Abstract
Reducing a time when a navigation apparatus cannot be used by an update operation of data for displaying map to thereby avoid vexatious complication of update process. A navigation apparatus 100 reads out data for update from DVD in use of a DVD drive 106 to update data recorded in an HD for is playing map. In such the update, the navigation apparatus 100 precedently updates data corresponding to a map in the vicinity of a present position of vehicle, and simultaneously updates rest of the data in use of a vacant time of process.

A map depiction device which generates map image data for displaying map and outputs the map image data thus generated to a display device in association with traveling of a movable body comprising:
- a record device having a map file containing map data provided for each of a plurality of areas, obtained by dividing an entire region to be displayed on a map, to thereby generate the map image data of an area corresponding to an own file, and a common file containing at least administration data for administrating the map data contained in the map file;
- a present position data generating device for generating present position data indicative of at least a present position of the movable body;
- a display control device for generating the map image data corresponding to a peripheral map of the present position, which is indicated by the present position data with use of the administration data and the map file, and outputting the map image data to the display device;
- a detection device for detecting whether or not update of the map file is necessary;
- a determining device for determining the map file to be undated on the basis of the present position data when it is detected such that the update of the map file is necessary;
- and
- a file updating device which obtains the common file and the file data for update, corresponding to the map file determined by the determining device, and updates the common file and map file, which are recorded in the recording device, with use of the file data thus obtained after suspending process using the map file.
A navigation apparatus having a map depiction device which generates map image data for displaying a map and outputs the map image data thus generated to a display device in association with traveling of a movable body comprising:
- a record device having a map file, which contains map data provided for each of a plurality of areas obtained by dividing an entire region to be displayed on a map to thereby generate the map image data of an area corresponding to an own file, and a common file, which contains at least administration data for administrating the map data contained in the map file;
- a present position data generating device for generating present position data indicative of at least a present position of the movable body;
- a setup device for setting up a destination;
- a route setup device for setting up a route from the present position of the movable body to the destination;
- a display control device for generating the map image data so that route guide information indicative of a route which is set up along with a peripheral map of the present position, indicated by the present position data, is displayed with use of the administration data and the map file, and outputting the map image data to the display device in use of the administration data and the map file;
- a detection device for detecting whether or not update of the map file is necessary;
- a determining device for determining the map file to be updated on the basis of the present position data when it is detected such that the update of the map file is detected to be necessary;
- and
- a file updating device which obtains the common file and the file data for update, corresponding to the map file determined by the determining device, and updates the common file and map file, which are recorded in the recording device, with use of the file data thus obtained after suspending process using the map file.
A file update method in a map depiction device which generates map image data for displaying a map and outputs the map image data thus generated and has a recording medium that records a map file which is provided area by area and obtained by dividing an entire area to be displayed in a map to a plurality of the areas and includes map data for generating the map image data corresponding to the area corresponding to an own file, and administration data for administrating the map data which are contained in the map file, comprising steps of:
- a first step of detecting whether or not update of the map file is necessary in the map depiction device;
- a second step of generating present position data designating at least the present position of the movable body in the map depiction device;
- a third step of determining the map file to be updated on the basis of the present position of the vehicle in the map depiction device;
- and
- a forth step of obtaining the common file and the file data for update, corresponding to the map file determined in the third step, and updates the common file and map file, which are recorded in the recording device, with use of the file data thus obtained after suspending process using the map file.
An information recording medium recording a file update program for updating a plurality of files that are recorded in an information recording medium, the plurality of files being a map file containing map data provided for each of a plurality of areas, obtained by dividing an entire region to be displayed on a map, and a common file containing at least administration data for administrating the map data contained in the map file, the file update program being provided to update the map file and the common file with a computer, tangibly demonstrating function comprising steps of:
- a present position data generating device for generating present position data indicative of at least a present position of a movable body;
- a detection device for detecting whether or not update of the map file is necessary;
- a determining device for determining the map file to be updated on the basis of the present position data when it is detected such that the update of the map file is necessary;
- and
- a file updating device which obtains file data for update determined by the common file and the file data for update, corresponding to the map file determined by the determining device, and updates the common file and map file, which are recorded in the information recording device, with use of the file data thus obtained after suspending process using the map file.
