Map image display device, map image display method and map image display program
First Claim
1. A map image display device comprising:
- a display unit applied with a command input to provide a display of a map image in response thereto;
a memory unit storing regional surface areas of particular areas in the map image and particular designations indicative of the particular areas in a correlated relationship;
a standard surface area setting unit dividing a surface area of an entire area indicated in the map image into n (n is an integer) equal divisions, when providing a display of the map image, to provide a resulting value that is determined to be a standard surface area;
a selecting unit retrieving the regional surface areas of the areas, involved in the map image to be displayed and indicative of the particular designations, from the memory unit and selecting the particular designations of n pieces of the areas whose surface areas are closer to the standard surface area; and
a display control unit compelling the n pieces of the particular designations, selected with the selecting unit, to be displayed on the map image at appropriate locations thereof as icons, indicative of an index of the command input in a superimposed relationship.

Abstract
A map image display device, a map image display method and a map image display program are disclosed. Upon determination of a map image for an objective to be displayed in response to a user'"'"'s command input, a standard surface area setting unit 21 divides a surface area of a whole area shown in the map image to be displayed into n equal divisions to assign resulting values to standard surface areas. Then, a particular designation selecting unit 16 selects n pieces of relevant particular designations of areas, whose surface areas are closer to the standard surface areas, among areas involved in the map image for the objective to be displayed. A display image preparing unit 17 prepares image data to cause the selected n pieces of the relevant particular designations to be displayed on the map image as icons, and a display control unit 18 controllably drives the display unit based on image data. This causes the map image, determined responsive to the user'"'"'s command input, to be displayed over the display unit, while enabling the n pieces of the particular designations to be displayed on the map image as the icons in a superimposed manner.

7. A method of providing a display of a map image, comprising:
-
providing a display of a map image in dependence on a command input received from a user;
storing regional surface areas of particular designations in the map image and particular designations indicative of the particular designations in a correlated relationship, respectively;
setting a standard surface area by dividing a surface area of an entire area indicated in the map image into n (n is an integer) divisions, when providing a display of the map image, to provide a resulting value that is determined to be the standard surface area;
selecting the particular designations of n pieces of the areas whose surface areas are closer to the standard surface area upon retrieving the regional surface area of the area, involved in the map image to be displayed and indicative of the particular designation, from the memory unit; and
controlling a display of the n pieces of the particular designations, selected with the selecting unit, to be provided on the map image at appropriate locations thereof as icons, indicative of an index of the command input, in a superimposed relationship. - View Dependent Claims (8, 9, 10, 11, 12)

13. A map image display program, comprising:
-
providing a display of a map image in dependence on a command input received from a user;
storing regional surface areas of particular designations in the map image and particular designations indicative of the particular designations in a correlated relationship, respectively;
setting a standard surface area by dividing a surface area of an entire area indicated in the map image into n (n is an integer) equal divisions, when providing a display of the map image, to provide a resulting value that is determined to be the standard surface area;
selecting the particular designations of n pieces of the areas whose surface areas are closer to the standard surface area upon retrieving the regional surface area of the area, involved in the map image to be displayed and indicative of the particular designation, from the memory unit; and
controlling a display of the n pieces of the particular designations, selected with the selecting unit, to be provided on the map image at appropriate locations thereof as icons, indicative of an index of the command input, in a superimposed relationship. - View Dependent Claims (14)
