Description

Drive control device of video camera

The present invention relates to a driving control apparatus for a video camera, and more particularly, in a video camera capable of zooming and rotating up, down, left, and right, detecting a movement of a subject and moving the zoom value and the up, down, left, and right positions of the video camera to the detected part. The present invention relates to a driving control apparatus of a video camera that can be changed and intensively monitored.

As is well known, Closed Circuit Tele-Vision (hereinafter referred to as CCTV) systems include one or more video cameras that capture surveillance objects, monitors that output video from video cameras, and video cameras. It is composed of a VCR for recording the image captured by the video to be reproduced later. These CCTV systems are currently used for surveillance in banks, factories, and supermarkets, and are installed at major intersections to identify traffic conditions.

Such a conventional video camera has a limitation of the surveillance range according to the installation position, and in order to perform the intensive monitoring of the region to be monitored by overcoming the limitation of the surveillance range, the video can be monitored more precisely. In this case, there is a problem in that the installation cost increases as the number of video cameras increases.

In addition, in the conventional video camera, the image capturing device is moved up, down, left, and right to change the surveillance area, and the zoom value of the image device is changed to zoom in or zoom out the surveillance area to enlarge and reduce the surveillance screen. There is also the ability to add. However, in this case, since the zoom value adjustment and the change of the up, down, left, and right positions of the conventional video camera are controlled by manual operation according to the operator's intention regardless of whether the subject is detected in the surveillance area, this method also takes into account the enlarged aspect of the surveillance range. It is not optimal.

Therefore, the present invention has been devised to solve such a conventional problem, and an object thereof is to provide a driving control apparatus of a video camera that can achieve the maximum surveillance effect by using the same number of video cameras.

In addition, another object of the present invention is to provide a drive control apparatus of a video camera that can detect the movement of the subject in the surveillance region to monitor the portion where the movement is detected.

In order to achieve the above object, the driving control apparatus for a video camera according to the present invention is a driving control apparatus for a video camera capable of adjusting a zoom value and an imaging angle of a video camera photographing a surveillance region. A motion detection unit for detecting the motion detection unit and a control unit for changing the zoom value and the imaging angle of the video camera so as to centrally monitor a portion where the movement of the subject is detected when the motion is detected. Characterized in that provided.

In addition, in the driving control apparatus of the video camera according to the present invention, the motion detector is characterized by detecting the movement of the subject in the surveillance area by comparing the previous screen and the current screen by the video signal provided from the video camera.

Hereinafter, the driving and action effects according to the preferred embodiment of the drive control apparatus for a video camera of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic block diagram of a CCTV system to which a driving control apparatus for a video camera according to the present invention can be applied. As shown in FIG. 1, the CCTV system to which the present invention is applied includes a zoom lens controller 30 and a video camera 10 for adjusting zoom in and zoom out of the zoom lens 20. Up and down left and right rotation controller 40 for rotating left and right, a signal processor 50 for signal processing the video signal output from the video camera 10, and a monitor for outputting the output signal of the signal processor 50 on the screen 70 and the motion detection unit 60 for detecting the motion by comparing the previous and current video signals input from the video camera 10 and the motion detection unit 60 based on data provided from the motion detection unit 60. When it is determined and there is motion, the controller 80 is configured to change up, down, left, and right positions of the video camera 10 and to zoom in the zoom lens 20 to monitor the detected part.

In the above-described configuration, the zoom lens controller 30 includes a zoom motor for adjusting the zoom value by rotating the zoom lens 20, and the vertically and horizontally rotating controller 40 vertically rotates the vertical rotation table of the video camera 10. And a left and right rotating motor for rotating the left and right rotating tables, and a vertical rotating motor driving unit and a left and right rotating motor driving unit controlling their driving according to the control signal input from the controller 80.

The operation of the driving control apparatus of the video camera according to the present invention having such a configuration will be described below.

First, the surveillance object region captured by the video camera 10 is divided into four virtual zones, and the video camera 10 for intensively photographing the four divided zones at the beginning of the driving of the video camera 10. The imaging angle according to the zoom value and the up, down, left, and right position values is set in advance.

Then, the video camera 10 is driven to capture an area to be monitored, and display the surveillance area captured by the signal processing unit 50 on the monitor 70, and the motion detector 60 is provided from the video camera 10. By comparing the previous picture and the current picture by the video signal to detect whether the movement in the surveillance area is detected.

The controller 80 determines whether the subject moves in the surveillance area based on the data input from the motion detector 60, and when the movement of the subject is detected, the controller 80 virtually divides the motion detected area, that is, the initial screen. The area in which the motion is detected is determined from the four areas.

In addition, when it is determined that the area where the motion is detected, the controller 80 zooms in the zoom lens 20 of the video camera 10 so as to concentrate the monitoring of the area where the motion is detected, and adjusts it to a preset imaging angle. A control signal is output to the zoom lens controller 30 and the up, down, left, right rotation controller 40 so as to change the up, down, left, and right values of (10).

Meanwhile, the controller 80 adjusts the zoom value and the imaging angle of the zoom lens 20 to monitor the area where the motion is detected, and thus the motion is not detected according to the comparison result of the previous and current screens by the motion detector 60. If it is determined that the imaging angle is changed according to the vertical, horizontal, left and right position adjustment of the video camera 10 so as to capture the area to be initially monitored. In addition, the zoom lens 20 is zoomed out to be driven at the initially set zoom value.

As described above, the driving control apparatus for a video camera according to the present invention includes a motion detection unit for detecting a motion in the surveillance area by comparing the current and previous screens of the surveillance area captured by the video camera. Allows you to adjust the imaging angle and zoom value of the video camera so that the part can be monitored.

Therefore, in order to intensively monitor the area to be monitored by the driving control apparatus of the video camera according to the present invention, it is necessary to adjust the zoom value of the video camera and change the imaging angle by adjusting the zoom value of the video camera without additional installation of a separate video camera. There is an advantage that can increase the monitoring effect because it can be monitored centrally. In addition, a motion detection unit that automatically detects the movement of the area to be monitored is controlled to control the driving of the video camera to intensively monitor the part where the movement of the subject is detected. Accurate monitoring is possible.
