Description

Electronic device including multiple cameras, method for capturing images in the electronic device, and non-transitory storage medium

[0001] The present disclosure relates to an electronic device including a plurality of cameras, a method for capturing images in the electronic device, and a non-transitory storage medium.

[0002] The variety of services and additional features offered through electronic devices, such as smartphones, is steadily increasing. To enhance the utility of these devices and satisfy the diverse needs of users, telecommunications service providers and electronic device manufacturers are competitively developing electronic devices to offer a variety of features and differentiate themselves from competitors. Consequently, the various functions offered through electronic devices are also becoming increasingly sophisticated.

[0003] Recently, technologies have been developed that allow electronic devices to capture images in various ways, including using multiple cameras. Electronic devices can capture stereoscopic images using multiple cameras. Stereoscopic images capture a pair of 2D images that utilize the visual differences between the two eyes to create a three-dimensional sense of depth. Stereoscopic images are fundamentally based on the principle that the images received by each eye differ due to parallax (e.g., binocular parallax) based on the distance between the two eyes, and that this difference is recognized to create a sense of depth. Thus, two images, one for the left and one for the right, are displayed as a pair.

[0004] Electronic devices for capturing stereoscopic images (e.g., spatial video) are applying optical image stabilization (OIS) technology to improve the quality of stereoscopic images. Conventional electronic devices perform this stabilization by moving the sensor when capturing stereoscopic images (e.g., spatial video).

The electronic device (201) can provide an optical image stabilization (OIS) function to capture clear images without shaking when capturing stereoscopic images. According to one embodiment, a “stereo image” is an image acquired through two or more cameras, and can be used to mean a pair of 2D images that enable the perception of a three-dimensional sense of depth by utilizing the difference in visual acuity of both eyes. For example, the stereo image may include a left-eye image corresponding to the left eye and a right-eye image corresponding to the right eye. According to one embodiment, the stereo image may be played back through an electronic device developed to be wearable by a user (e.g., a wearable electronic device such as an augmented reality glass (AR glass), a video see-through (VST) device, or a head-mounted display (HMD) device) and displayed to the user in the form of a 3D image.

[0059] According to one embodiment, the processor (210) may control the camera circuit (220) to perform stereo image capturing, and may control the camera circuit (220) to perform an optical image stabilization (OIS) function to capture clear images without shaking during stereo image capturing.

[0060] According to one embodiment, when a user input (e.g., a touch input or a voice input) for capturing a stereo image is received through the execution screen of a camera application, the processor (210) may detect the inclination of the electronic device (201) through at least one sensor (e.g., a gyroscope sensor or an acceleration sensor) that detects the inclination of the electronic device. The processor (210) of the electronic device (201) according to one embodiment may receive the amount of shaking due to hand shaking detected by the gyro sensor (hereinafter, referred to as the first sensor (231)) and control the driving circuits (e.g., the first driving circuit (225) and the second driving circuit (227)) included in the camera circuit (220) to move the camera lens in the opposite direction to the shaking direction.

[0061] According to one embodiment, the camera circuit (220) may include a plurality of cameras, wherein a front camera among the plurality of cameras may be arranged on a first side (e.g., front) of the housing, and a plurality of rear cameras among the plurality of cameras may be arranged on a second side (e.g., rear) of the housing. The camera circuit (220) may capture a stereo image using at least two of the plurality of rear cameras arranged in a row in a first direction (e.g., Y direction).

[0062] According to one embodiment, the camera circuit (220) may perform an optical image stabilization (OIS) function as an image stabilization function to correct various artifacts, such as blurring of an acquired image caused by slight hand tremors (hand tremors) when a user takes a picture or records a video. The OIS function may prevent or alleviate shaking of a captured image or video by moving a lens assembly or an image sensor included in a camera module on a plane perpendicular to the optical axis to compensate for limited movement of an electronic device due to a fixing device or the user's grip. To this end, the camera circuit (220) may include at least one coil and magnet. The OIS function may be applied in various ways, such as a lens shift that moves a lens assembly, an image sensor shift that moves an image sensor, a prism shift that moves a prism, and a module tilt that tilts the camera module. A camera circuit (220) according to one embodiment may perform image stabilization using a lens shift that moves a lens assembly to synchronize optical image stabilization (OIS) for stereo imaging.

[0063] According to one embodiment, the camera circuit (220) may include a plurality of cameras for capturing stereo images and a plurality of drive circuits for driving the plurality of cameras, respectively. According to one embodiment, the plurality of cameras may include a first camera (221) and a second camera (223) of different types for capturing stereo images. The plurality of drive circuits may include a first drive circuit (driver IC) (225) connected to the first camera (221) and a second drive circuit (driver IC) (227) connected to the second camera (223). The first camera (221) and the second camera (223) of different types may be rear cameras disposed on the rear of the electronic device (201).

[0064] According to one embodiment, the first camera (221) (e.g., the first camera circuit or the first camera module) may include a camera housing (301), a first camera lens (302a), and an image sensor (not shown), and may be a camera capable of optical image stabilization (OIS). According to one embodiment, the first camera housing (301a) may form an exterior of the first camera (221) together with the first camera lens (302a) (e.g., a camera assembly). The first camera lens (302a) may be at least partially accommodated within the first camera housing (301a) and may be positioned in a form that partially protrudes toward the exterior of the first camera housing (301a). The first camera lens (302a) may be fixed or variable in position relative to the first camera housing (301a) according to a focus control operation (e.g., AF) and an image stabilization operation (e.g., OIS), and may focus or guide light (or a light source) incident on the first camera lens (302a) (e.g., lens assembly) into the interior of the first camera housing (301a) while its position relative to the first camera housing (301a) is variable. In one embodiment, the first camera (221) may be, for example, a wide-angle camera. For example, the first camera (221) may perform image stabilization using a lens shift image stabilization (OIS) method that fixes the image sensor and horizontally moves it. In one embodiment, the first drive circuit (225) may move the first camera lens (302a) in the yaw axis (an axis that rotates around the z-axis) or the pitch axis (an axis that rotates around the y-axis).

[0065] In one embodiment, the second camera (223) (e.g., the second camera circuit or the second camera module) may include a second camera housing (301b), a second camera lens (302b), and an image sensor (not shown), and may be a camera capable of optical image stabilization (OIS). In one embodiment, the second camera housing (301b) may form an exterior of the second camera (223) together with the second camera lens (302b) (e.g., the camera assembly). The second camera lens (302b) may be at least partially accommodated within the second camera housing (301b) and may be positioned in a form that partially protrudes toward the exterior of the second camera housing (301b). The second camera lens (302b) may be fixed or variable in position relative to the second camera housing (301b) depending on a focus adjustment operation (e.g., AF) and an optical image stabilization (e.g., OIS) operation, and may focus or guide light (or a light source) incident on the second camera lens (302b) (e.g., lens assembly) into the interior of the second camera housing (301b) while its position relative to the second camera housing (301b) is variable. The second camera (223) may be, for example, a telephoto camera. According to one embodiment, the second driving circuit (227) may move the second camera lens (313) based on the yaw axis (an axis that rotates around the z-axis) or the pitch axis (an axis that rotates around the y-axis).

[0066] According to one embodiment, the camera circuit (220) may use, for example, a driving source including a coil and a magnet as a driving source (e.g., a voice coil motor (VCM) hereinafter referred to as a "VCM"). According to one embodiment, the camera circuit (220) may implement an OIS function and an AF (auto focusing) function through the VCM, respectively. Here, the VCM may control the position of a lens or an image sensor by using an electromagnetic force generated between the coil and the magnet by controlling the current of the coil. The types of VCM may include a solenoid type that generates a driving force by controlling the gap between the coil and the magnet by generating a force in a direction parallel to the direction in which the coil and the magnet face each other, and a Lorenz type that generates a driving force in a state in which the gap between the coil and the magnet is maintained by generating a force in a direction perpendicular to the direction in which the coil and the magnet face each other.

[0067] According to one embodiment, the sensor circuit (230) (e.g., the sensor module (176) of FIG. 1) may include at least one first sensor (231) (e.g., a gyro sensor) capable of detecting shaking due to hand tremors when shooting a stereo image, a second sensor (232) (e.g., a Hall sensor) for detecting a position according to movement of a first camera lens (302a) of a first camera (221), and a third sensor (233) (e.g., a Hall sensor) for detecting a position according to movement of a first camera lens (302b) of a second camera (223). Here, the second sensor (232) may be configured to be included in or connected to the first camera (221). The third sensor (233) may be configured to be included in or connected to the second camera (223). At least one first sensor (231) of the sensor circuit (230) can detect hand tremors and transmit the collected shaking data (e.g., hand tremors information) to the processor (210). In the description of FIG. 2b, the first sensor (231) for detecting hand tremors is described as being included in the sensor circuit (230), but this is not limited thereto, and the first sensor (231) may also be included in the camera circuit (220).

[0068] FIG. 4 is a diagram showing an example of hand shake correction in a camera of an electronic device according to one embodiment, FIG. 5 is a diagram showing an example of movement of a camera lens for hand shake correction in an electronic device according to one embodiment, FIGS. 6a and 6b are diagrams showing an example of movement of a camera lens for hand shake correction in an electronic device according to one embodiment, FIG. 7 is a diagram showing an example of movement of a camera lens for hand shake correction in an electronic device according to one embodiment, and FIGS. 8a, 8b, and 8c are diagrams showing an example of movement of a camera lens for hand shake correction in an electronic device according to one embodiment.

[0069] Referring to FIGS. 2a, 2b, 3a, 3b, 4, 5, 6a, and 6b, an electronic device (201) according to an embodiment (e.g., the electronic device (101) of FIG. 1) can capture a clear image (401a) without shaking by focusing an image at the center position (B) of the image sensor of a camera (e.g., the first camera (221) or the second camera (223)) when there is no hand tremor when capturing a stereo image. When hand tremor occurs when capturing a stereo image, the camera (e.g., the first camera (221) or the second camera (223)) tilts, so that the captured image (401b) is captured at the position B' of the image sensor due to the hand tremor, and thus a blur of B-B' may occur. When there is hand tremors during stereo image shooting, the electronic device (101) can control the camera (e.g., the first camera (221) or the second camera (223)) to move the camera lens (e.g., the first camera lens (302a) or the second camera lens (302b)) in the opposite direction to the movement direction due to the hand tremors by executing a hand tremors correction function to capture a clear image (401a) without shaking.

[0070] According to one embodiment, when a user input (e.g., touch input or voice input) for capturing a stereo image (e.g., spatial video) is received through the execution screen of a camera application, the processor (210) of the electronic device (201) may obtain hand tremor information including a shake value (e.g., yaw / pitch gyro value) through a first sensor (231) (e.g., gyro sensor) that detects shaking due to hand tremor of the electronic device (201).

[0071] According to one embodiment, when a user input for capturing a stereo image is received through the execution screen of a camera application, the processor (210) may obtain first location information including a location value (e.g., yaw / pitch location value) of a first camera lens (302a) from a second sensor (232), and may obtain second location information including a location value (e.g., yaw / pitch location value) of a second camera lens (302b) from a third sensor (233).

[0072] According to one embodiment, the processor (210) can use the hand tremor amount calculation function (510) to determine a first movement amount (e.g., position change amount due to shaking) of a first camera lens (302a) due to hand tremor based on hand tremor information and first position information, and can determine a second movement amount (e.g., position change amount) of a second camera lens (302b) due to hand tremor based on hand tremor information and second position information.

[0073] According to one embodiment, the processor (210) may obtain hand tremor information (e.g., filtered yaw / pitch gyro values) by filtering the shake value (e.g., yaw / pitch gyro values) received from the first sensor (e.g., gyro sensor) (231) using the gyro signal filter function (510). The processor (210) may transmit the hand tremor information (e.g., filtered yaw / pitch gyro values) filtered by the gyro signal filter function (510) to the hand tremor amount calculation function (520).

[0074] According to one embodiment, the processor (210) can use the hand shake calculation function (520) to determine the lens position (e.g., the currently detected yaw / pitch lens position) of the first camera lens (302a) along a specified axis (e.g., the yaw / pitch axis) detected from the second sensor (232), and can determine the lens position (e.g., the currently detected yaw / pitch lens position) of the second camera lens (302b) along a specified axis (e.g., the yaw / pitch axis) detected from the third sensor (233). According to one embodiment, the processor (210) may use the hand shake calculation function (520) to determine (e.g., obtain or calculate) a first movement amount (e.g., shake change amount) of the first camera lens (302a) and a second movement amount (e.g., shake change amount) of the second camera lens (302b) based on the lens position of the first camera lens (302a) and the lens position of the second camera lens (302b). According to one embodiment, the processor (210) may use the hand shake calculation function (520) to set a target movement amount of the designated axis for the hand shake correction based on the first movement amount and the second movement amount. The processor (210) may determine a target lens position (e.g., a yaw / pitch lens position to be moved) to which the first camera lens (302a) and the second camera lens (302b) will each move based on the set target movement amount.

[0075] According to one embodiment, the processor (210) may perform a lens movement simultaneous control function (530) to synchronize the first camera lens (302a) and the second camera lens (302b) to move (e.g., start moving simultaneously) based on a set target movement amount, as illustrated in FIG. 7. The first camera lens (302a) and the second camera lens (302b) may be moved to a position to move based on the set target movement amount in synchronization with each other under the control of the movement simultaneous control function (530). If the movements start simultaneously, the movement speeds may be different, and thus the movement completion times may be different. According to one embodiment, the processor (210) may transmit a signal for continuously monitoring the movement change amount of the first camera lens (302a) and the second camera lens (302b) or the identified target lens position to the lens movement change amount monitoring function (540) using the lens movement simultaneous control function (530).

[0076] According to one embodiment, the processor (210) may transmit a control signal including a position value (e.g., a yaw / pitch target position value) to which the first camera lens (302a) and the second camera lens (302b) are to move based on the identified target movement amount, to the first driver IC (225) and the second driver IC (227), using the lens movement simultaneous control function (530), as illustrated in FIG. 6A. According to one embodiment, the processor (210) may transmit a control signal (e.g., a main camera yaw / pitch signal (each within a range of 0-4095)) including a position value (e.g., a 12-bit signal value) to which the first camera lens (302a) is to move along a specified axis (e.g., a yaw axis or a pitch axis) to the first driver circuit (225). The processor (210) can convert the movement range of the second camera lens (e.g., the sub camera Yaw / Pitch signal (within the range of 0-4095 each)) to match the movement range of the first camera lens (e.g., the main camera yaw / pitch signal (within the range of 0-4095 each)) by using a conversion table (e.g., the conversion table (531) of FIG. 5) designated to synchronize the movement of the first camera lens and the second camera lens using the lens movement simultaneous control function (530). The first camera lens and the second camera lens can be moved in synchronization by a target movement amount within the same movement range. The processor (210) can transmit a control signal (e.g., the sub camera yaw / pitch signal (within the range of 0-4095 each)) for controlling the movement of the second camera lens (302b) to the second driving circuit (227) based on the converted value. The 12-bit values ​​of OIS, 0 and 4095, are the values ​​when moving to the end of each axis, and since the OIS movement ranges of the first camera (221) and the second camera (223) are different, the angular interpretation of each value may be different.The conversion table (531) is a table including values ​​for converting the yaw / pitch signal value of the second camera (225) into a value corresponding to a 12-bit value that matches the movement range of the first camera (221). As illustrated in FIG. 6B, the processor (210) may convert the yaw / pitch 12-bit signal value (0-4095) (e.g., 0.4 mm x 0.4 mm, 97.66 nm per 1) of the second camera (223) to match the yaw / pitch signal value (e.g., 0.35 mm x 0.35 mm, 85.45 nm per 1) which is the movement position value of the first camera (221) in order to set the movement of the first camera (221) (e.g., main camera) and the second camera (223) (e.g., sub camera) to be the same.

[0077] According to one embodiment, the processor (210) transmits control signals to the first driving circuit (225) and the second driving circuit (227), respectively, and then continuously monitors the moved positions (e.g., the amount of movement change) of the first camera lens (302a) and the second camera lens (302b) for hand shake correction using the lens movement change monitoring function (540), and when it is confirmed that the first camera lens (302a) and the second camera lens (302b) have completed moving to the target positions (e.g., are stationary), the processor (210) may control the shooting synchronization circuit (501) to synchronize the shooting signals. Here, the lens movement change monitoring function (540) may be included in the shooting synchronization circuit (501), as illustrated in FIG. 5. However, the present invention is not limited thereto, and the lens movement change monitoring function (540) may also be a function included in the processor (210). As illustrated in FIG. 8A, the lens movement change monitoring function (540) may include a first camera yaw / pitch axis differential signal calculation function (541), a second camera yaw / pitch axis differential signal calculation function (543), and a shooting signal synchronization function (545). The lens movement change monitoring function (540) may obtain (e.g., confirm or identify) differential signals by differentiating the current lens position values ​​of the first camera lens (302a) and the second camera lens (302b) based on a target lens position value (e.g., a yaw or pitch position value to be moved of the first camera lens (302a) and the second camera lens (302b)) or a previous lens position value using the differential signal calculation functions (541, 545), and may synchronize the obtained differential signals using the shooting signal synchronization function (545) to send a shooting request to the processor (210).

[0078] The lens movement change monitoring function (540) of the shooting synchronization circuit (810) according to one embodiment is not configured as hardware (HW), but continuously monitors the positions of the first camera lens (302a) and the second camera lens (302b) using a program as shown in FIGS. 8b and 8c to check the amount of movement change, and may be included in the processor (210) (e.g., application processor (AP) (213)) as a software (SW) function (e.g., operation, program, or module) (hereinafter, referred to as shooting synchronization function) for performing shooting synchronization. Here, the shooting synchronization function may include a lens signal monitoring function and a shooting signal synchronization function.

[0079] According to one embodiment, the processor (210) may continuously monitor the movement positions (e.g., movement change amount) of the first camera lens (302a) and the second camera lens (302b) for hand shake correction using the lens signal monitoring function. According to one embodiment, the processor (210) may monitor the movement of the first camera lens (302a) and the second camera lens (302b), as illustrated in FIGS. 8B and 8C , to check (e.g., identify or obtain) the current lens position value (e.g., currMainLensPosition = AP.getLensPos(0: main)) of the first camera lens (302a) (e.g., main camera) and the current lens position value (e.g., currSubLensPosition = AP.getLensPos(1: sub)) of the second camera lens (313) (e.g., sub camera). According to one embodiment, the processor (210) uses the lens signal monitoring function to determine a target lens position value (e.g., targetLensPosition = AP via dual OIS synchronization in FIG. 8b).The current lens position values ​​of the first camera lens (302a) and the second camera lens (302b) can be obtained (e.g., confirmed or identified) by differentiating the current lens position values ​​of the first camera lens (302a) and the second camera lens (302b) based on the previous lens position values ​​(e.g., prevMainLensPosition, prevSubLensPosition, previous yaw position value, or previous pitch position value in FIG. 8c) or the previous lens position values ​​(e.g., prevMainLensPosition, prevSubLensPosition, previous yaw position value, or previous pitch position value in FIG. 8c). there is.

[0080] According to one embodiment, the processor (210) may transmit a shooting signal (e.g., a shooting request) to the first driving circuit (225) connected to the first camera (221) and the second driving circuit (227) connected to the second camera (223) to simultaneously (e.g., at the same shooting timing) capture images when the acquired difference values ​​satisfy a shooting condition (e.g., if(diffMainLensPosition.magnitude < threshold && diffSubLensPosition.magnitude < threshold)) using a signal synchronization function. According to one embodiment, the processor (210) may identify that the movement of the first camera lens (302a) and the second camera lens (302b) is stopped when the confirmed difference value is 0, and may simultaneously transmit a shooting request signal to the first driving circuit (225) of the first camera (221) and the second driving circuit (227) of the second camera (223).

[0081] FIGS. 9 and 10 are diagrams illustrating an example configuration of a shooting signal synchronization circuit in an electronic device according to one embodiment.

[0082] Referring to FIGS. 9 and 10, according to one embodiment, the photographing signal synchronization circuit (501) may configure a lens movement monitoring circuit (910) as hardware (HW). The lens movement monitoring circuit (910) may include differential signal calculation calculators (911, 913). The lens movement monitoring circuit (810) may continuously monitor the movement positions (e.g., movement change amount) of the first camera lens (302a) and the second camera lens (302a) for hand shake correction. The lens movement monitoring circuit (910) may receive lens signals that monitor the movement of the first camera lens (302a) and the second camera lens (302b) from the second sensor (232) and the third sensor (233), respectively. The lens movement monitoring circuit (910) can check the current lens position value of the first camera lens (302a) and the current lens position value of the second camera lens (302b) based on the received lens signals. The lens movement monitoring circuit (910) can obtain (e.g., confirm or identify) differential signals (e.g., first differential value and second differential value) by differentiating the current lens position values ​​of the first camera lens (302a) and the second camera lens (302b) based on the target lens position value (e.g., yaw or pitch position value to be moved of the first camera lens (302a) and the second camera lens (302b)) or the previous lens position value stored in the previous value storage unit (912, 914) using the differential signal calculators (911, 913). The lens movement monitoring circuit (910) may include inverters (915, 917) connected to each of the first differential signal calculators (911, 913).

[0083] According to one embodiment, the signal synchronizer (920) (e.g., inverter) may transmit a shooting signal to the processor (210) (e.g., application processor (AP) (213)) to simultaneously shoot images when the values ​​of the differential signals received from the differential signal calculators (911, 913) are all 1, as illustrated in FIGS. 9 and 10.

[0084] The shooting synchronization circuit (810) described with reference to FIGS. 9 and 10 may be a hardware (HW) configuration for shooting synchronization configured separately from the processor (210).

[0085] According to one embodiment, when the first driving circuit (225) receives a shooting signal, it can control the driving of the first camera (221) to open the shutter and aperture so that the image sensor is exposed to a light source (e.g., light) to capture an image.

[0086] According to one embodiment, when the second driving circuit (227) receives a shooting signal, it can control the driving of the first camera (221) to open the shutter and aperture to expose the image sensor to a light source (e.g., light) and capture an image. The first camera (221) and the second camera (223) can capture an image simultaneously.

[0087] FIG. 11 is a diagram illustrating an example of a configuration of a camera circuit of an electronic device according to one embodiment, and FIG. 12 is a diagram illustrating an example of a configuration of a camera circuit of an electronic device according to one embodiment.

[0088] Referring to FIGS. 11 and 12, a camera circuit (220) of an electronic device (e.g., the electronic device (101) of FIG. 1) according to one embodiment may place a first camera lens (302a) of a first camera (221) and a second camera lens (302b) of a second camera (223) in one lens frame (1101). The electronic device may enable OIS of the first camera lens (302a) and the second camera lens (302b) by moving the lens frame (1101) even when not taking a picture. The first camera lens (302a) and the second camera lens (302b) may be moved up and down as well as along the yaw / pitch axis, so that the camera circuit (220) may perform AF (auto focus). A camera circuit (220) of an electronic device according to one embodiment can move a lens frame (1101) along a specified axis (e.g., yaw or pitch axis) to move in the opposite direction by an amount of movement change according to hand tremor.

[0089] According to one embodiment, the processor (210) may obtain a sensing value (e.g., a yaw / pitch gyro value) filtered from a sensing value received from a first sensor (e.g., a gyro sensor) (231) using a gyro signal filter function (510) and a change amount monitoring signal or a target lens position. The processor (210) may transmit the hand tremor information including the sensing value (e.g., the filtered yaw / pitch gyro value) filtered by the gyro signal filter function (510) and the change amount monitoring signal or the target lens position to the hand tremor calculation function (520). The hand tremor calculation function (520) may receive the lens position (yaw / pitch lens position) (e.g., the position change amount) of the first camera lens (302a) from the second sensor (232) as input information.

[0090] According to one embodiment, the processor (210) may perform hand tremor calculation based on one of the first camera lens (302a) and the second camera lens (302b) with a smaller amount of movement. For example, the processor (210) may obtain the lens position (yaw / pitch lens position) of the first camera lens (302a) (e.g., first lens position information).

[0091] According to one embodiment, the processor (210) may use the hand shake amount calculation function (520) to determine a first movement amount (e.g., a change amount monitoring signal) of a designated axis according to hand shake of the first camera lens (302a) based on hand shake information and first lens position information, and may determine (e.g., obtain or calculate) a target movement amount (e.g., a target lens position) of the first camera lens (302a) for hand shake correction based on the determined first movement amount. The processor (210) may perform a lens frame control function (1210) to control the movement of the lens frame (1101) so as to move (e.g., synchronize) the first camera lens (302a) and the second camera lens (302b) equally by the determined target movement amount (e.g., to the target lens position). The frame control function (1210) of the processor (210) can transmit a control signal including a target movement amount (e.g., a yaw / pitch position value to be moved) of the first camera lens (302a) and the second camera lens (302b) based on the compensation movement amount to the first driver IC (225) and the second driver IC (227). The processor (210) can simultaneously transmit a shooting signal to the first driver IC (225) and the second driver IC (227) so that images are simultaneously captured by the second processor (AP).

[0092] An electronic device (201) according to one embodiment (e.g., the electronic device (101) of FIG. 1) may implement a software module (e.g., the program (140) of FIG. 1) for stereoscopic image capturing.

At least one processor (210) may execute commands stored in the memory (230) to implement the software module, and control hardware (e.g., the sensor module (176), power management module (188), or communication module (190) of FIG. 1) associated with the function of the software module.

[0093] According to one embodiment, a software module of an electronic device (201) may be configured to include a kernel (or HAL), a framework (e.g., middleware (144) of FIG. 1), and an application (e.g., application (146) of FIG. 1). At least a portion of the software module (201) may be preloaded on the electronic device (101) or may be downloadable from a server (e.g., server (108)).

[0094] According to one embodiment, the application may be configured to include an application (e.g., a module, a manager, or a program) related to stereoscopic image capturing. The application (230) may include an application received from an external electronic device (e.g., a server (108) or an electronic device (102, 104)). According to one embodiment, the application (230) may include a preloaded application or a third party application downloadable from a server. The components and names of the components of the software module according to the illustrated embodiment may vary depending on the type of operating system. According to one embodiment, at least a portion of the software module may be implemented as software, firmware, hardware, or a combination of at least two or more thereof. At least a portion of the software module may be implemented (e.g., executed) by, for example, a processor (e.g., an AP).

In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0111] Referring to FIG. 13, an electronic device according to an embodiment (e.g., the electronic device (101) of FIG. 1, the electronic device (201) of FIGS. 2A and 2B) receives a user input for stereo image capturing in operation 1301, and based on this, detects hand tremor information using a first sensor (e.g., the first sensor (231) of FIG. 2B), first lens position information of a first camera lens (e.g., the first camera lens (302a) of FIG. 3A) of a first camera (e.g., the first camera (221) of FIGS. 2A, 2B, and 3A) detected by a second sensor (e.g., the second sensor (232) of FIG. 2B), and second camera lens (e.g., the second camera (302b) of FIG. 3A) of a second camera (e.g., the second camera (223) of FIGS. 2A, 2B, and 3A) detected by a third sensor. Second lens position information can be obtained.

[0112] In operation 1303, the electronic device can determine the amount of movement (e.g., position change) of the camera lenses due to hand tremor of a specified axis (e.g., yaw or pitch) of the cameras (the first camera and the second camera) based on hand tremor information, first lens position information, and second lens position information. The electronic device can determine the first amount of movement due to hand tremor of the first camera lens based on the hand tremor information and the first lens position information, and can determine the second amount of movement due to hand tremor of the second camera lens based on the sensing information and the second position information.

[0113] In operation 1303, the electronic device may set a target movement amount of a designated axis of the camera lenses based on a first movement amount and a second movement amount, which are movement amounts (e.g., position change amounts) of the camera lenses due to hand tremor. The electronic device may set a target movement amount for synchronizing the movement of the first camera lens and the second camera lens. Here, the target movement amount of the designated axis of the camera lenses may mean a movement amount for moving the camera lenses to a target lens position in the opposite direction to the position to which the camera lenses moved due to hand tremor. The electronic device may convert a movement range of the second camera lens (e.g., a primary camera Yaw / Pitch signal (each within a range of 0-4095)) to match a movement range of the first camera lens (e.g., a primary camera Yaw / Pitch signal (each within a range of 0-4095)) using a conversion table (e.g., a conversion table (531) of FIG. 5) designated to synchronize the movement of the first camera lens and the second camera lens. The first camera lens and the second camera lens can be moved in synchronization by a target movement amount within the same movement range.

[0114] In operation 1305, the electronic device may move the first camera lens by the first driving circuit based on the target movement amount, and may move the second camera lens with the first camera lens by the second driving circuit. The electronic device may transmit a control signal including the target movement amount to the first driving circuit and the second driving circuit, respectively, so that the first camera lens and the second camera lens move in synchronization by the processor. The first driving circuit and the second driving circuit may move the first camera lens and the second camera lens by the target movement amount. According to one embodiment, the electronic device may continuously monitor the position (e.g., movement change amount) of the first camera lens and the position (e.g., movement change amount) of the second camera lens while the first camera lens and the second camera lens move by the target movement amount.

[0115] In operation 1309, the electronic device can determine whether the movement of the first camera lens and the second camera lens is completed based on the monitored position (e.g., change in movement) of the first camera lens and the position (e.g., change in movement) of the second camera lens. If the movement is completed, the electronic device can perform operation 1311, and if the movement is not completed, the electronic device can continue to perform operation 1307.

[0116] In operation 1311, the electronic device can simultaneously transmit a shooting signal to a first driving circuit for driving the first camera and a second driving circuit for driving the second camera based on the completion of movement of the first camera lens and the second camera lens (e.g., the point in time when movement is completed by a target movement amount). The electronic device can simultaneously capture stereo images using the first camera and the second camera to obtain a clear stereo image with hand shake compensation. The electronic device can display the obtained stereo image on a display.

In the following embodiments, the operations may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations may be changed, and at least two operations may be performed in parallel.

[0119] In operation 1403, the electronic device can determine the amount of movement of the camera lenses due to hand shake along a specified axis (e.g., yaw or pitch) of the cameras (the first camera and the second camera) based on the hand shake information and the first lens position information. The electronic device can determine the first amount of movement due to hand shake of the first camera lens based on the hand shake information and the first lens position information.

[0120] In operation 1405, the electronic device may set a target movement amount along a designated axis for compensation of hand shake of the camera lenses based on a first movement amount, which is a movement amount of the camera lenses due to hand shake. Here, the target movement amount along the designated axis may refer to a movement amount for moving the camera lenses in the opposite direction to a target position for compensation of hand shake from a position where the camera lenses moved due to hand shake.

[0121] In operation 1407, the electronic device may control the movement of the lens frame based on the target movement amount. The electronic device may transmit a control signal including the target movement amount to the lens frame so that the first camera lens and the second camera lens may be moved by the processor. The lens frame may be moved by the target movement amount through the lens frame control function of the processor. According to one embodiment, the electronic device may continuously monitor the position (e.g., the change in movement amount) of the lens frame while the lens frame is moved in synchronization by the target movement amount.

[0122] In operation 1409, the electronic device can determine whether the movement of the lens frame is complete based on the monitored position of the lens frame (e.g., the amount of change in movement). If the determination result indicates that the movement is complete, the electronic device can perform operation 1411. If the movement is not complete, the electronic device can continue to perform operation 1407.

[0123] In operation 1411, the electronic device can simultaneously transmit a shooting signal to a first driving circuit driving a first camera and a second driving circuit driving a second camera based on the completion of movement of the lens frame (e.g., the point in time when movement is completed by a target movement amount). The electronic device can simultaneously capture stereo images using the first camera and the second camera to obtain a clear stereo image with hand shake compensation. The electronic device can display the obtained stereo image on a display.
