Description

Camera devices and optical instruments

[0001] The present embodiment relates to a camera device and an optical device.

[0002] A camera device is a device that takes pictures or videos of a subject, and is installed in optical devices such as smartphones, drones, and vehicles.

[0003] Camera devices are equipped with a shake correction function to prevent the focus from shaking due to the user's hand shaking.

[0004] However, in conventional lens driving devices, the shake correction function is performed through two-axis correction, that is, x-axis shift correction and y-axis shift correction.

[0005] However, recently, there has been a demand for improved performance image stabilization.

[0006] (Patent Document 1) KR 10-2015-0118005 A

[0007] The present embodiment seeks to provide a camera device having an improved performance shake correction function through 4-axis correction.

[0008] In more detail, it is an object of the present invention to provide a camera device that performs a shake correction function through x-axis shift correction, y-axis shift correction, yaw-direction tilt correction, and pitch-direction tilt correction.

[0009] Furthermore, it is intended to provide a camera device in which a substrate that movably supports an image sensor is formed so as not to interfere with driving force.

[0010] In addition, it is intended to provide a camera device that performs compression of a ball that guides tilting of an image sensor through repulsive force.

[0011] In addition, it is intended to provide a camera device with a minimized height in the optical axis direction.

[0012] A camera device according to the present embodiment comprises: a base; a first substrate disposed on the base; an image sensor disposed on the first substrate; a lens disposed on the image sensor; a first driving unit that moves the lens in an optical axis direction; a second driving unit that tilts the image sensor and the lens together about a first axis; and a third driving unit that tilts the image sensor and the lens together about a second axis perpendicular to the first axis, wherein the first substrate includes a body portion on which the image sensor is disposed, and an extension portion extending outward from the body portion, and the extension portion of the first substrate includes a first portion and a second portion that are disposed to face each other, and the first portion of the first substrate and the second portion of the first substrate can overlap each other in a first direction perpendicular to the optical axis direction.

[0013] The extension portion of the first substrate includes a third portion and a fourth portion that are arranged to face each other, and the third portion of the first substrate and the fourth portion of the first substrate can overlap each other in the first direction.

[0014] The first to fourth portions of the first substrate can overlap each other in the first direction.

[0015] At least a portion of each of the first to fourth portions of the first substrate may be arranged parallel to the optical axis direction.

[0016] The extension portion of the first substrate includes a first bend portion connecting the upper end of the first portion and the upper end of the second portion, and a first stiffener of a corresponding shape may be arranged on the first bend portion of the first substrate.

[0017] The extension portion of the first substrate includes a second bend portion connecting one side of the third portion and a side of the second portion, and a third bend portion connecting the other side of the third portion and a side of the fourth portion, and a second stiffener of a corresponding shape may be arranged on the second bend portion of the first substrate, and a third stiffener of a corresponding shape may be arranged on the third bend portion of the first substrate.

[0018] The base may include a first protrusion at least partially disposed between the first portion of the first substrate and the second portion of the first substrate.

[0019] The base may include a second protrusion disposed at least partially between the second portion of the first substrate and the third portion of the first substrate, and a third protrusion disposed between the third portion of the first substrate and the fourth portion of the first substrate.

[0020] The first substrate includes an outer portion on which a connector connected to the outside is arranged, and the extension portion of the first substrate can connect the body portion of the first substrate and the outer portion of the first substrate.

[0021] The camera device includes a sensor base disposed on the base and coupled to the body portion of the first substrate; a first magnet disposed on the base; and a second magnet disposed on the sensor base and positioned below the first magnet, wherein the first magnet and the second magnet may be disposed such that their poles face each other.

[0022] The first surface of the first magnet and the first surface of the second magnet are arranged to face each other, and the area of ​​the first surface of the second magnet may be larger than the area of ​​the first surface of the first magnet.

[0023] The camera device may include a fourth driving unit that moves the lens in a first direction perpendicular to the optical axis direction; and a fifth driving unit that moves the lens in a second direction perpendicular to the optical axis direction and the first direction.

[0024] The fourth driving part includes a fourth coil arranged on the base, and the base includes a protrusion arranged on an upper side of the fourth coil, and when viewed from above, an edge of the upper surface of the fourth coil is covered by the protrusion of the base, and the remaining part of the upper surface of the fourth coil can be opened without being covered by the base.

[0025] The fifth driving unit includes a fifth coil arranged on the base, and the fifth coil includes two coils spaced apart from each other, and when viewed from above, the upper surfaces of the two coils can be opened without being covered by the base.

[0026] An optical device according to the present embodiment may include a main body; a camera device disposed in the main body; and a display disposed in the main body and outputting at least one of an image and an image captured by the camera device.

[0027] Through this embodiment, an improved performance shake correction function can be provided through 4-axis correction.

[0028] In more detail, it is possible to provide a shake correction function with improved performance compared to the conventional two-axis correction through x-axis shift correction, y-axis shift correction, yaw-direction tilt correction, and pitch-direction tilt correction.

[0029] Therefore, clearer photos or videos can be obtained despite the hand shake of the optical device user.

[0030] In addition, the substrate that movably supports the image sensor is formed so as not to interfere with the driving force, so that the size of the magnet and coil that drive the image sensor can be minimized.

[0031] Additionally, the compression state of the ball that guides the tilting of the image sensor can be maintained by the repulsive force between the magnets.

[0032] Additionally, by opening the injection molding on the upper side of the coil, the height of the camera device in the optical axis direction can be minimized.

[0256] Below, the auto focus (AF) operation of the lens driving device according to the present embodiment is described.

[0257] Fig. 31 is a drawing for explaining auto focus operation of a camera device according to the present embodiment.

[0258] The moving part may be positioned at a position spaced apart from both the upper plate (121) of the cover (120) and the base (110) in the initial position where no current is applied to the AF coil (420). At this time, the moving part may include a carrier (340). Furthermore, the moving part may include a carrier (340), a lens, and an AF magnet (410).

[0259] When current is applied to the AF coil (420), the moving part (see A in FIG. 31) can move upward or downward along the optical axis (see B in FIG. 31).

[0260] When a positive current is applied to the AF coil (420), the AF magnet (410) can move upward in the optical axis direction due to the electromagnetic interaction between the AF coil (420) and the AF magnet (410). At this time, the carrier (340) can move upward in the optical axis direction together with the AF magnet (410). Furthermore, the lens can move upward in the optical axis direction together with the carrier (340). Accordingly, the distance between the lens and the image sensor (220) can be changed, so that the focus of the image formed on the image sensor (220) through the lens can be adjusted.

[0261] When a reverse current is applied to the AF coil (420), the AF magnet (410) can move downward in the optical axis direction due to the electromagnetic interaction between the AF coil (420) and the AF magnet (410). At this time, the carrier (340) can move downward in the optical axis direction together with the AF magnet (410). Furthermore, the lens can move downward in the optical axis direction together with the carrier (340). Accordingly, the distance between the lens and the image sensor (220) can be changed, so that the focus of the image formed on the image sensor (220) through the lens can be adjusted.

[0262] Meanwhile, during the movement of the AF magnet (410), the AF sensor (430) can detect the strength of the magnetic field of the AF magnet (410) to detect the amount of movement or position of the lens in the optical axis direction. The amount of movement or position of the lens in the optical axis direction detected by the AF sensor (430) can be used for auto focus feedback control.

[0263]

[0264] Below, the optical image stabilization (OIS) operation of the lens driving device according to the present embodiment is described.

[0265] Fig. 32 is a drawing for explaining the shake correction operation through x-axis shift correction and y-axis shift correction of the camera device according to the present embodiment.

[0266] The moving part can be placed in the initial position without current being applied to the OIS-x coil (512) and the OIS-y coil (522). At this time, the moving part can include a housing (310). Furthermore, the moving part can include a housing (310), a carrier (340), a lens, an OIS-x magnet (511), and an OIS-y magnet (521). The moving part can include a housing (310), a carrier (340), an AF magnet (410), an AF coil (420), a lens, a filter (350), an OIS-x magnet (511), and an OIS-y magnet (521).

[0267] When current is applied to the OIS-x coil (512), the moving part (see A in Fig. 32) can move in the x-axis direction (see B in Fig. 32).

[0268] When current is applied to the OIS-x coil (512), the OIS-x magnet (511) can move in the x-axis direction perpendicular to the optical axis due to the electromagnetic interaction between the OIS-x coil (512) and the OIS-x magnet (511). At this time, the housing (310) can move in the x-axis direction together with the OIS-x magnet (511). Furthermore, the carrier (340) and the lens can move in the x-axis direction together with the housing (310). More specifically, when a positive current is applied to the OIS-x coil (512), the OIS-x magnet (511), the housing (310), the carrier (340), and the lens can move in one direction on the x-axis. Additionally, when reverse current is applied to the OIS-x coil (512), the OIS-x magnet (511), housing (310), carrier (340), and lens can move in the other direction along the x-axis.

[0269] When current is applied to the OIS-y coil (522), the moving part (see A in Fig. 32) can move in the y-axis direction (see C in Fig. 32).

[0270] When current is applied to the OIS-y coil (522), the OIS-y magnet (521) can move in the y-axis direction perpendicular to the optical axis due to the electromagnetic interaction between the OIS-y coil (522) and the OIS-y magnet (521). At this time, the housing (310) and the frame (330) can move in the y-axis direction together with the OIS-y magnet (521). Furthermore, the carrier (340) and the lens can move in the y-axis direction together with the housing (310). More specifically, when a positive current is applied to the OIS-y coil (522), the OIS-y magnet (521), the frame (330), the housing (310), the carrier (340), and the lens can move in one direction on the y-axis. Additionally, when a reverse current is applied to the OIS-y coil (522), the OIS-y magnet (521), frame (330), housing (310), carrier (340), and lens can move in the other direction along the y-axis.

[0271] Meanwhile, the OIS-x sensor (513) can detect the strength of the magnetic field of the OIS-x magnet (511) to detect the amount of movement or position of the OIS-x magnet (511). The amount of movement or position detected by the OIS-x sensor (513) can be used for x-axis direction shake correction feedback control. The OIS-y sensor (523) can detect the strength of the magnetic field of the OIS-y magnet (521) to detect the amount of movement or position of the OIS-y magnet (521). The amount of movement or position detected by the OIS-y sensor (523) can be used for y-axis direction shake correction feedback control.

[0272] Fig. 33 is a drawing for explaining the shake correction operation through yaw direction tilting correction of the camera device according to the present embodiment.

[0273] The moving part can be placed in the initial position without current being applied to the OIS-Yo coil (532). At this time, the moving part can include an image sensor (220). Furthermore, the moving part can include a moving plate (660), a sensor base (320), a frame (330), a housing (310), a carrier (340), an image sensor (220), and a lens.

[0274] When current is applied to the OIS-Yo coil (532), the moving part can be tilted in the yaw direction (see B in FIG. 33).

[0275] When current is applied to the OIS-yaw coil (532), the OIS-yaw magnet (531) can be tilted in the yaw direction due to the electromagnetic interaction between the OIS-yaw coil (532) and the OIS-yaw magnet (531). That is, it can be tilted around the first axis. In other words, it can be rotated within a limited range around the first axis (see A of FIG. 33). At this time, the image sensor (220) and the lens together with the OIS-yaw magnet (531) can be tilted in the yaw direction. More specifically, when a positive current is applied to the OIS-yaw coil (532), the OIS-yaw magnet (531), the image sensor (220), and the lens can move in one direction on the yaw. Additionally, when a reverse current is applied to the OIS-Yo coil (532), the OIS-Yo magnet (531), the image sensor (220), and the lens can move in the opposite direction of the yoke.

[0276] Meanwhile, the OIS-yaw sensor (533) can detect the strength of the magnetic field of the OIS-yaw magnet (531) to detect the amount of movement or position of the OIS-yaw magnet (531). The amount of movement or position detected by the OIS-yaw sensor (533) can be used for yaw direction shake compensation feedback control.

[0277] Fig. 34 is a drawing for explaining the shake correction operation through pitch direction tilting correction of the camera device according to the present embodiment.

[0278] The moving part can be placed in the initial position without current being applied to the OIS-pitch coil (542). At this time, the moving part can include an image sensor (220). Furthermore, the moving part can include a sensor base (320), a frame (330), a housing (310), a carrier (340), an image sensor (220), and a lens.

[0279] When current is applied to the OIS-pitch coil (542), the moving part can be tilted in the pitch direction (see D in Fig. 34).

[0280] When current is applied to the OIS-pitch coil (542), the OIS-pitch magnet (541) can be tilted in the pitch direction by the electromagnetic interaction between the OIS-pitch coil (542) and the OIS-pitch magnet (541). That is, it can be tilted around the second axis (see C of FIG. 34). In other words, it can be rotated within a limited range around the second axis. At this time, the image sensor (220) and the lens together with the OIS-pitch magnet (541) can be tilted in the pitch direction. More specifically, when a positive current is applied to the OIS-pitch coil (542), the OIS-pitch magnet (541), the image sensor (220), and the lens can move in one direction on the pitch. Additionally, when reverse current is applied to the OIS-pitch coil (542), the OIS-pitch magnet (541), the image sensor (220), and the lens can move in the other direction on the pitch.

[0281] Meanwhile, the OIS-pitch sensor (543) can detect the strength of the magnetic field of the OIS-pitch magnet (541) to detect the amount of movement or position of the OIS-pitch magnet (541). The amount of movement or position detected by the OIS-pitch sensor (543) can be used for pitch direction shake correction feedback control.

[0282] In this embodiment, the x-axis shift drive (see A in FIG. 10) and the y-axis shift drive (see B in FIG. 10) are such that the image sensor (220) is fixed and only the lens can move. However, the yaw tilting (see C in FIG. 10) and the pitch tilting (see D in FIG. 10) may be a module tilt method in which the lens and the image sensor (220) move together.
