Abstract
A camera module includes an image sensor, a lens assembly, and a mechanical actuator. The lens assembly is positioned to focus an image on the image sensor and includes a variable focus lens. The mechanical actuator causes relative translation between the lens assembly and the image sensor in each of an X-direction parallel to a first lateral axis and a Y-direction parallel to a second lateral axis. The first lateral axis is substantially perpendicular to an optical axis of the lens assembly, and the second lateral axis substantially perpendicular to each of the optical axis and the first lateral axis. The lens assembly is fixed relative to the image sensor in each of a first rotational direction about the first lateral axis and a second rotational direction about the second lateral axis.
