The desktop videophone 20 is controlled to establish a videophone call by transmitting 26 captured images to another electronic device.

  Further, the permitted device database 45 is controlled by the main control unit 47 so that the desk-top videophone 20 is connected to other electronic devices so as to be capable of electrical communication and receives unique identification information (owner information) from the other electronic devices. This identification information is automatically stored (hereinafter referred to as automatic registration according to connection).

  In addition, in order for the user to arbitrarily limit the electronic devices to which the captured images of the imaging unit 26 are transmitted, automatic registration is performed according to the connection only during a period permitted by the main control unit 47 (hereinafter referred to as an automatic registration period). The desk-top videophone 20 may be configured to do this. For example, the main control unit 47 controls the automatic registration so that only a predetermined number (for example, three) of the desk videophone 20 is connected according to the connection from the first activation, and the registration is not permitted when the predetermined number is reached. In this case, the period from the first activation until the predetermined number is reached is the automatic registration period. In addition to this, the automatic registration period starts, for example, when instructed by the user via the operation unit 24, and ends when the identification information (owner information) of one electronic device is automatically registered according to the connection. A period or the like may be applied. By managing the automatic registration period, the user can restrict the electronic devices that transmit the captured images of the imaging unit 26 to preparation.

  The battery 46 is a power source for supplying power to each component (computer main body 21 and display unit 22) of the desk-top video phone 20. The battery 46 is configured to be rechargeable by receiving power supply from an external power source (commercial power source or the like) via an AC adapter. The tabletop videophone 20 mainly uses the battery 46 as a driving power source during normal use.

  The remaining power of the battery 46 is monitored by the main control unit 47, for example, by monitoring the output of a voltage detection circuit that detects the voltage output from the battery 46. When the remaining amount of power of the battery 46 becomes a predetermined value or less, this is suggested to a device (hereinafter referred to as a permitted device) having identification information (owner information) registered in the permitted device database 45 by the main control unit 47. Notification is sent, or an icon indicating that is displayed on the display unit of the permitted device.

  The main control unit 47 is constituted by a storage medium such as a CPU, RAM, and ROM, and controls the processing operation of the desktop videophone 20 according to a program stored in the storage medium.

  The CPU of the main control unit 47 executes programs such as an operating system, a protocol control program, a video call communication application program, a mail communication application program, and a camera driver program stored in a storage medium such as a ROM, and the execution of these programs. Data required for loading is loaded into the RAM, and according to these programs, at least identification information (owner information) specific to the mobile phone 10 used for authentication when data is transmitted / received to / from the mobile phone 10 is sent to the permitted device database 45. Executes automatic registration processing according to the connection.

  The RAM of the main control unit 47 provides a work area for temporarily storing programs and data executed by the CPU.

  The storage medium such as the ROM of the main control unit 47 stores a startup program for the desktop videophone 20 and various data necessary for executing these programs.

  FIG. 4 is a schematic block diagram illustrating a configuration example of a function realization unit by the CPU of the main control unit 35 of the mobile phone 10. In addition, this function realization part may be comprised by hardware logics, such as a circuit, without using CPU.

  As shown in FIG. 4, the CPU of the main control unit 35 performs at least an OBEX server unit 51, an identification information transmission unit 52, an image transmission request unit 53, and a captured image acquisition according to a program stored in a storage medium such as a ROM. Functions as a unit 54, a display control unit 55, a call request unit 56, a battery information reception unit 57, and a camera operation signal transmission unit 58.

This is because, according to the specification, OBEX cannot extract and send only identification information (owner information) from the phone book data. The file exchange protocol is not limited to OBEX, and other protocols such as a proprietary protocol, SyncML, and Active Sync may be used. For example, when a protocol capable of transmitting and receiving only identification information (owner information) is used as a file exchange protocol with the desktop videophone 20, the identification information transmitting unit 52 only needs to transmit identification information (owner information).

  When the image transmission request unit 53 makes an image transmission request by data communication to the desktop videophone 20 via the base station 30, the identification information transmission unit 52 sends the identification information to the desktop videophone 20. (Including at least information on the MSISDN of the mobile phone 10 and the e-mail address of the owner of the mobile phone 10).

  When the call request unit 56 issues a call request (outgoing) to the desktop videophone 20 via the base station 30, the identification information transmission unit 52 sends identification information (at least to the desktop videophone 20). MSISDN of the mobile phone 10 and information on the e-mail address of the owner of the mobile phone 10 are transmitted).

  Note that the identification information (owner information) transmitted in response to the call request may be MSISDN alone. Generally, a mobile phone that makes a call request is configured to transmit its own MSISDN to a call request destination. When the identification information transmitting unit 52 transmits an e-mail address in addition to the MSISDN, the desk videophone 20 can transmit various information to the e-mail address registered in the permitted device database 45 by e-mail. It becomes like this.

  In the following description, the identification information transmitting unit 52 sends identification information (owner information) including at least the MSISDN of the mobile phone 10 and the e-mail address of the owner of the mobile phone 10 to the tabletop videophone 20 as necessary. An example in the case of transmission will be described.

  The image transmission requesting unit 53 makes a transmission request for the captured image of the imaging unit 26 to the desktop videophone 20 via the base station 30 by data communication other than the videophone call. In the case where the image transmission request unit 53 is used, for example, in addition to the video phone function, the mobile phone 10 is provided with a monitoring function of a captured image of the imaging unit 26 of the desktop video phone 20, and this monitoring function is used. Cases can be considered.

  The captured image acquisition unit 54 receives the captured image of the imaging unit 26 of the desktop video phone 20 from the desktop video phone 20.

  The display control unit 55 causes the display unit 15 to display images including the captured image of the imaging unit 26 received from the captured image acquisition unit 54.

  The call requesting unit 56 makes a voice call request or a videophone call request to the desktop videophone 20 via the base station 30. The videophone call request includes a request for transmission of a photographed image of the imaging unit 26 to the desktop videophone 20.

  The battery information receiving unit 57 receives information from the desktop videophone 20 that the remaining power of the battery 46 of the desktop videophone 20 is equal to or less than a predetermined value.

  Next, in step S7, the identification information extracting unit 64 of the desktop videophone 20 uses the owner information (at least the MSISDN of the mobile phone 10 and the electronic information of the owner of the mobile phone 10) as identification information unique to the mobile phone 10 from the phone book data. (Including email address information).

  Next, in step S <b> 8, the permission identification information registration unit 65 of the desktop video phone 20 registers the identification information (owner information) of the mobile phone 10 in the permitted device database 45.

  Next, in step S <b> 9, the OBEX server unit 51 of the mobile phone 10 and the OBEX client unit 62 of the desk video phone 20 cancel each other's OBEX connection.

  When the mobile phone 10 and the desktop videophone 20 are connected to each other so as to be capable of electrical communication through a wired connection (USB connection or the like) or a wireless connection (BLUETOOTH (registered trademark) or the like), Information can be automatically registered in the permitted device database 45. In this registration process, the user does not need to perform operation input of identification information unique to the mobile phone 10 via the operation unit 13 or 24.

  FIG. 7 shows another procedure when identification information unique to the mobile phone 10 is automatically registered in the permitted device database 45 when the mobile phone 10 and the desktop video phone 20 are connected so as to be capable of electrical communication. It is a flowchart. In FIG. 7, reference numerals with numbers added to S indicate steps in the flowchart. The procedure shown in FIG. 7 is different from the procedure shown in FIG. 6 in that the mobile phone 10 is connected so as to be able to communicate with each other by making a call request to the desktop video phone 20.

  The procedure shown in FIG. 7 is executed for the purpose of registering identification information (owner information) in the permitted device database 45. Therefore, in the procedure shown in FIG. 7, even if a call request is accepted, it is not always necessary to establish a call thereafter. In the following description, an example of a procedure from receiving a call request until registering identification information (owner information) in the permitted device database 45 will be described.

  This procedure is also started when the registration permission unit 61 permits the registration processing for the permitted device database 45 by the permission identification information registration unit 65 to start the automatic registration period.

  First, in step S <b> 11, the call request unit 56 of the mobile phone 10 issues a call request (outgoing call) to the desktop videophone 20 via the base station 30. In the following description, an example in which the call request in step S11 is a videophone call request is shown, but this call request does not have to be a videophone call request, and may be a voice call request.

  When a call request is made by the call request unit 56, the identification information transmission unit 52 sends the identification information (at least the MSISDN of the mobile phone 10 and the e-mail address of the owner of the mobile phone 10) to the desktop video phone 20. Send data containing information).

  Next, in step S 12, the protocol control unit 68 of the desktop videophone 20 receives a videophone call request from the mobile phone 10 and notifies the video call communication unit 69 of an incoming call request signal.

  Next, in step S 13, the call control unit 70 of the video call communication unit 69 is given a call request signal from the protocol control unit 68.

  Next, in step S <b> 14, the identification information receiving unit 63 receives data including identification information (owner information) from the mobile phone 10.

  Next, in step S <b> 15, the permission identification information registration unit 65 registers the identification information (owner information) of the mobile phone 10 in the permitted device database 45.

  According to the above procedure, when a call request is made from the mobile phone 10 to the desktop videophone 20, identification information unique to the mobile phone 10 can be automatically registered in the permitted device database 45. Also in the registration process according to the procedure shown in FIG. 7, as in the procedure shown in FIG. 6, the user does not have to input identification information unique to the mobile phone 10 via the operation unit 13 or 24.

  According to the procedure shown in FIG. 7, even if the mobile phone 10 and the desktop video phone 20 are not close to each other, if they are electrically connected to each other via an electronic network such as a telephone communication network, they are specific to the mobile phone 10. This identification information can be automatically registered in the permitted device database 45, which is very convenient.

  The mobile phone 10 and the desktop video phone 20 according to the present embodiment do not require any operation input by the user, and do not require the prior distribution of the public key, and easily provide identification information unique to the mobile phone 10 on the desktop. It can be registered in the permitted device database 45 of the video phone 20. For this reason, even when the user of the mobile phone 10 changes the terminal and the identification information changes, the re-registration can be performed very easily. For this reason, according to the mobile phone 10 and the desk-top video phone 20, the person to be authenticated can be distinguished accurately and easily.

  FIG. 8 is a flowchart showing a procedure for establishing a videophone call following the procedure shown in FIG. 7 when the call request in step S11 of FIG. 7 is a videophone call request. In FIG. 8, reference numerals with numbers added to S indicate steps in the flowchart. Note that steps equivalent to those in FIG. 7 are denoted by the same reference numerals, and redundant description is omitted.

  After receiving a videophone call request from the mobile phone 10 in steps S11 to S15, the identification information (owner information) of the mobile phone 10 is automatically registered in the permitted device database 45. In step S21, the camera activation unit 71 In response to the instruction from the call control unit 70, the imaging unit 26 is activated. As a result, the imaging unit 26 can capture a video around the desktop videophone 20 and generate a video signal.

  Next, in step S <b> 22, the call control unit 70 gives the protocol control unit 68 permission to respond to the videophone call request from the mobile phone 10.

  Next, in step S <b> 23, the protocol control unit 68 and the call control unit 70 establish a videophone call with the mobile phone 10 via the base station 30. During a videophone call, the protocol control unit 68 and the call control unit 70 multiplex the captured image of the imaging unit 26 and the digital audio signal output from the microphone 27 and transmit them to the mobile phone 10. The captured image acquisition unit 54 of the mobile phone 10 acquires the captured image of the imaging unit 26 by demultiplexing the captured image and sound of the imaging unit 26 from the received signal. The captured image is displayed on the display unit 15 by the display control unit 55. The demultiplexed sound is output from the speaker 16.

  With the above procedure, the identification information (owner information) of the mobile phone 10 can be automatically registered in the permitted device database 45 with a single videophone call request, and a videophone call can be established.

  FIG. 9 shows a procedure in which a captured image of the imaging unit 26 is transmitted from the desktop videophone 20 only in response to a videophone call request of the mobile phone 10 whose identification information (owner information) is already registered in the permitted device database 45. It is a flowchart. In FIG. 9, the code | symbol which attached | subjected the number to S shows each step of a flowchart. Steps equivalent to those in FIG. 8 are denoted by the same reference numerals, and redundant description is omitted. Note that at the start of this procedure, it is assumed that the registration permission unit 61 prohibits the registration processing for the permitted device database 45 by the permission identification information registration unit 65 and the automatic registration period has ended.

  After receiving the videophone call request from the mobile phone 10 in steps S11 to S14 and receiving the identification information (owner information) of the mobile phone 10, the authentication control unit 72 receives the identification information receiving unit 63 in step S31. It is determined whether or not the identified identification information (owner information) is registered in the permitted device database 45. If registered, information to that effect is given from the authentication control unit 72 to the call control unit 70, steps S21 to S23 are executed, and the captured image of the imaging unit 26 is transmitted to the mobile phone 10 to be a videophone. A call is established. On the other hand, if it is not registered, information to that effect is given from the authentication control unit 72 to the call control unit 70, and in order to establish a voice call without transmitting the captured image of the imaging unit 26 to the mobile phone 10, Proceed to step S32.

  In step S <b> 32, the call control unit 70 gives a response permission by voice call to the protocol control unit 68 in response to the videophone call request from the mobile phone 10.

  Next, in step S <b> 33, the protocol control unit 68 and the call control unit 70 establish a voice call with the mobile phone 10 via the base station 30. During a voice call, the protocol control unit 68 and the call control unit 70 transmit the digital audio signal output from the microphone 27 to the mobile phone 10, but do not transmit the captured image of the imaging unit 26.

  If it is determined in step S31 that the identification information (owner information) is not registered in the permitted device database 45, the captured image of the imaging unit 26 may not be transmitted to the mobile phone 10, and the imaging of the imaging unit 26 may be performed. Instead of an image, a predetermined still image or the like (hereinafter referred to as a predetermined still image) stored in advance in the storage unit 44 may be multiplexed with audio and transmitted. In this case, the captured image acquisition unit 54 of the mobile phone 10 acquires a predetermined still image by demultiplexing a predetermined still image and sound from the received signal. This still image is displayed on the display unit 15 by the display control unit 55.

  If it is determined in step S31 that the identification information (owner information) is not registered in the permitted device database 45, a call request including a voice call may be rejected. Also in this case, the captured image of the imaging unit 26 is not transmitted to the mobile phone 10. In this case, steps S32 and S33 are omitted.

  With the above procedure, the desktop videophone 20 does not transmit the captured image of the imaging unit 26 in response to a videophone call request from a device whose identification information (owner information) is not registered in the permitted device database 45. In response to a videophone call request of the mobile phone 10 (permitted device) whose identification information (owner information) has already been registered in the device database 45, the captured image of the imaging unit 26 can be transmitted.

  FIG. 10 is a flowchart showing a procedure for transmitting a captured image of the imaging unit 26 from the desktop videophone 20 only in response to an image transmission request of the mobile phone 10 whose identification information (owner information) is already registered in the permitted device database 45. It is. In FIG. 10, reference numerals with numbers added to S indicate steps in the flowchart. Steps equivalent to those in FIG. 9 are denoted by the same reference numerals, and redundant description is omitted. Similarly to the procedure shown in FIG. 9, at the start of this procedure, the registration permission unit 61 prohibits the registration processing for the permitted device database 45 by the permission identification information registration unit 65, thereby terminating the automatic registration period. It shall be.

  In step S <b> 41, the image transmission request unit 53 of the mobile phone 10 requests the desktop videophone 20 to transmit the captured image of the imaging unit 26 via the base station 30 by data communication that is not a videophone call.

  In step 31, the authentication control unit 72 determines that the identification information (owner information) of the mobile phone 10 is registered in the permitted device database 45. In step S21, the call control unit 70 is instructed and the camera activation unit 71 sets the imaging unit. In step S42, the main control unit 47 of the desk videophone 20 transmits the captured image of the imaging unit 26 to the mobile phone 10 via the base station 30 according to the operating system.

  Next, in step S <b> 43, the captured image acquisition unit 54 of the mobile phone 10 receives the captured image of the imaging unit 26 and gives it to the display control unit 55. The captured image is displayed on the display unit 15 by the display control unit 55.

  With the above procedure, the desk-top videophone 20 takes a picture of the imaging unit 26 in response to an image transmission request by data communication other than a videophone call from a device whose identification information (owner information) is not registered in the permitted device database 45. While the image is not transmitted, the captured image of the imaging unit 26 can be transmitted in response to the image transmission request of the mobile phone 10 whose identification information (owner information) is already registered in the permitted device database 45.

  As shown in FIGS. 9 and 10, the cellular phone 10 and the desk video phone 20 can identify the identification information of a device (permitted device) that permits transmission of a captured image of the imaging unit 26 without a special user input operation. While being able to register easily, the picked-up image of the imaging part 26 can be transmitted only to a permission apparatus. For this reason, an image pickup unit is surely provided to image transmission requesters (including a videophone call requester) that a user such as a wrong caller or a malicious third party does not want to send a captured image of the image pickup unit 26. It is not necessary to send 26 captured images.

  FIG. 11 is a flowchart showing a procedure when a videophone call request is made from the mobile phone 10 to the desktop videophone 20 in the power saving state to establish a videophone call. In FIG. 11, reference numerals with numbers added to S indicate the steps in the flowchart. Steps equivalent to those in FIG. 9 are denoted by the same reference numerals, and redundant description is omitted. Similar to the procedure shown in FIGS. 9 and 10, at the start of this procedure, the registration permission unit 61 prohibits the registration processing for the permitted device database 45 by the permission identification information registration unit 65, thereby increasing the automatic registration period. Assume that it has finished.

  At the start of this procedure, it is assumed that the desktop videophone 20 is in a power saving state.

  In step S11, a call request (call) is made from the call request unit 56 of the mobile phone 10 to the desktop video phone 20 via the base station 30, and a circuit responsible for transmission / reception of radio signals of the base station transmission / reception unit 42 When the call request signal and the identification information are received, the protocol control unit 68 requests the power saving control unit 66 to cancel the power saving state in step S51.

  Next, in step S52, the power saving control unit 66 shifts the operation of the CPU of the main control unit 47 from the intermittent operation to the normal operation state. As a result, the protocol control unit 68 and the video call communication unit 69, which are function implementation units of the CPU, are released from the power saving state (intermittent operation state) and can always operate.

  Then, the captured image of the imaging unit 26 is not transmitted in response to a videophone call request from a device whose identification information (owner information) is not registered in the permitted device database 45 by the procedure from step S21 shown in FIG. On the other hand, in response to a videophone call request of the mobile phone 10 whose identification information (owner information) is already registered in the permitted device database 45, a process of transmitting a captured image of the imaging unit 26 is executed.

  According to the above procedure, even when a videophone call request is made from the mobile phone 10 to the desktop videophone 20 in the power saving state, a device from which identification information (owner information) is not registered in the permitted device database 45 is received. In response to a videophone call request, the captured image of the image pickup unit 26 is not transmitted, while for the videophone call request of the mobile phone 10 whose identification information (owner information) is already registered in the permitted device database 45, the image pickup unit 26 is used. Can be sent.

  This desktop videophone 20 is in a power saving state when waiting for a call request from another electronic device, and for example, a call request from an electronic device in which identification information such as an electronic device owned by the family of the desktop videophone 20 owner is registered. In response to this, a transition is made to the normal operating state. For this reason, according to the mobile phone 10 and the desktop video phone 20, it is possible to greatly reduce the power consumption of the battery 46 that carries the driving power of the desktop video phone 20.

  In FIG. 12, when the remaining amount of power of the battery 46 becomes a predetermined value or less, an e-mail indicating that is sent to a device (permitted device) having identification information (owner information) registered in the permitted device database 45. It is a flowchart which shows the procedure at the time of transmitting. In FIG. 12, the reference numerals with numbers added to S indicate the steps in the flowchart. Similar to the procedure shown in FIGS. 9 to 11, at the start of this procedure, the registration permission unit 61 prohibits the registration processing for the permitted device database 45 by the permission identification information registration unit 65, and thus the automatic registration period ends. Suppose you are. Further, it is assumed that owner information (including an e-mail address) of the mobile phone 10 is registered in the permitted device database 45 in advance.

  First, in step S61, the battery information notification unit 67 determines whether or not the remaining amount of power of the battery 46 is equal to or less than a predetermined value. If it is below the predetermined value, the process proceeds to step S62. On the other hand, if it is greater than the predetermined value, the battery information notification unit 67 continues to monitor the remaining power of the battery 46.

  Next, in step S <b> 62, the battery information notification unit 67 gives information indicating that the remaining power of the battery 46 is equal to or less than a predetermined value to the notification address acquisition unit 74.

  Next, in step S <b> 63, the notification address acquisition unit 74 acquires an e-mail address registered in the permitted device database 45 and gives it to the notification mail generation unit 75. This e-mail address includes the e-mail address of the mobile phone 10.

  Next, in step S <b> 64, the notification mail generation unit 75 generates an email indicating that the remaining power of the battery 46 is equal to or less than a predetermined value. The e-mail address is the e-mail address received from the notification address acquisition unit 74.

  Next, in step S <b> 65, the mail transmission instruction unit 76 gives the protocol control unit 68 a transmission request for the electronic mail generated by the notification mail generation unit 75.

  Next, in step S <b> 66, the protocol control unit 68 and the mail transmission instruction unit 76 transmit an e-mail to the permitted device including the mobile phone 10 via the base station 30.

  Next, in step S <b> 67, the battery information receiving unit 57 of the mobile phone 10 receives this e-mail and displays it on the display unit 15.

  By the above procedure, when the remaining power of the battery 46 falls below a predetermined value, an e-mail indicating that fact is transmitted to a device having identification information (owner information) registered in the permitted device database 45. Can do.

  The procedure shown in FIG. 12 shows an example in which information indicating that the remaining amount of power of the battery 46 of the desktop videophone 20 is equal to or less than a predetermined value is given to a permitting device such as the mobile phone 10 via e-mail. However, if information indicating that the remaining amount of power of the battery 46 is equal to or less than a predetermined value can be notified, the table videophone 20 is not limited to an e-mail. For example, the desktop videophone 20 displays an icon indicating the information on the display unit of the permitted device. You may make it display or generate the sound which suggests that through the speaker of permission apparatus.

  According to the mobile phone 10 and the desktop videophone 20, all the users of the permitted devices can share information indicating that the remaining power of the battery 46 is equal to or less than a predetermined value. For this reason, if the user of the cellular phone 10 does not respond to the call request, the cause of the user of the desktop video phone 20 may be the cause of the inconvenience of the user of the desktop video phone 20, or simply the battery 46 of the desktop video phone 20 It is possible to easily determine whether the remaining amount of power is insufficient or not. For example, when the user of the desktop videophone 20 is an elderly person living alone and the user of the mobile phone 10 is a family member of the mobile phone 10, the user of the mobile phone 10 is not satisfied with the remaining power of the battery 46 of the desktop videophone 20. When the desk-top video phone 20 does not respond to the call request, there is no need to worry about it.

  FIG. 13 shows a case where a videophone call between the mobile phone 10 and the desktop videophone 20 is established, and the user of the mobile phone 10 confirms a captured image of the imaging unit 26 of the desktop videophone 20 from the mobile phone 10. It is a flowchart which shows the procedure at the time of the imaging part 26 being operated. In FIG. 13, reference numerals with numbers added to S indicate steps of the flowchart.

  This procedure starts when the mobile phone 10 is an authorized device for the desktop videophone 20 and a videophone call between the mobile phone 10 and the desktop videophone 20 is established.
