The present invention relates to a method for allowing a user to set privacy masking even for a surveillance camera that cannot be remotely controlled.

In the case of a surveillance camera capable of remote control, a remotely located user can select and specify a masking block of a predetermined size through an input device such as a personal computer, so that the selected masking block can be overlaid on a specific subject. This is to protect the privacy of a specific subject included in the captured image of the surveillance camera.

However, in the related art, a user may not set privacy masking for a surveillance camera that cannot be remotely controlled, which may infringe privacy.

Therefore, the present invention was created to solve the above problems, and in the case of a surveillance camera that cannot be remotely controlled, the security camera can set privacy masking through a specific key button provided at the rear of the camera. The purpose is to provide a way to set up privacy masking.

The privacy masking setting method of the surveillance camera according to the present invention for achieving the above object comprises the steps of: superimposing and displaying a masking block set by the user at a specific position on the screen; Storing information about the modified masking block when the masking block of the user is modified through an input unit provided in the surveillance camera; And superimposing and displaying the masking block having the stored information on the surveillance video image.

Hereinafter, a preferred embodiment of a privacy masking setting method in a surveillance camera according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 illustrates a configuration of a general surveillance camera, including a charge coupled device (CCD) 10, an A / D converter 20, a digital signal processor 30, a microcomputer 40, and a memory. 60 is configured to include.

In addition, in order to protect privacy for a specific subject included in the captured image, a masking generator 50 for overlapping and displaying a masking block such as a mosaic image is further included.

On the other hand, the rear end of the surveillance camera of Figure 1 is basically provided with a plurality of key buttons (not shown), in the present invention, it is possible to set the privacy masking using a specific key button specified among the key buttons, This will be described in detail below.

FIG. 2 is a flowchart illustrating a preferred embodiment of a privacy masking setting method for a surveillance camera according to the present invention. Hereinafter, the masking setting method of FIG. 2 according to the present invention will be described with reference to the configuration of FIG. 1. It will be described in detail.

In the surveillance camera having the configuration as shown in FIG. 1, if the microcomputer 40 is designed to interface with an external input device and also to set privacy masking through the external input device, The user can remotely set privacy masking through the external input device.

By the way, if the surveillance camera is not capable of remote control, the user uses a key button that is specified for the 'privacy masking setting' according to the present invention among the key buttons provided at the rear of the surveillance camera. Privacy masking is set as follows.

First, when the predetermined key button is selected and input (S10), the microcomputer 40 enters the 'privacy masking setting mode' (S11) and shows a 1x zoom state (Zoom Status = x1) as shown in FIG. The masking generating unit 50 is controlled to display a virtual masking block (image) superimposed on the A, B, C, D subject in the surveillance video image captured by the microcomputer 40. The position coordinate value of the block (for example, the center of the subject) and the size, the color (for example, Black) / pattern, etc. are specified.

Accordingly, the masking generation unit 50 outputs the screen by placing a virtual masking block having a color / pattern designated by the microcomputer 40 and a size at the center of the A, B, C, and D subjects. .

Therefore, the user can check the position coordinate value and size, color / pattern, etc. of the virtual masking block through the surveillance video image displayed on the screen. From this, the user can select the desired position coordinate value, size, color / By selecting and specifying the pattern, desired privacy masking can be set (S20).

According to the user's privacy masking setting, the microcomputer 40 sets the position coordinate values (start position coordinate values (Xs, Ys) and end position coordinate values (Xe, Ye)), size, and color of the privacy masking. For example, by storing the red / pattern and the like in the memory 60 (S21) and controlling the masking generation unit 50 with reference to the stored values, the user will be described later with reference to FIG. 4. The privacy masking block according to the setting of is superimposed and displayed on the subject A image (S22), and a series of operations are performed to prevent the subject A from being displayed in the surveillance video image.

The user can reset the masking block at any time by using a key button designated for the 'privacy masking setting', and the information on the masking block stored in the memory 60 is updated whenever the masking block is reset by the user.

Meanwhile, in the above embodiment, the virtual masking block may be set by a user, and when the user sets a position coordinate value and a size, a color / pattern, etc. for the virtual masking block, the microcomputer 40 may The set information is stored in the memory 60. In this case, the microcomputer 40 may determine a position coordinate value (for example, a center of a subject) and a size, color (for example, Black) / pattern of the virtual masking block. And the like are based on the information stored in the memory 60.

Further, in the above embodiment, the key button for 'privacy masking setting' and the key button for selecting and specifying the position coordinate value, size, color / pattern, etc. of the privacy masking may be the same key button or different key buttons. In the case of the same key button, the microcomputer 40 recognizes the 'privacy masking setting' upon initial input of the key button, and subsequently selects and designates a position coordinate value, a size, a color / pattern, etc. each time the key button is input. Make sure

Or more, preferred embodiments of the present invention described above, for the purpose of illustration, those skilled in the art, within the technical spirit and the technical scope of the present invention disclosed in the appended claims below, to further improve various other embodiments Changes, substitutions or additions will be possible.

Privacy masking setting method in the surveillance camera according to the present invention as described above, even in the case of a surveillance camera that can not be remotely controlled, the user can set the privacy masking through the key button provided at the rear of the surveillance camera It is a very useful invention that can effectively prevent the exposure display of a specific subject requiring privacy protection.
