PROBLEM TO BE SOLVED: To follow a change in altitude.SOLUTION: A portable electronic apparatus (for example, smartphone) 1 includes an atmospheric pressure sensor 19, an acceleration sensor 15, and a controller 10. The atmospheric pressure sensor 19 detects the atmospheric pressure acting on the portable electronic apparatus 1. The acceleration sensor 15 detects the acceleration acting on the portable electronic apparatus 1. The controller 10 detects the movement of the apparatus on the basis of the acceleration. The controller 10 corrects a change in the atmospheric pressure when the apparatus is moving on the basis of the change in the atmospheric pressure when the apparatus is not moving to calculate a change in the altitude of the apparatus. |
