Abstract

When displaying map information including a place where a 2-dimensional code is set according to the information containing the 2-dimensional code, the map can be displayed in a direction facilitating a user to view the map. A mobile terminal includes 2-dimensional code read means for reading a 2-dimensional code set at a particular location and containing position information on the location where it is set and the azimuth information on the location with respect to the read reference direction of the 2-dimensional code. The mobile terminal further includes display means for displaying a map, rotation angle calculation means, and map rotation means. The 2-dimensional code read means outputs position information recorded in the 2-dimensional code and the 2-dimensional code read reference direction and azimuth information. The rotation angle calculation means calculates a rotation angle from the 2-dimensional code read reference direction and azimuth information. The display means displays a map including the 2-dimensional code setting position rotated according to the rotation angle.
