[0042] FIG. 3 is a flowchart illustrating an electronic device according to one embodiment calculating the amount of center point movement up to the final magnification and moving the center point. Content similar to or overlapping with the foregoing in relation to FIG. 3 may be simplified or omitted.

[0043] Referring to FIG. 3, a processor (110) according to one embodiment can obtain user input in operation 301. According to one embodiment, the processor (110) can display at least two icons among a first object corresponding to a first camera (e.g., tele camera), a second object corresponding to a second camera (e.g., wide camera), and a third object corresponding to a third camera (e.g., ultra-wide camera) in at least a portion of a display (130). According to one embodiment, the processor (110) can obtain user input for a first object corresponding to a first camera, a second object corresponding to a second camera, or a third object corresponding to a third camera.

[0044] According to one embodiment, the processor (110) may display a slide bar on the display (130) that slides according to a magnification that changes by a zoom-in or zoom-out operation. According to one embodiment, the processor (110) may obtain user input (e.g., tap, drag) for the slide bar.

[0045] According to one embodiment, the processor (110) may obtain user input for pinch zoom. According to one embodiment, the pinch zoom operation may mean that the content displayed on the display (130) is zoomed in or zoomed out as two fingers of the user that were spread out and apart come close together on the display (130) or as two fingers of the user that were close together and come close together come apart on the display (130).

[0046] According to one embodiment, the processor (110) may obtain user input for button zoom. According to one embodiment, the button zoom operation may mean that content displayed on the display (130) is zoomed in or zoomed out based on an object (e.g., an icon) and / or a hardware button that corresponds to a specified zoom scale displayed through the display (130). According to one embodiment, the processor (110) may perform a zoom operation based on multiple user inputs. For example, when the processor (110) obtains user input sequentially or simultaneously for an object (e.g., an icon) corresponding to a first scale and a second scale, it may zoom in or zoom out the content displayed on the display (130) in the order of the first scale and the second scale (or the second scale and the first scale).

[0047] According to one embodiment, the processor (110) may determine (determine) the final scale based on an intermediate scale between the initial scale and the final scale. For example, the processor (110) may predict the final scale by applying the same change time from the intermediate scale to the final scale based on the change time between the initial scale and the intermediate scale.

[0048] According to one embodiment, the processor (110) can calculate the amount of center point movement from the initial scale to the final scale using mathematical formula 1 in operation 303.

[0049]

[0050] In Equation 1, Pi represents the center of the image at the initial magnification, Pf represents the center of the image at the final magnification, and Pc represents the center of the image at the current magnification. Xi represents the initial magnification, Xf represents the final magnification, and Xc represents the current magnification.

[0051] According to one embodiment, the processor (110) can calculate the amount of center point movement of a preview image from an initial magnification to a final magnification in response to receiving user input. For example, the processor (110) can calculate the amount of center point movement to a magnification corresponding to an object in response to receiving touch input for an object displayed on the display (130). For example, the processor (110) can calculate the amount of center point movement from the first magnification to the second magnification in response to touch input for an object corresponding to the second magnification (e.g., x1.0 magnification) while the image received at the first magnification (e.g., x5.0 magnification) is displayed on the display (130).

[0052] According to one embodiment, the processor (110) can calculate the camera switching scale in operation 305. According to one embodiment, the camera switching scale may mean a specified scale at which the camera is switched. For example, if the scale at which the camera is switched from a telephoto camera to a wide-angle camera is a first scale (e.g., x5.0 scale), the camera switching scale may be the first scale.

[0053] According to one embodiment, the processor (110) can obtain an offset value from camera calibration. According to one embodiment, the processor (110) can calculate a camera switching magnification based on the offset value obtained from calibration and the center position of the field of view of the camera (e.g., telecamera). For example, the offset value may be determined based on the tilt angle or tolerance of the camera occurring during design or assembly.

[0054] According to one embodiment, the processor (110) can gradually shift the center of the preview using an offset value obtained through camera calibration when the center of the field of view (FOV) of the camera (120) differs between cameras. According to one embodiment, deviations in the optical axis that occur during manufacturing can be corrected using an offset value obtained through camera calibration. For example, deviations in the optical axis caused by manufacturing errors that may occur during the manufacturing of the camera (120) (or camera module) and / or assembly errors that may occur when the camera (120) is placed in the electronic device (100) can be corrected using an offset value obtained through camera calibration. For example, as shown in FIG. 4b and / or FIG. 5b, the processor (110) can linearly shift the center of the preview image while the magnification of the camera (120) is changed.

[0055] According to one embodiment, the processor (110) can calculate the camera switching ratio as x1.125 when switching from a state of acquiring an image with a wide camera to an ultra-wide camera.

[0056] According to one embodiment, the processor (110) may determine the center of the field of view location based on the area displayed through the display (130). For example, if the field of view (or field of view area) of the camera (120) includes an area smaller than the sensing area of ​​the image sensor (e.g., image sensor (730) of FIG. 7) included in the camera (120) (e.g., camera module (680) of FIG. 7), the processor (110) may determine the center of the field of view of the camera (120) as the center of the area displayed through the display (130), rather than the center of the image sensor, as the center of the field of view of the camera (120).

[0057] According to one embodiment, the processor (110) can check the current scale in operation 307 and determine the amount of center point movement. According to one embodiment, the processor (110) can check the current scale while the scale changes from an initial scale to a final scale.

[0058] According to one embodiment, the processor (110) can move the center point of the preview image in operation 309. According to one embodiment, the processor (110) can move the center point of the preview image as the magnification of the camera (120) transitions from an initial magnification to a final magnification. According to one embodiment, the processor (110) can change the center point of the preview image displayed on the display (130) gradually (or linearly) as the magnification of the camera (120) changes gradually (or linearly) from an initial magnification to a final magnification.

[0059] According to one embodiment, the processor (110) can determine whether the current magnification in operation 311 is equal to the camera switching magnification. According to one embodiment, the processor (110) can determine whether the current magnification of the camera (120) is equal to the camera switching magnification calculated based on the offset obtained by camera calibration. For example, the processor (110) can determine whether the magnification becomes the magnification that switches to a wide camera (e.g., x5.0 magnification) while the telecam is in operation. Also, for example, the processor (110) can determine whether the camera switching magnification becomes the magnification that switches from a wide camera to an ultra-wide camera (e.g., x1.125 magnification).

[0060] According to one embodiment, the processor (110) may switch the main camera in operation 313 when it is determined that the current magnification is the same as the camera switching magnification. According to one embodiment, the processor (110) may switch the main camera to a wide camera in response to the current magnification becoming the camera switching magnification (e.g., x5.0 magnification) while acquiring an image using a tele camera. According to one embodiment, the processor (110) may switch the main camera to an ultra-wide camera in response to the current magnification becoming the camera switching magnification (e.g., x1.125 magnification) while acquiring an image using a wide camera.

[0061] According to one embodiment, the processor (110) can acquire an image using the main camera in response to the main camera being switched.

[0062] According to one embodiment, the processor (110) may display a preview of an image acquired through the camera in operation 315 on the screen when it is determined that the current magnification is not the same as the camera switching magnification. According to one embodiment, when the processor (110) determines that the current magnification is not the same as the camera switching magnification, it may display a preview of an image acquired through the first camera on the display (130) without switching the main camera from the first camera to the second camera.

[0063] According to one embodiment, the processor (110) can determine whether the current scale is equal to the final scale in operation 317. According to one embodiment, the processor (110) can determine whether the current scale becomes the final scale corresponding to the user input (e.g., x5.0 scale).

[0064] According to one embodiment, the processor (110) may terminate the zoom operation if it is determined that the current magnification is the same as the final magnification. According to one embodiment, if the processor (110) is not determined that the current magnification is the same as the final magnification, it may return to operation 307 to check the current magnification and determine the amount of center point movement.

According to one embodiment, the camera module (680) may include a plurality of lens assemblies (710). In this case, the camera module (680) may form, for example, a dual camera, a 360-degree camera, or a spherical camera. Some of the plurality of lens assemblies (710) 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 different from the lens properties of other lens assemblies. The lens assemblies (710) may include, for example, wide-angle lenses or telephoto lenses.

[0110] A flash (720) may emit light used to enhance light emitted or reflected from a subject. According to one embodiment, the flash (720) may include one or more light-emitting diodes (e.g., RGB (red-green-blue) LED, white LED, infrared LED, or ultraviolet LED), or a xenon lamp. An image sensor (730) may acquire an image corresponding to the subject by converting light emitted or reflected from the subject and transmitted through the lens assembly (710) into an electrical signal. According to one embodiment, the image sensor (730) may include, for example, one image sensor selected from image sensors with different properties such as an RGB sensor, a BW (black and white) 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 image sensor included in the image sensor (730) can be implemented using, for example, a CCD (charged coupled device) sensor or a CMOS (complementary metal oxide semiconductor) sensor.

[0111] The image stabilizer (740) may move at least one lens or image sensor (730) included in the lens assembly (710) in a specific direction or control the operational characteristics of the image sensor (730) (e.g., adjusting read-out timing) in response to the movement of the camera module (680) or the electronic device (601) containing it. This allows for compensating for at least some of the negative effects caused by the movement on the image being captured. According to one embodiment, the image stabilizer (740) may detect such movement of the camera module (680) or the electronic device (601) using a gyroscope sensor (not shown) or an accelerometer sensor (not shown) placed inside or outside the camera module (680).

The memory (750) may temporarily store at least a portion of the image acquired through the image sensor (730) for the next image processing operation. For example, if image acquisition by the shutter is delayed or 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 (750), and the corresponding copy image (e.g., a low-resolution image) can be previewed through the display device (660). Subsequently, when a specified condition is satisfied (e.g., user input or system command), at least a portion of the original image stored in the memory (750) may be acquired and processed, for example, by an image signal processor (760). According to one embodiment, the memory (750) may be composed of at least a portion of the memory (630) or a separate memory that operates independently thereof.

[0112] The image signal processor (760) can perform one or more image processing operations on an image obtained through the image sensor (730) or an image stored in memory (750). One or more of the above image processing 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 softing). Additionally or generally, the image signal processor (760) may perform control (e.g., exposure time control, or readout timing control, etc.) over at least one of the components included in the camera module (680) (e.g., image sensor (730)). The image processed by the image signal processor (760) may be stored back in memory (750) for further processing or provided to an external component of the camera module (680) (e.g., memory (630), display device (660), electronic device (602), electronic device (604), or server (608)).
