Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A navigation device for displaying a current position and a digital map based on map data made up of electronic information, the device comprising: registration means for registering an index of spot information designated by an operation of a user, in which each spot information has a map coordinate associated therewith; and display means for displaying as a list a plurality of indexes registered by the registration means, wherein the display means displays, together with the list, a digital map using the map coordinate corresponding to an index selected from the plurality of indexes.
Claim 2
Dependent Claim
94 words
A navigation device for displaying a current position and a digital map based on map data made up of electronic information, the device comprising: registration means for registering an index of spot information designated by an operation of a user, in which each spot information has a map coordinate associated therewith; and display means for displaying as a list a plurality of indexes registered by the registration means, wherein the display means displays, together with the list, a digital map using the map coordinate corresponding to an index selected from the plurality of indexes.
Claim 3
Dependent Claim
35 words
The navigation device as claimed in claim 1 , further comprising extraction means for extracting the digital map of the selected index fed to the display means from stored map data using the map coordinate.
Claim 4
Dependent Claim
28 words
The navigation device as claimed in claim 1 , wherein the display means displays additional information about a vicinity of the spot information together with the digital map.
Claim 5
Dependent Claim
24 words
The navigation device as claimed in claim 3 , wherein the additional information is information acquired from outside the navigation device via a network.
Claim 6
Dependent Claim
98 words
A digital map display system for displaying a digital map based on map data made up of electronic information, the system comprising: registration means for registering an index of a predetermined spot in the digital map in accordance with an operation of a user; and display means for displaying a plurality of indexes registered by the registration means in response to a request from the user, wherein the display means displays an image associated with a predetermined index selected by the user from the plurality of indexes, together with the plurality of indexes displayed by the display means.
Claim 7
Dependent Claim
98 words
A digital map display system for displaying a digital map based on map data made up of electronic information, the system comprising: registration means for registering an index of a predetermined spot in the digital map in accordance with an operation of a user; and display means for displaying a plurality of indexes registered by the registration means in response to a request from the user, wherein the display means displays an image associated with a predetermined index selected by the user from the plurality of indexes, together with the plurality of indexes displayed by the display means.
Claim 8
Dependent Claim
51 words
The digital map display system as claimed in claim 5 , wherein the registration means registers data of the spot coordinate of a predetermined spot together with the plurality of indexes, and the display means displays a digital map extracted from the map data on the basis of the spot coordinate.
Claim 9
Dependent Claim
134 words
A digital map displaying method in a navigation device for displaying a current position and a digital map based on map data made up of electronic information, the method comprising: a step of registering in a database an index of spot information designated by an operation of a user, in which each spot information has a map coordinate associated therewith; a step of displaying a plurality of indexes as a list; a step of reading, from the database, data of a map coordinate associated with an index selected from the list; a step of extracting map data corresponding to the data of the map coordinate read in the step of reading; and a step of displaying a digital map based on the map data extracted in the step of extracting together with the list.
Claim 10
Dependent Claim
134 words
A digital map displaying method in a navigation device for displaying a current position and a digital map based on map data made up of electronic information, the method comprising: a step of registering in a database an index of spot information designated by an operation of a user, in which each spot information has a map coordinate associated therewith; a step of displaying a plurality of indexes as a list; a step of reading, from the database, data of a map coordinate associated with an index selected from the list; a step of extracting map data corresponding to the data of the map coordinate read in the step of reading; and a step of displaying a digital map based on the map data extracted in the step of extracting together with the list.
Claim 11
Dependent Claim
49 words
The digital map displaying method in a navigation device as claimed in claim 7 , wherein the step of displaying the digital map includes setting a display of the digital map together with the list so that the spot information is substantially at a center of the digital map.
Claim 12
Dependent Claim
120 words
A program for use in a navigation device, wherein the program causes the navigation device to execute: a function to register in a database an index of spot information designated by an operation of a user in which each spot information has a map coordinate associated therewith; a function to display a plurality of indexes as a list; a function to read, from the database, data of a map coordinate associated with an index selected from the list; a function to extract map data corresponding to the data of the map coordinate read by the function to read; and a function to display a digital map based on map data extracted by the function to extract together with the list.
Claim 13
Dependent Claim
120 words
A program for use in a navigation device, wherein the program causes the navigation device to execute: a function to register in a database an index of spot information designated by an operation of a user in which each spot information has a map coordinate associated therewith; a function to display a plurality of indexes as a list; a function to read, from the database, data of a map coordinate associated with an index selected from the list; a function to extract map data corresponding to the data of the map coordinate read by the function to read; and a function to display a digital map based on map data extracted by the function to extract together with the list.
