Abstract

An apparatus and method display a world clock on the basis of an Augmented Reality (AR) scheme in a portable terminal. The method for displaying information in the portable terminal includes obtaining camera image data from a camera. The method also include searching for a city corresponding to a camera location and a camera viewpoint direction on the basis of a memory. The method further includes obtaining information on the found city and displaying the obtained information on the found city by compositing the information into the obtained camera image data.

Claims

1. A method of displaying information in a portable terminal, the method comprising:

obtaining camera image data from a camera;

searching for a city corresponding to a camera location and a camera viewpoint direction on the basis of a memory;

obtaining information on the found city; and

displaying the obtained information on the found city by compositing the information into the obtained camera image data.

2. The method of claim 1, wherein the information on the found city comprises at least one of time, a weather, a direction, a distance to a specific city (or country), whether to apply a summer time system, a population, an area, tour information, and a primary landmark.

3. The method of claim 1, further comprising obtaining information on the camera location and the camera viewpoint direction by driving a sensor.

4. The method of claim 3, further comprising determining a composition location of the obtained city information included in the obtained camera image data on the basis of information regarding a location of the found city and stored in the memory and the information on the obtained camera location and camera viewpoint direction.

5. The method of claim 3, wherein searching for the city comprises searching for a city which exists in a current camera location and camera viewpoint direction by using information regarding a location for each city of the world and stored in the memory and the obtained information on the camera location and camera viewpoint direction.

6. The method of claim 3, wherein the sensor includes at least one of a Global Positioning System (GPS) receiver, a gyro sensor, a geomagnetic sensor, and a gravity sensor.

7. The method of claim 1, wherein obtaining the information on the found city comprises:

requesting a web-based server to send information on the found city; and

receiving the information on the found city from the web-based server.

18. The method of claim 1, further comprising:

receiving, at an input unit, key input data when a user manipulates one or more keys.

19. The method of claim 1, further comprising:

generating screen data for displaying the camera image data.

20. The method of claim 18, where the input unit comprises a plurality of function keys.

8. A portable terminal comprising:

a camera configured to obtain camera image data;

a controller configured to search for a city corresponding to a camera location and a camera viewpoint direction on the basis of a memory, obtain information on the found city, and composite the obtained information on the found city into the obtained camera image data; and

a display unit configured to display the city information being composited to the camera image data.

9. The portable terminal of claim 8, wherein the information on the found city comprises at least one of time, a weather, a direction, a distance to a specific city (or country), whether to apply a summer time system, a population, an area, tour information, and a primary landmark.

10. The portable terminal of claim 8, further comprising a sensor configured to obtain information on the camera location and the camera viewpoint direction.

11. The portable terminal of claim 10, wherein the controller determines a composition location of the obtained city information included in the obtained camera image data on the basis of information regarding a location of the found city and stored in the memory and the information on the obtained camera location and camera viewpoint direction.

12. The portable terminal of claim 10, further comprising a memory for storing information on a location for each city of the world, wherein the controller searches for a city which exists in a current camera location and camera viewpoint direction by using the information on the location for each city of the world and the obtained information on the camera location and camera viewpoint direction.

13. The portable terminal of claim 10, wherein the sensor includes at least one of a Global Positioning System (GPS) receiver, a gyro sensor, a geomagnetic sensor, and a gravity sensor.

14. The portable terminal of claim 8, further comprising a communication unit configured to request a web-based server to send information on the found city and receive the information on the found city from the web-based server.

15. The portable terminal of claim 8, further comprising an input unit configured to receive key input data when a user manipulates one or more keys.

16. The portable terminal of claim 8, further comprising an image processor configured to generate screen data for displaying the camera image data.

17. The portable terminal of claim 15, where the input unit comprises a plurality of function keys.
