Samsung patents camera lens system with shared magnetic parts for focus and shake reduction

Patent drawing
Patent drawing from the official filing.

Samsung describes a camera module where the auto-focus mechanism sits inside the optical image stabilization (OIS) unit. The design uses a single magnetic component to drive both the focus movement and one axis of the shake-reduction movement, reducing the number of parts needed. Small balls are used to allow these moving parts to slide smoothly within the housing.

Why it mattersThis design aims to make phone cameras more compact by combining two separate mechanical functions into one shared structure.

In the filing’s own words

A camera module may include: an OIS, which moves in the direction perpendicular to an optical axis and includes a first OIS guide and a second OIS guide; an AF, which includes an AF guide, is disposed inside the OIS and moves in the optical axis direction; a first magnetic body disposed in the first OIS guide; a second magnetic body disposed in the second OIS guide; a first OIS coil, facing one surface of the first magnetic body and allowing the OIS to move in the first axis direction perpendicular to the optical axis; a second OIS coil allowing the OIS to move in the second axis direction perpendicular to the optical axis and the first axis; an AF coil, fixed to the AF guide unit and allowing the AF to move along the optical axis; an AF ball disposed between the AF guide and the first OIS guide; and an OIS ball disposed between a camera housing and the OIS.

What exactly they claim (claim 1)

1. An electronic device including a camera module, wherein the camera module comprises: a lens unit including at least one lens; an optical image stabilization (OIS) structure including a coil configured to move in a direction perpendicular to an optical axis (OA) of the lens unit and including a first OIS guide and a second OIS guide; an auto focus (AF) structure including an AF guide facing the first OIS guide, having at least a portion disposed inside the OIS structure, and configured to move in an optical axis direction of the lens unit; a camera housing configured to cover the OIS structure and the AF structure; a first magnetic body disposed in the first OIS guide and having at least a portion facing the AF guide; a second magnetic body disposed in the second OIS guide; a first OIS coil facing one surface of the first magnetic body and configured to generate an electromagnetic force with the first magnetic body so that the OIS structure moves in a first axial direction perpendicular to the optical axis; a second OIS coil facing one surface of the second magnetic body and configured to generate an electromagnetic force with the second magnetic body so that the OIS structure moves in a second axis direction perpendicular to the optical axis and the first axis; an AF coil fixed to the AF guide and facing the other surface of the first magnetic body, and configured to generate an electromagnetic force with the first magnetic body so that the AF structure moves along the optical axis; at least one AF ball disposed between the AF guide and the first OIS guide; and an OIS ball disposed between the camera housing and the OIS structure.
