Description:
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 these 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.

     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.

     Audio circuitry  110 , speaker  111 , and microphone  113  provide an audio interface between a user and device  100 . Audio circuitry  110  receives audio data from peripherals interface  118 , converts the audio data to an electrical signal, and transmits the electrical signal to speaker  111 . Speaker  111  converts the electrical signal to human-audible sound waves. Audio circuitry  110  also receives electrical signals converted by microphone  113  from sound waves. Audio circuitry  110  converts the electrical signal to audio data and transmits the audio data to peripherals interface  118  for processing. Audio data may be retrieved from and/or transmitted to memory  102  and/or RF circuitry  108  by peripherals interface  118 . In some embodiments, audio circuitry  110  also includes a headset jack (e.g.,  212 ,  FIG. 2 ). The headset jack provides an interface between audio circuitry  110  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  106  couples input/output peripherals on device  100 , such as touch screen  112  and other input control devices  116 , to peripherals interface  118 . I/O subsystem  106  may include display controller  156  and one or more input controllers  160  for other input or control devices. The one or more input controllers  160  receive/send electrical signals from/to other input or control devices  116 . The other input control devices  116  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)  160  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 (e.g.,  208 ,  FIG. 2 ) may include an up/down button for volume control of speaker  111  and/or microphone  113 . The one or more buttons may include a push button (e.g.,  206 ,  FIG. 2 ). 
     Touch-sensitive display  112  provides an input interface and an output interface between the device and a user. Display controller  156  receives and/or sends electrical signals from/to touch screen  112 . Touch screen  112  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  112  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  112  and display controller  156  (along with any associated modules and/or sets of instructions in memory  102 ) detect contact (and any movement or breaking of the contact) on touch screen  112  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  112 . In an example embodiment, a point of contact between touch screen  112  and the user corresponds to a finger of the user. 
     Touch screen  112  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  112  and display controller  156  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  112 . 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  112  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  112  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  100  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  112  or an extension of the touch-sensitive surface formed by the touch screen. 
     Device  100  also includes power system  162  for powering the various components. Power system  162  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  100  may also include optical sensors or cameras  164   a - b . Optical sensors  164   a - b  may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensors  164   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  143  (also called a camera module), optical sensors  164   a - b  may capture still images or video. In some embodiments, an optical sensor is located on the back of device  100 , opposite touch screen display  112  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  164   a - b  are supported, each of the multiple cameras or optical sensors  164   a - b  may include its own photo sensor(s), or the multiple cameras or optical sensors  164   a - b  may be supported by a shared photo sensor. Likewise, in embodiments in which multiple cameras or optical sensors  164   a - b  are supported, each of the multiple cameras or optical sensors  164   a - b  may include its own image processing pipeline of processors and storage units, or the multiple cameras or optical sensors  164   a - b  may be supported by a image processing pipeline of processors and storage units.

Alternately, proximity sensor  166  may be coupled to input controller  160  in I/O subsystem  106 . In some embodiments, the proximity sensor turns off and disables touch screen  112  when the multifunction device is placed near the user&#39;s ear (e.g., when the user is making a phone call). 
     Device  100  includes one or more orientation sensors  168 . 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  100 . In some embodiments, the one or more orientation sensors include any combination of orientation/rotation sensors.  FIG. 1  shows the one or more orientation sensors  168  coupled to peripherals interface  118 . Alternately, the one or more orientation sensors  168  may be coupled to an input controller  160  in I/O subsystem  106 . 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  102  include operating system  126 , communication module (or set of instructions)  128 , contact/motion module (or set of instructions)  130 , graphics module (or set of instructions)  132 , text input module (or set of instructions)  134 , Global Positioning System (GPS) module (or set of instructions)  135 , arbiter module  157  and applications (or sets of instructions)  136 . Furthermore, in some embodiments memory  102  stores device/global internal state  157 , as shown in  FIGS. 1A and 3 . Device/global internal state  157  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  112 ; sensor state, including information obtained from the device&#39;s various sensors and input control devices  116 ; and location information concerning the device&#39;s location and/or attitude. 
     Operating system  126  (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  128  facilitates communication with other devices over one or more external ports  124  and also includes various software components for handling data received by RF circuitry  108  and/or external port  124 . External port  124  (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  130  may detect contact with touch screen  112  (in conjunction with display controller  156 ) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module  130  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  130  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  130  and display controller  156  detect contact on a touchpad. 
     Contact/motion module  130  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  132  includes various known software components for rendering and displaying graphics on touch screen  112  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  132  stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module  132  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  156 . 
     Text input module  134 , which may be a component of graphics module  132 , provides soft keyboards for entering text in various applications (e.g., contacts  137 , e-mail  140 , IM  141 , browser  147 , and any other application that needs text input). 
     GPS module  135  determines the location of the device and provides this information for use in various applications (e.g., to telephone  138  for use in location-based dialing, to camera  143  as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

In an alternative embodiment, device  100  also may accept verbal input for activation or deactivation of some functions through microphone  113 . 
     It should be noted that, although many of the examples herein are given with reference to optical sensors/cameras  164   a - b  (on the front of a device), a rear-facing camera or optical sensor that is pointed opposite from the display may be used instead of or in addition to an optical sensors/cameras  164   a - b  on the front of a device. 
       FIG. 3A  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  3080  includes a first optical sensor/camera unit  3082  with a first focal length  3090  for capturing a first visual field  3086  and a second optical sensor/camera unit  3084  with a first focal length  3092  for capturing a second visual field  3088 . 
     Some embodiments include a first camera unit  3082  (such as one of the cameras described below with respect to  FIG. 3B  and  FIG. 3C ) of a multifunction device capturing a first image of a first visual field  3086 . A second camera unit  3084  (such as one of the cameras described below with respect to  FIG. 3B  and  FIG. 3C ) of the multifunction device  3080  simultaneously captures a second image of a second visual field  3088 . In some embodiments, the first camera unit  3082  includes a first optical package with a first focal length  3090 . In some embodiments, the second camera unit  3084  includes a second optical package (described below with respect to  FIG. 3B , below) with a second focal length  3092 . In some embodiments, the first focal length  3090  is different from the second focal length  3092 , and the first visual field  3086  is a subset of the second visual field  3088 . 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  3080 , includes a first camera unit  3082  of the multifunction device for capturing a first image of a first visual field  3086 . In some embodiments, the first camera unit  3082  includes a first optical image stabilization actuator for moving a first optical package configured for a first focal length  3090 . The camera system further includes second camera  3084  unit of the multifunction device  3080  for simultaneously capturing a 
     second image of a second visual field  3088 . In some embodiments, the second camera unit  3084  includes a second optical image stabilization actuator for moving a second optical package configured for a second focal length  3092 . In some embodiments, the first focal length  3090  is different from the second focal length  3092 . 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  3086  and the second image of the second visual field  3088  a time indexing feature for establishing that the first image of the first visual field  3086  and the second image of the second visual field  3088  correspond as having been simultaneously captured. Some embodiments display the first image of the first visual field  3086  in a screen interface with a control for switching to display of the second image of the second visual field  3088 , and, responsive to an actuation of the control, display the second image of the second visual field  3088  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  3086  and data of the second image of the second visual field  3088 . In some embodiments, the synthetic intermediate image has a third focal length different from each of the first focal length  3090  and the second focal length  3092 , and the synthetic intermediate image has a third visual field different from each of the first visual field  3086  and the second visual field  3088 . Some embodiments preserve storage of the first image of the first visual field  3086  and data of the second image of the second visual field  3088  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  3086  and data of the second image of the second visual field  3088 . In some embodiments, the synthetic intermediate image has is generated by enhancing the first image of the first visual field  3086  using data from the second image of the second visual field  3088 . Some embodiments display the first image of the first visual field  3086  and the second image of the second visual field  3088  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  3082  of a multifunction device  3080  for capturing a first image of a first visual field  3086  and a second camera unit of the multifunction device for simultaneously capturing a second image of a second visual field  3088 . In some embodiments, the first camera unit  3082  includes a first optical package configured for a first focal length  3090 . In some embodiments, the second camera unit  3084  includes a second optical package configured for a second focal length  3092 . In some embodiments, the first focal length  3090  is different from the second focal length  3092 . 
     In some embodiments, the camera system includes a processing unit configured to assign to the first image of a first visual field  3086  and the second image a time indexing feature for establishing that the first image and the second image of a second visual field  3088  were simultaneously captured. In some embodiments, the first camera unit  3082  includes a lens having a folded lens configuration (not shown) with a longer focal length  3090  than a focal length  3092  of a lens of the second camera unit  3084 , and the second visual field  3088  is centered on a second visual axis aligned with a first visual axis on which the first visual field  3086  is centered. In some embodiments, the first camera unit  3082  includes a first moveable lens (shown below with respect to  FIG. 3B ) 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  3084 . 
     In some embodiments, the first camera unit  3082  includes a first moveable lens and a first image sensor attached a chassis of the first  3082  camera unit, and the second camera unit  3084  includes a lens (shown below with respect to  FIG. 3B ) and a second image sensor moveably attached a chassis of the second camera unit. In some embodiments, the first camera unit  3082  and the second camera unit  3084  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  3084  recording 720p (also known as 720 pixels of vertical resolution progressive scan) slow motion video at 240 frames per second while first camera module  3082  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  3080  filming a batter in a baseball game. Recording video of the game with portable multifunction device  3080  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  3084  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  3082  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  3084  as a telephoto camera module in a 240 frames per second slow motion mode while at the same time using first camera module  3082  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  3084  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  3082  can capture a burst of high resolution still images of her smiling face. In some embodiments, first camera module  3082  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. 3B  illustrates a user interface for a multiple camera system for portable zoom, according to at least some embodiments. A portable multifunction device  400  displays a first image of a first visual field  404  captured by a first camera unit and a second image of a second visual field  402  simultaneously captured by a second camera unit of the multifunction device  400 . A zoom control  406  is displayed within first image of a first visual field  404 . In the embodiment shown, zoom control  406  is an area of first image of first visual field  404 , that, in response to control actuation through the touch screen of portable multifunction device  400 , is used as a control for toggling the display mode for displaying first image of a first visual field  404  captured by a first camera unit and second image of a second visual field  402  simultaneously captured by a second camera unit of the multifunction device  400 . 
     Some embodiments assign metadata to the first image  404  and the second image  402  for a time indexing feature for establishing that the first image  404  and the second image  402  correspond as having been simultaneously captured. Some embodiments display the first image  404  in a screen interface with a control (e.g., similar to control  406 ) for switching to display of the second image  402 , and, responsive to an actuation of the control  406 , display the second image  402  in place of the first image  404 . Some embodiments generate a synthetic intermediate image at least in part from data of the first image  404  and data of the second image  402 . 
       FIG. 3C  depicts a side view of an example embodiment of camera module, according to at least some embodiments. Camera module  3000 , which is an embodiment of cameras  164   a - b , discussed below includes camera components such as an optics module (e.g., a lens barrel)  3002  attached to an optics holder  3003  and a magnet holder  3006 . An image sensor  3070 , which may or may not be mounted on a substrate that is not shown separately in  FIG. 3 , is attached to a camera module base  3008 . The camera components may further include, in addition to components such as power and remote control connections not shown, a cover  3012  and suspension wires  3020 . 
     Optics module  3002  may be suspended on the base assembly  3008  by suspension of the upper springs  3030  and the suspension wires  3020 . Camera components may include one or more of, but are not limited to, optics  3002 , optics holder  3003 , magnet holder(s)  3006 , upper spring(s)  3030 , and lower spring(s)  3032 . 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)  3002  may be screwed, mounted or otherwise held in or by an optics holder  3003 . In at least some embodiments, the optics  3002 /optics holder  3003  assembly may be suspended from or attached to the magnet holder  3006  by upper spring(s)  3030 , and lower spring(s)  3032 . Note that upper spring(s)  3030  and lower spring(s)  3032  are flexible to allow the optics assembly  3000  a range of motion along the Z (optical) axis for optical focusing, wires  3020  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)  3006 , but may include a yoke or other structure  3006  that may be used to help support the optics assembly on suspension wires  3020  via upper springs  3030 . In general, other embodiments of an optics assembly  3000  may include fewer or more components than the example optics assembly  3000  shown in  FIG. 3 . Also note that, while embodiments show the optics assembly  3000  suspended on wires  3020 , other mechanisms may be used to suspend an optics assembly  3000  in other embodiments. 
     The autofocus yoke (e.g., magnet holder(s)  3006 ) acts as the support chassis structure for the autofocus mechanism of actuator  3000 . The lens carrier (optics holder  3003 ) is suspended on the autofocus yoke by an upper autofocus (AF) spring  3030  and a lower optics spring  3032 . 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  3030  and lower spring  3032  also resist the Lorentz forces, and hence convert the forces to a displacement of the lens. This basic architecture shown in  FIG. 3  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  3000  support structure may be achieved by the use of four corner wires  3020 , for example wires with a circular cross-section. Each wire  3020  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  3020  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  3020  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. 4A-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. 4A-4C  includes a different view of a camera unit  400   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. Each of camera units  400   a - c  includes one of optics packages  402   a - c  and one of optical image stabilization actuators  404   a - c  for moving the optical package  402   a - c  configured for focal length or an adjustable range of focal lengths.  FIG. 4D  is a legend indicating the motion capability of various components illustrated in each of  FIGS. 4A-C . 
     Optical stabilization actuators  404   a - c  include magnet arrays  406   a - c  and  418   a - c , which include central magnet arrays  406   a - c  and distal magnet arrays  418   a - c . In some embodiments, central magnet arrays  406   a - c  and distal magnet arrays  418   a - c  are arranged in opposing and mutually-cancelling pairs of magnets. Additionally, in some embodiments, lower magnet arrays  420   b - c  and upper magnet array  422   b  are arranged in analogous opposing and mutually-cancelling pairs. In some embodiments, the designation of central magnet arrays  406   a - c  and distal magnet arrays  418   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 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.
