First Claim
1. A navigation apparatus, comprising:
- front side image display means for displaying an image of a front side and back side image display means for displaying an image of a back side, the each image being one of images which stereoscopically overlap along a line of sight;
measuring means for measuring a current position of an own vehicle;
map storage means for storing map data which includes information indicating whether or not a feature is an elevated road and data of an image of a road; and
control means for controlling each means, wherein the control means reads the map data of a predetermined area, where the current position of the own vehicle is included, from the map storage means, based on the current position of the own vehicle measured by the measuring means;
wherein the control means determines whether or not the elevated road exists in the predetermined area, based on information indicating whether or not the feature, which is registered as the map data, is the elevated road, and wherein when the control means determines that the elevated road exists in the predetermined area, the control means determines whether or not the current position of the own vehicle is on the elevated road, based on the current position of the own vehicle measured by the measuring means, and wherein when the current position of the own vehicle is not on the elevated road, the control means inserts an image of the elevated road included in the map data into a front side image signal for displaying the image of the front side;
the control means transmits the front side image signal to the front side image display means; and
the front side image display means draws the image of the elevated road so that an image drawn on the back side image display means can be visually percepted, based on the front side image signal.

Abstract
A navigation apparatus which includes a front image display displaying an image of a front side and a back image display displaying an image of a back side, the each image being one of images stereoscopically overlapped along the line of sight; a front image signal; a measuring unit for measuring a current position of own vehicle; a map storage unit; a controller for controlling each unit, wherein the controller reads map data of a predetermined area and determines if an elevated road exists in the area, wherein when the elevated road exists, the controller checks whether or not the current position of the own vehicle is on the elevated road, and wherein when the current position is not on the elevated road, the front image display draws the image of the elevated road so that an image drawn on the back image display can be visually percepted.
