Similarly, in the vehicle navigation, a map correction menu item may be included and displayed as a user selection menu item on the screen of the GPS data viewing mode for displaying the reception status of the GPS data and the like.

Meanwhile, as illustrated in FIG. 7, the first control unit 170 of the vehicle navigation apparatus 100 includes GPS data, map data, road data, and a sensor. With reference to the data, a map mapping algorithm for correcting an error between the GPS data and the map data may be mounted by software or firmware.

In addition, the map mapping algorithm is a known technique for correcting that the current position of the vehicle navigation is incorrectly displayed on the map due to, for example, a manufacturing error of the map data or a GPS reception error when calculating the current position. As described in detail in Korean Patent Application Publication No. 10-2005-0032406 and Korean Patent Publication No. 10-2008-0101242, etc., a detailed technical description thereof will be omitted.

Meanwhile, in the vehicle navigation apparatus 100, for example, as shown in FIG. 8, the camera image photographed by the camera module 221 of the vehicle black box 200 is displayed in real time, or the vehicle black box. The camera image recorded in the second storage unit 250 of 200 is displayed.

In the vehicle black box 200, video data of a camera image captured by the camera module 221 and GPS data received from the vehicle navigation apparatus 100 may be stored in association with each other. For example, the GPS data may be GPS data in which an error with the map data is corrected by the map mapping algorithm of the vehicle navigation apparatus 100, or GPS data in which the error is not corrected.

On the other hand, the second control unit 270 of the vehicle black box 200, for example, as shown in Figure 9, video encoder 2710, GPS encoder 2711, controller 2712, mux 2713 ), A GPS decoder 2714, a video decoder 2715, and a demux 2716 may be included.

In addition, the video encoder 2710 encodes a camera image photographed by the camera module 221 into video data such as a predetermined format, for example, an MPEG video or a JPEG still image, and the GPS encoder 2711. ), The GPS mapping data of which the error with the map data is corrected, or the GPS data of which the error is not corrected, is converted into a predetermined format, for example, an MPEG video or a JPEG still image, by a map mapping algorithm of the vehicle navigation apparatus 100. It is encoded into a corresponding data packet.

In addition, the controller 2712 performs an interface operation with the first control unit 170 of the vehicle navigation apparatus 100 and generates control data that is management data for video data and GPS data of the camera image. In the mux 2713, the video data, the GPS data, and the control data of the camera image are muxed and stored in a storage 250 such as a hard disk or a nonvolatile memory.

On the other hand, the storage 250, for example, video and GPS link data (Video & GPS Link Information) can be stored in the form of a data file, as shown in Figure 10, the video and GPS link data In the data file of the camera, video data (Video 1,2 ..) and GPS data (GPS 1,2 ..) of the camera image are stored in a 1: 1 connection, and file information is additionally recorded. do,

The file data may include, for example, a file name, a recording date and time, a start position and end position for a specific destination, and an attribute. Various data such as (Attribute) are recorded and recorded.

Meanwhile, the attribute data may include, for example, whether the GPS data is the GPS data whose error is corrected by a map mapping operation (for example, Map Mapping: True = 1), or the GPS data whose error is not corrected (for example, : Map Mapping: False = 0) can be recorded including identification data.

In addition, the controller 2712 may store the video data and the GPS data more efficiently and variously in response to a user's request. For example, as illustrated in FIG. 11, the video of the camera image may be used. Although data is sequentially recorded, the received GPS data is monitored and compared at this time, and when the GS data is changed, only the changed GS data may be stored in association with the video data.

For example, as illustrated in FIG. 12, the controller 2712 records the GS data sequentially, and when the GS data is changed by monitoring and comparing the received GS data, the changed CS data is changed. Only video data of the viewpoint may be stored in association with the GPS data.

In the controller 2712, for example, when performing an output operation of a camera image and a map according to a user's request, the GPS decoder 2714, the video decoder 2715, and the demux 2716 may be used. By controlling the operation, the video data and the GPS data stored in association with the storage 250 is read and decoded.

The decoded video data and GPS data are output to the vehicle navigation apparatus 100, and the vehicle navigation apparatus 100 receives the video data and displays the video data on a screen of the display module 147 as a camera image. In this case, in the first control unit 170 of the vehicle navigation, the GPS data received from the vehicle black box is corrected through the map mapping operation through an interface with the controller 2712 of the vehicle black box. In the case of the GPS data, the map corresponding to the GPS data is displayed on the screen of the display module together with the camera image.

On the other hand, if the GPS data is the GPS data that is not corrected through the map mapping operation, after performing a map mapping operation on the GS data, a map corresponding to the error corrected GPS data is displayed on the screen of the display module. It is displayed along with the camera image.

Accordingly, a camera image and a map are displayed together on the screen of the display module. For example, as shown in FIG. 13, the camera is displayed in a picture in picture (PIP) manner according to a user's request. An image (eg, Sub) and a map (eg, Main) are displayed together, or as shown in FIG. 14. The camera image and the map may be displayed together in a navigation in picture (NIP) method.

In addition, various navigation additional data may be additionally displayed on at least one of the camera image and the map. For example, a name of a specific building or a name of a road located around a road may be added to the map. The recording date and time, and the vehicle speed may be additionally displayed on the camera image.

On the other hand, the map mapping algorithm, as described above, may be mounted in a vehicle navigation, or mounted in a vehicle black box, the data file of the video and GPS link data stored in the storage 250, for example, It may be downloaded and stored through various communication networks such as the Internet and the like.

In addition, the data file of the video and GS link data may be stored in the second storage unit 250 of the vehicle black box or in the first storage unit 150 of the vehicle navigation.

For example, when the driver simulates driving to a specific destination, the driver may simultaneously view a camera image and a map displayed together in the PIP method or the NIP method, and thus move to a specific destination. The route can be identified more easily and accurately.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
