Description

Camera module and electronic device including same

[0001] Embodiments disclosed in this document relate to a camera module and an electronic device including the same.

[0002] As digital camera technology developed, electronic devices equipped with compact, lightweight camera modules became commercially available. With camera modules integrated into electronic devices we typically carry with us (e.g., mobile terminals), users could conveniently utilize a variety of features, including not only taking photos and videos, but also video calling and augmented reality.

[0003] Recently, electronic devices containing multiple cameras have become widespread. Miniaturized electronic devices containing multiple cameras may include folded optics cameras. Folded optics cameras can refract light regardless of the direction from which external light is incident by arranging an optical element, such as an optical refractive element (e.g., a prism).

[0004] For a camera module to capture images, the lens must be focused so that the image is accurately captured on the image sensor within the camera module. Furthermore, as electronic devices become smaller, the image quality can deteriorate due to the user's movements while holding the device.

[0005] Autofocus (AF) is the function of an optical system that automatically adjusts focus on a subject. Electronic devices can move the lens or image sensor to focus on the subject.

[0006] Optical image stabilization (OIS) technology can be applied to improve the image quality of captured images. Electronic devices can detect the movement of the electronic device using a motion sensor embedded in the device. The electronic device can then drive the lens or image sensor to move in response to the movement of the electronic device, thereby obtaining a stabilized image.

[0007] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

The first driving unit may include a first carrier that transports at least a portion of the second driving unit that accommodates the image sensor in the first direction, and at least one first sphere that is disposed between the first carrier and the housing and that allows the first carrier to move in the first direction with respect to the housing.

[0035] Figure 1 is a perspective view of a camera module (100) according to one embodiment.

[0036] A camera module (100) according to an embodiment may include a lens assembly (110), an optical refractive member (120), an image sensor (not shown), a housing (130), a first driving unit (not shown) for driving auto focus (AF) of the camera module (100), and a second driving unit (not shown) for driving optical image stabilization (OIS) of the camera module (100). However, the components of the camera module (100) are not limited thereto. For example, the camera module (100) may omit at least one of the above-described components, or may further include at least one component. For example, the camera module (100) may further include a carrier (140) for accommodating the optical refractive member (120), and a cover (150) for covering at least a portion of the housing (130).

[0037] According to one embodiment, the housing (130) and / or the cover (150) may form the exterior of the camera module (100). For example, the housing (130) may provide a framework for supporting other components. The shape of the housing (130) and / or the cover (150) may be modified depending on the shape of the camera module (100) or the components included in the camera module (100). For example, the housing (130) and / or the cover (150) may be a box-shaped housing.

[0038] According to one embodiment, the cover (150) may cover at least a portion of the housing (130). For example, the cover (150) may cover at least a portion of a side surface of the housing (130) and an upper portion of the housing (130). However, the present invention is not limited thereto. For example, the housing (130) may be a single member with the cover (150). The cover (150) may form a space with the housing (130). In the space formed between the housing (130) and the cover (150), at least one of an optical refractive member (120), a carrier (140) in which the optical refractive member (120) is disposed, an image sensor, a first driving unit for AF driving of the camera module (100) or a second driving unit for OIS driving of the camera module (100) may be disposed.

[0039] According to one embodiment, a lens assembly (110) including at least one lens may be disposed on an optical refractive member (120). For example, the lens assembly (110) may be disposed on an upper surface of the optical refractive member (120) facing a first direction (e.g., a z-axis direction or a -z-axis direction).

[0040] Fig. 2 is a cutaway view of the camera module (100) of Fig. 1.

[0041] The camera module (100) of FIG. 2 may be referred to as the camera module (100) of FIG. 1. The same terms and / or the same reference numerals are used for components that are identical or substantially identical to those described above.

[0042] Referring to FIG. 2, a camera module (100) according to an embodiment may include a lens assembly (110), an optical refractive member (120), an image sensor (160), a housing (130), a first driving unit (e.g., a first carrier (210)) for AF driving of the camera module (100), and a second driving unit (e.g., a second carrier (310)) for OIS driving of the camera module (100). However, the components of the camera module (100) are not limited thereto. For example, the camera module (100) may omit at least one of the above-described components, or may further include at least one component. For example, referring to FIG. 2, the camera module (100) may further include a carrier (140) for accommodating the optical refractive member (120), and a cover (150) for covering at least a portion of the housing (130).

[0043] According to one embodiment, the lens assembly (110) may include at least one lens (111) arranged such that an image of a subject is formed on the image sensor (160). The camera module (100) may receive light through the lens assembly (110). For example, the light may enter the interior of the camera module (100) through at least a portion of the at least one lens (111). In one example, the light may enter the interior of the camera module (100) in a first direction (e.g., the -z-axis direction).

[0044] According to one embodiment, at least a portion of the lens assembly (110) may be exposed to the exterior of the camera module (100). For example, at least a portion of the lens assembly (110) may be positioned to protrude from an upper surface (e.g., a surface facing the +z direction) of the housing (130) or cover (150).

[0045] According to one embodiment, the optical refractive member (120) can change the path of light entering the interior of the camera module (100) through the lens assembly (110). For example, the optical refractive member (120) can be arranged to refract the path of light passing through at least a portion of at least one lens (111). Light entering the interior of the camera module (100) can be refracted at least once by the optical refractive member (120).

[0046] According to one embodiment, the optical refractive member (120) may include at least one of a prism or a reflective member.

[0047] According to one embodiment, the optical refractive member (120) may be arranged to refract the path along which light travels so that light passing through the optical refractive member (120) is incident on the image sensor (160). The light refracted through the optical refractive member (120) may be introduced into the image sensor (160). For example, in one example, the light refracted through the optical refractive member (120) may be introduced into the image sensor (160) in a first direction (e.g., the -z-axis direction).

[0048] According to one embodiment, at least one of the lens assembly (110) or the optical refractive member (120) may be fixed to the housing (130). For example, the optical refractive member (120) may be fixed to a carrier (140) fixed to the housing (130). For example, the optical refractive member (120) may be fixed to the housing (130) using a bracket. By fixing the optical refractive member (120) to the housing (130), the optical refractive member (120) may not be driven. By not driving the optical refractive member (120), distortion of the image due to driving of the optical refractive member (120) can be prevented.

[0049] According to one embodiment, the image sensor (160) may be positioned below the optical refractive member (120) (e.g., below in the -z direction). For example, the image sensor (160) may be positioned below the carrier (140) that accommodates the optical refractive member (120).

[0050] According to one embodiment, the image sensor (160) can move in an internal space formed by the housing (130) with respect to the housing (130) (or, a space between the housing (130) and the cover (150). For example, the image sensor (160) can move in a first direction (e.g., in the z-axis direction or the -z-axis direction) with respect to the housing (130) by a first driving unit (e.g., the first carrier (210)) for driving the AF of the camera module (100). For example, the image sensor (160) can move in at least one of a second direction (e.g., in the x-axis direction or the -x-axis direction) or a third direction (e.g., in the y-axis direction or the -y-axis direction) with respect to the housing (130) by a second driving unit (e.g., the second carrier (310)) for driving the OIS of the camera module (100). However, the present invention is not limited thereto. For example, the image sensor (160) may be rotated (rolled) or tilted (tilted) around the optical axis direction (e.g., the z-axis direction or the -z-axis direction) by a second driving unit (e.g., the second carrier (310)) for driving the OIS of the camera module (100). According to one embodiment, the image sensor (160) may be accommodated in the second driving unit.

[0051] According to one embodiment, the camera module (100) may include a printed circuit board (170) accommodated inside the housing (130). The printed circuit board (170) may include a flexible circuit board. In one example, the printed circuit board (170) may overlap at least a portion of the optical refractive member (120). For example, when the camera module (100) is viewed from above (e.g., when viewed in the -z-axis direction), at least a portion of the printed circuit board (170) may overlap at least a portion of the optical refractive member (120). In one example, the printed circuit board (170) may be arranged to surround at least a portion of the optical refractive member (120). For example, the printed circuit board (170) may be arranged to surround at least one of a side surface (e.g., a surface facing the second direction or the third direction), a back surface (e.g., a surface facing the -z-axis direction), or an inclined surface of the optical refractive member (120).

[0052] According to one embodiment, the image sensor (160) may be disposed on a printed circuit board (170). For example, the image sensor (160) may be fixed to the printed circuit board (170). By disposing the image sensor (160) on the printed circuit board (170), the image sensor (160) may move in the internal space formed by the housing (130) with respect to the housing (130) together with the printed circuit board (170).

[0053] According to one embodiment, the optical refractive member (120) may be positioned to be spaced apart from the image sensor (160) by a predetermined distance. For example, the optical refractive member (120) may be positioned to be spaced apart from the image sensor (160) in a first direction (e.g., in the z-axis direction or the -z-axis direction). For example, the optical refractive member (120) may be spaced apart from the optical refractive member (120) by a first distance when the image sensor (160) moves in the z-axis direction from the reference position. The optical refractive member (120) may be spaced apart from the optical refractive member (120) by a second distance greater than the first distance when the image sensor (160) moves in the -z-axis direction from the reference position.

[0054] According to one embodiment, when the camera module is a 5x module, the shooting distance is about 50 cm to 1 m, and the subject is 80 cm, the AF stroke value of the first driving unit for AF driving may be about 0.6 mm, but is not limited thereto.

[0055] According to one embodiment, the first carrier (140) can transport the image sensor (160) in a first direction (e.g., the z-axis direction or the -z-axis direction) by a first distance based on at least one opening (141). When the image sensor (160) is transported by the first carrier (140) in the first direction by the first distance, the image sensor (160) can be arranged to be spaced apart from the at least one opening (141) by a predetermined distance. For example, when the image sensor (160) and the at least one opening (141) are spaced apart by a second distance, the second distance may be greater than the first distance. For example, when the second distance by which the image sensor (160) and the at least one opening (141) are spaced apart has a minimum value, the second distance may be greater than the first distance. For example, the second distance may be the sum of the predetermined distance and the first distance. However, the present invention is not limited thereto.

[0056] In one example, the second distance may be about 0.4 mm or more, but is not limited thereto.

[0057] According to one embodiment, a carrier (140) that accommodates an optical refractive element (120) may include at least one opening (141) positioned between the optical refractive element (120) and an image sensor (160). The at least one opening (141) may be open in a direction toward the image sensor (160) (e.g., in the -z-axis direction).

[0058] According to one embodiment, the optical refractive member (120) may be arranged to refract the path along which light travels so that light passing through the optical refractive member (120) enters the image sensor (160) through at least one opening (141). Light refracted through the optical refractive member (120) may pass through at least one opening (141) and enter the image sensor (160).

[0059] According to one embodiment, at least one opening (141) may be arranged to be spaced apart from the optical refractive member (120) by a predetermined distance. For example, at least one opening (141) may be spaced apart from the optical refractive member (120) in a first direction (e.g., in the z-axis direction). The carrier (140) may include a recess for arranging at least one opening (141) to be spaced apart from the optical refractive member (120) by a predetermined distance. For example, a space may be formed between the optical refractive member (120) and at least one opening (141).

[0060] According to one embodiment, at least one opening (141) may be positioned to be spaced apart from the image sensor (160) by a predetermined distance. For example, at least one opening (141) may be spaced apart from the image sensor (160) in a first direction (e.g., in the -z-axis direction).

[0061] According to one embodiment, the camera module (100) may include at least one filter (142) disposed between the optical refractive member (120) and the image sensor (160). For example, the at least one filter (142) may be disposed in at least one opening (141), but the present invention is not limited thereto. For example, the at least one filter (142) may be disposed in the image sensor (160). For example, the at least one filter (142) may move together with the image sensor (160). The at least one filter (142) may be disposed to be spaced apart from the optical refractive member (120). The at least one filter (142) may be disposed to be spaced apart from the image sensor (160). In one example, the at least one filter (142) may include, but is not limited to, an infrared filter.

[0062] FIG. 3 is a perspective view illustrating a driving unit for AF driving of a camera module according to one embodiment.

[0063] The camera module of FIG. 3 may be referred to as the camera module (100) of FIGS. 1 and 2. The same terms and / or the same reference numerals are used for components that are identical or substantially identical to those described above, and any duplicate descriptions are omitted.

[0064] According to one embodiment, the camera module may include a first driving unit (200) for an auto-focus function. The first driving unit (200) may move an image sensor (e.g., the image sensor (160) of FIG. 2) in a first direction (e.g., the z-axis direction or the -z-axis direction). The first driving unit (200) according to one embodiment may include an AF actuator configured to move the image sensor for the auto-focus function. For example, the first driving unit (200) may move the image sensor in a first direction (e.g., the z-axis direction or the -z-axis direction) in which a distance between the optical refractive member and the image sensor is changed for the auto-focus function.

[0065] According to one embodiment, the first driving unit (200) may include a first carrier (210) and at least one first sphere (220). However, the components of the first driving unit (200) are not limited thereto. For example, the first driving unit (200) may omit at least one of the above-described components, or may further include at least one other component. For example, the first driving unit (200) may further include at least one of a first magnet (221), a first coil (222), at least one second sphere (230), at least one first guide portion (240), or at least one second guide portion (250).

[0066] According to one embodiment, the first carrier (210) can transport at least a portion of the second driving unit that accommodates the image sensor (e.g., the image sensor (160) of FIG. 2) in a first direction (e.g., the z-axis direction or the −z-axis direction). For example, the first carrier (210) can transport the second carrier (310) that accommodates the image sensor in the first direction. In one example, the first carrier (210) can surround at least a portion of the second carrier (310). For example, the first carrier (210) can surround at least a portion of a side surface of the second carrier (310).

[0067] According to one embodiment, at least one first sphere (220) may be positioned between a first carrier (210) and a housing (e.g., housing (130) of FIG. 2). The at least one first sphere (220) may be positioned such that the first carrier (210) moves in the first direction relative to the housing. For example, the at least one first sphere (220) may be positioned side by side along the first direction.

[0068] According to one embodiment, the first driving unit (200) may further include at least one second sphere (230). The at least one second sphere (230) may be disposed between the first carrier (210) and the housing. The at least one second sphere (230) may be disposed such that the first carrier (210) moves in the first direction with respect to the housing. For example, the at least one second sphere (230) may be disposed side by side along the first direction. In one example, the at least one second sphere (230) may be disposed side by side with the at least one first sphere (220).

[0069] According to one embodiment, at least one second sphere (230) may be positioned so as to be spaced apart from at least one first sphere (220) by a predetermined distance. For example, at least one first sphere (220) may be positioned at one edge of the first carrier (210), and at least one second sphere (230) may be positioned at the other edge of the first carrier (210). For example, at least one first sphere (220) may be positioned adjacent to one end of a first side (e.g., a side facing the -x-axis direction) of the first carrier (210), and at least one second sphere (230) may be positioned adjacent to the other end of the first side of the first carrier (210).

[0070] According to one embodiment, the size of at least one first sphere (220) may have a first size. The size of at least one second sphere (230) may have a second size. The second size may be substantially equal to or smaller than the first size, but is not limited thereto. For example, the second size may be larger than the first size.

[0071] According to one embodiment, the number of first spheres (220) disposed between the first carrier (210) and the housing may be the same as or different from the number of second spheres (230).

[0072] According to one embodiment, a first magnet (221) may be disposed on a first side (e.g., a side facing the -x-axis direction) of a first carrier (210). The first magnet (221) may be disposed to face a first coil (222). The first coil (222) may be disposed in a housing (e.g., the housing (130) of FIG. 2) facing the first side of the first carrier (210) on which the first magnet (221) is disposed. The first carrier (210) may be moved relative to the housing (e.g., the housing (130) of FIG. 2) (or the lens assembly (110), the optical refractive member (120), or the carrier (140)) by a force in a first direction (e.g., the z-axis direction or the -z-axis direction) acting on the first magnet (221) due to a magnetic field generated by a current flowing in the first coil (222). As the first carrier (210) moves, the image sensor can be moved in the first direction. As the first carrier (210) moves, the distance from the optical refractive member (120) to the image sensor can be changed.

[0073] According to one embodiment, the first carrier (210) may include a first guide portion (240) on a first side (e.g., a side facing the -x-axis direction). The first guide portion (240) may be formed in a first direction so that the first carrier (210) can move in the first direction (the z-axis direction or the -z-axis direction). In one example, the first guide portion may have a guide groove or rail shape, but is not limited thereto.

[0074] According to one embodiment, at least one first sphere (220) may be placed on a first guide portion (240). The first guide portion (240) may guide the at least one first sphere (220) to move in a first direction. For example, the at least one first sphere (220) may move, roll, rotate, or tilt on the first guide portion (240).

[0075] According to one embodiment, the first carrier (210) can be transported in the first direction by guiding at least one first sphere (220) along the first guide portion (240). When the first carrier (210) is transported in the first direction, at least a portion of the second driving units (e.g., the second carrier (310)) disposed on the first carrier (210) can be transported in the first direction. By the movement of at least a portion of the second driving units, the image sensor (e.g., the image sensor (160) of FIG. 2) can be transported in the first direction. Although not illustrated in FIG. 3, the housing (e.g., the housing (130) of FIG. 2) may include a guide portion formed at a position corresponding to the first guide portion (240) of the first carrier (210).

[0076] According to one embodiment, the first carrier (210) may further include a second guide portion (250) on a first side (e.g., a side facing the -x-axis direction). The second guide portion (250) may be formed in a first direction so that the first carrier (210) may move in the first direction (the z-axis direction or the -z-axis direction). In one example, the second guide portion may have a guide groove or rail shape, but is not limited thereto.

[0077] According to one embodiment, at least one second sphere (230) may be placed on the second guide portion (250). The second guide portion (250) may guide the at least one second sphere (230) to move in the first direction. For example, the at least one second sphere (230) may move, roll, rotate, or tilt on the second guide portion (250).

[0078] According to one embodiment, the first carrier (210) can be transported in the first direction by guiding at least one second sphere (230) along the second guide portion (250). When the first carrier (210) is transported in the first direction, at least a portion of the second driving units (e.g., the second carrier (310)) disposed on the first carrier (210) can be transported in the first direction. By the movement of at least a portion of the second driving units, the image sensor (e.g., the image sensor (160) of FIG. 2) can be transported in the first direction. Although not illustrated in FIG. 3, the housing (e.g., the housing (130) of FIG. 2) may further include a guide portion formed at a position corresponding to the second guide portion (250) of the first carrier (210).

[0079] According to one embodiment, at least one second guide part (250) may be arranged to be spaced apart from at least one first guide part (240) by a predetermined distance. For example, at least one first guide part (240) may be arranged (or formed) at one edge of the first carrier (210), and at least one second guide part (250) may be arranged (or formed) at the other edge of the first carrier (210). For example, at least one first guide part (240) may be arranged (or formed) adjacent to one end of a first side (e.g., a side facing the -x-axis direction) of the first carrier (210), and at least one second guide part (250) may be arranged (or formed) adjacent to the other end of the first side of the first carrier (210). According to one embodiment, the first magnet (221) may be arranged between at least one first guide part (240) and at least one second guide part (250).

[0080] According to one embodiment, the number of contact points of at least one second guide portion (250) that contacts at least one second sphere (230) may be substantially equal to or greater than the number of contact points of at least one first guide portion (240) that contacts at least one first sphere (220). For example, the first guide portion (240) may include a 'U' shaped groove, and the second guide portion (250) may include a 'V' shaped groove. At least one guide portion of the housing that faces the first guide portion (240) and contacts at least one first sphere (220) may include a 'V' shaped groove, and at least one other guide portion of the housing that faces the second guide portion (250) and contacts at least one second sphere (230) may include a 'V' shaped groove. However, the present invention is not limited thereto. For example, the first guide portion (240) may include a 'V' shaped groove, and the second guide portion (250) may include a 'V' shaped groove. At least one guide portion of the housing facing the first guide portion (240) and in contact with at least one first sphere (220) may include a 'U' shape, and at least one guide portion of the housing facing the second guide portion (250) and in contact with at least one second sphere (230) may include a 'V' shaped groove.

[0081] According to one embodiment, the first carrier (210) may have a first length (R1) in a first direction (e.g., the z-axis direction or the -z-axis direction). The sum of the lengths of at least one first sphere (220) in the first direction may have a second length (R2). For example, referring to FIG. 3, when the first driving unit (200) includes two first spheres (220), the sum of the lengths of the two first spheres (220) in the first direction may have a second length (R2). The sum of the lengths of at least one second sphere (230) in the first direction may have a third length (R3). For example, referring to FIG. 3, when the first driving unit (200) includes three second spheres (230), the sum of the lengths of the three second spheres (230) in the first direction may have a third length (R3). The first carrier (210) can move in the first direction by a fourth length (R4).

[0082] According to one embodiment, the sum of the larger length of the second length (R2) and the third length (R3) and the fourth length (R4) may be less than the first length (R1). For example, referring to FIG. 3, when the third length (R3) is greater than the second length (R2), the sum of the third length (R3) and the fourth length (R4) may be less than the first length (R1). In one example, when the first driving unit (200) includes only at least one first sphere (220), the sum of the lengths of the at least one first sphere (220) in the first direction (R2) and the sum of the fourth length (R4) may be less than the first length (R1).

[0083] FIG. 4 is a drawing for explaining the arrangement of a yoke included in a camera module according to one embodiment.

[0084] The camera module of FIG. 4 may be referred to as the camera module of FIGS. 1 to 3. The same terms and / or reference numerals are used for the same or substantially the same configurations as those described above, and any duplicate descriptions are omitted.

[0085] Referring to FIGS. 3 and 4, a camera module according to one embodiment may include a first yoke (224) positioned to face a first magnet (e.g., the first magnet (221) of FIG. 3). For example, the first magnet (221) may face a first coil (222) and the first yoke (224). In one example, the first yoke (224) may be positioned in a housing (e.g., the housing (130) of FIG. 2) that faces a first side of the first carrier (210) on which the first magnet (221) is positioned. In one example, the first yoke (224) may also be positioned in the first coil (222).

[0086] According to one embodiment, a magnetic force may be formed between the first yoke (224) and the first magnet (221). For example, a magnetic attraction may be formed between the first yoke (224) and the first magnet (221). Due to the magnetic attraction formed between the first yoke (224) and the first magnet (221), the first carrier (210) may not be separated from the housing. Due to the magnetic attraction formed between the first yoke (224) and the first magnet (221), at least one first sphere (e.g., at least one first sphere (220) of FIG. 3) may not be separated from at least one first guide portion (e.g., at least one first guide portion (240) of FIG. 3). By the magnetic attraction formed between the first yoke (224) and the first magnet (221), at least one second sphere (e.g., at least one second sphere (230) of FIG. 3) may not be separated from at least one second guide portion (e.g., the second guide portion (250) of FIG. 3).

[0087] In one embodiment, the camera module may include a second yoke (225) positioned to face a first magnet (e.g., the first magnet (221) of FIG. 3). The second yoke (225) may be positioned between the first yoke (224) and at least one first sphere (e.g., the at least one first sphere (220) of FIG. 3). In one example, the second yoke (225) may be positioned in a housing (130) facing a first side of a first carrier (210) on which the first magnet (221) is positioned. In one example, the second yoke (225) may also be positioned in a first coil (222).

[0088] According to one embodiment, at least one of the first yoke (224) or the second yoke (225) can reduce the rattling (tilt phenomenon) that occurs when the first carrier (the first carrier (310) of FIG. 3) moves in the first direction.

[0089] According to one embodiment, the second yoke (225) may be positioned at a biased position relative to at least one second sphere (the second sphere (230) of FIG. 3) than to at least one first sphere (the first sphere (220) of FIG. 3). For example, the second yoke (225) may be positioned closer to at least one second sphere (230) than to at least one first sphere (220). For example, the second yoke (225) may be positioned closer to at least one second guide portion (the second guide portion (250) of FIG. 3) than to at least one first guide portion (the at least one first guide portion (240) of FIG. 3). For example, the distance from the second yoke (225) to the at least one first guide portion (240) may be substantially equal to or greater than the distance from the second yoke (225) to the at least one second guide portion (250).

[0090] According to one embodiment, at least one of the first yoke (224) or the second yoke (225) may be configured to generate a biased magnetic force (e.g., magnetic attraction) with respect to the first magnet (e.g., the first magnet (221) of FIG. 3) so that the first carrier (e.g., the first carrier (310) of FIG. 3) can move stably. For example, at least one of the first yoke (224) or the second yoke (225) may form a stronger magnetic force in a region adjacent to at least one second guide portion (the second guide portion (250) of FIG. 3) than in a region adjacent to at least one first guide portion (the first guide portion (240) of FIG. 3). Accordingly, the first carrier (e.g., the first carrier (210) of FIG. 3) can move in close contact with at least one second sphere (at least one second sphere (230) of FIG. 3) by the biased magnetic force formed between the first yoke (224) and the second yoke (225) and the first magnet (e.g., the first magnet (221) of FIG. 3).

[0091] According to one embodiment, at least one of the first yoke (224) or the second yoke (225) may be disposed on one side (e.g., one side in the -y-axis direction) of the winding center of the first coil (e.g., the first coil (222) of FIG. 3). Since at least one of the first yoke (224) or the second yoke (225) is concentrated on one side of the winding center of the first coil (222), the magnitude of the biased magnetic force generated between the first magnet (e.g., the first magnet (221) of FIG. 3) and at least one of the first yoke (224) or the second yoke (225) may increase.

[0092] According to one embodiment, at least one of the first yoke (224) or the second yoke (225) may be formed with a first direction (e.g., the z-axis direction or the -z-axis direction) as its longitudinal direction. Accordingly, even if the first carrier (e.g., the first carrier (210) of FIG. 3) moves in the first direction, a biased magnetic force may be generated between the first magnet (e.g., the first magnet (221) of FIG. 3) and at least one of the first yoke (224) or the second yoke (225).

[0093] According to one embodiment, at least one of the first yoke (224) or the second yoke (225) may have an asymmetrical left-right area. For example, at least one of the first yoke (224) or the second yoke (225) may have an asymmetrical area in the y-axis direction. For example, at least one of the first yoke (224) or the second yoke (225) may include a first portion that is closer to at least one second sphere (the first sphere (230) of FIG. 3) than to at least one first sphere (the first sphere (220) of FIG. 3), and a second portion that is closer to at least one first sphere (220) than to at least one second sphere (230). The area of ​​the first portion of at least one of the first yoke (224) or the second yoke (225) may be substantially equal to or larger than the area of ​​the second portion. Therefore, the first part may have a stronger attractive force with the first magnet (e.g., the first magnet (221) of FIG. 3) than the second part.

[0094] According to one embodiment, the mass of at least one first portion of the first yoke (224) or the second yoke (225) may be substantially equal to or greater than the mass of the second portion. For example, the thickness of the first portion may be substantially equal to or greater than the thickness of the second portion. Accordingly, the first portion may have a stronger attractive force with the first magnet (e.g., the first magnet (221) of FIG. 3) than the second portion.

[0095] According to one embodiment, a first carrier (e.g., a first carrier (210) of FIG. 3) can selectively contact at least one sphere by a biased attraction between a first magnet (e.g., a first magnet (221) of FIG. 3) and at least one of a first yoke (224) or a second yoke (225). For example, the first carrier (210) may always contact at least one second sphere (e.g., at least one second sphere (230) of FIG. 3), but may selectively contact at least one first sphere (at least one first sphere (220) of FIG. 3).

[0096] According to one embodiment, at least one of the first yoke (224) or the second yoke (225) may include a material that is magnetic in a magnetic field. For example, at least one of the first yoke (224) or the second yoke (225) may include a material that forms an attractive force with the first magnet (e.g., the first magnet (221) of FIG. 3).

[0097] According to one embodiment, the shape of the first yoke (224) or the second yoke (225) is not limited to the shape illustrated in FIG. 4. For example, at least one of the first yoke (224) or the second yoke (225) may have a rectangular shape, as illustrated in FIG. 4, but is not limited thereto. For example, the second yoke (225) may include a protrusion protruding in one direction from the first yoke (224).

[0098] According to one embodiment, in FIG. 4, the second yoke (225) is depicted as being spaced apart from the first yoke (224) by a predetermined distance, but this is not limited thereto. For example, the second yoke (225) may at least partially contact the first yoke (224). For example, the second yoke (225) may be one member with the first yoke (224).

[0099] According to one embodiment, the camera module may include a second yoke (225) so that an external force that interferes with AF operation may be overcome. For example, when a printed circuit board (e.g., the printed circuit board (170) of FIG. 2) moves together with an image sensor (e.g., the image sensor (160) of FIG. 2), the printed circuit board (170) connected to the image sensor (160) may be warped. As the printed circuit board (170) is warped, an external force may be applied to the first carrier (e.g., the first carrier (210) of FIG. 3) so that the first carrier (210) may be warped. The second yoke (225) may generate a magnetic force that can overcome the external force so that the first carrier (210) is not warped.

[0100] According to one embodiment, the camera module may include a position sensor (223). The position sensor (223) may detect a position of at least one magnet (e.g., the first magnet (221) of FIG. 3). For example, the position sensor (223) may detect a magnetic field to detect a position of at least one magnet relative to at least one coil (e.g., the first coil (222) or the housing (130)). A control circuit electrically connected to the position sensor (223) may provide power to the position sensor (223). The control circuit may detect a position of at least one magnet via the position sensor (223).

[0101] FIG. 5 is a drawing showing a driving unit assembled with an image sensor (160) according to one embodiment.

[0102] The components of FIG. 5 may be referenced by the components of FIGS. 1 to 4 described above. The same terms and / or reference numerals are used for components that are identical or substantially identical to those described above, and redundant descriptions are omitted. For example, the first yoke (224) of FIG. 5 may be referenced by the first yoke (224) of FIG. 4.

[0103] Referring to FIG. 5, at least a portion of the second driving unit may be accommodated in the first driving unit. For example, at least a portion of the second carrier (310) may be accommodated in the first carrier (210). For example, the first carrier (210) may surround at least a portion of a side surface of the second carrier (310).

[0104] According to one embodiment, the image sensor (160) may be placed on a printed circuit board (170). For example, the image sensor (160) may be fixed to the printed circuit board (170).

[0105] According to one embodiment, the image sensor (160) and the printed circuit board (170) can move together with the first carrier (210). For example, the printed circuit board (170) on which the image sensor (160) is disposed is coupled with the second carrier (310), so that the image sensor (160) and the printed circuit board (170) can move together with the second carrier (310). For example, when the second carrier (310) moves in a second direction (e.g., in the x-axis direction or the -x-axis direction), the image sensor (160) and the printed circuit board (170) can move in the second direction. For example, when the second carrier (310) moves in a third direction (e.g., in the y-axis direction or the -y-axis direction), the image sensor (160) and the printed circuit board (170) can move in the third direction. For example, since the second carrier (310) is accommodated in the first carrier (210), when the first carrier (210) moves in the first direction (e.g., the z-axis direction or the -z-axis direction), the second carrier (310) can move in the first direction, and the image sensor (160) and the printed circuit board (170) can move in the first direction.

[0106] According to one embodiment, at least one of the first carrier (210) or the second carrier (310) may be open in a first direction. For example, at least one of the first carrier (210) or the second carrier (310) may have a portion corresponding to the image sensor (160) open in the first direction. For example, at least one of the first carrier (210) or the second carrier (310) may have a space formed in a portion corresponding to the image sensor (160). For example, when looking down at at least one of the first carrier (210) or the second carrier (310) from above (e.g., looking down in the -z-axis direction), the image sensor (160) may be visible.

[0107] According to one embodiment, an optical refractive member (e.g., an optical refractive member (120) of FIG. 3) may be disposed in at least one of the spaces (open portions) of the first carrier (210) or the second carrier (310). For example, referring to FIGS. 2 and 5, at least a portion of a carrier (e.g., a carrier (140) of FIG. 2) that accommodates the optical refractive member may be disposed in the space. For example, an opening (e.g., an opening (141) of FIG. 2) may be disposed in the space. The image sensor (160) may correspond at least partially to the opening (141).

[0108] According to one embodiment, the first carrier (210) may include a cover portion (211) that covers at least a portion of the first carrier (210). For example, the cover portion (211) may cover a surface of the first carrier (210) facing a first direction (e.g., the +z-axis direction).

[0109] According to one embodiment, the camera module (100) may include at least one elastic member (212) disposed between the first carrier (210) and the cover (e.g., the cover (150) of FIG. 2). For example, the at least one elastic member (212) may be disposed on a surface of the first carrier (210) facing the cover (150). For example, the at least one elastic member (212) may be disposed on a cover portion (211). However, the present invention is not limited thereto. For example, the at least one elastic member may be disposed on an inner surface of the cover (150) facing an upper surface (e.g., a surface facing the +z-axis direction) of the first carrier (210).

[0110] In one embodiment, at least one elastic member (212) can reduce or eliminate noise generated by the first carrier (210) colliding with another component (e.g., the cover (150) of FIG. 2). The at least one elastic member (212) can reduce or eliminate damage to the first carrier (210) and / or the other component due to the first carrier (210) colliding with the other component (e.g., the cover (150)).

[0111] FIG. 6 is a drawing for explaining the arrangement of an elastic member (212) included in a camera module according to one embodiment.

[0112] The components of FIG. 6 may be referenced by the components of FIGS. 1 to 5 described above. For example, the elastic member (212) of FIG. 6 may be referenced by the elastic member (212) of FIG. 5. The same terms and / or the same reference numerals are used for components that are identical or substantially identical to those described above, and any duplicate descriptions are omitted.

[0113] According to one embodiment, at least one elastic member (212) may be disposed at a corner portion of one surface of the first carrier (210). For example, at least one elastic member may be disposed at a corner portion of an upper surface (e.g., a surface facing the +z-axis direction) of the first carrier (210). Referring to FIG. 5, the elastic member (212) may be disposed at each corner portion of one surface of the first carrier (210).

[0114] According to one embodiment, at least one elastic member (212) may protrude from one surface of the first carrier (210). For example, the at least one elastic member may protrude in the +z-axis direction from the upper surface of the first carrier (210).

[0115] In one embodiment, at least one elastic member (212) may include an elastic material. For example, at least one elastic member (212) may include, but is not limited to, at least one of silicone and rubber. In one example, at least one elastic member (212) may include a spring.

[0116] FIG. 7 is a drawing for explaining a second driving unit (300) for driving OIS of a camera module according to one embodiment.

[0117] The camera module and its components of Fig. 7 may be referenced by the camera module and its components of Figs. 1 to 6 described above. Components that are identical or substantially identical to those described above are denoted by the same terminology and / or the same reference numerals, and any duplicate descriptions are omitted.

[0118] According to one embodiment, the camera module may include a second driving unit (300) for optical image stabilization. The second driving unit (300) may move an image sensor (e.g., the image sensor (160) of FIG. 5) in a second direction (e.g., the x-axis direction or the -x-axis direction) and / or a third direction (e.g., the y-axis direction or the -y-axis direction). The second direction and the third direction may be different directions, but the present invention is not limited thereto. In one example, the second driving unit (300) may rotate or tilt the image sensor about an optical axis (e.g., the z-axis). For example, the image sensor may rotate or tilt about the optical axis due to an electromagnetic interaction between a second magnet (321) and a second coil (322). For example, the image sensor can be rotated or tilted around the optical axis by the electromagnetic interaction between the third magnet (323) and the third coil (324).

[0119] The second driving unit (300) according to one embodiment may include an OIS actuator configured to move the image sensor for optical image stabilization. For example, the second driving unit (300) may move the image sensor in a direction substantially perpendicular to a first direction (e.g., a z-axis direction or a -z-axis direction) in which a distance between the optical refractive member and the image sensor changes for optical image stabilization.

[0120] According to one embodiment, the second driving unit (300) may include a second carrier (310) that transports an image sensor (e.g., the image sensor (160) of FIG. 5) in a second direction (e.g., the x-axis direction or the -x-axis direction). In one example, the image sensor (160) may be coupled to the second carrier (310).

[0121] According to one embodiment, a second magnet (321) may be placed on a first side (e.g., a side facing the third direction) of the second carrier (310). The second magnet (321) may be placed to face a second coil (322). The second coil (322) may be placed in a housing (e.g., housing (130) of FIG. 2) facing the first side of the second carrier (310) on which the second magnet (321) is placed. The second carrier (310) can be moved relative to the housing (e.g., the housing (130) of FIG. 2) (or the lens assembly (110), the optical refractive member (120), or the carrier (140)) by a force in a third direction (e.g., the y-axis direction or the -y-axis direction) acting on the second magnet (321) due to a magnetic field generated by a current flowing in the second coil (322). As the second carrier (310) moves, the image sensor (e.g., the image sensor (160) of FIG. 5) can be moved in the third direction.

[0122] According to one embodiment, a third magnet (323) may be placed on a second side (e.g., a side facing the second direction) of the second carrier (310). The third magnet (323) may be placed to face a third coil (324). The third coil (324) may be placed in a housing (e.g., housing (130) of FIG. 2) facing the second side of the second carrier (310) on which the third magnet (323) is placed. The second carrier (310) can be moved relative to the housing (e.g., the housing (130) of FIG. 2) (or the lens assembly (110), the optical refractive member (120), or the carrier (140)) by a force in a second direction (e.g., in the x-axis direction or the -x-axis direction) acting on the third magnet (323) due to a magnetic field generated by a current flowing in the third coil (324). As the second carrier (310) moves, the image sensor (e.g., the image sensor (160) of FIG. 5) can be moved in the second direction.

[0123] According to one embodiment, the first side of the second carrier (310) can be substantially perpendicular to the second side of the second carrier (310). The second magnet (321) can be arranged to be substantially perpendicular to the third magnet (323). The second coil (322) can be arranged to be substantially perpendicular to the third coil (324).

[0124] According to one embodiment, a first side of the second carrier (310) can be substantially perpendicular to a first side (e.g., a side facing the -x-axis direction) on which a first magnet (e.g., the first magnet (221) of FIG. 3) (or at least one first sphere (220)) of the first carrier (210) is disposed. The second magnet (321) can be disposed substantially perpendicular to the first magnet (221). The second coil (322) can be disposed substantially perpendicular to the first coil (222). The third magnet (323) can be disposed opposite the first magnet (221). The third magnet (323) can be disposed substantially parallel to the first magnet (221). The third coil (324) can be disposed opposite the first coil (222). The third coil (324) can be disposed substantially parallel to the first coil (222). However, it is not limited to this.

[0125] Fig. 8 is a drawing for explaining an elastic member (214) according to one embodiment. Fig. 9 is a drawing schematically illustrating an elastic member (214) according to one embodiment.

[0126] The camera modules and components thereof of FIGS. 8 and 9 may be referenced by the camera modules and components thereof of FIGS. 1 to 7 described above. The same terms and / or reference numerals are used for components that are identical or substantially identical to those described above, and any duplicate descriptions are omitted.

[0127] According to one embodiment, the first carrier (210) may include at least one elastic member (214) formed between at least one first guide portion in which at least one first sphere (220) is arranged and at least one second guide portion in which at least one second sphere (230) is arranged.

[0128] According to one embodiment, at least one elastic member (214) may be formed on the first side (213) of the first carrier (210). The at least one elastic member (214) may be positioned between a portion of the first side (213) of the first carrier (210) that receives an impact (F). For example, the at least one elastic member (214) may be positioned between a portion of the first carrier (210) that receives an impact (F) from the second carrier (310). For example, the at least one elastic member (214) may be formed between at least one first guide portion of the first side (213) and a portion where the first magnet (221) is positioned. For example, the at least one elastic member (214) may be formed between at least one second guide portion of the first side (213) and a portion where the first magnet (221) is positioned. For example, at least one elastic member (214) may be formed in a portion between at least one first guide portion of the first side (213) and a portion where the first magnet (221) is arranged, and in a portion between at least one second guide portion and a portion where the first magnet (221) is arranged.

[0129] According to one embodiment, at least one elastic member (214) is positioned between the portion of the first side (213) of the first carrier (210) that receives the impact (F), thereby reducing or preventing damage to at least a portion of the first driving member (e.g., at least one of the first magnet (221), the first coil (222), the at least one first sphere (230), or the at least one second sphere (220)) or the housing (e.g., the housing (130) of FIG. 2).

[0130] According to one embodiment, the thickness of at least one elastic member (214) may be gradually thinned. For example, the length of at least one elastic member (214) in the second direction (e.g., the x-axis direction) may be gradually reduced toward the portion of the first side (213) of the first carrier (210) that receives the impact (F).

[0131] According to one embodiment, at least one elastic member (214) may have a lower stiffness than other portions of the first side (213) of the first carrier (210). For example, at least one elastic member (214) may have a thinner thickness than other portions of the first side (213). For example, at least one elastic member (214) may have a shorter length in the second direction (e.g., in the x-axis direction) than other portions.

[0132] According to one embodiment, at least one elastic member (214) may include a material having lower rigidity than other portions of the first side (213) of the first carrier (210). For example, at least one elastic member (214) may include a material having elasticity. For example, at least one elastic member (214) may include at least one of rubber or silicone.

[0134] According to one embodiment, the first side (213) may include a first elastic member (214) disposed between at least one second guide portion having at least one second sphere (230) disposed and a portion of the first side (213) that receives an impact (F) (e.g., a portion having a first magnet (221) disposed), and a second elastic member (215) disposed between at least one first guide portion having at least one first sphere (220) disposed and a portion of the first side (213) that receives an impact (F).

[0135] According to one embodiment, at least one elastic member (214, 215) may be a separate member from the first side (213). For example, at least one of the first elastic member (214) or the second elastic member (215) may be a separate member from the first side (213). For example, at least one of the first elastic member (214) or the second elastic member (215) may include a different material from the first side (213). However, the present invention is not limited thereto. For example, at least one of the first elastic member (214) or the second elastic member (215) may be a single member from the first side (213). For example, at least one of the first elastic member (214) or the second elastic member (215) may include the same material as the first side (213).

The second driving unit for OIS driving may include a second carrier (810) coupled with an image sensor (660), and a third carrier (810a) that transports the second carrier (810) in a third direction (e.g., in the y-axis direction or the -y-axis direction). For example, the second carrier (810) may be disposed on the third carrier (810a), such that as the third carrier (810a) moves in the third direction, the second carrier (810) may be transported in the third direction.

[0146] According to one embodiment, with reference to FIG. 11, at least one third sphere (820) may be disposed between the second carrier (810) and the third carrier (810a). The second carrier (810) may be moved on the third carrier (810a) by the at least one third sphere (820). For example, the second carrier (810) may be moved in a second direction (e.g., in the x-axis direction or the -x-axis direction) with respect to the cover (650) or the optical refractive member (620) by the at least one third sphere (820). However, the present invention is not limited thereto. For example, in the camera module according to one embodiment, the third carrier (810a) and at least one third sphere (820) may be omitted.

By guiding (e.g., moving, rolling, rotating, or tilting) the at least one third sphere (820) disposed between the second carrier (810) and the third carrier (810a) along the at least one third guide portion (840), the second carrier (810) may move in the second direction. When the second carrier (810) moves in the second direction, the image sensor (660) accommodated in the second carrier (810) can move together in the second direction.

[0148] According to one embodiment, at least one fourth sphere (830) may be disposed between the first carrier (710) and the third carrier (810a). The third carrier (810a) may be movable on the first carrier (710) by the at least one fourth sphere (830).

[0149] According to one embodiment, at least one of the first carrier (710) or the third carrier (810a) may include at least one fourth guide portion (not shown) that guides at least one fourth sphere (830) to move in a third direction. The at least one fourth sphere (830) may be disposed on the at least one fourth guide portion. The at least one fourth sphere (830) disposed between the first carrier (710) and the third carrier (810a) may be guided (e.g., moved, rolled, rotated, or tilted) along the at least one fourth guide portion, thereby allowing the third carrier (810a) to move in the third direction. When the third carrier (810a) moves in the third direction, the second carrier (810) accommodated in the third carrier (810a) may be transported together in the third direction. When the second carrier (810) is transported in the third direction, the image sensor (660) accommodated in the second carrier (810) can be transported together in the third direction.

[0150] Referring to FIG. 12, the third carrier (810a) according to one embodiment may have an 'L' shape. For example, the third carrier (810a) may include a first portion (811a) facing the first magnet (821), and a second portion (811b) extending from the first portion (811a). The first portion (811a) may be arranged to be substantially parallel to the first magnet (821), and the second portion (811b) may be arranged to be substantially perpendicular to the first magnet (821). However, the shape of the third carrier (810a) is not limited thereto. For example, the third carrier (810a) may have a 'ㄷ' shape or a 'ㅁ' shape.

By covering at least a portion of the housing (1030), a space can be formed therein. Various components of the camera module can be arranged within the space formed by the housing (1030) and the cover (1050).

[0166] According to one embodiment, at least one of the housing (1030) or the cover (1050) can limit the range of movement of the driving unit of the camera module.

[0167] According to one embodiment, referring to FIG. 14, the first carrier (1110) can have a first length (D1) in a first direction (e.g., in the z-axis direction or the -z-axis direction). For example, a second side of the first carrier, which faces in the opposite direction (e.g., in the +x direction) of a first side of the first carrier (e.g., the first side of the first carrier (210) of FIG. 3), can have the first length (D1) in the first direction (e.g., the first length (R1) of FIG. 3).
