Abstract

There is provided a navigation device having a current location detection unit for detecting a current location, a current location correction unit for correcting the current location detected by the current location detection unit using map matching and a display unit for displaying a map, 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.

Claims

1. A navigation device, comprising:

a current location detection unit for detecting a current location;

a current location correction unit for correcting the current location detected by the current location detection unit using map matching; and

a display unit for displaying a map,

wherein the navigation device

switches an operation mode between a normal mode being an operation mode based on in-vehicle use and a pedestrian mode being an operation mode based on use when moving on foot,

displays the map of the current location in 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 in 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.

2. The navigation device according to claim 1, comprising:

traveling direction detecting means for detecting a traveling direction based on change of the current location detected by the current location detection unit, or change of the current location corrected by the current location correction unit,

wherein the navigation device

changes a direction of the map based on the traveling direction detected by the traveling direction detecting means, and holds the direction on the map corresponding to the traveling direction detected by the traveling direction detecting means in an upward direction of the display screen in the normal mode, and

stops changing the direction of the map according to the traveling direction, and changes the direction of the map in response to the operation of the user for display in the pedestrian mode.

3. The navigation device according to claim 2,

wherein a mark indicating the current location in the normal mode is a mark indicating the traveling direction, and

a mark indicating the current location in the pedestrian mode is a mark without directionality.

4. The navigation device according to claim 1, wherein the navigation device

receives setting of a destination in the pedestrian mode, and

displays a mark indicating the destination on the map and displays a distance from the current location to the destination.

5. The navigation device according to claim 1, wherein the navigation device

receives setting of a plurality of destinations in the pedestrian mode,

displays a mark indicating the destination on the map, and

sequentially selects the plurality of destinations, sets the selected destination to be identifiable from other destinations, and displays a distance to the selected destination.

6. The navigation device according to claim 1, wherein the navigation device

receives setting of a plurality of destinations in the pedestrian mode,

sequentially selects the plurality of destinations, and

changes a scale, a direction and a display location of the map, and displays the map by arranging a mark indicating the selected destination and a mark indicating the current location on positions on both ends in a longitudinal direction of a display screen.

7. The navigation device according to claim 1, wherein the navigation device

receives setting of a plurality of destinations in the pedestrian mode,

alternately executes a separate display of the plurality of destinations and an entire display of the plurality of destinations,

in the separate display:

sequentially selects the plurality of destinations,

changes a scale, a direction and a display location of the map, and displays the map by arranging a mark indicating the selected destination and a mark indicating the current location on positions on both ends in a longitudinal direction of the display screen, and

in the entire display;

changes the scale, the direction and the display location of the map, and displays the marks indicating the plurality of destinations and the current location on the display screen.

8. A display method of a navigation device having

a current location detection unit for detecting a current location,

a current location correction unit for correcting the current location detected by the current location detection unit using map matching, and

a display unit for displaying a map,

the method comprising:

an operation mode switching step of switching an operation mode of the display unit between a normal mode being an operation mode based on in-vehicle use and a pedestrian mode being an operation mode based on use when moving on foot;

a normal mode map displaying step of displaying 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

a pedestrian mode map displaying step of displaying 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.

9. A program of a display method of a navigation device,

wherein the navigation device has

a current location detection unit for detecting a current location,

a current location correction unit for correcting the current location detected by the current location detection unit using map matching,

a display unit for displaying a map, and

a calculation unit for executing the program of the display method to control operation of each unit, and

the program of the display method has

an operation mode switching step of switching an operation mode of the display unit between a normal mode being an operation mode based on in-vehicle use and a pedestrian mode being an operation mode based on use when moving on foot,

a normal mode map displaying step of displaying 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

a pedestrian mode map displaying step of displaying 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.

10. A recording medium for recording a program of a display method of a navigation device,

wherein the navigation device has

a current location detection unit for detecting a current location,

a current location correction unit for correcting the current location detected by the current location detection unit using map matching,

a display unit for displaying a map, and

a calculation unit for executing the program of the display method to control operation of each unit, and

the program of the display method has

an operation mode switching step of switching an operation mode of the display unit between a normal mode being an operation mode based on in-vehicle use and a pedestrian mode being an operation mode based on use when moving on foot,

a normal mode map displaying step of displaying 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
