Abstract
Abstract In a map information display device, the map data extracting unit extracts character data corresponding to characters from map data corresponding to the map, and the map data converting unit converts the map data including no character data to a bird's-eye-view map data. The character data converting unit selects designated character data from the extracted character data and converts the character data other than the designated character data to bird's-eye-view character data. Then, the combining unit combines the bird's-eye-view character data, the bird's-eye-view map data and the designated character data to produce combined bird's-eye-view data. Then, the display unit displays the map of bird's-eye-view using the combined bird's-eye-view data.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
158 words
An information display device for use in a navigation apparatus to display a map, having map data including character data and route data, to assist travel of a moving object, said device comprising: data extracting means for extracting character data from the map data; map data converting means for converting the map data, excluding character data, to bird's-eye-view data; character data converting means for selecting designated character data from the extracted character data and for converting non-designated extracted character data to bird's-eye-view character data; combining means for combining the bird's-eye-view character data, the bird's-eye-view map data and the designated character data to produce combined bird's-eye-view data corresponding to at least part of the map; and display means for displaying the at least part of the map using the combined bird's-eye-view data, wherein said designated character data is independent of the route data and corresponds to a character string designated by a user and stored in memory in advance.
Claim 2
Dependent Claim
158 words
An information display device for use in a navigation apparatus to display a map, having map data including character data and route data, to assist travel of a moving object, said device comprising: data extracting means for extracting character data from the map data; map data converting means for converting the map data, excluding character data, to bird's-eye-view data; character data converting means for selecting designated character data from the extracted character data and for converting non-designated extracted character data to bird's-eye-view character data; combining means for combining the bird's-eye-view character data, the bird's-eye-view map data and the designated character data to produce combined bird's-eye-view data corresponding to at least part of the map; and display means for displaying the at least part of the map using the combined bird's-eye-view data, wherein said designated character data is independent of the route data and corresponds to a character string designated by a user and stored in memory in advance.
Claim 3
Dependent Claim
26 words
An information display device according to claim 1 , wherein said designated character data is designated in accordance with a current time of said moving object.
Claim 4
Dependent Claim
31 words
An information display device according to claim 1 , wherein said designated character data is designated in accordance with an area represented on the map where said moving object is travelling.
Claim 5
Dependent Claim
25 words
An information display device according to claim 1 , wherein said designated character data is designated in accordance with a distance from said moving object.
Claim 6
Dependent Claim
