Abstract
An electronic device has a storage unit that stores unit information relating to movement with respect to each of an elevating state and a horizontal movement state and an altitude measurement unit that measures a series of altitudes. An altitude change determination unit determines whether the movement is the elevating state or not using a first determination section having a first altitude range based on a first set of altitudes within the measured series of altitudes, and determines whether the movement is the horizontal movement state or not using a second determination section having a second altitude range smaller than the first altitude range and based on a second set of altitudes within the measured series of altitudes. A movement distance calculator reads from the storage unit the unit information corresponding to the state determined by the determination unit and calculates a movement distance based on the read unit information.
