Surveillance monitor system using the ISM function according to the present invention is an external image device capable of capturing the movement of the external object, and by using the ISM function for the image input through the external image device to detect and display the movement of the external object Characterized in that it comprises a display device.

In addition, the display device may be replaced by a PDP set or an LCD set.

Surveillance monitoring method using the ISM function according to the present invention is compared to the sum of the brightness of the previous screen and the sum of the brightness of the current screen input and displayed through the external video device is recognized as the display of the same screen, otherwise In the step of recognizing as a video, and in the case of recognizing a video in the step characterized in that it comprises the step of generating an ISM release signal, the recognition to the microcomputer to generate a warning signal.

In the generating of the warning signal, the warning signal may further include storing a screen of the moment in a memory and performing a warning command of a warning sound or a warning phrase.

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

3 is a block diagram showing the configuration of a monitoring monitor system according to the present invention.

As shown in FIG. 3, the surveillance monitor system according to the present invention is an external image device 201 capable of capturing and capturing a motion of an external object, and an ISM for an image input through the external image device 201. It is configured to include a display device 210 for detecting and displaying the movement of the external object by utilizing a function.

Here, the display device 210 compares the sum of the brightness of the current screen and the previous screen brightness transmitted from the external video device 201 from the external video device 201 to the sum of the current screen brightness and the previous screen brightness. If the sum does not match, the comparator 203 for generating an ISM release signal, the micom 204 for generating a warning signal by recognizing the ISM signal generated through the comparator 203, and the micom ( The memory 205 for storing the screen at the moment when the warning signal is transmitted through the 204, the PDP monitor 206 for displaying the screen stored in the memory 205, and the microcomputer 204 It is composed of an audio unit (not shown) for notifying a message of the warning signal with a warning sound.

In particular, the surveillance monitor system according to the present invention applies an ISM (Image Sticking Method) function of a plasma display panel (PDP) module to detect movement of an external object, and when there is an object moving in a control area, the brightness of the entire screen is increased. In this case, the ISM function is released, and the panel's ISM release signal is received from the microcomputer (204: U-COM) of the display device through serial communication that is being used to warn the OSD on the screen or to the external warning device. It is a security notification device that sends a warning signal.

This allows the watcher to know the movement by warning text or warning sound when the movement is detected without monitoring the monitor in the control area, and what object moved if the screen still function is turned on at this moment? It can be detected.

Here, the ISM function refers to the afterimage when the same screen is displayed on the display device for a certain period of time. To prevent this, the total brightness displayed on the panel is calculated, and the brightness is decreased when the sum of the brightness does not change within a certain range. It is a function that raises the brightness to the original state when the brightness and the sum of brightness change.

Since the ISM function is applied to the LCD (Liquid Crystal Display) module, the same effect can be obtained in the case of the LCD set in which the PDP monitor 206 displaying the warning message in the display device 210 is replaced with the LCD monitor. Can be.

4 is a perspective view showing the configuration of a monitoring monitor system according to the present invention.

Referring to FIG. 4, it can be seen that the surveillance monitor system according to the present invention is composed of an external video device 201 and a display device 210 only, which is easier than the conventional system.

5 is a flowchart illustrating a surveillance monitoring process in the surveillance monitor system according to the present invention.

Currently, the PDP module adopts an ISM function that gradually decreases the brightness in this case in order to prevent afterimages when the same screen is displayed for a long time. Referring to FIG. 5, a monitoring and monitoring process using the ISM function will be described.

First, an external image device for detecting a movement of an external object is operated (S501).

Subsequently, the sum of the brightnesses of the current screen (N-th screen) input and displayed through the external video device is measured (S502), and the sum of the brightness of the current screen (N-th screen) and the previous screen (N-1 th screen). ) Is compared with the sum of the brightnesses (S503).

Here, when the sum of the current screen brightness is the same as the sum of the previous screen brightness, it is recognized as a display of the same screen, and when the comparison value of the sum is different, it is recognized as a video.

Therefore, if the sum of the screen brightness is the same, the process of storing the sum of the brightness of the current screen (Nth screen) and continuously comparing the sum of the brightness of the screen is repeated, but if the sum of the screen brightness is not the same, the serial Communication generates an ISM release signal to advance the process of notifying the intrusion of an external object.

When the ISM release signal is generated (S505), the microcomputer recognizes it and generates a warning signal (S505).

When a warning signal is generated from the microcomputer, the security screen is terminated by storing the screen at the time of warning in the memory and informing the presence of an intruder by generating a warning phrase or a warning sound in the screen stored in the memory.

As such, the present invention does not have a separate process of detecting a moving object in the restricted area, and the existing PDP or LCD is instantaneously using the point that the sum of the total brightness changes when motion is captured through the same brightness comparison with the ISM algorithm. When generating release signal, U-COM recognizes and generates warning signal to monitor and monitor.

6 is a view showing a warning or warning sound generation of the monitoring monitor system according to the present invention.

Referring to FIG. 6, it can be seen that the PDP or LCD screen of the monitoring and monitoring system according to the present invention displays an alarm word or generates an alarm sound on the OSD when an abnormal object is detected in the control area.

7 is a diagram illustrating an additional menu OSD for surveillance monitoring in the present invention.

As shown in FIG. 7, in order for the present invention to function as a monitoring system, the PDP or LCD should add a separate menu OSD as shown in FIG. 7 to the existing menu OSD, and the additional menu selection process will be described below.

First, select the alarm that controls the monitoring function from the special menu and decide whether to execute the warning mode or the monitoring function by selecting OSD, Buzzer, OSD / BUZZER, or OFF in the alarm mode. Phrase or beep).

In addition, the view stores the screen of the moment when the microcomputer receives the ISM release signal from the module in the memory, and displays the screen at the time of on selection and returns to the original screen at the time of off selection.

As described above, the monitoring monitor system according to the present invention is to apply the ISM function of the PDP or LCD module to the detection of the movement of an external object, the monitor moves by a warning phrase or a warning sound without monitoring the monitor in the control area. If you turn on the screen still function at this moment, you can detect which object has moved.

In addition, it is possible to easily configure the monitoring monitor system using only a general external video input device (video camcorder, etc.) and a display device without configuring a separate device or device for detecting an external object motion.
