Navigation device and program product for displaying magnified intersection view
First Claim
Patent Images
1. A navigation device for performing, when approaching an intersection on a route to a destination, route guidance by displaying a magnified view of the intersection, comprising:
- a storage medium for storing address range data for links connected to the intersection, in the address range data each of the links being correlated with a house number range including house numbers, the house numbers being given along the each of the links in ascending order;
a controlling circuit for selecting, based on the stored address range data, a facility corresponding to a house number within house number ranges correlated with the links connected to the intersection; and
an image display device for displaying, together with the magnified view of the intersection, a landmark of the facility selected by the control circuit.

Abstract
A navigation device for a vehicle selects, as facilities for displaying with a magnified view of a guidance intersection on a recommended route to a destination, only facilities along an entering road through which the recommended route goes just before entering the guidance intersection and facilities at the corners of the guidance intersection. Then the navigation device displays the magnified view and the selected landmarks together.
