Abstract:
1. A lens-controlling device for controlling a first lens unit which moves for zooming and a second lens unit which moves for focusing, the lens-controlling device comprising: a memory which stores data for obtaining target-position information representing a target position to which the second lens unit is to be moved, the target position corresponding to a position to which the first lens unit is moved from a current position; a controller which generates the target-position information on the basis of the data stored in the memory and controls the movement of the second lens unit on the basis of position information of the first lens unit and the target-position information; and a detector which detects a distance to an object to be focused on, wherein the controller selects data items to be used from the data stored in the memory on the basis of a detection result obtained by the detector.
