Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Application No. PCT/KR2021/018358 filed on Dec. 6, 2021, which claims priority to Korean Patent Application No. 10-2021-0002834 filed on Jan. 8, 2021, the disclosures of which are herein incorporated by reference in their entirety. 
    
    
     BACKGROUND 
     1. Field 
     Various embodiments of the disclosure described herein relate to a camera module and an electronic device including the same. 
     2. Description of Related Art 
     A mobile electronic device, such as a smartphone, may include a camera module. The camera module may include lenses, a lens barrel surrounding the lenses, and an image sensor. The camera module may receive light reflected from an external subject. The light reflected from the subject may travel into the lens barrel, may pass through the lenses, and may travel to the image sensor. The image sensor may convert the received light signal into a related electrical signal. 
     The camera module may provide an auto focus (AF) function of adjusting a focus by moving the lenses in the direction of the optical axis. The auto focus function may be automatically performed by using a sensor, or may be performed by selection of a user. 
     When the electronic device and/or the camera module is in an unpowered state, the lens assembly including the lenses may fail to remain at a fixed position and may move in the camera housing. The movement of the lens assembly may increase a risk of damage to the lenses and may cause deterioration in image quality. 
     Embodiments of the disclosure provide a camera module for limiting a movement range of a lens assembly and reducing noise caused by collision of components of the camera module when the camera module and/or an electronic device is in an unpowered state, and an electronic device including the camera module. 
     The technical problems to be solved by the disclosure are not limited to the aforementioned problems, and any other technical problems not mentioned herein will be clearly understood from the following description by those skilled in the art to which the disclosure pertains. 
     SUMMARY 
     A camera module according to an embodiment of the disclosure includes a camera housing, a lens assembly, at least part of which is accommodated in the camera housing, the lens assembly including a lens, in which the lens assembly moves along a direction of an optical axis of the lens inside the camera housing, and a stopper member coupled to the inside of the camera housing and at least part of the stopper member limits a movement range of the lens assembly in the direction of the optical axis. The stopper member includes a first stopper member to limit the movement range of the lens assembly in a first optical axis direction and a second stopper member to limit the movement range of the lens assembly in a second optical axis direction opposite to the first optical axis direction, and the first stopper member and the second stopper member are configured to provide damping when the lens assembly makes contact with the first stopper member and the second stopper member. 
     A camera module according to an embodiment of the disclosure includes a camera housing including a light receiving area on which external light is incident, in which an image sensor is disposed on a side of the camera housing, a lens assembly that is accommodated in the camera housing and that includes a lens and moves in a direction of an optical axis of the lens inside the camera housing, a first reflective member that is accommodated in the camera housing and that directs the external light incident through the light receiving area toward the lens, a second reflective member that is disposed in the camera housing to face the first reflective member with the lens assembly therebetween and that directs the external light passing through the lens toward the image sensor, a support member that is coupled to the lens assembly to move together with the lens assembly and that extends toward the second reflective member, and a damping member that is disposed on a sidewall of the camera housing and that makes contact with a portion of the support member as the lens assembly moves in the direction of the optical axis. 
     The electronic device according to the various embodiments of the disclosure may limit a movement range of the lens assembly when power is not applied to the electronic device or the camera module, thereby preventing damage to the camera module. 
     Furthermore, the electronic device according to the various embodiments of the disclosure may be configured such that the structure limiting a movement range of the lens assembly includes the stopper and/or the damper. Accordingly, the electronic device may absorb or dissipate an impact caused by collision of components of the camera module and may reduce noise.

     In another embodiment, the housing  110  may refer to a structure that forms some of the first surface  110 A, the second surface  110 B, and the third surface  110 C. 
     In an embodiment, the first surface  110 A may be formed by a front plate  102 , at least a portion of which is substantially transparent (e.g., a glass plate including various coating layers, or a polymer plate). The second surface  110 B may be formed by a back plate  111  that is substantially opaque. The back plate  111  may be formed of, for example, coated or colored glass, ceramic, polymer, metal (e.g., aluminum, stainless steel (STS), or magnesium), or a combination of at least two of the aforementioned materials. The third surface  110 C may be formed by a side bezel structure (or a side member)  118  that is coupled with the front plate  102  and the back plate  111  and that contains metal and/or polymer. 
     In another embodiment, the back plate  111  and the side bezel structure  118  may be integrally formed with each other and may contain the same material (e.g., a metallic material such as aluminum). 
     In the illustrated embodiment, the front plate  102  may include two first areas  110 D that curvedly and seamlessly extend from partial areas of the first surface  110 A toward the back plate  111 . The first areas  110 D may be located at opposite long edges of the front plate  102 . 
     In the illustrated embodiment, the back plate  111  may include two second areas  110 E that curvedly and seamlessly extend from partial areas of the second surface  110 B toward the front plate  102 . The second areas  110 E may be located at opposite long edges of the back plate  111 . 
     In another embodiment, the front plate  102  (or the back plate  111 ) may include only one of the first areas  110 D (or the second areas  110 E). Furthermore, in another embodiment, the front plate  102  (or the back plate  111 ) may not include a part of the first areas  110 D (or the second areas  110 E). 
     In an embodiment, when viewed from a side of the electronic device  100 , the side bezel structure  118  may have a first thickness (or width) at sides (e.g., short sides) not including the first areas  110 D or the second areas  110 E and may have a second thickness at sides (e.g., long sides) including the first areas  110 D or the second areas  110 E, the second thickness being smaller than the first thickness. 
     In an embodiment, the electronic device  100  may include at least one of a display  101 , an audio module  103 ,  104 , and  107  (e.g., an audio module  570  of  FIG. 19 ), a sensor module (not illustrated) (e.g., a sensor module  576  of  FIG. 19 ), camera modules  105   112 , and  113  (e.g., a camera module  580  of  FIG. 19 ), key input devices  117  (e.g., an input module  550  of  FIG. 19 ), a light emitting element (not illustrated), or a connector hole  108  (e.g., a connecting terminal  578  of  FIG. 19 ).

     In an embodiment, the second camera module  112  may be disposed on the printed circuit board  150  such that a lens receives external light through a camera area  184  of the back plate  180  (e.g., the rear surface  110 B of  FIG. 2 ) of the electronic device  100 . For example, the lens of the second camera module  112  may be visually exposed through the camera area  184 . In an embodiment, the second camera module  112  may be disposed in at least part of an inner space formed in the housing (e.g., the housing  110  of  FIGS. 1 and 2 ) of the electronic device  100  and may be electrically connected to the printed circuit board  150  through a connecting member (e.g., a connector). 
     In an embodiment, the camera area  184  may be formed in a surface (e.g., the rear surface  110 B of  FIG. 2 ) of the back plate  180 . In an embodiment, the camera area  184  may be formed to be at least partially transparent such that external light is incident on the lens of the second camera module  112 . In an embodiment, at least part of the camera area  184  may protrude to a predetermined height from the surface of the back plate  180 .

       FIG. 4  is a perspective view of a camera module  200  according to an embodiment.  FIG. 5  is an exploded perspective view of the camera module  200  according to an embodiment. 
     Referring to  FIGS. 4 and 5 , the camera module  200  according to an embodiment (e.g., the first camera module  105  or the second camera module  112  of  FIGS. 1 to 3 ) may include a camera housing  210 , a lens assembly  220 , a reflective member assembly  230 , a guide structure  250 , a stopper member  240 , a first drive member  260 , a second drive member  270 , a sensor assembly  283 , a second reflective member  291 , and a flexible circuit board  292 . 
     In an embodiment, the camera housing  210  may form at least part of the exterior of the camera module  200 . For example, the surface of the camera housing  210  may form the outer surface or the exterior of the camera module  200 . The other components of the camera module  200  may be accommodated in the camera housing  210 . 
     In an embodiment, the camera housing  210  may include a first housing  210 - 1  and a second housing  210 - 2  coupled with the first housing  210 - 1 . For example, the first housing  210 - 1  may be a lower housing or a frame, and the second housing  210 - 2  may be an upper housing or a cover. The camera housing  210  may be configured to provide a predetermined space, in which the other components of the camera module  200  are accommodated, through the coupling of the first housing  210 - 1  and the second housing  210 - 2 . For example, the first housing  210 - 1  may form the lower surface (e.g., the surface facing the −z-axis direction) of the camera module  200 , and the second housing  210 - 2  may form the upper surface (e.g., the surface facing the +z-axis direction) and the side surfaces (e.g., the surfaces facing the x-axis direction and the y-axis direction) of the camera module  200 . 
     In an embodiment, the first housing  210 - 1 , together with the second housing  210 - 2 , may form the space in which the other components of the camera module  200  are accommodated. The first housing  210 - 1  may be formed in a form that is open at the top and may have a receiving space formed therein in which the lens assembly  220 , the reflective member assembly  230 , the second reflective member  291 , and/or the guide structure  250  is disposed. For example, the receiving space of the first housing  210 - 1  may refer to a predetermined space surrounded by the bottom surface (e.g., a base  212 ) and the side surfaces (e.g., sidewalls  213 ,  214 ,  215 , and  216 ) of the first housing  210 - 1 . At least part of the receiving space may be covered by the second housing  210 - 2 . 
     According to an embodiment, the other components of the camera module  200  may be supported on, or coupled to, the first housing  210 - 1 . For example, the first housing  210 - 1  may be configured such that the lens assembly  220 , the reflective member assembly  230 , the second reflective member  291 , and the guide structure  250  are disposed in the receiving space of the first housing  210 - 1  and the flexible circuit board  292 , the sensor assembly  283 , and the stopper member  240  are disposed on the sidewalls  213 ,  214 ,  215 , and  216  of the first housing  210 - 1 . For example, the guide structure  250 , the reflective member assembly  230  (or a first reflective member  231 ), the lens assembly  220 , and the second reflective member  291  may be sequentially disposed in a first optical axis direction d in the receiving space. 
     In an embodiment, the first housing  210 - 1  may include the base  212  forming the bottom surface (e.g., the surface facing the z-axis direction) of the first housing  210 - 1  (or the camera module  200 ) and the plurality of sidewalls  213 ,  214 ,  215 , and  216  extending from the edges of the base  212  in a direction (e.g., the +z-axis direction) perpendicular to the base  212 . 
     In an embodiment, the lens assembly  220  may be disposed on the base  212  so as to be movable in the direction of an optical axis L. For example, a plurality of first balls  229  may be disposed between a lens carrier  222  of the lens assembly  220  and the base  212  to guide a movement of the lens assembly  220 . In an embodiment, the base  212  may have first recesses  217  formed therein in which the plurality of first balls  229  are disposed. For example, partial areas of the base  212  may be recessed in the −z-axis direction to form the first recesses  217 . The first recesses  217  may be formed in a shape extending in the direction of the optical axis L (e.g., the x-axis direction) by a predetermined length. For example, as many first recesses  217  as the plurality of first balls  229  may be formed. The plurality of first balls  229  may be configured to roll in the space between the lens carrier  222  and the base  212 . For example, when the lens carrier  222  moves in the direction of the optical axis L, the plurality of first balls  229  may rotate while linearly moving in the direction of the optical axis L between the lens carrier  222  and the base  212 , or may rotate in position. 
     In various embodiments, the camera module  200  may be configured to provide an auto focus (AF) function by moving the lens assembly  220  in the direction of the optical axis L by using the first drive member  260 . 
     In an embodiment, the plurality of sidewalls  213 ,  214 ,  215 , and  216  may include the first sidewall  213  parallel to the optical axis L, the second sidewall  214  facing the first sidewall  213  and parallel to the optical axis L, the third sidewall  215  facing a second optical axis direction  2  (e.g., the +x-axis direction) and connecting the first sidewall  213  and the second sidewall  214 , and the fourth sidewall  216  facing the first optical axis direction d (e.g., the −x-axis direction) and connecting the first sidewall  213  and the second sidewall  214 . For example, the third sidewall  215  may connect end portions (e.g., the end portions facing the second optical axis direction  2  or the end portions facing the +x-axis direction) of the first sidewall  213  and the second sidewall  214 , and the fourth sidewall  216  may connect end portions (e.g., the end portions facing the first optical axis direction d or the end portions facing the −x-axis direction) of the first sidewall  213  and the second sidewall  214 . For example, the third sidewall  215  and the fourth sidewall  216  may be substantially perpendicular to the first sidewall  213  and the second sidewall  214 . 
     In an embodiment, the first housing  210 - 1  may be configured such that the flexible circuit board  292  and coils  261 ,  271 , and  273  are disposed on at least some of the plurality of sidewalls  213 ,  214 ,  215 , and  216 . For example, at least some of the plurality of sidewalls  213 ,  214 ,  215 , and  216  may be surrounded by the flexible circuit board  292 , and the coils  261 ,  271 , and  273  may be disposed on at least parts of the flexible circuit board  292 . 
     In an embodiment, among the plurality of sidewalls  213 ,  214 ,  215 , and  216 , at least a part of the first sidewall  213 , the second sidewall  214 , and the third sidewall  215  may be surrounded by the flexible circuit board  292 . Opening areas  2131 ,  2132 ,  2141 ,  2142 , and  2151  may be formed in the first sidewall  213 , the second sidewall  214 , and the third sidewall  215  such that the plurality of coils  261 ,  271 , and  273  are disposed therein. The plurality of coils  261 ,  271 , and  273  may be located in the receiving space of the first housing  210 - 1  through the opening areas and may be disposed to face a plurality of magnets  262 ,  272 , and  274  corresponding thereto. For example, the first sidewall  213  may have the first opening area  2131  in which the first coil  261  is located and the second opening area  2132  in which the second coil  271  is located. The second sidewall  214  may have the third opening area  2141  in which the first coil  261  is located and the fourth opening area  2142  in which the second coil  271  is located. The third sidewall  215  may have the fifth opening area  2151  in which the third coil  273  is located. 
     In an embodiment, the sensor assembly  283  may be disposed on the second sidewall  214  of the first housing  210 - 1 . For example, a sixth opening area  2143  may be formed in the second sidewall  214 , and the sensor assembly  283  may be disposed on the second sidewall  214  such that an image sensor  281  is aligned with the sixth opening area  2143 . For example, the sensor assembly  283  may be disposed on the outside surface (e.g., the surface facing the −y-axis direction) of the second sidewall  214  such that the image sensor  281  faces toward the sixth opening area  2143 . The image sensor  281  may partially overlap the sixth opening area  2143  when the second sidewall  214  is viewed from the front with respect to  FIG. 5  (e.g., when the second sidewall  214  is viewed in the −y-axis direction). According to an embodiment, external light passing through the first reflective member  231  and a lens unit  221  may be incident on the image sensor  281  through the sixth opening area  2143  after refracted and/or reflected by the second reflective member  291 . 
     In an embodiment, the second housing  210 - 2  may be coupled to an upper portion (e.g., the +z-axis direction) of the first housing  210 - 1 . The second housing  210 - 2  may be formed in a form capable of covering at least part of the first housing  210 - 1 . For example, the second housing  210 - 2  may be coupled to the upper portion of the first housing  210 - 1  to cover the receiving space. 
     In an embodiment, the second housing  210 - 2  may have a light receiving area  211  formed therein through which the first reflective member  231  is visually exposed. For example, the light receiving area  211  may be formed in a partial area of an upper surface  210   a  (e.g., the surface facing the +z-axis direction) of the second housing  210 - 2 . For example, the light receiving area  211  may include an opening area (or a through-hole) formed in the upper surface of the second housing  210 - 2 , or may include a transparent area. External light may move into the camera housing  210  through the light receiving area  211 . The external light may be incident on the first reflective member  231 , which is disposed inside the camera housing  210 , through the light receiving area  211 . For example, the light receiving area  211  may overlap the first reflective member  231  such that the external light is incident on the first reflective member  231 . As illustrated in  FIG. 4 , at least part of the first reflective member  231  may be visually exposed outside the camera housing  210  through the light receiving area  211 . For example, at least part of the first reflective member  231  may overlap the light receiving area  211  when the upper surface  210   a  of the second housing  210 - 2  is viewed from above. 
     In an embodiment, the lens assembly  220  may be disposed inside the camera housing  210 . The lens assembly  220  may be configured to move in the direction of the optical axis L of the lens inside the camera housing  210 . For example, the lens assembly  220  may linearly move in the first optical axis direction d or the second optical axis direction  2  in the receiving space of the first housing  210 - 1 . In an embodiment, the optical axis L of the lens may be defined as the virtual axis extending in the direction in which external light passes through the lens. For example, the optical axis L may extend in substantially the x-axis direction. 
     In an embodiment, the lens assembly  220  may include the lens unit  221  and the lens carrier  222  in which at least part of the lens unit  221  is accommodated. The lens unit  221  may include one or more lenses, and at least some of the lenses may be accommodated in the lens carrier  222 . The lens unit  221  may move together with the lens carrier  222 . The lens carrier  222  may be disposed in the receiving space (e.g., on the base  212 ) of the first housing  210 - 1  so as to be movable in the direction of the optical axis L. The first magnets  262  electro-magnetically interacting with the first coils  261  may be disposed on the lens carrier  222 . For example, the lens carrier  222  may be configured to move in the direction of the optical axis L by an electro-magnetic force generated between the first coils  261  and the first magnets  262 . In another example, the lens carrier  222  may move in the direction of the optical axis in the camera housing  210  when the camera module  200  is in an unpowered state. 
     In an embodiment, the reflective member assembly  230  may be disposed inside the camera housing  210 . For example, the reflective member assembly  230  may be located in the second optical axis direction  2  with respect to the lens assembly  220 . The reflective member assembly  230  may be configured to reflect or refract external light incident through the light receiving area  211 . For example, light incident on the reflective member assembly  230  in a direction (e.g., the z-axis direction) perpendicular to the optical axis L through the light receiving area  211  may be reflected and/or refracted by the first reflective member  231  and may be incident on the lens unit  221  in the direction of the optical axis L. 
     In an embodiment, the reflective member assembly  230  may include the first reflective member  231  and a holder  232  in which at least part of the first reflective member  231  is accommodated. The first reflective member  231  may reflect and/or refract external light to direct the external light toward the lens assembly  220 . For example, the first reflective member  231  may include a mirror or prism that has an inclined surface. The first reflective member  231  may be disposed in the holder  232 . For example, the first reflective member  231  may be coupled to the holder  232  so as to move or rotate together with the holder  232 . 
     In an embodiment, the holder  232  may be configured to rotate about a virtual axis of rotation relative to the first housing  210 - 1 . The virtual axis of rotation may be substantially perpendicular to the optical axis L. For example, the holder  232  may rotate in a predetermined range about a virtual first axis of rotation (e.g., a first axis of rotation R 1  of  FIG. 9 ) substantially parallel to the z-axis. Furthermore, the holder  232  may rotate in a predetermined range about a virtual second axis of rotation (e.g., the second axis of rotation R 2  of  FIG. 9 ) substantially parallel to the y-axis. 
     In an embodiment, the guide structure  250  for guiding rotation of the reflective member assembly  230  may be coupled to the holder  232 . 
     In an embodiment, the guide structure  250  may include a first guide member  251  coupled with the holder  232  and a second guide member  252  coupled with the first guide member  251 . For example, the holder  232  may be coupled to the first guide member  251  so as to be rotatable about an axis of rotation (e.g., the first axis of rotation R 1  of  FIG. 9 ). For example, the first guide member  251  may be coupled to the second guide member  252  so as to be rotatable about an axis of rotation (e.g., the second axis of rotation R 2  of  FIG. 9 ). The holder  232  may be coupled to rotate together when the first guide member  251  rotates relative to the second guide member  252 . For example, the reflective member assembly  230  may rotate relative to the first guide member  251  when rotating about the first axis of rotation R 1  and may rotate relative to the first guide member  251  and the second guide member  252  when rotating about the second axis of rotation R 2 . The coupling relationship between the reflective member assembly  230  and the guide structure  250  will be described below with reference to  FIGS. 9 to 11 . 
     In an embodiment, the second magnets  272  electro-magnetically interacting with the second coils  271  may be disposed on the holder  232 . For example, the holder  232  may be configured to rotate about an axis of rotation parallel to the z-axis by an electro-magnetic force generated between the second coils  271  and the second magnets  272 . The third magnet  274  electro-magnetically interacting with the third coil  273  may be disposed on the first guide member  251 . For example, the first guide member  251  may be configured to rotate about an axis of rotation parallel to the y-axis by an electro-magnetic force generated between the third coil  273  and the third magnet  274 . 
     In various embodiments, the camera module  200  may rotate the reflective member assembly  230  about an axis of rotation perpendicular to the optical axis L by using the second drive member  270 , thereby providing an optical image stabilizer (OIS) function in response to external noise (e.g., a camera-shake) applied to the camera module  200 . For example, the camera module  200  may compensate for a shake of an image by changing the angle of light incident toward the lens assembly  220  by rotating the first reflective member  231  in a predetermined range. 
     In an embodiment, the stopper member  240  may limit a movement range of the lens assembly  220  in the direction of the optical axis. For example, the stopper member  240  may limit a movement of the lens assembly  220  in the direction of the optical axis by contact of at least part of the stopper member  240  with the lens assembly  220 . The stopper member  240  may be configured to provide damping for movement in the optical axis L direction of the lens assembly  220 . Furthermore, at least part of the stopper member  240  may be formed of an elastic material to absorb and/or alleviate an impact when the lens assembly  220  makes contact with the stopper member  240 . The stopper member  240  may limit the movement range of the lens assembly  220  and, at the same time, provide a damping force when in contact with the lens assembly  220 , thereby acting as a damping action. 
     In an embodiment, the stopper member  240  may include a first stopper member  241  that limits a movement of the lens assembly  220  in the first optical axis direction d and second stopper members  242  that limit a movement of the lens assembly  220  in the second optical axis direction  2 . The first stopper member  241  may be coupled to the first sidewall  213  of the first housing  210 - 1 . The second stopper members  242  may be coupled to the first sidewall  213  and/or the second sidewall  214  of the first housing  210 - 1 . For example, the first stopper member  241  may be configured to make contact with the lens assembly  220  when the lens assembly  220  moves a specified distance in the first optical axis direction {circle around ( 1 )}. The second stopper members  242  may be configured to make contact with the lens assembly  220  when the lens assembly  220  moves a specified distance in the second optical axis direction {circle around ( 2 )}. The first stopper member  241  may provide damping when the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )} and makes contact or collision. The second stopper member  242  may provide damping when the lens assembly  220  moves in the second optical axis direction {circle around ( 2 )} and makes contact or collision. The shape and function of the stopper member  240  will be described below with reference to  FIGS. 6A to 8 . 
     In an embodiment, the first drive member  260  may provide a driving force to move the lens assembly  220  in the direction of the optical axis L. The first drive member  260  may include the first coils  261  disposed on one of the camera housing  210  (e.g., the first housing  210 - 1 ) and the lens assembly  220 , and the first magnets  262  disposed on the other one of the camera housing  210  and the lens assembly  220 . According to the embodiment illustrated in  FIG. 5 , the first coils  261  may be disposed on sidewalls (e.g., the first sidewall  213  and the second sidewall  214 ) of the first housing  210 - 1 , and the first magnets  262  may be disposed on the lens carrier  222  to face the first coils  261 . However, the position of the first drive member  260  is not limited to the illustrated embodiment. In another embodiment, the first coils  261  may be disposed on the lens carrier  222 , and the first magnets  262  may be disposed on the first housing  210 - 1 . 
     In an embodiment, the camera module  200  may control the position of the lens assembly  220  in the direction of the optical axis L by controlling an electric current flowing through the first coils  261 . For example, the first magnets  262  and the first coils  261  may electro-magnetically interact with each other. For example, the first coils  261  may be located in a magnetic field formed by the first magnets  262 . In an embodiment, the processor (e.g., the processor  520  of  FIG. 19  and/or an image signal processor  660  of  FIG. 20 ) may control the direction and/or strength of the electric current passing through the first coils  261 . An electro-magnetic force (e.g., Lorentz force) may be applied to the first magnets  262  to correspond to the direction of the electric current passing through the first coils  261 . The lens assembly  220  may move in the direction of the optical axis L of the lens by the electro-magnetic force. In an embodiment, the second reflective member  291  and the image sensor  281  may be fixedly disposed in the first housing  210 - 1 , and the lens assembly  220  may move in the direction of the optical axis L between the reflective member assembly  230  and the second reflective member  291 . Accordingly, the distance between the lens assembly  220  and the second reflective member  291  may be changed, and the travel distance of light that passes through the lens and that is reflected by the second reflective member  291  and directed toward the image sensor  281  may be varied. 
     In an embodiment, the second drive member  270  may provide a driving force to rotate the reflective member assembly  230  about an axis of rotation perpendicular to the optical axis L. For example, the second drive member  270  may include the second magnets  272  and the second coils  271  for rotating the reflective member assembly  230  about an axis of rotation parallel to the z-axis, and the third magnet  274  and the third coil  273  for rotating the reflective member assembly  230  about an axis of rotation parallel to the y-axis. For example, the second magnets  272  and the second coils  271  may electro-magnetically interact with each other. For example, the third magnet  274  and the third coil  273  may electro-magnetically interact with each other. The rotary motion of the reflective member assembly  230  by the second drive member  270  will be described below with reference to  FIGS. 9 to 11 . 
     In an embodiment, the second coils  271  may be disposed on one of the camera housing  210  (e.g., the first housing  210 - 1 ) and the reflective member assembly  230 , and the second magnets  272  may be disposed on the other one of the camera housing  210  and the reflective member assembly  230 . In an embodiment, the third coil  273  may be disposed on one of the camera housing  210  and the first guide member  251 , and the third magnet  274  may be disposed on the other one of the camera housing  210  and the first guide member  251 . According to the embodiment illustrated in  FIG. 5 , the second coils  271  and the third coil  273  may be disposed on sidewalls (e.g., the first sidewall  213 , the second sidewall  214 , and the third sidewall  215 ) of the first housing  210 - 1 , the second magnets  272  may be disposed on the holder  232  to face the second coils  271 , and the third magnet  274  may be disposed on the first guide member  251  to face the third coil  273 . However, the position of the second drive member  270  is not limited to the illustrated embodiment. In another embodiment, the second magnets  272  and the third magnet  274  may be disposed on the first housing  210 - 1 , the second coils  271  may be disposed on the holder  232 , and the third coil  273  may be disposed on the first guide member  251 . 
     In an embodiment, the sensor assembly  283  may be disposed on the second sidewall  214  of the first housing  210 - 1 . The sensor assembly  283  may include the image sensor  281  and a sensor circuit board  282  to which the image sensor  281  is electrically connected. The image sensor  281  may be aligned with the sixth opening area  2143 , which is formed in the second sidewall  214  of the first housing  210 - 1 , such that light reflected or refracted by the second reflective member  291  is incident on the image sensor  281 . For example, the image sensor  281  may be disposed to face one surface of the second reflective member  291  through the sixth opening area  2143 . The image sensor  281  may be configured to receive light that passes through the lens and that is reflected by the second reflective member  291  and generate an electrical signal based on the received optical signal. The sensor circuit board  282  may be electrically connected with a connector  285 , and the connector  285  may be electrically connected to a printed circuit board (e.g., the printed circuit board  150  of  FIG. 3 ) of an electronic device (e.g., the electronic device  100  of  FIGS. 1 to 3 ). For example, the sensor circuit board  282  may be electrically connected with the connector  285  through a connecting member  284  (e.g., a flexible circuit board or a cable). 
     In an embodiment, the second reflective member  291  may change the travel path of external light passing through the lens. The second reflective member  291  may be located in the first optical axis direction d with respect to the lens assembly  220 . For example, the second reflective member  291  may direct, toward the image sensor  281 , external light passing through the lens and travelling in the first optical axis direction {circle around ( 1 )}, by reflecting or refracting the external light in a direction (e.g., the −y-axis direction) perpendicular to the first optical axis direction {circle around ( 1 )}. For example, the second reflective member  291  may include a mirror or prism that has an inclined surface. In another embodiment, the camera module  200  may not include the second reflective member  291 . When the second reflective member  291  is omitted as in the other embodiment, the position of the image sensor  281  may be changed to be aligned with the lens assembly  220  in the direction of the optical axis L. 
     In an embodiment, the flexible circuit board  292  may surround some of the sidewalls  213 ,  214 ,  215 , and  216  of the first housing  210 - 1 . The first coils  261 , the second coils  271 , and the third coil  273  may be disposed on the flexible circuit board  292 . For example, the flexible circuit board  292  may surround the first sidewall  213 , the second sidewall  214 , and the third sidewall  215  of the first housing  210 - 1  such that the first coils  261  and the second coils  271  are located in the first sidewall  213  (e.g., the first opening area  2131  and the second opening area  2132 ) and the second sidewall  214  (e.g., the third opening area  2141  and the fourth opening area  2142 ) and the third coil  273  is located in the third sidewall  215  (e.g., the fifth opening area  2151 ). In an embodiment, the flexible circuit board  292  may be electrically connected with the printed circuit board (e.g., the printed circuit board  150  of  FIG. 3 ) of the electronic device (e.g., the electronic device  100  of  FIGS. 1 to 3 ). The flexible circuit board  292  may include a flexible printed circuit board (FPCB) or a rigid-flexible printed circuit board (RFPCB). 
       FIG. 6A  is a view illustrating the stopper member  240  of the camera module  200  according to an embodiment.  FIG. 6B  is a view illustrating the stopper member  240  of the camera module  200  according to an embodiment. 
     Referring to  FIGS. 6A and 6B , the stopper member  240  of the camera module  200  according to an embodiment may include a base part  243  and stopper parts  244 ,  245 , and  249  coupled to the base part  243 . The stopper parts  244 ,  245 , and  249  may include the linear stopper  244 , the buffer stopper  245 , and the rotational stopper  249 . For example, a first stopper member (e.g., the first stopper member  241  of  FIG. 5 ) and second stopper members (e.g., the second stopper members  242  of  FIG. 5 ) may be formed in the same shape, and components of the first stopper member  241  and components of the second stopper members  242  may be the same as each other. 
     In an embodiment, the stopper parts  244 ,  245 , and  249  may be coupled to the base part  243 . The base part  243  may be a part coupled with the camera housing  210  such that the stopper member  240  is fixed to a camera housing (e.g., the camera housing  210  of  FIGS. 4 and 5 ). For example, the base part  243  may be fixedly coupled to a first housing (e.g., the first camera housing  210 - 1  of  FIGS. 4 and 5 ). In an embodiment, the base part  243  may have a predetermined rigidity to stably support the stopper parts  244 ,  245 , and  249  without a change in shape or position when an external force or impact is applied to the stopper parts  244 ,  245 , and  249 . The base part  243  may be formed of various materials having rigidity higher than or equal to a predetermined level. For example, the base part  243  may be formed of steel use stainless (SUS). However, without being limited thereto, the base part  243  may be formed of various materials. 
     In an embodiment, the base part  243  may be formed of a material having a higher rigidity than the stopper parts  244 ,  245 , and  249 . For example, the base part  243  may be formed of a hard material, and the stopper parts  244 ,  245 , and  249  may be formed of a soft material. In various embodiments, the stopper member  240  may be implemented such that the base part  243  and the stopper parts  244 ,  245 , and  249  are integrally formed with one another through an insert molding process. However, a manufacturing process for the stopper member  240  is not limited to the insert molding, and the stopper member  240  may be manufactured through various manufacturing processes. In another example, the stopper member  240  may be assembled as one component by manufacturing the base part  243  and the stopper parts  244 ,  245 , and  249  through separate processes and thereafter bonding the stopper parts  244 ,  245 , and  249  to the base part  243  or fitting the stopper parts  244 ,  245 , and  249  into the base part  243 . 
     In an embodiment, the base part  243  may include a first portion  243   a  extending in the direction of the optical axis L, a second portion  243   b  substantially vertically extending from one end of the first portion  243   a  that faces the long-side direction (e.g., the direction of the optical axis L), and third portions  243   c  substantially vertically extending from one end of the first portion  243   a  that faces the short-side direction. The rotational stopper  249  may be disposed on part of the first portion  243   a . The linear stopper  244  and the buffer stopper  245  may be disposed on part of the first portion  243   a  and part of the second portion  243   b.    
     In an embodiment, the linear stopper  244  may be disposed on a first surface  2433  of the second portion  243   b , and the buffer stopper  245  may be disposed on a second surface  2434  of the second portion  243   b . For example, the first surface  2433  of the second portion  243   b  may be defined as the surface facing toward the rotational stopper  249 , and the second surface  2434  of the second portion  243   b  may be defined as the surface facing away from the first surface  2433  of the second portion  243   b . For example, the first surface  2433  of the second portion  243   b  may be construed as the surface facing toward an opposite end of the first portion  243   a  in the long-side direction. In various embodiments, the linear stopper  244  and the buffer stopper  245  may be integrally formed through an insert molding process and may be formed to pass through at least parts of the second portion  243   b . However, a manufacturing method for the linear stopper  244  and the buffer stoppers  245  is not limited to the described contents. In another example, the linear stopper  244  and the buffer stopper  245  may be manufactured as separate components and may be bonded to the first surface  2433  and the second surface  2434  of the second portion  243   b . In various embodiments, the linear stopper  244  and the buffer stopper  245  may contain an elastic material, a flexible material, or an injection material. For example, the linear stopper  244  and the buffer stopper  245  may be formed of various materials including rubber, urethane, Poron, and sponge. In various embodiments, the linear stopper  244  and the buffer stopper  245  may be formed of the same material, or may be formed of different materials. 
     In an embodiment, at least part of the linear stopper  244  may be formed to pass through part of the first portion  243   a . For example, the linear stopper  244  may extend from a partial area of a first surface  2431  of the first portion  243   a  through the first portion  243   a  toward a second surface  2432  of the first portion  243   a . For example, the linear stopper  244  may extend in substantially the same direction as the direction in which the second portion  243   b  extends from the first portion  243   a.    
     In an embodiment, the linear stopper  244  may be configured to be brought into contact with, or spaced apart from, the lens assembly  220  as the lens assembly (e.g., the lens assembly  220  of  FIG. 5 ) moves in the direction of the optical axis L. For example, the linear stopper  244  may provide a function of limiting a movement of the lens assembly  220 , by making contact with the lens assembly  220 . Furthermore, the linear stopper  244  may provide the function of a damper capable of absorbing or dissipating an impact when the lens assembly  220  makes contact with, or collides with, the linear stopper  244 . For example, to provide the function of the damper, the linear stopper  244  may be formed of an elastic material or a flexible material. 
     In an embodiment, the linear stopper  244  may have a recess  248  formed in at least part thereof. For example, the linear stopper  244  may be configured such that due to the recess  248 , one portion (e.g., a flexible portion  246 ) moves (or elastically deforms) in a direction toward or away from another portion (e.g., a fixed portion  247 ). In an embodiment, the linear stopper  244  may include the flexible portion  246  and the fixed portion  247  facing each other with the recess  248  therebetween. For example, the fixed portion  247  may be fixed to the first surface  2433  of the second portion  243   b , and the flexible portion  246  may extend from the fixed portion  247  and may be spaced apart from the fixed portion  247  by a predetermined gap. In various embodiments, the linear stopper  244  may be configured such that when an external force is applied to the flexible portion  246 , the flexible portion  246  deforms in the direction toward the fixed portion  247  and when the external force is removed, the flexible portion  246  deforms in the direction away from the fixed portion  247 . Accordingly, the linear stopper  244  may absorb and/or dissipate an impact through deformation or movement of the linear stopper  244  (e.g., the flexible portion  246 ) when an external force is applied to the linear stopper  244 . 
     In an embodiment, the rotational stopper  249  may be configured to prevent rotation of the lens assembly (e.g., the lens assembly  220  of  FIG. 5 ). The rotational stopper  249  may pass through the first surface  2431  of the first portion  243   a  and may extend toward the second surface  2432  of the first portion  243   a . When the lens assembly  220  rotates, the rotational stopper  249  may limit the rotation of the lens assembly  220  by making contact with part of the lens assembly  220 . Furthermore, the rotational stopper  249  may be formed of an elastic material (or a flexible material) to prevent damage when the lens assembly  220  makes contact with the rotational stopper  249 . In various embodiments, the rotational stopper  249  may be formed of substantially the same material as the linear stopper  244  or the buffer stopper  245 . 
     Hereinafter, an operation of limiting a movement range of the lens assembly  220  in the direction of the optical axis L by the stopper member  240 , an operation of preventing rotation of the lens assembly  220 , and an operation of absorbing and/or alleviating an impact (or noise) caused by a movement of the lens assembly  220  will be described with reference to  FIGS. 7 and 8 . 
       FIG. 7  is a view illustrating operations of the lens assembly  220  and the stopper members  241  and  242  of the camera module  200  according to an embodiment.  FIG. 8  is a view illustrating operations of the lens assembly  220  and the stopper members  241  and  242  of the camera module  200  according to an embodiment. 
       FIG. 7  is a perspective view of the camera module  200  according to an embodiment. For example,  FIG. 7  may be a view in which a second housing (e.g., the second housing  210 - 2  of  FIGS. 4 and 5 ) and the sensor assembly  283  of the camera module  200  are omitted.  FIG. 8  is a plan view of the camera module  200  according to an embodiment. For example,  FIG. 8  may be a view of the camera module  200  illustrated in  FIG. 7  as viewed in the −z-axis direction. 
     Referring to  FIGS. 7 and 8 , the camera module  200  according to an embodiment may include the first housing  210 - 1 , the lens assembly  220 , the reflective member assembly  230 , the stopper members  241  and  242 , the sensor assembly  283 , the second reflective member  291 , and the flexible circuit board  292 . Some of the components of the camera module  200  illustrated in  FIGS. 7 and 8  are identical or similar to the components of the camera module  200  described above with reference to  FIGS. 4 to 6B , and therefore repetitive descriptions will hereinafter be omitted. 
     In an embodiment, the first housing  210 - 1  may accommodate the reflective member assembly  230 , the lens assembly  220 , and the second reflective member  291  inside. According to the embodiment illustrated in  FIGS. 7 and 8 , the reflective member assembly  230 , the lens assembly  220 , and the second reflective member  291  may be sequentially disposed in the first housing  210 - 1  in the first optical axis direction {circle around ( 1 )}. For example, the reflective member assembly  230  may be located in the second optical axis direction {circle around ( 2 )} with respect to the lens assembly  220 , and the second reflective member  291  may be located in the first optical axis direction d with respect to the lens assembly  220 . 
     In an embodiment, the stopper members  241  and  242  may be coupled to at least some of the sidewalls  213 ,  214 ,  215 , and  216  of the first housing  210 - 1 . The stopper members  241  and  242  may be coupled to the sidewalls (the first sidewall  213  and the second sidewall  214 ) parallel to the optical axis L among the sidewalls  213 ,  214 ,  215 , and  216  of the first housing  210 - 1 . For example, the stopper members  241  and  242  may be coupled to the first sidewall  213  and the second sidewall  214  of the first housing  210 - 1 . 
     In an embodiment, the lens assembly  220  may be configured to move in the direction of the optical axis L. For example, the lens assembly  220  may linearly move in the first optical axis direction d or the second optical axis direction {circle around ( 2 )}. As the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )}, the distance between the lens assembly  220  and the second reflective member  291  in the direction of the optical axis L may decrease. As the lens assembly  220  moves in the second optical axis direction {circle around ( 2 )}, the distance between the lens assembly  220  and the reflective member assembly  230  in the direction of the optical axis L may decrease. 
     In an embodiment, the lens assembly  220  may include the lens carrier  222 , the lens unit  221 , at least part of which is accommodated in the lens carrier  222 , and a fixing member  223  coupled to an end portion of the lens carrier  222  that faces the first optical axis direction {circle around ( 1 )}. The lens unit  221  and the fixing member  223  may move in the direction of the optical axis L together with the lens carrier  222 . In an embodiment, the fixing member  223  may include a coupling portion  224  coupled to the lens carrier  222  and an extending portion  225  extending from the coupling portion  224 . For example, the extending portion  225  may extend toward the fourth sidewall  216  of the first housing  210 - 1  from an edge area of the coupling portion  224  that is adjacent to the first sidewall  213  of the first housing  210 - 1 . The extending portion  225  may extend from the coupling portion  224  toward the first stopper member  241 . For example, the extending portion  225  may extend in the first optical axis direction d by a specified length. For example, the fixing member  223  may be a component to which a baffle (not illustrated) is coupled. In various embodiments, the lens assembly  220  may not include the fixing member  223 . Furthermore, in various embodiments, the fixing member  223  may not include the extending portion  225 . 
     In an embodiment, the lens assembly  220  may be configured to be brought into contact with, or spaced apart from, at least a part (e.g., the linear stopper  244 ) of the stopper members  241  and  242  as the lens assembly  220  moves in the direction of the optical axis L. For example, the lens assembly  220  may be configured such that the extending portion  225  of the fixing member  223  makes contact with the first stopper member  241  when the lens assembly  220  moves in the first optical axis direction d and an end portion of the lens carrier  222  in the second optical axis direction  2  makes contact with the second stopper members  242  when the lens assembly  220  moves in the second optical axis direction  2 . 
     According to the illustrated embodiment, as the extending portion  225  of the fixing member  223  is configured to make contact with the first stopper member  241 , the lens assembly  220  may prevent contact and/or collision with the second reflective member  291  when the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )}. For example, the extending portion  225  of the fixing member  223  may be brought into contact with, or spaced apart from, the first stopper member  241  while moving in the direction of the optical axis L between one surface of the second reflective member  291  and the first sidewall  213  of the first housing  210 - 1 . However, the illustrated embodiment is illustrative, and in another embodiment, the camera module  200  may not include the second reflective member  291 . In the other embodiment, the fixing member  223  or the extending portion  225  of the fixing member  223  may be omitted. For example, when the camera module  200  does not include the second reflective member  291 , the lens assembly  220  may be configured such that the lens carrier  222  makes direct contact with the first stopper member  241  or the coupling portion  224  of the fixing member  223  makes contact with the first stopper member  241 . For example, when the fixing member  223  or the extending portion  225  of the fixing member  223  is omitted, the first stopper member  241  may be coupled to the first sidewall  213  so as to be located adjacent to the lens carrier  222  or the coupling portion  224  of the fixing member  223 . 
     In an embodiment, the stopper members  241  and  242  may be coupled to sidewalls (e.g., the first sidewall  213  and the second sidewall  214 ) of the first housing  210 - 1 . For example, the stopper members  241  and  242  may include the first stopper member  241 , at least part of which is located between the fourth sidewall  216  of the first housing  210 - 1  and the lens assembly  220 , and the second stopper members  242 , at least parts of which are located between the reflective member assembly  230  and the lens assembly  220 . In an embodiment, the first stopper member  241  may be coupled to the first sidewall  213  of the first housing  210 - 1 . The second stopper members  242  may be coupled to the first sidewall  213  and the second sidewall  214  of the first housing  210 - 1 . For example, a pair of second stopper members  242  may be provided to be symmetric to each other with respect to the optical axis. However, the number of second stopper members  242  is not limited to the illustrated embodiment. In another example, one second stopper member  242  may be provided and may be disposed on only one of the first sidewall  213  and the second sidewall  214 . 
     In an embodiment, the first stopper member  241  and the second stopper members  242  may be formed in substantially the same shape. For example, each of the first stopper member  241  and the second stopper members  242  may include the base part  243 , the linear stopper  244 , the buffer stopper  245 , and the rotational stopper  249 . 
     Hereinafter, the base part  243 , the linear stopper  244 , the buffer stopper  245 , and the rotational stopper  249  of the first stopper member  241  are referred to as the first base part, stopper  1 - 1 , stopper  2 - 1 , and stopper  3 - 1 , respectively, and the base part  243 , the linear stopper  244 , the buffer stopper  245 , and the rotational stopper  249  of each of the second stopper members  242  are referred to as the second base part, stopper  1 - 2 , stopper  2 - 2 , and stopper  3 - 2 , respectively. This is to distinguish between the components of the first stopper member  241  and the second stopper member  242  and does not mean that the shapes or functions thereof differ from each other. 
     In an embodiment, the first stopper member  241  may include the first base part  243  fixedly coupled to the first housing  210 - 1 , and stopper  1 - 1   244 , stopper  2 - 1   245 , and stopper  3 - 1   249  that are coupled to the first base part  243 . For example, the first base part  243  may be fit into the first sidewall  213  of the first housing  210 - 1 . The first base part  243  may include the first portion  243   a  and the second portion  243   b  extending substantially perpendicular from the first portion  243   a  toward the bottom surface  212  of the first housing  210 - 1 . 
     In an embodiment, the first stopper member  241  may be coupled to the first sidewall  213  of the first housing  210 - 1  such that stopper  1 - 1   244  faces the lens assembly  220 . For example, the first stopper member  241  may be coupled to the first sidewall  213  such that stopper  1 - 1   244  faces the second optical axis direction  2  and stopper  2 - 1   245  faces the first optical axis direction {circle around ( 1 )}. For example, stopper  1 - 1   244  may face the lens assembly  220  in the direction of the optical axis L, and stopper  2 - 1   245  may face the fourth sidewall  216  of the first housing  210 - 1  in the direction of the optical axis L. 
     In an embodiment, stopper  1 - 1   244  may be located in the first optical axis direction with respect to the lens assembly  220 . For example, stopper  1 - 1   244  may be located in the first optical axis direction d from the lens assembly  220  (or the extending portion  225  of the fixing member  223 ). Accordingly, stopper  1 - 1   244  may limit a movement range of the lens assembly  220  in the first optical axis direction {circle around ( 1 )}. Stopper  1 - 1   244  may be brought into contact with the lens assembly  220  when the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )} and may be spaced apart from the lens assembly  220  when the lens assembly  220  moves in the second optical axis direction {circle around ( 2 )}. 
     In an embodiment, stopper  1 - 1   244  may include the fixed portion  247  fixed to the second portion  243   b  of the first base part  243  and the flexible portion  246  extending from the fixed portion  247 . The recess  248  (or the elastic recess) may be formed between the fixed portion  247  and the flexible portion  246 . The flexible portion  246  may move or elastically deform toward the fixed portion  247  as the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )}. For example, the recess  248  may be narrowed as the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )}. 
     According to the embodiment illustrated in  FIG. 7 , when the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )}, the extending portion  225  of the fixing member  223  may make contact with the flexible portion  246  and may push the flexible portion  246  in the first optical axis direction {circle around ( 1 )}. At least part (e.g., the portion illustrated by the dotted line) of the flexible portion  246  may elastically deform while moving a specified distance in the first optical axis direction {circle around ( 1 )}. Accordingly, stopper  1 - 1   244  may serve as a stopper that restricts the extending portion  225  of the fixing member  223  from further moving in the first optical axis direction d and at the same time, may absorb or dissipate (e.g., damper) an impact caused by contact (collision) of the extending portion  225  of the fixing member  223  or may reduce noise. 
     In an embodiment, stopper  2 - 1   245  may prevent damage caused by collision with the fourth sidewall  216  of the first housing  210 - 1  when an excessive impact is applied to stopper  1 - 1   244 . 
     In an embodiment, the second stopper members  242  may include the second base parts  243  fixedly coupled to the first housing  210 - 1 , and stoppers  1 - 2   244 , stoppers  2 - 2   245 , and stoppers  3 - 2   249  that are coupled to the second base parts  243 . For example, the second base parts  243  may be fit into the first sidewall  213  and the second sidewall  214  of the first housing  210 - 1 . The second base parts  243  may include the first portions  243   a  and the second portions  243   b  substantially perpendicularly extending from the first portions  243   a  toward the bottom surface  212  of the first housing  210 - 1 . 
     In an embodiment, the second stopper members  242  may be coupled to the first sidewall  213  and the second sidewall  214  of the first housing  210 - 1  such that stoppers  1 - 2   244  face the lens assembly  220 . For example, the second stopper members  242  may be coupled to the first sidewall  213  and the second sidewall  214  such that stoppers  1 - 2   244  face the first optical axis direction and stoppers  2 - 2   245  face the second optical axis direction  2 . For example, stoppers  1 - 2   244  may face the lens assembly  220  in the direction of the optical axis L, and stoppers  2 - 2   245  may face the reflective member assembly  230  in the direction of the optical axis L. 
     In an embodiment, stoppers  1 - 2   244  may be located in the second optical axis direction  2  with respect to the lens assembly  220 . For example, stoppers  1 - 2   244  may be located in the second optical axis direction  2  from the lens assembly  220  (or the lens carrier  222 ). Accordingly, stoppers  1 - 2   244  may limit a movement range of the lens assembly  220  in the second optical axis direction  2 . Stoppers  1 - 2   244  may be brought into contact with the lens assembly  220  when the lens assembly  220  moves in the second optical axis direction  2  and may be spaced apart from the lens assembly  220  when the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )}. 
     In an embodiment, stoppers  1 - 2   244  may include the fixed portions  247  fixed to the second portions  243   b  of the second base parts  243  and the flexible portions  246  extending from the fixed portions  247 . The recesses  248  (or the elastic recesses) may be formed between the fixed portions  247  and the flexible portions  246 . The flexible portions  246  may move or elastically deform toward the fixed portions  247  as the lens assembly  220  moves in the second optical axis direction  2 . For example, the recesses  248  may be narrowed as the lens assembly  220  moves in the second optical axis direction  2 . 
     According to the embodiment illustrated in  FIG. 7 , when the lens assembly  220  moves in the second optical axis direction  2 , the lens carrier  222  may make contact with the flexible portions  246  and may push the flexible portions  246  in the second optical axis direction  2 . At least parts (e.g., the portions illustrated by the dotted lines) of the flexible portions  246  may elastically deform while moving a specified distance in the second optical axis direction {circle around ( 2 )}. Accordingly, stoppers  1 - 2   244  may serve as stoppers that restrict the lens carrier  222  from further moving in the second optical axis direction {circle around ( 2 )} and at the same time, may absorb or dissipate (e.g., damper) an impact caused by contact (collision) of the lens carrier  222  or may reduce noise. 
     In an embodiment, stoppers  2 - 2   245  may be configured such that at least parts thereof make contact with the reflective member assembly  230  when the reflective member assembly  230  performs a rotary motion for an optical image stabilizer (OIS) function. Accordingly, stoppers  2 - 2   245  may limit a rotational range of the reflective member assembly  230 , or may prevent damage to the reflective member assembly  230 . The relationship between stoppers  2 - 2   245  of the second stopper members  242  and the reflective member assembly  230  will be described below with reference to  FIGS. 11A and 11B . 
     In an embodiment, the rotational stopper  249  (hereinafter, stopper  3 - 1 ) of the first stopper member  241  and the rotational stoppers  249  (hereinafter, stoppers  3 - 2 ) of the second stopper members  242  may limit and/or prevent rotation of the lens assembly  220 . For example, stopper  3 - 1   249  and stoppers  3 - 2   249  may make contact with the lens carrier  222  to prevent rotation of the lens assembly  220  about the optical axis L inside the first housing  210 - 1 . 
     In an embodiment, stopper  3 - 1   249  and stoppers  3 - 2   249  may be spaced apart from the lens assembly  220  by a predetermined gap, and when the lens assembly  220  rotates about the optical axis L by an external impact or shake, at least parts of stopper  3 - 1   249  and stoppers  3 - 2   249  may make contact with the lens assembly  220  to prevent excessive rotation of the lens assembly  220 . For example, stopper  3 - 1   249  and stoppers  3 - 2   249  may be spaced apart from the lens assembly  220  by a minute gap to substantially limit rotation of the lens assembly  220 . When the lens assembly  220  rotates about the optical axis L in the clockwise direction with respect to the drawings, the lens assembly  220  may make contact with stopper  3 - 2   249  of the second stopper member  242  disposed on the second sidewall  214 . Furthermore, when the lens assembly  220  rotates about the optical axis L in the counterclockwise direction, the lens assembly  220  may make contact with stopper  3 - 1   249  of the first stopper member  241  and stopper  3 - 2   249  of the second stopper member  242  disposed on the first sidewall  213 . 
     As illustrated in  FIG. 8 , stopper  3 - 1   249  and stoppers  3 - 2   249  may be disposed to overlap the lens assembly  220  when the camera module  220  is viewed from above (e.g., in the −z-axis direction). For example, stopper  3 - 1   249  may overlap the extending portion  225  of the fixing member  223 , and stoppers  3 - 2   249  may overlap the lens carrier  222 . In various embodiments, stopper  3 - 1   249  and stoppers  3 - 2   249  may be configured to overlap the lens assembly  220  in the state in which the lens assembly  220  moves in the first optical axis direction d to the maximum or in the state in which the lens assembly  220  moves in the second optical axis direction  2  to the maximum. Accordingly, rotation of the lens assembly  220  may be prevented even in the state in which the lens assembly  220  moves in the first optical axis direction d or the second optical axis direction  3 . 
     Referring to  FIG. 8 , the camera module  200  according to an embodiment may include the first reflective member  231  and the second reflective member  291  and may be configured such that the travel path of external light is changed at least once. For example, external light may be incident on the first reflective member  231  in a first direction (e.g., the z-axis direction) perpendicular to the direction of the optical axis L (e.g., the x-axis direction), may be reflected or refracted by the first reflective member  231 , and may be incident on the lens unit  221  in the direction of the optical axis L. The light passing through the lens unit  221  may be reflected or refracted by the second reflective member  291  and may be incident on the image sensor  281  in a second direction (e.g., the y-axis direction) perpendicular to the direction of the optical axis L and the first direction. However, the structure and configuration of the camera module  200  is not limited to the illustrated embodiment, and the camera module  200  may not include the second reflective member  291 . When the second reflective member  291  is not included, the image sensor  281  may be partially aligned with the lens unit  221  in the direction of the optical axis L. 
     Referring to  FIGS. 7 and 8 , the camera module  200  according to an embodiment may limit a movement range of the lens assembly  220  in the direction of the optical axis L through the first stopper member  241  and the second stopper members  242  and may alleviate an impact and noise caused by a movement of the lens assembly  220 . For example, the linear stoppers  244  of the first stopper member  241  and the second stopper members  242  may be configured to simultaneously perform functions of a damper and a stopper. According to an embodiment, when the lens assembly  220  moves in the direction of the optical axis L by a shake of the camera module  200  in the state in which power is not supplied to the camera module  200 , an excessive movement of the lens assembly  220  may be limited, and noise and vibration caused by collision with other component(s) may be improved. 
       FIG. 9  is a view illustrating a rotary motion of the reflective member assembly  230  of the camera module  200  according to an embodiment.  FIG. 10  is a view illustrating the reflective member assembly  230 , the guide structure  250 , and the second drive member  270  of the camera module  200  according to an embodiment. 
     Referring to  FIGS. 9 and 10 , the camera module  200  according to an embodiment may be configured to provide an optical image stabilizer (OIS) function by rotating the reflective member assembly  230  about the first axis of rotation R 1  or the second axis of rotation R 2  in a predetermined range. 
     The camera module  200  according to an embodiment may include the reflective member assembly  230 , the guide structure  250 , and the second drive member  270 . The guide structure  250  may form the axes of rotation R 1  and R 2  for rotation of the reflective member assembly  230 . The second drive member  270  may provide a driving force (e.g., an electro-magnetic force) for rotation of the reflective member assembly  230 . 
     In an embodiment, the reflective member assembly  230  may be configured to rotate about the first axis of rotation R 1  perpendicular to the optical axis L (e.g., the x-axis) in a specified range. For example, the first axis of rotation R 1  may be parallel to the z-axis. In an embodiment, the reflective member assembly  230  may be configured to rotate about the second axis of rotation R 2  perpendicular to the optical axis L and the first axis of rotation R 1  in a specified range. For example, the second axis of rotation R 2  may be parallel to the y-axis. For example, a rotary motion of the reflective member assembly  230  about the first axis of rotation R 1  may be understood as a yaw tilt motion or a yawing motion. For example, a rotary motion of the reflective member assembly  230  about the second axis of rotation R 2  may be understood as a pitch tilt motion or a pitching motion. 
     In an embodiment, the reflective member assembly  230  may include the first reflective member  231  and the holder  232  in which at least part of the first reflective member  231  is accommodated. For example, the first reflective member  231  may be coupled to the holder  232  so as to rotate and/or move together with the holder  232 . In an embodiment, at least a part (e.g., the second magnets  272 ) of the second drive member  270  may be disposed on the holder  232 . The first guide member  251  may be coupled to the holder  232  so as to be rotatable about the first axis of rotation R 1 . 
     In an embodiment, the holder  232  may include border parts  233 ,  234 , and  235  surrounding at least part of the first reflective member  231 . For example, the border parts of the holder  232  may include the first border part  233  and the second border part  234  that extend parallel to the direction of the optical axis L and face each other, and the third border part  235  that connects the first border part  233  and the second border part  234  and that is perpendicular to the direction of the optical axis L. For example, the first border part  233  and the second border part  234  may refer to the sidewalls facing the direction (e.g., the y-axis direction) perpendicular to the optical axis L, and the third border part  235  may refer to the sidewall facing the second optical axis direction (e.g., the x-axis direction). Referring to  FIG. 5  together, the first border part  233  of the holder  232  may face the +y-axis direction to face the first sidewall  213  (e.g., the second opening area  2132 ) of the first housing (e.g., the first housing  210 - 1  of  FIG. 5 ), the second border part  234  may face the −y-axis direction to face the second sidewall  214  (e.g., the fourth opening area  2142 ) of the first housing  210 - 1 , and the third border part  235  may face the +x-axis direction to face the third sidewall  215  (e.g., the fifth opening area  2151 ). 
     In an embodiment, the second magnets  272  may be disposed on the first border part  233  and the second border part  234  of the holder  232 . The first guide member  251  may be coupled to the third border part  235  of the holder  232  so as to be rotatable. In an embodiment, the holder  232  may be configured to rotate about the first axis of rotation R 1  relative to the first guide member  251 . The holder  232  may be configured to rotate about the second axis of rotation R 2  relative to the second guide member  252  together with the first guide member  251 . 
     In an embodiment, the guide structure  250  may include the first guide member  251  coupled to the holder  232  so as to be rotatable about the first axis of rotation R 1  and the second guide member  252  coupled to the first guide member  251  so as to be rotatable about the second axis of rotation R 2 . 
     In an embodiment, the first guide member  251  may be located between the holder  232  and the second guide member  252 . The first guide member  251  may include a first surface  253  facing the holder  232  and a second surface  254  facing the second guide member  252 . For example, the first surface  253  may refer to the surface facing the first optical axis direction  1 , and the second surface  254  may refer to the surface facing the second optical axis direction  2 . In an embodiment, the third magnet  274  may be disposed on the second surface  254  of the first guide member  251 . 
     In an embodiment, the first guide member  251  may be coupled to the third border part  235  of the holder  232 . The first guide member  251  may be configured to rotate about the first axis of rotation R 1  relative to the holder  232  in a predetermined range. 
     In an embodiment, the first axis of rotation R 1  may be formed by the first surface  253  of the first guide member  251  and the third border part  235  of the holder  232 . For example, the first surface  253  of the first guide member  251  may be formed to be a curved surface having a substantially arc shape, and a curved area  236  corresponding to the shape of the first surface  253  may be formed on the third border part  235  facing the first guide member  251 . In an embodiment, the center of the arc of the first surface  253  may be defined as the first axis of rotation R 1 . For example, the first surface  253  may be formed to be a curved surface having a predetermined curvature, and the first axis of rotation R 1  may be understood as a virtual axis passing through the center of curvature of the curved surface in the z-axis direction. 
     In an embodiment, a plurality of second balls  257  for guiding rotation of the holder  232  may be disposed between the first surface  253  of the first guide member  251  and the third border part  235 . For example, the first guide member  251  may have, on the first surface  253  thereof, second recesses  2531  in which at least parts of the plurality of second balls  257  are accommodated so as to be rotatable. The third border part  235  may have, on the curved area  236  thereof, third recesses  2361  overlapping the second recesses  2531  in the direction of the optical axis L (e.g., the x-axis direction). For example, as many second recesses  2531  and third recesses  2361  as the plurality of second balls  257  may be formed. In an embodiment, the plurality of second balls  257  may be configured to roll in the spaces between the second recesses  2531  and the third recesses  2361 . The plurality of second balls  257  may rotate at specified positions in the spaces, or may rotate while linearly moving. 
     In an embodiment, the first guide member  251  may be coupled with the second guide member  252 . The first guide member  251  may be configured to rotate about the second axis of rotation R 2  relative to the second guide member  252 . For example, the first guide member  251 , when rotating about the second axis of rotation R 2 , may rotate together with the holder  232 . 
     In an embodiment, the second guide member  252  may be disposed to face the second surface  254  of the first guide member  251 . The second guide member  252  may be coupled to the first guide member  251  so as to be rotatable about the second axis of rotation R 2  in a predetermined range.  FIG. 9  is a view in which the first housing (e.g., the first housing  210 - 1  of  FIG. 5 ) is omitted. However, the second guide member  252  may be coupled to the third sidewall (e.g., the third sidewall  215  of  FIG. 5 ) of the first housing  210 - 1 . For example, the second guide member  252  may be fixedly disposed on the third sidewall  215  of the first housing  210 - 1 , and the first guide member  251  and the reflective member assembly  230  may rotate together relative to the second guide member  252 . 
     In an embodiment, the second axis of rotation R 2  may be formed by the second surface  254  of the first guide member  251  and the second guide member  252 . For example, the second guide member  252  may include protruding portions  256  protruding toward the second surface  254  of the first guide member  251 , and fourth recesses  2561  having an arc shape may be formed on the protruding portions  256 . Fifth recesses  2551  having an arc shape corresponding to the fourth recesses  2561  may be formed on edge portions  255  of the first guide member  251  facing the second guide member  252 . In an embodiment, the center of the arcs of the fourth recesses  2561  or the fifth recesses  2551  may be defined as the second axis of rotation R 2 . For example, the fourth recesses  2561  or the fifth recesses  2551  may be formed of curves having a predetermined curvature, and the second axis of rotation R 2  may be understood as a virtual axis passing through the center of curvature of the curves in the y-axis direction. 
     In an embodiment, a plurality of third balls  258  for guiding rotation of the first guide member  251  may be disposed between the protruding portions  256  of the second guide member  252  and the edge portions  255  of the first guide member  251 . For example, the plurality of third balls  258  may be accommodated in the fourth recesses  2561  and the fifth recesses  2551  so as to be rotatable. For example, the fourth recesses  2561  of the second guide member  252  and the fifth recesses  2551  of the first guide member  251  may be formed to overlap each other in the direction of the optical axis L (e.g., the x-axis direction). For example, as many second recesses  2531  and third recesses  2361  as the plurality of third balls  258  may be formed. In an embodiment, the plurality of third balls  258  may be configured to roll in the spaces between the fourth recesses  2561  and the fifth recesses  2551 . The plurality of third balls  258  may rotate at specified positions in the spaces, or may rotate while linearly moving. 
     In an embodiment, an opening portion  2521  may be formed in the central area of the second guide member  252 . For example, the opening portion  2521 , when viewed in the direction of the optical axis L, may overlap part of the second surface  254  of the first guide member  251 . The third coil  273  may face the third magnet  274 , which is disposed on the second surface  254  of the first guide member  251 , through the opening portion  2521 . For example, the opening portion  2521 , when viewed in the direction of the optical axis L, may overlap the fifth opening area (e.g., the fifth opening area  2151  of  FIG. 5 ) of the first housing (e.g., the first housing  210 - 1  of  FIG. 5 ) such that the third coil  273  interacts with the third magnet  274 . 
     In an embodiment, the second drive member  270  may include the second coils  271  and the second magnets  272  configured to rotate the reflective member assembly  230  about the first axis of rotation R 1 , and the third coil  273  and the third magnet  274  configured to rotate the reflective member assembly  230  about the second axis of rotation R 2 . For example, the second coils  271  and the second magnets  272  may electro-magnetically interact with each other. For example, the third coil  273  and the third magnet  274  may electro-magnetically interact with each other. 
     In an embodiment, the second magnets  272  may be disposed on the first border part  233  and the second border part  234  of the holder  232 . The second coils  271  may be disposed on the first sidewall  213  and the second sidewall  214  of the first housing (e.g., the first housing  210 - 1  of  FIG. 5 ) to face the second magnets  272 . Although the first housing  210 - 1  is not illustrated in  FIG. 9 , the second coils  271  may be located in the second opening area  2132  of the first sidewall  213  and the fourth opening area  2142  of the second sidewall  214 . In an embodiment, the camera module  200  may rotate the reflective member assembly  230  about the first axis of rotation R 1  by controlling an electric current flowing through the second coils  271 . For example, the second coils  271  may be located in a magnetic field formed by the second magnets  272 . In an embodiment, the processor (e.g., the processor  520  of  FIG. 19  and/or an image signal processor  660  of  FIG. 20 ) may control the direction and/or strength of the electric current passing through the second coils  271 . An electro-magnetic force (e.g., Lorentz force) may be applied to the second magnets  272  to correspond to the direction of the electric current passing through the second coils  271 . The reflective member assembly  230  may rotate about the first axis of rotation R 1  by the electro-magnetic force. 
     In an embodiment, the third magnet  274  may be disposed on the second surface  254  of the first guide member  251 . The third coil  273  may be disposed on the third sidewall  215  of the first housing (e.g., the first housing  210 - 1  of  FIG. 5 ) to face the third magnet  274 . Although the first housing  210 - 1  is not illustrated in  FIG. 9 , the third coil  273  may be located in the fifth opening area  2151  of the third sidewall  215 . In an embodiment, the camera module  200  may rotate the first guide member  251  and the reflective member assembly  230  about the second axis of rotation R 2  by controlling an electric current flowing through the third coil  273 . For example, the third coil  273  may be located in a magnetic field formed by the third magnet  274 . In an embodiment, the processor (e.g., the processor  520  of  FIG. 19  and/or an image signal processor  660  of  FIG. 20 ) may control the direction and/or strength of the electric current passing through the third coil  273 . An electro-magnetic force (e.g., Lorentz force) may be applied to the third magnet  274  to correspond to the direction of the electric current passing through the third coil  273 . The first guide member  251  and the reflective member assembly  230  may rotate about the second axis of rotation R 2  by the electro-magnetic force. 
       FIG. 11A  is a view illustrating the reflective member assembly  230 , the guide structure  250 , and the second stopper members  242  of the camera module  200  according to an embodiment.  FIG. 11B  is a view illustrating the reflective member assembly  230  and the second stopper members  242  of the camera module  200  according to an embodiment. 
     Referring to  FIGS. 11A and 11B , the camera module  200  according to an embodiment may include a stopper structure that limits a rotational range of the reflective member assembly  230 . For example, the stopper structure may guide a rotary motion of the reflective member assembly  230  within a specified angle range, and when the reflective member assembly  230  rotates through more than the specified angle, the rotation of the reflective member assembly  230  may be limited by contact of the stopper structure. 
     The camera module  200  according to an embodiment may include the reflective member assembly  230 , the first guide member  251 , the second guide member  252 , and the second stopper members  242 . The stopper structure may include a structure formed on the reflective member assembly  230  and the first guide member  251  and a structure formed on the second guide member  252 . 
     In an embodiment, protrusions  237  and  238  protruding toward the first guide member  251  may be formed on the third border part  235  of the holder  232 . For example, the protrusions  237  and  238  may include the first protrusion  237  and the second protrusion  238  spaced apart from the first protrusion  237 . The first protrusion  237  and the second protrusion  238  may limit a rotational range of the reflective member assembly  230  by making contact with extensions  259   a  and  259   b  of the first guide member  251  when the reflective member assembly  230  (or the holder  232 ) rotates about a first axis of rotation (e.g., the first axis of rotation R 1  of  FIG. 9 ) relative to the first guide member  251 . According to various embodiments, the first protrusion  237  and the second protrusion  238  may be formed to be one portion without being distinguished from each other. 
     In an embodiment, the first guide member  251  may have, at an upper edge (e.g., the edge facing the +z-axis direction), the extensions  259   a  and  259   b  extending to surround at least parts of the protrusions  237  and  238 . For example, the extensions  259   a  and  259   b  may include the first extension  259   a  located adjacent to the first protrusion  237  and the second extension  259   b  located adjacent to the second protrusion  238 . For example, the first protrusion  237  and the second protrusion  238  may be located inward of the extensions  259   a  and  259   b . For example, when the reflective member assembly  230  and the first guide member  251  are viewed from above (in the −z-axis direction), the first protrusion  237  and the second protrusion  238  may be disposed to be accommodated in the space formed by the extensions  259   a  and  259   b . When the reflective member assembly  230  (or the holder  232 ) rotates about the first axis of rotation (e.g., the first axis of rotation R 1  of  FIG. 9 ) relative to the first guide member  251 , inner sidewalls of the extensions  259   a  and  259   b  may make contact with the protrusions  237  and  238  and may limit a rotational range of the reflective member assembly  230 . For example, when the reflective member assembly  230  rotates about the first axis of rotation R 1  in the clockwise direction by a predetermined angle with respect to  FIGS. 11A and 11B , the second protrusion  238  may make contact with the second extension  259   b , and when the reflective member assembly  230  rotates about the first axis of rotation R 1  in the counterclockwise direction by a predetermined angle, the first protrusion  237  may make contact with the first extension  259   a.    
     In an embodiment, bumpers  259   c  and  259   d  may be formed at upper and lower edges of the second guide member  252 . For example, the bumpers  259   c  and  259   d  may include the first bumper  259   c  located over the opening  2521  of the second guide member  252  (e.g., in the +z-axis direction) and the second bumper  259   d  located under the opening  2521  (e.g., in the −z-axis direction). The bumpers  259   c  and  259   d  may limit a rotational range of the first guide member  251  by making contact with part of the first guide member  251  when the first guide member  251  rotates about a second axis of rotation (e.g., the second axis of rotation R 2  of  FIG. 9 ). In various embodiments, the bumpers  259   c  and  259   d  may be formed of an elastic material or a flexible material to absorb an impact caused by contact of the first guide member  251 . 
     In an embodiment, the second stopper members  242  may be configured to limit a rotational range of the reflective member assembly  230  together with the stopper (e.g., a primary stopper). For example, at least parts of the second stopper members  242  may perform a function of a secondary stopper against a rotary motion of the reflective member assembly  230 . 
     In an embodiment, the second stopper members  242  may be configured such that the buffer stoppers  245  are located adjacent to border parts (e.g., the first border part  233  and the second border part  234 ) of the holder  232 . For example, the holder  232  may have, on the border parts  233  and  234  thereof, step portions  239   a  and  239   b  on which at least parts of the buffer stoppers  245  are disposed. For example, the step portions  239   a  and  239   b  may include the first step portion  239   b  formed on the first border part  233  and the second step portion  239   a  formed on the second border part  234 . For example, at least parts of the border parts  233  and  234  may be recessed to form the step portions  239   a  and  239   b , and the step portions  239   a  and  239   b  may extend in the z-axis direction. In an embodiment, at least parts of the buffer stoppers  245  of the second stopper members  242  may be disposed on the step portions  239   a  and  239   b . For example, as illustrated in  FIG. 11B , the buffer stoppers  245  may overlap the first step portion  239   b  and the second step portion  239   a  when the reflective member assembly  230  is viewed from above (e.g., in the −z-axis direction). 
     In an embodiment, when the reflective member assembly  230  rotates through more than a specified angle, the second stopper members  242  may make contact with the holder  232  and may limit the rotation of the reflective member assembly  230 . For example, the buffer stoppers  245  may be configured to make contact with the inside surface of the first step portion  239   b  or the second step portion  239   a  in response to rotation of the holder  232 . In an embodiment, when an excessive movement of the reflective member assembly  230  is caused by an external impact, the second stopper members  242  may make contact with the holder  232  and may absorb the impact and prevent damage. For example, the buffer stoppers  245  may be formed of an elastic material or a flexible material and thus may be configured to prevent damage when colliding with the holder  232 .

FIG. 14  is a view illustrating operations of the support member  340  and the damping member  350  of the camera module  300  according to an embodiment. 
     Referring to  FIGS. 12, 13A, and 13B , the camera module  300  according to an embodiment may include a camera housing  310  (e.g., the camera housing  210  of  FIGS. 4 and 5 ), a lens assembly  320  (e.g., the lens assembly  220  of  FIGS. 4 and 5 ), a reflective member assembly  330  (e.g., the reflective member assembly  230  of  FIGS. 4 and 5 ), stopper members  370  (e.g., the stopper member  240  of  FIGS. 4 and 5 ), the support member  340 , and the damping member  350 . 
       FIGS. 12, 13A, and 13B  illustrate the camera module  300  according to another embodiment that does not include the first stopper member (e.g., the first stopper member  241  of  FIGS. 7 and 8 ) in the camera module  200  illustrated in  FIGS. 4 to 8  and includes the support member  340  and the damping member  350 . 
     Some of the components of the camera module  300  illustrated in  FIGS. 12, 13A, and 13B  are identical or similar to the components of the camera module  200  illustrated in  FIGS. 4 to 8 , and therefore repetitive descriptions will hereinafter be omitted. The camera housing  310  illustrated in  FIG. 12  may be referred to as the first housing  310  (e.g., the first housing  210 - 1  of  FIGS. 4 and 5 ), and  FIG. 12  may be a view in which a second housing (e.g., the second housing  210 - 2  of  FIGS. 4 and 5 ) is omitted. The stopper members  370  illustrated in  FIG. 12  may be referred to as the second stopper members (e.g., the second stopper members  242  of  FIGS. 7 and 8 ). For example, the positions, shapes, and/or functions of the second stopper members  370  illustrated in  FIG. 12  may be identical to the contents described above with reference to  FIGS. 6A to 11B . 
     In an embodiment, the camera housing  310  includes a first sidewall  312 , a second sidewall  313  parallel to the first sidewall  312 , a third sidewall  314  connecting one end of the first sidewall  312  and the second sidewall  313 , and a fourth sidewall  315  connecting the other ends of the first sidewall  312  and the second sidewall  313  and parallel to the third sidewall  314 . In an embodiment, the lens assembly  320  may include a lens unit  321  and a lens carrier  322  on which the lens unit  321  is disposed. In an embodiment, the reflective member assembly  330  may include a first reflective member  331  and a holder  332  supporting the first reflective member  331 . 
     In an embodiment, the support member  340  may at least partially make contact with the damping member  350  and may limit a movement range of the lens assembly  320  in the direction of an optical axis L. The support member  340  may be configured to move together with the lens assembly  320  in the direction of the optical axis L. For example, the support member  340  may extend from part of a lens carrier  322  in a first optical axis direction {circle around ( 1 )}. In various embodiments, the support member  340  may be integrally formed with the lens carrier  322 , or may be configured to be coupled to the lens carrier  322 . 
     In an embodiment, the support member  340  may extend toward a second reflective member receiving section  316  where a second reflective member (e.g., the second reflective member  291  of  FIGS. 5, 7, and 8 ) is disposed in a receiving space of the first housing  310 . For example, the first housing  310  may include the second reflective member receiving section  316  formed between a fourth sidewall  315  and the lens assembly  320 , and the support member  340  and the damping member  350  may be located in the second reflective member receiving section  316 . The second reflective member receiving section  316  may face the space in which the reflective member assembly  330  is disposed, with the lens assembly  320  therebetween. Although the second housing (e.g., the second housing  210 - 2  of  FIGS. 4 and 5 ) is not illustrated in  FIG. 12 , the second reflective member receiving section  316  may be located to be spaced apart from a light receiving area (e.g., the light receiving area  211  of  FIGS. 4 and 5 ) in the second housing  210 - 2  in the first optical axis direction {circle around ( 1 )}. Accordingly, radiation of noise caused by contact of the support member  340  and the damping member  350  to the outside of the camera housing  310  through the light receiving area  211  may be reduced. 
     In an embodiment, the support member  340  may include a first portion  341  extending parallel to the optical axis L, a second portion  342  perpendicularly extending from an end portion of the first portion  341  that faces the first optical axis direction {circle around ( 1 )}, and a third portion  343  perpendicularly extending from an end portion of the first portion  3412  that faces a second optical axis direction  2 . The second portion  342  and the third portion  343  may be extending in a vertical direction (e.g., z-axis direction) in relation to the electronic device  100  with a front surface facing the vertical direction. For example, the second portion  342  and the third portion  343  may extend from the first portion  341  toward a base  311  of the first housing  310 . In an embodiment, a first protruding portion  344  may be formed on the second portion  342 , and a second protruding portion  345  facing the first protruding portion  344  may be formed on the third portion  343 . For example, the first protruding portion  344  may protrude from a partial area of the second portion  342  in the second optical axis direction  2 . The second protruding portion  345  may protrude from a partial area of the third portion  343  in the first optical axis direction {circle around ( 1 )}. The first protruding portion  344  may be configured to make contact with the damping member  350  when the lens assembly  320  moves a predetermined distance in the second optical axis direction  2 . The second protruding portion  345  may be configured to make contact with the damping member  350  when the lens assembly  320  moves a predetermined distance in the first optical axis direction {circle around ( 1 )}. 
     In an embodiment, the damping member  350  may be configured to make contact with the first protruding portion  344  or the second protruding portion  345  of the support member  340  in response to a movement of the lens assembly  320 . The damping member  350  may be formed of a material capable of absorbing an impact when the first protruding portion  344  or the second protruding portion  345  makes contact with the damping member  350 . For example, the damping member  350  may contain an elastic material or a flexible material. For example, the damping member  350  may include a spring, sponge, Poron, rubber, or urethane. 
     In an embodiment, the damping member  350  may be disposed on a first sidewall  312  of the first housing  310 . For example, the first housing  310  may have, on the first sidewall  312  thereof, a damping member receiving part  317  in which the damping member  350  is accommodated. The damping member receiving part  317  may be formed in a hollow form such that the damping member  350  is accommodated inside and may include, in opposite side surfaces thereof, openings  318  through which the first protruding portion  344  and the second protruding portion  345  makes contact with the damping member  350 . 
     Referring to  FIG. 13A , the damping member  350  may include sponge, Poron, rubber, or urethane that has a predetermined shape. For example, the damping member  350  may be formed in a shape corresponding to the damping member receiving part  317 . At least parts of the damping member  350  may be exposed through the openings  318  of the damping member receiving part  317 . The first protruding portion  344  and the second protruding portion  345  may make contact with the damping member  350  through the openings  318 . 
     Referring to  FIG. 13B , the damping member  350  may include springs  351  and  352 . For example, the damping member  350  may be configured such that one end portion thereof is supported by a support wall  319  of the damping member receiving part  317 . For example, the damping member  350  may include the first spring and the second spring, each of which has one end portion supported by the support wall  319 . The first spring  351  may be disposed such that the one end portion is supported by the support wall  319  and the opposite end portion faces toward a corresponding one of the openings  318 . The second spring  352  may be disposed such that the one end portion is supported by the support wall  319  and the opposite end portion faces toward the other opening  318 . The first protruding portion  344  may make contact with the first spring  351  through the corresponding opening  318 . The second protruding portion  345  may make contact with the second spring  352  through the other opening  318 . 
     Hereinafter, operations of the support member  340  and the damping member  350  will be described with reference to  FIG. 14 . 
     The damping member  350  illustrated in  FIG. 14  may be referred to as the damping member illustrated in  FIG. 13A . However, the damping member  350  may include springs as illustrated in  FIG. 13B . 
     Referring to  FIG. 14 , as at least part of the support member  340  makes contact with the damping member  350 , the camera module  300  according to an embodiment may absorb an impact and/or noise caused by a movement of the lens assembly  320  at the same time as limiting a movement range of the lens assembly  320  in the direction of the optical axis L. 
     In an embodiment, when the lens assembly  320  moves in the first optical axis direction {circle around ( 1 )}, the second protruding portion  345  of the support member  340  may make contact with the damping member  350 . For example, when the lens assembly  320  moves a predetermined distance in the first optical axis direction {circle around ( 1 )}, the second protruding portion  345  may make contact with the damping member  350  and may restrict the lens assembly  320  from further moving in the first optical axis direction {circle around ( 1 )}. The damping member  350  formed of an elastic material or a flexible material may absorb an impact or noise when the second protruding portion  345  makes contact with the damping member  350 . 
     In an embodiment, when the lens assembly  320  moves in the second optical axis direction  2 , the first protruding portion  344  of the support member  340  may make contact with the damping member  350 . For example, when the lens assembly  320  moves a predetermined distance in the second optical axis direction  2 , the first protruding portion  344  may make contact with the damping member  350  and may restrict the lens assembly  320  from further moving in the second optical axis direction  2 . The damping member  350  formed of an elastic material or a flexible material may absorb an impact or noise when the first protruding portion  344  makes contact with the damping member  350 . 
     Referring to  FIG. 12 , the camera module  300  according to an embodiment may include the second stopper members  370 , in addition to the support member  340  and the damping member  350 . The second stopper members  370  (e.g., the linear stoppers  244  of the second stopper members  242  of  FIGS. 7 and 8 ), together with the support member  340  and the damping member  350 , may prevent a movement of the lens assembly  320  beyond a specified range in the second optical axis direction  2 . A first reflective member  331  may be disposed in the second optical axis direction  2  with respect to the lens assembly  320 , and when the lens assembly  320  excessively moves in the second optical axis direction  2 , the lens assembly  320  is likely to collide with the first reflective member  331  to cause damage to the first reflective member  331 . According to an embodiment, the camera module  300  may be configured to primarily limit a movement range of the lens assembly  320  in the second optical axis direction  2  through the support member  340  and the damping member  350  and secondarily limit the movement range of the lens assembly  320  in the second optical axis direction  2  through the second stopper members  370 . 
       FIG. 15  is a view illustrating the positions of sub-magnets  293  of the camera module  200  according to an embodiment.  FIG. 16  is a view illustrating operations of the sub-magnets  293  of the camera module  200  according to an embodiment. 
     Referring to  FIGS. 15 and 16 , the camera module  200  according to an embodiment may include the first housing  210 - 1 , the lens assembly  220 , the reflective member assembly  230 , the stopper members  241  and  242 , the second reflective member  291 , and the sub-magnets  293 . 
       FIGS. 15 and 16  are views illustrating an embodiment further including the sub-magnets  293  that generate repulsive forces with the first magnets  262  disposed on the lens assembly  220  in the camera module  200  illustrated in  FIGS. 4 to 8 . Some of the components of the camera module  200  illustrated in  FIGS. 15 and 16  are identical or similar to the components of the camera module  200  of  FIGS. 4 to 8 , and therefore repetitive descriptions will hereinafter be omitted. 
     In an embodiment, the first magnets  262  may be disposed on the lens assembly  220  to provide a driving force for a movement of the lens assembly  220  in the direction of the optical axis L. The first magnets  262  may be configured to electro-magnetically interact with the first coils (e.g., the first coils  261  of  FIG. 5 ). Although not illustrated, the first coils  261  may be located in the first opening area  2131  and the third opening area  2141  of the first housing  210 - 1  to face the first magnets  262 . 
     In an embodiment, the first magnets  262  may be disposed on side surfaces (e.g., the surfaces facing the y-axis direction) of the lens carrier  222  to face sidewalls (e.g., the first sidewall  213  and the second sidewall  214 ) of the first housing  210 - 1  that are parallel to the optical axis L. For example, the first magnets  262  may include a first sidewall magnet  263  facing the first sidewall  213  of the first housing  210 - 1  and a second sidewall magnet  264  facing the second sidewall  214  of the first housing  210 - 1 . For example, the first sidewall magnet  263  may partially overlap the first opening area  2131  of the first sidewall  213 . For example, the second sidewall magnet  264  may partially overlap the third opening area  2141  of the second sidewall  214 . 
     In an embodiment, the first magnets  262  may include first areas  263   a  and  264   a  having a first polarity and second areas  263   b  and  264   b  having a second polarity opposite to the first polarity. The first areas  263   a  and  264   a  and the second areas  263   b  and  264   b  may be arranged in the direction of the optical axis L. For example, the first areas  263   a  and  264   a  and the second areas  263   b  and  264   b  of the first magnets  262  may be arranged in the first optical axis direction {circle around ( 1 )}. For example, the first sidewall magnet  263  may be configured such that the first area  263   a  has an N pole and the second area  263   b  located in the first optical axis direction d from the first area  263   a  has an S pole. For example, the second sidewall magnet  264  may be configured such that the first area  264   a  has an S pole and the second area  264   b  located in the first optical axis direction d from the first area  264   a  has an N pole. However, the polarities of the first areas  263   a  and  264   a  and the second areas  263   b  and  264   b  are not limited to the illustrated embodiment. 
     In an embodiment, the sub-magnets  293  may interact with the first magnets  262  disposed on the lens assembly  220 . For example, the sub-magnets  293  may be configured to generate repulsive forces with the first magnets  262  and reduce the moving speed of the lens assembly  220  when the lens assembly  220  moves. 
     In an embodiment, the sub-magnets  293  may be disposed on sidewalls (e.g., the first sidewall  213  and the second sidewall  214 ) of the first housing  210 - 1  that face the first magnets  262 . The sub-magnets  293  may pass through at least parts of the first sidewall  213  and the second sidewall  214  to electro-magnetically interact with the first magnets  262 . For example, the sub-magnets  293  may include first sub-magnets  294  having the first polarity and second sub-magnets  295  that are spaced apart from the first sub-magnets  294  in the direction of the optical axis L and that have the second polarity opposite to the first polarity. 
     In an embodiment, the first sub-magnets  294  may be located in the second optical axis direction  3  with respect to the first magnets  262 , and the second sub-magnets  295  may be located in the first optical axis direction d with respect to the first magnets  262 . For example, the first sub-magnets  294  and the second sub-magnets  295  may be arranged in the direction of the optical axis L with the first opening area  2131  or the third opening area  2141  therebetween. When the first sidewall  213  or the second sidewall  214  of the first housing  210 - 1  is viewed in  FIG. 16 , the first sub-magnets  294 , the first areas  263   a  and  264   a  of the first magnets  262 , the second areas  263   b  and  264   b  of the first magnets  262 , and the second sub-magnets  295  may be arranged in the direction of the optical axis L. For example, the first sub-magnets  294 , the first areas  263   a  and  264   a  of the first magnets  262 , the second areas  263   b  and  264   b  of the first magnets  262 , and the second sub-magnets  295  may be sequentially arranged in the first optical axis direction {circle around ( 1 )}. 
     In an embodiment, the first sub-magnets  294  may interact with the first areas  263   a  and  264   a  of the first magnets  262 , and the second sub-magnets  295  may interact with the second areas  263   b  and  264   b  of the first magnets  262 . For example, the first sub-magnets  294  may be configured to have the same polarity as the first areas  263   a  and  264   a  to generate repulsive forces with the first areas  263   a  and  264   a  of the first magnets  262 . The second sub-magnets  295  may be configured to have the same polarity as the second areas  263  and  264   b  to generate repulsive forces with the second areas  263   b  and  264   b  of the first magnets  262 . 
     In an embodiment, the first sub-magnets  294  may include sub-magnet  1 - 1   294   a  disposed on the first sidewall  213  and sub-magnet  1 - 2   294   b  disposed on the second sidewall  214 . In an embodiment, the second sub-magnets  295  may include sub-magnet  2 - 1   295   a  disposed on the first sidewall  213  and sub-magnet  2 - 2   295   b  disposed on the second sidewall  214 . For example, sub-magnet  1 - 1   294   a  may have the same polarity (e.g., N pole) as the first area  263   a  of the first sidewall magnet  263 , and sub-magnet  1 - 2   294   b  may have the same polarity (e.g., S pole) as the first area  264   a  of the second sidewall magnet  264 . Furthermore, sub-magnet  2 - 1   295   a  may have the same polarity (e.g., S pole) as the second area  263   b  of the first sidewall magnet  263 , and sub-magnet  2 - 2   295   b  may have the same polarity (e.g., N pole) as the second area  264   b  of the second sidewall magnet  264 . 
     In an embodiment, when the lens assembly  220  moves in the first optical axis direction {circle around ( 1 )}, the second areas  263   b  and  264   b  of the first magnets  262  may move toward the second sub-magnets  295 , and repulsive forces may act therebetween. Due to the repulsive forces, a predetermined force may be applied to the lens assembly  220  in the second optical axis direction {circle around ( 3 )}, and therefore the moving speed in the first optical axis direction {circle around ( 1 )} may be reduced. When the lens assembly  220  moves a specified distance or more in the first optical axis direction {circle around ( 1 )}, the speed of the lens assembly  220  may be reduced by the repulsive forces before the lens assembly  220  makes contact with the first stopper member  241  (e.g., the linear stopper  244  of the first stopper member  241 ), and thus an impact and/or noise caused by the contact may be reduced. 
     In an embodiment, when the lens assembly  220  moves in the second optical axis direction  2 , the first areas  263   a  and  264   a  of the first magnets  262  may move toward the first sub-magnets  294 , and repulsive forces may act therebetween. Due to the repulsive forces, a predetermined force may be applied to the lens assembly  220  in the first optical axis direction {circle around ( 1 )}, and therefore the moving speed in the second optical axis direction  3  may be reduced. When the lens assembly  220  moves a specified distance or more in the second optical axis direction  2 , the speed of the lens assembly  220  may be reduced by the repulsive forces before the lens assembly  220  makes contact with the second stopper members  242  (e.g., the linear stoppers  244  of the second stopper members  242 ), and thus an impact and/or noise caused by the contact (or collision) may be reduced.

       FIGS. 17 and 18  illustrate the camera module  400  having a different structure from the camera module illustrated in  FIGS. 15 and 16  (e.g., the camera module  200  of  FIGS. 15 and 16 ). For example, the camera module  200  of  FIGS. 15 and 16  may be a camera module (a folded camera) in which the direction in which external light is incident on the camera module  200  and the optical axis of the lens are perpendicular to each other, and the camera module  400  of  FIGS. 17 and 18  may be a camera module (a direct type camera) in which the direction in which external light is incident on the camera module  400  and the optical axis of the lens are parallel to each other. 
     Referring to  FIG. 17 , the camera module  400  according to an embodiment may include a camera housing  410  (e.g., the camera housing  210  of  FIG. 4 ) and a camera assembly  430  (e.g., the lens assembly  220  of  FIG. 5 ), at least part of which is accommodated in the camera housing  410 . 
     In an embodiment, the camera housing  410  may include a base  411  and a cover  412  coupled to the base  411 . The base  411 , together with the cover  412 , may form an inner space of the camera housing  410  in which the camera assembly  430  is accommodated. For example, the base  411  may form the lower surface (e.g., the flat surface facing the −z-axis direction) of the camera module  400 , and the cover  412  may form the upper surface (e.g., the flat surface facing the +z-axis direction) of the camera module  400  and the side surfaces surrounding the upper surface and the lower surface. The cover  412  may have an opening  4121  formed therein through which a lens  431  and at least part of a lens barrel  432  are exposed. 
     In various embodiments, an image sensor (not illustrated) and a circuit board (not illustrated) that is electrically connected with the image sensor may be disposed on the base  411  of the camera housing  410 . In various embodiments, the image sensor may be disposed inside the camera housing  410  so as to be at least partially aligned with the optical axis L of the lens  431 . For example, the image sensor may convert an optical signal received through the lens  431  into an electrical signal. 
     In an embodiment, at least part of the camera assembly  430  may be accommodated in the camera housing  410 . The camera assembly  430  may be configured to move in the direction of the optical axis L of the lens inside the camera housing  410 . For example, when viewed in the X-Y-Z Cartesian coordinate system, the camera assembly  430  may linearly move in the z-axis direction (e.g., the +z/−z-axis directions) inside the camera housing  410 . In an embodiment, the camera module  400  may adjust (e.g., an auto focus (AF) function) the distance between the image sensor (not illustrated) fixedly disposed inside the camera housing  410  and the lens  431  included in the camera assembly  430  by moving the camera assembly  430  in the direction of the optical axis L. 
     In an embodiment, the camera assembly  430  may include one or more lenses  431  and the lens barrel  432  surrounding the one or more lenses  431 . In an embodiment, the camera assembly  430  may be disposed such that the lenses  431  and at least part of the lens barrel  432  are exposed through the opening  4121  formed in the cover  412  of the camera housing  410 . In an embodiment, the camera assembly  430  may be configured to receive light external to the electronic device  100  through a partial area of a surface of a housing (e.g., the housing  110  of  FIGS. 1 and 2 ) of an electronic device (e.g., the electronic device  100  of  FIGS. 1 to 3 ). In various embodiments, the camera assembly  430  may include a lens assembly (e.g., the lens assembly  220  of  FIG. 5 ) that includes the one or more lens  431  and the lens barrel  432 . 
     Referring to  FIG. 18 , the camera module  400  according to an embodiment may include a first magnet  460  providing a driving force for moving the camera assembly  430  in the direction of the optical axis L, a flexible circuit board  450  surrounding sidewalls of the camera housing  410 , and the sub-magnets  470  configured to generate a repulsive force with the first magnet  460 . 
     In an embodiment, side surfaces  441 ,  442 ,  443 , and  444  of the camera assembly  430  may be surrounded by the sidewalls  420  of the camera housing  410 . The first magnet  460  may be disposed on a part of the side surfaces  441 ,  442 ,  443 , and  444  of the camera assembly  430 . For example, the first magnet  460  may be disposed on the first side surface  441  of the camera assembly  430 . For example, the first side surface  441  of the camera assembly  430  may face a first sidewall  421  of the camera housing  410 . Although not illustrated, a first coil (not illustrated) that electro-magnetically interacts with the first magnet  460  may be disposed on the first sidewall  421 . For example, the first coil (not illustrated) may be disposed on the flexible circuit board  450  surrounding some of the sidewalls  420  of the camera housing  410  (e.g., the first sidewall  421 , the third sidewall  423 , and the fourth sidewall  424 ) and may be located to face the first magnet  460 . 
     In an embodiment, the camera assembly  430  may include, on the first side surface  441  thereof, a plurality of balls  433  that guide a movement of the camera assembly  430  in the direction of the optical axis L. For example, the plurality of balls  433  may be disposed between the first side surface  441  of the camera assembly  430  and the first sidewall  421  of the camera housing  410 . The plurality of balls  433  may be configured to roll in the space between the first sidewall  421  and the first side surface  441 . For example, when the camera assembly  430  moves in the direction of the optical axis L, the plurality of balls  433  may rotate while linearly moving between the camera assembly  430  and the camera housing  410 , or may rotate in position. 
     In an embodiment, the first magnet  460  may be disposed on the first side surface  441  of the camera assembly  430 . The first magnet  460  may include a first area  461  having a first polarity and a second area  462  having a second polarity opposite to the first polarity. The first area  461  and the second area  462  may be arranged in the direction of the optical axis L. 
     In an embodiment, the sub-magnets  470  may interact with the first magnet  460  disposed on the camera assembly  430 . For example, the sub-magnets  470  may be configured to generate a repulsive force with the first magnet  460  and reduce the moving speed of the camera assembly  430  when the camera assembly  430  moves in the direction of the optical axis L. For example, the sub-magnets  470  may be disposed on the first sidewall  421  of the camera housing  410  to interact with the first magnet  460 . 
     In an embodiment, the sub-magnets  470  may include a first sub-magnet  471  having the first polarity and a second sub-magnet  472  that is spaced apart from the first sub-magnet  471  in the direction of the optical axis L and that has the second polarity opposite to the first polarity. For example, the first sub-magnet  471  may be located in a first direction (e.g., +L direction) with respect to the first magnet  460 , and the second sub-magnet  472  may be located in the direction (e.g., −L direction) opposite to the first direction with respect to the first magnet  460 . For example, the first sub-magnet  471 , the first magnet  460 , and the second sub-magnet  472  may be arranged in the direction of the optical axis L. 
     In an embodiment, the first sub-magnet  471  may interact with the first area  461  of the first magnet  460 , and the second sub-magnet  472  may interact with the second area  462  of the first magnet  460 . For example, the first sub-magnet  471  may be configured to have the same polarity as the first area  461  to generate a repulsive force with the first area  461  of the first magnet  460 . The second sub-magnet  472  may be configured to have the same polarity as the second area  462  to generate a repulsive force with the second area  462  of the first magnet  460 . 
     In an embodiment, when the camera assembly  430  moves in the first direction (e.g., the +L direction or the +z-axis direction), the first area  461  of the first magnet  460  may move toward the first sub-magnet  471 , and a repulsive force may act therebetween. Due to the repulsive force, a predetermined force may be applied to the camera assembly  430  in the direction (e.g., the −L direction or the −z-axis direction) opposite to the first direction, and therefore the speed of the camera assembly  430  may be reduced. 
     In an embodiment, when the camera assembly  430  moves in the second direction (e.g., the −L direction or the −z-axis direction) opposite to the first direction, the second area  462  of the first magnet  460  may move toward the second sub-magnet  472 , and a repulsive force may act therebetween. Due to the repulsive force, a predetermined force may be applied to the camera assembly  430  in the first direction (e.g., the +L direction or the +z-axis direction), and therefore the speed of the camera assembly  430  may be reduced

       FIG. 20  is a block diagram  600  illustrating the camera module  580  according to various embodiments. 
     Referring to  FIG. 20 , the camera module  580  may include a lens assembly  610 , a flash  620 , an image sensor  630 , an image stabilizer  640 , memory  650  (e.g., buffer memory), or an image signal processor  660 . The lens assembly  610  may collect light emitted or reflected from an object whose image is to be taken. The lens assembly  610  may include one or more lenses. According to an embodiment, the camera module  580  may include a plurality of lens assemblies  610 . In such a case, the camera module  580  may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies  610  may have the same lens attribute (e.g., view angle, focal length, auto-focusing, f number, or optical zoom), or at least one lens assembly may have one or more lens attributes different from those of another lens assembly. The lens assembly  610  may include, for example, a wide-angle lens or a telephoto lens. 
     The flash  620  may emit light that is used to reinforce light reflected from an object. According to an embodiment, the flash  620  may include one or more light emitting diodes (LEDs) (e.g., a red-green-blue (RGB) LED, a white LED, an infrared (IR) LED, or an ultraviolet (UV) LED) or a xenon lamp. The image sensor  630  may obtain an image corresponding to an object by converting light emitted or reflected from the object and transmitted via the lens assembly  610  into an electrical signal. According to an embodiment, the image sensor  630  may include one selected from image sensors having different attributes, such as a RGB sensor, a black-and-white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same attribute, or a plurality of image sensors having different attributes. Each image sensor included in the image sensor  630  may be implemented using, for example, a charged coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor. 
     The image stabilizer  640  may move the image sensor  630  or at least one lens included in the lens assembly  610  in a particular direction, or control an operational attribute (e.g., adjust the read-out timing) of the image sensor  630  in response to the movement of the camera module  580  or the electronic device  501  including the camera module  580 . This allows compensating for at least part of a negative effect (e.g., image blurring) by the movement on an image being captured. According to an embodiment, the image stabilizer  640  may sense such a movement by the camera module  580  or the electronic device  501  using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module  580 . According to an embodiment, the image stabilizer  640  may be implemented, for example, as an optical image stabilizer. The memory  650  may store, at least temporarily, at least part of an image obtained via the image sensor  630  for a subsequent image processing task. For example, if image capturing is delayed due to shutter lag or multiple images are quickly captured, a raw image obtained (e.g., a Bayer-patterned image, a high-resolution image) may be stored in the memory  650 , and its corresponding copy image (e.g., a low-resolution image) may be previewed via the display module  560 . Thereafter, if a specified condition is met (e.g., by a user&#39;s input or system command), at least part of the raw image stored in the memory  650  may be obtained and processed, for example, by the image signal processor  660 . According to an embodiment, the memory  650  may be configured as at least part of the memory  530  or as a separate memory that is operated independently from the memory  530 . 
     The image signal processor  660  may perform one or more image processing with respect to an image obtained via the image sensor  630  or an image stored in the memory  650 . The one or more image processing may include, for example, depth map generation, three-dimensional (3D) modeling, panorama generation, feature point extraction, image synthesizing, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor  660  may perform control (e.g., exposure time control or read-out timing control) with respect to at least one (e.g., the image sensor  630 ) of the components included in the camera module  580 . An image processed by the image signal processor  660  may be stored back in the memory  650  for further processing, or may be provided to an external component (e.g., the memory  530 , the display module  560 , the electronic device  502 , the electronic device  504 , or the server  508 ) outside the camera module  580 . According to an embodiment, the image signal processor  660  may be configured as at least part of the processor  520 , or as a separate processor that is operated independently from the processor  520 . If the image signal processor  660  is configured as a separate processor from the processor  520 , at least one image processed by the image signal processor  660  may be displayed, by the processor  520 , via the display module  560  as it is or after being further processed.
