Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit under 35 USC § 119(a) of Korean Patent Application No. 10-2021-0156825, filed on Nov. 15, 2021, in the Korean Intellectual Property Office, the entire disclosure of which is incorporated herein by reference for all purposes. 
     BACKGROUND 
     1. Field 
     The following description relates to a sensor shifting module and camera module having the sensor shifting module. 
     2. Description of Related Art 
     With the development of communications technology, mobile devices such as, but not limited to, smartphones, are widely distributed, and accordingly, the demand for increased functions of the cameras in such mobile devices are gradually increasing. For example, a camera included in a mobile device may be manufactured to provide advanced image capturing functions (e.g., an autofocusing function, an anti-shake function, and the like) implemented in a typical digital single-lens reflex (DSLR) camera despite the small size thereof. 
     The optical image stabilization (OIS) function, for example, the hand shake correction function, is a function that prevents image blurring from occurring when the camera is shaken during the exposure time, and is necessary when images are captured in low-light environments in which there is a lot of shaking and the exposure time is long. Image stabilization is largely divided into Digital image stabilization (DIS), Electronic IS (EIS), and Optical IS (OIS). There-among, OIS (Optical IS) fundamentally blocks image deterioration caused by shaking by moving the lens or image sensor in a direction perpendicular to the optical axis to correct the optical path. Since a mechanical actuator is necessary, the implementation of the device is complicated and provides a best compensation performance at the cost of high price. 
     Since the lens barrel contains an internal optical system, a relatively large amount of force may be necessary to drive the lens barrel. Since the image sensor is relatively light, it is advantageous to implement an excellent image stabilization function even with a small force. However, when the actuator that drives the image sensor includes a permanent magnet, the magnetic field caused by the permanent magnet affects the surrounding electronic components. Specifically, when the mobile device includes multiple cameras disposed adjacently to each other, a permanent magnet inside one camera may negatively affect the operation of a neighboring camera. Therefore, cameras may not be located close to each other, or it may be difficult to dispose electronic components inside the camera.

The drawings may not be to scale, and the relative size, proportions, and depiction of elements in the drawings may be exaggerated for clarity, illustration, and convenience. 
     DETAILED DESCRIPTION 
     The following detailed description is provided to assist the reader in gaining a comprehensive understanding of the methods, apparatuses, and/or systems described herein. However, various changes, modifications, and equivalents of the methods, apparatuses, and/or systems described herein will be apparent after an understanding of the disclosure of this application. For example, the sequences of operations described herein are merely examples, and are not limited to those set forth herein, but may be changed as will be apparent after an understanding of the disclosure of this application, with the exception of operations necessarily occurring in a certain order. Also, descriptions of features that are known, after an understanding of the disclosure of this application, may be omitted for increased clarity and conciseness, noting that omissions of features and their descriptions are also not intended to be admissions of their general knowledge. 
     The features described herein may be embodied in different forms, and are not to be construed as being limited to the examples described herein. Rather, the examples described herein have been provided merely to illustrate some of the many possible ways of implementing the methods, apparatuses, and/or systems described herein that will be apparent after an understanding of the disclosure of this application. 
     Herein, it is noted that use of the term “may” with respect to an example or embodiment, e.g., as to what an example or an example may include or implement, means that at least one example or embodiment exists in which such a feature is included or implemented while all examples and examples are not limited thereto. 
     Throughout the specification, when an element, such as a layer, region, or substrate, is described as being “on,” “connected to,” or “coupled to” another element, it may be directly “on,” “connected to,” or “coupled to” the other element, or there may be one or more other elements intervening therebetween. In contrast, when an element is described as being “directly on,” “directly connected to,” or “directly coupled to” another element, there may be no other elements intervening therebetween. Likewise, expressions, for example, “between” and “immediately between” and “adjacent to” and “immediately adjacent to” may also be construed as described in the foregoing. 
     As used herein, the term “and/or” includes any one and any combination of any two or more of the associated listed items. 
     Although terms such as “first,” “second,” and “third” may be used herein to describe various members, components, regions, layers, or sections, these members, components, regions, layers, or sections are not to be limited by these terms. Rather, these terms are only used to distinguish one member, component, region, layer, or section from another member, component, region, layer, or section. Thus, a first member, component, region, layer, or section referred to in examples described herein may also be referred to as a second member, component, region, layer, or section without departing from the teachings of the examples. 
     Spatially relative terms such as “above,” “upper,” “below,” and “lower” may be used herein for ease of description to describe one element&#39;s relationship to another element as illustrated in the figures. Such spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as being “above” or “upper” relative to another element will then be “below” or “lower” relative to the other element. Thus, the term “above” encompasses both the above and below orientations depending on the spatial orientation of the device. The device may also be oriented in other manners (for example, rotated 90 degrees or at other orientations), and the spatially relative terms used herein are to be interpreted accordingly. 
     The terminology used herein is for the purpose of describing particular examples only, and is not to be used to limit the disclosure. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. As used herein, the term “and/or” includes any one and any combination of any two or more of the associated listed items. As used herein, the terms “include,” “comprise,” and “have” specify the presence of stated features, numbers, operations, elements, components, and/or combinations thereof, but do not preclude the presence or addition of one or more other features, numbers, operations, elements, components, and/or combinations thereof. The use of the term “may” herein with respect to an example or embodiment (for example, as to what an example or embodiment may include or implement) means that at least one example or embodiment exists where such a feature is included or implemented, while all examples are not limited thereto. 
     Unless otherwise defined, all terms, including technical and scientific terms, used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains consistent with and after an understanding of the present disclosure. Terms, such as those defined in commonly used dictionaries, are to be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and are not to be interpreted in an idealized or overly formal sense unless expressly so defined herein. 
     Due to manufacturing techniques and/or tolerances, variations of the shapes illustrated in the drawings may occur. Thus, the examples described herein are not limited to the specific shapes illustrated in the drawings, but include changes in shape occurring during manufacturing. 
     The features of the examples described herein may be combined in various manners as will be apparent after gaining an understanding of the disclosure of this application. Further, although the examples described herein have a variety of configurations, other configurations are possible as will be apparent after gaining an understanding of the disclosure of this application. 
     The drawings may not be to scale, and the relative sizes, proportions, and depiction of elements in the drawings may be exaggerated for clarity, illustration, and convenience. 
     In this document, the X-direction, the Y-direction, and the Z-direction indicate a direction parallel to the X-axis, a direction parallel to the Y-axis, and a direction parallel to the Z-axis illustrated in the drawings, respectively. In addition, unless otherwise stated, the X direction is a concept including both the +X-axis direction and the −X-axis direction, and this is also applied to the Y-direction and the Z-direction. 
     When two directions (or axes) are parallel to or perpendicular to each other in this document, it also includes examples in which the two directions (or axes) are substantially parallel to each other or substantially side by side. For example, the first axis and the second axis being perpendicular to each other indicates that the first axis and the second axis form an angle of 90 degrees or close to 90 degrees. 
     Paragraphs beginning with “in one/an example” in this document do not necessarily refer to the same examples. The specific features, structures, or characteristics may be combined in any suitable manner consistent with the present disclosure. 
     In this document, “configured to” indicates that a component includes a structure necessary to implement a certain function. 
     Hereinafter, an example of the present disclosure will be described in detail with reference to the drawings. However, the spirit of the present disclosure is not limited to the presented example. For example, those skilled in the art who understand the spirit of the present disclosure will be able to propose other examples included within the scope of the spirit of the present disclosure through addition, change or deletion of components, or the like, but this will also be included within the scope of the spirit of the present disclosure. 
     One or more examples relate to a method of implementing optical image stabilization by driving an image sensor. 
     Camera Module 
       FIG.  1    schematically illustrates components constituting an example camera module  1 , in accordance with one or more embodiments. 
     In one example, a camera module  1  includes a lens module  20  including at least one lens  21  and a lens barrel  22  that accommodates the at least one lens  21 , and an image sensor  11 . Light L passes through the lens module  20  and contacts an imaging plane of the image sensor  11 . The camera module  1  may include an AF driving unit  23  that moves the lens module  20  in the optical axis direction to adjust the focal length. The AF driving unit  23  may include, for example, a coil and a magnet facing each other. The coil is fixedly coupled to the lens module  20 , the magnet is coupled to a fixed body such as a housing, and electromagnetic interaction between the coil and the magnet may cause the lens module  20  to move in the optical axis direction. 
     In an example, the camera module  1  may provide an optical image stabilization (hereinafter, ‘OIS’) function. The camera module  1  may provide an OIS function by driving the image sensor  11 . For example, the camera module  1  may include an OIS driver  12  that moves or drives the image sensor  11  in a direction perpendicular to the optical axis, or rotates the image sensor about an axis parallel to the optical axis or about an axis perpendicular to the optical axis. 
     In an example, the camera module  1  may include a sensor shifting module  10 . The sensor shifting module  10  may include components necessary to implement the OIS function by driving the image sensor  11 . For example, the sensor shifting module  10  may include the image sensor  11  and the OIS driver  12  which drives the image sensor  11 . As another example, the sensor shifting module  10  may mean only the OIS driver  12  excluding the image sensor  11 . 
     In one example, the camera module  1  may further include an optical element in addition to the lens module  20  and the image sensor  11 . In one example, the camera module  1  may include two or more lens modules. For example, a first optical element  30  and/or a second optical element  40  may be a lens module distinct from the lens module  20 . 
     In an example, the camera module  1  may include an optical path changing element disposed in front of the lens module  20 . For example, the first optical element  30  may be a prism or a mirror. In another example, the optical path changing element may be disposed between the image sensor  11  and the lens module  20 . For example, the second optical element  40  may be a prism or a mirror. 
     Hereinafter, a sensor shifting module  100  or the OIS driver  120  described with reference to  FIGS.  2  to  9 B  may be applied to the camera module  1  of  FIG.  1   . 
     2. Sensor Shift 
     2.1. Structure 
       FIG.  2    illustrates the sensor shifting module  100  according to an example. The sensor shifting module  100  may include an OIS driver  120  that drives an image sensor  111 . In an example, the OIS driver  120  includes a movable body  110  including the image sensor  111 , and a fixed body  130 . The movable body  110  may be movably disposed inside the fixed body  130 . The movable body  110  is a component that moves together with the image sensor  111 . For example, the movable body  110  may include a sensor substrate  112  on which the image sensor  111  is mounted, and a sensor holder  113  coupled to the sensor substrate  112 . 
     Referring to  FIG.  2   , the sensor holder  113  may include a plate  113   a  connected to the lower portion of the sensor substrate  112 , and an extension portion  113   b  extending upwardly (e.g., in the +Z direction) from the edge of the plate  113   a . The extension portion  113   b  may face a driving coil  122 , and a driving yoke  121  may be seated on the extension portion  113   b . In another example, the driving yoke  121  may be mounted on the fixed body  130 , and the driving coil  122  may be mounted on the sensor holder  113 . In this example, the driving coil  122  and/or the yoke  123  may be seated on the extension portion  113   b.    
     A signal from the image sensor  111  may be transmitted to another electronic component (e.g., an image signal processor (ISP)) through the sensor substrate  112  and a connector  150 . 
     The fixed body  130  may include a base  131  and components fixedly coupled to the base  131 . For example, the fixed body  130  may include the driving coil  122  and a yoke  123  to be described later. 
     Through the OIS driver  120 , the movable body  110  may move in a direction orthogonal to the direction in which the imaging plane  111   a  of the image sensor  111  faces. In an example, the OIS driver  120  may correct the shaking of the camera module  1  or the electronic device in which the image sensor  111  is mounted in a direction perpendicular to an optical axis O. The OIS driver  120  may move the image sensor  111  in a first direction and a second direction perpendicular to the optical axis O. The first direction and the second direction may intersect each other. For example, the OIS driver  120  may move the movable body  110  in the X direction and/or the Y direction perpendicular to the Z-axis, and accordingly, may correct shake in the X-direction and/or the Y-direction. 
     In an example, the OIS driver  120  may rotate the movable body  110  with respect to the fixed body based on an axis parallel to the optical axis O. The OIS driver  120  may correct rotation of the camera module  1  or the electronic device in which the image sensor  111  is mounted, based on an axis parallel to the optical axis O. 
     In one or more examples, the direction in which the imaging plane  111   a  of the image sensor  111  faces may be referred to as an optical axis O direction. For example, the movable body  110  may move in a direction perpendicular to the optical axis O with respect to the fixed body  130 . In the drawings of the one or more examples, the optical axis ( 0 ) is illustrated parallel to the Z axis, and thus the Z direction indicates a direction parallel to the optical axis ( 0 ). In addition, the X direction or Y direction indicates a direction perpendicular to the optical axis ( 0 ). For example, in one or more examples, moving the movable body  110  in the X direction may be understood as moving the movable body  110  in a direction perpendicular to the optical axis O. In another example, it may be understood that the driving yoke  121  and the driving coil  122  opposing each other in the X direction indicates that the driving yoke  121  and the driving coil  122  face each other in a direction perpendicular to the optical axis O. Additionally, the X direction or the Y direction is an example of two directions perpendicular to the optical axis O and intersecting each other, and in the one or more examples, the X direction and the Y direction may be understood as two directions perpendicular to the optical axis O and intersecting each other. 
     2.1.1. PCB Spring 
     In an example, the sensor shifting module  100  may include a substrate  140  that mechanically connects the movable body  110  to the fixed body  130 . The substrate  140  may couple the movable body  110  to the fixed body  130  to be movable with respect to the fixed body  130  in a direction perpendicular to the optical axis O. A portion of the substrate  140  may be deformed according to the movement of the movable body  110  with respect to the fixed body  130 . For example, a portion of the substrate  140  may be flexible. When the substrate  140  is deformed, a restoring force is generated in the substrate  140 , and this restoring force may return the movable body  110  to an original position thereof. The movable body  110  in the equilibrium state moves with respect to the fixed body  130  as a current is applied to the driving coil  122 , and when the current does not flow in the driving coil  122 , the movable body  110  may return to the original position by the substrate  140 . 
       FIG.  3    illustrates a top view of the substrate  140  on which the image sensor  111  is mounted, in accordance with one or more embodiments. Referring to  FIGS.  2  and  3   , the substrate  140  may include a floating part  141  on which the sensor substrate  112  is seated, and a fixed part  142  fixed to the fixed body  130 . The sensor substrate  112  and the floating part  141  may be electrically connected to each other through solder balls at corresponding contact points P 1  and P 2 . 
     While the movable body  110  (or the image sensor  111 ) moves with respect to the fixed body  130 , the floating part  141  moves with respect to the fixed part  142 . The substrate  140  may include a support part  143  connecting the floating part  141  and the fixed part  142  to each other. The support part  143  may be deformed at least partially according to a relative movement between the floating part  141  and the fixed body  130 . In an example, the support part  143  may be formed of a flexible substrate. The flexible substrate may be provided in a form in which a conductive pattern (or an electric trace  145 ) is formed inside a film formed of a polyimide material. 
     In an example, the substrate  140  may include a plurality of bridge elements  144  connecting the floating part  141  and the fixed part  142 . The plurality of bridge elements  144  may constitute at least a portion of the support part  143 . The plurality of bridge elements  144  are formed of a flexible material, and may be deformed when the floating part  141  moves with respect to the fixed part  142 . When the movable body  110  moves with respect to the fixed body  130 , the floating part  141  may move with respect to the fixed part  142 , and the bridge elements  144  may be deformed. The restoring force generated while the bridge elements  144  are deformed may return the movable body  110  or the floating part  141  to the original position thereof. The plurality of bridge elements  144  may respectively contain at least one electric trace  145 . For example, the plurality of bridge elements  144  may mechanically and electrically connect the floating part  141  (or the movable body  110 ) to the fixed part  142  (or the fixed body  130 ). For example, the bridge elements  144  support the image sensor  111  and may function as a passage through which a signal of the image sensor  111  is transmitted. 
     In an example, the substrate  140  may include a guide  146  disposed between the floating part  141  and the fixed part  142 . For example, the guide  146  may be provided in the form of a frame surrounding the floating part  141 . The fixed part  142 , the guide  146 , and the floating part  141  may be connected via the bridge elements  144 . For example, the substrate  140  may include a first bridge  147  extending from the floating part  141  to the guide  146 , and a second bridge  148  extending from the guide  146  to the fixed part  142 . The first bridge  147  and the second bridge  148  may extend in a direction perpendicular to the optical axis O. The first bridge  147  and the second bridge  148  may extend in directions intersecting each other. For example, the first bridge  147  may extend in the Y direction, and the second bridge  148  may extend in the Z direction. 
     The first bridge  147  and the second bridge  148  may each include one or more bridge elements  144 . In  FIG.  3   , the first bridge  147  includes four bridge elements  144  extending in the X direction, and the second bridge  148  includes four bridge elements  144  extending in the Y direction. The substrate  140  of  FIG.  3    has an illustrative shape, and the shape of the support part  143  connecting the floating part  141  and the fixed part  142  may be various. For example, the support part  143  may be comprised of the plurality of bridge elements  144  extending directly from the floating part  141  to the fixed part  142 . As another example, the first bridge  147  or the second bridge  148  may include five bridge elements  144 . The number of bridge elements  144  constituting the first bridge  147  or the second bridge  148  may be as many as the number corresponding to the number of terminals of the image sensor  111 . 
     The substrate  140  may include the electric trace  145  that transmits a signal of the image sensor  111 . The plurality of bridge elements  144  constituting the support part  143  embed the electric trace  145 . The image sensor  111  is mounted on the sensor substrate  112 , and the sensor substrate  112  is electrically connected to the fixed part  142  of the substrate  140 . The electric trace  145  may extend from each of the contact points P 2  formed in the floating part  141 . The electric trace  145  may extend through bridge element  144  to fixed part  142 . The electric trace  145  extending to the fixed part may be electrically connected to another substrate or electronic component. 
     On the other hand,  FIG.  3    schematically illustrates the electric trace  145  formed on the substrate  140 , and only the electric trace  145  extending from some contact points is illustrated for convenience of description. 
     2.1.2. Position Sensor 
     Referring to  FIG.  2   , in an example, the OIS driver  120  may include a position sensor  127  that may measure how much the movable body  110  moves in a direction perpendicular to the optical axis O, or how much the movable body rotates based on an axis parallel to the optical axis O. The position sensor  127  may be, as examples, a Hall sensor or a magnetoresistance sensor. 
     The OIS driver  120  may include a sensing magnet  124  that moves together with the movable body  110  and faces the position sensor  127 . The position sensor  127  may be disposed to face the sensing magnet  124 . For example, the position sensor  127  may be disposed on the base  131 , and the sensing magnet  124  may be disposed on the substrate to face the position sensor  127  in the optical axis O direction (e.g., in the Z direction). As another example, the position sensor  127  may be disposed on the substrate, and the sensing magnet  124  may be disposed on the base  131 . The position sensor  127  and the sensing magnet  124  may be provided in two or more pairs. 
     2.2. Actuator 
     Referring to  FIG.  2   , in an example, the OIS driver  120  may include a driving coil  122  coupled to one of the movable body  110  or the fixed body  130 , and a driving yoke  121  coupled to the other one of the movable body  110  or the fixed body  130 . For example, referring to  FIG.  2   , in an example, the driving coil  122  and the driving yoke  121  may be coupled to the base  131  and the sensor holder  113 , respectively. The driving yoke  121  and the driving coil  122  may face each other in a direction perpendicular to the optical axis O. The electromagnetic interaction between the driving yoke  121  and the driving coil  122  causes the movable body  110  to move in a direction perpendicular to the optical axis O with respect to the fixed body  130 . In addition, electromagnetic interaction between the driving yoke  121  and the driving coil  122  may rotate the movable body  110  with respect to the fixed body  130  about an axis parallel to the optical axis O. 
     In an example, the OIS driver  120  may further include a yoke  123  disposed on one side of the coil. The yoke  123  allows the magnetic field generated in the coil to be concentrated only in a direction toward the driving yoke  121 . Since the yoke  123  is disposed on one side of the driving coil  122 , the magnetic field generated by the driving coil  122  may be prevented from affecting other electronic components, or may significantly reduce the magnetic field from affecting other electronic components. 
     In one or more examples, the driving coil  122  and the driving yoke  121  are consistently described as being coupled to the fixed body  130  and the movable body  110 , respectively. However, this is only an example, and in another example, the driving coil  122  and the driving yoke  121  may be coupled to the movable body  110  and the fixed body  130 , respectively. For example, the driving coil  122  and the driving yoke  121  may be coupled to the sensor holder  113  and the base  131 , respectively. 
     An air gap may be formed between the driving coil  122  and the driving yoke  121 . Alternatively, the space between the driving coil  122  and the driving coil  122  may be an air gap. For example, there may be no other member (e.g., a magnet) between the driving coil  122  and the driving yoke  121 . The driving coil  122  and the driving yoke  121  directly face each other with an air gap therebetween. 
       FIG.  2    illustrates components of the OIS driver  120 , and the one or more examples are not limited by the structure of  FIG.  2   . 
     2.2.1. Reluctance 
     In an example, the OIS driver  120  may not include a permanent magnet. In an example, when no current flows in the driving coil  122 , the magnetic field due to the driving yoke  121  may be zero or a very small level. Accordingly, the magnetic field caused by the OIS driver  120  itself may be prevented or significantly reduced from affecting other electronic components (e.g., other electronic components inside the camera module  1 , or other electronic components inside another camera module  1 ). 
     In an example, the driving yoke  121  may be formed of a soft magnetic material. A soft magnetic material has low coercive force and is magnetized when exposed to a magnetic field, but loses magnetism or may have a relatively low level of magnetism when the magnetic field disappears. 
     When a current is applied to the driving coil  122 , the driving yoke  121  is magnetized, thereby generating a reluctance force between the driving coil  122  and the driving yoke  121 . An attractive force is generated in a direction in which the driving yoke  121  and the driving coil  122  face each other, which causes the movable body  110  to move with respect to the fixed body  130  in the corresponding direction. For example, referring to  FIG.  4   , when current is applied to a first unit driving part  120 - 1  and a second unit driving part  120 - 2 , an attractive force is generated between the driving coil  122  and the driving yoke  121  constituting the unit driving parts  120 - 1  and  120 - 2 , which may move the movable body  110  in the −X direction. Conversely, when current is applied to a third unit driving part  120 - 3  and a fourth unit driving part  120 - 4 , attractive force is generated between the driving coil  122  and the driving yoke  121  constituting the unit driving parts  120 - 3  and  120 - 4 , which may move the movable body  110  in the +X direction. 
     2.2.2. Array (Translation+Rolling) 
       FIG.  4    is a top view of the OIS driver  120 , in accordance with one or more embodiments. 
     The OIS driver  120  may include a plurality of unit driving parts  120 - 1 ,  120 - 2 ,  120 - 3 ,  120 - 4 ,  120 - 5 ,  120 - 6 ,  120 - 7 , and  120 - 8 . The unit driving parts  120 - 1 ,  120 - 2 ,  120 - 3 ,  120 - 4 ,  120 - 5 ,  120 - 6 ,  120 - 7 , and  120 - 8  may each include one driving yoke  121  and one driving coil  122  facing each other. The driving yoke  121  and the driving coil  122  may be mounted to face each other on the movable body  110  or the fixed body  130 . It may be understood that the unit driving parts  120 - 1 ,  120 - 2 ,  120 - 3 ,  120 - 4 ,  120 - 5 ,  120 - 6 ,  120 - 7 , and  120 - 8  further include a yoke  123  disposed on one side of the driving coil  122 . 
     In an example, the OIS driver  120  may include at least one unit driving part disposed in the −X direction and the +X direction of the movable body  110 , respectively, to correct the shake in the X direction. For example, referring to  FIG.  4   , the OIS driver  120  may include a first unit driving part  120 - 1 , a second unit driving part  120 - 2 , a third unit driving part  120 - 3 , and a fourth unit driving part  120 - 4 . The first unit driving part  120 - 1  and the second unit driving part  120 - 2  are disposed in the −X direction of the movable body  110 , and may move the movable body  110  in the −X direction when a current is applied. The third unit driving part  120 - 3  and the fourth unit driving part  120 - 4  are disposed in the +X direction of the movable body  110 , and may move the movable body  110  in the +X direction when current is applied. 
     The first unit driving part  120 - 1  and the third unit driving part  120 - 3  may be arranged in a first direction (e.g., X direction) perpendicular to the optical axis O. Additionally, the second unit driving part  120 - 2  and the fourth unit driving part  120 - 4  may be arranged in the first direction. For example, when viewed in the first direction, the first unit driving part  120 - 1  and the third unit driving part  120 - 3  overlap each other, and the second unit driving part  120 - 2  and the fourth unit driving part  120 - 4  overlap each other. 
     In an example, the OIS driver  120  may include at least one unit driving part disposed in the −X direction and the +X direction of the movable body  110 , respectively, to correct the shake in the X direction. For example, the OIS driver  120  may include a fifth unit driving part  120 - 5 , a sixth unit driving part  120 - 6 , a seventh unit driving part  120 - 7 , and an eighth unit driving part  120 - 8 . The fifth unit driving part  120 - 5  and the sixth unit driving part  120 - 6  are disposed in the +Y direction of the movable body  110 , and may move the movable body  110  in the +Y direction when current is applied. The seventh unit driving part  120 - 7  and the eighth unit driving part  120 - 8  are disposed in the −Y direction of the movable body  110 , and may move the movable body  110  in the −Y direction when current is applied. 
     The fifth unit driving part  120 - 5  and the seventh unit driving part  120 - 7  may be arranged in a second direction (e.g., a Y direction) perpendicular to the optical axis O. Additionally, the sixth unit driving part  120 - 6  and the eighth unit driving part  120 - 8  may be arranged in the second direction. For example, when viewed in the second direction, the fifth unit driving part  120 - 5  and the seventh unit driving part  120 - 7  overlap each other, and the sixth unit driving part  120 - 6  and the eighth unit driving part  120 - 8  overlap each other. 
     In an example, the movable body  110  has four side surfaces  113   b - 1 ,  113   b - 2 ,  113   b - 3 , and  113   b - 4  that form a quadrangle, and a driving coil  122  or a driving coil  121  may be disposed adjacently to both ends of each of the four side surfaces  113   b - 1 ,  113   b - 2 ,  113   b - 3  and  113   b - 4 . The first unit driving part  120 - 1  and the second unit driving part  120 - 2  may be disposed on the first side surface  113   b - 1  of the movable body  110 , and may be spaced apart from each other. For example, the first side surface  113   b - 1  may face the −X direction, and the first unit driving part  120 - 1  and the second unit driving part  120 - 2  may be spaced apart from each other in the Y direction. The first unit driving part  120 - 1  and the second unit driving part  120 - 2  may be disposed adjacently to both ends of the first side surface  113   b - 1 , respectively. When viewed in the X direction, the optical axis O (or the image sensor  111 ) may be positioned between the first unit driving part  120 - 1  and the second unit driving part  120 - 2 . Accordingly, when a current is applied to either the first unit driving part  120 - 1  or the second unit driving part  120 - 2 , a Z-axis moment may be generated in the movable body  110 , which causes the movable body  110  to be rotated with respect to the fixed body about the Z axis. 
     The third unit driving part  120 - 3  and the fourth unit driving part  120 - 4  are disposed on the second side surface  113   b - 2  of the movable body  110  and are spaced apart from each other. The second side surface  113   b - 2  and the first side surface  113   b - 1  face opposite directions. For example, the second side surface  113   b - 2  may face the +X direction, and the third unit driving part  120 - 3  and the fourth unit driving part  120 - 4  may be spaced apart from each other in the Y direction. The third unit driving part  120 - 3  and the fourth unit driving part  120 - 4  may be disposed close to both ends of the second side surface  113   b - 2 , respectively. When viewed in the X direction, the optical axis O (or the image sensor  111 ) may be positioned between the third unit driving part  120 - 3  and the fourth unit driving part  120 - 4 . Accordingly, when a current is applied to either the third unit driving part  120 - 3  or the fourth unit driving part  120 - 4 , a Z-axis moment may be generated in the movable body  110 , which causes the movable body  110  to be rotated with respect to the fixed body about the Z axis. 
     The fifth unit driving part  120 - 5  and the sixth unit driving part  120 - 6  are disposed on the third side surface  113   b - 3  of the movable body  110  and are spaced apart from each other. The fifth unit driving part  120 - 5  and the sixth unit driving part  120 - 6  may be spaced apart from each other in the X direction. The fifth unit driving part  120 - 5  and the sixth unit driving part  120 - 6  may be disposed close to both ends of the third side surface  113   b - 3 , respectively. When viewed in the Y direction, the optical axis O (or the image sensor  111 ) may be positioned between the fifth unit driving part  120 - 5  and the sixth unit driving part  120 - 6 . Accordingly, when a current is applied to one of the fifth unit driving part  120 - 5  or the sixth unit driving part  120 - 6 , a Z-axis moment may be generated in the movable body  110 , which causes the movable body  110  to be rotated with respect to the fixed body about the Z axis. 
     The seventh unit driving part  120 - 7  and the eighth unit driving part  120 - 8  are disposed on the fourth side surface  113   b - 4  of the movable body  110 , and are spaced apart from each other. The fourth side surface  113   b - 4  faces opposite directions to the third side surface  113   b - 3 . The seventh unit driving part  120 - 7  and the eighth unit driving part  120 - 8  may be spaced apart from each other in the X direction. The seventh unit driving part  120 - 7  and the eighth unit driving part  120 - 8  may be disposed close to both ends of the fourth side surface  113   b - 4 . When viewed in the Y direction, the optical axis O (or the image sensor  111 ) may be positioned between the seventh unit driving part  120 - 7  and the eighth unit driving part  120 - 8 . Accordingly, when a current is applied to one of the seventh unit driving part  120 - 7  or the eighth unit driving part  120 - 8 , a Z-axis moment may be generated in the movable body  110 , which causes the movable body  110  to be rotated with respect to the fixed body about the Z axis. 
     The OIS driver  120  may include a plurality of unit driving parts to correct rotation with respect to an axis parallel to the optical axis O. The OIS driver  120  may include at least one unit driving part generating a Z-axis moment in the movable body  110 . 
     For example, when current is applied to at least one of the first unit driving part  120 - 1 , the fourth unit driving part, the sixth unit driving part  120 - 6 , or the seventh unit driving part, a moment in the +Z direction (direction coming out of the ground) may be generated in the movable body  110  by the attractive force between the driving yoke and the driving coil. For another example, when current is applied to at least one of the second unit driving part  120 - 2 , the third unit driving part, the fifth unit driving part, or the eighth unit driving part, a moment in the −Z direction (the direction entering the ground) may occur in the movable body  110  by the attractive force between the driving yoke and the driving coil. 
     In an example, the unit driving part may be disposed adjacent to a corner of the movable body  110 . The movable body  110  includes a first side surface  113   b - 1  and a third side surface  113   b - 3  extending in different directions from a first corner  113   a - 1 , respectively. The first unit driving part  120 - 1  is disposed on the first side surface  113   b - 1 , to be close to the first corner  113   a - 1 , and the fifth unit driving part is disposed on the third side surface  113   b - 3 , to be close to the first corner  113   a - 1 . The movable body  110  includes the first side surface  113   b - 1  and the fourth side surface  113   b - 4  extending in different directions from a second corner  113   a - 2 , respectively. The second unit driving part  120 - 2  is disposed on the first side surface  113   b - 1 , to be close to the second corner  113   a - 2 , and the seventh unit driving part  120 - 2  is disposed on the fourth side surface  113   b - 4 , to be close to the second corner  113   b - 4 . The movable body  110  includes the second side surface  113   b - 2  and the third side surface  113   b - 3  extending in different directions from the third corner  113   a - 3 , respectively. The third unit driving part  120 - 3  is disposed on the second side surface  113   b - 2 , to be close to the third corner  113   a - 3 , and the sixth unit driving part  120 - 6  is disposed on the third side surface  113   b - 3 , to be close to the third corner  113   a - 3 . The movable body  110  includes the second side surface  113   b - 2  and the fourth side surface  113   b - 4  extending in different directions from the fourth corner  113   a - 4 , respectively. The fourth unit driving part  120 - 4  is disposed on the second side surface  113   b - 2 , to be close to the fourth corner  113   a - 4 , and the eighth unit driving part  120 - 4  is disposed on the fourth side surface  113   b - 4 , to be close to the fourth corner  113   a - 4 . 
     In one or more examples, being disposed close to the corner may indicate that the unit driving part is spaced apart from the optical axis O when viewed from the side. For example, when viewed in the X direction, the first unit driving part  120 - 1  may be disposed at a position away from the optical axis O in the +Y direction. Alternatively, when viewed in the Y direction, the fifth unit driving part  120 - 5  may be disposed at a position away from the optical axis O in the −X direction. Accordingly, the unit driving part may generate a moment in the direction parallel to the optical axis O in the movable body  110 . 
     The arrangement or number of the unit driving parts illustrated in  FIG.  4    is merely an example, and the one or more examples are not limited thereto. For example, additional unit driving parts other than the unit driving parts illustrated in  FIG.  4    may be provided. As another example, a portion of the unit driving parts illustrated in  FIG.  4    may be omitted. 
     Referring to  FIG.  4   , the driving yoke  121  may be configured so that it does not interfere with the corresponding driving coil  122  when the movable body  110  rotates. In an example, a surface of the driving yoke  121 , opposite to the driving coil  122 , may be convex. The thickness of the driving yoke  121  may decrease from a central portion  121   a  to both ends  121   b . Since the driving yoke  121  is provided to be convex, the rotation range of the movable body  110  may be increased. 
     For example, the opposite surface of the driving yoke  121  to the driving coil  122  may include an inclined surface  121   c  extending from the central portion  121   a  to both ends  121   b . Referring to the enlarged view of the upper right of  FIG.  4   , the driving yoke  121  and the driving coil  122  face in the Y direction perpendicular to the optical axis O, and a distance d 1  between the central portion  121   a  of the driving yoke  121  and the driving coil  122  in the Y direction may be shorter than a distance d 2  between an end  121   b  of the driving yoke  121  and the driving coil  122  in the Y direction. 
     2.3. Movement 
     2.3.1. Translation 
       FIGS.  5 A to  5 D  illustrate the movement of the movable body  110  based on the OIS driver  120  of  FIG.  4   . 
     Referring to  FIG.  5 A , when current is applied to the first unit driving part  120 - 1  and the second unit driving part  120 - 2 , a force in the direction of the arrow is applied to the movable body  110 , which causes the movable body  110  to move in the −X direction. Referring to  FIG.  5 B , when a current is applied to the third unit driving part  120 - 3  and the fourth unit driving part  120 - 4 , a force in the direction of the arrow acts on the movable body  110 , which causes the movable body  110  to move in the +X direction. Referring to  FIG.  5 C , when current is applied to the fifth unit driving part  120 - 5  and the sixth unit driving part  120 - 6 , a force in the direction of the arrow is applied to the movable body  110 , which causes the movable body  110  to move in the +Y direction. Referring to  FIG.  5 D , when a current is applied to the seventh unit driving part  120 - 7  and the eighth unit driving part  120 - 8 , a force in the direction of the arrow acts on the movable body  110 , which causes the movable body  110  to move in the −Y direction. 
     2.3.2. Rolling 
       FIGS.  6  and  7    illustrate rotation of the movable body  110  by the OIS driver  120  of  FIG.  4   . 
     Referring to  FIG.  6   , when a current is applied to the first unit driving part  120 - 1 , the fourth unit driving part, the sixth unit driving part  120 - 6 , or the seventh unit driving part, the force of the respective driving parts in the direction of the arrow generates a +Z-direction moment in the movable body  110 , which may rotate the movable body  110  counterclockwise with respect to the fixed body. 
     Referring to  FIG.  7   , when current is applied to the second unit driving part  120 - 2 , the third unit driving part, the fifth unit driving part, or the eighth unit driving part, the force of the respective driving parts in the direction of the arrow generates −Z direction moment in the movable body  110 , which may rotate the movable body  110  clockwise with respect to the fixed body. 
     2.5. Flexible Substrate Deformation 
       FIGS.  8 A to  8 D  illustrate deformation of the substrate  140  according to the movement of the movable body  110 , in accordance with one or more embodiments. 
     Referring to  FIG.  8 A , when the movable body  110  moves in the −X direction, the floating part  141  of the substrate  140  also moves in the −X direction, and therefore, the first bridge  147  connecting the guide  146  and the fixed part  142  to each other may be deformed. Since the bridge elements  144  constituting the first bridge  147  have elasticity, the deformed first bridge  147  provides a restoring force to return the floating part  141  to the direction (e.g., the +X direction) opposite to the moving direction. Accordingly, when no current is applied to the OIS driver  120 , the floating part  141  moves in the −X direction. 
     Referring to  FIG.  8 B , when the movable body  110  moves in the +X direction, the floating part  141  of the substrate  140  also moves in the +X direction, and thus, the first bridge  147  connecting the guide  146  and the fixed part  142  to each other is deformed. Since the bridge elements  144  constituting the first bridge  147  have elasticity, the deformed first bridge  147  provides a restoring force to return the floating part  141  to the direction (e.g., the −X direction) opposite to the moving direction. 
     Referring to  FIG.  8 C , when the movable body  110  moves in the +Y direction, the floating part  141  of the substrate  140  also moves in the +Y direction, and thus, the second bridge  148  connecting the guide  146  and the fixed part  142  is deformed. Since the bridge elements  144  constituting the second bridge  148  have elasticity, the deformed second bridge  148  provides a restoring force to return the floating part  141  to the direction (e.g., the −Y direction) opposite to the moving direction. 
     Referring to  FIG.  8 D , when the movable body  110  moves in the −Y direction, the floating part  141  of the substrate  140  also moves in the −Y direction, and thus, the second bridge  148  connecting the guide  146  and the fixed part  142  is deformed. Since the bridge elements  144  constituting the second bridge  148  have elasticity, the deformed second bridge  148  provides a restoring force to return the floating part  141  to the direction (e.g., the +Y direction) opposite to the moving direction. 
     Although the rotation of the movable body  110  is not described in  FIGS.  8 A to  8 B , the substrate may provide a restoring force in the opposite direction according to the rotation of the movable body  110 . For example, when the movable body  110  rotates counterclockwise as illustrated in  FIG.  6   , the bridge elements of the substrate are deformed to provide a clockwise restoring force to the movable body  110 . When the movable body  110  rotates in the clockwise direction as illustrated in  FIG.  7   , the bridge elements of the substrate are deformed to provide a counterclockwise restoring force to the movable body  110 . 
     2.6. Mover Change 
       FIGS.  9 A and  9 B  illustrate a sensor holder  213  in a different form from that of  FIG.  2   . 
     Referring to  FIG.  9 A , the sensor holder  213  may be disposed on the sensor substrate  112 . In an example, the sensor holder  213  includes a plate  213   a  disposed on the sensor substrate  112 , and an extension  213   b  that extends downward (e.g., in the −Z direction) from the edge of the plate  213   a . The extension  213   b  faces the driving coil (e.g., the driving coil  122  of  FIG.  2   ) of the OIS driver  120 , and the driving yoke (e.g., the driving yoke  121  of  FIG.  2   ) of the OIS driver  120  may be seated on the extension  213   b . In another example, the driving yoke is mounted on the fixed body  130  and the driving coil may be mounted on the sensor holder  213 . In this example, the driving coil and/or the yoke (e.g., the yoke  123  in  FIG.  2   ) may be seated on the extension  213   b . Compared with the sensor holder  213  of  FIG.  2   , the sensor holder  213  of  FIG.  9 A  may be more advantageous in avoiding interference with a solder ball connecting the sensor substrate  112  and the substrate  140 . Additionally, when the sensor holder  213  is disposed on the upper side of the sensor substrate  112 , the thickness of the sensor holder  213  may be relatively freely increased, which may improve the mechanical rigidity of the sensor holder  213 . 
     Referring to  FIG.  9 A , the image sensor  111  may be electrically connected to the sensor substrate  112  through conductive vias. 
     Referring to  FIG.  9 B , the sensor holder  313  may be disposed on the sensor substrate  112 . In an example, the sensor holder  313  may include a plate  313   a  disposed on the sensor substrate  112 , and an extension  313   b  that extends downward (e.g., in the −Z direction) from the edge of the plate  313   a . The extension  313   b  faces the driving coil (e.g., the driving coil  122  of  FIG.  2   ) of the OIS driver  120 , and the driving yoke (e.g., the driving yoke  121  of  FIG.  2   ) of the OIS driver  120  may be seated on the extension  313   b . In an example, the driving yoke may be mounted on the fixed body  130  and the driving coil may be mounted on the sensor holder  313 . In this example, the driving coil and/or the yoke (e.g., the yoke  123  in  FIG.  2   ) may be seated on the extension  313   b . Compared with the sensor holder  313  of  FIG.  2   , the sensor holder  313  of  FIG.  9 B  may be more advantageous in avoiding interference with the solder ball connecting the sensor substrate  112  and the substrate  140 . Additionally, when the sensor holder  313  is disposed on the upper side of the sensor substrate  112 , the thickness of the sensor holder  313  may be relatively freely increased, which may improve the mechanical rigidity of the sensor holder  313 . 
     Referring to  FIG.  9 B , the image sensor  111  may be directly mounted on the sensor substrate  112 . Accordingly, the sensor holder  313  may include a through portion  313   c  in a portion corresponding to the image sensor  111 . The image sensor  111  is seated on the sensor substrate  112 , and a terminal of the image sensor  111  and a terminal of the sensor substrate  112  may be connected to each other through wire bonding. 
     As set forth above, according to an example, the camera may provide an effective optical image stabilization operation even with a small amount of power. Alternatively, in an example, the effect of a magnetic field of an actuator driving the image sensor on an electronic component disposed outside the camera may be eliminated or significantly reduced.
