Electronic chart display device and method of displaying information relating to electronic chart
First Claim
1. An electronic map display device for displaying a status for each of a plurality of electronic maps, comprising:
- a license key acquirer configured to acquire a license key having a period of validity to use at least one of the electronic maps,a map information display determiner configured to determine whether each of the electronic maps is currently available for acquisition based on the license key; and
a map information display interface configured to display electronic map information for each of the electronic maps showing an exterior edge of a range recorded in each of the electronic maps, wherein the exterior edge indicates that the electronic map is currently available as determined by the map information display determiner, or the exterior edge indicates that the electronic map is currently not available as determined by the map information display determiner,wherein the map information display interface varies the exterior edge of each of the electronic maps depending on the status of the electronic map.

15. An electronic map display device for displaying a status for each of a plurality of electronic maps, comprising:
-
processing circuitry configured to acquire a license key having a period of validity to use at least one of the electronic maps, to determine whether each of the electronic maps is currently available; and to display electronic map information for each of the electronic maps showing an exterior edge of a range recorded in each of the electronic maps, wherein the exterior edge conveys information about whether the electronic map is currently available, and wherein, for a first electronic map that is available, the processing circuitry is further configured to vary the exterior edge of the first electronic map by displaying the exterior edge with a first line type indicating that the first electronic map is available, and for a second electronic map that is not available, the processing circuitry is further configured to vary the exterior edge of the second electronic map by displaying the exterior edge with a second line type indicating that the second electronic map is not available. - View Dependent Claims (16, 17, 18, 19, 20)
