Abstract

A portable terminal, provided with: an earpiece and a mouthpiece used for conversing; an earpiece sensor, provided near the earpiece, for sensing a state in which a human body has come near the earpiece; a mouthpiece sensor, provided near the mouthpiece, for sensing a state in which a human body has come near the mouthpiece; and a control unit for controlling the conversation state on the basis of the sensing result from the earpiece sensor and the sensing result from the mouthpiece sensor. The control unit maintains the conversation state when the earpiece sensor senses that the human body and the earpiece are near each other and the mouthpiece sensor does not sense that the human body and the mouthpiece are near each other, and suppresses output of the sound from the mouthpiece to the conversation partner when the earpiece sensor does not sense that the human body and the earpiece are near each other and the mouthpiece sensor senses that the human body and the mouthpiece are near each other. It is thereby possible to, e.g., prevent the conversation partner from hearing unnecessary sounds.

Description

Portable terminal, method for controlling portable terminal, and non-transitory computer-readable medium

The present invention relates to a portable terminal, a portable terminal control method, and a non-transitory computer-readable medium.

When a telephone call is temporarily interrupted, a method is generally used to prevent sound leakage by covering the microphone with a hand so that the other party does not hear unwanted sounds. . However, such a method may not completely prevent sound leakage from the microphone unit.

For example, Patent Document 1 discloses a mobile phone device capable of controlling audio mute on and mute off with a simple operation as a technique for preventing the other party from listening to unnecessary sounds when a call is interrupted in a telephone. Has been. The mobile phone device according to Patent Document 1 includes a contact detection unit beside the microphone. When the user brings a finger into contact with the contact detection unit, the mobile phone device mutes the sound input from the microphone. When the user releases the finger that has touched the contact detection unit, the sound mute described above is released. Thereby, the user can prevent the other party from listening to unnecessary sounds.

Further, Patent Document 1 discloses a mode in which audio mute is continued even after the user lifts his / her finger from the contact detection unit. In this case, when the user operates a key such as a call key, the audio mute is released.

Further, Patent Documents 2 to 4 describe telephone technologies that provide a sensor for detecting proximity to the ear near the earpiece of the telephone and place the call on hold when the sensor does not detect proximity of the ear. Has been. For example, in the telephone according to Patent Document 2, a sensor is provided in the vicinity of the speaker of the handset. This telephone is configured not to output the voice signal input from the microphone to the other party when the user separates the handset from the ear. That is, the call is set to the hold state. When the user has a handset in contact with his / her ear, the user can make a normal call by outputting a detection signal from the sensor. Even if the sensor is away from the ear for a short time (for example, 2 to 3 seconds), the call state is maintained.

However, the mobile phone described in Patent Document 1 has the following problems. As described above, the user switches on / off the sound mute depending on whether or not the finger is brought into contact with the contact detection unit of the mobile phone. In this case, in the state where the audio mute state is turned on, the hand operation that the user can perform is limited.

Further, in Patent Document 1, there is also a technology in which a user makes a voice mute state by once touching and releasing a finger from the contact detection unit, and the user mutes the voice mute by operating a call key or the like. . However, when a user resumes a call, it is natural that the ear (face) is first brought close to the telephone, and performing a key operation when resuming a call is not a natural operation of the user. Furthermore, if the user operates an unnecessary button, the call may be disconnected.

Further, in the telephones according to Patent Documents 2 to 4, when the user removes his / her ear from the speaker (receiving unit), the call is set to a hold state or the like. However, it is assumed that the user does not intend to put the call on hold and puts the handset away from the ear. In that case, calls are frequently placed on hold.

Patent Document 2 also describes a technique in which a call is held for a short time after the user removes his / her ear from the speaker. However, since the call is held for a short time of about 2 to 3 seconds, the user must perform an operation while paying attention to the time during which the call is put on hold. In such a case, the user may experience discomfort such as frustration.

The present invention has been made in order to solve such problems, and provides a mobile terminal that does not allow the other party to hear unnecessary sounds, a control method for the mobile terminal, and a non-transitory computer-readable medium. Objective.

A speech sensor that detects a state in which a human body is close to the transmitter, and a controller that controls a call state based on a detection result by the receiver sensor and a detection result by the transmitter sensor. Prepare. The control unit continues the call state when the receiver sensor detects the proximity of the human body and the receiver, and the transmitter sensor does not detect the proximity of the human body and the transmitter. When the transmitter sensor does not detect the proximity of the human body and the receiver, and the transmitter sensor detects the proximity of the human body and the transmitter, the transmitter transmits a call to the other party. Suppresses sound output.

The second aspect of the present invention includes a mobile terminal. The portable terminal includes a transmitter unit, a camera unit that captures an image in a videophone, a sensor that detects proximity to a human body, an output of sound from the transmitter unit to a call partner, and a camera unit to a call partner. A control unit that controls output of the video. The control unit has a videophone function that suppresses output of sound from the transmitting unit to the calling party and output of video from the camera unit to the calling party when the sensor detects the proximity of a human body.

Embodiment 1
The mobile terminal according to the present embodiment includes sensors in the vicinity of the reception unit and the transmission unit, and controls the call state based on the detection result of each sensor. Thereby, the portable terminal can control the call state more appropriately, and can prevent the other party from hearing an unnecessary sound. Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an example of the overall configuration of a mobile terminal according to the present embodiment. The mobile terminal 1 according to the present embodiment includes a receiver 2, a transmitter 3, a communication unit 4, a receiver sensor 5 (first sensor), a transmitter sensor 6 (second sensor), and a controller 7. Prepare. The mobile terminal 1 is a mobile terminal that allows a user to make a call, such as a mobile phone, a PHS (Personal Handy-Phone SYSTEM), and a smartphone.

The receiving unit 2 has a speaker or the like, and is a part where the user can hear the voice from the other party during a call. When voice information from the other party is input as an electrical signal from the control unit 7 to the receiver unit 2, the receiver unit 2 converts the electrical signal and outputs it as a voice to the user.

The transmitter 3 has a microphone or the like. When the user speaks toward the transmitting unit 3, the transmitting unit 3 converts the sound into an electrical signal and outputs it to the control unit 7. Although not shown, the transmitter 3 may include an amplifier that amplifies the user's voice signal.

The communication unit 4 includes an antenna, a wireless circuit, and the like, and has a function of performing a call by performing wireless connection to a base station, transmission / reception of wireless information, conversion of an electrical signal, and the like. When the communication unit 4 operates and the mobile terminal 1 is communicating, the communication unit 4 outputs an audio signal or the like from the other party to the control unit 7. In addition, the communication unit 4 converts the user's voice signal output from the control unit 7 (the voice signal spoken by the user toward the transmitter unit 3) and wirelessly transmits the signal to the base station. When the communication unit 4 is operating (the user is talking), the communication unit 4 outputs a signal indicating that the call is in progress to the control unit 7.

The receiver sensor 5 is provided in the vicinity of the receiver 2, and a state where a human body (parts such as ears, fingers, hands, etc.) is in proximity to or in contact with the receiver 2 (hereinafter, both states are collectively referred to as “proximity”). Detect). Here, the reception unit sensor 5 is provided in the vicinity of the reception unit 2 so that it can detect a state in which the user's ear is close to the reception unit 2 during a call. For example, the receiver unit sensor 5 may be provided in the vicinity of the receiver unit 2 within a radius of 10 mm from the receiver unit 2.

When the reception unit sensor 5 detects a state in which a human body is close to the reception unit 2, the reception unit sensor 5 outputs a signal indicating that to the control unit 7. The receiver sensor 5 is switched between on and off under the control of the control unit 7.

The reception unit sensor 5 may detect that the human body is close when detecting that the distance from the human body is 120 mm or less, for example. Alternatively, the receiver sensor 5 may detect that the human body is close when it detects that the distance from the human body is 150 mm or less.

The receiver unit sensor 5 is, for example, a non-contact sensor or a contact sensor. When the receiver sensor 5 is a non-contact sensor, the receiver sensor 5 may detect a change in capacitance, for example, or may detect infrared light reception. When the reception unit sensor 5 is a contact sensor, the method by which the reception unit sensor 5 detects contact may be, for example, a resistance film method that detects pressure or a capacitance method. The receiver sensor 5 may be an analog sensor or a digital sensor, for example.

When the reception unit sensor 5 is a non-contact sensor, when the user brings his ear close to the reception unit 2, the reception unit sensor 5 in the vicinity of the reception unit 2 detects that the user's ear has approached. In other words, the receiver sensor 5 detects that the user's ear has approached the receiver 2.

When the reception unit sensor 5 is a contact sensor, when the user touches the ear to the reception unit 2, the reception unit sensor 5 in the vicinity of the reception unit 2 detects that the user's ear is in contact. Accordingly, the receiver sensor 5 detects that the user's ear has approached the receiver 2.

The transmitter unit 6 is provided in the vicinity of the transmitter unit 3, and detects the state in which the human body (parts such as ears, fingers, and hands) is close to the transmitter unit 3, as with the receiver unit sensor 5. Here, the transmitter unit 6 is provided in the vicinity of the transmitter unit 3 so that it is possible to detect a state in which the user's finger or palm is close to the transmitter unit 3 during a call. For example, the transmitter unit 6 may be provided within a radius of 10 mm from the transmitter unit 3 in the vicinity of the transmitter unit 3.

When the transmission unit sensor 6 detects a state in which the human body is close to the transmission unit 3, the transmission unit sensor 6 outputs a signal indicating that to the control unit 7. The receiver sensor 5 is also switched on and off under the control of the controller 7. Similarly to the receiver unit sensor 5, the transmitter unit sensor 6 may be a non-contact sensor or a contact sensor. Further, it may be an analog sensor or a digital sensor.

For example, when detecting that the distance from the human body is 10 mm or less, or 5 mm or less, the transmitter unit sensor 6 may detect that the human body is close. Alternatively, the transmitter sensor 6 may be a contact sensor, and may detect that “the human body has approached” when the transmitter sensor 6 detects contact with the human body.

The control unit 7 controls the reception unit 2, the transmission unit 3, the communication unit 4, the reception unit sensor 5, and the transmission unit sensor 6. For example, when the user performs an operation to make a call on the mobile terminal 1, the control unit 7 controls the communication unit 4 to connect to the communication partner designated by the user. Further, the control unit 7 causes the user to output the voice of the other party from the receiver 2, and causes the user to output the voice of the user from the transmitter 3.

Further, the control unit 7 performs control so as to switch on / off the receiver unit sensor 5 and the transmitter unit sensor 6. The control unit 7 is an integrated circuit having, for example, a CPU (Central Processing Unit).

Although not shown in FIG. 1, the mobile terminal 1 includes an operation unit such as a button for a user to operate in a call, a power supply unit such as a battery that supplies power to each unit, a display unit such as a liquid crystal screen, and the like. May be provided.

FIG. 2 is an example of the mobile terminal 1 according to the present embodiment. Here, as the mobile terminal 1, a so-called smartphone having a large display screen is illustrated. The receiver 2 and receiver sensor 5 are provided in the upper part of the casing 100, and the transmitter 3 and transmitter sensor 6 are provided in the lower part of the casing 100. In the center of the housing 100, a display unit 8 composed of a touch panel or the like is provided. A control unit 7 is provided inside the housing 100.

FIG. 3 is another example of the mobile terminal 1 according to the present embodiment. In FIG. 3, a so-called straight-type mobile phone is illustrated as the mobile terminal 1. The receiver 2 and receiver sensor 5 are provided in the upper part of the casing 101, and the transmitter 3 and transmitter sensor 6 are provided in the lower part of the casing 101. In the center of the housing 101, a display unit 8 constituted by a liquid crystal display or the like and an operation unit 9 constituted by buttons are provided. A control unit 7 is provided inside the housing 101.

Next, the operation of this embodiment will be described. FIG. 4 is a flowchart illustrating an example of control processing of the control unit 7 in accordance with the detection results of the receiving unit sensor 5 and the transmitting unit sensor 6.

The control unit 7 determines whether or not the user is in a call using the mobile terminal 1 according to the signal output from the communication unit 4 (step S1).

If the user is not busy (No in step S1), the control unit 7 turns off the receiver sensor 5 and the transmitter sensor 6 (step S2).

If the user is busy (Yes in step S1), the control unit 7 turns on the receiver sensor 5 and the transmitter sensor 6 (step S3). Then, the proximity of the human body to the reception unit 2 and the transmission unit 3 is detected by the reception unit sensor 5 and the transmission unit sensor 6 as described above.

Subsequently, the control unit 7 acquires the detection result of the receiver unit sensor 5 (step S4). Based on the signal from the receiver sensor 5, the controller 7 determines whether or not the receiver sensor 5 has detected the proximity of a human body.

Next, the control unit 7 acquires the detection result of the transmitter unit sensor 6 in the same manner as in step S4 (step S5). Based on the signal from the transmitter sensor 6, the controller 7 determines whether or not the transmitter sensor 6 has detected the proximity of a human body.

In accordance with the detection results obtained from the receiver sensor 5 and the transmitter sensor 6, the controller 7 determines whether the current receiver sensor 5 and transmitter sensor 6 are in any of four types of patterns (described later). (Step S6).

Here, there are four patterns, pattern 1 to pattern 4, as shown in FIG. 5, as the combination pattern of the detection result by the receiver sensor 5 and the detection result by the transmitter sensor 6.

FIG. 5 is a chart showing an example of control processing performed by the control unit 7 in step S7 based on the pattern determined by the control unit 7 in step S6 of FIG. Hereinafter, details of the control performed by the control unit 7 in step S7 will be described with reference to FIG.

“Pattern 1” in FIG. 5 corresponds to the control unit 7 when the receiver sensor 5 detects “proximity” of the human body in step S4 of FIG. 4 and the transmitter sensor 6 detects “non-proximity” of the human body in step S5. Is the pattern determined in step S6.

“Pattern 2” is determined by the control unit 7 in step S6 when the receiver sensor 5 detects “proximity” of the human body in step S4 and the transmitter sensor 6 detects “proximity” of the human body in step S5. It is a pattern.

“Pattern 3” is determined by the controller 7 in step S6 when the receiver sensor 5 detects “non-proximity” of the human body in step S4 and the transmitter sensor 6 detects “proximity” of the human body in step S5. Pattern.

“Pattern 4” is obtained when the receiving unit sensor 5 detects “non-proximity” of the human body in step S4 and the transmission unit sensor 6 detects “non-proximity” of the human body in step S5. It is a pattern to determine.

The control unit 7 controls the voice output from the transmitting unit 3 to the other party according to the pattern determined in step S6 (step S7).

In the case of the pattern 1, the receiver sensor 5 detects the proximity of the human body and the receiver 2, and the transmitter sensor 6 does not detect the proximity of the human body and the transmitter 3. From this detection result, it is assumed that the user is in a call without bringing the ear close to the receiver 2 and the palm or the like close to the transmitter 3. In this state, it is desirable that the control unit 7 performs control so that the user can talk as it is.

From the detection result of pattern 1, the control unit 7 performs control to continue the call state. In other words, the control unit 7 outputs the voice from the other party for the receiver unit 2 and outputs the voice from the user to the other party for the transmitter unit 3 so that the user can make a normal call. Control as you can.

In the case of pattern 2, the receiver sensor 5 detects the proximity of the human body and the receiver 2, and the transmitter sensor 6 also detects the proximity of the human body and the transmitter 3. From this detection result, it is assumed that the user closes the transmitter 3 with a palm or the like while keeping his ear close to the receiver 2 (the palm or the like is close to the transmitter 3). That is, it is assumed that the user is interrupting the call. In this state, it is desirable to prevent the voice from the microphone from being heard by the other party. Further, since the user's ear is close to the receiver 2, it is assumed that the user is willing to hear the voice from the other party. That is, it is not desirable that the voice from the receiver 2 is not output to the user.

Here, “to prevent the voice from the microphone from being heard by the other party” means that the voice that the user speaks to the transmitter 3 does not reach the other party at all, or can be heard very small. It means to suppress the output of voice to the other party. Specifically, the control unit 7 lowers the gain of the amplifier provided in the transmission unit 3 or does not cause the communication unit 4 to output the user's voice signal output from the transmission unit 3 to the control unit 7, Control is performed. Moreover, the control part 7 may control so that a holding sound may be played with respect to the other party.

The control unit 7 controls only the transmitting unit 3 to the mute state according to the pattern determination (pattern 2). That is, the transmitter 3 is prevented from outputting voice to the other party, but the receiver 2 is made to output voice from the other party. For example, the receiving unit 2 outputs the voice from the other party at a volume substantially the same as that during a normal call. From this control, by performing a natural operation such as closing the transmitter 3 with a palm or the like without the user performing a holding operation, the mobile terminal 1 has an effect of preventing sound leakage to the other party. Furthermore, if the user wants to hear the voice of the other party, the natural operation of bringing the receiver 2 close to his / her ear also allows the user to keep listening to the voice from the other party.

In the case of Pattern 3, the receiver sensor 5 does not detect the proximity of the human body and the receiver 2. Further, the transmitter unit 6 detects the proximity of the human body and the transmitter unit 3. From this detection result, it is assumed that the user has released his / her ear from the receiver 2 and closed the call by closing the transmitter 3 with a palm or the like. That is, it is assumed that the user is interrupting the call. In this state, it is desirable that the control unit 7 prevents the voice from the microphone from being heard by the other party. Further, since the user's ear is away from the receiver 2, it is presumed that the user does not intend to hear the voice from the other party. That is, it is not always necessary to output the other party's voice from the receiver 2.

The control unit 7 controls the receiving unit 2 and the transmitting unit 3 to be in a mute state according to the pattern determination (pattern 3). That is, the output of the voice from the transmitter 3 to the other party is suppressed, and the voice from the other party is not output from the receiver 2. From this control, by performing a natural operation such as closing the transmitter 3 with a palm or the like without the user performing a holding operation, the mobile terminal 1 has an effect of preventing sound leakage to the other party. Furthermore, since the user removes the earpiece 2 from the ear, the voice from the earpiece 2 is also lost, which is more convenient when the user disconnects the phone and talks with the neighbor.

In the case of the pattern 4, the receiver sensor 5 does not detect the proximity of the human body and the receiver 2. The transmitter unit 6 also does not detect the proximity of the human body and the transmitter unit 3. In this case, it is assumed that the user does not bring his ear close to the receiver 2 and does not block the transmitter 3. In other words, the user is considered to have temporarily placed the telephone. In this case, the user may want to resume the call immediately after performing some work with both hands in a short time. Or, forgetting to put on hold, the mobile terminal 1 may be placed, and the user may not be willing to go to work somewhere else and immediately resume the call. Therefore, in the case of this pattern, it is desirable that the control unit 7 performs an operation of continuing the call state for a predetermined time, and performs control so as to suppress the output of voice to the other party after the predetermined time has elapsed.

When the control unit 7 determines that the pattern 4 is present, the control unit 7 determines whether or not this state has continued for a predetermined time. Note that the “predetermined time” is a time during which a call is interrupted due to a task that the user can complete immediately, for example, a time of about 10 seconds to several tens of seconds.

When the state of the pattern 4 has not continued for a predetermined time, the control unit 7 performs control to continue the call.

When the state of the pattern 4 continues for a predetermined time, the control unit 7 controls the transmission unit 3 to be in the mute state. This prevents the other party from hearing excessive voice. At this time, the control unit 7 may control both the reception unit 2 and the transmission unit 3 to the mute state. From this control, when the user performs a short-time operation with both hands in the mobile terminal 1, there is an effect that the user does not feel discomfort such as frustration by continuing the call for a predetermined time. Furthermore, when the user forgets to put the mobile terminal 1 on hold and the portable terminal 1 is left unattended, the transmitter 3 is automatically muted so as not to continue to emit sound to the other party. Can do.

The control unit 7 can perform voice control of the call more appropriately according to the operation of the user by performing the above control, and can prevent the other party from listening to unnecessary sounds. Once muted (

patterns

2, 3, and 4), the user holds the mobile terminal 1 in the normal call position so that the user receives the receiver 2 again and brings the transmitter 3 to the mouth. Since it becomes pattern 1 immediately, there is no extra operation and the user can return to a normal call.

As described above, the control unit 7 can appropriately control the call state by setting an appropriate distance threshold for detecting whether or not the reception unit sensor 5 is close as described above. When the user uses the mobile terminal 1, when the voice of the other party can be heard loudly by the user, it may be possible to talk by releasing the mobile terminal 1 from the ear by a predetermined distance. For example, when the threshold value for detecting whether or not the phone is close is relatively small (for example, 30 mm), the receiver unit sensor can be used by merely moving the mobile terminal 1 away from the ear even though the user does not intend to put the call on hold. No. 5 may not detect the proximity of the human body. As a result, the control unit 7 determines that the state that should originally be determined as the pattern 1 in the pattern determination of FIG. As a result, since the receiving unit 2 and the transmitting unit 3 are controlled to be in the mute state, the user cannot normally make a call.

From the above, it is desirable that the threshold value for detecting whether or not the receiver unit 5 is close is set to 120 mm, 150 mm, or the like. In other words, the threshold value for detecting whether or not the reception unit sensor 5 is close is set to a value that detects the proximity of the human body when the user is talking normally using the mobile terminal 1. Is desirable. As this threshold value, a larger threshold value such as 200 mm may be set. In order to prevent the receiver sensor 5 from detecting an obstacle instead of the ear, the threshold value may be set to a relatively small value of about 100 mm.

As for the transmitter unit sensor 6, as described above, the control unit 7 can appropriately control the call state by setting an appropriate distance threshold for detecting whether or not the transmitter unit is close. When the user uses the mobile terminal 1, it is conceivable that the mobile terminal 1 is brought close to the mouth so that the other party can easily hear the user's voice. In such a case, for example, when the threshold value for detecting whether or not the mobile phone is close is about 40 mm, the mobile terminal 1 is moved close to the mouth even though the user does not intend to put the call on hold. The speech sensor 6 may detect the proximity of the human body. As a result, the control unit 7 determines that the pattern 1 should be determined as the pattern 2 in the pattern determination of FIG. As a result, since the transmitter 3 is controlled to be in the mute state, the user cannot normally make a call.

From the above, it is desirable that the threshold for detecting whether or not the transmitter unit 6 is in proximity is set to 10 mm, 5 mm, or the like. In other words, the threshold value for detecting whether or not the transmitter sensor 6 is close is set to a value that does not detect the proximity of the human body when the user is talking normally using the mobile terminal 1. Is desirable. When the user covers the transmitter 3 with a palm or the like, the transmitter sensor 6 detects proximity.

Furthermore, the transmitter unit 6 may be a contact sensor when the transmitter unit 3 is muted only when the receiver unit 5 is blocked with the intention of the user holding it.

The control unit 7 controls only the transmitting unit 3 in the mute state in the pattern 2 in FIG. 5 and controls the receiving unit 2 and the transmitting unit 3 in the mute state in the pattern 3. However, the control unit 7 may control only the transmitting unit 3 in the mute state even in the pattern 3. The control unit 7 can also perform other controls in the pattern 2 and the pattern 3, such as suppressing the output of voice to the other party.

In FIG. 4, the control unit 7 acquires the detection result of the receiver sensor 5 first and the detection result of the transmitter sensor 6 later, but this acquisition process may be performed in the reverse order or is performed simultaneously. May be.

Further, when the control unit 7 performs the control shown in FIG. 5, the control unit 7 may perform control to display that effect on the screen of the mobile terminal 1. For example, in the pattern 3 shown in FIG. 5, when the control unit 7 sets the receiving unit 2 and the transmitting unit 3 to the mute state, if the mute state of the transmitting unit 3 continues for 30 seconds, the control unit 7 Control is performed so that “Speaker and microphone are muted: 30 seconds” is displayed on the screen. By this display, the user can confirm the time set in the mute state. The control unit 7 can perform the same control with the other patterns shown in FIG.

Embodiment 2
The mobile terminal according to the present embodiment includes a display unit, and a part of the display unit serves as a receiver sensor according to the first embodiment during a call. Thereby, the sensor provided in the housing | casing of a portable terminal can be reduced from two pieces to one piece. Further, as in the first embodiment, the mobile terminal can more appropriately control the call state so that the call partner does not hear an unnecessary sound. Embodiments of the present invention will be described below with reference to the drawings. Note that the description similar to that in Embodiment 1 is omitted as appropriate.

FIG. 6 is a block diagram showing an example of the overall configuration of the mobile terminal according to the present embodiment.

6, the display unit 81 is a touch display or the like, and displays information such as a telephone address and time according to the control of the control unit 7. Further, for example, as shown in FIG. 7, a part of the display unit 81 is a contact sensor unit 50. The contact sensor unit 50 is a part of the display unit 81 located in the vicinity of the receiver unit 2. Here, the display unit 81 is provided in the vicinity of the receiver unit 2 so as to detect a state in which a human body is close to the receiver unit 2. For example, the display unit 81 may be provided within a radius of 10 mm from the receiver unit 2 in the vicinity of the receiver unit 2.

The contact sensor unit 50 functions in the same manner as the receiver unit sensor 5 described in the first embodiment when the user is talking. The contact sensor unit 50 is configured by a resistive film type, capacitive type touch display, or the like, and can detect contact of a human body (ear, finger, hand, etc.). The contact sensor unit 50 operates as a display unit when the user is not in a call.

Thereby, the mobile terminal can appropriately control the audio and video of the videophone so that the other party does not provide unnecessary sound and video. Hereinafter, the present embodiment will be described with reference to the drawings. Note that descriptions similar to those in

Embodiments

1 and 2 are omitted as appropriate.

FIG. 8 is a block diagram showing an example of the overall configuration of the mobile terminal according to the present embodiment. A mobile terminal 1 according to the present embodiment includes a receiver unit 2, a transmitter unit 3, a communication unit 4, a control unit 7, a display unit 8, a camera unit 10, and a proximity sensor 11. The mobile terminal 1 is a mobile terminal capable of making a videophone call using a mobile phone, a smartphone, or the like.

The communication unit 4 can make a normal telephone call and a videophone call. The communication unit 4 outputs the video information input from the control unit 7 to the base station as radio, similar to the audio information. The communication unit 4 outputs the audio information and video information output from the base station to the control unit 7 as electric signals. When the user is making a videophone call, the communication unit 4 outputs a signal indicating that the videophone call is being made to the control unit 7.

The display unit 8 is a liquid crystal display, a touch display, or the like, and displays information according to the control of the control unit 7. In a videophone, the display unit 8 acquires video information of the other party from the control unit 7 and displays it as a video.

The camera unit 10 is for the user of the mobile terminal 1 to take a picture of himself / herself and send it to a videophone call partner. The video input from the camera unit 10 is output to the control unit 7 as video information of an electrical signal.

The proximity sensor 11 is a non-contact sensor provided in the vicinity of the transmitter 3. The proximity sensor 11 is switched on and off under the control of the control unit 7. The specific type of the proximity sensor 11 is as described in the first embodiment. The proximity sensor 11 is provided at a location different from the camera unit 10.

FIG. 9 is an example of the mobile terminal 1 according to the present embodiment. The receiver unit 2 and the camera unit 10 are provided in the upper part of the housing 103, the display unit 8 is provided in the center of the housing 103, and the transmitter unit 3 and the proximity sensor 11 are provided in the lower part of the housing 103.

The control of the control unit 7 will be described. First, as described in step S1 of FIG. 4, the control unit 7 determines whether or not the user is currently in a videophone call based on the signal from the communication unit 4.

When the user is not in a call, the control unit 7 turns off the proximity sensor 11.

When the user is talking on the videophone, the control unit 7 turns on the proximity sensor 11. Thereafter, the control unit 7 controls the call according to the detection result of the proximity sensor 11.

For example, when the user brings a finger or the like close to the proximity sensor 11, the control unit 7 suppresses output of sound from the transmitter 3 to the other party and output of video from the camera unit 10 to the other party.

As a specific example of “suppressing output of video to the other party”, the control unit 7 does not output the video information from the camera unit 10 to the communication unit 4, but transmits information indicating that the video is on hold to the communication unit 4. Output to. The communication unit 4 transmits the information to the call partner. As a result, the information indicating the hold is output on the screen of the mobile terminal or the like of the other party, and the video information from the camera unit 10 is not output. Here, the screen information seen by the call partner may be transmitted directly from the user's mobile terminal 1 to the call partner's mobile terminal or the like. You may make it display on the portable terminal etc. of the side.

As another specific example of “suppressing output of video to a call partner”, there is a method of displaying video information from the camera unit 10 with a very small output to the call partner. Note that “suppressing the output of sound” is as described in the first embodiment.

When the user releases a finger or the like that is close to the proximity sensor 11, the control unit 7 releases the above-described state. That is, the control unit 7 resumes the videophone call. As described above, the control unit 7 can control the videophone.

Note that the present invention is not limited to the above-described embodiment, and can be appropriately changed without departing from the spirit of the present invention. In other words, various changes that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention. For example, the reception unit sensor 5 and the transmission unit sensor 6 in the first and second embodiments may be a combination of a plurality of types of sensors. In the first to third embodiments, each sensor is off when not in a call or the like, but may be on in that case.

In Embodiment 3, the position of the proximity sensor 11 may be another place of the mobile terminal 1. For example, the proximity sensor 11 may be provided in the vicinity of the camera unit 10. Note that the mobile terminal 1 may include a contact sensor instead of the proximity sensor 11 that is a non-contact sensor. In that case, the control unit 7 performs the same control as in the third embodiment when the user touches the contact sensor with a finger or the like.

In Embodiment 3, the camera unit 10 is provided in the mobile terminal 1, but may be a camera provided externally to the mobile terminal 1. Further, the camera unit 10 itself provided in the mobile terminal 1 may have the proximity sensor 11. In that case, when the user brings a finger or the like close to the camera unit 10, the proximity sensor 11 provided in the camera unit 10 detects the proximity as described above. The control unit 7 performs the same control as described above according to the detection. Alternatively, the camera unit 10 provided externally may have a proximity sensor 11.

In addition, when a sensor is provided in the camera unit 10, if a user's finger or the like directly contacts the camera unit 10, the camera lens may be contaminated. For this reason, the sensor provided in the camera unit 10 is preferably a proximity sensor rather than a contact sensor.

In the third embodiment, even after the finger or the like is removed from the proximity sensor 11, the control unit 7 performs control to suppress output of audio from the transmitter 3 to the other party and output of video from the camera unit 10 to the other party. You may continue. In this case, when the user operates a key such as a call key, the control unit 7 releases the control. When the display unit 8 is a touch panel, the control unit 7 may cancel the control by touching the display unit 8.

Furthermore, the mobile terminal 1 of Embodiment 3 may be provided with a plurality of proximity sensors or contact sensors. In that case, when the user brings a finger or the like close to one of the plurality of sensors, the control unit 7 controls the output of audio and the output of video as described above.

In the above-described embodiment, the present invention has been described as a hardware configuration, but the present invention is not limited to this. The present invention can also realize an arbitrary processing method by causing a CPU (Central Processing Unit) to execute a computer program. Further, the above-described program can be stored using various types of non-transitory computer-readable media and supplied to a computer.
