[0035] In the description of the embodiments, where it is stated that an element is formed "on or under," the term "on or under" includes both cases where two elements are in direct contact with each other and cases where one or more other elements are positioned indirectly between the two elements. Furthermore, when expressed as "on or under," it may include the meaning of a downward direction as well as an upward direction relative to a single element.

[0036] Additionally, relational terms used below, such as “first” and “second,” “upper / superior / above,” and “lower / subordinate / below,” do not necessarily require or imply any physical or logical relationship or order between such entities or elements, and may be used solely to distinguish one entity or element from another. Furthermore, the same reference number indicates the same element through the description of the drawings.

[0037] Furthermore, terms such as "include," "constitute," or "have" as described above, unless specifically stated otherwise, imply that the relevant component may be inherent; therefore, they should be interpreted as allowing for the inclusion of additional components rather than excluding them. Additionally, terms such as "corresponding" as described above may include at least one of the meanings of "opposing" or "overlapping."

[0038] Hereinafter, a camera device according to an embodiment and an optical device including the same will be described as follows with reference to the attached drawings.

In each drawing, the X-axis and the Y-axis may refer to directions perpendicular to the Z-axis, which is the direction of the optical axis (OA). In addition, the Z-axis direction, which is the direction of the optical axis (OA), may be defined as any one of the 'first direction', 'second direction', and 'third direction', the X-axis direction may be defined as any one of the 'first direction', 'second direction', and 'third direction', and the Y-axis direction may be defined as the remaining one of the 'first direction', 'second direction', and 'third direction'.

[0039] Additionally, the X-axis can be defined as either the "first axis" or the "second axis," the X-axis direction can be defined as either the "first axis direction" or the "second axis direction," the Y-axis can be defined as the other of the "first axis" and the "second axis," and the Y-axis direction can be defined as the other of the "first axis direction" and the "second axis direction."

Each of the third sensor (24B1) and the fourth sensor (24B2) may be positioned opposite or overlapped with the second OIS magnet (50) in the optical axis direction and may detect the magnetic field of the second OIS magnet (50). The third and fourth sensors (24B1, 24B2) may be placed on the third substrate (250C) of the circuit board (250) or electrically connected to the third substrate (250C). The third and fourth sensors (24B1, 24B2) may be disposed within the hollow of the second OIS coil (230B). Each of the first to fourth sensors (24A1, 24A2, 24B1, 24B2) may be a Hall sensor.

An opening (303) for exposing the lens of the lens module (400) to external light may be formed in the top plate (302) of the cover member (300).

[0118] The tilting guide portion (60) may be positioned between the sensor base (270) and the base (210). For example, the tilting guide portion (60) may be positioned between the lower surface of the sensor base (270) and the lower surface (214) of the base (210). The tilting guide portion (60) may be expressed as a "moving plate," "mover," "mover plate," "tilt guide," "drive plate," "drive plate," "plate," "rotating plate," "tilting plate," or "support plate." The tilting guide portion (60) may serve to guide the tilt of the OIS moving portion (500).

[0119] The tilting guide portion (60) may be in the form of a plate. The length of the tilting guide portion (60) in a direction perpendicular to the optical axis may be greater than the length of the tilting guide portion (60) in the direction of the optical axis. The tilting guide portion (60) may include an opening (60A) that faces or overlaps with the second OIS magnet (50) or the second OIS coil (230B) in the direction of the optical axis. The opening (60A) may be a through hole that penetrates the tilting guide portion (60) in the direction of the optical axis.

[0120] The opening (60A) can reduce the weight (or mass) of the tilting guide part (60), thereby allowing the camera device (200) to be made lighter. Additionally, the opening (60A) of the tilting guide part (50) can serve as a passage for the magnetic field of the second OIS magnet (50) to reach the second OIS coil (230B), and the electromagnetic force resulting from the interaction between the second OIS magnet (50) and the second OIS coil (230B) can be increased. The size (or area) of the opening (60A) may be larger than the size (or outer area) of the OIS magnet (50) or the size (or outer area) of the second OIS coil (230B).

[0123] The arrangement direction of the grooves (27A, 27B) of the sensor base (270) and the holes (65A, 65B) of the tilting guide part (60) may be the same as the arrangement direction of the first rolling member (36), and the arrangement direction of the holes (66A, 66B) of the tilting guide part (60) and the grooves (55A, 55B) of the base (210) may be the same as the arrangement direction of the second rolling member (37).

[0124] At least a portion of the second OIS magnet (50) may be placed within the opening (60A) of the tilting guide portion (60). The second OIS magnet (50) may overlap with the tilting guide portion (60) in a direction perpendicular to the optical axis direction. This allows the length or height of the camera device (200) in the optical axis direction to be reduced. The opening (60A) of the tilting guide portion (50) may be placed between the holes (65A, 65B) of the first receiving portion (65) of the tilting guide portion (60).

[0127] The first rolling member (36) may include a plurality of balls (B1, B2) arranged in a direction parallel to the second axis (602) or in a first direction (e.g., X-axis direction). In another embodiment, the number of the first rolling members (36) may be one or three or more.

[0128] The second rolling member (37) may be positioned between the tilting guide part (60) and the base (210). The second rolling member (37) may be positioned between the second receiving part (66) of the tilting guide part (60) and the groove (55) of the base (210).

[0129] The second rolling member (37) may include a plurality of balls (B3, B4) arranged in a direction parallel to the first axis (601) or in a second direction (e.g., the Y-axis direction). In another embodiment, the number of the second rolling members (37) may be one or three or more. To reduce friction, a lubricant may be placed in at least one of the groove (27) of the sensor base (270), the first and second receiving portions (65, 66) of the tilting guide portion (60), and the groove (55) of the base (210). The first and second rolling members (36, 37) may be members that perform rolling motion or sliding motion. The rolling members (36, 37) may be replaced with "ball," "ball member," or "ball bearing."

[0130] In another embodiment, the first rolling member (36) may be positioned between the tilting guide part (60) and the base (210), and the second rolling member (37) may be positioned between the sensor base (270) and the tilting guide part (60).

[0131] The tilting guide portion (60) may be positioned below the image sensor (810). Additionally, at least a portion of the tilting guide portion (60) may overlap with the image sensor (810) in the optical axis direction. At least a portion of the tilting guide portion (60) may overlap with the lens module (400) (e.g., a lens) in the optical axis direction.

[0132] The support member (450) may further include a magnetic body (85) disposed in the fixed member (400). The magnetic body (85) may be referred to as a "magnet," "yoke," or "holding magnet." The magnetic body (85) may face or overlap with the second OIS magnet (50) in the optical axis direction. The magnetic body (85) may face or overlap with the hollow (60A) of the tilting guide member (60) in the optical axis direction.

[0133] The magnetic body (85) may be placed on the base (210). The magnetic body (85) may be placed on the third substrate (250C) of the circuit board (250). The magnetic body (85) may be placed in the hollow of the second OIS coil (230B). The magnetic body (85) may be made of a metallic material that adheres to a magnet. The magnetic body (85) may be a magnet. The magnetic body (85) may be represented as a "yoke".

[0134] An attractive force may be applied in the direction of the optical axis between the magnetic body (85) and the second OIS magnet (50). Due to the attractive force acting between the magnetic body (85) and the second OIS magnet (50), the sensor base (270) and the base (210) can press the tilting guide part (60), and the tilting guide part (60) and the first and second rolling members (36, 37) can be in close contact with the sensor base (270) and the base (210). Due to the attractive force between the magnetic body (85) and the second OIS magnet (50), the tilting guide part (60) and the rolling members (36, 37) can stably support the OIS moving part (500) with respect to the fixed part (400), and stable OIS operation can be performed.

[0135] In another embodiment, the first and second rolling members (36, 37) and the first and second receiving portions (65, 66) of the tilting guide portion (60) may be omitted, and instead of the first rolling member (36), the tilting guide portion may include a first projection formed at the position of the first receiving portion (65) and a second projection formed at the position of the second receiving portion (66).

[0136] Referring to FIG. 13, the OIS magnet (40, 50) and the OIS coil (230) can act as a driving unit to tilt the OIS moving part (500). Electromagnetic forces (F1, F2) can be generated by the interaction between the first OIS magnet (40) and the first OIS coil (230A).

[0137] Each of the first magnet unit (40A) and the second magnet unit (40B) may be a two-pole magnet having a North pole and a South pole. For example, the North pole and the South pole of each of the first and second magnet units (40A, 40B) may be distinguished in a first direction (X-axis direction). A driving signal may be supplied to each of the first coil unit (230A1) and the second coil unit (230A2), and a first electromagnetic force (F1) may be generated by the interaction between the first coil unit (230A1) and the first magnet unit (40A), and a second electromagnetic force (F2) may be generated by the interaction between the second coil unit (230A2) and the second magnet unit (40B). For example, the direction of the first electromagnetic force (F1) and the second electromagnetic force (F2) may be the first direction.

[0138] In another embodiment, the N pole and S pole of each of the first magnet unit (40A) and the second magnet unit (40B) may be separated in the direction of the optical axis, and the first and second electromagnetic forces (F1, F2) may be applied in the direction of the optical axis, for example, in the upward direction or the downward direction.

[0139] The OIS moving part (500) can be tilted along the first axis (601) by the first and second electromagnetic forces (F1, F2). The OIS moving part (500) can be tilted along the first axis by the first and second electromagnetic forces (F1, F2). Here, tilting along the first axis may mean that the OIS moving part (500) is tilted with respect to the first axis (601) or that the OIS moving part (500) rotates by a preset angle with the first axis (601) as the axis of rotation. The first axis (601) may be a straight line perpendicular to the optical axis and passing through the balls (B3, B4) of the second rolling member (36). The first axis (601) may pass through the centers of the balls (B3, B4) of the second rolling member (36). For example, the first axis (601) can pass through the optical axis (OA).

[0140] In the embodiment, since the first axis tilt for hand shake correction can be performed by the sum of two electromagnetic forces (F1, F2), the driving force for the first axis tilt can be increased, and as a result, a high compensation angle can be implemented during OIS operation.

[0141] A third electromagnetic force (F3) may be generated by the interaction between the second OIS magnet (50) and the second OIS coil (230B). The second OIS magnet (50) may be a two-pole magnet having a North pole and a South pole. The North pole and the South pole of the second OIS magnet (50) may be separated into a second direction (Y-axis direction). A driving signal may be supplied to the second OIS coil unit (230B). The direction of the third electromagnetic force may be the second direction.

[0142] The driving signals supplied to the first coil unit (230A1), the second coil unit (230A2), and the second OIS coil unit (230B) may be independent of each other. In another embodiment, the first coil unit (230A1) and the second coil unit (230A2) may be connected in series with each other, and a single driving signal may be supplied to the first and second coil units (230A1, 230A2) connected in series.

[0143] In the embodiment, the second OIS magnet (50) may be positioned so as to overlap with the optical axis (OA) or the image sensor (810) in the direction of the optical axis. Additionally, in the embodiment, the second OIS magnet (50) may be positioned so as to overlap with the second axis (602) or the image sensor (810) when viewed in the direction of the optical axis or from above. As a result, in the embodiment, the distance between the second OIS magnet (50) and the second OIS coil (230B) may be positioned close, the driving force for second axis tilting applied to the OIS moving part (500) may be increased, and a high compensation angle may be implemented during OIS operation.

[0144] In another embodiment, at least one of the first magnet unit (40A), the second magnet unit (40B), and the second OIS magnet (50) may be a four-pole magnet comprising two N poles and two S poles.

[0145] Referring to FIG. 12, in the embodiment, the path (RW) may be extended in the optical axis direction or downward direction to increase the stroke section of the bobbin (110) in the optical axis direction. The path (RW) may be a section in which the rolling member (21) can move in the optical axis direction or a section in which it can slide in the optical axis direction. The path (RW) may be expressed as a "raceway." For this extension, in the embodiment, a groove (114) may be formed in the protrusion (113) of the bobbin (110), and a groove (224) may be formed in the protrusion (146) of the housing (140).

[0146] The path (RW) may be the maximum range in which the rolling member (210) can move in the direction of the optical axis. Alternatively, the path (RW) may be the range from the top of the groove (113) of the bobbin (110) (or the groove (224) of the housing (140)) to the bottom of the groove (113) of the bobbin (110) (or the groove (224) of the housing (140)). Alternatively, the path (RW) may be the range between the center of the uppermost ball (b1) among the ball members (b1, b2, b3, b4) of the rolling member (21) and the center of the lowermost ball (b4) among the ball members (b1, b2, b3, b4). Alternatively, the path (RW) may be a range between the top of the uppermost ball (b1) among the ball members (b1, b2, b3, b4) of the cloud member (21) and the bottom of the lowermost ball (b4) among the ball members (b1, b2, b3, b4).

[0147] In the embodiment, since the path (RW) is increased, an escape hole (18) for escape may be formed in the lower part (214) of the base (210) to prevent spatial interference between the housing (140), the bobbin (110), and the base (210) when driving the OIS.

[0148] To reduce the size (or length) of the camera device (200) in the direction of the optical axis, the image sensor (810) may be positioned higher than the bottom or bottom side of the path (RW). Additionally, to reduce the size (or length) of the camera device (200) in the direction of the optical axis, the position of the image sensor (810) in the direction of the optical axis may be located within the path (RW).

[0149] To reduce the size (or length) of the camera device (200) in the direction of the optical axis, the image sensor (810) may be positioned higher than the bottom or lower surface of the protrusion (146) of the housing (140). For example, the image sensor (810) may be positioned higher than the bottom of the groove (224) of the housing (140). For example, the image sensor (810) may overlap with the path (RW) in a direction perpendicular to the optical axis (or direction of the optical axis). The lower surface of the image sensor (810) may be positioned higher than the bottom of the second extension of the housing (140).

[0150] Additionally, the first substrate (801) of the circuit board (800) may be positioned higher than the bottom or bottom side of the path (RW). The first substrate (801) of the circuit board (800) may be positioned higher than the bottom or bottom surface of the protrusion (146) of the housing (140). For example, the first substrate (801) may be positioned higher than the bottom of the groove (224) of the housing (140). For example, the first substrate (801) may overlap with the path (RW) in a direction perpendicular to the optical axis (or optical axis direction). The bottom surface of the first substrate (801) may be positioned higher than the bottom of the second extension of the housing (140).

[0151] Additionally, the sensor base (270) may be positioned higher than the bottom or lower side of the path (RW). The sensor base (270) may be positioned higher than the bottom or lower surface of the protrusion (146) of the housing (140). For example, the sensor base (270) may be positioned higher than the bottom of the groove (224) of the housing (140). For example, the sensor base (270) may overlap with the path (RW) in a direction perpendicular to the optical axis (or optical axis direction). The lower surface of the sensor base (270) may be positioned higher than the bottom of the second extension of the housing (140).

[0152] Additionally, the second OIS magnet (50) (or yoke (51)) may be positioned higher than the bottom or lower surface of the protrusion (146) of the housing (140). For example, the second OIS magnet (50) (or yoke (51)) may be positioned higher than the bottom of the groove (224) of the housing (140). For example, the second OIS magnet (50) (or yoke (51)) may overlap with the path (RW) in a direction perpendicular to the optical axis (or optical axis direction). The lower surface of the OIS magnet (50) may be positioned higher than the bottom of the second extension of the housing (140).

[0153] Additionally, for example, at least one lower surface of the image sensor (810), the first substrate (801), the sensor base (270), and the second OIS magnet (50) (or yoke (51)) may be positioned higher than the lower surface (or lower surface) of the protrusion (146) of the housing (140) or the lower surface of the groove (224) of the housing (140) in a direction perpendicular to the optical axis (or optical axis direction).

[0154] The position of the image sensor (810) in the direction of the optical axis may be lower than the midpoint (H1) of the path (RW). For example, the top surface of the image sensor (810) may be lower than the midpoint (H1) of the path (RW). The midpoint (H1) of the path (RW) may be halfway point of the path (RW). That is, the bottom surface of the image sensor (810) may be higher than the bottom of the path (RW) and lower than the midpoint (H1) of the path (RW).

[0155] In addition, the relative position between the bobbin (110) and the image sensor (810) according to the movement of the bobbin (110) in the direction of the optical axis may be as follows.

[0156] When the bobbin (110) is positioned at the lowest side in the optical axis direction, the lower surface of the image sensor (810) may be positioned higher than the lower surface (or lowest side) of the bobbin (110). When the bobbin (110) is positioned at the highest side in the optical axis direction, the lower surface of the image sensor (810) may be positioned higher than the lower surface of the bobbin (110) or at the same height. In another embodiment, when the bobbin (110) is positioned at the highest side in the optical axis direction, the upper surface of the image sensor (810) may be positioned lower than the lower surface (or lowest side) of the bobbin (110).

[0157] In a camera device (hereinafter "Comparative Example 1") in which the image sensor is fixed and the lens is moved in a direction perpendicular to the optical axis for shake correction or image stabilization, image distortion may occur. Additionally, in a camera device ("Comparative Example 2") in which the lens is fixed without moving but the image sensor is moved or tilted for shake correction, image distortion may occur at the edges or corners of the image sensor. As such, in Comparative Example 1 and Comparative Example 2, the image sensor and the lens are separated, and only one of the image sensor or the lens moves or tilts, so image distortion may occur during shake correction, and high-angle shake correction may be difficult.

[0158] In the embodiment, since the OIS moving unit (500) includes a lens module (400) and an image sensor (810), when driving OIS, the tilt direction (or rotation direction) and tilt angle (or rotation angle) of the lens module (400) (or bobbin (110)) may be the same as or nearly the same as the tilt direction (or rotation direction) and tilt angle (or rotation angle) of the image sensor (810).

[0159] In the embodiment, when OIS is operated, the lens module (400) (or bobbin (110)) and the image sensor (810) can be tilted or rotated together, and there is no distortion of the image and 100% image resolution can be obtained, and high-angle shake correction or vibration correction can be achieved.

[0160] In addition, in the embodiment, when OIS is operated, the lens module (400) (or bobbin (110)) and the image sensor (810) are tilted or rotated together, so high-bandwidth shake correction is possible. Also, in the embodiment, since mechanical distortion-free image correction is possible, the load received during image processing is low compared to Comparative Example 1 and Comparative Example 2, so current consumption can be reduced.

[0161] In addition, the camera device (200) according to the embodiment may be included in an optical instrument that aims to increase the visual acuity of the eye by using light characteristics such as reflection, refraction, absorption, interference, and diffraction to form an image of an object in space, or to record and reproduce an image by a lens, or to perform optical measurement, propagation or transmission of an image, etc. For example, the optical instrument according to the embodiment may be a mobile phone, mobile phone, smartphone, portable smart device, digital camera, laptop computer, digital broadcasting terminal, PDA (Personal Digital Assistants), PMP (Portable Multimedia Player), navigation, etc., but is not limited thereto, and any device for taking images or photos is possible.

[0162] FIG. 14 shows a perspective view of an optical device (200A) according to an embodiment, and FIG. 15 shows a configuration diagram of the optical device (200A) shown in FIG. 14.

[0163] Referring to FIGS. 14 and 15, the optical device (200A) may include a body (850), a wireless communication unit (710), an A / V input unit (720), a sensing unit (740), an input / output unit (750), a memory unit (760), an interface unit (770), a control unit (780), and a power supply unit (790).

[0164] The body (850) is in the form of a bar, but is not limited thereto, and can be of various structures such as a slide type, folder type, swing type, swivel type in which two or more sub-bodies are combined to move relative to each other.

[0165] The wireless communication unit (710) may be configured to include one or more modules that enable wireless communication between the terminal (200A) and the wireless communication system or between the terminal (200A) and the network where the terminal (200A) is located. For example, the wireless communication unit (710) may be configured to include a broadcast reception module (711), a mobile communication module (712), a wireless internet module (713), a short-range communication module (714), and a location information module (715).

[0167] The camera (721) may include a camera device (200) according to an embodiment. Although FIG. 13 illustrates one camera, in other embodiments, multiple cameras may be provided.

[0168] The camera (721) of FIG. 14 may be a front camera in which the lens module (400) of the camera device (200) is positioned to face the front of the body (850) of the optical device (200A), but the optical device according to another embodiment may include a rear camera. The rear camera may include the camera device (200) according to the embodiment, and the lens module (400) of the camera device (200) is positioned to face the rear of the body (850) of the optical device (200A). In another embodiment, the camera device (200) may be included in both the front camera and the rear camera of the optical device (200A).

[0169] The sensing unit (740) can detect the current state of the terminal (200A), such as the open / closed state of the terminal (200A), the location of the terminal (200A), whether there is user contact, the orientation of the terminal (200A), and the acceleration / deceleration of the terminal (200A), and generate a sensing signal to control the operation of the terminal (200A). For example, if the terminal (200A) is in the form of a slide phone, it can sense whether the slide phone is open / closed. In addition, it is responsible for sensing functions related to whether power is supplied by the power supply unit (790) and whether an external device is connected to the interface unit (770).
