Samsung patents camera lens shifter using piezoelectric vibration

Samsung has filed a patent for a camera module that uses piezoelectric actuators to shift the lens or sensor sideways. The design employs two vibrating components to push on flexible parts, allowing for precise movement perpendicular to the line of sight.

Why it mattersThis mechanism could help improve image stabilization or focus adjustment in future phones by using small, fast-moving parts instead of traditional motors.

In the filing’s own words

A camera module is provided. The camera module includes a lens having an optical axis (OA), an image sensor configured to receive light passing through the lens, and a first piezoelectric actuator configured to move the lens or the image sensor in a direction that is orthogonal to the OA, wherein the first piezoelectric actuator includes a first vibrator configured to generate a vibration, a second vibrator configured to generate a vibration, a first moving body including a first elastically deformable region and a second elastically deformable region, a first tip configured to press the first elastically deformable region and configured to transmit the vibration generated from the first vibrator to the first elastically deformable region, and a second tip configured to press the second elastically deformable region and configured to transmit the vibration generated from the second vibrator to the second elastically deformable region.

What exactly they claim (claim 1)

1. A camera module comprising: a lens having an optical axis (OA); an image sensor configured to receive light passing through the lens; and a first piezoelectric actuator configured to move the lens or the image sensor in a direction that is substantially orthogonal to the OA, wherein the first piezoelectric actuator comprises: a first vibrator configured to generate a vibration, a second vibrator configured to generate a vibration, a first moving body comprising a first elastically deformable region and a second elastically deformable region, a first tip configured to press the first elastically deformable region and configured to transmit the vibration generated from the first vibrator to the first elastically deformable region, and a second tip configured to press the second elastically deformable region and configured to transmit the vibration generated from the second vibrator to the second elastically deformable region.
