이동 통신 단말기는 점차 다양한 부가 기능이 첨부되면서, 보급형을 제외하고 최근에 출시되는 대부분의 이동 통신 단말기는 카메라 기능이 첨부되는 것이 일반적이다.As the mobile communication terminal is gradually attached to various additional functions, most of the recently released mobile communication terminals except for the entry type are generally attached with a camera function.

상기와 같이 카메라 기능이 첨부되면서 화상 통화가 가능하게 되었으며, 그 성능이 점차 향상됨에 따라 해상도가 높아지고 동영상 촬영까지 가능하게 되면서, 일반 카메라나 캠코더의 대체 수단으로 충분히 활용할 수 있게 되었다.As the camera function is attached as described above, the video call becomes possible, and as the performance is gradually improved, the resolution is increased and the video is also possible, and thus can be sufficiently utilized as an alternative means of a general camera or a camcorder.

그러나, 상기와 같은 기능은 일상 생활에서는 대단히 유익한 기능으로 작용하지만, 산업 현장이나 보안을 요하는 지역에서는 오히려 보안을 위협하는 수단이 되었다. 즉, 카메라 단말기가 널리 보급되면서 사생활 침해 및 기업 비밀보호 등의 차원에서 특정한 상황하에서는 카메라 단말기에 의한 촬영을 제한해야 한다는 주장이 제기되고 있다. However, the above functions are very useful functions in daily life, but have become a means of threatening security in industrial sites or areas requiring security. In other words, as camera terminals become widespread, it has been argued that camera shooting should be restricted under certain circumstances in terms of privacy infringement and corporate secret protection.

그러나, 현재로서는 카메라 단말기의 사용을 검출할 만한 특별한 장치나 수단이 구비되어 있지 않은 상태이기 때문에, 보안을 요하는 지역에서는 카메라 단말기의 휴대 자체를 금지하는 등, 사용자의 불편이 점차 증가하고 있는 상황으로, 단말기 제조업자로써는 보안 지역이 증가함에 따른 사용자의 불편을 해소하고, 보안성도 향상시킬만한 대책을 마련해야 하는 문제점이 있다.However, since there are no special devices or means for detecting the use of the camera terminal at present, the user's inconvenience is gradually increasing, such as prohibiting the carrying of the camera terminal itself in an area requiring security. As a terminal manufacturer, there is a problem in that a countermeasure to solve the inconvenience of the user as the security area is increased and to provide a countermeasure to improve the security is also provided.

따라서, 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 창출한 것으로, 단말기에서 카메라 촬영 방향과 동일한 방향으로 소정의 신호를 방사하도록 함으로써, 촬영 제한구역에서 이 신호를 검출하여 경고음 등을 발생하여 해당 지역의 보안성을 향상시킬 수 있도록 하는 카메라 보안 기능을 구비한 이동 통신 단말기를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and by emitting a predetermined signal in the same direction as the camera shooting direction in the terminal, by detecting this signal in the shooting restricted area to generate a warning sound, etc. It is an object of the present invention to provide a mobile communication terminal having a camera security function to improve the security of the area.

이와 같은 목적을 달성하기 위한 본 발명은, 카메라 기능을 갖는 이동 통신 단말기에 있어서, 카메라의 작동 시 이를 검출하는 카메라 작동 검출부와; 상기 카메라 작동 검출부를 통해 카메라 작동이 검출될 경우, 카메라 단말기의 사용자 식별이 가능한 정보를 암호화하는 단말기 정보 암호화부와; 상기 단말기 정보 암호화부를 통해 암호화된 단말기의 식별 정보를, 적외선 또는 RF 신호등 신호 송출수단에 따른 적절한 신호 형태로 변환하는 정보 변환부와; 상기 정보 변환부를 통해 변환된 신호를 카메라 촬영방향과 동일한 방향으로 방사하기 위한 신호 출력부를 포함하여 구성한 것을 특징으로 한다.In order to achieve the above object, the present invention provides a mobile communication terminal having a camera function, comprising: a camera operation detection unit for detecting a camera operation; A terminal information encryption unit for encrypting user identifiable information of the camera terminal when the camera operation is detected through the camera operation detection unit; An information conversion unit for converting identification information of the terminal encrypted through the terminal information encryption unit into an appropriate signal form according to signal transmission means such as an infrared ray or an RF signal; And a signal output unit for radiating the signal converted by the information converter in the same direction as the camera photographing direction.

본 발명은 카메라 단말기에 카메라 촬영 방향과 동일한 방향으로 소정의 신호를 방사할 수 있도록 함으로써, 보안을 요하는 지역에서 카메라 촬영을 제한하고자 할 경우, 상기 신호를 검출할 수 있도록 하는 장치를 구비함으로써, 사용자가 단말기를 휴대하더라도 카메라 촬영은 제한하면서 통화는 가능하게 하여 사용자의 편의성 및 보안 지역에서의 보안성도 충족시킬 수 있도록 하는 이동 통신 단말기의 제공을 그 요지로 한다. According to the present invention, by providing a camera terminal to emit a predetermined signal in the same direction as the camera shooting direction, by providing a device for detecting the signal when the camera shooting is to be restricted in an area requiring security, Even if a user carries the terminal, the main point of the present invention is to provide a mobile communication terminal which enables the user to make a call while limiting camera photography so as to satisfy user convenience and security in a secure area.

이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described.

도1은 본 발명에 따른 카메라 보안 기능을 구비한 이동 통신 단말기의 구성을 보인 블록도로서, 카메라용 이동 통신 단말기에서 카메라의 작동 시 이를 검출하는 카메라 작동 검출부(100)와, 상기 카메라 작동 검출부를 통해 카메라 작동이 검출될 경우, 단말기의 전화번호 또는 SIM 카드의 정보 및 촬영시간 등 카메라 단말기의 사용자 식별이 가능한 정보를 암호화하는 단말기 정보 암호화부(101)와, 상기 단말기 정보 암호화부를 통해 암호화된 식별 정보를 적외선 또는 RF 신호등으로 변환하는 정보 변환부(102)와, 상기 정보 변환부(102)를 통해 변환된 신호를 카메라 촬영방향과 동일한 방향으로 방사하기 위한 신호 출력부(103)를 포함하여 구성한다.1 is a block diagram showing a configuration of a mobile communication terminal having a camera security function according to the present invention, a camera operation detection unit 100 for detecting the operation of the camera in the camera mobile communication terminal, and the camera operation detection unit When the camera operation is detected through the terminal information encryption unit 101 for encrypting the user identification information of the camera terminal, such as the phone number of the terminal or the information and shooting time of the SIM card, and the identification encrypted by the terminal information encryption unit And an information conversion unit 102 for converting information into an infrared or RF signal, and a signal output unit 103 for radiating a signal converted through the information conversion unit 102 in the same direction as the camera photographing direction. do.

여기서, 상기 카메라 작동 검출부(100)는 사용자가 단말기 메뉴를 조작하여 카메라 모드로 전환한 후, 셔터 역할을 하는 키 버튼을 누를 경우 이를 검출하는 역할을 한다.Here, the camera operation detection unit 100 detects this when the user switches to the camera mode by operating the terminal menu and presses a key button serving as a shutter.

다음, 상기 단말기 정보 암호화부(101)는 단말기의 전화번호 또는 SIM 카드의 정보 및 촬영시간 등 카메라 단말기의 사용자 식별이 가능한 정보를 암호화하는 것으로, 그 정보들은 촬영 제한 지역에서 단말기 휴대를 허용할 경우 지정된 사용자의 단말기에 대해서만 휴대할 수 있도록 하기 위한 것이다. 즉, 사용자와 단말기의 사용자 식별 정보가 동일한 경우에만 휴대를 허용하고, 혹시 무단 촬영이 이루어질 경우 그 사용자를 검출할 수 있도록 하는 용도로 사용할 수 있다.Next, the terminal information encryption unit 101 encrypts user identifiable information such as a phone number of the terminal or information of the SIM card and a shooting time, and the information is used when allowing the terminal to be carried in a restricted area. It is intended to be able to carry only a terminal of a designated user. That is, the portable terminal can be used only when the user identification information of the user and the terminal are the same, and can be used to detect the user when unauthorized photographing is performed.

다음, 상기 정보 변환부(102)는 상기 단말기 정보 암호화부를 통해 암호화된 단말기 식별 정보를, 적외선 또는 블루투스 등 신호 송출수단에 맞는 적절한 신호 프로토콜로 변환한다.Next, the information conversion unit 102 converts the terminal identification information encrypted through the terminal information encryption unit into an appropriate signal protocol suitable for signal transmission means such as infrared or Bluetooth.

다음, 상기 신호 출력부(103)는 상기 신호 송출수단에 맞는 형식으로 변환된 단말기 식별 정보를, 방향성 안테나 또는 적외선 송출수단에 따라 카메라 촬영방향과 동일한 방향으로 방사한다.Next, the signal output unit 103 radiates the terminal identification information converted into a format suitable for the signal transmitting means in the same direction as the camera photographing direction according to the directional antenna or the infrared transmitting means.

상기와 같이 본 발명은 카메라 보안을 위한 수단을 단말기 내부에 구비함으로써, 촬영을 제한하기 위한 보안 구역에서는 상기 보안 수단을 적절히 이용하여 보안성을 향상시킬 수 있도록 한다.As described above, the present invention includes a means for securing the camera inside the terminal, so that security can be improved by appropriately using the security means in a security zone for limiting photographing.

예컨대, 현재 촬영 제한이 요구되는 보안 지역에서는 보통 검색대를 통과하여 진입하도록 되어 있으며, 그 과정에서 핸드폰이나 프로피 디스켓, 컴퓨터와 같은 장치를 검출하여 휴대하지 못하도록 하고 있으며, 허가된 경우에 한해서만 휴대가 가능하도록 하고 있다.For example, in security areas where current shooting restrictions are required, users are usually required to enter through a checkpoint, and in the process, devices such as mobile phones, profile diskettes, and computers are not detected and carried. I'm making it possible.

따라서, 종래의 경우에 카메라 단말기를 통한 촬영을 검출하기 위한 수단이 없었기 때문에, 카메라 단말기의 경우 휴대할 수 없기 때문에, 사용자는 보안 지역에서 전화 통화조차도 쉽게 할 수 없는 불편이 있었으나, 본 발명을 적용할 경우에는 휴대가 가능하게 되므로 사용자의 편의성이 향상되고, 촬영 제한 구역에서는 보안성도 향상시킬 수 있게 되었다.Therefore, in the conventional case, since there is no means for detecting the shooting through the camera terminal, since the camera terminal is not portable, there is a inconvenience that a user cannot easily make a telephone call even in a secure area, but the present invention is applied. In this case, the user's convenience can be improved since the portable device can be carried, and the security can be improved in the restricted shooting area.

즉, 검색대 통과 시 단말기에 보안 수단이 구비되어 있음을 관리자에게 알리고, 단말기 식별 정보를 등록할 경우 휴대가 가능하도록 하는 것이다. 이렇게 단말기 식별 정보를 등록한 단말기는 도2에 도시된 바와 같이 촬영 제한 구역에서 카메라 기능을 이용하고자 할 경우, 경보음 출력과 함께 그 단말기 식별 정보가 바로 검출되므로, 무단 촬영을 충분히 방지할 수 있기 때문에 휴대를 허용하는 것이다.That is, when passing through the search station to inform the administrator that the terminal is provided with a security means, when registering the terminal identification information is to be portable. When the terminal registered with the terminal identification information is to use the camera function in the shooting restricted area as shown in Fig. 2, since the terminal identification information is detected immediately along with the alarm sound output, unauthorized shooting can be sufficiently prevented. It is to allow carrying.

이때, 상기 촬영 제한 구역에서는 본 발명이 적용된 단말기에서 송출하는 신호를 수신하기 위해 전방향 안테나(Omni-directional Antenna)와 블루투스 등의 신호를 복조하는 장치와 수신된 단말기 식별 정보를 저장하고 경보음을 발생하는 장치를 구비해야 할 것이다.In this case, the photographing restricted area stores a device for demodulating signals such as omni-directional antenna and Bluetooth and received terminal identification information in order to receive a signal transmitted from the terminal to which the present invention is applied. You will have to have a device that generates.

또한, 본 발명을 적용할 경우 장점은 촬영금지 대상에서 특정거리 내에서만 촬영이 제한되게 할 수도 있다는 점으로, 카메라 단말기의 신호 출력부로부터의 송신출력을 수신부에서 측정할 때 수신된 신호의 세기를 측정하면, 카메라 단말기와 촬영제한 지점과의 거리도 계산이 가능하며, 이를 이용하면 촬영제한 지점의 범위도 조정이 가능할 것이다.In addition, the advantage of applying the present invention is that the shooting may be limited only within a certain distance from the subject to prohibit shooting, the strength of the received signal when measuring the transmission output from the signal output of the camera terminal at the receiver When measured, the distance between the camera terminal and the shooting limit point can be calculated, and using this, the range of the shooting limit point can be adjusted.

이때, 상기 암호화된 단말기 식별 정보는 공인된 정부기관 등에서만 판독하게 함으로써, 카메라 단말기의 사용자 개개인의 사생활을 보호할 수 있도록 하는 것이 바람직하며, 무단 촬영을 시도한 단말기의 식별 정보를 저장함으로써, 추후 증거자료로도 사용할 수 있도록 하는 효과가 있다.In this case, the encrypted terminal identification information may be read only by an authorized government agency, so as to protect the privacy of individual users of the camera terminal. It can be used as a material.

이상에서 설명한 바와 같이 본 발명 카메라 보안 기능을 구비한 이동 통신 단말기는, 단말기에서 카메라 촬영 방향과 동일한 방향으로 소정의 신호를 방사하도록 함으로써, 촬영 제한구역에서 이 신호를 검출하여 경고음 등을 발생하여 해당 지역의 보안성을 향상시킬 수 있도록 하는 효과가 있다.As described above, the mobile communication terminal equipped with the camera security function of the present invention causes the terminal to emit a predetermined signal in the same direction as the camera photographing direction, thereby detecting the signal in the shooting restricted area and generating a warning sound or the like. There is an effect to improve the security of the area.

도 1은 본 발명에 따른 카메라 보안 기능을 구비한 이동 통신 단말기의 구성을 보인 블록도.1 is a block diagram showing the configuration of a mobile communication terminal with a camera security function according to the present invention.

도 2는 본 발명을 적용하여 촬영 제한 구역에서 무단 촬영을 검출하는 방법을 설명하기 위한 예시도.Figure 2 is an exemplary view for explaining a method for detecting unauthorized shooting in the shooting restricted zone by applying the present invention.
