摘要： A camera assembly comprises a lens assembly (20) supported on a support structure (4), wherein the lens assembly includes an autofocus actuator arrangement (24) and the camera assembly includes an optical image stabilization assembly (40) arranged to move the lens assembly in a plane perpendicular to the optical axis. A flexible printed circuit tape (103) connected between the support structure (4) and the lens assembly (20) and providing an electrical connection to the autofocus actuator arrangement (24) is bent around a comer, thereby allowing the flexible printed circuit tape (103) to accommodate the motion of the lens assembly perpendicular to the optical axis. A crimp plate (62) connected to the lens assembly which crimps shape memory alloy wires (80) has features (63) extending out of the plane of the crimp plate for reducing flexibility. At least part of the optical image stabilzation assembly overlaps the lens assembly in the direction along the optical axis, thereby reducing the height of the camera assembly.

摘要： An actuator arrangement for use in a camera is disclosed. The camera comprises two or more camera elements including an image sensor and one or more optical elements for forming, or aiding forming of, an image of an object on the image sensor. The actuator arrangement comprises: a first part defining a first axis; a first actuator for providing a first type of movement of one or more of the camera elements relative to the first part; a second actuator for providing a second, different type of movement of one or more of the camera elements relative to the first part; a controller configured to (a) cause the first actuator to move one or more of the camera elements so as to provide a first optical image stabilisation (OIS) effect, and (b) cause the second actuator to move one or more of the camera elements so as to provide a second OIS effect. The first and second OIS effects combine to provide an overall OIS effect that is greater than either of the first and second OIS effects.
