Patent ID: 7840343

Claim:
A mobile terminal equipped with a map display function, comprising: a 2-dimensional code reading device to read a 2-dimensional code established at a particular location, the 2-dimensional code including position information of the particular location and corresponding recorded azimuth information for indicating the azimuth at the location, in relation to a 2-dimensional code read reference orientation, as an angle between north bearing and the 2-dimensional code read reference orientation, and to determine an angle deviation from which the 2-dimensional code was read by the 2-dimensional code reading device, and the 2-dimensional code reading device outputs the position information, the 2-dimensional code read reference orientation, the azimuth information, and the angle deviation from which the 2-dimensional code was read; a rotation angle calculation device to calculate a rotation angle at which a map is to be displayed so that the map is viewed properly from the angle deviation from which the 2-dimensional code was read according to the 2-dimensional code read reference orientation and the angle to the 2-dimensional code read reference orientation, which angle is azimuth information to calculate the rotation; map rotation device to rotate the map obtained based on the position information according to the rotation angle; and a display device to display the rotated map.
