摘要:
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.
