Description

Technical Field

[0001] The present disclosure relates to electronic devices and methods for controlling camera motion. Background Art

[0002] There are a variety of electronic devices that can be equipped with cameras to capture images, including smartphones, tablet personal computers (PCs), portable multimedia players (PMPs), personal digital assistants (PDAs), laptop PCs, and wearable devices such as wristwatches or head-mounted displays (HMDs).

[0003] In order to obtain a clear image, the camera of the electronic device needs to stabilize and focus the image.

[0004] The above information is presented as background information only to assist with an understanding of the present 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 respect to the present disclosure. Summary of the invention

[0005] Technical issues

[0006] In order to obtain a clear image, the camera of the electronic device needs to perform image stabilization and focus adjustment. For image stabilization, an optical image stabilizer (OIS) based on lens shift type stabilization or camera tilt type stabilization is often used.

[0007] Lens shift stabilization uses a technique that moves a lens to compensate for the jitter of an optical module. For example, the lens can perform linear motion on a plane parallel to the imaging surface of the image sensor.

[0008] Camera tilt-type stabilization uses a technique for correcting an image by moving a camera lens and an image sensor together. For example, camera tilt-type stabilization matches an optical axis with a virtual axis connecting a target object and a center of a camera module. That is, as the optical axis is tilted to compensate for shake, the virtual axis and the optical axis always coincide with each other, and the image sensor captures an image without blur. However, when camera tilt-type stabilization is used for a camera included in an electronic device with a reduced size, the space for camera movement may be limited.

[0049] To stabilize the image, the camera may use an optical image stabilizer (OIS) based on lens shift type stabilization or camera tilt type stabilization.

[0050] Lens shift stabilization is a technique that uses a moving lens to compensate for the jitter of an optical module. For example, the lens can perform linear motion on a plane parallel to the imaging surface of the image sensor.

[0051] Camera tilt-type stabilization uses a technique for correcting an image by moving a camera lens and an image sensor together. For example, camera tilt-type stabilization matches an optical axis with a virtual axis connecting a target object and a center of a camera module. That is, as the optical axis is tilted to compensate for shake, the virtual axis and the optical axis always coincide with each other, and the image sensor captures an image without blur. However, when camera tilt-type stabilization is used for a camera included in an electronic device of reduced size, such as a smartphone, there may be difficulties due to the small amount of space for camera movement.

[0052] Certain embodiments of the present disclosure provide an electronic device and method for controlling the motion of a camera using camera tilt type stabilization. In addition, certain embodiments of the present disclosure provide an electronic device and method for controlling the motion of a camera at various angles within a limited space to compensate for shaking.

The lens assembly 210 may include, for example, a wide-angle lens or a telephoto lens.

[0084] The flashlight 220 may emit light to enhance the light reflected from the object. The flashlight 220 may include one or more light emitting diodes (LEDs) (e.g., red-green-blue (RGB) LEDs, white LEDs, infrared (IR) LEDs, or ultraviolet (UV) LEDs) or xenon lamps. The image sensor 230 may convert the light collected from the object through the lens assembly 210 into an electrical signal, thereby acquiring an image corresponding to the object. According to an embodiment, the image sensor 230 may include one image sensor selected from image sensors with different properties (such as an RGB sensor, a black and white (BW) sensor, an IR sensor, or a UV sensor), a plurality of image sensors with the same properties, or a plurality of image sensors with different properties. The image sensor 230 may be implemented as, for example, a charge coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor.

[0085] In response to the movement of the camera 180 or the electronic device 101, the image stabilizer 240 may move the image sensor 230 or at least one lens included in the lens assembly 210 in a specific direction, or control the operating characteristics of the sensor 230 (e.g., adjust the readout timing). This may at least partially compensate for the image blur caused by such movement. According to an embodiment, the image stabilizer 240 may detect the movement of the camera 180 or the electronic device 101 by using a gyroscope sensor (not shown) or an acceleration sensor (not shown) provided inside or outside the camera 180. The memory 250 may at least temporarily store at least a portion of the image acquired by the image sensor 230 for subsequent image processing tasks. For example, if image acquisition is delayed due to shutter lag, or if multiple images are acquired quickly, the acquired original image (e.g., an image of a Bayer pattern or a high-resolution image) may be stored in the memory 250, and the corresponding copy image (e.g., a low-resolution image) may be previewed through the display device 160. When a specified condition is met (e.g., when a predetermined user input or system command is received), at least a portion of the original image may be acquired and processed. According to an embodiment, the memory 250 may be configured as at least a portion of the memory 130 or as a separate memory that operates independently of the memory 130 .

[0086] The image signal processor 260 may perform image processing on an image acquired by the image sensor 230 or an image stored in the memory 250. Image processing may include, for example, depth map generation, three-dimensional (3D) modeling, panorama generation, feature point extraction, image synthesis, and / 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 or readout timing control) on at least one component (e.g., image sensor 230) included in the camera 180. The image processed by the image signal processor 260 may be stored again in the memory 250 for further processing or transmitted to an external component (e.g., memory 130, display device 160, electronic device 102, electronic device 104, or server 108) outside the camera 180. According to an embodiment, the image signal processor 260 may be configured as at least a part of the processor 120 or as a separate processor that operates independently of the processor 120. In the latter case, the image processed by the image signal processor 260 may be displayed through the display device 160 as is or after being further processed by the processor 120 .

[0087] According to an embodiment, the electronic device 101 may include a plurality of cameras 180 having different properties (e.g., different viewing angles) or functions. In this case, the plurality of cameras 180 may include, for example, at least one of a wide-angle camera, a telephoto camera, or an IR camera (such as a time-of-flight camera or a structured light camera). For example, a plurality of camera modules including lenses having different viewing angles may be configured, and the electronic device may control the change of the viewing angle in response to a user's selection. According to an embodiment, at least one of the plurality of cameras 180 may be a front camera, and at least one of the other cameras 180 may be a rear camera.

[0088] Figure 3 is a perspective view showing a front surface of the electronic device 101 according to an embodiment of the present disclosure. Figure 4 It is shown Figure 3 A perspective view of the rear surface of electronic device 101 is shown.

In another embodiment (not shown), the housing may refer to a structure forming some of the first surface 110A, the second surface 110B, and the side surface 110C. According to an embodiment, the first surface 110A may be at least partially formed by a substantially transparent front plate 301 (e.g., a polymer plate or a glass plate including various coatings). The second surface 110B may be formed by a substantially opaque rear plate 302. The rear plate 302 may be formed by, for example, coated or colored glass, ceramics, polymers, metals (e.g., aluminum, stainless steel (STS) or magnesium) or a combination of at least two of the above materials. The side surface 110C can be connected to the front panel 301 and the back panel 302 and formed by a side frame structure (or "component" 118 having metal and / or polymer. In some embodiments, the back panel 302 and the side frame structure 118 can be integrally formed and have the same material (e.g., a metal material such as aluminum).

[0090] According to an embodiment, the electronic device 101 may include a display device 160, audio modules 103, 107, and 114, sensor modules 304 and 119, cameras 105 and 112 (eg, Figure 1 and Figure 2 180), key input devices 115, 116, and 117, indicator 106, and at least one of connector ports 308 and 309. In some embodiments, the electronic device 101 may omit at least one of the above components (e.g., key input devices 115, 116, or 217 or indicator 106), or may further include other components.

[0091] Display device 160 may be exposed through a portion of front panel 301. For example, display device 160 may be disposed adjacent to or in conjunction with a touch sensing circuit, a pressure sensor capable of measuring the intensity (or pressure) of a touch, and / or a digitizer capable of detecting a magnetic field type stylus.

[0092] The audio modules 103, 107, and 114 may include a microphone hole 103 and speaker holes 107 and 114. The microphone hole 103 may include a microphone therein for obtaining external sound, and in some embodiments, multiple microphones are included to detect the direction of the sound. The speaker holes 107 and 114 may include an external speaker hole 107 and a call receiver hole 114. In some embodiments, the speaker holes 107 and 114 and the microphone hole 103 may be implemented as one hole, or a speaker (e.g., a piezoelectric speaker) may be included without the speaker holes 107 and 114.

[0093] The sensor modules 304 and 119 may generate an electrical signal or data value corresponding to an internal operating state or an external environmental state of the electronic device 101. The sensor modules 304 and 119 may include, for example: a first sensor module 304 (e.g., a proximity sensor) and / or a second sensor module (not shown) (e.g., a fingerprint sensor), which is disposed near the first surface 110A of the housing 110; and / or a third sensor module 119 (e.g., a heart rate monitor (HRM) sensor), which is disposed near the second surface 110B of the housing 110. The fingerprint sensor may be disposed near the second surface 110B of the housing 110 and the first surface 110A (e.g., the home key button 115).

[0094] The cameras 105 and 112 may include a first camera device 105 (eg, Figure 1 and Figure 2 180), and a second camera device 112 disposed near the second surface 110B (e.g., Figure 1 and Figure 2 Each camera 105 or 112 may include multiple lenses (e.g., Figure 2 lens assembly 210 in), flash 113 (e.g., Figure 2 220 in the flash), an image sensor (e.g., Figure 2 230) and / or an image signal processor (e.g., Figure 2 The image signal processor 260 in the electronic device 101. The flash 213 may include, for example, a light emitting diode or a xenon lamp. In some embodiments, a lens (eg, a wide-angle lens and a telephoto lens) and an image sensor may be provided in the electronic device 101. It can be seen that the camera occupies a small area.

[0095] The key input devices 115, 116, and 117 may include a home key button 115 disposed on the first surface 110A of the housing 110, a touch pad 116 disposed near the home key button 115, and / or a side key button 117 disposed on a side surface 110C of the housing 110. In another embodiment, the electronic device 101 may not include some or all of the above-mentioned key input devices 115, 116, and 117, and the key input device(s) not included may be implemented in any other form (such as soft keys on the display device 160).

[0096] The indicator 106 may be provided on the first surface 110A of the housing 110. The indicator 106 may include a light emitting diode (LED), and may provide, for example, status information of the electronic device 101 in an optical form.

[0097] Connector ports 308 and 309 may include: a first connector port 308 that can receive a connector for sending power and / or data to an external electronic device and receiving power and / or data from an external electronic device; and / or a second connector port 309 that can receive a connector for sending audio signals to an external electronic device and receiving audio signals from an external electronic device.

[0098] Figure 5 1 is a diagram illustrating the operation of the camera 180 including camera tilt according to some embodiments of the present disclosure. The electronic device 101 may include the camera 180. When the user's hand 501 shakes the electronic device 101 (arrow 510), the camera 180 moves, tilts, and moves within the electronic device in a direction opposite to the shaking. As a result, although the electronic device 101 moves relative to the virtual axis 520, the camera 180 maintains a position where the optical axis 521 (the center of the camera 180 to the object 502) coincides with the virtual axis 520.

[0099] It can be seen that the camera 180 has little room for movement. Therefore, there may be limited space for movement of the camera 180 to make the optical axis coincide with the vertical axis. Figure 6 is a perspective view partially transparently illustrating the camera 180 included in the electronic device 101 according to some embodiments of the present disclosure. Figure 7 is a cross-sectional view illustrating a camera 180 included in the electronic device 101 according to some embodiments of the present disclosure. Figure 8 to Figure 1 0B is shown Figure 6 An exploded perspective view of camera 180 is shown.

[0100] Reference Figure 6 to Figure 1 0B, the camera 180 according to some embodiments may include a camera module 610, an image stabilizer actuator 620, a rotation guide 630, and a module housing 640.

[0101] The camera module 610 may include, for example, a lens assembly 611 (eg, Figure 2 The camera module 610 may further include a lens assembly 611 (eg, Figure 2 The image sensor (eg, Figure 2 or Figure 7 230 in the image sensor).

[0102] The lens assembly 611 of the camera module 610 may have an optical axis 601 that is orthogonal to the image sensor 230 .

[0103] The focal length can be adjusted by, for example, the zoom magnification. That is, the focal length can be determined differently depending on the zoom magnification.

[0104] The electronic device 101 may identify the position of a focus lens (e.g., lens assembly 611) for focusing on a target object as a focus position. The focus position refers to a position where a lens (e.g., lens assembly 611) moves in response to proximity, telephoto, etc. and is then placed to focus on a target object.

[0105] To perform the auto focus function, the camera module 610 may be configured to perform the auto focus function on the image signal processor ( Figure 2 260) and / or processor ( Figure 1 A controller of the image sensor 230 (120) uses a motor to move the lens assembly 611 included therein toward or away from the image sensor 230. According to some embodiments, a separate autofocus module can directly control the lens assembly 611 to quickly perform an autofocus function. The autofocus module directly connected to the lens assembly 611 can calculate a focus position based on light acquired through the lens assembly 611, thereby controlling the lens assembly 611. The focus control module may include, for example, an autofocus module. The autofocus module may include a sensor that senses a focus position for a subject and a motor that moves the lens assembly relative to the image sensor to achieve focusing.

[0106] The camera module 610 may further include a lens carrier 612 for moving the lens assembly 611 (see Figure 7 ). The lens assembly 611 is coupled to the lens carrier 612 and can be moved in the direction of the optical axis 601 by movement of the lens carrier 612.

[0107] The lens carrier 612 may include, for example, a magnet and a coil. Under the control of the image signal processor 260 and / or the processor 120, the lens carrier 612 may control the electromagnetic force by controlling the current passing through the coil, and may also move the lens assembly 611 in the direction of the optical axis 601 by using the Lorentz force generated by the electromagnetic force.

[0108] Based on the position of lens assembly 611 during focusing, the range of camera rotation about axes 601 , 602 , and 603 is determined.

[0109] The image stabilizer actuator 620 may include, for example, a first actuator 621 (see Figure 8 ) and the second actuator 622 (see Figure 8 ).

[0110] The camera 180 may detect a motion (eg, shake) of the camera 180 or the electronic device 101 by using a gyro sensor (not shown) or an acceleration sensor (not shown) provided inside or outside the camera.

[0111] Using the first actuator 621 and / or the second actuator 622, the image stabilizer actuator 620 can actuate the camera module 610 to perform a rotational motion relative to a first transverse axis 602 orthogonal to the optical axis 601 and / or a second transverse axis 603 orthogonal to the optical axis 601. The first transverse axis 602 and the second transverse axis 603 may intersect each other substantially perpendicularly on a plane orthogonal to the optical axis 601. The rotational motion of the camera module 610 is not limited to a 2-axis rotational motion relative to the first transverse axis 602 and the second transverse axis 603. In some embodiments, a 3-axis rotational motion around the first transverse axis 602 and the second and 603 and a third axis corresponding to the optical axis 601 may also be possible.

[0112] Each of the first actuator 621 and the second actuator 622 may be composed of a magnet and a coil, and thus move according to a magnetic field. Under the control of the image signal processor 260 and / or the processor 120, the first actuator 621 and the second actuator 622 may control the electromagnetic force by controlling the current passing through the coil, and drive the camera module 610 to rotate around the first horizontal axis 602 and / or the second horizontal axis 603 by using the Lorentz force generated by the electromagnetic force.

[0113] According to some embodiments, the 3-axis rotational motion associated with the motion of the camera module 610 may include yaw motion, pitch motion, and roll motion. For example, the motion associated with the first transverse axis 602 may be referred to as yaw motion, and the motion associated with the second transverse axis 603 may be referred to as pitch motion. In addition, the motion associated with the third axis (e.g., optical axis 601) may be referred to as roll motion. According to some embodiments, the third axis may be an axis perpendicular to the orthogonal plane associated with the yaw motion and the pitch motion.

[0114] According to some embodiments, the electronic device 101 may be implemented to utilize various image stabilization techniques. In one example, the electronic device 101 may control the movement of the camera module 610 through the image stabilizer actuator 620. In another example, the electronic device 101 may also apply lens shift techniques. In yet another example, the electronic device 101 may also apply both lens shift techniques and image sensor shift techniques.

[0115] Reference Figure 8 The camera module 610 may further include a flexible printed circuit board (FPCB) 801, which may transmit an image acquired by the image sensor 230 or transmit an image to / from the image signal processor ( Figure 2 260) and / or processor ( Figure 1 For example, the position information of the lens assembly during focusing can be provided to the processor from the camera module 610. The processor can then determine the range of rotational motion allowed for correcting the shake of the camera module 610.

[0116] Reference Fig. 9 , the rotation guide 630 can be connected with the module housing ( Figure 6 The rotation guide 630 may be combined with the image stabilizer actuator 620 and may provide a rotation guide for the camera module 610 moved by the image stabilizer actuator 620. The rotation guide 630 may include an opening 631 and one or more support portions 632, 633, 634, and 635.

[0117] The opening 631 may prevent the rotating camera module 610 from escaping to the outside of the rotation guide 630. The support portions 632, 633, 634, and 635 may be combined with the module housing 640, and may enable the rotation guide 630 to prevent the camera module 610 from being separated.

[0118] 10A and 10B , the module housing 640 may provide a structure for accommodating the camera module 610, the image stabilizer actuator 620, and the rotation guide 630. The module housing 640 may be combined with at least a portion of the electronic device 101. The module housing 640 may include, for example, a container housing 641 and a connector housing 642. The container housing 641 may be at least partially open and may at least partially accommodate the camera module 610. The connector housing 642 may accommodate and protect the FPCB 801 connected to the camera module 610. Although the FPCB 801 is actually Figure 8 10A is shown connected to the camera module 610 , but in order to clearly show that the connector housing 642 accommodates the FPCB 801 , FIG. 10A shows only a portion of the FPCB 801 without the camera module 610 .

[0119] FIGS. 11A and 11B are diagrams showing one or more camera module stoppers 1101 and 1102 according to certain embodiments of the present disclosure. FIGS. 11C and 11D are diagrams showing movement of the lens assembly 611 for matching the focal length to an object according to certain embodiments of the present disclosure. The camera module stoppers 1101 and 1102 of the camera module 610 shown in FIGS. 11A and 11B may also be included in Figure 5 to Figure 1 In the camera module shown in 0B.

[0120] As the lens assembly 611 moves toward the cover glass 1190 for focusing, the range of movement 1110, 1120 decreases to avoid contact between the camera module 611 and the cover glass 1190. Therefore, the processor selects a different range of movement to correct for shake. Therefore, based on the position of the lens assembly, the processor determines the range to which the camera module 611 can move to correct for shake.

[0121] When the camera module 610 performs a rotational motion by the image stabilizer actuator 620 , the camera module stoppers 1101 and 1102 may contact at least a portion of the rotation guide 630 , thereby limiting a movement angle of the camera module 610 .

[0122] The first camera module stopper 1101 may be provided as at least a portion of the lens assembly 611. When the lens assembly 611 is away from the image sensor 230 along the optical axis 601 (e.g., close-up shooting mode), and when the camera module 610 is rotated around the first lateral axis 602 or the second lateral axis 603 by the image stabilizer actuator 620 to compensate for shake, the first camera module stopper 1101 may contact at least a portion of the rotation guide 630, thereby limiting the moving angle 1110 of the camera module 610. In order to adjust the focus of the target object in the close-up shooting mode, the electronic device 101 may move the lens assembly 611 as far away from the image sensor 230 as possible. Referring to FIG. 11B , the second camera module stopper 1102 may be provided as at least a portion of the side surface of the camera module 610. When the lens assembly 611 is close to the image sensor 230 along the optical axis 601 (for example, a telephoto mode), and when the camera module 610 is rotated around the first lateral axis 602 or the second lateral axis 603 via the image stabilizer actuator 620 to compensate for shake, the second camera module stop 1102 can contact at least a portion of the rotating guide 630, thereby limiting the movement angle 1120 of the camera module 610.

[0123] 11C , when the camera module 610 photographs a nearby object 1150 (ie, a close-up photography mode), the lens assembly 611 moves toward the object 1150 to focus more on the object 1150. That is, the lens assembly 611 moves away from the image sensor 230 and closer to the transparent cover or cover glass 1190.

[0124] Because the lens group 611 is located relatively close to the object 1150, in order to perform a focusing operation in a specific shooting mode, the distance 1151 between the lens assembly 611 and the transparent cover or cover glass 1190 is relatively small. In this disclosure, this distance will be referred to as a first distance 1151.

[0125] If the movement angle of the camera module 610 is large, in the close-up shooting mode, the lens assembly 611 may contact the transparent cover or cover glass 1190 due to the relatively small first distance 1151. Therefore, in order to compensate for the shake, the movement of the camera module 610 may be limited.

[0126] 11D, when the camera module 610 photographs a distant object 1160 (i.e., a telephoto mode), the lens assembly 611 moves away from the object 1160 so as to focus on the object 1160. That is, the lens assembly 611 moves toward the image sensor 230, and the distance 1152 between the lens assembly 611 and the transparent cover or cover glass 1190 is relatively large. In the present disclosure, this distance will be referred to as a second distance 1152. The second distance 1152 is greater than the first distance 1151. Therefore, the movement angle of the camera module 610 is greater in the telephoto mode than in the specific shooting mode. Therefore, the movement angle of the camera module 610 (e.g., 1110 or 1120 in FIG. 11A or FIG. 11B) can be determined differently depending on the position of the lens assembly 611.

[0127] Fig.12 is a flowchart illustrating a method for controlling the motion of the camera 180 included in the electronic device 101 according to some embodiments of the present disclosure.

[0128] Reference Fig.12 , at operation 1201 , the electronic device 101 may activate the camera 180 under the control of the image signal processor 260 and / or the processor 120 .

[0129] At operation 1203, the electronic device 101 may move the position of the lens assembly 611 based on the distance between the object and the image sensor 230 to perform a focusing operation focusing on the target object under the control of the image signal processor 260 and / or the processor 120. According to an embodiment, the camera module 610 may be moved to compensate for shaking.

[0130] According to some embodiments, at operation 1203, the electronic device 101 may move the lens assembly 611 along the optical axis 601 to be closer to or farther from the image sensor 230 under the control of the image signal processor 260 and / or the processor 120. This is a focusing operation of focusing on an object to obtain a clear image of the object.

[0131] At operation 1205 , the electronic device 101 may determine a movement angle range of the camera module 610 corresponding to a movement position of the lens assembly 611 in a focusing operation under the control of the image signal processor 260 and / or the processor 120 .

[0132] According to some embodiments, at operation 1205 , the electronic device 101 may determine a moving position of the lens assembly 611 in a focusing operation based on predefined sections under the control of the image signal processor 260 and / or the processor 120 .

[0133] According to some embodiments, the moving position of the lens assembly 611 may be determined by itself or based on the position of the camera module 610 including the lens assembly 611 or the position of the camera 180. In addition, the moving position of the lens assembly 611 may be determined from the moving speed of the lens assembly 611. In addition, the moving position of the lens assembly 611 may be determined based on a user input such as zooming in or out. For example, when the user inputs a zoom-in input, the electronic device 101 may predetermine the moving position of the lens assembly 611 based on the zoom-in input before the lens assembly 611 moves.

[0134] According to some embodiments, when the user directly selects a specific zoom, the electronic device 101 may pre-acquire a movement position of the lens assembly 611 corresponding to the selected specific zoom. Then, based on the acquired position of the lens assembly 611, the electronic device 101 may determine a movement angle of the camera module 610 (e.g., 1110 in FIG. 11A or 1120 in FIG. 11B ).

[0135] When the moving position of the lens assembly 611 is determined to be one of the predefined segments in the focusing operation, the electronic device 101 can determine the moving angle range of the camera module 610 corresponding to the determined segment under the control of the image signal processor 260 and / or the processor 120 at operation 1205.

[0136] According to some embodiments, at operation 1205 , the electronic device 101 may determine a maximum movement angle of the camera module 610 corresponding to a movement position of the lens assembly 611 in a focusing operation under the control of the image signal processor 260 and / or the processor 120 .

[0137] For example, the maximum movement angle of the camera module 610 may be a maximum angle to which the lens assembly 611 may be movable without contacting a camera window (not shown).

[0138] For example, the maximum movement angle of the camera module 610 can be the maximum angle to which at least a portion of the camera module 610 can move within the electronic device 101 without contacting at least a portion of the mechanical structure (e.g., the module housing 640 or the container housing 641 in Figure 10A).

[0139] According to some embodiments, at operation 1205, information about the position of the lens assembly 611 may be determined based on at least one of a focus position determined by a focus adjustment operation, a physical position of at least one lens in the lens assembly 611, or a numerical value determined by a specified focal length. Based on the determined position information of the lens assembly 611, the electronic device 101 may predict the position of a portion where the lens assembly 611 collides with some components of the camera 180.

[0140] According to some embodiments, at operation 1205, information regarding the position of the lens assembly 611 may be determined based on the focal length determined by the focus adjustment operation.

[0141] At operation 1207 , the electronic device 101 may start camera photography under the control of the image signal processor 260 and / or the processor 120 .

[0142] According to some embodiments, at operation 1207, under the control of the image signal processor 260 and / or the processor 120, the electronic device 101 may move the camera module 610 and then move the camera module 610 when the virtual axis 520 (see FIG. 5 ) connecting the target object and the camera 180 is aligned with the virtual axis 520 (see FIG. 5 ). Figure 5 ) and the optical axis 521 of the camera 180 (see Figure 5 ) coincides with the virtual axis 520. If the virtual axis 520 does not coincide with the optical axis 521 due to shaking, a blurred image may be captured. Therefore, at operation 1207, the electronic device 101 may tilt the optical axis 521 to match the virtual axis 520 to compensate for the shaking, so that the image sensor 230 can capture an image without blur due to the shaking.

[0143] For example, the operation of starting camera photography may include an operation of displaying an image acquired from the camera 180 as a preview image on a display of the electronic device 101 (eg, the display device 160 ).

[0144] Under the control of the image signal processor 260 and / or the processor 120, the electronic device 101 may detect a shake of the camera 180, move the camera module 610 to compensate for the detected shake, and capture an image while minimizing the influence of the shake.

[0145] According to some embodiments, at operation 1207, the electronic device 101 may, under the control of the image signal processor 260 and / or the processor 120, use a sensor module (eg, Figure 1 The movement of the camera 180 or the electronic device 101 is detected by using a sensor (e.g., a gyro sensor, an acceleration sensor) included in the sensor module 176 in the electronic device 101.

[0146] At operation 1207 , under the control of the image signal processor 260 and / or the processor 120 , when any shaking of the camera 180 is detected, the electronic device 101 may move the camera module 610 within the determined movement angle range.

[0147] According to some embodiments, to prevent an image from being blurred due to shaking of the camera 180 , the electronic device 101 may move the camera module 610 in a direction to compensate for the shaking of the camera 180 (eg, in a direction opposite to the shaking of the electronic device 101 ).

[0148] According to some embodiments, the camera module 610 may be moved so that the image of the target object is not blurred due to the shaking of the camera 180 or the electronic device 101. When the shaking of the camera 180 is detected, the electronic device 101 may control the image stabilizer actuator 620 within the determined movement angle range at operation 1207. The image stabilizer actuator 620 may drive the camera module 610 to perform a rotational motion relative to a first transverse axis 602 orthogonal to the optical axis 601 and / or a second transverse axis 603 orthogonal to the optical axis 601 under the control of the image signal processor 260 and / or the processor 120.

[0149] According to some embodiments, at operation 1207, the electronic device 101 may move the camera module 610 based on a movement angle determined depending on the focal length. For example, the electronic device 101 may identify the focal length of the target object and move the camera module 610 in response to the identified focal length. Specifically, if the focal length is a first focal length, the camera module 610 may move within a first movement angle range to compensate for shaking. If the focal length is a second focal length, the camera module 610 may move within a second movement angle range to compensate for shaking. The focal length is the distance between a reference point and a focus where a light beam passing through a lens intersects. For example, when the zoom magnification is in a first magnification state, the distance between the lens and the focus may be referred to as a first focal length, and when the zoom magnification is in a second magnification state, the distance between the lens and the focus may be referred to as a second focal length. The electronic device 101 may identify the focal length of the target object in real time and adjust the movement angle of the camera module 610 differently depending on the identified focal length. The focal length may be changed in response to user input or may be automatically calculated by the camera 180.

[0150] Fig.13 is a flowchart illustrating a method for controlling the motion of the camera 180 included in the electronic device 101 according to some embodiments of the present disclosure.

[0151] Reference Fig.13, at operation 1301, the electronic device 101 may activate the camera 180 under the control of the image signal processor 260 and / or the processor 120. When the camera 180 is activated at operation 1301, the electronic device 101 may capture an image.

[0152] In some embodiments, the operation of capturing an image may be an operation of obtaining an image through the camera 180 of the electronic device 101 .

[0153] In some embodiments, the operation of capturing an image may be an operation of displaying an image acquired from the camera 180 as a preview image on a display of the electronic device 101 (eg, the display device 160 ).

[0154] At operation 1303, the electronic device 101 may move the position of the lens assembly 611 based on the distance between the object and the image sensor 230 to perform a focusing operation focusing on the target object under the control of the image signal processor 260 and / or the processor 120. According to an embodiment, the camera module 610 may be moved to compensate for shaking.

[0155] According to some embodiments, at operation 1303, the electronic device 101 may move the lens assembly 611 along the optical axis 601 to be closer to or farther from the image sensor 230 under the control of the image signal processor 260 and / or the processor 120. This is a focusing operation of focusing on an object to obtain a clear image of the object.

[0156] At operation 1305 , the electronic device 101 may determine a movement angle range of the camera module 610 corresponding to a movement position of the lens assembly 611 in a focusing operation under the control of the image signal processor 260 and / or the processor 120 .

[0157] According to some embodiments, at operation 1305 , the electronic device 101 may determine the movement position of the lens assembly 611 in the focusing operation based on predefined segments under the control of the image signal processor 260 and / or the processor 120 , thereby determining the corresponding movement angle range of the camera module 610 .

[0158] According to some embodiments, the moving position of the lens assembly 611 may be determined by itself or based on the position of the camera module 610 including the lens assembly 611 or the position of the camera 180. In addition, the moving position of the lens assembly 611 may be determined from the moving speed of the lens assembly 611. In addition, the moving position of the lens assembly 611 may be determined based on a user input such as zooming in or out. For example, when the user inputs a zoom-in input, the electronic device 101 may predetermine the moving position of the lens assembly 611 based on the zoom-in input before the lens assembly 611 moves. According to some embodiments, when the user directly selects a specific zoom, the electronic device 101 may pre-obtain the moving position of the lens assembly 611 corresponding to the selected specific zoom. Then, based on the obtained position of the lens assembly 611, the electronic device 101 may determine the moving angle of the camera module 610 (e.g., 1110 in FIG. 11A or 1120 in FIG. 11B).

[0159] When the moving position of the lens assembly 611 is determined to be one of the predefined segments in the focusing operation, the electronic device 101 can determine the moving angle range of the camera module 610 corresponding to the determined segment under the control of the image signal processor 260 and / or the processor 120 at operation 1305.

[0160] According to some embodiments, at operation 1305 , the electronic device 101 may determine a maximum movement angle of the camera module 610 corresponding to a movement position of the lens assembly 611 in a focusing operation under the control of the image signal processor 260 and / or the processor 120 .

[0161] For example, the maximum movement angle of the camera module 610 may be a maximum angle to which the lens assembly 611 may be movable without contacting a camera window (not shown).

[0162] For example, the maximum movement angle of the camera module 610 can be the maximum angle to which at least a portion of the camera module 610 can move within the electronic device 101 without contacting at least a portion of the mechanical structure (e.g., the module housing 640 or the container housing 641 in Figure 10A).

[0163] According to some embodiments, at operation 1305, information about the position of the lens assembly 611 may be determined based on at least one of a focus position determined by a focus adjustment operation, a physical position of at least one lens in the lens assembly 611, or a numerical value determined by a specified focal length. Based on the determined position information of the lens assembly 611, the electronic device 101 may predict the position of a portion where the lens assembly 611 collides with some components of the camera 180.

[0164] According to some embodiments, at operation 1305, information regarding the position of the lens assembly 611 may be determined based on the focal length determined by the focus adjustment operation.

[0165] At operation 1307 , the electronic device 101 may control the camera module 610 under the control of the image signal processor 260 and / or the processor 120 .

[0166] Reference Figure 5 11A to 11D , in some embodiments, the electronic device 101 may control the camera module 610 at operation 1307 so that a virtual axis 520 connecting the target object and the center of the camera 180 coincides with an optical axis 521 of the camera 180 .

[0167] According to some embodiments, at operation 1307 , under the control of the image signal processor 260 and / or the processor 120 , the electronic device 101 may move the camera module 610 to match the virtual axis 520 connecting the object and the camera 180 with the optical axis 521 of the camera 180 .

[0168] If the virtual axis 520 does not coincide with the optical axis 521 due to shaking, a blurred image may be captured. Therefore, at operation 1307, the electronic device 101 can tilt the optical axis 521 to match the virtual axis 520 to compensate for the shaking so that the image sensor 230 can capture an image without blur due to the shaking.

[0169] Under the control of the image signal processor 260 and / or the processor 120, the electronic device 101 may detect a shake of the camera 180, move the camera module 610 to compensate for the detected shake, and capture an image while minimizing the influence of the shake.

[0170] According to some embodiments, at operation 1307, the electronic device 101 may, under the control of the image signal processor 260 and / or the processor 120, use a sensor module (eg, Figure 1 The movement of the camera 180 or the electronic device 101 is detected by using a sensor (e.g., a gyro sensor, an acceleration sensor) included in the sensor module 176 in the electronic device 101.

[0171] At operation 1307 , under the control of the image signal processor 260 and / or the processor 120 , when any shaking of the camera 180 is detected, the electronic device 101 may move the camera module 610 within the determined movement angle range.

[0172] According to some embodiments, to prevent an image from being blurred due to shaking of the camera 180 , the electronic device 101 may move the camera module 610 in a direction to compensate for the shaking of the camera 180 (eg, in a direction opposite to the shaking of the electronic device 101 ).

[0173] According to some embodiments, the camera module 610 may be moved so that an image of a target object is not blurred due to shaking of the camera 180 or the electronic device 101 .

[0174] When the shaking of the camera 180 is detected, the electronic device 101 may control the image stabilizer actuator 620 within the determined movement angle range at operation 1307. The image stabilizer actuator 620 may drive the camera module 610 to perform a rotational movement relative to a first transverse axis 602 orthogonal to the optical axis 601 and / or a second transverse axis 603 orthogonal to the optical axis 601 under the control of the image signal processor 260 and / or the processor 120.

[0175] According to some embodiments, at operation 1307, the electronic device 101 may move the camera module 610 based on a movement angle determined depending on the focal length. For example, the electronic device 101 may identify the focal length of the target object and move the camera module 610 in response to the identified focal length. Specifically, if the focal length is a first focal length, the camera module 610 may move within a first movement angle range to compensate for shaking. If the focal length is a second focal length, the camera module 610 may move within a second movement angle range to compensate for shaking. The focal length is the distance between a reference point and a focus where a light beam passing through a lens intersects. For example, when the zoom magnification is in a first magnification state, the distance between the lens and the focus may be referred to as a first focal length, and when the zoom magnification is in a second magnification state, the distance between the lens and the focus may be referred to as a second focal length. The electronic device 101 may identify the focal length of the target object in real time and adjust the movement angle of the camera module 610 differently depending on the identified focal length. The focal length may be changed in response to user input or may be automatically calculated by the camera 180.

[0176] 14A to 14C are diagrams illustrating a method for controlling a motion of a camera module 610 included in an electronic device 101 according to certain embodiments of the present disclosure.

[0177] FIG. 14A illustrates an image capturing operation using the camera module 610 when the electronic device 101 does not shake.

[0178] According to some embodiments, the electronic device 101 may capture an image of the target object 1410 through the camera module 610. When the electronic device 101 is not shaken, an unblurred image may be captured through the image sensor 230 of the camera module 610. That is, a virtual axis 1420 (e.g., Figure 5 ) and the optical axis 1421 of the lens assembly 611 (e.g., Figure 5 The optical axis 521 and Figure 6 In addition, the optical axis 1421 of the lens assembly 611 is orthogonal to the image sensor 230. Meanwhile, referring to FIG. 14B and FIG. 14C , under the control of the image signal processor 260 and / or the processor 120, any shaking of the electronic device 101 may be detected.

[0179] 14B , according to some embodiments, a virtual axis 1420 connecting the center of the object 1410 and the camera module 610 may not coincide with an optical axis 1421 of the component 611 due to the shaking of the electronic device 101. When the virtual axis 1420 and the optical axis 1421 do not coincide with each other due to the shaking of the electronic device 101, the image sensor 230 may capture a blurred image.

[0180] In FIG. 14C , according to some embodiments, the electronic device 101 may control the camera module 610 so that the virtual axis 1420 and the optical axis 1421 coincide with each other. That is, the electronic device 101 (e.g., the image signal processor 260 and / or the processor 120) may move the camera module 610 so that the optical axis 1421 of the lens assembly 611 matches the virtual axis 1420 connecting the center of the object 1410 and the camera module 610. When the optical axis 1421 of the lens assembly 611 is tilted due to the shaking of the electronic device 101, the electronic device 101 may control (e.g., move) the camera module 610 so that the optical axis 1421 coincides with the virtual axis 1420. Based on this control, the image sensor 230 may capture an image without blurring. That is, the electronic device 101 may detect the shaking of the camera module 610, move the camera module 610 to compensate for the detected shaking, and capture an image while minimizing the influence of the shaking. For example, when the electronic device 101 is shaken, the electronic device 101 may move at a determined movement angle (eg, Fig.12 or Fig.13 The image stabilizer actuator 620 is controlled within a movement angle in (in). Therefore, the image stabilizer actuator 620 can drive the camera module 610 to perform a rotational movement relative to a first transverse axis 602 orthogonal to the optical axis 601 and / or a second transverse axis 603 orthogonal to the optical axis 601.

[0181] However, it is noted that the range to which the camera module 610 can move to compensate for the shake of the electronic device 101 is based on the position of the lens assembly 611 .

[0182] Fig.15 is a flowchart illustrating a method for controlling the motion of the camera 180 included in the electronic device 101 according to some embodiments of the present disclosure. Fig.16 1 is a diagram illustrating first to third moving positions of a lens assembly 611 included in the camera 180 according to certain embodiments of the present disclosure.

[0183] Reference Fig.15 , at operation 1501, the electronic device 101 may activate the camera 180 under the control of the image signal processor 260 and / or the processor 120. When the camera 180 is activated at operation 1501, the electronic device 101 may capture an image.

[0184] In some embodiments, the operation of capturing an image may be an operation of obtaining an image through the camera 180 of the electronic device 101 .

[0185] In some embodiments, the operation of capturing an image may be an operation of displaying an image acquired from the camera 180 as a preview image on a display of the electronic device 101 (eg, the display device 160 ).

[0186] At operation 1503 , the electronic device 101 may move the position of the lens assembly 611 under the control of the image signal processor 260 and / or the processor 120 to perform a focusing operation of focusing on a target object.

[0187] According to some embodiments, at operation 1503, the electronic device 101 may move the lens assembly 611 along the optical axis 601 to be closer to or farther away from the image sensor 230 during a focusing operation under the control of the image signal processor 260 and / or the processor 120. In addition, the lens assembly 611 may be moved with a lens carrier (e.g., Figure 7 or Fig.16 The optical axis 601 is combined with a lens carrier 612 in the optical system and can be moved in the direction of the optical axis 601 by moving the lens carrier 612.

[0188] At operation 1505 , the electronic device 101 may recognize the position of the lens assembly 611 moved in the focusing operation under the control of the image signal processor 260 and / or the processor 120 .

[0189] According to some embodiments, at operation 1505, information about the position of the lens assembly 611 may be determined based on at least one of a focus position determined by a focus adjustment operation, a physical position of at least one lens in the lens assembly 611, or a numerical value determined by a specified focal length. Based on the determined position information of the lens assembly 611, the electronic device 101 may predict the position of a portion where the lens assembly 611 collides with some components of the camera 180.

[0190] According to some embodiments, at operation 1505 , information about the position of the lens assembly 611 may be determined based on the focal length determined by the focus adjustment operation under the control of the image signal processor 260 and / or the processor 120 .

[0191] At operation 1507, when the movement position of the lens assembly 611 caused by the focusing operation is the first position (eg, Fig.16 1601 in the electronic device 101), the electronic device 101 can correct the movement of the camera module 610 within a first movement angle range corresponding to the first position under the control of the image signal processor 260 and / or the processor 120. For example, the first movement angle can be preset and stored within a range where the lens assembly 611 does not collide with a mechanism disposed inside the electronic device 101. In order to compensate for any shaking of the electronic device 101, the electronic device 101 can move the camera module 610 at a certain angle. If the movement position of the lens assembly 611 is the first position (for example, Fig.16 1601), the camera module 610 can only move within the first moving angle range.

[0192] At operation 1507, when the movement position of the lens assembly 611 caused by the focusing operation is the second position (eg, Fig.16 1602 in the figure), the electronic device 101 can correct the movement of the camera module 610 within a second movement angle range corresponding to the second position under the control of the image signal processor 260 and / or the processor 120. For example, the second movement angle can be preset and stored within a range where the lens assembly 611 does not collide with a mechanism disposed inside the electronic device 101. In order to compensate for any shaking of the electronic device 101, the electronic device 101 can move the camera module 610 at a certain angle. If the movement position of the lens assembly 611 is the second position (for example, Fig.16 1602), the camera module 610 can only move within the second moving angle range.

[0193] At operation 1507, when the movement position of the lens assembly 611 caused by the focusing operation is the third position (eg, Fig.161603 in the figure), the electronic device 101 can correct the movement of the camera module 610 within a third movement angle range corresponding to the third position under the control of the image signal processor 260 and / or the processor 120. For example, the third movement angle can be preset and stored within a range where the lens assembly 611 does not collide with a mechanism disposed inside the electronic device 101. In order to compensate for any shaking of the electronic device 101, the electronic device 101 can move the camera module 610 at a certain angle. If the movement position of the lens assembly 611 is the third position (for example, Fig.16 1603), the camera module 610 can only move within the third moving angle range.

[0194] According to some embodiments, at operation 1507, under the control of the image signal processor 260 and / or the processor 120, the electronic device 101 may determine that the movement position of the lens assembly 611 caused by the focusing operation is an infinite focus position as a first position (e.g., Fig.16 1601 in).

[0195] According to some embodiments, at operation 1507, under the control of the image signal processor 260 and / or the processor 120, the electronic device 101 may determine that the movement position of the lens assembly 611 caused by the focusing operation is an intermediate focus position as the second position (e.g., Fig.16 1602 in ).

[0196] According to some embodiments, at operation 1507, under the control of the image signal processor 260 and / or the processor 120, the electronic device 101 may determine that the movement position of the lens assembly 611 caused by the focusing operation is a macro focus position as a third position (e.g., Fig.16 1603 in ).

[0197] According to some embodiments, at operation 1507, the electronic device 101 may move the camera module 610 based on a movement angle determined depending on the focal length. For example, the electronic device 101 may identify the focal length of the target object and move the camera module 610 in response to the identified focal length. Specifically, if the focal length is a first focal length, the camera module 610 may move within a first movement angle range to compensate for shaking. If the focal length is a second focal length, the camera module 610 may move within a second movement angle range to compensate for shaking. For example, when the target object is a near object, the electronic device 101 may determine the focal length of the target object as the first focal length. In this case, the electronic device 101 may move the camera module 610 within a first range by using the image stabilizer actuator 620 to compensate for shaking. The electronic device 101 may identify the focal length of the target object in real time and adjust the movement angle of the camera module 610 differently depending on the identified focal length. The focal length may be changed in response to user input or may be automatically calculated by the camera 180.

[0198] Fig.16 1 is a diagram illustrating first to third moving positions of a lens assembly 611 included in the camera 180 according to certain embodiments of the present disclosure.

[0199] Reference Fig.16 , when the point adjacent to the image sensor 230 is at the lowest position (eg, 0), the lens assembly 611 may be moved from the lowest position to a predetermined maximum height (eg, H).

[0200] For example, when the range from the lowest position (e.g., 0) to the maximum height (e.g., H) is divided into three sections, the first section (0 to 1 / 3H) ranging from the lowest position (e.g., 0) to one third of the maximum height (e.g., 1 / 3H) may be referred to as the first position 1601. When the movement position of the lens assembly 611 caused by the focusing operation is at an infinite focus position, the lens assembly 611 may be located at the first position 1601.

[0201] In addition, a second section (1 / 3H to 2 / 3H) ranging from one third of the maximum height (e.g., 1 / 3H) to two thirds of the maximum height (e.g., 2 / 3H) may be referred to as a second position 1602. The lens assembly 611 may be located at the second position 1602 when the movement position of the lens assembly 611 caused by the focusing operation is at an intermediate focus position.

[0202] In addition, a third section (2 / 3H to H) ranging from two-thirds of the maximum height (e.g., 2 / 3H) to the maximum height (e.g., H) may be referred to as a third position 1603. If the movement position of the lens assembly 611 caused by the focusing operation is in the macro focusing position, the lens assembly 611 may be located at the third position 1603.

[0203] 17A and 17B are diagrams illustrating movement of a camera module 610 included in the electronic device 101 according to some embodiments of the present disclosure.

[0204] FIG. 17A shows a case where there is no movement of the camera module 610 caused by the image stabilizer actuator 620. The lens assembly 611 is coupled to the lens carrier 612 and can be moved in the direction of the optical axis 601 by the movement of the lens carrier 612. The lens carrier 612 may include, for example, a magnet and a coil. Under the control of the image signal processor 260 and / or the processor 120, the lens carrier 612 may control the electromagnetic force by controlling the current passing through the coil, and may also move the lens assembly 611 in the direction of the optical axis 601 by using the Lorentz force generated by the electromagnetic force.

[0205] FIG. 17B shows the lens assembly 611 when it moves to the first, second, or third position (eg, Fig.16 1601, 1602 or 1603 in FIG. ...

[0206] According to some embodiments, the electronic device 101 may identify (or determine) a predetermined moving angle range 1701 based on a specified distance (A) from a surface of a module housing (e.g., 640 in FIG. 10A ) on which the camera module 610 is mounted. That is, when the camera module 610 is placed in the module housing 640, the specified distance (A) may be determined based on a first surface of the module housing on which the image sensor 230 is disposed. The specified distance (A) may include a distance from the first surface of the module housing to a transparent cover or cover glass (e.g., 1190 in FIG. 11C or FIG. 11D ). The electronic device 101 may determine the moving angle range 1701 based on the specified distance (A), and the camera module 610 may compensate for shake without contacting the transparent cover or cover glass 1190. According to some embodiments, the specified distance (A) may be preset in the electronic device 101 and may be variably changed depending on the replacement of the camera module 610.

[0207] According to some embodiments, information about the position of the lens assembly 611 may be determined based on at least one of a focus position determined by a focus adjustment operation, a physical position of at least one lens in the lens assembly 611, or a value determined by a specified focal length. Based on the determined position information of the lens assembly 611, the electronic device 101 may predict the position of a portion where the lens assembly 611 collides with some components of the camera 180.

[0208] According to some embodiments, an electronic device (e.g., electronic device 101) may include a processor (e.g., processor 120) and a camera module (e.g., camera module 610) functionally connected to the processor. The camera module may include a lens assembly (e.g., lens assembly 611) including at least one lens and an image sensor (e.g., image sensor 230) for processing light acquired through the lens assembly. The processor may be configured to recognize position information of the lens assembly, move the camera module within a first range to correct jitter in an image acquired through the image sensor when the position information of the lens assembly corresponds to a first position, and move the camera module within a second range to correct jitter in an image acquired through the image sensor when the position information of the lens assembly corresponds to a second position.

[0209] According to some embodiments, a camera module (eg, camera module 610 ) may further include a focus control module configured to determine position information of a lens assembly (eg, lens assembly 611 ).
