Restore information. Note that the restoration algorithm of the restoration unit 110a is the same as the generation algorithm in the second generation unit 109b.

  Next, the operation when transmitting and receiving data wirelessly in the imaging apparatus 1 (1A, 1B) constituting the wireless connection system 100 of the present embodiment will be described with reference to FIGS. Note that the processing flow in FIG. 4 is processing executed under the control of the central control unit 101 when the imaging apparatus 1 functions as a data transmission side, that is, as a storage server. The processing flow of FIG. 5 is a process executed under the control of the central control unit 101 when the imaging apparatus 1 functions as a data reception side, that is, a terminal that accesses a storage server and browses or downloads image data. It is.

First, the processing on the transmission side shown in FIG. 4 will be described. This processing on the transmission side is executed in response to a key information generation instruction from the operation input unit 107.
First, the first generation unit 109a generates key information for defining communication control information necessary for establishing communication with an external electronic device such as the imaging device 1 on the receiving side (step S1). In step S1, the first generation unit 109a generates key information by randomly selecting and arranging four numbers from 0 to 9, as described above, and the display control unit of the display unit 105 105b and the second generator 109b.

When the key information is generated, the display control unit 105b of the display unit 105 displays the key information on the display panel 105a (step S2).
FIG. 6 shows an example of the key information display screen G1 displayed on the display panel 105a in step S2. As shown in FIG. 6, on the key information display screen G1, a message M1 such as “Please set this key information” and the key information K1 are displayed.
Thus, by presenting the key information display screen G1 displayed on the display panel 105a to the user of the external electronic device such as the imaging device 1 on the data receiving side, the key information is displayed to the user of the external electronic device on the data receiving side. Can tell directly.

  On the other hand, the second generation unit 109b generates SSID, Key, and receiver ID that are communication control information based on the key information generated by the first generation unit 109a, and outputs the generated SSID, Key, and receiver ID to the communication control information setting unit 109c. (Step S3).

  The communication control information setting unit 109c sets the communication control information generated by the second generation unit 109b, that is, the SSID, Key, and receiver ID in the wireless processing unit 108 (step S4). Thereby, the imaging device 1 can operate as a storage server / access point.

  When the communication control information is set, the wireless processing unit 108 transmits (broadcasts) the SSID (step S5) and waits for a connection request.

  When the wireless processing unit 108 receives the connection request from the external electronic device (step S6; YES), the connection permission unit 108a matches the SSID transmitted from the external electronic device that is set in the wireless processing unit 108. It is determined whether or not to perform (step S7). When it is determined that the SSID transmitted from the external electronic device does not match that set in the wireless processing unit 108 (step S7; NO), the connection permission unit 108a rejects the connection to the external electronic device that has made the connection request. (Step S9), and the process returns to Step S5.

  If the connection permission unit 108a determines that the SSID transmitted from the external electronic device matches that set in the wireless processing unit 108 (step S7; YES), the Key transmitted from the external electronic device is the wireless processing unit. It is determined whether or not it matches the value set in 108 (step S8). When it is determined that the Key transmitted from the external electronic device does not match that set in the wireless processing unit 108 (step S8; NO), the connection permission unit 108a denies the connection to the external electronic device that has made the connection request. Perform (step S9) and return to step S5.

  On the other hand, when the connection permission unit 108a determines that the Key transmitted from the external electronic device matches that set in the wireless processing unit 108 (step S8; YES), the connection permission unit 108a connects to the external electronic device that requested the connection. Is established (step S10).

Next, the wireless processing unit 108 waits for reception of the receiver ID from the external electronic device that has made the connection request, and receives the receiver ID (step S11; YES), the connection permission unit 108a causes the received receiver ID to be wirelessly received. It is determined whether or not it matches that set in the processing unit 108 (step S12). If it is determined that the received receiver ID does not match that set in the wireless processing unit 108 (step S12; NO), the connection permission unit 108a performs a disconnection process (step S16).
When it is determined that the received receiver ID matches that set in the wireless processing unit 108 (step S12; YES), the connection permission unit 108a transmits a connection permission notification to the external electronic device that is the connection request source. (Step S13).

  When transmission target data (here, image data stored in the recording medium M) is designated by the operation input unit 107 or by a request from an external electronic device, the recording medium control unit 106 records. Corresponding image data is read from the medium M (step S14). The wireless processing unit 108 transmits the read image data to the connection request source external device (step S15). Then, when a certain time has passed or a disconnection request is received, a disconnection process is performed (step S16). After the disconnection process, when an input operation for canceling the setting of communication control information is detected from the operation input unit 107 or a request from an external electronic device, the setting of the communication control information in the wireless processing unit 108 is cancelled. . As a result, the operation mode as the storage server / access point is canceled.

  Next, processing on the receiving side shown in FIG. 5 will be described. This processing on the receiving side is executed in response to a key information input instruction from the operation input unit 107.

First, the display control unit 105b of the display unit 105 displays a key information input screen G2 for inputting key information on the display panel 105a (step S21).
FIG. 7 shows an example of the key information input screen G2 displayed on the display panel 105a in step S21. As shown in FIG. 7, in the key information input screen G2, a message M2 such as “Please enter the key information of the other party's screen” and an input for inputting four-digit key information by pressing the arrow key Column R1 is displayed. When each digit column of the input column R1 is touch-operated, arrow keys are displayed up and down. The user can easily input key information of each digit by touching an arrow key.
The touch panel of the operation input unit 107 detects the operated position information and inputs it to the central control unit 101 for each touch operation. When the position information detected from the operation input unit 107 is the position of the arrow key, the central control unit 101 counts the number of touch operations and identifies the input key information.

  When the input operation of key information from the key information input screen G2 is detected by the touch panel of the operation input unit 107, the central control unit 101 specifies the input key information and outputs it to the restoration unit 110a (step S22). Based on the detected key information, the restoration unit 110a restores the SSID, Key, and receiver ID, which are communication control information, and outputs them to the wireless processing unit 108 (step S23). Since the process in step S23 is the same as that in step S3, the description is incorporated.

  When the communication control information is restored, the wireless processing unit 108 searches for a storage server functioning as an access point that is transmitting the restored SSID (step S24). If found (step S25; YES), the connection request unit 108b transmits a connection request using the restored communication control information (SSID, Key) (step S26).

  In the wireless processing unit 108, when the connection is rejected (step S27; NO), the display control unit 105b displays an error message such as “connection refused” on the display panel 105a (step S32). The process ends.

  On the other hand, if the connection is successful and the connection is established in the wireless processing unit 108 (step S27; YES), the wireless processing unit 108 transmits the receiver ID of the communication control information (step S28). When the connection permission notification is received (step S29; YES), the wireless processing unit 108 receives the transmitted data (step S30). When the reception is completed and a certain time has elapsed or a disconnection request is received, the wireless processing unit 108 performs a disconnection process (step S31), and the process ends. In step S29, if the connection permission notification is not received even after a predetermined time has elapsed (step S29; NO), the wireless processing unit 108 performs a disconnection process, and the process ends.

As described above, when data transmission / reception is performed with the imaging device 1A as the data transmission side (first electronic device) and the imaging device 1B as the data reception side (second electronic device), the imaging device 1A performs the above transmission side processing. When the imaging apparatus 1B executes the above-described reception side processing, data transmission / reception is performed according to the following operation procedure.
First, in the imaging apparatus 1A, key information for defining communication control information is generated, the generated key information is displayed on the display panel 105a (see FIG. 6), and the SSID, Key, and receiver are generated from the generated key information. ID is generated. Then, the generated SSID is transmitted (broadcast).

Here, the user of the imaging apparatus 1A can directly convey the key information to the user of the imaging apparatus 1B by showing the key information displayed on the display panel 105a to the user of the imaging apparatus 1B.
The user of the imaging apparatus 1B looks at the key information displayed on the display panel 105a of the imaging apparatus 1A, operates the operation input unit 107 of the imaging apparatus 1B, and inputs the key information from the key information input screen G2.

  In the imaging apparatus 1B, when an input operation of key information is detected by the touch panel of the operation input unit 107, the SSID, Key, and receiver ID defined by the key information are restored from the input key information and restored. A connection request is made to the imaging apparatus 1A using the SSID, Key, and receiver ID.

When the imaging apparatus 1A receives the connection request from the imaging apparatus 1B, whether or not the SSID, Key, and receiver ID transmitted from the imaging apparatus 1B match the SSID, Key, and receiver ID generated from the key information, respectively. Is established, a connection with the imaging device 1B is established.
