If start the Golfing practice device 10 of present embodiment, the positive photographed images producing with DV 16 is stored in the positive buffer circle 26 of using successively, and the photographed images that the back side produces with DV 17 is stored in buffer circle 27 for the back side successively.

If utilizing front makes a video recording with DV 16, in the moment of obtaining new images, be overwritten in positive with in the oldest photographed images of buffer circle 26, and, the new photographed images that front is produced with DV 16 upgrade be successively stored in positive with in buffer circle 26, constantly store predefined during in, the positive photographed images producing with DV 16.

Similarly, if utilizing the back side makes a video recording with DV 17, in the moment of obtaining new images, be overwritten in the back side with in the oldest photographed images of buffer circle 27, and, the new photographed images that the back side is produced with DV 17 is upgraded successively and is stored in the back side with in buffer circle 27, constantly store predefined during in, photographed images that the back side produces with DV 17.

About buffer circle 26 and the setting of the memory period of buffer circle 27 for the back side for front, according to its memory capacity, be set as for example storing the photographed images between 4 seconds.

In response to player, bat, CPU30 produces and front is used to the triggering signal of buffer circle 27 with buffer circle 26 and the back side, based on triggering signal, stop the storage of the new photographed images in each buffer circle, extract the video image of player's best attack action, and reset and practise for player.That is, CPU30 plays the effect as dynamic image extraction unit.

In the present embodiment, after producing triggering signal, after delay stipulated time, stop the storage of the new photographed images in each buffer circle.The processing time of this time delay based on being obtained by the processing time timing 24a of portion timing decided.That is, from the end of photographed images, light the moment of recalling the time that processing time and time delay is added and obtains and become shock that ball got constantly.Thereby, fixing by advance the summation of processing time and time delay being set for, be for example 1 second, thereby can as percussion figure, extract lighting the image in the moment of recalling 1 second from the end of photographed images.

In addition, from experiment, except the processing time, timing, the error in processing time that doppler sensor 14 starts to detect till ball most also produce based on ball speed, by being multiplied by the coefficient based on ball speed, processing time is revised, thereby can be extracted more accurate shock percussion figure constantly.In the case, the coefficient based on ball speed is different because of the characteristic of the equipment in the structure of Golfing practice device, is suitably set as waiting by experiment the value obtaining.

Utilize the flow chart of Fig. 4, to utilizing the summary of the percussion figure extraction process that the Golfing practice device 10 of present embodiment carries out to describe.In addition, omitted general processing such as the power connection of image extraction process front and back that swings, application program end process.

In each buffer circle, constantly store under the state of photographic images, if player moves ball with golf club striking, doppler sensor 14 detects mobile ball (step S02).

In response to the situation that detects ball, sensor control part 24 start to measure ball speed, bar head speed, flying distance, trajectory, ball after revolve and the various values (step S03) such as sidespin.

If utilize sensor control part 24 to start to measure the various values that comprise ball speed, the processing time timing 24a of portion starts the timing of processing time Ts (step S04).

At Data processing, a plurality of positional informations and the movable information of ball speed determination part 24b based on being input to the ball of sensor control part 24, measures the ball speed (step S05) of getting.Now, because each data are the data of sampling and obtaining with the fixed cycle at the appointed time, therefore, its number because of ball speed different.

Each determination part that comprises ball speed determination part 24b if utilize, the data that sampling is obtained are all processed, and calculate various values, finish to measure (step S06).

Situation about having finished in response to data processing, the timing that the processing time timing 24a of portion carries out finishes, and determines processing time Ts.Then, the value of determined processing time Ts is input to CPU30 (step S07).

At processing time Ts, be threshold value Ta following in the situation that, CPU30 using time delay F as constant B, calculate (step S09).In the present embodiment, as the unit of F time delay, used the time (frame: frame) of a photographed images of storage (1 frame).In addition, about constant B, Ta is same with threshold value, by experiment, is waited and is carried out suitably setting.In addition, in the situation that must revise the processing time based on ball speed because of the characteristic of equipment, without utilizing threshold value Ta to judge, and, also without the processing of step S09.

In the situation that processing time Ts surpasses threshold value Ta, CPU30 utilizes following formula to calculate F time delay (step S10).

F[frame]＝60-a×(Ts/16[msec])

Wherein, a is the coefficient determining based on ball speed, by being multiplied by this coefficient, processing time Ts is revised.Coefficient a and threshold value Ta, constant B are same, are the values of the characteristic based on equipment, by experiment, are waited and are carried out suitably setting.In addition, when according to ball speed coefficient of determination a, by calculating at any time or deciding with reference to the pre-stored suitable methods such as tables of data in suitable memory.

In addition, in the present embodiment, owing to using, in 1 second, clap the equipment of 60 frames, therefore, in calculating the above formula of F time delay, use 60 and 16 such values, but be not limited to this.For example, when using while clapping the equipment of 30 frames in 1 second, replace 60 with 30, with 33, replace 16.

Determining F moment time delay, CPU30 produces triggering signal (step S11).

CPU30 using triggering signal as benchmark constantly, from benchmark constantly through after time delay F, finish the positive renewal storage (step S12) by the new photographed images in buffer circle 27 with buffer circle 26 and the back side.

CPU30 extract positive with buffer circle 26 and the back side with in buffer circle 27, store, amount to the image that swings (step S13) in 4 seconds.Now, due to as mentioned above, based on processing time Ts, decide the time delay F of triggering for generating after the moment, therefore, the image during using shock, as benchmark, extracts the image that swings of first 3 seconds, latter 1 second.That is, can extract from the time series of the integral image that swings the image while clashing into.Then, according to player's operation, the image that will swing is shown on screen 11 as video playback.

In addition, because the image that can take while clashing into extracts the image that swings as benchmark, therefore, for example, player's swing image and other people demonstration can also be swung to image side by side, the demonstration so that the consistent mode of timing during both shocks is reset.

In addition, the present invention is not limited to above-mentioned embodiment, can carry out various distortion.
