Abstract
Official abstract text for this publication.
The present invention provides a lens device, a drive method, a recording medium, and an image capturing device. According to an aspect of the present invention, in an one-sided drive mode which allows the lens to move beyond a target position, and then to move in a reverse direction and stop at the target position, the control part controls the lens on the basis of the brake ON/OFF information so that when the lens is temporarily stopped, braking by the brake part is not applied, and only when the lens is stopped at a final target position, braking by the brake part is applied.
First claim
Opening claim text (preview).
What is claimed is: 1. A lens device to be mounted on an image capturing device body, the lens device comprising: a lens; a lens position detector for detecting a position of the lens; a lens driving part provided with an electric motor, the lens driving part transmitting driving force from the electric motor to the lens to allow the lens to move in an optical axis direction; a brake part for short-circuiting coils in the electric motor to stop the electric motor; a recept…
