1 is a block diagram illustrating a configuration of a video backup apparatus according to an embodiment of the present invention.

1, the image backup apparatus 200 includes a time setting unit 210, an event setting unit 220, an image analysis unit 230, A voice analysis unit 240, a probability calculation unit 250, an image conversion unit 260, a storage device 270, and a control unit 280. [

The image storage devices 100-1, ..., 100-N store images taken from a camera such as a digital video recorder or a network digital video recorder.

When the video storage devices 100-1 to 100-N are digital video recorders, 16 cameras (Cameras 1 to 16) can be connected and connected. Each of the 16 cameras has a unique channel, For example, the first to the sixteenth channel numbers (CH 1 to 16) may be assigned. In the digital video recorder, surveillance images photographed from the above sixteen cameras are divided and displayed on a monitor screen or recorded for each channel. When the video storage devices 100-1 to 100-N are network digital video recorders, it is possible to receive, record, or monitor an image received from at least one IP camera through the Internet protocol.

The image backup apparatus 200 receives image data from the image storage apparatuses 100-1 to 100-N and performs image and voice analysis according to the time and event set by the user, And backs up the smaller video and audio data among the calculated probabilities.

The time setting unit 210 sets a time for when to backup images received from the video storage devices 100-1 to 100-N under the control of the control unit 280. [ Here, the time setting can be set by the user's choice, for example, from 12:00 am to 4:00 am.

The event setting unit 220 sets an event generation condition for which image is to be backed up to the image received from the image storage apparatuses 100-1 to 100-N under the control of the control unit 280. [ Here, the event occurrence condition is a condition in which an occurrence of an object or an abnormal voice is generated, a user generates a specific image (for example, a face in which face recognition is impossible), a user generates a specific voice , When the color of the screen changes, when a motion occurs in the set area, and the like.

The image analysis unit 230 analyzes the image received from the image storage apparatuses 100-1 through 100-N for a predetermined time under the control of the control unit 280, . In this case, the image analysis is performed by analyzing images such as disappearance of an object in the screen, appearance of an object similar to a specific image inputted by a user, motion detection of an object, image off, etc., .

The voice analysis unit 240 performs voice analysis from the video or voice received from the video storage devices 100-1 to 100-N for a predetermined time under the control of the control unit 280 to generate an event. Here, the voice analysis generates an event through a voice analysis such as a voice having a voice size equal to or higher than a threshold value specified by the user, or a voice specific to the user.

The probability calculating unit 250 calculates a probability for an event occurring at intervals of a predetermined period under the control of the control unit 280. [ Here, the predetermined period is a period for calculating the probability, for example, a period such as the same time for a specific time or a week.

The control unit 280 finally selects an image to be backed up to the storage device 270 with reference to the probability calculation result received from the probability calculation unit 250. [ The control unit 280 controls to back up the event video / audio having a smaller probability to the storage device 270 from the plurality of probability calculation results received from the probability calculation unit 250. [ The more probable event may be a result of a normal video / audio analysis, so that the less likely event video / audio is backed up in the storage device 270.

The event image / voice having a smaller probability of being backed up to the storage device 270 is converted into a predetermined format by the image conversion unit 260 and then backed up to the storage device 270.

In this way, by setting the conditions such as the backup time and the event to be backed up during the image backup, the image corresponding to the corresponding condition is backed up, and furthermore, the probability for the image in which the event occurs is calculated, It is possible to prevent irrelevant image backup of the backup storage device and to detect and monitor important image information quickly and accurately at the time of checking the backed up image.

2 is a flowchart illustrating an operation of an image backup method according to an exemplary embodiment of the present invention.

Referring to FIG. 2, the image backup apparatus 200 sets a time for when to backup images received from the image storage apparatuses 100-1 to 100-N, (Step S100). Here, the time setting can be set by the user's choice, for example, from 12:00 am to 4:00 am. In addition, the event occurrence condition may be an event occurrence condition such as an appearance of an object or an abnormal voice, a user's specific image (for example, a face in which a face can not be recognized), a user's specific voice (e.g., screaming sound) Format.

After the event generation condition and backup time setting for the video / audio are completed, the video backup apparatus 200 performs video / audio analysis on the video / audio received from the video storage devices 100-1 to 100-N And generating an event when the event generation condition set by the user is satisfied (S200). In this case, the image analysis is performed by analyzing images such as disappearance of an object in the screen, appearance of an object similar to a specific image inputted by a user, motion detection of an object, image off, etc., . Here, the voice analysis generates an event through a voice analysis such as a voice having a voice size equal to or higher than a threshold value specified by the user, or a voice specific to the user.

When the event occurs, the image backup apparatus 200 performs a step S300 of calculating a probability for an event occurring every predetermined period of time. Here, the predetermined period is a period for calculating the probability, for example, a period such as the same time for a specific time or a week.

Upon completion of the probability calculation, the image backup apparatus 200 finally selects an image to be stored in the storage device with reference to the probability calculation result, and from the plurality of received probability calculation results, the event image / (S400). ≪ / RTI > Here, since a probability event may be a result of a normal video / audio analysis, the event video / audio having a lower probability is backed up to the storage device.

Meanwhile, the present invention can be embodied in computer readable code on a computer readable recording medium. A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage device and the like, and also a carrier wave (for example, transmission via the Internet) . In addition, the computer-readable recording medium may be distributed over network-connected computer systems so that computer readable codes can be stored and executed in a distributed manner. In addition, functional programs, codes, and code segments for implementing the present invention can be easily deduced by programmers skilled in the art to which the present invention belongs.

The present invention has been described above with reference to preferred embodiments. It will be understood by those skilled in the art that the present invention may be embodied in various other forms without departing from the spirit or essential characteristics thereof. Therefore, the above-described embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is indicated by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
