Image processing system and navigaton system for correlating position data with image data

A navigation system has a processing unit (D) for generating route data relating to a traveled vehicle route, from position data acquired by position acquiring unit (L). The system includes an image data acquiring section (E) for acquiring image data, a first storage section (HD) for storing the acquired image data according to groups of respective destinations and a second storage section (HD) for storing the route data generated by the processing unit (D). A link data generating section (215) correlates the respective destinations with the respective route data via link data. An outputting unit (216) extracts a group linked to a destination by the link data in response to a manual designation of a route data stored in the second storage section (HD) or to a manual or automatic designation of a destination included in that route data and then to output the image data included in that group from the first storage section (HD) to an outputting section.
