PROBLEM TO BE SOLVED: To enable intuitive understanding of the location of updated portion in an electronic apparatus, having map-displaying function and capable of partially updating map data. SOLUTION: When displaying of a map is done by using map data after updating (S30: YES), at least either of the display attributes of an updated section and a non-updated section is changed, in response to updated history information read by an S20, and displaying of the map is conducted under the condition that both sections be distinguishable (S50). When changing the display attributes, realization thereof can be considered by changing at least one from among, for example, attributes such as color, brightness, and line thickness. In this case, the updated section may be changed from a normal display attribute, and conversely, non-updated section may be changed from a normal display attribute. Naturally, both may be changed together. Also, for example, the updated section may be highlight displayed. COPYRIGHT: (C)2005,JPO&NCIPI |
