As shown in FIG. 1, a mobile phone terminal device according to this embodiment includes a control unit 1 that controls the entire device, an audio signal processing unit 3 and a video signal that are controlled by the control unit 1, respectively. A processing unit 4 is provided. In addition, a transmission / reception unit 2, a storage unit 5, an operation unit 6, and a display unit 7 connected to the control unit 1 are provided. An antenna 8 is connected to the transmission / reception unit 2, a speaker 9 and a microphone (hereinafter referred to as a microphone) 10 are connected to the audio signal processing unit 3, and an imaging unit 11 is connected to the video signal processing unit 4.

制御部１はマイクロコンピュータで構成されており、ＣＰＵ、ＲＯＭ及びＲＡＭを備えている。音声信号処理部３はマイク１０から入力された音声信号をデジタル化及び圧縮符号化して送受信部２へ送り、送受信部２から送られてくるデジタル化及び圧縮符号化された音声データを圧縮復号化及びアナログ化してスピーカ９へ出力する。映像信号処理部４は撮像素子１１で生成された被写体の映像信号をデジタル化及び圧縮符号化して映像データとし、送受信部２へ送る。送受信部２は音声信号処理部３から送られてくる音声データ及び映像信号処理部４から送られてくる映像データを変調及び増幅してアンテナ８へ送出し、アンテナ８で受信した音声データを復調して音声信号処理部３へ送る。また、送受信部２は発信及び着信動作を行う。記憶部５はフラッシュメモリ等のような書換可能な不揮発性メモリであり、ユーザが設定した電話帳データ、緊急連絡先の電話番号、着信音及びメロディー、キー操作音等が記憶される。操作部６はユーザがこの携帯電話端末装置を使用するときに用いる数字キー６１、オフフックキー６２、切断キー６３、緊急事態モード設定キー６４等を備えている。表示部７は液晶表示装置からなり、ユーザが操作部６から入力した電話番号やこの携帯電話端末装置の動作状態等を表示する。   The control unit 1 is configured by a microcomputer and includes a CPU, a ROM, and a RAM. The audio signal processing unit 3 digitizes and compresses and encodes the audio signal input from the microphone 10 and sends it to the transmission / reception unit 2, and compresses and decodes the digitized and compression-encoded audio data sent from the transmission / reception unit 2. And it is converted into an analog signal and output to the speaker 9. The video signal processing unit 4 digitizes and compresses and encodes the video signal of the subject generated by the image pickup device 11 into video data, and sends the video data to the transmission / reception unit 2. The transmission / reception unit 2 modulates and amplifies the audio data sent from the audio signal processing unit 3 and the video data sent from the video signal processing unit 4, sends them to the antenna 8, and demodulates the audio data received by the antenna 8. To the audio signal processing unit 3. The transmission / reception unit 2 performs outgoing and incoming calls. The storage unit 5 is a rewritable nonvolatile memory such as a flash memory, and stores telephone directory data set by the user, telephone numbers of emergency contacts, ringtones and melodies, key operation sounds, and the like. The operation unit 6 includes a numeric key 61, an off-hook key 62, a disconnect key 63, an emergency mode setting key 64, and the like used when the user uses the mobile phone terminal. The display unit 7 is composed of a liquid crystal display device, and displays the telephone number input by the user from the operation unit 6 and the operating state of the mobile phone terminal device.

以上の構成を有する携帯電話端末装置の通常の通話時の動作及び緊急事態モードに設定されたときの動作を説明する。   The operation at the time of a normal call and the operation when the mobile phone terminal device having the above configuration is set to the emergency mode will be described.

通常の通話を行うときは、ユーザは操作部６のオフフックキー６２を押した後、数字キー６１から通話を行おうとする相手の電話番号を入力する。制御部１は、数字キー６１から入力された電話番号に発信するための発信制御情報を生成して送受信部２へ送り、送受信部２はこの発信制御情報をアンテナ８から送信する。最寄りの携帯電話基地局はアンテナ８から送信された発信制御情報を受信し、携帯電話網及び固定電話網を経由して発信先の携帯電話端末装置又は固定電話端末装置に接続する。   When performing a normal call, the user presses the off-hook key 62 of the operation unit 6, and then inputs the telephone number of the other party to call from the numeric keys 61. The control unit 1 generates transmission control information for transmitting to the telephone number input from the numeric key 61 and sends it to the transmission / reception unit 2, and the transmission / reception unit 2 transmits this transmission control information from the antenna 8. The nearest mobile phone base station receives the transmission control information transmitted from the antenna 8 and connects to the mobile phone terminal device or the fixed phone terminal device of the destination via the mobile phone network and the fixed telephone network.

ここで、各キーを操作したとき、制御部１の制御に基づいてキー操作音がスピーカ１０から出力される。また、オフフックキー６２を押したときはダイヤルトーンがスピーカ１０から出力され、発信先を呼び出しているときはリングバックトーンがスピーカ１０から出力される。さらに、発信先を呼び出しているときは表示部７に発信先の電話番号が表示される。   Here, when each key is operated, a key operation sound is output from the speaker 10 based on the control of the control unit 1. When the off-hook key 62 is pressed, a dial tone is output from the speaker 10, and when a call destination is called, a ring back tone is output from the speaker 10. Further, when calling the destination, the telephone number of the destination is displayed on the display unit 7.

発信先が呼出に応答してオフフックすると、発信先と接続され、通話状態となる。通話状態では、ユーザの発した音声がマイク１０で音声信号に変換され、音声信号処理部３でデータ圧縮処理等を受け、送受信部２で変調されて、アンテナ８から送信される。アンテナ８から送信された音声信号は携帯電話網及び固定電話網を経由して、発信先の携帯電話端末装置又は固定電話端末装置に伝送され、そのスピーカや受話器で音声が出力（再生）される。発信先の相手が発した音声も同様にしてスピーカ９から出力される。この通話中は、表示部７に、通話中であること、通話継続時間等が表示される。   When the call destination responds to the call and goes off-hook, the call is connected to the call destination and enters a call state. In the call state, the voice uttered by the user is converted into a voice signal by the microphone 10, subjected to data compression processing or the like by the voice signal processing unit 3, modulated by the transmission / reception unit 2, and transmitted from the antenna 8. The audio signal transmitted from the antenna 8 is transmitted to the mobile phone terminal device or the fixed phone terminal device of the destination via the mobile phone network and the fixed phone network, and the sound is output (reproduced) by the speaker or the receiver. . Similarly, the voice uttered by the other party is output from the speaker 9. During the call, the display unit 7 displays that the call is in progress, the call duration, and the like.

次に、ユーザが緊急事態モード設定キー６４を押したときの動作については、図２のフローチャートを参照しながら説明する。なお、このフローチャートの処理は、一旦終了した後も、携帯電話端末装置の電池が消耗するか又は取り出されるかして電源が供給されなくなる迄制御部１により繰り返し実行される。   Next, the operation when the user presses the emergency mode setting key 64 will be described with reference to the flowchart of FIG. Note that the processing of this flowchart is repeatedly executed by the control unit 1 even after it has been temporarily ended until the battery of the mobile phone terminal device is exhausted or removed and no power is supplied.

制御部１は、緊急事態モード設定キー６４が押されたことを検出すると（ステップＳ１でYES ）、予め記憶部５に設定されている緊急連絡先（警察署、警備会社、自宅等）の電話番号を読み出し、その電話番号に発信するための発信制御情報を生成して送受信部２へ送ると共に、発信状態の表示を行わないように制御する（ステップＳ２）。ここで、緊急事態モード設定キー６４については、他のキーとは異なり、キー操作音がスピーカ１０から出力されないように構成されている。   When the control unit 1 detects that the emergency mode setting key 64 has been pressed (YES in step S1), the telephone of the emergency contact information (police station, security company, home, etc.) previously set in the storage unit 5 The number is read, transmission control information for making a call to the telephone number is generated and sent to the transmission / reception unit 2, and control is performed so as not to display the transmission state (step S2). Here, unlike the other keys, the emergency mode setting key 64 is configured such that no key operation sound is output from the speaker 10.

送受信部２はこの発信制御情報をアンテナ８から送信し、最寄りの携帯電話基地局はアンテナ８から送信された発信制御情報を受信し、携帯電話網及び固定電話網を経由して緊急連絡先に接続する。このとき、制御部１は、ダイヤルトーン及びリングバックトーンがスピーカ１０から出力されないように、かつ、発信先の電話番号等が表示部７に表示されないように制御している。即ち、待機状態又は表示などが消えた電源オフの状態になる。   The transmission / reception unit 2 transmits this transmission control information from the antenna 8, and the nearest mobile phone base station receives the transmission control information transmitted from the antenna 8, and sends it to the emergency contact via the mobile phone network and the fixed telephone network. Connecting. At this time, the control unit 1 performs control so that dial tone and ringback tone are not output from the speaker 10, and the telephone number of the destination is not displayed on the display unit 7. That is, a standby state or a power-off state in which a display or the like disappears.

緊急連絡先が呼出に応答してオフフックすると（ステップＳ３でYES ）、通話状態となる。通話状態では、マイク１０から入力された音声を緊急連絡先へ送信する送話パスを接続すると共に撮像素子１１及び映像信号処理部４を自動的に動作させる。また、緊急連絡先からの音声がスピーカ１０から出力されないようにする。さらに、操作部６のキー操作を無効にすると共にキー操作音がスピーカ１０から出力されないようにする。また、表示部９のバックライトを消す（ステップＳ４）。つまり、マイク１０から入力された音声と撮像素子１１で撮影された映像を緊急連絡先へ送信することは可能であるが、見かけ上は電源スイッチをオフにした状態と同じである。この状態でマイク１０から入力された音声及び撮像素子１１で撮像された映像は、それぞれ音声信号処理部３及び映像信号処理部４で所定の処理を受け、送受信部２で変調及び増幅されて、アンテナ８から送信され、緊急連絡先へ送られる（ステップＳ５）。この送信動作は緊急連絡先が切断操作を行う迄継続される（ステップＳ６）。なお、緊急連絡先が切断操作を行った場合は処理が終わるが、一定時間後に再びステップＳ１から繰り返す。   When the emergency contact is off-hook in response to the call (YES in step S3), a call state is entered. In the call state, the transmission path for transmitting the voice input from the microphone 10 to the emergency contact is connected and the image sensor 11 and the video signal processing unit 4 are automatically operated. In addition, the sound from the emergency contact is not output from the speaker 10. Furthermore, the key operation of the operation unit 6 is disabled and the key operation sound is not output from the speaker 10. Further, the backlight of the display unit 9 is turned off (step S4). That is, it is possible to transmit the voice input from the microphone 10 and the video imaged by the image sensor 11 to the emergency contact, but it looks the same as when the power switch is turned off. In this state, the audio input from the microphone 10 and the video imaged by the imaging device 11 are subjected to predetermined processing by the audio signal processing unit 3 and the video signal processing unit 4, respectively, and modulated and amplified by the transmission / reception unit 2, It is transmitted from the antenna 8 and sent to the emergency contact address (step S5). This transmission operation is continued until the emergency contact performs a disconnection operation (step S6). Note that the process ends when the emergency contact performs a disconnection operation, but repeats from step S1 again after a certain time.

従って、例えば拉致・誘拐等の事件に遭遇した被害者が緊急事態モード設定キー６４を押した場合、緊急連絡先への発信動作が犯人に気付かれることはなく、また接続した後は犯人の話し声等の音声、及び付近の映像が犯人に気付かれずに緊急連絡先へ送信される。さらに、送信中は切断キー６３等の操作が無効になっているため、携帯電話端末装置から送信動作を停止することはできない。また、緊急連絡先が回線を切断したとしても、緊急連絡先に対する発信を繰り返すため、緊急先への音声及び映像の送信が途絶えることはない。   Therefore, for example, if a victim who encounters an incident such as abduction or kidnapping presses the emergency mode setting key 64, the criminals will not be aware of the call to the emergency contact, and the voice of the criminals after connecting Etc. and nearby images are transmitted to the emergency contact without being noticed by the criminal. Furthermore, since the operation of the disconnect key 63 or the like is disabled during transmission, the transmission operation cannot be stopped from the mobile phone terminal device. Further, even if the emergency contact is disconnected, the transmission to the emergency contact is repeated, so that transmission of audio and video to the emergency destination is not interrupted.

なお、以上の実施形態では、緊急事態モードに設定するための専用キーを設けたが、専用キーを設けずに、数字キー及び記号キー（＃、＊）を用いて所定の数字及び記号を入力したときに緊急事態モードに設定するように構成してもよい。また、キーを用いる代わりに、被害者が発した緊急事態を示す音声を認識したときに緊急事態モードに設定するように構成してもよい。さらに、記憶部５に複数の緊急連絡先をそれらの優先順位と共に登録しておき、優先順位の最も高い緊急連絡先に接続できなかった場合には、次の優先順位の緊急連絡先に発信するように構成してもよい。   In the above embodiment, the dedicated key for setting the emergency mode is provided, but a predetermined number and symbol are input using the numeric key and the symbol key (#, *) without providing the dedicated key. The emergency mode may be set when the emergency mode is set. Moreover, you may comprise so that it may set to an emergency mode, when the audio | voice which shows the emergency which the victim emitted is recognized instead of using a key. Further, a plurality of emergency contacts are registered in the storage unit 5 together with their priorities, and when the emergency contact with the highest priority cannot be connected, the emergency contact with the next priority is transmitted. You may comprise as follows.
