Map moving apparatus
First Claim
1. A map moving apparatus that automatically moves a map screen display region along a map feature displayed on a monitor, comprising:
- a monitor that displays in a map screen display region a map image based on stored map data, the map image including polygon figures defined by polygon data;
an external instruction input section that is configured to receive a shape input from a user in the map screen display region of the monitor;
an input shape recognizing section that is configured to recognize a shape that a user inputs to the map screen display region;
a polygon shape identifying section, that is configured to identify a polygon figure displayed in the map screen display region that approximates said input shape by comparing polygon figures, which are displayed on the map screen, with said input shape; and
a map movement processing section that is configured to move the map screen display region along said identified polygon figure.

Abstract
A map moving apparatus capable of performing desired map movement by a simple input operation without requiring a continuous operation by a user in moving a map screen display region is disclosed. An operated direction, an operated position, an operated speed and the like are detected from an input operation that a user performs on the map screen display region, and a map screen display region input shape recognizing section recognizes an input shape. A polygon shape identifying section extracts data having substantially the same shape as the recognized input shape from polygon data in map display data by using a matching method. When data having substantially the same shape exists, a type of the polygon is identified. In a movement mode selecting section, the movement of a screen map reverses direction when it reaches an end portion in the case where the polygon type is a linear shape, and the movement circulates to continue movement of the map screen where the type is a ring shape with no end portion. In the case where guidance information is detected during the movement of the map, guidance is provided on a screen or by voice.
