Abstract

The present invention provides a mobile terminal with navigation function which is able to display traveling directions on a photographed picture displayed on the display. The mobile terminal with navigation function of the present invention detects the present location of the cellular phone, detects the direction of the camera, sets the destination, receives the route information from present location to the destination from the server based on the destination and present location, calculates the traveling direction on the photographed picture based on the route information and direction of the camera and adds the traveling direction onto the photographed picture displayed on the display.

Claims

1. A mobile terminal with navigation function which has a camera and a display for displaying a photographed picture comprising:

a first detector for detecting a present location of the mobile terminal,

a second detector for detecting a direction of said camera,

a setting part for setting a destination,

a receiving part for receiving a route information from said present location to said destination from a server based on said destination and said present location,

a calculator for calculating a traveling direction on the photographed picture based on said information and said direction of the camera, and

a controller for controlling an indicator indicating said traveling direction displayed on the photographed picture.

3. The mobile terminal with navigation function according to claim 1 or 2,

wherein an arrow is used as said indicator indicating the traveling direction.

4. The mobile terminal with navigation function according to claim 3,

wherein a bending arrow corresponding to a turning direction is used as the arrow indicating the traveling direction if there is a change of the traveling direction within a predetermined distance from the present location.

5. The mobile terminal with navigation function according to claim 3, further comprising

a third detector for detecting an angle of the camera to a horizontal plane,

a display adjuster for adjusting said arrow corresponding to an angle of a ground in the photographed picture.

6. The mobile terminal with navigation function according to claim 4, further comprising

a third detector for detecting an angle of the camera to a horizontal plane,

an arrow display angle controller for controlling said arrow corresponding to an angle of a ground in the photographed picture.

2. A mobile terminal with navigation function which has a display for a photographed picture comprising:

a first detector for detecting a present location of said mobile terminal,

a second detector for detecting a direction of a camera,

a memory for storing map data,

a setting part for setting a destination,

a first calculator for calculating a route from said present location to said destination based on said destination, said present location and said map data,

a second calculator for calculating a traveling direction on the photographed picture based on said route and said direction of the camera, and

a controller for controlling an indicator indicating said traveling direction displayed on the photographed picture.

7. A control method of a displaying mobile terminal with navigation function which has a camera and a display for displaying a photographed picture, the control method comprising:

a) detecting a present location of the mobile terminal,

b) detecting a direction of said camera,

c) setting a destination,

d) receiving a route information from said present location to said destination from a server based on said destination and said present location,

e) calculating a traveling direction on the photographed picture based on said information and said direction of the camera; and

f) displaying an indicator indicating said traveling direction on the photographed picture.
