Abstract: In some embodiments, a camera actuator includes an actuator base, an autofocus voice coil motor, and an optical image stabilization voice coil motor. In some embodiments, the autofocus voice coil motor includes a lens carrier mounting attachment moveably mounted to the actuator base, a plurality of shared magnets mounted to the base, and an autofocus coil fixedly mounted to the lens carrier mounting attachment for producing forces for moving a lens carrier in a direction of an optical axis of one or more lenses of the lens carrier. In some embodiments, the optical image stabilization voice coil motor includes an image sensor carrier moveably mounted to the actuator base, and optical image stabilization coils moveably mounted to the image sensor carrier within the magnetic fields of the shared magnets, for producing forces for moving the image sensor carrier in a plurality of directions orthogonal to the optical axis.

Abstract: Various embodiments include perimeter sheet spring suspension arrangements for cameras. A perimeter sheet spring suspension arrangement may be used to suspend a moveable platform of the camera from a base structure of the camera, and allow a lens group of the camera to move laterally. According to some embodiments, the perimeter sheet spring suspension arrangement may include one or more tabs that may be used as bumpers that cushion lateral movement of the moveable platform.

Abstract: Some embodiments include a camera system having a first camera unit and a second camera unit. The first camera unit includes an autofocus actuator. The autofocus actuator includes a first plurality of magnets for autofocus motion control of components of a first optical package. The first plurality of magnets is positioned to generate magnetic fields aligned in parallel with a first magnetic axis at a right angle to the optical axis of the first optical package. The second camera unit includes an optical image stabilization and autofocus actuator. The optical image stabilization and autofocus actuator includes a second plurality of magnets positioned to generate magnetic fields aligned along a second magnet axis at 45-degrees to the first magnetic axis. The second camera unit includes a third plurality of magnets positioned to generate magnetic fields aligned along a third magnetic axis at 135-degrees to the first magnetic axis.

Abstract: A folded camera may include folded optics arrangement positioned optically in front of an image sensor. The folded optics arrangement may include one or more light-folding elements and a lens group having one or more lens elements. Light may pass through the folded optics arrangement, within which the light be folded or redirected by the light-folding element, to focus on an image plane on the image sensor. The folded camera may include a shape-memory actuator having one or more shape-memory elements, whose lengths and/or shapes may be controlled by regulating individual temperatures of the shape-memory elements. The shape-memory actuator may move the lens group relative to the image sensor to implement various autofocus (AF) functions. The folded camera may include a voice coil motor (VCM) which may be controlled to move the image sensor relative to the lens group to perform various optical image stabilization (OIS) functions.
