Abstract: A mobile telephone device includes a control unit that determines that a state is a state of walking or a movement state different from the state of walking, based on acceleration. In a case in which the control unit determines that a state is the movement state different from the state of walking, if a state immediately before determining the movement state different from the state of walking is the state of walking, the control unit makes the determination valid. As an example, the movement state different from the state of walking is a state of moving on a bicycle or a state of moving by transportation other than the bicycle.
