Abstract
A drive device includes a drive controller. The drive controller controls a drive signal on which a high-frequency drive signal is superimposed on a drive current to drive a movable frame and which is to be applied to a drive coil. The drive controller drives the movable frame to a predetermined position based on a detection signal detected by a detector and a high-frequency signal of a predetermined frequency band including a frequency of the high-frequency drive signal that is generated in a detection coil when the drive signal is applied to the drive coil.
