MAP DISPLAY DEVICE FOR MOUNTING ON VEHICLE

摘要

PURPOSE:To allow the displaying of an easily visible map where characters do not overlap by moving the character information of this time to a position in the region of a prescribed range where this character information does not overlap on the already displayed character information and displaying this information in this position when the character information of this time and the already displayed character information overlap. CONSTITUTION:The non-character information is displayed at a prescribed size regardless of its display magnification by successively computing the display positions of respective sets of the character information of map information according to the display position of the non-character information. This display position is stored simultaneously therewith. The correlation between the character information of this time and the already displayed other character information is then computed and whether the character information of this time and the already displayed character information overlap or not is thereby decided. The character information of this time is moved to the position in the region of the prescribed range where this character information does not overlap on the already displayed character information. The character information of this time is displayed in this position. The character information is displayed within the region of the prescribed range from the actual position in this way and, therefore, the large difference from the actual position of the characters and the display position is eliminated and the easily visible map where the characters do not overlap is displayed.
