Description

Electronic device including a camera module

[0001] Various embodiments disclosed in this document relate to an electronic device including a camera module.

[0002] Various electronic devices, such as smart phones, tablet PCs, portable multimedia players (PMPs), personal digital assistants (PDAs), laptop personal computers, and wearable devices such as wrist watches and head-mounted displays (HMDs), contain cameras and can capture images using cameras.

[0003] As the number of users using electronic devices to take photos and videos increases, the performance of cameras embedded in these devices is also improving. For example, when taking images using a camera embedded in an electronic device, adjusting the focus of the subject or compensating for any camera shake (e.g., hand shake) that may occur during the capture may be necessary to obtain a clear image.

[0004] A camera module used in an electronic device may include an auto focus (AF) function that automatically adjusts the focus of a lens on a subject and / or an optical image stabilizer (OIS) function that compensates for shaking that occurs in the camera module when photographing a subject. The AF function and the optical image stabilizer function of the camera module may be driven based on an electromagnetic force using a magnet and a coil.

[0005] The above information may be provided as background art to aid in understanding the present disclosure. No claim or determination is made as to whether any of the above-described matters constitute prior art related to the present disclosure.

[0006] According to one embodiment of the present disclosure, the aperture module is coupled to the lens assembly and moves together with the lens assembly during auto focus (AF) or image stabilization (optical image stabilizer (OIS)), so that the center of the incident area formed by the aperture module (e.g., the area where light passes through the aperture module) and the center of the lens are aligned.

[0007] The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those with ordinary skill in the technical field to which this document pertains from the description below.

[0008] In an electronic device including a camera module according to one embodiment disclosed in the present document, the camera module may include a camera housing and a first carrier disposed in the camera housing. The camera module may include a lens assembly, at least a portion of which is accommodated in the first carrier and includes at least one lens. The camera module may include an aperture module disposed on an upper portion of the lens assembly and configured to adjust the amount of light entering the lens depending on an open state. The camera module may include a slider, at least a portion of which is coupled to the aperture module and which moves in a first axial direction with respect to the first carrier. The camera module may include a bearing ball disposed between the slider and the first carrier. The camera module may include a drive magnet disposed in the slider. The camera module may include a first OIS magnet disposed in the slider. The camera module may include a drive coil facing one surface of the drive magnet at a lower portion of the slider and having an electromagnetic force acting on the drive magnet so that the slider moves in the first axial direction. The camera module may include a first OIS coil facing one side of the first OIS magnet at the bottom of the slider and subjected to an electromagnetic force with the first OIS magnet so that the first carrier and the slider move in a second axial direction perpendicular to the first axial direction.

[0009] According to one embodiment disclosed in the present document, a camera module may include a camera housing. The camera module may include a first carrier disposed in the camera housing. The camera module may include a lens assembly, at least a portion of which is accommodated in the first carrier and includes at least one lens. The camera module may include an aperture module disposed on an upper portion of the lens assembly and configured to adjust the amount of light entering the lens depending on an open state. The camera module may include a slider, at least a portion of which is coupled to the aperture module and which moves in a first axial direction with respect to the first carrier. The camera module may include a bearing ball disposed between the slider and the first carrier. The camera module may include a drive magnet disposed on the slider. The camera module may include a first OIS magnet disposed on the slider. The camera module may include a drive coil facing one surface of the drive magnet at a lower portion of the slider and having an electromagnetic force acting on the drive magnet so that the slider moves in the first axial direction. The camera module may include a first OIS coil facing one side of the first OIS magnet at the bottom of the slider and subjected to an electromagnetic force with the first OIS magnet so that the first carrier and the slider move in a second axial direction perpendicular to the first axial direction.

[0010] According to various embodiments disclosed herein, the aperture module can be coupled to the lens assembly. Accordingly, the aperture module can move together with the lens assembly during autofocus adjustment or image stabilization to compensate for image shake, thereby maintaining the center of the incident area formed by the aperture module and the center of the lens aligned.

[0011] Additionally, the camera module may include an aperture module that controls the amount of light from the lens. The aperture module is coupled to a linearly movable slider, and the opening state can be adjusted based on the movement of the slider. Meanwhile, the OIS magnet used for image shake control and the drive magnet used for controlling the aperture module can be arranged together on the slider. Accordingly, since the area where the drive magnet and the OIS magnet are arranged is shared, no additional space is required for arranging the OIS magnet or the drive magnet, thereby reducing the size of the camera module.

For example, when image acquisition is delayed due to a shutter, or when multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in the memory (250), and a corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Thereafter, when a specified condition is satisfied (e.g., a user input or a system command), at least a portion of the original image stored in the memory (250) can be acquired and processed, for example, by the image signal processor (260). According to one embodiment, the memory (250) may be configured as at least a portion of the memory (130), or as a separate memory that operates independently therefrom.

[0061] The image signal processor (260) can perform one or more image processing operations on an image acquired through an image sensor (230) or an image stored in a memory (250). The one or more image processing operations may include, for example, depth map generation, 3D modeling, panorama generation, feature extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor (260) may perform control (e.g., exposure time control, read-out timing control, etc.) for at least one of the components included in the camera module (180) (e.g., image sensor (230)). An image processed by the image signal processor (260) may be stored back in the memory (250) for further processing or provided to an external component of the camera module (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108)). According to one embodiment, the image signal processor (260) may include at least one of the processors (120). It may be configured as a separate processor that is configured as a part of the processor (120) or operates independently of the processor (120). If the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (160) as is or after undergoing additional image processing by the processor (120).

[0062] According to one embodiment, the electronic device (101) may include a plurality of camera modules (180), each having different properties (e.g., angle of view) or functions. In this case, for example, the plurality of camera modules (180) may include at least one of a wide-angle camera, a telephoto camera, or an IR Camera (time of flight camera, structured light camera). For example, a plurality of camera modules including lenses having different angles of view are configured, and the electronic device may be controlled to change the angle of view variably according to a user's selection. According to one embodiment, at least one of the plurality of camera modules (180) may be a front camera, and at least another may be a rear camera.

[0063] FIGS. 3A and 3B are perspective views of a camera module according to one embodiment of the present disclosure. FIG. 4 is an exploded perspective view of a camera module according to one embodiment of the present disclosure.

[0064] According to one embodiment of the present disclosure, a camera module (300) (e.g., the camera module (180) of FIG. 1) may include an aperture module (400), a lens assembly (310), a shield can (320), a first carrier (340) (e.g., an OIS carrier), a slider (410), a second carrier (350) (e.g., an AF carrier), a stopper (330), a flexible printed circuit board (370) electrically connected to a plurality of magnets (e.g., a driving magnet (511), a first OIS magnet (521), and / or a second OIS magnet (531)), a plurality of coils (e.g., a driving coil (512), a first OIS coil (522), and / or a second OIS coil (532)), and a camera housing (360). The configuration of the camera module (300) described above is an example, and at least one of the configurations described above may be omitted or at least one configuration may be added to the camera module (300).

[0065] According to one embodiment, as illustrated in FIGS. 3A, 3B, and 4, the camera module (300) may include a first carrier (340) and a second carrier (350) disposed inside a camera housing (360). In one embodiment, the first carrier (340) may be a housing that accommodates a lens assembly (310). The second carrier (350) may be a housing that accommodates the first carrier (340). In one embodiment, the first carrier (340) may be disposed inside the second carrier (350) while accommodating the lens assembly (310). In one embodiment, the second carrier (350) may be disposed inside the camera housing (360). In one embodiment, referring to FIGS. 3A and 3B, the first carrier (340) may have an open upper surface so that the lens assembly (310) may be disposed therein. The second carrier (350) may have an open top surface so that the first carrier (340) can be placed thereon and may provide a space in which the first carrier (340) can be seated. In one embodiment, the camera housing (360) may have an open top surface so that the second carrier (350) can be placed thereon and may provide a space in which the second carrier (350) can be seated thereon.

[0066] In one embodiment, referring to FIG. 4, the lens assembly (310) may include at least one lens (312) and a lens barrel (311) (e.g., a barrel) in which the lens (312) is disposed. In one embodiment, the lens barrel (311) may be a housing that accommodates a plurality of lenses (312). In one embodiment, the plurality of lenses (312) may be arranged within the lens barrel (311) along an optical axis of the lens (e.g., the Z-axis of FIGS. 3A and 3B).

[0067] In one embodiment, the lens assembly (310) can be moved for auto focus (AF) control to automatically adjust the focus of the lens (312) on a subject and for optical image stabilizer (OIS) to compensate for shake that occurs in the camera module (300) when capturing a subject. For example, the lens assembly (310) can be placed on the second carrier (350) while being placed on the first carrier (340). Accordingly, the lens assembly (310) can be moved together with the first carrier (340) and the second carrier (350). In one embodiment, the lens assembly (310) can be moved along the optical axis as the second carrier (350) moves relative to the camera housing (360) along the optical axis (e.g., the Z-axis direction of FIG. 3A) for focus control of the lens (312). In one embodiment, when the first carrier (340) moves in a first axis direction (e.g., the X-axis direction of FIG. 3A) and / or a second axis direction (e.g., the Y-axis direction of FIG. 3A) perpendicular to the optical axis relative to the camera housing (360) and / or the second carrier (350) for image shake compensation, the lens assembly (310) may move in the first axis direction and / or the second axis direction together with the first carrier (340).

[0068] In one embodiment, referring to FIGS. 3A, 3B, and 4, an aperture module (400) may be arranged on the upper portion of the lens assembly (310). The aperture module (400) may control the amount of light entering the lens (312) of the lens assembly (310). For example, the aperture module (400) may form an incident area (A) corresponding to at least a portion of the lens (312). In one embodiment, the incident area (A) may be a space formed by a plurality of plates (403) of the aperture module (400), which will be described later. The aperture module (400) may control the amount of light entering the lens (312) by controlling the size of the incident area (A). For example, the processor (120) may control the aperture module (400) so that the incident area (A) is expanded in a relatively dark environment. The processor (120) can control the aperture module (400) to reduce the incident area (A) in a relatively bright environment. As will be described later, the size of the incident area (A) of the aperture module (400) can be varied as the slider (410) moves in the first axial direction (e.g., the X-axis direction of FIG. 3A) with respect to the first carrier (340). In one embodiment, the aperture module (400) can vary the size of the incident area (A) depending on the degree of opening. For example, when the aperture module (400) is in the maximum opening state, the size of the incident area (A) can also be maximum.

[0069] In one embodiment, referring to FIGS. 3A, 3B, and 4, the camera module (300) may include a slider (410) movable relative to a first carrier (340). In one embodiment, the slider (410) may be coupled with the first carrier (340) to move in a first axial direction (e.g., the X-axis direction in FIG. 3A) relative to the first carrier (340). In one embodiment, the slider (410) may be coupled with the first carrier (340) with a bearing ball (b1) therebetween to move in the first axial direction (e.g., the X-axis direction in FIG. 4) relative to the first carrier (340). The bearing ball (b1) may guide movement of the slider (410) relative to the first carrier (340) in the first axial direction (e.g., the X-axis direction in FIG. 4). In one embodiment, the slider (410) may be positioned at the bottom of the first carrier (340), as illustrated in FIGS. 3A, 3B, and 4, but is not limited thereto.

[0070] In one embodiment, the slider (410) can be coupled with the aperture module (400) to adjust the opening state of the aperture module (400). For example, the aperture module (400) can adjust the size of the incident area (A) where light enters the lens (312) based on the first axial movement of the slider (410) with respect to the first carrier (340). A specific coupling relationship between the aperture module (400) and the slider (410) will be described below with reference to FIG. 4.

[0071] In one embodiment, referring to FIGS. 3A, 3B, and 4, the aperture module (400) can be moved together with the lens assembly (310) as it is coupled to the lens assembly (310). For example, when the camera module (300) moves along the optical axis (e.g., the Z-axis direction of FIG. 3A) with respect to the camera housing (360) for focus adjustment of the lens (312), the lens assembly (310) can be moved along the optical axis. In addition, when the camera module (300) moves in the first axis direction (e.g., the X-axis direction of FIG. 3A) and / or the second axis direction (e.g., the Y-axis direction of FIG. 3A) perpendicular to the optical axis with respect to the camera housing (360) and / or the second carrier (350) for image shake correction, the aperture module (400) can move in the first axis direction and / or the second axis direction together with the lens assembly (310). Accordingly, the aperture module (400) can move together with the lens assembly (310) during automatic focus adjustment and / or image stabilizer for image shake correction, thereby maintaining the alignment of the center of the incident area (A) formed by the aperture module (400) and the center of the lens (312).

[0072] In one embodiment, referring to FIG. 4, the shield can (320) may be positioned at the outermost portion of the camera module (300) and at least partially surround the camera housing (360). In one embodiment, the shield can (320) may block or reduce electromagnetic waves generated from the outside of the camera module (300), thereby reducing malfunctions of the camera module (300). In one embodiment, the shield can (320) may be formed of a material that shields electromagnetic waves, such as copper, iron, aluminum, and / or nickel, and may be formed of various materials that can be implemented by a person skilled in the art in addition to the materials described above.

[0073] In one embodiment, referring to FIG. 4, at least a portion of the stopper (330) may be coupled to the second carrier (350). In one embodiment, the stopper (330) may be disposed between the shield can (320) and the first carrier (340) and a portion thereof may be coupled to the second carrier (350). In one embodiment, the stopper (330) may prevent the first carrier (340) from being separated from the second carrier (350). For example, the stopper (330) may prevent the first carrier (340) from being separated or lifted in the Z-axis direction of FIG. 4 relative to the second carrier (350).

[0074] In one embodiment, referring to FIG. 4, the camera module (300) may include a flexible printed circuit board (370) disposed on a second carrier (350). In one embodiment, the flexible printed circuit board (370) may be electrically connected to the drive coil (512), the AF coil (542), the first OIS coil (522), and the second OIS coil (532). The processor (120) may be disposed on a substrate (not shown) of the electronic device (101) and may supply current to the drive coil (512), the AF coil (542), the first OIS coil (522), and the second OIS coil (532) through the flexible printed circuit board (370) to provide driving force to the slider (410), the first carrier (340), and the second carrier (350). In one embodiment, the AF coil (542) may be connected to a separate substrate (e.g., a flexible printed circuit board) other than the flexible printed circuit board (370) and may be controlled by the processor (120). In one embodiment, when the AF coil (542) is disposed in the camera housing (360), the AF coil (542) may be electrically connected to the printed circuit board on which the processor (120) is disposed through a flexible printed circuit board (not shown) other than the flexible printed circuit board (370) connected to the drive coil (512), the first OIS coil (522), and the second OIS coil (532), and may be controlled by the processor (120). In one embodiment, when the AF coil (542) is placed on the second carrier (350), the AF coil (542) may be electrically connected to the processor (120) via another flexible printed circuit board (not shown) that is electrically connected to the flexible printed circuit board (370) connected to the drive coil (512), the first OIS coil (522), and the second OIS coil (532).

[0075] In one embodiment, referring to FIGS. 3B and 4, the slider (410) can be moved in a first axial direction relative to the first carrier (340) via a drive actuator. In one embodiment, the drive actuator can include a drive magnet (511) disposed on the slider (410) and a drive coil (512) connected to a flexible printed circuit board (370). In one embodiment, the drive magnet (511) can be disposed on a back surface of the slider (410) (e.g., a surface facing the -Z direction in FIG. 4) such that at least a portion of the drive coil (512) disposed on the flexible printed circuit board (370) faces the slider (410). The slider (410) can be moved in the first axial direction relative to the first carrier (340) via an electromagnetic force acting between the drive magnet (511) and the drive coil (512).

[0076] In one embodiment, the camera module (300) can adjust the amount of light entering the lens (312) by moving the slider (410) in a first axial direction relative to the first carrier (340) under the control of the processor (120). For example, the processor (120) can analyze ambient lighting conditions to control the open state of the aperture module (400) by applying current to the drive coil (512) and moving the slider (410) in the first axial direction.

[0077] In one embodiment, the camera module (300) can adjust the depth of field of a subject by moving the slider (410) in the first axial direction relative to the first carrier (340) under the control of the processor (120). In one embodiment, as the aperture module (400) opens, the size of the incident area (A) increases, so that the amount of light entering the lens (312) increases and the depth of field of the subject may become shallower. In this case, the subject may become clearer and the background surrounding the subject may become blurred. In one embodiment, as the incident area (A) of the aperture module (400) decreases, the amount of light entering the lens (312) decreases, so that the depth of field of the subject may become deeper. In this case, not only the subject but also the background surrounding the subject may become clearer.

[0078] In one embodiment, referring to FIGS. 3A, 3B, and 4, the second carrier (350) may be an AF (auto focus) drive unit. According to one embodiment, the camera module (300) may adjust the focus by moving the second carrier (350) under the control of the processor (120). In one embodiment, the second carrier (350) may move in the optical axis direction of the lens (312) (e.g., the Z-axis direction of FIG. 4) via the AF actuator. In one embodiment, the AF actuator may include an AF coil (542) disposed in one of the camera housing (360) and the second carrier (350) and an AF magnet (541) disposed in the other of the camera housing (360) and the second carrier (350). In one embodiment, the AF coil (542) may be connected to a separate substrate (e.g., a flexible printed circuit board) other than the flexible printed circuit board (370) and may be controlled via the processor (120). In one embodiment, when the AF coil (542) is disposed in the camera housing (360), the AF coil (542) may be electrically connected to the printed circuit board on which the processor (120) is disposed through a flexible printed circuit board (370) connected to the drive coil (512), the first OIS coil (522), and the second OIS coil (532) and another flexible printed circuit board (not shown) that is electrically connected to the printed circuit board and may be controlled by the processor (120). In one embodiment, when the AF coil (542) is disposed in the second carrier (350), the AF coil (542) may be electrically connected to the processor (120) through another flexible printed circuit board (not shown) that is electrically connected to the flexible printed circuit board (370) connected to the drive coil (512), the first OIS coil (522), and the second OIS coil (532).

[0079] In one embodiment, referring to FIG. 4, the AF coil (542) may be disposed on one surface of the camera housing (360), and the AF magnet (541) may be disposed on one surface of the second carrier (350) to face the AF coil (542). In one embodiment, the second carrier (350) may move in the direction of the optical axis through an electromagnetic force (e.g., Lorentz force or solenoid force) acting between the AF coil (542) and the AF magnet (541) to automatically adjust the focus of the lens (312) on the subject, thereby performing an AF (auto focus) function.

[0080] In one embodiment, the AF coil (542) may be disposed on a side of the camera housing (360) (e.g., a side facing the + Y direction in FIG. 4), and the AF magnet (541) may be disposed on a side of the second carrier (350) to face the AF coil (542). In this case, the second carrier (350) may move in the optical axis direction through an electromagnetic force (e.g., Lorentz force) acting between the AF coil (542) and the AF magnet (541), thereby adjusting the focus of the lens (312) on the subject. In one embodiment, referring to FIG. 4, the AF magnet (541) may be disposed such that its N pole and S pole face the AF coil (542). In this case, the AF magnet (541) can be moved parallel to the optical axis direction (e.g., the Z-axis direction of FIG. 4) with respect to the AF coil (542) while maintaining a vertical distance from the AF coil (542) through an electromagnetic force (e.g., Lorentz force) acting on the AF coil (542) while being coupled to the second carrier (350).

[0081] In one embodiment, the AF coil (542) may be disposed on one surface (e.g., the bottom surface, the surface facing the +Z direction in FIG. 4) of the camera housing (360), and the AF magnet (541) may be disposed on one surface (e.g., the bottom surface, the surface facing the -Z direction in FIG. 4) of the second carrier (350) so as to face the AF coil (542). In one embodiment, when one of the N pole and the S pole of the AF magnet (541) is disposed so as to face the AF coil (542), an electromagnetic force (e.g., a solenoid force) may act between the AF coil (542) and the AF magnet (541). The vertical distance of the AF magnet (541) with respect to the AF coil (542) may be changed through the electromagnetic force (e.g., the solenoid force) acting on the AF coil (542). Accordingly, the second carrier (350) can move in the direction of the optical axis through an electromagnetic force (e.g., solenoid force) acting between the AF coil (542) and the AF magnet (541) to adjust the focus of the lens (312) on the subject.

[0082] In one embodiment, the AF coil (542) may be electrically connected to the processor (120). The processor (120) controls a driving circuit (e.g., a driver IC) (not shown) of the camera module (300), so that current generated in the driving circuit may be supplied to the AF coil (542) through a substrate (e.g., a flexible printed circuit board (370) or a separate flexible printed circuit board) connected to the driving circuit. In one embodiment, the AF coil (542) may be connected to a separate substrate (e.g., a flexible printed circuit board) different from the flexible printed circuit board (370) and controlled through the processor (120). In one embodiment, when the AF coil (542) is disposed in the camera housing (360), the AF coil (542) may be electrically connected to the printed circuit board on which the processor (120) is disposed through a flexible printed circuit board (370) connected to the drive coil (512), the first OIS coil (522), and the second OIS coil (532) and another flexible printed circuit board (not shown) that is electrically connected to the printed circuit board and may be controlled by the processor (120). In one embodiment, when the AF coil (542) is disposed in the second carrier (350), the AF coil (542) may be electrically connected to the processor (120) through another flexible printed circuit board (not shown) that is electrically connected to the flexible printed circuit board (370) connected to the drive coil (512), the first OIS coil (522), and the second OIS coil (532). Accordingly, an electromagnetic effect is induced between the AF coil (542) and the AF magnet (541), and the second carrier (350) can move in the optical axis direction with respect to the camera housing (360).

[0083] In one embodiment, the camera module (300) can compensate for image shake (e.g., optical image stabilizer (OIS)) by moving the first carrier (340) relative to the second carrier (350) under the control of the processor (120). In one embodiment, the electronic device (101) can compensate for image shake by moving the first carrier (340) in the opposite direction to the direction in which the camera module (300) shakes. In one embodiment, the first carrier (340) can be moved in a first axis (e.g., the X-axis of FIG. 4) and / or a second axis (e.g., the Y-axis of FIG. 4) direction substantially perpendicular to the optical axis relative to the second carrier (350) and / or the camera housing (360) via the first OIS actuator and the second OIS actuator.

[0084] In one embodiment, referring to FIG. 4, the first OIS actuator may include a first OIS coil (522) and a first OIS magnet (521). In one embodiment, the first OIS magnet (521) may be disposed on a slider (410) movably coupled to the first carrier (340). In one embodiment, referring to FIGS. 3B and 4, the first OIS magnet (521) may be disposed on a back surface (e.g., a surface facing the -Z direction of FIG. 4) of the slider (410) such that at least a portion of the first OIS coil (522) disposed on a flexible printed circuit board (370) may face the first OIS coil (522).

[0085] In one embodiment, referring to FIG. 4, the first OIS coil (522) is electrically connected to a flexible printed circuit board (370) disposed on the second carrier (350) and at least a portion of which may face the first OIS magnet (521). In one embodiment, the first carrier (340) may be moved in a second axial direction substantially perpendicular to the optical axis through an electromagnetic force (e.g., Lorentz force) acting between the first OIS coil (522) and the first OIS magnet (521). For example, the first carrier (340) may be moved in the second axial direction together with the slider (410) based on an electromagnetic force acting in the second axial direction on a slider (410) disposed below the first carrier (340) through the first OIS magnet (521) and the first OIS coil (522). Accordingly, an electromagnetic effect is induced between the first OIS coil (522) and the first OIS magnet, and the first carrier (340) can move in the second axial direction with respect to the second carrier (350) and / or the camera housing (360) to perform an optical image stabilizer function of correcting image shake.

[0086] In one embodiment, referring to FIG. 4 and FIGS. 6B, 7A, and 7B described below, the first OIS magnet (521) may be arranged such that the N pole (521a) and the S pole (521b) face the first OIS coil (522). In this case, the first OIS magnet (521) may be moved in parallel to the second axis direction (e.g., the Y axis direction in FIG. 4) with respect to the first OIS coil (522) while maintaining a vertical distance (e.g., a distance in the Z axis direction in FIG. 4) with respect to the first OIS coil (522) through an electromagnetic force (e.g., a Lorentz force) acting on the first OIS coil (522) while being coupled to the slider (410).

[0087] In one embodiment, referring to FIG. 4, the second OIS actuator may include a second OIS coil (532) and a second OIS magnet (531). In one embodiment, the second OIS magnet (531) may be disposed on the first carrier (340). In one embodiment, the second OIS magnet (531) may be disposed on a different portion of the first carrier (340) from a portion where the slider (410) is disposed. For example, the slider (410) may be disposed on a first portion (341) of the first carrier (340) (e.g., the first portion (341) of FIG. 6A) and the second OIS magnet (531) may be disposed on a second portion (342) of the first carrier (340) (e.g., the second portion (342) of FIG. 6A). In one embodiment, the first portion (341) and the second portion (342) of the first carrier (340) may be substantially perpendicular to each other in an extension direction. In one embodiment, the second OIS magnet (531) may be disposed on a back surface (e.g., a surface facing the -Z direction of FIG. 4) of the second portion (342) so as to face at least a portion of the second OIS coil (532) disposed on the flexible printed circuit board (370).

[0088] In one embodiment, the second OIS coil (532) is electrically connected to a flexible printed circuit board (370) disposed on the second carrier (350) and at least a portion of the second OIS magnet (531) may face the second OIS magnet. In one embodiment, the second carrier (350) may move in the first axial direction through an electromagnetic force (e.g., Lorentz force) acting between the second OIS coil (532) and the second OIS magnet (531). Accordingly, an electromagnetic effect is induced between the second OIS coil (532) and the second OIS magnet, and the first carrier (340) may move in the first axial direction relative to the second carrier (350) and / or the camera housing (360) to perform an optical image stabilizer function that compensates for image shake.

[0089] In one embodiment, referring to FIG. 4 and FIGS. 6A to 7B described below, the second OIS magnet (531) may be arranged such that the N pole (531a) and the S pole (531b) face the second OIS coil (532). In this case, the second OIS magnet (531) may be moved in parallel to the first axis direction (e.g., the X-axis direction in FIG. 4) with respect to the second OIS coil (532) while maintaining a vertical distance (e.g., a distance in the Z-axis direction in FIG. 4) with respect to the second OIS coil (532) through an electromagnetic force (e.g., a Lorentz force) acting on the second OIS coil (532) while being coupled to the first carrier (340).

[0090] In one embodiment, with reference to FIG. 4 and FIG. 7B described below, at least one AF ball (b3) may be placed between the second carrier (350) and the camera housing (360). In one embodiment, the AF ball (b3) may guide movement of the second carrier (350) when the second carrier (350) moves relative to the camera housing (360) through an electromagnetic force (e.g., Lorentz force, solenoid force) between the AF magnet (541) and the AF coil (542). For example, the AF ball (b3) may guide movement of the second carrier (350) in the direction of the optical axis (e.g., the Z-axis of FIG. 4) relative to the camera housing (360). In one embodiment, referring to FIG. 4, the AF ball (b3) may be positioned in a guide groove (not shown) formed to substantially extend in the optical axis direction (e.g., the Z-axis direction of FIG. 4) in at least one of the camera housing (360) and the second carrier (350). In one embodiment, the guide grooves formed in each of the camera housing (360) and the second carrier (350) may be positioned on both sides of the AF magnet (541).

[0091] According to one embodiment, at least one OIS ball (b2) may be positioned between the first carrier (340) and the second carrier (350), as illustrated in FIG. 4. In one embodiment, the OIS ball (b2) may guide movement of the first carrier (340) in the first axis and / or the second axis when the first carrier (340) is moved relative to the second carrier (350) and / or the camera housing (360) via the electromagnetic force of the first OIS actuator and / or the second OIS actuator.

[0092] In one embodiment, there may be at least three OIS balls (b2), and they may be positioned at positions corresponding to the four corners of the first carrier (340) and the second carrier (350), which are substantially rectangular in shape. In one embodiment, the first carrier (340) and the second carrier (350) may each have a guide groove (not shown) formed in which the OIS balls (b2) are positioned. The OIS balls (b2) may be positioned in the guide grooves formed in the first carrier (340) and the second carrier (350) to guide movement of the first carrier (340) in the first axial direction and / or the second axial direction relative to the second carrier (350) and / or the camera housing (360).

[0093] FIG. 5 is an exploded perspective view of an aperture module according to one embodiment of the present disclosure, illustrating a coupling relationship between a rotator and a slider. FIG. 6A is a rear view of a first carrier according to one embodiment of the present disclosure. FIG. 6B is a drawing of a drive magnet and a first OIS magnet arranged on a rear surface of a slider according to one embodiment of the present disclosure. FIG. 7A is a drawing of a coupling relationship between a first carrier and a slider according to one embodiment of the present disclosure. FIG. 7B is a drawing of a flexible printed circuit board connected to a drive coil, a first OIS coil, and a second OIS coil arranged on a second carrier according to one embodiment of the present disclosure.

[0094] According to one embodiment, the camera module (300) may include an aperture module (400), as illustrated in FIGS. 3A, 3B, and 4 described above. In one embodiment, the aperture module (400) is at least partially coupled to the lens assembly (310) and may move together with the lens assembly (310). For example, the aperture module (400) may move together with the lens assembly (310) when the second carrier (350) moves in the optical axis direction (e.g., the Z-axis direction in FIG. 4) relative to the camera housing (360) for focus adjustment of the lens (312), and when the first carrier (340) moves in the first-axis direction (e.g., the X-axis direction in FIG. 4) and / or the second-axis direction (e.g., the Y-axis direction in FIG. 4) relative to the second carrier (350) for image shake correction.

[0095] In one embodiment, referring to FIGS. 3A, 3B, 4, and 5 described above, the aperture module (400) may include a base (401), a rotator (402), a plurality of plates (403), and an aperture cover (404). The aperture module (400) may have at least one of the above-described components omitted or at least one component added.

[0096] In one embodiment, referring to FIG. 5, the aperture module (400) may be assembled sequentially with a base (401), a rotator (402), a plurality of plates (403), and an aperture cover (404). In one embodiment, the aperture cover (404) may be coupled to the lens assembly (310) so as to cover at least a portion of the plates (403), the rotator (402), and the base (401). In one embodiment, the base (401) may be coupled to an upper portion of the lens assembly (310). In one embodiment, the base (401) may be at least partially open to accommodate a lens (312) of the lens assembly (310). In one embodiment, the rotator (402) may be rotatably coupled to the base (401). In one embodiment, the rotator (402) is coupled with a slider (410) disposed at the bottom of the first carrier (340) and can rotate with respect to the base (401) based on movement of the slider (410) with respect to the first carrier (340). In one embodiment, a plurality of plates (403) can be coupled to the rotator (402). In one embodiment, the plurality of plates (403) can form an incident area (A) corresponding to at least a portion of the lens (312). In one embodiment, the incident area (A) can be an area where light enters the lens (312). In one embodiment, the plates (403) are coupled to the rotator (402), and the size of the incident area (A) can be changed as the position between the plates (403) changes based on rotation of the rotator (402). In summary, the amount of light entering the lens (312) can be adjusted based on the rotation of the rotator (402).

[0097] In one embodiment, referring to FIG. 5, the slider (410) may include a body portion (411), a coupling portion (412) protruding from the body portion (411), and a protrusion portion (413) formed on the coupling portion (412). In one embodiment, the body portion (411) may be a portion that is positioned between the first carrier (340) and the bearing ball (b1). The coupling portion (412) may compensate for a gap between the rotator (402) positioned on the upper portion of the lens assembly (310) and the body portion (411) of the slider (410) positioned on the lower portion of the first carrier (340). In one embodiment, the slider (410) can be coupled with the rotator (402) as the protrusion (413) formed in the coupling portion (412) is coupled to the coupling groove (4022) formed in the coupling portion (4021) of the rotator (402). Accordingly, the rotator (402) can rotate with respect to the base (401) coupled to the lens assembly (310) based on the movement of the slider (410) in the first axial direction (e.g., the X-axis direction of FIG. 5) with respect to the first carrier (340). As described above, the plates (403) can change the size of the incident area (A) based on the rotation of the rotator (402) to control the amount of light entering the lens (312).

[0098] In one embodiment, referring to FIG. 5, the slider (410) may include a first guide groove (421) in which a bearing ball (b1) is arranged. In one embodiment, the first guide groove (421) may be extended in the first axial direction from the body portion (411) of the slider (410) such that the slider (410) may move only in the first axial direction with respect to the first carrier (340) via the bearing ball (b1). In one embodiment, the first guide groove (421) may include a first-first guide groove (421a) and a first-second guide groove (421b) facing the first-first guide groove (421a). In one embodiment, the first-first guide grooves (421a) may be aligned in the X-axis direction of FIG. 5. The 1-2 guide grooves (421b) are aligned in the X-axis direction of FIG. 5 and can face the 1-1 guide grooves (421a).

[0099] In one embodiment, referring to FIG. 6A, the first carrier (340) may include a second guide groove (422) in which a bearing ball (b1) is arranged. In one embodiment, the second guide groove (422) may be formed to extend in the first axial direction from the first portion (341) of the first carrier (340). In one embodiment, the first guide groove (421) and the second guide groove (422) may face each other when the slider (410) is arranged in the first portion (341) of the first carrier (340). In one embodiment, the second guide groove (422) may include a 2-1 guide groove (422a) and a 2-2 guide groove (422b) facing the 2-1 guide groove (422a). In one embodiment, the 2-1 guide grooves (422a) may be aligned in the X-axis direction of FIG. 6A. The 2-2 guide grooves (422b) are aligned in the X-axis direction of FIG. 6 and can face the 2-1 guide grooves (422a).

[0100] In one embodiment, referring to FIGS. 5 and 6A, the spacing between the first-first guide groove (421a) and the first-second guide groove (421b) and the spacing between the second-first guide groove (422a) and the second-second guide groove (422b) may be different from each other due to tolerances in the manufacturing process, etc. In one embodiment, any one of the first-first guide groove (421a), the first-second guide groove (421b), the second-first guide groove (422a), and the second-second guide groove (422b) may be formed as a 'U'-shaped groove. For example, any one of the eight grooves formed in the slider (410) and the first carrier (340) may be formed as a 'U'-shaped groove. The bearing ball (b1) located inside the 'U' shaped groove can move inside the 'U' shaped groove, and thus can compensate for the difference in the gap between the 1-1 guide groove (421a) and the 1-2 guide groove (421b) and the gap between the 2-1 guide groove (422a) and the 2-2 guide groove (422b). In addition, since only one of the eight grooves formed in the slider (410) and the first carrier (340) is formed as a 'U' shaped groove, the slider (410) can move in a straight line with respect to the first carrier (340) via the bearing ball (b1).

[0101] In one embodiment, referring to FIGS. 6A, 6B, and 7A, the first carrier (340) may include a receiving groove (343) formed in the first portion (341). In one embodiment, the engaging portion (412) of the slider (410) may be positioned in the receiving groove (343) of the first carrier (340) and engaged with the fastening portion (4021) of the rotator (402). In one embodiment, the receiving groove (343) may limit movement of the slider (410) in the first axial direction. For example, the first axial length of the receiving groove (343) (e.g., the X-axis length in FIG. 6A) may be equal to the sum of the width of the engaging portion (412) (e.g., the X-axis length in FIG. 5) and the first axial movement distance of the slider (410).

[0102] In one embodiment, referring to FIGS. 6B, 7A, and 7B, the drive magnet (511) may be disposed on a back surface of the slider (410) (e.g., a surface facing the -Z direction in FIG. 7A) so as to at least partially face the drive coil (512). In one embodiment, the drive magnet (511) may be disposed such that the N pole (511a) and the S pole (511b) face the drive coil (512). In this case, the drive magnet (511) may be moved in a first axial direction (e.g., the X-axis direction in FIG. 7A) parallel to the drive coil (512) while maintaining a vertical distance (e.g., a distance in the Z-axis direction in FIGS. 7A and 7B) with respect to the drive coil (512) through an electromagnetic force (e.g., a Lorentz force) acting on the drive coil (512) while being coupled to the slider (410).

[0103] In one embodiment, referring to FIGS. 6B and 7A, the drive magnet (511) and the first OIS magnet (521) may be arranged on the slider (410). In one embodiment, the direction in which the N pole (511a) and the S pole (511b) of the drive magnet (511) are arranged and the direction in which the N pole (521a) and the S pole (511b) of the first OIS magnet (521) are arranged on the slider (410) may be different from each other. For example, the direction in which the N pole (511a) and the S pole (511b) of the drive magnet (511) are arranged and the direction in which the N pole (521a) and the S pole (521b) of the first OIS magnet (521) are arranged may be perpendicular to each other. In other words, the extension direction (e.g., the Y-axis direction in FIG. 7a) of the gap (e.g., the part where no polarity exists) between the N pole (511a) and the S pole (511b) of the driving magnet (511) and the extension direction (e.g., the X-axis direction in FIG. 7a) of the gap between the N pole (521a) and the S pole (521b) of the first OIS magnet (521) may be perpendicular to each other. Based on the arrangement relationship between the driving magnet (511) and the first OIS magnet (521) described above, the movement direction (e.g., the first axial direction) of the slider (410) and the movement direction (e.g., the second axial direction) of the first OIS carrier may be perpendicular to each other. Therefore, the movement of the slider (410) and the movement of the first carrier (340) may not affect each other. For example, the position value of the first OIS magnet (521) detected by a Hall sensor (e.g., the second Hall sensor (602) of FIGS. 4 and 7B) placed on a flexible printed circuit board (370) so as to face the first OIS magnet (521) may not change even if the slider (410) moves in the first axis direction.

[0104] In one embodiment, referring to FIG. 6B, the drive magnet (511) and the first OIS magnet (521) may be formed integrally and may be polarized to have at least two N poles and two S poles. In this case, the magnet may be divided into a drive magnet (511) region (S1) and a first OIS magnet (521) region (S2). However, this is an example, and as illustrated in FIG. 7A, the drive magnet (511) and the first OIS magnet (521) may be formed separately and arranged adjacently on the slider (410).

[0105] In one embodiment, the camera module (300) (e.g., the camera module (180) of FIG. 1) may include an AF position detection sensor (not shown) that detects the displacement and position of the second carrier (350). In one embodiment, the AF position detection sensor may be a hall sensor. In one embodiment, the AF position detection sensor may be disposed inside (e.g., in a hole or center) of the AF coil (542) and may be electrically connected to the processor (120) via a flexible printed circuit board (370) or another flexible printed circuit board.

[0106] In one embodiment, the AF position detection sensor may face at least a portion of the AF magnet (541). In one embodiment, referring to FIG. 4, the AF coil (542) may be disposed on one surface of the camera housing (360) to face the AF magnet (541) disposed on the second carrier (350). In one embodiment, the AF magnet (541) may be moved in the optical axis direction together with the second carrier (350) as the second carrier (350) moves in the optical axis direction (e.g., the Z-axis direction of FIG. 4) to adjust the focus of the lens (312). The AF position detection sensor may detect a change in magnetic flux of the AF magnet (541) according to the movement of the AF magnet (541) to detect a displacement and / or position of the second carrier (350) in the optical axis direction. The processor (120) may control the AF coil (542) based on position information of the second carrier (350) detected by the AF position detection sensor. For example, the processor (120) can control the amount of current flowing through the AF coil (542) to control the strength of the electromagnetic force generated in the AF coil (542). Accordingly, the relative position between the AF magnet (541) and the AF coil (542) can be controlled.

[0107] In one embodiment, the AF coil (542) may be disposed on one surface of the second carrier (350) to face the AF magnet (541) disposed on one surface of the camera housing (360). In one embodiment, the AF coil (542) may be moved in the optical axis direction together with the second carrier (350) as the second carrier (350) moves in the optical axis direction (e.g., the Z-axis direction of FIG. 4) to adjust the focus of the lens (312). The AF position detection sensor may be disposed inside the AF coil (542) or on one surface of the camera housing (360) to face the AF magnet (541). The AF position detection sensor may detect a change in magnetic flux of the AF magnet (541) according to the movement of the AF coil (542) to detect a displacement and / or position of the second carrier (350) in the optical axis direction. The processor (120) can control the AF coil (542) based on the position information of the second carrier (350) detected through the AF position detection sensor. For example, the processor (120) can control the amount of current flowing in the AF coil (542) to control the strength of the electromagnetic force generated in the AF coil (542). Accordingly, the relative position between the AF magnet (541) and the AF coil (542) can be controlled.

[0108] In one embodiment, referring to FIG. 7B, the camera module (300) may include a slider position detection sensor (601) that detects a displacement or position of the slider (410). In one embodiment, the slider position detection sensor (601) may be a Hall sensor. Hereinafter, the slider position detection sensor (601) will be described as a first Hall sensor (601). In one embodiment, the first Hall sensor (601) may be disposed inside (e.g., a hole or a center) of the drive coil (512) and may be electrically connected to the flexible printed circuit board (370). In one embodiment, at least a portion of the first Hall sensor (601) may face the drive magnet (511). In one embodiment, the drive magnet (511) may be moved in a first axial direction (e.g., the X-axis direction of FIG. 7B) with respect to the first carrier (340) together with the slider (410) to adjust the opening state of the aperture module (400). The first Hall sensor (601) can detect a change in the magnetic flux of the driving magnet (511) according to the movement of the driving magnet (511) to detect the displacement and / or position of the slider (410) in the first axial direction. The processor (120) can control the driving coil (512) based on the position information of the slider (410) detected through the first Hall sensor (601). For example, the processor (120) can control the amount of current flowing in the driving coil (512) to control the strength of the electromagnetic force generated in the driving coil (512). Therefore, the relative position between the driving magnet (511) and the driving coil (512) can be controlled.

[0109] In one embodiment, referring to FIG. 7B, the camera module (300) may include a first OIS position detection sensor (602) that detects a displacement or position of the first carrier (340). In one embodiment, the first OIS position detection sensor (602) may be a Hall sensor. Hereinafter, the first OIS position detection sensor (602) will be described as a second Hall sensor (602). In one embodiment, the second Hall sensor (602) may be disposed inside (e.g., in a hole or at the center) of the first OIS coil (522) and may be electrically connected to the flexible printed circuit board (370). At least a portion of the second Hall sensor (602) may face the first OIS magnet (521). In one embodiment, the first OIS magnet (521) may be moved in a second axis direction (e.g., the Y-axis direction of FIG. 7B) with respect to the second carrier (350) to compensate for image shake. The second Hall sensor (602) can detect a change in the magnetic flux of the first OIS magnet (521) according to the movement of the first OIS magnet (521) to detect a displacement and / or position of the first carrier (340) in the second axial direction. The processor (120) can control the first OIS coil (522) based on the position information of the first carrier (340) detected through the second Hall sensor (602). For example, the processor (120) can control the strength of the electromagnetic force generated in the first OIS coil (522) by controlling the amount of current flowing in the first OIS coil (522). Therefore, the relative position between the first OIS magnet (521) and the first OIS coil (522) can be controlled.

[0110] In one embodiment, referring to FIG. 7B, the camera module (300) may include a second OIS position detection sensor (603) that detects a displacement or position of the first carrier (340). In one embodiment, the second OIS position detection sensor (603) may be a Hall sensor. Hereinafter, the second OIS position detection sensor (603) will be described as a third Hall sensor (603). In one embodiment, the third Hall sensor (603) may be disposed inside (e.g., in a hole or center) of the second OIS coil (532) and may be electrically connected to the flexible printed circuit board (370). At least a portion of the third Hall sensor (603) may face the second OIS magnet (531). In one embodiment, the second OIS magnet (531) may be moved in a first axial direction with respect to the second carrier (350) to compensate for image shake. The third Hall sensor (603) can detect a change in the magnetic flux of the second OIS magnet (531) according to the movement of the second OIS magnet (531) to detect a displacement and / or position of the first carrier (340) in the first axial direction. The processor (120) can control the second OIS coil (532) based on the position information of the first carrier (340) detected through the third Hall sensor (603). For example, the processor (120) can control the strength of the electromagnetic force generated in the second OIS coil (532) by controlling the amount of current flowing in the second OIS coil (532). Therefore, the relative position between the second OIS magnet (531) and the second OIS coil (532) can be controlled.

[0111] In one embodiment, referring to FIG. 7b, the second OIS coil (532) may include a second-first OIS coil (532a) and a second-second OIS coil (532b). In one embodiment, the second-first OIS coil (532a) and the second-second OIS coil (532b) may be arranged substantially side by side in the second carrier (350). In one embodiment, when currents of different magnitudes or directions flow through the second-first OIS coil (532a) and the second-second OIS coil (532b), a torque may be generated in the second OIS magnet (531), and in this case, the first carrier (340) may rotate with respect to the camera housing (360). In addition, the first carrier (340) can rotate about the optical axis (e.g., the Z-axis of FIG. 7b) relative to the second carrier (350) based on acceleration, external force, image shake correction, auto-focus adjustment, etc. applied to the camera module (180, 300). By individually controlling the current of the 2-1 OIS coil (532a) and the 2-2 OIS coil (532b), the rotational movement of the first carrier (340) can be restricted.

[0112] In one embodiment, the second OIS coil (532) may be a single coil (not shown) in a closed-loop configuration rather than a plurality of coils. In this case, a middle guide (e.g., a guide member) (not shown) may be placed between the first carrier (340) and the second carrier (350) to prevent the first carrier (340) from rotating about the optical axis (e.g., the Z axis in FIG. 7B) with respect to the camera housing (360). In one embodiment, the middle guide may prevent the first carrier (340) from rotating when the first carrier (340) moves in the first axis direction (e.g., the X axis direction in FIG. 7B) or the second axis direction (e.g., the Y axis direction in FIG. 7B) for image shake correction. For example, the middle guide may prevent the first carrier (340) from rotating about the optical axis (e.g., the roll axis, the Z axis in FIG. 7B) with respect to the camera housing (360).

[0113] FIG. 8A is a diagram illustrating an operation process of an OIS control unit and an aperture control unit according to an embodiment of the present disclosure. FIG. 8B is a diagram illustrating position values ​​of a slider and a first carrier detected by a Hall sensor when an aperture value is fixed according to an embodiment of the present disclosure. FIG. 8C is a diagram illustrating position values ​​of a slider and a first carrier detected by a Hall sensor when an aperture value change signal is generated according to an embodiment of the present disclosure.

[0114] In one embodiment, referring to FIG. 8A, the OIS control unit (301) (e.g., the image stabilizer (240) of FIG. 2) may obtain movement information of the electronic device (101) detected by a sensor module (e.g., the sensor module (176), a gyro sensor, an acceleration sensor of FIG. 1) of the electronic device (101) (S101), and correct image shake based on the movement information. For example, the OIS control unit (301) may calculate a direction in which the movement is offset and a target position value of the first carrier (340) to be moved based on the movement information. The OIS control unit (301) may apply a current to the first OIS coil (522) and / or the second OIS coil (532) to move the first carrier (340) in the first axis and / or the second axis direction (S102). In one embodiment, the OIS control unit (301) may receive the target position value of the first carrier (340) calculated from the processor (120) and control the first OIS coil (522) and / or the second OIS coil (532).

[0115] In one embodiment, the first position feedback control unit (303) and the second position feedback control unit (304) can determine whether the first carrier (340) has moved to the target position value transmitted from the OIS control unit (301). In one embodiment, the first position feedback control unit (303) and the second position feedback control unit (304) may be separate components from the second Hall sensor (602) and / or the third Hall sensor (603), and may be included in the second Hall sensor (602) and / or the third Hall sensor (603). In one embodiment, the first position feedback control unit (303) and the second position feedback control unit (304) may be included in the OIS control unit (301).

[0116] In one embodiment, referring to FIG. 8A, the second Hall sensor (602) and the third Hall sensor (603) can detect the movement position of the first carrier (340) in the first axis and / or the second axis direction based on the control of the OIS control unit (301). In one embodiment, feedback on the movement of the first carrier (340) can be provided through the first position feedback control unit (303) and the second position feedback control unit (304). In one embodiment, the first position feedback control unit (303) and the second position feedback control unit (304) can confirm the actual position of the first carrier (340) detected by the second Hall sensor (602) and the third Hall sensor (603) and compare it with the target position value of the first carrier (340). In one embodiment, the first position feedback control unit (303) and the second position feedback control unit (304) may calculate an error between the target position value of the first carrier (340) and the actual position value of the first carrier (340) detected by the Hall sensors (e.g., the second Hall sensor (602) and the third Hall sensor (603)) and control the first OIS coil (522) and / or the second OIS coil (532) to move the first carrier (340) so that the first carrier (340) reaches the target position value. In one embodiment, the movement position feedback of the first carrier (340) may be performed through the OIS control unit (301). For example, the OIS control unit (301) can control the first OIS coil (522) and / or the second OIS coil (532) based on the position value error of the first carrier transmitted from the first position feedback control unit (303) and the second position feedback control unit (304) to move the first carrier (340) to the target position value.

[0117] In one embodiment, referring to FIG. 8A, the aperture control unit (302) may adjust the opening state of the aperture module (400) based on the received aperture opening / closing command (P1), based on an aperture value manually input in the camera application or an aperture value automatically calculated based on ambient lighting. In one embodiment, the aperture module may control the drive coil (512) to move the slider (410) in the first axial direction with respect to the first carrier (340) to adjust the opening state of the aperture module (400) based on the aperture value. In one embodiment, the aperture control unit (302) may calculate a target position value of the slider (410) to reach the input or calculated aperture value. In one embodiment, the target position value of the slider (410) may be a sum of the target position value of the first axial direction of the first carrier (340) and the position value of the slider (410). For example, when the aperture module (400) is in the maximum opening state, minimum opening state, and / or an open state between them, the position value of the slider (410) may have a certain position value (e.g., 0 to 50). In this case, the target position value of the slider (410) may be a value obtained by adding the position value of the first axial direction of the first carrier (340) and the position value of the slider (410) (e.g., 0 to 50). The position value (0 to 50) of the slider (410) described above is an example, and the position value may be transformed into various numbers.

[0118] In one embodiment, the third position feedback control unit (305) can determine whether the slider (410) has moved to the target position value transmitted from the aperture control unit (302). In one embodiment, the third position feedback control unit (305) can be a separate component from the first Hall sensor (601) and can be included in the first Hall sensor (601). In one embodiment, the third position feedback control unit (305) can be included in the aperture control unit (302).

[0119] In one embodiment, the first Hall sensor (601) can detect the movement position of the slider (410) in the first axis direction. In one embodiment, feedback on the movement of the slider (410) can be provided through the third position feedback control unit (305). In one embodiment, the third position feedback control unit (305) can check the actual position of the slider (410) detected by the first Hall sensor (601) and compare it with a target position value of the slider (410). In one embodiment, the third position feedback control unit (305) can calculate an error between the target position value of the slider (410) and the actual position value of the slider (410) detected by the first Hall sensor (601), and control the drive coil (512) to move the slider (410) so that the slider (410) reaches the target position value. In one embodiment, feedback on the movement position of the slider (410) can be provided through the aperture control unit (302). For example, the aperture control unit (302) can control the drive coil (512) based on the position value error of the slider (410) transmitted from the third position feedback control unit (305) to move the slider (410) to the target position value.

[0120] In one embodiment, when the open state of the aperture module (400) is maintained, the position value of the slider (410) detected by the first hall sensor (601) may be the same as the first axial target position value of the first carrier (340).

[0121] In one embodiment, the direction in which the slider (410) moves to adjust the open state of the aperture module (400) and the direction in which the first carrier (340) moves according to the operation of the second OIS actuator may be the same in the first axial direction. In one embodiment, when the size of the incident area (A) of the aperture module (400) is fixed, the position of the slider (410) relative to the first carrier (340) may be fixed. Referring to FIG. 8B, when the position of the slider (410) is fixed with respect to the first carrier (340), when the first carrier (340) moves in the first axial direction based on the driving of the second OIS actuator (e.g., the second OIS magnet (531) and the second OIS coil (532)), the first position value (e.g., the position value in the first axial direction, the displacement value) of the driving magnet (511) detected by the first Hall sensor (601) and the second position value (e.g., the position value in the first axial direction, the displacement value) of the second OIS magnet (531) detected by the third Hall sensor (603) may be the same. For example, the first axial direction movement amount of the driving magnet (511) and the first axial direction movement amount of the second OIS magnet (531) may be the same.

[0122] Referring to FIG. 8B, the processor (120) can check the first position value (e.g., first displacement value) of the driving magnet (511) detected by the first Hall sensor (601) (S103) and check the third position value (e.g., second displacement value) of the second OIS magnet (531) detected by the third Hall sensor (603) (S104). The processor (120) can determine whether the camera module (300) is operating normally by checking whether the first position value and the third position value are the same (S105). For example, when the position of the slider (410) is fixed with respect to the first carrier (340), if the first position value and the third position value are the same, the camera module (300) may be operating normally.

[0123] In one embodiment, referring to FIG. 8C, the processor (120) may calculate an aperture value according to the current light conditions in the camera module (300) (e.g., the camera module (180) of FIG. 1, the aperture control unit (302)) to control the opening state of the aperture module (400). The aperture value may be a numerical value indicating the degree to which the incident area (A) is opened. The processor (120) may control the position of the slider (410) based on the detection of an aperture value change signal. The aperture value change signal may be generated from the camera module (300) or the aperture control unit (302). In one embodiment, the aperture control unit (302) may move the slider (410) to control the aperture value of the aperture module (400). In one embodiment, the memory (130) may match and store an aperture value and a position value (e.g., a displacement value) of the slider (410). The aperture control unit (302) can check the position value of the slider (410) to reach the calculated aperture value in the memory (130) and control the drive coil (512) to move the slider (410) to the corresponding position.

[0124] In one embodiment, referring to FIG. 8C, the aperture control unit (302) can check the position value (e.g., the position value in the first axis direction, the third position value, the third displacement value) of the slider (410) that matches the changed aperture value in the memory (130) based on the detection of the aperture value change signal of the aperture module (400) (S201) (S202). The aperture control unit (302) can calculate the movement amount of the slider to reach the position value for reaching the changed aperture value from the current position of the slider (410).

[0125] As described above through FIG. 8B, before the aperture value is changed, the slider (410) is fixed to the first carrier (340), so the position value (e.g., displacement value) of the driving magnet (511) detected by the first Hall sensor (601) and the position value (e.g., displacement value) of the second OIS magnet (531) detected by the third Hall sensor (603) may be the same. The aperture control unit (302) can check the position value (e.g., position value in the first axis direction, fourth position value, fourth displacement value) of the second OIS magnet (531) detected by the third Hall sensor (603) (S203) to check the position of the driving magnet (511) before moving in the first axis direction. In one embodiment, the aperture control unit (302) can control the drive coil (512) so that the slider (410) reaches a third position value from a fourth position value, which is a position before the aperture value change (S204). In one embodiment, the position value (e.g., the third position value) of the drive magnet (511) detected by the first Hall sensor (601) according to the movement of the slider (410) in the first axial direction can be a value obtained by adding the movement amount of the slider (410) to the fourth position value of the second OIS magnet (531) detected by the third Hall sensor (603).

[0126] In the above description, the OIS control unit (301) and the aperture control unit (302) were described as separate components from the processor (120). However, in one embodiment, the OIS control unit (301) and the aperture control unit (302) may be part of the processor (120).

[0127] FIGS. 9A and 9B are diagrams illustrating the arrangement relationship between a pulling yoke and a slider according to one embodiment of the present disclosure. FIG. 10 is a cross-sectional view taken along line AA of FIG. 3B according to one embodiment of the present disclosure.

[0128] According to one embodiment, a pulling yoke (380) may be disposed between the first part (341) of the first carrier (340) and the slider (410), as illustrated in FIGS. 9A and 9B. In one embodiment, the pulling yoke (380) may extend in the first axial direction and may be disposed to cover the slider (410). For example, the pulling yoke (380) may be formed with at least a portion of a planar shape to cover the slider (410). For example, referring to FIG. 10, when the camera module (300) (e.g., the camera module (180) of FIG. 1) is viewed in a vertical direction, the pulling yoke (380) - the slider (410) - the first OIS magnet (521) - the first OIS coil (522) may be stacked in that order. In one embodiment, the pulling yoke (380) may be formed in a shape in which both ends are bent, as illustrated in FIG. 9A, to cover the ends of the slider (410). In one embodiment, referring to FIG. 3A, the pulling yoke (380) may be positioned so as not to overlap the first guide groove (421) and the second guide groove (422) in which the bearing ball (b1) is positioned, when the camera module (300) is viewed in a vertical direction (e.g., the -Z direction of FIG. 9A).

[0129] According to one embodiment, as illustrated in FIG. 10, a holding yoke (390) may be disposed at a lower portion of a flexible printed circuit board (370), at least a portion of which faces a pulling yoke (380). In one embodiment, the holding yoke (390) is disposed on the second carrier (350), and may overlap with the driving magnet (511), the driving coil (512), the first OIS magnet (521), and the first OIS coil (522) when the camera module (300) is viewed in a vertical direction (e.g., the -Z direction of FIG. 10).

[0130] In one embodiment, a driving magnet (511), a driving coil (512), a first OIS magnet, and a first OIS coil (522) may be arranged between a pulling yoke (380) and a holding yoke (390). In one embodiment, the pulling yoke (380) and the holding yoke (390) may prevent the magnetic flux of the driving magnet (511) and the first OIS magnet (521) formed of a metal material from leaking.

[0131] According to one embodiment, the receiving groove (343) formed in the first carrier (340) can limit the movement of the slider (410) in the first axial direction. Hereinafter, the maximum points at which the slider (410) can move in the first axial direction within the receiving groove (343) will be described as 'first points' and 'second points'. In one embodiment, the first points and the second points are located in opposite directions and may be limit positions at which the slider (410) can move. In one embodiment, the incident area (A) of the aperture module (400) may have a minimum size when the slider (410) reaches the first point, and may have a maximum size when the slider (410) reaches the second point. In other words, the aperture module (400) may be in a minimum open state when the slider (410) is in the first point, and may be in a maximum open state when the slider (410) is in the second point.

[0132] According to one embodiment, the magnitude of the suction force acting on the pulling yoke (380) may increase as the drive magnet (511) moves toward the first point or the second point at which the slider (410) can move to the maximum in the first axial direction. In one embodiment, the suction force acting between the drive magnet (511) and the pulling yoke (380) at the first point and the second point may be greater than the suction force acting between the drive magnet (511) and the holding yoke (390). Therefore, when the slider (410) moves toward the first point and the second point, the position with respect to the first carrier (340) may be fixed through the suction force acting between the drive magnet (511) and the pulling yoke (380).

[0133] FIG. 11A is a drawing of an aperture module with the aperture module minimally opened, according to one embodiment of the present disclosure. FIG. 11B is a drawing of an aperture module with the aperture module maximally opened, according to one embodiment of the present disclosure.

[0134] In the following description, FIG. 11a may be a drawing of an aperture module (400) in a state where it is minimally opened when the slider (410) reaches the first point. FIG. 11b may be a drawing of an aperture module (400) in a state where it is maximally opened when the slider (410) reaches the second point.

[0135] In one embodiment, the aperture module (400) of FIGS. 11A and 11B may be an aperture module (400) that can only open to the maximum or minimum as the slider (410) moves to the first or second position, and may not be an aperture module (400) that can open in the middle between the maximum and minimum openings (e.g., a size of the incident area (A) between the minimum and maximum). In this case, the plates (403) of the aperture module (400) may be composed of two. However, the present invention is not limited thereto, and the number of plates (403) may be variously modified.

[0136] According to one embodiment, as illustrated in FIGS. 11A and 11B, when the slider (410) is moved to the first point or the second point, the position relative to the first carrier (340) can be fixed through an attractive force acting between the driving magnet (511) and the pulling yoke (380). Accordingly, the aperture module (400) can maintain the maximum opening state or the minimum opening state of the aperture module (400) without separate control.

[0137] FIG. 12a is a drawing of an aperture module in a minimally opened state according to one embodiment of the present disclosure. FIG. 12b is a drawing of an aperture module in a mid-open state according to one embodiment of the present disclosure. FIG. 12c is a drawing of an aperture module in a maximally opened state according to one embodiment of the present disclosure.

[0138] The following description may be a description of an aperture module (700) different from that of FIGS. 11A and 11B. In one embodiment, the aperture module (700) of FIGS. 12A to 12C may be an aperture module (700) in which the size of the incident area (A) may be continuously changed. For example, the aperture module (700) of FIGS. 12A to 12C may be capable of continuously changing the size of the incident area (A) from a minimum opening to a maximum opening based on the movement of the slider (410).

[0139] In one embodiment, FIG. 12a may be a drawing of an aperture module (700) in a minimally opened state when the slider (410) reaches a first point.

The aperture module (700) may have at least one of the above-described components omitted or at least one component added. In one embodiment, the remaining components of the aperture module (700) excluding the plurality of plates (703) may be substantially the same as the configuration of the aperture module (400) of FIG. 4.

[0141] In one embodiment, referring to FIGS. 12A to 12C, the aperture module (700) may include a plurality of plates (703) such that the size of the incident area (A) can be continuously changed based on the first axial movement of the slider (410). For example, the aperture module (700) of FIG. 12A may include more plates (703) than the aperture module (400) of FIG. 11A.

[0142] According to one embodiment of the present disclosure, the aperture module (400, 700) is coupled to the lens assembly (310) and moves together with the lens assembly (310) during auto focus (AF) or image stabilization (optical image stabilizer OIS), so that the center of the incident area (A) formed by the aperture module (400, 700) (e.g., the area where light passes through the aperture module) and the center of the lens (312) can be aligned.

[0143] The technical tasks to be achieved in this document are not limited to the technical tasks mentioned above, and other technical tasks not mentioned will be clearly understood by those with ordinary skill in the technical field to which this document pertains from the description below.

[0160] In one embodiment, the aperture module comprises a base (401, 701) coupled to the upper portion of the lens assembly, a rotator (402, 702) rotatably coupled to the base, and

[0161] The rotator may include a plurality of plates (403, 703) that are coupled to the rotator and form an incident area (A) corresponding to a portion of the lens.

[0163] In one embodiment, the drive magnet may have an N pole (511a) and a S pole (511b) facing the drive coil so as to move parallel to the drive coil while maintaining a vertical distance therebetween. The first OIS magnet may have an N pole (521a) and a S pole (521b) facing the first OIS coil so as to move parallel to the first OIS coil while maintaining a vertical distance therebetween.

[0165] According to various embodiments disclosed in this document, the aperture module (400, 700) can be coupled to the lens assembly (310). Accordingly, the aperture module (400, 700) can move together with the lens assembly (310) during auto-focus adjustment or image stabilization to correct image shake, thereby maintaining the center of the incident area (A) formed by the aperture module (400, 700) and the center of the lens (312) aligned.

[0166] In addition, the camera module (180, 300) may include an aperture module (400, 700) that controls the amount of light of the lens (312). The aperture module (400, 700) is coupled to a slider (410) that can move linearly, and the opening state can be adjusted based on the movement of the slider (410). Meanwhile, the OIS magnet (521) (e.g., the first OIS magnet (521)) used for image shake control and the drive magnet (511) used for controlling the aperture module (400, 700) may be arranged together on the slider (410). Therefore, since the area where the drive magnet (511) and the OIS magnet (521) are arranged is shared, no separate additional space is required for arranging the OIS magnet (521) or the drive magnet (511), and thus the size of the camera module (180, 300) can be reduced.

[0167] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

[0168] According to various embodiments disclosed in this document, the aperture module (400, 700) can be coupled to the lens assembly (310). Accordingly, the aperture module (400, 700) can move together with the lens assembly (310) during auto-focus adjustment or image stabilization to correct image shake, thereby maintaining the center of the incident area (A) formed by the aperture module (400, 700) and the center of the lens (312) aligned.

[0169] In addition, the first OIS magnet (521) of the OIS actuator used for image shake control and the drive magnet (511) used for controlling the open state of the aperture module (400, 700) can be placed together on the slider (410). Accordingly, since the area where the drive magnet (511) and the first OIS magnet (521) are placed is shared, no separate additional space is required for placing the first OIS magnet (511) or the drive magnet (521), and thus the size of the camera module (300) can be reduced.
