[51] Further, since the image data provided by image processing unit 202 can be stored on memory unit 206, which enables both previous swing motion and recent swing motion separately displayed on the display, it is possible to easily make a judgment on the degree of correction of swing motions.
[52] Figure 4 illustrates a schematic configuration diagram of another recorder for golf swing motion according to the present invention. The recorder for golf swing motion also minimizes power consumption and provides a conversion means of various functional modes at the same time, and it can perform functions as a DVR(Digital Video Recorder) and surveillance device, besides usage for golf.
[53] Describing the above mentioned in detail through the schematic configuration diagram of Figure 4, a power management unit 208 can be comprised therein additionally. Here, power management unit 208 manages electric power for the each component of the recorder for golf swing motion based on the detection signal of the sensor 110, that is, during the sleep mode of normal times, power management unit 208 generates wake-up signal, and simultaneously starts supplying power by detection signal of the sensor.
[54] Also, the recorder for golf swing motion further comprises a mode conversion unit
207 to provide various functional modes. It can work as a manless surveillance mode for storing image data pictured by camera when an object is detected based on detection signal of the sensor or can work as a remote surveillance mode for playing image in real time based on detection signal of the sensor.
[55] Here, the functional modes are set through the user interface, mode conversion unit

208 let only the components that corresponds to a certain functional mode wake-up, and simultaneously starts supplying power to reduce power consumption. An exemplary embodiment regarding use of the functional modes will be described afterwards.
[56] Figure 5 is an exemplified illustration regarding control of the number of frames for a recorder for golf swing motion according to the present invention. Referring to Figure 5 (a), there will be detection through the sensor when sensor and the head part of the club 110 are on the same line during golfer's down swing. Here, sensor 110 may comprise a light emission unit emitting lights and a light receiving unit collecting lights reflected by club head to detect a start point of the swing just before the impact. Besides, sensors that generate detection signal based on rapid change in the intensity of light, approach of metallic object, or change in sound-level also can be used.
[57] As such, based on detection signal of sensor 110, the recorder for golf swing motion controls camera to picture with the increased number of frames for golfer's swing motion compared to before the sensor's detection, and gets image data for golfer's swing motion after the sensor's detection.
[58] Figure 5 (b) is an illustration of a result of an increment in the number of frames pictured by the recorder for golf swing motion according to the present invention. The upper part of the illustration shows images pictured with the normal number of frames, the lower part shows image frames that are increased in number after the recorder for golf swing motion acquires sensor's detection signal compared to normal frames pictured. Describing in detail with reference to the illustration, during the procedure of down swing from the top swing where the club head locates at the highest point, when the club head and the sensor be on the straight line, the sensor provides detection signal with the recorder for golf swing motion. As such, the recorder for golf swing motion, through control of the camera, increase the number of frames after the sensor's detection to transcribe the real-time movement at the moment near the impact in the frames increased in number as illustrated in the illustration so that it shows image data with clear image quality and smooth continuous movement.
[59] Here, as for the part where the club head is located in the straight line with the sensor in back swing during the progress toward top swing, the recorder for golf swing motion is configured to ignore the first detection signal of the sensor and can prevent errors from occurring in working process.
[60] As described above, the reason for increasing the number of frames from just prior to the impact is to precisely observe information about how correctly the impact on the golf ball was performed, and to make the image just prior to the impact clear and departmentalized to easily determine thereof since incorrectness of the swing motion just prior to the impact is a determinant of incorrectness of entire impact.
[61] While, the present invention can be used for various purposes that is not limited to golf purpose, and it can be applied to the similar sports where impact and the specific posture is important. For example, it can be used for sports that require variety of hitting such as base ball where swing form and pitching form is considered to be important. Besides applying the present invention to industrial fields, it can be used for monitoring functional processes or accuracy for specific mechanical movement.
[62] Hereinafter, regarding the use of the functional modes, exemplary embodiments of the recorder for golf swing motion according to the present invention will be described.
