BRIEF DESCRIPTION OF THE DRAWINGS The above and other features and advantages of the present invention will be more apparent from the following detailed description taken in conjunction with the accompanying drawings, in which: FIG.

As used herein, terms used in the present invention are selected from general terms that are widely used in the present invention while taking into account the functions of the present invention, but these may vary depending on the intention or custom of a person skilled in the art or the emergence of new technologies. In addition, in certain cases, there may be a term arbitrarily selected by the applicant, in which case the meaning thereof will be described in the description of the corresponding invention. Therefore, it is intended that the terminology used herein should be interpreted based on the meaning of the term rather than on the name of the term, and on the entire contents of the specification.

1 is a diagram illustrating an entire system including a plurality of cameras, a camera management server, and a mobile device according to an embodiment of the present invention. Hereinafter, a mobile device connected to a camera management server and a wired / wireless network will be briefly described with reference to FIG. 1.

First, the plurality of cameras 101, 102, and 103 are designed to perform wired and wireless data communication with the camera management server 100. For example, in a CCTV environment, each camera transmits video data captured through a lens to the camera management server 100 in real time.

According to the related art, the same image is output through a fixed monitor connected to the camera management server 100 or a separate TV. Of course, in the case of having a large screen can be considered to check the current situation of all CCTV cameras, there is a problem that it is difficult to apply the current CCTV system to a device that does not have a large screen. Furthermore, it is a significant load on video data processing speed.

Therefore, as shown in Figure 1, the mobile device 120 according to an embodiment of the present invention is designed to be connected to the network and the camera management server 100 described above. In addition, in consideration of the data processing speed and the convenience of the manager (USER), a new technique for collecting only information on a specific group of cameras is proposed. The mobile device 120 illustrated in FIG. 1 will be described later in more detail with reference to FIG. 2, and the camera management server 100 will be described below in more detail with reference to FIG. 3.

2 is a detailed block diagram illustrating detailed configuration modules of a mobile device according to an exemplary embodiment of the present invention. Hereinafter, referring to FIG. 2, a process of operating detailed configuration modules of a mobile device according to an embodiment of the present invention will be described.

First, the mobile device 220 according to an embodiment of the present invention includes a user interface module 221, a controller 222, a network communication module 223, a memory 224, a video processor 225, and the like. Of course, this is an embodiment, and deleting some modules or adding other modules shown in FIG. 2 as required by those skilled in the art are all within the scope of the present invention.

In addition, the mobile device 220 corresponds to any one of a mobile phone, a smart phone, a tablet PC or a notebook, for example.

The user interface module 221 is designed to receive a signal for selecting a specific mode among at least one or more modes. Embodiments of the mode will be described later in detail with reference to FIG. 4.

The network communication module 223 is designed to transmit a signal for requesting at least one or more camera related data corresponding to the selected specific mode to the camera management server.

The video processor 225 is designed to perform video processing of at least one or more camera related data corresponding to a specific mode received from the camera management server.

The controller 222 controls the processed video data to be output on a screen (not shown) of the mobile device 220.

Therefore, since only video data acquired through a specific group of cameras desired by a user who is an administrator is selectively transmitted and displayed, there is a technical effect of reducing data processing speed and CPU load.

According to another embodiment of the present invention, the controller 222, based on the data received from the camera management server, calculates at least one or more camera number (number) corresponding to a specific mode, and the calculated According to the number of cameras, it is designed to adjust at least one or more of a position or a size at which video data corresponding to each camera is output.

Meanwhile, according to another embodiment of the present invention, the memory 224 is designed to continuously store time information of executing a monitoring service for at least one or more cameras.

When the specific mode corresponds to the first mode, the controller 222 controls the network communication module 223 to request related data only for a camera in which an event occurs between a first time point and a second time point. It is designed to transmit a signal to the camera management server. A more detailed description will be made later with reference to FIG. 6.

When the specific mode corresponds to the second mode, the controller 222 controls the network communication module 223 to transmit location information of the mobile device to the camera management server, and from the camera management server. It is designed to receive camera-related data belonging to a certain area on a limited basis based on the location information. A more detailed description will be described later with reference to FIG. 5.

3 is a detailed block diagram illustrating detailed configuration modules of a camera management server according to an exemplary embodiment of the present invention. Hereinafter, referring to FIG. 3, a management server collecting video data from a plurality of cameras will describe a process of transmitting specific data to a specific mobile device.

The video input unit 310 sequentially outputs video data input from a plurality of cameras in a field or frame unit. The video input unit 310 also serves as a switching unit for switching the video data in field or frame units.

The decoder 320 separates the video data switched by the video input unit 310 in field or frame units into horizontal and vertical synchronization signals, luminance Y, and color difference signals Cb and Cr, and separates analog video signals. Is converted into a digital video signal.

The frame memory 330 temporarily stores the digital video signal converted by the decoder 320 in units of frames. The encoder 340 converts the digital video signal output from the frame memory 330 into an analog video signal, and converts the converted analog video signal into a composite video signal suitable for NTSC or PAL.

The composite video signal output from the encoder 340 is output to the video output unit 350 or the communication module 360 under the control of the controller 370.

The event detector 390 detects whether an event has occurred. The event detector 390 includes a motion detector 391, a synchronization signal detector 392, a sensor 393, and the like.

The motion detector 391 detects motion based on a difference between a current frame and a previous frame with respect to an image signal output from the frame memory 330. For example, the motion detector 391 compares the motion vector of the current frame with the motion vector of the previous frame, calculates a comparison value, and detects that there is motion when the calculated comparison value is greater than or equal to a preset threshold.

When it is determined that there is motion, the motion detector 391 outputs a motion detection result signal to the controller 370.

The sync signal detector 392 detects a sync signal separated from the decoder 320. If the synchronization signal is not detected, the synchronization signal detector 392 determines that the image is lost and outputs an image loss detection result signal indicating the image loss to the controller 370.

The sensor unit 393 is for checking an abnormal state of a set monitoring target region, and is installed at a predetermined position around each surveillance camera, and controls the detection result signal detected by each sensor. )

In addition, the memory 380 is designed to store both an image and a viewpoint information of an event generated by each camera. By designing in this way, it is possible to transmit different result values according to a specific request signal of the mobile device according to an embodiment of the present invention.

Furthermore, the communication module 360 is designed to perform wired or wireless communication with the manager's mobile device. For example, a specific request signal received from the mobile device is received, converted into a corresponding data format corresponding thereto, and the feedback result value is transmitted to the mobile device.

On the other hand, the event described in this specification may be a dictionary meaning commonly used by those skilled in the art in a conventional CCTV camera system, or there is no change in the video picture, but the data of the video picture due to the appearance of any object, person, etc. It may mean that has changed. For example, an event occurrence may be estimated when a video image estimated to be a person stays for a predetermined time or more.

4 is a diagram illustrating a graphical user interface (UI) related to a camera view selection mode according to an embodiment of the present invention. Hereinafter, referring to FIG. 4, a graphical user interface (UI) related to a camera view selection mode according to an embodiment of the present invention will be described.

According to the related art, the current situation of the place where the CCTV camera is installed can be confirmed only through the fixed large TV installed at a certain place where the manager stays. In addition, there has been a problem of not being disclosed about a technique of collecting only a specific group desired by a user.

First, as shown in FIG. 4, the mobile device 420 according to an embodiment of the present invention downloads a related application into a memory to enable the monitoring service described above, or inserts a mobile into an embedded form in an initial manufacturing process. You can also implement a device. In addition, as described above, the mobile device 420 is designed to perform wired and wireless communication with the camera management server in real time.

In addition, the mobile device 420 displays at least one camera view selection mode that a user (manager) can select. Embodiments corresponding to respective modes to be described below are within the scope of the present invention.

The manager wants to pause monitoring and then return to selectively check only events that may have been missed. According to the related art, there is a problem in that several tens of CCTV camera screens are divided into several screens and played one by one. To solve this problem, the mobile device 420 according to an embodiment of the present invention provides a first mode 421.

On the other hand, it can be implemented in two embodiments as a reference for defining the first mode (421). First, based on time information (for example, within 1 hour, within 30 minutes, etc.) directly input by a user (administrator), it collects only CCTV cameras in which an event occurs for a predetermined time. Second, it is also possible to collect only the CCTV cameras in which an event occurs during a predetermined time interval without requiring user input. For example, the mobile device 420 may be implemented by storing time information, which was executed immediately before the monitoring service, in a memory and transmitting the same to a management server.

Mobile device 420 according to an embodiment of the present invention provides a second mode (422). Unlike the technical environment in which only a fixed screen is provided in the related art, an administrator possessing a mobile device 420 according to an embodiment of the present invention checks each CCTV camera screen while patrolling various areas from time to time.

In addition, the manner of implementing the second mode 422 may be separately implemented in two embodiments. A location sensor (eg, a GPS sensor, etc.) mounted on the mobile device 420 is used to transmit geographical information about a location where the manager is currently located to the management server.

At this time, the management server may transmit only information on the CCTV camera installed within a predetermined region (for example, within 1km, within 5km, etc.) based on the geographical information received from the mobile device 420, or the geographical information Based on this, information about the administrative area in which the manager is located may be calculated. For example, an administrator who is currently located in Gwangjin-gu may provide only a CCTV camera screen in Gwangjin-gu, an administrator who is currently located in Gwangjin-dong may provide only a CCTV camera screen in Gwangjin-dong, and an administrator who is currently in Apartment A. You can also provide only CCTV camera screens.

Mobile device 420 according to an embodiment of the present invention provides a third mode (423). For example, when the administrator selects the third mode 423, the CCTV screen is reconfigured based on the serial number assigned to each camera.

However, the serial number defined in the specification may be implemented in both embodiments.

For example, the first embodiment may be designed to correspond to a unique serial number assigned by the manufacturer at the manufacturing stage of the CCTV camera, or the second embodiment may be individually assigned by an administrator of the CCTV system rather than at the manufacturing stage. It can also be designed to mean a series of numbers.

Therefore, when the user (manager) selects the above-described third mode 423, the rearranged CCTV screens are sequentially displayed according to the unique number given by the first embodiment or the second embodiment.

If it is impossible to arrange all the CCTV camera screens on one screen of the mobile device 420, the user may belong to the CCTV cameras belonging to the serial number of the first group and the serial numbers of the second group in a page format. Checking the CCTV camera also belongs to the scope of the present invention.

Mobile device 420 according to an embodiment of the present invention provides a fourth mode (424). Unlike the first mode 421 described above, the fourth mode 424 corresponds to a function of filtering only a CCTV camera that is generating an event based on a current time point.

For example, CCTV system managers need to quickly identify areas that need special action right now. At this time, if you need to check all CCTV camera screens, unnecessary data processing will inevitably occur.

Accordingly, in order to solve the problem, when the fourth mode 424 is selected, the mobile device 420 transmits a request signal only to a camera that is currently generating an event to the CCTV system management server.

In addition, the management server receiving the request signal is designed to detect only a CCTV camera at which an event currently occurs, and transmit related video data to the mobile device 420.

In this design, unnecessary data transmission and processing processes can be omitted, and there is a technical effect that a manager can quickly check only an area that needs monitoring immediately.

Mobile device 420 according to an embodiment of the present invention provides a fifth mode (425). The fifth mode 425 corresponds to a function of selectively selecting only CCTV cameras having the most event count or time accumulated in a database stored in the management server.

Although events have not occurred recently or recently, it is estimated that crimes are likely to occur statistically in areas with cumulative events. Therefore, the administrator in consideration of this point, by selecting the fifth mode 425, there is an advantage that can quickly check only the CCTV camera screen installed in the crime area.

Mobile device 420 according to an embodiment of the present invention provides a sixth mode (426). In the first mode 421, the second mode 422, the third mode 423, the fourth mode 424, and the fifth mode 425 described above, the management server automatically decodes the corresponding CCTV camera. It's about the technology of texting.

On the other hand, the manager may want to check only the CCTV cameras that he or she designates for experience or other reasons. In consideration of such a case, when the administrator selects the sixth mode 426, the mobile device 420 transmits a request signal for a specific CCTV camera. Or, it is also within the scope of the present invention to design a specific CCTV camera group manually selected by the administrator to be pre-stored in the database of the server.

FIG. 5 is a diagram illustrating a process when an example of a specific mode is selected in the camera view selection mode illustrated in FIG. 4. Hereinafter, a process when the second mode is selected in the camera view selection mode illustrated in FIG. 4 will be described as follows.

As described above in FIG. 4, the mobile device 520 displays at least one camera view mode that an administrator can select.

In this case, it is assumed that the manager 530 selects the second mode 522 as shown in the upper part of FIG. 5. As described above, the second mode 522 collects only the CCTV cameras within a certain range from the area where the mobile device 520 is located.

Accordingly, the mobile device 520 receives a current screen of a CCTV camera belonging to a specific area from the management server, and as shown in the lower part of FIG. 5, a plurality of CCTV camera screens 531 of a specific area are displayed. .

As described above, the displayed CCTV cameras may be located within an absolute distance from the mobile device 520, or may be construed limited to cameras within the same administrative area as the administrative area in which the mobile device 520 is located. .

FIG. 6 is a diagram illustrating a process when another example of a specific mode is selected in the camera view selection mode illustrated in FIG. 4. Hereinafter, a process in the case where the first mode is selected in the camera view selection mode shown in FIG. 4 will be described with reference to FIG. 6.

As described above in FIG. 4, the mobile device 620 displays at least one or more camera view modes that an administrator can select.

In this case, it is assumed that the manager 630 selects the first mode 621 as shown in the upper part of FIG. 6. As described above, the first mode 621 performs a function of collecting only a CCTV camera having a recent event determined based on a predetermined criterion regardless of a region where the mobile device 620 is located.

As a result, as shown in the interruption of FIG. 6, the management server primarily displays that a recent event has occurred in a total of four cameras (for example, camera 1, camera 2, camera 5, and camera 7) ( 640). Prior to the user selecting video data, an unnecessary data transmission process may be omitted by providing only a camera number and a serial number.

At this time, the administrator can check only the specific camera desired by the user and check the corresponding video data. However, as shown in the interruption of FIG. 6, the administrator may select an ALL VIEW 641.

Thus, as shown at the bottom of FIG. 6, the mobile device selectively displays only the video data 650 of camera 1, camera 2, camera 5 and camera 7 where a recent event occurred.

However, even at this time, the screen on which the recent event has occurred may be displayed, or the design to display the current screen is all within the scope of the present invention.
