Abstract
A navigation apparatus and method of displaying a map are provided for scrolling and displaying the map covering the vicinity of a present position such that a relationship with the present position can be constantly recognized. When a request for a surrounding scroll starting operation is accepted from a user, a display range is moved upward until the present position is located in the center of a lower hem of the display range of the map, that is, until an upper half of a present position mark is positioned in the center of a bottom of the display range. Then, the display range is moved in stages, i.e. in such a manner that the present position is moved to a lower left edge thereof, to an upper left edge thereof, to an upper right edge thereof, and to a lower right edge thereof, in this order. Thereafter, the display range is gradually moved rightward until the present position is located in the center of the lower hem of the display range. Finally, the display range is gradually moved downward until the present position returns to the original position located before starting the first surrounding scroll process.
