The storage unit 110 stores information on a photographing time and photographing location at which an image is captured in response to the image photographed by the vehicle, and the communication unit 120 communicates with a central server collecting images through a communication network. In this case, the central server may be a server used by government agencies such as the National Police Agency and the National Intelligence Service dealing with incident records. In addition, a mobile communication network may be used as the communication network used for communication with the central server, or a separate network may be used. The photographing time and photographing position information stored in correspondence with the photographed image may be inputted together with the image from the photographing means of the image, and may store time information and GPS location information measured by itself when the received image is stored.

When the image search unit 130 receives a request message including the search time and the search location information from the central server through the communication unit 120, the image search time of the image stored in the storage unit 110 matches the search time and the search location. And search the stored selected image corresponding to the shooting position.

The request message transmitted from the central server may be transmitted in the form of an incident list including time, place and event information selected from the incident database provided in the central server. In addition, the request message may be transmitted in response to the query message transmitted from the image search unit 130 to the central server through the communication unit 120.

That is, the image retrieval unit 130 transmits a query message about whether to transmit the image, and when a request message including time and location information of the image to be collected is received from the central server, the image retrieval unit 130 receives the corresponding time and The selected image matching the location information is searched. The query message may be transmitted to the central server at a predetermined time interval, for example, at a predetermined time of day or whenever the vehicle is turned on.

In addition, the image retrieval unit 130 may search for the selected image among images that have not been transmitted to the central server in the past and exclude the image that has already been transmitted to the central server in the past. To this end, the transmission record is stored together with the image transmitted to the central server among the images stored in the storage 110, and the image search unit 130 searches for the selected image among the images in which the transmission record is not stored. By doing so, only some selected images, not all images stored in the black box, are transmitted to the central server, thereby minimizing the amount of data transmission occurring in the communication network.

The selected image retrieved by the image retrieval unit 130 is not immediately transmitted to the central server and undergoes a process of receiving user approval. This is to prevent invasion of personal information, and a user who determines whether to transmit a selection image may be a driver of a vehicle in which a vehicle black box is installed.
