The telephone number display area 506 is an area in which the telephone number of the other party of the call input by pushing the handset operation input means 305 of the handset 30 when the user tries to make a call is displayed. The phone book icon 507 is an icon for making settings related to the phone number lists of a plurality of call partners registered in the parent device 10 by the user. When the user touches and inputs the phone book icon 507, although not shown, a phone number list is displayed so that various settings such as selecting a party to call and adding / deleting a phone number can be performed. . The call icon 509 is an icon for a user to make a call to the telephone number displayed in the telephone number display area 506. When the user touches the call icon 509, the user can make a call to the phone number displayed in the phone number display area 506. When the other party receives a call, the user can make a voice call with the other party via the telephone line 20.

  The call setting icon 508 is an icon for setting various conditions related to a call. When the user touches and inputs a call setting icon 508, the screen switches to a submenu screen related to call setting as shown in FIG. In the submenu screen of FIG. 9, a return icon 510, a recording icon 511, a hold icon 512, a low volume icon 513, a high volume icon 514, a low pitch icon 515, and a high pitch icon 516 are displayed. The return icon 510 is an icon for returning to the submenu screen shown in FIG. The recording icon 511 is an icon for recording a conversation during a call. When the user touches and inputs the recording icon 511 during a call, the conversation during the call can be stored as voice information. Since the audio information storage method here is a function equivalent to the recording function installed in a conventional general-purpose telephone, detailed description thereof is omitted. The hold icon 512 is an icon for temporarily waiting the other party during a call. When the user touches and puts the hold icon 512 during a call with the other party, the user can send a hold sound set in advance to the other party and put it on hold. Since the method for setting the hold state here is a function equivalent to the hold function installed in a conventional general-purpose telephone, detailed description thereof is omitted.

  Next, a small volume icon 513 and a large volume icon 514 are icons for adjusting the volume of the voice information of the other party in the call. When the user wants to reduce the volume of the voice information of the other party during the call, the user inputs a small volume icon 513, and when the user wants to increase the volume, the high volume icon 514 is touch-input. The volume can be adjusted. A volume level meter 517 is displayed so that the set volume level can be confirmed. Moreover, the low pitch icon 515 and the high pitch icon 516 are icons for adjusting the pitch of the voice information of the other party during the call. If the user wants to lower the pitch of the other party's voice information during a call, touch the low pitch icon 515, and if he wants to increase the pitch, touch the high pitch icon 516 to enter the desired value. It can be adjusted to the pitch. A pitch level meter 518 is displayed so that the set pitch level can be confirmed. In the above description, it has been described that the function of the parent device 10 corresponding to each icon can be set by the user touch-inputting the various icons. The setting of the function related to the call while the user is in a call can be set only to the user who satisfies the predetermined condition.

  Below, the main process performed with the main | base station 10 of this embodiment is demonstrated, referring FIGS. The main processing shown in FIG. 10 is processing executed by the CPU 101 in accordance with a program stored in the ROM 102 of the parent device 10.

  The main process shown in FIG. 10 is started when the power of the parent device 10 is turned on. First, the CPU 101 determines whether there has been an instruction to make or receive a call (S400). Specifically, in the process of step S400, the user makes a call input or an incoming call by touch-inputting the call icon 509 of the base unit 10, or by operating the handset operation input means of the handset 30. It is determined whether the instruction operation has been performed. In the process of step S400, when the CPU 101 determines that there is no call origination / incoming call instruction (S400: NO), the process of step S400 is repeatedly executed again.

  In the process of step S400, when the CPU 101 determines that there has been a call / incoming call instruction (S400: YES), it executes a call start process (S401). In the process of step S401, the user and the other party who is calling or receiving are able to make a voice call using the microphone 303 or the speaker 304 of the handset 30. Specifically, the user's voice is acquired as voice information from the microphone 303 of the slave unit 30, and the slave unit communication unit 340, the slave unit communication unit 140 of the master unit 10, and the communication unit 150 via the telephone line 20, The acquired voice information is transmitted to the call terminal device of the call partner. Also, the voice information of the other party is received from the telephone line 20 by the communication unit 150 of the base unit 10, transmitted from the slave unit communication unit 140 to the slave unit communication unit 340 of the slave unit 30, and the other party's voice information from the speaker 304. Is output.

  Next, after the process of step S401, the CPU 101 determines whether or not a touch operation has been performed (S402). Specifically, in the process of step S402, it is determined based on the contact detection result of the operation input unit 114 whether or not a touch input operation has been performed on the display unit 12 of the base unit 10 while the user is in a call. is doing. If the CPU 101 determines in the process of step S402 that a touch operation has been performed (S402: YES), it is then determined whether the operation is related to a call (S403). The operation related to the call here is, for example, an operation in which the user performs touch input on the call setting icon 502 on the submenu screen shown in FIG. 8 or each setting icon on the submenu screen shown in FIG. . If the CPU 101 determines in step S403 that the operation is not related to a call (S403: NO), the CPU 101 executes a process corresponding to an operation other than the touch input (S407). In the process of step S407, specifically, it is determined that, for example, the main body setting icon 501, the photo icon 503, the music icon 504, etc. on the menu screen of FIG. After that, the operation corresponding to the touch input icon is executed.

  In the process of step S403, when the CPU 101 determines that the operation is related to a call (S403: YES), it next determines whether an electrical signal is detected (S404). Here, the process of step S404 will be described in detail with reference to FIG.

  FIG. 11 shows a state in which the user 70 is touch-inputting to the display means 12 of the parent device 10 installed on the desk while holding the child device 30 by hand and talking. After the call is started in step S401, a predetermined electrical signal is transmitted from the electrical signal transmission unit 306 of the slave unit 30 at a predetermined interval (for example, 20 mS interval). Therefore, since the electric signal transmitting means 306 (see FIG. 2) arranged on the back surface of the slave unit 30 is in contact with the hand of the user 70, the electric signal is transmitted to the human body of the user 70. Communicated. When the user 70 performs a touch input to the display unit 12 of the parent device 10, the electric signal transmitted from the electric signal transmission unit 306 of the child device 30 is transmitted to the parent device via the hand of the user 70 who has performed the touch input. 10 electric signal receiving means 115. In the process of step S <b> 404, the CPU 101 determines whether the electrical signal receiving unit 115 has detected an electrical signal. Here, when detecting an electrical signal, in order to determine whether the electrical signal is transmitted from the electrical signal transmission means 306 of the slave unit 30 or to remove a noise signal or the like, for example, the detected electrical signal is A threshold value may be provided for determining whether the frequency is a predetermined frequency set in the slave unit 30 or greater than a predetermined voltage value, and the threshold value is compared with the threshold value.

  If the CPU 101 determines in the process of step S404 that an electric signal has been detected (S404: YES), it next executes a process corresponding to the operation related to the telephone call input in the process of step S402 (S405). In the process of step S405, when the user touches and inputs the call setting 508 on the submenu screen shown in FIG. 8, and selects and touches the icon of each function in the submenu screen shown in FIG. The base unit 10 executes a function process corresponding to the touch-input icon. For example, when the user touch-inputs the recording icon 511, the CPU 101 of the parent device 10 executes a process of storing voice information of the user and the other party. When the hold icon 512 is touch-inputted, a process is executed in which a hold sound for making the call partner wait for a call is sent to the call terminal device of the call partner. Further, when a touch input is made on the low volume icon 513 or the high volume icon 514, a process of adjusting the volume of the voice information of the other party on the call is executed. In addition, when touch input is performed on the low pitch icon 515 or the high pitch icon 516, a process of adjusting the pitch of the voice information of the call partner is executed. Accordingly, the user who is holding the handset 30 and is making a call can operate various settings related to the call as described above during the call.

  In the process of step S404, when the CPU 101 determines that the electrical signal from the slave unit 30 is not detected (S404: NO), it displays an error (S406). In the process of step S406, specifically, since an electric signal is not detected from the hand of the user who touch-inputs the function icon related to the call, the user who has made the touch input holds the handset 30 and makes a call. It is determined that the user is other than the user who is performing the operation, and the function corresponding to the touch-input icon is disabled. Then, an error display is displayed on the display means 12 indicating that the function icon relating to the call input by the other person is invalid.

  After the process of step S405, step S406, or step S407 described above, the CPU 101 determines whether there is a call end instruction (S408). Specifically, the process of step S408 detects whether the user who is holding the handset 30 and is talking is pressing a push button for disconnecting the call included in the handset operation input means 305, for example. Judge by. Alternatively, if the call icon 509 shown in FIG. 8 is changed to a disconnect icon (not shown) for disconnecting the call when the call is in progress, the disconnect icon of the base unit 10 can be displayed by the user. Judgment can also be made by touch input. If the CPU 101 determines in the process of step S408 that there is no call termination instruction (S408: NO), it returns to the process of step S402 and repeats the subsequent processes. If the CPU 101 determines in the process of step S408 that there has been a call termination instruction (S408: YES), the process ends.

  Therefore, by executing the main process described above, only the user who holds the handset 30 and makes a call can perform operations related to the call of the base unit 10. Therefore, the user who makes a call can prevent the problem that the operation related to the call to the base unit 10 is inputted by another person and the call is disturbed.

  Hereinafter, as a modification of the present embodiment, a main process 2 executed by the parent device 10 will be described with reference to FIG. The main process 2 shown in FIG. 12 is a process executed by the CPU 101 in accordance with a program stored in the ROM 102 of the parent device 10.

  The main process 2 shown in FIG. 12 is started when the power of the parent device 10 is turned on. However, steps S600 to S603 are the same as steps S400 to S403 of the main process described with reference to FIG. If the CPU 101 determines YES in the process of step S603 (S603: YES), a slave unit holder determination process is executed (S604).

  Therefore, the handset owner determination process will be described with reference to FIG. First, the CPU 101 executes processing for acquiring imaging information (S701). Specifically, the imaging unit 116 of the parent device 10 is driven, and processing for acquiring imaging information of the user who is operating the parent device 10 is executed. Next, the CPU 101 determines whether or not a human face can be detected from the imaging information acquired in the process of step S701 (S702). The face detection process in the process of step S702 uses a conventionally proposed technique. For example, for example, contour information is extracted from the acquired imaging information based on color distribution information, luminance information, etc., and the extracted contour information and a person registered and stored in the feature image information storage area 242 in advance are stored. A method of matching the feature image corresponding to the shape of the eyes, nose, and mouth with a pattern matching method or the like may be used.

  If the CPU 101 determines in step S702 that face detection has failed (S702: NO), the CPU 103 stores in the RAM 103 a determination that the operation in step S602 (FIG. 12) is not the operation of the child device holder. (S706). In the process of step S702, when the CPU 101 determines that a face has been detected (S702: YES), it next determines whether a child device image has been detected (S703). Specifically, contour information extracted based on color distribution information, luminance information, and the like from the acquired imaging information and registered in the feature image information storage area 242 in advance using the same conventional method as the face detection processing in step S702. The feature image information corresponding to the shape and color of the slave unit 30 is collated by a pattern matching method or the like. If the CPU 101 determines in the process of step S703 that no handset image information is detected (S703: NO), the process proceeds to the process of step S706 described above.

  If it is determined in step S703 that the CPU 101 has detected the child device image information (S703: YES), the hand input by touching in step S602 (FIG. 12) is the child device holder. It is determined whether or not it is a hand (S704). Specifically, the process of step S704 is performed by detecting the contour information of the human body shape including the detected face image information based on the contour information extracted from the imaging information in the process of step S702. It is determined whether the contour information of the human body shape is a shape that is touch-inputted to the display unit 12 of the parent device 10. This determination is made in advance by registering and storing the feature image information of the human body shape in a state in which touch input is manually performed on the display unit 12 of the master unit 10 as shown in FIG. 11 in the feature image information storage area 242. In addition, it may be determined by comparing the contour information of the human body shape extracted from the imaging information acquired by the imaging unit 116 with the pattern matching method or the like.

  If the CPU 101 determines in step S704 that the touched hand is not the hand of the child device holder (S704: NO), the process proceeds to step S706 described above. If the CPU 101 determines in step S704 that the touched hand is the hand of the child device holder (S704: YES), the operation in step S602 (FIG. 12) is performed by the child device holder. Is stored in the RAM 103 (S705). Then, after the process of step S705 or step S706, the present process is terminated.

  Returning to the description of FIG. 12, after the process of step S <b> 604, the CPU 101 next determines whether the operation is performed by the child device holder (S <b> 605). In the process of step S605, the determination result determined in the process of step S604 is acquired from the RAM 103, and it is determined whether or not the operation is performed by the child device holder. In the process of step S605, if the CPU 101 determines that the operation is not performed by the child device holder (S605: NO), that is, if it is determined that the process of S706 (FIG. 13) has been executed, an error display process is executed (S607). ). In the process of step S605, if the CPU 101 determines that the operation is a child device holder operation (S605: YES), that is, if it is determined that the process of S705 has been executed, the touch input is performed in the process of step S602. An operation related to a call is executed (S606). Further, the processing in step S606 is the same as the processing in step 405 in FIG. 10, and the processing in step S607 is the same as the processing in step 406 in FIG. In addition, the processes in steps S608 and S609 are the same as the processes in steps S407 and S408 in FIG.

  Therefore, by executing the main process 2 described above, the user who holds the handset 30 and makes a call is identified based on the captured image information obtained by capturing the user, and is identified during the call. Only the user can perform operations related to the call of the base unit 10. Therefore, the user who holds the handset 30 and makes a call can prevent the problem that the operation related to the call to the base unit 10 is inputted by another person and the call is disturbed.

  It should be noted that the configuration and processing shown in the present embodiment described above are examples, and it goes without saying that various modifications are possible. For example, as the functions installed in the base unit 10 of the present embodiment, the functions corresponding to the icons displayed on the menu screen and the sub menu screen as shown in FIGS. It is not a thing. For example, as other functions, an answering machine function, a nuisance call answering function, a transfer function, a call charge display function, and the like that are installed in a general telephone may be installed.

  In addition, in the processing of step S406 in FIG. 10 and step S607 in FIG. 12, an error display is displayed when an operation related to the call is performed by a person other than the user who holds the handset 30 and is talking. Although described, it is not limited to this. For example, the function related to the operated call may be simply not executed by the base unit 10 without displaying an error.
