The present invention relates to the output of the shooting sound generated when shooting a video signal with a camera of the multimedia portable terminal, in particular, by directly measuring the sound level of the output shooting sound to block the video signal shooting if the reference level or less, The present invention relates to a photographing sound output device and a method of a portable terminal forcibly amplifying a photographing sound to a reference level, outputting a corresponding announcement broadcast, and photographing a video signal when the forcibly amplified photographing sound output is permitted.

The mobile terminal (MS) moves freely in the service area formed by the corresponding base station (RAN: RADIO ACCESS NETWORK) of the registered mobile communication system and monitors and monitors the mobile switching station (MSC). It is a high-tech wireless communication device that allows an individual to always carry and move directly by wirelessly connecting and communicating with a desired party anytime and anywhere through a communication path established by control and switching.

The mobile terminal is relatively small in time used for communication, and is always carried and moved for the communication which may occur at any time, so the utilization of the portable terminal should be ensured.

Although the portable terminal is small in size and light in weight to secure mobility, there are some limitations in reducing the size and weight by adding various additional functions and additional services due to securing usability and development of related technologies. have.

As described above, the functions and services added to the portable terminal include, for example, a calculator function, a notepad function, a radio function, a game function, a camera function, a phone book function, a wireless internet service, an online game, a multimedia message service, and the like.

In addition, even in the communication method using the portable terminal, the first generation (1G) was a voice level (VOICE) communication method by an analog (ANALOG) signal, the second generation (2G) is a digital (DIGITAL) signal by a symbol character It is evolving into a text communication method using numbers, and in the current 3rd generation (3G), it is evolving into a multimedia communication method including voice, text, and video signals.

In order to perform multimedia communication with the mobile terminal MS, a camera CAMERA for capturing an image signal IMAGE SIGNAL must be provided integrally, and the camera is a still image when the mobile terminal MS is not used for communication. It is used as a digital camera for shooting (PHOTO) or as a video camera for shooting a movie.

When the multimedia portable terminal is not used for communication, it is most commonly applied as a digital camera for capturing an image, and there is an advantage in that it is always portable and can be taken anytime and anywhere.

The digital camera for capturing the still image and the moving image is processed by an electronic signal, and at the moment of capturing, a recording sound signal for recognizing the photographing does not occur at all. There is a fear of infringement.

In order to solve the problems described above, a regulation for generating a recording sound of a predetermined level or more, for example, 65 dB or more is increasingly mandated when shooting with a digital camera. It has a built-in sound recording sound with a dB or more output.

Even in the case of the photographing sound, in order to emphasize the individuality of the user, it searches for various sound signals provided by the service provider, downloads the selected sound signal to the mobile terminal and sets it as a distinctive photographing sound. In some cases, the sound may be downloaded and set as a shooting sound, or a sound signal having a low output level may be used as a shooting sound.

Therefore, there is a need to develop a technology for maintaining the output level according to the definition of the sound signal output to the multimedia portable terminal as the camera photographing sound as described above.

Hereinafter, a photographing sound signal generation method of a portable terminal according to the prior art will be described with reference to the accompanying drawings.

1 is a functional configuration diagram of a general mobile communication system, and FIG. 2 is a flowchart of a method of generating a photographing sound signal of a mobile terminal according to the prior art.

Referring to FIG. 1, the configuration of a general mobile communication system will be described. A mobile station (MS) 10 freely moves within a service area formed by a base station (RAN) 20, while a mobile switching center (MSC) ( 30 is registered in the location and communicates wirelessly with the called party through the communication path formed by the mobile switching center 30.

The call connection, for example, when the mobile terminal 10 dials a unique number of a counterpart to communicate with and transmits a call connection request signal by radio, the base station 20 including the base station controller wirelessly receives a mobile switching center ( 30), the mobile switching center 30 searches the database to check whether the mobile terminal 10 is registered.                         

If it is confirmed by the mobile terminal registered in the search, the dialing number requested for call connection is analyzed, the communication path is set by the corresponding switching process, and the communication proceeds according to the response of the other party connected to the communication path.

The mobile switching center 30 establishes a communication path because the other party is connected to the registered communication network through the public network 50 when the other party is registered in another communication network as a result of the call connection request analysis. Since 50) includes other mobile communication networks, wired communication networks, wireless communication networks, and the Internet, the mobile terminal 10 communicates by making a wireless Internet connection or making a call connection with a registered party of all other communication networks.

The mobile terminal 10 communicates with a counterpart by using only a voice signal, a text message signal, or a communication method using a multimedia signal including a video signal in a voice and text signal.

In order to perform multimedia communication including the video signal, a camera function for capturing a video signal should be added to the mobile terminal 10, and the camera may be an electronic camera for converting the photographed video signal into an electronic signal. It is a digital camera called a digital camera.

The mobile terminal 10 connects to the other party in real time (REALTIME) and occupies a channel (CH: CHANNEL) and communicates with it, in addition to the non-real-time (NON-REALTIME) message method for communicating with the other party by occupying the channel. There is this.

When the mobile switching center 30 requests call connection communication by voice, text, or multimedia message signal from the mobile terminal 10, the mobile switching center 30 applies the input message signal to a server SERVER 40, and the server ( 40) records and stores various input messages and call connection request signals in the allocated area and transmits them to the called party requested by the non-real time processing.

The mobile terminal 10, the time used for the communication is actually very small, and most of the time to carry in preparation for the communication, the utilization rate or utilization rate is lowered, in order to increase the low utilization rate or utilization rate as described above, wireless Internet Various additional functions and additional services such as connection, online game, phone book or phone book, calculator, memo function, radio listening, etc. are provided. In particular, the video signal is transmitted using a camera (CAMERA) that is integrated for multimedia communication. There is a digital camera or digital camera application to shoot.

The digital camera operates electronically and does not generate a recording sound when the electronic camera is photographed, and the photographed party does not recognize that the user is being photographed. Unfair violations of personal privacy, such as use for purposes, occur and become a serious social problem.

In particular, since the multimedia portable terminal 10 is widely distributed at low cost due to mass production and development of related technologies, and is always easily carried anywhere anytime, there is a high possibility of privacy invasion using an integrated digital camera.

Accordingly, when the digital camera function of the multimedia portable terminal 10 is used for purposes other than communication, a sound signal of 65 dB level or more is generated as a recording sound or an intense flash light is generated while recording an image. As a result, it is possible to recognize that the other party is being photographed, and regulations are being tightened to prevent the invasion of privacy in advance.

Hereinafter, a method of generating a photographing sound signal of a portable terminal according to the related art will be described with reference to FIG. 2.

If the determination (S20) is selected to display the photographed sound as a vibration signal, it is set to automatically generate a flash (FLASH LIGHT) when shooting with the camera of the multimedia portable terminal (S30).

In addition, the multimedia portable terminal 10 determines whether to display a photographed sound as a sound signal (S40), and if it is determined that the photographed sound is to be displayed as a sound signal in the determination (S40), the mobile terminal 10 is recorded and stored. The multi-shot sound signal is searched for and selected (S50).

The multimedia portable terminal 10 sets to output the selected sound signal and the flash at the time of shooting (S60), and determines whether to photograph by selecting a subject (S70), and selects the subject specified in the determination (S70). In the case of shooting by shooting, since the sound signal and the flash signal which are the set shooting sound signals are generated, the shooting state is recognized in the vicinity.

In the case of generating the sound signal, there is also a multimedia portable terminal 10 which does not generate flash depending on the model or type of the multimedia portable terminal 10.

The shooting sound signal output when shooting with a digital camera of a multimedia portable terminal as described above defines the generation of a sound signal at a level of at least 65 dB so as to be recognized around the shooting location or by the subject. Prevent illegal shooting that is unfairly infringing.

In order to emphasize the individuality of the user, among the plurality of recording sound signals recorded and stored in the portable terminal 10, a sound signal suitable for a user's taste may be searched and selected and designated as the shooting sound, and the portable terminal 10 may be set. The sound recording signal recorded and stored in the recording) is input and provided from the manufacturer of the mobile terminal 10, and the recording sound signal provided by a professional service provider is secured and recorded and stored by a method such as download. .

As described above, in the method of downloading the photographing sound signal from the service provider, a silent signal in which no sound is output is downloaded as the photographing sound signal (DOWNLOAD) or a sound signal having a low output level is downloaded as the photographing sound signal and selected and output. When set to, when shooting with the digital camera of the mobile terminal 10, it outputs a shooting sound signal of 65 dB level or less.
