The lens assembly (210) may collect light emitted from a subject that is a target of image capturing. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera module (180) may include a plurality of lens assemblies (210). In this case, the camera module (180) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies (210) may have the same lens properties (e.g., angle of view, focal length, autofocus, f-number, or optical zoom), or at least one lens assembly may have one or more lens properties that are different from the lens properties of the other lens assemblies. A lens assembly (210) may include, for example, a wide-angle lens or a telephoto lens.

[0071] The flash (220) can emit light used to enhance light emitted or reflected from a subject. According to one embodiment, the flash (220) can include one or more light-emitting diodes (e.g., red-green-blue (RGB) LED, white LED, infrared LED, or ultraviolet LED), or a xenon lamp. The image sensor (230) can acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through the lens assembly (210) into an electrical signal. According to one embodiment, the image sensor (230) can include one image sensor selected from among image sensors having different properties, such as, for example, an RGB sensor, a black and white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same property, or a plurality of image sensors having different properties. Each image sensor included in the image sensor (230) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0072] The image stabilizer (240) can move at least one lens or image sensor (230) included in the lens assembly (210) in a specific direction or control the operating characteristics of the image sensor (230) (e.g., adjusting the read-out timing, etc.) in response to the movement of the camera module (180) or the electronic device (101) including the same. This allows compensating for at least some of the negative effects of the movement on the captured image. In one embodiment, the image stabilizer (240) can detect such movement of the camera module (180) or the electronic device (101) by using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module (180). In one embodiment, the image stabilizer (240) can be implemented as, for example, an optical image stabilizer. The memory (250) can temporarily store at least a portion of the image acquired through the image sensor (230) for the next image processing task. For example, when image acquisition is delayed due to the shutter, or when multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in the memory (250), and a corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Thereafter, when a specified condition is satisfied (e.g., a user input or a system command), at least a portion of the original image stored in the memory (250) can be acquired and processed, for example, by the image signal processor (260). According to one embodiment, the memory (250) can be configured as at least a portion of the memory (130) or as a separate memory that operates independently therefrom.

[0073] The image signal processor (260) can perform one or more image processing operations on an image acquired through an image sensor (230) or an image stored in a memory (250). The one or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature point extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor (260) may perform control (e.g., exposure time control, read-out timing control, etc.) on at least one of the components included in the camera module (180) (e.g., image sensor (230)). An image processed by the image signal processor (260) may be stored back in the memory (250) for further processing or provided to an external component of the camera module (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108)). According to one embodiment, the image signal processor (260) may include at least one of the processors (120). It may be configured as a separate processor that is configured as a part of the processor (120) or operates independently of the processor (120). If the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (160) as is or after undergoing additional image processing by the processor (120).

[0074] According to one embodiment, the electronic device (101) may include a plurality of camera modules (180), each having different properties or functions. In this case, for example, at least one of the plurality of camera modules (180) may be a wide-angle camera, and at least another may be a telephoto camera. Similarly, at least one of the plurality of camera modules (180) may be a front camera, and at least another may be a rear camera.

[0131] The first guide (G1) may include a first groove (G11). The first groove (G11) may be disposed on the first AF carrier side wall (441B) between the first AF carrier corner area (C21) and the second AF carrier corner area (C22).

The first groove (G11) may extend along the first AF carrier side wall (441B) in the height direction (e.g., the Z-axis direction) of the first AF carrier side wall (441B).

[0132] The first guide (G1) may include a second groove (G12). The second groove (G12) may be disposed in the first housing side wall (421B) between the first housing corner region (C11) and the second housing corner region (C12).

[0133] The first groove (G11) and the second groove (G12) may each generally include a V-shaped groove. The first groove (G11) and the second groove (G12) may ensure linear movement of the AF carrier (441) in a direction along the optical axis (A) (e.g., in the Z-axis direction) and may reduce or prevent shaking (e.g., tilt) of the AF carrier (441).

[0134] The first guide (G1) may include a plurality of first balls (B11, B12, B13). The plurality of first balls (B11, B12, B13) may include a plurality of first main balls (B11, B12) and a first sub ball (B13) disposed between the plurality of first main balls (B11, B12).

The size (e.g., diameter) of each of the first main balls (B11, B12) may be larger than the size (e.g., diameter) of the first sub ball (B13). From the bottom portion (421A), one first main ball (B11), one first sub ball (B13) and one other first main ball (B12) may be arranged in a direction along the optical axis (A) (e.g., in the Z-axis direction). In an embodiment not shown, the first guide (G1) may not include the first sub ball (B13).

[0135] The first groove (G11) and the second groove (G12) may be positioned within a length range of L / 4 on a first side (e.g., +Y-direction side) and a length range of L / 4 on a second side (e.g., -Y-direction side) based on a center area of ​​the width of the camera module (400). The width of the camera module (400) may be defined by the length between the first housing corner area (C11) and the second housing corner area (C12). In one embodiment, the first groove (G11) and the second groove (G12) may be offset to one side (e.g., -Y-direction side) from a center area of ​​the width of the camera module (400) that does not interfere with the lens housing (412).

[0136] The cover frame (422) may include a first protrusion (422D) that protrudes toward the ball receiving space defined by the first groove (G11) and the second groove (G12). The first protrusion (422D) may be formed by pressing at least a portion of the top portion (422A) in a direction (e.g., -Z direction) from the top portion (422A) toward the bottom portion (421A).

[0138] The second guide (G2) may include a third groove (G21). The third groove (G21) may be disposed in the first AF carrier corner region (C21). The third groove (G21) may extend in the height direction (e.g., in the Z-axis direction) of the first AF carrier side wall (441B) along the first AF carrier side wall (441B). The third groove (G21) may extend from a step (ST) that is located in the first AF carrier corner region (C21) of the AF carrier (441) and extends from the AF carrier base (441A) in the height direction (e.g., in the Z-axis direction) of the first AF carrier side wall (441B).

[0139] The second guide (G2) may include a fourth groove (G22). The fourth groove (G22) may be arranged in the first housing corner region (C11). The fourth groove (G22) may extend from the bottom portion (421A) along the height (e.g., the Z-axis dimension) of the first housing side wall (421B). At least a portion of the fourth groove (G22) may face the third groove (G21). At least a portion of the fourth groove (G22) may face the step (ST).

[0140] One of the third groove (G21) and the fourth groove (G22) may comprise a generally U-shaped groove, and the other of the third groove (G21) and the fourth groove (G22) may comprise a generally V-shaped groove. The third groove (G21) and the fourth groove (G22) may reduce or prevent rotational movement of the AF carrier (441) with respect to the optical axis (A).

[0141] The second guide (G2) may include at least one second ball (B21, B22). For example, the second guide (G2) may include at least one second main ball (B21) and a second sub-ball (B22) disposed on at least one second main ball (B21). At least one of the second main ball (B21) and the second sub-ball (B22) may be in rolling contact with the third groove (G21) and the fourth groove (G22). The size (e.g., diameter) of the second main ball (B21) may be larger than the size (e.g., diameter) of the second sub-ball (B22). In an embodiment not shown, the second guide (G2) may not include the second sub-ball (B22).

[0142] The third groove (G21) and the fourth groove (G22) may be positioned outside the ±L / 4 length range based on the center area of ​​the width of the camera module (400).

[0143] The cover frame (422) may include a second protrusion (422E) that protrudes toward the ball receiving space defined by the third groove (G21) and the fourth groove (G22). The second protrusion (422E) may be formed by pressing at least a portion of the top portion (422A) in a direction (e.g., -Z direction) from the top portion (422A) toward the bottom portion (421A). The protrusion length of the second protrusion (422E) may define a rolling distance of at least one second ball (B21, B22).

[0144] The center of attraction (SC) on which the resultant force of the attraction between the first AF magnet (442A) and the yoke (446) and the attraction between the second AF magnet (442B) and the yoke (446) acts may be located within a virtual support surface (P) connecting a plurality of first main balls (B11, B12) and at least one second main ball (B21). The center of attraction (SC) may overlap the first AF magnet (442A) when viewed in the direction between the first AF magnet (442A) and the yoke (446) (e.g., in the X-axis direction).

[0145] The attraction force between the first AF magnet (442A) and the yoke (446) may be greater than the attraction force between the second AF magnet (442B) and the yoke (446). This may reduce or prevent rotational movement of the AF carrier (441) relative to the first guide (G1) and reduce or prevent detachment of at least one first main ball (B11, B12) from the second guide (G2). The above condition can be satisfied, for example, by the case where the height (e.g., dimension in the Z-axis direction) of the first AF magnet (442A) and the height (e.g., dimension in the Z-axis direction) of the second AF magnet (442B) are substantially the same, the thickness (e.g., dimension in the X-axis direction) of the first AF magnet (442A) and the thickness (e.g., dimension in the X-axis direction) of the second AF magnet (442B) are substantially the same, the first AF magnet (442A) and the second AF magnet (442B) include magnetic materials of the same grade, and the length (e.g., dimension in the Y-axis direction) of the first AF magnet (442A) is greater than the length (e.g., dimension in the Y-axis direction) of the second AF magnet (442B).

[0146] The structure of arranging the first groove (G11) and the second groove (G12) within a length range of ±L / 4 based on the center area of ​​the width of the camera module (400) can increase the tilt safety factor of the camera module (400) by reducing the length of one edge connecting the first main ball (B11) and the second main ball (B21) among the edges constituting the virtual support surface (P) and the length of the edge connecting the other first main ball (B12) and the second main ball (B21), and reducing the shortest distance between the edges constituting the virtual support surface (P) and the center of attraction (SC). The increased tilt safety factor can reduce the distance between the first main balls (B11, B12), and reduce the size of the camera module (400).

[0147] The camera module (400) may include an OIS guide (G4) configured to guide the OIS carrier (451) relative to the AF carrier (441) in a direction substantially orthogonal to the optical axis (A) (e.g., in the XY plane direction). The OIS guide (G4) may include a plurality of first curved grooves (G41) arranged on a surface (e.g., in the +Z direction) of the AF carrier base (441A), a plurality of second curved grooves (G42) (not shown in the drawing) arranged on a surface (e.g., in the -Z direction) of the OIS carrier base and facing the plurality of first curved grooves (G41), and a plurality of OIS balls (B4) that contact the plurality of first curved grooves (G41) and the plurality of second curved grooves (G42), respectively. The plurality of first curved grooves (G41) and the plurality of second curved grooves (G42) may generally comprise a hemispherical shape.

[0148] The camera module (400) may include a stopper (460), which may be referred to as a “Z-stopper.” The stopper (460) may be configured to reduce or prevent the OIS carrier (451) from being dislodged from the AF carrier (441). When the OIS carrier (451) is dislodged a certain distance along the optical axis (A), the stopper (460) may reduce or prevent the plurality of first balls (B11, B12, B13) and at least one second ball (B21, B22) from being dislodged from their positions. The stopper (460) may be disposed between the OIS carrier (451) and the cover frame (422). The stopper (460) may be coupled to the AF carrier (441).

[0149] The camera module (400) may include a flexible printed circuit board (480). The flexible printed circuit board (480) may include a first substrate area (480A) (e.g., a +X-direction substrate area) disposed on a first housing side wall (421B), a second substrate area (480B) (e.g., a +Y-direction substrate area) connected to the first substrate area (480A) and disposed on a third housing side wall (421D), and a third substrate area (480C) (e.g., a -X-direction substrate area) connected to the second substrate area (480B) and opposite the first substrate area (480A) and disposed on a second housing side wall (421C). The first AF coil (443A), the second AF coil (443B), the AF drive (444), and the metal piece (445) may be disposed on an inner surface (e.g., a -X direction surface) of the first substrate area (480A) and may be electrically connected to the first substrate area (480A). The metal piece (445) may be fixed to the first substrate area (480A). The yoke (446) may be disposed on an outer surface (e.g., a +X direction surface) of the first substrate area (480A). A plurality of first OIS coils (453A) and the first OIS drive (454A) may be disposed on an inner surface (e.g., a -Y direction surface) of the second substrate area (480B) and may be electrically connected to the second substrate area (480B). A plurality of second OIS coils (453B) and a plurality of second OIS drives (454B) may be arranged on an inner surface (e.g., a +X direction surface) of the third substrate area (480C) and electrically connected to the third substrate area (480C).
