An image display device is provided that includes an information storage device in which names of destinations are stored; name obtaining unit for obtaining names from the information storage device on the basis of an input device and its operation; a display for displaying character strings on a menu screen; a name display unit for displaying names obtained by the name obtaining unit in respective rows in a plurality of areas on the menu screen; and a display change unit for displaying character strings of names in a plurality of rows upon determining whether character strings of names to be displayed cannot fit in the display area. When the operator operates the input device, names are obtained from the information storage device and if character strings of names to be displayed cannot fit in the display areas, the character strings of the names are displayed in a plurality of rows.

Image display device, method of image display, and storage medium for storing image display programs

A navigation apparatus for displaying a map and including a data storage unit for storing map data, a man-machine interface having a display memory and picture drawing capability for expansion and visualization of display data, for acquiring display data to draw it into the display memory, and for setting up and displaying a display range of graphics; and a navigation data processor for reading map data out of the storage unit, for inputting of locations and present position tracking, and for outputting to the man-machine interface display data to be expanded and drawn in the display memory.

Navigation apparatus with navigation data processor and man-machine interface

A vehicle navigation system is presented for performing guidance along route which produces an intersection image upon controlling a drawing area of the intersection image on the basis of information and route regarding the intersection existing on the route which requires guidance. The navigation system display control unit determines the drawing area of the intersection image on the basis of map information stored in a memory, route information stored in a route memory and information concerning an intersection requiring route information and guidance prior to producing the intersection image. In addition, the display control unit judges whether the intersection which requires route guidance is larger than the predetermined limited scale rate, and if the intersection which requires guidance is larger than the predetermined image limit, the display control unit controls a display area by reducing the scale rate so as to be able to display the entire intersection or otherwise controls the display area so as to be able to display all routes within its intersection.

Vehicle navigation system and method

A vehicle navigation system is made to generate bitmap image data necessary for navigation, including map data, road data, font data, etc., and then to transmit a pattern (font) image and an enlarged intersection image to a display.
