[0009] [Embodiment 1] An embodiment of the present invention will be described below with reference to the drawings. Note that, although the following description will be made based on an example in which the terminal device according to the present invention is a telephone 1 (a cordless telephone handset), the present invention is not limited to this example and can also be applied to, for example, an intercom with a camera and a face recognition function.

[0010] <Phone Overview> FIG. 1 is a front view showing an example of a telephone 1, and FIG. 2 is a perspective view showing an example of the appearance of the telephone 1. As shown in FIG.

[0011] As shown in FIGS. 1 and 2, a telephone 1 (terminal device) includes, for example, an operation unit 2, a display unit 3, a microphone 4, and a speaker 5 (see FIG. 3).

[0012] Operation unit 2 accepts input operations from the user and is configured, for example, with hardware keys. Operation unit 2 includes a call button 21 as a first operation unit, a nuisance stop button 22 as a second operation unit, and various operation buttons 23. Details of operation unit 2 will be described later.

[0013] The display unit 3 displays various types of information and includes a first display unit 31 and a second display unit 32. Details of the display unit 3 will be described later.

[0014] The microphone 4 includes a first microphone 41 and a second microphone 42. The first microphone 41 picks up the voice spoken by the user, converts it into a voice signal by the control unit 10, and transmits it to the other party's telephone via the telephone line network 9 (see FIG. 3). The second microphone 42 is a microphone for voice recognition, and picks up the voice spoken by the user and sends it to a voice recognition unit (not shown). This allows the user to operate the telephone 1 by voice.

[0015] The speaker 5 is provided, for example, on the rear surface of the telephone 1, and outputs ring tones and sounds.

[0016] The telephone 1 has a plurality of states. The plurality of states includes, for example, at least three states. The plurality of states includes, for example, a first incoming call state from a safe party (first party), a second incoming call state from an unsafe party (second party), and a standby state. The first incoming call state is a first state associated with a safe party (first party). The second incoming call state is a second state associated with an unsafe party (second party). The standby state is a third state not associated with any party.

[0017] The display unit 3 indicates which of a plurality of states the telephone 1 is in. The operation unit 2 allows the user to perform an operation according to the state of the telephone 1 (accepts an operation from the user).

[0018] (Call button and first display) When a call comes in, the user can operate the call button 21 to put the phone into a call state. The user can also operate the call button 21 to end a call that is currently in progress.

[0019] The first display unit 31 includes a first light emitting unit 311. The first light emitting unit 311 is configured by, for example, an LED or the like. The light emitting manner of the first light emitting unit 311 changes according to the multiple states of the telephone 1.

[0020] First light-emitting unit 311 flashes when there is an incoming call, to notify the user of the incoming call status of telephone set 1. First light-emitting unit 311 flashes, for example, green when there is an incoming call from a safe party, and flashes red when there is an incoming call from an unsafe party.

[0021] In this way, first light-emitting unit 311 changes the flashing color depending on the caller, allowing the user to check the flashing color of first light-emitting unit 311 and determine whether or not to answer the call.

[0022] The first light-emitting unit 311 may be configured to light up green when in a call with a safe party, light up red when in a call with an unsafe party, and not light up when in standby mode.

[0023] Furthermore, first light-emitting unit 311 is not limited to this, and may, for example, change the manner of light emission, such as the blinking speed or blinking pattern, depending on the caller, to indicate whether the call is from a safe party. Note that telephone 1 may change the ringtone in response to changes in the manner of light emission of first light-emitting unit 311.

[0024] The first display unit 31 is configured integrally with the call button 21. Here, "configured integrally" includes not only a case where they are structurally integrated, but also a case where the display area of ​​the first display unit 31 shares at least a part of the operation area of ​​the call button 21.

[0025] The call button 21 includes, for example, a translucent dome-shaped key top portion 211, and the user can operate the call button 21 by pressing the key top portion 211.

[0026] The call button 21 is arranged so that the key top portion 211 covers the first light emitting portion 311 of the first display portion 31. The user can visually recognize the blinking of the first light emitting portion 311 through the key top portion 211. The user can press the display area of ​​the blinking first light emitting portion 311 from above to press the key top portion 211 and operate the call button 21.

[0027] In this way, the first light emitting portion 311 is configured integrally with the call button 21, and is arranged so that the display area of ​​the first light emitting portion 311 shares at least a part of the operation area of ​​the call button 21.

[0028] The first light-emitting unit 311 flashes green when the telephone 1 is receiving an incoming call from a safe party. The user visually confirms through the key top unit 211 that the first light-emitting unit 311 is flashing green and confirms that the incoming call is from a safe party. The user can operate the call button 21 by pressing the display area of ​​the first light-emitting unit 311 that is flashing green from above. This allows the user to intuitively operate the call button 21 without having to shift their gaze or make a mistake in selecting one of the multiple operation buttons.

[0029] (nuisance stop button and second display area) Nuisance stop button 22 is a button that can be operated by the user to automatically hang up the call after an automatic answer when telephone set 1 is receiving an incoming call from an unsafe caller.

[0030] The second display unit 32 includes a second light emitting unit 321. The second light emitting unit 321 is configured by, for example, an LED or the like. The light emitting manner of the second light emitting unit 321 changes according to the multiple states of the telephone 1.

[0031] When telephone 1 is receiving an incoming call from an unsafe party, second light-emitting unit 321 flashes red together with first light-emitting unit 311. Second light-emitting unit 321 may be configured not to emit light when receiving an incoming call from a safe party, when in conversation, or when in standby mode. Second light-emitting unit 321 is configured integrally with nuisance stop button 22.

[0032] The nuisance stop button 22 has a translucent key top portion 221, and the nuisance stop button 22 can be operated by pressing the key top portion 221.

[0033] Nuisance stop button 22 is arranged such that key top portion 221 covers second light emitting portion 321 of second display portion 32. A user can visually recognize the blinking of second light emitting portion 321 through key top portion 221. A user can press key top portion 221 and operate nuisance stop button 22 by pressing the display area of ​​blinking second light emitting portion 321 from above.

[0034] In this way, the second light-emitting unit 321 is configured integrally with the nuisance stop button 22, and is arranged so that the display area of ​​the second light-emitting unit 321 shares at least a portion of the operation area of ​​the nuisance stop button 22.

[0035] When an incoming call from an unsafe party is detected, first light-emitting unit 311 and second light-emitting unit 321 flash in red. The user visually confirms through key top units 211 and 221 that first light-emitting unit 311 and second light-emitting unit 321 are flashing in red, and confirms that the incoming call is from an unsafe party.

[0036] If the user decides not to answer the call, the user can operate the nuisance stop button 22 by pressing from above the display area of ​​the second light-emitting portion 321 that flashes in red.

[0037] On the other hand, if the user decides to answer the call, the call button 21 can be operated by pressing from above the display area of ​​the first light-emitting portion 311 that flashes in red.

[0038] In telephone 1, call button 21 is configured integrally with first display unit 31, which indicates the status of telephone 1. Therefore, call button 21, which is used to start a call, lights up in different ways depending on whether the incoming call is from a safe caller or an unsafe caller. The same is true for nuisance stop button 22 and second display unit 32. This allows the user to intuitively operate call button 21 or nuisance stop button 22 when a call comes in, without having to shift their gaze or make a mistake in selecting one of the multiple operation buttons.

[0039] In the above example, the example has been described in which first light-emitting unit 311 and second light-emitting unit 321 are provided and, when an incoming call is from an unsafe party, first light-emitting unit 311 and second light-emitting unit 321 flash. However, the present invention is not limited to this, and, for example, the example may be configured in such a way that only first light-emitting unit 311 is provided and, when an incoming call is from an unsafe party, first light-emitting unit 311 flashes.

[0040] <Main components of the telephone> The configuration of the telephone 1 of this embodiment will be described with reference to Fig. 3. Fig. 3 is a block diagram showing an example of the configuration of the main parts of the telephone 1.

[0041] 3, telephone 1 includes an operation unit 2, a display unit 3, a microphone 4, a speaker 5, a control unit 10, and a memory unit 50. The operation unit 2, the display unit 3, the microphone 4, and the speaker 5 have already been described in detail, so the description will not be repeated.

[0042] The control unit 10 controls each unit of the telephone set 1 and includes a communication control unit 11, a called number acquisition unit 12, a nuisance number determination unit 13, and an output control unit 14. The output control unit 14 includes a display control unit 141 and a sound output control unit 142.

[0043] The storage unit 50 stores various data used by the control unit 10, and is configured to include a telephone directory 51 and ring tone data 52.

[0044] The telephone directory 51 is a list that associates telephone numbers with information indicating the users of the telephones having those telephone numbers. As an example, the telephone directory 51 is realized as a database that stores telephone numbers in association with character strings indicating the names of the users.

[0045] Specifically, the telephone directory 51 is a database that stores the telephone numbers of parties that the user has permitted to communicate with. Therefore, parties with telephone numbers stored in the telephone directory 51 are likely to be safe parties. On the other hand, parties with telephone numbers not stored in the telephone directory 51 and parties with withheld telephone numbers are likely to be unsafe parties.

[0046] The telephone book 51 may be stored in the storage unit 50 of the handset of the cordless telephone, which is the telephone 1 of this embodiment, or may be stored in the storage unit of the base unit. It may also be stored in an external storage device other than the above.

[0047] The ringtone data 52 is data of a ringtone that notifies the user of an incoming call, and is stored in the storage unit 50.

[0048] The communication control unit 11 controls communication between the telephone 1 and an external device (for example, another telephone). When there is an incoming call from another telephone, the communication control unit 11 notifies the called number acquisition unit 12 to that effect.

[0049] The called number acquisition unit 12 acquires the telephone number of the other telephone that received the call (the call source) (hereinafter referred to as the “called telephone number”), and sends the acquired called telephone number to the nuisance number determination unit 13.

[0050] When the nuisance number determination unit 13 acquires the incoming phone number, it refers to the telephone directory 51 and determines whether the incoming phone number is stored in the telephone directory 51. If the nuisance number determination unit 13 determines that the incoming phone number is stored in the telephone directory 51, it determines that the caller is safe.

[0051] On the other hand, if it is determined that the caller is not stored in the telephone directory 51 or that the caller's phone number is withheld, it is determined that the caller is not safe. The nuisance number determination unit 13 notifies the output control unit 14 of the result of the determination. In this way, the nuisance number determination unit 13 (state determination unit) determines which of multiple states the telephone 1 is in. The output control unit 14 controls the display unit 3 via the display control unit 141 based on the result of the determination by the nuisance number determination unit 13. Specifically, if the nuisance number determination unit 13 determines that the caller is safe, the output control unit 14 causes the first light-emitting unit 311 to flash green.

[0052] On the other hand, if nuisance number determination unit 13 determines that the caller is an unsafe party, output control unit 14 causes first light-emitting unit 311 and second light-emitting unit 321 to flash in red.

[0053] When an incoming call is received, sound output control unit 142 reads out predetermined ringtone data from ringtone data 52 and outputs it from speaker 5. Sound output control unit 142 may change the ringtone based on the result of the determination by nuisance number determination unit 13. This allows the user to confirm whether the incoming call is from a safe party not only by the flashing color of call button 21 and nuisance stop button 22 but also by the ringtone.

[0054] <Processing flow> An example of the flow of processing executed by the control unit 10 will be described with reference to Fig. 4. Fig. 4 is a flowchart showing an example of the flow of processing executed by the control unit 10.

[0055] First, the communication control unit 11 detects that there is an incoming call from another telephone (S1). The called number acquisition unit 12 acquires the called telephone number and notifies the nuisance number determination unit 13 of the acquired telephone number.

[0056] The nuisance number determination unit 13 determines whether the acquired incoming phone number is stored in the telephone directory 51. If the nuisance number determination unit 13 determines that the incoming phone number is not stored in the telephone directory 51 and that the caller is an unsafe party (NO in S2), it notifies the output control unit 14 of this fact.

[0057] Upon receiving the notification, the output control unit 14 causes the first light-emitting unit 311 and the second light-emitting unit 321 to blink in red (S3).

[0058] The control unit 10 determines whether or not it has accepted an operation of the call button 21 by the user. If the control unit 10 determines that the operation has been accepted (YES in S4), the control unit 10 puts the telephone 1 into a call state. At this time, the output control unit 14 lights up the first light-emitting unit 311 and the second light-emitting unit 321 in red (S10). This allows the user to know that they are currently in a call with an unsafe party.

[0059] On the other hand, when the control unit 10 determines that the operation of the call button 21 has not been accepted (NO in S4), it determines whether or not the operation of the nuisance stop button 22 by the user has been accepted.

[0060] When the control unit 10 determines that it has accepted the operation of the nuisance stop button 22 (YES in S5), it responds automatically with a predetermined voice, and then automatically disconnects the communication via the communication control unit 11 (S6). At this time, the output control unit 14 lights up the first light-emitting unit 311 and the second light-emitting unit 321 in red during the automatic response, and then turns them off when the communication is disconnected.

[0061] On the other hand, if the control unit 10 determines that the operation of the nuisance stop button 22 has not been accepted (NO in S5), the process returns to S4.

[0062] Returning to S2, if nuisance number determination unit 13 determines that the incoming telephone number is stored in telephone directory 51 and that the caller is a safe party (YES in S2), it notifies output control unit 14 to that effect.

[0063] Upon receiving the notification, the output control unit 14 causes the first light emitting unit 311 to blink in green and causes the second light emitting unit 321 not to emit light (S7).

[0064] The control unit 10 determines whether or not it has accepted the user's operation of the call button 21. If it is determined that it has been accepted (YES in S8), the control unit 10 puts the telephone 1 into a call state. At this time, the output control unit 14 lights up the first light-emitting unit 311 in green (S9). This allows the user to know that they are currently in a call with a safe party.

[0065] On the other hand, if the control unit 10 determines that the operation of the call button 21 has not been accepted (NO in S8), the control unit 10 repeats the determination in S8.

[0066] [Embodiment 2] Other embodiments of the present invention will be described below. For ease of explanation, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0067] FIG. 5 is a front view showing an example of a telephone 1 according to a second embodiment. As shown in FIG. 5, the telephone 1 includes a touch panel 6 (display unit). The call button 21 and the nuisance stop button 22 are realized as a display area for at least one of characters and images displayed on the touch panel 6. The touch panel 6 changes the display content (display modes of the call button 21 and the nuisance stop button 22) according to a plurality of states. The call button 21 and the nuisance stop button 22 are operated by the user's touch operation on this display area.

[0068] The display areas of the call button 21 and the nuisance stop button 22 are configured integrally with the respective operation areas, and each display area shares at least a part of each operation area.

[0069] When a call is coming from a safe party, the call button 21 may be displayed in green, for example, and may also display text or an image indicating that the party is safe. The user can operate the call button 21 by touching the display area of ​​the call button 21 displayed in green. This allows the user to intuitively operate the call button 21 without shifting their gaze or making a wrong selection.

[0070] When an incoming call is coming from an unsafe caller, the call button 21 and the nuisance stop button 22 may be displayed in red, for example, and may also display text or an image indicating that the caller is unsafe. The user can operate the call button 21 or the nuisance stop button 22 by touching the display area of ​​the call button 21 or the nuisance stop button 22 displayed in red. This allows the user to intuitively operate the call button 21 or the nuisance stop button 22 without shifting their gaze or making a wrong selection.

[0071] In addition, when in standby mode or in call mode, the call button 21 and the nuisance stop button 22 may be displayed in white or another color.

[0072] In addition, in each of the above embodiments, telephone numbers of parties that the user does not permit to be called may be stored as call-prohibited numbers in the telephone directory 51. In this case, if the incoming telephone number matches any of the call-prohibited numbers, the nuisance number determination unit 13 may operate to determine that the party is not safe.

[0073] [Modification] Although the above description has been given of the case where the terminal device is a telephone, the terminal device may also be an intercom. In this case, the terminal device acquires a facial image of the visitor (the other party) from an outdoor camera instead of a telephone number. If the acquired facial image matches a facial image previously stored in a storage unit, the terminal device may determine that a safe party is visiting. If the acquired facial image does not match a facial image previously stored in a storage unit, the terminal device may determine that an unsafe party is visiting. The multiple states of the terminal device include a state where a safe party is visiting, a state where an unsafe party is visiting, and a standby state. As in the above embodiment, the terminal device may change the display content or light emission mode of a display unit integrated with an operation unit depending on the state.

[0074] [Software implementation example] The functions of telephone 1 (hereinafter referred to as "device") can be realized by a program that causes a computer to function as the device, and a program that causes a computer to function as each control block of the device (particularly each part included in control unit 10).

[0075] In this case, the device includes a computer having at least one control device (e.g., a processor) and at least one storage device (e.g., a memory) as hardware for executing the program. The control device and storage device execute the program, thereby realizing the functions described in each of the above embodiments.

[0076] The program may be non-transitory and may be recorded on one or more computer-readable recording media. The recording media may or may not be included in the device. In the latter case, the program may be supplied to the device via any wired or wireless transmission medium.

[0077] Furthermore, some or all of the functions of the control blocks can be realized by logic circuits. For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of the control blocks can also be realized by, for example, a quantum computer.
