    Abstract: Various embodiments include a camera with a voice coil motor (VCM) actuator assembly to provide autofocus (AF) and/or optical image stabilization (OIS) movement. The VCM actuator assembly is configured to move an image sensor of the camera in three dimensions (e.g. X, Y, and Z) to provide the AF and/or OIS movements. The VCM actuator assembly is asymmetrical and includes an at least partially open side that allows an optical assembly of the camera to pass through the open side of the VCM actuator. In some embodiments, the optical assembly is part of a folded optics arrangement of the camera that includes one or more prisms/and or lenses.

    Abstract: Various embodiments include a camera with a folded optics arrangement and include a voice coil motor (VCM) actuator assembly to provide autofocus (AF) and/or optical image stabilization (OIS) movement. The camera with folded optics and the associated VCM actuator assembly have a first rotational normal mode of free vibration such that lenses of the camera rotate about an optical axis of the camera such that the rotational motion in the first rotational mode of free vibration is invisible from a perspective of an image sensor of the camera.

    Abstract: Some embodiments include a camera system having a first camera unit and a second camera unit. The first camera unit may include a first actuator. The second camera unit may include a second actuator. In some embodiments, the first actuator may move one or more components of the first camera unit to provide autofocus and/or optical image stabilization functionality to the first camera unit. In some embodiments, the second actuator may move one or more components of the second camera unit to provide autofocus and/or optical image stabilization functionality to the second camera unit. In some examples, the first camera unit may be configured to capture a first image of a first visual field. The second camera unit may be configured to capture, simultaneously with the first camera unit capturing the first image, a second image of a second visual field.

    Abstract: Some embodiments of a camera unit of a multifunction device include an actuator for moving the optical package relative to the image sensor. In some embodiments, the actuator includes one or more lateral magnets situated at one or more sides of the optical package. In some embodiments, the actuator includes one or more optical image stabilization coils for circulating electric current in a plane perpendicular to the an optical axis of the optical package to generate magnetic interactions with a respective one of the one or more lateral magnets. In some embodiments, each of the optical image stabilization coils has an interior surface boundary, and a space enclosed by the interior surface boundary has a width smaller at a center of a length of the optical image stabilization coil than at the ends of the optical image stabilization coil.

    Abstract: In some embodiments, a camera unit of a multifunction device may include an optical package and an actuator for moving the optical package. In some embodiments, the actuator may include an asymmetric magnet arrangement. The asymmetric magnet arrangement may include a lateral position control magnet situated at a first side of the optical package, and a pair of transverse position control magnets situated at respective second and third sides of the optical package opposite one another with respect to an axis between the optical package and the lateral magnet. In some embodiments, the actuator may include one or more position sensor magnets attached to the optical package, and one or more magnetic field sensors for determining a position of the position sensor magnets.

    Abstract: A camera module includes an optical package, a camera actuator for moving the optical package, a camera subassembly, and one or more resilient members arranged within the camera subassembly to prevent, reduce, or cushion contact between the optical package and other components of the camera. The resilient members may be mounted on the lens carrier of the optical package and configured to come into resistive contact with components of the camera subassembly and/or mounted on components of the camera subassembly and configured to come into resistive contact with the optical package. In either case, the resistive cushioning provided by the resilient members may reduce or prevent contact (and an associated rattling noise associated with the contact) between the optical package and the hard components of the camera subassembly. The resilient members may be configured to cushion, but also allow hard stop contact. In embodiments bumpers (e.g., elastomeric pads) may be used.
