The bearing information is received from the digital compass 240.

The GPS position information and the orientation information transmitted as described above are analyzed through the street view application 252 to obtain and combine the azimuth angle of the position coordinate of the terminal 200 and the selected camera view. The combined position coordinates / azimuth angles are transmitted through the communication unit 210 and transmitted to the map server 300.

Here, the map server 300 searches for a street view corresponding to the corresponding coordinate / azimuth angle using the transmitted coordinate / azimuth angle as a search condition, and transmits the retrieved street view to the terminal 200.

On the other hand, the application execution unit 250, so that the image taken by the camera 230, that is, the camera view is displayed on the display unit 260. Also, the street view transmitted from the map server 300 is displayed on the display unit 260.

Here, before selecting the selected camera view, the display unit 260 may be displayed in full screen.

Meanwhile, when the selected camera view is selected, the selected camera view and the street view may be displayed on the display unit 260. For example, as the default screen, both the selected camera view and the street view may be displayed in different areas of the display unit 260. Here, when the user touches a region where the selected camera view is displayed twice in a specific operation, for example, a touch phone, the selected camera view may be displayed in full screen. In this case, when the selected camera view displayed on the full screen is touched twice, both the selected camera view and the street view may be displayed again. Such a screen display method can be similarly applied to the display of the street view.

Of course, the above screen display method as an example, it is apparent to those skilled in the art that various methods can be applied in addition.

In addition, the application execution unit 250 may further display the position coordinates / azimuth angle information on the display unit 260. The application execution unit 250 may further display information related to the transmission state of the street view on the display unit 260. Of course, the application execution unit 250 may further display various other information related to the street view display on the display unit 250.
