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

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.

6. An image display method for a navigation apparatus, the apparatus comprising:
-
a front side image display unit for displaying an image of a front side and a back side image display unit for displaying an image of a back side, each image being one of images which stereoscopically overlap along the line of sight; a measuring unit for measuring a current position of an own vehicle; and a map storage unit 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, the image display method comprising; reading the map data of a predetermined area where the current position of the own vehicle is included from the map storage unit, based on the current position of the own vehicle measured by the measuring unit; transmitting the data of an image of a road of the acquired map data to the back side image display unit; determining whether or not an 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 upon determining that that an elevated road exists in the predetermined area determining whether or not the current position of the own vehicle is on the elevated road, and upon determining that the current position of the own vehicle is not on the elevated road transmitting data of an image of the elevated road included in the map data provided to the front side image display unit, and wherein the front side image display unit draws the image of the elevated road so that an image drawn on the back side image display unit can be visually percepted. - View Dependent Claims (7, 8, 9, 10, 11)
