  The present invention relates to an information processing device, a portable terminal device, and an information processing method.

  As background art in this technical field, there is JP-A-2006-157786 (Patent Document 1). This gazette states that “when the determination result by the incoming call state determination circuit is an incoming call, the microcomputer controls the video processing unit to display information related to the presence of the incoming call on the OSD, and the determination result by the incoming call state determination circuit is the start of the call. In this case, the audio output is controlled by either reducing the volume to a predetermined level value for the audio processing unit or by muting the sound processing unit. The sound output is controlled so that the sound volume is restored to the original level value ”(see summary).

JP 2006-157786 A

  In the technique described in Patent Document 1, all radio waves from the mobile terminal within the reception range of the telephone signal receiving antenna are detected. Therefore, even when a person who is not a viewer of the video / audio output device (for example, a person in the adjacent room) makes a call on the mobile terminal, the volume of the video / audio output device is lowered, causing trouble to the viewer. May end up.

  In order to solve the above problems, for example, the configuration described in the claims is adopted.

  The present application includes a plurality of means for solving the above-described problems. For example, a mobile detection unit that detects the state of the mobile terminal and a sensor that detects that the user is talking on the mobile terminal. And an audio output unit that outputs an audio signal, and when the mobile detection unit detects an incoming call or a call of the mobile terminal, the audio output unit Output control is performed.

  According to the present invention, a suitable information processing technique can be provided.

It is an example of the block diagram of information processing apparatus. It is an example of the external view of information processing apparatus. It is a figure which shows the processing method in information processing apparatus. It is a schematic diagram of the output waveform of a sensor part. It is explanatory drawing of the output of a sensor part.

  Hereinafter, examples will be described with reference to the drawings.

  FIG. 1 is an example of a configuration diagram of the information processing apparatus 100 according to the first embodiment.

  The information processing apparatus 100 is a video / audio output apparatus such as a television apparatus, for example, and includes a sensor unit 101, a tuner 102, a video processing unit 103, an audio processing unit 104, a CPU 105, a memory 106, an OSD creation unit 107, and a video display unit 108. A voice output unit 109 and a portable detection unit 110. The mobile terminal 200 is a communication device such as a mobile phone.

  The sensor unit 101 detects movement of a person (viewer) within a predetermined range. Details will be described later. Data output from the sensor unit 101 is input to the CPU 105.

  The tuner 102 receives a broadcast signal such as digital broadcast, selects a channel, and demodulates it. The video signal demodulated by the tuner 102 is input to the video processing unit 103.

The video processing unit 103 performs predetermined video processing on the input video signal and outputs it to the video display unit 108. The video display unit 108 is a display such as a liquid crystal panel, for example, and displays the video signal processed by the video processing unit 103. At this time, various messages created by the OSD creation unit 107 can be combined and displayed on the video display unit 108.
The audio signal demodulated by the tuner 102 is input to the audio processing unit 104. The sound processing unit 104 performs predetermined sound processing on the input sound signal and outputs the sound signal to the sound output unit 109. The audio output unit 109 is, for example, a speaker, and outputs an audio signal subjected to audio processing by the audio processing unit 104.

  Note that the video display unit 108 and the audio output unit 109 may be output terminals for outputting information to an external display or a speaker.

  The CPU 105 performs a tuning operation of the tuner 102 and controls the video processing unit 103, the audio processing unit 104, the OSD creation unit 107, and the like.

  The memory 106 stores a control program used by the CPU 105 and data output from the sensor unit 101.

  The mobile detection unit 110 detects the state (incoming call, telephone call, etc.) of the mobile terminal 200, and information obtained here is sent to the CPU 105. When the mobile terminal 200 receives an incoming call, a base station (not shown) transmits an incoming signal to the mobile terminal 200. The portable terminal 200 recognizes the incoming call by receiving this incoming signal, and transmits a reception confirmation signal to the base station. Further, when the mobile terminal 200 starts a call, communication of an audio signal (data signal) is performed between the mobile terminal 200 and the base station. Therefore, the mobile detection unit 110 receives the radio wave transmitted from the mobile terminal 200 to the base station, and the state (incoming call, telephone call, etc.) of the mobile terminal 200 can be detected according to the type of the radio wave (communication). .

  FIG. 2 is an external view of the information processing apparatus 100.

  The sensor unit 101 is arranged on the front part of the information processing apparatus 100 and detects the movement of a person on the front part of the information processing apparatus 100. The video display unit 108 displays a video 120 from the video processing unit 103 and an OSD message 121 created by the OSD creation unit 107. FIG. 2 shows an example in which the OSD message 121 is combined with a part of the video 120 and displayed.

  FIG. 3 is a diagram showing a processing method in the information processing apparatus 100 of the present invention.

This process starts when the information processing apparatus 100 is powered on. When the processing is started, first, the recorded data in the memory 106 is erased in S301.
Next, in S302, it is confirmed whether there is an incoming call of the portable terminal 200. As described above, when the mobile terminal 200 receives an incoming call, the mobile terminal 200 transmits a signal to communicate with the base station. The portable detection unit 110 can detect an incoming call by receiving the signal. If there is no incoming call to the mobile terminal 200, the process returns to S302 to confirm again whether there is an incoming call to the mobile terminal 200. Thus, when there is no incoming call to the portable terminal 200, this is repeated.

  If it is detected in S302 that the mobile terminal 200 has received an incoming call, the process proceeds to S303, and an OSD message 121 indicating that the mobile terminal 200 has received an incoming call (e.g. OSD is displayed on the video display unit 108. Thereby, the viewer of the information processing apparatus 100 can surely know that the mobile terminal 200 has received an incoming call. Further, instead of the OSD display, a method of controlling the voice processing unit 104 to transmit an incoming call with voice information output from the voice output unit 109 or a method of reducing the volume output from the voice output unit 109 is used. May be. Furthermore, these processes may be performed in combination. With these processes, incoming calls can be transmitted more reliably.

  Next, in S304, recording of output data from the sensor unit 101 to the memory 106 is started, and the process proceeds to S305. In S <b> 305, it is confirmed whether a call is started on the mobile terminal 200.

  If it is not detected in step S305 that the mobile terminal 200 is in a call state, the process advances to step S313 to check whether the incoming call from the mobile terminal 200 is continuing. If the incoming call is continuing, the process returns to S305. This is repeated until the call is started. If it is detected in S313 that the incoming call has ended, it means that the call has not been answered for some reason. In this case, the process proceeds to S314, and the OSD message 121 displayed in S303 is hidden. . Then, the process returns to the first step of erasing the output data from the sensor unit 101 that has started recording in S304.

In S305, when it is detected that the mobile terminal 200 is in a call state, the process proceeds to S306, and the OSD message 121 displayed in S303 is hidden.
Next, in S307, the recorded output data from the sensor unit 101 is analyzed to detect that a person within the detection range of the sensor unit 101 is talking. The detection method will be described later.

  If it is not detected that a person in the detection range of the sensor unit 101 is talking, the process returns from S308 to S301 in the first step of this process. This is a case where a person who is not related to viewing is making a call on the mobile terminal 200 in another place because a person who is in the detection range of the sensor unit 101 is not making a call although a telephone call is started. This is because the information processing apparatus 100 does not need to perform subsequent processing.

If it is detected that a person in the detection range of the sensor unit 101 is talking, the process proceeds from S308 to S309, and the current volume setting information of the information processing apparatus 100 is stored in the memory 106.
In step S310, the sound processing unit 104 is controlled to reduce the volume of the sound output from the sound output unit 109. Thereby, the voice of the information processing apparatus 100 does not interfere with the call on the portable terminal 200.

Next, in S <b> 311, it is confirmed whether a call on the mobile terminal 200 is continued. If the call is ongoing, the process returns to S311 and is repeated if the call is ongoing.
When the call is finished, the process proceeds to S312 and the volume of the sound output from the sound output unit 109 is returned to the original state. By reading the volume setting information stored in S309 from the memory 106 and setting it to the value, the volume can be returned to the original state. Then, returning to the first step S301, the recorded output data from the sensor unit 101 is deleted.

  In the above process, the mobile terminal 200 receives a signal communicating with the base station and detects an incoming call and a call state. However, the present invention is not limited to this. For example, direct communication with the mobile terminal 200 may be performed by Bluetooth (registered trademark), a wireless LAN, or the like, and the state of an incoming call or a call on the mobile terminal 200 may be detected. In this case, it is assumed that the mobile terminal 200 transmits a signal corresponding to a state such as an incoming call or a call.

  Next, a method for detecting that a person within the detection range of the sensor unit 101 is making a call will be described.

  As a first method, there is a method of using a heat source movement detection type sensor such as a pyroelectric infrared sensor for the sensor unit 101. This sensor outputs a signal corresponding to the movement of the person (heat source) in the detection range, and a large signal waveform is output when the person moves. When no person is present in the detection area, there is no movement of the heat source, so a signal waveform close to 0 is output.

  When a call is made in response to an incoming call from the mobile terminal 200, the movement of a person who makes the call and the output waveform of the sensor unit 101 at that time will be described.

  FIG. 4 is a schematic diagram of an output waveform of the sensor unit 101.

  First, when there is an incoming call to the mobile terminal 200 (t1), an operation of moving to a place where the mobile terminal 200 is located (section a) is performed. Next, an operation (section b) is performed in which the mobile terminal 200 is picked up and a call button (not shown) of the mobile terminal 200 is pressed. Note that the time from t1 to pressing of the call button varies depending on the distance between the position of the mobile terminal 200 and the position of the person.

  The portable terminal 200 enters a call state from the time (t2) when the call button is pressed. After the call button is pressed, an operation (section c) in which the portable terminal 200 is put on the ear is performed. After that, a conversation (section d) is performed with the other party. Thus, before the time (t2) when the mobile terminal 200 is in a call state, there is an operation (section b) in which the mobile terminal 200 is picked up and the call button of the mobile terminal is pressed (section b). After t2), there is an operation (section c) in which the mobile terminal is put on the ear. Therefore, a threshold L is set, and if there is a sensor output exceeding the threshold L during a predetermined time (for example, about 2 seconds before and after) when the call is placed (t2), a call is being made. Is detected. On the other hand, when there is no sensor output exceeding the threshold value L (for example, when a person does not exist in the detection area or when a person does not perform the above operation), a call is not being made.

  If the movement of the person cannot be accurately detected for some reason, such as an obstacle between the sensor unit 101 and the person, the volume is unnecessarily determined by determining that the call is not being performed. Can be prevented from being lowered. Alternatively, if it is determined that a call is being made, even if a person is making a call, the voice of the information processing apparatus 100 does not interfere with the call.

  In the above description, the example in which the call is detected based on the operations before and after the point of time (t2) when the call is set is described. However, the present invention is not limited to this. t1) It may be detected that a call is being made based on the presence or absence of a movement operation of a person to a location where the mobile terminal 200 is located.

  As described above, by using a heat source movement detection type sensor such as a pyroelectric infrared sensor for the sensor unit 101, it is possible to determine whether or not there is a person who has made a call within the detection range of the sensor unit 101.

  As a second detection method, there is a method of using an imaging device (for example, a camera) that captures an image in the sensor unit 101. FIG. 5 is an explanatory diagram in which a part is cut out from the output video of the sensor unit 101 (imaging device). A person 501 is detected from the captured video, and the face area 502 of the person is analyzed and detected.

  If it is detected that the hand 503 is inside or near the face area 502 as in the example of FIG. 5A, it can be determined that the person is making a call using the mobile terminal 200. As in the example of FIG. 5B, when a hand cannot be detected in the vicinity of the face area 502, or when no person exists in the detection area of the sensor unit 101, it can be determined that the person is not making a call.

  If the person's face area 502 cannot be accurately detected for some reason, such as when there is an obstacle between the sensor unit 101 and the person, the volume is unnecessarily determined by determining that the call is not being performed. Can be prevented from being lowered. Alternatively, if it is determined that a call is being made, even if a person is making a call, the voice of the information processing apparatus 100 does not interfere with the call.

  As described above, since it is common that the portable terminal 200 is put on the ear after the call button is pressed, the mobile terminal 200 is detected within a predetermined time (several seconds) from when the call state of the portable terminal 200 is detected. If it is detected that the hand 503 is inside or in the vicinity of the face area 502, it can be determined whether or not a person is talking. Or, even if it is detected that the hand 503 is inside or in the vicinity of the face area 502 within a predetermined time (several seconds) from when it is detected that the mobile terminal 200 has received an incoming call, is the person talking? It can be judged whether or not.

  According to the present embodiment described above, it is determined whether or not the person who has made a call on the mobile terminal 200 is within the detection range of the sensor unit 101, and the person who is within the detection range of the sensor unit 101 makes a call on the mobile terminal 200. Since the volume of the information processing apparatus 100 is lowered when the operation is performed, the volume is not unnecessarily lowered. Further, when a person in the detection range of the sensor unit 101 makes a call, the volume of the information processing apparatus 100 is lowered, so that the sound of the information processing apparatus 100 does not interfere with the call. Furthermore, when the call ends, the volume automatically returns to the volume before the start of the call, so there is no need for the user.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, the above-described embodiments have been described in detail for easy understanding of the present invention, and are not necessarily limited to those having all the configurations described.

  Each of the above-described configurations, functions, processing units, processing means, and the like may be realized by hardware by designing a part or all of them with, for example, an integrated circuit. Each of the above-described configurations, functions, and the like may be realized by software by interpreting and executing a program that realizes each function by the processor.
