Abstract
Description
Technical Field
[0001] The present disclosure relates to camera assemblies and electronic devices. Background Art
[0002] Electronic devices such as smartphones and tablet terminals are widely used in our daily lives. Nowadays, many electronic devices are equipped with camera components for capturing images. Some electronic devices are portable and therefore easy to carry. Therefore, users of electronic devices are able to easily take photos of objects using the camera components of the electronic devices anytime and anywhere.
[0003] Traditionally, when digital cameras are mounted on electronic devices such as smartphones, the long side of the image sensor is usually oriented vertically. On the other hand, the image sensor of a conventional digital camera is oriented horizontally. Conventional digital cameras have actuators and position detection functions in the longitudinal direction, resulting in the misalignment of the rotation center with the center of the optical axis.
[0004] This configuration is not optimal for electronic devices such as smartphones, which are composed of multiple cameras with optical image stabilization (OIS) mechanisms arranged in the longitudinal direction of the image sensor.
[0005] As described above, conventional camera assemblies and electronic devices cannot achieve an optimal layout for mounting multiple cameras with an OIS mechanism. Summary of the invention

[0011] a first actuator disposed at a position along a first axis orthogonal to the optical axis of the lens, and configured to apply a driving force to the movable substrate in a direction of the first axis so that the movable substrate on which the image sensor is disposed moves relative to the fixed plate;
[0012] a second actuator disposed at a position along the first axis and configured to apply a driving force to the movable substrate in a direction of the first axis so that the movable substrate moves relative to the fixed plate; and

[0026] The embodiments of the present disclosure will be described in detail, and examples of the embodiments will be illustrated in the accompanying drawings. Throughout the specification, the same or similar elements and elements having the same or similar functions are represented by similar reference numerals. The embodiments described herein with reference to the drawings are illustrative and intended to illustrate the present disclosure, but should not be construed as limiting the present disclosure.
[0027] Before explaining the features of the camera assembly and the electronic device according to the embodiments of the present disclosure, for better understanding, the schematic structure of the entire camera assembly and the entire electronic device is first explained.
[0028] Figure 1 is a plan view of a first side of an electronic device 10 according to an embodiment of the present disclosure, Figure 2 1 is a plan view of a second side of the electronic device 10 according to an embodiment of the present disclosure. The first side may be referred to as a back side of the electronic device 10, and the second side may be referred to as a front side of the electronic device 10.
[0029] like Figure 1 and Figure 2 As shown, the electronic device 10 may include: a display 20 , a camera assembly 30 including a pop-up lens unit 60 , and a battery cover 11 located on a first side of the electronic device 10 .
[0030] As an example, the electronic device 10 may be a mobile phone, a tablet computer, a personal digital assistant, or the like.
[0031] The camera assembly 30 has an imaging sensor that converts light that has passed through the color filter into an electrical signal. The signal value of the electrical signal depends on the amount of light that has passed through the color filter. The electronic device 10 may have one or more camera assemblies.
[0032] For example, Figure 1 As shown, the camera assembly 30 has a multi-camera function and may include a first camera assembly 30a and a second camera assembly 30b. The first camera assembly 30a and the second camera assembly 30b are connected via a spacer in the long side direction of the electronic device 10 (for example, Figure 4 The image sensors shown are arranged side by side in the direction of the long axis (Y axis) YL.
[0033] In addition, the camera assembly 30 is arranged in a housing provided in the electronic device 10 .
[0034] Figure 3 is a block diagram of an electronic device 10 according to this embodiment. Figure 3As shown, in addition to the display 20 and the camera assembly 30, the electronic device 10 may also include a main processor 40, an image signal processor 42, a memory 44, a power circuit 46, and a communication circuit 48. The display 20, the camera assembly 30, the main processor 40, the image signal processor 42, the memory 44, the power circuit 46, and the communication circuit 48 are interconnected via a bus 50.
[0035] The main processor 40 executes one or more program instructions stored in the memory 44. The main processor 40 implements various applications and data processing of the electronic device 10 by executing the program instructions. The main processor 40 can be one or more computer processors. The main processor 40 is not limited to one CPU core, but can have multiple CPU cores. The main processor 40 can be the main CPU of the electronic device 10, an image processing unit (IPU) or a DSP provided with a camera assembly 30.
[0036] The image signal processor 42 controls the camera assembly 30 and processes various image data captured by the camera assembly 30 to generate target image data. For example, the image signal processor 42 can apply de-mosaic processing, noise reduction processing, automatic exposure processing, automatic focus processing, automatic white balance processing, high dynamic range processing, etc. to the image data captured by the camera assembly 30.
[0037] In the present embodiment, the main processor 40 and the image signal processor 42 cooperate with each other to generate target image data of the object captured by the camera assembly 30. That is, the main processor 40 and the image signal processor 42 are used to capture the image of the object through the camera assembly 30 and apply various image processing to the captured image data.
[0038] The memory 44 stores program instructions to be executed by the main processor 40 and various data. For example, the data of the captured image is also stored in the memory 44.
[0039] The memory 44 may include a high-speed RAM memory and / or a non-volatile memory such as a flash memory and a disk memory. That is, the memory 44 may include a non-transitory computer-readable medium storing program instructions.
[0040] The power circuit 46 may include a battery, such as a lithium-ion rechargeable battery, and a battery management unit (BMU) for managing the battery.
[0041] The communication circuit 48 is used to receive and transmit data to communicate with a base station of a telecommunication network system, the Internet or other devices via wireless communication. The wireless communication may adopt any communication standard or protocol, including but not limited to GSM (Global System for Mobile communication), CDMA (Code Division Multiple Access), LTE (Long Term Evolution), LTE-Advanced, and 5G. The communication circuit 48 may include an antenna and an RF (Radio Frequency) circuit.
[0042] Next, we will refer to Figures 4 to 7 The description focuses on an example of the configuration of the camera assembly 30 of the electronic device 10 having the above-described configuration.
[0043] Figure 4 is a cross-sectional view showing a schematic configuration of a camera assembly of an electronic device according to an embodiment of the present disclosure. Figure 5A is focused on including Figure 4 A top view of the configuration of the image sensor of the camera assembly is shown. Figure 5B It is shown that the focus includes Figure 4 The illustrated cross-sectional view is an example of a configuration of an image sensor of a camera assembly taken along a first axis.
[0044] like Figure 4 , Figure 5A and Figure 5B As shown, the camera assembly 30 with an optical image stabilization (OIS) mechanism includes a lens barrel 1, a fixing plate 5, an image sensor 6, a sliding mechanism 8, a first actuator 71, a second actuator 72, a third actuator 73, a first position detection element 71b, a second position detection element 72b and a third position detection element 73b.
[0045] It should be noted that in Figure 4 In the embodiment, the structure for automatically focusing the camera assembly 30 is omitted. Figure 5A and Figure 5B In the Figure 4 The structure of the lens barrel 1 of the camera assembly 30 is shown.
[0046] like Figure 4 As shown, the lens barrel 1 is located above the image sensor 6. The lens barrel 1 includes a plurality of lenses 1a having an optical axis ZL.
[0047] The fixing plate 5 is fixed on the housing of the camera assembly 30 (that is, the camera assembly 30 is arranged on Figure 1The electronic device 10 shown is provided in a housing).
[0048] The movable base plate 4 is disposed above the fixed plate 5 and is movable relative to the fixed plate 5 in a direction perpendicular to the optical axis ZL of the lens 1 a .
[0049] The sliding mechanism 8 is provided between the fixed plate 5 and the movable substrate 4. The sliding mechanism 8 is used to allow the movable substrate 4 to slide on the fixed plate 5 in a direction perpendicular to the optical axis ZL.
[0050] For example, in Figure 4 In the example shown, the sliding mechanism 8 has a configuration that rolls on a sphere such as a bearing. However, alternatively, the sliding mechanism 8 may have a configuration that slides on a convex surface such as a spherical surface or a rib.
[0051] like Figure 4 , Figure 5A and Figure 5B As shown, the image sensor 6 is disposed on the movable substrate 4 for sensing light including an image of the subject 101 output from the lens 1 a of the lens barrel 1 .
[0052] In particular, if Figure 5A and Figure 5B As shown, the image sensor 6 is in a rectangular shape, which has a first side 61 and a second side 62 parallel to the first axis XL, and a third side 63 and a fourth side 64 parallel to the second axis YL. The rectangular shape is located on the upper surface of the movable substrate 4. The first side 61 and the second side 62 of the image sensor 6 are short sides of the rectangular shape. The third side 63 and the fourth side 64 of the image sensor 6 are long sides of the rectangular shape.
[0053] like Figure 5A and Figure 5B As shown, the first actuator 71 is arranged at a position along the first axis (X-axis) XL orthogonal to the optical axis ZL of the lens, and is used to apply a driving force to the movable substrate 6 in the direction of the first axis so that the movable substrate 4 on which the image sensor 6 is arranged moves relative to the fixed plate 5.
[0054] In particular, first actuator 71 is arranged adjacent to third face 63 of image sensor 6 .
[0055] More specifically, if Figure 5A and Figure 5B As shown, the first actuator 71 includes a first coil 71a, a first position detection element 71b and a first magnet 71c. The first coil 71a is arranged on the movable substrate 4. The first magnet 71c is a permanent magnet (e.g., a two-pole magnetized magnet) arranged on the fixed plate 5 to face the first coil 71a, and the first coil 71a and the first magnet 71c constitute a motor (magnetic conversion).
[0056] like Figure 5A and Figure 5B As shown, the second actuator 72 is arranged at a position along the first axis XL for applying a driving force to the movable substrate 4 in the direction of the first axis so that the movable substrate 4 moves relative to the fixed plate 5 .
[0057] More specifically, if Figure 5A and Figure 5B As shown, the second actuator 72 includes a second coil 72a, a second position detection element 72b and a second magnet 72c. The second coil 72a is arranged on the movable substrate 4. The second magnet 72c is a permanent magnet (e.g., a two-pole magnetized magnet) arranged on the fixed plate 5 to face the second coil 72a, and the second coil 72a and the second magnet 72c constitute a motor (magnetic conversion).
[0058] Therefore, if Figure 5A and Figure 5B As shown, the image sensor 6 is arranged between the first actuator 71 and the second actuator 72 on the first axis XL.
[0059] In this embodiment, if Figure 5A and Figure 5B As shown, the first actuator 71 and the second actuator 72 are symmetrically arranged around the optical axis ZL (arranged to be at the same distance from the optical axis ZL).
[0060] As described above, the first actuator 71 and the second actuator 72 are used to apply a driving force to the movable substrate 4 in the direction of the first axis XL so that the movable substrate 4 moves relative to the fixed plate 5 .
[0061] Specifically, the first actuator 71 and the second actuator 72 are used to apply a driving force to the movable substrate 4 so that the movable substrate 4 on which the image sensor 6 is arranged rolls on the fixed plate around the optical axis ZL.
[0062] like Figure 5A and Figure 5B As shown, the third actuator 73 is arranged at a position along the first axis XL, and is used to apply a driving force to the movable substrate 4 in the second axis (Y axis) YL direction perpendicular to the optical axis ZL and the first axis XL, so that the movable substrate 4 moves relative to the fixed plate 5.
[0063] In particular, the third actuator 73 is arranged such that the second actuator 72 is located between the fourth sides 64 of the image sensor 6 .
[0064] More specifically, if Figure 5A and Figure 5BAs shown, the third actuator 73 includes a third coil 73a and a third magnet 73c. The third coil 73a is arranged on the movable substrate 4. The third magnet 73c is a permanent magnet (e.g., a two-pole magnetized magnet) arranged on the fixed plate 5 to face the third coil 73a, and the third coil 73a and the third magnet 73c constitute a motor (magnetic conversion).
[0065] like Figure 5A and Figure 5B As shown, the first position detecting element 71 b is arranged on the movable substrate 4 to be adjacent to the first actuator 71 for detecting the relative position of the first position detecting element 71 a with respect to the fixed plate 5 .
[0066] Specifically, the first position detecting element 71 b detects the relative position of the first position detecting element 71 b with respect to the fixing plate 5 in the direction of the second axis YL.
[0067] For example, the first position detecting element 71b is arranged on the movable substrate 4 to be located at the center of the first coil 71a. The first position detecting element 71b is a first Hall element 71b for detecting the magnetism of the first magnet 71c.
[0068] In this case, the first position detecting element 71 b detects the relative position with respect to the fixed plate 5 by detecting the magnetism (magnetism of the S pole and the N pole) of the first magnet 71 c .
[0069] like Figure 5A and Figure 5B As shown, the second position detecting element 72 b is arranged on the movable base plate 4 to be adjacent to the second actuator 72 for detecting the relative position of the second position detecting element 72 with respect to the fixed plate 5 .
[0070] Specifically, the second position detecting element 72 b detects the relative position of the second position detecting element 72 b with respect to the fixing plate 5 in the direction of the second axis YL.
[0071] For example, the second position detecting element 72b is arranged on the movable substrate 4 so as to be located at the center of the second coil 72a. The second position detecting element 72b is a second Hall element 72b for detecting the magnetism of the second magnet 72c.
[0072] In this case, the second position detecting element 72 b detects the relative position with respect to the fixed plate 5 by detecting the magnetism (magnetism of the S pole and the N pole) of the second magnet 72 c .
[0073] like Figure 5A and Figure 5B As shown, the third position detecting element 73 b is arranged on the movable base plate 4 to be adjacent to the third actuator 73 , for detecting the relative position of the third position detecting element 73 b with respect to the fixed plate 5 .
[0074] Specifically, the third position detecting element 73 b detects the relative position of the second position detecting element 72 b with respect to the fixing plate 5 in the direction of the first axis XL.
[0075] For example, the third position detecting element 73b is arranged on the movable substrate 4 to be located at the center of the third coil 73a. The third position detecting element 73b is a third Hall element 73b for detecting the magnetism of the third magnet 73c.
[0076] In this case, the third position detecting element 73 b detects the relative position with respect to the fixed plate 5 by detecting the magnetism (magnetism of the S pole and the N pole) of the third magnet 73 c .
[0077] Further, for example, Figure 5A As shown, the first position detecting element 71a, the second position detecting element 72a, and the third position detecting element 73a are arranged at positions along the first axis XL.
[0078] Further, for example, Figure 5A and 5B As shown, the first position detecting element 71a and the second position detecting element 72a are symmetrically arranged around the optical axis ZL (arranged to be at the same distance from the optical axis ZL).
[0079] For example, the relative position of the image sensor 6 relative to the fixed plate 5 in the direction of the second axis YL, or the relative position of the image sensor relative to the fixed plate 5 when rolling around the optical axis, is obtained based on the position detected by the first position detection element 71b and the position detected by the second position detection element 72b.
[0080] In more detail, when the polarity of the position detected by the first position detecting element 71b in the second axis YL direction is the same as the polarity of the position detected by the second position detecting element 72b in the second axis YL direction, the image sensor 6 is displaced in the X-axis XL direction.
[0081] On the other hand, when the polarity of the position detected by the first position detecting element 71 b in the second axis YL direction is different from the polarity of the position detected by the second position detecting element 72 b in the second axis YL direction, the image sensor 6 rolls around the optical axis ZL.
[0082] Furthermore, the relative position of the image sensor 6 with respect to the fixing plate 5 in the direction of the first axis XL is obtained based on the position detected by the third position detecting element 73 b .
[0083] By arranging the first to third position detection elements 71b, 72b, and 73b such as the Hall element (detection using the NS pole boundary) described above, the rolling center of the image sensor 6 is located at the center of the optical axis ZL, and the first position detection element 71b and the second position detection element 72b are located on the first axis XL. Therefore, while reducing the rolling and interference in the direction of the first axis XL, there is no misalignment in the direction of the second axis YL.
[0084] Here, it should be noted that other camera assemblies (not shown) can be arranged adjacent to the camera assembly 30 in the direction of the second axis YL.
[0085] This situation corresponds to, for example, a situation where the first camera assembly 30a and the second camera assembly 30b are arranged side by side in the long side direction of the electronic device 10 via a spacer, such as Figure 1 shown.
[0086] As described above, the OIS mechanism such as the actuator and the position sensing element is located in the horizontal direction of the camera assembly (the first axis direction XL), thereby being able to shorten the vertical direction of the camera assembly (the second axis direction YL).
[0087] For this reason, there are no OIS mechanisms such as actuators or position detection elements between adjacent camera components, which increases placement freedom for other applications.
[0088] Therefore, since the camera assembly 30 has the above-mentioned configuration, the camera assembly 30 can achieve an optimal layout for mounting a plurality of cameras having an OIS mechanism.
[0089] Here, an example of the operation of the camera assembly 30 having the above-described configuration will be described.
[0090] Figure 6 is focused on Figure 5A A top view of the image sensor and first to third actuators of the camera assembly is shown. Figure 7 It is shown Figure 6 A top view of an example of a state in which an image sensor of a camera assembly is rolled about an optical axis is shown.
[0091] As described above, the camera assembly 30 has an OIS mechanism.
[0092] That is, the first actuator 71 , the second actuator 72 , and the third actuator 73 perform OIS control on the image sensor 6 together with the first position detecting element 71 a , the second position detecting element 72 a , and the third position detecting element 73 a .
[0093] like Figure 6As shown, the first actuator 71 and the second actuator 72 apply a driving force to the movable substrate 4 in the first axis XL direction so that the movable substrate 4 moves relative to the fixed plate 5. In addition, the third actuator 73 applies a driving force to the movable substrate 4 in the second axis YL direction so that the movable substrate 4 moves relative to the fixed plate 5.
[0094] In particular, if Figure 7 As shown, the first actuator 71 and the second actuator 72 apply a driving force to the movable substrate 4 so that the movable substrate 4 on which the image sensor 6 is arranged rolls on the fixed plate around the optical axis ZL.
[0095] As described above, the relative position of the image sensor 6 relative to the fixed plate 5 in the direction of the second axis YL, or the relative position of the image sensor relative to the fixed plate 5 when rolling around the optical axis, is obtained based on the position detected by the first position detection element 71b and the position detected by the second position detection element 72b.
[0096] In more detail, when the polarity of the position detected by the first position detecting element 71b in the second axis YL direction is the same as the polarity of the position detected by the second position detecting element 72b in the second axis YL direction, the image sensor 6 is displaced in the X-axis XL direction.
[0097] On the other hand, when the polarity of the position detected by the first position detecting element 71 b in the second axis YL direction is different from the polarity of the position detected by the second position detecting element 72 b in the second axis YL direction, the image sensor 6 rolls around the optical axis ZL.
[0098] Furthermore, the relative position of the image sensor 6 with respect to the fixing plate 5 in the direction of the first axis XL is obtained based on the position detected by the third position detecting element 73 b .
[0099] As described above, by arranging the first to third position detection elements 71b, 72b, and 73b such as the Hall element (detection using the NS pole boundary), the rolling center of the image sensor 6 is located at the center of the optical axis ZL, and the first position detection element 71b and the second position detection element 72b are located on the first axis XL. Therefore, while reducing the rolling and interference in the direction of the first axis XL, there is no misalignment in the direction of the second axis YL.
[0100] here, Figure 8 is a top view showing a configuration focusing on an image sensor and first to third actuators of a camera assembly according to a first modified example. Fig. 9 It is shown Figure 8 A top view of an example of a state in which an image sensor of a camera assembly is rolled about an optical axis is shown.
[0101] For example, Figure 8 and Fig. 9 As shown, the camera assembly 30 may further include a fourth actuator 74 along the first axis. The fourth actuator 74 applies a driving force to the movable substrate in the direction of the second axis, so that the movable substrate 4 moves relative to the fixed plate 5.
[0102] like Figure 8 As shown, the fourth actuator 74 includes a fourth coil 74a and a fourth magnet 74c. The fourth coil 74a is arranged on the movable substrate 4. The fourth magnet 74c is a permanent magnet (e.g., a two-pole magnetized magnet) arranged on the fixed plate 5 to face the fourth coil 74a, and the third coil 73a and the second magnet 73c constitute a motor (magnetic conversion).
[0103] The fourth position detecting element 74b is arranged on the movable substrate 4 to be located at the center of the fourth coil 74a. The fourth position detecting element 74b is a fourth Hall element 74b for detecting the magnetism of the fourth magnet 74c.
[0104] The fourth position detecting element 74 b detects the relative position with respect to the fixing plate 5 by detecting the magnetism (magnetism of the S pole and the N pole) of the fourth magnet 74 c .
[0105] The first actuator 71 , the second actuator 72 , the third actuator 73 , and the fourth actuator 74 perform OIS control on the image sensor together with the first position detecting element 71 a , the second position detecting element 72 a , the third position detecting element 73 a , and the fourth position detecting element 74 a .
[0106] The third actuator 73 and the fourth actuator 74 are arranged symmetrically around the optical axis ZL (arranged to be at the same distance from the optical axis ZL).
[0107] The camera assembly according to the first improvement can improve the driving force and position detection accuracy of the OIS control in the direction of the first axis XL.
[0108] Other structures and Figure 4 , Figure 5A and Figure 5B The camera components shown are identical.
[0109] As described above, the camera assembly 30 of the electronic device 10 according to the present embodiment includes: a fixed plate 5 fixed on the housing of the camera assembly 30; a movable substrate 4 arranged above the fixed plate 5 and movable relative to the fixed plate 5 in a direction perpendicular to the optical axis ZL of the lens 1a; an image sensor 6 arranged on the movable substrate 4 for sensing light output from the lens 1a; a first actuator 71 arranged at a position along a first axis XL orthogonal to the optical axis ZL of the lens 1a, for applying a driving force to the movable substrate 4 in the direction of the first axis XL so that the movable substrate 4 on which the image sensor 6 is arranged moves relative to the fixed plate 5; a second actuator 72 arranged at a position along the first axis XL, for applying a driving force to the movable substrate 4 in the direction of the first axis XL so that the movable substrate 4 moves relative to the fixed plate 5; and a third actuator 73 arranged at a position along the first axis XL, for applying a driving force to the movable substrate 4 in the direction of the second axis YL perpendicular to the optical axis ZL and the first axis XL so that the movable substrate 4 moves relative to the fixed plate 5. Here, the image sensor 6 is arranged between the first actuator 71 and the second actuator 72 on the first axis XL.
[0110] Therefore, the OIS mechanism such as the actuator and the position sensing element is located in the horizontal direction of the camera assembly (the first axis direction XL), so that the vertical direction of the camera assembly (the second axis direction YL) can be shortened.
[0111] For example, there are no OIS mechanisms such as actuators or position detection elements between adjacent camera components, which increases placement freedom for other applications.
[0112] As described above, the camera module and the electronic device according to the embodiments of the present disclosure can achieve an optimal layout for mounting a plurality of cameras with an OIS mechanism.
