A display system applied to a vehicle includes a navigation device guiding a route to a destination and a display control device displaying multiple route guidance contents in superimposed manner on a road surface using a head-up display. When the navigation device determines that a first route guidance and a second route guidance included in route guidance information are successive guidance, (i) the navigation device concurrently displays images of the first route guidance and the second route guidance, and (ii) the display control device activates display of a first guidance content that performs the first route guidance, and then activates display of a second guidance content that performs the second route guidance after deactivating the display of the first guidance content.

Provided is a center device that enables a navigation device to conduct guidance according to a route on the basis of the latest map information, without imposing a heavy load on a communication network. The center device calculates a guide route as a center route on the basis of the latest of the map information and information received from the navigation device, specifies the map information that is available to the navigation device, and calculates a guide route as a navigation route on the basis of the specified map information and the information received from the navigation device. On the basis of the center route and the navigation route, the center device specifies, from the map information, different map information necessary for the navigation device to give guidance on the center route, and transmits the specified map information to the navigation device.

Center device, program, map information transmission method, and navigation device

A navigation apparatus in a vehicle displays road names of cross roads that crosses a to-be-traveled road along the to-be-traveled road at positions that area adjacent to respective cross roads. In this manner, a user of the navigation apparatus easily recognizes the road names of the roads to be traveled by the vehicle in his/her view.

Navigation apparatus

A screen display apparatus includes an operation information reception unit that receives operation information regarding an inclination direction and an inclination angle of a joystick from the joystick, and a screen controller that performs a scroll process for scrolling a screen and a zoom process for zooming based on the operation information. The screen controller scrolls the screen according to the inclination direction and the inclination angle of the joystick, and continues a zoom-out process for zooming-out of the screen based on a detection of the inclination angle that is greater than a predetermined angle for a predetermined period until detecting the inclination angle of the joystick to be equal to or smaller than the predetermined angle or until zooming out to a predetermined minimum zoom rate.

In a map display device, a viewing angle for a three-dimensional road map can be changed horizontally on a screen so that the three-dimensional road map is generated at a standard viewing angle (45&#xb0;) up to a wide viewing angle (90&#xb0;). At this time, the viewing angle is changed based on a reference line passing through a current position of a subject vehicle where the map display device is mounted.

Map display device and map display method

A map display device, which imparts a perspective feeling to a route guidance line so that it can be easily viewed, when buildings and roads are three-dimensionally displayed. A map display device having a control unit for three-dimensionally displaying a map and further three-dimensionally displaying a route guidance line on a road on the map. When the route guidance line is hidden by a building, the control unit displays overlapped portion of the route guidance line in a color different from the color of the portions that are not overlapping. In particular, the control unit draws picture by a semitransparent method in which the color displaying the route guidance line and the color displaying the building are alternately changing with a pixel as a unit on the video RAM (VRAM). In this case, a positional relationship becomes clear between the route guidance line and the building, and the route guidance line can be seen more clearly.
