Information processing apparatus and method, and providing medium
First Claim
1. An information processing apparatus for drawing a map image corresponding to digitized map information, comprising:
- route search means for searching an objective route based on an input operation of a user;
road map drawing means for drawing a road map having at least a plurality of roads including a road of said objective route searched by said route search means in a mode differentiated by a road type; and
emphasis line drawing means for drawing emphasis lines to indicate said objective route at both outer sides of said road of said objective route throughout an overall length of said objective route, without hiding said road type.

Abstract
There is provided an information processing apparatus in which when a route to a destination is searched, a road of the route is displayed with emphasis while a color or shape indicating the type of the road can be checked. When the route to the destination is searched, both sides of the road of the searched route are displayed with emphasis lines. The inside of both the sides of the road is displayed such that the type of the road, such as an expressway or an open load, can be recognized. By this, a user can easily check the searched route, and can check the type of the road of the route. For example, in the route from a current location to a destination, the user can check that a route A is an expressway, and other route B, route C, and route D are open roads.
