  In the determination of S326 “start key pressed”, it is determined whether or not the start key provided in the designation means 48 has been pressed. This start key may be a dedicated start key, or the “↑ key” of the cross key 8 may be assigned. If the “start key” is not pressed, the process returns to S326 and loops again. If the “start key” is pressed, the process proceeds to the next S328 “connection confirmation transmission”.

  In the next S328, a command “confirmation of connection” indicating that communication is established from the communication terminal 40 to the electronic camera 10 wirelessly is transmitted, and the process proceeds to the next determination of S330 “buzzer sound detection”. If the buzzer sound emitted by the electronic camera 10 is not detected in S330, the process returns to S330 and loops again. If the buzzer sound generated by the electronic camera 10 is detected in S330, the process proceeds to S332 “Buzzer confirmation transmission”, and information indicating that the buzzer sound has been received is transmitted to the electronic camera 10. Then, the process proceeds to the next S334 “buzzer reply”.

  In S334, the “buzzer reply” information transmitted in S312 of the electronic camera 10 is received. If “buzzer reply” is not received, the process branches to S340 “END”, and “buzzer reply” is displayed. If received, the process proceeds to the next S336 “connection permission transmission”.

  When the authentication procedure is completed, the connection process with the electronic camera 10 is completed in S340 “END”, and the process returns to the original program routine.

  As described above, when a desired connected device is selected from the information of the connected device displayed on the communication terminal 40, a buzzer sound is emitted from the selected connected device, and the microphone 52 of the communication terminal 40 detects this buzzer sound. Then, the communication terminal 40 inquires whether a buzzer is sounded to a device existing within the communication connection range through wireless communication. When a reply indicating that a buzzer is sounding is received, the mutual authentication procedure can be executed to establish communication. In addition, when buzzer sounds are emitted from a plurality of connected devices, communication may be established only with the connected devices that are close to the communication terminal 40.

  When the electronic camera 10 and the communication terminal 40 enter the communication range, the devices recognize each other, and the program of the electronic camera 10 branches to S400 “START”. In the next S402 “search mode start”, a process of searching for the communication terminal 40 is started by emitting a radio wave including a search signal from the antenna 30 according to a command from the information processing means 14.

  Then, the process proceeds to the next S404 “strobe prohibition / macro position / movie through”, and after setting the operation mode of the electronic camera 10, the process proceeds to S406 “connection confirmation graphic”. In next step S406, the user photographs the “connection confirmation graphic” displayed on the display means 46 of the communication terminal 40 by the electronic camera 10, and the electronic camera 10 captures the display pattern and the blinking state of the display. The communication terminal 40 is recognized.

  If the “connection confirmation graphic” is recognized in S406, the process proceeds to the next S408 “movie through stop”, and the movie through mode set in S404 is stopped. In S410 “figure confirmation transmission”, information indicating that the figure displayed on the display means 46 has been confirmed is transmitted to the communication terminal 40, and the process proceeds to next S412 “connection permission reception”.

  In the next determination of S412 “connection permission reception”, if “connection permission” is not received from the communication terminal 40, the process returns to S412 again to loop S412 and receives “connection permission” from the communication terminal 40. If so, the process proceeds to the next S414 “authentication procedure” to perform communication relating to the authentication procedure. In S416 “END”, the communication connection process with the communication terminal 40 is completed, and the process returns to the original program routine.

  On the other hand, in the processing program of the communication terminal 40, when the electronic camera 10 and the communication terminal 40 enter the communication range, the communication terminal 40 recognizes this and branches to S420 “START”. In the next S422 “search mode start”, the CPU 62 emits a radio wave including a search signal from the wireless communication means 44 and starts a process of searching for a connected device. At this time, information such as the device name of the electronic camera 10 that is communicating and information such as the name of the connected device that is communicable in other communication areas are displayed, and the user selects and designates a desired device from among them. May be.

  When the search for connected devices is completed, the process proceeds to the next S424 “display connection confirmation graphic”, displays a predetermined display pattern on the display means 46, and proceeds to the next S426 “confirmation detection”. In S426, a process of waiting for a “figure confirmation” signal transmitted from the electronic camera 10 is performed. If the “graphic confirmation” is not received in S426, the program returns to S426 and loops again. If “graphic confirmation” is received, the program goes to the next S428 “connection permission transmission”. move on.

  In the next S428, a communication connection permission signal is transmitted from the communication terminal 40 to the electronic camera 10. Thereafter, the electronic camera 10 and the communication terminal 40 communicate with each other and establish mutual authentication in S430 “authentication procedure”.

  When the authentication procedure is completed, the connection process with the electronic camera 10 is completed in S432 “END”, and the process returns to the original program routine.

  The description of the flowchart in FIG. 9 is performed only for parts different from the flowchart shown in FIG.

  The difference from the processing program of the electronic camera 10 shown in FIG. 9 is that communication is performed by photographing the display pattern displayed on the display means 46 and the blinking state of the display performed in S406 “connection confirmation figure” of FIG. Instead of recognizing the terminal 40, the “connection confirmation blinking display” displayed on the display means 46 in S407 “confirmation blinking period” is photographed to recognize the blinking period. The subsequent processing is performed in the same manner as the processing shown in FIG.

  Further, the difference from the processing program of the communication terminal 40 shown in FIG. 9 is that, instead of displaying “connection confirmation graphic” in S424 “connection confirmation graphic display” in FIG. This is the point that the display blinks at a predetermined cycle and the process of stopping the display blinking in S425 in S427 “stop blinking” with the confirmation detection in S426.

Judgment is made. If an impact is not detected, the process returns to S506 and loops again. If an impact is detected, the process proceeds to the next step S508 “Vibration monitoring stop”, the enable of the vibration detection means 15 is canceled, and the vibration is detected. Stop monitoring data.

  In the next S510 “shock confirmation transmission”, a process of transmitting “shock confirmation” information indicating the detection of the shock to the communication terminal 40 is performed, and the process proceeds to the next S512 “connection permission reception”.

Alternatively, a determination is made as to whether or not an impact sound that is higher than the volume is detected. If it is determined that the microphone input has not detected the impact sound, the loop processing is returned to S526 again. If it is determined that the microphone input has detected the impact sound, S528 “impact confirmation detection” is set. move on.

  When the authentication procedure is completed, the connection process with the electronic camera 10 is completed in S534 “END”, and the process returns to the original program routine.

  As described above, when the electronic camera 10 is automatically set to the impact confirmation mode and the electronic camera 10 and the communication terminal 40 are lightly brought into contact with each other to generate a contact sound, the communication terminal 40 uses the microphone 52 to make a contact sound. In addition, the electronic camera 10 can detect a shock caused by contact by the vibration detection means 15, execute a mutual authentication procedure, and establish communication. As the contact detection means, a camera shake detection sensor at the time of photographing may be used, a change in conductivity or a change in capacitance may be detected, or an electronic camera using an autofocus means.

  In S624 “product name request transmission”, the communication terminal 40 requests the electronic camera 10 to transmit an attribute such as a product name wirelessly. In the next S626 “Product Name Reception”, processing for waiting for reception of information related to the product name of the electronic camera 10 issued from the electronic camera 10 is performed. If “product name” is not received, the process branches back to S626 and loops. If “product name” is received, the process proceeds to S628 “product name display”.

  In the next S628 “product name display”, identification information such as the external shape and name of the connected device stored in the PROM 64 is displayed on the display means 46.

  FIG. 14 shows a display 45 of connected device identification information displayed on the display means 46 of the communication terminal 40.

  According to the figure, the display means 46 of the communication terminal 40 includes a battery remaining capacity display 82 that indicates the remaining capacity of the battery that is the power source of the communication terminal 40, and a received radio wave intensity display 84 that displays the radio received radio wave intensity. , And connected device name displays 86, 86... And a reverse display 88 when selecting the electronic camera 10 as the connected device.

  The embodiment of FIG. 15 adds a connection prohibition rejection setting mode to the program of the communication terminal 40 shown in FIG. 13 so that connection prohibition of wireless communication can be designated. Therefore, the description of the same flow as the flow described in the embodiment of FIG. 13 is omitted, and only a different flow will be described below.

  When the authentication procedure between the electronic camera 10 and the communication terminal 40 is completed in S644 “authentication procedure”, the process proceeds to the next S650 “rejection setting mode”.

  In S650, it is determined whether or not the rejection setting mode is designated by the designation means 48. At this time, the display means 46 may be notified of the setting purpose, setting method, and procedure to the user. If the refusal setting mode is not designated in S650, the process proceeds to S650 again to perform a loop process. If the refusal setting mode is designated, the process proceeds to the next S652 “Rejection setting display start” to display the display means.

  FIG. 17 shows a flowchart of another embodiment when the electronic camera 10 and the communication terminal 40 establish communication.

  When the electronic camera 10 and the communication terminal 40 enter the communication range, the devices recognize each other and the program of the electronic camera 10 branches to S700 “START”. In the next S702 “search mode start”, a process of searching for the communication terminal 40 is started by emitting a radio wave including a search signal from the antenna 30 according to a command from the information processing means 14.

  If the electronic camera 10 receives the search signal output from the communication terminal 40 in the determination of “There is a connectable device” in S704, the electronic camera 10 receives a unique address from the communication terminal 40 in order to establish communication. A process for newly joining a communication network and performing a connection handshake is entered. At this time, identification information such as the communication means on the display means 32 and the device name of the other party's connected device or communication terminal may be displayed, and the user may select and specify a desired device.

  In S706 “reception of connection confirmation”, a process of waiting for a “connection confirmation” signal transmitted from the communication terminal 40 to the electronic camera 10 wirelessly is performed. If “connection confirmation” has not been transmitted, the process returns to S706 again to loop S706, and if “connection confirmation” has been transmitted, the process proceeds to the next S708 “connection start transmission”.

  In the next S708 “connection start transmission”, a request command for performing “connection start” is transmitted from the electronic camera 10 to the communication terminal 40 automatically, and the determination of S714 “connection permission reception” is made. Proceed to

  In S714 “connection permission reception” determination, if “connection permission” is not received from the communication terminal 40, a loop is returned to S714 again. If “connection permission” is received from the communication terminal 40, the next step is performed. In step S716 “authentication procedure”, communication related to the authentication procedure is performed. In step S718 “END”, the communication connection process with the communication terminal 40 is completed, and the process returns to the original program routine.

  On the other hand, in the processing program of the communication terminal 40, when the electronic camera 10 and the communication terminal 40 enter the communication range, the communication terminal 40 recognizes this, and the program of the communication terminal 40 branches to S720 “START”. In next S722 “search mode start”, the CPU 62 emits a radio wave including a search signal from the wireless communication means 44, and starts a process of searching for a connected device. At this time, information such as the device name of the electronic camera 10 that is communicating and information such as the name of the connected device that is communicable within other communication areas are displayed, and the user selects a desired communication partner from these information May be specified.

  If the communication terminal 40 receives the search signal output from the electronic camera 10 in the determination of S724 “There is a connectable device”, the communication terminal 40 has joined the new communication network to establish communication. 40 is recognized, a unique address is assigned, and processing for connection handshake is started.

  In the next S728, a command “connection confirmation” indicating that communication is established from the communication terminal 40 to the electronic camera 10 wirelessly is transmitted, and the process proceeds to the next S730 “connection start reception”. In S730, a process of waiting for a “connection start” request command to be transmitted from the communication terminal 40 is performed. When the electronic camera 10 transmits a command requesting “connection start” in S708 “connection start transmission” and the communication terminal 40 receives the command, the process proceeds from S730 to S732 “connection permission transmission”.

  In S732 “connection permission transmission”, a communication connection permission signal is transmitted from the communication terminal 40 to the electronic camera 10. Thereafter, the electronic camera 10 and the communication terminal 40 communicate with each other and establish mutual authentication in S734 “authentication procedure”.

  When the authentication procedure is completed, the communication terminal 40 sounds a ringtone from the speaker 50 in S736 “ring ringtone” to notify the user that the communication connection has been established. Then, the process proceeds to the next S136 “END” to complete the connection process with the electronic camera 10 and return to the original program routine.

  In the above description, the example in which the user is notified by the sound emitted from the speaker 50 that the communication between the electronic camera 10 and the communication terminal 40 has been established has been described. However, the present invention is not limited to this. The user may be notified by display, lighting of the display, blinking, vibration, or the like.

  FIG. 18 is a flowchart of another embodiment when the electronic camera 10 and the communication terminal 40 shown in FIG. 17 establish communication. When communication is established by the method shown in FIG. 17, the authentication code of the electronic camera 10 is kept, but in the method shown in FIG. 18, “one-time mode” can be set after communication is established, and mutual authentication is performed. It is characterized by providing a mode that can be performed only once. When this “one-time mode” is set, it is effective when connection is transmitted only once such as commercial information and information is transmitted, and it is effective when subsequent communication is unnecessary, and thereafter unnecessary connection processing can be prevented. .

  The description of the flowchart in FIG. 9 is performed only for parts different from the flowchart shown in FIG.

  The difference from the processing program of the electronic camera 10 shown in FIG. 17 is a setting part of the one-time mode after S734 “authentication procedure” in FIG. When the authentication procedure of the electronic camera 10 is completed in S734, the process proceeds to a determination to set S740 “one-time mode”. Here, the display means 46 of the communication terminal 40 displays that the “one time mode” is set, and the user uses the specifying means 48 to set the “one time mode”. If the “one-time mode” is set in S740, the process proceeds to S742 “Authentication code prohibition setting”, the authentication code is canceled after the first communication, and the process proceeds to S744 “END”. If the “one-time mode” is not set in S740, the process directly proceeds to S744 “END” to complete the connection process with the electronic camera 10 and returns to the original program routine.

  FIG. 19 shows a flowchart for continuing or canceling the “one-time mode” in the communication terminal 40.

  When the setting for continuing or canceling the “one time mode” is designated, the program jumps to S750 “START”. In the next S752 “one-time cancellation mode”, it is determined whether or not the designation by the user input is “one-time cancellation mode”. If it is not “one-time cancellation”, the process branches to S756 “END”. If it is “one-time cancellation”, the process proceeds to S754 “recovery of forbidden authentication code”, and in S742 of FIG. A process of restoring the prohibited authentication code and establishing communication is performed, and the process returns to the original program routine.

  FIG. 20 is a flowchart of another embodiment when the electronic camera 10 and the communication terminal 40 shown in FIG. 17 establish communication. When communication is established by the connection method shown in FIG. 17, the communication terminal 40 emits a ringing tone to recognize the connection. However, in the connection method shown in FIG. 20, the authentication procedure is performed after connection of the first communication. A common key is used as user identification information, and a unique key is issued during the second authentication procedure after communication connection to obtain user identification information.

  Since the processing program of the electronic camera 10 shown in FIG. 20 and the flow shown in FIG. 17 are the same, description thereof will be omitted.

  The description of the flowchart of the communication terminal 40 in FIG. 20 will be made only on parts different from the flowchart shown in FIG. When the communication terminal 40 transmits “connection permission” to the electronic camera 10 in S732 “connection permission transmission”, the program proceeds to the next determination of S760 “first connection”. In S760, it is determined whether or not the current connection is the first (first) connection. If the current connection is the first time, the process proceeds to S762 “issue common key for authentication procedure”, performs an authentication procedure for the electronic camera 10, issues a “common key”, and a common key is pressed. Only establish a communication connection. When the processing of S762 ends, the process proceeds to the next S764 “END” and returns to the original program routine.

  If the current connection is not the first time, the process proceeds to S766 “second connection”. If it is determined in S766 that the current connection is the second time, S768 “issues an authentication procedure unique key”. ”, An authentication procedure is performed on the electronic camera 10 and a“ unique key ”is issued to establish a communication connection only when the unique key is pressed. When the processing of S768 ends, the process proceeds to the next S764 “END” and returns to the original program routine.

  If it is determined in S766 that the current connection is not the second connection (if it is the third or subsequent connection), the process proceeds to S772 “Unique key?” And whether or not the unique key issued in S768 has been pressed. Judgment is made. If the pressed key is not the unique key issued in S768, the process proceeds to S764 “END” and returns to the original subroutine. If the pressed key is the unique key issued in S768, the process proceeds to S772 “Authentication Procedure” to perform an authentication procedure for the electronic camera 10 to establish a communication connection. When the processing of S772 ends, the process proceeds to the next S764 “END” and returns to the original program routine.

  As described above, the user can be easily identified by using the common key and the unique key issued at the time of connection for identification.
