  • Patent number: 11122197
    Abstract: Embodiments of the present disclosure pertains to a lens control apparatus that can be implemented in an imaging device to provide autofocus (AF) and image stabilization (IS) functionalities. The lens control apparatus includes a casing, a lens carrier movable in said casing and configured to hold an imaging lens, a pair of focusing coils disposed within said casing and configured to enable linear motion of the lens carrier along an optical axis, and a set of actuating coils disposed within said casing and configured to pivot the lens carrier in a first direction relative to the optical axis and a second direction relative to the optical axis, said first direction and said second direction being orthogonal to each other, and wherein the lens control apparatus is capable of providing at least three degrees of freedom to the lens carrier.
