Abstract
A portable mobile terminal includes: a detection control unit; and a movement trajectory calculation unit configured to calculate a movement trajectory of a terminal body based on a detection result of an absolute position of the terminal body by the absolute position detecting unit and an acquisition result of a line segment indicating a rectilinear distance of the terminal body by a link information generation unit. The detection control unit determines a timing that comes every given time as a tentative detection timing, and in a case where the link information generation unit has not acquired a new line segment till the tentative detection timing after a previous detection timing, the detection control unit determines a timing at which the link information generation unit acquires a new line segment next as a detection timing, and starts up the absolute position detecting unit.
