Description

Camera device and optical device including same

[0001] The embodiment relates to a camera device and an optical device including the same.

[0002] A camera device is a device that captures a subject as a photo or video, and is installed on portable devices, drones, vehicles, etc. In order to improve the quality of the image, the camera device may have an image stabilization (IS) function, such as an optical image stabilizer (OIS), an autofocus (AF) function, and / or a zooming function, which compensates for or prevents image shaking caused by the user's movements.

[0003] The embodiment provides a camera device and an optical device including the same, which can reduce power consumption, stably support an OIS moving part, and prevent a holder or an optical member from being damaged by collision with a driving plate.

[0004] A camera device according to an embodiment includes a housing; a holder disposed within the housing; an optical member disposed in the holder; a support member coupled to the holder; a driving plate disposed between the housing and the support member and spaced apart from the holder; a first magnetic body disposed in the holder; and a second magnetic body disposed in the housing and facing the first magnetic body in a first direction.

[0005] The optical member may be arranged closer to the first magnetic body than the driving plate. The optical member may be arranged closer to the second magnetic body than the driving plate. A repulsive force may be applied between the first magnetic body and the second magnetic body in the first direction. At least a portion of the support member may pass through the housing and be coupled to the holder. The driving plate may not overlap the holder in a direction perpendicular to the first direction.

[0006] The support portion includes a body and an extension portion extending from the body and coupled with the holder, and at least a portion of the driving plate can be in contact with the body. At least a portion of the driving plate overlaps the support portion in a second direction, the second direction being perpendicular to the first direction and being a direction in which light is incident on the optical member.

[0007] The housing includes a first side facing the emission surface of the optical member and a second side positioned opposite the first side in the first direction, the support portion passes through the second side of the housing and is coupled to the holder, and the driving plate can be disposed between the second side of the housing and the support portion.

[0008] The driving plate may include a first protrusion protruding toward the second side of the housing and a second protrusion protruding toward the support portion, the housing may include a first groove disposed at the second side and in which at least a portion of the first protrusion is disposed, and the support portion may include a second groove in which at least a portion of the second protrusion is disposed.

[0009] The second magnetic body may be disposed on the second side of the housing, and the first magnetic body may be disposed on the side of the holder opposite the second side of the housing.

[0010] At least a portion of the driving plate may be disposed on the outside of the housing. The second magnetic body may be positioned between the first magnetic body and the driving plate. The housing may include a first portion disposed between the second magnetic body and the driving plate. The driving plate may include a first protrusion protruding toward the first portion of the housing and a second protrusion protruding toward the support portion, and at least a portion of the first protrusion may be disposed on the first portion and at least a portion of the second protrusion may be disposed on the support portion.

[0011] The distance between the optical member and the driving plate may be greater than the distance between the optical member and the first magnetic body. The driving plate may not overlap the optical member in a direction perpendicular to the first direction. The optical member may be a prism or a mirror.

[0012] According to another embodiment, a camera device includes a housing; a holder disposed within the housing; an optical member disposed in the holder; a first magnetic body disposed on a first side of the holder; a second magnetic body disposed on a first side of the housing opposite to the first side of the holder; a support member passing through the first side of the housing and coupled to the first side of the holder; and a driving plate disposed between the first side of the housing and the support member. A repulsive force may be applied between the first magnetic body and the second magnetic body.

[0013] The first magnetic body may be positioned on the inside of the housing, and at least a portion of the driving plate may be positioned on the outside of the housing.

[0014] In an embodiment, the drive plate may be positioned on the outside of the housing, thereby allowing the drive plate, which is the rotational axis, to be positioned away from the holder, which is the OIS moving part.

[0015] In the embodiment, since the drive plate is positioned far from the OIS moving unit, the moving distance of the OIS moving unit required for image stabilization can be reduced, and the power consumption required to move the OIS moving unit can be reduced.

[0016] In addition, in the embodiment, the size of the driving plate can be designed to be large, and the OIS moving part can be stably supported and guided.

[0017] Additionally, in the embodiment, the drive plate does not directly contact the holder and the drive plate and the holder do not directly collide due to impact. As a result, the embodiment can suppress or prevent damage to the holder and optical member due to collision with the drive plate.

[0054] Hereinafter, embodiments of the present invention that can specifically achieve the above purpose will be described with reference to the attached drawings.

[0055] In the description of the embodiments, when it is described that each element is formed "on or under", "on or under" includes both cases where two elements are in direct contact with each other or where one or more other elements are formed by being disposed indirectly between the two elements. In addition, when it is expressed as "on or under", it can include the meaning of not only the upward direction but also the downward direction based on one element.

[0056] Additionally, relational terms such as “first” and “second,” “upper / upper / lower,” and “lower / lower / below” used hereinafter may be used only to distinguish one entity or element from another entity or element, without necessarily requiring or implying any physical or logical relationship or order between such entities or elements. In addition, the same reference numbers represent the same elements throughout the description of the drawings.

[0057] Furthermore, terms such as "include," "comprise," or "have" described above, unless specifically stated otherwise, imply that the corresponding component may be included, and thus should be interpreted to include other components rather than excluding other components. Furthermore, terms such as "corresponding" described above may include at least one of the meanings of "opposite" or "overlapping."

[0058] Hereinafter, a camera device according to an embodiment and an optical device including the same will be described with reference to the attached drawings. For convenience of explanation, the camera device according to the embodiment will be described using a Cartesian coordinate system (x, y, z), but may be described using another coordinate system, and the embodiment is not limited thereto. In each drawing, the X-axis and the Y-axis may mean a direction perpendicular to the Z-axis, which is the direction of the optical axis (OA). In addition, the Z-axis direction, which is the direction of the optical axis (OA), may be referred to as a “first direction,” the X-axis direction may be referred to as a “second direction,” and the Y-axis direction may be referred to as a “third direction.” In addition, the Y-axis may be referred to as a “first axis,” the Y-axis direction may be referred to as a “first-axis direction,” the X-axis may be referred to as a “second-axis direction,” and the X-axis direction may be referred to as a “second-axis direction.” For example, the optical axis direction may be a direction of the optical axis or a direction parallel to the optical axis.

[0059] Additionally, the term "terminal" below may be expressed as a pad, electrode, or conductive layer. Additionally, the term "code value" below may be expressed as data or a digital value.

[0060] In addition, in the embodiment, in the coupling between the protrusion and the hole for coupling two components to each other, one of the components may be a coupling protrusion (or coupling hole), and the other side may be a corresponding coupling hole (or coupling protrusion).

[0061] A camera device according to an embodiment may perform a shake correction function, an auto-focusing function, and a zoom function. The 'shake correction function' may be a function that moves a lens in a direction perpendicular to the optical axis direction or tilts the lens with respect to the optical axis to offset vibration (or movement) caused by the user's shaking hand. In addition, the 'auto-focusing function' may be a function that automatically focuses on a subject by moving the lens in the optical axis direction according to the distance of the subject to obtain a clear image of the subject on the image sensor. The 'zoom function' may be a zooming function that takes pictures by increasing or decreasing the magnification of a distant subject through a zoom lens.

[0062] Hereinafter, “camera device” may be replaced with “camera”, “camera module”, “camera camera” or “camera”.

[0063] FIG. 1 is a perspective view of a camera device (200) according to an embodiment, FIG. 2 is an exploded perspective view of the camera device (200) of FIG. 1, and FIG. 3 is a cross-sectional view of the camera device in the AB direction of FIG. 1.

[0064] Referring to FIGS. 1 to 3, the camera device (200) may include a first actuator (310), a second actuator (320), and an image sensing unit (330).

[0065] The second actuator (320) may include a fixed portion and an OIS moving portion. The OIS moving portion (100) may be alternatively expressed as a “moving portion,” “swinging portion,” or “moving portion.”

[0066] The fixed member may be a fixed element. That is, the fixed member may not move in the direction of the optical axis (e.g., the Z-axis direction). In addition, the fixed member may not move in a direction intersecting the optical axis (e.g., the X-axis direction or the Y-axis direction). In addition, the fixed member may not tilt with respect to an axis intersecting the optical axis (e.g., the X-axis or the Y-axis). In addition, a component coupled to the fixed member may also correspond to the fixed member. For example, the fixed member may include a first housing (50). In addition, the fixed member may include components coupled to the first housing (50), such as a substrate (250). In addition, the fixed member may include components coupled to the substrate (250), such as an OIS coil (230), a position sensor (240), a magnetic body (63), a gyro sensor (82), or a second driver (260).

[0067] The OIS moving unit can tilt or rotate within a preset angular range about at least one axis intersecting the optical axis with respect to the fixed unit. The OIS moving unit can move left and right or tilt about a first axis intersecting the optical axis with respect to the fixed unit. Furthermore, the OIS moving unit can move left and right or tilt about a second axis intersecting the optical axis with respect to the fixed unit. For example, the first axis can be perpendicular to the optical axis direction, and the second axis can intersect the optical axis direction and the first axis. For example, the first axis can be the X-axis (or Y-axis), and the second axis can be the Y-axis (or X-axis). In other embodiments, each of the first axis and the second axis can intersect the X-axis or the Y-axis. For example, the first axis and the second axis can be perpendicular to each other.

[0068] The OIS moving unit may include an optical member (40). The OIS moving unit may include a holder (30). For example, the OIS moving unit may include components that are coupled or connected to the holder (30). For example, the OIS moving unit may include at least one of a magnet (31, 32), a magnetic body (31), and a yoke (33). The OIS moving unit may also include a support coupling unit (60).

[0069] The second actuator (320) can move the optical member (40), thereby performing an OIS (Optical Image Stabilizer) operation for performing shake correction, and may be expressed as a “second driving unit,” “OIS driving unit,” or “shake correction driving unit.”

[0070] The second actuator (320) can change the path of light. For example, the second actuator (320) may include an optical member (40) that changes the path of light. The second actuator (320) may also be referred to as an “optical path changing unit.”

[0071] The first actuator (310) can move the lens assemblies (312, 313) in the optical axis direction, thereby performing auto focus and / or zoom functions, and may be alternatively expressed as a “first driving unit” or an “AF and zoom driving unit.” The first actuator (310) may be expressed as a “second actuator,” and the second actuator (320) may be expressed as a “first actuator.”

[0072] For example, the first actuator (310) may be placed at the rear end of the second actuator (320) and may be coupled with the second actuator (320). For example, the first actuator (310) may be placed between the image sensor (540) and the second actuator (320).

[0073] The image sensing unit (330) can receive and detect light that has passed through the optical member (40) of the second actuator (320) and the lens assemblies (311, 312, 313) of the first actuator (310), and convert the detected light into an electrical signal. The image sensing unit (330) can detect light that has passed through the optical member (40) of the second actuator (320) and the lens assemblies (311, 312, 313) of the first actuator (310).

[0074] The camera device (200) may further include a cover member (300). The cover member (300) may be in the shape of a box having an open bottom and including a top plate (301) and a side plate (302). The cover member (300) may accommodate the first actuator (310), the second actuator (320), and the image sensing unit (330) of the camera device (200).

[0075] An opening (303) or hole exposing the incident surface of the optical member (40) may be formed in the upper plate (301) of the cover member (300).

[0076] Additionally, the camera device (200) may further include a bracket (not shown) for accommodating the first actuator (310), the second actuator (320), and the image sensing unit (330).

[0077] The cover member (300) may be formed of a metal plate, but is not limited thereto, and may be formed of a plastic or resin material. In addition, the cover member (300) may be formed of a material that blocks electromagnetic waves.

[0078] The camera device (200) is placed on the upper plate (301) of the cover member (300) and may further include a protective film (not shown) covering the opening (303) of the cover member (300). The protective film may be formed of a light-transmitting material, may prevent foreign substances from entering the camera device (200), and may protect the optical member (40) from impact, etc.

FIG. 12 is a cross-sectional view of the second actuator (320) in the CD direction of FIG. 4, and FIG. 13 is a cross-sectional view of the second actuator (320) in the EF direction of FIG. 4.

[0080] Referring to FIGS. 4 to 13, the second actuator (320) may include an optical member (40) and a second driving unit (70) that rotates the optical member (40) by a preset angle in a direction (e.g., X-axis direction or Y-axis direction) intersecting the optical axis direction (e.g., Z-axis direction).

[0081] The optical member (40) can serve to change the path of light. For example, the optical member (40) can receive light passing through the opening (303) of the cover member (300) and emit the received light toward the first actuator (310).

[0082] The optical member (40) may include a reflector capable of changing the direction of light propagation. For example, the optical member (40) may be a prism that reflects light, but is not limited thereto, and in other embodiments, may be a mirror or a reflector.

[0083] An optical member (40) can be placed in the holder (30). The optical member (40) can change the optical path of incident light into an optical axis parallel to the central axis (Z) of the lens portion, thereby changing the incident light into parallel light, and the parallel light can pass through the first lens assembly (640), the second lens assembly (622), and the third lens assembly (624) to reach the image sensor (540).

[0084] Referring to FIG. 5, for example, the optical member (40) may include an incident surface (8A) and an exit surface (8B), and may reflect light incident on the incident surface (8A) and emit it through the exit surface (8B). For example, the optical member (40) may be a right-angled prism including an incident surface (8A), a reflective surface (8C), and an exit surface (8B). For example, the interior angle between the incident surface (8A) and the exit surface (8B) may be a right angle.

[0085] Also, for example, the first internal angle between the incident surface (8A) and the reflective surface (8C) and the second internal angle between the exit surface (8B) and the reflective surface (8C) may each be 30 to 60 degrees. For example, the first internal angle and the second internal angle may each be 45 degrees, but are not limited thereto. In addition, due to the change in the optical path by the optical member (40), the thickness of the camera device (200) in the direction perpendicular to the incident surface (8A) of the optical member (40) can be reduced, and thus the thickness of the mobile device or terminal (200A) on which the camera device (200) is mounted can be reduced.

[0086] For example, the second actuator (320) may include a first housing (50), a holder (30) disposed within the first housing (50), an optical member (40) disposed within the holder (30), and a support coupling member (60) disposed between the holder (30) and the housing (50). In addition, the second actuator (320) may include a second driving member (70).

[0087] Referring to FIGS. 5 and 6A to 6C, the holder (30) may include a mounting portion (104) for placing or mounting an optical member (40). The mounting portion (104) may be in the form of a groove and may have a mounting surface (104a) (or mounting surface) for placing a reflective surface (8C) of the optical member (40). For example, the mounting surface (104a) may be an inclined surface inclined with respect to the optical axis direction.

[0088] For example, an adhesive for attaching an optical member (40) to a mounting surface (104a) of a holder (30) may be placed, and at least one groove (104b) for receiving the adhesive may be formed in the mounting surface (104a).

[0089] The holder (30) may include first to fourth side portions (31a to 31d) (or first to fourth side portions). The first side portion (31a) and the second side portion (31b) may be positioned facing or opposite to each other in the first direction. The third and fourth side portions (31c, 31d) may be positioned between the first side portion (31a) and the second side portion (31b) and may be positioned facing or opposite to each other.

[0090] For example, the holder (30) may include a first opening exposing an incident surface (8A) of the optical member (40) and a second opening exposing an exit surface (8B) of the optical member (40). For example, the first opening may be disposed on an upper side of the holder (30), and the second opening may be disposed on a side (front outer surface, 31a) of the holder (30) facing a lens assembly (e.g., 311) of the first actuator (310). The exit surface (8B) of the optical member (40) mounted on the holder (30) may be disposed to face the lens assembly (e.g., 311) of the first actuator (310).

[0091] Referring to FIGS. 6A and 6B, the upper surface (18) of the holder (30) may include a first surface (18A) and a second surface (18B) having a step in a second direction (e.g., X-axis direction) from the first surface (18A). The first surface (18A) may be positioned adjacent to or in contact with the rear outer surface (31b) of the holder (30), and the second surface (18B) may be positioned adjacent to or in contact with the first side (31a) of the holder (30). The second surface (18B) may be positioned lower than the first surface (18A). For example, the second surface (18B) may be positioned closer to the lower surface (19) of the holder (30) than the first surface (18A).

[0092] Since the second surface (18B) has a step with the first surface (18A), when the holder (30) tilts or rotates by a preset angle in the second direction (e.g., in the X-axis direction), spatial interference between the holder (30) and the first housing (50) can be prevented.

[0093] For example, at least one stopper (38) may be formed on the upper surface (e.g., the second surface (18B)) of the holder (30). The stopper (38) may be a projection or a protrusion protruding upward from the upper surface (e.g., the second surface (18B)) of the holder (30). For example, the stopper (38) may be formed on the upper surface of each of the first and second sides of the holder (30). The tilt or rotation of the holder (30) in the second direction may be restricted by the stopper (38). For example, the height of the upper surface of the stopper (38) may be lower than or equal to the height of the first surface (18A).

[0094] The holder (30) may include sides (or outer surfaces) (31c, 31d) that are positioned facing each other or opposite each other. For example, the mounting portion (104) may be positioned between two sides (31c, 31d) of the holder (30). For example, the two sides (31c, 31d) may be positioned opposite each other or facing each other in a third direction (e.g., the Y-axis direction).

[0095] Each of the third and fourth sides (31c, 31d) of the holder (30) may include a first outer side (19A) and a second outer side (19B) having a step in a third direction (e.g., Y-axis direction) from the first outer side (19A). The first outer side (19A) may be positioned adjacent to or in contact with the second side (31b) of the holder (30), and the second outer side (19B) may be positioned adjacent to or in contact with the first side (31a) of the holder (30). The inner side of the holder (30) may be positioned closer to the first outer side (19A) than to the second outer side (19B) of the holder (30).

[0096] Since the second outer surface (19B) of the holder (30) has a step with the first outer surface (19A), when the holder (30) tilts or rotates by a preset angle in the third direction (e.g., the Y-axis direction), spatial interference between the holder (30) and the first housing (50) can be prevented.

[0097] For example, at least one stopper (39A) may be formed on the third and fourth sides (e.g., the second outer side surface (19B)) of the holder (30). The stopper (39A) may be a projection or a protrusion protruding from the outer side surface (e.g., the second outer side surface (19B)) of each of the third and fourth sides (31c, 31d) of the holder (30). The tilt or rotation of the holder (30) in the third direction may be restricted by the stopper (39A). For example, the protruding height of the stopper (39A) with respect to the second outer side surface (19B) may be smaller than or equal to the step difference between the first outer side surface (19A) and the second outer side surface (19B).

[0098] Referring to FIG. 6c, the lower surface (17) of the holder (30) may include a first surface (17A) and a second surface (17B) having a step in a second direction (e.g., X-axis direction) from the first surface (17A). The first surface (17A) may be positioned adjacent to or in contact with the first side (31a) of the holder (30), and the second surface (17B) may be positioned adjacent to or in contact with the second side (31b) of the holder (30). The first surface (17A) may be positioned lower than the second surface (17B). For example, the upper surface (18) of the holder (30) may be positioned closer to the second surface (17B) than to the first surface (17A).

[0099] Since the second surface (17B) of the lower surface (17) of the holder (30) has a step with the first surface (17A), when the holder (30) tilts or rotates by a preset angle in the second direction (e.g., in the X-axis direction), spatial interference between the holder (30) and the second OIS coil (230C) can be prevented.

[0100] For example, at least one stopper (41) may be formed on the lower surface (e.g., the second surface (17B)) of the holder (30). The stopper (41) may be a projection or a protrusion protruding downward from the lower surface (e.g., the first surface (17A)) of the holder (30). The tilt or rotation of the holder (30) in the second direction may be limited by the stopper (41). For example, the protruding length of the stopper (38) with respect to the second surface (17B) may be smaller than or equal to the step between the first surface (17A) and the second surface (17B) of the lower surface (17) of the holder (30). In another embodiment, the stopper may be located on the second surface (17B) of the lower surface of the holder (30).

[0101] The holder (30) may include a first mounting groove (16A, see FIG. 5) for placing or settling a first OIS magnet (31) (or “first magnet unit”) and a second mounting groove (16B, see FIG. 6c) for placing or settling a second OIS magnet (32) (or “second magnet unit”).

[0102] For example, the first settling groove (16A) may be formed on the outer surface (e.g., the first outer surface (19A)) of each of the third and fourth side portions (31c, 31d) of the holder (30). For example, the first settling groove (16A) may be in the form of a recessed groove from the first outer surface (19A) of each of the third and fourth side portions (31c, 31d) of the holder (30).

[0103] For example, the second mounting groove (16B) may be formed on the lower surface (17) (e.g., the first surface (17A)) of the holder (30). For example, the second mounting groove (16B) may be in the form of a groove sunken from the lower surface (17) (e.g., the first surface (17A)) of the holder (30).

[0104] Referring to FIG. 6b, the second side (31b) of the holder (30) may include a first side (21a), a second side (21b) adjacent to or in contact with a third side (31c), and a third side (21c) adjacent to or in contact with a fourth side (31d).

[0105] When viewed from the rear, the first side (21a) can be placed in the center, the second side (21b) can be placed on the left side of the first side (21a), and the third side (21c) can be placed on the right side of the first side (21a).

[0106] Each of the second surface (21b) and the third surface (21c) may have a step with respect to the first surface (21a) in the first direction (e.g., the Z-axis direction). For example, the inner surface of the holder (30) may be positioned closer to the first surface (21a) than each of the second surface (21b) and the third surface (21c). For example, the second surface (21b) and the third surface (21c) may be positioned on the same plane. Alternatively, for example, the step between the first surface (21a) and the second surface (21b) may be the same as the step between the first surface (21a) and the third surface (21c), but is not limited thereto, and in other embodiments, the two may be different from each other.

[0107] For example, a groove (106) for seating or accommodating a mover plate (61) may be formed in the second side (31b) of the holder (30). For example, the groove (106) may be positioned in the center of the second side (31b) and may be recessed from the outer surface of the second side (31b).

[0108] The holder (30) may include a coupling groove (105A, 105B) for coupling with the support (64). For example, the coupling groove (105A, 105B) may be formed on the outer surface of the second side (31b) of the holder (30).

[0109] For example, the holder (30) may include a first coupling groove (105A) formed on the second surface (21b) of the outer surface of the second side (31b), and a second coupling groove (105B) formed on the third surface (21c).

[0110] For example, at least one groove (2A) may be formed on at least one of the side surfaces and the bottom surfaces of each of the first and second coupling grooves (105A, 105B). For example, at least one groove (2A) of the holder (30) may correspond to at least one protrusion (7A) of the support portion (64) or may be formed at a position corresponding to at least one protrusion (7A). At least one groove (2A) of the holder (30) may be coupled with at least one protrusion (7A) of the support portion (64).

[0111] The holder (30) may include at least one stopper (not shown) formed on the outer surface (31b) of the second side (31b). For example, the stopper may be in the form of a protrusion or projection protruding from each of the second surface (21b) and the third surface (21c) of the second side (31b).

[0112] The holder (30) may include a mounting portion (37) (or receiving portion) for placing or receiving a magnetic body (62). The mounting portion (37) may be a recess or groove.

[0113] For example, the mounting portion (37) may be positioned on the second side of the holder (30). For example, the mounting portion (37) may be positioned on the second side (31b) of the holder (30). For example, the mounting portion (37) may be formed on the first surface (21a) of the holder (30).

[0114] The first housing (50) may be placed within the cover member (300). For example, an adhesive or shield member may be placed between the first housing (50) and the cover member (300), and the first housing (50) may be coupled or fixed to the cover member (300).

[0115] The holder (30) can be placed within the first housing (50). The first housing (50) can accommodate the holder (30) therein and expose the incident surface (8A) and the output surface (8B) of the optical member (40) placed in the holder (30).

[0116] Referring to FIGS. 9A to 9D , for example, the first housing (50) may include a first opening (53A) (or first hole) for exposing the incident surface (8A) of the optical member (40). In addition, the first housing (50) may include a second opening (53B) (or second hole) for exposing the exit surface (8B) of the optical member (40).

[0117] The first housing (50) may include an upper portion (27A), a lower portion (27B), and a side portion positioned between the upper portion (27A) and the lower portion (27). For example, the side portion of the first housing (50) may include a plurality of side portions (28A to 28D). The upper portion (27A) and the lower portion (27B) of the first housing (50) may face each other in a second direction (e.g., in the X-axis direction) or may be positioned opposite to each other.

[0118] For example, the first housing (50) may include a first side (28A), a second side (28B), a third side (28C), and a fourth side (28D).

[0119] For example, the first side (28A) of the first housing (50) may be arranged to face or be opposite the lens assembly (e.g., 311) of the first actuator (310). The first side (28A) may face the exit surface (8B) of the optical member (40). The first opening (53A) may be formed in the upper portion (27A), and the second opening (53B) may be formed in the first side (28A).

[0120] The second side (28B) may face the first side (28A) in the first direction or may be positioned opposite the first side (28A). The third side (28C) and the fourth side (28D) may be positioned between the first side (28A) and the second side (28D) and may face or be positioned opposite to each other in the third direction. For example, the third side (28C) may connect one end of the first side (28A) and one end of the second side (28B), and the fourth side (28D) may connect the other end of the first side (28A) and the other end of the second side (28B).

[0121] For example, the first housing (50) may include a first hole (54A) formed in the third side (28C) for mounting or arranging the first OIS coil unit (230A), a second hole (54B) formed in the fourth side for mounting or arranging the second OIS coil unit (230B), and a third hole (54C) formed in the lower part (27B) for mounting or arranging the third OIS coil unit (230C). For example, each of the first to third holes (54A to 54C) is in the form of a through hole, but is not limited thereto, and may be in the form of a groove in other embodiments.

[0122] Additionally, a groove (56) (or through hole) for placing or settling a second driver (260) may be formed in the fourth side (28D) (or third side (28C)) of the first housing (50). For example, the groove (56) may be formed spaced apart from the second hole (54B).

[0123] The first housing (50) may include at least one engaging protrusion (51) formed on at least one of the third side (28C) and the fourth side (28D). For example, the engaging protrusion (51) may protrude from the outer surface of at least one of the third side (28C) and the fourth side (28D). In addition, the first housing (50) may include at least one engaging protrusion (52A) formed on the first side (28A). For example, the engaging protrusion (52A) may protrude from the outer surface of the first side (28A).

[0124] Additionally, the first housing (50) may include at least one coupling protrusion (52B) formed on the lower portion (28B). For example, the coupling protrusion (52B) may be formed to protrude from the outer surface of the lower portion (28B).

[0125] A guide protrusion (59A) for guiding a first circuit board (250A) may be formed on at least one of the upper and lower portions of the third side portion (28C) of the first housing (50). In addition, a guide protrusion (59B) for guiding a second circuit board (250B) may be formed on at least one of the upper and lower portions of the fourth side portion (28D) of the first housing (50).

[0126] Referring to FIG. 9d, the first housing (50) may include a groove (58) corresponding to the front protrusion (61C) of the driving plate (61).

[0127] For example, the second side (28B) of the first housing (50) may include at least two grooves (58A, 58B) corresponding to at least two front protrusions (61C1, 61C2) of the drive plate (61). For example, the at least two grooves (58A, 58B) of the first housing (50) may be arranged to be spaced apart in the second direction (X-axis direction). In another embodiment, the at least two grooves of the first housing (50) may be arranged to be spaced apart in the third direction (Y-axis direction).

[0128] For example, the first groove (58A) may include a bottom surface (1W) and a plurality of side surfaces (1A to 1D). The area of ​​at least one of the plurality of side surfaces (1A to 1D) of the first groove (58A) may be different from the area of ​​at least another of the plurality of side surfaces (1A to 1D) of the first groove (58A).

[0129] For example, two side surfaces (1C, 1D) of the first groove (58A) facing each other in the second direction may have a symmetrical shape, and the areas of the two side surfaces (1C, 1D) may be the same. In addition, two side surfaces (1A, 1B) of the first groove (58A) facing each other in the third direction may have a symmetrical shape, and the areas of the two side surfaces (1A, 1B) may be the same.

[0130] The first area of ​​each of the side surfaces (1C, 1D) of the first groove (58A) facing in the second direction may be different from the second area of ​​each of the side surfaces (1A, 1D) of the first groove (58A) facing in the third direction. For example, the first area may be smaller than the second area. In another embodiment, the first area may be larger than the second area. For example, the bottom surface of the first groove (58A) may be rectangular or oval, but is not limited thereto.

[0131] The second groove (58B) may include a bottom surface and a plurality of side surfaces. Each of the plurality of side surfaces of the second groove (58B) may have the same shape. For example, the areas of the plurality of side surfaces of the second groove (36B) may be the same. The plurality of side surfaces of the second groove (36B) may be symmetrical with respect to each other in the second direction and the third direction. For example, the bottom surface of the second groove (36B) may be square or circular, but is not limited thereto.

[0132] In FIG. 9d, the number of side faces of each of the first and second grooves (58A, 58B) is four, but in other embodiments, it may be three or five or more.

[0133] Manufacturing tolerances may occur with respect to the first and second grooves of the first housing (50) and / or the front projections of the drive plate (61). However, if both the first and second grooves of the housing (50) have the shape of the second groove (58B) illustrated in FIG. 9d, the front projections (61C1, 61C2) of the drive plate (61) may not be properly or stably coupled to the first and second grooves of the first housing (50) due to the manufacturing tolerances.

[0134] In the embodiment, by making the shape of the first groove (58A) of the first housing (50) different from that of the second groove (58B), the coupling margin between the front protrusions (61C1, 61C2) of the driving plate (61) and the first and second grooves (58A, 58B) of the first housing (50) can be increased. That is, even if the above-described manufacturing tolerance occurs, the front protrusions (61C1, 61C2) of the driving plate (61) can be suitably or stably coupled to the first and second grooves (58A, 58B) of the first housing (50) by the first groove (58A), and stable OIS operation can be enabled.

[0135] However, in other embodiments, the first groove and the second groove of the first housing (50) may have the same shape. For example, in other embodiments, each of the first groove and the second groove of the first housing (50) may have the shape of the first groove (58A) or the second groove (58B) of FIG. 9d.

[0136] The first housing (50) may include protrusions or steps (not shown) formed around at least two grooves (58A, 58B). A lubricant may be placed between the front projections (61C1, 61C2) and the grooves (58A, 58B) of the first housing (50) to reduce friction, and the protrusions (or steps) of the first housing (50) formed around the first groove (58A) and the second groove (58B) may prevent the lubricant from overflowing.

[0137] For example, the first housing (50) may include a protrusion (57) that protrudes from the inner surface of the second side (28B) toward the first side (28A). In other embodiments, the protrusion (57) may not be provided.

[0138] The first housing (50) may include a portion (or first portion) or area (or first area) disposed between the magnetic body (63) and the driving plate (61). For example, the first portion of the first housing (50) disposed between the magnetic body (63) and the driving plate (61) may be a portion (or an area) of the second side (28B) of the first housing (50). For example, the protrusion (57) may be disposed or formed in the first portion of the first housing (50). At least a portion of the front protrusion (61C) of the driving plate (61) may be disposed in the first portion of the first housing (50), and the rear protrusion (61B) of the driving plate (61) may be disposed in the support. For example, the front protrusion (61C) of the driving plate (61) can protrude toward the first part of the first housing (50), and at least a part of the front protrusion (61C) can come into contact with the first part of the first housing (50), and the rear protrusion (61B) of the driving plate (61) can come into contact with the support.

[0139] The first housing (50) may include a receiving portion (44A) for receiving or placing a magnetic body (63). The receiving portion (44A) may be in the form of a groove or hole. For example, the receiving portion (44A) may be formed in the first portion of the first housing (50).

[0140] The receiving portion (44A) may be disposed on the second side (28B) of the first housing (50). The receiving portion (44A) may be disposed on the inner surface of the second side (28B) of the first housing (50). For example, the receiving portion (44A) may be disposed on or formed in the protrusion (57) of the first housing (50). For example, the receiving portion (44A) may be disposed on or formed on the inner surface or front surface of the protrusion (57) of the first housing (50). For example, the receiving portion (44A) may be located on the opposite side of the grooves (58A, 58B).

[0141] In Fig. 9d, when the first housing (50) is viewed from the rear, the first groove (58A) is located on the upper side and the second groove (58B) is located on the lower side, but this is not limited to this, and in other embodiments, the second groove (58B) may be located on the upper side of the first groove (58A).

[0142] The first housing (50) may include a mounting portion (79) for placing at least a portion of the driving plate (61). The mounting portion (79) may be located on the second side (28B) of the first housing (50). The mounting portion (79) may be a groove that is recessed from the outer surface of the second side (28B) of the first housing (50). For example, the mounting portion (29) may include a bottom surface (79A) having a step in the first direction from the outer surface of the second side (28B) of the first housing (50), and a side surface (or side wall (79B)) located between the bottom surface (79A) and the outer surface of the second side (28B) of the first housing (50).

[0143] For example, the grooves (58A, 58B) may be arranged on the bottom surface (79A) of the mounting portion (79) or formed on the bottom surface (79A). The mounting portion (79) may serve to prevent the driving plate (61) from being detached from the first housing (50) and to stably support the holder (30) by the driving plate (61). In addition, since the driving plate (61) is arranged within the mounting portion (79), the size of the camera device (200) in the first direction (optical axis direction) may be reduced. In another embodiment, the first housing (50) may not have the mounting portion (79).

[0144] The first housing (50) may include an opening (55) for at least a portion of the support (64) to pass through. For example, the opening (55) may be formed in the second side (28B) of the first housing (50). For example, the opening (55) may be a through hole penetrating the second side (28B). For example, at least one through hole may be formed in the second side (28B) of the first housing (50). For example, the opening (55) may include a first through hole (55A) and a second through hole (55B) formed in the second side (28B) of the first housing (50).

[0145] As illustrated in FIG. 9c, when viewed from the rear of the first housing (50), the first through hole (55A) may be located on one side (e.g., the right side) of the protrusion (57) of the first housing (50), and the second through hole (55B) may be located on the other side (e.g., the left side) of the protrusion (57). A part of the support portion (64) may pass through the first through hole (55A) of the first housing (50), and another part of the support portion (64) may pass through the second through hole (55B) of the first housing (50).

[0146] Next, the support joint (60) will be described.

[0147] The support coupling part (60) can support the OIS moving part with respect to the first housing (50). The support coupling part (60) can be arranged between the OIS moving part and the first housing (50). The support coupling part (60) can include a mover plate (61) arranged between the first housing (50) and the support part (64).

[0148] The driving plate (61) may be expressed as a “mover”, “mover plate”, “driving plate”, “plate”, “rotary plate”, “moving plate”, “support plate”, “tilting guide”, or “tilting plate”.

[0149] The driving plate (61) may have a first axis for tilting the OIS moving part. In addition, the driving plate (61) may have a second axis for tilting the OIS moving part. The driving plate (61) may support the OIS moving part with respect to the fixed part. The driving plate (61) may guide the tilting or movement of the OIS moving part.

[0150] The support coupling portion (60) may include a support portion (64) that is coupled with the holder (30) and supports the drive plate (61). At least a portion of the support portion (64) may pass through at least a portion of the first housing (50) to be coupled with the holder (30). At least a portion of the support portion (64) may pass through the second side (28B) of the first housing (50) to be coupled with the holder (30).

[0151] The driving plate (61) may be disposed between the first housing (50) and the support member (64). At least a portion of the driving plate (61) may be in contact with or in close contact with the first housing (50), and at least another portion of the driving plate (61) may be in contact with or in close contact with the support member (64).

[0152] The support (64) may be alternatively expressed as a “joint”, a “holder rigid”, a “mover rigid”, or a “holding rigid”.

[0153] For example, the support (64) may be formed of an injection molded material, plastic, or resin material, or in another embodiment, the support (64) may be formed of a metal material or a metal plate. Alternatively, the support (64) may be formed of a heat dissipation member. The support (64) may have a polyhedral shape.

[0154] Referring to FIGS. 7, 8A, 8B, and 10A, the support member (64) may include a groove (36) corresponding to a rear protrusion (61B) of the drive plate (61). For example, the support member (64) may include at least two grooves (36A, 36B) corresponding to at least two rear protrusions (61B1, 61B2) of the drive plate (61). For example, at least two grooves (36A, 36B) of the support member (64) may be arranged spaced apart in the third direction (Y-axis direction). In another embodiment, at least two grooves of the support member (64) may be arranged spaced apart in the second direction (X-axis direction).

[0155] The first groove (36A) of the support member (64) may include a bottom surface (1M) and a plurality of side surfaces (1E to 1H). In addition, the second groove (36B) may include a bottom surface and a plurality of side surfaces.

[0156] The description of the first and second grooves (58A, 58B) of the first housing (50) can be applied or analogized to the first and second grooves (36A, 36B) of the support. A protrusion (or step) may be formed around the grooves (36A, 36B) of the support (64). A lubricant may be placed between the rear projections (61B1, 61B2) and the grooves (36A, 36B) of the support (64) to reduce friction, and the protrusion (or step) of the support (64) formed around the first groove (36A) and the second groove (36B) can prevent the lubricant from overflowing.

[0157] A portion of the support (64) may pass through the first housing (50) and be coupled to the holder (30). For example, a portion of the support (64) may pass through the first housing (50) and be coupled to the second side of the holder (30).

[0158] The support member (64) may include a body (93) and at least one extension member (94a, 94b) (or protrusion) extending from the body (93). For example, at least one extension member (94a, 94b) may pass through an opening (55) of the first housing (50) and be coupled to the holder (30).

[0159] For example, the support member (64) may include a body (93) facing the driving plate (61), a first extension member (94a) extending from one side of the body (93) and passing through a first through-hole (55A) of the first housing (50) to be coupled with the holder (30), and a second extension member (94b) extending from the other side of the body (93) and passing through a second through-hole (55B) of the first housing (50) to be coupled with the holder (30).

[0160] For example, the first extension portion (94a) can be coupled with the first coupling groove (105A) of the holder (30), and the second extension portion (94b) can be coupled with the second coupling groove (105B) of the holder (30). For example, the extension portions (94a, 94b) of the support portion (64) can be coupled with the coupling grooves (105A, 105B) of the holder (30) by an adhesive. For example, the first extension portion (94a) and the second extension portion (94b) can be symmetrical left and right with respect to the body (93). In another embodiment, the first extension portion (94a) and the second extension portion (94b) can be asymmetrical with respect to the body (93).

[0161] The extension portion (94a, 94b) may include at least one protrusion (7A) for engaging with at least one groove (2A) of the holder (30). In other embodiments, the extension portion (94a, 94b) may have a groove formed instead of the protrusion (7A), and the holder (30) may have a protrusion formed instead of the groove (2A).

[0162] At least two grooves (36A, 36B) of the support member (64) may be arranged or formed in the body (93) of the support member (64). For example, at least two grooves (36A, 36B) may be formed on one surface of the body (93) facing the driving plate (61).

[0163] The support (64) is formed to be combined with the holder (30), but may also be expressed as a part of the holder (30). In another embodiment, the support (64) may be expressed as an extension extending from the holder (30). In another embodiment, the support (64) may be formed integrally with the holder (30).

[0164] Referring to FIG. 10A, the driving plate (61) may be disposed between the body (93) of the support (64) and the second side (28B) of the first housing (50). For example, the driving plate (61) may be disposed between the mounting portion (79) of the first housing (50) and the support (64). For example, the driving plate (61) may be disposed between the protrusion (57) and the support (64). For example, the driving plate (61) may be disposed between the support (64) and the magnetic body (63).

[0165] At least a portion of the drive plate (61) may contact, be coupled to, or be in close contact with the first housing (50), and at least another portion of the drive plate (61) may be contacted, be coupled to, or be in close contact with the support member (64).

[0166] For example, at least a portion of the drive plate (61) may contact, be coupled to, or be in close contact with the second side (28B) of the first housing (50), and at least another portion of the drive plate (61) may be in contact with, be coupled to, or be in close contact with the body (93) of the support member (64).

[0167] The driving plate (61) may include a body (61A), a front protrusion (61C) that contacts, engages, or adheres to the first housing (50), and a rear protrusion (61B) that contacts, engages, or adheres to the support (64). For example, the front protrusion (61C) may protrude from a first surface of the body (61A) that faces the first housing (50). The rear protrusion (61B) may protrude from a second surface of the body (61A) that faces the support (64). The front protrusion (61C) and the rear protrusion (61B) may protrude in opposite directions.

[0168] For example, the front projection (61C) of the drive plate (61) may include at least two or more front projections (61C1, 61C2). For example, the rear projection (61B) may include at least two or more rear projections (61B1, 61B2).

[0169] For example, the front protrusions (61C1, 61C2) may be arranged to be spaced apart in the first axis direction or the second direction (e.g., the X-axis direction). Each of the front protrusions (61C1, 61C2) may be arranged in a corresponding one of the first and second grooves (58A, 58B) of the first housing (50). Each of the front protrusions (61C1, 61C2) may be coupled to or in contact with a corresponding one of the first and second grooves (58A, 58B) of the first housing (50). The front protrusions (61C1, 61C2) may form a first axis for tilting the OIS moving part.

[0170] For example, the rear protrusions (61B1, 61B2) may be arranged spaced apart in the second axis direction or the third direction (e.g., the Y-axis direction). Each of the rear protrusions (61B1, 61B2) may be arranged in a corresponding one of the first and second grooves (36A, 36B) of the support member (64). Each of the rear protrusions (61B1, 61B2) may be coupled to or in contact with a corresponding one of the first and second grooves (36A, 36B) of the support member (64). The rear protrusions (61C1, 61C2) may form a second axis for tilting the OIS moving part.

[0171] In another embodiment, the front protrusions of the drive plate (61) may be arranged spaced apart in the second axis direction or the third direction (e.g., the Y-axis direction), and in another embodiment, the rear protrusions of the drive plate (61) may be arranged spaced apart in the second axis direction or the second direction.

[0172] For example, each of the front protrusion (61C) and the rear protrusion (61B) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape.

[0173] In another embodiment, instead of the front projections, the front surface of the drive plate may be formed with front grooves spaced apart in the first axial direction (or the second axial direction). Also, instead of the first and second grooves (58A, 58B), the first housing (50) may be formed with projections spaced apart in the second axial direction (or the first axial direction) for engaging with the front grooves of the drive plate.

[0174] Additionally, in another embodiment, instead of the rear projection of the drive plate, a rear groove may be formed on the rear of the drive plate, and instead of the first and second grooves (36A, 36B), the support member (64) may be formed with projections for engaging with the rear grooves of the drive plate.

[0175] In another embodiment, the drive plate may have front grooves formed instead of front protrusions, and the drive plate may have rear grooves formed instead of rear protrusions, and the camera device (200) may include first ball members (or first balls) disposed between the grooves (58A, 58B) of the first housing (50) and the front grooves of the drive plate, and second ball members (or second balls) disposed between the rear grooves of the drive plate and the grooves (36A, 36B) of the support (64).

[0176] For example, the driving plate (61) may be made of an injection-molded material such as plastic or resin. In another embodiment, the driving plate (61) may be made of a metal, for example, SUS material. In addition, the driving plate (61) may be a non-magnetic material. In another embodiment, the driving plate (61) may be a magnetic material.

[0177] The support coupling part (60) may include a magnetic body (62) placed on the OIS moving part and a magnetic body (63) placed on the fixed part. For example, the magnetic body (62) may be placed on or coupled to the holder (30), and the magnetic body (63) may be placed on or coupled to the first housing (50).

[0178] Referring to FIGS. 9A and 9C, the magnetic body (63) may be placed on the second side (28B) of the first housing (50). For example, the magnetic body (63) may be placed on the protrusion (57) of the first housing (50). For example, the magnetic body (63) may be placed within the groove (44A) of the protrusion (57) of the first housing (50). For example, the magnetic body (63) may be coupled to the groove (44a) of the first housing (50) by an adhesive.

[0179] Referring to FIGS. 12 and 13, the magnetic bodies (62) and the magnetic bodies (63) may be arranged to face each other or overlap each other in the first direction. A repulsive force may be applied between the magnetic bodies (62) and the magnetic bodies (63). A repulsive force may be applied between the magnetic bodies (62) and the magnetic bodies (63) in the direction of the optical axis (or the first direction).

[0180] Each of the magnetic bodies (62, 63) may be made of a material having magnetism. For example, each of the magnetic bodies (33) may be a magnet including a north pole and a south pole.

[0181] For example, the magnetic body (62) may include a first magnet. For example, the magnetic body (63) may include a second magnet that exerts a repulsive force on the first magnet.

[0182] Additionally, the camera device (200) may include a first yoke (not shown) that is disposed or coupled to the holder (30) and corresponds to, faces, or overlaps the magnetic body (62). The first yoke may be disposed within the mounting portion (37) of the holder (30). For example, the first yoke may be disposed between the bottom surface of the mounting portion (37) and the magnetic body (62).

[0183] Additionally, the camera device (200) may include a second yoke (not shown) disposed or coupled to the first housing (50) and corresponding to, opposite to, or overlapping with the magnetic body (63). For example, the second yoke may be disposed within the receiving portion (44A) of the first housing (50). For example, the second yoke may be disposed between the bottom surface of the receiving portion (44A) of the first housing (50) and the magnetic body (63).

[0184] The first yoke and the second yoke can serve to increase the magnetic force (e.g., repulsive force) generated between the magnetic body (62) and the magnetic body (63).

[0185] For example, the facing surfaces of the magnetic body (62) and the magnetic body (63) may have the same polarity (N pole or S pole).

[0186] The magnetic body (62) and the magnetic body (63) can be placed between the driving plate (61) and the optical member (40). The driving plate (61) can be placed between the first housing (50) and the support (64). For example, the driving plate (61) can be placed between the second side (28B) of the first housing (50) and the support (64). The driving plate (61) can be spaced apart from the holder (30).

[0187] The optical member (40) may be positioned closer to the magnetic body (62) than the driving plate (61). In addition, the optical member (40) may be positioned closer to the magnetic body (63) than the driving plate (61). In addition, the optical member (40) may be positioned closer to the magnetic body (62) than the magnetic body (63).

[0188] In a direction perpendicular to the first direction, the driving plate (61) may not overlap with the holder (30). For example, in a second direction, the driving plate (61) may not overlap with the holder (30). In a direction perpendicular to the first direction, the driving plate (61) may not overlap with the optical member (40). For example, in a second direction, the driving plate (61) may not overlap with the optical member (40).

[0189] At least a portion of the driving plate (61) may overlap the support portion (64) in a direction perpendicular to the first direction. For example, at least a portion of the driving plate (61) may overlap the support portion (64) in the second direction or the third direction.

[0190] The distance between the optical member (40) (or holder (30)) and the driving plate (61) may be greater than the distance between the optical member (40) (or holder (30)) and the magnetic body (63) (or magnetic body (62)). For example, the distance in the first direction between the optical member (40) (or holder (30)) and the driving plate (61) may be greater than the distance in the first direction between the optical member (40) (or holder (30)) and the magnetic body (63) (or magnetic body (62)).

[0191] At least a portion of the drive plate (61) may be positioned on the outside of the first housing (50). For example, at least a portion of the drive plate (61) may be positioned on the outside of the second side (28B) of the first housing (50).

[0192] The magnetic body (62) can be placed on the second side (31b) of the holder (30), and the magnetic body (63) can be placed on the third side (28B) of the first housing (50). The magnetic body (63) can be positioned between the magnetic body (63) and the driving plate (61).

[0193] The magnetic bodies (62, 63) may be positioned on the inside of the first housing (50), and at least a portion of the driving plate (61) may be positioned on the outside of the first housing (50). The magnetic bodies (62, 63) may be positioned closer to the holder (30) than to the driving plate (61).

[0194] The driving plate (61) can be pressed against the support (64) and / or the first housing (50) by the repulsive force between the magnetic bodies (62, 63), and can be brought into close contact with the support (64) and / or the first housing (50).

[0195] The support member (64) (or body (93)) can press the driving plate (61) by the repulsive force acting between the magnetic body (62) and the magnetic body (63). The second side (28B) (or mounting member (79)) of the first housing (50) can press the driving plate (61) by the repulsive force acting between the magnetic body (62) and the magnetic body (63). As a result, the front protrusion (61C) and the rear protrusion (61B) of the driving plate (61) can be pressed against the groove (58) of the first housing (50) and the groove (36) of the support member (64).

[0196] In the embodiment, since the magnetic force (e.g., repulsive force) between the magnetic body (62) and the magnetic body (63) is large, the driving plate (61) can stably support the holder (30), and thus, stable OIS operation can be performed.

[0197] Referring to Fig. 12, the length of the magnetic body (62) in the second direction (X-axis direction) may be smaller than the length of the magnetic body (63) in the second direction. Also, referring to Fig. 13, the length of the magnetic body (62) in the third direction (Y-axis direction) may be smaller than the length of the magnetic body (63) in the third direction. This is to reduce the weight of the moving part and reduce the driving current or power consumption required for driving the OIS by reducing the size of the magnetic body (62) arranged in the moving part.

[0198] In another embodiment, the length of the magnetic body (62) in the second direction may be equal to or greater than the length of the magnetic body (63) in the second direction. Also, in another embodiment, the length of the magnetic body (62) in the third direction may be equal to or greater than the length of the magnetic body (63) in the third direction.

[0199] For example, the first surface of the magnetic body (63) and the first surface of the magnetic body (62) may face each other in the optical axis direction. And the area of ​​the first surface of the magnetic body (62) may be smaller than the area of ​​the first surface of the magnetic body (63). In another embodiment, the area of ​​the first surface of the magnetic body (62) may be equal to or larger than the area of ​​the first surface of the magnetic body (63).

[0200] Next, the second driving unit (70) will be described.

[0201] The second driving unit (70) tilts the holder (30) in the second or third direction or rotates it by a preset angle.

[0202] The second driving unit (70) may include an OIS magnet (31) and an OIS coil (230). The OIS magnet may be replaced with a “magnet” or a “magnet unit,” and the OIS coil may be replaced with a “coil” or a “coil unit.” In addition, the second driving unit (70) may include an OIS position sensor unit (240) and a first substrate unit (250).

[0203] The OIS magnet (31) can be placed on the holder (30) or combined with the holder (30). For example, the OIS magnet (31) can include a first OIS magnet (31A, 31B) and a second OIS magnet (32).

[0204] For example, the first OIS magnet may include a first magnet unit (31A) arranged on a third side (31c) of the holder (30) and a second magnet unit (31B) arranged on a fourth side (31d) of the holder (30). For example, the first magnet unit (31A) may face or overlap the second magnet unit (31B) in the third direction. For example, the first magnet unit (31A) may be arranged in a first mounting groove (16A) of the third side (31c) of the holder (30), and the second magnet unit (31B) may be arranged in a first mounting groove (16A) of the fourth side (31d) of the holder (30).

[0205] The second OIS magnet may include a third magnet unit (32) arranged on the lower surface (17) of the holder (30). The third magnet unit (32) may be arranged within the second mounting groove (16B) of the holder (30).

[0206] Each of the first to third magnet units (31A, 31B, 32) may be a unipolar magnet having one N pole and one S pole, but is not limited thereto, and in another embodiment may be a bipolar magnet having two N poles and two S poles. In another embodiment, at least one of the first to third magnet units (31A, 31B, 32) may be a unipolar magnet, and the rest may be bipolar magnets.

[0207] The OIS coil (230) may be disposed in the first housing (50). For example, the OIS coil may be disposed corresponding to or opposite the OIS magnet (31). For example, the OIS coil (230) may include a first OIS coil (230A, 230B) corresponding to, opposite to, or overlapping the first OIS magnet (31A, 31B) in a third direction, and a second OIS coil (230C) corresponding to, opposite to, or overlapping the second OIS magnet (32) in a second direction.

[0208] For example, the first OIS coil may include a first OIS coil unit (230A) corresponding to, opposite to, or overlapping the first magnet unit (31A) in a third direction, and a second OIS coil unit (230B) corresponding to, opposite to, or overlapping the second magnet unit (31B) in the third direction. In another embodiment, the first OIS magnet may include one magnet unit (e.g., one of 31A and 31B), and the first OIS coil may include one coil unit (e.g., one of 230A and 230B).

[0209] For example, the second OIS coil may include a third OIS coil unit (230C) corresponding to, opposite to, or overlapping with the third magnet unit (32) in the second direction.

[0210] For example, the first OIS coil unit (230A) may be placed on the third side (28C) of the first housing (50) (e.g., the first hole (34A)), the second OIS coil unit (230B) may be placed on the fourth side (28D) of the first housing (50) (e.g., the second hole (54B)), and the third OIS coil unit (230C) may be placed on the lower part (28B) of the first housing (50) (e.g., the third hole (54C)).

[0211] For example, the first OIS coil unit (230A) may have a closed curve or ring shape including a hollow or hole. The first OIS coil unit (230A) may be implemented in the form of a coil ring wound clockwise or counterclockwise around a third axis parallel to the third direction.

[0212] The second OIS coil unit (230B) may have a closed curve or ring shape including a hollow or hole. The second OIS coil unit (230B) may be implemented in the form of a coil ring wound clockwise or counterclockwise around a third axis parallel to the third direction.

[0213] The third OIS coil unit (230C) may have a closed curve or ring shape including a hollow or hole. The third OIS coil unit (230C) may be implemented in the form of a coil ring wound clockwise or counterclockwise around a second axis parallel to the second direction.

[0214] Referring to Fig. 11, an electromagnetic force (F21, F22) may be generated by the interaction between the first OIS magnet (31A, 31B) and the first OIS coil (230A, 230B). That is, a first electromagnetic force (F21) may be generated by the interaction between the first magnet unit (31A) and the first OIS coil unit (230A), and a second electromagnetic force (F22) may be generated by the interaction between the second magnet unit (31B) and the second OIS coil unit (230B).

[0215] Additionally, an electromagnetic force (F1) can be generated by the interaction between the second OIS magnet (32) and the third OIS coil unit (230C).

[0216] The OIS moving part (e.g., holder (30)) can be tilted along a second axis (e.g., X-axis) by electromagnetic force (F21, F22). Here, the second axis (X-axis) tilting means that the OIS moving part is tilted based on the second axis (X-axis) or the OIS moving part is rotated by a preset angle with the second axis (X-axis) as the rotation axis.

[0217] The OIS moving part can be tilted along a third axis (e.g., Y-axis) by an electromagnetic force (F1). Here, the third-axis (Y-axis) tilting means that the OIS moving part is tilted based on the third axis or that the OIS moving part is rotated by a preset angle around the third axis as a rotation axis.

[0218] In addition, the first OIS coil unit (230A) and the second OIS coil unit (230B) can overlap in the third direction (Y-axis direction). The first OIS magnet (31A) and the second OIS magnet (31B) can overlap in the third direction. By this arrangement, the electromagnetic force is applied evenly to the third side (31c) and the fourth side (31d) of the holder (30), so that the X-axis tilt can be performed accurately and precisely.

[0219] In another embodiment, the OIS moving part (e.g., holder (30)) may be tilted about a third axis (e.g., Y axis) by an electromagnetic force due to an interaction between the first OIS magnet (31A, 31B) and the first OIS coil (230A, 230B), and the OIS moving part (e.g., holder (30)) may be tilted about a second axis (e.g., X axis) by an electromagnetic force due to an interaction between the second OIS magnet (32) and the third OIS coil unit (230C).

[0220] The camera device (200) may further include a yoke (33: 33A, 33B, 33C) disposed on the OIS magnet (31, 32).

[0221] For example, the yoke (33) may include a first yoke (33A) disposed in the first magnet unit (31A), a second yoke (33B) disposed in the second magnet unit (31B), and a third yoke (33C) disposed in the third magnet unit (32).

[0222] For example, the first yoke (33A) may be placed in the first mounting groove (16A) of the third side (31c) of the holder (30). For example, the first yoke (33A) may be placed inside the first magnet unit (31A). The second yoke (33B) may be placed in the first mounting groove (16A) of the fourth side (31d) of the holder (30). For example, the second yoke (33B) may be placed inside the second magnet unit (31B). The third yoke (33C) may be placed in the second mounting groove (16B) of the holder (30). The third yoke (33C) may be placed inside the third magnet unit (32). The first yoke (33A) and the second yoke (33B) can increase the electromagnetic force (F21, F22), and the third yoke (33C) can increase the electromagnetic force (F1).

[0223] The first substrate portion (250) may be placed in the first housing (50). For example, the first substrate portion (250) may be coupled to the first housing (50). The first substrate portion (250) may be electrically connected to the OIS coil (230) and may supply a driving signal to the OIS coil (230).

[0224] For example, the first OIS coil unit (230A) and the second OIS coil unit (230B) may be connected in series with each other, and the first substrate portion (250) may provide a first driving signal to the first and second OIS coil units (230A, 230B) that are connected in series. In another embodiment, for example, the first OIS coil unit (230A) and the second OIS coil unit (230B) may not be connected with each other, and the first substrate portion (250) may provide independent driving signals to each of the first OIS coil unit (230A) and the second OIS coil unit (230B).

[0225] Additionally, the first substrate portion (250) can provide a second driving signal to the third OIS coil unit (230C).

In another embodiment, at least one of the first to third circuit boards may not be integrated with the others, and may be electrically connected to each other.

[0228] A hole (251A) may be formed in the first circuit board (250A) to be coupled with a coupling protrusion (51) of the third side (28C) of the first housing (50). In addition, the first circuit board (250A) may include a plurality of terminals (251).

[0231] A hole (251B) may be formed in the second circuit board (250B) to be coupled with a coupling protrusion (51) of the fourth side (28D) of the first housing (50). A hole (251C) may be formed in the third circuit board (250C) to be coupled with a coupling protrusion (52B) of the lower portion (28B) of the first housing (50).

[0233] The first substrate portion (250) may include at least one of a rigid printed circuit board (Rigid PCB), a flexible printed circuit board (Flexible PCB), or a rigid-flexible printed circuit board (RigidFlexible PCB). In addition, the first substrate portion (250) may include a wiring pattern for electrically connecting components arranged on the first to third circuit boards (250A, 250B, 250C) and a plurality of terminals (251).

[0234] The camera device (200) may further include a gyro sensor (82) disposed on the first substrate (250). The gyro sensor (82) may be electrically connected to the first substrate (250). For example, the gyro sensor (82) may be disposed on any one of the first to third circuit substrates (e.g., 250B).

[0235] For example, the gyro sensor (82) may be a 2-axis, 3-axis, or 5-axis gyro sensor or angular velocity sensor.

[0236] The camera device (200) may further include a second driver (260) disposed on the first substrate portion (250). For example, the second driver (260) may be disposed or mounted on the first circuit substrate (250A). For example, the second driver (260) may be disposed on the first housing (50). For example, the second driver (260) may be disposed or mounted on the first surface of the first circuit substrate (250A) of the first housing (50). The second driver (260) may be disposed on any one of the first to third circuit substrates (250A to 250C) (e.g., 250B). The second driver (260) may be electrically connected to the first substrate portion (250).

[0237] The second driver (260) may be electrically connected to the first OIS coil (230A, 230B) and the second OIS coil (230C). In addition, the second driver (260) may be electrically connected to the first OIS position sensor (240A, 240B) and the second OIS position sensor (240C).

[0238] For example, the second driver (260) can provide a driving signal to each of the first OIS position sensor (240A, 240B) and the second OIS position sensor (240C), and can receive a first output signal of the first OIS position sensor (240A, 240B) and a second output signal of the second OIS position sensor (240C).

[0239] Additionally, for example, the second driver (260) can supply a first driving signal (e.g., driving current or driving voltage) to the first OIS coil (230A, 230B) and feedback control the first driving signal using the first output signal of the first OIS position sensor (240A, 240B).

[0240] Additionally, for example, the second driver (260) can supply a second driving signal (e.g., driving current or driving voltage) to the second OIS coil (230C) and feedback control the second driving signal using the second output signal of the second OIS position sensor (240C). For example, the second driver (260) can be expressed as a “driver IC,” an “OIS driver,” a “second driver IC,” or an “OIS control unit.”

[0241] The OIS position sensor unit (240) can detect the position (or displacement) of the OIS moving unit in the second direction and / or the third direction according to the movement of the OIS moving unit. The OIS position sensor (240) can output an output signal according to the result of detecting the position or displacement of the OIS moving unit. The OIS position sensor unit (240) can be expressed as a "second position sensor unit."

[0242] The OIS position sensor unit (240) may include a plurality of position sensors. The OIS position sensor unit (240) may be electrically connected to the first substrate unit (250).

[0243] For example, the OIS position sensor unit (240) may include a first OIS position sensor (240A, 240B) and a second OIS position sensor (240C).

[0244] At least a portion of the first OIS position sensor (240A, 240B) may correspond to, face, or overlap the first OIS magnet (31) in the third direction and may detect the strength of the magnetic field of the first OIS magnet (31).

[0245] For example, the first OIS position sensor may include a first sensor (240A) arranged or mounted on a first circuit board (250A) and a second sensor (240B) arranged or mounted on a first substrate (250-1) of a second circuit board (240B).

[0246] For example, each of the first sensor (240A) and the second sensor (240B) may be a Hall sensor including first and second input terminals and first and second output terminals.

[0247] The first and second input terminals of the first sensor (240A) and the first and second input terminals of the second sensor (240B) can be connected in parallel, and the second driver (260) can supply a driving signal or power to the first and second input terminals of the first and second sensors (240A, 240B) connected in parallel.

[0248] The first and second output terminals of the first sensor (240A) and the first and second output terminals of the second sensor (240B) can be connected in series, and a first output signal can be output from both ends of the series-connected first and second output terminals of the first and second sensors (240A, 240B), and the first output signal can be transmitted to the second driver (260).

[0249] At least a portion of the second OIS position sensor (240C) may correspond to, face, or overlap the second OIS magnet (32) in the second direction and may detect the strength of the magnetic field of the second OIS magnet (32).

[0250] For example, the second OIS position sensor (240C) may include a third sensor (240C1) and a fourth sensor (240C2) arranged or mounted on a third circuit board (250C). The third sensor (240C1) and the fourth sensor (240C2) may face or overlap the third OIS magnet (32) in the second direction. For example, the third sensor (240C1) and the fourth sensor (240C2) may be arranged to be spaced apart from each other in the third direction. For example, the third sensor (240C1) and the fourth sensor (240C) may be arranged within a hollow (or hole) of the third OIS coil unit (230C).

[0251] For example, each of the third sensor (240C1) and the fourth sensor (240C2) may be a Hall sensor including first and second input terminals and first and second output terminals.

[0252] The first and second input terminals of the third sensor (240C1) and the first and second input terminals of the fourth sensor (240B) can be connected in parallel, and the second driver (260) can supply a driving signal or power to the first and second input terminals of the third and fourth sensors (240C1, 240C2) connected in parallel.

[0253] The first and second output terminals of the third sensor (240C1) and the first and second output terminals of the fourth sensor (240C2) can be connected in series, and a second output signal can be output from both ends of the series-connected first and second output terminals of the third and fourth sensors (240C1, 240C2), and the second output signal can be transmitted to the second driver (260).

[0254] In another embodiment, the output terminals of each of the first and second sensors may be unconnected and independent of each other, and may output independent output signals. In addition, the output terminals of each of the third and fourth sensors may be unconnected and independent of each other, and may output independent output signals.

[0255] In another embodiment, the first OIS position sensor may include one position sensor (e.g., a Hall sensor or a driver IC including a Hall sensor) and transmit the output of the one position sensor to the driver (260). The second OIS position sensor may also include one position sensor (e.g., a Hall sensor or a driver IC including a Hall sensor) and transmit the output of the one position sensor to the driver (260).

[0256] In a comparative example, the driving plate (61) may be placed inside the first housing (50) and may be placed between the holder (30) and the first housing (50). In a comparative example, the driving plate that supports and guides tilting may be placed close to the holder (or optical member) that is the target of tilting.

[0257] In the embodiment, since the driving plate (61) is positioned on the outside of the first housing (50), it can be positioned further away from the OIS moving part (e.g., holder (30) (or optical member (40))) than in the comparative example. That is, the driving plate (61) can be positioned further away from the object (holder (30) or optical member (40)) that needs to be tilted for image stabilization.

[0258] In the embodiment, the driving plate is positioned far from the OIS moving part, so that the moving distance of the OIS moving part required for image stabilization can be reduced.

[0259] That is, when tilting the OIS moving unit within a preset angle range (e.g., 1 degree correction) for image stabilization, the movement distance (rotation distance or tilting angle) of the OIS moving unit of the embodiment may be smaller than the movement distance (rotation distance or tilting angle) of the OIS moving unit of the comparative example. In the embodiment, since the movement distance (or rotation distance or tilting angle) is small, the power consumption required for image stabilization can be reduced.

[0260] In addition, in the embodiment, the moving distance of the OIS moving part required for image stabilization can be designed to be small, and thus the size of the driving plate (61) can be designed to be larger.

[0261] In addition, since the moving distance of the OIS moving part can be designed to be small in the embodiment, the size of the camera device (200) can be reduced. In addition, since the size of the driving plate (61) can be designed to be larger in the embodiment, the OIS moving part can be stably supported and guided when the OIS is driven.

[0262] In addition, the driving plate (61) does not directly contact the holder (30) and the driving plate (61) and the holder (30) do not directly collide due to impact. This makes it possible to suppress or prevent damage to the holder (30) and the optical member (40) due to collision with the driving plate (61).

FIG. 18b is a perspective view of the body (612) of the second housing (610), FIG. 19a is a first perspective view of the first and second guide parts (614A, 614B) and the lens part (620), FIG. 19 is a second perspective view of the first and second guide parts (614A, 614B) and the lens part (620), and FIG. 20 is an exploded perspective view of the first and second magnets (130A, 130B) and the lens part (620).

[0264] Referring to FIGS. 14 to 20, the first actuator (310) may include a second housing (610), a lens unit (620) disposed within the second housing (610), and a first driving unit (630) that moves the lens unit (620) in a first direction (e.g., in the optical axis direction or the Z-axis direction).

[0265] The lens unit (620) may be replaced with a “lens assembly.” For example, the lens unit (620) may include a plurality of lens assemblies.

[0266] In FIGS. 14 to 2, the lens unit (620) includes two lens assemblies (622, 624), but is not limited thereto. For example, the second lens assembly (622) and the third lens assembly (623) may be arranged in the first direction.

[0267] The first actuator (310) may further include a first lens assembly (640) positioned between the lens unit (620) and the second actuator (320). For example, the first lens assembly (640) may be a fixed lens assembly whose position is fixed and does not move in the optical axis direction.

[0268] The first lens assembly (640) may include a first lens array (642) (or a first lens group). For example, the first lens assembly (640) may further include a lens barrel (641) coupled with the first lens array (642). In addition, the first lens assembly (640) may further include a third housing (643) coupled with the lens barrel (641). The third housing (643) may be disposed between the second housing (610) and the first housing (50), and may be coupled with at least one of the second housing (610) and the first housing (50).

[0269] For example, at least one first coupling hole (643A) may be formed on the front side of the third housing (643) for coupling with at least one coupling protrusion (46A) of the second housing (610). In addition, a second coupling hole may be formed on the rear side of the third housing (643) for coupling with at least one coupling protrusion (52A) of the first housing (50).

[0270] The first lens assembly (640) is represented as being included in the first actuator (310), but is not limited thereto, and may be represented as not being included in the first actuator (310). In other embodiments, the first lens assembly (640) may be omitted.

[0271] Additionally, in other embodiments, any one of 640, 622, 624 may be represented as a “first lens assembly”, any other one of 640, 622, 624 may be represented as a “second lens assembly”, and any other one of 640, 622, 624 may be represented as a “third lens assembly”.

[0272] For example, in the embodiment, the first lens assembly (640) may be a fixed lens group, and each of the second lens assembly (622) and the third lens assembly (624) may include a moving lens group or lens groups.

[0273] For example, the first lens assembly (640) can perform a focal function that focuses parallel light at a specific location. In addition, the second lens assembly (622) can perform a variator function that refocuses the image focused by the first lens assembly (640), which is a condenser, at another location. Meanwhile, in the second lens assembly (622), the distance to the subject or the image distance may change significantly, so the magnification may change significantly, and the second lens assembly (622), which is a variator, may play an important role in changing the focal length or magnification of the optical system. Meanwhile, the image focused by the second lens assembly (6220), which is a variator, may slightly differ depending on the location.

[0274] Additionally, the third lens assembly (624) can perform a position compensation function for the image formed by the variable lens. For example, the third lens assembly (624) can perform a compensator function that accurately forms the image formed by the second lens assembly (622), which is a variable lens, onto the pixels of the image sensor (540).

[0275] For example, the second lens assembly (622) may be a zoom lens assembly that performs a zooming function, and the third lens assembly (624) may be a focus lens assembly that performs a focusing function.

[0276] Referring to FIGS. 2, 14, 15a, and 15b, the second housing (610) may be positioned between the first housing (50) and the image sensor unit (330) (e.g., sensor base (550)). The second housing (610) may also be expressed as a “base” or a “holder”.

[0277] The second housing (610) can be placed inside the cover member (300) and can have a polyhedral (e.g., rectangular parallelepiped) shape having a space therein to accommodate the lens unit (620) and the first driving unit (630).

[0278] For example, the second housing (610) may include a body (612) including an upper portion (142A) (or upper plate), a lower portion (142B) (or lower plate), and a plurality of side portions (141-1 to 141-4) disposed between the upper portion (142A) and the lower portion (142B). The upper portion (142A) of the second housing (610) may face the upper portion (301) of the cover member (300), and the side portions (141-1 to 141-4) may face the side plate (302) of the cover member (300).

[0279] The sides (141-1 to 141-4) may be alternatively referred to as “side plates” or “side walls.” For example, the first side (141-1) and the second side (141-2) may face each other in the first direction or be positioned opposite each other, and the third side (141-3) and the fourth side (141-3) may face each other in the third direction or be positioned opposite each other.

[0280] A first opening (41A) (or first hole) for exposing one end of the lens portion (620) may be formed in the first side (141-1) of the second housing (610), and a second opening (41B) (or second hole) for exposing the other end of the lens portion (620) may be formed in the second side (141-2) of the second housing (610).

[0281] Additionally, a third opening (41C) (or third hole) for placing or settling the first coil (120A) may be formed in the third side (141-3) of the second housing (610), and a fourth opening (41C) (or third hole) for placing or settling the second coil (120B) may be formed in the fourth side (141-4) of the second housing (610). Each of the third and fourth openings (41C, 41D) is in the form of a through hole, but is not limited thereto, and may also be in the form of a groove.

[0282] At least one first coupling protrusion (45A) that is coupled to the first circuit board (192) of the second substrate (190) may be formed on the third side (141-3) of the second housing (610). For example, at least one first coupling protrusion (45A) may protrude from the outer surface of the third side (141-3).

[0283] At least one second coupling protrusion (45B) that is coupled to the second circuit board (194) of the second substrate (190) may be formed on the fourth side (141-1) of the second housing (610). For example, at least one second coupling protrusion (45B) may protrude from the outer surface of the fourth side (141-4). In addition, at least one third coupling protrusion (46A) may be formed on the second side (141-2) of the second housing (610).

[0284] The second housing (610) may include a first guide portion (614A) and a second guide portion (614B). The first guide portion (614A) may support and guide the second lens assembly (622) when the lens portion (620) moves by a zooming operation. The second guide portion (614B) may support and guide the third lens assembly (624) when the lens portion (620) moves by a zooming operation.

[0285] The first guide part (614A) may be placed between the lens part (620) and the third side part (141-3), and the second guide part (614b) may be placed between the lens part (620) and the fourth side part (141-4).

[0286] For example, the first guide portion (614A) can be coupled to the third side portion (141-3) of the second housing (610), and the second guide portion (614B) can be coupled to the fourth side portion (141-4) of the second housing (610).

[0287] Referring to FIGS. 19A and 19B, the first guide portion (614A) may include at least one first guide groove (212A). The second guide portion (614B) may include at least one second guide groove (212B). Here, the guide groove may be expressed as a “rail” or a “groove.”

[0288] For example, each of the first guide portion (614A) and the second guide portion (614B) may include a body (63A) and a protrusion (63B) extending and protruding from the body (63A).

[0289] For example, the first guide groove (212A) may be formed on the inner surface of the body (63A) of the first guide portion (614A), and the second guide groove (212B) may be formed on the inner surface of the body (63A) of the second guide portion (614B). In this case, the inner surface of the body (63A) of each of the first and second guide portions (614A, 614B) may be a surface facing the lens portion (620).

[0290] In FIGS. 19A and 19B, one first guide groove (212A) is formed on the lower side of the inner surface of the body (63A) of the first guide portion (614A), and one second guide groove (212B) is formed on the upper side of the inner surface of the body (63A) of the second guide portion (614B), but this is not limited thereto. In other embodiments, a guide groove may be formed on at least one of the upper side and the lower side of the inner surface of the body of each of the first and second guide grooves. For example, each of the first and second guide grooves (212A, 212B) may be formed continuously from the front end to the rear end of the inner surface of the body (64A).

[0291] The protrusions (63B) of each of the first guide portion (614A) and the second guide portion (614B) may extend and protrude in a direction (e.g., a third direction) perpendicular to the direction in which the first and second guide grooves extend (e.g., a first direction). For example, the protrusions (63B) of the first guide portion (614A) and the protrusions (63B) of the second guide portion (614B) may protrude in opposite directions. For example, the protrusions (63B) may be formed on the rear or rear end of each of the first guide portion (614A) and the second guide portion (614B).

[0292] At least one hole (68) may be formed in the protrusion (63B) of each of the first and second guide portions (614A, 614B) to be coupled with the rear end of the body (612) of the second housing (610). For example, the hole (68) of the protrusion (63B) may be coupled with the coupling protrusion (46A) of the body (612) of the second housing (610). For example, the coupling protrusion (46A) may pass through the hole (68) of the protrusion (63B) and be coupled to the first coupling hole (643A) of the third housing (643).

[0293] At least one engaging protrusion (6A) that engages with the body (612) of the second housing (610) may be formed on the front or front end of each of the first guide portion (614A) and the second guide portion (614B). For example, a engaging hole (6B) that engages with the engaging protrusion (6A) of the first and second guide portions (614A, 614B) may be formed on the inner surface of the body (612) of the second housing (610) (see FIG. 18B).

[0294] Referring to FIG. 18B, guide protrusions (44A to 44D) for guiding the first and second guide portions (614A, 614B) may be formed on the inner surface of the body (612) of the second housing (610). For example, the first guide protrusion (44A) may be arranged on the inner surface of the lower portion (142B) of the second housing (610), and the second guide protrusion (44B) may be arranged on the inner surface of the upper portion (142A) of the second housing (610) corresponding to the first guide protrusion (44A) in the second direction. The first guide portion (614A) may be arranged in the space (49A) between the first and second guide protrusions (44A, 44B) and the third side portion (141-3) of the second housing (610).

[0295] Also, for example, the third guide protrusion (44C) may be arranged on the inner surface of the lower portion (142B) of the second housing (610), and the fourth guide protrusion (44D) may be arranged on the inner surface of the upper portion (142A) of the second housing (610) corresponding to the third guide protrusion (44C) in the second direction. The second guide portion (614B) may be arranged in the space (49B) between the third and fourth guide protrusions (44C, 44D) and the fourth side portion (141-4) of the second housing (610).

[0296] The first and second guide portions (614A, 614B) can be stably coupled to the body of the second housing (610) by the first to fourth guide protrusions (44A to 44D), and the first and second guide portions (614A, 614B) can be prevented from being detached from their original positions or colliding with the lens portion (620) due to impact or the like.

[0297] The first guide portion (614A) may have a first opening (67A) (or hole) corresponding to, opposite to, or overlapping with the first magnet (130A). For example, the first opening (67A) may be located between the first magnet (130A) and the first coil (120A).

[0298] The second guide portion (614B) may have a second opening (67B) (or hole) corresponding to, opposite to, or overlapping with the second magnet (130B). For example, the first opening (67B) may be located between the second magnet (130B) and the second coil (120B). The electromagnetic force due to the interaction between the first magnet (130A) and the first coil (120A) and the electromagnetic force due to the interaction between the second magnet (130B) and the second coil (120B) may be increased by the first and second openings (67A, 67B).

[0299] In FIGS. 18A and 18B, the first and second guide portions (614A, 614B) and the body (612) of the second housing (610) are formed as separate injection molded products, and the separate objects are combined with each other, but this is not limited to this. In other embodiments, the first and second guide portions may be formed as a single injection molded product with the body of the second housing.

[0300] An opening (621) exposing a portion of a lens portion (620) may be formed in the upper portion (142A) of the body (612) of the second housing (610), and the second housing (610) may further include a cover (614) covering the opening (621). In other embodiments, the opening (621) may not be formed, and the cover (614) may be omitted.

[0301] The lens unit (620) may include a second lens assembly (622) that moves along the first guide unit (614A) and a third lens assembly (624) that moves along the second guide unit (614B).

[0302] Referring to FIGS. 19A, 19B, and 20, the second lens assembly (622) may include a first lens holder (29) and a second lens array (49) (or second lens group) disposed in the first lens holder (29). The lens holder may be alternatively expressed as a “bobbin.”

[0303] The second lens array (49) may include a single lens or multiple lenses.

[0304] The first lens holder (29) may include a first lens barrel (29A) in which a second lens array (49) is arranged and a first support member (29B) coupled with the first lens barrel (29A). For example, the first lens barrel (29A) may have a barrel shape and may include an opening (29C) (or hole) for coupling the second lens array (49).

[0305] The first side (or first surface) of the first support member (29B) can be coupled to the first lens barrel (29A). The first support member (29B) can correspond to, face, or overlap with the body (63A) of the first guide member (614A) in the third direction.

[0306] A first mounting portion (30A) may be formed on the second side (or second surface) of the first support portion (29B) to place or mount the first magnet (130A). The second side (or second surface) of the first support portion (29B) may be a surface facing the first guide portion (614A) and may be an opposite surface of the first side (or first surface) of the first support portion (29B).

[0307] For example, the first mounting portion (30A) may include a first mounting surface (11A) formed in one area (e.g., a central area) of the second side (or second surface) of the first support portion (29B) and at least one first supporting protrusion (11B) protruding from the first mounting surface (11A). In FIG. 18, the first mounting portion (30A) includes four first supporting protrusions formed at four corners of the second side of the first support portion (29B), and the four first supporting protrusions may support the first magnet (130A). In other embodiments, the number of first supporting protrusions of the first mounting portion may be one or two or more.

[0308] The first support member (29B) may include at least one first groove (13A) (or first guide groove) for accommodating at least a portion of the first cloud member (12A). For example, at least one first groove (13A) may correspond to, face, or overlap at least one first guide groove (212A) of the first guide member (614A).

[0309] For example, two first grooves spaced apart from each other may be formed on the mounting surface (11A) of the first mounting portion (30A), and two first grooves spaced apart from each other may be formed below the mounting surface (11B). In another embodiment, two grooves formed above or below the mounting surface (11B) may be connected to each other to form one groove. For example, the number of grooves may be the same as the number of balls (B11 to B14), but is not limited thereto.

[0310] The third lens assembly (624) may include a second lens holder (39) and a third lens array (59) (or third lens group) disposed in the second lens holder (39). The third lens array (59) may include a single lens or a plurality of lenses.

[0311] A plurality of lenses included in each of the second and third lens arrays (49, 59) may be sequentially arranged or arranged in the first direction. For example, each of the second and third lens arrays (49, 59) may include various types of optical lenses. For example, each of the second and third lens arrays (49, 59) may include at least one of a front lens having positive power and a rear lens having negative power.

[0312] The distance in the optical axis direction between the second lens group and the third lens group can be varied by the first driving unit (630).

[0313] The second lens holder (39) may include a second lens barrel (39A) in which the third lens array (59) is arranged and a second support member (39B) coupled with the second lens barrel (39A). For example, the second lens barrel (39A) may have a barrel shape and may include an opening (39C) (or hole) for coupling the second lens array (49).

[0314] The first side (or first surface) of the second support member (39B) can be coupled to the second lens barrel (39A). The second support member (39B) can correspond to, face, or overlap with the body (63A) of the second guide member (614B) in the third direction.

[0315] A second mounting portion (30B) may be formed on the second side (or second surface) of the second support portion (39B) to place or mount the second magnet (130B). The second side (or second surface) of the second support portion (39B) may be a surface facing the second guide portion (614B) and may be an opposite surface of the first side (or first surface) of the second support portion (39B).

[0316] For example, the second anchoring portion (30B) may include a second anchoring surface formed in one area (e.g., a central area) of the second side (or second surface) of the second support portion (39B) and at least one second support protrusion protruding from the second anchoring surface. The description of the first anchoring surface (11A) and the first support protrusion (11B) of the first support portion (29B) may be applied or mutatis mutandis to the second anchoring surface and the second support protrusion of the second support portion (29B).

[0317] The second support member (39B) may include at least one second groove (13B) (or second guide groove) for accommodating at least a portion of the second cloud member (12B). For example, at least one second groove (13B) may correspond to, be opposite to, or overlap at least one second guide groove (212B) of the second guide member (614B). The description of the first groove (13A) of the first support member (30A) may be applied or mutatis mutandis to the second groove (13B) of the second support member (30B).

[0318] Each of the first and second guide grooves (212A, 212B) and the first and second grooves (13A, 13B) may have a V or U shape, but is not limited thereto, and may have a shape that makes contact with the balls (B11 to B14, B21 to B24) at two or more points. The second and third lens assemblies (622, 624) can be prevented from being decentered or tilted when moved by the first and second guide grooves (212A, 212B) and the first and second grooves (13A, 13B). As a result, the alignment between the plurality of lens arrays is well matched, preventing the change in the angle of view or the occurrence of out-of-focus, so that the image quality or resolution of the camera device (200) can be significantly improved.

[0319] The first actuator (310) may further include a cloud member (12A, 12B) disposed between the second housing (610) and the lens unit (620). For example, the cloud member (12A, 12B) may be disposed between the guide member (614A, 614B) of the second housing (610) and the groove (13A, 13B) of the support member (39A, 39B) of the lens unit (620).

[0320] The cloud member may be expressed as a “ball member”, “ball”, or “ball bearing”. For example, the cloud member (12A, 12B) may include at least one ball.

[0321] The cloud members (12A, 12B) can be in contact with the second housing (610) and the lens unit (620) and can support the lens unit (620). When the lens unit (620) moves in the first direction, the cloud members (12A, 12B) can reduce friction between the lens unit (620) and the second housing (610) by performing a rolling motion between the lens unit (620) and the second housing (610). That is, by the rolling motion of the cloud members (12A, 12B), the lens unit (620) can be moved in a sliding manner in the first direction along the first and second guide units (614A, 614B) by coming into contact with the cloud members (12A, 12B).

[0322] For example, the cloud member may include a first cloud member (12A) and a second cloud member (12B). The first cloud member (12A) may be disposed between the first guide portion (614A) of the second housing (610) and the second lens assembly (622) (e.g., the first support portion (29B)). The second cloud member (12B) may be disposed between the second guide portion (614B) of the second housing (610) and the third lens assembly (624) (e.g., the second support portion (39B)).

[0323] The first cloud member (12A) may include a plurality of balls (B11 to B14), and the second cloud member (12B) may include a plurality of balls (B21 to B24). Each of the balls (B11 to B14, B221 to B24) may be made of a metal material, a plastic material, or a resin material, but is not limited thereto. Each of the balls (B11 to B14, B221 to B24) may have a circular shape and may have a diameter sufficient to support the movement of the lens unit (620).

[0324] Next, the first driving unit (630) will be described.

[0325] The first driving unit (630) can move the second lens assembly (622) in the first direction and the third lens assembly (624) in the first direction. For example, the first driving unit (630) can move at least one lens group, for example, the second lens group or the third lens group, in the first direction or the optical axis direction.

[0326] The first driving unit (630) may include a magnet (130) disposed in the lens unit (620) and a coil (120) disposed in the second housing (610). For example, the magnet (130) may include a first magnet (130A) disposed in the second lens assembly (622) and a second magnet (130B) disposed in the third lens assembly (624).

[0327] For example, the first magnet (130A) may be placed in the first lens holder (29) of the second lens assembly (622), and the second magnet (130B) may be placed in the second lens holder (39) of the third lens assembly (624). For example, the first magnet (130A) may be placed in the first mounting portion (30A) of the first support portion (29B) of the first lens holder (29), and the second magnet (130B) may be placed in the second mounting portion (30B) of the second support portion (39B) of the second lens holder (39).

[0328] For example, each of the first and second magnets (130A, 130B) may be a unipolar magnet including one N pole and one S pole. In another embodiment, each of the first and second magnets (130A, 130B) may be a bipolar magnet including two N poles and two S poles.

[0329] The coil (120) may include a first coil (120A) corresponding to, opposite to, or overlapping with the first magnet (130A) in a third direction and disposed on a third side (142-3) of the second housing (610), and a second coil (120B) corresponding to, opposite to, or overlapping with the second magnet (130B) in a third direction and disposed on a fourth side (142-4) of the second housing (610).

[0330] For example, each of the first coil (120A) and the second coil (120B) may be in the form of a closed curve or ring having a hollow (or hole). For example, each of the first coil (120A) and the second coil (120B) may be in the form of a coil ring wound clockwise or counterclockwise around (or as the center of) a third axis parallel to the third direction.

[0331] For example, the N pole and the S pole of the first magnet (130A) may be arranged to face the first coil (120A), and the N pole and the S pole of the second magnet (130B) may be arranged to face the second coil (120B). For example, the hollow or hole of each of the first and second coils (120A, 120B) may face the first and second magnets (130A, 130B) in a third direction.

[0332] A first driving signal (e.g., a first current) may be applied to the first coil (120A), and a second driving signal (e.g., a second current) may be applied to the second coil (120B). The first lens assembly (622) may be moved in the first direction by an electromagnetic force resulting from the interaction between the first coil (120A) and the first magnet (130A). In addition, the second lens assembly (624) may be moved in the first direction by an electromagnetic force resulting from the interaction between the second coil (120B) and the second magnet (130B).

[0333] By controlling the first driving signal and the second driving signal, the movement of each of the first lens assembly (622) and the second lens assembly (624) can be controlled. As the movement of each of the first lens assembly (622) and the second lens assembly (624) is controlled, the position (or displacement) of each of the first lens assembly (622) and the second lens assembly (624) can be controlled, thereby performing zooming and auto-focusing of the camera device (200).

[0334] Referring to FIG. 20, the first driving unit (630) may further include a first yoke (19-1) disposed in the first lens holder (29) and a second yoke (19-2) disposed in the second lens holder (39). The first yoke (19-1) may increase an electromagnetic force due to an interaction between the first magnet (130A) and the first coil (120A), and the second yoke (19-2) may increase an electromagnetic force due to an interaction between the second magnet (130B) and the second coil (120B). The driving force for moving the lens unit (620) may be improved by the first and second yokes (19-1, 19-2), thereby reducing power consumption.

[0335] For example, the first yoke (19-1) may be placed between the first magnet (130A) and the first lens holder (29), and the second yoke (19-2) may be placed between the second magnet (130B) and the second lens holder (39). For example, the first yoke (19-1) may be placed on the first mounting portion (30A) of the first support portion (29B), and the second yoke (19-2) may be placed on the second mounting portion (30B) of the second support portion (39B).

[0336] For example, the first yoke (19-1) may include a first portion (19A) facing the first magnet (130A) in the third direction and disposed on the first mounting surface (11A), and a second portion (19B) extending from at least one of one end and the other end of the first portion (19A). For example, the second portion (19B) may include a 2-1 portion supporting one end of the first magnet (130A) and a 2-2 portion supporting the other end of the first magnet (130A).

[0337] The first driving unit (630) may further include a second substrate unit (190) electrically connected to the first coil (120A) and the second coil (120B). For example, the second substrate unit (190) may be a printed circuit board.

[0338] The second substrate portion (190) may be disposed in the second housing (610). For example, the second substrate portion (190) may include a first circuit substrate (192) disposed on a third side (142-3) of the second housing (610) and a second circuit substrate (194) disposed on a fourth side (142-4) of the second housing (610). For example, the first circuit substrate (192) may include at least one hole (192A) for engaging with at least one first engaging protrusion (45A) of the second housing (610), and the second circuit substrate (194) may include at least one hole (194A) for engaging with at least one second engaging protrusion (45B) of the second housing (610).

[0339] The first coil (120A) may be placed or mounted on the first surface of the first circuit board (192). At this time, the first surface of the first circuit board (192) may be a surface facing the third side (142-3) of the second housing (610) in the third direction. The second coil (120B) may be placed or mounted on the first surface of the second circuit board (194). At this time, the first surface of the second circuit board (194) may be a surface facing the fourth side (142-4) of the second housing (610) in the third direction.

[0340] The first circuit board (192) may be electrically connected to the first coil (120A). For example, two pads electrically connected to the first coil (120A) may be formed on a first surface of the first circuit board (192). In addition, the first circuit board (192) may include a plurality of terminals (254A). For example, the plurality of terminals (254A) may be formed on a second surface of the first circuit board (192). For example, the second surface of the first circuit board (192) may be an opposite surface of the first surface of the first circuit board (192). For example, two terminals among the plurality of terminals (254A) may be electrically connected to two pads of the first circuit board (192) that are connected to the first coil (120A) and may be electrically connected to the first coil (120A).

[0341] The second circuit board (194) may be electrically connected to the second coil (120B).

In addition, the second circuit board (194) may include a plurality of terminals (254B).

[0342] For example, a plurality of terminals (254b) may be formed on the second surface of the second circuit board (194). For example, the second surface of the second circuit board (194) may be the opposite surface of the first surface of the circuit board (192). Although the terminals (254b) are not specifically visible in FIG. 17, terminals (254B) may be formed on the second surface of the second circuit board (194) in the same form as the terminals (254a) of the first circuit board (192).

[0343] For example, two terminals among the plurality of terminals (254B) can be electrically connected to two pads of the second circuit board (194) that are connected to the second coil (120B) and can be electrically connected to the second coil (120B).

[0344] The second driving unit (70) may include a first position sensor unit (170) for performing feedback driving for accurate zooming and AF operation.

[0345] The first position sensor unit (170) may include a first position sensing unit (71) for detecting the position or displacement of the second lens assembly (622) and a second position sensing unit (72) for detecting the position or displacement of the third lens assembly (624).

[0348] For example, the first position sensing unit (71) may face or overlap the first magnet (130A) in the third direction. For example, the first position sensing unit (71) may be placed on the opposite side of the first magnet (130A).

[0349] The strength of the magnetic field of the first magnet (130A) can be detected. For example, the first position sensing unit (71) can detect the movement of the first magnet (130A) in the direction of the optical axis.

[0350] The second position sensing unit (72) may face or overlap the second magnet (130B) in the third direction. For example, the second position sensing unit (72) may be placed on the opposite side of the second magnet (130B).

[0352] For example, the first position sensing unit (71) may include a first sensor (71A) and a second sensor (71B). For example, each of the first and second sensors (71A, 71B) may be a Hall sensor. For example, the first sensor (71A) and the second sensor (71B) may be arranged spaced apart from each other in the first direction.

[0353] For example, the second position sensing unit (72) may include a third sensor (72A) and a fourth sensor (72B). For example, each of the third and fourth sensors (72A, 72B) may be a Hall sensor. For example, the third sensor (72A) and the fourth sensor (72B) may be arranged spaced apart from each other in the first direction.

[0354] In FIG. 17, each of the first position sensing unit (71) and the second position sensing unit (72) includes two sensors, but in other embodiments, each of the first position sensing unit and the second position sensing unit may include one sensor, and in this case, one sensor may be in the form of a Hall sensor or a driver IC including a Hall sensor.

[0355] The camera device (200) may include a memory (596) arranged on the second substrate (190). For example, the memory (596) may be a non-volatile memory, such as an Electrically Erasable PROM (EEPROM).

[0356] For example, the memory (596) may be placed or mounted on the second circuit board (194) and may be electrically connected to the second circuit board (194). For example, the memory (596) may store data required for driving the driving unit. At this time, the driving unit may include at least one of the first driving unit (630) and the second driving unit (70). For example, the memory (596) may store at least one of data of the first position sensing unit (71) corresponding to the movement range of the second lens group and data of the second position sensing unit (72) corresponding to the movement range of the third lens group.

[0357] At this time, the data of the first position sensing unit (71) may be data (or reference code value) regarding the output of the first position sensing unit (71) corresponding to the movement range of the second lens group obtained through calibration. In addition, the data of the second position sensing unit (72) may be data (or reference code value) regarding the output of the second position sensing unit (72) corresponding to the movement range of the third lens group obtained through calibration.

[0358] Additionally, the memory (596) can store data of the first OIS position sensor (240A, 240B) corresponding to the second axis (X-axis) tilting range of the OIS moving unit.

For example, the first actuator according to other embodiments may be a fixed zoom actuator that performs an autofocus function.

[0392] Fig. 21 shows a functional block diagram of a camera device (200) according to an embodiment.

[0393] Referring to FIG. 21, the camera device (200) may include a first driving unit (630), a second driving unit (70), a first position sensor unit (170), a second position sensor unit (240), a storage unit (180), an image sensing unit (600), and a control unit (810).

[0394] The first driving unit (630) receives a first driving signal, applies the received first driving signal to the first coil (120A), and moves the second lens assembly (622) in the first direction by interaction between the first coil (120A) and the first magnet (130A).

[0395] Additionally, the first driving unit (630) receives a second driving signal, applies the received second driving signal to the second coil (120B), and moves the third lens assembly (624) in the first direction by interaction between the second coil (120B) and the second magnet (130B).

[0396] The second driving unit (70) receives the first OIS driving signal, applies the received first OIS driving signal to the first OIS coil (230A, 230B), and rotates the OIS moving unit (e.g., holder (30)) by a preset angle around the second axis (e.g., X-axis) as the rotation axis through interaction between the first OIS coil (230A, 230B) and the first OIS magnet (31A, 31B).

[0397] In addition, the second driving unit (70) receives a second OIS driving signal, applies the received second OIS driving signal to the second OIS coil (230C), and rotates the OIS moving unit (e.g., holder (30)) by a preset angle around the third axis (e.g., Y axis) as the rotation axis through interaction between the second OIS coil (230C) and the second OIS magnet (32).

[0398] The second driving unit (70) can move on a plane (e.g., XY plane) perpendicular to the first axis (optical axis or Z axis) in which the path of light incident on the optical member (40) is caused by the movement of the holder (30) coupled with the optical member (40), thereby moving the image formed on the image sensor (540) in the X-axis direction and / or the Y-axis direction. That is, by controlling the movement of the holder (30), the embodiment can correct blurring of an image or shaking of a video caused by shaking of a camera device when taking an image or shooting a video due to the user's hand shaking.

[0399] The first position sensor unit (170) receives a first driving signal and supplies the received first driving signal to the first sensor (71A) and the second sensor (71B). The first position sensor unit (170) receives a second driving signal and supplies the received second driving signal to the third sensor (72A) and the fourth sensor (72B).

[0400] The first position sensor unit (170) detects the displacement of the second lens assembly (622) and outputs a first output signal based on the detection result. In addition, the first position sensor unit (170) detects the displacement of the third lens assembly (624) and outputs a second output signal based on the detection result.

[0401] The second position sensor unit (240) supplies a driving signal to each of the first sensor (240A), the second sensor (240B), and the second OIS position sensor (240C) of the first OIS position sensor. The first OIS position sensors (240A, 240B) can detect displacement of the OIS moving unit (e.g., holder (30)) in the third-axis direction and output an output signal according to the detected result. The second OIS position sensor (240C) can detect displacement of the OIS moving unit (e.g., holder (30)) in the second-axis direction and output an output signal according to the detected result. For example, the displacement in the third-axis direction may be a tilted position or displacement of the OIS moving unit with respect to the second axis, and the displacement in the second-axis direction may be a tilted position or displacement of the OIS moving unit with respect to the third axis.

[0402] The storage unit (180) stores data necessary to operate the camera device (200). The storage unit (180) may also be expressed as a "memory." For example, the storage unit (180) may store information on the zoom position and focus position according to the distance from the subject.

[0403] For example, the storage unit (180) can store a first reference code value (or data) regarding a first output signal of the first position sensing unit (71) corresponding to the movement range (or stroke range or displacement) of the second lens assembly (622). In addition, the storage unit (180) can store a second reference code value (or data) regarding a second output signal of the second position sensing unit (72) corresponding to the movement range (or stroke range or displacement) of the third lens assembly (624). The first and second reference code values ​​may be values ​​stored in advance in the storage unit (180) through calibration.

[0404] The storage unit (180) may be a separate configuration from the control unit (810), but is not limited thereto, and in other embodiments may be included in the control unit (810). For example, the storage unit (180) may be included in at least one of the first driver (542) and the second driver (260).

[0405] For example, the focus of the camera device (200) can be accurately adjusted based on the target position of the second lens assembly (622) and the target position of the third lens assembly (624).

[0406] The image sensing unit (330) may include an image sensor (540) that converts light reflected from a subject into an electrical signal. For example, the image sensor (540) may include a light receiving unit that receives light and converts it into an electrical signal, and an analog-to-digital converter that converts the converted electrical signal into a digital signal. In addition, for example, the image sensor (540) may further include an image signal processor that performs signal processing on the digital signal.

[0407] The control unit (810) controls the overall operation of the camera device (200). For example, the control unit (200) may control the first position sensor unit (170) and the second position sensor unit (240) and drive the first driving unit (630) and the second driving unit (70) to provide an anti-shake function, an auto-focus function, and a magnification adjustment function. For example, the control unit (810) may include a first driver (542) and a second driver (260). For example, each of the first driver (542) and the second driver (260) may include at least one of an analog-to-digital converter, an amplifier, a PID controller, or a memory.

[0408] The first driver (542) receives the output signal of the first position sensor unit (170), generates a first code value according to the result of analog-to-digital conversion of the received output signal, and controls a driving signal applied to the first coil (120) of the first driving unit (630) based on the result of comparing the generated first code value with the first target value. For example, the first target value may be a reference code value corresponding to the target zoom position of the second lens assembly (622).

[0409] The second driver (260) receives an output signal of the first OIS position sensor (240A, 240B) of the second position sensor unit (240), generates a second code value according to the result of analog-to-digital conversion of the received output signal, and controls a first driving signal applied to the first OIS coil (230A, 230B) of the second driving unit (70) based on the result of comparing the generated second code value with the second target value.

[0410] In addition, the second driver (260) can receive an output signal of the second OIS position sensor (240C) of the second position sensor unit (240), generate a third code value according to the result of analog-to-digital conversion of the received output signal, and control a second driving signal applied to the second OIS coil (230C) of the second driving unit (70) based on the result of comparing the generated third code value with the third target value.

[0411] For example, the second target value may be a reference code value (or data) regarding the output of the first OIS position sensor (240A, 240B) corresponding to the target second-axis (X-axis) tilting position of the OIS moving unit of the second actuator (320). Also, for example, the third target value may be a reference code value (or data) regarding the output of the second OIS position sensor (240C) corresponding to the target third-axis (Y-axis) tilting position of the OIS moving unit of the second actuator (320). The reference code values ​​(or data) regarding the outputs of each of the first OIS position sensors (240A, 240B) and the second OIS position sensor (240C) may be preset through calibration and stored in the storage unit (180).

[0412] The camera device (200) may further include a temperature sensor (566) for temperature compensation. The temperature sensor (566) may output temperature information based on the results of measuring the temperature of the camera device (200).

[0413] Temperature information of the temperature sensor (566) can be used for temperature compensation for the focusing operation of the third lens assembly (624). For example, the storage unit (180) can store a compensation value corresponding to the temperature information.

[0414] For example, since the second lens assembly (622) responsible for zooming moves according to the magnification set by the user, temperature compensation for the third lens assembly (624) responsible for auto-focusing can be performed while the position of the second lens assembly (622) is fixed (or under certain conditions).

[0415] Additionally, for example, the control unit (810) may receive temperature information from the temperature sensor (566), obtain a compensation value for temperature compensation corresponding to the received temperature information, and control the driving signal of the second coil (120B) of the third lens assembly (624) based on the obtained compensation value. As a result, in the embodiment, an accurate auto-focusing operation reflecting temperature compensation can be performed.

[0416] In addition, the camera device (200) according to the embodiment may be included in an optical instrument that forms an image of an object in space by using the characteristics of light such as reflection, refraction, absorption, interference, and diffraction, and aims to increase the visual acuity of the eye, or to record and reproduce an image using a lens, or to optically measure, propagate or transmit an image, etc. For example, the optical device according to the embodiment may be a mobile phone, a smart phone, a portable smart device, a digital camera, a laptop computer, a digital broadcasting terminal, a PDA (Personal Digital Assistants), a PMP (Portable Multimedia Player), a navigation system, etc., but is not limited thereto, and any device for taking a video or a photo may be used.
