First Claim
1. A vehicle navigation device comprising:
- (a) a storage memory for storing road map data;
(b) a character generator;
(c) a reproduction unit having;
(i) a picture memory; and
(ii) a display screen for displaying maps in color and having an input coupled with the picture memory;
(d) a map element selector for selecting map elements from the road map data;
(e) a control unit, including a picture composition unit for;
(i) loading a road map selected from the road map data into the picture memory, in response to the map element selector, which selected road map represents an area around a selected map element;
(ii) loading a name, generated for the selected map element by the character generator, into a predetermined segment of the picture memory;
(iii) superposing a pattern, within at least one first shape which corresponds to a shape of the selected map element, for display according to a predetermined representation standard, on data which represents the selected map element, which predetermined representation standard is distinct from standards used for displaying other map elements; and
(iv) superposing the pattern, within at least one second shape which corresponds to a shape of either the segment or the generated name, for display according to the predetermined representation standard, on data which represents either the segment or the generated name.

Abstract
A vehicle navigation device including a control unit, storage memory, reproduction unit and map element selector. Road map data is stored in the storage memory. The map element selector selects elements from the road map data. The reproduction unit includes a picture memory and a display screen. The control unit includes a picture composition unit for loading a road map selected from the road map data into the picture memory. The road map represents an area around a selected map element. The picture composition unit also loads a name, generated for the selected map element by the character generator, into a predetermined segment of the picture memory. The picture composition unit also superposes a pattern of data which represents the selected map element. The pattern is displayed according to a predetermined representation standard and is superposed either on the segment or on the generated name. The predetermined representation standard is distinct from standards used for displaying other map elements.
