In general, mobile terminals were first developed by Bell Labs in the United States. Analog-based mobile telephones (AMPS) have led to the emergence of the mobile telephone market by efficiently using limited frequency resources. The telephone has expanded the mobile phone market in earnest by overcoming the limitations of analog systems. The evolution of the mobile phone service market is generally classified into first generation analog, second generation digital, and third generation IMT-2000.

Since the second generation of providing voice and short message (SMS) mobile communication services, mobile service providers are now moving to third generation technology capable of providing high-speed data services. Third-generation mobile communication technologies can provide new types of data services using higher bandwidths (1.9 GHz and above) than second generation (1.8 GHz and below), while consumers are not limited by time and place. Make the service available. Third generation mobile communication technology is expected to develop rapidly thanks to the combination of multimedia technology, voice recognition technology, mobile phone positioning technology, Bluetooth technology and the like. Europe's GSM method uses Wide Code Division Multiple Access (WCDMA) or Universal Mobile Telecommunication System (UMTS) technology through High Speed Circuit Switch Data (HSCSD), General Packet Radio Service (GPRS), and Enhanced Data rate for GSM Evolution (EDGE). Is in the process of transitioning.

TDMA in some parts of the United States and South America is selectively adopting EDGE or GPRS, and is expected to evolve to WCDMS or UMTS.

CDMA introduces cdma2000 1xRTT and 1xMC via cdmaOne IS-95A and IS-95B, and will evolve into cdma2000 3xRTT and cdma2000 3xMC via cdma 2000 1x EV-DO, HDR, 1x EV-DV and HRD. It is expected.

One of the features of IMT-2000 is that it can provide wireless multimedia services that can overcome high-speed data and video services by breaking the existing voice-oriented services. Accordingly, advanced functions such as a color display, a large memory, a digital camera, a wireless Internet platform, a multiplex sound, an MP3 function, and a VOD function are being adopted in the mobile communication terminal. In other words, the development of mobile communication service technology and the demands of consumers are accelerating the multimediaization of mobile communication terminals.

On the other hand, the camera module (Camera Module) mounted on the mobile communication terminal enables a video and photographing so that the subject can be seen on the screen through a micro lens. There are two types of camera modules: Charge-Coupled Device (CCD) and Complementary Metal-Oxide Semiconductor (CMOS). In recent years, the number of CCD-applied phones is increasing rapidly in CMOS due to image quality competition. In addition, a camera module with high sensitivity, high resolution Mega Pixel, and optical zoom is expected to be released.

When shooting with a camera mounted on a conventional mobile communication terminal to output a recording sound of more than 65 decibels, but those who secretly shoot a file that processes the shooting sound of the mobile communication terminal silently to the camera without shooting sound Take a picture.

Therefore, when the shooting sound MIDI file is updated to be silent, a problem occurs in which the other party is silently shooting.

The mobile station modem (MSM) 20 controls the overall operation of the mobile communication terminal, and the camera unit 25, which is composed of a musical instrument digital interface (MIDI) sound under the control of the MSM, reproduces the recording sound when the still image is taken. , The audio unit 22 for receiving and amplifying the recording sound of the MIDI unit 21 and the recording unit of the MIDI unit 21 and the speaker 23 for receiving the output of the audio amplifier 22 and producing sound, Measurement conversion unit 24 that detects the intensity of the output of the amplifier 22, converts it digitally, and provides data for judging the intensity, and the output value of the photographing sound is 65 decibels or more as an output value from the measurement conversion unit 24. It is composed of the MSM (20) for controlling the storage of the captured image by determining whether or not it was executed normally.

The present invention is to block the use of the processing of the mid-tone sound of the sound at the time of shooting in the camera unit 25 of the mobile communication terminal at the source. To pay.

The MIDI may be a decibel measuring device for measuring the output of the audio amplifier 22 and a converter for converting an analog signal into a digital signal to determine whether or not it corresponds to 65 decibels or more. The digital converter (ADC) is used to detect the strength of the output signal of the audio amplifier 22 and provide it to the MSM 20.

The MSM 20 cannot save a photograph when a certain voltage is lower than a certain voltage (e.g., 1.8V) when determining the strength of the MIDI sound as a voltage when the camera is currently photographed, or when the MIDI sound is changed, the MIDI is forcibly used. Control to change the shooting sound that you set as the sound, and make it sound constant after 65 decibels.

Therefore, when the picture is taken using the camera of the mobile communication terminal, the recording sound must be operated at an output of 65 decibels or more to control the stored picture.

The present invention implements a circuit for recognizing whether the MSM outputs a constant voltage (or decibels) in hardware when shooting by making a recording sound silent, and preventing a picture from being stored when the shooting sound is not output by software. Forcibly change the pre-set sound to make a certain sound to save the picture.
