Method of displaying navigation data for a vehicle in an image of the vehicle environment, a navigation system for performing the method, and a vehicle comprising a navigation system
First Claim
1. A method of displaying navigation data for travel of a sterrable vehicle through a network of intersecting roads, comprising generating a generally forward looking image of a local vehicle environment by an image pick-up unit, displaying said image on a display unit, and superimposing on said displayed image, at a position in said displayed image proximate an upcoming intersection between a road of current travel and an intersecting road, an indication signal formed from the navigation data indicating a direction of travel to be taken at said intersection of roads.

Abstract
A method of and system for displaying navigation data for a vehicle in conjunction with an image of the vehicle environment, in which from navigation data of a vehicle, derived from a navigation system, there is formed an indication signal which is superposed on an image of the local environment generated by an image pick-up unit. The combination of indication signal and local environmental image is displayed on a display unit.

7. A vehicular navigation display system for displaying navigation data generated by a navigation system in conjunction with an image of a local vehicle environment, comprising:
- an image pick-up means for generating an image of the local environment, a transformation means for transforming said navigation data in conformity with a position of the image pick-up means with respect to the environment, a video generator means for generating an indication signal from the transformed navigation data for marking a path to be followed with respect to the environment, a combination means for combining the image of the environment and the indication signal so as to form a combined image signal representing said indication signal superimposed on the image of the environment, and a display unit for displaying the combined image signal.

9. A method of displaying navigational data for a steerable vehicle in conjunction with an image of a local vehicle environment, comprising:
- generating an image of the local environment from a point of view of an image pick-up unit carried by the vehicle, transforming said navigation data in conformity with a position of the image pick-up unit with respect to the environment, generating an indication signal from the transformed navigation data for marking a path to be followed with respect to the environment, combining the image of the environment and the indication signal so as to form a combined image signal representing said indication signal superimposed on the image of the environment, and displaying the combined image signal on a display unit.
