7 to 9 are diagrams for explaining embodiments of a scenario encoding and display method according to the present invention. In the encoding according to the present invention, the administrator sets one or more important video areas through the input means 700 while viewing the video data displayed through the display apparatus 600, and the resolution of the corresponding important video areas and the resolution of the general video areas. The scenario is to configure it differently.

First, FIG. 7 is a diagram illustrating displaying of image data 610 having a general high definition HD capacity. The image data 610 illustrated in FIG. 7 has a resolution of 1920 * 1080 in case of Full HD. At this time, the resolution is about 2 million. The transmission speed required to transmit such high-definition video data with 2 million resolution is 2Mbps for low quality, 4Mbps for medium quality, and 8Mbps for the highest quality.

FIG. 8 illustrates a first embodiment of a method of setting an important video area in the image data 610 shown in FIG. 7 and a method displayed on the display apparatus 600. In FIG. 8, a plurality of first to third important image areas 620, 630, and 640 are set in the image data 610 image area. In this case, it can be seen that the area excluding the important video area is a general video area, and the important video area is a part of the video area of the image data.

Can be.

Meanwhile, in FIGS. 8 to 9, the important image area is displayed as a rectangle. Of course, the important video region depends on input of setting data for setting the important video region, and there is no need to specifically limit the shape to a circle, oval, polygon, or shape in addition to the rectangle. This means that the user can set variously according to the way of managing the important video area.

10 is a flowchart for explaining a video data processing method of a network camera system according to the present invention. In the image data processing method using the network camera system according to the present invention, first, an initial image transmitted from the network camera apparatus is displayed on the display apparatus (S100). Such an initial image is an image encoded with a uniform resolution.

Then, the user sets a predetermined region of the initial image as the important image region of the first resolution on the control server device 400 through an input means such as a keyboard or a mouse, and sets the other region or the entire image region to the first resolution. In operation S120, setting data for setting a general video area having a low second resolution is input from the user. The setting data includes at least one of first resolution setting data, position data, size data, and time zone data that can be activated in the important video region. In addition, the second resolution setting data of the general video region is included. The important video region may include setting data for encoding in color and the general video region for encoding in monochrome.

Then, the control server device 400 transmits the setting data to the network camera device (S140).

Accordingly, the network camera apparatus encodes the image data being captured based on the setting data (S160).

Subsequently, the video data encoded at different resolutions is transmitted to the control server device 400 (S180).

The control server device 400 transmits the image data to the display device 600 (S200). At this time, the control server device 400 stores the video data in the storage means.

In operation S220, the display apparatus 600 displays corresponding image data. Here, the display method may display only the size or resolution of the important video region by overlaying the important video region on the general video region, or by dividing the important video region and the general video region. In addition, the important video area may be displayed in color, and the general video area may be displayed in a single color.

11 is a flowchart for explaining a method for operating a network camera system according to the present invention. In the method for operating a network camera system according to the present invention, as shown in FIG. 11, the network camera apparatus 100 encodes captured image data with preset data to differently encode the resolutions of the important video region and the general video region. 400) (S300).

On the other hand, the first control means 150 of the network camera device 100 determines whether the abnormality is detected in the sensing means (S320).

If the determination result (S320), the abnormality is detected, the first control means 150 analyzes the detected abnormality (S340). Such an analysis may include, for example, detecting a movement of a person or a vehicle, detecting an opening of a door, and detecting a fire in which a fire occurs.

If it is detected in the analysis result (S340) that the opening door is detected, it is determined whether the vehicle that is the abnormality detection target or the person is detected while imaging the abnormal detection direction (S360). On the other hand, even when a fire occurs, the movement of a person or a vehicle is detected. In such cases, arsonists, true talkers, suspects and witnesses can be secured.

Then, in the case of a person according to the analysis result (S340) and the determination result (S360), the corresponding area according to the moving direction of the person is encoded as an important video area and transmitted to the control server device (S400). At this time, the area in which the person is present is the important video area and the area in which no person is present is the general video area.

On the other hand, it is determined whether the face recognition is possible while capturing the image (S420). If the face recognition is possible, the face region is zoomed in or photographed, or the face region is encoded into the important video region and transmitted to the control server device (S440).

As described above, setting, encoding, and transmitting an important video region for a person or a face is continued until the person exists in the person area (S460).

In addition, in the case of a vehicle according to the analysis result (S340) and the determination result (S360), the corresponding area according to the moving direction of the vehicle is encoded as an important image area and transmitted to the control server device (S500). At this time, the area in which the vehicle is present is an important image area and the area in which no vehicle is present is the general image area.

On the other hand, it is determined whether the vehicle number recognition is possible while capturing the image (S520). If the vehicle number recognition is possible, the vehicle number area is zoomed in and photographed or the vehicle number area is encoded as an important image area and transmitted to the control server device ( S540).

As described above, setting, encoding, and transmitting the important video region for the vehicle or the vehicle number is continued until the vehicle exists in the imaging region (S560).

If a person or a vehicle does not exist within the imaging range, the first control means 150 returns to preset data and encodes different resolutions of the important video area and the general video area with the preset data, thereby controlling the server 400. Transmit to (S600).
