Abstract

A method and a terminal for providing a route in a navigation system using a satellite image are provided. The terminal includes a route calculation unit for calculating a route from a current location to a destination when a user inputs the destination, a satellite image requesting unit for requesting a satellite image server for satellite images corresponding to locations on the route and for downloading the requested satellite images, a satellite image storage unit for storing the downloaded satellite images, and a controller for retrieving a satellite image corresponding to the current location from the satellite image storage unit and for displaying the retrieved satellite image simultaneously while downloading the satellite images corresponding to the locations on the route.

Claims

1. A terminal for providing a route in a navigation system using a satellite image, the terminal comprising:

a route calculation unit for calculating the route from a current location to a destination when a user inputs the destination;

a satellite image requesting unit for requesting a satellite image server for satellite images corresponding to locations on the route and for downloading the requested satellite images;

a satellite image storage unit for storing the downloaded satellite images; and

a controller for retrieving a satellite image corresponding to the current location from the satellite image storage unit and for displaying the retrieved satellite image simultaneously while downloading the satellite images corresponding to the locations on the route.

2. The terminal as claimed in claim 1, wherein the controller displays the satellite image together with a digital map for the navigation by means of a split screen.

3. The terminal as claimed in claim 1, wherein the controller displays the retrieved satellite image and zooms in/out according to a user input.

4. The terminal as claimed in claim 1, wherein the satellite image requesting unit first downloads a satellite image corresponding to the current location and then downloads satellite images corresponding to next locations on the route.

5. The terminal as claimed in claim 4, wherein while the satellite image requesting unit downloads satellite images and the satellite image storage unit stores the satellite images, the controller retrieves and displays an already stored satellite image corresponding to the current location.

6. A method for providing a route in a navigation system using a satellite image, the method comprising:

calculating a route from a current location to a destination when a user inputs the destination;

requesting a satellite image server for satellite images corresponding to locations on the route;

downloading the satellite images;

storing the downloaded satellite images;

retrieving a satellite image corresponding to the current location from a satellite image storage unit; and

displaying the retrieved satellite image while simultaneously downloading the satellite images corresponding to the locations on the route.

7. The method as claimed in claim 6, further comprising displaying the retrieved satellite image together with a digital map for navigation by means of a split screen.

8. The method as claimed in claim 6, wherein the displaying of the retrieved satellite image comprises displaying the retrieved satellite image and zooming in/out according to a user input.

9. The method as claimed in claim 6, wherein the downloading of the satellite images comprises:

downloading a satellite image corresponding to the current location; and

continuing to download satellite images corresponding to next locations on the route.

10. The method as claimed in claim 9, wherein while the satellite images are downloaded, an already stored satellite image corresponding to the current location is retrieved and displayed for navigation.
