     BACKGROUND 
     Technical Field 
     This disclosure relates generally to camera module components, and, more specifically, to the use of multiple cameras for zoom functions in mobile devices. 
     Description of the Related Art 
     The advent of small, mobile multipurpose devices such as smartphones and tablet or pad devices has resulted in a need for high-resolution, small form factor cameras, capable of generating high levels of image quality, for integration in the devices. 
     Increasingly, as users rely on multifunction devices as their primary cameras for day-to-day use, users demand features, such as zoom photography, that they have become accustomed to using in dedicated-purpose camera bodies. The zoom function is useful for capturing the details of a scene or alternatively capturing the context in which those details exist. The ability to change focal length to achieve zoom effects is sufficiently compelling to users of dedicated purpose cameras that it compels them to carry bags with an array of removable lenses, each of which weighs more and takes up more space than many common examples of a multifunction device, such as a phone. 
     Providing the zoom feature in a camera unit of a multifunction device has traditionally required moving mechanical parts that increase complexity and cost of the device. Such moving parts also reduce reliability of the device and take up valuable space inside the device, which puts the desire for zoom functions in direct conflict with the desire for smaller camera units that take up less space in the multifunction device. 
     SUMMARY OF EMBODIMENTS 
     Some embodiments provide a camera system (e.g., a dual camera system) having a first camera unit and a second camera unit.

Furthermore, the second actuator may be configured to move the second optical package along a second optical axis and/or along a second plane that is orthogonal to the second optical axis. The second optical package may include one or more lenses that define the second optical axis. 
     In various examples, the first actuator of the first camera unit may include one or more magnets and/or one or more coils for actuation along the first optical axis and/or along the first plane that is orthogonal to the first optical axis. For instance, at least one of the coils may be configured to receive a current that causes the coil to produce a magnetic field that interacts with at least one magnetic field of the one or more magnets. 
     In some embodiments, the second actuator of the second camera unit may include one or more magnets and/or one or more coils for actuation along the second optical axis and/or along the second plane that is orthogonal to the second optical axis.

     This specification includes references to “one embodiment” or “an embodiment.” The appearances of the phrases “in one embodiment” or “in an embodiment” do not necessarily refer to the same embodiment. Particular features, structures, or characteristics may be combined in any suitable manner consistent with this disclosure. 
     “Comprising.” This term is open-ended. As used in the appended claims, this term does not foreclose additional structure or steps. Consider a claim that recites: “An apparatus comprising one or more processor units . . . .” Such a claim does not foreclose the apparatus from including additional components (e.g., a network interface unit, graphics circuitry, etc.). 
     “Configured To.” Various units, circuits, or other components may be described or claimed as “configured to” perform a task or tasks. In such contexts, “configured to” is used to connote structure by indicating that the units/circuits/components include structure (e.g., circuitry) that performs those task or tasks during operation. As such, the unit/circuit/component can be said to be configured to perform the task even when the specified unit/circuit/component is not currently operational (e.g., is not on). The units/circuits/components used with the “configured to” language include hardware—for example, circuits, memory storing program instructions executable to implement the operation, etc. Reciting that a unit/circuit/component is “configured to” perform one or more tasks is expressly intended not to invoke 35 U.S.C. § 112, sixth paragraph, for that unit/circuit/component. Additionally, “configured to” can include generic structure (e.g., generic circuitry) that is manipulated by software and/or firmware (e.g., an FPGA or a general-purpose processor executing software) to operate in manner that is capable of performing the task(s) at issue. “Configure to” may also include adapting a manufacturing process (e.g., a semiconductor fabrication facility) to fabricate devices (e.g., integrated circuits) that are adapted to implement or perform one or more tasks. 
     “First,” “Second,” etc. As used herein, these terms are used as labels for nouns that they precede, and do not imply any type of ordering (e.g., spatial, temporal, logical, etc.). For example, a buffer circuit may be described herein as performing write operations for “first” and “second” values. The terms “first” and “second” do not necessarily imply that the first value must be written before the second value. 
     “Based On.” As used herein, this term is used to describe one or more factors that affect a determination. This term does not foreclose additional factors that may affect a determination. That is, a determination may be solely based on those factors or based, at least in part, on those factors. Consider the phrase “determine A based on B.” While in this case, B is a factor that affects the determination of A, such a phrase does not foreclose the determination of A from also being based on C. In other instances, A may be determined based solely on B.

For instance, the autofocus coils of the second VCM actuator may include a first autofocus coil disposed proximate the second magnet of the asymmetric magnet arrangement, and a second autofocus coil disposed proximate the third magnet of the asymmetric magnet arrangement. 
     In some embodiments, the first camera unit may be disposed adjacent to the second camera unit. For example, the first camera unit and the second camera unit may each be rectangular in plan, and the first camera unit may be disposed adjacent to the second camera unit along a first axis that intersects a second axis. For instance, the second axis may extend through the first optical package of the first camera unit and the second optical package of the second camera unit. The asymmetric magnet arrangement of the second VCM actuator may include a first magnet disposed proximate a first side of the second camera unit that is distal to the first axis. Furthermore, the first magnet may have a longitudinal axis that is parallel to the first axis. In some embodiments, no magnets are disposed proximate a second side of the second camera unit that is opposite the first side of the second camera unit. The second side of the second camera unit may extend in a direction that is parallel to the first axis. In some examples, a dummy mass may be disposed proximate the second side of the second camera unit that is opposite the first side of the second camera unit. The dummy mass may be configured to act as a counterbalance to the first magnet disposed proximate the first side of the second camera unit. In some embodiments, the asymmetric magnet arrangement of the second VCM actuator may further include a second magnet disposed proximate a third side of the second camera unit, and a third magnet disposed proximate a fourth side of the second camera unit that is opposite the third side of the second camera unit. 
     In some embodiments, 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 a second image of a second visual field. In some examples, the first camera unit and the second camera unit may be configured to simultaneously capture the first image of the first visual field and the second image of the second visual field, respectively. The second visual field may be a subset of the first visual field. Furthermore, in some embodiments, the first optical package of the first camera unit may be configured for a first focal length, and the second optical package of the second camera unit may be configured for a second focal length. The second focal length may be a different length than the first focal length. 
     In some embodiments, a method for capturing images with multiple cameras (e.g., multiple cameras of a multifunction device) may include capturing a first image of a first visual field and capturing a second image of a second visual field. The second visual field may be a subset of the first visual field. According to various examples, capturing the second image may occur simultaneously with capturing the first image. In some examples, the first image of the first visual field may be captured via a first camera unit. The first camera unit may include a first VCM actuator and a first optical package with a first focal length. The second image of the second visual field may be captured via a second camera unit. The second camera unit may include a second VCM actuator and a second optical package with a second focal length. The second focal length of the second optical package may be a different length than the first focal length of the first optical package. 
     In some embodiments, the method may include actuating movement of the first camera unit to provide optical image stabilization and/or focus (e.g., autofocus) to the first camera unit. For instance, movement of the first camera unit may be actuated via the first VCM actuator of the first camera unit. The first VCM actuator may include a symmetric magnet arrangement. Furthermore, the first VCM actuator may include multiple coils, and actuating movement of the first camera unit may include providing a current through one or more of the coils such that the current-receiving coil(s) interact with one or more magnets of the symmetric magnet arrangement. The coils may include at least one autofocus coil and a symmetric optical image stabilization coil arrangement. The autofocus coil may be configured to radially surround the first optical package and to provide focus to the first camera unit. The symmetric optical image stabilization coil arrangement may be configured to provide optical image stabilization to the first camera unit. 
     In some embodiments, the method may include actuating movement of the second camera unit to provide optical image stabilization and/or focus (e.g., autofocus) to the second camera unit. For instance, movement of the second camera unit may be actuated via the second VCM actuator of the second camera unit. The second VCM actuator may include an asymmetric magnet arrangement. Furthermore, the second VCM actuator may include at least one autofocus coil and an asymmetric optical image stabilization coil arrangement.

       FIG. 1A  illustrates a view of an example embodiment of camera module components arranged for multiple visual fields usable for a multiple camera system for portable zoom, according to at least some embodiments. A portable multifunction device  1080  includes a first optical sensor/camera unit  1082  with a first focal length  1090  for capturing a first visual field  1086  and a second optical sensor/camera unit  1084  with a first focal length  1092  for capturing a first visual field  1088 . 
     Some embodiments include a first camera unit  1082  (such as one of the cameras described below with respect to  FIG. 1B  and  FIG. 1C ) of a multifunction device capturing a first image of a first visual field  1086 .

In some embodiments, the first camera unit  1082  includes a first optical package with a first focal length  1090 . In some embodiments, the second camera unit  1084  includes a second optical package (described below with respect to  FIG. 1B , below) with a second focal length  1092 .

In some embodiments, the first image and the second image are preserved to a storage medium as separate data structures. 
     In some embodiments, a camera system of a multifunction device  1080 , includes a first camera unit  1082  of the multifunction device for capturing a first image of a first visual field  1086 . In some embodiments, the first camera unit  1082  includes a first optical image stabilization actuator for moving a first optical package configured for a first focal length  1090 . The camera system further includes second camera  1084  unit of the multifunction device  1080  for simultaneously capturing a second image of a first visual field  1088 . In some embodiments, the second camera unit  1084  includes a second optical image stabilization actuator for moving a second optical package configured for a second focal length  1092 . In some embodiments, the first focal length  1090  is different from the second focal length  1092 . In some embodiments, the first focal length being different from the second focal length includes both the first focal length and the second focal length being adjustable ranges, which may or may not overlap. 
     Some embodiments assign metadata to the first image of the first visual field  1086  and the second image of the first visual field  1088  a time indexing feature for establishing that the first image of the first visual field  1086  and the second image of the first visual field  1088  correspond as having been simultaneously captured. Some embodiments display the first image of the first visual field  1086  in a screen interface with a control for switching to display of the second image of the first visual field  1088 , and, responsive to an actuation of the control, display the second image of the first visual field  1088  in place of the first image. Some embodiments generate a synthetic intermediate image at least in part from data of the first image of the first visual field  1086  and data of the second image of the first visual field  1088 . In some embodiments, the synthetic intermediate image has a third focal length different from each of the first focal length  1090  and the second focal length  1092 , and the synthetic intermediate image has a third visual field different from each of the first visual field  1086  and the first visual field  1088 . Some embodiments preserve storage of the first image of the first visual field  1086  and data of the second image of the first visual field  1088  after creation of the synthetic intermediate image. 
     Some embodiments generate a synthetic result image at least in part from data of the first image of the first visual field  1086  and data of the second image of the first visual field  1088 . In some embodiments, the synthetic intermediate image has is generated by enhancing the first image of the first visual field  1086  using data from the second image of the first visual field  1088 . Some embodiments display the first image of the first visual field  1086  and the second image of the first visual field  1088  in a shared screen interface. 
     Some embodiments include a camera system of a multifunction device. In some embodiments, the camera system includes a first camera unit  1082  of a multifunction device  1080  for capturing a first image of a first visual field  1086  and a second camera unit of the multifunction device for simultaneously capturing a second image of a first visual field  1088 . In some embodiments, the first camera unit  1082  includes a first optical package configured for a first focal length  1090 . In some embodiments, the second camera unit  1084  includes a second optical package configured for a second focal length  1092 . In some embodiments, the first focal length  1090  is different from the second focal length  1092 . 
     In some embodiments, the camera system includes a processing unit configured to assign to the first image of a first visual field  1086  and the second image a time indexing feature for establishing that the first image and the second image of a first visual field  1088  were simultaneously captured. In some embodiments, the first camera unit  1082  includes a lens having a folded lens configuration (not shown) with a longer focal length  1090  than a focal length  1092  of a lens of the second camera unit  1084 , and the first visual field  1088  is centered on a second visual axis aligned with a first visual axis on which the first visual field  1086  is centered. In some embodiments, the first camera unit  1082  includes a first moveable lens (shown below with respect to  FIG. 1C ) and a first image sensor attached a chassis of the camera unit, the second camera unit includes a lens and a second image sensor moveably attached a chassis of the second camera unit  1084 . 
     In some embodiments, the first camera unit  1082  includes a first moveable lens and a first image sensor attached a chassis of the first  1082  camera unit, and the second camera unit  1084  includes a lens (shown below with respect to  FIG. 1C ) and a second image sensor moveably attached a chassis of the second camera unit. In some embodiments, the first camera unit  1082  and the second camera unit  1084  include a first image processing pipeline and a second image processing pipeline, respectively. 
     In some embodiments, the first image and second image are of different media types. For example, in some embodiments, the first image is a moving image data structure captured at a first frame rate. In some embodiments, the second image is a moving image data structure captured at a second frame rate. In some embodiments, the second frame rate is faster than the first frame rate. In some embodiments, the first image is a still image taken at time t( 0 ), and the second image is a moving image data structure captured over a time interval including t( 0 ). 
     In some embodiments, the first image has a first resolution and the second image has a second resolution. An example of the use of a first image that is a moving image data structure at a first frame rate and a second image that is a moving image data structure at a second frame rate arises in that some embodiments include second camera module  1084  recording 720p (also known as 720 pixels of vertical resolution progressive scan) slow motion video at 240 frames per second while first camera module  1082  is capturing 4K (horizontal resolution on the order of 4,000 pixels) video at 30 frames per second. In some embodiments, the analog-to-digital converter bandwidth required for each separate module to achieve the recording is 220-270 Mpixels/s. Achieving the same functionality with conventional single camera module technology requires up to 32 times higher analog-to-digital converter bandwidth for a single camera module if it is compared to embodiments in which there is a 2× difference in focal length from wide to tele module, providing benefits in terms of power, thermal dissipation, storage bandwidth, storage capacity, and actual achievable frame rates combined with zoom capability. 
     A use case for some embodiments is well-illustrated with respect to sports photography. In one example use case, it is possible to imagine a user of portable multifunction device  1080  filming a batter in a baseball game. Recording video of the game with portable multifunction device  1080  from bleachers, not shown, a user may decide to zoom in to capture a batter swinging and hitting the ball in slow motion using second camera module  1084  recording 720p slow motion video at 240 frames per second, but may subsequently want to switch to the simultaneously captured 4K video from first camera module  1082  at 30 frames per second of resulting home run in high quality video of the full baseball field, to capture the moments where the opposing team scrambles to catch the ball and the batter is running from base to base. Some embodiments enable this mixed-video capture by simultaneously recording using second camera module  1084  as a telephoto camera module in a 240 frames per second slow motion mode while at the same time using first camera module  1082  as a wide camera module in a 4K at 30 frames per second. After capturing a data structure including both video streams the awesome moment, some embodiments provide for a mixed-video data structure and an interface for the video streams from the two separate camera modules to be manually or automatically edited and combined to create a more engaging media which may contain normal 1080p video, 4K high resolution video, 720p motion video, and still images. In the example described above, this mixed-video media both captures the close up expressions of players, the peak action in slow motion, and frames it all in the context of a great play in a baseball game. 
     Another example of a use case for some embodiments arises in the context of capturing a child extinguishing candles on a birthday cake. In such an example, one can imagine a child about to blow out the candles on the birthday cake while all her friends are singing a birthday song. In some embodiments, second camera module  1084  can be used as a telephoto camera module to zoom in on the face of the child as she is about to blow out the candles and first camera module  1082  can capture a burst of high resolution still images of her smiling face. In some embodiments, first camera module  1082  is simultaneously capturing standard 1080p 30 frames per second video of the entire group of kids gathered and singing around the cake. Some embodiments provide an editing interface for combining the video stream from the wide camera module, either manually or automatically, with the close up portraits to create a much more engaging media experience which can be shared. As the two camera modules are synchronized in time, the still images can easily be automatically inserted at the right time in a final video stream. 
       FIG. 1B  illustrates a user interface for a multiple camera system for portable zoom, according to at least some embodiments. A portable multifunction device  100  displays a first image of a first visual field  104  captured by a first camera unit and a second image of a second visual field  102  simultaneously captured by a second camera unit of the multifunction device  100 . A zoom control  106  is displayed within first image of a first visual field  104 . In the embodiment shown, zoom control  106  is an area of first image of first visual field  104 , that, in response to control actuation through the touch screen of portable multifunction device  100 , is used as a control for toggling the display mode for displaying first image of a first visual field  104  captured by a first camera unit and second image of a second visual field  102  simultaneously captured by a second camera unit of the multifunction device  100 . 
     Some embodiments assign metadata to the first image  104  and the second image  102  for a time indexing feature for establishing that the first image  104  and the second image  102  correspond as having been simultaneously captured. Some embodiments display the first image  104  in a screen interface with a control (e.g., similar to control  106 ) for switching to display of the second image  102 , and, responsive to an actuation of the control  106 , display the second image  102  in place of the first image  104 . Some embodiments generate a synthetic intermediate image at least in part from data of the first image  104  and data of the second image  102 . 
       FIG. 1C  depicts a side view of an example embodiment of camera module, according to at least some embodiments. Camera module  1000 , which is an embodiment of cameras  1564   a - b  discussed below, includes camera components such as an optics module (e.g., a lens barrel)  1002  attached to an optics holder  1003  and a magnet holder  1006 . An image sensor  1070 , which may or may not be mounted on a substrate that is not shown separately in  FIG. 1C , is attached to a camera module base  1008 . The camera components may further include, in addition to components such as power and remote control connections not shown, a cover  1012  and suspension wires  1020 . 
     Optics module  1002  may be suspended on the base assembly  1008  by suspension of the upper springs  1030  and the suspension wires  1020 . Camera components may include one or more of, but are not limited to, optics  1002 , optics holder  1003 , magnet holder(s)  1006 , upper spring(s)  1030 , and lower spring(s)  1032 . The upper and lower spring(s) may be collectively referred to herein as optics springs. An optics module (e.g., a lens or lens assembly or lens barrel)  1002  may be screwed, mounted or otherwise held in or by an optics holder  1003 . In at least some embodiments, the optics  1002 /optics holder  1003  assembly may be suspended from or attached to the magnet holder  1006  by upper spring(s)  1030 , and lower spring(s)  1032 . Note that upper spring(s)  1030  and lower spring(s)  1032  are flexible to allow the optics assembly  1000  a range of motion along the Z (optical) axis for optical focusing, wires  1020  are flexible to allow a range of motion on the XY plane orthogonal to the optical axis for optical image stabilization. 
     Note that, in some embodiments, a camera may not include magnets and magnet holder(s)  1006 , but may include a yoke or other structure  1006  that may be used to help support the optics assembly on suspension wires  1020  via upper springs  1030 . In general, other embodiments of an optics assembly  1000  may include fewer or more components than the example optics assembly  1000  shown in  FIG. 1C . Also note that, while embodiments show the optics assembly  1000  suspended on wires  1020 , other mechanisms may be used to suspend an optics assembly  1000  in other embodiments. 
     The autofocus yoke (e.g., magnet holder(s)  1006 ) acts as the support chassis structure for the autofocus mechanism of actuator  1000 . The lens carrier (optics holder  1003 ) is suspended on the autofocus yoke by an upper autofocus (AF) spring  1030  and a lower optics spring  1032 . In this way when an electric current is applied to the autofocus coil, Lorentz forces are developed due to the presence of the four magnets, and a force substantially parallel to the optical axis is generated to move the lens carrier, and hence lens, along the optical axis, relative to the support structure of the autofocus mechanism of the actuator, so as to focus the lens. In addition to suspending the lens carrier and substantially eliminating parasitic motions, the upper spring  1030  and lower spring  1032  also resist the Lorentz forces, and hence convert the forces to a displacement of the lens. This basic architecture shown in  FIG. 1C  is typical of some embodiments, in which optical image stabilization function includes moving the entire autofocus mechanism of the actuator (supported by the autofocus yoke) in linear directions orthogonal to the optical axis, in response to user handshake, as detected by some means, such a two or three axis gyroscope, which senses angular velocity. The handshake of interest is the changing angular tilt of the camera in ‘pitch and yaw directions’, which can be compensated by said linear movements of the lens relative to the image sensor. 
     In at least some embodiments, the suspension of the autofocus mechanism on the actuator  1000  support structure may be achieved by the use of four corner wires  1020 , for example wires with a circular cross-section. Each wire  1020  acts as a flexure beams capable of bending with relatively low stiffness, thus allowing motion in both optical image stabilization degrees-of-freedom. However, wire  1020  is in some embodiments relatively stiff in directions parallel to the optical axis, as this would require the wire to stretch or buckle, thus substantially preventing parasitic motions in these directions. In addition, the presence of four such wires, appropriately separated allows them to be stiff in the parasitic tilt directions of pitch and yaw, thus substantially preventing relative dynamic tilt between the lens and image sensor. This may be seen by appreciating that each wire  1020  is stiff in directions that require it to change in length, and hence the fixed points at the ends of each wire (eight points in total) will substantially form the vertices of a parallelepiped for all operational positions of the optical image stabilization mechanism. 
       FIGS. 2A-D  illustrate an example embodiment of camera module components including paired side magnet arrays usable for a multiple camera system for portable zoom, according to at least some embodiments. 
     Each of  FIGS. 2A-2C  includes a different view of a camera unit  200   a - c , which is one embodiment of a first camera unit or a second camera unit of a multifunction device for capturing a first image of a first or second visual field.

Additionally, in some embodiments, lower magnet arrays  220   b - c  and upper magnet array  222   b  are arranged in analogous opposing and mutually-cancelling pairs. In some embodiments, the designation of central magnet arrays  206   a - c  and distal magnet arrays  218   a - c  is arbitrary, with the difference between them being the opposite and mutually cancelling arrangement of magnets in the respective arrays. In some embodiments, the designation of central magnet arrays  206   a - c  and distal magnet arrays  218   a - c  is defined with respect to a center line between a pair of camera units in a camera system, as described elsewhere herein. In some embodiments, an optical package or optics module is a set of components (e.g., a lens barrel) housing one or more lens elements and other components for connecting a lens to an actuator for moving the lens relative to an image sensor. 
     As portrayed in  FIGS. 2A-2D , camera units  200   a - c  include central magnet arrays  206   a - c , which can be situated along the axis between the optics package of a first camera unit and an optics package of a second camera unit.

Distal magnet array  218   a  includes a distal lower magnet  216   a  having the first polarity and a distal upper magnet  214   a  having the polarity antiparallel to the first polarity. 
     In some embodiments, camera units  200   a - c  include distal magnet arrays  218   a - c  that are situated opposite the central magnet arrays  206   a - c  with respect to the optics packages  202   a - c  of the camera units  200   a - c  and the distal magnet arrays  218   a - c  include a distal lower magnet  216   a  having the first polarity and a distal upper magnet  214   a  having the polarity antiparallel to the first polarity. 
     In some embodiments, camera units  200   a - c  include upper autofocus coils  208   a - b  and lower autofocus coils  228   a  attached to optics packages  202   a - c  for moving optics packages  202   a - c  in any of an X, Y, or Z axis, where, in some embodiments, the Z axis is the optical axis of optics packages  202   a - c  (thus, with at three degrees of freedom). In some embodiments, central magnet arrays  206   a - c  and distal magnet arrays  218   a - c  interact with upper latitudinal SP coils  226   a - c  and lower SP latitudinal coils  224   a  and  224   c.

       FIG. 3  depicts an example embodiment of camera modules including corner magnets in a shared magnet holder usable for a multiple camera system for portable zoom, according to at least some embodiments. 
     In some embodiments, the VCM applies the same OIS correction to both modules together at any given time. In some embodiments, OIS correction is a function of focal length and is different for the two modules. Thus, at any given moment the VCM can stabilize only one module. 
     In some embodiments, video capture involves shooting with only one lens at a time and the VCM can successfully command OIS correction as user switches between the 1× and 4× lenses. 
     In some embodiments, image fusion combines the wide field of view from a 1× lens and the narrow focus from a 4× lens to produce a wide angle image with extra detail and sharpness around the subject (image center). It can also be used to generate depth data (stereo vision). In some embodiments, dual OIS solution allows commanding different corrections on the two OIS modules simultaneously. In some embodiments, in fast exposure and shots with low subject motion, the two OIS corrections can be applied in succession producing the same effect.

     The first camera unit  1202   a  may include a first voice coil motor (VCM) actuator configured to move a first optical package (e.g., the first optical packages  1206   b ,  1206   c  illustrated in  FIGS. 12B-12C ). For instance, the first VCM actuator may be configured to move the first optical package along a first optical axis and/or along a first plane that is orthogonal to the first optical axis. The first optical package may include one or more lenses that define the first optical axis. 
     In various examples, the first VCM actuator of the first camera unit  1202   a  may include one or more magnets and/or one or more coils for actuation along the first optical axis and/or along the first plane that is orthogonal to the first optical axis.

     In some embodiments, the first VCM actuator of the first camera unit  1202   a  may include a symmetric magnet arrangement. For example, the first camera unit may be rectangular in plan, and the symmetric magnet arrangement may include multiple magnets that are individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   a .

     In some examples, the first VCM actuator may include a first magnet  1206   a , a second magnet  1208   a , a third magnet  1210   a , and a fourth magnet  1212   a . The magnets  1206   a - 1212   a  may form the symmetric magnet arrangement. The first camera unit  1202   a  may be rectangular in plan, and the magnets  1206   a - 1212   a  may be individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   a . For instance, in some embodiments, the magnets  1206   a - 1212   a  may be individually arranged to exhibit mirror symmetry about a respective plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   a . As illustrated in  FIG. 12A , the magnets  1206   a - 1212   a  may be corner magnets. That is, the magnets  1206   a - 1212   a  may be individually disposed proximate a respective corner of the first camera unit  1202   a.    
     In some embodiments, the first VCM actuator of the first camera unit  1202   a  may include a symmetric optical image stabilization coil arrangement for actuation along the first plane that is orthogonal to the first optical axis. For example, the first camera unit  1202   a  may be rectangular in plan, and the symmetric optical image stabilization coil arrangement may include multiple optical image stabilization coils that are individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   a . In some examples, the symmetric optical image stabilization coil arrangement may include four optical image stabilization coils that are individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   a . For instance, in some embodiments, the coils may be individually arranged to exhibit mirror symmetry about a respective plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   a.    
     In some examples, the first VCM actuator may include a first optical image stabilization coil  1214   a , a second optical image stabilization coil  1216   a , a third optical image stabilization coil  1218   a , and a fourth optical image stabilization coil  1220   a . The optical image stabilization coils  1214   a - 1220   a  may form the symmetric optical image stabilization coil arrangement. The first camera unit  1202   a  may be rectangular in plan, and the optical image stabilization coils  1214   a - 1220   a  may be individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   a . For instance, in some embodiments, the optical image stabilization coils  1214   a - 1220   a  may be individually arranged to exhibit mirror symmetry about a respective plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   a . As illustrated in  FIG. 12A , the optical image stabilization coils  1214   a - 1220   a  may be corner optical image stabilization coils. That is, the optical image stabilization coils  1214   a - 1220   a  may be individually disposed proximate a respective corner of the first camera unit  1202   a.    
     In some embodiments, at least one magnet of the symmetric magnet arrangement may be configured to magnetically interact with a corresponding optical image stabilization coil of the symmetric optical image stabilization coil arrangement. According to some examples, the first camera unit may be rectangular in plan, and a combined arrangement of the magnet and the corresponding optical image stabilization coil may exhibit mirror symmetry about a plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   a . For instance, in some embodiments, the combined arrangement of the magnet and the corresponding optical image stabilization coil may exhibit mirror symmetry about a plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   a.    
     As a non-limiting example, the first magnet  1206   a  may be configured to magnetically interact with the first optical image stabilization coil  1214   a . The combined arrangement of the first magnet  1206   a  and the first optical image stabilization coil  1214   a  may exhibit mirror symmetry about a plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   a . Similarly, the combined arrangement of the second magnet  1208   a  and a corresponding optical image stabilization coil (e.g., the second optical image stabilization coil  1216   a ), the combined arrangement of the third magnet  1210   a  and a corresponding optical image stabilization coil (e.g., the third optical image stabilization coil  1218   a ), and/or the combined arrangement of the fourth magnet  1212   a  and a corresponding optical image stabilization coil (e.g., the fourth optical image stabilization coil  1220   a ) may each exhibit mirror symmetry about a plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   a.    
     In various embodiments, the first VCM actuator of the first camera unit  1202   a  may include at least one autofocus coil  1222   a  for actuation along the first optical axis. For instance, the autofocus coil  1222   a  may be configured to radially surround the first optical package of the first camera unit  1202   a . In some embodiments, the autofocus coil  1222   a  may be octagonal in plan. Some or all of the magnets  1206   a - 1212   a  of the first VCM actuator may be individually disposed proximate a respective side of the octagonal autofocus coil  1222   a . However, it should be understood that in other embodiments the autofocus coil may otherwise be polygonal, or circular, in plan. 
     In some embodiments, the second camera unit  1204   a  may include a second VCM actuator configured to move a second optical package (e.g., the second optical packages  1226   b ,  1224   c  illustrated in  FIGS. 12B-C ). For instance, the second VCM actuator may be configured to move the first optical package along a first optical axis and/or along a first plane that is orthogonal to the first optical axis. The first optical package may include one or more lenses that define the first optical axis. 
     In some embodiments, the second VCM actuator of the second camera unit  1204   a  may include one or more magnets and/or one or more coils for actuation along the second optical axis and/or along the second plane that is orthogonal to the second optical axis. For instance, at least one of the coils may be configured to receive a current that causes the coil to produce a magnetic field that interacts with at least one magnetic field of the one or more magnets. 
     In some embodiments, the second VCM actuator of the second camera unit  1204   a  may include an asymmetric magnet arrangement. For example, the second camera unit  1204   a  may be rectangular in plan, and the asymmetric magnet arrangement may include a first magnet  1224   a  (e.g., an actuator lateral magnet) disposed proximate a first side of the second camera unit  1204   a , a second magnet  1226   a  (e.g., an actuator transverse magnet) disposed proximate a second side of the second camera unit  1204   a , and a third magnet  1228   a  (e.g., an actuator transverse magnet) disposed proximate a third side of the second camera unit  1204   a . The third side of the second camera unit  1204   a  may be opposite the second side of the second camera unit  1204   a . In some embodiments, no magnets are disposed proximate a fourth side of the second camera unit  1204   a . The fourth side of the second camera unit  1204   a  may be opposite the first side of the second camera unit  1204   a.    
     In some examples, the second VCM actuator of the second camera unit  1204   a  may include an asymmetric optical image stabilization coil arrangement for actuation along the second plane that is orthogonal to the second optical axis. For example, the asymmetric optical image stabilization coil arrangement may include a first optical image stabilization coil  1230   a  disposed proximate to the first magnet  1224   a  of the asymmetric magnet arrangement, a second optical image stabilization coil  1232   a  disposed proximate to the second magnet  1226   a  of the asymmetric magnet arrangement, and a third optical image stabilization coil  1234   a  disposed proximate the third magnet  1228   a  of the asymmetric magnet arrangement. 
     In various embodiments, the second VCM actuator of the second camera unit  1202   a  may include one or more autofocus coils for actuation along the second optical axis. For instance, the autofocus coils of the second VCM actuator may include a first autofocus coil  1236   a  disposed proximate the second magnet  1226   a  of the asymmetric magnet arrangement, and a second autofocus coil  1238   a  disposed proximate the third magnet  1228   a  of the asymmetric magnet arrangement. 
     In some embodiments, the first camera unit  1202   a  may be disposed adjacent to the second camera unit  1204   a . For example, the first camera unit  1202   a  and the second camera unit  1204   a  may each be rectangular in plan, and the first camera unit  1202   a  may be disposed adjacent to the second camera unit  1204   a  along a first axis that intersects a second axis. For instance, the second axis may extend through the first optical package of the first camera unit  1202   a  and the second optical package of the second camera unit  1204   a . The asymmetric magnet arrangement of the second VCM actuator may include a first magnet  1224   a  disposed proximate a first side of the second camera unit  1204   a  that is distal to the first axis. Furthermore, the first magnet  1224   a  may have a longitudinal axis that is parallel to the first axis. In some embodiments, no magnets are disposed proximate a second side of the second camera unit  1204   a  that is opposite the first side of the second camera unit  1204   a . The second side of the second camera unit  1204   a  may extend in a direction that is parallel to the first axis. In some examples, a dummy mass (e.g., the dummy mass  1240   c  illustrated in  FIG. 12C ) may be disposed proximate the second side of the second camera unit  1204   a  that is opposite the first side of the second camera unit. The dummy mass may be configured to act as a counterbalance to the first magnet  1224   a  disposed proximate the first side of the second camera unit  1204   a.    
     In some examples, the first camera unit  1202   a  may be smaller in one or more dimensions than the second camera unit  1204   a . For example, the corner magnet and coil arrangement of the first VCM actuator may allow for a smaller X, Y, and/or Z dimension of the first camera unit  1202   a  than a corresponding X, Y, and/or Z dimension of the second camera unit  1204   a . For instance, the broken line illustrated in  FIG. 12A  includes a tapered portion  1240   a  that indicates a difference in size between the first camera unit  1202   a  and the second camera unit  1204   a.    
     In some embodiments, the first camera unit  1202   a  may be configured to capture a first image of a first visual field. The second camera unit  1204   a  may be configured to capture a second image of a second visual field. In some examples, the first camera unit  1202   a  and the second camera unit  1204   a  may be configured to simultaneously capture the first image of the first visual field and the second image of the second visual field, respectively. The second visual field may be a subset of the first visual field. Furthermore, in some embodiments, the first optical package of the first camera unit  1202   a  may be configured for a first focal length, and the second optical package of the second camera unit  1204   a  may be configured for a second focal length. The second focal length may be a different length than the first focal length. In some examples, the first optical package of the first camera unit  1202   a  may be configured with a wide-angle lens and the second optical package of the second camera unit  1204   a  may be configured with a telephoto lens. 
     In some embodiments, the first camera unit  1202   a  and the second camera unit  1204   a  may include any suitable component, arrangement, architecture, and/or functionality disclosed herein. In some non-limiting examples, the first VCM actuator and/or the first camera unit  1202   a  may be configured, and/or function, similar to one or more of the camera modules that include a symmetric magnet arrangement (e.g., a corner magnet arrangement) discussed above, e.g., with reference to  FIG. 3 . In some non-limiting examples, the second VCM actuator and/or the second camera unit  1204   a  may be configured, and/or function, similar to one or more of the camera modules that include an asymmetric magnet arrangement discussed above, e.g., with reference to  FIGS. 10A-10B . Additionally or alternatively, the first camera unit  1202   a  and/or the second camera unit  1204   a  may include an architecture similar to one or more of the architectures discussed above, e.g., with reference to  FIG. 1C . 
     In some embodiments, the autofocus coil  1222   a  of the first VCM actuator may be attached to the first optical package of the first camera unit  1202   a . A yoke component (not shown) of the first camera unit  1202   a  may support and house the four magnets  1206   a - 1212   a  of the first VCM actuator. Each of the magnets  1206   a - 1212   a  may be poled so as to generate a magnetic field, the useful component of which for the autofocus function is orthogonal to the first optical axis. The magnetic field for all four magnets may all either be directed towards the autofocus coil  1222   a , or away from the autofocus coil  1222   a , so that the Lorentz forces from all four magnets act in the same direction along the first optical axis, thereby causing the autofocus coil  1222   a  and the first optical package to move along the first optical axis. The yoke component may act as a support chassis structure for the autofocus mechanism of the first VCM actuator. The first optical package may be suspended on the yoke component by an upper spring (e.g., the upper spring  1030  illustrated in  FIG. 1C ) and a lower spring (e.g., the lower spring  1032  illustrated in  FIG. 1C ). In this way when an electric current is applied to autofocus coil  1222   a , Lorentz forces are developed due to the presence of the four magnets  1206   a - 1220   a , and a force substantially parallel to the first optical axis is generated to move the first optical package, and hence one or more lens elements within the first optical package, along the first optical package, relative to the yoke component so as to focus the lens. In addition to suspending the first optical package and substantially eliminating parasitic motions, the upper spring and lower spring may also resist the Lorentz forces, and hence convert the forces to a displacement of the lens. 
     In some embodiments, the suspension of the yoke component may be achieved by the use of four corner wires (e.g., the suspension wires  1020  illustrated in  FIG. 1C ), for instance, wires with a circular cross-section. Each wire may act as a flexure beam capable of bending with relatively low stiffness, thus allowing motion in both optical image stabilization degrees-of-freedom. In some embodiments, the wires may be relatively stiff in directions parallel to the optical axis, as this would require the wire to stretch or buckle, thus substantially preventing parasitic motions in these directions. Furthermore, the presence of four such wires, appropriately separated allows them to be stiff in the parasitic tilt directions of pitch and yaw, thus substantially preventing relative dynamic tilt between the lens and image sensor. 
     Embodiments may achieve two independent degree-of-freedom motion, orthogonal to the first optical axis, by using the optical image stabilization coils  1214   a - 1220   a . In some cases, a first pair of the optical image stabilization coils  1214   a - 1220   a  may act together to deliver controlled motion in one linear axis orthogonal to the first optical axis, and a second pair may deliver controlled motion in a direction substantially orthogonal to the first pair. The optical image stabilization coils  1214   a - 1220   a  may be fixed to a base component (e.g., the base  1008  illustrated in  FIG. 1C ) of the first camera unit  1202   a , and when current is appropriately applied, the optical image stabilization coils  1214   a - 1220   a  may interact with the magnets  1206   a - 1212   a  to generate Lorentz forces that move the first optical package as desired along one or more directions orthogonal to the first optical axis. 
     In various embodiments, the first camera unit  1202   a  may include an image sensor (e.g., the image sensor  1070  illustrated in  FIG. 1C ). The image sensor may be disposed below the first optical package such that light rays may pass through one or more lens elements of the first optical package (e.g., via an aperture at the top of the first optical package) and to the image sensor. 
     In some embodiments, the autofocus coils  1236   a - 1238   a  of the second VCM actuator may be attached to opposing sides, or opposing portions, of the second optical package of the second camera unit  1204   a . A yoke component (not shown) of the first camera unit  1202   a  may support and house the magnets  1224   a - 1228   a  of the second VCM actuator. In some examples, the second magnet  1226   a  and the third magnet  1228   a  may each be dual pole magnets that interact with the autofocus coils  1236   a - 1238   a . Each of the dual pole magnets may include opposing polarities, as discussed above with reference to  FIGS. 10A-11B  and as discussed below with reference to  FIG. 12C . The second magnet  1226   a  may be a dual pole magnet that interacts with the first autofocus coil  1236   a , and the third magnet  1228   a  may be a dual pole magnet that interacts with the second autofocus coil  1238   a . The interaction between the dual pole magnets  1226   a - 1228   a  and the autofocus coils  1236   a - 1238   a  may generate forces that move the optical package along the second optical axis for optical focusing. 
     The second VCM actuator may include four suspension wires (e.g., the wires  1020   a  illustrated in  FIG. 1C ). The second optical package may be suspended with respect to a base structure (e.g., the base  1008  illustrated in  FIG. 1C ) by suspending one or more upper springs (e.g., the upper springs  1030  illustrated in  FIG. 1C ) on the suspension wires. In some embodiments, the second VCM actuator may include one or more lower springs (e.g., the lower springs  1032  illustrated in  FIG. 1C ). The upper spring(s) and the lower spring(s) may be flexible to allow the second optical package a range of motion along the second optical axis for optical focusing, and the suspension wires may be flexible to allow a range of motion on one or more directions orthogonal to the optical axis for optical image stabilization. 
     Embodiments may achieve two independent degree-of-freedom motion, orthogonal to the second optical axis, by using the optical image stabilization coils  1230   a - 1234   a . The optical image stabilization coils  1230   a - 1234   a  may be fixed to a base component (e.g., the base  1008  illustrated in  FIG. 1C ) of the second camera unit  1204   a , and when current is appropriately applied, the optical image stabilization coils  1214   a - 1220   a  may interact with the magnets  1206   a - 1212   a  to generate Lorentz forces that move the first optical package as desired along one or more directions orthogonal to the first optical axis. In some cases, a first pair of optical image stabilization coils  1232   a - 1234   a  may interact with the pair of dual pole magnets  1226   a - 1228   a  to deliver controlled motion in a first direction orthogonal to the second optical axis. The first optical image stabilization coil  1230   a  may interact with the first magnet  1224   a , which may be a single pole magnet, to deliver controlled motion in a second direction orthogonal to the second optical axis and the first direction. 
     In various embodiments, the second camera unit  1204   a  may include an image sensor (e.g., the image sensor  1070  illustrated in  FIG. 1C ). The image sensor may be disposed below the second optical package such that light rays may pass through one or more lens elements of the second optical package (e.g., via an aperture at the top of the second optical package) and to the image sensor.

     In some embodiments, the first VCM actuator of the first camera unit  1202   b  may include a symmetric optical image stabilization coil arrangement for actuation along the first plane that is orthogonal to the first optical axis. For example, the first camera unit  1202   b  may be rectangular in plan, and the symmetric optical image stabilization coil arrangement may include multiple optical image stabilization coils that are individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   b .

     In various embodiments, the first VCM actuator of the first camera unit  1202   b  may include at least one autofocus coil  1224   b  for actuation along the first optical axis. For instance, the autofocus coil  1224   b  may be configured to radially surround the first optical package  1206   b  of the first camera unit  1202   b . In some embodiments, the autofocus coil  1224   b  may be octagonal in plan. However, it should be understood that in other embodiments the autofocus coil  1224   b  may otherwise be polygonal, or circular, in plan. 
     The second camera unit  1204   b  may include a second VCM actuator configured to move a second optical package  1226   b . For instance, the second VCM actuator may be configured to move the second optical package  1226   b  along a second optical axis and/or along a second plane that is orthogonal to the second optical axis.

In some examples, the third optical image stabilization coil  1232   b  may be a racetrack coil with a longitudinal axis that is substantially parallel to the third side  1238   b  of the second camera unit  1204   b.    
     In some embodiments, no coils are disposed proximate a fourth side  1240   b  of the second camera unit  1204   b . The fourth side  1240   b  of the second camera unit  1204   b  may be opposite the first side  1234   b  of the second camera unit  1204   b.    
     In various embodiments, the second VCM actuator of the second camera unit  1204   b  may include one or more autofocus coils for actuation along the second optical axis. For instance, the autofocus coils of the second VCM actuator may include a first autofocus coil  1242   b  and a second autofocus coil  1244   b . The first autofocus coil  1242   b  may be disposed proximate the second optical image stabilization coil  1230   b . Additionally or alternatively, the first autofocus coil  1242   b  may be situated to a first side of the second optical package  1226   b . In some examples, the first autofocus coil  1242   b  may be racetrack coil with a longitudinal axis that is substantially parallel to the second side  1236   b  of the second camera unit  1204   b . In some embodiments, the first autofocus coil  1242   b  may have a lateral axis that is substantially perpendicular to a lateral axis of the second optical image stabilization coil  1230   b . Likewise, the second autofocus coil  1244   b  may have a lateral axis that is substantially perpendicular to a lateral axis of the third optical image stabilization coil  1232   b . Furthermore, the first autofocus coil  1242   b  may have a longitudinal axis that is substantially parallel to a longitudinal axis of the second optical image stabilization coil  1230   b . Similarly, the second autofocus coil  1244   b  may have a longitudinal axis that is substantially parallel to a longitudinal axis of the third optical image stabilization coil  1232   b.    
       FIG. 12C  depicts an example embodiment of a camera system  1200   c  including a first camera unit  1202   c  and a second camera unit  1204   c , according to some embodiments. In particular,  FIG. 12C  illustrates example magnet arrangements of the first camera unit  1202   c  and the second camera unit  1204   c . The first camera unit  1202   c  and the second camera unit  1204   c  may include coils (e.g., the example coil arrangements illustrated in  FIG. 12B ) configured to magnetically interact with magnets of the example magnet arrangements. 
     The first camera unit  1202   c  may include a first VCM actuator configured to move a first optical package  1206   c . For instance, the first VCM actuator may be configured to move the first optical package  1206   c  along a first optical axis and/or along a first plane that is orthogonal to the first optical axis. The first optical package  1206   c  may include one or more lenses that define the first optical axis. 
     In some embodiments, the first VCM actuator of the first camera unit  1202   c  may include a symmetric magnet arrangement. For example, the first camera unit may be rectangular in plan, and the symmetric magnet arrangement may include multiple magnets that are individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   c . In some examples, the symmetric magnet arrangement may include four magnets that are individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   c . For instance, in some embodiments, the magnets may be individually arranged to exhibit mirror symmetry about a respective plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   c.    
     In some examples, the first VCM actuator may include a first magnet  1208   c , a second magnet  1210   c , a third magnet  1212   c , and a fourth magnet  1214   c . The magnets  1208   c - 1214   c  may form the symmetric magnet arrangement. The first camera unit  1202   c  may be rectangular in plan, and the magnets  1208   c - 1214   c  may be individually arranged to exhibit mirror symmetry about a respective plane that is angled, at a non-zero angle, with respect to at least one side of the first camera unit  1202   c . For instance, in some embodiments, the magnets  1208   c - 1214   c  may be individually arranged to exhibit mirror symmetry about a respective plane that is angled at or about 45 degrees with respect to at least one side of the first camera unit  1202   c.    
     As illustrated in  FIG. 12C , the magnets  1208   c - 1214   c  may be corner magnets. That is, the magnets  1208   c - 1214   c  may be individually disposed proximate a respective corner of the first camera unit  1202   c . For example, the first magnet  1208   c  may be disposed proximate a first corner  1216   c  of the first camera unit  1202   c , the second magnet  1210   c  may be disposed proximate a second corner  1218   c  of the first camera unit  1202   c , the third magnet  1212   c  may be disposed proximate a third corner  1220   c  of the first camera unit  1202   c , and/or the fourth magnet  1214   c  may be disposed proximate a fourth corner  1222   c  of the first camera unit  1202   c.    
     In some embodiments, the first magnet  1208   c , the second magnet  1210   c , the third magnet  1212   c , and/or the fourth magnet  1214   c  may each be a single pole magnet. In other embodiments, the first magnet  1208   c , the second magnet  1210   c , the third magnet  1212   c , and/or the fourth magnet  1214   c  may each be a dual pole magnet. The arrows depicted in  FIG. 12C  indicate example polarity directions of the magnets. 
     The second camera unit  1204   c  may include a second VCM actuator configured to move a second optical package  1224   c . For instance, the second VCM actuator may be configured to move the second optical package  1224   c  along a second optical axis and/or along a second plane that is orthogonal to the second optical axis. The second optical package  1224   c  may include one or more lenses that define the second optical axis. 
     In some embodiments, the second VCM actuator of the second camera unit  1204   c  may include an asymmetric magnet arrangement. For example, the second camera unit  1204   c  may be rectangular in plan, and the asymmetric magnet arrangement may include a first magnet  1226   c  (e.g., an actuator lateral magnet) disposed proximate a first side  1228   c  of the second camera unit  1204   c , a second magnet  1230   c  (e.g., an actuator transverse magnet) disposed proximate a second side  1232   c  of the second camera unit  1204   a , and a third magnet  1234   c  (e.g., an actuator transverse magnet) disposed proximate a third side  1236   c  of the second camera unit  1204   c . The third side  1236   c  of the second camera unit  1204   c  may be opposite the second side  1232   c  of the second camera unit  1204   c.    
     In some embodiments, no magnets are disposed proximate a fourth side  1238   c  of the second camera unit  1204   c . The fourth side  1238   c  of the second camera unit  1204   c  may be opposite the first side  1228   c  of the second camera unit  1204   c . In various examples, a dummy mass  1240   c  may be disposed proximate the fourth side  1238   c  of the second camera unit  1204   c . The dummy mass  1240   c  may be configured to act as a counterbalance to the first magnet  1226   c  disposed proximate the first side  1228   c  of the second camera unit  1204   c.    
     In some embodiments, the first magnet  1226   c  may be a single pole magnet. Furthermore, the second magnet  1230   c  and the third magnet  1234   c  may each be a dual pole magnet. The arrows depicted in  FIG. 12C  indicate example polarity directions of the magnets. It should be understood, however, that the magnets may have polarity directions that are different than those illustrated in  FIG. 12C . Furthermore, in other embodiments, the first magnet  1226   c  may be a dual pole magnet, the second magnet  1230   c  may be a single pole magnet, and/or the third magnet  1234   c  may be a single pole magnet. 
     In some embodiments, the first camera unit  1202   c  may be disposed adjacent to the second camera unit  1204   c . For example, the first camera unit  1202   c  and the second camera unit  1204   c  may each be rectangular in plan, and the first camera unit  1202   c  may be disposed adjacent to the second camera unit  1204   c  along a first axis  1242   c  that intersects a second axis  1244   c . For instance, the second axis  1244   c  may extend through the first optical package  1206   c  of the first camera unit  1202   c  and the second optical package  1224   c  of the second camera unit  1204   c . In some instances, the second axis  1244   c  may be substantially perpendicular to the first axis  1242   c . The first side  1228   c  of the second camera unit  1228   c  may be distal to the first axis  1242   c . Furthermore, the first magnet  1226   c  may have a longitudinal axis that is substantially parallel to the first axis  1242   c . The fourth side  1238   c  may be proximal to the first axis  1242   c . Furthermore, dummy mass  1240   c  may have a longitudinal axis that is substantially parallel to the first axis  1242   c.    
     In some non-limiting examples, the first camera unit  1202   c  and the second camera unit  1204   c  may be configured such that magnetic interaction between the first camera unit  1202   c  and the second camera unit  1204   c  is mitigated. The first VCM actuator of the first camera unit  1202   c  may include one or more magnets that are disposed proximate the second VCM actuator of the second camera unit  1204   c . For instance, in some embodiments, the second magnet  1210   c  and the third magnet  1212   c  of the second VCM actuator of the first camera unit  1202   c  may be disposed proximate the second camera unit  1204   c , and thus may be considered as a first set of near magnets relative to the second camera unit  1204   c . Similarly, the second VCM actuator of the second camera unit  1204   c  may include one or more magnets that are disposed proximate the first VCM actuator of the first camera unit  1202   c . For instance, the second magnet  1230   c  and the third magnet  1234   c  of the second VCM actuator of the second camera unit  1204   c  may be disposed proximate the first camera unit  1202   c , and thus may be considered as a second set of near magnets relative to the first camera unit  1202   c.    
     In various embodiments, each magnet of the first set of near magnets of the first camera unit  1202   c  may be a single pole magnet, and each magnet of the second set of near magnets of the second camera unit  1204   c  may be a dual pole magnet. In some cases, such a configuration may mitigate magnetic interaction between the first camera unit  1202   c  and the second camera unit  1204   c . That is, by configuring the first camera unit  1202   c  and the second camera unit  1204   c  such that single pole magnets of the first camera unit  1202   c  and dual pole magnets of the second camera unit  1204   c  are nearest each other, the magnetic interaction between the camera units  1202   c  and  1204   c  may be mitigated relative to some other configurations (e.g, the example magnet arrangement  1300   a  illustrated in  FIG. 13A ). The mitigated magnetic interaction may be due to the particular shapes and extensions of the magnetic fields of the single pole magnets and the dual pole magnets, as discussed in further detail below with reference to  FIGS. 13A and 13B . 
       FIG. 13A  depicts an example magnet arrangement that includes a first single pole magnet adjacent to a second single pole magnet.  FIG. 13B  depicts an example magnet arrangement that includes a single pole magnet adjacent to a dual pole magnet.  FIGS. 13A and 13B  illustrate a difference in amount of magnetic interaction between the single pole-single pole magnet arrangement of  FIG. 13A  and the single pole-dual pole magnet arrangement of  FIG. 13B . In some examples, the single pole-dual pole magnet arrangement of  FIG. 13B  is illustrative of mitigated magnetic interaction between the first camera unit  1202   c  and the second camera unit  1204   c  described above with reference to  FIG. 12C . 
     As illustrated in  FIG. 13A , the example magnet arrangement  1300   a  includes a first single pole magnet  1302   a  and a second single pole magnet  1304   a . The first single pole magnet  1302   a  is adjacent to the second single pole magnet  1304   a . The first single pole magnet  1302   a  may have a first magnetic field  1306   a . The second single pole magnet  1304   a  may have a second magnetic field  1308   a . The first magnetic field  1306   a  may extend away from the first single pole magnet  1302   a , and the second magnetic field  1308   a  may extend away from the second single pole magnet  1304   a . For example, the first magnetic field  1306   a  of the first single pole magnet  1306   a  may extend toward the second single pole magnet  1304   a  and the second magnetic field  1308   a  may extend toward the first single pole magnet  1302   a  such that the first magnetic field  1306   a  and the second magnetic field  1308   a  interact, as indicated by the overlapping magnetic field lines within the dashed line rectangle  1310   a.    
     As illustrated in  FIG. 13B , the example magnet arrangement  1300   b  includes a single pole magnet  1302   b  and a dual pole magnet  1304   b . The single pole magnet  1302   b  is adjacent to the dual pole magnet  1304   b . The single pole magnet  1302   b  may have a first magnetic field  1306   b . The dual pole magnet  1304   b  may have a second magnetic field  1308   b . Due to the respective polarity configurations of the single pole magnet  1302   b  and the dual pole magnet  1304   b , the first magnetic field  1306   b  may extend away from the single pole magnet  1302   b  to a greater extent than the second magnetic field  1308   b  extends away from dual pole magnet  1304   b . The tightness of the extension of the second magnetic field  1308   b  with respect to the dual pole magnet  1304   b  may mitigate interaction between the second magnetic field  1308   b  of the dual pole magnet  1304   b  and the first magnetic field  1306   b  of the single pole magnet  1302   b , e.g., as indicated by the magnetic field lines not overlapping within the dashed line rectangle  1310   b . In some examples, the single pole-dual pole magnet arrangement of  FIG. 13B  is illustrative of mitigated magnetic interaction between the first camera unit  1202   c  and the second camera unit  1204   c  described above with reference to  FIG. 12C .

Audio circuitry  1510  converts the electrical signal to audio data and transmits the audio data to peripherals interface  1518  for processing. Audio data may be retrieved from and/or transmitted to memory  1502  and/or RF circuitry  1508  by peripherals interface  1518 . In some embodiments, audio circuitry  1510  also includes a headset jack (e.g.,  1612 ,  FIG. 16 ). The headset jack provides an interface between audio circuitry  1510  and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone). 
     I/O subsystem  1506  couples input/output peripherals on device  1500 , such as touch screen  1512  and other input control devices  1516 , to peripherals interface  1518 . I/O subsystem  1506  may include display controller  1556  and one or more input controllers  1560  for other input or control devices. The one or more input controllers  1560  receive/send electrical signals from/to other input or control devices  1516 . The other input control devices  1516  may include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s)  1560  may be coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse.

The one or more buttons may include a push button (e.g.,  1606 ,  FIG. 16 ). 
     Touch-sensitive display  1512  provides an input interface and an output interface between the device and a user. Display controller  1556  receives and/or sends electrical signals from/to touch screen  1512 . Touch screen  1512  displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects. 
     Touch screen  1512  has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen  1512  and display controller  1556  (along with any associated modules and/or sets of instructions in memory  1502 ) detect contact (and any movement or breaking of the contact) on touch screen  1512  and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen  1512 . In an example embodiment, a point of contact between touch screen  1512  and the user corresponds to a finger of the user. 
     Touch screen  1512  may use LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. Touch screen  1512  and display controller  1556  may detect contact and any movement or breaking thereof using any of a variety of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen  1512 . In an example embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif. 
     Touch screen  1512  may have a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user may make contact with touch screen  1512  using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions calculated by the user. 
     In some embodiments, in addition to the touch screen, device  1500  may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from touch screen  1512  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  1500  also includes power system  1562  for powering the various components. Power system  1562  may include a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices. 
     Device  1500  may also include optical sensors or cameras  1564   a - b . Optical sensors  1564   a - b  may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensors  1564   a - b  receive light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module  1543  (also called a camera module), optical sensors  1564   a - b  may capture still images or video. In some embodiments, an optical sensor is located on the back of device  1500 , opposite touch screen display  1512  on the front of the device, so that the touch screen display may be used as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user&#39;s image may be obtained for videoconferencing while the user views the other video conference participants on the touch screen display. In embodiments in which multiple cameras or optical sensors  1564   a - b  are supported, each of the multiple cameras or optical sensors  1564   a - b  may include its own photo sensor(s), or the multiple cameras or optical sensors  1564   a - b  may be supported by a shared photo sensor. Likewise, in embodiments in which multiple cameras or optical sensors  1564   a - b  are supported, each of the multiple cameras or optical sensors  1564   a - b  may include its own image processing pipeline of processors and storage units, or the multiple cameras or optical sensors  1564   a - b  may be supported by an image processing pipeline of processors and storage units. 
     Device  1500  may also include one or more proximity sensors  1566 .  FIG. 15  shows proximity sensor  1566  coupled to peripherals interface  1518 . Alternately, proximity sensor  1566  may be coupled to input controller  1560  in I/O subsystem  1506 . In some embodiments, the proximity sensor turns off and disables touch screen  1512  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  1500  includes one or more orientation sensors  1568 . In some embodiments, the one or more orientation sensors include one or more accelerometers (e.g., one or more linear accelerometers and/or one or more rotational accelerometers). In some embodiments, the one or more orientation sensors include one or more gyroscopes. In some embodiments, the one or more orientation sensors include one or more magnetometers. In some embodiments, the one or more orientation sensors include one or more of global positioning system (GPS), Global Navigation Satellite System (GLONASS), and/or other global navigation system receivers. The GPS, GLONASS, and/or other global navigation system receivers may be used for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device  1500 . In some embodiments, the one or more orientation sensors include any combination of orientation/rotation sensors.  FIG. 15  shows the one or more orientation sensors  1568  coupled to peripherals interface  1518 . Alternately, the one or more orientation sensors  1568  may be coupled to an input controller  1560  in I/O subsystem  1506 . In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more orientation sensors. 
     In some embodiments, the software components stored in memory  1502  include operating system  1526 , communication module (or set of instructions)  1528 , contact/motion module (or set of instructions)  1530 , graphics module (or set of instructions)  1532 , text input module (or set of instructions)  1534 , Global Positioning System (GPS) module (or set of instructions)  1535 , arbiter module  1557  and applications (or sets of instructions)  1536 . Furthermore, in some embodiments memory  1502  stores device/global internal state  1557 . Device/global internal state  1557  includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display  1512 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  1516 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  1526  (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components. 
     Communication module  1528  facilitates communication with other devices over one or more external ports  1524  and also includes various software components for handling data received by RF circuitry  1508  and/or external port  1524 . External port  1524  (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices. 
     Contact/motion module  1530  may detect contact with touch screen  1512  (in conjunction with display controller  1556 ) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  1530  includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module  1530  receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module  1530  and display controller  1556  detect contact on a touchpad. 
     Contact/motion module  1530  may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event. 
     Graphics module  1532  includes various known software components for rendering and displaying graphics on touch screen  1512  or other display, including components for changing the intensity of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like. 
     In some embodiments, graphics module  1532  stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module  1532  receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller  1556 . 
     Text input module  1534 , which may be a component of graphics module  1532 , provides soft keyboards for entering text in various applications (e.g., contacts  1537 , e-mail  1540 , IM  1541 , browser  1547 , and any other application that needs text input). 
     GPS module  1535  determines the location of the device and provides this information for use in various applications (e.g., to telephone  1538  for use in location-based dialing, to camera  1543  as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).
