[0003] This section provides background information related to the present invention, but it is not necessarily prior art.

[0004] With the widespread use of various mobile terminals and the commercialization of wireless internet services, consumers' needs related to mobile terminals have also diversified to allow various types of peripheral devices to be installed on mobile terminals.

[0005] Among the representative peripheral devices, camera modules for capturing subjects in images or videos are mentioned. These camera modules typically include two types: one is an AF (Auto Focus) camera module, equipped with an AF function that automatically adjusts the focus in response to the distance to the subject; the other is an OIS (Optical Image Stabilization) camera module, equipped with an OIS function that corrects for user hand shake during shooting.

[0006] Recently, rapid research has been conducted on dual-camera modules in which an AF camera module and an OIS camera module are arranged in parallel. However, the dual-camera module has the following drawback: the magnet of the OIS camera module is disconnected from its normal position due to the influence of the magnet of the AF camera module.

[0007] In addition, there are many examples where peripheral devices, such as receivers inside optical devices, are located near dual-camera modules, and the peripheral devices experience problems receiving signals due to EMI (electromagnetic interference) generated by the dual-camera modules. Summary of the Invention

Furthermore, exemplary embodiments of the present invention provide a dual-camera module configured to prevent the generation of EMI (electromagnetic interference). Additionally, exemplary embodiments of the present invention provide an optical device including the aforementioned dual-camera module.

[0095] A dual-camera module according to an exemplary embodiment of the present invention may include a first camera module 1000 and a second camera module 2000.

[0096] The first camera module 1000 may be an AF-driven camera module. In this case, the first camera module 1000 may be referred to as an "AF camera module". Alternatively, the first camera module 1000 may be equipped with an OIS-driven camera module.

[0097] The first camera module 1000 may include a first lens driving device, a first lens module (not shown), a first infrared filter (not shown), a first PCB 1001, a first image sensor (not shown), and a first controller (not shown). However, any one or more of the first lens driving device, the first lens module, the first infrared filter, the first PCB 1001, the first image sensor, and the first controller may be omitted or changed from the configuration of the first camera module 1000.

[0098] The first lens module may include a lens and a lens barrel (not shown). The first lens module may include one or more lenses (not shown) and a lens barrel housing one or more lenses. However, any retaining structure capable of supporting one or more lenses will be sufficient, as one element of the first lens module is limited by the lens module. The first lens module can be moved together with the first lens drive device by being coupled to it. The first lens module can be coupled internally to the first lens drive device. The first lens module can be threaded to the first lens drive device. The first lens module can be coupled to the first lens drive device by an adhesive (not shown). Meanwhile, light that has passed through the first lens module can irradiate the first image sensor.

[0099] A first infrared filter can be used to prevent light in the infrared region from entering the first image sensor. The first infrared filter can be positioned between the first lens module and the first image sensor. The first infrared filter can be disposed at a retaining member (not shown) arranged separately from the first base 1500. However, the first infrared filter can be mounted on an opening 1510 formed in the center of the first base 1500. The first infrared filter can be formed of a film material or a glass material. The first infrared filter can be formed by allowing an infrared cut-off coating material to be applied to a plate-shaped optical filter, such as an imaging plane protective cover glass or a cover glass. The first infrared filter can be an infrared cut-off filter or an infrared absorption filter.

[0100] The first PCB 1001 can support the first lens driving device. The first PCB 1001 can mount a first image sensor. For example, the first image sensor can be arranged on the inner upper side of the first PCB 1001, and a first sensor holder 1002 can be arranged on the outer upper side. Alternatively, the first lens driving device can be arranged on the upper side of the first sensor holder 1002. The first sensor holder 1002 can be integrally formed with the first base 1500. Alternatively, the first PCB 1001 can have the first lens driving device arranged on the outer upper side, and the first image sensor arranged on the inner upper side. With this structure, light that has passed through the first lens module housed inside the first lens driving device can irradiate the first image sensor mounted on the first PCB 1001. The first PCB 1001 can supply power to the first lens driving device. Simultaneously, the first PCB 1001 can be equipped with a first controller to control the first lens driving device.

[0101] A first image sensor can be mounted on a first PCB 1001. The first image sensor can be arranged to match a first lens module via an optical axis, and the first image sensor can acquire light that has passed through the first lens module via the optical axis. The first image sensor can output irradiated light in an image format. The first image sensor can be, for example, a CCD (charge-coupled device), MOS (metal-oxide-semiconductor), CPD, and CID. However, the type of the first image sensor is not limited to these.

[0102] The first controller can be mounted on the first PCB 1001. The first controller can be located outside the first lens driving device. However, the first controller can also be located inside the first lens driving device. The first controller can control the direction, intensity, and amplitude of the current supplied to each element forming the first lens driving device. The first controller can perform any or more of the autofocus function and OIS function of the first camera module 1000 by controlling the first lens driving device. That is, the first controller can move the first lens module along the optical axis or in a direction perpendicular to the optical axis, or tilt the first lens module, by controlling the first lens driving device. Furthermore, the first controller can perform feedback control of the autofocus function and the OIS function. More specifically, the first controller can control the current or power supplied to the first coil 1220 by receiving the position of the first coil holder 1220 detected by a Hall sensor (not shown), thereby providing a more precise autofocus function.

[0103] The first camera module 1000 may include a first cover member 1100, a movable member 1200, a fixed member 1300, first to fourth shielding members 1410, 1420, 1430, 1440, a third magnet unit 1411, a fourth magnet unit 1421, a first base 1500, and a first AF support member 1600. However, one or more of the first cover member 1100, movable member 1200, fixed member 1300, first to fourth shielding members 1410, 1420, 1430, 1440, third magnet unit 1411, fourth magnet unit 1421, first base 1500, and first AF support member 1600 may be omitted or changed from the first camera module 1000.

[0104] The first cover member 1100 may be integrally formed with the first housing 1310. Alternatively, the first cover member 1100 may be omitted and the first housing 1310 may be used as the first cover member 1100.

[0105] In other words, the first covering member 1100 can be the first housing 1310.

[0106] The first cover member 1100 can form the external shape of the first lens driving device. The first cover member can be a cubic shape with an open bottom. However, the invention is not limited thereto. The first cover member 1100 can be a non-magnetic material. If the first cover member 1100 is formed of a magnetic material, the magnetic force of the first cover member 1100 may be affected by the second magnet unit 2320 of the second camera module 2000. The first cover member 1100 can be formed of a metallic material. More specifically, the first cover member 1100 can be formed of a metal plate. In this case, the first cover member 1100 can shield against EMI (electromagnetic interference). Due to the aforementioned characteristics of the first cover member 1100, the first cover member 1100 can be referred to as an "EMI shielding can". The first cover member 1100 can prevent electromagnetic waves generated from the outside of the first lens driving device from entering the first cover member 1100. Furthermore, the first cover member 1100 can prevent electromagnetic waves generated from the inside of the first cover member 1100 from being emitted to the outside of the first cover member 1100. However, the material of the first cover member 1100 is not limited thereto.

[0107] The first cover member 1100 may include first to fourth side plates 1101, 1102, 1103, 1104 and a top plate 1105. The first cover member 1100 may include the top plate 1105 and first to fourth side plates 1101, 1102, 1103, 1104 extending downward from the outer side of the top plate 1105. The lower ends of the first to fourth side plates 1101, 1102, 1103, 1104 at the first cover member 1100 may be mounted on the first base 1500. The lower ends of the first to fourth side plates 1101, 1102, 1103, 1104 at the first cover member 1100 may be connected to a stepped portion 1540 of the first base 1500. The first cover member 1100 may be bonded at its inner surface to the entire or a portion of the side surface of the first base 1500. The internal space formed by the first covering member 1100 and the first base 1500 can accommodate a movable member 1200, a fixed member 1300, and a first AF support member 1600. With this structure, the first covering member 1100 can protect internal components from external vibrations and prevent the entry of foreign objects. However, the invention is not limited thereto, and the lower ends of the first side plates to the fourth side plates 1101, 1102, 1103, and 1104 at the first covering member 1100 can be directly connected to the first PCB disposed on the lower side of the first base 1500.

[0108] The first side plate 1101 may face the second covering member 2100. The first side plate 1101 may face the fifth side plate 2105 of the second covering member 2100. The first side plate 1101 may be arranged parallel to the fifth side plate 2105 of the second covering member 2100. The first side plate 1101 may be perpendicular to the third side plate 1103 and the fourth side plate 1104. The first side plate 1101 may be provided with a first shielding member 1410. The first side plate 1101 may be provided with the first shielding member 1410 by attaching it to the first shielding member 1410. In this case, the outer surface of the first side plate 1101 may contact the inner surface of the first shielding member 1410, thereby shielding the magnetic force along the magnetic field lines extending from the first magnet unit 1320 to the first side plate 1101.

[0109] The second side plate 1102 can be arranged opposite to the first side plate 1101. The second side plate 1102 can be arranged parallel to the first side plate 1101. The second side plate 1102 can be perpendicular to the third side plate 1103 and the fourth side plate 1104. The second side plate 1102 can be provided with a second shielding member 1420. The second side plate 1102 can be provided with the second shielding member 1420 by attaching it to the second shielding member 1420. In this case, the outer surface of the second side plate 1102 can contact the inner surface of the second shielding member 1420. Therefore, the magnetic force along the magnetic field lines extending from the first magnet unit 1320 to the second side plate 1102 can be shielded.

[0110] The third side plate 1103 can be positioned between the first side plate 1101 and the second side plate 1102. The third side plate 1103 can be arranged parallel to the fourth side plate 1104.

The third side plate 1103 can have the third shielding member attached to it. In this case, the outer surface of the third side plate 1103 can contact the inner surface of the third shielding member 1430. Therefore, the magnetic force along the magnetic field lines extending from the first magnet unit 1320 to the third side plate 1103 can be shielded.

[0111] A fourth side plate 1104 can be positioned between the first side plate 1101 and the second side plate 1102. The fourth side plate 1104 can be arranged parallel to the third side plate 1103.

The fourth shielding member 1440 can be disposed on the fourth side plate 1104 by attaching it to the fourth side plate 1104. In this case, the outer surface of the fourth side plate 1104 can contact the inner surface of the fourth shielding member 1440. Therefore, the magnetic force along the magnetic field lines extending from the first magnet unit 1320 to the fourth side plate 1104 can be shielded.

[0112] Two adjacent distal ends of the first to fourth side plates 1101, 1102, 1103, and 1104 can form a closed integral side surface by being adjacent to each other.

[0113] The first covering member 1100 may include an opening 1110 and an extension 1120. However, the extension 1120 may be omitted or modified from the first covering member 1100.

[0114] An opening 1110 may be formed at the upper plate 1105. The opening 1110 exposes the first lens module. The opening 1110 may be shaped to correspond to the shape of the first lens module. The opening 1110 may be larger than the diameter of the first lens module to allow the first lens module to be assembled through the opening 1110. Simultaneously, light introduced through the opening 1110 can pass through the first lens module. The light that has passed through the first lens module can then be captured by the first image sensor as an image.

[0115] The extension 1120 can be formed by bending downward from the inner surface of the upper plate 1105. The extension 1120 may be referred to as the "inner yoke". At least a portion of the extension 1120 can be formed on the first coil holder 1210 and inserted into a slot. This structure prevents the first coil holder 1210 from rotating during the threaded connection from the first lens module to the first coil holder 1210. In other cases, the extension 1120 can prevent the first coil holder 1210 from rotating relative to the first cover member 1100.

[0116] The movable member 1200 can be coupled to the first lens module. The movable member 1200 can accommodate the first lens module within its interior. The inner surface of the movable member 1200 can be coupled to the outer surface of the first lens module. The movable member 1200 can move integrally with the first lens module through electromagnetic interaction with the fixed member 1300. The movable member 1200 may include a first coil holder 1210 and a first coil 1220. However, any one or more of the first coil holder 1210 and the first coil 1220 may be omitted or modified.

[0117] The first coil holder 1210 can be disposed inside the first housing 1310. The first coil holder 1210 can be received within the through-hole 1311 of the first housing 1310. The first coil holder 1210 can be connected to the first lens module. More specifically, the inner surface of the first coil holder 1210 can be connected to the outer surface of the first lens module. The first coil holder 1210 can be connected to the first coil 1220. The lower surface of the first coil holder 1210 can be connected to the first lower support member 1620.

The first coil holder 1210 can move relative to the first housing 1310 along the optical axis.

[0118] The first coil holder 1210 may include a through hole 1211 and a coil receiving portion 1212. However, any one or more of the through hole 1211 and the receiving portion 1212 may be omitted or changed from the first coil holder 1210.

[0119] A through-hole 1211 can be formed on the inner side of the first coil holder 1210. The through-hole 1211 can be formed in an open shape on both the upper and lower sides. The through-hole 1211 can be connected to the first lens module. The through-hole 1211 can be formed on its inner surface with a thread shape corresponding to the thread shape formed on the outer side of the first lens module. That is, the through-hole 1211 can be threadedly connected to the first lens module. An adhesive can be placed between the first lens module and the first coil holder 1210. In this case, the adhesive can be an epoxy resin that is cured by heat, UV (ultraviolet light), or laser. That is, the first lens module and the first coil holder 1210 can be connected by UV-cured epoxy resin and / or heat-cured epoxy resin.

[0120] The coil receiving portion 1212 can accommodate at least a portion of the first coil 1220. The coil receiving portion 1212 can be integrally formed with the outer surface of the first coil holder 1210. Furthermore, the coil receiving portion 1212 can be formed continuously along the outer surface of the first coil holder 1210 or can be spaced apart from the outer surface of the first coil holder 1210 by a predetermined gap. For example, the coil receiving portion 1212 can be formed by allowing a portion of the outer surface of the first coil holder 1210 to be recessed into a shape corresponding to the shape of the first coil 1220. In this case, the first coil 1220 can be directly wound onto the first drive portion connecting portion 1212. As a modification, the coil receiving portion 1212 can be formed by allowing the upper or lower side to be open. In this case, the first coil 1220 can be inserted into and connected to the coil receiving portion 1212 through the open portion when in a pre-wound state.

[0121] A first coil 1220 may be arranged at a first coil holder 1210. The first coil 1220 may be arranged on the outer surface of the first coil holder 1210.

The first coil 1220 may face the first magnet unit 1320. In this case, when current is supplied to the first coil 1220 to allow the formation of a magnetic field around the first coil 1220, the first coil 1220 may move relative to the first magnet unit 1320 in response to the electromagnetic interaction between the first coil 1220 and the first magnet unit 1320. The first coil 1220 may be moved for AF driving. In this case, the first coil 1220 may be referred to as the "AF coil".

[0122] The first coil 1220 may include a pair of lead cables (not shown) for power supply. The pair of lead cables at the first coil 1220 may be electrically connected to a first lower support member 1620. Each lead cable of the first coil 1220 may be connected to a first support unit 1620a and a second support unit 1620b, respectively. In this configuration, power can be supplied to the first coil 1220 via a terminal portion 1624 electrically connected to the first lower support member 1620 of the first PCB 1001.

[0123] The fixing member 1300 may house the movable member 1200 within it. As a fixing member, the fixing member 1300 can move the movable member 1200 through electromagnetic interaction. The fixing member 1300 may include a first housing 1310 and a first magnet unit 1320. However, any one or more of the first housing 1310 and the first magnet unit 1320 may be omitted or modified.

At least a portion of the first housing 1310 may be formed in a shape corresponding to the shape of the inner surface of the first cover member 1100. Specifically, the outer surface of the first housing 1310 may be formed in a shape corresponding to the shape of the inner surface of the side plate 1102 of the first cover member 1100. For example, the first housing 1310 may be a cubic shape including four side surfaces. However, the shape of the first housing 1310 may be formed in any shape, as long as the first housing 1310 can be disposed inside the first cover member 1100. Considering productivity, the first housing 1310 may be injection formed. The first housing 1310 may be fixed to the first base 1500. As a modification, the first housing 1310 may be omitted and the first magnet unit 1320 may be fixed to the first cover member 1100. The upper surface of the first housing 1310 may be connected to the first upper support member 1610. The first housing 1310 can be connected to the first lower support member 1620 at its lower side.

The through-hole 1311 may be movably arranged to accommodate the first coil holder 1210. The through-hole 1311 may be formed in a shape corresponding to the shape of the first coil holder 1210.

[0128] A magnet receiving portion 1312 may be formed on a side surface of the first housing 1310. The magnet receiving portion 1312 may have a hole through which the first housing 1310 can pass. Alternatively, the magnet receiving portion 1312 may have a hole formed by allowing a portion of the first housing 1310 to be recessed. The magnet receiving portion 1312 may accommodate at least a portion of the first magnet unit 1320. An adhesive (not shown) may be placed between the first magnet unit 1320 and the magnet receiving portion 1312. That is, the first magnet unit 1320 and the magnet receiving portion 1312 may be joined by an adhesive. The magnet receiving portion 1312 may be disposed on an inner surface of the first housing 1310. The magnet receiving portion 1312 may be formed by allowing a portion of the inner side of the first housing 1310 to be recessed outwards.

The fourth magnet unit receiving portion may be formed in a shape corresponding to the shape of the fourth magnet unit 1421. The fourth magnet unit receiving portion may be symmetrical with the third magnet receiving portion based on the optical axis of the first camera module 1000.

[0131] A first magnet unit 1320 may be disposed at a first housing 1310. The first magnet unit 1320 may be housed within a magnet receiving portion 1312 of the first housing 1310. The first magnet unit 1320 may interact electromagnetically with a first coil 1220. The first magnet unit 1320 may face the first coil 1220. The first magnet unit 1320 may move a first coil holder 1210 fixed to the first coil 1220. The first magnet unit 1320 may move the first coil 1220 for AF actuation. In this configuration, the first magnet unit 1320 may be referred to as an "AF magnet".

[0132] The first magnet unit 1320 may include a first magnet 1321 and a second magnet 1322. The first magnet unit may include a first magnet 1321 and a second magnet 1322 spaced apart from each other.

The first magnet unit 1320 may include a first magnet 1321 arranged on the first side surface 1322 and a second magnet 1322 arranged on the third side surface 1303.

[0133] The first magnet 1321 and the second magnet 1322 may be symmetrical about the optical axis of the first camera module 1000. The first magnet 1321 and the second magnet 1322 may have dimensions and shapes symmetrical about the optical axis of the first camera module 1000.

The first magnet 1321 and the second magnet 1322 may be arranged parallel to each other. Each of the first magnet 1321 and the second magnet 1322 may be arranged to face inwards with the same polarity. The N pole of the first magnet 1321 and the second magnet 1322 may be arranged to face inwards. The first magnet 1321 and the second magnet 1322 may be formed into a flat, plate-like shape. The first magnet 1321 and the second magnet 1322 may be referred to as "plate-shaped magnets".

[0134] The third magnet unit 1411 can be arranged on the side surface of the first housing 1310 facing the second housing 2310. The third magnet unit 1411 can also be arranged on the second side surface 1302 of the first housing 1310.

The third magnet unit 1411 can be smaller than the second magnet 1322. The third magnet unit 1411 can be arranged on a virtual line connecting the optical axis of the first camera module 1000 and the optical axis of the second camera module 2000.

[0135] The third magnet unit 1411 can be arranged to face inward with the same polarity as the first magnet 1321 and the second magnet 1322. The S pole of the third magnet unit 1411 can be arranged to face inward. Alternatively, the third magnet unit 1411 can be arranged with its S pole facing inward.

[0136] When viewed from the top surface, the length of the third magnet 1411 along the direction parallel to the second side surface 1302 (see...) Figure 13 (1-3) can be shorter than the separation distance between the third magnet 2321 and the sixth magnet 2324 (see Figure 13 (1-4). Under these conditions, the third magnet unit 1411 can minimize the influence of the first magnet unit 1320 on the second magnet unit 2320. When viewed from the top surface, the length 1-3 of the third magnet unit 1411 in the direction parallel to the second side surface 1302 can be 1 mm. The length 1-3 of the third magnet unit 1411 in the direction parallel to the second side surface 1302 can be 0.8 mm to 1.2 mm. The length 1-3 of the third magnet unit 1411 in the direction parallel to the second side surface 1302 can be 0.5 mm to 1.5 mm.

[0137] When viewed from the top surface, the length 1-3 of the third magnet unit 1411 in the direction parallel to the second side surface 1302 can be less than the longitudinal length of the first magnet 1321 in the direction parallel to the first side surface 1301 (see...). Figure 13The third magnet unit 1411 can minimize the influence of the first magnet unit 1320 on the second magnet unit 2320. At the same time, the length 1-3 of the third magnet unit 1411 in the direction parallel to the second side surface 1302 can be greater than 0.5 mm.

[0138] In this exemplary embodiment, the arrangement of the third magnet unit 1411 on the AF camera module having a flat magnet minimizes the magnetic force exerted by the magnet of the AF camera module on the corner magnet of the OIS camera module. If the third magnet unit 1411 is removed in this exemplary embodiment without current correction, the optical axis of the second camera module 2000 can be moved by more than 5 μm.

[0139] A fourth magnet unit 1421 may be disposed at the first housing 1310. The fourth magnet unit 1421 may be disposed at the fourth side surface 1304 of the first housing 1310. The fourth magnet unit 1421 may be arranged symmetrically with the third magnet unit 1411 about the center of the optical axis of the first camera module 1000. The fourth magnet unit 1421 may be disposed at a position corresponding to the position of the third magnet unit 1411 about the center of the optical axis of the first camera module 1000. The fourth magnet unit 1421 may have a size and shape corresponding to the size and shape of the third magnet unit 1411 about the center of the optical axis of the first camera module 1000. The fourth magnet unit 1421 may be placed between the first magnet 1321 and the second magnet 1322. The fourth magnet unit 1421 may be smaller than the first magnet 1321. The fourth magnet unit 1421 may have a width smaller than the first magnet 1321. The fourth magnet unit 1421 may have a thickness thinner than the first magnet 1321.

The fourth magnet unit 1421 may be smaller than the second magnet 1322.

[0140] The fourth magnet unit 1421 can be arranged on a virtual line connecting the optical axis of the first camera module 1000 and the optical axis of the second camera module 2000. The fourth magnet unit 1421 can be arranged to face inwards with the same polarity as the first magnet 1321 and the second magnet 1322. The fourth magnet unit 1421 can also be arranged to face inwards with the same polarity as the third magnet unit 1411. The N pole of the fourth magnet unit 1421 can be arranged to face inwards. Alternatively, the fourth magnet unit 1421 can face inwards with its S pole facing inwards.

[0141] In this exemplary embodiment, the arrangement of the fourth magnet unit 1421 corresponding to the third magnet unit 1411 can counteract the effect of the AF drive of the first camera module 1000 on the third magnet unit 1411. Alternatively, the fourth magnet unit 1421 can have a symmetrical effect relative to the effect of the third magnet unit 1411 on the AF drive of the first camera module 1000.

[0142] The first to fourth shielding members 1410, 1420, 1430, and 1440 can be formed of a material that shields magnetic forces. The first to fourth shielding members 1410, 1420, 1430, and 1440 can be metallic or magnetic materials. The first to fourth shielding members 1410, 1420, 1430, and 1440 can be respectively arranged at the first to fourth side plates 1101, 1102, 1103, and 1104 of the first covering member 1100. The first to fourth shielding members 1410, 1420, 1430, and 1440 can have a flat, plate-like shape. In this case, the inner surface of the flat, plate-like member can be arranged to contact the outer surfaces of the first to fourth side plates 1101, 1102, 1103, and 1104 of the first covering member 1100. The first to fourth shielding members 1410, 1420, 1430, and 1440 can be integrally formed by connecting them to each other. The distal ends of adjacent shielding members are connected to form an integral shielding member. In this case, the first to fourth shielding members 1410, 1420, 1430, and 1440 can cover all the outer surfaces of the first to fourth side plates 1101, 1102, 1103, and 1104.

[0143] The first shielding member 1410 can be disposed at the first side plate 1101. The first shielding member 1410 can be disposed facing the fifth side plate 2101 of the second covering member 2100. The second shielding member 1420 can be disposed parallel to the fifth side plate 2101. The first shielding member 1410 can be disposed parallel to the second shielding member 1420. The first shielding member 1410 can be disposed perpendicular to the third shielding member 1430 and the fourth shielding member 1440. The first shielding member 1410 can have a flat plate shape. In this case, the inner surface of the first shielding member 1410 can be disposed in contact with the outer surface of the first side plate 1101. Furthermore, the longitudinal length of the first shielding member 1410 can be longer than the longitudinal length of the first side plate 1101. Furthermore, the lateral length of the first shielding member 1410 can be longer than the lateral length of the first side plate 1101. Therefore, the first shielding member 1410 can shield the magnetic force emitted to the outside through the first side plate 1101 by covering the entire first side plate 1101.

[0144] The magnetic force along the magnetic field lines extending from the first magnet unit 1320 to the first side plate 1101 can be formed close to the second magnet unit 2320 arranged in the second housing 2310. Therefore, the magnetic field of the second magnet unit 2320 may be interfered with by the magnetic field of the first magnet unit 1320. However, the magnetic force acting on the second magnet unit 2320 by the first magnet unit 1320 can be shielded by the first shielding member 1410. That is, the magnetic force of the first magnet unit 1320 can prevent interference from the magnetic field of the second magnet unit 2320. Therefore, the second housing 2310 can be prevented from tilting towards the first lens driving device or towards the opposite side. Furthermore, the second housing 2310 can be unaffected by the magnetic force of the first magnet unit 1320 and can be driven according to preset design conditions.

[0145] The second shielding member 1420 can be disposed at the second side plate 1102. The second shielding member 1420 can be disposed opposite to the first shielding member 1410. The second shielding member 1420 can be disposed parallel to the first shielding member 1410. The second shielding member 1420 can be disposed perpendicular to the third shielding member 1430 and the fourth shielding member 1440. The second shielding member 1420 can have a flat, plate-like shape. In this case, the inner surface of the second shielding member 1420 can be disposed in contact with the outer surface of the second side plate 1102. Furthermore, the longitudinal length of the second shielding member 1420 can be longer than the longitudinal length of the second side plate 1102. Furthermore, the transverse length of the second shielding member 1420 can be longer than the transverse length of the second side plate 1102. Therefore, the second shielding member 1420 can cover the entire second side plate 1102 to shield magnetic forces emitted to the outside through the second side plate 1102.

[0146] The magnetic force along the magnetic lines of force extending from the first magnet unit 1320 to the second side plate 1102 can be arranged close to the receiver 3000 in the components of the aforementioned optical device.

However, the magnetic force exerted on the receiver 3000 by the first magnet unit 1320 can be shielded by the second shielding member 1420. That is, the generation of EMI (electromagnetic interference) on the receiver can be prevented by the magnetic force of the first magnet unit 1320. Therefore, the receiver 3000 can receive electronic signals according to preset design conditions without any electronic interference noise, or it can output the received electronic signals as audio signals by converting them into audio signals. Furthermore, the first camera module 1000 can be driven in response to preset driving conditions without interference from the electronic signals received from the receiver 3000.

However, the second controller can also be located internally to the second lens drive unit. The second controller can control the direction, intensity, and amplitude of the current supplied to each element forming the second lens drive unit. The second controller can perform any or more of the autofocus and OIS functions of the second camera module 2000 by controlling the second lens drive unit. That is, the second controller can move the second lens module along the optical axis or in a direction perpendicular to the optical axis, or tilt the second lens module, by controlling the second lens drive unit. Furthermore, the second controller can perform feedback control of the autofocus and OIS functions. More specifically, the second controller can control the current or power supplied to the second coil 2220 and / or the third coil 2422 by receiving the position of the second coil holder 2220 and / or the second housing 2310 detected by the Hall sensor 2800 and other sensors (not shown), thereby providing more precise autofocus and / or OIS functions.

The light that has passed through the second lens module can then be captured by the second image sensor as an image.

[0185] A marking portion 2120 may be formed on the upper plate 2102 of the second cover member 2100. The marking portion 2120 may be formed to allow a worker to see the orientation of the second cover member 2100 at a glance. In the case of an OIS lens drive device, orientation is important during soldering to the PCB, so the marking portion 2120 may be formed to allow a worker to easily identify the orientation of the OIS lens drive device.

[0234] As discussed above, the dual-camera module according to the exemplary embodiment can minimize magnetic field interference through the arrangement and shape of the first to fourth magnet units 1320, 2320, 1410, 1420 and the arrangement and shape of the first to fourth shielding members 1410, 1420, 1430, 1440.

[0235] However, by designing intelligent requirements, at least one of the third magnet unit 1410 and the fourth magnet unit 1420, as well as the first to fourth shielding members 1410, 1420, 1430, 1440, can be omitted from the dual-camera module according to the exemplary embodiment, and thus, various exemplary embodiments can be implemented.

[0236] Hereinafter, the dual-camera modules according to the first to seventh exemplary embodiments will be described with reference to the accompanying drawings. However, the dual-camera modules according to the first to seventh exemplary embodiments are part of various exemplary embodiments of the dual-camera modules according to this exemplary embodiment, and therefore, the scope of the dual-camera modules according to this exemplary embodiment is not limited to the dual-camera modules according to the first to seventh exemplary embodiments.

[0237] Hereinafter, the first exemplary embodiment, the second exemplary embodiment, and the third exemplary embodiment will be described with reference to the accompanying drawings. Figure 12 This is a perspective view of a dual-camera module according to a first exemplary embodiment of the present invention, as viewed from a flat surface. Figure 13 This is a conceptual diagram of a dual-camera module according to a first exemplary embodiment of the present invention. Figure 14 This is a conceptual diagram of a dual-camera module according to a second exemplary embodiment of the present invention, and Figure 15 This is a conceptual diagram of a dual-camera module according to a third exemplary embodiment of the present invention.

[0238] The dual-camera modules according to the first, second, and third exemplary embodiments are of the type where the first to fourth shielding members 1410, 1420, 1430, and 1440 are removed. When magnetic field interference is sufficiently limited by the arrangement and shape of the first to fourth magnet units 1320, 2320, 1410, and 1420, the first to fourth shielding members 1410, 1420, 1430, and 1440 can all be omitted.

[0239] The dual-camera module according to the first exemplary embodiment is the case where all the first to fourth magnet units 1320, 2320, 1410, and 1420 are present (see...). Figure 12 and Figure 13 The dual-camera module according to the second exemplary embodiment is the case where the fourth magnet unit 1421 is not present.

[0240] In this case, the size of the third magnet unit 1411 can be changed. The size of the third magnet unit 1411 according to the second exemplary embodiment can be larger than the size of the third magnet unit 1411 according to the first exemplary embodiment. Alternatively, the size of the third magnet unit 1411 according to the second exemplary embodiment can be smaller than the size of the third magnet unit 1411 according to the first exemplary embodiment. Even if the fourth magnet unit 1421 is omitted and the third magnet unit 1411 is arranged as in the second exemplary embodiment, the flat magnet of the AF camera module can reduce the impact on the corner magnet of the OIS camera module to some extent.

[0241] According to the third exemplary embodiment, the dual-camera module omits the third magnet unit 1421 and the fourth magnet unit 1422 (see [reference]). Figure 15 In this case, since the third magnet unit 1411 is omitted, the effect of the flat magnet of the AF camera module acting on the corner magnet of the OIS camera module may still exist. Therefore, in the third exemplary embodiment, the separation distance between the AF camera module and the OIS camera module can be more spaced than in the above exemplary embodiment. At the same time, even in the third exemplary embodiment, compared with the case where a flat magnet of the same size as the first magnet 1321 is arranged on the second side surface 1302 of the first housing 1310, it can be seen that the effect of the flat magnet of the AF camera module acting on the corner magnet of the OIS camera module has been reduced.

[0242] The fourth, fifth, sixth, and seventh exemplary embodiments will be described below with reference to the accompanying drawings. Figure 16 This is a plan view of a dual-camera module according to a fourth exemplary embodiment of the present invention. Figure 17 This is a plan view of a dual-camera module according to a fifth exemplary embodiment of the present invention. Figure 18 This is a plan view of a dual-camera module according to a sixth exemplary embodiment of the present invention, and Figure 19 This is a plan view of a dual-camera module according to a seventh exemplary embodiment of the present invention.

[0243] The dual-camera modules according to the fourth, fifth, sixth, and seventh exemplary embodiments are characterized by the presence of at least one of the first to fourth shielding members 1410, 1420, 1430, and 1440. Furthermore, the dual-camera modules according to the fourth, fifth, sixth, and seventh exemplary embodiments are characterized by the omission of the third magnet unit 1410 and the fourth magnet unit 1420.

[0244] When magnetic field interference between the dual camera modules is not sufficiently limited by the arrangement and shape of the first to fourth magnet units 1320, 2320, 1410, 1420, or when magnetic field interference occurs with a peripheral device such as receiver 3000, magnetic field interference can be limited by using at least one of the first to fourth shielding members 1410, 1420, 1430, 1440.

[0245] In this case, the following situation may exist: the magnetic force of the first magnet unit 1320 acts only on the second magnet unit 2320 of the second camera module 2000, and the magnetic force of the first magnet unit 1320 acts only on the second magnet unit 2320 and the receiver 3000, so that all or part of the second to fourth shielding members 1420, 1430, and 1440 can be omitted to reduce material costs and for optical design.

[0246] The dual-camera module according to the fourth exemplary embodiment is the case where all the first to fourth shielding members 1410, 1420, 1430, and 1440 are present. Figure 16 According to the fifth exemplary embodiment, the dual-camera module is provided in the presence of a first shielding member 1410 and a second shielding member 1420. Figure 17 The dual-camera module according to the sixth exemplary embodiment is the case where only the second shielding member 1420 exists. Figure 18 The dual-camera module according to the seventh exemplary embodiment is the case where only the first shielding member 1410 exists. Figure 19 ).
