[

The time from the time point (t (s)) at which the video was started to the actual impact time point t (vi) in the video is the video impact time (VIDEO IMPACT TIME).

For example, the time t (f) at which the operation of the imaging unit 120 of the mobile device 100 is stopped may be set to about one second after the time t (i ').

In order for the processor 160 to synchronize the first image IMG and the second image TR, a criterion for matching the two images is required, and the criterion may be a real impact time point of the golf ball and the golf ball Lt; / RTI >

The processor 160 may use the starting point t (o) of the sensor device 200 and the impact point t (i) of the golf ball and the golf ball sensed by the sensor device 200, 1 image IMG and the second image TR.

In FIG. 4, communication delays between the sensor device 200 and the mobile device 100 are ignored for convenience of explanation. Therefore, it is assumed that the start time t (o) of the sensor device 200 and the start time t (o ') of the start of the sensor device 200 are equal to each other .

When the time taken for the mobile device 100 to receive the start signal of the sensor device 200 and turn on the imaging unit 120 of the mobile device 100 is DS, Can be obtained as shown in Equation (1).

[Equation 1]

The time from t (o) to t (i) is the sensor operating time (SENSOR ELAPSED TIME).

T (o ') in the timeline of the mobile device 100 is the start time of the mobile device 100 at the time when the sensor start signal is received at the mobile device 100 and t (s) T (i ') is a time point when the mobile device 100 learns that the sensor device 200 senses the impact, and t (i') is a time when the mobile device 100 recognizes the impact (f) is a time point at which the operation of the imaging unit 120 of the mobile device 100 is stopped. t (vi) is the actual impact time point of the golf ball and the golf ball in the video shot by the imaging unit 120. [

The time from the time point (t (s)) at which the video was started to the actual impact time point t (vi) in the video is the video impact time (VIDEO IMPACT TIME).

In order for the processor 160 to synchronize the first image IMG and the second image TR, a criterion for matching the two images is required, and the criterion may be a real impact time point of the golf ball and the golf ball Lt; / RTI >

The processor 160 may use the starting point t (o) of the sensor device 200 and the impact point t (i) of the golf ball and the golf ball sensed by the sensor device 200, 1 image IMG and the second image TR.

The processor 160 determines the time t (i) at which the sensor device 200 senses the impact of the golf ball and the golf ball to synchronize the first image IMG and the second image TR, ) To find the actual impact time point t (vi) in the video.

In FIG. 5, the calculation delay of the sensor device 200 for calculating the actual impact time t (oi) of the golf ball and the golf ball is assumed to be DCA. In other words, the DCA is a time taken to detect the actual impact point t (oi) from the actual impact point in time t (oi) in the sensor device 200. Therefore, the actual impact time t (oi) of the golf ball and the golf ball is different from the time t (i) at which the impact is sensed by the sensor device 200.

In FIG. 5, it is assumed that the communication delay between the sensor device 200 and the mobile device 100 is DCO. In other words, the DCO is a time taken for the mobile device 100 to receive the start signal ST of the sensor device 200. [ Therefore, the start time t (o) of the sensor device 200 and the start time t (o ') of the start time of the sensor device 200 are different from each other.

When the time taken for the mobile device 100 to receive the start signal of the sensor device 200 and turn on the imaging unit 120 of the mobile device 100 is DS, Can be obtained as shown in Equation (2).

&Quot; (2) "

Video Impact Time = t (i) - t (o) - DS - DCA - DCO

Since the mobile device 100 can know the turn-on time t (s) of the image pickup unit 120 when the video impact time is obtained, the actual impact time t (vi) ) Can be obtained.

Upon obtaining the actual impact time point t (vi) in the video, the processor 160 determines whether the actual impact point in time t (vi) The image can be cut and output to the display unit 140. For example, a may be 2 seconds and b may be 1 second.

The calculation delay (DCA) of the sensor device 200 for calculating the actual impact time t (oi) of the golf ball and the golf ball in the present embodiment, the calculation delay (DCA) of the sensor device 200, Of the mobile device 100 and a start delay DS (DSO) for the mobile device 100 to receive the start signal of the sensor device 200 and turn on the imaging part 120 of the mobile device 100, (DCA), the communication delay (DCO), and the start delay (DS) are relatively small, it is possible to calculate the video impact time.

FIG. 6 is a conceptual diagram showing an operation of a seek bar when the first image IMG or the second image TR of the display unit 140 of FIG. 3 is enlarged.

1 to 6, the first image IMG or the second image TR may be displayed on the display unit 140 in such a manner that two fingers are brought into contact with each other and a distance between the fingers is increased, Can be enlarged and displayed.

When the first image IMG is enlarged, the second image TR may be enlarged at the same rate as the first image IMG. Similarly, when the second image TR is enlarged, the first image IMG may be enlarged at the same rate as the second image TR.

When the first image IMG or the second image TR is enlarged and the first image IMG or the second image TR is not enlarged Can be reduced.

That is, when the user enlarges the first image IMG or the second image TR, it means that he wants a detailed analysis of the golf swing motion. Therefore, It is possible to reduce the moving distance of the seek bar SB as compared with the amount of sweeping the swinging motion of the swinging bar SB.

In other words, when the screen is enlarged, even if the user drags the seek bar SB by a distance of x, the actual moving distance of the seek bar SB becomes smaller than x.

For example, the total length of the seek bar SB corresponds to a time of n seconds, and the total length of the seek bar SB is m centimeters, and the first image IMG or the second image TR When the size of the seek bar is enlarged by z, when moving the seek bar by x centimeters, the travel distance of the seek bar can be calculated according to Equation (3).

&Quot; (3) "

(Sec) of the seek bar =? * (X / z) * (n / m)

Here, the? May be a sensitivity function varying according to an enlargement magnification z of the first image IMG or the second image TR. Can be defined according to Equation (4).

&Quot; (4) "

beta = e ^{k * (z-1)}

That is, when z = 1, β is 1, and as z increases, β exponentially increases. In this case, k is a sensitivity constant.

When the size of the first image IMG or the second image TR is enlarged by z, when the seek bar SB is moved to the right by a maximum amount, the maximum distance may be m centimeters, The travel distance (sec) of the seek bar at that time can be defined according to equation (5)

&Quot; (5) "

The maximum travel distance (sec) of the seek bar = β * (n / z)

Similarly, when the size of the first image IMG or the second image TR is enlarged by z, when the seek bar SB is moved to the left by a maximum amount, the maximum distance may be m centimeters And the travel distance (sec) of the seek bar at that time is expressed by Equation (5).

According to the present embodiment, in a state where the first image IMG and the second image TR are synchronized, the user can enlarge a portion to be analyzed in detail for swing motion, The moving distance (sec) of the bar SB is finely adjusted, so that the swing motion can be accurately diagnosed.
