BEST MODE

Hereinafter, embodiments of the present disclosure, which may concretely realize the objects described above, will be described with reference to the accompanying drawings.

In the following description of the embodiments, it will be understood that, when each element is referred to as being “on” or “under” another element, it can be directly on or under the other element, or can be indirectly formed such that one or more intervening elements are also present. In addition, when an element is referred to as being “on or under,” “under the element” as well as “on the element” may be included based on the element.

In addition, the relational terms “first,” “second,” “on/upper part/above,” and “under/lower part/below” are used herein only to distinguish between one subject or element and another subject or element without necessarily requiring or involving any physical or logical relationship or sequence between such subjects or elements. Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same parts.

Additionally, the terms “comprises,” “includes,” and “has” described herein should be interpreted not to exclude other elements but to further include such other elements, since the corresponding elements may be inherent unless mentioned otherwise. In addition, the term “corresponding to” described herein may encompass at least one of the meanings of “facing” and “overlapping.”

Hereinafter, a camera device and an optical instrument including the same according to embodiments will be described with reference to the accompanying drawings. For convenience of description, a camera device according to an embodiment will be described using the Cartesian coordinate system (x, y, z), but the embodiments are not limited thereto, and may be described using other coordinate systems. In the respective drawings, the X-axis and the Y-axis may be directions perpendicular to the Z-axis, which is an optical-axis (OA) direction. In addition, the Z-axis direction, which is the optical-axis (OA) direction, may be referred to as a “first direction”, the X-axis direction may be referred to as a “second direction”, and the Y-axis direction may be referred to as a “third direction”. In addition, the Y-axis may be referred to as a “first axis”, and the Y-axis direction may be referred to as a “first-axis direction”. The X-axis may be referred to as a “second axis”, and the X-axis direction may be referred to as a “second-axis direction”. For example, the optical axis direction is a direction of the optical axis or a direction parallel to the optical axis.

In addition, hereinafter, the “terminal” may alternatively be referred to as a pad, an electrode, or a conductive layer.

In addition, hereinafter, the “code value” may alternatively be referred to as data or a digital value.

In addition, the “autofocus function” may be a function of automatically focusing on a subject by moving the lens in the optical-axis direction according to a distance to the subject so that an image sensor obtains a clear image of the subject. The “zoom function” may be a function of photographing a subject while increasing or decreasing the magnification of a distant subject through a zoom lens.

Hereinafter, the “camera device” may alternatively be referred to as a “camera”, a “camera module”, an “image-capturing device”, or a “photographing device”.

FIG. 1 is a perspective view of a camera device 200 according to an embodiment, FIG. 2 is an exploded perspective view of the camera device 200 in FIG. 1, and FIG. 3 is a cross-sectional view of the camera device taken along line AB in FIG. 1.

The first actuator 310 may be referred to as a “second actuator”, and the second actuator 320 may be referred to as a “first actuator”.

In an example, the first actuator 310 may be disposed on the rear end of the second actuator 320 and may be coupled to the second actuator 320.

In addition, the camera device 200 may further include a bracket in order to accommodate the first actuator 310, the second actuator 320, and the image sensing unit 330. The bracket may include a hole or a through-hole formed therein so as to accommodate the first actuator 310, the second actuator 320, and the image sensing unit 330. At least one opening may be formed in a side portion or a side surface of the bracket.

The side plate 302 of the cover member 300 may include at least one protrusion 304 formed thereon so as to be coupled to the at least one opening in the bracket.

FIG. 11 is a perspective view of the first magnetic body, the second magnetic body, the plate, and the magnetic body support part. FIG. 12 is a view for explaining electromagnetic force and movement of the driving plate according to interaction between first to third OIS magnets 31A, 31B, and 32 and first to third coil units 230A to 230C, FIG. 13A is a cross-sectional view of the second actuator 320 taken along line CD in FIG. 4, and FIG. 13B is a cross-sectional view of the second actuator 320 taken along line EF in FIG. 4.

Referring to FIGS. 4 to 13B, the second actuator 320 may include an optical member 40 configured to change an optical path so that light that has passed through the opening 303 in the cover member 300 is introduced into the first actuator 310 and a second driving part 70 configured to rotate the optical member 40 at a predetermined angle in a direction (e.g., X-axis direction or Y-axis direction) perpendicular to the optical-axis direction (e.g., Z-axis direction).

The optical member 40 may include a reflective portion capable of changing the travel direction of light. For example, the optical member 40 may be a prism that reflects light. However, the disclosure is not limited thereto. In another embodiment, the optical member 40 may be a mirror.

The optical member 40 may disposed on the holder 30. The optical member 40 may change the optical path of incident light to the optical axis parallel to the central axis Z of the lens unit to convert the incident light into parallel light, and the parallel light may reach an image sensor 540 through the first lens assembly 640, the second lens assembly 622, and the third lens assembly 624.

Referring to FIG. 5, in an example, the optical member 40 may include an incident surface 8A and an emission surface 8B, and may reflect light incident on the incident surface 81 and emit the light through the emission 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 emission surface 8B. For example, an internal angle between the incident surface 8A and the emission surface 8B may be a right angle.

In addition, for example, each of a first internal angle between the incident surface 8A and the reflective surface 8C and a second internal angle between the emission surface 8B and the reflective surface 8C may be 30 degrees to 60 degrees. For example, each of the first internal angle and the second internal angle may be 45 degrees. However, the disclosure is not limited thereto. In addition, due to change in the optical path by the optical member 40, the thickness of the camera device 200 in a direction perpendicular to the incident surface 8A of the optical member 40 may be reduced, and accordingly, the thickness of a mobile device or a terminal 200A in which the camera device 200 is mounted may be reduced.

In an example, the second actuator 320 may include a first housing 50, a holder 30 disposed in the first housing 50, an optical member 40 disposed in the holder 30, a support part 60 disposed between the holder 30 and the housing 50. The second actuator may include a second driving part 70.

Referring to FIGS. 5 and 6A to 6C, the holder 30 may include a seating part 104 on which the optical member 40 is disposed or mounted. The seating part 104 may have a recess shape and may include a mounting surface 104a (or seating surface) on which the reflective surface 8C of the optical member 40 is disposed. For example, the mounting surface 104a may be an inclined surface inclined with respect to the optical-axis direction.

In an example, an adhesive for attachment of the optical member 40 may be disposed on the mounting surface 104a of the holder 30, and at least one recess 104b for receiving the adhesive may be formed in the mounting surface 104a.

In an example, the holder 30 may include a first opening exposing the incident surface 8A of the optical member 40 and a second opening exposing the emission surface 8B of the optical member 40. In an example, the first opening may be formed in the upper side of the holder 30, and the second opening may be formed in one side surface 31a (front outer surface) of the holder 30 facing the lens assembly (e.g., 640) of the first actuator 310. The emission surface 8B of the optical member 40 mounted in the holder 30 may be disposed so as to face the lens assembly (e.g., 640) of the first actuator 310.

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 height difference from the first surface 18A in the second direction (e.g., X-axis direction). The first surface 18A may be located adjacent to or contiguous with a rear outer surface 31b of the holder 30, and the second surface 18B may be located adjacent to or contiguous with a front outer surface 31a of the holder 30. The second surface 18B may be located below the first surface 18A. In an example, the second surface 18B may be located closer to the lower surface 19 of the holder 30 than the first surface 18A.

Since the second surface 18B has a height difference from the first surface 18A, when the holder 30 is tilted in the second direction (e.g., X-axis direction) or rotated at a predetermined angle, spatial interference between the holder 30 and the first housing 50 may be prevented.

In an example, at least one stopper 38 may be formed on the upper surface (e.g., second surface 18B) of the holder 30. The stopper 38 may be a protrusion or a protruding portion that protrudes upward from the upper surface (e.g., second surface 18B) of the holder 30. In an example, the stopper 38 may be formed on the upper surface of each of first and second side portions of the holder 30. Tilt or rotation of the holder 30 in the second direction may be restricted by the stopper 38. In an 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.

The holder 30 may include first and second side portions (or outer side surfaces) 31c and 31d facing each other or opposite to each other. In an example, the seating part 104 may be located between two side portions 31c and 31d of the holder 30. In an example, the two side portions 31c and 31d may be located opposite each other or located so as to face each other in the third direction (e.g., Y-axis direction).

For example, a front outer surface 31a of the holder 30 is referred to an outer surface of a first side of the holder 30, and a rear outer surface 31b of the holder 30 is referred to an outer surface of a second side of the holder 30. The side portion 31c of the holder 30 is referred to a third side of the holder 30, and the side portion 31d of the holder 30 is referred to a fourth side portion 31d of the holder 30.

Each of the third and fourth side portions 31c and 31d of the holder 30 may include a first outer side surface 19A and a second outer side surface 19B having a height difference from the first outer side surface 19A in the third direction (e.g., Y-axis direction). The first outer side surface 19A may be located adjacent to or contiguous with the rear outer surface 31b of the holder 30, and the second outer side surface 19B may be located adjacent to or contiguous with the front outer surface 31a of the holder 30. The second outer side surface 19B may be located closer to the inner side surface of the holder 30 than the first outer side surface 19A.

Since the second outer side surface 19B of the holder 30 has a height difference from the first outer side surface 19A, when the holder 30 is tilted in the third direction (e.g., Y-axis direction) or rotated at a predetermined angle, spatial interference between the holder 30 and the first housing 50 may be prevented.

In an example, at least one stopper 39A may be formed on the third and fourth side portions (e.g., second outer side surface 19B) of the holder 30. The stopper 39A may be a protrusion or a protruding portion that protrudes from the outer side surface (e.g., second outer side surface 19B) of each of the third and fourth side portions 31c and 31d of the holder 30. Tilt or rotation of the holder 30 in the third direction may be restricted by the stopper 39A. In an example, the protruding height of the stopper 39A from the second outer side surface 19B may be less than or equal to the height difference between the first outer side surface 19A and the second outer side surface 19B.

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 height difference from the first surface 17A in the second direction (e.g., X-axis direction). The first surface 17A may be located adjacent to or contiguous with the front outer surface 31a of the holder 30, and the second surface 17B may be located adjacent to or contiguous with the rear outer surface 31b of the holder 30. The first surface 17A may be located below the second surface 17B. In an example, the second surface 17B may be located 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 height difference from the first surface 17A, when the holder 30 is tilted in the second direction (e.g., X-axis direction) or rotated at a predetermined angle, spatial interference between the holder 30 and a second OIS coil 230C may be prevented.

In an example, at least one stopper 41 may be formed on the lower surface (e.g., second surface 17B) of the holder 30. The stopper 41 may be a protrusion or a protruding portion that protrudes downward from the lower surface (e.g., second surface 17B) of the holder 30. Tilt or rotation of the holder 30 in the second direction may be restricted by the stopper 41. In an example, the protruding length of the stopper 38 from the second surface 17B may be less than or equal to the height difference between the first surface 17A and the second surface 17B of the lower surface 17 of the holder 30.

The holder 30 may include a first seating recess 16A formed therein so as to allow a first OIS magnet 31 to be disposed or seated therein and a second seating recess 16B formed therein so as to allow a second OIS magnet 32 to be disposed or seated therein.

In an example, the first seating recess 16A may be formed in the outer side surface (e.g., first outer side surface 19A) of each of the third and fourth side portions 31c and 31d of the holder 30. For example, the first seating recess 16A may be formed in a shape of a recess depressed in the first outer side surface 19A of each of the third and fourth side portions 31c and 31d of the holder 30.

In an example, the second seating recess 16B may be formed in the lower surface 17 (e.g., second surface 16B) of the holder 30. For example, the second seating recess 16B may be formed in a shape of a recess depressed in the lower surface 17 (e.g., second surface 16B) of the holder 30.

Referring to FIG. 6B, the rear outer surface 31b of the holder 30 may include a first surface 21a, a second surface 21b that is adjacent to or contiguous with the third side portion 31c, and a third surface 21c that is adjacent to or contiguous with the fourth side portion 31d.

When viewed from rear, the first surface 21a may be disposed in the center, the second surface 21b may be disposed on the left of the first surface 21a, and the third surface 21c may be disposed on the right of the first surface 21a.

Each of the second surface 21b and the third surface 21c may have a height difference from the first surface 21a in the first direction (e.g., Z-axis direction). In an example, the first surface 21a may be located closer to the inner side surface of the holder 30 than each of the second surface 21b and the third surface 21c. In an example, the second surface 21b and the third surface 21c may be located on the same plane. Alternatively, in another example, the height difference between the first surface 21a and the second surface 21b may be identical to the height difference between the first surface 21a and the third surface 21c. However, the disclosure is not limited thereto. In another embodiment, the two height differences may be different from each other.

In an example, a recess 106 in which a driving plate 61 is seated or accommodated may be formed in the rear outer surface 31b of the second side portion of the holder 30. For example, the recess 106 may be disposed in the center of the rear outer surface 31b, and may be formed so as to be depressed in the rear outer surface 31b.

The holder 30 may include at least two recesses 36A and 36B formed in the first surface 21a of the rear outer surface 31b thereof so as to correspond to at least two front protrusions 61B1 and 61B2 of the driving plate 61. In an example, the at least two recesses 36A and 36B in the holder 30 may be arranged so as to be spaced apart from each other in the third direction, and may be formed in the bottom surface of the recess 106.

In an example, the holder 30 may include a second recess 36B formed in the first surface 21a of the rear outer surface 31b thereof and a first recess 36A spaced apart from the second recess 36B and located on the right. In another embodiment, the first recess may be located on the right.

In an example, the first recess 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 recess 36A may be different from the area of at least another one of the plurality of side surfaces 1A to 1D of the first recess 36B.

In an example, two side surfaces 1C and 1D of the first recess 36A facing each other in the third direction may be symmetrical to each other and may have the same area. In addition, two side surfaces 1A and 1B of the first recess 36A facing each other in the second direction may be symmetrical to each other and may have the same area.

The first area of each of the side surfaces 1C and 1D of the first recess 36A facing each other in the third direction may be different from the second area of each of the side surfaces 1A and 1D of the first recess 36A facing each other 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.

The description of the shapes of the first and second recesses 36A and 36B in the holder 30 may be equally or similarly applied to the first and second recesses 58A and 58B in the first housing 50.

In the embodiment, since the second recess 58B in the first housing 50 is formed to have a different shape from the first recess 58A, a sufficient coupling margin may be ensured between the rear protrusions 61C1 and 61C2 of the driving plate 61 and the first and second recesses 58A and 58B in the housing 50.

A portion of the magnetic body support part 64 may pass through the first through-hole 55A of the first housing 50, and another portion of the magnetic body support par 64 may pass through the second through-hole 55B of the first housing 50.

Next, the support part 60 will be described.

The support part 60 may be disposed between the holder 30 and the first housing 50, and may support the holder 30 with respect to the first housing 50. The support part 60 may include a driving plate 61 disposed between the holder 30 and the first housing 50. The driving plate 61 may alternatively be expressed as “mover,” “mover plate,” “driving board,” “plate,” “moving plate,” or “support plate.”

In another embodiment, front recesses may be formed in the front surface of the driving plate instead of the front protrusions, and protrusions for engagement with the front recesses of the driving plate may be formed at the holder instead of the first and second recesses 36A and 36B.

In another embodiment, rear recesses may be formed in the rear surface of the driving plate instead of the rear protrusions, and protrusions for engagement with the rear recesses in the driving plate may be formed at the first housing instead of the first and second holes 58A and 58B.

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 metal, e.g., SUS. Further, the driving plate 61 may be non-magnetic. In another embodiment, the driving plate may be magnetic.

The support part 60 may include a first magnetic body 62 disposed on or coupled to the holder 30, a second magnetic body 63 disposed on or coupled to the first housing 40, and a plate 65 disposed on or coupled to the holder 30.

In an example, the support part 60 may include a magnetic body support part 64, on which the first magnetic body 62 is disposed and which is coupled to the holder 30. The magnetic body support part 64 may be disposed to be spaced apart from the driving plate 61, and a portion of the magnetic body support part 64 may be coupled to the holder 30. In an example, the magnetic body support part 64 may pass through at least a portion of the first housing 50 to be coupled to the holder 30. The magnetic body support par 64 may be expressed as “support par”, “mover rigid” or “coupling part.”

In an example, the first extension portion 94a and the second extension portion 94b may be left and right symmetrical 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 other end) of the body 93. In an example, the first extension portion 94a may include a portion that is bent at least once from the one side (or one end) of the body 93. In an example, the second extension portion 94b may include a portion that is bent at least once from the other side (or other end) of the body 93.

In an example, the extension portions 94a and 94b may be bent in a direction toward the holder 30 or the optical member 40 with respect to the body 93. In an example, each of the first extension portion 94a and the second extension portion 94b includes three bent portions, but in other embodiments, it may include one or two or more bent portions.

Referring to FIG. 11, for example, the first extension portion 94a includes a first portion 94-1 bent from one side (or one end) of the body 93, and a second portion 94-2 bent from the first portion 94-1, and a third portion 94-3 bent from the second portion 94-2.

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 another embodiment, each of the third portion 94-3 and the sixth portion 94-6 may not be parallel to the body 93.

Referring to FIGS. 5 and 11, in an example, a recess 64a in which the first magnetic body 62 is seated or disposed may be formed in the front surface of the body 93 of the magnetic body support part 64. In an example, the first magnetic body 62 may be coupled to the recess 64a in the magnetic body support part 64 by means of an adhesive.

Referring to FIG. 9C, the second magnetic body 63 may be disposed on the second side portion 28B of the first housing 50. In an example, the second magnetic body 63 may be disposed on the protruding portion 57 of the first housing 50. In an example, the second magnetic body 63 may be disposed in the recess 44A in the protruding portion 57 of the first housing 50. In an example, the second magnetic body 63 may be coupled to the recess 44A in the first housing 50 by means of an adhesive.

The magnetic body support part 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 part 64 may be expressed as an extension part extending from the holder 30. In another embodiment, the magnetic body support part 64 may be formed integrally with the holder 30.

Referring to FIGS. 13A and 13B, the first magnetic body 62 and the second magnetic body 63 may be disposed so as to face or overlap each other in the first direction.

The plate 65 may be disposed on holder 30. The plate 30 may be disposed outside the first magnetic body 62. For example, the plate 30 may be disposed behind a rear surface of the first magnetic body 62. The rear surface of the first magnetic body 62 may be an opposite surface of the front surface of the first magnetic body 62, which faces the rear surface of the second magnetic body 63. In an example, the first magnetic body 62 may be disposed between the second magnetic body 63 and the plate 30.

The plate 65 may be disposed on the magnetic body support part 64. The plate 65 may be disposed between the first magnetic body 62 and the cover plate 50A.

In an example, the plate 65 may be disposed to be spaced apart from the first magnetic body 62. In another embodiment, the plate 65 may be in contact with the first magnetic body 62. In an example, the front surface of the plate 65 may be disposed on the rear surface of the first magnetic body 62.

In an example, at least a portion of the plate 65 may be disposed to face or overlap the first magnetic body 62 in the first direction. Also, for example, at least a portion of the plate 65 may be disposed to face or overlap the second magnetic body 63 in the first direction. Also, for example, at least a portion of the plate 65 may be disposed to face or overlap the driving plate 61 in the first direction.

The second magnetic body 63 may be disposed between the first magnetic body 62 and the driving plate 61. In the embodiment, the driving plate 61 is not located between the first magnetic body 62 and the second magnetic body 63, and both the first magnetic body 62 and the second magnetic body 63 are disposed on one side of the driving plate 61. Therefore, a spacing distance between the first magnetic body 62 and the second magnetic body 63 may be reduced, and accordingly, magnetic force (e.g., repulsive force) between the first magnetic body 62 and the second magnetic body 63 may be increased.

The plate 65 may serve as a reinforcing member that reinforces the rigidity of the magnetic body support part 64. In addition, the plate 65 can concentrate the magnetic flux generated from the first magnetic body 62 to the second magnetic body 63. A magnetic force (e.g., repulsive force) between the first magnetic body 62 and the second magnetic body 63 can be increased. That is, the plate 65 can reduce the magnetic flux leaking to a rear of the first magnetic body 62, and concentrate the magnetic flux generated from the first magnetic body 62 to the second magnetic body 63.

The driving plate 61 may be pressed against the holder 30 and/or the first housing 50 by the repulsive force between the first and second magnetic bodies 62 and 63, and may be in tight contact with the holder 30 and/or the first housing 50. In the 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 may stably support the holder 30, and accordingly, OIS operation may be stably implemented.

Referring to FIG. 13A, the length of the first magnetic body 62 in the second direction may be longer than the length of the second magnetic body 63 in the second direction. Further, referring to FIG. 13B, the length of the first magnetic body 62 in the third direction may be longer 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 shorter 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 shorter than the length of the second magnetic body 63 in the third direction.

In an example, the area of the first surface of the first magnetic body 62 facing the second magnetic body 63 may be larger 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 smaller than the area of the first surface of the second magnetic body.

Repulsive force may act between the first magnetic body 62 and the second magnetic body 63. In an example, the first magnetic body 62 may include a first magnet. In an example, the second magnetic body 63 may include a second magnet that exerts repulsive force on the first magnet. In an example, each of the first and second magnetic bodies is a magnet including N pole and S pole. In addition, in an example, the first magnetic body 62 may further include a first yoke that corresponds to the first magnet and is disposed in the recess 64a. In an example, the second magnetic body 63 may further include a second yoke that corresponds to the second magnet and is disposed in the recess 44A in the first housing 50. The first yoke and the second yoke may increase magnetic force (e.g., repulsive force) acting between the first magnetic body 62 and the second magnetic body 63.

In an example, the surfaces of the first magnetic body 62 and the second magnetic body 63 facing each other may have the same polarity (N pole or S pole).

In another embodiment, attractive force may act between the first magnetic body and the second magnetic body, and in this case, the surfaces of the first magnetic body and the second magnetic body facing each other may have opposite polarities.

The plate 65 may alternatively be expressed as “reinforcement member”, “reinforcement plate”, “magnetic member”, or “magnetic body plate”.

In an example, the plate 65 may be or include a magnetic body. In an example, the plate 65 may be a magnetic metal plate or may include a magnetic metal plate. In an example, when the plate 65 is a magnetic body or includes a magnetic body, the magnetic force between the first magnetic body 62 and the second magnetic body 63 can be improved. In an example, the plate 65 may include iron, nickel, cobalt, ferrite, or an alloy containing at least one of these. In an example, the plate 65 may include at least one of iron, carbon, manganese, nickel, chromium, cobalt, or tungsten, or may be an alloy containing at least one of these.

In other embodiments, the plate 65 may be non-magnetic. In an example, the plate 65 may be made of a non-magnetic metal material. In another embodiment, the plate 65 may be made of a non-magnetic material. In an example, the plate 65 may include a non-ferrous metal. In an example, the plate 65 may contain any one of aluminum, gold, silver, copper, lead, zinc, or tin, or may be an alloy containing at least one of these.

The plate 65 may be disposed in the holder 30 by an insert injection method. In an example, at least one of the holder 30, the first housing 50, and the magnetic body support part 64 may be formed of an injection-molded material such as plastic or resin.

In an example, the plate 65 may be disposed inside the magnetic body support part 64 using an insert method. In the embodiment, the plate 65 is sealed inside the magnetic body support part 64, but in other embodiments, at least a portion of the plate 65 may be exposed from the magnetic body support part 64. In an example, at least a portion of the plate 65 may be exposed from at least one of the top, bottom, and side surfaces of the magnetic body support part 64.

In another embodiment, rather than the insert injection method, a mounting groove or groove for mounting or placing the plate 65 on the magnetic body support part 64 may be formed, and the plate may be combined with the magnetic body support part 64 by a method of assembling the plate 65 to the magnetic body support part 64.

Referring to FIG. 13A, a length of the plate 65 in the second direction may be greater than or equal to a length of the first magnetic body 62 in the second direction. Also, referring to FIG. 13B, a length of the plate 65 in the third direction may be greater than a length of the first magnetic body 62 in the third direction.

In another embodiment, the length of the plate 65 in the second direction may be equal to or smaller than the length of the first magnetic body 62 in the second direction, and the length of the plate 65 in the third direction may be equal to or smaller than the length of the first magnetic body 62 in the third direction.

In an example, an area of the first surface (eg, front surface) of the plate 65 facing the first magnetic body 62 is an area of the first surface (eg, rear surface) of the first magnetic body 62 facing the plate 65. In another embodiment, the area of the first surface of the plate 65 may be equal to or smaller than the area of the first surface of the first magnetic body.

In an example, a thickness of the plate 65 may be smaller than a thickness of the first magnetic body 62. The thickness of plate 62 may be a distance from the first side (eg, front surface) of plate 65 to the second side (eg, rear surface) of plate 65. In another embodiment, the thickness of the plate 65 may be equal to or greater than the thickness of the first magnetic body 62.

In an example, the plate 65 may include a first part that overlaps the first magnetic body 62 in the first direction and a second part that does not overlap the first magnetic body 62 in the first direction. In an example, the second part of the plate 65 may be positioned to surround the first part of the plate 65.

FIG. 14 shows a cross-sectional view of a second actuator according to a comparative example. In the comparative example of FIG. 14, the plate 65 according to the embodiment is omitted.

Referring to FIG. 14, in the comparative example, a shock absorber 69A such as poron is adhered to the third housing 643 of the first lens assembly 640 of the first actuator to reduce the amount of shock applied to the second actuator due to shock. However, compared to injection molded material, the manufacturing dimensional tolerance of the poron is large, so it is difficult to manage the tolerance of the poron. As a result, the size of the poron may deviate significantly from the normal standard, and the shock absorber 69A may not sufficiently perform its role. This may cause oscillation of the camera module, the reliability of OIS control may deteriorate, and cracks may occur in the second actuator due to impact.

The magnetic body support part 64 may be damaged or cracks may occur in the magnetic body support part 64 due to a collision between the magnetic body support part 64 and the first housing 50 by an external impact. In particular, the extension portions 94a and 94b of the magnetic body support part 64 are damaged or cracks occur in the extension portions 94a and 94b due to a collision between the extension portions 94a and 94b of the magnetic body support part 64 and the first housing 50 (see dotted line in FIG. 14).

In addition, in the comparative example, the repulsive force acting between the first magnetic body 62 and the second magnetic body 63 is weak, so the driving plate 61 may not be in close contact with the first housing 50 and the holder 30 and the sag of the driving plate 61 may occur. Due to this sag of the driving plate 61, the reliability of OIS driving may deteriorate.

The plate 65 may include a material with greater rigidity than the injection-molded material of the magnetic body support part 64 and/or the injection-molded material of the first housing 50, for example, a metal material. Alternatively, the plate 65 may be formed of a material with greater rigidity than the injection-molded material.

Or, in an example, the plate 65 may include a non-magnetic material that has greater rigidity than the injection-molded material. Or, in an example, the plate 65 may be formed of a non-magnetic material that has greater rigidity than the injection-molded material. Or, in an example, the plate 65 may include a magnetic material that has greater rigidity than the injection-molded material. Alternatively, the plate 65 may be formed of a magnetic material that has greater rigidity than the injection-molded material.

In the embodiment, by disposing the plate 65 on the magnetic body support part 64, the rigidity of the magnetic body support part 64 including the plate 65 can be improved, and it is possible to prevent the magnetic body support part 64 from being damaged by impact and to prevent cracks from occurring in the magnetic body support part 64 due to impact.

Additionally, in an embodiment in which the plate 65 includes a magnetic material or is formed of a magnetic material, the plate 65 can reduce the magnetic flux leaking to the rear of the first magnetic body 62 and concentrate the magnetic flux generated from the first magnetic body 62 on the second magnetic body 63, and increase the repulsive force between the first and second magnetic bodies 62 and 63.

In the embodiment, since the magnetic force (e.g., repulsive force) between the first and second magnetic bodies 62 and 63 is increased by the plate 65, the sag of the driving plate 61 can be prevented, and the driving plate 61 can stably support the holder 30, and as a result, stable OIS operation can be performed and reliability of OIS driving can be secured.

FIGS. 11 and 13B, the plate 65 may be disposed on the body 93 of the magnetic body support part 64. In an example, the plate 65 may not be disposed on the extension portions 94a and 94b of the magnetic body support part 64. In an embodiment in which the plate 65 is a magnetic material, such as a magnet, if a portion of the plate 65 is disposed on the extension portions 94a and 94b of the magnetic body support part 64, the magnetic field interference between the plate 65 and the first OIS magnets 31A and 31B may increase since the distance between the plate 65 and the first OIS magnet 31A, 31B decreases. As the interference of the magnetic field between the plate 65 and the first OIS magnets 31A and 31B increases, the reliability of OIS driving may deteriorate and the effect of image stabilization may be reduced.

FIG. 15A is a cross-section of the second actuator 320 including the plate 65-1 according to another embodiment, and FIG. 15B is a perspective view of the plate 65-1 of FIG. 15A.

Referring to 15A and 15B, the plate 65-1 may include a magnetic body portion 65A. The magnetic body portion 65A may face the first magnetic body 62 in a first direction, and at least a portion of the magnetic body portion 65A may overlap the first magnetic body 62 in the first direction. Additionally, at least a portion of the magnetic body portion 65A may overlap the second magnetic body 62 in the first direction.

In an example, the plate 65-1 may include a non-magnetic body portion 65B. The magnetic body portion 65A among the magnetic body portion 65A and the non-magnetic body portion 65B may be located farther from the first OIS magnets 31A and 31B than the non-magnetic body portion 65B.

In an example, the plate 65-1 may include a first non-magnetic body portion 65B1 located on the left side of the magnetic body portion 65A and a second non-magnetic body portion 65B2 located on the right side of the magnetic body portion 65A. The magnetic body portion 65A may be positioned between the first non-magnetic body portion 65B1 and the second non-magnetic body portion 65B2. The magnetic body portion 65A may form a boundary with each of the first non-magnetic body portion 65B1 and the second non-magnetic body portion 65B2.

In an example, the front surface of the magnetic body portion 65A and the front surface of the non-magnetic body portion 65B may be located on the same plane. In an example, the rear surface of the magnetic body portion 65A and the rear surface of the non-magnetic body portion 65B may be located on the same plane.

For example, the length of the magnetic body portion 65A in the second direction may be equal to the length of the non-magnetic body portion 65B in the second direction. Also, in an example, the length of the magnetic body portion 65A in the third direction may be smaller than the length of the non-magnetic body portion 65B in the third direction.

FIG. 15C is a variant example 65-1A of the plate of FIG. 15B.

Referring to FIG. 15C, the plate 65-1A may include a magnetic body portion 65A and a non-magnetic body portion 65B, and the non-magnetic body portion 65B may surround at least a portion of the magnetic body portion 65A. In an example, the non-magnetic body portion 65B may wrap around the magnetic body portion 65A. In an example, the length of the magnetic body portion 65A in the second direction may be smaller than the length of the non-magnetic body portion 65B in the second direction. Also, in an example, the length of the magnetic body portion 65A in the third direction may be smaller than the length of the non-magnetic body portion 65B in the third direction.

Referring to FIGS. 15B and 15C, the magnetic body portion 65A may overlap the first magnetic body 62 in the first direction, and the non-magnetic body portion 65B may not overlap the first magnetic body 62 in the first direction or include a part that does not overlap the first magnetic body 62 in the first direction. In addition, in the embodiments of FIGS. 15B and 15C, the magnetic body portion 65A is disposed farther from the first OIS magnets 31A and 31B than the non-magnetic body portion 65B, so the interference of magnetic field between the first OIS magnets 31A and 31B and the plate 65-1, 65-1A can be reduced. That is, the embodiment of FIGS. 15B and 15B can increase the repulsive force between the first magnetic body 62 and the second magnetic body 63, and at the same time, can reduce the interference of magnetic fields between the first OIS magnets 31A, 31B and the plates 65-1, 65-1A, and thereby the reliability of OIS driving can be further improved.

FIG. 16A is a cross-sectional view of the second actuator 320 according to another embodiment, and FIG. 16B is a perspective view of the plate 65 and the magnetic body plate 65A1 of FIG. 16A.

Referring to 16A and 16B, the plate 65 may include or be a non-magnetic body. That is, the plate 65 may be a non-magnetic body, for example, a non-magnetic metal plate. The plate 65 may serve as a reinforcing member and may serve to increase the rigidity of the magnetic body support part 64.

The second actuator 320 may include a magnetic body plate 65A1 that faces or overlaps the first magnetic body 62 in the first direction. In an example, the magnetic body plate 65A1 may be a metal plate with magnetism. In an example, at least a portion of the magnetic body plate 65A1 may overlap the second magnetic body 63 in the first direction.

The magnetic body plate 65A1 may be disposed between the plate 65 and the first magnetic body 62. The magnetic body plate 65A1 may overlap a portion of the plate 65 in the first direction.

In an example, the plate 65 may include a first part that overlaps the magnetic body plate 65A1 in the first direction and a second part that does not overlap the magnetic body plate 65A1 in the first direction. In an example, the first part of the plate 65 among the first and second parts of the magnetic body plate 65A1 may be located farther from the first OIS coils 31A, 31B than the second portion of plate 65.

The magnetic body plate 65A1 of FIG. 16A may be located between one end and the other end of the plate 65. In another embodiment, when viewed in the first direction or from the front, the magnetic body plate 65A1 may be arranged to be surrounded by the plate 65, as shown in FIG. 15C. That is, the length of the magnetic body plate 65A1 in the second direction may be smaller than the length of the plate 65 in the second direction. Additionally, the length of the magnetic body plate 65A1 in the third direction may be smaller than the length of the plate 65 in the third direction.

The magnetic body plate 65A1 may be in contact with the plate 65. In an example, the magnetic body plate 65A1 may be in contact with the front surface of the plate 65. In another embodiment, the magnetic body plate 65A1 may be arranged to be spaced apart from the plate 65.

Embodiment in FIGS. 16A and 16B can increase the repulsive force between the first magnetic body 62 and the second magnetic body 63 and simultaneously reduce interference of the magnetic field between the first OIS magnets 31A and 31B and the plates 65-1 and 65-1A, and thus the reliability of OIS operation can be further improved.

FIG. 17A is a cross-sectional view of the second actuator 320 according to another embodiment, and FIG. 17B is a perspective view of the driving plate 61 on which the plate 66A of FIG. 17A is disposed.

Referring to FIGS. 17A and 17B, the second actuator 320 may include the plate 66A disposed on the driving plate 61.

The plate 66A may be disposed between the front and rear surfaces of the driving plate 61. At least a portion of the plate 66A may face or overlap the second magnetic body 63 in the first direction. In an example, at least a portion of the plate 66A may overlap the first magnetic body 63 in the first direction. Additionally, at least a portion of the plate 66A may overlap the magnetic body plate 65A1 in the first direction.

In an example, the plate 66A may be or include a magnetic body. For example, the plate 66A may be a magnetic metal plate or may include a magnetic metal plate. In an example, when the plate 66A is a magnetic body or includes a magnetic body, an attractive force may be formed between the plate 66A and the second magnetic body 63, and the magnetic plate 61 can come into close contact with the holder 30 and the first housing 50 due to attractive force, and the driving plate 61 can stably support the holder 30 and thus a stable OIS operation can be performed.

In an example, the plate 66A may be disposed inside the driving plate 61 using an insert method. In the embodiment, the plate 66A is sealed inside the driving plate 61, but in other embodiments, at least a portion of the plate 66A may be exposed from the driving plate 61. In an example, at least a portion of the plate 66A may be exposed from at least one of the top surface, the bottom surface, and the side surface of the driving plate 61.

In another embodiment, instead of using the insert injection method, a mounting groove or groove for mounting or placing the plate 66A at the driving plate 61 may be formed, and the plate 66A and the driving plate 61 may be coupled by assembling the plate 66A to the driving plate 61.

In another embodiment, the plate 66A may be disposed on one of the front surface and the rear surface of the driving plate 61.

In another embodiment, the driving plate 61 may include a magnetic body portion. In an example, a portion of the driving plate 61 may be a magnetic body portion. At this time, the magnetic body portion of the driving plate 61 may face or overlap the second magnetic body 63 in the first direction. Or, in an example, at least a portion of the driving plate 61 may overlap the first magnetic body 63 in the first direction. Or, in an example, the entire driving plate 61 may be a magnetic body.

The length of the plate 66A in the second direction may be greater than or equal to the length of the second magnetic body 63 in the second direction. In another embodiment, the length of the plate 66A in the second direction may be smaller than the length of the second magnetic body 63 in the second direction.

FIG. 18A is a cross-sectional view of the second actuator 320 according to another embodiment, and FIG. 18B is a perspective view of the first housing 50 on which the plate 66B of FIG. 18A is disposed.

Referring to FIGS. 18A and 18B, the second actuator 320 may include a plate 66B disposed in the first housing 50.

The plate 66B may be disposed in front of the second magnetic body 63 disposed on the first housing 50. In an example, the second magnetic body 63 may be disposed between the plate 66B and the first magnetic body 62. In an example, the plate 66B may be disposed on the protrusion 57 of first housing 50. In an example, the plate 66B may be disposed further inside the groove 44 formed in the protrusion 57 of the first housing 50.

At least a portion of the plate 66B may face or overlap the second magnetic body 63 in the first direction. In an example, at least a portion of the plate 66B may overlap the first magnetic body 63 in the first direction. Additionally, at least a portion of the plate 66B may overlap the magnetic body plate 65A1 in the first direction.

For example, the plate 66B may be or include a magnetic body. For example, the plate 66B may be a magnetic metal plate or may include a magnetic metal plate. For example, the plate 66B can reduce the magnetic flux of the second magnetic body 63 leaking to the front of the second magnetic body 63, and concentrate the magnetic flux generated from the second magnetic body 63 to the first magnetic body 62. The repulsive force between the first and second magnetic bodies 62 and 63 can be increased.

In the embodiment, since the magnetic force (e.g., repulsive force) between the first and second magnetic bodies 62 and 63 is increased by the plate 66B, sagging of the driving plate 61 can be prevented, and the driving plate 61 can stably support the holder 30, and as a result, stable OIS operation can be performed and reliability of OIS driving can be secured.

Additionally, an attractive force may be formed between the plate 66B and the first magnetic body 62, and the magnetic body plate 61 may be in close contact with the holder 30 and the first housing 50 due to the attractive force, and the driving plate 61 can stably support the holder 30, and because of this, stable OIS operation can be performed.

For example, the plate 66B may be disposed inside the first housing 50 by an insert method. In the embodiment, the plate 66B is sealed inside the first housing 50, but in other embodiments, at least a portion of the plate 66B may be exposed from the first housing 50. For example, at least a portion of the plate 66B may be exposed from at least one of the top surface, the bottom surface, and the side surface of the first housing 50. In another embodiment, instead of using the insert injection method, a mounting groove or groove for mounting or placing the plate 66B at the first housing 50 may be formed, and the plate 66B and the first housing may be coupled by the method in which the plate 66B is assembled to the first housing 50.

The plates 66A and 66B of FIGS. 17A and 18A may be alternatively expressed as “reinforcement member”, “reinforcement plate”, “magnetic member”, or “magnetic plate”. The plates 66A and 66B of FIGS. 17A and 18A may be applied or analogously applied to the embodiments of FIGS. 13B, 15A, and 16A described above.

FIG. 19A is a cross-sectional view of the second actuator 320 according to another embodiment, and FIG. 19B is a perspective view of the magnetic body support part 64 on which the plate 65-2 of FIG. 19A is disposed.

Referring to FIGS. 19A and 19B, the plate 65-2 may be a variant example of the plate 65 of FIG. 13B. The plate 65-2 may be disposed on the body 93 and the extension portions 94a and 94b of the magnetic body support part 64.

The description of the material of the plate 65 in FIG. 13B can be applied or analogously applied to the plate 65-2 in FIG. 19A.

For example, the plate 65-2 includes a body 5-1 disposed on the body 93 of the magnetic body support part 64, and extension parts 5-2 to 5-5 extending from the body 5-1 and disposed on an extension portion 94a of the magnetic body support part 64. For example, the extension parts 5-2 to 5-5 may be bent from the body 5-1. For example, the extension parts 5-2 to 5-5 may be bent in a direction from the body 5-1 toward the holder 30 or the optical member 40.

For example, the plate 65-2 extends from one side (or one end) of the body 5-1 and includes a first extension part 5-2 and 5-3 disposed on the first extension portion 94a of the magnetic body support part 64 and a second extension part 5-4, 5-5 extending from the other side (or other end) of the body 5-1 and disposed on the second extension portion 94b of the magnetic body support part 64.

For example, the first extension part 5-2 and 5-3 includes a first portion 5-2 bent from one side (or one end) of the body 5-1 and a second portion 5-3 bent from the first portion 5-2.

Also, for example, the second extension part 5-4 and 5-5 includes a first portion 5-4 bent from the other side (or other end) of the body 5-1 and a second portion 5-5 bent from the first portion 5-4. In FIG. 19B, each of the first and second extension portions includes two bent portions, but in another embodiment, each of the first and second extension portions may include one bent portion or three or more bent portions.

For example, the first extension part 5-2 and 5-3 may be disposed at the first and second portions 94-1 and 94-2 of the first extension portion 94a of the magnetic body support part 64. The second extension part 5-4 and 5-5 may be disposed at the fourth and fifth portions 94-4 and 94-5 of the second extension portion 94b of the magnetic body support part 64.

In another embodiment, each of the first and second extension parts of the plate 65-2 may be curved.

Since the plate 65-2 of FIG. 19A is disposed at the extension portions 94a and 94b of the magnetic body support part 64, compared to the embodiment of FIG. 13b, the rigidity of the magnetic body support part 64 can be further increased, and thus as a result, it is possible to more effectively prevent the magnetic body support part 64 from being damaged or cracks occurring due to impact.

FIG. 19C is a cross-sectional view of a second actuator including the plate according to another embodiment.

FIG. 19C may be a variant example of FIG. 19A. The embodiment of FIG. 19C may have a structure in which the second part 5-3 of the first extension portion and the second part 5-5 of the second extension portion of the plate 65-2 of FIG. 19A are omitted.

For example, the first extension portion of the plate 65-3 may be disposed at the first to third portions 94-1 to 94-3 of the first extension portion 94a of the magnetic body support part 64, and the second extension portion of the plate 65-3 may be disposed at the fourth to fifth portions 94-4 to 94-6 of the second extension portion 94b of the magnetic body support part 64.

The first extension portion of the plate 65-3 in FIG. 20 includes the first part 5-2, the second part 5-3, and the third part 5-6 bent from the second part 5-3 and disposed at third portion 94-3 of the magnetic body support part 64. In addition, the second extension portion of the plate 65-3 in FIG. 20 includes the first part 5-4, the second part 5-5, and the third part 5-7 bent from the second part 5-5 and disposed at the sixth portion 94-6 of the magnetic body support part 64. The third part 5-6 of the first extension portion of the plate 65-3 and the third part 5-7 of the second extension portion of the plate 65-3 may be bent in opposite directions.

Compared to FIG. 19A, since the extension portion of the plate 65-3 in FIG. 20 further includes the third parts 5-6 and 5-7, the rigidity of the magnetic body support part 64 can be further increased, thereby as a result, it is possible to more effectively prevent the magnetic body support part 64 from being damaged or cracks occurring due to impact.

FIG. 21a is a cross-sectional view of the second actuator 320 including the plate 65-4 according to another embodiment.

Referring to FIG. 21A, compared to FIG. 13B, the plate 65-4 is arranged in a different position. The plate 65-4 may be disposed, coupled, or attached to the outer peripheral surface of the magnetic body support part 64. For example, the plate 65-4 may be disposed, coupled, or attached to the rear surface of the magnetic body support part 64. For example, a groove for disposing or seating the plate 65-4 may be formed at the rear surface of the magnetic body support part 64. The rear surface of the magnetic body support part 64 may be the opposite side to the front surface of the magnetic body support part 64 on which the first magnetic body 62 is disposed.

For example, the plate 65-4 in FIG. 21A is different only in the position in which it is disposed, and the description of the plate 65 in FIG. 13B can be applied or analogously applied to the plate 65-4 in FIG. 21A.

Descriptions of the embodiments of FIGS. 15A to 15C, 16A, 17A, and 18A may be applied or analogously applied to the embodiment of FIG. 21A.

For example, the plate 65-5 may be disposed, coupled, or attached to the rear surface of the magnetic body support part 64. For example, a groove for disposing or seating the plate 65-5 may be formed at the rear surface of the magnetic body support part 64. The rear surface of the magnetic body support part 64 may be the opposite side of the front surface of the magnetic body support part 64 on which the first magnetic body 62 is disposed.

The plates 65-4 and 65-5 of FIGS. 21A and 21B have the advantage of being easily coupled or attached to the magnetic body support part 64 using an adhesive.

Descriptions of the embodiments of FIGS. 15A to 15C, 16A, 17A, and 18A may be applied or analogously applied to the embodiment of FIG. 21A. Additionally, the description of the embodiment of FIG. 20 may be applied to or analogously applied to FIG. 21B.

The magnetic body portion 65A and the non-magnetic body portion 65B of FIGS. 15B and 15C may be applied or applied to the plates 65-2 to 65-5 according to the embodiments of FIGS. 19B, 20, 21A, and 21B. In this case, the magnetic body portion 65A may be formed at a portion of the body 5-1 of the plates 65-2 to 65-5, and the non-magnetic body portion 65B may be the remaining portion of the body 5-1 of the plates 65-2 to 65-5 and the extension parts 5-2 to 5-5, or 5-2 to 5-7.

Additionally, the magnetic body plate 65A1 of FIG. 16A may be applied or analogously applied to the embodiments of FIGS. 19A, 20, 21A, and 21B. Additionally, the plate 66A in FIG. 17A and the plate 66b in FIG. 18A can be applied or analogously applied to the embodiments of FIGS. 19A, 20, 21A, and 21B.

Next, the second driving part 70 will be described.

The second driving part 70 tilts the holder 30 in the second or third direction or rotates the holder 30 at a predetermined angle.

The second driving part 70 may include an OIS magnet 31 and an OIS coil 230. OIS magnet is alternatively expressed as “magnet” or “magnet unit”. OIS coil is alternatively expressed as “coil” or “coil unit”. In addition, the second driving part 70 may include an OIS position sensor unit 240, and a first board unit 250.

In an example, the magnet 130 may include a first magnet 130A disposed on the second lens assembly 622 and a second magnet 130B disposed on the third lens assembly 624.

In an example, the first magnet 130A may be disposed on the first lens holder 29 of the second lens assembly 622, and the second magnet 130B may be disposed on the second lens holder 39 of the third lens assembly 624.

In an example, the first magnet 130A may be disposed in the first seating portion 30A of the first support part 29B of the first lens holder 29, and the second magnet 130B may be disposed in the second seating portion 30B of the second support part 39B of the second lens holder 39.

For example, each of the first and second magnets 130A and 130B may be a monopolar-magnetized magnet including one N pole and one S pole. In another embodiment, each of the first and second magnets 130A and 130B may be a bipolar-magnetized magnet including two N poles and two S poles.

For example, each of the first coil 120A and the second coil 120B may have a closed curve or ring shape including a cavity (or hole). For example, each of the first coil 120A and the second coil 120B may be formed in a shape of a coil ring wound in the clockwise or counterclockwise direction with respect to (or about) the third axis parallel to the third direction.

In an example, the N pole and the S pole of the first magnet 130A may be disposed so as to face the first coil 120A, and the N pole and the S pole of the second magnet 130B may be disposed so as to face the second coil 120B. In an example, the cavity or the hole in each of the first and second coils 120A and 120B may face the first and second magnets 130A and 130B in the third direction.

Movement of each of the first lens assembly 622 and the second lens assembly 624 may be controlled by controlling the first driving signal and the second driving signal. 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 may be controlled, and accordingly, zooming and autofocus of the camera device 200 may be performed.

Referring to FIG. 18, the first driving part 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 second driving part 70 is configured to move the holder 30 coupled to the optical member 40 so that a path of light incident on the optical member 40 can move on a plane (e.g., XY plane) perpendicular to the first axis (optical axis or Z axis). As a result, the image formed on the image sensor 540 can be moved in the X-axis direction and/or Y-axis direction. That is, by controlling the movement of the holder 30, in the embodiment blurring of the image or shaking of the video due to shaking of the camera device when capturing an image or video due to the user's hand shaking can be corrected.

The first OIS position sensor 240A and 240B can detect the displacement of the holder 30 in the third axis direction and output an output signal according to the detected result. The second OIS position sensor 240C can detect the displacement of the holder 30 in the second axis direction and output an output signal according to the detected result.

The storage unit 180 is configured to store data necessary to operate the camera device 200. The storage unit 180 may be alternatively expressed as “memory.” For example, the storage unit 180 may store information about the zoom position and focus position corresponding to the distance to the subject.

For example, the storage unit 180 may store a first reference code value (or data) corresponding to the first output signal V1 of the first position sensing unit 71 which corresponds to the movement range (or stroke range or displacement) of the second lens assembly 622. In addition, the storage unit 180 may store a second reference code value (or data) corresponding to the second output signal V2 of the second position sensing unit 72 which corresponds 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 previously stored in the storage unit 180 through calibration.

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

For example, the camera device 200 may be accurately focused based on a target position of the second lens assembly 622 and a target position of the third lens assembly 624.

The image sensing unit 330 may include an image sensor 540 that converts light reflected from the 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. Also, for example, the image sensor 540 may further include an image signal processor that performs signal processing on digital signals.

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

The first driver 542 is configured to receive the output signal of the first position sensor unit 170, generate a first code value according to the result of analog-to-digital conversion of the received output signal, and control the driving signal applied to the first coil 120 of the first driving part 630 based on the result of comparing the generated first code value and the 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 second driver 260 is configured to receive the output signal of the first OIS position sensor 240A, 240B of the second position sensor unit 240, generate a second code value according to the result of analog-to-digital conversion of the received output signal, and control the first driving signal applied to the first OIS coils 230A and 230B of the second driving part 70 based on the result of comparing the generated second code value and a second target value.

In addition, the second driver 260 is configured to receive the output signal of the second OIS position sensor 240C of the second position sensor unit 240, generate a third code value according to the result of analog-to-digital conversion of the received output signal, and control the second driving signal applied to the second OIS coil 230C of the second driving part 70 based on the result of comparing the generated third code value and a third target value.

For example, the second target value is a reference code value (or data) corresponding to the output of the first OIS position sensor 240A and 240B which corresponds to a second axis (X-axis) target tilting position of the OIS moving unit of the second actuator 320. Also, for example, the third target value is a reference code value (or data) corresponding to the output of the second OIS position sensor 240C which corresponds to a third axis (Y-axis) target tilting position of the OIS moving unit of the second actuator 320. The reference code value (or data) for the output of each of the first OIS position sensors 240A and 240B and the second OIS position sensor 240C may be set in advance through calibration and stored in the storage unit 180.

The camera device 200 may further include a temperature sensor 566 for temperature compensation. The temperature sensor 566 may output temperature information corresponding to the result of measurement of the temperature of the camera device 200.

The temperature information from the temperature sensor 566 may be used for temperature compensation for focusing operation of the third lens assembly 624. In an example, the storage unit 180 may store a compensation value corresponding to the temperature information.

For example, since the second lens assembly 622, which is responsible for zooming, moves according to the magnification set by the user, it is possible to perform temperature compensation on the third lens assembly 624, which is responsible for autofocus, in a state (or condition) in which the position of the second lens assembly 622 is fixed.

Also, for example, the control unit 810 is configured to 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. Because of this, in the embodiment, an accurate auto-focusing operation reflecting temperature compensation can be performed.
