Abstract
Abstract A navigation device which is operative to navigate a user along a predetermined route, utilizing displays of relevant map sections via a display unit, under the control of a control unit which comprises picture processing means which reproduce the predetermined route within the map section in a distinct manner, the segment travelled and the segment yet to be travelled being reproduced in a distinct manner, resulting in a display which can be very quickly interpreted.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
151 words
A navigation device, comprising a memory for the storage of cartographic data, a position sensing unit, a control unit, an input unit, a picture memory and a display unit, the control unit being adapted to navigate a user along a predetermined route on the basis of data from the position sensing unit and the cartographic data, the control unit also being adapted to store repeatedly in the picture memory cartographic data, selected in dependence on a current position determined by the position sensing unit, for display of a relevant map section via the display unit, characterized in that the control unit comprises picture processing means for displaying, via the display unit, the predetermined route in a distinct manner within the map section, the picture processing means representing the route segment travelled to reach said current position and the route segment to be travelled beyond said current position in a different manner.
Claim 2
Dependent Claim
23 words
A navigation device as claimed in Claim 1, characterized in that the picture processing means represent said current position in a flashing manner.
Claim 3
Dependent Claim
52 words
A navigation device as claimed in Claim 1 or 2, characterized in that the picture processing means represent the route in a first distinct colour for the route segment travelled to reach the current position and in a second distinct colour for the route segment to be travelled beyond the current position.
Claim 4
Dependent Claim
48 words
A navigation device as claimed in any one of the Claims 1, 2 or 3, characterized in that the picture processing means represent the direction to be followed in conformity with the predetermined route as an arrow which extends substantially parallel to or is coincident with the route.
Claim 5
Dependent Claim
62 words
A navigation device as claimed in any one of the Claims 1, 2, 3 or 4, characterized in that the picture processing means represent the route as a double line wherebetween a first distinct colour is displayed for the route segment travelled preceding the current position and a second distinct colour for the route segment to be travelled beyond the current position.
Claim 6
Dependent Claim
28 words
A navigation device as claimed in Claim 5, characterized in that the picture processing means represent the double line in the first or in the second distinct colour.
Claim 7
Dependent Claim
64 words
A navigation device as claimed in any one of the Claims 1, 2, 3, 4, 5 or 6, characterized in that the picture processing means are adapted to represent the current position when the latter is not situated along the predetermined route, the picture processing means then representing the segment travelled and the segment not travelled of the predetermined route in a different manner.
Claim 8
Dependent Claim
18 words
A vehicle comprising a navigation device as claimed in Claim 1, 2, 3, 4, 5, 6 or 7.
