Patent ID: 7692873

Claim:
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 first AF unit mounted in the lens-controlling device configured to detect an in-focus position of the second lens unit on the basis of a high-frequency component of an object image; a second AF unit mounted in the lens-controlling device configured to detect an in-focus position of the second lens unit by using different schemes from the first AF unit; a memory mounted in the lens-controlling device configured to store position data of the second lens unit and position data of the first lens unit, each position data corresponding to an object distance; and a controller mounted in the lens-controlling device configured to control a movement of the second lens unit on the basis of the position data of the second lens unit and the position data of the first lens unit in a case where the first lens unit moves, wherein the movement of the second lens unit by the controller is based on a detection result obtained by the second AF unit.
