed on one screen of the display by receiving the video signal stored in this manner at least once, the putter head comes to the previously stored ball position and a new image is formed. Even if it is stored, the image of the ball and putter head is also stored,
The trajectory of the ball and the putter head after being hit can be stored as an image.

Furthermore, by watching the image of the impact of the ball and the putter head, it is possible to know where the ball is hitting, that is, the hit point, and immediately know the degree of opening of the putter head at the time of impact. It becomes possible to train the positional relationship.
