In addition, the present invention is a security menu drive program for setting the user registration, security functions and security-related functions and user registration information, security functions and security-related function setting information in the internal memory or external memory (not shown) of the microcomputer 17, Warning message text / sound data is saved.

At this time, the security function processing unit 16 detects whether the legitimate viewer within a predetermined distance, the legitimate viewer location tracking and the presence of the illegal viewer according to the number of irises or the iris structure, the iris recognition system 16-2. A security function for judging whether or not a legitimate user exists and whether an illegal user exists according to the monitoring result of (16-2), and outputting an image output blocking command or a warning message output command to the microcomputer 17 according to the determination result. The control unit 16-1 is provided.

Here, when the iris recognition system is briefly described, the eye iris pattern having unique characteristics for each person, that is, a unique pattern is formed for each individual within 1 to 2 years of life, is a system using the iris characteristic that does not change for a lifetime. It is much more diverse and impossible to counterfeit, making it the most complete basis for personal identification judgment. The iris recognition system applied to the present invention is a system capable of recognizing basic iris patterns within a relatively long distance even if a person does not have an eye close to the system, and can identify individuals through iris recognition or recognize the number of irises through the number of recognized irises. I can figure out the number.

The control method of an image device having an automatic security function according to the present invention configured as described above will be described with reference to FIGS. 2A to 2C.

First, when the user selects the security menu through the key input unit 18, the microcomputer 17 reads the previously stored security menu driving program, processes the image through the image processing unit 12, and displays it on the display unit 13.

Accordingly, the user performs legal user registration and security function related setting through the key input unit 18. That is, user registration is performed through password input or iris pattern recognition, security function on / off and warning message output type (sound / display) are selected, display mute / warning message is selected, external device Set whether to output warning message.

As shown in FIG. 2A, when the setting is completed, the microcomputer 17 determines whether a predetermined user turns on the power of the video device (S21). When the power is turned on, the security function is turned on. It is determined whether the state (S22).

When the security function is in the 'on' state, it is determined whether the user is registered through at least one of the above-described registration information and the iris pattern comparison or password comparison of the user who 'turned on' the power (S23).

Then, if it is a registered user, it is determined whether the registered user is located in the current viewing space, that is, whether the iris of the user registered by the iris recognition system 16-2 is recognized (S24).

When the registered user is located in the current viewing space, it is determined whether the unregistered user exists in the current viewing space, that is, whether the iris of the unregistered user is recognized by the iris recognition system 16-2 (S25).

Subsequently, if the iris of the unregistered user is not recognized, normal TV operation is performed (S26).

On the other hand, the determination result (S23), if the user 'powered on' is the unregistered user enters the first warning mode (S27). In this case, the process of performing the first warning mode will be described in detail with reference to FIG. 2B.

First, through the display unit 13 or the speaker 15, for example, a TV power 'off' alarm such as "turn off the power because it is an unregistered user" (S31). Subsequently, it is determined whether to transmit the warning message information to the external device according to the above-described security function related setting information (S32). If the A / V alarm is set to 'ON', the A / V alarm information is determined. To transmit to the external device via the A / V output terminal 19 (S33). Then, the TV power is 'off' (S34), and returns to the initial stage 'A'.

On the other hand, if the determination result (S24), if the registered user is not located in the current viewing space, the user may be looking at important personal information and enters the second warning mode (S28). In this case, a process of performing the second warning mode will be described in detail with reference to FIG. 2C.

First, it is determined whether the display alarm is 'on' according to the above-described security function related setting information (S41). Subsequently, when the display alarm is 'on', the display alarm type, that is, the mute / warning message is detected (S42). If it is set to mute, it blocks the current display (S43). If it is set to a warning message, for example, "information may be exposed." And displays a warning message (S45). Meanwhile, if the display alarm is not 'on', it is determined whether the sound alarm is 'on' (S47), and if the sound alarm is 'on', the above-mentioned warning sound is generated (S48). Meanwhile, if the sound alarm is not 'on', it is determined whether the A / V alarm is 'on' (S50), and if the A / V alarm is 'on', the alarm information is transmitted by transmitting the alarm information to the connected external device. The output operation is made (S51). Then, while performing the above-described steps S43, S45, S48 and S51, the security function itself is 'off' or the command to release the alarm of the corresponding step determines whether the alarm is released (S44) (S46) ( If the alarm is released (S49) (S52), a normal TV operation is performed (S53).

On the other hand, the determination result (S25), if the unregistered user is present in the viewing space, and also enters the third warning mode because there is a risk of exposure of important personal information by the unregistered user (S29). In this case, the process of performing the third warning mode is the same as the process of performing the second warning mode, and thus description thereof will be omitted. However, since there is an unregistered person, the content of the warning message may be different.

Although the above-described embodiment has been described mainly for exposing personal information, in order to achieve a viewing restriction purpose such as watching an adult grade broadcasting program of a minor, it can be directly applied without any modification.

According to the present invention, a video device having an automatic security function and a method of controlling the same according to the present invention use an iris recognition system to display a user's personal information while the user's personal information is cleared by a simple setting operation. If you want to watch the screen or trigger an alarm can completely block unwanted information exposure of the user, and there is an effect that can limit the viewing of adult grade broadcasts of minors, such as children.
