Abstract
A navigation device displays, on a screen, a route guidance object indicating a route along which the vehicle is to travel, and includes: an image pickup section that obtains a photographed image ahead of the vehicle; a white line detection section that detects a road white line in the photographed image; a map information storage section that stores map information including road shape data which represents the road shape; a road shape data correction section that corrects the road shape data, based on a detection result of the road white line, such that the route guidance object is displayed along the road white line; a route guidance object generation section that generates the route guidance object, based on the corrected road shape data; and the display section that displays the generated route guidance object on the screen.
