(Imaging apparatus 100, 200)
The imaging devices 100 and 200 are, for example, digital cameras, and may be the same digital camera or different digital cameras. In this embodiment, since the basic configurations of the imaging devices 100 and 200 are the same, the configuration of the imaging device 100 will be described, and the description of the configuration of the imaging device 200 will be omitted.

  The imaging apparatus 100 includes a communication unit 101, a GPS module 102, an imaging unit 103, and a CPU 104.

  The communication unit 101 communicates with the communication unit 26 of the communication module 20. The communication unit 101 receives a shooting request from the communication module 20. In addition, the communication unit 101 transmits the position of the imaging device 100, the specification of the imaging device 100, and the like to the communication module 20. The communication unit 101 can also communicate with the communication unit 301 of the personal computer 300 described later, and the communication unit 101 transmits an image captured by the imaging unit 103 to the personal computer 300.

  The GPS module 102 is a position detection device that detects the position of the imaging device 100, and the position of the imaging device 100 is transmitted to the communication module 20 by the communication unit 101 as described above.

  The imaging unit 103 includes a plurality of lenses and imaging elements such as a CCD (Charge Coupled Device) image sensor and a CMOS (Complementary Metal Oxide Semiconductor) sensor, and performs imaging of moving images and still images. is there.

  The CPU 104 controls the entire imaging apparatus 100. In the present embodiment, the CPU 104 controls the timing (such as the start of imaging or the end of imaging) of capturing a user according to an instruction from the communication module 20.

(PC 300)
The personal computer 300 includes a communication unit 301, a memory 302, and a CPU 303.

  The communication unit 301 communicates with the communication unit 26 of the communication module 20 and receives various data from the communication module 20. In addition, the communication unit 301 receives image data captured by the imaging devices 100 and 200.

  The memory 302 is a non-volatile memory and stores various data received from the communication module 20 and the imaging devices 100 and 200. Note that the memory 302 stores the image DB shown in FIG. Details of the image DB will be described later.

  The CPU 303 controls the entire personal computer 300. In the present embodiment, the user's history (for example, baseball practice time recording) and the like are recorded based on various data received from the communication module 20 and the imaging devices 100 and 200. , Progress (for example, the speed of the swing has increased) and comparison with professionals and the like (comparison of forms, comparison of various speeds (swing speed, etc.)).

  Next, processing of the electronic device system 1 configured as described above will be described with reference to FIG.

  FIG. 6 is a flowchart regarding data collection processing performed under the control of the CPU 27. The processing in FIG. 6 is assumed to be triggered by the user wearing a shoe (spike) 52 provided with the electrode unit 21.

  In the process of FIG. 6, first, in step S10, the CPU 27 acquires the output of the GPS module 23a and detects the position of the user.

  Next, in step S12, the CPU 27 determines whether the user is at a predetermined location based on the output of the GPS module 23a. Here, it is assumed that the predetermined place is a baseball field or practice ground set in advance by a user or the like. It is assumed that the predetermined place is stored in the practice place table shown in FIG. In FIG. 3A, the positions of the four corners when the practice place is regarded as a rectangular area are defined by latitude and longitude. In step S12, when the output of the GPS module 23a is included in any of the practice locations 1, 2,... Stored in the practice location table, the determination is affirmed and the process proceeds to step S14. If the determination in step S12 is negative, the process returns to step S10.

  In step S14, the CPU 27 determines whether or not there is a predetermined output from the acceleration sensor 23b. This step S14 is a step for detecting the practice start time of the user. In any of the sports, since the exercise starts from the preparatory gymnastics and the running before the practice using the tools, in the present embodiment, the CPU 27 determines when the acceleration sensor 23b detects an acceleration different from the normal walking. Is determined to have been output. It is assumed that acceleration in normal walking is set in advance. Therefore, for example, when a walking user starts running, the determination in step S14 is affirmed, and the process proceeds to step S16.

  In step S <b> 16, the CPU 27 obtains date and time (time) information when the user started a preparatory exercise such as running from the time measuring unit 24. This step S16 is a step for keeping a record of the practice time of the user. The date / time (time) information acquired in step S16 is input to the start date / time field of the practice time DB of FIG. 3B stored in the flash memory 25. In addition, when inputting to the start date / time column of the practice time DB, a serial number or the like is input to the practice ID column.

  As described above, according to the electronic device system 1 (communication module 20) of the present embodiment, the practice start is automatically recognized and the practice time is automatically measured by the action of the user wearing the shoes 52 and starting the running. In order to start, it is not necessary for the user to perform a special operation for recording the practice time.

  Next, in step S <b> 18, the CPU 27 determines whether or not human body communication is established between the electrode portion 21 provided on the shoe (spike) 52 and the electrode portion 15 provided on the bat 50. In this case, human body communication is established between the electrode portions 21 and 15 when the user grips the bat 50 after performing the preparatory exercise. Therefore, when the user holds the bat 50, the determination in step S18 is affirmed, and the process proceeds to step S20.

  In step S <b> 20, the CPU 27 requests the communication device 10 provided in the bat 50 to transmit information, and acquires information on the user's position from the GPS module 23 a. The information that the CPU 27 requests to transmit in step S20 includes information on the type of bat (ID or data such as length, weight, and material) stored in the memory 14. In the communication device 10, the CPU 17 transmits information on the type of bat via the transmission unit 16.

  Next, in step S22, the CPU 27 issues a shooting request to the imaging devices 100 and 200 based on the user position information detected in step S20.

  For example, when the imaging devices 100 and 200 are fixed-point cameras, the CPU 27 transmits a shooting request to the imaging device that can best shoot the user according to the position of the user, or one imaging device 100. The user is requested to shoot from the front, and the other imaging device 200 is requested to shoot the user from the side or the back.

  Further, when requesting a photographer to take a picture, the CPU 27 may inform the cameraman's imaging devices 100 and 200 of the position of the user. As a means for contacting the photographer, a mobile phone (such as a telephone function or a mail function) owned by the photographer may be used.

  Next, in step S <b> 24, the CPU 27 determines whether there is a predetermined output from the acceleration sensor 11 and the gyro sensor 12. This step S24 is a step for detecting whether or not the user has started swinging the bat 50. The predetermined output refers to an acceleration value that can be determined that the user is swinging the bat 50, an angular velocity, or the like. Is the value of These values may be obtained by experiment, may be obtained by analyzing a swing image, or may be set for each type of bat. Information for determining the predetermined output of each sensor is defined in, for example, the swing determination table shown in FIG.

  Note that the CPU 17 of the communication device 10 outputs the outputs of the acceleration sensor 11 and the gyro sensor 12 from the time when a predetermined output is received from the acceleration sensor 11 and the gyro sensor 12 after the human body communication with the communication module 20 is established. 20 may be transmitted. Instead of this, after the human body communication with the communication device 10 is established, the communication module 20 causes the acceleration sensor 11 and the gyroscope to communicate with the communication device 10 every predetermined interval (for example, several tens of microseconds to several seconds). The output of the sensor 12 may be requested to be transmitted.

  Note that the order of step S22 and step S24 described above may be interchanged. In this case, after detecting the swing of the bat 50 by the user, an imaging request is made to the imaging devices 100 and 200.

  When the determination in step S24 is affirmed, the process proceeds to step S26, and the CPU 27 acquires the time at which the user starts swinging the bat 50 via the timer unit 24. The CPU 27 can measure the time during which the user swings the bat (batting practice time) by acquiring the time when the user starts swinging the bat 50. In addition, the CPU 27 can measure the batting occupying the entire practice time. The percentage of practice time can also be calculated. The time acquired in step S24 is input into the swing start date / time column of the swing practice time DB shown in FIG. As described above, according to the electronic device system 1 (communication module 20) of the present embodiment, the user automatically recognizes the batting practice and automatically starts the batting practice time measurement by the act of starting the swing. be able to. At the time of the input, the CPU 27 uses the same character string input in the practice ID column of the practice time DB (see FIG. 3B) in step S16 as the practice ID of the swing practice time DB. Enter in the field.

  Next, in step S28, the CPU 27 collects various data and records the collected data in the flash memory 25 (records in the practice data DB in FIG. 5). In this case, the CPU 27 performs recording according to the usage (attribute) of the tool used by the user. In the present embodiment, since the user uses the bat 50, the CPU 27 receives the outputs of the acceleration sensor 11 and the gyro sensor 12 and the output of the biosensor 13 that the CPU 17 transmits via the transmission unit 16. 22, acceleration (detection value of acceleration sensor 11), angular velocity (detection value of gyro sensor 12), biological information (detection value of biological sensor 13), and number of swings when the user is swinging Etc. are recorded in the practice data DB. Further, the CPU 27 collects acceleration information (detected values of the acceleration sensor 23b) related to the movement of the foot when the user is swinging from the acceleration sensor 23b. The data detected in step S24 may be used for collecting these data. In addition, it is not limited to the case where each swing data is recorded as shown in FIG. 5, but the maximum acceleration and average acceleration, the maximum angular velocity and the average angular velocity, the maximum acceleration and the average acceleration relating to the movement of the foot, etc. in the practice data DB. It is good also as recording on. Further, the number of times the target acceleration is cleared may be recorded. The CPU 27 may record the detection value of the biological sensor 13 (for example, raw data of the heart rate) as it is regarding the recording of the biological information, and determine the state of the user from the detection value of the biological sensor 13 (usually, tension, The determined state may be recorded after relaxation or relaxation. Further, the CPU 27 may record the detection values of the GPS module 23a and the azimuth sensor 23c in the practice data DB of FIG. As a result, it is possible to analyze the practice data in consideration of the user's position and the orientation that the user is facing.

  The CPU 27 may record the collected data in the memory 302 of the personal computer 300 together with or instead of the flash memory 25.

  As shown in FIG. 5, the CPU 27 records swing data in the practice data DB in association with the type of tool (the weight and length of the bat). By doing so, it is possible to record in the practice data DB including the attribute of which tool was used and how. Further, as shown in FIG. 5, the CPU 27 counts the number of swings for each practice ID in the practice data DB. In this way, it is possible to compare the number of swings and the degree of progress in each practice.

  Next, in step S30 of FIG. 6, the CPU 27 determines whether or not the human body communication between the communication module 20 and the communication device 10 has been interrupted for a predetermined time. This step S30 is a step for confirming whether or not the user continues the practice of performing the swing of the bat 50 (batting practice). That is, when the human body communication is interrupted for a predetermined time (for example, about several minutes), the CPU 27 can determine that the user has finished the batting practice. Note that the predetermined time can be set for each user. Instead of the above-described method, the CPU 27 establishes human body communication with the communication device 10 provided in another tool (for example, a globe), or the user starts moving from the output of the GPS module 23a or the direction sensor 23c. The user may determine that the user has finished batting practice.

  While the determination in step S30 is negative, that is, while the human body communication is not interrupted for a predetermined time, the CPU 27 returns to step S26 and repeats the processes in steps S26 and S28 to collect time information and various data. continue.

  On the other hand, if the determination in step S30 is affirmative, that is, if the human body communication is interrupted for a predetermined time, the CPU 27 checks the time via the time measuring unit 24 in step S32. Then, the CPU 27 calculates the batting practice time from the confirmed time, and stores it in the swing practice time DB of the flash memory 25 (the practice time column in FIG. 3C). As described above, according to the electronic device system 1 (communication module 20) of the present embodiment, when the human body communication is interrupted for a predetermined time, the end of the batting practice is automatically recognized and the measurement of the batting practice time is automatically finished. can do.

  In step S <b> 32, the CPU 27 issues a photographing end request to the imaging devices 100 and 200. When the imaging devices 100 and 200 are fixed point cameras and the imaging devices 100 and 200 capture a moving image, it is possible to efficiently capture a moving image by transmitting a shooting start request and an end request. . This is particularly effective when, for example, capturing each user's at-bat at the game with a moving image.

  Next, in step S34, the CPU 27 determines whether or not the user is wearing a spike. If the user wears the spike, the CPU 27 returns to step S18 as performing another practice. However, if the user takes off the spike, the CPU 27 acquires time information via the time measuring unit 24 in step S36, and flashes. After recording in the memory 25 (the end time column and the practice time column in the practice time DB (see FIG. 3B)), the entire process of FIG. In addition, when acquiring the exercise end time information in step S36, the CPU 27 may set the time at which the spike is removed as the end time, and finally the predetermined output (walking and walking) from the acceleration sensor 23b before the spike is removed. May be the end time.

  When it is necessary to set a predetermined time when determining whether or not the user is wearing a spike in step S34, a shorter time is set than the predetermined time set in step S30. do it. Further, the CPU 27 may determine whether or not to return to step S18 taking into account whether or not the user is at the practice ground. Prior to step S30, the process of step S34 may be executed, or the process of step S34 may be executed before and after step S30. It should be noted that the determination of whether or not the spike is worn is always performed separately from FIG. 6, and if the determination is denied, the processing of FIG. 6 may be forcibly terminated.

  As described above, according to the electronic device system 1 (communication module 20) of the present embodiment, the end of the practice is automatically recognized and the measurement of the batting practice time is automatically performed with the user taking off the spike as a trigger. Since the process can be terminated, it is not necessary to force the user to perform a special operation.

  Next, the data comparison process of the present embodiment under the control of the CPU 303 will be described with reference to the flowchart of FIG. This data comparison process is a process of comparing data between a target advanced user (for example, an advanced student or a professional) and a user. In the following description, it is assumed that the data (practice data DB) collected by the processing of FIG. 6 is transferred from the communication module 20 to the memory 302 of the personal computer 300.

  In step S50 of FIG. 7, the CPU 303 reads out master data targeted by the user. In this case, data selected by the user is read out as master data from the data of a plurality of players (for example, advanced students) collected using the flowchart of FIG. 6 (that is, data stored in the memory 302). It is also possible to select from the above. Alternatively, target numerical values (swing speed, acceleration, etc.) previously input by the user or the like to the personal computer 300 may be read from the memory 302. Alternatively, professional player data may be stored in the memory 302 in advance, and the CPU 303 may read the professional player data.

  Next, in step S52, the CPU 303 reads out user data. In the present embodiment, the user data collected in the flowchart of FIG.

  Next, in step S54, the CPU 303 compares the master data with the user data. In this case, the CPU 303 can compare the time series change (transition) of the user data with respect to the master data to compare whether the user data is approaching the master data. For example, as shown in FIG. 8, it is possible to compare professional swing data with user swing data (for example, swing speed (maximum value) for each date).

  Next, in step S56, the CPU 303 displays the comparison result in step S54 (FIG. 8) on a display (not shown) of the personal computer 300, notifies the user of the comparison result, and ends the entire process in FIG. In step S56, as shown in FIG. 8, the CPU 303 may also display (notify) the transition of the user's practice amount (such as the number of swings and practice time).

  FIG. 8 is an example. That is, the CPU 303 can perform various analyzes based on the practice data DB of FIG. 5 and notify the user. For example, when it is possible to determine from a user input information whether a certain practice ID is a practice or a game, a difference in swing between a practice and a game or a mental state (a state based on a detection value of the biosensor 13) ) Can be determined and notified to the user. In the flowchart of FIG. 7, the master data and the user data are compared. Instead, a practice amount is set by the personal computer 300, and the set practice amount is compared with the user data. Also good.

  If the data collected from each user is collected and managed in the personal computer 300, the director and coach will be practicing each user's practice (for example, a lot of batting practice time and other practice time). It is also possible to recognize a user (player) who is particularly tense or mentally unstable during a game, and helps to set the practice amount, practice order, practice method, and the like.

  As described above in detail, according to the present embodiment, the electrode unit 21 of the communication module 20 contacts or faces the user's foot, and the electrode unit 15 of the communication device 10 contacts or faces the user's hand. When communication between the communication module 20 and the communication device 10 via the human body becomes possible in the state, the CPU 27 records the flash memory 25 (practice) according to the attribute of the member (bat 50) provided with the communication device 10. Data DB). As a result, in this embodiment, when human body communication becomes possible, it is possible to record records (such as the number of swings and swing speed) according to the member attributes. Recording according to the attribute of the member at a proper timing becomes possible. Thereby, an easy-to-use electronic device system can be provided.

  In the present embodiment, the CPU 27 performs recording (acceleration and speed) according to the attributes of the shoes (spikes) in the flash memory 25 (practice data DB), so that the practice situation can be recorded from various viewpoints. it can.

  Further, in this embodiment, the CPU 27 records the biological information of the human body in the flash memory 25 (practice data DB), so that it can be recorded from various viewpoints such as the status of practice and the difference in mental state between practice and game. .

  In this embodiment, the CPU 27 also records the type of member (bat type) in the flash memory 25 (practice data DB), so it is possible to record which tool (bat) is used and how.

  Further, since the CPU 27 records the time during which human body communication is performed in the flash memory 25 (swing practice time DB), it is possible to record the time during which the swing practice using the bat is performed.

  Further, the CPU 27 ends the recording according to the attribute of the tool (bat) when the electrode unit 15 is not in contact with or facing the hand for a predetermined time (when the human body communication is not performed for the predetermined time). This is done (S30: Yes), so it becomes possible to finish recording the practice data at an appropriate timing with a high probability that the practice using the bat is interrupted or stopped.

  Moreover, CPU27 complete | finishes a recording, when the electrode part 21 and a leg no longer contact or oppose (when the spike 52 is taken off) (S34: When negative), inputs an end date in practice time DB. Therefore, the recording can be terminated (inputting the end date and time to the practice time DB) at an appropriate timing with high probability of having completed the practice.

  In the present embodiment, the communication module 20 includes a communication unit 26 that is different from a communication unit (including the electrode unit 21 and the CPU 27) that performs human body communication. Accordingly, the communication unit 26 can perform communication based on the data received from the communication device 10 and the reception timing in the reception unit 22 of the communication module 20 by human body communication. In the present embodiment, the communication unit 26 communicates with the imaging devices 100 and 200 when the human body communication via the electrode units 15 and 21 becomes possible. Therefore, an appropriate timing such as the timing when the swing exercise is started. Thus, it is possible to make a shooting request to the imaging devices 100 and 200.

  In the present embodiment, the CPU 27 can request the imaging devices 100 and 200 to perform imaging according to the position detected by the GPS module 23a. As a result, it is possible to request the imaging devices 100 and 200 to perform appropriate shooting by the user.

  In addition, since the CPU 27 requests the imaging devices 100 and 200 to finish shooting when the bat is not in contact with or facing the user's hand for a predetermined time (S32), the user performs swing exercise. Shooting can be terminated at an appropriate timing with a high probability of termination.

  In this embodiment, a physical quantity sensor (acceleration sensor 11 and gyro sensor 12) that detects a physical quantity (acceleration or angular velocity) acting on the bat in accordance with the user's operation is provided in the bat 50, and the CPU 17 and the transmission unit 16 communicates the physical quantity detected by the physical quantity sensor with a device (communication module 20) different from the bat 50 via the electrode part 15 that contacts or faces the human body and the human body. Thereby, the physical quantity which acts on the bat 50 with respect to the communication module 20 can be transmitted to the communication module 20 by the human body communication at an appropriate timing when the user performs a swing exercise or the like with the bat. Also from this point, it is possible to provide an electronic device system 1 that is easy to use.

  Further, in the present embodiment, since the biosensor 13 is provided in the vicinity of the electrode unit 15, the biometric information detected by the biosensor 13 together with the physical quantity acting on the bat 50 according to the user's operation is also at an appropriate timing. Thus, it can be transmitted to the communication module 20.

  In the present embodiment, since the CPU 17 starts detection by the acceleration sensor 11 and the gyro sensor 12 after the human body communication is established, the detection timing by each sensor can be set to an appropriate timing. Thereby, the power consumption of each sensor can be reduced.

  In the above-described embodiment, the case where shooting is performed by the imaging devices 100 and 200 during the swing exercise has been described. However, the present invention is not limited to this, and all the exercises may be shot by the imaging devices 100 and 200. In this case, the CPU 27 may perform step S22 in FIG. 6 immediately after step S16, and perform the photographing end request in step S32 immediately after step S34.

In this case, the comparison result may be displayed on the screen (display unit) of the mobile terminal. When information for identifying a user is stored in the mobile terminal, the above-described identification of the user using the personal computer 300 can be omitted. Also, by inputting the order and amount of practice from the input unit of the mobile terminal, it is possible to compare the scheduled practice with the practice actually performed. In this case, the comparison result may be displayed on the screen of the mobile terminal. Further, when the planned practice amount is performed, the user may be notified using the vibration function of the mobile terminal or the like. Note that the order and amount of practice may be communicated from the personal computer 300 to the communication module 20 and stored in the flash memory 25.

However, the present invention is not limited to this, and the CPU 27 starts the swing practice. At a stage, the personal computer 300 may be requested to record practice data.

  Moreover, although the said embodiment demonstrated the case where practice data was recorded only when a user exists in a specific place in FIG.6 S12, it is not restricted to this. For example, steps S10 and S12 in the process of FIG. 6 may be omitted, and the process of FIG. 6 may be started from step S14. In the process of FIG. 6, the process of steps S14 and S16 is performed in consideration of the preparatory exercise and the like, but not limited to this, for example, steps S14 and S16 of the process of FIG. It is good also as starting the process of FIG. 6 from step S18. In this case, steps S34 and S36 may be omitted.
