<P>PROBLEM TO BE SOLVED: To solve a problem in which it is difficult to grasp an accurate position since neither perspective nor a distance can visually be grasped with a conventional map type road display panel because of plane map representation by two-dimensional drawing and a map shape (road shape) is distorted and then greatly different from an actual shape on a map type road display panel having a map drawing using perspective to visually grasp the perspective. <P>SOLUTION: Disclosed is the map type road display panel which includes a road map, maintaining an accurate scale shape, displayed on a display panel 2 and a current-position mark 22, such as a triangular mark indicating a current position, displayed on the road map, the map type road display panel being characterized in that perspective is imparted by giving gradations to a background color radially from the current-position mark. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
