[0077] FIG. 2 is a block diagram illustrating a camera module according to one embodiment.
[0078] Referring to FIG. 2, the camera module (180) may include a lens assembly (210), a flash (220), an image sensor (230), an image stabilizer (240), a memory (250) (e.g., a buffer memory), or an image signal processor (260). The lens assembly (210) may collect light emitted from a subject that is a target of image capturing. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera module (180) may include a plurality of lens assemblies (210). In this case, the camera module (180) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies (210) may have the same lens properties (e.g., angle of view, focal length, autofocus, f-number, or optical zoom), or at least one lens assembly may have one or more lens properties that are different from the lens properties of the other lens assemblies. A lens assembly (210) may include, for example, a wide-angle lens or a telephoto lens.
[0079] The flash (220) can emit light used to enhance light emitted or reflected from a subject. According to one embodiment, the flash (220) can include one or more light-emitting diodes (e.g., red-green-blue (RGB) LED, white LED, infrared LED, or ultraviolet LED), or a xenon lamp. The image sensor (230) can acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through the lens assembly (210) into an electrical signal. According to one embodiment, the image sensor (230) can include one image sensor selected from among image sensors having different properties, such as an RGB sensor, a black and white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same property, or a plurality of image sensors having different properties. Each image sensor included in the image sensor (230) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.
[0080] The image stabilizer (240) can move at least one lens or image sensor (230) included in the lens assembly (210) in a specific direction or control the operating characteristics of the image sensor (230) (e.g., adjusting the read-out timing, etc.) in response to the movement of the camera module (180) or the electronic device (101) including the same. This allows compensating for at least some of the negative effects of the movement on the captured image. In one embodiment, the image stabilizer (240) can detect such movement of the camera module (180) or the electronic device (101) by using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module (180). In one embodiment, the image stabilizer (240) can be implemented as, for example, an optical image stabilizer. The memory (250) can temporarily store at least a portion of the image acquired through the image sensor (230) for the next image processing task. For example, when image acquisition is delayed due to the shutter, or when multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in the memory (250), and a corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Thereafter, when a specified condition is satisfied (e.g., a user input or a system command), at least a portion of the original image stored in the memory (250) can be acquired and processed, for example, by the image signal processor (260). According to one embodiment, the memory (250) can be configured as at least a portion of the memory (130) or as a separate memory that operates independently therefrom.
[0081] The image signal processor (260) can perform one or more image processing operations on an image acquired through an image sensor (230) or an image stored in a memory (250). The one or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature point extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor (260) may perform control (e.g., exposure time control, read-out timing control, etc.) on at least one of the components included in the camera module (180) (e.g., image sensor (230)). An image processed by the image signal processor (260) may be stored back in the memory (250) for further processing or provided to an external component of the camera module (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108)). According to one embodiment, the image signal processor (260) may include at least one of the processors (120). It may be configured as a separate processor that is configured as a part of the processor (120) or operates independently of the processor (120). If the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (160) as is or after undergoing additional image processing by the processor (120).
[0082] According to one embodiment, the electronic device (101) may include a plurality of camera modules (180), each having different properties or functions. In this case, for example, at least one of the plurality of camera modules (180) may be a wide-angle camera, and at least another may be a telephoto camera. Similarly, at least one of the plurality of camera modules (180) may be a front camera, and at least another may be a rear camera.

At least a portion of the bending region B13 may be substantially aligned with a corner region of the image sensor (431) (e.g., a corner region between a -Y direction edge and a +X direction edge) in the first optical axis direction (e.g., +Z direction). The bending region B13 may be connected to the side region T13.
[0119] The first branch (433A) may include a side region T14 that is substantially orthogonal to the first optical axis direction (e.g., +Z direction) and the extension direction of the side region T13 (e.g., +X direction) and extends in a direction opposite to the extension direction of the side region T12 (e.g., -Y direction) (e.g., +Y direction).

The side region T14 may be arranged opposite to the side region T12.
[0120] The first branch (433A) may include a folding region F12 folded in a second optical axis direction (e.g., -Z direction) opposite to the first optical axis direction (e.g., +Z direction). The folding region F12 may be a region bent outwardly with respect to the side region T14 at a second angle (e.g., about 45 degrees) less than the first angle and folded at a third angle (e.g., about 180 degrees) greater than the first angle in the second optical axis direction (e.g., -Z direction). In one embodiment, the folding region F12 may be a region bent inwardly with respect to the side region T14 at a second angle and folded at a third angle in the second optical axis direction (e.g., -Z direction).

The bending area B21 may be directly connected to the image sensor (431). The bending area B21 may be separated from the bending area B11 along an edge (e.g., -X direction edge) of the image sensor (431). In one embodiment, the second branch (433B) may include an additional area between the image sensor (431) and the bending area B21. The additional area may be referred to as a “base area.” The additional area may connect the bending area B11 and the bending area B21. The additional area may be substantially on the same plane as the image sensor (431).
[0125] The second branch (433B) may include a side region T21 extending substantially in the first optical axis direction (e.g., +Z direction). The side region T21 may be connected to the bending region B21.
[0126] The second branch (433B) may include a folding region F21 folded in a direction (e.g., +Y direction) substantially orthogonal to the first optical axis direction (e.g., +Z direction). The folding region F21 may be a region bent inwardly with respect to the side region T21 at a second angle (e.g., about 45 degrees) that is less than the first angle and folded in a direction (e.g., +Y direction) at a third angle (e.g., about 180 degrees) that is greater than the first angle. In one embodiment, the folding region F21 may be a region bent outwardly with respect to the side region T21 at a second angle and folded in a direction (e.g., +Y direction) at a third angle. The folding region F21 may be directly connected to the side region T21. In one embodiment, the folding region F21 may be directly connected to the bending region B21 without the side region T21.
[0127] The second branch (433B) may include a side region T22 extending in one direction (e.g., +Y direction). The side region T22 may extend along a portion of the perimeter of the image sensor (431) (e.g., -X direction edge). The side region T22 may be connected to the folding region F21.
[0128] The second branch (433B) may include a bending region B22 bent in a direction (e.g., +X direction) substantially orthogonal to the first optical axis direction (e.g., +Z direction) and the extension direction (e.g., +Y direction) of the side region T22.

[0129] The second branch (433B) may include a side region T23 extending in a direction (e.g., +X direction) substantially orthogonal to the first optical axis direction (e.g., +Z direction) and the extension direction (e.g., +Y direction) of the side region T22.

[0130] The second branch (433B) may include a bending region B23 bent in a direction (e.g., -Y direction) substantially orthogonal to the first optical axis direction (e.g., +Z direction) and the extension direction (e.g., +X direction) of the side region T23. The bending region B23 may be a region bent at a first angle (e.g., about 90 degrees) with respect to the side region T23. At least a portion of the bending region B23 may be substantially aligned with a corner region of the image sensor (431) (e.g., a corner region between a +Y direction edge and a +X direction edge) in the first optical axis direction (e.g., +Z direction). The bending region B23 may be connected to the side region T23.
[0131] The second branch (433B) may include a side region T24 that is substantially orthogonal to the first optical axis direction (e.g., +Z direction) and the extension direction of the side region T23 (e.g., +X direction) and extends in a direction opposite to the extension direction of the side region T22 (e.g., -Y direction). The side region T24 may extend along a portion of the periphery of the image sensor (431) (e.g., +X direction edge). The side region T24 may be connected to the bending region B23. The side region T24 may be arranged opposite to the side region T22.
[0132] The second branch (433B) may include a folding region F22 folded in a second optical axis direction (e.g., -Z direction) opposite to the first optical axis direction (e.g., +Z direction). The folding region F22 may be a region bent outwardly with respect to the side region T24 at a second angle (e.g., about 45 degrees) that is smaller than the first angle and folded at a third angle (e.g., about 180 degrees) that is larger than the first angle in the second optical axis direction (e.g., -Z direction). In one embodiment, the folding region F22 may be a region bent inwardly with respect to the side region T24 at a second angle and folded at a third angle in the second optical axis direction (e.g., -Z direction).
[0133] The second branch (433B) may include a side region T25 extending substantially in the second optical axis direction (e.g., -Z direction). The side region T25 may be connected to the folding region F22.
[0134] The second branch (433B) may include a bending area B24 bent in an outward direction (e.g., +X direction) of the image sensor (431) at a first angle (e.g., about 90 degrees) with respect to the second optical axis direction (e.g., -Z direction). The bending area B24 may be an area bent toward the connector (432).
[0135] The second prong (433B) may include a base region T26 connecting the bend region B24 and the connector (432). The base region T26 may be substantially coplanar with the connector (432). The base region T26 may be a single region integrated with the base region T16. The base region T26 may be connected to a portion of the first prong (433A), such as the bend region B14. In one embodiment, the bend region B24 may be directly connected to the connector (432) without the base region T26. In one embodiment, the base region T16 and the base region T26 may be distinct and separate from each other.
[0136] Folding area F11, folding area F12, folding area F21, and folding area F22 may have a curvature that does not cause cracks. For example, folding area F11, folding area F12, folding area F21, and folding area F22 may have a curvature radius of approximately 1 mm. The curvature radii of the folding areas may vary depending on the shape of the FPCB, the type of camera module, or other design parameters.
[0137] The first branch (433A) and the second branch (433B) may be substantially symmetrical with respect to a plane (e.g., an XZ plane) that includes a first optical axis direction (e.g., a +Z direction) and is substantially orthogonal to a plane (e.g., an XY plane) on which the image sensor (431) is placed. For example, side regions T12 and T22 may extend in opposite directions, side regions T13 and T23 may be substantially parallel to each other, and side regions T14 and T24 may extend in opposite directions.
[0138] The connecting assembly (430) may include an FPCB (433) including various combinations of the first prong (433A) and the second prong (433B). For example, a combination of any one of the inner folding and the outer folding of the folding area F11, any one of the inner folding and the outer folding of the folding area F21, any one of the inner folding and the outer folding of the folding area F12, and any one of the inner folding and the outer folding of the folding area F22 is possible.
[0139] In one embodiment, the FPCB (433) may include only one of the first prong (433A) and the second prong (433B).
[0140] Bending area B11, bending area B21, bending area B14, and bending area B24 can enable a design in which areas of the FPCB (433) that can be moved by receiving force (e.g., side area T12, side area T22, side area T13, side area T23, side area T14, and side area T24) are placed on a different plane from the plane on which the image sensor (431) and / or the connector (432) are placed. This can increase the placement efficiency of the connecting assembly (430), and thus reduce the size of the module (e.g., the camera module (400) of FIGS. 5 to 7).
[0141] Areas of the FPCB (433) that are on a different plane from the plane on which the image sensor (431) and / or the connector (432) are placed (e.g., side area T12, side area T22, side area T13, side area T23, side area T14, and side area T24) can achieve a desired displacement with reduced driving force, which can reduce the power required for driving.
[0142] The FPCB (433) including multiple bending regions has a reduced elastic modulus, which can distribute force across multiple regions of the FPCB (433) to reduce the power required for driving.
[0143] The connecting assembly (430) may include a plurality of reinforcing members (434). Each reinforcing member (434) may make the stiffness of an area of the FPCB (433) to which the reinforcing member (434) is applied greater than the stiffness of an area of the FPCB (433) to which the reinforcing member (434) is not applied. For example, the plurality of reinforcing members (434) may be applied to bending area B11, bending area B21, bending area B12, bending area B23, bending area B14, and bending area B24. A displacement (e.g., a displacement on the XY plane) of at least one area (e.g., a side area T12 and a side area T13) of the FPCB (433) surrounding the bending area (e.g., a bending area B12) of the FPCB (433) to which the reinforcing member (434) is applied may be achieved.
[0144] FIG. 10 is a drawing showing a bending area of a flexible printed circuit board (FPCB) according to one embodiment.
[0145] Referring to FIG. 10, the connecting assembly (430) may include an FPCB (433). The FPCB (433) may include a first side region (T1) extending in a first direction (e.g., + / - Y direction), a second side region (T2) extending in a second direction (e.g., + / - X direction) different from the first direction (e.g., substantially orthogonal), and a bending region (B) connecting the first side region (T1) and the second side region (T2) and being bent relative to the first side region (T1) and the second side region (T2). The first side region (T1), the second side region (T2), and the bending region (B) may be applied to the side regions and the bending region therebetween described with reference to FIGS. 8 and 9.
[0146] The connecting assembly (430) may include a reinforcing member (434). The reinforcing member (434) may increase the rigidity of the bending region (B) to a greater extent than the rigidity of other regions (e.g., the first side region (T1) and / or the second side region (T2)). The reinforcing member (434) may include a material having a rigidity greater than the rigidity of the FPCB (433). The reinforcing member (434) may be secured to the outer surface of the bending region (B) by any suitable bonding means (e.g., double-sided tape). The reinforcing member (434) may allow the shape of the FPCB (433) to change consistently.
[0147] In an embodiment where the FPCB (433) includes a plurality of bending areas (B), the reinforcement (434) may be applied to at least some of the bending areas (B). For example, referring to FIGS. 8 and 9 , the reinforcement (434) may be applied to bending areas B11, B21, B12, and B23. The side areas on both sides of the bending area to which the reinforcement (434) is applied may be displaced or shifted relative to the bending area therebetween. In one embodiment, there may be a greater number of reinforcements (434) that may be applied to the bending areas, as long as they do not affect the tension of the FPCB (433) beyond a desired range.
[0148] In one embodiment, the increase in stiffness of the bending region (B) may also be achieved by other structures without the reinforcement (434). For example, a portion of the housing (420) that contacts the bending region (B) (e.g., an inner corner region of the enclosure (420B)) may guide and support the bending region (B).
[0149] Fig. 11 is a drawing showing a folding area of an FPCB according to one embodiment.
[0150] Referring to FIG. 11, the connecting assembly (430) may include an FPCB (433). The FPCB (433) may include a first side region (T1) extending in a first direction (e.g., + / - Z direction), a second side region (T2) extending in a second direction (e.g., + / - Y direction) different from the first direction (e.g., substantially orthogonal), and a folding region (F) connecting the first side region (T1) and the second side region (T2) and folded relative to the first side region (T1) and the second side region (T2). The folding region (F) may be applied to the folding regions (e.g., F11, F12, F21, and / or F22) described with reference to FIGS. 8 and 9.
[0151] The connecting assembly (430) may include a fixing member (435) configured to maintain the shape of the folding area (F). The fixing member (435) may include a multi-stage shape surrounding the inner and / or outer surfaces of the folding area (F). For example, the fixing member (435) may include a clip.
[0152] In one embodiment, the connecting assembly (430) may include a bonding member. The bonding member may be applied to the inner surface of the folding area (F). The bonding member may be cured to maintain the shape of the folding area (F) while the folding area (F) of the FPCB (433) is secured by any suitable securing means. Once the bonding member is cured, the securing means may be removed.
[0153] Fig. 12 is a perspective view of a connecting assembly before a portion of an FPCB is bent / folded according to an embodiment. Fig. 13 is a perspective view of a connecting assembly of Fig. 12 according to an embodiment, in which a portion of an FPCB is bent. Fig. 14 is a perspective view of a connecting assembly of Fig. 13 according to an embodiment, in which a portion of an FPCB is bent / folded. Fig. 15 is a plan view of a connecting assembly of Fig. 14 according to an embodiment, in which a portion of an FPCB is bent.
[0154] The connecting assembly (430) illustrated in FIG. 12 can be transitioned to the connecting assembly (430) of FIG. 13 by bending (e.g., bending about 90 degrees) side area T12 relative to side area T13 relative to bend area B12 of the FPCB (433), by bending (e.g., bending about 90 degrees) side area T13 relative to side area T13 relative to bend area B13 of the FPCB (433), by bending (e.g., bending about 90 degrees) side area T22 relative to side area T23 relative to bend area B22 of the FPCB (433), and by bending (e.g., bending about 90 degrees) side area T24 relative to side area T23 relative to bend area B23 of the FPCB (433).
[0155] The connecting assembly (430) illustrated in FIG. 13 can be transferred to the connecting assembly (430) of FIG. 14 by folding the side area T12 and the side area T14 inwardly (e.g., bending about 45 degrees and then folding about 180 degrees) based on the folding area F11 and the folding area F12 of the FPCB (433), respectively, and by folding the side area T22 and the side area T24 inwardly (e.g., bending about 45 degrees and then folding about 180 degrees) based on the folding area F21 and the folding area F22 of the FPCB (433), respectively.
[0156] The connecting assembly (430) illustrated in FIG. 14 can be converted to the connecting assembly (430) of FIG. 15 by bending the image sensor (431) (e.g., bending at about 90 degrees) based on the bending area B11 and the bending area B21 of the FPCB (433), and by bending the connector (432) or the base area T16 connected thereto (e.g., bending at about 90 degrees) based on the bending area B14 and the bending area B24 of the FPCB (433).
[0157] FIG. 16 is a plan view of a connecting assembly showing an FPCB displaced in one direction according to one embodiment. FIG. 17 is a plan view of a connecting assembly showing an FPCB displaced in another direction according to one embodiment.
[0158] Referring to FIG. 16, the connector (432) in the connecting assembly (430) can be maintained in a fixed state. When a force in the -X direction is applied to the side regions T12 and / or T22 in the + / -X direction among the side regions of the FPCB (433) (for example, by an external force or an actuator (440) described with reference to FIGS. 5 to 7), the side regions T12 and T13 receive a force that moves in the -X direction, and the side regions T12 and T22 are bent (deflected) with respect to the side regions T13 and T23, respectively, with respect to the bending regions B12 and B22, and the image sensor (431) can be shifted in the -X direction. Similarly, when a force in the +X direction is applied to the side regions T12 and / or T22 in the + / -X direction, the image sensor (431) can be shifted in the +X direction.
[0159] Referring to FIG. 17, the connector (432) in the connecting assembly (430) can be maintained in a fixed state. When a force in the -Y direction is applied to the side regions T13 and / or T23 in the + / -Y direction among the side regions of the FPCB (433) (for example, by an external force or an actuator (440) described with reference to FIGS. 5 to 7), the side regions T13 and T23 receive a force that moves in the -Y direction, and the side regions T13 and T23 are bent with respect to the side regions T14 and T24, respectively, with respect to the bending regions B13 and B23, and the image sensor (431) can be shifted in the -Y direction. Similarly, when a force in the +Y direction is applied to the side regions T13 and / or T23 in the + / -Y direction, the image sensor (431) can be shifted in the +Y direction.
[0160] As described with reference to FIGS. 16 and 17, applying force to the side regions T12, T22, T13 and / or T23 can reduce the repulsive force of the FPCB (433).
