This disclosure relates generally to a camera actuator and/or suspension system and more specifically to an actuator/suspension system for an image sensor in a camera with a moving image sensor arrangement.
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 for integration into the small, mobile multipurpose devices. Some small form factor cameras may incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens. Some small form factor cameras may incorporate an autofocus (AF) mechanism whereby an object focal distance can be adjusted to focus an object plane in front of the camera at an image plane to be captured by an image sensor of the camera. In some such autofocus mechanisms, the optical lens is moved as a single rigid body along the optical axis (referred to as the Z axis) of the camera to refocus the camera.
In addition, high image quality is easier to achieve in small form factor cameras if lens motion along the optical axis is accompanied by minimal parasitic motion in the other degrees of freedom, for example on the X and Y axes orthogonal to the optical (Z) axis of the camera. Thus, some small form factor cameras that include autofocus mechanisms may also incorporate optical image stabilization (OIS) mechanisms that may sense and react to external excitation/disturbance by adjusting location of the optical lens on the X and/or Y axis in an attempt to compensate for unwanted motion of the lens.
In some embodiments, a camera includes a lens holder, an image sensor, and a flexure assembly that supports the image sensor relative to the lens holder. The lens holder includes one or more lens elements coupled to the lens holder, wherein the lens elements define an optical axis for the camera. The image sensor is configured to capture light passing through the one or more lens elements and is configured to convert the captured light into image signals. The flexure assembly supports the image sensor above or below the lens holder and includes a first frame coupled to the image sensor, a second frame coupled to a stationary component of the camera, a first layer of flexure arms, and a second layer of flexure arms. The first frame coupled to the image sensor is configured to move with the image sensor and receive image signals generated by the image sensor. The first and second layers of flexure arms are each configured to mechanically connect the first frame to the second frame and are configured to provide respective paths for electrical traces that route the image signals from the first frame to the second frame. The second frame may include one or more connectors that connect the second frame to circuits of the camera that further process the image signals or cause the image signals to be displayed. The second layer of flexure arms is mounted above or below the first layer of flexure arms, wherein the first layer of flexure arms and the second layer of flexure arms are separated, at least in part, by an open space between the layers of flexure arms.
The arrangement of multiple layers of flexure arms of a flexure, one above the other, in a camera or voice coil motor actuator may provide greater stiffness in a Z-direction along an optical axis of the camera than in an X or Y direction orthogonal to the optical axis. This arrangement may also cause an image sensor coupled to a dynamic platform of the flexure assembly to maintain a constant or near constant Z-position, while allowing the image sensor to move in the X and Y directions, for example in response to optical image stabilization (OIS) actuation. Additionally, the use of multiple layers of flexure arms in a flexure assembly may provide more paths for electrical traces than if a single layer of flexure arms were used in the flexure assembly. This in turn may allow a flexure assembly, comprising multiple layers of flexure arms, to be more compact as compared to a single layer flexure assembly while still being able to transmit a similar or greater volume of image signals.
In some embodiments, a voice coil motor actuator includes one or more actuator magnets, one or more actuator coils, a dynamic platform configured to be coupled to an image sensor and a static platform, wherein the dynamic platform is configured to move relative to the static platform (though the static platform may also move relative to other components of the camera). The voice coil motor actuator also includes a first layer of flexure arms configured to mechanically connect the dynamic platform to the static platform. Additionally, the voice coil motor actuator includes a second layer of flexure arms, mounted above or below the first layer of flexure arms, and configured to mechanically connect the dynamic platform to the static platform. The first layer of flexure arms and the second layer of flexure arms are separated at least in part by an open space between the respective flexure arms of the first layer and the second layer. The one or more actuator magnets and the one or more actuator coils are configured to magnetically interact to move the dynamic platform relative to the static platform in a plurality of directions parallel to a plane running through the first layer and the second layer of flexure arms.
In some embodiments, a mobile multifunction device includes a camera module comprising one or more lens elements that define an optical axis and an image sensor configured to capture light passing through the one or more lens elements and convert the captured light into image signals. The mobile multifunction device also includes a dynamic frame coupled with the image sensor, a static frame, a first layer of flexure arms that mechanically connect the dynamic frame to the static frame, and a second layer of flexure arms, mounted above or below the first layer of flexure arms, that mechanically connect the dynamic frame to the static frame. The dynamic frame and flexure arms are configured to allow the dynamic frame to move relative to the static frame. The first layer of flexure arms and the second layer of flexure arms are separated at least in part by an open space between the flexure arms of the first layer and the second layer. The mobile multifunction device also includes electrical traces configured to convey the image signals from the dynamic frame to the static frame. Additionally, the mobile multifunction device includes a display and one or more processors configured to cause the display to present an image based at least in part on one or more of the image signals that have been conveyed from the dynamic frame to the static frame via the electrical traces.
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.
In some embodiments, a multi-layered flexure assembly comprises a dynamic platform, a static platform, and multiple layers of flexure arms connecting the static and dynamic platforms. The dynamic platform may comprise a first frame that couples with an image sensor. The static platform may comprise a second frame that couples with a static portion of a camera, such as a circuit board that receives image signals from the image sensor via electrical traces routed over flexure arms mechanically connecting the dynamic and static platforms. The multi-layered flexure may further comprise spacer elements that mechanically connect flexure arms of an upper layer of flexure arms to flexure arms of a lower layer of flexure arms at respective points along respective spans of the flexure arms of the upper and lower layers. For example, spacer elements that mechanically connect flexure arms at different levels of a multi-layered flexure may effectively reduce the beam length of the flexure arms by restricting motion of the flexure arms relative to one another in the Z-direction where the flexure arms of different layers are mechanically connected to each other. This may cause the multi-layered flexure to have a greater stiffness in the Z-direction than in the X or Y directions. For example, a dynamic platform that supports an image sensor of a multi-layered flexure may have a stiffness that restricts motion of the image sensor in the Z-direction (e.g. along the optical axis) that is as much as three times the stiffness of a single layer flexure in the Z-direction. Also, the multi-layer flexure may have a stiffness in the X-direction and/or the Y-direction that is similar to the stiffness in the X-direction and/or the Y-direction of a single layer flexure. Thus, a multi-layer flexure may provide greater Z-stiffness (and therefore greater image sensor stability along the optical axis) than a single-layer flexure while still being flexible in the X and Y directions such that magnets and coils of a voice coil motor may cause the image sensor to move in the X and Y directions.
Also, in some embodiments, a multi-layered flexure may have a smaller footprint than a single layered flexure. For example, in some embodiments, electrical traces may be routed via flexure arms of a multi-layered flexure using flexure arms of more than one layer. Accordingly, since there are multiple layers of flexure arms, there are more flexure arms in an X-Y footprint of a multi-layer flexure to route electrical traces than would be the case in a single layer flexure. For example, electrical traces may be routed on flexure arms of different layers of the multi-layer flexure, thus reducing a number of flexure arms necessary to be included in each layer of the multi-layer flexure to route a given number of electrical traces.
Also, in some embodiments, a multi-layer flexure may use a thinner metal material for each layer of the multiple layers than is used for a flexure comprising only a single layer. This is because the Z-stiffness of the multi-layer flexure results from the combined stiffness of the multiple layers and is further affected by mechanical connections between layers via spacer elements. The combination of layers may form a structure that is stiffer in the Z-direction than the stiffness of any individual layer, and therefore may permit the separate layers to be constructed of a thinner material than would be required to achieve a similar Z-stiffness using a single layer flexure. The use of a thinner metal material for each of the layers of a multi-layer flexure may improve manufacturability of the multi-layer flexure as compared to a flexure comprising only a single layer by reducing issues in regard to etching that make fabrication of a single layer flexure with a thicker metal layer more difficult.
In some embodiments, a multi-layer flexure may further include one or more flexure stabilizers that restrict motion of flexure arms relative to one another within a layer of a multi-layer flexure. For example, a flexure stabilizer may connect flexures, in a same layer, in a plane orthogonal to the optical axis, whereas a spacer element may connect flexures in different layers in a plane parallel to the optical axis.
In some embodiments, a Z-stiffness, an X-stiffness, and/or a Y-stiffness of a multi-layer flexure may be tuned by adjusting a number of flexure arms included in the multi-layer flexure, by adjusting a thickness of the flexure arms included in the multi-layer flexure, by including more or fewer spacer elements in the multi-layer flexure, by adjusting relative positions of spacer elements included in the multi-layer flexure and/or by adjusting a number or position of flexure stabilizers included in the multi-layer flexure. In some embodiments, other variables may be adjusted to adjust a Z-stiffness, an X-stiffness, and/or a Y-stiffness of a multi-layer flexure.
Multi-layer flexure 102 includes static platform/static frame 104, dynamic platform/dynamic frame 106, and flexure arms 108. Multi-layer flexure 102 also includes spacer elements 110 that mechanically connect flexure arms 108 of different layers to one another at respective points along the respective spans of the flexure arms 108. Additionally, multi-layer flexure 102 includes flexure stabilizers 120 that maintain separation between flexure arms 108 in a given layer of the multiple layers of the multi-layer flexure 102.
In some embodiments, a static platform, such as static platform 104, may include a second frame that surrounds the flexure arms 108 and the dynamic platform 106. In some embodiments, a second frame and a static platform may be the same component or a second frame may be coupled to a static platform as two components coupled together. In some embodiments, a dynamic platform, such as dynamic platform 106, may be located within a circumference at least partially formed by flexure arms, such as flexure arms 108, and may include a first frame. In some embodiments, the dynamic platform and a first frame may be the same component, or a first frame may be coupled to a dynamic platform as two components coupled together. In some embodiments, a dynamic platform, such as dynamic platform 106, may be formed by an image sensor coupled to a first frame that is located within a second frame and that is mechanically connected to the second frame via flexure arms at multiple layers of the multi-layer flexure.
In some embodiments, the flexure arms 108 may enable the dynamic platform 106 and/or first frame to move relative to the static platform 104 and/or second frame. Note that in some embodiments, the static platform 104 and/or second frame may be coupled to a fixed structure of a camera or mobile device or may be coupled to another component of a camera or mobile device that is able to move relative to other components of the camera or mobile device. It worth pointing out that when a multi-layer flexure is included in a voice coil motor (VCM), a first frame may include a dynamic platform that couples with another component of the camera such as an image sensor. Also, a second frame may include a static platform that couples with another component of the camera such as a printed circuit board or structural element of the camera. In some embodiments, the first frame may include multiple dynamic platform layers of the multi-layer flexure that are coupled together via a spacer material and the second frame may include multiple stat platform layers that are coupled together via a spacer material. Furthermore, the first frame may also include electrical traces carried on or more of the dynamic platform layers. Also, the second frame may include electrical traces carried on one or more of the static platform layers, wherein the flexure arms also carry electrical traces connecting the electrical traces of the dynamic platform layers to the electrical traces of the static platform layers.
In some embodiments, spacer elements, such as spacer elements 110, may be located along a span of a flexure arm at a location that is roughly midway between a connection of the flexure arm to a static or dynamic platform and a flexure stabilizer, such as one of flexure stabilizers 120. In some embodiments, wherein connections between the flexure arms and the static or dynamic platforms are staggered within a layer of the multi-layer flexure, the spacer elements, such as spacer elements 110, may be staggered in a similar pattern such that the spacer elements are at the mid-points of the respective spans of the respective flexure arms, such as flexure arms 108. In some embodiments, a portion of the flexure arms corresponding to the spacer elements, such as spacer elements 110, may be slightly larger than other portions of the flexure arms as shown in
As discussed in more detail below in regard to
In some embodiments, a multi-layer flexure such as multi-layer flexure 102, may include four or fewer flexure arms per layer in a given quadrant of the multi-layer flexure. For example, multi-layer flexure 102 illustrated in
As shown in
In some embodiments, flexure stabilizer members, such as flexure stabilizers 120, may be configured to mechanically connect flexure arms 108 of upper layer 114 with other flexure arms 108 of upper layer 114 to prevent interference between the flexure arms of the same layer. For example, when the flexure arms of a given layer are deformed due to the dynamic platform shifting in the X-direction or Y-direction, the flexure stabilizers 114 may maintain spacing between the flexure arms at a location of the flexure stabilizer, such as a corner of the multi-layer flexure 102. In a similar manner, flexure stabilizers of lower layer 112 may prevent interference between the flexure arms 108 of the lower layer 112. For example, the flexure stabilizers 120 may constrain movement of the flexure arms of the upper layer 114 or the lower layer 112 relative to other ones of the flexure arms of the respective upper or lower layer in a plane running through the upper or the lower layer.
In some embodiments, the spacer elements 110 may be placed at a mid-point along a span of the respective flexure arms between a connection to the static platform or a connection to the dynamic platform and a respective flexure stabilizer at a corner of the flexure arms between the static platform and the dynamic platform.
In some embodiments, electrical traces may be routed from a dynamic platform, such as dynamic platform 106, to a static platform, such as static platform 104, via flexure arms, such as flexure arms 108. In some embodiments, the electrical traces may be electrically isolated from the metal flexure arms by polymide insulator layers. In some embodiments, the flexure arms may carry multiple layers of electrical signal traces electrically isolated from the metal flexure bodies of the flexure arms and from one another by polymide insulator layers. In some embodiments, other types of insulators and trace elements may be used.
For example,

In some embodiments, an image sensor mounted to a dynamic platform, such as image sensor 308 mounted on dynamic platform 322 (shown in
In some embodiments, a multi-layer flexure, such as multi-layer flexure 102, may include electrical traces on both upper and lower flexure layers. For example, in some embodiments, upper flexure layer 114 and spacer material 116 may include openings (not shown) adjacent to or similar to connectors 126 that allow some elements of a connector to pass through the upper layer 114 and the spacer material 116 to engage with connectors (not shown) on an upper surface of lower layer 112. Also, in some embodiments connectors may be located on opposite sides of a multi-layer flexure assembly, such as multi-layer flexure 102. For example, a first set of connectors may be located on an outward facing surface of an upper flexure layer 114 and another set of connectors may be located on an outward facing surface of a lower flexure layer 112. In such embodiments, one or more vias may pass between the layers to transmit signals/power between electrical traces on the upper flexure layer 114 and electrical traces on the lower flexure layer 112. Also, in some embodiments, a spacer element 110 may include a spacer material 116 and a via (not shown) that passes through the spacer material to connect electrical traces located on the respective upper flexure layer 114 and lower flexure layer 112. Additionally, though not shown in each figure, other multi-layer flexures as described herein, such as in in
In some embodiments, a compact camera module that includes a multi-layer flexure may also include actuators to deliver functions such as autofocus (AF) and optical image stabilization (OIS). One approach to delivering a very compact actuator for OIS is to use a Voice Coil Motor (VCM) arrangement.
In some embodiments, an optical image stabilization voice coil motor (OIS VCM) actuator is designed such that the image sensor is mounted on a dynamic frame which translates in X and Y. An image sensor (wirebonding, flip/chip, BGA) may be mounted on the dynamic platform with run out electrical signal traces using an additive copper deposition process to connect the image sensor from the dynamic platform to the static platform. Flexure arms connect the dynamic platform to the static platform and support electrical signal traces formed via the additive copper deposition process. Optical image stabilization (OIS) coils are mounted on the dynamic platform. In some embodiments, the OIS coils interact with shared permanent magnets that are also used as part of an autofocus (AF) voice coil motor. In some embodiments, OIS permanent magnets are mounted on a static portion of the optical image stabilization actuator to provide additional Lorentz force (e.g. in case of high in-plane flexure stiffness).
Some embodiments include a camera. The camera may include a lens, an image sensor, and an autofocus voice coil motor (AF VCM) actuator. The lens may include one or more lens elements mounted in a lens holder that define an optical axis for the camera (e.g. Z-axis). The image sensor may be configured to capture light passing through the lens elements. Furthermore, the image sensor may be configured to convert the captured light into image signals that are routed over electrical traces mounted on the flexure arms to other components of the camera, such as other circuits that further process the image signals or cause the captured image to be stored or displayed.
In some embodiments, a camera actuator includes an actuator base, an autofocus voice coil motor, and an optical image stabilization voice coil motor. In some embodiments, the autofocus voice coil motor includes a lens holder mounting attachment moveably mounted to the actuator base, a plurality of shared magnets mounted to the actuator base, and an autofocus coil fixedly mounted to the lens holder mounting attachment for producing forces for moving the lens holder in a direction of an optical axis of one or more lenses of the lens holder. In some embodiments, the optical image stabilization voice coil motor includes an image sensor carrier (e.g. dynamic platform) moveably mounted to the actuator base, and a plurality of optical image stabilization coils moveably mounted to the dynamic platform within the magnetic fields of the shared magnets, for producing forces for moving the dynamic platform in a plurality of directions orthogonal to the optical axis.
In some embodiments, shifting the image sensor allows reduction of the moving mass, and therefore there is a clear benefit in power consumption in comparison to OIS “optics shift” designs. In some embodiments, manufacturing is accomplished with the electrical traces being directly deposited on the multi-layer flexure, using an additive copper deposition process, which enables smaller size package while satisfying the I/O requirements.
In some embodiments, the optical image stabilization coils are mounted on a flexible printed circuit carrying power to the coils for operation of the optical image stabilization voice coil motor.
In some embodiments, the optical image stabilization coils are corner-mounted on a flexible printed circuit mechanically connected to the actuator base and mechanically isolated from the autofocus voice coil motor.

In some embodiments, a camera actuator 400 includes an actuator base 414, an autofocus voice coil motor 410 and an optical image stabilization voice coil motor 420. The autofocus voice coil motor 410 includes a lens carrier 406 moveably mounted to the actuator base 414 via an autofocus VCM suspension system 412, a plurality of shared magnets 416 mounted to the base 414 via the suspension system 412, and an autofocus coil 418 fixedly mounted to the lens carrier 406 for producing forces in a direction of an optical axis of one or more lens elements of the lens carrier 406.
In some embodiments, the optical image stabilization voice coil motor 420 includes an image sensor carrier 422 (e.g. a dynamic platform) moveably mounted to the actuator base 414 and a plurality of optical image stabilization coils 430 mounted to the image sensor carrier 422 within the magnetic fields 402 of the shared magnets 416, for producing forces 404 for moving the image sensor carrier 422 in a plurality of directions orthogonal to the optical axis.
In some embodiments, the image sensor carrier 422 further includes one or more flexible members 428 (e.g. flexure arms at multiple layers of a multi-layered flexure) for mechanically connecting an image sensor 424 resting on the image sensor carrier 422 to a frame or static platform 408 of the optical image stabilization voice coil motor 420.
In some embodiments, the flexible members (e.g. flexure arms) 428 mechanically and electrically connect an image sensor 424 resting in the image sensor carrier 422 (e.g. dynamic platform) to a frame 408 (e.g. static platform) of the optical image stabilization voice coil motor 420, and the flexible members (e.g. flexure arms) 428 include electrical signal traces. In some embodiments, the flexures arms or flexible members 428 include metal flexure bodies carrying electrical signal traces electrically isolated from the metal flexure bodies by polymide insulator layers. In some embodiments, the optical image stabilization coils 430 are mounted on a flexible printed circuit 426 carrying power to the coils 430 for operation of the optical image stabilization voice coil motor. In some embodiments, the optical image stabilization coils 430 are corner-mounted on a flexible printed circuit 426 mechanically connected to the actuator base 414 and mechanically isolated from the autofocus voice coil motor 410.

In some embodiments, flexure stabilizers, such as flexure stabilizers 610, constrain movement of flexure arms 606 relative to one another at a corner of a flexure arm arrangement (or at another location) in a plane running through a layer of the multi-layer flexure, such as a plane parallel to upper layer 612 and/or lower layer 614. Also, the spacer elements may constrain movement of flexure arms 606 relative to flexure arms of an upper or lower layer in a plane orthogonal to a plane running through upper layer 612 and/or lower layer 614.

In some embodiments, a multi-layer flexure, such as multi-layer flexure 102, or any of the multi-layer flexures described herein, may include two or more flexure layers. For example, a multi-layer flexure may include “N” flexure layers in some embodiments, wherein “N” is a number greater than one. For example, in some embodiments, a multi-layer flexure may include 2, 3, 4, or . . . up to “N” flexure layers. For example, the ellipses in

In some embodiments, some layers may include electrical traces, while other layers do not include electrical traces. For example, some layers may be added to increase a Z-stiffness of a multi-layer flexure, but may not be used to route electrical traces. Conversely, in some embodiments, multiple layers, or all layers, may include flexure arms with electrical traces routed via the flexure arms.
In some embodiments, more than one spacer material may be used. For example, in some embodiments, an adhesive spacer material may be used to bond static platform layers together or to bond dynamic platform layers together, and a solder spacer material may be used to bond layers together at spacer elements.
In some embodiments, a multi-layer flexure with two or more layers may include an additional spacer material similar to spacer material 806 that includes flexure stabilizers 808 and spacer elements 810. The additional spacer material may be located beneath flexure layer 804 and an additional flexure layer similar to flexure layer 804 may be located beneath the additional spacer material. In some embodiments, this pattern may be repeated to add any number of layers to a multi-layer flexure. In some embodiments, multiple ones or all of the layers of a multi-layer flexure may include electrical traces. Also, in some embodiments, some layers of a multi-layer flexure may carry electrical traces while others do not. For example, for a multi-layer flexure with three layers, an upper outer layer and a lower outer layer may include electrical traces, while a middle layer does not (or only includes vias that connect the upper and lower layers). In other embodiments, electrical traces may be carried bay all three layers or other combinations of layers of the three layered flexure.
In various embodiments, one or more of the flexure stabilizer members described herein may have cross-sections that are similar to, or identical to, one or more of the flexure arms described herein (e.g., with reference to
In some examples, the dynamic platform and/or the static platform of a multi-layer flexure may include one or more offsets (e.g., a recessed portion, an extruded portion, etc.). In some cases, one or more flexure arms may connect to the dynamic platform and/or the static platform at an offset. For instance, the dynamic platform may include two recessed portion offsets at opposing sides of the dynamic platform.

In some alternate embodiments, input controller(s) 1160 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., 1208,
Touch-sensitive display 1112 provides an input interface and an output interface between the device and a user. Display controller 1156 receives and/or sends electrical signals from/to touch screen 1112. Touch screen 1112 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 1112 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 1112 and display controller 1156 (along with any associated modules and/or sets of instructions in memory 1102) detect contact (and any movement or breaking of the contact) on touch screen 1112 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 1112. In an example embodiment, a point of contact between touch screen 1112 and the user corresponds to a finger of the user.
Touch screen 1112 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 1112 and display controller 1156 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 1112. 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 1112 may have a video resolution in excess of 800 dpi. In some embodiments, the touch screen has a video resolution of approximately 860 dpi. The user may make contact with touch screen 1112 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 desired by the user.
In some embodiments, in addition to the touch screen, device 1100 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 1112 or an extension of the touch-sensitive surface formed by the touch screen.
Device 1100 also includes power system 1162 for powering the various components. Power system 1162 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 1100 may also include one or more optical sensors or cameras 1164.
Device 1100 may also include one or more proximity sensors 1166.
Device 1100 includes one or more orientation sensors 1168. In some embodiments, the one or more orientation sensors 1168 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 1168 include one or more gyroscopes. In some embodiments, the one or more orientation sensors 1168 include one or more magnetometers. In some embodiments, the one or more orientation sensors 1168 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 1100. In some embodiments, the one or more orientation sensors 1168 include any combination of orientation/rotation sensors.
In some embodiments, the software components stored in memory 1102 include operating system 1126, communication module (or set of instructions) 1128, contact/motion module (or set of instructions) 1130, graphics module (or set of instructions) 1132, text input module (or set of instructions) 1134, Global Positioning System (GPS) module (or set of instructions) 1135, arbiter module 1158 and applications (or sets of instructions) 1136. Furthermore, in some embodiments memory 1102 stores device/global internal state 1157. Device/global internal state 1157 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 1112; sensor state, including information obtained from the device's various sensors and input control devices 1116; and location information concerning the device's location and/or attitude.

Communication module 1128 facilitates communication with other devices over one or more external ports 1124 and also includes various software components for handling data received by RF circuitry 1108 and/or external port 1124. External port 1124 (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.
Contact/motion module 1130 may detect contact with touch screen 1112 (in conjunction with display controller 1156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 1130 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 1130 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 1130 and display controller 1156 detect contact on a touchpad.
Contact/motion module 1130 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 1132 includes various known software components for rendering and displaying graphics on touch screen 1112 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 1132 stores data representing graphics to be used. Each graphic may be assigned a corresponding code. Graphics module 1132 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 1156.
Text input module 1134, which may be a component of graphics module 1132, provides soft keyboards for entering text in various applications (e.g., contacts 1137, e-mail 1140, IM 1141, browser 1147, and any other application that needs text input).
GPS module 1135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 1138 for use in location-based dialing, to camera 1143 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 various embodiments, system memory 1320 may be implemented using any suitable memory technology, such as static random access memory (SRAM), synchronous dynamic RAM (SDRAM), nonvolatile/Flash-type memory, or any other type of memory. In the illustrated embodiment, program instructions 1322 may be configured to implement a lens control application 1324 incorporating any of the functionality described above. Additionally, existing camera control data 1332 of memory 1320 may include any of the information or data structures described above. In some embodiments, program instructions and/or data may be received, sent or stored upon different types of computer-accessible media or on similar media separate from system memory 1320 or computer system 1300. While computer system 1300 is described as implementing the functionality of functional blocks of previous Figures, any of the functionality described herein may be implemented via such a computer system.
In one embodiment, I/O interface 1330 may be configured to coordinate I/O traffic between processor 1310, system memory 1320, and any peripheral devices in the device, including network interface 1340 or other peripheral interfaces, such as input/output devices 1350. In some embodiments, I/O interface 1330 may perform any necessary protocol, timing or other data transformations to convert data signals from one component (e.g., system memory 1320) into a format suitable for use by another component (e.g., processor 1310). In some embodiments, I/O interface 1330 may include support for devices attached through various types of peripheral buses, such as a variant of the Peripheral Component Interconnect (PCI) bus standard or the Universal Serial Bus (USB) standard, for example. In some embodiments, the function of I/O interface 1330 may be split into two or more separate components, such as a north bridge and a south bridge, for example. Also, in some embodiments some or all of the functionality of I/O interface 1330, such as an interface to system memory 1320, may be incorporated directly into processor 1310.
Network interface 1340 may be configured to allow data to be exchanged between computer system 1300 and other devices attached to a network 1385 (e.g., carrier or agent devices) or between nodes of computer system 1300. Network 1385 may in various embodiments include one or more networks including but not limited to Local Area Networks (LANs) (e.g., an Ethernet or corporate network), Wide Area Networks (WANs) (e.g., the Internet), wireless data networks, some other electronic data network, or some combination thereof. In various embodiments, network interface 1340 may support communication via wired or wireless general data networks, such as any suitable type of Ethernet network, for example; via telecommunications/telephony networks such as analog voice networks or digital fiber communications networks; via storage area networks such as Fibre Channel SANs, or via any other suitable type of network and/or protocol.
Input/output devices 1350 may, in some embodiments, include one or more display terminals, keyboards, keypads, touchpads, scanning devices, voice or optical recognition devices, or any other devices suitable for entering or accessing data by one or more computer systems 1300. Multiple input/output devices 1350 may be present in computer system 1300 or may be distributed on various nodes of computer system 1300. In some embodiments, similar input/output devices may be separate from computer system 1300 and may interact with one or more nodes of computer system 1300 through a wired or wireless connection, such as over network interface 1340.
