When taking a digital image with the mobile phone 100, the camera unit 102 is activated by the control unit 106 in response to a user performing a predetermined operation with the key input unit 105. The activated camera unit 102 repeats the process of returning data obtained by the image receiving element from the subject image acquired by the optical system at a predetermined exposure time to the control unit 106 at predetermined time intervals, and the control unit 106 displays the data at the display unit. The live view function is realized by displaying on 104. In this state, when the user further performs a predetermined operation with the key input unit 105, the camera unit 102 generates image data under the shooting conditions set from the subject image acquired by the optical system, and the generated image data Is stored in the storage unit 109 by the control unit 106. Further, the camera unit 102 has a mode of operating as a code reader that causes the code recognition unit 101 to recognize the acquired image data. In such a mode, the control unit 106 sequentially delivers the image data received from the camera unit 102 to the code recognition unit 101 (to be described later) while realizing the above-described live view function in the activated camera unit 102 to perform code recognition. The unit 101 attempts to decode the image data. When the image data can be decoded, the obtained data is transferred to the control unit 106.

  The code reader unit 103 provides a function of recognizing and decoding the two-dimensional code image data acquired by the camera unit 102 and obtaining original data encoded in the two-dimensional code. The code reader unit 103 corresponds to the QR code defined in JISX0510. The code reader unit 103 recognizes and decodes the coded QR code by dividing the data into a plurality of QR codes, and connects the decoded results to the original data. It has the function to acquire. Such a code reader unit 103 can be virtually configured by executing a predetermined program on the control unit 106 described later, but part or all of the functions can also be configured by hardware. is there.

  Thus, the code recognition unit 101 that recognizes the two-dimensional code is configured by the cooperation of the camera unit 102 and the code reader unit 103 in the present embodiment.

  The display unit 104 is a liquid crystal display device or an organic liquid crystal display device, and displays the operating state of the mobile phone 100, a user interface for operating the mobile phone 100, and the like under the control of the control unit 106. Further, in the present embodiment, when the mobile phone 100 is used as a data providing device, a plurality of QR codes obtained by dividing and coding predetermined data are continuously displayed on the display unit 104.

The control unit 106 includes a camera unit 102, a code reader unit 103, a display unit 104, and key inputs of the mobile phone 100. Various functions of the mobile phone 100 are realized by exchanging data and control signals with the functional blocks such as the unit 105, the communication unit 107, the code generation unit 108, and the storage unit 109.

  The communication unit 107 operates under the control of the control unit 106 to provide a function of connecting to a mobile communication network and performing communication with another node. Examples of the communication here include circuit-switched communication performed by communication connection with another mobile phone or fixed telephone, packet-switched communication performed by connection with another mobile phone or server, and the like.

  The code generation unit 108 operates under the control of the control unit 106 to perform processing for encoding predetermined data designated by the key input unit 105 into a QR code. At this time, if the size of the designated data is large, the data is divided into a plurality of QR codes for encoding. A method for coding data by dividing it into a plurality of QR codes can be implemented in accordance with JIS X0510. Here, when certain data is divided and coded to generate QR codes of QR (1) to QR (n), each i-th QR (i) is connected to the first symbol character (concatenated). A mode identifier, i, n) is described. Thereby, the code reader side determines that the read QR code is divided and coded, what number QR code is divided, and how many QR codes are divided as a whole. It is possible to know that. FIG. 2 shows an example of QR codes 111a to 111d generated from predetermined data by the code generation unit 108.

Both the image captured by the camera unit 102 and the QR code generated by the code generation unit 108 are stored in the storage unit 109.

  Hereinafter, the operation of the data providing system using the mobile phone 100 of the present embodiment as the data providing device and the data receiving device will be described. First, a first operation using the mobile phone 100 as a data providing device will be described with reference to the flowchart of FIG.

  This operation is started by performing a predetermined operation with the key input unit 105 of the mobile phone 100. First, the user operates the key input unit 105 to select a data file to be provided (ST101). More specifically, the control unit 106 displays a file list on the display unit 104, and in this state, the user operates the key input unit 105 to select a file from the list, and the selected file name or ID is displayed. This is performed by notifying the control unit 106.

  Next, the selected file is processed by the code generation unit 108, and QR (1). . . QR (n) is generated (ST102). That is, upon receiving notification of the selected file name or ID, the control unit 106 activates the code generation unit 108, divides the file, and performs QR (1). . . It is encoded into QR (n) and recorded in the storage unit 109.

  When the generation of the QR code is completed, the control unit 106 initializes the parameter i = 0 (ST103), increments it to i = i + 1 (ST104), and then displays QR (i) on the display unit 104 (ST105). At this time, QR (i) is displayed at a fixed position on the display unit 104.

  After starting the display of QR (i) in ST105, control unit 106 determines whether or not the display time of QR (i) has reached a predetermined value (ST106). If it is determined that the predetermined value has not been reached, the process does not proceed to the subsequent steps, and the determination in ST106 is repeated. On the other hand, when it is determined that the predetermined value is exceeded, the control unit 106 first determines whether or not an end instruction is input from the user (ST107), and determines that the end instruction is input. The process ends. On the other hand, if it is determined that the end instruction has not been input, it is determined whether i = n related to QR (i) being displayed (ST108), and if i = n is determined. Return to ST103 and repeat the process of initializing i, and if i = n is not determined, return to ST104 and repeat the process of incrementing i.

  Through the first operation as described above, the mobile phone 100 divides the selected file into a plurality of QR codes by coding, and the obtained QR code is displayed at a predetermined position of the display unit 104 with QR (1 ) To QR (n) are continuously displayed for a predetermined period of time until an end instruction is input, and functions as a data providing device.

  Next, a second operation using the mobile phone 100 as a data receiving device will be described with reference to the flowchart of FIG. This operation is started by performing a predetermined operation with the key input unit 105 of the mobile phone 100. First, the control unit 106 activates the camera unit 102 to capture an image (ST201). Next, the control unit 106 delivers the captured image to the code reader unit 103, and determines whether the QR code is included in the image captured by the code reader unit 103 (ST202).

  If it is not determined in ST202 that the QR code is included, the process returns to ST201 to capture an image again. On the other hand, if it is determined that the QR code is included, the code reader unit 103 reads the QR code from the captured image and performs decoding (ST203). From this decoding result, the control unit 106 determines whether or not the read QR code has been recognized (STEP 204). In this determination, information on (connection mode identifier, i, n) is acquired from the first symbol character of the read QR code, and the control unit 106 determines whether or not the i-th QR code has been read. Can be performed.

  If it is determined in ST204 that the image has been recognized, the process returns to ST201 to capture an image again. On the other hand, if it is not determined that the code has been recognized, the control unit 106 stores the result decoded by the code reader unit 103 in the storage unit 109 (ST205), and the control unit 106 generates all the QR codes generated in the connection mode. Is recognized (ST206). This determination can be made by referring to the decoding result stored in the storage unit 109. However, in ST205, the decoding result is stored in the storage unit 109 and what QR code is recognized. This history may be recorded in a table, and the determination may be made by referring to this table.

  If it is not determined in ST206 that all QR codes have been recognized, the process returns to ST201 and the subsequent processing is repeated. On the other hand, when it is determined that all QR codes have been recognized, the control unit 106 ends the capture operation of the camera unit 102 (ST207), and displays the decoding result stored in the storage unit 109. The file obtained by concatenation is stored in the storage unit 109 (ST208).

  Through the second operation as described above, the mobile phone 100 continuously recognizes a plurality of QR codes generated by dividing and encoding a predetermined file, and connects the decoded results to determine the predetermined file. It functions as a data receiving device that acquires the file.

  The data transfer system of the present invention is configured by using the cellular phone 100 having the above configuration and operation and the cellular phone 100 ′ configured similarly. That is, the mobile phone 100 ′ performs the first operation, and the mobile phone 100 ′ performs the second operation on the display unit 104 while displaying the QR code obtained by dividing and encoding predetermined data. By performing the above and continuously recognizing the QR code displayed on the display unit 104 of the mobile phone 100, predetermined data can be provided from the mobile phone 100 to the mobile phone 100 '. Thereby, it becomes possible to mutually provide and receive data at low cost by using a camera function having a high penetration rate without using a base station network or an expensive communication function between mobile phones. Therefore, in countries and regions where the cost of communication using a base station network is high, mobile phone data can be exchanged without being conscious of costs, and there is a way for users to effectively use various functions of mobile phones at low cost.
