Abstract

Abstract In a navigation system (100), a map matching between current position data obtained by measuring a current position of a movable body and map data stored beforehand is carried out, and the current position of the movable body is displayed on a displayed map. The navigation system includes: a first storage device for storing position data indicating positions of facilities, facility type data indicating types of the facilities, and guides marks denoting the facilities; and a second storage device for storing display type data indicating the types of facilities to be displayed on the displayed map. The navigation system further includes a guide mark display control device (5), coupled to the first storage device and the second storage device, for reading the position data related to facilities to be displayed from the first storage device and for displaying the guide marks at positions corresponding to the positions of the facilities to be displayed on the displayed map on the basis of the position data and the guide mark data.

Claims Analysis

Total Claims: 4

Claim 1

Independent Claim 183 words

A navigation system (100) comprising: position measurement means (1,2,3,4) for measuring a current position of a movable body and for generating current position information indicating the current position of the movable body; facility information storage means for storing facility information related to particular facilities contained in said map information; map information storage means for storing map information; input means (11) for externally inputting operation instructions to the navigation system; image display means (13) for displaying information; and control means (5), coupled to said position measurement means, said map information storage means, said facility information storage means, said input means and said image display means, for reading the map information from the map information storage means, making said image display means display the map information, making said image display means display said mark image information serving as marks denoting the particular facilities at positions associated with the map information, and making said image display means display photograph information related to one or a plurality of selected particular facilities corresponding to selected mark image information selected by the operation instruction input from the input means.

Claim 2

Dependent Claim 200 words

A navigation system (100) comprising: position measurement means (1,2,3,4) for measuring a current position of a movable body and for generating current position information indicating the current position of the movable body; facility information storage means for storing facility information related to particular facilities contained in said map information; map information storage means for storing map information; input means (11) for externally inputting operation instructions to the navigation system; image display means (13) for displaying information; means (18) for generating an acoustic output corresponding to said facility information; and control means (5), coupled to said position measurement means, said map information storage means, said facility information storage means, said input means, said image display means and said acoustic output generating means, for reading the map information from the map information storage means, making said image display means display the map information, making said image display means display said mark image information serving as marks denoting the particular facilities at positions associated with the map information, and making said acoustic output generating means output information related to one or a plurality of selected particular facilities corresponding to selected mark image information selected by the operation instruction input from the input means.

Claim 3

Dependent Claim 40 words

A navigation system as claimed in claim 1 or 2, wherein said control means is adapted to make said image display means display character information to explain the content of the particular facilities at positions associated with the map information.

Claim 4

Dependent Claim 42 words

A navigation system as claimed in any one of claims 1 to 3, wherein said position measurement means comprises at least one of a GPS receiver (1), an azimuth sensor (2), an angular speed sensor (3) and a travel distance sensor (4).
