Application software responsible for a series of processes for outputting data in cooperation with other communication terminals is installed in advance in each of the smartphone 1 and the smartphone 2. Hereinafter, the application software is referred to as “pair application”. Specifically, the pair application is a function related to pairing between the smartphone 1 and the smartphone 2, a function for transmitting and receiving data between the smartphone 1 and the smartphone 2 after the pairing is established, and the data is output in cooperation Functions related to various adjustments to Details of the processing of the pair application will be described later.

<< flow of processing concerning linked output of data >>
Next, an operation outline of the smartphone according to the present embodiment will be described using FIGS. 2 and 3. (A) to (g) of FIG. 2 show an operation outline of the smartphone 1 and the smartphone 2 according to the present embodiment. Moreover, FIG. 3 has shown the flow of the process in each smart phone 1 and 2 at the time of operating the smart phone 1 as shown to (a)-(g) of FIG.

  In the following, as an example in which the smart phone 1 and the smart phone 2 cooperate to output data using FIG. 2 and FIG. 3, when the smart phone 1 and the smart phone 2 have one image adjacent to each other, An example of displaying so as to be connected will be described. However, the data is not limited to an image, and may be, for example, audio data or moving image data.

  In the smartphone 1, when the user performs an operation for instructing activation of the pair application, such as touching the icon α of the pair application, the smartphone 1 activates the pair application. Similarly, the smartphone 2 activates the pair application according to the instruction operation of the user ((a) in FIG. 2 and S1 in FIG. 3).

  When the pair application starts, the smartphone 1 and the smartphone 2 perform a pairing process by executing a function related to pairing of the pair application (S3 in FIG. 3). At this time, the smartphone 1 and the smartphone 2 may indicate to the user that the device of the communication partner is being searched for ((b) in FIG. 2).

  When the pairing process is completed, that is, pairing between the smartphone 1 and the smartphone 2 is established (YES in S5 of FIG. 3), the smartphone 1 and the smartphone 2 execute the pairing partner confirmation process (S7 of FIG. 3) ).

  Here, the pairing partner confirmation process is one of the processes executed in the pair application, and is performed in the smartphone 1 and the smartphone 2 to make the user of each terminal confirm the partner terminal with which the pairing has been established. Indicates processing. In other words, the pairing party confirmation process is a process for making the user confirm whether or not the terminal (smartphone 1 or smartphone 2) owned by the user is paired with an appropriate partner terminal.

  Specifically, when pairing is established (YES in S5 of FIG. 3), the smartphone 1 and the smartphone 2 display an image of the same color on their respective display screens to allow the user to communicate with the user's own terminal and the other party. It notifies that the terminal has been paired ((c) in FIG. 2). The pairing between the smartphone 1 and the smartphone 2 may be indicated by a method other than the above-described image display.

  Subsequently, the smartphone 1 executes a process for establishing pairing with another terminal. Specifically, the other party terminal identification unit 151 supplied with the changed terminal name starts a search for a terminal having <application name> (S37 in FIG. 5). In the example of FIG. 4, among the terminals in the communicable range (the communicable range of Bluetooth in the smartphone 1), the terminal having the character string of “pair application” in the terminal name is specified.

  The process described above is also executed by the smartphone 2 which is a terminal for which the user is trying to establish pairing with the smartphone 1. That is, the process from step S31 to step S37 described above is also performed in the smartphone 2. More specifically, the terminal name is also changed to “<application name> _ <acquired time>” (for example, “pair application_2014092212010548” illustrated in (d) of FIG. 4) in the smartphone 2 by execution of the pair application. Then, the smartphone 2 (specifically, the other party terminal identification unit 151 of the smartphone 2) identifies a terminal having a character string of “pair application” in the terminal name among the terminals in the communicable range of Bluetooth in the smartphone 2.

  Subsequently, the details of the process of step S39 in FIG. 5 will be described later, and the processes after step S41 will be described. When the terminal having the <application name> is found (YES in S41 of FIG. 5), the other party terminal identification unit 151 of the smartphone 1 refers to the time included in the terminal name for each of the found terminals. Then, it is determined whether the time is newer than the time included in the terminal name of the own terminal (S43 in FIG. 5). If there is a terminal newer than the time included in the terminal name of the own terminal (YES in S43 of FIG. 5), then the other party identification unit 151 determines that the time included in the terminal name of the terminal is within the threshold range. It is determined whether or not (S45 in FIG. 5). Here, the threshold is a numerical value indicating the difference between the time included in the terminal name of the smartphone 1 and the time included in the terminal name of the found terminal (for example, the smartphone 2). This numerical value may be a numerical value that can be determined that the other party's terminal has executed the pair application to establish pairing with the own terminal from now. For example, the specific threshold value may specify a range such as 0 to 1 minute, or may specify an upper limit of the range such as 40 seconds.

  When there is a terminal within the range of the threshold (YES in S45 of FIG. 5), the other terminal identification unit 151 includes, among the terminals, a terminal including the time closest to the time included in the terminal name of the own terminal in the terminal name Are identified (S47 in FIG. 5, terminal identification step). Thereby, the terminal which establishes a pairing with the smart phone 1 is decided to one. For example, as shown in (d) of FIG. 4, a terminal that establishes pairing with the smartphone 1 is determined as the smartphone 2.

  The other party terminal identification unit 151 of the smartphone 1 supplies the terminal name of the identified terminal to the pairing setting unit 152. The pairing setting unit 152 transmits a pairing request for establishing pairing to the terminal indicated by the supplied terminal name (S49 in FIG. 5, communication establishment step). At this time, the pairing setting unit 152 may transmit, to the smartphone 2, the terminal name (changed terminal name) of the smartphone 1, and the image quality mode and the brightness setting in the smartphone 1.

  Then, the flow of the process after step S37 in the smart phone 2 is demonstrated. The smartphone 1 executes the process of step S49, and transmits the pairing request to the smartphone 2.

  When the communication control unit 15 of the smartphone 2 receives a pairing request from another terminal (in this example, the smartphone 1) (YES in step S39 of FIG. 5), the other device identification unit 151 sets that to the pairing setting unit 152 Notice. When the other party terminal identification unit 151 receives the notification, the other party terminal identification unit 151 cancels the search for the terminal having the <application name> (step S61 in FIG. 6). FIGS. 5 and 6 illustrate an example in which the pairing request from the smartphone 1 is received when the smartphone 2 is executing a search for a terminal having an <application name>. This example is an example, and the timing at which the smartphone 2 receives the pairing request and cancels the process being executed is not limited to this example. That is, as long as the other party terminal identification unit 151 of the smartphone 2 does not receive the pairing request (NO in step S39 in FIG. 5), the other party terminal identification unit 151 continues the pairing process (executes the processes in step S41 and later in FIG. 5). Then, if a pairing request is received while performing the processing from step S41 to step S45, the processing performed at that time is canceled.

  Subsequently, the pairing setting unit 152 of the smartphone 2 transmits the pairing permission and information of the own terminal to the terminal (smartphone 1 in this example) that has transmitted the pairing request (S63). Here, the information on the own terminal refers to the terminal name of the smartphone 2 and information such as the image quality mode and the brightness setting in the smartphone 2.

  When the partner terminal identification unit 151 of the smartphone 2 receives the pairing request, it identifies the terminal name (changed terminal name) of the terminal that has transmitted the pairing request, and the terminal having the changed terminal name (in this example) It may be determined whether the smartphone 1) satisfies the conditions of the terminal establishing the pairing. That is, the other party terminal identification unit 151 of the smartphone 2 determines whether the changed terminal name of the terminal that has transmitted the pairing request includes the same application name as the changed terminal name of the own terminal or the time included in the changed terminal name of the own terminal It is determined whether the time information indicating the time older than the time indicated by the information is included or the time indicated by the time information included in the changed terminal name of the terminal that has transmitted the pairing request is within the threshold range. And when it determines with it being a terminal which satisfy | fills these conditions, pairing permission is transmitted.

  When the communication control unit 15 of the smartphone 1 receives the pairing permission transmitted from the smartphone 2, the pairing setting unit 152 establishes the pairing between the smartphone 1 and the smartphone 2. The smartphone 1 and the smartphone 2 store the received information of the other party terminal as the other party terminal information 34 in the RAM 30 of the own terminal.

  On the other hand, when the terminal having the <application name> is not found (NO in S41 of FIG. 5), the time included in the terminal name of the found terminal is older than the time included in the terminal name of the own terminal In the case (NO in S43 of FIG. 5) or the time included in the terminal name is outside the range of the threshold (NO in S45 of FIG. 5), the other party terminal identification unit 151 cancels the pairing process Then, the user is notified of the pairing failure (S51). For example, as shown in (e) of FIG. 4, when the terminal in the communicable range of Bluetooth in the smartphone 1 is only the smartphone 2 that is not executing the pair application (the terminal name is not changed), the smartphone 1 The display unit 22 displays on the display unit 22 that a partner terminal for establishing a pairing can not be found. More specifically, the other party terminal identification unit 151 in the smartphone 1 notifies the application execution unit 12 that the other party terminal that establishes the pairing can not be found. When the application execution unit 12 receives the notification, the application execution unit 12 instructs the display control unit 14 to display an image indicating that the partner terminal can not be found. When the display control unit 14 receives the instruction, the display control unit 14 causes the display unit 22 to display an image (for example, an image shown in (e) of FIG. 4) indicating that the partner terminal can not be found. The notification of the pairing failure to the user is not limited to the display of the image, and may be a notification by voice or a notification by vibration.

Second Embodiment
Another embodiment of the present invention is described below with reference to FIGS. 7 to 9. FIG. 7 is a diagram showing an outline of processing executed by the smartphone 1 and the smartphone 2 according to the present embodiment. Moreover, FIG. 8 is a figure which shows an example of the flow of the pairing process in the smart phone 1 and the smart phone 2 which concern on this embodiment. FIG. 9 is a flow chart showing an example of the process flow of “B” in FIG. In addition, about the member which has the same function as the member demonstrated in the said embodiment for convenience of explanation, the same code | symbol is appended and the description is abbreviate | omitted.

  As described in the first embodiment, the smartphone 1 and the smartphone 2 change the terminal name along with the execution of the pair application. That is, for the user, even if a character string desired by the user is set as the terminal name of the own smartphone, the terminal name is forcibly changed. That is, there is a possibility that the user may be dissatisfied by changing the terminal name he / she desires. In addition, since the terminal name is a character string unfamiliar to the user, the user may be confused.

  Therefore, as illustrated in FIG. 7, when pairing is established, the smartphone 1 and the smartphone 2 according to the present embodiment restore the terminal name of the own terminal. Specifically, while the pairing process is being performed, in order to specify the other party establishing the pairing, as shown in (a) of FIG. It is assumed that "time>". On the other hand, when pairing is established, as shown in (b) of FIG. 7, the terminal name of the own terminal is returned to the original terminal name. In the example of (b) of Drawing 7, smart phone 1 returns a terminal name to A0001, and smart phone 2 returns a terminal name to A0002.

  The pairing process in the present embodiment, in particular, the process of returning the above-described terminal name will be described in more detail with reference to FIGS. 8 and 9. In addition, since the process of step S71-step S89 in FIG. 8 is the same as the process to step S31-step S49 in FIG. 5, description here is abbreviate | omitted.

  The communication control unit 15 of the smartphone 1 that has transmitted the pairing request is in a state of waiting for pairing permission (S91). Here, when the pairing permission is received (YES in S91), the communication control unit 15 notifies the device name changing unit 123 that the pairing permission has been received. The device name change unit 123, upon receiving the notification, restores the terminal name (S93). Specifically, the device name changing unit 123 reads the own terminal information 31 from the RAM 30, and changes the terminal name to a character string (original terminal name) included in the own terminal information 31 as a terminal name. In the example of FIG. 7, the device name change unit 123 returns the terminal name to "A0001".

  Then, the device name changing unit 123 supplies the original terminal name (in this example, “A0001”) to the communication control unit 15 (specifically, the pairing setting unit 152). The pairing setting unit 152 transmits the supplied original terminal name to the smartphone 2.

  On the other hand, when the smartphone 2 receives the pairing request from another terminal (in this example, the smartphone 1), the smartphone 2 cancels the search for the terminal having the <application name> as in the smartphone 2 of the first embodiment ( S101) The pairing permission and the information of the own terminal are transmitted to the terminal (in this example, the smartphone 1) which has transmitted the pairing request (S103). The details of the processes of step S101 and step S103 have already been described in the first embodiment, and thus the description thereof is omitted here.

  Then, the smartphone 2 restores the terminal name (S105). In the example of FIG. 7, the device name change unit 123 returns the terminal name to "A0002". About the detail of this processing, since it is the same as processing of Step S91 to Step S93 in smart phone 1, explanation here is omitted. Finally, the pairing setting unit 152 of the smartphone 2 transmits the supplied original terminal name to the smartphone 1. Thereby, the smart phone 1 and the smart phone 2 can mutually acquire the original terminal name of the other party's terminal.

As described above, when pairing is established, the smartphone 1 and the smartphone 2 according to the present embodiment restore the changed terminal name to the original. This can prevent the user from being dissatisfied or confused.
Third Embodiment
Yet another embodiment of the present invention will be described below with reference to FIG. FIG. 10 is a block diagram showing an example of the main configuration of the smartphone 3 and the smartphone 4 according to the present embodiment. In addition, about the member which has the same function as the member demonstrated in the said embodiment for convenience of explanation, the same code | symbol is appended and the description is abbreviate | omitted.

  In the first embodiment and the second embodiment described above, the terminal name is changed to “<application name> _ <acquired time>” in order to specify a partner terminal that establishes pairing. Then, using the number sequence included in <acquired time>, the other terminal that establishes the pairing is specified. However, the terminal name after the change is not limited to “<application name> _ <acquired time>”, and the information used to specify the partner terminal that establishes the pairing is not limited to the acquired time.

  The control unit 10 of the smartphone 3 according to the present embodiment includes the application execution unit 16 instead of the application execution unit 12, and the application execution unit 16 includes the condition information acquisition unit 126 instead of the time acquisition unit 122. In addition, the RAM 30 of the smartphone 3 newly stores the position information 36, the CPU spec 37, and the radio wave intensity 38.

  The condition information acquisition unit 126 acquires various information used as a condition for specifying a partner terminal that establishes pairing. The condition information acquisition unit 126 according to the present embodiment acquires, in addition to the time information described in the first embodiment, the position information of the smartphone 3, the CPU specification of the smartphone 1, and the current radio wave intensity. Here, the position information of the smartphone 3 may be any information that can distinguish the difference in position between the smartphone 3 and another terminal. For example, when the smartphone 3 and the smartphone 4 establish communication by Wi-Fi via the access point, relative position information as viewed from the access point may be used.

  The condition information acquisition unit 126 supplies the acquired various information to the device name change unit 123. Then, the device name changing unit 123 stores the supplied various information in the RAM 30 together with the device name of the application being executed. The device name changing unit 123 changes the terminal name using the various information supplied. That is, the changed terminal name in the present embodiment includes the application name, time, position information, CPU specifications, and radio wave intensity.

  The other party terminal identification unit 151 according to the present embodiment performs the identification of the other party terminal using the position information, the CPU specification, and the radio wave intensity in addition to the identification of the other party terminal of the pairing using the time included in the changed terminal name. Do. Specifically, the other party terminal identification unit 151 refers to the position information in the changed terminal name, and includes in the terminal name a terminal including position information indicating a position closest to the position indicated by the position information of the own terminal (smartphone 3). Identify. When displaying an image over two smart phones, a user often displays two smart phones side by side as shown in (g) of FIG. 1. That is, the terminal including in the terminal name the position information indicating the position closest to the position indicated by the position information of the smartphone 3 is highly likely to be the partner terminal (smart phone 4) that the user is trying to establish pairing with the smartphone 3 . Therefore, the other party terminal identification unit 151 of the present embodiment performs the identification using the position information as described above, and correctly identifies the other party terminal whose user is trying to establish pairing.

Further, among the terminals including <application name> in the changed terminal name, the other terminal identification unit 151 identifies a terminal whose CPU specification in the changed terminal name is equal to or more than a predetermined threshold. When transmitting data (for example, image data) from one of the two smartphones for which pairing is established to the other smartphone, if the CPU specification of the other smartphone is low, it takes time to transmit the data. . Therefore, the other party terminal identification unit 151 according to the present embodiment performs identification using the CPU specifications as described above, and establishes pairing between smartphones that can realize smooth data transmission and reception.
Further, among the terminals including <application name> in the changed terminal name, the other terminal identification unit 151 identifies a terminal whose radio wave intensity is equal to or higher than a predetermined threshold. Here, the smartphone having high radio wave strength is likely to be a smartphone closer to the own terminal. Therefore, the other party terminal identification unit 151 according to the embodiment performs the identification using the radio wave intensity as described above, and correctly identifies the other party terminal whose user is trying to establish pairing.

  In addition, since each part of the smart phone 4 which concerns on this embodiment is the same as the member which has the same member name in the smart phone 3, and the function is the same, description here is abbreviate | omitted. That is, the smartphone 3 and the smartphone 4 in the present embodiment are two smartphones having the same function. Moreover, it is an example that the smart phone 3 and the smart phone 4 have the same function, and the smart phone 3 and the smart phone 4 may have different functions.

  Moreover, although time, position information, CPU specifications, and radio wave intensity are acquired as various information in the present embodiment, the present invention is not limited to this example. That is, the information to be acquired may be at least one of time, position information, CPU specifications, and radio wave intensity. In addition, the condition information acquisition unit 126 may acquire information other than the information described above.

[Modification]
In the first to third embodiments described above, an example has been described in which the terminal name is changed as an identifier of the terminal in order to establish communication by Bluetooth. However, the identifier of the terminal is not limited to the terminal name. For example, when establishing Wi-Fi communication via an access point, the identifier (SSID) of the access point communicably connected to each terminal may be changed.

  Furthermore, in the first to third embodiments, the first half of the changed terminal name is used as the application name, but it can be seen that smartphones that want to establish communication are common and have functions that they want to realize If it is such, it is not limited to the application name, and may be information (activation information) consisting of at least one of letters, numbers, and symbols. Also, the user may be able to freely set the validation information.

  Further, depending on the terminal, communication may be possible by a plurality of communication methods. Therefore, the first half of the changed terminal name is information indicating whether the application name and each communication method are supported, and the counterpart terminal identification unit 151 is configured to identify a terminal whose first half matches completely. It may be. For example, if a certain terminal can communicate by Bluetooth, can communicate via an access point by Wi-Fi, can communicate without an access point by Wi-Fi, can not communicate by NFC, the first half of the changed terminal name is " It becomes “pair application 1110”.

  Further, as shown in (d) of FIG. 2, the smartphone 1 and the smartphone 2 display on the display unit 22 image candidates to be displayed across both terminals, but the candidates are determined according to preset category information. It may be done. Specifically, the application execution unit 12 sets in advance category information corresponding to the user operation. The category information is, for example, “the latest day” or “photograph of Hokkaido travel on 9/22”, etc. The application execution unit 12 identifies the image data 41 according to the set category information and identified The information indicating the image data 41 is supplied to the display control unit 14. The display control unit 14 causes the display unit 22 to display image candidates based on the supplied information.

  More specifically, the application execution unit 12 specifies the image data 41 corresponding to the set category information by referring to the information on the date and time, the information on the position, and the like added to the image data 41. In addition, the application execution unit 12 may add various information to the image data 41. For example, when the image data 41 which is a plurality of photographs is graphed by taking the shooting date and time on the horizontal axis and the number on the vertical axis, travel is performed for a portion where many photographs are displayed at the same position on the horizontal axis. Can be identified as a photo of If position information can be acquired from the additional information of the photo included in this portion, category information such as “Photo of 9/22 trip to Hokkaido” can be added to the photo included in this portion.

  Also, the resolution of the touch panel 20 and the size of the display area may be transmitted to the other terminal. As a result, since the smartphone 1 can acquire the resolution of the partner terminal (smartphone 2) and the size of the display area, as shown in (e) of FIG. Based on the locus of coordinates, how the smartphone 1 and the smartphone 2 are arranged, more specifically, of the sides forming the rectangular smartphone 1 and the smartphone 2, two smartphones are adjacent to each other It is possible to specify where and from where on the contact side that is in contact.

  That is, when the user performs a drag and drop operation, the touch acquisition unit 11 specifies the touch coordinates on the touch side of the smartphone 1 and the touch coordinates on the touch side of the smartphone 2. In addition, the coordinates of the start point and the coordinates of the end point of the operation are also specified. Then, the application execution unit 12 can specify the direction of the operation from these coordinates. In addition, if application executing unit 12 uses the resolution of the own device and the size of the display area, the resolution of the other party terminal and the size of the display area, and the specified touch coordinates and the direction of operation, In other words, it is possible to specify what shape the connected display area consisting of the display areas of the two smartphones will be. Then, the application execution unit 12 of the smartphone 1 displays the portion of the image data 41 to be displayed in the display area of the smartphone 1 according to the positional relationship (the shape of the connected display area) between the identified smartphone 1 and the smartphone 2 And a portion to be displayed in the display area of the smartphone 2 are specified.

  Thereby, even in the case where the smartphone 1 and the smartphone 2 are arranged in a shifted manner (in the contact side, there is a portion not in contact with the other terminal), the image data 41 displayed across the two smartphones is It becomes possible to display without deviation. For example, even if the sizes of the display areas of the smartphone 1 and the smartphone 2 are different, the image data 41 displayed across the two smartphones can be displayed without a gap.

[Example of software implementation]
Control blocks of the smartphones 1 to 4 (in particular, the touch acquisition unit 11, the application execution unit 12, the display control unit 14, the communication control unit 15, and the application execution unit 16) are logic circuits (IC chip) or the like. It may be realized by hardware) or may be realized by software using a CPU (Central Processing Unit).

  In the latter case, the smartphones 1 to 4 are a CPU that executes instructions of a program that is software that realizes each function, and a ROM (Read Only Memory) in which the program and various data are readably recorded by a computer (or CPU). Alternatively, a storage device (these are referred to as “recording media”), a RAM (Random Access Memory) for developing the program, and the like are provided. The object of the present invention is achieved by the computer (or CPU) reading the program from the recording medium and executing the program. As the recording medium, a “non-transitory tangible medium”, for example, a tape, a disk, a card, a semiconductor memory, a programmable logic circuit or the like can be used. The program may be supplied to the computer via any transmission medium (communication network, broadcast wave, etc.) capable of transmitting the program. The present invention can also be realized in the form of a data signal embedded in a carrier wave, in which the program is embodied by electronic transmission.
