Description

Camera with motion detection recording function {SECURITY CAMERA}

The present invention relates to a camera having a motion detection recording function, and more particularly, to a camera that is improved to capture and record by zooming in to detect a motion to identify an object.

In recent years, not only homes and offices, but also roads, alleys, parking lots, and automobiles are equipped with cameras for surveillance purposes, and they are used as important materials for screening sisbibi.

The camera as described above has been developed and used in various types, but is generally as shown in FIG. 4.

The camera 1 includes a photographing element 2 in a camera body having various shapes and shapes, is installed in a photographing (monitoring) area, and an image signal applied from the photographing element 2 installed in the camera 1 It is applied to the control part 3.

The control section 3 is configured to include a transmission section 5 for storing the applied video signal in the recording medium 4 of the management destination or providing the video information to the monitor or database of the management destination.

In the operation for determining the photographing range of the photographing element 2, the photographing range or the photographing distance can be set by artificially manipulating the zoom lever installed at the rear of the main body of the camera 1 by using a hand or a tool.

Cameras to which the prior art as described above is applied do not have a zoom function when the zoom lever is set when the camera is first installed, and thus only a function of performing photography is performed within a set shooting range.

For this reason, only a focal length set at an initial stage is set, and since a single camera is used for the purpose of capturing a wide area as much as possible, photography of a type close to a wide angle is performed.

Therefore, not only can the recorded video not be clear, but in case of an actual event (abnormal situation), the video in question can be taken, but the image quality is not clear, and it is difficult to shoot in close proximity, so It is difficult to read, which causes a decrease in the usability.

As described above, in the case of analyzing a specific event in order to utilize the image photographed at a wide angle, if only a corresponding portion of the recorded area information is enlarged, the recognition rate is very low due to a mosaic phenomenon or a deterioration of image quality, and thus practical use is difficult.

For this reason, even when an abnormal situation occurs in the photographing area and the photographing state is taken, it becomes difficult to perform the original function of the camera because it is not easy to identify not only the person of the photographing object but also a vehicle or a character.

In addition, when the camera's zoom lever is set to the close-up mode in order to improve image quality through close-up photography, one or more cameras must be installed at the installation site, which is expensive and excessively expensive. Problems are occurring.

Accordingly, in the present invention, to solve the problems described above, the image information photographed by the photographing device is transmitted to the management station through the control unit to be stored in the storage medium of the management station or reproduced through the monitor, and the control unit is configured to A receiving unit for receiving the captured image information, a recording unit for recording the received image information, a transmitting unit for providing the recorded image information to a management station, and an operation for continuously shooting an image of an installation region through the photographing device A camera comprising a section;

The control unit detects and tracks an abnormal situation such as a movement or an event of a shooting area, switches to a zoomed-in state, and captures and stores the event situation with clear image quality. It is possible to achieve the purpose of facilitating the situation resolution through situation determination and tracking.

The present invention can detect the abnormal situation in the camera to capture and provide a clear image in the zoomed-in state by sticking to the original function of the camera to provide the ease of tracking and analysis to increase the usability and increase the monitoring efficiency, etc. The invention has various effects.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary view showing a camera having a motion sensing recording function to which the technique of the present invention is applied, FIG. 2 is a block diagram showing a camera having a motion sensing recording function to which the technique of the present invention is applied, and FIG. A description will be given as a control block diagram of a camera having a motion sensing recording function to which the technique is applied.

In the camera 100 having a motion detection recording function to which the technique of the present invention is applied, the image information photographed by the photographing element 101 is transmitted to the management unit 103 through the control unit 102 and the storage medium of the management unit 103. Storage 104 or playback through monitor 105.

In the present invention, the control unit 102 is improved to detect and track when an abnormal situation such as a motion or an event occurs in the shooting area, switch to a zoom-in state, and capture and use the event situation in clear image quality. It is done.

The control unit 102 provides the receiving unit 106 for receiving the image information captured by the photographing device 101, the recording unit 107 for recording the received image information, and the recorded image information to the management unit 103. Transmitting unit 108 is provided.

Naturally, the receiving unit 106 or the recording unit 107 has an A / D converter for digitizing the analog type image information captured by the photographing element 101.

The photographing element 101 allows the operation unit 109 to continuously photograph an image of an installation area in everyday situations, and to perform precise imaging when motion of a person, car, or other object is detected within the photographing area. Do it.
