Abstract

When a vehicle is driving, a camera image can be selected that photographing a front or other direction of a vehicle in real time to display the selected image on a background screen of a menu screen in a navigation device. In addition, selection buttons of the menu screen is displayed to be transparent or translucent. Since a driver can keep eyes a moving direction of the vehicle while manipulating a navigation device, possible accidents of the vehicle can be prevented in advance.

Claims

1. A navigation device comprising:

an interface unit to receive a camera image;

a display unit to display a menu screen; and

a control unit configured to control such that the camera image is displayed on a background screen in the menu screen.

2. The navigation device according to claim 1, wherein the control unit is configured to control such that the camera image is displayed on the background screen in the menu screen when a display of the menu screen is requested or the menu screen of the display unit is touched in a state where a vehicle is driving.

3. The navigation device according to claim 2, wherein the control unit is configured to determine a state where a vehicle is driving, based on a gear state or speed of the vehicle that transmitted through the interface, or a GPS signal or an output of a sensor in the navigation device.

4. The navigation device according to claim 1, wherein the control unit is configured to control such that the camera image corresponding to a driving direction of the vehicle is selected and displayed on the background screen in the menu screen.

5. The navigation device according to claim 4, wherein the control unit is configured to determine the driving direction of the vehicle, based on a gear state or speed of the vehicle that transmitted through the interface, or a GPS signal or an output of a sensor in the navigation device.

6. The navigation device according to claim 1, wherein the control unit is configured to control such that a selection button of the menu screen is displayed to be transparent or translucent when the camera image is displayed on the background screen in the menu screen.

7. The navigation device according to claim 1, wherein the control unit is configured to control such that only a portion in a frame of the camera image is displayed on the background screen in the menu screen.

8. The navigation device according to claim 1, wherein the control unit is configured to control such that the camera image is displayed on a PIP or P&

P screen when the menu screen is displayed on a sub-screen.

9. The navigation device according to claim 1, wherein the camera image is inputted from a camera for a black box that photographs front or other directions of the vehicle in real time.

10. A method for displaying a background screen in a navigation device, comprising:

receiving a camera image photographed in real time, and

displaying the camera image on a background screen of a menu screen when a vehicle is driving.

11. The method according to claim 10, wherein the displaying selects and display a camera image corresponding to a driving direction of the vehicle on the background screen in the menu screen.

12. The method according to claim 11, further comprising:

determining a driving state and/or the driving direction of the vehicle, based on a gear state or speed of the vehicle that transmitted through an interface, or a GPS signal or an output of a sensor in the navigation device.

13. The method according to claim 10, wherein the displaying displays a selection button of the menu screen to be transparent or translucent.

14. The method according to claim 10, wherein the displaying displays only a portion area in a frame of the camera image on the background screen in the menu screen.

15. The method according to claim 10, wherein the displaying displays the camera image on a PIP or P&

P screen when the menu screen is displayed on a sub-screen.
