Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims the benefit of priority from Korean Patent Application No. 10-2021-0014264 filed in the Korean Intellectual Property Office on February 1, 2021, the disclosure of which is incorporated herein in its entirety for all purposes. Technical Field

[0003] The following description relates to a camera module, and, for example, to a camera module having an improved optical image stabilization function. Background Art

[0004] Camera modules are generally used in mobile communication terminals such as smart phones, tablet PCs, and laptop computers.

[0005] A camera module for a mobile communication terminal may include an actuator configured to move a lens module for focus adjustment and optical image stabilization, and generally, the actuator may move the lens module in an optical axis direction and in a direction perpendicular to the optical axis by a driving force of a magnet and a coil. However, since jitter generated in a camera module may not always occur in a direction perpendicular to the optical axis, there may be a limitation on optical image stabilization when the lens module moves in a direction perpendicular to the optical axis.

[0006] Furthermore, when shaking occurs continuously, such as when shooting a video, it may be difficult to accurately correct the shaking. In addition, when the object to be imaged moves during video shooting, the user may have to directly move the mobile communication terminal to adjust the imaging direction of the camera module to match the moving object. Summary of the invention

[0007] The present summary is provided to introduce a selection of inventive concepts in a concise form, and these inventive concepts will be further described in the following detailed description. The present summary is not intended to identify the key features or essential features of the claimed subject matter, nor is it intended to be used to help determine the scope of the claimed subject matter.

[0008] In one general aspect, a camera module includes: a housing; an optical assembly configured to be tilted relative to the housing and including a lens system and a sensor substrate having an image sensor; a main substrate disposed in the housing and spaced apart from the sensor substrate; and a first flexible substrate and a second flexible substrate configured to connect the sensor substrate to the main substrate.

[0011] The edge of the sensor substrate may include a first edge extending in a first direction perpendicular to the optical axis. The first portion of the first flexible substrate may extend outwardly from a portion of the first edge and extend in the first direction. A portion of the second flexible substrate may extend outwardly from another portion of the first edge and extend in a second direction opposite to the first direction, and may overlap at least a portion of the first portion of the first flexible substrate.

[0012] The first flexible substrate may extend around a perimeter of the sensor substrate in a counterclockwise direction relative to the optical axis, and the second flexible substrate may extend around a perimeter of the sensor substrate in a clockwise direction relative to the optical axis.

The optical assembly is configured to be tilted relative to the housing, relative to a first axis and a second axis, and the first axis and the second axis are perpendicular to the optical axis and intersect each other. The sensor substrate includes an edge, which includes a first edge and a second edge opposite to each other. The first edge extends from a first end to a second end in a first direction. The second edge extends from a third end to a fourth end in the first direction.

[0041] Throughout the drawings and detailed description, the same reference numerals will be understood to refer to the same elements, features, and structures. For purposes of clarity, illustration, and convenience, the drawings may not be drawn to scale, and the relative sizes, proportions, and depictions of elements in the drawings may be exaggerated. DETAILED DESCRIPTION

[0042] The following specific embodiments are provided to help the reader obtain a comprehensive understanding of the method, device and / or system described herein. However, various changes, modifications and equivalents of the method, device and / or system described herein will be apparent after understanding the disclosure of the application. For example, except for the operations that must occur in a specific order, the order of the operations described herein is merely an example, and is not limited to the order set forth in this article, but changes that will be apparent after obtaining an understanding of the disclosure of the application can be made. In addition, for greater clarity and brevity, the description of features known in the art may be omitted.

[0043] The features described herein may be implemented in different forms and should not be construed as being limited to the examples described herein. Rather, the examples described herein are provided only to illustrate some of the many possible ways to implement the methods, devices and / or systems described herein that will be apparent after understanding the disclosure of the present application.

[0044] Herein, it should be noted that the use of the term "may" with respect to an embodiment or example (e.g., with respect to what an embodiment or example may include or implement) means that there is at least one embodiment or example that includes or implements such feature, but all embodiments and examples are not limited thereto.

[0045] Throughout the specification, when an element such as a layer, a region, or a substrate is described as being “on,” “connected to,” or “coupled to” another element, the element may be directly “on,” “connected to,” or “coupled to” another element, or one or more other elements may be present between the element and the other element. Conversely, when an element is described as being “directly on,” “directly connected to,” or “directly coupled to” another element, no other elements may be present between the element and the other element.

[0046] As used herein, the term "and / or" includes any one of the associated listed items and any combination of any two or more items.

[0047] Although terms such as "first", "second" and "third" may be used herein to describe various components, parts, regions, layers or portions, these components, parts, regions, layers or portions are not limited by these terms. Rather, these terms are only used to distinguish one component, part, region, layer or portion from another component, part, region, layer or portion. Therefore, without departing from the teachings of the examples described herein, the first component, first component, first region, first layer or first portion mentioned in the examples may also be referred to as the second component, second component, second region, second layer or second portion.

[0048] Spatially relative terms such as "above", "higher", "below", and "lower" may be used herein for descriptive convenience to describe the relationship of one element relative to another element as shown in the accompanying drawings. In addition to covering the orientations depicted in the accompanying drawings, these spatially relative terms are intended to also cover different orientations of the device in use or operation. For example, if the device in the accompanying drawings is flipped, an element described as being "above" or "higher" relative to another element will be "below" or "lower" relative to the other element. Therefore, depending on the spatial orientation of the device, the term "above" covers both "above" and "below" orientations. The device may also be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatially relative terms used herein should be interpreted accordingly.

[0049] The terms used herein are only used to describe various examples and are not intended to limit the present disclosure. Unless the context clearly indicates otherwise, the articles "a", "an" and "the" are intended to include plural forms as well. The words "include", "comprise" and "have" illustrate the presence of stated features, numbers, operations, components, elements and / or combinations thereof, but do not exclude the presence or addition of one or more other features, numbers, operations, components, elements and / or combinations thereof.

[0050] Due to manufacturing techniques and / or tolerances, the shapes shown in the drawings may vary. Therefore, the examples described herein are not limited to the specific shapes shown in the drawings but include shape variations that occur during manufacturing.

[0051] The features of the examples described herein can be combined in various ways that will be apparent after understanding the present disclosure. In addition, although the examples described herein have multiple configurations, it will be apparent after understanding the present disclosure that other configurations are also possible.

[0052] Figure 1 is a diagram showing a camera module 1 according to an embodiment. Figure 2 is an exploded perspective view showing a camera module 1 according to an embodiment. Figure 3 is a diagram showing a camera module 1 viewed from above according to an exemplary embodiment.

[0053] refer to Figure 1 and Figure 2 , the camera module 1 may include a housing 100 and an optical assembly 200 disposed in the housing 100. The optical assembly 200 may include a lens system and an image sensor 230. The optical assembly 200 may include a driver therein configured to move the lens assembly or the image sensor 230. The optical assembly 200 may include a sensor substrate 210 on which the image sensor 230 is mounted, and the sensor substrate 210 may form the bottom of the optical assembly 200.

[0054] The sensor substrate 210 may be electrically connected to the main substrate 300. The flexible substrate 400 may electrically connect the sensor substrate 210 to the main substrate 300. A signal output by the image sensor 230 may be transmitted to the main substrate 300 through a wiring included in the flexible substrate 400, or power may be supplied to the sensor substrate 210 through a wiring included in the flexible substrate 400. The main substrate 300 may be connected to the connector 350 through the extension portion 330, and may communicate with an external electronic circuit of the camera module 1 through the connector 350.

[0055] The sensor substrate 210 may be disposed in a space 320 surrounded by an inner edge 310 of the main substrate 300. In an example, the flexible substrate 400 may be drawn out from a portion of the edge of the sensor substrate 210 and may extend to the main substrate 300. A plurality of flexible substrates 400 may be provided, and the plurality of flexible substrates 400 may connect the sensor substrate 210 to the main substrate 300. For example, the image sensor 230 may include a plurality of terminals, and a portion of the plurality of terminals may be connected to the sensor substrate 210 through a first flexible substrate 410 ( Figure 4) is connected to the main substrate 300, and another part of the plurality of terminals may be connected to the main substrate 300 through the second flexible substrate 420 ( Figure 4 ) is connected to the main substrate 300. Figures 4 to 14 The structure of the flexible substrate 400 connecting the sensor substrate 210 to the flexible substrate 400 is described in more detail.

[0056] In an example, the camera module 1 may have an optical image stabilization function. In an example, the optical assembly 200 may be tilted relative to an axis perpendicular to the optical axis O and relative to the housing 100 .

[0057] In an example, the camera module 1 may include a first frame 500 configured to be tilted relative to the first axis A1 and relative to the housing 100. In an example, a first ball member B1 may be inserted between the housing 100 and the first frame 500. For example, the first ball member B1 may be disposed between the first groove 101 formed on the surface of the housing 100 and the first frame 500. Figure 3 , the first ball member B1 may be arranged along the first axis A1, and the first frame 500 may rotate within a predetermined range relative to the first axis A1 and relative to the housing 100.

[0058] In an example, the camera module 1 may include a second frame 600 configured to be tilted relative to the second axis A2 and relative to the first frame 500. In an example, a second ball member B2 may be inserted between the first frame 500 and the second frame 600. For example, the second ball member B2 may be disposed between the second groove 501 formed in the surface of the first frame 500 and the second frame 600. Figure 3 , the second ball member B2 may be arranged along the second axis A2, and the second frame 600 may rotate within a predetermined range relative to the second axis A2 and relative to the first frame 500.

[0059] In an exemplary embodiment, the camera module 1 may include a driver for optical image stabilization. The driver may include a first magnet 711 and a second magnet 712 disposed in the second frame 600, and a first coil 721 and a second coil 722 disposed in the housing 100. For example, in the second frame 600, the first magnet 711 may be attached to a first surface 601 extending in the Y direction (disposed in the YZ plane), and the second magnet 712 may be attached to a second surface 602 extending in the X direction (disposed in the XZ plane). The first coil 721 and the second coil 722 may be fastened to the housing 100 to be opposite to the first magnet 711 and the second magnet 712 through the openings 102 and 103, respectively. For example, the first coil 721 and the second coil 722 may be attached to substrates 731 and 732, respectively, and the substrates 731 and 732 may be attached to the housing 100, so that the first coil 721 and the second coil 722 may be fastened to the housing 100. The optical assembly 200 may rotate relative to the housing 100 around an axis perpendicular to the optical axis O through electromagnetic interactions between the first coil 721 and the second coil 722 and the first magnet 711 and the second magnet 712 , respectively.

[0060] In an example, the camera module 1 may include a shield case 900 configured to cover a portion of the housing 100 and form a portion of the exterior of the camera module 1 .

[0061] In an example, the camera module 1 may include a first stopper 810 and a second stopper 820 configured to limit movement ranges of the first frame 500 and the second frame 600 , respectively.

[0062] The first stopper 810 may be configured to prevent the first frame 500 from deviating in the +Z direction. Figure 2 , the first stopper 810 may be inserted around the first groove 101 of the housing 100. When the first stopper 810 is inserted into the housing 100, a portion of the first stopper 810 may be disposed on a portion of the first frame 500, so that the first frame 500 may be prevented from deviating from the housing 100 in the +Z direction.

[0063] The second stopper 820 may be configured to prevent the second frame 600 from deviating in the +Z direction. Figure 2 , the second stopper 820 may be inserted around the second groove 501 of the housing 100. When the second stopper 820 is inserted into the housing 100, a portion of the second stopper 820 may be disposed on a portion of the second frame 600, so that the second frame 600 may be prevented from deviating from the housing 100 in the +Z direction.

[0064] Figure 42 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment. Figure 5 It is shown Figure 4 A diagram of a portion of a flexible substrate 400 is shown. Figure 6 It is shown Figure 4 A diagram of a portion of a flexible substrate 400 is shown.

[0065] In an embodiment, the sensor substrate 210 and the main substrate 300 may be connected to each other through the flexible substrate 400. In an example, the main substrate 300 may surround the edge of the sensor substrate 210. For example, referring to Figure 4 , the sensor substrate 210 may have a rectangular plate form, and the main substrate 300 may have a rectangular frame form surrounding the edges 211, 212, 213, and 214 of the sensor substrate 210. The inner edge 310 of the main substrate 300 may surround the edges 211, 212, 213, and 214 of the sensor substrate 210, and the flexible substrate 400 may be disposed between the inner edge 310 of the main substrate 300 and the edges 211, 212, 213, and 214 of the sensor substrate 210.

[0066] In an example, a plurality of flexible substrates 400 may be provided for connecting the sensor substrate 210 to the main substrate 300. A plurality of wirings may need to be provided between the sensor substrate 210 and the main substrate 300, through which electrical signals or power may be transmitted. For example, the image sensor 230 may include a plurality of terminals, and each terminal may require a wiring. The plurality of wirings may be separated and provided on a plurality of flexible substrates 400. Reference Figure 4 The first flexible substrate 410 and the second flexible substrate 420 may connect the sensor substrate 210 to the main substrate 300. An electrical signal or power may be transmitted through electrical wiring included in the first flexible substrate 410 and the second flexible substrate 420.

[0067] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In this example, the configuration in which the flexible substrate 400 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210 may be a configuration in which the flexible substrate 400 is disposed to surround the sensor substrate 210 while being spaced a predetermined distance apart from the edges 211, 212, 213, and 214 of the sensor substrate 210. Therefore, the flexible substrate 400 may be disposed between the edges 211, 212, 213, and 214 of the sensor substrate 210 and the inner edge 310 of the main substrate 300.

[0068] In an exemplary embodiment, the first flexible substrate 410 and the second flexible substrate 420 may be disposed to at least partially overlap each other. The first flexible substrate 410 and the second flexible substrate 420 may extend along the edges 211, 212, 213, and 214 of the sensor substrate 210 in a direction perpendicular to the optical axis O, and may at least partially overlap each other in a direction perpendicular to the optical axis O. In other words, when the flexible substrate 400 is observed in a direction parallel to the optical axis O, a portion of the first flexible substrate 410 may not be visible due to the second flexible substrate 420. Figure 4 In the example shown, the second flexible substrate 420 may be disposed in the +Z direction relative to the first flexible substrate 410 so that a portion of the first flexible substrate 410 is covered by the second flexible substrate 420, but the first flexible substrate 410 and the second flexible substrate 420 are not limited to this configuration. In another example, the first flexible substrate 410 may be disposed in the +Z direction relative to the second flexible substrate 420. In another example, a portion of the first flexible substrate 410 may be disposed on the second flexible substrate 420, and a portion of the second flexible substrate 420 may be disposed on the first flexible substrate 410. Figures 7 to 14 The described embodiments may be the same.

[0069] In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions (e.g., extending outside the sensor substrate 210 on a path around the periphery of the sensor substrate 210), and may be connected to the main substrate 300. In an example, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0070] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0071] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from different portions of the first edge 211. For example, when the sensor substrate 210 is viewed in a direction parallel to the optical axis O, the portion to which the first flexible substrate 410 is connected may be different from the portion to which the second flexible substrate 420 is connected. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, and the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may extend in the -X direction after being led out from the first portion 211c, and the second flexible substrate 420 may extend in the +X direction after being led out from the second portion 211d.

[0072] In an example, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211. Since the first portion 211c is spaced apart from the second portion 211d in the +X direction, the first flexible substrate 410 and the second flexible substrate 420 may partially overlap each other in a region OL1 between the first portion 211c and the second portion 211d.

[0073] In an example, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an exemplary embodiment, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0074] Reference again Figure 3 In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0075] In an exemplary embodiment, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230. The configuration in which the first axis A1 or the second axis A2 may correspond to the diagonal line may indicate that the first axis A1 and the second axis A2 may coincide with or almost coincide with the diagonal line direction.

[0076] The first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211 connecting the first end portion 211 a to the second end portion 211 b .

[0077] The first flexible substrate 410 may be led out from the first portion 211c and may bypass the sensor substrate 210 in a direction toward the first end portion 211a (counterclockwise direction). The second flexible substrate 420 may be led out from the second portion 211d and may bypass the sensor substrate 210 in a direction toward the second end portion 211b (clockwise direction).

[0078] In an embodiment, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may be greater than a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0079] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may be smaller than a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0080] In an exemplary embodiment, the first distance d1 may be greater than the third distance d3, and the second distance d2 may be less than the fourth distance d4.

[0081] When the optical assembly 200 rotates relative to the housing 100, the flexible substrate 400 may interfere with the rotation of the optical assembly 200. Therefore, the flexible substrate 400 may adversely affect the optical image stabilization function. In order to reduce this adverse effect, the flexible substrate 400 may be configured to be elongated. In other words, by increasing the extension length from the main substrate 300 to the sensor substrate 210, the influence of the substrate on the rotation of the optical assembly 200 can be reduced. In an example, the first flexible substrate 410 and the second flexible substrate 420 may be extended until the substrates overlap each other along the edges 211, 212, 213 and 214 of the sensor substrate 210, so that the optical image stabilization function can be improved.

[0082] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0083] In an embodiment, the third portion 311a and the fourth portion 311b may be disposed at the same position when viewed in a direction parallel to the optical axis O. For example, a fifth distance d5 between the third portion 311a and the first axis A1 may coincide with a sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, a seventh distance d7 between the third portion 311a and the second axis A2 may coincide with an eighth distance d8 between the fourth portion 311b and the second axis A2. Thus, the first flexible substrate 410 and the second flexible substrate 420 may overlap each other in a region OL2 extending from the second edge 212 of the sensor substrate 210 to the first inner edge 311 of the main substrate 300.

[0084] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be configured to be symmetrical. In the illustrated embodiment, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Figure 4 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

[0085] refer to Figure 5 and Figure 6, the first flexible substrate 410 may extend a first length L11 from the first portion 211c in the +Y direction, may extend a second length L12 along the first edge 211 in the -X direction, may extend a third length L13 along the third edge 213 in the -Y direction, may extend a fourth length L14 along the second edge 212 in the +X direction, and may extend a fifth length L15 in the -Y direction. The second flexible substrate 420 may extend a sixth length L21 from the second portion 211d in the +Y direction, may extend a seventh length L22 along the first edge 211 in the +X direction, may extend an eighth length L23 along the fourth edge 214 in the -Y direction, may extend a ninth length L24 along the second edge 212 in the -X direction, and may extend a tenth length L25 in the -Y direction. In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed symmetrically with respect to the center line CL, and for example, the first length L11, the second length L12, the third length L13, the fourth length L14, and the fifth length L15 may be respectively consistent with the sixth length L21, the seventh length L22, the eighth length L23, the ninth length L24, and the tenth length L25. As another example, the sum of the first length L11 to the fifth length L15 may be equal to the sum of the sixth length L21 to the tenth length L25.

[0086] In an example, the third distance d3 may be equal to the second distance d2, and the fourth distance d4 may be equal to the first distance d1. In an example, the ninth distance d9 from the center line CL to the first portion 211c may coincide with the tenth distance d10 from the center line CL to the second portion 211d. The ninth distance d9 may be defined by the shortest distance between the center point P1 of the first portion 211c and the center line CL, and the tenth distance d10 may be defined by the shortest distance between the center point P2 of the second portion 211d and the center line CL.

[0087] In an example, a fifth distance d5 between the third portion 311a and the first axis A1 may coincide with an eighth distance d8 between the fourth portion 311b and the second axis A2. In an exemplary embodiment, a seventh distance d7 between the third portion 311a and the second axis A2 may coincide with a sixth distance d6 between the fourth portion 311b and the first axis A1. The distance may be defined by the shortest distance between the center point P3 of the third portion 311a or the center point P4 of the fourth portion 311b and the first axis A1 or the second axis A2.

[0088] In an example, an eleventh distance d11 from the center line CL to the center point P3 of the third portion 311 a may be equal to a twelfth distance d12 from the center line CL to the center point P4 of the fourth portion 311 b .

[0089] In an example, the width W1 of the first flexible substrate 410 may be equal to the width W2 of the second flexible substrate 420 .

[0090] Since the first flexible substrate 410 and the second flexible substrate 420 are symmetrically arranged with respect to the center line CL, the resistance acting on the optical assembly 200 due to the flexible substrate 400 when the optical assembly 200 rotates around the first axis A1 relative to the housing 100 and the resistance acting on the optical assembly 200 due to the flexible substrate 400 when the optical assembly 200 rotates around the second axis A2 can be symmetrical. Therefore, the optical image stabilization function of the camera module 1 can be improved.

[0091] Figure 7 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0092] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed to at least partially overlap each other. The first flexible substrate 410 and the second flexible substrate 420 may extend along the edges 211, 212, 213, and 214 of the sensor substrate 210 in a direction perpendicular to the optical axis O, and may at least partially overlap each other in a direction perpendicular to the optical axis O. In other words, when the flexible substrate 400 is observed in a direction parallel to the optical axis O, a portion of the first flexible substrate 410 may not be visible due to the second flexible substrate 420.

[0093] In an exemplary embodiment, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions (e.g., extend along a path around the sensor substrate 210), and may be connected to the main substrate 300. In an example, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0094] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0095] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from different portions of the first edge 211. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, and the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may be led out from the first portion 211c and may extend in the -X direction, and the second flexible substrate 420 may be led out from the second portion 211d and may extend in the +X direction.

[0096] In an example, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211. Since the first portion 211c is spaced apart from the second portion 211d in the +X direction, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other in a region OL1 between the first portion 211c and the second portion 211d.

[0097] In an example, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an example, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 (opposite to the second edge 212) of the inner edge 310 of the main substrate 300.

[0098] Reference again Figure 3 In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0099] refer to Figure 7In an example, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230.

[0100] The first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211 .

[0101] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b.

[0102] In an example, a first distance d1 between a first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may be greater than a second distance d2 between a second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between a center point P1 of the first portion 211c and the first axis A1 and the shortest distance between a center point P2 of the second portion 211d and the first axis A1, respectively.

[0103] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may be smaller than a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0104] In an example, the first distance d1 may be greater than the third distance d3, and the second distance d2 may be less than the fourth distance d4.

[0105] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to a third portion 311a of the first inner edge 311 opposite to the second edge 212, and the second flexible substrate 420 may be connected to a fourth portion 311b of the first inner edge 311.

[0106] In an exemplary embodiment, when viewed from a direction parallel to the optical axis O, the third portion 311a and the fourth portion 311b may be disposed at different positions. For example, the first flexible substrate 410 may extend beyond the center line CL in the +X direction along the second edge 212, and the second flexible substrate 420 may extend beyond the center line CL in the -X direction along the second edge 212. In this case, the first flexible substrate 410 and the second flexible substrate 420 may overlap each other in the region OL2 between the third portion 311a and the fourth portion 311b. In the example shown, the second flexible substrate 420 may be disposed on the first flexible substrate 410, and in another example, the first flexible substrate 410 may be disposed on the second flexible substrate 420.

[0107] For example, the fifth distance d5 between the third portion 311a and the first axis A1 may be smaller than the sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, the seventh distance d7 between the third portion 311a and the second axis A2 may be greater than the eighth distance d8 between the fourth portion 311b and the second axis A2.

[0108] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed. In the example shown, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Figure 7 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

[0109] Figure 8 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0110] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed to at least partially overlap each other. The first flexible substrate 410 and the second flexible substrate 420 may extend along the edges 211, 212, 213, and 214 of the sensor substrate 210 in a direction perpendicular to the optical axis O, and may at least partially overlap each other in a direction perpendicular to the optical axis O. In other words, when the flexible substrate 400 is observed in a direction parallel to the optical axis O, a portion of the first flexible substrate 410 may not be visible due to the second flexible substrate 420.

[0111] In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions and may be connected to the main substrate 300. In an example, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0112] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0113] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from different portions of the first edge 211. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, and the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may be led out from the first portion 211c and may extend in the -X direction, and the second flexible substrate 420 may be led out from the second portion 211d and may extend in the +X direction.

[0114] In an example, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211. Since the first portion 211c is spaced apart from the second portion 211d in the +X direction, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other in a region OL1 between the first portion 211c and the second portion 211d.

[0115] In an example, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an example, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0116] Reference again Figure 3 In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0117] refer to Figure 8 , in an example, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230.

[0118] The first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211 connecting the first end portion 211 a to the second end portion 211 b .

[0119] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b. In an example, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may be greater than a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0120] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may be smaller than a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0121] In an example, the first distance d1 may be greater than the third distance d3, and the second distance d2 may be less than the fourth distance d4.

[0122] In an exemplary embodiment, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0123] In an example, the third portion 311a and the fourth portion 311b may be disposed at different positions when viewed from a direction parallel to the optical axis O. For example, the first flexible substrate 410 may extend along the second edge 212 in the +X direction until close to the center line CL, and the second flexible substrate 420 may extend along the second edge 212 in the -X direction until close to the center line CL. In this case, the first flexible substrate 410 and the second flexible substrate 420 may not overlap each other in a region between the second edge 212 and the first inner edge 311.

[0124] For example, the fifth distance d5 between the third portion 311a and the first axis A1 may be greater than the sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, the seventh distance d7 between the third portion 311a and the second axis A2 may be less than the eighth distance d8 between the fourth portion 311b and the second axis A2.

[0125] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed. In the exemplary embodiment shown, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Figure 8 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

[0126] Fig. 9 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0127] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed to at least partially overlap each other. The first flexible substrate 410 and the second flexible substrate 420 may extend along the edges 211, 212, 213, and 214 of the sensor substrate 210 in a direction perpendicular to the optical axis O, and may at least partially overlap each other in a direction perpendicular to the optical axis O. In other words, when the flexible substrate 400 is observed in a direction parallel to the optical axis O, a portion of the first flexible substrate 410 may not be visible due to the second flexible substrate 420.

[0128] In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions and may be connected to the main substrate 300. In an example, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0129] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0130] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from the same portion of the first edge 211. That is, when the sensor substrate 210 is viewed in a direction parallel to the optical axis O, the portion to which the first flexible substrate 410 is connected may coincide with the portion to which the second flexible substrate 420 is connected. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction, and the first portion 211c may coincide with the second portion 211d. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may be led out from the first portion 211c and may extend in the -X direction, and the second flexible substrate 420 may be led out from the second portion 211d and may extend in the +X direction.

[0131] In an example, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211. For example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from the same portion of the first edge 211 of the sensor substrate 210 and may overlap each other in a region extending in the +Y direction.

[0132] In an exemplary embodiment, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an exemplary embodiment, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0133] Reference again Figure 3 In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0134] refer to Fig. 9, in an example, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230.

[0135] The first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211 .

[0136] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b. In an example, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may coincide with a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0137] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may coincide with a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0138] In an example, the first distance d1 may coincide with the third distance d3, and the second distance d2 may coincide with the fourth distance d4.

[0139] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0140] In an example, when viewed from a direction parallel to the optical axis O, the third portion 311a and the fourth portion 311b may be disposed at the same position. For example, a fifth distance d5 between the third portion 311a and the first axis A1 may coincide with a sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, a seventh distance d7 between the third portion 311a and the second axis A2 may coincide with an eighth distance d8 between the fourth portion 311b and the second axis A2. Thus, the first flexible substrate 410 and the second flexible substrate 420 may overlap each other in an area OL2 extending from the second edge 212 of the sensor substrate 210 to the first inner edge 311 of the main substrate 300.

[0141] In an exemplary embodiment, the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed. In the example shown, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Fig. 9 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

[0142] Fig.10 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0143] In an exemplary embodiment, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an exemplary embodiment, the first flexible substrate 410 and the second flexible substrate 420 may be disposed to at least partially overlap each other. The first flexible substrate 410 and the second flexible substrate 420 may extend along the edges 211, 212, 213, and 214 of the sensor substrate 210 in a direction perpendicular to the optical axis O, and may at least partially overlap each other in a direction perpendicular to the optical axis O. In other words, when the flexible substrate 400 is observed in a direction parallel to the optical axis O, a portion of the first flexible substrate 410 may not be visible due to the second flexible substrate 420.

[0144] In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions and may be connected to the main substrate 300. In an exemplary embodiment, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0145] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0146] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from the same portion of the first edge 211. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction, and the first portion 211c may overlap with the second portion 211d. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may be led out from the first portion 211c and may extend in the -X direction, and the second flexible substrate 420 may be led out from the second portion 211d and may extend in the +X direction.

[0147] In an example, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211. For example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from the same portion of the first edge 211 of the sensor substrate 210 and may overlap each other in a region extending in the +Y direction.

[0148] In an example, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an exemplary embodiment, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0149] Reference again Figure 3In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0150] refer to Fig.10 In an exemplary embodiment, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230.

[0151] The first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211 .

[0152] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b. In an example, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may coincide with a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0153] In an exemplary embodiment, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may coincide with a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0154] In an example, the first distance d1 may coincide with the third distance d3, and the second distance d2 may coincide with the fourth distance d4.

[0155] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0156] In an example, when viewed from a direction parallel to the optical axis O, the third portion 311a and the fourth portion 311b may be disposed at different positions. For example, the first flexible substrate 410 may extend beyond the center line CL in the +X direction along the second edge 212, and the second flexible substrate 420 may extend beyond the center line CL in the -X direction along the second edge 212. In this case, the first flexible substrate 410 and the second flexible substrate 420 may overlap each other in the region OL2 between the third portion 311a and the fourth portion 311b. In the exemplary embodiment shown, the second flexible substrate 420 may be disposed on the first flexible substrate 410, and in another exemplary embodiment, the first flexible substrate 410 may be disposed on the second flexible substrate 420.

[0157] For example, the fifth distance d5 between the third portion 311a and the first axis A1 may be smaller than the sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, the seventh distance d7 between the third portion 311a and the second axis A2 may be greater than the eighth distance d8 between the fourth portion 311b and the second axis A2.

[0158] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed. In the example shown, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Fig.10 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

[0159] Fig.11 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0160] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed to at least partially overlap each other. The first flexible substrate 410 and the second flexible substrate 420 may extend along the edges 211, 212, 213, and 214 of the sensor substrate 210 in a direction perpendicular to the optical axis O, and may at least partially overlap each other in a direction perpendicular to the optical axis O. In other words, when the flexible substrate 400 is observed in a direction parallel to the optical axis O, a portion of the first flexible substrate 410 may not be visible due to the second flexible substrate 420.

[0161] In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions and may be connected to the main substrate 300. In an example, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0162] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0163] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from the same portion of the first edge 211. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction, and the first portion 211c may overlap with the second portion 211d. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may be led out from the first portion 211c and may extend in the -X direction, and the second flexible substrate 420 may be led out from the second portion 211d and may extend in the +X direction.

[0164] In an exemplary embodiment, the first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211. For example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from the same portion of the first edge 211 of the sensor substrate 210 and may overlap each other in a region extending in the +Y direction.

[0165] In an example, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an example, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0166] Reference again Figure 3 In an exemplary embodiment, the optical assembly 200 is rotatable relative to the housing 100 about a first axis A1 and a second axis A2 that are perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 is rotatable relative to the main substrate 300 about the first axis A1 and the second axis A2.

[0167] refer to Fig.11 In an example, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. The first flexible substrate 410 and the second flexible substrate 420 may at least partially overlap each other along the first edge 211.

[0168] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b. In an example, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may coincide with a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0169] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may coincide with a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0170] In an example, the first distance d1 may coincide with the third distance d3, and the second distance d2 may coincide with the fourth distance d4.

[0171] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0172] In an exemplary embodiment, the third portion 311a and the fourth portion 311b may be disposed at different positions when viewed from a direction parallel to the optical axis O. For example, the first flexible substrate 410 may extend along the second edge 212 in the +X direction until close to the center line CL, and the second flexible substrate 420 may extend along the second edge 212 in the -X direction until close to the center line CL. In this case, the first flexible substrate 410 and the second flexible substrate 420 may not overlap each other in a region between the second edge 212 and the first inner edge 311.

[0173] For example, the fifth distance d5 between the third portion 311a and the first axis A1 may be greater than the sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, the seventh distance d7 between the third portion 311a and the second axis A2 may be less than the eighth distance d8 between the fourth portion 311b and the second axis A2.

[0174] Fig.12 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0175] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions and may be connected to the main substrate 300. In an exemplary embodiment, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0176] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0177] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from different portions of the first edge 211. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, and the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may extend in the -X direction after being led out from the first portion 211c, and the second flexible substrate 420 may extend in the +X direction after being led out from the second portion 211d.

[0178] In an example, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an exemplary embodiment, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0179] Reference again Figure 3 In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0180] refer to Fig.12 , in an example, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230.

[0181] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b. In an example, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may be smaller than a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0182] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may be greater than a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0183] In an example, the first distance d1 may be smaller than the third distance d3, and the second distance d2 may be greater than the fourth distance d4.

[0184] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0185] In an example, when viewed from a direction parallel to the optical axis O, the third portion 311a and the fourth portion 311b may be disposed at the same position. For example, a fifth distance d5 between the third portion 311a and the first axis A1 may coincide with a sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, a seventh distance d7 between the third portion 311a and the second axis A2 may coincide with an eighth distance d8 between the fourth portion 311b and the second axis A2. Thus, the first flexible substrate 410 and the second flexible substrate 420 may overlap each other in an area OL2 extending from the second edge 212 of the sensor substrate 210 to the first inner edge 311 of the main substrate 300.

[0186] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed. In the example shown, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Fig.12 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

[0187] Fig.13 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0188] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions and may be connected to the main substrate 300. In an embodiment, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0189] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0190] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from different portions of the first edge 211. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, and the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may be led out from the first portion 211c and may extend in the -X direction, and the second flexible substrate 420 may be led out from the second portion 211d and may extend in the +X direction.

[0191] In an exemplary embodiment, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an exemplary embodiment, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0192] Reference again Figure 3In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0193] refer to Fig.13 , in an example, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230.

[0194] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b. In an example, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may be smaller than a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0195] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may be greater than a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0196] In an example, the first distance d1 may be smaller than the third distance d3, and the second distance d2 may be greater than the fourth distance d4.

[0197] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0198] In an example, when viewed from a direction parallel to the optical axis O, the third portion 311a and the fourth portion 311b may be disposed at different positions. For example, the first flexible substrate 410 may extend beyond the center line CL in the +X direction along the second edge 212, and the second flexible substrate 420 may extend beyond the center line CL in the -X direction along the second edge 212. In this case, the first flexible substrate 410 and the second flexible substrate 420 may overlap each other in the region OL2 between the third portion 311a and the fourth portion 311b. In the example shown, the second flexible substrate 420 may be disposed on the first flexible substrate 410, and in another example, the first flexible substrate 410 may be disposed on the second flexible substrate 420.

[0199] For example, the fifth distance d5 between the third portion 311a and the first axis A1 may be smaller than the sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, the seventh distance d7 between the third portion 311a and the second axis A2 may be greater than the eighth distance d8 between the fourth portion 311b and the second axis A2.

[0200] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed. In the exemplary embodiment shown, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Fig.13 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

[0201] Fig.14 2 is a diagram showing a connection structure between the sensor substrate 210 and the main substrate 300 according to an embodiment.

[0202] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be disposed along the edges 211, 212, 213, and 214 of the sensor substrate 210. In an example, the first flexible substrate 410 and the second flexible substrate 420 may bypass the sensor substrate 210 in opposite directions and may be connected to the main substrate 300. In an exemplary embodiment, the first flexible substrate 410 may bypass the sensor substrate 210 in a counterclockwise direction relative to the optical axis O, and the second flexible substrate 420 may bypass the sensor substrate 210 in a clockwise direction relative to the optical axis O.

[0203] For example, the first flexible substrate 410 may extend in the −X direction along a portion of the first edge 211, may extend in the −Y direction along the third edge 213, may extend in the +X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300. The second flexible substrate 420 may extend in the +X direction along a portion of the first edge 211, may extend in the −Y direction along the fourth edge 214, may extend in the −X direction along a portion of the second edge 212, and may be connected to the inner edge 310 of the main substrate 300.

[0204] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be led out from different portions of the first edge 211. For example, the first flexible substrate 410 may extend from the first portion 211c of the first edge 211 in the +Y direction, and the second flexible substrate 420 may extend from the second portion 211d of the first edge 211 in the +Y direction. The first flexible substrate 410 and the second flexible substrate 420 may extend in opposite directions along the first edge 211. For example, the first flexible substrate 410 may be led out from the first portion 211c and may extend in the -X direction, and the second flexible substrate 420 may be led out from the second portion 211d and may extend in the +X direction.

[0205] In an exemplary embodiment, the flexible substrate 400 may bypass the sensor substrate 210 and may be connected to the main substrate 300. In an exemplary embodiment, the flexible substrate 400 may be led out from the first edge 211 of the sensor substrate 210 and may extend to the second edge 212 opposite to the first edge 211. The portion of the flexible substrate 400 extending to the second edge 212 may be connected to a portion of the first inner edge 311 of the inner edge 310 of the main substrate 300 opposite to the second edge 212.

[0206] Reference again Figure 3 In the example, the optical assembly 200 can rotate relative to the housing 100 around the first axis A1 and the second axis A2 perpendicular to the optical axis O. Since the sensor substrate 210 is fastened to the optical assembly 200 and the main substrate 300 is fastened to the housing 100, the sensor substrate 210 can rotate relative to the main substrate 300 around the first axis A1 and the second axis A2.

[0207] In an example, the first edge 211 may extend from the first end 211a to the second end 211b in the +X direction, and the second edge 212 may extend from the third end 212a to the fourth end 212b in the +X direction while being opposite to the first edge 211. In this case, the first axis A1 may correspond to a diagonal line from the first end 211a to the fourth end 212b, and the second axis A2 may correspond to a diagonal line from the second end 211b to the third end 212a. Alternatively, the first axis A1 may correspond to a first diagonal line 231 of the image sensor 230, and the second axis A2 may correspond to a second diagonal line 232 of the image sensor 230.

[0208] After being led out from the first portion 211c, the first flexible substrate 410 may bypass the sensor substrate 210 in a direction (counterclockwise) toward the first end portion 211a. After being led out from the second portion 211d, the second flexible substrate 420 may bypass the sensor substrate 210 in a direction (clockwise) toward the second end portion 211b. In an example, a first distance d1 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the first axis A1 may be smaller than a second distance d2 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the first axis A1. The first distance d1 and the second distance d2 may be defined by the shortest distance between the center point P1 of the first portion 211c and the first axis A1 and the shortest distance between the center point P2 of the second portion 211d and the first axis A1, respectively.

[0209] In an example, a third distance d3 between the first portion 211c where the first flexible substrate 410 is connected to the sensor substrate 210 and the second axis A2 may be greater than a fourth distance d4 between the second portion 211d where the second flexible substrate 420 is connected to the sensor substrate 210 and the second axis A2. The third distance d3 and the fourth distance d4 may be defined by the shortest distance between the center point P1 of the first portion 211c and the second axis A2 and the shortest distance between the center point P2 of the second portion 211d and the second axis A2, respectively.

[0210] In an example, the first distance d1 may be smaller than the third distance d3, and the second distance d2 may be greater than the fourth distance d4.

[0211] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be connected to a portion of the inner edge 310 of the main substrate 300. The first flexible substrate 410 may be connected to the third portion 311a of the first inner edge 311, and the second flexible substrate 420 may be connected to the fourth portion 311b of the first inner edge 311.

[0212] In an exemplary embodiment, the third portion 311a and the fourth portion 311b may be disposed at different positions when viewed from a direction parallel to the optical axis O. For example, the first flexible substrate 410 may extend along the second edge 212 in the +X direction until close to the center line CL, and the second flexible substrate 420 may extend along the second edge 212 in the -X direction until close to the center line CL. In this case, the first flexible substrate 410 and the second flexible substrate 420 may not overlap each other in a region between the second edge 212 and the first inner edge 311.

[0213] For example, the fifth distance d5 between the third portion 311a and the first axis A1 may be greater than the sixth distance d6 between the fourth portion 311b and the first axis A1. Alternatively, the seventh distance d7 between the third portion 311a and the second axis A2 may be less than the eighth distance d8 between the fourth portion 311b and the second axis A2.

[0214] In an example, the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed. In the exemplary embodiment shown, the center line CL may separate the first axis A1 and the second axis A2 and may be parallel to the Y axis. Fig.14 , the first flexible substrate 410 and the second flexible substrate 420 may be symmetrically disposed with respect to a center line CL parallel to the Y-axis.

The camera module according to the embodiments disclosed herein can rotate a relatively large angle, so that a tracking function can be implemented when shooting a video.

[0216] Furthermore, when the shake is corrected by rotating the image sensor, the electrical wiring for transmitting the signal of the image sensor may be configured not to interfere with the rotation of the image sensor.
