[0071] Hereinafter, embodiments of the present invention that can specifically achieve the above purpose will be described with reference to the attached drawings.

[0072] 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.

[0073] 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.

[0074] 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."

[0075] 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 it 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 optical axis (OA) direction.

[0076] Additionally, the Z-axis direction, which is the optical axis (OA) direction, can be defined as 'any one of the first to third directions', the X-axis direction can be defined as 'another one of the first to third directions', and the Y-axis direction can be defined as 'the remaining one of the first to third directions'.

[0077] Additionally, the first axis, the second axis, and the third axis can intersect each other. The second axis can intersect the first axis, and the third axis can intersect the first and second axes. For example, the second axis can be perpendicular to the first axis, and the third axis can be perpendicular to the first and second axes. For example, the Z-axis can be defined as any one of the first to third axes, the Y-axis can be defined as any other one of the first to third axes, and the X-axis can be defined as any other one of the first to third axes. The Z-axis direction can be defined as any one of the first to third axes directions, the Y-axis direction can be defined as any other one of the first to third axes directions, and the X-axis direction can be defined as any other one of the first to third axes directions. For example, the optical axis direction can be the direction of the optical axis or a direction parallel to the optical axis. Alternatively, the optical axis direction can be a direction perpendicular to a sensor surface of an image sensor.

[0078] In addition, the expression "terminal" below may be expressed as a pad, electrode, or conductive layer. In addition, the expression "code value" below may be expressed as a data or digital value. In addition, in the embodiment, in the coupling between a protrusion and a 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).

[0079] 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 increases or decreases the magnification of a distant subject through a zoom lens to take a picture. Hereinafter, the "camera device" may be expressed as a "camera", a "camera module", a "camera", or a "camera".

[0089] The camera device (200) may include an optical member (40) that irradiates light to a lens assembly (622, 624), a third driving unit that tilts the optical member (40) based on a second axis intersecting the first axis, a fourth driving unit that tilts the optical member (40) based on a third axis intersecting the first and second axes, a sensor (240A) that detects a tilted displacement (or position) of the optical member (40) based on the second axis and outputs a signal (HV1), and a sensor (240B) that detects a tilted displacement of the optical member (40) based on the third axis and outputs a signal (HV2).

[0091] The second actuator (320) may include an optical member (40) that changes the path of light so that light passes through the opening (303) of the cover member (300) and is incident on the first actuator (310), and a driving unit (70) that rotates the optical member (40) by a preset angle in a direction perpendicular to the optical axis direction (e.g., the Z-axis direction) (e.g., the X-axis direction or the Y-axis direction).

[0092] 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 may be a mirror in other embodiments. The optical member (40) may be placed in the holder (30). The optical member (40) may change the optical path of incident light into an optical axis parallel to the central axis (Z) of the lens unit, thereby changing the incident light into parallel light, and the parallel light may pass through the first lens assembly (640), the second lens assembly (622), and the third lens assembly (624) to reach the image sensor (540).

[0093] 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 exit it on 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. In addition, for example, the first interior angle between the incident surface (8A) and the reflective surface (8C) and the second interior angle between the exit surface (8B) and the reflective surface (8C) may each be 30 to 60 degrees. For example, the first interior angle and the second interior angle may each be 45 degrees, but are not limited thereto. And, 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.

[0094] 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 member (60) disposed between the holder (30) and the housing (50). In addition, the second actuator (320) may include a driving member (70).

[0095] 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.

[0096] For example, an adhesive for attaching the optical member (40) to the mounting surface (104a) of the holder (30) may be disposed, and at least one groove (104b) for receiving the adhesive may be formed in the mounting surface (104a). 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 one side (front outer side, 31a) of the holder (30) facing a lens assembly (e.g., 311) of the first actuator (310). The emission surface (8B) of the optical member (40) mounted on the holder (30) can be arranged to face the lens assembly (e.g., 311) of the first actuator (310).

[0097] Referring to FIG. 6A, 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 a rear outer surface (31b) of the holder (30), and the second surface (18B) may be positioned adjacent to or in contact with a front outer surface (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). 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.

[0098] 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).

[0099] 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).

[0100] For example, the front outer surface (31a) of the holder (30) is referred to as the outer surface of the first side of the holder (30), the rear outer surface (31b) of the holder (30) is referred to as the outer surface of the second side of the holder (30), the side (31c) of the holder (30) is referred to as the third side of the holder (30), and the side (31d) of the holder (30) is referred to as the fourth side (31d) of the holder (30).

[0101] Each of the third and fourth sides (31c, 31d) of the holder (30) may include a first outer side surface (19A) and a second outer side surface (19B) having a step in a third direction (e.g., Y-axis direction) from the first outer side surface (19A). The first outer side surface (19A) may be positioned adjacent to or in contact with the rear outer side surface (31b) of the holder (30), and the second outer side surface (19B) may be positioned adjacent to or in contact with the front outer side surface (31a) of the holder (30). The second outer side surface (19B) may be positioned closer to the inner side surface of the holder (30) than the first outer side surface (19A).

[0102] 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.

[0103] 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).

[0104] 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 a front outer surface (31a) of the holder (30), and the second surface (17B) may be positioned adjacent to or in contact with a rear outer surface (31b) of the holder (30). The first surface (17A) may be positioned lower than the second surface (17B). For example, the second surface (17B) may be positioned closer to the upper surface (18) of the holder (30) than the first surface (17A). 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 (230B) can be prevented.

[0105] 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 second surface (17B)) 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 difference between the first surface (17A) and the second surface (17B) of the lower surface (17) of the holder (30).

[0106] The holder (30) may include a first mounting groove (16A) for placing or settling the first OIS magnet (31) and a second mounting groove (16B) for placing or settling the second OIS magnet (32). For example, the first mounting groove (16A) may be formed on an outer surface (e.g., a first outer surface (19A)) of each of the third and fourth side portions (31c, 31d) of the holder (30). For example, the first mounting 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).

[0107] For example, the second mounting groove (16B) may be formed on the lower surface (17) (e.g., the second surface (16B)) 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 second surface (16B)) of the holder (30).

[0108] Referring to FIG. 6b, the rear outer surface (31b) of the holder (30) may include a first surface (21a), a second surface (21b) adjacent to or in contact with a third side (31c), and a third surface (21c) adjacent to or in contact with a fourth side (31d). When viewed from the rear, the first surface (21a) may be positioned in the center, the second surface (21b) may be positioned on the left side of the first surface (21a), and the third surface (21c) may be positioned on the right side of the first surface (21a). Each of the second surface (21b) and the third surface (21c) may have a step from the first surface (21a) in the first direction (e.g., the Z-axis direction). For example, the first surface (21a) may be positioned closer to the inner surface of the holder (30) 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. Or, 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.

[0109] For example, a groove (106) for seating or accommodating a mover plate (61) may be formed on the rear outer surface (31b) of the second side of the holder (30). For example, the groove (106) may be arranged in the center of the rear outer surface (31b) and may be recessed from the rear outer surface (31b). The holder (30) may include at least two grooves (36A, 36B) formed on the first surface (21a) of the rear outer surface (31b) and corresponding to at least two front protrusions (61B1, 61B2) of the mover plate (61). For example, at least two grooves (36A, 36B) of the holder (30) may be arranged to be spaced apart from each other in the second direction and may be formed on the bottom surface of the groove (106). For example, the holder (30) may include a second groove (36B) formed on the first surface (21a) of the rear outer surface (31b) and a first groove (36A) spaced apart from the second groove (36B) and positioned above the second groove (36B). In another embodiment, the first groove may be positioned above the second groove.

[0110] For example, the first groove (36A) may include a bottom surface 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 (36A) may be different from the area of ​​at least another of the plurality of side surfaces (1A to 1D) of the first groove (36A). For example, two side surfaces (1C, 1D) of the first groove (36A) facing each other in a third 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 (36A) facing each other in a second direction may have a symmetrical shape, and the areas of the two side surfaces (1A, 1B) may be the same. The first area of ​​each of the side surfaces (1C, 1D) of the first groove (36A) facing in the third direction may be different from the second area of ​​each of the side surfaces (1A, 1D) of the first groove (36A) facing in the second 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 (36A) may be rectangular or oval, but is not limited thereto.

[0111] The second groove (36B) may include a bottom surface and a plurality of side surfaces. Each of the plurality of side surfaces of the second groove (36B) may have the same shape. In FIG. 6B, the number of side surfaces of the second groove (36B) is four, but is not limited thereto, and in other embodiments, may be five or more. 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. If both the first and second grooves of the holder (30) have the shape of the second groove (36B) illustrated in FIG. 6B, a manufacturing tolerance may occur with respect to the first and second grooves of the holder (30) or / and the front protrusions of the driving plate (61), and as a result, the front protrusions of the driving plate (61) may not be properly or stably coupled to the first and second grooves of the holder (30).

[0112] In an embodiment, by making the shape of the first groove (36A) different from that of the second groove (36B), the coupling margin between the front protrusions (61B1, 61B2) of the driving plate (61) and the first and second grooves (36A, 36B) of the holder (30) can be increased. That is, even if the above-described manufacturing tolerance occurs, the front protrusions (61B1, 61B2) of the driving plate (61) can be suitably or stably coupled to the first and second grooves (36A, 36B) of the holder (30) by the first groove (36A), and stable OIS operation can be possible. However, in another embodiment, each of the first groove and the second groove of the holder (30) may have the same shape. For example, in another embodiment, each of the first groove and the second groove of the holder (30) may have the shape of the first groove (36A) or the second groove (36B) of FIG. 6b.

[0113] A protrusion or step may be formed around the second groove (36B) and the first groove (36A). The protrusion may be in the form of a protrusion protruding from the first surface (21a) of the rear outer surface (31b). A lubricant may be placed between the front projections (61B1, 61B2) and the first and second grooves (36A, 36B), and the protrusion formed around the first groove (36A) and the second groove (36B) may prevent the lubricant from overflowing. At least one engaging groove (105A, 105B) may be formed on the rear outer surface (31b) of the holder (30) for engaging with the magnetic support member (64). For example, the holder (30) may include a first coupling groove (105A) formed on the second surface (21b) of the rear outer surface (31b), and a second coupling groove (105B) formed on the third surface (21c). For example, at least one protrusion (2A) (or groove) may be formed on at least one of the side surface and the bottom surface of each of the first and second coupling grooves (105A, 105B). For example, at least one protrusion (2A) may correspond to at least one groove (7B) of the magnetic support member (64) or may be formed at a position corresponding to at least one groove (7B). Grooves (4A) for placing an adhesive may be formed on at least one of the side surface and the bottom surface of each of the first and second coupling grooves (105A, 105B). The bonding area between the adhesive and the magnetic support (64) can be increased by the grooves (4A), and the bonding force between the holder (30) and the magnetic support (64) can be improved. The holder (30) can include at least one stopper (not shown) formed on the rear outer surface (31b). For example, the stopper can be in the form of a protrusion or projection protruding from each of the second surface (21b) and the third surface (21c) of the rear outer surface (31b).

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

[0115] Referring to FIGS. 9A to 9C, 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) and a second opening (53B) (or second hole) for exposing the exit surface (8B) of the optical member (40).

[0116] 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) may face each other in a second direction (e.g., in the X-axis direction) or may be positioned opposite to each other.

[0117] 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). For example, the first side (28A) of the first housing (50) may be arranged to face or be opposite a lens assembly (e.g., 311) of the first actuator (310). 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). 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) can be positioned between the first side (28A) and the second side (28D), and can face each other in the third direction or be positioned on opposite sides. For example, the third side (28C) can connect one end of the first side (28A) and one end of the second side (28B), and the fourth side (28D) can connect the other end of the first side (28A) and the other end of the second side (28B).

[0118] 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 (230A1), a second hole (54B) formed in the fourth side for mounting or arranging the second OIS coil unit (230A2), and a third hole (54C) formed in the lower part (27B) for mounting or arranging the third OIS coil unit (230B). 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.

[0119] 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 each 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).

[0120] 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).

[0121] At least one of the upper and lower ends of the third side (28C) of the first housing (50) may be formed with a guide protrusion (59A, 59B) for guiding the first circuit board (250A). In addition, at least one of the upper and lower ends of the fourth side (28D) of the first housing (50) may be formed with a guide protrusion for guiding the second circuit board (250B). The second side (28B) of the first housing (50) may include at least two grooves (58A, 58B) corresponding to at least two rear protrusions (61C1, 61C2) of the driving plate (61). For example, at least two grooves (58A, 58B) of the first housing (50) may be arranged to be spaced apart in the third direction. A projection or step may also be formed around at least two of the grooves (58A, 58B), and a lubricant may be placed between the rear projections (61C1, 61C2) and the grooves (58A, 58B), and the description of the projection of the holder (30) may be applied or applied accordingly.

[0122] 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), and the protrusion (57) of the first housing (50) may be formed with a first groove (58A) and a second groove (58B) that correspond to, oppose, or overlap the rear protrusions (61C1, 61C2) of the driving plate (61). In another embodiment, the first housing (50) may not include the protrusion (57), and the first groove (58A) and the second groove (58B) may be formed on the second side (28B) (e.g., the inner surface) of the first housing (50).

[0123] For example, the protrusion (57) may include a first portion (57A) protruding from the inner surface of the second side (28B) and a second portion (57B) connecting the first portion (57A) and the lower portion (27B) of the first housing (50). The first groove (58A) and the second groove (58B) of the first housing (50) may be formed on the inner surface (or front surface) of the second portion (57B) of the protrusion (57). In addition, a groove (44A) for arranging or settling a second magnetic body (63) may be formed on the rear surface of the protrusion (57). The description of the shapes of the first and second grooves (36A, 36B) of the holder (30) may be applied or mutatis mutandis to the first and second grooves (58A, 58B) of the first housing (50).

[0124] In an embodiment, by making the shape of the second groove (58B) of the first housing (50) different from the shape of the first groove (58A), the coupling margin between the rear 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 a manufacturing tolerance occurs between the rear protrusions of the driving plate (61) and the first and second grooves of the first housing, the rear 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 second groove (58B), thereby enabling stable OIS operation. In another embodiment, the shapes of the first and second grooves (36A, 36B) may be the same. In Fig. 9b, when the first housing (50) is viewed from the front, the first groove (58A) is located on the left side and the second groove (58B) is located on the right side, but this is not limited to this, and in other embodiments, the first groove (58A) may be located on the right side and the second groove (58B) may be located on the left side.

[0125] For example, an opening (55) for arranging a magnetic support member (64) may be formed in the second side (28B) of the first housing (50). For example, the opening (55) may be in the form of 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, a first through hole (55A) and a second through hole (55B) may be formed in the second side (28B) of the first housing (50).

[0126] 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 magnetic support member (64) may pass through the first through hole (55A) of the first housing (50), and another part of the magnetic support member (64) may pass through the second through hole (55B) of the first housing (50).

[0127] Next, the support (60) will be described.

[0128] The support member (60) is disposed between the holder (30) and the first housing (50) and can support the holder (30) with respect to the first housing (50). The support member (60) can include a mover plate (61) disposed between the holder (30) and the first housing (50). The mover plate (61) can also be expressed as a “mover,” a “tilting guide,” a “mover plate,” a “drive plate,” a “plate,” a “moving plate,” or a “support plate.”

[0129] The driving plate (61) may be disposed between the holder (30) and the first housing (50). For example, the driving plate (61) may be disposed between the second side of the holder (30) and the first housing (50). For example, the driving plate (61) may be disposed between the second side of the holder (30) and the second side (28B) of the first housing (50). The driving plate (61) may include at least two front protrusions (61B1, 61B2) coupled with the holder (30) and at least two rear protrusions (61C1, 61C2) coupled with the first housing (50).

[0130] For example, at least two front protrusions (61B1, 61B2) may be arranged spaced apart in a third direction. Each of the front protrusions (61B1, 61B2) may be arranged in a corresponding one of the first and second grooves (36A, 36B) of the holder (30). In another embodiment, the front protrusions may be arranged spaced apart in a second direction. For example, at least two rear protrusions (61C1, 61C2) may be arranged spaced apart in a second direction (e.g., the Y-axis direction). Each of the rear protrusions (61C1, 61C2) may be arranged in a corresponding one of the first and second grooves (58A, 58B) of the first housing (50). In another embodiment, the rear protrusions may be arranged spaced apart in a third direction. The number of each of the front protrusions and the rear protrusions may be two or more.

[0131] For example, the drive plate (61) may include a body (61A) disposed within a groove (106) of the holder (30), front protrusions (61B1, 61B2) protruding from the front of the body (61A), and rear protrusions (61C1, 61C2) protruding from the rear of the body (61A). For example, the front protrusions (61B1, 61B2) and the rear protrusions (61C1, 61C2) may protrude in opposite directions. For example, each of the front protrusions (61B1, 61B2) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape, but is not limited thereto. In addition, for example, each of the rear protrusions (61C1, 61C2) may have a curved shape, a hemispherical shape, a dome shape, or a polyhedral shape, but is not limited thereto.

[0132] In another embodiment, instead of the front projections, the front surface of the drive plate may have front grooves formed, and instead of the first and second grooves (36A, 36B), the holder may have projections formed for engaging with the front grooves of the drive plate. Also, in another embodiment, instead of the rear projections, the rear surface of the drive plate may have rear grooves formed, and instead of the first and second holes (58A, 58B), the first housing may have projections formed for engaging with the rear grooves of the drive plate.

[0133] 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 may be a magnetic material.

[0134] The support (60) may include a first magnetic body (62) disposed or coupled to the holder (30), and a second magnetic body (63) disposed or coupled to the first housing (50). For example, the support (60) may include a magnetic body support (64) on which the first magnetic body (62) is disposed and coupled to the holder (30). The magnetic body support (64) may be disposed spaced apart from the driving plate (61), and a portion of the magnetic body support (64) may be coupled to the holder (30).

[0135] For example, the magnetic support member (64) may be coupled to the holder (30) by passing through at least a portion of the first housing (50). The magnetic support member (64) may also be expressed as a “support member”, a “mover rigid”, or a “coupling member”.

[0136] Referring to FIGS. 7 to 10, the magnetic support portion (64) may extend from the body (93) and pass through the first housing (50) to be coupled to the holder (30). For example, a portion of the magnetic support portion (64) may pass through the first housing (50) to be coupled to the second side of the holder (30). For example, a portion of the magnetic support portion (64) may pass through the first housing (50) to be coupled to the rear outer surface (31b) of the second side of the holder (30). For example, the magnetic support member (64) may include a body (93) in which a first magnetic body (62) is arranged, 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 to a first coupling groove (105A) of 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 to a second coupling groove (105B) of the holder (30). For example, the first extension member (94a) and the second extension member (94b) may be symmetrical left and right with respect to the body (93). Also, for example, the first extension portion (94a) may be bent from one side (or one end) of the body (93), and the second extension portion (94b) may be bent from the other side (or the other end) of the body (93). For example, the first extension portion (94a) may include a portion that is bent at least once from one side (or one end) of the body (93). For example, the second extension portion (94b) may include a portion that is bent at least once from the other side (or the other end) of the body (93). For example, the extension portions (94a, 94b) may be bent in a direction toward the holder (30) or the optical member (40) with respect to the body (93). For example, the first extension portion (94a) and the second extension portion (94b) each include three bent portions, but in other embodiments, they may include one or two or more bent portions.

[0137] For example, the first extension portion (94a) may include a first portion (94-1) that is bent from one side (or one end) of the body (93), a second portion (94-2) that is bent from the first portion (94-1), and a third portion (94-3) that is bent from the second portion (94-2). For example, the second extension portion (94b) may include a fourth portion (94-4) that is bent from the other side (or the other end) of the body (93), a fifth portion (94-5) that is bent from the fourth portion (94-4), and a sixth portion (94-6) that is bent from the fifth portion (94-5). The third portion (94-3) and the sixth portion (94-6) may be bent in opposite directions. Each of the third portion (94-3) and the sixth portion (94-6) may be parallel to the body (93), but in other embodiments each of the third portion (94-3) and the sixth portion (94-6) may not be parallel to the body (93).

[0138] For example, a groove (64a) may be formed on the front surface of the body (93) of the magnetic support member (64) to allow the first magnetic body (62) to be seated or placed. For example, the first magnetic body (62) may be coupled to the groove (64a) of the magnetic support member (64) by an adhesive. In addition, for example, the extensions (94a, 94b) of the magnetic support member (64) may be coupled to the coupling grooves (105A, 105B) of the holder (30) by an adhesive.

[0139] The second magnetic body (63) may be disposed on the second side (28B) of the first housing (50). For example, the second magnetic body (63) may be disposed on the protrusion (57) of the first housing (50). For example, the second magnetic body (63) may be disposed in the groove (44A) of the protrusion (57) of the first housing (50). For example, the second magnetic body (63) may be coupled to the groove (44a) of the first housing (50) by an adhesive. The magnetic body support (64) is coupled to the holder (30), but may also be expressed as a part of the holder (30). In another embodiment, the magnetic body support (64) may be expressed as an extension extending from the holder (30). In another embodiment, the magnetic body support (64) may be formed integrally with the holder (30).

[0140] The first magnetic body (62) and the second magnetic body (63) may be arranged to face each other or overlap each other in the first direction. The second magnetic body (63) may be arranged between the first magnetic body (62) and the driving plate (61). In the embodiment, the driving plate (61) is not positioned between the first magnetic body (62) and the second magnetic body (63), and since both the first magnetic body (62) and the second magnetic body (64) are arranged on one side of the driving plate (61) with respect to the driving plate (61), the separation distance between the first magnetic body (62) and the second magnetic body (63) can be reduced, thereby increasing the magnetic force (e.g., repulsive force) between the first magnetic body (62) and the second magnetic body (63).

[0141] The driving plate (61) can be pressed against the holder (30) and / or the first housing (50) by the repulsive force between the first and second magnetic bodies (62, 63), and can be brought into close contact with the holder (30) and / or the first housing (50). In an embodiment, since the magnetic force (e.g., repulsive force) between the first magnetic body (62) and the second magnetic body (63) is large, the driving plate (61) can stably support the holder (30), and thus, a stable OIS operation can be performed. Referring to FIG. 13A, the length of the first magnetic body (62) in the second direction can be greater than the length of the second magnetic body (63) in the second direction. In addition, the length of the first magnetic body (62) in the third direction can be greater than the length of the second magnetic body (63) in the third direction. In another embodiment, the length of the first magnetic body (62) in the second direction may be equal to or less than the length of the second magnetic body (63) in the second direction, and the length of the first magnetic body (62) in the third direction may be equal to or less than the length of the second magnetic body (63) in the third direction. For example, the area of ​​the first surface of the first magnetic body (62) facing the second magnetic body (63) may be greater than the area of ​​the first surface of the second magnetic body (63) facing the first magnetic body (62). In another embodiment, the area of ​​the first surface of the first magnetic body may be equal to or less than the area of ​​the first surface of the second magnetic body.

[0142] A repulsive force may be applied between the first magnetic body (62) and the second magnetic body (63). For example, the first magnetic body (62) may include a first magnet. For example, the second magnetic body (63) may include a second magnet that exerts a repulsive force with the first magnet. For example, each of the first magnetic body (62) and the second magnetic body (63) may be a magnet including a north pole and a south pole.

[0143] Also, for example, the first magnetic body (62) may further include a first yoke corresponding to the first magnet and disposed within the groove (64a). For example, the second magnetic body (63) may further include a second yoke corresponding to the second magnet and disposed within the groove (44A) of the first housing (50), and the first yoke and the second yoke may increase a magnetic force (e.g., a repulsive force) acting between the first magnetic body (62) and the second magnetic body (63). For example, the facing surfaces of the first magnetic body (62) and the second magnetic body (63) may have the same polarity (N pole or S pole). In another embodiment, an attractive force may be applied between the first magnetic body and the second magnetic body, in which case the facing surfaces of the first magnetic body and the second magnetic body may have opposite polarities.

[0144] Next, the driving unit (70) will be described.

[0145] The driving unit (70) tilts the holder (30) in the second direction or the third direction or rotates it by a preset angle. The 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 driving unit (70) may include an OIS position sensor unit (240) and a first substrate unit (250).

[0146] The OIS magnet (31) can be placed in the holder (30). For example, the OIS magnet (31) can include a first OIS magnet (31) and a second OIS magnet (32).

[0147] For example, the first OIS magnet (31) 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 the first mounting groove (16A) of the third side (31c) of the holder (30), and the second magnet unit (31B) may be arranged in the first mounting groove (16A) of the fourth side (31d) of the holder (30).

[0148] The second OIS magnet (32) 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).

[0149] 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.

[0150] 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) corresponding to, opposite to, or overlapping the first OIS magnet (31A, 31B) in a third direction, and a second OIS coil (230B) corresponding to, opposite to, or overlapping the second OIS magnet (32) in a second direction. The OIS coil may be alternatively expressed as a “coil” or a coil unit. The OIS magnet may be alternatively expressed as a “magnet” or a “magnet unit.”

[0151] For example, the first OIS coil (230A) may include a first OIS coil unit (230A1) corresponding to, opposite to, or overlapping the first magnet unit (31A) in a third direction, and a second OIS coil unit (230A2) corresponding to, opposite to, or overlapping the second magnet unit (31B) in the third direction. For example, the second OIS coil may include a third OIS coil unit (230B) corresponding to, opposite to, or overlapping the third magnet unit (32) in the second direction.

[0152] For example, the first OIS coil unit (230A1) may be placed on the third side (28C) of the first housing (50) (e.g., the first hole (34A)), the second OIS coil unit (230A2) 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 (230B) may be placed on the lower part (28B) of the first housing (50) (e.g., the third hole (54C)).

[0153] For example, the first OIS coil unit (230A1) may have a closed curve or ring shape including a hollow or hole. The first OIS coil unit (230A1) may be implemented in a coil ring shape that is wound clockwise or counterclockwise with respect to a third axis parallel to the third direction. The second OIS coil unit (230A2) may have a closed curve or ring shape including a hollow or hole. The second OIS coil unit (230A2) may be implemented in a coil ring shape that is wound clockwise or counterclockwise with respect to a third axis parallel to the third direction. The third OIS coil unit (230B) may have a closed curve or ring shape including a hollow or hole. The third OIS coil unit (230B) may be implemented in a coil ring shape that is wound clockwise or counterclockwise with respect to a second axis parallel to the second direction.

[0154] A first electromagnetic force (F21, F22, F31, F32) can be generated by the interaction between the first OIS magnet (31A, 31B) and the first OIS coil (230A1, 230A2). That is, a first electromagnetic force can be generated by the interaction between the first magnet unit (31A) and the first OIS coil unit (230A1) and the interaction between the second magnet unit (31B) and the second OIS coil unit (230A2). For example, a first-first electromagnetic force (F22, F32) may be generated by the interaction between the first magnet unit (31A) and the first OIS coil unit (230A1), a first-second electromagnetic force (F21, F31) may be generated by the interaction between the second magnet unit (31B) and the second OIS coil unit (230A2), and the first electromagnetic force may include the first-first electromagnetic force (F22, F32) and the first-second electromagnetic force (F21, F31).

[0155] In addition, a second electromagnetic force (F1, F2) may be generated by the interaction between the second OIS magnet (32) and the third OIS coil unit (230B). The OIS moving part (e.g., holder (30)) may be tilted about the second axis (e.g., X-axis) by the first electromagnetic force (F21, F22, F31, F32). 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. The OIS moving part may be tilted about the third axis (e.g., Y-axis) by the second electromagnetic force (F1, F2). Here, the third axis (Y-axis) tilting means that the OIS moving part tilts based on the third axis or that the OIS moving part rotates by a preset angle with the third axis as the rotation axis.

[0156] At this time, the OIS movable part may include a holder (30). Alternatively, the OIS movable part may further include a configuration coupled or mounted to the holder (30), for example, an OIS magnet (31A, 31B, 32), a yoke (33), and a magnetic support (64). In addition, the OIS movable part may further include at least one of a driving plate (61) and a first magnetic body (62).

[0157] In addition, the first OIS coil unit (230A1) and the second OIS coil unit (230A2) can overlap in the third direction (Y-axis direction), and 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.

[0158] 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 (230A1, 230A2), 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 (230B).

[0159] The camera device (200) may further include yokes (33: 33A, 33B, 33C) arranged on the OIS magnets (31, 32). For example, the yokes (33) may include a first yoke (33A) arranged on the first magnet unit (31A), a second yoke (33B) arranged on the second magnet unit (31B), and a third yoke (33C) arranged on the third magnet unit (32). For example, the first yoke (33A) may be arranged within the first mounting groove (16A) of the third side (31c) of the holder (30). For example, the first yoke (33A) may be arranged inside the first magnet unit (31A). The second yoke (33B) may be placed within 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 within 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) may increase the first electromagnetic force, and the third yoke (33C) may increase the second electromagnetic force.

[0160] The first substrate portion (250) may be disposed 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). For example, the first OIS coil unit (230A1) and the second OIS coil unit (230A2) may be connected in series with each other, and the first substrate portion (250) may provide the first driving signal to the first and second OIS coil units (230A1, 230A2) that are connected in series. In addition, the first substrate portion (250) may provide the second driving signal to the third OIS coil unit (230B). The first substrate portion (250) may include a first circuit board (250A) disposed on the third side (28C) of the first housing (50), a second circuit board (250B) disposed on the fourth side (28D) of the first housing (50), and a third circuit board (250C) disposed on the lower portion (27B) of the first housing (50).

[0161] In FIG. 5, the first circuit board (250A) appears to be spaced apart from the third circuit board (250C), but the first to third circuit boards (250A to 250C) may be a single integrated board and may be electrically connected to each other. 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. The first circuit board (250A) may be formed with a hole (251A) for engaging with a engaging 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).

[0162] The first OIS coil unit (230A1) may be arranged or mounted on a first surface of the first circuit board (250A), and the plurality of terminals (251) may be arranged on a second surface of the first circuit board (250A). The first surface of the first circuit board (250A) may be a surface facing an outer surface of the third side (28C) of the first housing (50). The second surface of the first circuit board (250A) may be an opposite surface of the first surface of the first circuit board (250A). The first board portion (250) may include a bent portion connecting between the second circuit board (250B) and the third circuit board (250C) and between the first circuit board (250A) and the third circuit board (250C).

[0163] 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 part (28B) of the first housing (50). The second OIS coil unit (230A2) may be arranged or mounted on the first surface of the second circuit board (250B). The first surface of the second circuit board (250B) may be a surface facing the outer surface of the fourth side (28C) of the first housing (50). The third OIS coil unit (230B) may be arranged or mounted on the first surface of the third circuit board (250C). The first surface of the third circuit board (250C) may be a surface facing the outer surface of the lower portion (28B) of the first housing (50).

[0164] 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).

[0165] The camera device (200) may further include a gyro sensor (82) disposed on the first substrate (250). For example, the gyro sensor (82) may be a two-axis, three-axis, or five-axis gyro sensor or an angular velocity sensor.

[0166] The camera device (200) may further include a cover plate (50A) disposed on the second side (28B) of the first housing (50) and covering the opening (55) of the first housing (50). The cover plate (50A) may be coupled or attached to the outer surface of the second side (28B) of the first housing (50) and may prevent foreign substances from entering the first housing (50). A groove (109) may be formed on the outer surface of the second side (28B) of the first housing (50) for arranging or settling the cover plate (50A). In addition, the cover plate (50A) may include a coupling protrusion (51-1) protruding in the second direction or the third direction, and the first housing (50) may include a coupling groove (51-2) for coupling with the coupling protrusion (51-1) of the cover plate (50A). The cover plate (50A) may be formed of a non-magnetic material. For example, the cover plate (50A) may be formed of an injection molded material such as resin or plastic, similar to the first housing (50). In another embodiment, the cover plate (50A) may include a magnetic body or may be formed of a magnetic material. For example, the cover plate (50A) may be a magnetic body plate. When the cover plate (50A) is a magnetic body plate, the magnetic flux of the first magnetic body (62) leaking to the rear of the first magnetic body (62) can be reduced, the magnetic flux generated from the first magnetic body (62) can be concentrated to the second magnetic body (63), and the repulsive force between the first and second magnetic bodies (62, 63) can be increased. This prevents sagging of the drive plate (61), enables the drive plate (61) to stably support the holder (30), enables stable OIS operation, and ensures reliability of OIS operation.

[0167] The OIS position sensor unit (240) can detect the displacement of the OIS movable unit. The OIS position sensor unit (240) can detect the tilted position of the OIS movable unit according to the movement (or tilting) of the OIS movable unit. The OIS position sensor unit (240) detects the position of the OIS movable unit in the second direction and / or the third direction according to the movement of the OIS movable unit, and outputs an output signal according to the detection result. The OIS position sensor unit (240) can be expressed as a “second position sensor unit.”

[0168] The OIS position sensor unit (240) may include a plurality of position sensors.

[0169] For example, the OIS position sensor unit (240) may include a first OIS position sensor (240A) and a second OIS position sensor (240B).

[0170] At least a portion of the first OIS position sensor (240A) 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).

[0171] The first OIS position sensor (240A) can detect the position or displacement of the OIS movable part (e.g., the optical member (40)) tilted with respect to the second axis (e.g., the X-axis). The first OIS position sensor (240A) can detect the position or displacement of the OIS movable part (e.g., the optical member (40)) tilted with respect to the second axis (e.g., the X-axis).

[0172] For example, the first OIS position sensor (240A) may include a first sensor (240A1) disposed or mounted on a first circuit board (250A) and a second sensor (240A2) disposed or mounted on a second circuit board (250B). For example, the first sensor (240A1) may be disposed within a hollow (or hole) of the first OIS coil unit (230A1), and the second sensor (240A2) may be disposed within the hollow (or hole) of the second OIS coil unit (230A2). In another embodiment, the first sensor (240A1) may be disposed outside the hollow (or hole) of the first OIS coil unit (230A1), and the second sensor (240A2) may be disposed outside the hollow (or hole) of the second OIS coil unit (230A2).

[0173] For example, the first sensor (240A1) and the second sensor (240A2) may each be a Hall sensor including first and second input terminals and first and second output terminals. The first and second input terminals of the first sensor (240A1) and the first and second input terminals of the second sensor (240A2) may be connected in parallel. The control unit (810) may supply a driving signal or power to the first and second input terminals of the first and second sensors (240A, 240B) that are connected in parallel.

[0174] The first and second output terminals of the first sensor (240A1) and the first and second output terminals of the second sensor (240A2) can be connected in series, and a first output signal can be output from the series-connected first and second output terminals of the first and second sensors (240A1, 240A2), and the first output signal can be transmitted to the control unit (810).

[0175] In another embodiment, either one of the first sensor (240A1) and the second sensor (240A2) may be omitted, and the control unit (810) may supply a driving signal or power to the first and second input terminals of the remaining one of the first and second sensors (240A, 240B), and a first output signal output from the first and second output terminals of the remaining one of the first and second sensors (240A1, 240A2) may be transmitted to the control unit (810).

[0176] At least a portion of the second OIS position sensor (240B) 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).

[0177] The second OIS position sensor (240B) can detect the position or displacement of the OIS movable part (e.g., the optical member (40)) tilted with respect to the third axis (e.g., the Y axis). The second OIS position sensor (240B) can detect the tilted position or displacement of the OIS movable part with respect to the third axis (e.g., the Y axis).

[0178] For example, the second OIS position sensor (240B) may include a third sensor (240B1) and a fourth sensor (240B2) arranged or mounted on the third circuit board (250C). The third sensor (240B1) and the fourth sensor (240B2) may face or overlap the third OIS magnet (32) in the second direction. For example, the third sensor (240B1) and the fourth sensor (240B2) may be arranged to be spaced apart from each other in the third direction. For example, the third sensor (240B1) and the fourth sensor (240B) may be arranged within the hollow (or hole) of the third OIS coil unit (230B). In another embodiment, the third sensor (240B1) and the fourth sensor (240B) may be arranged outside the hollow (or hole) of the third OIS coil unit (230B).

[0179] For example, the third sensor (240B1) and the fourth sensor (240B2) may each be a Hall sensor including first and second input terminals and first and second output terminals. The first and second input terminals of the third sensor (240B1) and the first and second input terminals of the fourth sensor (240A2) may be connected in parallel. The control unit (810) may supply a driving signal or power to the first and second input terminals of the third and fourth sensors (240B1, 240B2) that are connected in parallel.

[0180] The first and second output terminals of the third sensor (240B1) and the first and second output terminals of the fourth sensor (240B2) 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 (240B1, 240B2), and the second output signal can be transmitted to the control unit (810).

[0181] In another embodiment, either the third sensor (240B1) or the fourth sensor (240B2) may be omitted, and the control unit (810) may supply a driving signal or power to the first and second input terminals of the remaining one of the third and fourth sensors (240B1, 240B2), and a first output signal output from the first and second output terminals of the remaining one of the third and fourth sensors (240B1, 240B2) may be transmitted to the control unit (810).

[0182] In another embodiment, the first OIS position sensor (240A) may be a digital sensor, and the second OIS position sensor (240B) may be a digital sensor. For example, the digital sensor may be a driver IC including a Hall sensor. The digital sensor may transmit or receive data to or from the control unit (810) using data communication using a protocol, such as I2C communication.

FIG. 16b is a perspective view of the body (612) of the second housing (610), FIG. 17a is a first perspective view of the first and second guide parts (614A, 614B) and the lens part (620), FIG. 17b is a second perspective view of the first and second guide parts (614A, 614B) and the lens part (620), and FIG. 18 is an exploded perspective view of the first and second magnets (130A, 130B) and the lens part (620).

[0184] Referring to FIGS. 12 to 18, the first actuator (310) may include a second housing (610), a lens unit (620) disposed within the second housing (610), and a 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).

[0185] The lens unit (620) may be replaced with a “lens assembly.” For example, the lens unit (620) may include a plurality of lens assemblies. In FIGS. 14 to 20 , 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.

[0186] The first actuator (310) may further include a first lens assembly (640) disposed 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. 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). 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).

[0187] 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.

[0188] Also, in another embodiment, one of 640, 622, and 624 may be represented as a “first lens assembly (or first lens group)”, another of 640, 622, and 624 may be represented as a “second lens assembly (or second lens group)”, and the remaining one of 640, 622, and 624 may be represented as a “third lens assembly (or third lens group)”.

[0189] 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.

[0190] 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 have a slight difference depending on the location. In addition, the third lens assembly (624) can perform a position compensation function for the image focused by the variator. For example, the third lens assembly (624) may perform a compensator function that accurately focuses the point imaged by the second lens assembly (622), which is a variable, onto the pixels of the image sensor (540). 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.

[0191] The second housing (610) may be placed 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”. The second housing (610) may be placed inside the cover member (300) and may have a polyhedral (e.g., rectangular parallelepiped) shape having a space therein to accommodate the lens unit (620) and the driving unit (630).

[0192] For example, the second housing (610) may include a body (612) including an upper portion (142A) (or top plate), a lower portion (142B) (or bottom 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). The side portions (141-1 to 141-4) may be alternatively expressed 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 may 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 may be positioned opposite each other.

[0193] A first opening (41A) (or first hole) for exposing one end of the lens unit (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 unit (620) may be formed in the second side (141-2) of the second housing (610). In addition, 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.

[0194] At least one first coupling protrusion (45A) coupled with 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). At least one second coupling protrusion (45B) coupled with 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).

[0195] 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. The first guide portion (614A) may be arranged between the lens portion (620) and the third side portion (141-3), and the second guide portion (614b) may be arranged between the lens portion (620) and the fourth side portion (141-4). 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).

[0196] 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 “home.” 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). 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). At this time, the inner surface of the body (63A) of each of the first and second guide parts (614A, 614B) may be a surface facing the lens part (620). In FIGS. 17A and 17B, one first guide groove (212A) is formed on the lower side of the inner surface of the body (63A) of the first guide part (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 part (614B), but this is not limited thereto. In another embodiment, 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).

[0197] 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). At least one hole (68) may be formed in the protrusions (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) can be coupled with the coupling protrusion (46A) of the body (612) of the second housing (610). For example, the coupling protrusion (46A) can pass through the hole (68) of the protrusion (63B) and be coupled to the first coupling hole (643A) of the third housing (643). At least one coupling protrusion (6A) coupled with the body (612) of the second housing (610) can 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 coupling hole (6B) coupled with the coupling protrusions (6A) of the first and second guide portions (614A, 614B) can be formed on the inner surface of the body (612) of the second housing (610) (see FIG. 18b).

[0198] Referring to FIG. 16B, 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).

[0199] 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). 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.

[0200] 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). 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) can be increased by the first and second openings (67A, 67B).

[0201] In FIGS. 16A and 16B, 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 thereto. 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.

[0202] 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.

[0203] 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). The second lens assembly (622) may include a first lens holder (29) and a second lens array (49) (or second lens group) that is arranged in the first lens holder (29). The lens holder may be replaced with a “bobbin.” The second lens array (49) may include a single lens or a plurality of lenses.

[0204] 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).

[0205] The first side (or first surface) of the first support portion (29B) can be coupled to the first lens barrel (29A). The first support portion (29B) can correspond to, face, or overlap with the body (63A) of the first guide portion (614A) in the third direction. A first mounting portion (30A) for arranging or mounting a first magnet (130A) can be formed on the second side (or second surface) of the first support portion (29B). The second side (or second surface) of the first support portion (29B) can be a surface facing the first guide portion (614A) and can be an opposite surface of the first side (or first surface) of the first support portion (29B).

[0206] For example, the first mounting portion (30A) may include a first mounting surface (11A) formed in an 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. The first support portion (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, be opposite to, or overlap with at least one first guide groove (212A) of the first guide portion (614A). 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.

[0207] 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.

[0208] 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. The distance in the optical axis direction between the second lens group and the third lens group may be varied by the driving unit (630).

[0209] 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).

[0210] The first side (or first surface) of the second support portion (39B) can be coupled to the second lens barrel (39A). The second support portion (39B) can correspond to, face, or overlap with the body (63A) of the second guide portion (614B) in the third direction. A second mounting portion (30B) for placing or mounting a second magnet (130B) can be formed on the second side (or second surface) of the second support portion (39B). The second side (or second surface) of the second support portion (39B) can be a surface facing the second guide portion (614B) and can be an opposite surface of the first side (or first surface) of the second support portion (39B).

[0211] 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).

[0212] 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, oppose, 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 similar to the second groove (13B) of the second support member (30B). 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 moving by the first and second guide grooves (212A, 212B) and the first and second grooves (13A, 13B). As a result, alignment between multiple lens arrays is well achieved, preventing changes in the angle of view or out of focus, and thus significantly improving the image quality or resolution of the camera device (200).

[0213] 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). 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.

[0214] 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 members (614A, 614B) by coming into contact with the cloud members (12A, 12B). For example, the cloud members can 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)). 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 a diameter sufficient to support movement of the lens unit (620).

[0215] Next, the driving unit (630) will be described.

[0216] The driving unit (630) can move the second lens assembly (622) in the first direction and move the third lens assembly (624) in the first direction. For example, the 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. The driving unit (630) can 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) can include a first magnet (130A) disposed in the second lens assembly (622) and a second magnet (130B) disposed in the third lens assembly (624).

[0217] 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). 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.

[0218] The coil (120) may include a first coil (120A) that corresponds to, opposes, or overlaps with the first magnet (130A) in a third direction and is disposed on a third side (142-3) of the second housing (610), and a second coil (120B) that corresponds to, opposes, or overlaps with the second magnet (130B) in the third direction and is disposed on a fourth side (142-4) of the second housing (610). For example, each of the first coil (120A) and the second coil (120B) may have a closed curve or ring shape having a hollow (or hole). For example, each of the first coil (120A) and the second coil (120B) may have a coil ring shape that is wound clockwise or counterclockwise with respect to (or centered on) a third axis that is parallel to the third direction. 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.

[0219] 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).

[0220] 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).

[0221] The driving unit (630) may further include a first yoke (19-1) disposed on the first lens holder (29) and a second yoke (19-2) disposed on 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.

[0222] For example, the first yoke (19-1) may be disposed between the first magnet (130A) and the first lens holder (29), and the second yoke (19-2) may be disposed between the second magnet (130B) and the second lens holder (39). For example, the first yoke (19-1) may be disposed on the first mounting portion (30A) of the first support portion (29B), and the second yoke (19-2) may be disposed on the second mounting portion (30B) of the second support portion (39B).

For example, the second part (19B) may include a 2-1 part supporting one end of the first magnet (130A) and a 2-2 part supporting the other end of the first magnet (130A).

[0223] The driving unit (630) may further include a second substrate portion (190) electrically connected to the first coil (120A) and the second coil (120B).

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.

[0225] 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).

For example, the first sensor (71A) and the second sensor (71B) may be arranged spaced apart from each other in the first direction.

[0233] Each of the first position sensor (71) and the second position sensor (72) may be a digital sensor.

[0238] The first actuator (310) may further include glass (115) positioned in front of the lens portion (620). For example, the glass (115) may be positioned within the second housing (610) to cover the first opening (41A) of the second housing (610), thereby protecting the lens portion (620) and preventing foreign substances from entering the second housing.

[0239] The image sensing unit (330) may include an image sensor (540) that receives and detects light passing through the optical member (40) of the second actuator (320) and the lens assemblies (311, 312, 313) of the first actuator (310) and converts the detected light into an electrical signal.

Each of the first position sensor (71) and the second position sensor (72) may be electrically connected to the first terminal (22A) and the second terminal (22B) of the control unit (810).

[0265] The first position sensor (71) and the second position sensor (72) can be electrically connected to the first terminal (22A) and the second terminal (22B) of the control unit (810) by the wiring, circuit pattern, or conductive layer of the substrate (530, 190, or 250). For example, the substrate (530, 190, or 250) can include a first wiring connecting the first position sensor (71) and the first terminal (22A) of the control unit (810), a second wiring connecting the first position sensor (71) and the second terminal (22B) of the control unit (810), a third wiring connecting the second position sensor (72) and the first terminal (22A) of the control unit (810), and a fourth wiring connecting the second position sensor (72) and the second terminal (22B) of the control unit (810). The first wire and the third wire can be electrically connected to each other, and the second wire and the fourth wire can be electrically connected to each other.

[0266] For example, each of the first position sensor (71) and the second position sensor (72) may include a first terminal electrically connected to a first terminal (22A) of the control unit (810) and a second terminal electrically connected to a second terminal (22B) of the control unit (810).

[0267] For example, in order to identify the first position sensor (71) and the second position sensor (72), different addresses or identification codes may be assigned to each of the first and second position sensors (71, 72). The control unit (810) may perform data communication with the first position sensor (170) and the second position sensor (72) through the different addresses. The first and second signals (DA1, DA2) may be transmitted or received in a time-division manner between the control unit (810) and the first and second position sensors (71, 72) through the first terminal (22A) and the second terminal (22B).

[0268] The second position sensor unit (240) (e.g., 240A) can detect the displacement of the OIS movable unit (e.g., holder (30)) tilted with respect to the second axis (e.g., X-axis) and output a first output signal (HV1). The second position sensor unit (240) (e.g., 240B) can detect the displacement of the OIS movable unit tilted with respect to the third axis (e.g., Y-axis) and output a second output signal (HV2). For example, the first and second output signals (HV1, HV2) can be analog signals.

[0269] 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.

[0270] For example, the storage unit (180) can store a first reference code value (or data) regarding a first output signal (V1) of the first position sensor (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 (V2) of the second position sensor (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. The storage unit (180) may be a separate configuration from the control unit (810), but is not limited thereto, and in another embodiment, the storage unit (180) may be included in the control unit (810).

[0271] 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).

[0272] 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.

[0273] The control unit (810) controls the overall operation of the camera device (200). For example, the control unit (200) can control the first position sensor unit (170) and the second position sensor unit (240) and drive the driving unit (630) and the driving unit (70) to provide an anti-shake function, an auto-focus function, and a magnification adjustment function. For example, the control unit (810) can include at least one of an analog-to-digital converter (ADC), an amplifier, a PID controller, or a memory.

[0274] The control unit (810) may include a digital signal processor (412) that receives a signal (DA1) of a first position sensor (71) and a signal (DA2) of a second position sensor (72).

[0275] The digital signal processor (412) can generate a control signal (SC1) for generating a driving signal (ID1) for driving the first coil (120A) based on a result of comparing the signal (DA1) with a first target value. For example, the first target value may be a reference code value corresponding to a target zoom position of the second lens assembly (622). The digital signal processor (412) can generate a control signal (SC2) for generating a driving signal (ID2) for driving the second coil (120B) based on a result of comparing the signal (DA2) with a second target value. For example, the second target value may be a reference code value corresponding to a target focus position of the third lens assembly (624).

[0276] The control unit (810) may include a first driver (416) that generates a first signal (SK1) based on a control signal (SC1) and generates a second signal (SK2) based on a control signal (SC2). Each of the first signal (SK1) and the second signal (SK2) may be an output signal of the first driver (416).

[0277] Additionally, the control unit (810) may include an amplifier (423) that amplifies the output (SK1, SK2) of the first driver (416). Output terminals of the amplifier (423) may be electrically connected to two terminals (24A, 24B) of the control unit (810). The output of the amplifier (423) may be a driving signal (ID1) or a driving signal (ID2), and the driving signal (ID1) and the driving signal (ID2) may be time-divisionally output through the output terminals (24A, 24B) of the control unit (810).

[0278] Since the signal (DA1) and the signal (DA2) are received by the control unit (810) in a time-division manner, the first driver (416) can generate the first signal (SK1) and the second signal (SK2) in a time-division manner, and the amplifier (423) can output the driving signal (ID1) and the driving signal (ID2) in a time-division manner through two terminals (24A, 24B) of the control unit (810).

[0279] In an embodiment, a driving signal (ID1) for a first coil (120A) and a driving signal (ID2) for a second coil (120B) can be generated using one driver (416) and one amplifier (423). As a result, in the embodiment, the number of drivers and amplifiers required for zoom and AF operations can be reduced, the size of the control unit (810) can be reduced, the size of the camera device can be reduced, and the manufacturing cost of the camera device can be reduced. In addition, since the embodiment can reduce the number of components such as drivers and amplifiers, the power consumed for zoom and AF operations can be reduced.

[0280] The selection unit (245) can receive the driving signal (ID1) and the driving signal (ID2) output from the control unit (810). For example, the selection unit (245) can time-divisionally receive the driving signal (ID1) and the driving signal (ID2) output from the control unit (810).

[0281] The selection unit (245) can supply a driving signal (ID1) to the first coil (120A) and supply a driving signal (ID2) to the second coil (120B). The selection unit (245) can be electrically connected to the output terminals (24A, 24B) of the control unit (810).

[0282] The selection unit (245) may be disposed on any one of the substrate units (530, 190, 250). For example, the selection unit (245) may be disposed on the substrate unit where the control unit (810) is disposed. The selection unit (245) may be electrically connected to the control unit (810). The selection unit (245) may be electrically connected to the terminals (24A to 24C) of the control unit (810) by a wiring, circuit pattern, or conductive layer formed on the substrate unit where the control unit (810) is disposed.

[0283] The selection unit (245) can be electrically connected to two terminals (24A, 24B) of the control unit (810). The selection unit (245) can time-divisionally receive the driving signal (ID1) and the driving signal (ID2), and supply the driving signal (ID1) to the first coil (120A), and supply the driving signal (ID2) to the second coil (120B).

[0284] The selection unit (245) can supply a driving signal (ID1) and a driving signal (ID2) to the first driving unit (e.g., the first coil (120A)) and the second driving unit (e.g., the second coil (230B)) in a time-division manner by a control signal (SW).

[0285] The selection unit (245) can supply the driving signal (ID1) to the first coil (120A) and the driving signal (ID2) to the second coil (120B) based on the control signal (SW). The selection unit (245) can include at least one switch. At least one switch can be switched by the control signal (SW).

[0286] The control unit (810) can output a control signal (SW). The control unit (810) can include at least one terminal (121A) for outputting the control signal (SW). The number of terminals (121A) can be one or two or more.

[0287] For example, a control signal (SW) may be supplied from a digital signal processor (412) to a selection unit (245). The control signal (SW) may be synchronized with the time-division timing of the signals (DA1) and (DA2). For example, during a period (or section) in which the signal (DA1) is input to the control unit (810), the selection unit (245) may electrically connect between the first coil (120A) and the second coil (120B) and the terminals (24A, 24B) of the control unit (810). At this time, the electrical connection between the second coil (120B) and the terminals (24A, 24B) of the control unit (810) may be cut off.

[0288] In addition, for example, during a period (or section) in which a signal (DA2) is input to the control unit (810), the selection unit (245) can electrically connect the second coil (120B) among the first coil (120A) and the second coil (120B) and the terminals (24A, 24B) of the control unit (810). At this time, the electrical connection between the first coil (120A) and the terminals (24A, 24B) of the control unit (810) can be cut off.

[0289] The control unit (810) may include two terminals (24A, 24B) for outputting a driving signal (ID1) and a driving signal (ID2), and the driving signals (ID1, ID2) may be supplied to the selection unit (245) in a time-division manner through the two terminals (24A, 24B).

[0290] The control unit (810) receives an output signal (HV1) of the first OIS position sensor (240A) of the second position sensor unit (240) and an output signal (HV2) of the second OIS position sensor (240B). The control unit (810) may include terminals (23A, 23B) that receive the output signal (HV1) of the first OIS position sensor (240A) of the second position sensor unit (240). The control unit (810) may include terminals (23C, 23D) that receive the output signal (HV2) of the second OIS position sensor (240B) of the second position sensor unit (240).

[0291] The control unit (810) may include an analog-to-digital converter (ADC, 411) that converts output signals (HV1, HV2) into analog-to-digital. The analog-to-digital converter (411) may convert the output signal (HV1) of the first OIS position sensor (240A) into analog-to-digital and generate a first code value (CD1) (or “first digital value”). The analog-to-digital converter (411) may convert the output signal (HV2) of the second OIS position sensor (240B) into analog-to-digital and generate a second code value (CD2) (or second digital value).

[0292] The digital signal processor (412) can generate a control signal (SC3) for generating a driving signal (ID3) to drive the first OIS coil (230A) based on the result of comparing the first code value (CD1) with the third target value. For example, the third target value can be a reference code value (or data) regarding the output of the first OIS position sensor (240A) corresponding to the target second-axis (X-axis) tilting position of the OIS movable part of the second actuator (320).

[0293] The control unit (810) may include a second driver (413) that generates a third signal (SK3) based on a control signal (SC3). In addition, the control unit (810) may include an amplifier (421) that amplifies the output (SK3) of the second driver (413). The output of the amplifier (421) may be a driving signal (ID3). The control unit (810) may supply the driving signal (ID3) to the first OIS coil (230A). The control unit (810) may include terminals (23E, 23F) for outputting the driving signal (ID3).

[0294] The digital signal processor (412) may generate a control signal (SC4) for generating a driving signal (ID4) to drive the second OIS coil (230B) based on a result of comparing the second code value (CD2) with the fourth target value. For example, the fourth target value may be a reference code value (or data) regarding the output of the second OIS position sensor (240B) corresponding to the target third-axis (Y-axis) tilting position of the OIS movable part of the second actuator (320). The reference code values ​​(or data) regarding the outputs of each of the first OIS position sensor (240A) and the second OIS position sensor (240B) may be preset through calibration and stored in the storage unit (180).

[0295] The control unit (810) may include a third driver (414) that generates a fourth signal (SK4) based on a control signal (SC4). In addition, the control unit (810) may include an amplifier (422) that amplifies the output (SK4) of the third driver (414). The output of the amplifier (422) may be a driving signal (ID4). The control unit (810) may supply the driving signal (ID4) to the second OIS coil (230A). The control unit (810) may include terminals (23G, 23H) for outputting the driving signal (ID4).

[0296] In the embodiment of FIG. 20a, the selection unit (245) is separately arranged outside the control unit (810), but in other embodiments, the control unit (810) may be configured to include the selection unit (245), and in this case, the control unit (810) may perform the function of the selection unit (245).

[0297] 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 result of measuring the temperature of the camera device (200). The temperature information of the temperature sensor (566) may be used for temperature compensation for the focusing operation of the third lens assembly (624). For example, the storage unit (180) may store a compensation value corresponding to the temperature information. 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 may be performed in a state (or condition) where the position of the second lens assembly (622) is fixed.

[0298] 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.

[0299] Fig. 21 shows a configuration diagram of a control unit (810) and a selection unit (245) according to another embodiment. In Fig. 21, each of the first OIS position sensor (240A) and the second OIS position sensor (240B) may be a digital sensor, and each of the first position sensor (71) and the second position sensor (72) may be a Hall sensor. The description of the first and second position sensors (71, 72), which are digital sensors in Figs. 20A and 20B, may be applied to or analogized to the first OIS position sensor (240A) and the second OIS position sensor (240B) in Fig. 21. In addition, the description of the first OIS position sensor (240A) and the second OIS position sensor (240B), which are Hall sensors in Figs. 20A and 20B, may be applied to or analogized to the first and second position sensors (71, 72) in Fig. 21.

[0300] The first position sensor (71) can output a first output signal (HV11), and the second position sensor (72) can output a second output signal (HV12). Each of the first output signal (HV11) and the second output signal (HV12) can be an analog signal. The first output signal (HV11) can be input to terminals (123A, 123B) of the control unit (810), and the second output signal (HV12) can be input to terminals (123C, 123D) of the control unit (810).

[0301] The first position sensor (71) can detect the displacement of the second lens assembly (622) and output a first output signal (HV11). The second position sensor (72) can detect the displacement of the third lens assembly (624) and output a second output signal (HV12).

[0302] The first OIS position sensor (240A) can detect the displacement of the OIS movable part (e.g., the holder (30)) tilted with respect to a second axis (e.g., the X-axis) and can output a first data signal (DA11). The second OIS position sensor (240B) can detect the displacement of the OIS movable part tilted with respect to a third axis (e.g., the Y-axis) and can output a second data signal (DA12). The first and second data signals (DA11, DA12) can be transmitted to or received by the control unit (810) using data communication, e.g., I2C. The first and second data signals (DA11, DA12) can be transmitted to or received by the control unit (810) using a clock signal (SCL1) and a data signal (SDA1). For example, the first and second data signals (DA11, DA12) can be transmitted or received to or from the control unit (810) in a time-division manner through the terminals (122A, 122B) of the control unit (810).

[0303] The control unit (810) can generate a driving signal (ID11) for driving the first OIS coil (230A) using the first data signal (DA11), and can generate a driving signal (ID12) for driving the second OIS coil (230B) using the second data signal (DA12).

[0304] The description of the first driver (416) and amplifier (423) of FIG. 20b can be applied or analogized to the first driver (1416) and amplifier (1423) of FIG. 21. The first driver (1416) can generate a first signal (SK11) and a second signal (SK12) in a time-division manner based on control signals (SC1, SC2), and the amplifier (1423) can output a first driving signal (ID11) and a second driving signal (ID12) in a time-division manner through two terminals (124A, 124B) of the control unit (810).

[0305] In addition, the control unit (810) can receive the first and second output signals (HV11, HV12) through the terminals (123A to 123D). The control unit (810) can generate a driving signal (ID13) for driving the first coil (120A) using the first output signal (HV11). The control unit (810) can generate a driving signal (ID14) for driving the second coil (120B) using the second output signal (HV12). The description of the second and third drivers (413, 414) and amplifiers (421, 422) of FIGS. 20A and 20B in relation thereto can be applied or analogized to the second and third drivers (1413, 1414) and amplifiers (1421, 1422) of FIG. 21. In addition, the operation of the control unit (810) related to this can be analogized to the description in FIGS. 20a and 20b.

[0306] In addition, the selection unit (246) of FIG. 21 can time-divisionally receive the first driving signal (ID11) and the second driving signal (ID12) output from the control unit (810). The selection unit (246) can supply the first driving signal (ID11) to the first OIS coil (230A) and the second driving signal (ID12) to the second OIS coil (230B) based on the control signal (SW1). The selection unit (246) can include at least one switch. At least one switch can be switched by the control signal (SW1). The operation of the selection unit (246) and the control signal (SW1) related thereto can be analogized to the description of the selection unit (245) and the control signal (SW) in FIGS. 20A and 20B.

[0307] In a comparative example having one driver IC for zoom and autofocus operations and one driver IC for performing OIS operation for image stabilization, two driver ICs must be driven, which may result in high power consumption, an increase in the size of the camera device, and an increase in manufacturing cost.

[0308] In the embodiment, since a control unit implemented with a single driver IC is used for zoom and autofocus operations and OIS operation for image stabilization, power consumption can be reduced compared to the comparative example, and the size and manufacturing cost of the camera device can be reduced.

[0309] In addition, in the embodiment, a first driving signal (ID11) for the first OIS coil (230A) and a second driving signal (ID12) for the second OIS coil (230B) can be generated using one driver (1416) and one amplifier (1423). As a result, in the embodiment, the number of drivers and amplifiers for OIS operation can be reduced, the size of the control unit (810) can be reduced, the size of the camera device can be reduced, and the manufacturing cost of the camera device can be reduced.

[0310] Fig. 22 shows a configuration diagram of a control unit (810) and selection units (245, 246) according to another embodiment. In Fig. 22, each of the first position sensor (71), the second position sensor (72), the first OIS position sensor (240A), and the second OIS position sensor (240B) may be digital sensors. The description of the first and second position sensors (71, 72), which are digital sensors of Figs. 20A and 20B, may be applied to or analogized to the first and second position sensors (71, 72) of Fig. 22. In addition, the description of the first OIS position sensor (240A) and the second OIS position sensor (240B), which are digital sensors of Fig. 21, may be applied to or analogized to the first and second OIS position sensors (240A, 240B) of Fig. 22.

[0311] Compared with the embodiments of FIGS. 20A and 21, the embodiment of FIG. 22 can reduce the number of terminals of the control unit (810), reduce the number of drivers and amplifiers required for zoom and AF operations, reduce the size of the control unit (810), reduce the size of the camera device, and reduce the manufacturing cost of the camera device. In addition, since the number of parts is reduced in the embodiment, the power consumed for the AF / zoom operation and the OIS operation can be reduced. That is, in the embodiment of FIG. 22, driving signals (ID1, ID2, ID11, ID12) for the AF / zoom operation and the OIS operation can be supplied to the first to fourth driving units (120A, 120B, 230A, 230B) through four terminals (24A, 24B, 124A, 124B) of the control unit (810).

[0312] In FIG. 22, each of the selection unit (245) and the selection unit (246) may be provided with a separate configuration, for example, a separate element (e.g., an integrated device (IC)) or chip, but in another embodiment, the selection unit (245) and the selection unit (246) may be implemented as a single element (e.g., an integrated device (IC)) or a single chip.

[0313] In another embodiment, the selection unit (245) and the selection unit (246) may be implemented to be included in the control unit (810).

[0314] To control high-magnification continuous zoom, the comparative example requires one driver IC for controlling AF and zoom operations and one for OIS operation. Using two driver ICs not only increases cost but also increases the size of the camera device.

[0315] Since the embodiment includes one control unit (e.g., driver IC) that controls AF and zoom operations and OIS operations, the manufacturing cost of the camera device can be reduced and the camera device can be miniaturized.

[0316] FIG. 23 is a block diagram of a camera device (1200) according to another embodiment.

[0317] Referring to FIG. 23, the camera device (1200) may include an actuator (1310). The actuator (1310) may perform an auto-focus and / or zoom function. The actuator (1310) may include at least one lens unit. For example, the actuator (1310) may include a plurality of lens units (1620, 1640). For example, the actuator (1310) may move the lens unit in the optical axis direction to perform an auto-focus and / or zoom function. The camera device (1200) may include an actuator (1320) for performing a shake correction or an optical image stabilizer (OIS) operation. The actuator (1320) may change the path of light. For example, the actuator (1320) may be positioned in front of the actuator (1310). The actuator (1310) may be expressed as “one of the first and second actuators,” and the actuator (1320) may be expressed as “the other one of the first and second actuators.”

[0318] The actuator (1320) may include a fixed portion and a moving portion. The fixed portion of the actuator (1320) may be a fixed element that does not move or tilt in the optical axis direction or in a direction different from the optical axis direction. The moving portion of the actuator (1320) may move or tilt with respect to the fixed portion. For example, the moving portion of the actuator (1320) may include an optical member (1040) for changing the path of light. The moving portion of the actuator (1320) may tilt with respect to a second axis or a third axis, thereby performing image stabilization.

[0319] The optical member (1040) may include a reflector capable of changing the direction of light propagation. For example, the optical member (1040) may be a prism that reflects light, but is not limited thereto, and in other embodiments may be a mirror. The optical member (1040) may change the optical path of incident light into an optical axis parallel to the central axis (Z) of the lens unit, and light passing through the optical member (1040) may pass through a plurality of lens units (1640, 1620) of the actuator (1310) to reach the image sensor (1540), and the image sensor (1540) may detect the same.

[0320] The actuator (1320) may include a driving unit (1630, see FIG. 31) for rotating or tilting a moving unit (e.g., an optical member (1040)) by a preset angle relative to an axis (e.g., an X-axis or a Y-axis) perpendicular to an optical axis direction (e.g., a Z-axis direction). The driving unit (1630) may include a magnet disposed on one of the moving unit and the fixed unit. The driving unit (1630) may include a coil disposed on the other of the moving unit and the fixed unit and generating an electromagnetic force by interaction with the magnet. At this time, the moving unit (e.g., an optical member (1040)) may be rotated or tilted by a preset angle relative to the X-axis or the Y-axis by the interaction between the magnet and the coil.

[0321] The camera device (1200) may include an image sensor (1540). The image sensor (1540) may be positioned at the rear of the actuator (1310). The image sensor (1540) may receive and detect light passing through the optical member (1040) of the actuator (1320) and the lens portions (1640, 1620) of the actuator (1310), and convert the detected light into an electrical signal. The image sensor (1540) may include a sensor area (or imaging area) for detecting light. Here, the sensor area may be expressed as an effective area, a light-receiving area, or an active area. For example, the imaging area may include a plurality of pixels on which an image is formed.

[0322] The actuator (1310) may include a fixed portion and a moving portion. The fixed portion of the actuator (1310) may be a fixed element that does not move or tilt in the optical axis direction and in a direction other than the optical axis direction. The moving portion of the second actuator (1310) may include a lens portion (1620). The moving portion of the second actuator (1310) may include a driving portion (1630, see FIG. 31) for moving the lens portion (1620) in a first direction (e.g., in the optical axis direction or the Z-axis direction). The driving portion (1630) may include a magnet and a coil for moving the moving portion in the first direction.

[0323] The lens unit (1620) may include a plurality of lens units (1622, 1624). In other embodiments, the number of lens units may be one or three or more. The lens unit (1620) may be replaced with a “lens assembly.” The plurality of lens units (1622, 1624) may be arranged in a first direction (e.g., the optical axis direction or the Z-axis direction).

[0324] The actuator (1310) may include a liquid lens portion (1627). The moving portion of the actuator (1310) may include a liquid lens portion (1627). The lens portion (1620) may include a liquid lens portion (1627). The liquid lens portion (1627) may be positioned between the lenses of the lens portions (1622, 1624).

[0325] The lens unit (1620) may include a first lens unit (1622) and a second lens unit (1624). The second lens unit (1624) may be positioned behind the first lens unit (1622). For example, the second lens unit (1624) may be positioned between the first lens unit (1622) and the image sensor (1540).

[0327] The liquid lens unit (1627) can be placed in the first lens unit (1622). The liquid lens unit (1627) can be moved together with the first lens unit (1622).

[0328] Fig. 24 shows one embodiment of the liquid lens portion (1627) of Fig. 1.

[0329] Referring to FIG. 24, the liquid lens unit (1627) may include a liquid lens (1142). The liquid lens unit (1627) may include a plate (1147) for accommodating the liquid lens (1142). The plate (1147) may include a cavity (CA) for accommodating the liquid lens (1142).

[0330] The liquid lens (1142) may include a plurality of different types of liquids (LQ1, LQ2). For example, the liquid lens (1142) may include two or more different liquids.

[0331] The liquids (LQ1, LQ2) do not mix with each other, and an interface (1023) may be formed at the contact portion between the liquids (LQ1, LQ2). For example, a second liquid (LQ2) may be disposed on the first liquid (LQ1). For example, one of the first and second liquids (LQ1, LQ2) may be conductive, and the other of the first and second liquids (LQ1, LQ2) may be non-conductive.

[0332] The liquid lens unit (1627) may include an electrode unit (1044) (or “terminal unit”) for supplying a driving signal to the liquid lens (1142). The electrode unit (1044) may include a plurality of electrodes spaced apart from each other. For example, one of the plurality of electrodes may be a common electrode, and the rest of the plurality of electrodes may be individual electrodes that are independent of each other. A driving signal may be supplied between each of the individual electrodes and the common electrode. A voltage difference between the individual electrode and the common electrode may be a voltage of the driving signal. The number of driving signals may correspond to the number of individual electrodes. For example, a first voltage may be applied to the individual electrodes, and a voltage lower than the first voltage or a ground voltage (0 volts (V)) may be applied to the common electrode. The voltages applied to the individual electrodes may be different voltages. Alternatively, in another embodiment, at least two of the individual electrodes may be applied with the same voltage.

[0333] For example, the liquid lens unit (1627) may include individual electrodes (1045-1 to 1045-n, n being a natural number greater than 1) and a common electrode (1046). In another embodiment, the number of individual electrodes of the liquid lens unit (1627) may be three or more. The liquid lens unit (1627) may include an insulating layer (148) disposed between the individual electrodes (1045-1 to 1045-n) and between the individual electrode (1045) and the common electrode (1046).

[0334] The liquid lens unit (1627) may further include a circuit board (not shown) electrically connected to the electrode unit (1044). The liquid lens unit (1627) may further include a plate (1147) and a plate (1145) disposed on the liquid lens (1142). The plate (1145) may protect the liquid lens (1142) and the individual electrodes (1045) and may prevent foreign substances from entering the liquid lens (1142). In addition, the liquid lens unit (1627) may further include a plate (1146) disposed below the plate (1147) and the liquid lens (1142). The plate (1146) may protect the liquid lens (1142) and the common electrode (1046) and may prevent foreign substances from entering the liquid lens (1142). The plates (1145, 1146) may be formed of a light-transmitting material. The plates (1145, 1146) may be light-transmitting. At least one of the plates (1147, 1145, 1146) may be connected or coupled to the first lens unit (1622). At least one of the plates (1147, 1145, 1146) may be connected or coupled to the first holder (1029).

[0335] An interface (1023) formed between a first liquid (LQ1, e.g., a conductive liquid) and a second liquid (LQ2, e.g., a non-conductive liquid) can be deformed by a driving signal (e.g., a driving voltage) applied to an individual electrode (1045), and the focal length of the liquid lens (1142) can be adjusted by the deformed interface (1023).

[0336] The actuator (1310) may further include a lens unit (1640) positioned between the lens unit (1620) and the actuator (1320). The lens unit (1640) may be a “fixed lens unit” that does not move in the optical axis direction and has a fixed position. Although the lens unit (1640) is expressed as being included in the actuator (1310), it is not limited thereto and may be expressed as not being included in the actuator (1310). In other embodiments, the lens unit (1640) may be omitted.

[0337] Additionally, any one of 1640, 1622, and 1624 may be represented as a “first lens assembly (or first lens group)”, another one of 1640, 1622, and 1624 may be represented as a “second lens assembly (or second lens group)”, and the remaining one of 1640, 1622, and 1624 may be represented as a “third lens assembly” (or third lens group).

[0338] For example, in the embodiment, the lens unit (1640) may be a fixed lens group, and each of the lens units (1622) and the lens units (1624) may include a moving lens group or lens groups. For example, the lens unit (1640) may perform a focus function that focuses parallel light at a specific location. In addition, the lens unit (1622) may perform a variator function that refocuses the image focused by the focus lens unit (1640) at another location. Meanwhile, in the second lens unit (1622), the distance to the subject or the image distance may change significantly, so the magnification may change significantly, and the lens unit (1622), which is a variator, may play an important role in the change in the focal length or magnification of the optical system. Meanwhile, the image point focused by the second lens unit (1622) may slightly differ depending on the location. In addition, the lens unit (1624) may perform a position compensation function for the image focused by the variator. For example, the lens unit (1624) may perform a compensator function that accurately focuses the point imaged by the second lens assembly (1622) onto the pixels of the image sensor (1540). For example, the lens unit (1622) may be a zoom lens unit that performs a zooming function, and the lens unit (1624) may be a focus lens unit that performs a focusing function.

[0339] The actuator (1310) may include a guide portion (1063) for guiding the lens portion (1620) to move in the direction of the optical axis. The guide portion (1063) may extend in the direction of the optical axis. The guide portion (1063) may be in the form of a rail or guide groove extending in the direction of the optical axis. The guide portion (1063) may be provided in the fixing portion. For example, the guide portion (1063) may be disposed within the housing (1612). For example, the guide portion (1063) may be formed in the housing (1612). For example, the guide portion (1063) may be formed integrally with the housing (1612). In another embodiment, the guide portion (1063) may be assembled or coupled with the housing (1612).

[0340] The guide portion (1063) may include a first guide portion (1063A) for guiding the movement of the lens portion (1622) and a second guide portion (1063B) for guiding the movement of the lens portion (1624). To reduce friction between the lens portion (1620) and the guide portion (1063), a ball member or a sliding member may be placed between the lens portion (1620) and the guide portion (1063). The lens portion (1622) may be moved in a first direction along the first guide portion (1063A), and the lens portion (1624) may be moved in the first direction along the second guide portion (1063B).

[0341] For accurate zooming and autofocus operation, the zoom position of the lens unit (1622) and the focus position of the lens unit (1624) must be set considering the distance (or separation distance) between the subject and the camera device (or lens). This setting process is called "calibration" or "zoom calibration." The distance to the subject can be obtained using a distance measuring device (e.g., a laser diode) equipped in the camera device. For example, if the distance between the camera device (or user) and the subject is far, the zoom ratio can be set to a high magnification or changed to a high magnification. On the other hand, if the distance between the camera device and the subject is close, the zoom ratio can be set to a low magnification or changed to a low magnification.

[0342] The stroke or displacement of the lens unit (1620) can be set or changed based on the zoom magnification. The position at which the lens unit (1622) is positioned or moved so as to realize an accurate zoom magnification is referred to as the “zoom position.” In addition, the position, displacement, or stroke of the lens unit (1624) so ​​that the subject is accurately focused at the “zoom position” of the lens unit (1622) is referred to as the “focus position.” Therefore, the focus position can change according to the “zoom position” and distance information to the subject. In order to perform zooming and AF operations, the control unit (1810) or the storage unit (1180) must store data regarding the zoom position and data regarding the focus position corresponding to the zoom position.

[0343] In a camera device having a high-magnification continuous zoom function, the lens parts may be distorted. The distortion of the lens parts may be a distortion of the optical axis (or optical center) of the lens parts. The distortion of the lens part may be defined or determined by the deviation of the optical axis (or optical center) of the lens part. For example, the deviation of the optical axis (or optical center) may mean the degree to which the lens part (or lens) is distorted or tilted with respect to a reference position. For example, the reference position may be a preset position (or coordinate value) at which the optical axis (or optical center) of the lens part (or lens) is aligned with the imaging area of ​​the image sensor (1540) when there is no distortion of the lens part (or lens). For example, the reference position (or preset coordinate value) may be the center (or coordinate value of the center, for example, the origin (0,0)) of the imaging area of ​​the image sensor (1540).

[0344] Ideally, when there is no misalignment (or tilt) of the lens unit (or lens), the optical axis (or optical center) of the lens unit can be aligned with the reference position (or preset coordinate value) of the image sensor (1540). However, when there is misalignment (or tilt) of the lens unit (or lens), the optical axis (or optical center) of the lens unit (or lens) may not be aligned with the reference position of the image sensor (1540), but may be aligned with a first position of the imaging area of ​​the image sensor (1540) that is not the reference position. For example, the amount of deviation or tilt may be a difference between the reference position and the first position. For example, the deviation may be a difference in coordinate values ​​between the reference position and the first position.

[0345] There may be various causes for lens distortion. For example, the cause may be the shape of the lens barrel that accommodates the lens, the shape of the guide portion (e.g., the degree of warpage), or the center distortion due to the installation of lenses included in the lens portion. In particular, since a camera device with a zoom function has a long stroke or movement distance of the zoom lens in the direction of the optical axis, lens distortion may occur due to the shape of the guide portion or the movement of the lens portion. Such lens distortion may cause image distortion or a decrease in resolution.

[0346] In an embodiment, the liquid lens unit (1627) can prevent distortion of an image or reduction in resolution due to misalignment of the lens unit (1622, or 1624). That is, the liquid lens unit (1627) can compensate for the deviation of the optical axis (or optical center) due to misalignment of the lens unit (1622, or 1624). That is, by controlling the driving signal supplied to the liquid lens unit (1627), the interface (1023) of the liquid lens (1142) can be controlled. By controlling the interface (1023), the deviation of the optical axis (or optical center) due to the misalignment of the lens unit can be compensated for or corrected. Accordingly, the embodiment can correct the deviation (or tilt) of the optical axis (or optical center) of the lens unit due to misalignment of the lens unit, prevent distortion of an image, and improve resolution.

The first position sensor unit (1071) may detect displacement or position of the first lens unit (e.g., the first holder (1029)) in the optical axis direction. The first position sensor unit (1071) may detect a magnetic field of the first magnet unit (1130A).

[0372] FIG. 29 is a cross-sectional view of a first actuator (1310) according to another embodiment.

[0373] Referring to FIG. 29, the liquid lens unit (1627) may be disposed in the fixed lens unit (1640).

[0375] FIG. 30 is a drawing for explaining correction of tilt of a lens unit (1620) by a liquid lens unit (1627) according to an embodiment.

[0376] Referring to FIG. 30, due to misalignment of the lens unit (1622), the optical axis (or optical center) of the lens unit (1622) may have a deviation (K1) with respect to the reference position (101). Alternatively, due to misalignment of at least one of the lens unit (1622) and the lens unit (1624), the optical axis (or optical center) of the lens unit (1622) and the optical axis (or optical center) of the lens unit (1624) may not coincide or be aligned, and may be misaligned.

[0377] In an embodiment, the driving signal (VT) supplied to the liquid lens unit (1627) can be adjusted to adjust the interface (1023) of the liquid lens (1142) of the liquid lens unit (1627), and the deviation (K1) can be eliminated or reduced by the adjusted interface (1023). In addition, in an embodiment, the adjusted interface (1023) can compensate for the misalignment of the optical axis (or optical center) between the lens unit (1622) and the lens unit (1624), and align the two. For this compensation, the driving signals (V1 to Vn) can be supplied to each of the individual electrodes (1045-1 to 1045-n, where n is a natural number greater than 1) of the liquid lens unit (1627).

[0378] FIG. 31 is a functional block diagram of a camera device (1200) for driving an actuator (1310) according to an embodiment.

[0379] Referring to FIG. 31, the driving unit (1630) can supply a driving signal for driving the coil units (1120A, 1120B). The liquid lens unit driving unit (1635) can supply a driving signal (VT) for driving the liquid lens unit (1627).

[0380] The storage unit (1180) stores data necessary to operate the camera device (1200). The storage unit (1180) may also be expressed as a "memory." For example, the storage unit (1180) may store information on the zoom position of the lens unit (1622) and the focus position of the lens unit (1624) according to the distance from the subject.

[0381] For example, the storage unit (1180) can store a first reference code value (or data) regarding a first output signal of the first position sensing unit (1071) corresponding to the movement range (or stroke range or displacement) of the lens unit (1622). In addition, the storage unit (1180) can store a second reference code value (or data) regarding a second output signal of the position sensing unit (1072) corresponding to the movement range (or stroke range or displacement) of the lens unit (1624). The first and second reference code values ​​may be values ​​stored in advance in the storage unit (1180) through calibration.

[0382] The control unit (1810) controls the overall operation of the camera device (1200).

[0383] For example, the control unit (1810) can control the camera device (1200) to perform an anti-shake function. The control unit (1810) can control the camera device (1200) to perform a zoom function and an auto-focus function. For example, the control unit (1810) can move the lens unit (1620) in the optical axis direction. The control unit (1810) can move the liquid lens unit (1627) in the optical axis direction.

[0384] The control unit (1810) can control the first position sensor unit (1071) and the second position sensor unit (1072). The control unit (1810) can adjust or control the driving signal supplied to the coil unit (1120A, 1120B) of the driving unit (1630). In addition, the control unit (1810) can adjust or control the driving signal (V1 to Vn) supplied to the liquid lens unit (1627).

[0385] The control unit (1810) can compensate for the misalignment of the lens unit (1620) as follows. The control unit (1810) can control the interface of the liquid lens unit (1627) to correct or compensate for the tilt of the lens unit (1620). The control unit (1810) can control the driving signal (VT) supplied to the liquid lens unit (1627) to correct or compensate for the tilt of the lens unit (1620).

[0386] First, the control unit (1810) can obtain zoom position (or zoom magnification) information. Here, the zoom position (or zoom magnification) information may be the zoom position of the lens unit (1620) supplied based on a user's input or selection. Here, the meaning of 'obtain' may include 'receive,' 'extract,' 'select,' or 'read.'

[0387] The control unit (1810) can obtain information about the driving signal (VT) of the liquid lens unit (1627) corresponding to the zoom position of the lens unit (1622).

[0388] Information about the driving signal (VT) of the liquid lens unit (1627) corresponding to the zoom position of the lens unit (1622) can be stored in the storage unit (1180). At this time, information about the driving signal (VT) of the liquid lens unit (1627) can be preset to correspond to multiple zoom positions of the lens unit (1622) through calibration.

[0389] For example, when the lens unit (1622) is positioned at each of a plurality of zoom positions, a drive signal (VT) of the liquid lens unit (1627) can be set to remove the deviation (K1) of the optical axis (or optical center) of the lens unit (1622) caused by the misalignment of the lens unit (1622) described in FIG. 30 through calibration. The zoom positions can be set in a range from a low magnification (wide) position (e.g., 1x or 3x) to a high magnification position (e.g., 5x). The number of zoom positions can be two or more. The drive signal (VT) of the liquid lens unit (1627) corresponding to each of the zoom positions can be set in advance and stored in the storage unit (1180). When the lens unit (1622) is positioned at the zoom position and the lens unit (1624) is positioned at the focus position corresponding to the zoom position, calibration of the drive signal (VT) of the liquid lens unit (1627) can be performed.

[0390] The liquid lens unit (1627) can be driven by a driving signal (VT) corresponding to the zoom position (or zoom magnification) of the lens unit (1622). That is, the interface (1023) of the liquid lens (1142) of the liquid lens unit (1627) can be dependent on the zoom position (or zoom magnification) of the lens unit (1622). For example, at each zoom position, the shape (or interface (1023)) of the liquid lens (1142) can have a different preset shape by the driving signal (VT).

[0391] The control unit (1810) can adjust the shape of the interface of the liquid lens unit (1627) by using information about the driving signal (VT) set in response to the preset zoom positions (or zoom magnifications) of the lens unit (1622).

[0392] The control unit (1810) can supply a driving signal (V1 to Vn) to the liquid lens unit (1627) using information about the driving signal (VT). For example, the control unit (1810) can supply a driving voltage (V1 to Vn) corresponding to the acquired zoom position (or zoom magnification) to the liquid lens unit (1627).

[0393] The control unit (1810) can control the driving unit to move the lens unit (1622) to the zoom position. In addition, the control unit (1810) can control the driving unit to move the lens unit (644) to the focus position corresponding to the zoom position.

[0394] In an embodiment, the driving voltage of the liquid lens unit (1627) corresponding to each zoom position can be set, and the tilt of the lens unit (1620) at each zoom position can be compensated or corrected.

[0395] In the embodiment, the misalignment of the optical axis (or optical center) between the lens unit (1622) and the lens unit (1624) can be corrected or compensated for at all magnifications for the zoom function, thereby enabling uniform and optimized optical performance at all magnifications.

[0396] In addition, solid lenses (e.g., plastic lenses or glass lenses) cannot be physically deformed, so there is a limit to accurately correcting the misalignment of the optical axis (or optical center) between lens parts.

[0397] On the other hand, the shape of the interface (1023) of the liquid lens (1142) of the liquid lens unit (1627) can be variously changed by a driving signal, and a desired shape can be easily created. Therefore, in the embodiment, the limitations of the above-described physical deformation can be overcome by using the liquid lens (1142), and the distortion of the lens unit (1620) can be accurately and precisely corrected or compensated, thereby further improving the optical performance.

[0398] 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 instrument according to the embodiment may be a mobile phone, a cell 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 photograph may be used.
