TRAJECTORY DISPLAY DEVICE
First Claim
1. A trajectory display device comprising:
- a display element for displaying a trajectory of a moving body and a map;
a current position detector for detecting a current position of the moving body successively;
a memory for storing the current position successively so that a plurality of position data is stored; and
a position determination unit for determining a plurality of certain actual distance trajectory points and a plurality of direction change points based on the position data stored in the memory,wherein the certain actual distance trajectory points are arranged at every actual distance,wherein the actual distance is defined by a first scale of the map displayed on the display element in such a manner that the actual distance in case that the first scale of the map is small is longer than the actual distance in case that the first scale of the map is large,wherein the moving body changes a moving direction at each direction change point, andwherein the display element displays the trajectory including the certain actual distance trajectory points and the direction change points, which is overlapped over the map.

Abstract
A trajectory display device includes: a display element; a current position detector; a memory for storing the current position successively; and a position determination unit for determining a plurality of certain actual distance trajectory points and a plurality of direction change points based on position data stored in the memory. The certain actual distance trajectory points are arranged at every actual distance defined by a scale of a map. The moving body changes a moving direction at each direction change point. The display element displays the trajectory including the certain actual distance trajectory points and the direction change points, which is overlapped over the map.
