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 having a navigation function, comprising:

a camera;

a display configured to display a picture photographed by the camera;

a first detector configured to detect a present location of the mobile terminal,

a second detector configured to detect a direction of said camera,

an operating section configured to set a destination selected by a user of the mobile terminal,

an access section configured to receive route information from said present location to said destination from a server based on said destination and said present location,

a calculator section configured to calculate a traveling direction based on said route information and said direction of the camera, and

a controller configured to control said display to display an indicator indicating said traveling direction on the picture photographed by the camera, and if said destination is shown in the picture photographed by the camera, the controller is further configured to control said display to display a mark indicating said destination on the picture photographed by the camera at a position corresponding to said destination.

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

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

4. The mobile terminal having the 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 having the navigation function according to claim 3, further comprising:

a third detector configured to detect an angle of the camera to a horizontal plane,

a display adjuster configured to adjust said arrow corresponding to an angle of a ground in the picture photographed by the camera.

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

a third detector configured to detect an angle of the camera to a horizontal plane,

an arrow display angle controller configured to control said arrow corresponding to an angle of a ground in the picture photographed by the camera.

8. The mobile terminal having the navigation function according to claim 1, wherein the mark indicating said destination is displayed on the picture photographed by the camera when said destination is within a predetermined distance from said present location.

2. A mobile terminal having a navigation function comprising:

a camera;

a display configured to display a picture photographed by the camera;

a first detector configured to detect a present location of said mobile terminal,

a second detector configured to detect a direction of the camera,

a memory for storing map data,

an operating section configured to set a destination selected by a user of the mobile terminal,

a first calculator section configured to calculate a route from said present location to said destination based on said destination, said present location and said map data,

a second calculator section configured to calculate a traveling direction based on said route and said direction of the camera, and

a controller configured to control said display to display an indicator indicating said traveling direction on the picture photographed by the camera, and if said destination is shown in the picture photographed by the camera, the controller is further configured to control said display to display a mark indicating said destination on the picture photographed by the camera at a position corresponding to said destination.

9. The mobile terminal having the navigation function according to claim 2, wherein the mark indicating said destination is displayed on the picture photographed by the camera when said destination is within a predetermined distance from said present location.

7. A method for displaying on a display of a mobile terminal travelling directions on a picture photographed by a camera of the mobile device, the method comprising:

a) detecting a present location of the mobile terminal,

b) detecting a direction of said camera,

c) receiving a user selection of a destination,

d) receiving 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 based on said route information and said direction of the camera; and

f) displaying an indicator indicating said traveling direction on the picture photographed by the camera, and if said destination is shown on the picture, displaying a mark indicating said destination on the picture photographed by the camera at a position corresponding to said destination.

10. The control method of a displaying mobile terminal according to claim 7, wherein the displaying includes displaying the mark indicating said destination on the picture photographed by the camera when said destination is within a predetermined distance from said present location.
