Description

TECHNICAL FIELD

[0001] Embodiments of the disclosure relate to an electronic device including a camera and an operating method thereof. BACKGROUND

[0002] As technology for manufacturing digital cameras has developed, electronic devices equipped with smaller and lighter cameras have been commercialized. The camera mounted in the electronic device enables a user to easily utilize various functions such as a video call or augmented reality, as well as to take a photo or a video.

[0003] The camera can perform an image stabilization function for image correction in response to a disturbance. Here, the disturbance can indicate the occurrence of various artifacts such as blurring of an image obtained by the camera module due to a slight shaking of a user's hand while taking a photo or recording a video. The image stabilization function (e.g., a shake (or hand-shake) correction function) can move a lens assembly included in the camera module on a plane perpendicular to an optical axis to compensate for limited movement of the electronic device due to a jig or a user's grip, thereby preventing or mitigating shaking in a captured image or video. For this purpose, the camera can include a coil and a magnet. The coil supplied with a current can generate an electromagnetic force through electromagnetic interaction with the magnet, and the camera can use the generated electromagnetic force to perform a shake correction function. As a method of correcting shaking using an electromagnetic force, various methods such as lens shift in which a lens assembly is moved, prism shift in which a prism is moved, and module tilt in which the camera is tilted can be applied.

The disclosure may, however, be implemented in several different forms and is not limited to the embodiments described herein. Identical or similar reference numerals can be used to designate identical or similar elements throughout the drawings and their descriptions. In addition, descriptions of well-known functions and configurations incorporated herein can be omitted from the description for clarity and conciseness.

[0036] Figure 1 is a block diagram illustrating an electronic device 101 in a network environment 100 according to various embodiments. Referring to Figure 1 , the electronic device 101 in the network environment 100 can communicate with an electronic device 102 via a first network 198 (e.g., a short-range wireless communication network), or an electronic device 104 or a server 108 via a second network 199 (e.g., a long-range wireless communication network). According to an embodiment, the electronic device 101 can communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 can include a processor 120, a memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a subscriber identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one (e.g., the connection terminal 178) of the above components can be omitted from the electronic device 101, or one or more other components can be added in the electronic device 101. In some embodiments, some of the above components (e.g., the sensor module 176, the camera module 180, or the antenna module 197) can be implemented as a single component (e.g., the display module 160).

[0037] The processor 120 can execute, for example, software (e.g., a program 140) to control at least one other component (e.g., a hardware or software component) of the electronic device 101 coupled with the processor 120 and can perform various data processing or computation.

[0052] The communication module 190 can support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device 101 and an external electronic device (e.g., the electronic device 102, the electronic device 104, or the server 108) and performing communication via the established communication channel. The communication module 190 can include one or more communication processors that are operable independently from the processor 120 (e.g., an application processor (AP)) and supports a direct (e.g., wired) communication or a wireless communication. According to an embodiment, the communication module 190 can include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules can communicate with the external electronic device via the first network 198 (e.g., a short-range communication network, such as BluetoothTM, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network 199 (e.g., a long-range communication network, such as a conventional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules can be implemented as a single component (e.g., a single chip) or can be implemented as separate components (e.g., separate chips) from each other. The wireless communication module 192 can identify and authenticate the electronic device 101 in a communication network, such as the first network 198 or the second network 199, using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module 196.

[0053] The wireless communication module 192 can support 5G networks and next-generation communication technologies (e.g., new radio (NR) access technology) after 4G networks. The NR access technology can support enhanced mobile broadband (eMBB), massive machine type communications (mMTC), or ultra-reliable low-latency communications (URLLC). The wireless communication module 192 can support a high frequency band (e.g., a millimeter wave band) to achieve, for example, high data transmission rates. The wireless communication module 192 can support various technologies for securing performance on a high frequency band, such as, for example, beamforming, massive multiple-input multiple-output (massive MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, or large scale antenna. The wireless communication module 192 can support various requirements designated in the electronic device 101, an external electronic device (e.g., the electronic device 104), or a network system (e.g., the second network 199). According to an embodiment, the wireless communication module 192 can support a peak data rate (e.g., 20 Gbps or more) for implementing eMBB, a loss coverage (e.g., 164 dB or less) for implementing mMTC, or a U-plane latency (e.g., 0.5 ms or less for each of downlink (DL) and uplink (UL), or 1 ms or less of round trip) for implementing URLLC.

[0054] The antenna module 197 can transmit or receive a signal or power to or from the outside (e.g., an external electronic device) of the electronic device 101.

The signal or power can then be transmitted or received between the communication module 190 and an external electronic device via the selected at least one antenna. According to an embodiment, another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element can additionally be formed as part of the antenna module 197.

[0055] According to various embodiments, the antenna module 197 can form a millimeter wave antenna module. According to an embodiment, the millimeter wave antenna module can include a printed circuit board, an RFIC, and a plurality of antennas (e.g., array antennas), in which the RFIC is disposed on a first surface (e.g., a bottom surface) of the printed circuit board, or adjacent to the first surface and capable of supporting a designated high frequency band (e.g., a millimeter wave band), and the plurality of antennas is disposed on a second surface (e.g., a top surface or a side surface) of the printed circuit board, or adjacent to the second surface and capable of transmitting or receiving a signal of the designated high frequency band.

[0056] At least some of the above-described components can be coupled mutually via an inter-peripheral communication scheme (e.g., a bus, a general purpose input output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)) and communicate signals (e.g., commands or data) between them.

[0057] According to an embodiment, commands or data can be transmitted or received between the electronic device 101 and an external electronic device 104 via the server 108 coupled with the second network 199.

According to an embodiment, all or some of the operations to be executed at the electronic device 101 can be executed at one or more of the external electronic devices 102, 104, or server 108. For example, if the electronic device 101 is to automatically perform a function or a service or is to request a function or a service in response to a request from a user or another device, the electronic device 101, instead of, or in addition to, executing the function or the service, can request one or more external electronic devices to execute at least part of the function or the service. The one or more external electronic devices receiving the request can execute at least part of the function or the service requested or an additional function or an additional service related to the request and transfer an execution result to the electronic device 101.

The electronic device 101 can be applied to a smart service (for example, a smart home, a smart city, a smart car, or a health care) based on a 5G communication technology or an IoT-related technology.

[0058] Figure 2 is a block diagram 200 illustrating a camera module 180 according to an embodiment.

[0059] Referring to Figure 2The camera module 180 can include a lens assembly 210, a flash 220, an image sensor 230, an image stabilizer 240, a memory 250 (e.g., a buffer memory), or an image signal processor 260. The lens assembly 210 can collect light emitted or reflected from an object of an image to be photographed. The lens assembly 210 can include one or more lenses. According to an embodiment, the camera module 180 can include a plurality of lens assemblies 210. In this case, the camera module 180 can form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies 210 can have the same lens properties (e.g., angle of view, focal length, auto focus, f number, or optical zoom), or at least one lens assembly can have one or more lens properties different from the lens properties of another lens assembly. The lens assembly 210 can include, for example, a wide-angle lens or a telephoto lens.

[0060] The flash 220 can emit light, in which the emitted light is used to enhance light reflected from the object. According to an embodiment, the flash 220 can include one or more light emitting diodes (LEDs) (e.g., a red green blue (RGB) LED, a white LED, an infrared (IR) LED, or an ultraviolet (UV) LED) or a xenon lamp. The image sensor 230 can obtain an image corresponding to the object by converting light emitted or reflected from the object and transmitted via the lens assembly 210 into an electrical signal. According to an embodiment, the image sensor 230 can include one image sensor selected from a plurality of image sensors having different properties (e.g., an RGB sensor, a black white (BW) sensor, an IR sensor, or a UV sensor), a plurality of image sensors having the same properties, or a plurality of image sensors having different properties. Each of the image sensors included in the image sensor 230 can be implemented using, for example, a charge-coupled device (CCD) sensor or a complementary metal-oxide semiconductor (CMOS) sensor.

[0061] The image stabilizer 240 can move the image sensor 230 or at least one lens included in the lens assembly 210 in a certain direction or control an operable attribute of the image sensor 230 (e.g., adjust a readout timing) in response to a movement of the camera module 180 or the electronic device 101 including the camera module 180. This allows to compensate at least a portion of a negative effect (e.g., image blur) due to a movement of an image being captured. According to an embodiment, the image stabilizer 240 can use a gyro sensor (not shown) or an acceleration sensor (not shown) arranged inside or outside the camera module 180 to sense such a movement of the camera module 180 or the electronic device 101. According to an embodiment, the image stabilizer 240 can be implemented as, for example, an optical image stabilizer. The memory 250 can at least temporarily store at least a portion of an image obtained via the image sensor 230 for a subsequent image processing task. For example, if a plurality of images is captured rapidly or an image capture is delayed due to a shutter lag, an obtained raw image (e.g., a Bayer pattern image, a high resolution image) can be stored in the memory 250, and a corresponding copy image (e.g., a low resolution image) thereof can be previewed via the display module 160. Then, if a specified condition (e.g., by a user’s input or a system command) is satisfied, at least a portion of the raw image stored in the memory 250 can be obtained and processed by, for example, the image signal processor 260. According to an embodiment, the memory 250 can be configured as at least a portion of the memory 130, or the memory 250 can be configured as a separate memory operating independently of the memory 130.

[0062] The image signal processor 260 can perform one or more image processes on an image obtained via the image sensor 230 or an image stored in the memory 250. The one or more image processes can include, for example, depth map generation, three-dimensional (3D) modeling, panorama generation, feature point extraction, image synthesis, or image compensation (e.g., noise reduction, resolution adjustment, brightness adjustment, blurring, sharpening, or softening). Additionally or alternatively, the image signal processor 260 can perform control (e.g., exposure time control or readout timing control) on at least one of the components included in the camera module 180 (e.g., the image sensor 230). An image processed by the image signal processor 260 can be stored back to the memory 250 for further processing, or can be provided to an external component (e.g., the memory 130, the display module 160, the electronic device 102, the electronic device 104, or the server 108) outside the camera module 180. According to an embodiment, the image signal processor 260 can be configured as at least part of the processor 120, or can be configured as a separate processor operating independently of the processor 120. If the image signal processor 260 is configured as a processor separate from the processor 120, at least one image processed by the image signal processor 260 can be displayed as it is by the processor 120 via the display module 160, or can be displayed after being further processed.

[0063] According to an embodiment, the electronic device 101 can include a plurality of camera modules 180 having different attributes or functions. In this case, at least one of the plurality of camera modules 180 can form, for example, a wide-angle camera, and at least another of the plurality of camera modules 180 can form a telephoto camera. Similarly, at least one of the plurality of camera modules 180 can form, for example, a front camera, and at least another of the plurality of camera modules 180 can form a rear camera.

[0066] According to an embodiment, the processor 320 can control overall operations of the electronic device 301. For example, the processor 320 can be implemented identically or similarly to the processor 120 in Figure 1 .

[0067] According to an embodiment, the electronic device 301 can include a plurality of cameras. For example, the plurality of cameras can include a first camera 310 and a second camera 330.

[0123] According to an embodiment, the above description can be equally applied to the second driving unit 332 and the third driving unit 342.

[0124] Referring to Figure 4bIn embodiment (b), the processor 320 can determine the movement of the first x-axis magnet 315a based on the movement of the first camera 310. According to the embodiment, the processor 320 can drive the first x-axis coil 314a to move the first x-axis magnet 315a to a designated position.

According to an embodiment, the processor 320 can confirm the current value 471 (I1) consumed by the first drive unit 312 to move the first x-axis coil 314a to the position corresponding to the designated position.

[0127] Figure 4c This is a circuit diagram showing a portion of the first drive unit according to an embodiment and a graph showing the value of the current consumed by the first drive unit.

[0128] Reference Figure 4c In (a) of the embodiment, processor 320 (e.g., Figure 3a The processor 320 in the process can apply a voltage 480 to the drive circuit. Voltage 480 can represent the voltage output from the drive power supply Vm. According to an embodiment, based on the voltage 480 applied to the drive circuit, the first x-axis coil 314a (e.g., ...) can be driven... Figure 4a The first x-axis coil 314a) is subjected to current or voltage.

[0129] According to an embodiment, processor 320 may use a pulse width modulation (PWM) driving method to apply current or voltage to the first x-axis coil 314a. For example, the PWM driving method may include a method in which processor 320 controls the duty cycle to turn the drive power supply Vm on and off and applies the voltage or current output from the drive power supply Vm to the drive unit (e.g., the coil). For example, the voltage applied to the drive unit by the PWM driving method may include a pulse wave.

[0130] Referring to Figure 4c According to an embodiment, the processor 320 can confirm the current value 481 (I2) consumed by the first driving unit 312 to move the first x-axis magnet 315a to a position corresponding to the designated position.

[0131] According to an embodiment, the processor 320 can confirm the current value 481 (I2) consumed when the first driving unit 312 is driven using a pulse width modulation (PWM) driving method.

[0132] According to an embodiment, the current value 481 consumed when the first driving unit 312 is driven using the PWM driving method can be less than the current value 471 consumed when the first driving unit 312 is driven using a linear driving method.

[0133] According to an embodiment, if there is movement of the first camera 310 that is not obtaining an image, the electronic device 301 (e.g., the electronic device 301 in Figure 3a ) can operate an OIS function or an AF function to move the position of the first magnet 315. According to an embodiment, if there is movement of the first camera 310 that obtained an image but is not displaying the image on the display 360, the electronic device 301 can operate an OIS function or an AF function to move the position of the first magnet 315.

[0134] According to an embodiment, if there is movement of the first camera 310 that is not obtaining an image, the electronic device 301 can operate an OIS function or an AF function to move the position of the first coil 314 (e.g., the first coil 314 in Figure 3a ). According to an embodiment, if there is movement of the first camera 310 that obtained an image but is not displaying the image on the display 360, the electronic device 301 can operate an OIS function or an AF function to move the position of the first coil 314.

[0135] According to an embodiment, when a camera is driven by a PMW driving method, there can be much noise in an image obtained by the camera. Accordingly, the electronic device 301 can drive a camera that obtains an image to be displayed on the display 360 in a linear driving manner so as to obtain a clear image.

[0136] A conventional electronic device including a plurality of cameras can drive both a camera that acquires an image to be displayed on a display and another camera that does not acquire an image to be displayed on the display using a linear driving method. This is caused by the fact that, for an OIS function (or an AF function) of the plurality of cameras, all the cameras are kept in a standby state. However, if the other camera that does not acquire an image to be displayed on the display is driven in a linear manner, excessive power consumption can occur.

[0137] According to an embodiment, the electronic device 301 can drive the first camera 310 that is not acquiring an image using a PWM driving method that consumes less power than a linear driving method, thereby reducing current consumption of the camera.

[0138] The following operations of the electronic device 301 described in the accompanying drawings can be performed by the processor 320. However, for convenience of explanation, the operations performed by the processor 320 will be described as being performed by the electronic device 301.
