Send and receive data. When the instruction to activate the short-range communication function is input, the mobile phone terminal 10 performs the process illustrated in FIG.

  When an instruction to activate the near field communication function is input, the main control unit 20 of the mobile phone terminal 10 captures an image with the camera 26 and selects a captured image and data to be transmitted as described above. Is displayed on the touch panel 12. When the main control unit 20 of the mobile phone terminal 10 displays the photographed image and the selection screen on the touch panel 12, whether or not the dragging of the object is started in step S12, that is, the input of the operation for moving the object is started. judge. In the present embodiment, the drag operation is used. However, as described above, various operations can be associated with the operation for moving the object by setting. The main controller 20 determines whether a drag operation has been input by detecting an operation on the touch panel 12.

  If the main control unit 20 determines in step S12 that dragging has not started (No), that is, the drag operation on the object has not been input, the main control unit 20 proceeds to step S12. That is, the main control unit 20 repeats the process of step S12 until the drag operation of the object is started. If the main control unit 20 determines in step S12 that the drag operation has started (Yes), in step S14, the main control unit 20 determines whether the object drag operation has ended. If the main control unit 20 determines in step S14 that the dragging has not ended (No), that is, the drag operation for the object is continuing, the main control unit 20 proceeds to step S14. That is, the main control unit 20 repeats the process of step S14 until the object drag operation is completed. If it is determined in step S14 that the dragging of the object has ended (Yes), the main control unit 20 determines in step S16 whether the dragged object is on the identifier. That is, the main control unit 20 determines whether the object has been moved over the identifier. The main control unit 20 detects the position of the identifier in the image by analyzing the captured image.

  If the main control unit 20 determines in step S16 that the position where the object is dragged (the position of the movement destination) is not on the identifier (No), the main control unit 20 proceeds to step S12. In this case, the main control unit 20 may process the input object drag operation as an object movement operation or invalidate the input operation.

  If the main control unit 20 determines in step S16 that the position where the object is dragged (the position of the movement destination) is on the identifier (Yes), the main control unit 20 performs identifier analysis in step S18 and acquires network ID information.

  Hereinafter, the identifier analysis processing in step S18 will be described with reference to FIG. As shown in FIG. 9, the main control unit 20 extracts an identifier from the photographed image as step S40. That is, the identifier included in the image photographed by the camera 26 is extracted. The identifier to be extracted is an identifier at the position where the object is dragged. Thereafter, the main control unit 20 analyzes the identifier extracted in step S40 as step S42. That is, the main control unit 20 analyzes the identifier based on the identifier display rule and extracts information included in the identifier. After analyzing the identifier in step S42, the main control unit 20 specifies the network ID from the analysis result in step S44. That is, the main control unit 20 specifies the network ID of the mobile phone terminal that includes the identifier included in the image based on the information extracted by analyzing the identifier. After performing the process of step S44, the main control unit 20 ends the identifier analysis process.

  When the main control unit 20 performs the identifier analysis in step S18 and acquires the network ID, the main control unit 20 performs connection processing in step S20.

  Hereinafter, the connection process in step S20 will be described with reference to FIG. In step S50, the main control unit 20 detects a communication terminal capable of short-range communication by the short-range communication unit 24. That is, the main control unit 20 detects a communication terminal having a short-range communication function including the mobile phone terminal 10b within a range where a communication wave output from the short-range communication unit 24 reaches. When the main control unit 20 detects the communication terminal in step S50, the main control unit 20 acquires the network ID of each communication terminal in step S52. That is, the main control unit 20 acquires a network ID as information for identifying which communication terminal is a communication terminal within a range where short-range communication is possible.

  After acquiring the network ID in step S52, the main control unit 20 determines whether there is a matching network ID in step S54. That is, it is determined whether there is a network ID that matches the network ID acquired in the identifier analysis in step S18 in the network ID acquired in step S54. If the main control unit 20 determines in step S54 that there is no matching network ID (No), the main control unit 20 proceeds to step S50, and performs the processing in step S50 and the processing in step S52 again.

  If the main control unit 20 determines in step S54 that there is a matching network ID (Yes), in step S56, the main control unit 20 assigns its own network ID to the target communication terminal (mobile phone terminal 10b in FIGS. 5 to 7). Send. That is, the main control unit 20 transmits information for the target communication terminal to identify the own device by short-range communication. When the main control unit 20 transmits its own network ID in step S56, the main control unit 20 performs setting processing in step S58. Note that the setting process is various setting processes that are executed in order to perform near field communication between two communication terminals (mobile phone terminals), and is used for exchanging or using a network ID corresponding to the process in step S56 described above. Communication wave system, frequency band, identification signal setting, synchronization processing, security setting processing, release processing, and the like. After performing the process of step S58, the main control unit 20 ends the connection process.

  After performing the connection process in step S20, the main control unit 20 determines in step S22 whether the connection destination is ready to receive an object. That is, it is determined whether the connection destination communication terminal is in a state in which information can be transmitted and received by short-range communication. If the main control unit 20 determines in step S22 that the connection destination is not in a state where object reception is possible (No), the main control unit 20 proceeds to step S22. That is, the main control unit 20 repeats the process of step S22 until the connection destination becomes ready to receive an object.

  If the main control unit 20 determines in step S22 that the connection destination is ready to receive an object (Yes), the main control unit 20 performs object transmission processing in step S24. Specifically, the main control unit 20 transmits data corresponding to the object dragged onto the identifier in step S16 to the communication terminal connected in step S20 by short-range communication.

  After performing the object transmission process in step S24, the main control unit 20 determines whether the object transmission is successful in step S26. If the main control unit 20 determines in step S26 that the object transmission has been successful (Yes), the main control unit 20 displays an image of successful transmission on the touch panel 12 in step S28. If the main control unit 20 determines in step S26 that the object transmission has not succeeded (No), that is, has failed, the main control unit 20 causes the touch panel 12 to display a transmission failure image in step S30. When the process of step S28 or step S30 ends, the main control unit 20 ends this process.

  As described above, the mobile phone terminal 10 reads the identifier provided in the communication terminal subject to short-range communication by the camera 26 and detects the network ID of the communication terminal subject to communication from the identifier. Thereby, even when there are a plurality of communication terminals capable of short-range communication, the user can specify the communication target communication terminal only by acquiring an image of the identifier of the communication target communication target with the camera 26. . That is, the user can select a target communication terminal from a plurality of communication terminals without exchanging network ID information with the user of the target communication terminal. As a result, the user can omit the trouble of identifying the network ID, which is a list of numbers or alphabets, and the operation load is reduced.

  In addition, the mobile phone terminal 10 transmits data to the communication terminal that is taking a picture with the camera 26, so that even if a large number of communication terminals are within a short-range communication range, the mobile phone terminal 10 is surely connected to the communication terminal in front of the user. Can send data to. Thereby, the possibility that the user mistakes the communication terminal can be reduced as compared with the case where the user manually selects the target communication terminal from the network IDs of the plurality of communication terminals, and the safety can be improved.

  Further, as in the present embodiment, the mobile phone terminal 10 causes the touch panel 12 to display the target communication terminal and the image of the identifier and the object of the target data to be transmitted, and the object moved to the identifier is the communication of the identifier. By transmitting to a terminal by near field communication, the user can transmit data of a desired object to a desired communication terminal with a simpler operation. Note that the method for selecting an object to be transmitted is not limited to this embodiment. For example, the mobile phone terminal 10 may set the object to be transmitted in advance, then capture the identifier of the target communication terminal with a camera, and execute the processing from step S18 onward in FIG.

  By using a camera as a device for acquiring identifier information, the mobile phone terminal 10 can be operated while viewing the acquired image, and the operation of the user can be simplified. In addition to the camera, various reading devices can be used as the identifier reading unit that acquires identifier information. Further, in the present embodiment, the mobile phone terminal 10 can more appropriately confirm whether the identifier is in the reading area of the identifier reading unit by configuring the identifier so that the identifier can be visually recognized. Can be. The identifier may be an image that cannot be viewed, for example, an image that can be read by infrared rays. By making the image invisible in this way, the two-dimensional code can be prevented from being visually recognized, and the design of the housing 11 can be improved. Moreover, it can suppress that an identifier is recognized by the other user, and can improve security.

  Here, in the communication system 1 and the mobile phone terminal 10, the two mobile phone terminals 10 that communicate with each other include the camera 26 and the identifier display unit 28, and the identifier display unit 28 and the camera 26 are used to acquire each other's identifier. Then, it is preferable to acquire each network ID and then exchange the network ID of the target mobile phone terminal 10 acquired with the network ID of the own device and the identifier in short-range communication. Thereby, since the connection process of step S20 of FIG. 8 can be performed in a state where the mutual network IDs have been acquired, it is possible to perform near field communication between the target mobile phone terminals 10 more reliably. Note that the communication system 1 and the mobile phone terminal 10 use the network ID based on the identifier of the other mobile phone terminal 10 read by the one mobile phone terminal 10 with the camera 26, and exchange of information thereafter is a short-range communication. You may make it carry out. In this case, one mobile phone terminal 10 transmits the network ID of the own device in association with the acquired network ID, so that the other mobile phone terminal 10 can specify the mobile phone terminal 10 to be communicated.

  In addition, the mobile phone terminal 10 is connected to a communication terminal that is a communication target that is arranged to face each other by arranging the camera 26 and the identifier display unit 28 on the same surface of the housing 11 as in the present embodiment. The image of the communication terminal to be communicated can be acquired in a state where the identifier is visible. Thereby, various processes can be performed rapidly.

  Hereinafter, another example in which the mobile phone terminal transmits and receives data in the short-range communication operation will be described with reference to FIGS. 11 and 12. FIG. 11 is an explanatory diagram for explaining the short-range communication operation of the mobile phone terminal. FIG. 12 is an explanatory diagram for explaining the short-range communication operation of the mobile phone terminal. In the example shown in FIGS. 11 and 12, the mobile phone terminal 10a and the mobile phone terminal 10b are arranged with their backs facing each other. In addition, the mobile phone terminal 10a includes the identifier display unit 28 of the mobile phone terminal 10b in the shooting area of the camera 26 of its own device.

  Similarly to the above-described embodiment, when each function is activated, the mobile phone terminal 10a captures an image by the camera 26, and an image 51 captured on a part of the touch panel 12 as shown in Step S3 of FIG. Display. The captured image 51 includes an image 60 of the mobile phone terminal 10b in the imaging area. The photographed image 51 includes an identifier image 62 displayed on the identifier display unit 28 of the mobile phone terminal 10b. The mobile phone terminal 10a also displays a selection screen 52 on the touch panel 12. On the selection screen 52, a plurality of objects of data to be transmitted by near field communication are displayed.

  In the state where the mobile phone terminal 10a displays the image 51 and the selection screen 52 as shown in step S3, an operation for designating the identifier image 62 on the touch panel 12 is input by the user's finger H, and then the step As shown in S4, when an operation for moving the finger H specifying the image 62 to the area 62a of the selection screen 52, that is, an operation for moving the finger along the arrow 72, is specified by the identifier of the image 62. The process of acquiring the profile information of the mobile phone terminal 10b is started. Specifically, the mobile phone terminal 10a sends a request for transmitting the profile information of the mobile phone terminal 10b to the mobile phone terminal 10b by short-range communication.

  When the process of step S4 in FIG. 11 is executed, the mobile phone terminal 10b displays an image 74 on the touch panel 12, as shown in FIG. The image 74 includes an item for inputting a selection operation as to whether or not to transmit the profile information of the own device to the mobile phone terminal 10a. When an operation for selecting transmission of profile information is input to the touch panel 12, the mobile phone terminal 10b transmits the profile information from the mobile phone terminal 10b to the mobile phone terminal 10a by short-range communication. When an operation for selecting not to transmit the profile information is input to the touch panel 12, the mobile phone terminal 10b transmits information indicating that the profile information is not transmitted to the mobile phone terminal 10a.

  In this way, the communication system 1 and the mobile phone terminal 10 associate the drag operation of the identifier with the operation of acquiring the profile information (information such as an address and a telephone number) of the mobile phone terminal 10 having the identifier. Can be replaced with simpler operations.

  Next, FIG. 13 is an explanatory diagram for explaining the near field communication operation of the mobile phone terminal. In the communication system 1 and the mobile phone terminal 10, when a plurality of mobile phone terminals are included in an image photographed by the camera, the mobile phone terminal 10 that transmits object data by short-range communication according to the position to which the object is moved. It can also be specified.

  When each function is activated, the mobile phone terminal 10a captures an image with the camera 26 and displays the captured image 81 on a part of the touch panel 12 as shown in step S5 of FIG. The captured image 81 includes images 82, 84, and 86 of the three mobile phone terminals 10 in the imaging area. The captured image 81 also includes identifier images 83, 85, and 87 displayed on the identifier display unit 28 of the three mobile phone terminals 10. The mobile phone terminal 10a also displays a selection screen 52 on the touch panel 12. On the selection screen 52, a plurality of objects 64 and 64a of data to be transmitted by near field communication are displayed.

  In the state where the mobile phone terminal 10a displays the image 81 and the selection screen 52 as shown in step S5, an operation for designating the object 64a on the touch panel 12 is input by the user's finger H, and then in step S6. As illustrated, when an operation for moving the finger H designating the object 64a to the image 83, that is, an operation for moving the finger H along the arrow, is input, the data corresponding to the object 64a is transmitted to the image 82 and the image by short-range communication. The mobile phone terminal 10 corresponding to the image 83 is transmitted. That is, the mobile phone terminal 10a specifies one mobile phone terminal from the three mobile phone terminals in the image 81 based on the identifier image 83, and performs short-range communication with the specified mobile phone terminal.

  As described above, when the mobile phone terminal 10 uses the identifier, when there are a plurality of mobile phone terminals in the shooting area of the camera, that is, when there are a plurality of communication terminals at positions facing the own device, a plurality of communication terminals are used. Even when they are arranged close to each other, it is possible to perform short-distance communication with a specific mobile phone terminal with a simple operation, and to transmit and receive data. Further, as in the present embodiment, by specifying the object data to be transmitted by the drag operation of the object and the mobile phone terminal to be transmitted, the mobile phone terminal sequentially performs various data on the various mobile phone terminals by a simple operation. Can be transmitted by short-range communication.

  14 and 15 are explanatory diagrams for explaining images to be displayed on the identifier display unit. Here, various methods can be used as a method of displaying the identifier on the identifier display unit 28. The identifier display unit 28 may display all information to be displayed as identifiers at once, but may display the information divided into a plurality of pieces. For example, as shown in FIG. 14, an identifier 90 composed of a two-dimensional code is divided into nine division identifiers 92a to 92i. As shown in FIG. 15, the identifier display unit 28 may switch the nine divided identifiers 92a to 92i and display them in order. In this case, one identifier 90 can be acquired by the camera (identifier reading unit) sequentially acquiring, storing, and synthesizing the images of the divided identifiers 92a to 92i.

  By dividing one identifier into a plurality of identifiers in this way, a complicated identifier can be used even if the identifier display unit 28 has a simple configuration, that is, even if the number of pixels of the identifier display unit 28 is reduced. Thereby, the configuration of the identifier display unit 28 can be simplified and more information can be displayed as an identifier. Also, by changing the image displayed in time series, it takes a certain time to transmit the identifier, so that only the intended partner can display and recognize the identifier. Thereby, security can be enhanced.

  In addition, the mobile phone terminal 10 can include various information used in short-range communication other than the network ID in the identifier. For example, an encryption key can be included in the identifier, and short-range communication cannot be performed unless the encryption of the network ID is released with the encryption key. Also, security can be enhanced by combining a plurality of codes.

  In addition, the mobile phone terminal can use various identifiers as identifiers to be displayed as described above by using an image display device that can switch the display as an identifier display unit that displays identifiers. Can be displayed. In addition, display and non-display can be switched, and the identifier can be changed, so that security can be enhanced. In addition, it is preferable to use an image display device for the identifier display unit because of the above effects, but the present invention is not limited to this. Note that the paper on which the identifier is printed is preferably attached to the housing 11. As described above, even when the identifier display unit is a paper whose identifier does not change, the network ID can be acquired by reading the identifier.
