Abstract
A camera lens element is suspended on a support structure by balls that allow movement of the camera lens elementorthogonal to the optical axis and plural flexures connected between the support structure and the camera lens element to bias them against the balls while permitting said movement of the camera lens elementorthogonal to the optical axis. Lateral movement is driven by a lateral actuation arrangement comprising plural SMA actuator wires. The flexures provide a lateral biasing force that biases the camera lens element towards a central position. An electrical connection is made through the flexures from the support structure to the camera lens element. The flexures may be connected to laminated structures.
