The first control unit 170 of FIG. 3 of the vehicle navigation apparatus 100 (100 of FIG. 3) acquires trajectory information corresponding to the image data by using the first position information mapped to the image data selected by the user (S510). That is, the vehicle movement trajectory corresponding to the image data may be acquired through the plurality of first position information mapped to the image data. The locus information may include a plurality of first location information. The plurality of first location information included in the locus information may be arranged over time. Thereafter, the first control unit 170 of FIG. 3 of the vehicle navigation apparatus 100 of FIG. 3 outputs the vehicle movement trajectory based on the trajectory information to the display unit 145 of FIG. 1 (S520).

As illustrated in FIG. 10, the image data selected by the user may be output on the image screen VS, and the vehicle movement trace ML based on the locus information may be output on the map. In this case, the vehicle movement trajectory already passed and the vehicle movement trajectory to be forwarded may be displayed separately. For example, the color, size, type, etc. of the vehicle movement trajectory ML are displayed differently. The vehicle position VP corresponding to the image output on the image screen VS may be output on the vehicle movement trajectory ML. In addition, a progress bar PB indicating a current playback point CP, a file name currently being played, etc., of the total playback time of the video data output on the video screen VS is displayed on the display unit (see FIG. 1). 145). If the operation is not performed by the user for a predetermined time, the progress bar PB output on the display unit 145 of FIG. 1 may disappear. Thereafter, when an operation is performed by the user, the progress bar PB may be output again to the display unit 145 of FIG. 1.

Referring back to FIG. 9, a specific point is selected from the vehicle movement trajectory output to the display unit 145 of FIG. 1 through the input unit 120 of FIG. 3 of the vehicle navigation apparatus 100 of FIG. 3 (S530). . As illustrated in FIG. 11, the user may touch a specific point TP of the vehicle movement trace ML output on the display unit 145 of FIG. 1 on the touch screen by using the finger FG. Meanwhile, the user may point to a specific point TP using a direction key provided in the vehicle navigation apparatus 100 (FIG. 3) or a remote controller connected to the vehicle navigation apparatus 100 (FIG. 3).

Referring back to FIG. 9, the first control unit 170 of FIG. 3 of the vehicle navigation apparatus 100 obtains second location information corresponding to the point TP selected by the user from the map data in operation S540. . In addition to the map information, the map data stores location information for each location in the map. Accordingly, second location information corresponding to the point TP selected by the user may be acquired. Of course, the trajectory information includes first position information, and the point TP selected by the user is located on the vehicle movement trajectory ML based on the trajectory information, and thus corresponds to the point TP selected by the user in the trajectory information. The second location information may be obtained.

The first control unit 170 of FIG. 3 of the vehicle navigation apparatus 100 (100 of FIG. 3) obtains place information from the map data using the second location information (S550). The map data also stores place information and corresponding location information. Accordingly, place information corresponding to the second location information may be obtained. The place information includes address information, place name information, business name information, point of interest (POI) information, and the like. Address information is an identification symbol given by a national or public agency to identify a place. The address information may be a full address, such as "31, 1-ga, Taepyeong-ro, Jung-gu, Seoul," or may be part of a full address, such as "1, Taepyeong-ro, 1-ga, Jung-gu, Seoul," "Yeoksam-dong", "Yeoksam-dong, Gangnam-gu," . The place name information is a name for identifying a village, a province, a mountain stream, an area, and the like, such as "Seorae Village". Trade name is a name used by merchants to identify themselves in business activities such as Lotteria, Starbucks, etc. POI information is a well-known place such as "Gwanghwamun Square", "City Hall Square", or "Gangnam Station", " The name of a subway station such as "Sadang Station", or a national institution or public institution such as "Seoul City Hall", "Jongno-gu Office", etc. Of course, designating a specific place such as "home", "company", etc. by the user as POI. It is possible.

Thereafter, the first control unit 170 of FIG. 3 of the vehicle navigation apparatus 100 of FIG. 3 outputs place information to the display unit 145 of FIG. 1 (S560). As shown in FIG. 12, location information may be output to the additional information output area PI of the video screen VS to which the video data is output. In this case, an image frame corresponding to the point TP selected by the user may be output to the image screen VS. In addition, the vehicle position VP may be updated to a position corresponding to the image frame output on the image screen VS (that is, the point TP selected by the user). Accordingly, the progress bar PB may also be updated. Meanwhile, although the additional information output area PI is illustrated as being positioned at the lower left of the image screen VS, the present invention is not limited thereto, and the location of the additional information output area PI may be changed. Of course, the additional information output area PI may be output to a part other than the image screen VS.

As such, by outputting trajectory information corresponding to the image data, the user may also check the vehicle movement trajectory while viewing the image data. In addition, by outputting the place information on the point selected by the user among the trajectory information, the user can easily confirm the place information on the specific point. In addition, the storage capacity can be reduced by mapping the position information to the image data instead of the place information. As a result, the storage space can be used more efficiently.

Meanwhile, the trajectory information output screen shown in FIG. 10, the point selection screen shown in FIG. 11, and the place information output screen shown in FIG. 12 are just examples and may be configured in other forms.
