Mobile zoom using multiple optical image stabilization cameras

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.

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.

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 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.

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.

FIG. 12A depicts an example embodiment of a camera system 1200a including a first camera unit 1202a and a second camera unit 1202b, according to some embodiments.

The first camera unit 1202a may include a first voice coil motor (VCM) actuator configured to move a first optical package (e.g., the first optical packages 1206b, 1206c 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 1202a 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 first VCM actuator of the first camera unit 1202a 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 1202a. 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 1202a. 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 1202a.

In some examples, the first VCM actuator may include a first magnet 1206a, a second magnet 1208a, a third magnet 1210a, and a fourth magnet 1212a. The magnets 1206a-1212a may form the symmetric magnet arrangement. The first camera unit 1202a may be rectangular in plan, and the magnets 1206a-1212a 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 1202a. For instance, in some embodiments, the magnets 1206a-1212a 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 1202a. As illustrated in FIG. 12A, the magnets 1206a-1212a may be corner magnets. That is, the magnets 1206a-1212a may be individually disposed proximate a respective corner of the first camera unit 1202a.

In some embodiments, the first VCM actuator of the first camera unit 1202a 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 1202a 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 1202a. 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 1202a. 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 1202a.

In some examples, the first VCM actuator may include a first optical image stabilization coil 1214a, a second optical image stabilization coil 1216a, a third optical image stabilization coil 1218a, and a fourth optical image stabilization coil 1220a. The optical image stabilization coils 1214a-1220a may form the symmetric optical image stabilization coil arrangement. The first camera unit 1202a may be rectangular in plan, and the optical image stabilization coils 1214a-1220a 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 1202a. For instance, in some embodiments, the optical image stabilization coils 1214a-1220a 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 1202a. As illustrated in FIG. 12A, the optical image stabilization coils 1214a-1220a may be corner optical image stabilization coils. That is, the optical image stabilization coils 1214a-1220a may be individually disposed proximate a respective corner of the first camera unit 1202a.

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 1202a. 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 1202a.

As a non-limiting example, the first magnet 1206a may be configured to magnetically interact with the first optical image stabilization coil 1214a. The combined arrangement of the first magnet 1206a and the first optical image stabilization coil 1214a 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 1202a. Similarly, the combined arrangement of the second magnet 1208a and a corresponding optical image stabilization coil (e.g., the second optical image stabilization coil 1216a), the combined arrangement of the third magnet 1210a and a corresponding optical image stabilization coil (e.g., the third optical image stabilization coil 1218a), and/or the combined arrangement of the fourth magnet 1212a and a corresponding optical image stabilization coil (e.g., the fourth optical image stabilization coil 1220a) 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 1202a.

In various embodiments, the first VCM actuator of the first camera unit 1202a may include at least one autofocus coil 1222a for actuation along the first optical axis. For instance, the autofocus coil 1222a may be configured to radially surround the first optical package of the first camera unit 1202a. In some embodiments, the autofocus coil 1222a may be octagonal in plan. Some or all of the magnets 1206a-1212a of the first VCM actuator may be individually disposed proximate a respective side of the octagonal autofocus coil 1222a. 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 1204a may include a second VCM actuator configured to move a second optical package (e.g., the second optical packages 1226b, 1224c 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 1204a 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 1204a may include an asymmetric magnet arrangement. For example, the second camera unit 1204a may be rectangular in plan, and the asymmetric magnet arrangement may include a first magnet 1224a (e.g., an actuator lateral magnet) disposed proximate a first side of the second camera unit 1204a, a second magnet 1226a (e.g., an actuator transverse magnet) disposed proximate a second side of the second camera unit 1204a, and a third magnet 1228a (e.g., an actuator transverse magnet) disposed proximate a third side of the second camera unit 1204a. The third side of the second camera unit 1204a may be opposite the second side of the second camera unit 1204a. In some embodiments, no magnets are disposed proximate a fourth side of the second camera unit 1204a. The fourth side of the second camera unit 1204a may be opposite the first side of the second camera unit 1204a.

In some examples, the second VCM actuator of the second camera unit 1204a 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 1230a disposed proximate to the first magnet 1224a of the asymmetric magnet arrangement, a second optical image stabilization coil 1232a disposed proximate to the second magnet 1226a of the asymmetric magnet arrangement, and a third optical image stabilization coil 1234a disposed proximate the third magnet 1228a of the asymmetric magnet arrangement.

In various embodiments, the second VCM actuator of the second camera unit 1202a 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 1236a disposed proximate the second magnet 1226a of the asymmetric magnet arrangement, and a second autofocus coil 1238a disposed proximate the third magnet 1228a of the asymmetric magnet arrangement.

In some embodiments, the first camera unit 1202a may be disposed adjacent to the second camera unit 1204a. For example, the first camera unit 1202a and the second camera unit 1204a may each be rectangular in plan, and the first camera unit 1202a may be disposed adjacent to the second camera unit 1204a 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 1202a and the second optical package of the second camera unit 1204a. The asymmetric magnet arrangement of the second VCM actuator may include a first magnet 1224a disposed proximate a first side of the second camera unit 1204a that is distal to the first axis. Furthermore, the first magnet 1224a 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 1204a that is opposite the first side of the second camera unit 1204a. The second side of the second camera unit 1204a may extend in a direction that is parallel to the first axis. In some examples, a dummy mass (e.g., the dummy mass 1240c illustrated in FIG. 12C) may be disposed proximate the second side of the second camera unit 1204a 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 1224a disposed proximate the first side of the second camera unit 1204a.

In some examples, the first camera unit 1202a may be smaller in one or more dimensions than the second camera unit 1204a. 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 1202a than a corresponding X, Y, and/or Z dimension of the second camera unit 1204a. For instance, the broken line illustrated in FIG. 12A includes a tapered portion 1240a that indicates a difference in size between the first camera unit 1202a and the second camera unit 1204a.

In some embodiments, the first camera unit 1202a may be configured to capture a first image of a first visual field. The second camera unit 1204a may be configured to capture a second image of a second visual field. In some examples, the first camera unit 1202a and the second camera unit 1204a 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 1202a may be configured for a first focal length, and the second optical package of the second camera unit 1204a 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 1202a may be configured with a wide-angle lens and the second optical package of the second camera unit 1204a may be configured with a telephoto lens.

In some embodiments, the first camera unit 1202a and the second camera unit 1204a 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 1202a 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 1204a 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 1202a and/or the second camera unit 1204a 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 1222a of the first VCM actuator may be attached to the first optical package of the first camera unit 1202a. A yoke component (not shown) of the first camera unit 1202a may support and house the four magnets 1206a-1212a of the first VCM actuator. Each of the magnets 1206a-1212a 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 1222a, or away from the autofocus coil 1222a, so that the Lorentz forces from all four magnets act in the same direction along the first optical axis, thereby causing the autofocus coil 1222a 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 1222a, Lorentz forces are developed due to the presence of the four magnets 1206a-1220a, 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 1214a-1220a. In some cases, a first pair of the optical image stabilization coils 1214a-1220a 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 1214a-1220a may be fixed to a base component (e.g., the base 1008 illustrated in FIG. 1C) of the first camera unit 1202a, and when current is appropriately applied, the optical image stabilization coils 1214a-1220a may interact with the magnets 1206a-1212a 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 1202a 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 1236a-1238a of the second VCM actuator may be attached to opposing sides, or opposing portions, of the second optical package of the second camera unit 1204a. A yoke component (not shown) of the first camera unit 1202a may support and house the magnets 1224a-1228a of the second VCM actuator. In some examples, the second magnet 1226a and the third magnet 1228a may each be dual pole magnets that interact with the autofocus coils 1236a-1238a. 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 1226a may be a dual pole magnet that interacts with the first autofocus coil 1236a, and the third magnet 1228a may be a dual pole magnet that interacts with the second autofocus coil 1238a. The interaction between the dual pole magnets 1226a-1228a and the autofocus coils 1236a-1238a 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 1020a 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 1230a-1234a. The optical image stabilization coils 1230a-1234a may be fixed to a base component (e.g., the base 1008 illustrated in FIG. 1C) of the second camera unit 1204a, and when current is appropriately applied, the optical image stabilization coils 1214a-1220a may interact with the magnets 1206a-1212a 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 1232a-1234a may interact with the pair of dual pole magnets 1226a-1228a to deliver controlled motion in a first direction orthogonal to the second optical axis. The first optical image stabilization coil 1230a may interact with the first magnet 1224a, 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 1204a 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.

FIG. 12B depicts an example embodiment of a camera system 1200b including a first camera unit 1202b and a second camera unit 1204b, according to some embodiments. In particular, FIG. 12B illustrates example coil arrangements of the first camera unit 1202b and the second camera unit 1204b. The first camera unit 1202b and the second camera unit 1204b may include magnets (e.g., the example magnet arrangements illustrated in FIG. 12C) configured to magnetically interact with coils of the example coil arrangements.

The first camera unit 1202b may include a first VCM actuator configured to move a first optical package 1206b. For instance, the first VCM actuator may be configured to move the first optical package 1206b along a first optical axis and/or along a first plane that is orthogonal to the first optical axis. The first optical package 1206b may include one or more lenses that define the first optical axis.

In some embodiments, the first VCM actuator of the first camera unit 1202b 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 1202b 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 1202b. 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 1202b. 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 1202b.

In some examples, the first VCM actuator may include a first optical image stabilization coil 1208b, a second optical image stabilization coil 1210b, a third optical image stabilization coil 1212b, and a fourth optical image stabilization coil 1214b. The optical image stabilization coils 1208b-1214b may form the symmetric optical image stabilization coil arrangement. The first camera unit 1202a may be rectangular in plan, and the optical image stabilization coils 1214a-1220a 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 1202b. For instance, in some embodiments, the optical image stabilization coils 1208b-1214b 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 1202b.

As illustrated in FIG. 12B, the optical image stabilization coils 1208b-1214b may be corner optical image stabilization coils. That is, the optical image stabilization coils 1208b-1214b may be individually disposed proximate a respective corner of the first camera unit 1202b. For example, the first optical image stabilization coil 1208b may be disposed proximate a first corner 1216b of the first camera unit 1202b, the second optical image stabilization coil 1210b may be disposed proximate a second corner 1218b of the first camera unit 1202b, the third optical image stabilization coil 1212b may be disposed proximate a third corner 1220b of the first camera unit 1202b, and/or the fourth optical image stabilization coil 1214b may be disposed proximate a fourth corner 1222b of the first camera unit 1202b.

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

The second camera unit 1204b may include a second VCM actuator configured to move a second optical package 1226b. For instance, the second VCM actuator may be configured to move the second optical package 1226b along a second optical axis and/or along a second plane that is orthogonal to the second optical axis. The second optical package 1226b may include one or more lenses that define the second optical axis.

In some examples, the second VCM actuator of the second camera unit 1204b 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 second camera unit 1204b may be rectangular in plan, and the asymmetric optical image stabilization coil arrangement may include a first optical image stabilization coil 1228b, a second optical image stabilization coil 1230b, and a third optical image stabilization coil 1232b. The first optical image stabilization coil 1228b may be disposed proximate a first side 1234b of the second camera unit 1204b. In some examples, the first optical image stabilization coil 1228b may be a racetrack coil with a longitudinal axis that is substantially parallel to the first side 1234b of the second camera unit 1204b. The second optical image stabilization coil 1230b may be disposed proximate a second side 1236b of the second camera unit 1204b. In some examples, the second optical image stabilization coil 1230b may be a racetrack coil with a longitudinal axis that is substantially parallel to the second side 1236b of the second camera unit 1204b. The third optical image stabilization coil 1232b may be disposed proximate a third side 1238b of the second camera unit 1204b. The third side 1238b of the second camera unit 1204b may be opposite the second side 1236b of the second camera unit 1204b. In some examples, the third optical image stabilization coil 1232b may be a racetrack coil with a longitudinal axis that is substantially parallel to the third side 1238b of the second camera unit 1204b.

In some embodiments, no coils are disposed proximate a fourth side 1240b of the second camera unit 1204b. The fourth side 1240b of the second camera unit 1204b may be opposite the first side 1234b of the second camera unit 1204b.

In various embodiments, the second VCM actuator of the second camera unit 1204b 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 1242b and a second autofocus coil 1244b. The first autofocus coil 1242b may be disposed proximate the second optical image stabilization coil 1230b. Additionally or alternatively, the first autofocus coil 1242b may be situated to a first side of the second optical package 1226b. In some examples, the first autofocus coil 1242b may be racetrack coil with a longitudinal axis that is substantially parallel to the second side 1236b of the second camera unit 1204b. In some embodiments, the first autofocus coil 1242b may have a lateral axis that is substantially perpendicular to a lateral axis of the second optical image stabilization coil 1230b. Likewise, the second autofocus coil 1244b may have a lateral axis that is substantially perpendicular to a lateral axis of the third optical image stabilization coil 1232b. Furthermore, the first autofocus coil 1242b may have a longitudinal axis that is substantially parallel to a longitudinal axis of the second optical image stabilization coil 1230b. Similarly, the second autofocus coil 1244b may have a longitudinal axis that is substantially parallel to a longitudinal axis of the third optical image stabilization coil 1232b.

FIG. 12C depicts an example embodiment of a camera system 1200c including a first camera unit 1202c and a second camera unit 1204c, according to some embodiments. In particular, FIG. 12C illustrates example magnet arrangements of the first camera unit 1202c and the second camera unit 1204c. The first camera unit 1202c and the second camera unit 1204c 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 1202c may include a first VCM actuator configured to move a first optical package 1206c. For instance, the first VCM actuator may be configured to move the first optical package 1206c along a first optical axis and/or along a first plane that is orthogonal to the first optical axis. The first optical package 1206c may include one or more lenses that define the first optical axis.

In some embodiments, the first VCM actuator of the first camera unit 1202c 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 1202c. 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 1202c. 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 1202c.

In some examples, the first VCM actuator may include a first magnet 1208c, a second magnet 1210c, a third magnet 1212c, and a fourth magnet 1214c. The magnets 1208c-1214c may form the symmetric magnet arrangement. The first camera unit 1202c may be rectangular in plan, and the magnets 1208c-1214c 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 1202c. For instance, in some embodiments, the magnets 1208c-1214c 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 1202c.

As illustrated in FIG. 12C, the magnets 1208c-1214c may be corner magnets. That is, the magnets 1208c-1214c may be individually disposed proximate a respective corner of the first camera unit 1202c. For example, the first magnet 1208c may be disposed proximate a first corner 1216c of the first camera unit 1202c, the second magnet 1210c may be disposed proximate a second corner 1218c of the first camera unit 1202c, the third magnet 1212c may be disposed proximate a third corner 1220c of the first camera unit 1202c, and/or the fourth magnet 1214c may be disposed proximate a fourth corner 1222c of the first camera unit 1202c.

In some embodiments, the first magnet 1208c, the second magnet 1210c, the third magnet 1212c, and/or the fourth magnet 1214c may each be a single pole magnet. In other embodiments, the first magnet 1208c, the second magnet 1210c, the third magnet 1212c, and/or the fourth magnet 1214c may each be a dual pole magnet. The arrows depicted in FIG. 12C indicate example polarity directions of the magnets.

The second camera unit 1204c may include a second VCM actuator configured to move a second optical package 1224c. For instance, the second VCM actuator may be configured to move the second optical package 1224c along a second optical axis and/or along a second plane that is orthogonal to the second optical axis. The second optical package 1224c may include one or more lenses that define the second optical axis.

In some embodiments, the second VCM actuator of the second camera unit 1204c may include an asymmetric magnet arrangement. For example, the second camera unit 1204c may be rectangular in plan, and the asymmetric magnet arrangement may include a first magnet 1226c (e.g., an actuator lateral magnet) disposed proximate a first side 1228c of the second camera unit 1204c, a second magnet 1230c (e.g., an actuator transverse magnet) disposed proximate a second side 1232c of the second camera unit 1204a, and a third magnet 1234c (e.g., an actuator transverse magnet) disposed proximate a third side 1236c of the second camera unit 1204c. The third side 1236c of the second camera unit 1204c may be opposite the second side 1232c of the second camera unit 1204c.

In some embodiments, no magnets are disposed proximate a fourth side 1238c of the second camera unit 1204c. The fourth side 1238c of the second camera unit 1204c may be opposite the first side 1228c of the second camera unit 1204c. In various examples, a dummy mass 1240c may be disposed proximate the fourth side 1238c of the second camera unit 1204c. The dummy mass 1240c may be configured to act as a counterbalance to the first magnet 1226c disposed proximate the first side 1228c of the second camera unit 1204c.

In some embodiments, the first magnet 1226c may be a single pole magnet. Furthermore, the second magnet 1230c and the third magnet 1234c 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 1226c may be a dual pole magnet, the second magnet 1230c may be a single pole magnet, and/or the third magnet 1234c may be a single pole magnet.

In some embodiments, the first camera unit 1202c may be disposed adjacent to the second camera unit 1204c. For example, the first camera unit 1202c and the second camera unit 1204c may each be rectangular in plan, and the first camera unit 1202c may be disposed adjacent to the second camera unit 1204c along a first axis 1242c that intersects a second axis 1244c. For instance, the second axis 1244c may extend through the first optical package 1206c of the first camera unit 1202c and the second optical package 1224c of the second camera unit 1204c. In some instances, the second axis 1244c may be substantially perpendicular to the first axis 1242c. The first side 1228c of the second camera unit 1228c may be distal to the first axis 1242c. Furthermore, the first magnet 1226c may have a longitudinal axis that is substantially parallel to the first axis 1242c. The fourth side 1238c may be proximal to the first axis 1242c. Furthermore, dummy mass 1240c may have a longitudinal axis that is substantially parallel to the first axis 1242c.

In some non-limiting examples, the first camera unit 1202c and the second camera unit 1204c may be configured such that magnetic interaction between the first camera unit 1202c and the second camera unit 1204c is mitigated. The first VCM actuator of the first camera unit 1202c may include one or more magnets that are disposed proximate the second VCM actuator of the second camera unit 1204c. For instance, in some embodiments, the second magnet 1210c and the third magnet 1212c of the second VCM actuator of the first camera unit 1202c may be disposed proximate the second camera unit 1204c, and thus may be considered as a first set of near magnets relative to the second camera unit 1204c. Similarly, the second VCM actuator of the second camera unit 1204c may include one or more magnets that are disposed proximate the first VCM actuator of the first camera unit 1202c. For instance, the second magnet 1230c and the third magnet 1234c of the second VCM actuator of the second camera unit 1204c may be disposed proximate the first camera unit 1202c, and thus may be considered as a second set of near magnets relative to the first camera unit 1202c.

In various embodiments, each magnet of the first set of near magnets of the first camera unit 1202c may be a single pole magnet, and each magnet of the second set of near magnets of the second camera unit 1204c may be a dual pole magnet. In some cases, such a configuration may mitigate magnetic interaction between the first camera unit 1202c and the second camera unit 1204c. That is, by configuring the first camera unit 1202c and the second camera unit 1204c such that single pole magnets of the first camera unit 1202c and dual pole magnets of the second camera unit 1204c are nearest each other, the magnetic interaction between the camera units 1202c and 1204c may be mitigated relative to some other configurations (e.g, the example magnet arrangement 1300a 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 1202c and the second camera unit 1204c described above with reference to FIG. 12C.

As illustrated in FIG. 13A, the example magnet arrangement 1300a includes a first single pole magnet 1302a and a second single pole magnet 1304a. The first single pole magnet 1302a is adjacent to the second single pole magnet 1304a. The first single pole magnet 1302a may have a first magnetic field 1306a. The second single pole magnet 1304a may have a second magnetic field 1308a. The first magnetic field 1306a may extend away from the first single pole magnet 1302a, and the second magnetic field 1308a may extend away from the second single pole magnet 1304a. For example, the first magnetic field 1306a of the first single pole magnet 1306a may extend toward the second single pole magnet 1304a and the second magnetic field 1308a may extend toward the first single pole magnet 1302a such that the first magnetic field 1306a and the second magnetic field 1308a interact, as indicated by the overlapping magnetic field lines within the dashed line rectangle 1310a.

As illustrated in FIG. 13B, the example magnet arrangement 1300b includes a single pole magnet 1302b and a dual pole magnet 1304b. The single pole magnet 1302b is adjacent to the dual pole magnet 1304b. The single pole magnet 1302b may have a first magnetic field 1306b. The dual pole magnet 1304b may have a second magnetic field 1308b. Due to the respective polarity configurations of the single pole magnet 1302b and the dual pole magnet 1304b, the first magnetic field 1306b may extend away from the single pole magnet 1302b to a greater extent than the second magnetic field 1308b extends away from dual pole magnet 1304b. The tightness of the extension of the second magnetic field 1308b with respect to the dual pole magnet 1304b may mitigate interaction between the second magnetic field 1308b of the dual pole magnet 1304b and the first magnetic field 1306b of the single pole magnet 1302b, e.g., as indicated by the magnetic field lines not overlapping within the dashed line rectangle 1310b. In some examples, the single pole-dual pole magnet arrangement of FIG. 13B is illustrative of mitigated magnetic interaction between the first camera unit 1202c and the second camera unit 1204c described above with reference to FIG. 12C.

FIG. 14A is a flow chart of an example method usable in a multiple camera system for portable zoom, according to at least some embodiments. For instance, the example method may be used in connection with one or more of the embodiments described herein with reference to FIGS. 1A-13B and 15-17. In some embodiments, a first camera unit of a multifunction device, having a first optical package with a first focal length, captures a first image of a first visual field (block 1400). A second camera unit of the multifunction device, having a second optical package with a second focal length different from the first focal length simultaneously captures a second image of a second visual field that is a subset of the first visual field (block 1402). The first image and the second image are preserved to a storage medium as separate data structures (block 1404).

In some embodiments, a first camera unit of a multifunction device, having a first optical package with a first focal length, captures a first image of a first visual field (block 1410). A second camera unit of the multifunction device, having a second optical package with a second focal length different from the first focal length simultaneously captures a second image of a second visual field that is a subset of the first visual field (block 1412). Optical image stabilization is provided to the first camera unit (block 1414). Optical image stabilization is provided to the second camera unit (block 1416).

It should be appreciated that device 1500 is only one example of a portable multifunction device, and that device 1500 may have more or fewer components than shown, may combine two or more components, or may have a different configuration or arrangement of the components. The various components shown in various of the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 1502 may include high-speed random access memory and may also include non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 1502 by other components of device 1500, such as CPU 1520 and the peripherals interface 1518, may be controlled by memory controller 1522.

Peripherals interface 1518 can be used to couple input and output peripherals of the device to CPU 1520 and memory 1502. The one or more processors 1520 run or execute various software programs and/or sets of instructions stored in memory 1502 to perform various functions for device 1500 and to process data.

In some embodiments, peripherals interface 1518, CPU 1520, and memory controller 1522 may be implemented on a single chip, such as chip 1504. In some other embodiments, they may be implemented on separate chips.

RF (radio frequency) circuitry 1508 receives and sends RF signals, also called electromagnetic signals. RF circuitry 1508 converts electrical signals to/from electromagnetic signals and communicates with communications networks and other communications devices via the electromagnetic signals.

The wireless communication may use any of a variety of communications standards, protocols and technologies, including but not limited to Global System for Mobile Communications (GSM), Enhanced Data GSM Environment (EDGE), high-speed downlink packet access (HSDPA), high-speed uplink packet access (HSUPA), wideband code division multiple access (W-CDMA), code division multiple access (CDMA), time division multiple access (TDMA), Bluetooth, Wireless Fidelity (Wi-Fi) (e.g., IEEE 802.11a, IEEE 802.11b, IEEE 802.11g and/or IEEE 802.11n), voice over Internet Protocol (VoIP), Wi-MAX, a protocol for e-mail (e.g., Internet message access protocol (IMAP) and/or post office protocol (POP)), instant messaging (e.g., extensible messaging and presence protocol (XMPP), Session Initiation Protocol for Instant Messaging and Presence Leveraging Extensions (SIMPLE), Instant Messaging and Presence Service (IMPS)), and/or Short Message Service (SMS), or any other suitable communication protocol, including communication protocols not yet developed as of the filing date of this document.

Audio circuitry 1510, speaker 1511, and microphone 1513 provide an audio interface between a user and device 1500. Audio circuitry 1510 receives audio data from peripherals interface 1518, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 1511. Speaker 1511 converts the electrical signal to human-audible sound waves. Audio circuitry 1510 also receives electrical signals converted by microphone 1513 from sound waves. 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 (e.g., 1608, FIG. 16) may include an up/down button for volume control of speaker 1511 and/or microphone 1513. 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 1564a-b. Optical sensors 1564a-b may include charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensors 1564a-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 1564a-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'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 1564a-b are supported, each of the multiple cameras or optical sensors 1564a-b may include its own photo sensor(s), or the multiple cameras or optical sensors 1564a-b may be supported by a shared photo sensor. Likewise, in embodiments in which multiple cameras or optical sensors 1564a-b are supported, each of the multiple cameras or optical sensors 1564a-b may include its own image processing pipeline of processors and storage units, or the multiple cameras or optical sensors 1564a-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'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 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.
