First Claim
Patent Images
1. An electronic device, comprising:
- a barometric pressure sensor detecting a barometric pressure;
a receiving unit receiving a positioning signal from a positioning satellite;
a storage unit storing a position of a way point which is a candidate of a spot used by a user and an altitude of the way point; and
a processor calculating an altitude by using the barometric pressure, a position calculated on the basis of the positioning signal, and the position of the way point and the altitude of the way point stored in the storage unit.
