The present invention relates to a mobile communication terminal having a camera security function, and in particular, 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. The present invention relates to a mobile communication terminal having a camera security function for improving security.                         

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.

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.

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.

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.

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.

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 a terminal encrypted through the terminal information encryption unit into an infrared or RF signal according to a signal transmitting end; And a signal output unit for radiating the signal converted by the information converter in the same direction as the camera photographing direction.

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.

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

1 is a block diagram showing a configuration of a mobile communication terminal having a camera security function according to the present invention, the 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.

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.

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.

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.

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.

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.

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.

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.

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.

At this time, 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 to generate it.

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.

In this case, the encrypted terminal identification information is read only by an authorized government agency, so as to protect the privacy of individual users of the camera terminal, and by storing identification information of the terminal which attempted unauthorized shooting, further evidence It can be used as a material.

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.
