A smartphone (1) according to an embodiment of the present disclosure includes an acceleration sensor (15) and at least one controller (10). The acceleration sensor (15) detects accelerations in three axes. The at least one controller (10) controls various functions based on the accelerations in the three axes of the acceleration sensor (15). Based on accelerations in two axes out of the three axes, the at least one controller (10) changes an offset of an acceleration in the remaining one axis. The at least one controller (10) determines a moving state from a plurality of moving states based on the accelerations and, when the determined moving state is a predetermined moving state, based on the accelerations in the two axes out of the three axes, changes the offset of the acceleration in the remaining one axis.
