INFORMATION ACQUISITION DEVICE, POSITIONAL INFORMATION STORAGE METHOD AND STORAGE MEDIUM

摘要

An information acquisition device includes: a positioning unit that measures a current position and acquires positional information thereof; an information acquisition unit that acquires information; a storage unit that stores information acquired by the information acquisition unit and positional information acquired by the positioning unit; and a control unit that causes the positioning unit to perform positioning, while the information acquisition unit is activated, at an interval shorter than while the information acquisition unit is stopped, and causes positional information acquired while the information acquisition unit is activated, outside a time period determined in advance with a time in which acquisition of information was performed by the information acquisition unit as a reference point, among positional information acquired in the positioning unit, to be thinned and stored in the storage unit.

1. An information acquisition device comprising:
a positioning unit that measures a current position and acquires positional information thereof; an information acquisition unit that acquires information; a storage unit that stores information acquired by the information acquisition unit and positional information acquired by the positioning unit; and a control unit that causes the positioning unit to sequentially perform positioning at a predetermined time interval, while the information acquisition unit is activated, controls the positional information acquired to be periodically thinned automatically and causes only remaining positional information to be stored in the storage unit in another time period to be periodically thinned automatically, and causes only remaining positional information to be stored in the storage unit in another time period other than a predetermined time period with a base point of time when acquisition of information by the information acquisition unit is performed while the information acquisition unit is activated, and causes a sequence of the positional information acquired to be stored in the storage unit without thinning in the predetermined time period.
