A stepping motor driving device which makes it possible to reduce electric power consumed by a stepping motor and at the same time suppress degradation of shake correcting performance. A CPU of the stepping motor driving device switches between a first driving method in which a first applied voltage is applied to the stepping motor and a second driving method in which each pulse is divided to apply the first applied voltage over a predetermined time period and then apply a second applied voltage to the stepping motor, depending on the state of the drive frequency of the stepping motor.
