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.
