Recently, the rapid improvement of the multimedia information processing technology and the development of the high-speed communication system has caused a high interest in the multimedia information service.

In addition, with the rapid development of industrial and communication technology, micro cameras and microphones have been developed and used, and the situation caused by the abuse of such micro cameras and microphones is rapidly increasing. For example, a micro camera or microphone may be installed in a place such as a toilet, a dressing room, or a hotel, and the camera and microphone may be used to observe or listen to the internal situation of the places, and to record or record it for illegal use. By using it, the form which violates personal privacy is increasing rapidly.

Thus, conventionally, a detector or a wiretap was detected by carrying a detector separately.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram illustrating a structure of a sneak camera and a hearing aid detecting apparatus using a voice recording apparatus according to an embodiment of the present invention, and FIG. 3 is a sneak camera using a voice recording apparatus according to an embodiment of the present invention; It is a flowchart which shows the operation procedure of a wiretap detector.

As shown in FIG. 2, the sneak camera and the wiretap detector using the small voice recording apparatus according to the present invention include a flash memory 50, a voice signal processor 100, a sneak camera and a wiretap detector 200, The key input unit 300 is configured to include a control unit (ALU) 400 and a display unit 500.

The flash memory 50 stores the voice signal converted into a digital signal and coded. The external voice signal, which is an analog signal by the encoder 110, is converted into a digital signal by receiving an external voice signal through a microphone. The coded voice signal is stored by the controller 400 according to the recording key input signal of the key input unit 300.

The voice processing signal unit 100 codes the voice signal received from the outside or decodes the voice signal recorded in the flash memory 50 in a form that can be heard by the user. The D converter 112 converts an external audio signal, which is an analog signal, into a digital signal, and then encodes the encoder 110 and codes the audio signal recorded in the flash memory 50. It is configured to include a decoding unit 120 for decoding by the decoder 122 and the D / A converter 124 in a form that can be heard.

The sneak camera and the wiretap detector 200 detect a strong field signal generated by the sneak camera or the wiretap, and a signal receiver 210 for receiving and detecting the strong field signal generated by the sneak camera or the wiretap, and the signal. And a signal amplifier 220 for amplifying the strong electric field signal output from the receiver 210.

The key input unit 300 applies a key input signal for recording and reproducing a voice signal and selecting a hidden camera and a wiretap detection.

The control unit (ALU) 400 compresses a signal input through the voice signal processing unit 100 according to the key input signal of the key input unit 300 with a compression contact G.729 and stores it in the flash memory 50. In addition, the data recorded in the flash memory 50 is decoded and reproduced through the voice signal processing unit 100, and the electric field strength according to the output signal of the sneak camera and the wiretap detector 200 is determined.

The display unit 500 outputs a signal output by the controller 400 to the outside, and outputs a speaker and earphone and an external voice that outputs a warning sound generated when an externally input voice signal and a strong electric field signal are detected. It is composed of LCD and blinking lamp to inform the status of signal and strong electric field signal.

Referring to Figures 2 and 3, a hidden camera and a wiretap detector using a voice recording device will be described in detail as follows.

First, when the mode of the voice signal processing unit 100 is selected by the key input unit 300 in order to use the voice signal processing function (S101), an external audio signal, which is an analog signal, is input through the microphone (S102). The external voice signal is converted into a digital signal by the A / D converter 112 and then coded by the encoder 114 (S103).

When the recording key input signal is applied to the controller 400 by the key input unit 300 (S104), the coded voice signal is recorded into the flash memory 50 after being converted into the digital signal (S105).

In this case, when the recording key input signal is not applied to the controller 400 by the key input unit 300, the playback key input signal is applied to the controller 400 by the key input unit 300 (S106). The audio signal recorded in the flash memory 50 is read, decoded by the decoder 122, and then converted into an analog audio signal by the D / A converter 124 (S107), and the converted audio signal is converted into a signal output unit. It outputs to the speaker or the earphone (500) (S108).

In other words, if the voice signal processing function signal is not selected by the key input unit 300 (S101), when the hidden camera and the eavesdropper detection function are selected (S201), it is applied to the control unit 400, and the control unit 400 The signal receiver 210, which is the sneak camera and the wiretap detector 200, is driven to receive and detect the strong field signal generated by the sneak camera or the wiretap.

Then, the detected strong electric field signal is amplified by the signal amplifier 220, and then controlled by a control unit according to the electric field strength of the amplified strong electric field signal, and output to the display unit 500 such as a speaker, earphone or LCD, and a flashing light. Inform the user.

At this time, when the electric field strength of the strong electric field signal is strong, the sound heard by the speaker and earphone is heard quickly and loudly, and the amplitude of the strong electric field signal appears large on the LCD, and the flashing light is quickly turned on / off.

On the contrary, when the electric field strength of the strong electric field signal is weak, the sound of the speaker and the earphone is heard slowly and small, and the amplitude of the strong electric field signal appears small on the LCD, and the flashing light is slowly turned on / off.

As described above, the sneak camera and the wiretap detector using the small voice recording device according to the present invention receive and detect the strong field signals generated from the sneak camera or the wiretap so as to perform the function of the detector in the small voice recording device. It is a device that can detect hidden cameras or taps by using a small voice recording device that is carried without a detector as a reminder to the user, thereby reducing anxiety about privacy exposure and reducing the inconvenience of having to carry a detector separately. It works.
