A navigation device includes: an intersection attribute determination unitthat determines a direction of a left/right turn at a guidance target intersection on a guidance route on the basis of route information on the guidance route; a display position decision unitthat decides a display position for a name of the guidance target intersection on a side opposite to the direction of the right/left turn determined by the intersection attribute determination unitwhen viewed from an entrance link to the guidance target intersection; a drawing data generation unitthat generates drawing data on the name of the guidance target intersection; and an image data output unitthat causes a display deviceto display the drawing data generated by the drawing data generation unitat the display position decided by the display position decision unit

Navigation device for displaying name of guidance intersection

A navigation device includes a road periphery display change unitthat selects a road R which connects to, intersects with, or is adjacent to a guidance route/a travel plan routefrom a map database, and displays the road in a high contrast on the inside of a predetermined distance from the guidance route/the travel plan route, displays the road in a low contrast on the outside of the predetermined distance, and displays the road by changing continuously or stepwise a gradation in an intermediate region between the inside and the outside.

Navigation device

Disclosed is a navigation device including: a target candidate extracting unit for extracting target candidates located along a guidance route from a map database on a basis of a vehicle position, the guidance route, and intersection information about a target intersection for guidance; a target determining unit for determining a target on a basis of knowledge about target determination from among the target candidates extracted by the target candidate extracting unit; a guidance sentence generating unit for generating a guidance sentence by using the target determined by the target determining unit; and a sound output unit for outputting voice guidance on a basis of the guidance sentence generated by the guidance sentence generating unit.

A navigation device includes a map creation unit, a display unit, and a display controller. The display unit displays, on a map created by the map creation unit, roadside target facility symbols representing facilities as navigation targets that are located along the navigation route, on-map facility symbols representing facilities that differ from the facilities as the navigation targets on the created map, and facility display switching buttons for receiving operation of switching display/non-display of the on-map facility symbols by facility category. The display controller switches the display/non-display of the on-map facility symbols in accordance with the operation received through the facility display button, and, when the received operation indicates the display of the on-map facility symbols, control the display unit to display the on-map facility symbols in a different display mode from a display mode of the roadside target facility symbols.

Disclosed is a navigation device including a guidance route calculation unitfor calculating a guidance route by using point information about a destination, point information about a current position, and map information, a guidance map generating unitfor generating a guidance route map by using the calculated guidance route and the map information, a guidance route surrounding facility icon arrangement unitfor extracting a facility icon required for the calculated guidance route according to a facility icon extraction rule, and for determining an offset arrangement position of this facility icon, and a display unitfor attaching the facility icon at the above-mentioned determined offset arrangement position on the above-mentioned guidance route map to display the facility icon.
