Claim One:
1. A map image display device that displays at least a map image on a display screen, the device comprising: a map data acquisition unit configured to acquire map data; a display controller configured to display a three-dimensional map image containing at least a road image and a structure image on the display screen, based on the map data; a data extraction unit configured to extract extracted structure data, which is data of structures contained in an extraction range defined in advance with respect to a specific point as a datum, from the map data in a case where the specific point is designated on a map; and a landmark selection unit configured to select a structure, which corresponds to at least one item of extracted structure data among multiple extracted structure data items in a case where the multiple extracted structure data items are extracted, as a landmark structure, wherein the landmark selection unit selects at least one structure, the evaluated value of which is different from evaluated values of the other structures by a selection threshold value or greater, as the landmark structure based on the extracted structure data, the evaluated value relating to one or multiple selection indices defined in advance and wherein the display controller displays the structure image on the display screen in an emphasized manner such that the selected landmark structure offers visibility higher than visibility of non-emphasized structures which are structures other than the landmark structure.
