Abstract
A map display apparatus and a map display method facilitate detection of relationship between the destination (current position) and the peripheral condition even when a detailed map is to be displayed on the narrow display area. The map display terminal displays a particular position, a current position, a destination, on a map by deriving the current position on the basis of a position information from a satellite. The map display apparatus has first means for displaying a wide area map having smaller reduced scale than a detailed map and centered at said current position upon displaying said detailed map centered at said current position.
Claims17
A map display method that displays maps of a current position on a map display terminal and derives said current position from a Global Positioning System (GPS), the method, comprising:
- initially displaying a wide area map;
- and
- automatically magnifying said wide area map in a step-by-step manner to display at each step a magnified map until a most highly magnified map is displayed,
- wherein map displays of said wide area map, said magnified map, and said most highly magnified map are centered on said current position.
A map display method that displays maps of a current position on a map display terminal and derives said current position from a Global Position System (GPS), the method, comprising:
- initially displaying a wide area map;
- automatically magnifying said wide area map in a step-by-step manner to display at each step a magnified map until a most highly magnified map is displayed;
- and
- downloading map display information of said most highly magnified map from a server,
- wherein said automatically magnifying said wide area map in a step-by-step manner depends upon progress of said downloading map display information of said most highly magnified map information.
A storage medium for storing a map display control program that displays maps of a current position on a map display terminal and derives said current position from a Global Positioning System (GPS),
- wherein said map display control program initially displays a wide area map and automatically magnifies said wide area map in a step-by-step manner to display at each step a magnified map until a most highly-magnified map is displayed, and
- wherein map displays of said wide area map, said magnified map, and said most highly magnified map are centered on said current position.
A map display terminal for displaying a current position of said map display terminal on map displays by deriving said current position from a Global Positioning System (GPS), said map display terminal, comprising:
- a read-only memory (ROM) including map display information for a wide area map;
- a central processing unit (CPU);
- a display block including a liquid crystal display (LCD) and an LCD controller under control of said CPU that initially displays said wide area map, automatically magnifies said wide area map in a step-by-step manner to display at each step a magnified map until a most highly magnified map is displayed, and centers map displays of said wide area map, said magnified map, and said most highly magnified map on said current position;
- and
- a GPS block including a GPS radio receiver and a GPS decoder that derives said current position.
