Abstract

A position detector is configured to detect a current position of a moving body. A condition detector is configured to detect moving conditions including a forward direction of the moving body. A display unit is configured to display a predetermined image overlaid on the landscape in front of the moving body. A storage unit is configured to store the position of each intersection in a route along which the moving body moves and the position and shape of each object existing around the intersection. A selector is configured to select any one of the objects existing around an intersection for which guidance is needed when the moving body nears the intersection. A drawing controller is configured to draw on the display unit, a guide figure indicating the object selected by the selector.

Claims

1. A navigation device comprising:

a position detector configured to detect a current position of a moving body;

a condition detector configured to detect moving conditions including a forward direction of the moving body;

a display unit configured to display a predetermined image overlaid on the landscape in front of the moving body;

a storage unit configured to store the position of each intersection in a route along which the moving body moves and the position and shape of each object existing around the intersection;

a selector configured to select any one of the objects existing around an intersection for which guidance is needed when the moving body nears the intersection; and

a drawing controller configured to draw on the display unit, a guide figure indicating the object selected by the selector.

2. The navigation device according to claim 1, wherein based on the current position detected by the position detector, the moving condition detected by the condition detector, and the position and shape stored in the storage unit for the object selected by the selector, the drawing controller draws the guide figure so that the guide figure is seen on the corresponding object in the landscape in front of the vehicle.

3. The navigation device according to claim 1, wherein the selector selects any one of the objects based on priorities determined according to a positional relationship between the moving body and each object around the intersection.

4. The navigation device according to claim 1, wherein the drawing controller draws the guide figure at a display position which is corrected based on a difference in altitude between the current position of the moving body and the position of the intersection for which guidance is needed.

5. A navigation device comprising:

a position detector configured to detect a current position of a moving body;

a display unit configured to display a predetermined image overlaid on the landscape in front of the moving body;

a photographing unit configured to take an image of the landscape in front of the moving body;

a selector configured to select a lane that the moving body is to travel in a route included in the image of the landscape photographed by the photographing unit when the moving body nears an intersection for which guidance is needed; and

a drawing controller configured to draw on the display unit, a guide figure indicating the lane selected by the selector.

6. A display control method, comprising:

detecting a current position of a moving body;

detecting moving conditions including a forward direction of the moving body;

selecting any one of objects existing around an intersection for which guidance is needed when the moving body nears the intersection; and

drawing a guide figure indicating the selected object on a display unit so that the guide figure is overlaid on the landscape in front of the moving body.

7. A display control method, comprising:

detecting a current position of a moving body;

taking an image of the landscape in front of the moving body;

selecting a lane that the moving body is to travel in a route included in the taken image of the landscape when the moving body nears an intersection for which guidance is needed; and

drawing a guide figure indicating the selected lane on a display unit so that the guide figure is overlaid on the landscape in front of the moving body.
