This application is based on and claims priority under 35 U.S.C. 119 to Korean Patent Application No. 10-2020-0015830, filed on Feb. 10, 2020, in the Korean Intellectual Property Office, the disclosure of which is herein incorporated by reference in its entirety.
Various embodiments relate to an electronic device including a camera assembly, and, more particularly, to automatic physical reconfigurations of the camera assembly during falls to prevent damage.
Recently, electronic devices including cameras (for example, digital cameras, digital camcorders, or smartphones) have become increasingly widespread. An electronic device including a camera may provide an imaging function. For example, the electronic device may output, through a display, preview images acquired from the camera, and may capture and store an image according to an input from a user.
Meanwhile, a camera may include a transparent window covering the camera, and a camera lens mounted such that the interval between the lens and the window (e.g., an air gap) is small relative to the size of a transparent area of the window (e.g., a 0.1 mm gap), which serves as a pathway for incident light (e.g., a printed hole), and the size of a structure supporting the window (e.g., a camera deco).
The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.
In line with the increasing demand for high-performance cameras, image sensors and lenses included in cameras have generally increased in size. Nowadays, smartphones may be equipped with camera modules housing one or more cameras, which protrudes from a surface of the smartphone. If an electronic device employing a large and heavy lens falls, the camera lens and the window may collide. Factors tending to increase the likelihood of collision include the physical protrusion of the lens which, as noted above, has increased in comparison with older, single module cameras. A collision between the camera lens and the window may damage the upper surface of the lens, and foreign or broken components may be scattered within the assembly, affecting the ability to capture images or degrading the quality of any captured images.
Various embodiments may provide a camera assembly and an electronic device including the same, the camera assembly having such a structure that, when the electronic device falls, no collision occurs between the camera lens and the window.
An electronic device according to certain embodiments may include a housing including a first surface facing a first direction, a second surface facing a second direction opposite to the first direction, and a side surface at least partially surrounding a space formed between the first surface and the second surface, a camera module seated inside the housing and disposed at a position aligned with an opening formed in the first surface, a housing member including a first portion connected to the first surface at a position where the opening is formed and forming a hollow corresponding to the opening, a second portion extending from the first portion in a direction substantially identical to the first direction and surrounding the hollow, and a window seated on the second portion covering the hollow, a camera module seated within the housing, and aligned with an opening formed in the first surface, a processor operatively connected to the camera module; and a memory operatively connected to the processor, wherein the camera module includes at least one lens, and a lens barrel including a cylindrical lower portion having a diameter greater than the at least one lens, an extension portion extending from a top surface of the lower portion in a direction oblique to the first direction, and a cylindrical upper portion extending from a top surface of the extension portion in the first direction and having a diameter smaller than the lower portion, and wherein a distance from the top surface of the lower portion to a bottom surface of the first portion is smaller than a distance from a top surface of the upper portion to a bottom surface of the window.
In addition, a camera assembly according to certain embodiments may include a housing member including a first portion forming a hollow, a second portion extending from the first portion in a first direction and surrounding the hollow, and a window seated on the second portion covering the hollow, a frame spaced by a predetermined distance apart from a bottom surface of the first portion in a second direction opposite to the first direction, a lens barrel aligned with the hollow and seated within the frame; and at least one lens disposed within in the lens barrel, wherein the lens barrel comprises a cylindrical lower portion having a diameter greater than the at least one lens, an extension portion extending from a top surface of the lower portion in a direction oblique to the first direction, a cylindrical upper portion extending from a top surface of the extension portion in the first direction and having a diameter smaller than the lower portion, and wherein a distance from the top surface of the lower portion to the bottom surface of the first portion is smaller than a distance from a top surface of the upper portion to a bottom surface of the window.
In addition, an electronic device according to certain embodiments may include at least one actuator disposed within the frame and configured to change a position of the at least one lens, a driver integrated circuit (IC) disposed within the frame and configured to drive the at least one actuator, a sensor module disposed within the frame and configured to detect motion of the camera assembly, and a processor operatively connected to the sensor module and the driver IC, wherein the processor is configured to detect the motion of the camera assembly from the sensor module as sensor information, determine, based on the sensor information, whether the camera assembly is falling, and when it is determined that the camera assembly is falling, drive the at least one actuator through the driver IC to change the position of the at least one lens.
According to certain embodiments, when the electronic device falls, the lens barrel and the structure for supporting the window may collide first, and this structure may prevent the camera lens and the window from colliding with each other.
Besides, various advantageous effects directly or indirectly inferable from this document may be provided.

The AF actuator 312 may move the at least one lens to the center point in a Z-axis direction. Herein, the Z-axis direction may be the direction of a center axis of the lens assembly 311, i.e., the direction of the center axis of a lens barrel on which at least one lens is seated. For example, the AF actuator 312 may move the position of the at least one lens in the downward/upward direction. According to an embodiment, the AF actuator 312 may include a voice coil motor.
The AF driver 313 may control the driving of the AF actuator 312. For example, the AF driver 313 may control a driving current applied to the AF actuator 312. According to an embodiment, the AF driver 313 may be provided in the form of an integrated circuit (IC).
In response to the motion of the camera assembly or the electronic device including the same, the image stabilizer actuator may move at least one lens, included in the lens assembly 311, or the image sensor in a specific direction, or may control the operation characteristics of the image sensor (e.g., may adjust read-out timing). This may at least partially compensate for a negative effect of the motion (e.g., hand shake) on a captured image. According to an embodiment, the image stabilizer actuator may move the at least one lens to the center point in an X-axis direction and/or Y-axis direction. Herein, the X-axis direction and the Y-axis direction are directions perpendicular to the Z-axis direction, and may be directions toward the center axis of the lens assembly 311, that is, directions toward the center axis of a lens barrel on which at least one lens is seated. For example, the image stabilizer actuator may move the at least one lens in the leftward/rightward direction. According to an embodiment, the image stabilizer actuator may include a voice coil motor. According to an embodiment, the image stabilizer actuator may sense the motion of the camera assembly and the electronic device by using a sensor module 340 (e.g., a gyro sensor or an acceleration sensor) disposed inside or outside of the camera assembly. According to an embodiment, the image stabilizer actuator may be implemented as, for example, an optical image stabilizer (OIS) actuator.
The image stabilizer driver may control the driving of the image stabilizer actuator. For example, the image stabilizer driver may control a driving current applied to the image stabilizer actuator. According to an embodiment, the image stabilizer driver may be provided in the form of an integrated circuit.
The buffer memory may at least temporarily store at least a part of an image, acquired through the image sensor, for the next image processing operation. For example, when image acquisition according to a shutter is delayed or multiple images are acquired at high speed, an acquired original image (e.g., a Bayer-patterned image or a high-quality image) may be stored in the buffer memory, and a copied image (e.g., a low-quality image) corresponding thereto may be displayed (or previewed) through the display. Thereafter, if a designated condition is satisfied (e.g., a user input or system command), at least a part of the original image stored in the buffer memory may be acquired and processed by, for example, an image signal processor. According to an embodiment, the buffer memory may be formed as a part of the memory 330 or as a separate memory which is independently operated.
The image signal processor may perform one or more types of image processing with respect to the image acquired through the image sensor or the image stored in the buffer memory. The one or more types of image processing may include, for example, depth map generation, three-dimensional modeling, panorama generation, feature point 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 may control at least one (e.g., the image sensor) of the elements included in the camera module 310 (e.g., may control exposure time or read-out timing). The image processed by the image signal processor may be stored in the buffer memory again in order to be additionally processed, or may be provided to an element outside the camera module 310 (e.g., the memory 330, the display, the external electronic device (e.g., the electronic device 102 and 104 or the server 108 in
The processor 320 may control at least one other element of the camera assembly or the electronic device, and may process or calculate various data. The processor 320 may execute commands stored in the memory 330.
According to an embodiment, the processor 320 may acquire sensor information from the sensor module 340. The sensor information may include, for example, a sensor value according to the motion of the camera assembly or the electronic device. The sensor value may include, for example, acceleration values of the camera assembly or the electronic device in the X-axis, Y-axis, and Z-axis directions. In this case, the processor 320 may determine, based on the sensor information, whether the camera assembly or the electronic device is falling. For example, when the time, during which the acceleration in the Z-axis direction maintains a value equal to or greater than a designated value, exceeds a designated time, the processor 320 may determine that the camera assembly or the electronic device is falling.
According to an embodiment, when it is determined that the camera assembly or the electronic device is falling, the processor 320 may adjust the position of at least one lens included in the lens assembly 311. For example, the processor 320 may adjust the position of the at least one lens by using at least one of the AF actuator 312 or the image stabilizer actuator. In one example, the processor 320 may move, using the AF actuator 312, the position of the at least one lens in the upward/downward direction, thereby fixing the position of the at least one lens to the center point in the Z-axis direction (e.g., code 250 when the full range is code 512). In another example, the processor 320 may move, using the image stabilizer actuator, the position of the at least one lens in the leftward/rightward direction, thereby fixing the position of the at least one lens to the center point in the X-axis direction and/or the Y-axis direction (e.g., a point at which the X-axis (or Y-axis) crosses the center axis of the lens barrel). In another example, the processor 320 may move, using the AF actuator 312 and the image stabilizer actuator, the position of the at least one lens in the upward, downward, leftward, and rightward directions, thereby fixing the position of the at least one lens to the center point in the X-axis direction, the Y-axis direction, and the Z-axis direction.
The memory 330 may store various data used by at least one element of the camera assembly or the electronic device. According to an embodiment, the memory 330 may store data and commands related to controlling the camera module 310, the sensor module 340, the memory 330, and the display.
The sensor module 340 may generate an electrical signal or a data value (sensor value) corresponding to the state of motion of the camera assembly or the electronic device. According to an embodiment, the sensor module 340 may include at least one of a gyro sensor or an acceleration sensor.
The display may display various types of contents (e.g., a text, an image, a video, an icon, or a symbol) to a user. The display may include a touchscreen, and may receive touch, gesture, proximity, or hovering input using, for example, an electronic pen or a portion of the user's body.
According to an embodiment, the camera assembly or the electronic device may include multiple camera modules 310 having different properties or functions. In this case, for example, at least one of the multiple camera modules 310 may be a wide-angle camera, and at least one other camera thereof may be a telephoto camera. Similarly, at least one of the multiple camera modules 310 may be a front camera, and at least one other camera may be a rear camera.
Referring to
The electronic device may include a housing including a first surface (e.g., a front surface) facing a first direction (e.g., a front direction, (+) Z-axis direction), a second surface (e.g., a rear surface) facing a second direction (e.g., a front direction, (−) Z-axis direction) opposite to the first direction, and a side surface at least partially surrounding the space formed between the first surface and the second surface. The camera module 400 may be seated inside the housing, and may be disposed at a position aligned with an opening formed in the first surface. Further, the decorative member 410 may include a first frame 411 connected to the first surface at a position at which the opening is formed, and including a hollow corresponding to the opening, a second frame 413 extending from the first frame 411 in a direction substantially identical to the first direction and surrounding the hollow, and a window (or a window layer) 420 seated in the second frame 413 so as to cover the hollow. According to an embodiment, the first frame 411 and the second frame 413 may be integrated with each other. In this case, the first frame 411 may be a first portion of the decorative member 410, and the second frame 413 may be a second portion of the decorative member 410.
The camera module 400 may include at least one lens (or a lens part) (reference numeral 450 in
The lens barrel 440 may include a cylindrical lower portion 441 having a larger diameter than the at least one lens, an extension portion 442 extending from the top surface 441a of the lower portion 441 in a direction oblique to the first direction, and a cylindrical upper portion 443 extending from the top surface of the extension portion 442 in the first direction and having a smaller diameter than the lower portion 441. The upper portion 443 may be disposed to be spaced a predetermined distance apart from the window 420. According to an embodiment, the camera module 400 and the decorative member 410 may be mounted such that the distance (d1) 403 between the top surface 443a of the upper portion 443 and the bottom surface 420a of the window 420 is equal to or less than a designated distance (e.g., about 0.1 mm), in consideration of the size of the transparent region (e.g., a printed hole) of the window 420, which serves as an incident path of light, and the size of a structure (e.g., the first frame 411 and the second frame 413) for supporting the window 420.
According to an embodiment, the electronic device may have a structure in which the lens barrel 440 first collides with the decorative member 410 for supporting the window 420 so as to prevent the lens barrel 440, in which the at least one lens has been seated, from colliding with the window 420 when the electronic device falls. This structure may include, for example, a structure in which left and right top ends 402 of the lower portion 441, which correspond to shoulder portions of the lens barrel 440, first collide with the first frame 411 positioned at the lower end of the decorative member 410 when the electronic device falls.
In order for the left and right top ends 402 of the lower portion 441 to first collide with the first frame 411, the distance between left and right top ends 402 of the lower portion 441 and the first frame 411 may be set smaller than the distance between the upper portion 443 of the lens barrel 440 and the window 420. That is, the distance (d2) 404 from the top surface 441a of the lower portion 441 to the bottom surface 411a of the first frame 411 may be set smaller than the distance (d1) 403 from the top surface 443a of the upper portion 443 to the bottom surface 420a of the window 420. Further, when seen from above the window 420, the left and right top ends 402 of the lower portion 441 may at least partially overlap with the first frame 411. That is, the distance (d4) 406 from the center axis 401 of the lens barrel 440 to the side surface of the lower portion 441 may be set larger than the distance (d3) 405 from the center axis 401 of the lens barrel 440 to the bottom surface 411a of the first frame 411.
According to an embodiment, the camera module 400 may further include a third frame 430 which surrounds and seats at least a part of the lens barrel 440. For example, a hollow may be formed in the third frame 430, and the lower portion 441 of the lens barrel 440 may be inserted and seated in the hollow.
According to an embodiment, the electronic device may further include a protective member (or a damping member) 510 disposed at a position at which the left and right top ends 402 of the lower portion 441 of the lens barrel 440 risk collision with the first frame 411 of the decorative member 410. The protective member 510 may reduce the level of shock generated when the left and right top ends 402 of lower portion 441 of the lens barrel 440 collide with the first frame 411 of the decorative member 410. Further, the protective member 510 may prevent foreign matter from entry into the camera module from the side surface of the camera module.
According to an embodiment, the protective member 510 may be formed using, or include at least one of a poron or a rubber.
According to an embodiment, the protective member 510 may be disposed between the top surface 431 of the third frame 430, which surrounds the lower portion 441 of the lens barrel 440 in a lateral direction at the left and right top ends 402 of the lower portion 441 of the lens barrel 440 and the bottom surface 411a of the first frame 411 of the decorative member 410. According to another embodiment, the protective member 510 may be disposed between the top surface 441a of the lower portion 441 of the lens barrel 440 and the bottom surface 411a of the first frame 411 of the decorative member 410. According to another embodiment, the protective member 510 may be disposed between the top surface 431 of the third frame 430 and the bottom surface 411a of the first frame 411 of the decorative member 410 in a lateral direction at the left and right top ends 402 of the lower portion 441 of the lens barrel 440 and between the top surface 441a of the lower portion 441 of the lens barrel 440 and the bottom surface 411a of the first frame 411 of the decorative member 410.
The compression ratio of the protective member 510 in the first direction may be equal to or smaller than a designated value. For example, when the compression ratio in the first direction reaches a threshold, the strain of the protective member 510 may rapidly increase, and thus the protective member 510 may not be compressed. According to an embodiment, a value obtained by multiplying the thickness of the protective member 510 in the first direction and the compression ratio may be smaller than the distance 403 between the top surface 443a of the upper portion 443 of the lens barrel 440 and the bottom surface 420a of the window 420. In one example, if the distance 403 between the top surface 443a of the upper portion 443 of the lens barrel 440 and the bottom surface 420a of the window 420 is 0.1 mm and the compression ratio of the protective member 510 in the first direction is 0.3 (30%), it is desirable that the thickness of the protective member 510 in the first direction be about 0.3 mm (0.3 mm*0.3=0.09 mm<0.1 mm). That is, the protective member 510 may be provided so as to maintain the minimum gap between the top surface 443a of the upper portion 443 of the lens barrel 440 and the bottom surface 420a of the window 420 with reference to the maximum compression amount.
The camera module 400 may be connected to a processor (e.g., the processor 120 in
In the above description, the camera module 400 and the decorative member 410 have been described as elements which are disposed in the housing of the electronic device or are connected to a portion of the housing. However, the camera module 400 and the decorative member 410 may be formed as independent elements constituting a camera assembly.
According to an embodiment, the camera assembly may include a first frame 411 which includes a hollow, a second frame 413 which extends from the first frame 411 in a first direction (e.g., a front direction, (+) Z-axis direction) and surrounds the hollow, a third frame 430 which is disposed in a second direction (e.g., a rear direction, (−) Z-axis direction) opposite to the first direction while being spaced a predetermined distance apart from a bottom surface 411a of the first frame 411, a lens barrel 440 which is disposed at a position aligned with the hollow and is seated inside the third frame 430, a window 420 which is seated in the second frame 413 so as to cover the hollow, and at least one lens (reference numeral 450 in
The lens barrel 440 of the camera assembly may include elements identical or similar to those of the lens barrel 440 of the electronic device. For example, the lens barrel 440 of the camera assembly may include a cylindrical lower portion 441 having a diameter larger than the at least one lens, an extension portion 442 extending from the top surface 441a of the lower portion 441 in a direction oblique to the first direction, and a cylindrical upper portion 443 extending from the top surface of the extension portion 442 in the first direction and having a smaller diameter than the lower portion 441.
Further, in the camera assembly, when the camera assembly falls, left and right top ends 402 of the lower portion 441 of the lens barrel 440 may first collide with the first frame 411 so as to prevent the lens barrel 440, in which the at least one lens has been seated, from colliding with the window 420. To this end, the distance (d2) 404 from the top surface 441a of the lower portion 441 to the bottom surface 411a of the first frame 411 may be set smaller than the distance (d1) 403 from the top surface 443a of the upper portion 443 to the bottom surface 420a of the window 420. Further, the distance (d4) 406 from the center axis 401 of the lens barrel 440 to the side surface of the lower portion 441 may be set larger than the distance (d3) 405 from the center axis 401 of the lens barrel 440 to the bottom surface 411a of the first frame 411.
According to an embodiment, the camera assembly may further include a protective member 510 which is disposed at a position at which the left and right top ends 402 of the lower portion 441 of the lens barrel 440 are at risk of colliding with the first frame 411. The protective member 510 may reduce the level of shock generated when the left and right top ends 402 of lower portion 441 of the lens barrel 440 collide with the first frame 411.
According to an embodiment, the protective member 510 may be disposed between the top surface 431 of the third frame 430 and the bottom surface 411a of the first frame 411 in a lateral direction at the left and right top ends 402 of the lower portion 441 of the lens barrel 440. According to another embodiment, the protective member 510 may be disposed between the top surface 441a of the lower portion 441 of the lens barrel 440 and the bottom surface 411a of the first frame 411. According to another embodiment, the protective member 510 may be disposed between the top surface 431 of the third frame 430 and the bottom surface 411a of the first frame 411 in a lateral direction at the left and right top ends 402 of the lower portion 441 of the lens barrel 440 and between the top surface 441a of the lower portion 441 of the lens barrel 440 and the bottom surface 411a of the first frame 411.
According to an embodiment, the camera assembly may include a processor (e.g., the processor 120 in
According to an embodiment, at least one actuator (e.g., the AF actuator 312 or the OIS actuator), capable of changing the position of at least one lens included in the lens barrel 440, and a driver (e.g., the AF driver 313 or the OIS driver), configured to drive the at least one actuator, may be further disposed inside the third frame 430.
Referring to
The lens barrel 440 may include a cylindrical lower portion 441 having a diameter larger than the at least one lens 450, an extension portion 442 extending from the top surface of the lower portion 441 in a direction oblique to the first direction (e.g., (+) Z-axis direction), and a cylindrical upper portion 443 extending from the top surface of the extension portion 442 in the first direction and having a diameter smaller than the lower portion 441.
The frame 430 may form at least a portion of a housing of the camera module 400. The frame 430 may seat the lens barrel 440 while surrounding at least a portion of the lens barrel 440. For example, a hollow may be formed in the frame 430, and the lower portion 441 of the lens barrel 440 may be inserted and seated in the hollow.
A movement restriction member 460 (e.g., a stopper) may be disposed within the frame 430. The movement restriction member 460 may restrict the movement of the lens barrel 440 when the lens barrel 440 moves according to a change in position (e.g., movement) of the at least one lens 450. For example, when the lens barrel 440 moves in the first direction (e.g., (+) Z-axis direction), if the lens barrel 440 moves a predetermined distance or further, the movement restriction member 460 may come into contact with the frame 430, restricting the movement of the lens barrel 440. At least one actuator capable of adjusting (or changing) the position of the at least one lens 450, and a driver 630 configured to drive the at least one actuator may be further disposed within the frame 430. The actuator may include a magnetic material 610 and a voice coil 620.
In order to perform autofocusing of the camera module, the actuator may include at least one of an AF actuator (e.g., the AF actuator 312) configured to adjust the position of the at least one lens 450 and an OIS actuator configured to adjust the position of the at least one lens 450 in response to the motion of the camera module.
According to an embodiment, the actuator may adjust the position of the at least one lens 450 according to control of a processor (e.g., the processor 120 in
According to an embodiment, when the camera assembly or the electronic device falls, if the position of the at least one lens 450 is moved toward the center of the lens barrel 440, the at least one lens 450 may be prevented from colliding with the inner surface of the lens barrel 440 when the left and right top ends 402 of the lower portion 441, which correspond to shoulder portions of the lens barrel 440, collide with the first frame 411 positioned at the lower end of the decorative member 410. For example, when the at least one lens 450 is positioned away from the center point in the lens barrel 440 and close to the inner surface of the lens barrel 440 in order to perform auto-focusing and prevent hand shake, the at least one lens 450 may collide with the inner surface of the lens barrel 440 by a shock according to the falling. Therefore, the at least one lens 450 may be prevented from colliding with the inner surface of the lens barrel 440 by moving the position of the at least one lens 450 toward the center of the lens barrel 440 to control the at least one lens 450 to be maximally far away from the inner surface of the lens barrel 440. Further, when the camera assembly or the electronic device falls, moving the position of the at least one lens 450 toward the center of the lens barrel 440 can maximally reduce the gap (e.g., air gap) between the at least one lens 450 or the lens barrel 440 and the decorative member 410 at the time of designing the inner structure of the camera assembly or the electronic device.

According to certain embodiments, the at least one actuator may include a first actuator (e.g., the auto focus actuator 312) configured to adjust the position of the at least one lens in order to perform auto-focusing of the camera module, and a second actuator (e.g., OIS actuator) configured to adjust the position of the at least one lens in response to the motion of the camera module, and when it is determined that the electronic device is falling, the processor may drive the first actuator to move the position of the at least one lens in the direction of the center axis of the lens barrel, and drive the second actuator to move the position of the at least one lens in a direction perpendicular to the center axis of the lens barrel, thereby moving the at least one lens toward the center of the lens barrel.
As described above, according to certain embodiments, a camera assembly may include a decorative member (e.g., the decorative member 410), which includes a first portion (e.g., the first frame 411) including a hollow, a second portion (e.g., the second frame 413) extending from the first portion in a first direction and surrounding the hollow, and a window (e.g., the window 420) seated on the second portion so as to cover the hollow, a frame (e.g., the third frame 430), which is disposed to be spaced a predetermined distance apart from the bottom surface (e.g., the bottom surface 411a) of the first portion in a second direction opposite to the first direction, a lens barrel (e.g., the lens barrel 440), which is disposed at a position aligned with the hollow and is seated inside the frame, and at least one lens (e.g., the lens 450), which is disposed inside in the lens barrel, such that the lens barrel includes a cylindrical lower portion (e.g., the lower portion 441) having a larger diameter than the at least one lens, an extension portion (e.g., the extension portion 442) extending from the top surface (e.g., the top surface 441a) of the lower portion in a direction oblique to the first direction, and a cylindrical upper portion (e.g., the upper portion 443) extending from the top surface of the extension portion in the first direction and having a smaller diameter than the lower portion.

Referring to
In operation 730, the processor may determine, based the sensor information, whether the camera assembly or the electronic device is falling. For example, when the time, during which the acceleration in the Z-axis direction maintains a value equal to or greater than a designated value, exceeds a designated time, the processor may determine that the camera assembly or the electronic device is falling. Herein, the designated time may be set in consideration of a height from which a fall would cause damage to the device (e.g., a free-fall time), or an overall driving time of an actuator (e.g., the OSI actuator or the AF actuator 312 in
