Description

Electronic device including a camera, and method of operating the same

[0001] Embodiments of the present disclosure relate to an electronic device including a camera, and a method of operating the same.

[0002] As digital camera technology developed, electronic devices equipped with compact, lightweight cameras became commercially available. With cameras integrated into electronic devices, users could easily take photos and videos, as well as utilize various features like video calls and augmented reality.

[0003] A camera can perform an image stabilization function to compensate for image disturbances. Here, disturbances can be artifacts, such as blurring of images captured by a camera module due to slight hand tremors when a user takes a photo or records a video. An image stabilization function, such as a shake (or hand shake) correction function, can prevent or mitigate shake in captured images or videos by moving a lens assembly included in a camera module along a plane perpendicular to the optical axis to compensate for limited movement of electronic devices due to a fixed device or the user's grip. To this end, the camera can include a coil and a magnet. An energized coil can generate an electromagnetic force through electromagnetic interaction with a magnet, and the camera can perform a shake correction function using the generated electromagnetic force. There are various methods that can be applied to correct shake using electromagnetic force, such as lens shift, which moves the lens assembly, prism shift, which moves the prism, and module tilt, which tilts the camera.

These various types of communication modules can be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips). The wireless communication module (192) can verify or authenticate the electronic device (101) within a communication network such as the first network (198) or the second network (199) by using subscriber information (e.g., an international mobile subscriber identity (IMSI)) stored in the subscriber identification module (196).

[0059] Referring to FIG. 2, the camera module (180) may 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) may collect light emitted from a subject that is a target of image capturing. The lens assembly (210) may include one or more lenses. According to one embodiment, the camera module (180) may include a plurality of lens assemblies (210). In this case, the camera module (180) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies (210) may have the same lens properties (e.g., angle of view, focal length, autofocus, f-number, or optical zoom), or at least one lens assembly may have one or more lens properties that are different from the lens properties of the other lens assemblies. A lens assembly (210) may include, for example, a wide-angle lens or a telephoto lens.

According to one embodiment, the flash (220) can include one or more light-emitting diodes (e.g., red-green-blue (RGB) LED, white LED, infrared LED, or ultraviolet LED), or a xenon lamp. The image sensor (230) can acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through the lens assembly (210) into an electrical signal. According to one embodiment, the image sensor (230) can include one image sensor selected from among image sensors having different properties, such as, for example, an RGB sensor, a black and white (BW) sensor, an IR sensor, or an ultraviolet (UV) sensor, a plurality of image sensors having the same property, or a plurality of image sensors having different properties. Each image sensor included in the image sensor (230) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0061] The image stabilizer (240) can move at least one lens or image sensor (230) included in the lens assembly (210) in a specific direction or control the operating characteristics of the image sensor (230) (e.g., adjust the read-out timing) in response to the movement of the camera module (180) or the electronic device (101) including the same. This allows compensating for at least some of the negative effects of the movement on the captured image. In one embodiment, the image stabilizer (240) can detect such movement of the camera module (180) or the electronic device (101) using a gyro sensor (not shown) or an acceleration sensor (not shown) disposed inside or outside the camera module (180). In one embodiment, the image stabilizer (240) can be implemented as, for example, an optical image stabilizer. The memory (250) can temporarily store at least some of the images acquired through the image sensor (230) for the next image processing task. For example, when image acquisition is delayed due to a shutter, or when multiple images are acquired at high speed, the acquired original image (e.g., a Bayer-patterned image or a high-resolution image) is stored in the memory (250), and a corresponding copy image (e.g., a low-resolution image) can be previewed through the display module (160). Thereafter, when a specified condition is satisfied (e.g., a user input or a system command), at least a portion of the original image stored in the memory (250) can be acquired and processed, for example, by the image signal processor (260). According to one embodiment, the memory (250) may be configured as at least a portion of the memory (130) of FIG. 1, or as a separate memory that operates independently therefrom.

[0062] The image signal processor (260) can perform one or more image processing operations on an image acquired through an image sensor (230) or an image stored in a memory (250). The one or more image processing operations may include, for example, depth map generation, 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) may perform control (e.g., exposure time control, or read-out timing control) on at least one of the components included in the camera module (180) (e.g., image sensor (230)). An image processed by the image signal processor (260) may be stored back in the memory (250) for further processing or provided to an external component of the camera module (180) (e.g., memory (130), display module (160), electronic device (102), electronic device (104), or server (108) of FIG. 1). According to one embodiment, the image signal processor (260) may be configured to perform a control operation (e.g., control) on at least one of the components included in the camera module (180) (e.g., image sensor (230)). It may be configured as at least a part of the processor (120), or may be configured as a separate processor that operates independently of the processor (120). If the image signal processor (260) is configured as a separate processor from the processor (120), at least one image processed by the image signal processor (260) may be displayed through the display module (160) as is or after undergoing additional image processing by the processor (120).

[0063] According to one embodiment, the electronic device (101) may include a plurality of camera modules (180), each having different properties or functions. In this case, for example, at least one of the plurality of camera modules (180) may be a wide-angle camera, and at least another may be a telephoto camera.

[0067] According to one embodiment, the electronic device (301) may include a plurality of cameras. For example, the plurality of cameras may include a first camera (310) and a second camera (330). According to one embodiment, the first camera (310) and the second camera (330) may be implemented in the same or similar manner as the camera module (180) of FIG. 2.

[0127] FIG. 4c is a circuit diagram showing a portion of a first driving unit according to one embodiment and a drawing showing a current consumption value by the first driving unit.

[0128] Referring to (a) of FIG. 4c, according to one embodiment, the processor (320) (e.g., the processor (320) of FIG. 3a) may apply a voltage (480) to the driving circuit. The voltage (480) may represent a voltage output by the driving power source (Vm).

[0130] Referring to (b) of FIG. 4c, according to one embodiment, the processor (320) can check the value (481) (I2) of the current consumed by the first driving unit (312) to move the first x-axis magnet (315a) to a position corresponding to a designated position.

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

According to one embodiment, the electronic device (301) may execute an OIS function or an AF function to move the position of the first magnet (315) when there is movement of the first camera (310) that is acquiring an image and not displaying it on the display (360).

[0134] Depending on the implementation, in one embodiment, the electronic device (301) may execute an OIS function or an AF function to move the position of the first coil (314) (e.g., the first coil (314) of FIG. 3A) when there is movement of the first camera (310) that is not acquiring an image. In one embodiment, the electronic device (301) may execute an OIS function or an AF function to move the position of the first coil (314) when there is movement of the first camera (310) that is acquiring an image and not displaying it on the display (360).

[0135] In one embodiment, when a camera is driven using a PMW driving method, a large amount of noise may be present in the image acquired through the camera. Therefore, the electronic device (301) may drive the camera, which acquires the image displayed on the display (360), using a linear driving method to acquire a clear image.

[0136] Conventional electronic devices comprising multiple cameras can drive both the camera that captures the image displayed on the display and the other cameras that do not capture the image displayed on the display using a linear driving method. This is because, for the OIS (or AF) function of the multiple cameras, all cameras must be kept in a standby state. However, driving the other cameras that do not capture the image displayed on the display using a linear driving method may result in excessive power consumption.

[0137] According to one embodiment, the electronic device (301) can reduce the current consumed by the camera by driving the first camera (310) that is not acquiring an image using a PWM driving method that consumes less power than a linear driving method.

[0138] The operations of the electronic device (301) described in the drawings below may 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).
