In addition, below, the case where the communication terminal which concerns on this invention is implement | achieved with a smart phone (the smart phone 1 and the smart phone 2) as an example is demonstrated. However, the communication terminal according to the present invention is not limited to a smartphone, and can be applied to any electronic device capable of data communication with other communication terminals such as a personal computer (PC) and a tablet PC.

≪Smartphone functions≫
First, the smartphone 1 and the smartphone 2 according to the present embodiment will be outlined. The smartphone 1 and the smartphone 2 are communication terminals that pair with a terminal other than their own terminal and output data in cooperation with a pairing partner terminal. In the present embodiment, “pairing” means that the smartphone 1 or the smartphone 2 and another communication terminal identify and link each other in order to perform one-to-one communication.

In the following description, unless otherwise specified, the smartphone 1 and the smartphone 2 perform pairing and perform data output in cooperation. However, the smartphone 1 and the smartphone 2 may be paired with an electronic device other than the smartphone and perform data output in cooperation.

In the following description, the smartphone 1 and the smartphone 2 are described as performing communication using Bluetooth (registered trademark), but the communication method of the smartphone 1 and the smartphone 2 is not limited to this example. For example, the smartphone 1 and the smartphone 2 may perform communication by Wi-Fi (registered trademark), or may perform communication by short-range wireless communication (NFC, Near Field Communication). Hereinafter, when “communication” is simply written without particularly indicating a communication method, communication by Bluetooth is indicated. A plurality of smartphones 2 to be paired may exist.

≪Pair app≫
Each of the smartphone 1 and the smartphone 2 is preinstalled with application software responsible for a series of processes for outputting data in cooperation with other communication terminals. Hereinafter, the application software is referred to as “pair application”. Specifically, the pair application is a function related to pairing of the smartphone 1 and the smartphone 2, a function for transmitting / receiving data between the smartphone 1 and the smartphone 2 after the pairing is established, and outputting the data in cooperation with each other It has functions related to various adjustments. Details of the processing performed by the pair application will be described later.

≪Process flow related to linked output of data≫
Next, the operation | movement outline | summary of the smart phone which concerns on this embodiment is demonstrated using FIG. 2 and FIG. (A) to (g) of FIG. 2 show an outline of operations of the smartphone 1 and the smartphone 2 according to the present embodiment. FIG. 3 shows the flow of processing in each of the

smartphones

1 and 2 when the smartphone 1 is operated as shown in (a) to (g) of FIG.

In the following, as an example in which the smartphone 1 and the smartphone 2 output data in cooperation with each other using FIG. 2 and FIG. 3, the smartphone 1 and the smartphone 2 display one image, and the respective terminals are adjacent to each other. An example of displaying so as to be connected will be described. However, the data is not limited to images, and may be audio data or moving image data, for example.

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

When the pair application is activated, 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 they are searching for a communication partner device ((b) of FIG. 2).

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

Here, the pairing partner confirmation process is one of processes executed in the pair application, and is performed in the smartphone 1 and the smartphone 2 in order to make the user of each terminal confirm the partner terminal with which pairing has been established. Indicates processing. In other words, the pairing partner confirmation process is a process for allowing the user to confirm whether the terminal (smart phone 1 or smartphone 2) that the user owns is paired with an appropriate partner terminal.

Specifically, when the pairing is established between the smartphone 1 and the smartphone 2 (YES in S5 in FIG. 3), an image of the same color is displayed on each display screen, so that the user can communicate with the terminal and the communication partner. It is notified that the terminal is paired ((c) in FIG. 2). In addition, you may show that the smart phone 1 and the smart phone 2 paired by methods other than the image display mentioned above.

Then, the smartphone 1 and the smartphone 2 allow the user of each terminal to input a confirmation result as to whether or not the pairing partner terminal is appropriate. Specifically, for example, as shown in FIG. 2C, when the pairing is appropriate and data communication is permitted, a “connection OK” button is displayed. When the pairing is inappropriate, “cancel” is displayed. Touch the button.

In the smart phone 1 and the smart phone 2, when the “connection OK” button is pressed, that is, when the user permits data transfer (S9 in FIG. 3), the smart phone 1 and the smart phone 2 next to the user of each terminal, Images to be displayed on both terminals are selected (S11 in FIG. 3). Note that the smartphone 1 and the smartphone 2 are desirably arranged side by side as shown in the drawing because of the subsequent input operations.

More specifically, for example, the user of the smartphone 1 selects the image by touching the smartphone 1 with a desired image for a predetermined time or longer (long-pressing touch) ((d) in FIG. 2).

Hereinafter, an example in which an image is selected in the smartphone 1 and data is transferred from the smartphone 1 to the smartphone 2 will be described. However, an image may be selected in the smartphone 2 and data may be transferred from the smartphone 2 to the smartphone 1. . In this case, the smartphone 2 may perform the same operation as the smartphone 1 described below.

When an image (image β) is selected on the smartphone 1, the smartphone 1 and the smartphone 2 start data transfer processing (S13 in FIG. 3). Here, the data transfer process is one of the processes executed in the pair application, and the data related to the selected image β and the data of the image β are stored in a terminal (smartphone in the figure). The process of transmitting from 1) to the transfer destination terminal (smart phone 2 in the figure) is shown.

In the data transfer process, data related to the image β is transmitted before the image β itself, and then the data of the image β itself is transmitted. Hereinafter, data relating to the selected image transmitted in advance is referred to as “preceding data”. The data of the selected image itself is referred to as “actual data”. Details of the preceding data and the actual data will be described later.

The smartphone 1 displays the preceding data in cooperation with the own terminal and the smartphone 2 at least when an operation (start operation) indicating the start of data display is performed on the own terminal after the start of the data transfer process. Even when the smartphone 1 receives a start operation after the data transfer process is completed, the smartphone 1 may first display the preceding data in cooperation with the smartphone 2 and then display the actual data.

For example, as shown in FIG. 2D, the smartphone 1 slides the finger touched while the user continues to press and hold (touched) so as to straddle the smartphone 1 and the smartphone 2. When the finger is released (the image β is selected and dragged and dropped) ((e) in FIG. 2), the operation is recognized as a start operation.

Then, the smartphone 1 receives the start operation and displays the preceding data of the image β in cooperation with the display screens of the smartphone 1 and the smartphone 2. Specifically, for example, when the preceding data is a thumbnail image of the image β, the smartphone 1 cooperates with the smartphone 2 so that the images are connected on the display screens of the smartphone 1 and the smartphone 2 (so as to be continuous images). Then, the thumbnail image β1 of the image β is displayed ((f) in FIG. 2).

More preferably, the smartphone 1 acquires the time when the touching finger leaves the input surface of the smartphone 1 and the time when the finger touches the end of the input surface of the smartphone 2 to obtain these times. By specifying the adjacent relationship between the smartphone 1 and the smartphone 2 (in which direction the smartphone 2 is positioned when viewed from the smartphone 1), the preceding data of the image β is displayed according to the adjacent relationship. It is desirable to do.

Furthermore, when the data transfer process is completed, the smartphone 1 and the smartphone 2 cooperate with each other to display the actual data β2 of the image β so that the images are connected on the display screens of the smartphone 1 and the smartphone 2 ((g) in FIG. 2). ).

In summary, the smartphone 1 and the smartphone 2 perform pairing with each other ((a) to (b) in FIG. 2) and allow the user to confirm whether the pairing is appropriate ((c) in FIG. 2). . Thereafter, the smartphone 1 transfers the image data selected by one of the terminals to the other terminal ((d) to (e) in FIG. 2).

At this time, the smartphone 1 (or the smartphone 2) can display the preceding data of the image in cooperation during the transfer, and can display the actual data in cooperation after the transfer of the actual data is completed (see FIG. 2 (f) to (g)).

In addition, when the pairing process has failed in the smartphone 1 or the smartphone 2, that is, the pairing has not been established (NO in S5 in FIG. 3), the smartphone 1 and the smartphone 2 notify the user that the pairing has failed. (S17 in FIG. 3). And the smart phone 1 and the smart phone 2 perform a pairing process again (S3 of FIG. 3).

Moreover, when at least one of the users of the smartphone 1 and the smartphone 2 does not permit data transfer between the smartphone 1 and the smartphone 2 (S9 in FIG. 3), the smartphone 1 and the smartphone 2 cancel each other's pairing ( 3 (S19 in FIG. 3), the user is notified that the pairing has failed (S17 in FIG. 3), and a pairing process is performed in order to try to pair with another terminal again (S3 in FIG. 3).

As described above, the first half of the changed terminal name (changed terminal name) is the name of the application executed to validate the Bluetooth setting. The second half is a time after the predetermined time after the pair application is activated (the time acquired by the time acquisition unit 122). The time shown in FIG. 4C includes year, month, day, hour, minute, second, and millisecond, but is not limited to this. For example, it may include from the time to milliseconds without including the month and day. The device name changing unit 123 supplies the changed terminal name to the communication control unit 15.

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

The processing described above is also executed on the smartphone 2 which is a terminal for which the user is trying to establish pairing with the smartphone 1. That is, the above-described processing from step S31 to step S37 is also executed on the smartphone 2. More specifically, in the smartphone 2, the terminal name is changed to “<application name> _ <acquired time>” (for example, “pair application_2014092212010548” shown in FIG. 4D) by executing the pair application. Then, the smartphone 2 (specifically, the partner terminal specifying unit 151 of the smartphone 2) specifies a terminal having the character string “pair application” in the terminal name among terminals in the Bluetooth communicable range of the smartphone 2.

Subsequently, details of the processing in step S39 in FIG. 5 will be described later, and the processing after step S41 will be described. When the terminal having <application name> is found (YES in S41 in FIG. 5), the counterpart terminal specifying unit 151 of the smartphone 1 refers to the time included in the terminal name for each found terminal. Then, it is determined whether or not the time is newer than the time included in the terminal name of the terminal (S43 in FIG. 5). If there is a terminal that is newer than the time included in the terminal name of the terminal itself (YES in S43 in FIG. 5), then the partner terminal specifying unit 151 has the time included in the terminal name of the terminal within the threshold range. Is determined (S45 in FIG. 5). Here, the threshold is a numerical value indicating a 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 partner terminal has executed the pair application in order to establish pairing with the terminal from now on. For example, a specific threshold value may be a range that specifies 0 to 1 minute, for example, or an upper limit of the range such as 40 seconds.

When there is a terminal within the threshold range (YES in S45 of FIG. 5), the counterpart terminal specifying unit 151 includes a terminal that includes the time closest to the time included in the terminal name of the terminal in the terminal name. (S47 in FIG. 5, terminal specifying step). Thereby, the terminal which establishes pairing with the smart phone 1 is decided to be one. For example, as illustrated in FIG. 4D, the terminal that establishes pairing with the smartphone 1 is determined as the smartphone 2.

The partner 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 brightness settings of the smartphone 1.

Subsequently, the flow of processing after step S37 in the smartphone 2 will be described. In addition, the smart phone 1 shall perform the process of step S49 and shall transmit the pairing request | requirement with respect to the smart phone 2. FIG.

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 in FIG. 5), the communication control unit 15 notifies the partner terminal identification unit 151 pairing setting unit 152 to that effect. Notice. Upon receiving the notification, partner terminal specifying unit 151 cancels the search for the terminal having <application name> (step S61 in FIG. 6). 5 and 6 illustrate an example of receiving a pairing request from the smartphone 1 when the smartphone 2 is searching for a terminal having <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, unless the pairing request is received (NO in step S39 in FIG. 5), the counterpart terminal specifying unit 151 of the smartphone 2 continues the pairing process (executes the processes after step S41 in FIG. 5). If a pairing request is received while the processing from step S41 to step S45 is being executed, the processing being performed at that time is cancelled.

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

In addition, when receiving the pairing request, the counterpart terminal specifying unit 151 of the smartphone 2 specifies 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 for establishing pairing. That is, the partner terminal specifying unit 151 of the smartphone 2 includes the change terminal name of the terminal that has transmitted the pairing request, including the same application name as the change terminal name of the own terminal, or the time included in the change terminal name of the own terminal. It is determined whether time information indicating a time older than the time indicated by the information is included, or whether the time indicated by the time information included in the changed terminal name of the terminal that has transmitted the pairing request is within a threshold range. When it is determined that the terminal satisfies these conditions, a pairing permission is transmitted.

Then, 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 pairing between the smartphone 1 and the smartphone 2. The smartphone 1 and the smartphone 2 store the received partner terminal information as partner terminal information 34 in the RAM 30 of the terminal itself.

On the other hand, when a terminal having <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 when the time included in the terminal name is outside the threshold range (NO in S45 of FIG. 5), the counterpart terminal specifying unit 151 cancels the pairing process Then, the pairing failure is notified to the user (S51). For example, as illustrated in (e) of FIG. 4, when the terminal in the Bluetooth communicable range in the smartphone 1 is only the smartphone 2 that does not execute the pair application (the terminal name is not changed), the smartphone 1 Displays on the display unit 22 that a partner terminal with which to establish pairing is not found. More specifically, the counterpart terminal specifying unit 151 in the smartphone 1 notifies the application executing unit 12 that a counterpart terminal for establishing pairing is not found. Upon receiving the notification, the application execution unit 12 instructs the display control unit 14 to display an image indicating that the partner terminal is not found. Upon receiving the instruction, the display control unit 14 causes the display unit 22 to display an image indicating that the counterpart terminal cannot be found (for example, the image shown in FIG. 4E). Note that the notification to the user of the pairing failure is not limited to the display of the image, and may be a notification by voice or a notification by vibration.

[Embodiment 2]
The following will describe another embodiment of the present invention with reference to FIGS. FIG. 7 is a diagram illustrating 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 flowchart showing an example of the flow of the process “B” in FIG. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

As described in the first embodiment, the smartphone 1 and the smartphone 2 change the terminal name as the pair application is executed. That is, for the user, even if a character string desired by the user is set as the terminal name of his / her smartphone, the terminal name is forcibly changed. In other words, the terminal name desired by the user may be changed and the user may be dissatisfied. In addition, since the terminal name becomes a character string that is not familiar to the user, the user may be confused.

Therefore, as shown in FIG. 7, the smartphone 1 and the smartphone 2 according to the present embodiment restore the terminal names of their own terminals when pairing is established. Specifically, in order to identify the partner with whom pairing is established while the pairing process is being executed, the terminal name “<app name> _ <acquired” is acquired as shown in FIG. Time> ”. On the other hand, when the pairing is established, as shown in FIG. 7B, the terminal name of the own terminal is returned to the original terminal name. In the example of FIG. 7B, the smartphone 1 returns the terminal name to A0001, and the smartphone 2 returns the terminal name to A0002.

The pairing process in the present embodiment, particularly the process for returning the terminal name described above, will be described in more detail with reference to FIGS. 8 is the same as the processing from step S31 to step S49 in FIG. 5, and thus the description thereof is omitted here.

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. Upon receiving the notification, the device name changing unit 123 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 the terminal name. In the example of FIG. 7, the device name changing unit 123 returns the terminal name to “A0001”.

Then, the device name changing unit 123 supplies the original terminal name (“A0001” in this example) 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.

In contrast, when the smartphone 2 receives a pairing request from another terminal (smartphone 1 in this example), the smartphone 2 cancels the search for the terminal having <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 (smart phone 1 in this example) that transmitted the pairing request (S103). Note that details of the processing in step S101 and step S103 have already been described in the first embodiment, and thus description thereof is omitted here.

Then, the smartphone 2 restores the terminal name (S105). In the example of FIG. 7, the device name changing unit 123 returns the terminal name to “A0002”. The details of this processing are the same as the processing from step S91 to step S93 in the smartphone 1, and thus the description thereof is omitted here. 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 acquire the original terminal name of a partner terminal mutually.

As described above, when the pairing is established, the smartphone 1 and the smartphone 2 of the present embodiment restore the changed terminal name. This can prevent the user from being frustrated or confused.

[Embodiment 3]
The following will describe still another embodiment of the present invention with reference to FIG. FIG. 10 is a block diagram illustrating an example of a main configuration of the smartphone 3 and the smartphone 4 according to the present embodiment. For convenience of explanation, members having the same functions as those described in the embodiment are given the same reference numerals, and descriptions thereof are omitted.

In the above-described first and second embodiments, the terminal name is changed to “<application name> _ <acquired time>” in order to identify the partner terminal with which pairing is established. And the other party which establishes pairing was specified using the numerical sequence which enters <acquired time>. However, the terminal name after the change is not limited to “<application name> _ <acquired time>”, and the information used to identify the partner terminal with which pairing is established is not limited to the acquired time.

The control unit 10 of the smartphone 3 according to the present embodiment includes an application execution unit 16 instead of the application execution unit 12, and the application execution unit 16 includes not the time acquisition unit 122 but the condition information acquisition unit 126. Further, the RAM 30 of the smartphone 3 newly stores position information 36, a CPU specification 37, and a radio wave intensity 38.

The condition information acquisition unit 126 acquires various information used as a condition for specifying a partner terminal with which pairing is established. The condition information acquisition unit 126 according to the present embodiment acquires the position information of the smartphone 3, the CPU specifications of the smartphone 1, and the current radio wave intensity in addition to the time information described in the first embodiment. Here, the position information of the smartphone 3 may be 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 Wi-Fi communication via an access point, the relative position information 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. 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. Further, the device name changing unit 123 changes the terminal name using the supplied various information. That is, the changed terminal name in the present embodiment includes an application name, time, position information, CPU specifications, and radio wave intensity.

The counterpart terminal specifying unit 151 according to the present embodiment executes the specification of the counterpart terminal using the location information, the CPU specifications, and the radio wave intensity in addition to the specification of the counterpart terminal for pairing using the time included in the changed terminal name.

Specifically, the counterpart terminal specifying unit 151 refers to the position information in the changed terminal name, and includes a terminal that includes position information indicating the position closest to the position indicated by the position information of the own terminal (smartphone 3) in the terminal name. Identify. When displaying an image over two smartphones, the user often displays the two smartphones side by side as shown in FIG. That is, the terminal that includes the position information indicating the position closest to the position indicated by the position information of the smartphone 3 in the terminal name is highly likely that the user is a partner terminal (smartphone 4) that is trying to establish pairing with the smartphone 3. . Therefore, the counterpart terminal specifying unit 151 of the present embodiment performs specification using the position information as described above, and correctly specifies the counterpart terminal that the user is trying to establish pairing with.

Also, the counterpart terminal specifying unit 151 specifies a terminal whose CPU specification in the changed terminal name is equal to or greater than a predetermined threshold among the terminals whose changed terminal name includes <application name>. When data (for example, image data) is transmitted from one of two smartphones with which pairing has been established to the other smartphone, if the CPU specification of the other smartphone is low, data transmission takes time. . Therefore, the counterpart terminal identification unit 151 of the present embodiment performs identification using the CPU specifications as described above, and establishes pairing between smartphones so that smooth data transmission / reception can be realized.

Further, the counterpart terminal specifying unit 151 specifies a terminal having a radio field intensity equal to or higher than a predetermined threshold among terminals including <application name> in the changed terminal name. Here, there is a high possibility that a smartphone with high radio field intensity is a smartphone closer to the terminal itself. Therefore, the partner terminal specifying unit 151 of the embodiment performs the specification using the above-described radio wave intensity, and correctly specifies the partner terminal that the user is trying to establish pairing with.

In addition, since each part of the smart phone 4 which concerns on this embodiment has the same function as the member which has the same member name in the smart phone 3, 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.

In this embodiment, the time, position information, CPU specifications, and radio wave intensity are acquired as various information, but the present invention is not limited to this example. That is, the acquired information 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, the example in which the terminal name is changed as the terminal identifier in order to establish communication by Bluetooth has been described. However, the terminal identifier is not limited to the terminal name. For example, when establishing Wi-Fi communication via an access point, the identifier (SSID) of an access point connected to be communicable with each terminal may be changed.

In Embodiments 1 to 3, the first half of the changed terminal name is the application name, but it is common for smartphones that want to establish communication, and it is understood that they have the functions that they want to realize. If it is such, it will not be limited to an application name, Information (validation information) which consists of at least one of a character, a number, and a symbol may be sufficient. Moreover, the user may be able to freely set the activation information.

Also, depending on the terminal, there may be a case where communication by a plurality of communication methods is possible. Therefore, the first half of the changed terminal name is used as information indicating whether the application name and each communication method are supported, and the counterpart terminal identifying unit 151 is configured to identify a terminal whose first half is completely matched. There may be. For example, if a terminal can communicate via Bluetooth, can communicate via an access point via Wi-Fi, can communicate via an access point via Wi-Fi, or cannot communicate via NFC, the first half of the changed terminal name is “ Pair application 1110 ”.

Further, as shown in FIG. 2D, the smartphone 1 and the smartphone 2 display image candidates to be displayed across both terminals on the display unit 22, and the candidates are determined according to preset category information. May be. Specifically, the application execution unit 12 presets category information corresponding to the user operation. The category information is, for example, “Latest day” or “September 22 Hokkaido travel photo”, and the application execution unit 12 specifies the image data 41 according to the set category information. 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 according to the set category information by referring to the date and time information and the position information added to the image data 41. In addition, the application execution unit 12 may add various types of 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 of images on the vertical axis, the portion where many photographs are displayed at the same position on the horizontal axis is traveled. It can be specified that it is a photograph at the time. If the location information can be acquired from the additional information of the photo included in this part, the category information such as the above-mentioned “photo of Hokkaido trip on 9/22” can be added to the photo included in this part.

Also, the resolution on the touch panel 20 and the size of the display area may be transmitted to the partner terminal. Thereby, since the smart phone 1 can acquire the resolution of the other party terminal (smart phone 2) and the size of the display area, as shown in (e) of FIG. 2, the touch when the image β is selected and dragged and dropped. Based on the coordinate trajectory, how the smartphone 1 and the smartphone 2 are arranged, more specifically, two smartphones adjacent to each other forming the rectangular smartphone 1 and the smartphone 2 are adjacent to each other. Thus, it is possible to specify from where to where the contact is in contact.

That is, when the user performs a drag and drop operation, the touch acquisition unit 11 identifies the touch coordinates on the contact side of the smartphone 1 and the touch coordinates on the contact side of the smartphone 2. Also, the coordinates of the start point and end point of the operation are specified. And the application execution part 12 can pinpoint the direction of the said operation from these coordinates. In addition, the application execution unit 12 can determine which of the smartphone 1 and the smartphone 2 is using the resolution of the own device and the size of the display area, the resolution of the counterpart terminal and the size of the display area, and the specified touch coordinates and operation direction. In other words, it is possible to specify the shape of the connected display area composed of the display areas of the two smartphones. And the application execution part 12 of the smart phone 1 is the part displayed on the display area of the smart phone 1 among the image data 41 to display according to the arrangement | positioning relationship (shape of a connection display area) of the smart phone 1 and the smart phone 2 which were specified. And the part displayed on the display area of the smart phone 2 is each specified.

Thereby, even if it is a case where the smart phone 1 and the smart phone 2 are arrange | positioned and shifted (there is a part which is not in contact with the other party terminal in a contact side), the image data 41 displayed over two smart phones, It is possible to display without any deviation. For example, even if the display areas of the smartphone 1 and the smartphone 2 are different in size, the image data 41 displayed over the two smartphones can be displayed without any deviation.

[Example of software implementation]
The control blocks (especially 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) of the smartphones 1 to 4 are logical circuits (IC chips) formed in an integrated circuit (IC chip) or the like. Hardware) or software using a CPU (Central Processing Unit).

In the latter case, the smartphones 1 to 4 include 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 recorded so as to be readable by the computer (or CPU). Alternatively, a storage device (these are referred to as “recording media”), a RAM (Random Access Memory) for expanding the program, and the like are provided. And the objective of this invention is achieved when a computer (or CPU) reads the said program from the said recording medium and runs it. As the recording medium, a “non-temporary tangible medium” such as 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 an arbitrary transmission medium (such as a communication network or a broadcast wave) that can transmit 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.
