2. Description of the Related Art Conventionally, as this type of image processing apparatus,
2. Description of the Related Art There is known a device in which a hitting form such as golf is constantly recorded using a magnetic tape, and a recorded signal is rewound and reproduced by inputting a reproduction signal.

[0003]

By the way, in hitting forms such as golf and baseball, 1.5 seconds before and 0.5 seconds after the moment of impact are the most important. On the other hand, the reproduction with continuous images during this period is not suitable for the analysis of the hitting form because the instantaneous form changing at an extremely fast speed cannot be sufficiently recognized. Therefore, the conventional image processing apparatus has a problem that the modification of the hitting foam is not effective.

In addition, when reproducing an image, it is necessary to rewind the recorded tape for reproduction, and therefore, it is easy to cause a failure, lack in durability, or take a long time to reproduce, resulting in poor operability. was there.

The present invention has been made by paying attention to the problems of the prior art as described above. An object of the present invention is to provide an image processing apparatus suitable for analyzing the movement of an object, capable of effectively modifying the movement of the object, having good operability, excellent durability, and reduced cost. .

[0006]

In order to achieve the above object, an image processing apparatus according to the present invention records a motion of an object based on a sensor for detecting the condition of the object and a signal from the sensor. Image recording means, storage means for storing the image data recorded by the image recording means at predetermined time intervals, display means for displaying the image data on the screen, and an image after the detection operation of the sensor. A control means is provided for storing the data for a predetermined time, then stopping the storage in the storage means, and controlling the stored image data to be displayed as a decomposed image on the display means.

[0007]

In this invention, the state of the object is detected by the sensor. Then, the image recording means records the state of the object based on the signal from the sensor. The image data recorded by the image recording means is stored in the storage means while being delimited at predetermined intervals. After storing the image data after the detection operation of the sensor for a predetermined time, the stored image data is displayed in a disassembled state by the display means.

Then, the disassembled images are continuously played on the screen of CRT7.
Be done. In addition, switch SW ₃When is pressed, the CRT7
A still image is displayed on the screen.

As shown in FIG. 2, the central processing unit (CP
U) 9 constitutes a control means, and the CPU 9 has a ROM
A (read only memory) 10 and a DRAM (dynamic random access memory) 11 are connected. R
The OM 10 stores a program for controlling the operation of the entire apparatus, and the DRAM 11 stores delimited still image data.

Further, a sound pressure sensor 8 is connected to the CPU 9, and a detection signal by a hitting sound when the ball 4 is hit with the golf club 2 is output to the CPU 9. Further, the camera 6 is connected to the CPU 9, and the golf fur 1
The image signal that captures the swing is output to the CPU 9.
Then, the CPU 9 decomposes the images before and after the impact and CRs when a predetermined time elapses after the signal of the impact sound is input.
Display it on the T7 screen. It should be noted that still image data is segmented and sequentially written in the DRAM 11 every 1/10 second, and the previous data is erased.

When the image processing apparatus is operating, C
The operation of the flowchart shown in FIG. 3 is performed under the control of the PU 9. That is, whether the switch SW ₁ is turned on is determined, when the switch SW ₁ is turned on, recording by the camera 6 is started, the still image data for every 1/10 seconds are sequentially stored in the DRAM11 (Steps S1 to S3).

Subsequently, it is judged whether or not the sound pressure sensor 8 has detected a hit sound, and when the hit sound is detected, the recording by the camera 6 is continued and a still image of 1/10 second per frame. Data for five frames are sequentially stored in the DRAM 11.
That is, as shown in FIG. 1A, still image data for every 1/10 second is sequentially stored in the DRAM 11. In this figure, the arrow indicates the storage portion of the current image data, and the portion without hatching indicates the portion for storing the image data thereafter. Next, as shown in FIG.
After 10 seconds, four frames of still image data for every 1/10 second are stored, and at that time, a signal from the sound pressure sensor 8 is input to the CPU 9. Then, FIG. 1 (c)
As shown in, the image data for 5 frames is input from that point.

The image data for 5 frames is stored in the DRAM.
When it is stored in 11, recording by the camera 6 is stopped,
A total of 20 from the image data (from -14 to 0 in the figure) 15 frames back from the point of the arrow in Fig. 1 (c) on the CRT7 screen.
The still image for the frame is played. During reproduction, the disassembled still image of one frame is reproduced at an interval of 3/10 to 4/10 seconds. Therefore, the golf player 1 can see while recognizing the decomposed images every 1/10 seconds. After that, as shown in FIG. 4, the reduced image of the still image for 20 frames is C
Simultaneously reproduced on one screen of RT7 (step S4 ~
S9). On the other hand, when the striking sound is not detected, the recording by the camera 6 is continued.

Next, whether or not the switch SW ₂ is turned ON is determined, when the switch SW ₂ is turned on, C
The image data is reproduced again on the screen of RT7 (steps S10 to S11). If the switch SW ₂ is not turned on after waiting for a fixed time, recording by the camera 6 is restarted. Then, whether or not the switch SW ₃ is turned on is determined, when the switch SW ₃ is turned on, a still image at the time of pushing the switch SW ₃ on the screen of CRT7 during playback screen is displayed ( Steps S12 to S1
3). On the other hand, if the switch SW ₃ is not turned on,
Playback on the CRT 7 continues.

As described above, in this embodiment, a plurality of still images before and after the moment of hitting with the golf club are reproduced as decomposed images after the swing is completed. Therefore, the golfer 1 can see that his / her form is rhythmically reproduced by the decomposed image immediately after the swing of the golf club 2 is completed. Since each of the decomposed still images can be clearly recognized, it is more effective for form analysis than continuous images. Therefore, the golf player 1 can clearly recognize the defects of his / her own foam and can effectively modify the foam.

Also, in this embodiment, the operation of rewinding and playing back the recorded tape as in the conventional case is not performed, and the DRA
Since the image data is stored in the element using M11 and 11a, the operability is excellent and the durability is also excellent.

Moreover, in order to obtain a continuous image, 1/6
While it is necessary to store still image data every 0 seconds in the DRAM 11, in this embodiment, still image data every 1/10 second may be stored in the DRAM 11. Therefore, the usage amount of the DRAM 11 can be reduced to 1/6 and the manufacturing cost can be reduced. (Second Embodiment) Next, an embodiment in which the present invention is embodied in an image processing apparatus for analyzing a batting form will be described with reference to FIGS.
