Abstract

A navigation device is provided with a current location detection unit for detecting a current location, a current location correction unit for correcting the current location detected by the currentlocation detection unit using map matching and a display unit for displaying a map. The navigation device switches an operation mode between a normal mode, which is an operation mode based on in-vehicle use, and a pedestrian mode, which is an operation mode based on use when moving on foot, displays the map of the current location by the display unit by arranging a mark indicating the current location based on the current location corrected by the current location correction unit in the normal mode, and displays the map of the current location by the display unit by arranging the mark indicating the current location based on the current location detected by the current location detection unit in the pedestrian mode.

Description

technical field [0001] The present invention relates to a navigation device, a display method of the navigation device, a program of the display method of the navigation device, and a recording medium recording the program of the display method of the navigation device, and can be applied as a personal navigation device ( PND) car navigation equipment. The present invention displays a map in which the mark of the current position is arranged on the current position corrected by map matching in normal mode, and displays the map in a manner of stopping correction by map matching in walking mode, thereby preventing Wrong display of current position when used as PND. Background technique [0002] In the prior art, a vehicle navigation device detects a current location using a global positioning system (GPS) and displays the detected current location on a map display. However, it is difficult to prevent errors in the detection of the current position by the GPS. On the other h...
