    Abstract: In some embodiments, a first camera unit of a multifunction device for capturing a first image of a first visual field includes a first actuator for moving a first optical package. A second camera unit includes a second actuator for moving a second optical package. The second camera unit includes a second central magnet array situated along the axis between the first optics package of the first camera unit and the second optics package of the second camera unit. In some embodiments, the second central magnet array includes a second central upper magnet having a first polarity and a second central lower magnet having a polarity antiparallel to the first polarity. In some embodiments, the second camera unit includes a second distal magnet array situated opposite the second central magnet array with respect to the second optics package of the second camera unit.

    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: 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.
