ABSTRACT:
A lens driving control apparatus comprising: a lens unit including a lens and a lens barrel in which the lens is incorporated; a frame configured to support the lens unit through springs such that the lens unit moves in a movable range in the optical axis direction; a voice coil motor including a driving coil to drive the lens unit in the optical axis direction; a motor driver configured to supply a driving current to the driving coil; and a driver controlling circuit configured to control the motor driver such that a standby time period to suppress vibration of the lens unit is set every time the lens unit moves a distance as a unit, which distance is obtained by dividing the movable range by a predetermined number.
