Abstract

A method of changing a display mode in a car navigation system, the method including: acquiring distance information from a current vehicle location to a guide point; and gradually changing the display mode into any one of a two-dimensional display mode and a three-dimensional display mode based on the distance information.

Claims

1. A method of changing a display mode in a car navigation system, the method comprising:

acquiring distance information from a current vehicle location to a guide point; and

gradually changing the display mode into any one of a two-dimensional display mode and a three-dimensional display mode based on the distance information.

2. The method of claim 1, wherein the changing comprises:

calculating a vertical angle and a map magnification for changing the current display mode into the two-dimensional display mode when the current display mode is the three-dimensional display mode; and

gradually changing the current display mode into the two-dimensional display mode based on the vertical angle and the map magnification.

3. The method of claim 1, wherein the changing comprises:

calculating a vertical angle and a map magnification for changing the current display mode into the three-dimensional display mode when the current display mode is the two-dimensional display mode; and

gradually changing the current display mode into the three-dimensional display mode based on the calculated vertical angle and the map magnification.

4. The method of claim 1, wherein the changing comprises:

calculating a vertical angle and a map magnification for changing the display mode into the two-dimensional display mode based on a distance and a time when starting a guide when the current display mode is the three-dimensional display mode; and

gradually changing the three-dimensional display mode into the two-dimensional display mode by applying the vertical angle and the map magnification to a display engine.

6. The method of claim 1, wherein the changing comprises:

determining whether a vehicle is located within a predetermined distance of the guide point based on the distance information; and

gradually changing the display mode into any one of the two-dimensional display mode and the three-dimensional display mode based on a result of the determination.

7. The method of claim 6, wherein the changing of the display mode into any one of the two-dimensional display mode and the three-dimensional display mode based on a result of the determination comprises:

gradually changing the three-dimensional display mode into the two-dimensional display mode when the vehicle is located within the predetermined distance of the guide point; and

gradually changing the two-dimensional display mode into the three-dimensional display mode when the vehicle is located outside the predetermined distance of the guide point.

10. A computer-readable recording medium storing a program for implementing the method according to claim 6

5. (canceled)

8-9. -9. (canceled)

11. An apparatus for changing a display mode in a car navigation system, the apparatus comprising:

a distance information acquisition unit to acquire distance information from a current vehicle location to a guide point;

a determination unit to determine whether a vehicle is located within a predetermined distance of the guide point based on the distance information, and determine whether a current display mode of the vehicle is any one of a two-dimensional display mode and a three-dimensional display mode; and

a display mode change unit to gradually change the display mode into any one of the two-dimensional display mode and the three-dimensional display mode based on a result of the determination.

12. The apparatus of claim 11, wherein the display mode change unit comprises:

a calculation unit to gradually change the three-dimensional display mode into the two-dimensional display mode when the vehicle is located within the predetermined distance of the guide point; and

a mode change unit to gradually change the two-dimensional display mode into the three-dimensional display mode when the vehicle is located outside the predetermined distance of the guide point.

13. The apparatus of claim 11, wherein the display mode change unit comprises:

a calculation unit to calculate a vertical angle and a map magnification for changing the current display mode into the two-dimensional display mode when the current display mode is the three-dimensional display mode; and

a mode change unit to gradually change the current display mode into the two-dimensional display mode based on the vertical angle and the map magnification.

14. The apparatus of claim 11, wherein the display mode change unit comprises:

a calculation unit to calculate a vertical angle and a map magnification for changing the current display mode into the three-dimensional display mode when the current display mode is the two-dimensional display mode; and

a mode change unit to gradually change the two-dimensional display mode into the three-dimensional display mode based on the calculated vertical angle and the map magnification.

15. The apparatus of claim 11, wherein the display mode change unit comprises:

a calculation unit to calculate a vertical angle and a map magnification for changing the display mode into the two-dimensional display mode based on a distance and a time when starting a guide when the current display mode is the three-dimensional display mode; and

a mode change unit to gradually change the three-dimensional display mode into the two-dimensional display mode by applying the vertical angle and the map magnification to a display engine.

16. The apparatus of claim 11, wherein the display mode change unit comprises:

a calculation unit to calculate a vertical angle and a map magnification for changing the display mode into the three-dimensional display mode based on a distance and a time when completing a guide when the current display mode is the two-dimensional display mode; and

a mode change unit to gradually change the current display mode into the three-dimensional display mode by applying the vertical angle and the map magnification to a display engine.

17. The apparatus of claim 11, wherein the two-dimensional display mode changes a view angle of the guide point in a change section from a point in time of starting a conversion, which is convertible from the three-dimensional display mode into the two-dimensional display mode, to a point in time of completing the conversion from the three-dimensional display mode into the two-dimensional display mode.

18. The apparatus of claim 17, wherein the two-dimensional display mode changes the view angle of the guide point according to any one of a map magnification and a display area based on the distance information.
