According to an embodiment, the flash  220  may 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  may obtain an image corresponding to an 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  may include one selected from image sensors having different attributes, such as a RGB sensor, a black-and-white (BW) sensor, an IR sensor, or a UV sensor, a plurality of image sensors having the same attribute, or a plurality of image sensors having different attributes. Each image sensor included in the image sensor  230  may be implemented using, for example, a charged coupled device (CCD) sensor or a complementary metal oxide semiconductor (CMOS) sensor. 
     The image stabilizer  240  may move the image sensor  230  or at least one lens included in the lens assembly  210  in a particular direction, or control an operational attribute (e.g., adjust the read-out timing) of the image sensor  230  in response to the movement of the camera module  180  or the electronic device  101  including the camera module  180 . This allows compensating for at least part of a negative effect (e.g., image blurring) by the movement on an image being captured. According to an embodiment, the image stabilizer  240  may sense such a movement by 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 . According to an embodiment, the image stabilizer  240  may be implemented, for example, as an optical image stabilizer. The memory  250  may store, at least temporarily, at least part of an image obtained via the image sensor  230  for a subsequent image processing task. For example, if image capturing is delayed due to shutter lag or multiple images are quickly captured, a raw image obtained (e.g., a Bayer-patterned image, a high-resolution image) may be stored in the memory  250 , and its corresponding copy image (e.g., a low-resolution image) may be previewed via the display module  160 . Thereafter, if a specified condition is met (e.g., by a user&#39;s input or system command), at least part of the raw image stored in the memory  250  may be obtained and processed, for example, by the image signal processor  260 . According to an embodiment, the memory  250  may be configured as at least part of the memory  130  or as a separate memory that is operated independently from the memory  130 . 
     The image signal processor  260  may perform one or more image processing with respect to an image obtained via the image sensor  230  or an image stored in the memory  250 . The one or more image processing may include, for example, depth map generation, three-dimensional (3D) modeling, panorama generation, feature point extraction, image synthesizing, 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) with respect to at least one (e.g., the image sensor  230 ) of the components included in the camera module  180 . An image processed by the image signal processor  260  may be stored back in the memory  250  for further processing, or may 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  may be configured as at least part of the processor  120 , or as a separate processor that is operated independently from 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, by the processor  120 , via the display module  160  as it is or after being further processed. 
     According to an embodiment, the electronic device  101  may include a plurality of camera modules  180  having different attributes or functions. In such a case, at least one of the plurality of camera modules  180  may form, for example, a wide-angle camera and at least another of the plurality of camera modules  180  may form a telephoto camera. Similarly, at least one of the plurality of camera modules  180  may form, for example, a front camera and at least another of the plurality of camera modules  180  may form a rear camera.

The processor  120  may configure an object desired to be tracked as a focused subject. The processor  120  may transmit a control signal of the camera module  180  for tracking an object to the camera module  180 . For example, the camera module  180  may change the direction in which the lens assembly  210  faces, based on the control signal. 
     In an embodiment, the processor  120  may track an object from image data by moving at least a portion of the electronic device  101 . For example, the electronic device  101  (e.g., an electronic device implemented in the form of a robot) may further include a driving unit (e.g., a motor) that can move the position of the electronic device  101  or move the direction in which the electronic device  101  (e.g., the camera module  180 ) faces.

For example, in a case in which an object corresponding to a subject is not included in the range of the angle of view of the camera module  180  when the subject approaches the electronic device  101 , the processor  120  may move the position of the electronic device  101  through the driving unit such that the electronic device  101  moves away from the subject to enable the object to be maintained at a designated size in the video. 
     In an embodiment, in a case in which the electronic device  101  is mounted on an external electronic device (e.g., a gimbal) capable of moving the electronic device  101 , the processor  120  may control the external electronic device such that the object is maintained at a designated size in the video (or the object is included in the video). For example, in a case in which an object corresponding to a subject is not included in the range of the angle of view of the camera module  180  when the subject approaches the electronic device  101 , the processor  120  may transmit a signal for moving the external electronic device away from the subject through the communication module  190  to enable the object to be maintained at a designated size in the video.

       FIG.  4    is an overall flowchart  400  illustrating an example method for providing a video, according to various embodiments. 
     Referring to  FIG.  4   , in an embodiment, in operation  401 , the processor  120  may acquire a first video (hereinafter, referred to as a “first video”). In an embodiment, the first video may also be referred to as a “reference video”. 
     In an embodiment, the first video may be a video stored in the memory  130  before acquiring (e.g., capturing) a video (e.g., a second video to be described later) through the camera module  180 . The processor  120  may acquire the first video from the memory  130 . 
     In an embodiment, the first video may be a video acquired in real time through the communication module  190  using a streaming service. The processor  120  may acquire the first video from the outside (e.g., a server providing a streaming service) through the communication module  190 . 
     However, a method for acquiring a first video is not limited to the above-described examples. 
     In an embodiment, in a case in which a plurality of videos are stored in the memory  130 , the processor  120  may select, automatically (e.g., in a designated manner) or based on a user input, a first video from among the plurality of videos to acquire the first video. Various embodiments of a method for acquiring a first video by selecting the first video from among a plurality of videos will be described later in detail with reference to  FIG.  15   . 
     According to an embodiment, in operation  403 , the processor  120  may identify (e.g., detect) a first object (hereinafter, referred to as a “first object”) in the first video. 
     In an embodiment, the processor  120  may identify, in a plurality of images (e.g., a plurality of image frames) of a first video, at least one first object corresponding to at least one subject (e.g., a person). For example, the processor  120  may detect at least one object from the plurality of images of the first video using a designated algorithm (e.g., a person detection algorithm or a face detection algorithm). 
     Various embodiments of an operation for identifying a first object in a first video will be described in detail below with reference to  FIG.  5   . 
       FIG.  5    is a diagram  500  for explaining an example method for identifying a first object in a first video, according to various embodiments. 
     Referring to  FIG.  5   , in an embodiment, the processor  120  may identify (e.g., detect) a first object  511  from an image  510  of a first video. In a case in which the first object  511  is identified from the image  510  of the first video, the processor  120  may determine (e.g., configure) a tracking region  513  for the first object  511 . The tracking region  513  may be in the form of a bounding box surrounding the first object within the image  510  of the first video. However, the form of the tracking region  513  is not limited thereto. 
     In an embodiment, the processor  120  may identify a first object  521  from an image  520  of the first video. The processor  120  may obtain (extract) feature points (e.g., key points) related to skeleton of the first object  521  (e.g., an object corresponding to a person) within the image  520  of the first video. The processor  120  may determine the skeletons  522  of the first object  521  by connecting the feature points, based on the feature points related to the skeletons  522 . The processor  120  may determine a tracking region  523  surrounding the skeletons  522  of the first object  521 , based on the skeletons of the first object  521 . 
     In an embodiment, the processor  120  may identify a plurality of first objects  531 - 1  and  531 - 2  from an image  530  of the first video. In a case in which the plurality of first objects  531 - 1  and  531 - 2  are identified from the image  530  of the first video, the processor  120  may determine tracking regions for the plurality of first objects  531 - 1  and  531 - 2 . For example, the processor  120  may determine the respective tracking regions  533 - 1  and  533 - 2  for the plurality of first objects  531 - 1  and  531 - 2 . As another example, the processor  120  may determine a tracking region (not shown) for a region (e.g., union of regions including the plurality of first objects  531 - 1  and  531 - 2 , respectively). In an embodiment, the position and size of the first object may correspond, for example, to the position and size of the tracking region for the first object. Hereinafter, it may be understood that the description of the position and size of the first object includes, for example, the description of the position and size of the tracking region of the first object. 
     Referring back to  FIG.  4   , in operation  405 , in an embodiment, the processor  120  may obtain (acquire) a parameter (hereinafter, interchangeably used with a “default parameter” or a “zoom region-related default parameter”), based on movement of the first object in the first video. The default parameter may include a parameter to be applied (or configured) to the second video. For example, the default parameter may include at least one of a threshold value (a first threshold value) associated with movement of the zoom region, a movement speed of the zoom region of the second video, and/or a padding region (e.g., the size of a padding region) of the zoom region to be applied to the second video. 
     In an embodiment, the processor  120  may obtain information on the movement of the first object from the first video. In an embodiment, the information on the movement of the first object may include at least one of a region in which the first object has moved within the first video, an average movement speed (and/or maximum movement speed and minimum movement speed) of the first object, or the amount of change in the position and size of the first object. 
     According to an embodiment, the region in which the first object has moved within the first video may include regions of a plurality of images of the first video in which the first object has been positioned (e.g., moved). For example, the region in which the first object has moved within the first video may be a union of regions of the plurality of images of the first video in which the first object has been positioned. 
     In an embodiment, the average movement speed of the first object may be a value obtained by dividing a value (e.g., a movement distance of the first object) obtained by summing the amounts of changes in the position of the first object in the plurality of images of the first video by a time during which a plurality of images of the first video are acquired. In an embodiment, the maximum movement speed of the first object may be the maximum amount of change in the position of the first object per unit time (e.g., a time interval at which each of the plurality of images is acquired) in the plurality of images of the first video. In an embodiment, the minimum movement speed of the first object may be the minimum amount of change in the position of the first object per unit time in the plurality of images of the first video. 
     In an embodiment, the amount of change in the position and size of the first object (e.g., the average amount of change in the position and size of the first object) may include the number of movements of the first object (e.g., the number of movements detected during a designated time). For example, as the number of changes in the position of a subject (e.g., changes in the upper/lower/left/right positions of a subject in a plurality of images) increases during a designated time, the amount of change in the position of a first object corresponding to the subject may increase. As another example, as the number of movements approaching or moving away from the electronic device  101  (e.g., the camera module  180 ) of the subject increases, the amount of change in which the size of the first object is increased or decreased may increase. In an embodiment, the amount of change in the position and size of the first object may be referred to as variance of movement of the first object. 
     In an embodiment, in a case in which a plurality of first objects are included in the first video, the processor  120  may obtain information on movement of each of the plurality of first objects. 
     In an embodiment, in a case in which a plurality of first objects are included in the first video, the processor  120  may obtain information on movements of all of the plurality of first objects. For example, in a case in which a plurality of first objects are included in the first video as in the image  530  in  FIG.  5   , the processor  120  may determine a tracking region for a region including all of the plurality of first objects (e.g., a union of regions including the plurality of first objects). The processor  120  may acquire information on movements of all of the plurality of first objects by acquiring information on change in the determined tracking region. 
     In an embodiment, in a case in which a plurality of first objects are included in the first video, the processor  120  may acquire information on movement of each of the plurality of first objects, and information on movements of all of the plurality of first objects. 
     In an embodiment, the processor  120  may obtain a parameter related to a zoom region, based on the obtained information on the movement of the first object. For example, the processor  120  may obtain a parameter related to a zoom region to be applied to a video (hereinafter referred to as a “second video”) to be acquired through the camera module  180 , based on the acquired information on the movement of the first object. 
     In an embodiment, the processor  120  may obtain a threshold value (hereinafter, referred to as a “first threshold value”) related to movement of a zoom region to be applied to a second video, based on the region in which the first object has moved within the first video. For example, the processor  120  may determine (e.g., configure) the first threshold value to be lower as the region in which the first object has moved within the first video is larger (e.g., wider). The processor  120  may determine (e.g., configure) the first threshold value to be higher as the region in which the first object has moved within the first video is smaller (e.g., narrower). 
     In an embodiment, the first threshold value may be a value for determining whether to move the position of the zoom region of the first video in a second video following the first video (e.g., subsequent to the first video). For example, in a case in which the position difference between the position of the object included in the first video and the position of the object included in the second video following the first video is less than or equal to the first threshold value, the processor  120  may cause the position of the zoom region of the first video to be maintained (unchanged) in the second video (e.g., such that the zoom region is not moved). 
     In an embodiment, the processor  120  may track an object to be identified within the second video quickly (or sensitively) by determining the first threshold value to be lower as the region in which the first object has moved within the first video is larger. For example, in a case in which a movement of an object to be identified is present in the second video, the processor  120  may quickly move the zoom region according to the movement of the object by determining the first threshold value to be lower. 
     In an embodiment, the processor  120  may cause the zoom region of the object to be unchanged with respect to a small movement of the object to be identified within the second video by determining the second threshold value to be higher as the region in which the first object has moved within the first video is smaller. The processor  120  may obtain a stable video by causing the zoom region of the object to be unchanged with respect to a small movement of the object to be identified within the second video. 
     In an embodiment, the processor  120  may determine the movement speed of the zoom region of the second video, based on the average movement speed of the first object. For example, the processor  120  may configure the movement speed of the zoom region of the second video to be higher (e.g., faster) as the average movement speed of the first object is higher (e.g., faster), and determine the movement speed of the zoom region of the first video to be lower (e.g., slower) as the average movement speed of the first object is lower (e.g., slower). 
     In an embodiment, the processor  120  may stably or accurately track the object to be identified in the second video by determining the movement speed of the zoom region of the second video, based on the average movement speed of the first object. For example, the processor  120  may cause the zoom region of the object to be identified in the second video to move smoothly or accurately by determining the movement speed of the zoom region of the second video, based on the average movement speed of the first object. 
     In an embodiment, the processor  120  may determine a padding region (e.g., the size of a padding region) of a zoom region to be applied to the second video, based on the amount of change in the position and size of the first object. 
       FIG.  6    is a diagram  600  for explaining a padding region of a zoom region to be applied to a second video, according to various embodiments. 
     Referring to  FIG.  6   , the size of the zoom region  610  may be determined by the size of the tracking region  620  (or the size of the object) and the left distance (or left padding (PL)), the upper distance (or upper padding (PU)), the right distance (or right padding (PR)), and the lower distance (or a lower padding (PD)) from the tracking region  620 . In an embodiment, the processor  120  may determine the padding region of the zoom region to be applied to the second video to be wider as the amount of change in the position and size of the first object of the first video increases. For example, the processor  120  may determine the left padding (PL), upper padding (PU), right padding (PR), and lower padding (PD) of the zoom region to be applied to the second video to be longer as the average amount of change in the position of the first object and/or the size of the first object of the first video increases. The processor  120  may determine the padding region of the zoom region to be applied to the second video to be narrower as the amount of change in the size of the first object and/or the position of the first object of the first video decreases. In an embodiment, in a case in which a large number of movements of an object to be identified in the second video is present within a designated time period, the processor may cause the size of the zoom region to be applied to the second video to be unchanged by determining the padding region of the zoom region to be applied to the second video to be wider as the amount of change in the position and size of the first object of the first video increases. The processor  120  may minimize shaking of a video to be acquired through the zoom region to be applied to the second video by causing the size of the zoom region to be applied to the second video to be unchanged. In an embodiment, in a case in which a small number of movements of an object to be identified in the second video is present within a designated time period, the processor may acquire a video including an object of a larger size (e.g., enlarged by a larger magnification) through the zoom region to be applied to the second video by determining the padding region of the zoom region to be applied to the second video to be narrower as the amount of change in the position and size of the first object of the first video decreases. 
     In an embodiment, in a case in which a plurality of first objects are included in a first video, the processor  120  may obtain a parameter related to a zoom region of each of the plurality of first objects, based on information on movement of each of the plurality of first objects. 
     In an embodiment, in a case in which a plurality of first objects are included in a first video, the processor  120  may obtain parameters related to zoom regions of all of the plurality of first objects, based on information on movements of all of the plurality of first objects. 
     In an embodiment, in a case in which a plurality of first objects are included in a first video, the processor  120  may obtain a parameter related to a zoom region of each of the plurality of first objects, and a parameter related to a zoom region including all of the plurality of first objects, based on information on the movement of each of the plurality of first objects and the information on the movements of all of the plurality of first objects. 
     In an embodiment, in operation  407 , the processor  120  may identify a first object corresponding to a second object (hereinafter, referred to as a “second object”) included in a second video acquired through the camera module  180 . 
     In an embodiment, the processor  120  may detect the second object from the second video acquired through the camera module  180 . For example, the processor  120  may detect at least one second object from the plurality of images of the second video using a designated algorithm (e.g., a person detection algorithm or a face detection algorithm). 
     In an embodiment, the processor  120  may identify, within the first video, the first object corresponding to the second object of the second video. 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object by comparing the feature (e.g., feature points) of the second object with the feature of the first object in the first video. For example, in a case in which the similarity rate (or matching degree) between the feature of the second object and the feature of the first object in the first video is greater than or equal to a specified similarity rate, the processor  120  may identify the first object as corresponding to the second object. As another example, in a case in which the first video includes a plurality of first objects, the processor  120  may identify the first object corresponding to the second object from among the plurality of first objects by comparing the second object and the plurality of first objects. As another example, in a case in which the second video includes a plurality of second objects and the first video includes a plurality of first objects, the processor  120  may identify at least one first object, from among the plurality of first objects, corresponding to at least one second object selected based on a user input from among the plurality of second objects. 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object by comparing the position of the second object with the position of the first object. For example, the processor  120  may compare the position (e.g., coordinate) of the second object at a first time point (e.g., a time point after a first time with reference to a start time point (e.g., the capturing time point) of the second video) of the second video with the position of the first object at a time point (e.g., a time point after the first time with reference to a start time point of the first video) of the first video corresponding to the first time point of the second video. In a case in which the difference between the position of the second object at the first time point of the second video and the position of the first object at the time point corresponding to the first time point is less than a designated difference, the processor  120  may identify the first object as corresponding to the second object. 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object by comparing the amount of change in the position of the second object with the amount of change in the position of the first object. For example, the processor  120  may identify a change (e.g., displacement) of the position of the second object within a predetermined number of images in the second video. The processor  120  may identify an object, the position of which has been changed by the change in the position of the second object within images of the first video as a first object corresponding to the second object. 
     In an embodiment, in a case in which the first video includes a plurality of first objects, the processor  120  may identify the first object corresponding to the second object from among the plurality of first objects by comparing the position (or amount of change in position) of the second object with the positions (or amounts of changes in positions) of the plurality of first objects. 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object, based on the time points (or times) corresponding to the first video and the second video. 
     For example, the processor  120  may identify the second object at a first time point (e.g., a time point after a first time with reference to a start time point of the second video) of the second video. The processor  120  may identify a time point of the first video corresponding to the first time point of the second video (e.g., a time point after the first time from the start time of the first video). The processor  120  may identify an object included in an image at the time point of the first video corresponding to the first time point of the second video as the first object corresponding to the second object. 
     As another example, the processor  120  may identify, in the second video, a second object (e.g., a second object corresponding to a subject outside the range of the angle of view of the camera module  180  after being within the range of the angle of view of the camera module  180  for a first time) included in the second video for the first time. The processor  120  may identify, in the first video, an object included in the first video for the first time, as the first object corresponding to the second object. 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object, based on an audio signal. 
     In an embodiment, the processor  120  may acquire an audio signal (e.g., an audio signal related to music) (hereinafter, referred to as an “acquired audio signal”) through a microphone (e.g., the input module  150 ) while acquiring the second video through the camera module  180 . The processor  120  may identify a waveform of the acquired audio signal and/or energy of the audio signal. 
     In an embodiment, the processor  120  may identify a correlation between the acquired audio signal and the audio signal of the first video, based on the waveform of the acquired audio signal and the waveform of the audio signal of the first video. The processor  120  may identify the acquired audio signal and the audio signal of the first video as corresponding audio signals (e.g., audio signals for the same music), based on the correlation between the acquired audio signal and the audio signal of the first video. The processor  120  may identify a second time point (e.g., a second time point with reference to a time point of the first video) of the first video corresponding to a first time point (e.g., a first time point with reference to a time point of the second video) of the second video, based on the time difference (e.g., delay time or phase difference) between the waveform of the acquired audio signal and the waveform of the audio signal of the first video. 
     In an embodiment, the processor  120  may identify the energy of the acquired audio signal and the energy of the audio signal of the first video are corresponding audio signals (e.g., audio signals for the same music), based on the energy of the acquired audio signal and the energy of the audio signal of the first video. The processor  120  may identify a second time point (e.g., a second time point with reference to a time point of the first video corresponding to a first time point (e.g., a first time point with reference to a time point of the second video) of the second video, based on the time difference (e.g., delay time) between the energy of the acquired audio signal and the energy of the audio signal of the first video. 
     In an embodiment, the processor  120  may identify a first object corresponding to a second object, based on at least one among a time, a beat, a rhythm, or a tempo of the acquired audio signal. For example, the processor  120  may recognize, at a first time point of the second video, at least one of a time, a beat, a rhythm, or a tempo of the acquired audio signal. The processor  120  may identify, in the first video, a time point at which at least one of a time, a beat, a rhythm, or a tempo corresponding to at least one among a time, a beat, a rhythm, or a tempo of the acquired audio signal is recognized, as a time point corresponding to (or in sync with) the first time point of the second video. 
     In an embodiment, the processor  120  may identify a first object corresponding to a second object, based on the voice signal included in the acquired audio signal. For example, the processor  120  may recognize, at a first time point of the second video, a voice signal (e.g., a user&#39;s voice signal) included in the acquired audio signal, for example, using the voice recognition module. The processor  120  may identify, in the first video, a time point at which a voice signal corresponding to a voice signal included in the acquired audio signal is recognized, as a time point corresponding to the first time point of the second video. 
     In an embodiment, the processor  120  may identify a first object corresponding to a second object, based on noise (e.g., ambient noise or white noise) included in the acquired audio signal. For example, the processor  120  may recognize, at the first time point of the second video, the noise included in the acquired audio signal. The processor  120  may identify, in the first video, a time point at which a voice signal corresponding to noise included in the acquired audio signal is recognized, as a time point corresponding to the first time point of the second video. 
     In an embodiment, the processor  120  may identify, at the first time point of the second video and at the second time point corresponding thereto, a first object corresponding to a second object by comparing the feature (e.g., feature points) of the second object in the second video with the feature of the first object in the first video. 
     In an embodiment, the processor  120  may identify, at the first time point of the second video and at the second time point corresponding to the first time point, a first object corresponding to a second object by comparing the position (or amount of change in position) of the second object with the position (or amount of change in position) of the first object. 
     In an embodiment, the processor  120  may identify, at the first time point of the second video and at the second time point corresponding to the first time point, a first object corresponding to a second object by comparing the feature and position (or the amount of change in position) of the second object with the feature and position (or the amount of change in position) of the first object. 
     The above discussion of operation  407  identify various manners in which a first object corresponding to the second object included in the second video is identified, but the disclosure is not limited in this respect. For example, the processor  120  may identify, in the second video, the second object corresponding to the first object included in the first video. As another example, in a case in which a plurality of first objects are identified in the first video, the processor  120  may identify the second object corresponding to each of the plurality of first objects in the second video. 
     In an embodiment, in operation  409 , the processor  120  may acquire a video of the second object from the second video, based on a parameter (e.g., a default parameter related to a zoom region) related to the zoom region. For example, the processor  120  may acquire a video of the second object by cropping a plurality of images included in the second video, based on the default parameter. 
     In an embodiment, the processor  120  may apply a default parameter related to a zoom region of the first object in the first video corresponding to the second object with respect to the second object in the second video (or the plurality of images including the second object). For example, in a case in which the second object is a (2-1)th object (e.g. (2-1)th object is an object detected in the second video), the processor  120  may apply a default parameter related to the zoom region of a (1-1)th object in the first video corresponding to the (2-1)th object. For another example, in a case in which the second object is a (2-2)th object (e.g. (2-2)th object is an object detected in the second video, the (2-2)th object being different from the (1-2)th object), the processor  120  may apply a default parameter related to the zoom region of a (1-2)th object in the first video corresponding to the (2-2)th object. As another example, in a case in which the second object is a plurality of second objects, the processor  120  may apply a default parameter related to the zoom region of a plurality of first objects in the first video corresponding to the plurality of second objects. 
     In an embodiment, the processor  120  may apply a default parameter related to the zoom region of the first object in the first video corresponding to the second object with respect to the second object, for each time section of the second video, based on the second object included in the second video in the time section. For example, in a case in which the (2-1)th object is included in the images in the first time section of the second video, the processor  120  may apply a default parameter related to the zoom region of the (1-1)th object in the first video corresponding to the (2-1)th object. In another example, in a case in which the (2-2)th object is included in the images at the second time section of the second video, the processor  120  may apply a default parameter related to the zoom region of the (1-2)th object in the first video corresponding to the (2-2)th object. 
     In an embodiment, the processor  120  may apply a default parameter related to the zoom region with respect to the second video (e.g., each of a plurality of images included in the second video) while acquiring the second video. 
     In an embodiment, the processor  120  may determine, as a default parameter related to the zoom region, a threshold value (a first threshold value) related to the movement of the zoom region to be applied to the second video, movement speed of the zoom region of the second video, and/or a padding region (e.g., the size of the padding region) of the zoom region to be applied to the second video. 
     In an embodiment, while the second video is acquired, the processor  120  may acquire a video by moving, at a movement speed (e.g., an average movement speed) of the zoom region when the second object moves by a first threshold value or more, the zoom region having the size determined based on the padding region. 
     Various embodiments of an example method for applying a default parameter related to a zoom region with respect to a second video will be described in detail below with reference to  FIGS.  7  and  8   . 
       FIG.  7    is a diagram  700  for explaining an example method for applying a default parameter related to a zoom region with respect to a second video, according to various embodiments. 
     Referring to  FIG.  7   , reference numeral  710  may indicate a plurality of images  711 ,  712 , and  713  in a second video acquired through the camera module  180  over time. 
     In an embodiment, the processor  120  may apply (e.g., configure) a default parameter to the second object  721  detected from the first image  711  at a first time point (t 1 ). For example, the processor  120  may apply a padding region of the zoom region of the default parameter with respect to the second object  721  (or a tracking region of the second object  721 ) detected from the first image  711  at the first time point (t 1 ), thereby determining (e.g., configuring) a first zoom region  731 . 
     In an embodiment, the processor  120  may apply (e.g., configure) a default parameter with respect to the second object  722  detected from the second image  712  at the second time point (t 2 ). For example, the processor  120  may apply the movement speed of the zoom region of the default parameter with respect to the first zoom region  731  of the first image  711  at the first time point (t 1 ). The processor  120  may apply the padding region of the zoom region of the default parameter to the detected second object  722  (or the tracking region of the second object  722 ), thereby determining (e.g., configuring) the second zoom region  732 . In an embodiment, in a case in which the difference between the position of the first object  721  in the first image  711  at the first time point (t 1 ) and the position of the second object  722  in the second image  712  at the second time point (t 2 ) is the first threshold value or less, the processor  120  may not move the position of the first zoom region  731  to the position of the second zoom region  732  with respect to the second image  712  at the second time point (t 2 ) (e.g., the position of the zoom region  731  at the first time point (t 1 ) is maintained at the second time point (t 2 )). 
     In an embodiment, the processor  120  may apply (e.g., configure) a default parameter with respect to the second object  723  detected from the third image  713  at a third time point (t 3 ), thereby determining the third zoom region  733 . 
     In an embodiment, the processor  120  may enlarge (or reduce) the first zoom region  731 , the second zoom region  732 , and the third zoom region  733 , thereby acquiring a part of a video. The processor  120  may repeat the operation of acquiring the first zoom region  731 , the second zoom region  732 , and the third zoom region  733 , based on the method described with reference to  FIG.  7   , thereby acquiring a video. 
     In  FIG.  7   , examples of a method for applying a default parameter, based on the second object  722  detected from the second image  712  of the second video, have been described. However, in an embodiment, the processor  120  may determine (e.g., predict) the position and size of an object to be included in the second image  812  using the first video, and apply a default parameter to the determined position and size of the object. Various embodiments of a method for applying a default parameter, based on the position and size of an object to be included in the second image  812 , using the first video will be described later in detail with reference to  FIGS.  9  and  10   . 
       FIG.  8    is a diagram  800  for explaining an example method for applying a default parameter related to a zoom region with respect to a second video, according to various embodiments. 
     Referring to  FIG.  8   , reference numeral  810  may indicate a plurality of images  811 ,  812 , and  813  in a second video acquired through the camera module  180  over time. 
     In an embodiment, the processor  120  may determine (e.g., predict) the position and size of the object  822  in the second image  812  acquired at the second time point (t 2 ) after the plurality of images  813 , based on the position and size of the object  821  in the first image  811  acquired at the first time point (t 1 ) and the position and size of the object in at least one image acquired before the first image  811 . For example, the processor  120  may determine (e.g., predict) the position and size of the object  822  in the second image  812  after the plurality of images  813  using a designated method (e.g., a Kalman filter), based on the position and size of the object  821  in the first image  811  and the position and size of the object in at least one image acquired before the first image  811 . 
     In an embodiment, the processor  120  may determine (e.g., calculate) the second time point (t 2 ) (or the number of the plurality of images  813  corresponding to the second time point (t 2 )) in consideration of the speed at which images of the second video are acquired (e.g., frame per second (FPS)) and the time required to determine zoom regions for the plurality of images  813 . 
     In an embodiment, the processor  120  may determine the position and size of the zoom region to be applied to the plurality of images  813  to be acquired between the first image  811  and the second image  812  using a default parameter related to the zoom region of the first object in the first video, based on the position and size of the object  821  in the first image  811  and the position and size of the object  822  in the second image  812 . 
     In an embodiment, the processor  120  may determine the zoom region (e.g., position and size of a zoom region)  832  to be applied to the object  822 , based on the position and size of the object  822  in the second image  812 . For example, the processor  120  may determine the zoom region  832  by applying a padding region of the zoom region of the default parameter, based on the position and size of the object  822  in the second image  812 . 
     In an embodiment, the processor  120  may determine the zoom regions (hereinafter referred to as “target zoom regions”) (e.g., zoom region  833 ) to be applied to the plurality of images  813  to be acquired between the first image  811  and the second image  812 , based on the zoom region  831  of the object  821  in the first image  811  and the zoom region  832  of the object  822  in the second image  812 . 
     In an embodiment, the processor  120  may determine a parameter related to the size and movement speed of the target zoom regions using Equation 1 below. 
         k =α+β*area( B   1 )+γ*(1− IoU ( B   1   ,B   2 )+μ*distance( B   1   ,B   2 )  [Equation 1]
 
     In [Equation 1], k may denote a parameter related to the movement speed of the target zoom regions, B 1  may denote the position and size of the zoom region  831  of the first image  811 , and B 2  may denote the position and size of the zoom region  832  of the second image  812 . 
     Area (B 1 ) may denote the size (e.g., area) of the zoom region  831  of the first image  811 . Intersection of union (IoU) (B 1 , B 2 ) may denote an intersection (a value obtained by dividing an intersection by a union) with respect to the union of B 1  and B 2 . Distance (B 1 ,B 2 ) may denote a distance (e.g., the difference between the position of B 1  and the position of B 2 ) between the position of B 1  and the position of B 2 . 
     α may be a coefficient indicating the movement speed of the zoom region of the default parameter, β may be a coefficient indicating the weight for the zoom region of the (1-1)th time point (e.g., t 1  in  FIG.  10   ) of a second video, γ may be a coefficient indicating the weight for IoU (B 1 , B 2 ), and μ may be a coefficient indicating the weight for distance (B 1 , B 2 ). 
     α, β, γ, and μ may be configured such that k is between 0 and 1. 
     Based on [Equation 1], the movement speed of the target zoom regions may be proportional to the movement speed of the zoom region of the default parameter, the size (e.g., area) of the zoom region  831  of the first image  811 , and the distance between the zoom region  831  and the zoom region  832 , and may be inversely proportional to IoU (B 1 ,B 2 ) (the overlapping region between the zoom region  831  and the zoom region  832 ). 
     In an embodiment, based on [Equation 1], as the distance between the zoom region  831  and the zoom region  832  increases (e.g., as spaced farther), the movement speed of the target zoom regions may increase. Based on [Equation 1], as the distance between the zoom region  831  and the zoom region  832  increases, the speed (e.g., acceleration) at which the movement speed of the target zoom regions increases may decrease. Through this, the zoom region  833  may be moved stably (or smoothly) within the plurality of images  813 . 
     In an embodiment, at least one of the elements in [Equation 1] may not be considered when determining the parameter k related to the movement speed and size of the target zoom regions. For example, the speed at which a plurality of images of the second video are acquired (e.g., frame per second (FPS)) may be faster by a designated speed or more, compared to the movement speed (e.g., the maximum speed) of the second object in the second video. In this case, the parameter k related to the movement speed and size of the target zoom regions may be determined by excluding μ*distance (B 1 ,B 2 ) from among the elements in [Equation 1]. 
     In an embodiment, the processor  120  may determine target zoom regions (e.g., positions and sizes of target zoom regions) using Equation 2 below, based on the parameter k related to the movement speed and size of the target zoom regions. 
         B   n   =k*B   2 +(1− k )*( B   1 )  [Equation 2]
 
     B n  may denote the position and size of each of the target zoom regions (e.g., the zoom region  833  of the image  813 ), B 1  may denote the position and size of the first image  811 , B 2  may denote the position and size of the second image  812 .

     In an embodiment, the processor  120  may apply the position and size of each of the target zoom regions with respect to the plurality of images  813  while the plurality of images  813  are acquired through the camera module  180 . 
       FIG.  8    describes examples of determining (e.g., predicting) the position and size of the object  822  in the second image  812  after the plurality of images  813  using a designated method (e.g., Kalman filter). However, in an embodiment, the processor  120  may determine (e.g., predict) the position and size of the object  822  in the second image  812  using the first video. A method for determining (e.g., predicting) the position and size of the object  822  in the second image  812  using the first video will be described later in detail with reference to  FIGS.  11  and  12   . 
     In an embodiment, the processor  120  may enlarge (or reduce) target zoom regions within the plurality of images  813 , thereby acquiring a part of a video. Based on the method described with reference to  FIG.  8   , the processor  120  may repeat an operation of acquiring target zoom regions, thereby acquiring a video. 
     In an embodiment, the processor  120  may store the acquired video in the memory  130 . 
     In an embodiment, the processor  120  may display the acquired video through a display (e.g., the display module  160 ). For example, the processor  120  may continuously display enlarged images of target zoom regions in the acquired video through a display (e.g., the display module  160 ) in real time. 
     Although not shown in  FIG.  4   , in an embodiment, the processor  120  may configure a mode corresponding to a parameter related to a zoom region. For example, the processor  120  may store, in the memory  130 , parameters related to zoom regions for a plurality of videos (e.g., a first video). In an embodiment, in a case in which the processor  120  stores a parameter related to a zoom region in the memory  130 , the processor  120  may store, in the memory  130 , an image (e.g., a thumbnail) representing (or to identify) the parameter related to the zoom region together with the parameter. 
     In an embodiment, the processor  120  may configure a mode for each of parameters related to zoom regions. In a case in which a user of the electronic device  101  selects a desired mode, the processor  120  may apply a parameter related to a zoom region corresponding to the selected mode with respect to a video desired to be recorded. Through this, the user may apply, with respect to a video desired to be recorded, a parameter related to a zoom region of an object corresponding to a recorded subject, the motion of which is similar to the motion (e.g., dancing motion) of a subject desired to be recorded by the user. 
     In an embodiment, the processor  120  may apply a parameter related to a zoom region with respect to an object corresponding to a subject while displaying a preview through a display (e.g., the display module  160 ), based on the image acquired through the camera module  180 , thereby allowing the user to identify whether a parameter related to a desired zoom region has been obtained. Various embodiments related thereto will be described later in detail with reference to  FIG.  16   . 
     Although not shown in  FIGS.  4  to  9   , in an embodiment, the processor  120  may adjust the configuration of the camera module  180 , based on a parameter related to a zoom region (e.g., the camera module  180  (e.g., by controlling the lens assembly  210 )), thereby acquiring a video of a second object from the second video. For example, the processor  120  may determine whether to move the lens assembly  210 , based on a threshold value related to the movement of the zoom region. The processor  120  may determine the movement speed (e.g., the average speed) at which the lens assembly  210  is moved, based on the average movement speed of the zoom region. The processor  120  may control the lens assembly  210  to perform a zoom-in or zoom-out operation, based on a padding region of the zoom region. 
     Although not shown in  FIGS.  4  to  9   , in an embodiment, the processor  120  may move the electronic device, based on a parameter related to a zoom region. For example, in a case in which the electronic device  101  (e.g., an electronic device implemented in the form of a robot) includes a driving unit (e.g., a motor) capable of moving the position of the electronic device  101  or changing the direction in which the electronic device  101  (e.g., the camera module  180 ) faces, the processor  120  may move the electronic device  101  by controlling the driving unit, based on the parameter related to the zoom region. As another example, in a case in which the electronic device  101  is mounted on an external electronic device (e.g., a gimbal) capable of moving the electronic device  101 , the processor  120  may transmit a signal for moving the electronic device  101  to the external electronic device, based on the parameter related to the zoom region through the communication module  190 . 
       FIG.  9    is a flowchart  900  for explaining an example method for applying a parameter related to a zoom region to be applied to a second video using a first video, according to various embodiments. 
       FIG.  10    is a diagram  1000  for explaining an example method for applying a parameter related to a zoom region to be applied to a second video using a first video, according to various embodiments. 
     Referring to  FIGS.  9  and  10   , in operation  901 , according to an example embodiment, the processor  120  may identify a (1-1)th time point of the first video corresponding to a (2-1)th time point of the second video (e.g., the current time point of the second video). For example, in  FIG.  10   , the processor  120  may identify a (1-1)th time point (t 1 ) of the first video corresponding to a (2-1)th time point (t 3 ) of the second video. The operation of identifying the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video may be understood as an operation of synchronizing the second video and the first video. 
     In an embodiment, the processor  120  may compare the position (or change in position) of the second object at the (2-1)th time point of the second video with the positions (or change in positions) of the first objects in the first video, thereby identifying the (1-1)th time point corresponding to the (2-1)th time point. 
     In an embodiment, the processor  120  may identify the position (or change in position) of the second object  1023  included in the image  1023  at the (2-1)th time point of the second video. The processor  120  may identify, from among the plurality of images in the first video, the first object  1013  included in the image  1011  in the first video corresponding to the position of the second object  1023  at the (2-1)th time point of the second video. For example, the processor  120  may identify a change (e.g., displacement) in the position of the first object included in the designated number of images before the image  1023 . The processor  120  may determine the (1-1)th time point (t 1 ) of the image  1013  including the second object, the position of which has changed (e.g., has moved) in the first video to correspond to the change in the position of the first object (e.g., be similar to the change in the position of the first object). However, the disclosure is not limited in this respect, and the processor  120  may identify a time point (e.g., a time point after the first time as the start time point of the first video) based on the start time point of the first video, corresponding to the (2-1)th time point (t 3 ) (e.g., a time point after the first time from the start time point (e.g., the capturing time point) of the second video) of the second video based on the start time point (e.g., the capturing time point) of the second video. In a case in which the position of the second object at the (2-1)th time point corresponds to the position of the first object at the time point of the first video based on the start time point of the first video, the processor  120  may determine, as the (1-1)th time point (t 1 ), a time point based on the start time point of the first video. 
     In an embodiment, the processor  120  may identify a (1-1)th time point corresponding to a (2-1)th time point, based on a time of the second video and a time of the first video. For example, the processor  120  may determine, as the (1-1)th time point (t 1 ), a time point (e.g., a time point after a first time as the start time point of the first video) based on the start time point of the first video, corresponding to the (2-1)th time point (t 3 ) (e.g., a time point after the first time from the start time point (e.g., the capturing time point) of the second video) of the second video based on the start time point (e.g., the capturing time point) of the second video. 
     In an embodiment, the processor  120  may identify a (1-1)th time point corresponding to a (2-1)th time point, based on an audio signal. 
     In an embodiment, while the second video is acquired through the camera module  180 , the processor  120  may acquire an audio signal (e.g., an audio signal related to music) through a microphone (e.g., the input module  150 ). The processor  120  may identify a waveform of the acquired audio signal and/or energy of the audio signal. 
     In an embodiment, the processor  120  may identify correlation between the acquired audio signal and the audio signal of the first video, based on the waveform of the acquired audio signal and the waveform of the audio signal of the first video. The processor  120  may identify a waveform of the audio signal acquired for a designated time point before the (2-1)th time point and a time section of the first video having a high correlation (e.g., having a correlation greater than or equal to a designated value). The processor  120  may determine the last time point of the time section of the first video as the (1-1)th time point (t 1 ) corresponding to the (2-1)th time point (t 3 ). 
     In an embodiment, the processor  120  may identify energy of the acquired audio signal and energy of the audio signal of the first video as corresponding audio signals (e.g., an audio signal for the same music), based on the energy of the acquired audio signal and the energy of the audio signal of the first video. The processor  120  may identify a time section of the first video in which energy of an audio signal of the first video is acquired, the energy having the difference of a designated value or less with respect to the energy of the audio signal acquired in the time section before the (2-1)th time point. The processor  120  may determine the last time point of the time section of the first video as the (1-1)th time point (t 1 ) corresponding to the (2-1)th time point (t 3 ). 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object, based on at least one of a time, a beat, a rhythm, and a tempo of the acquired audio signal. For example, the processor  120  may recognize at least one of a time, a beat, a rhythm, and a tempo of the acquired audio signal at the (2-1)th time point of the second video. The processor  120  may identify a time point at which at least one of a time, a beat, a rhythm, or a tempo corresponding to at least one of a time, a beat, a rhythm, and a tempo of the audio signal acquired in the first video is recognized as the (1-1)th time point of the first video corresponding to (or in sync with) the (2-1)th time point of the second video. 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object, based on the voice signal included in the acquired audio signal. For example, the processor  120  may recognize a voice signal (e.g., a user&#39;s voice signal) included in the acquired audio signal at the (2-1)th time point of the second video, for example, using a voice recognition module. The processor  120  may identify, as the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video, a time point at which a voice signal corresponding to the voice signal included in the audio signal acquired in the first video is recognized. 
     In an embodiment, the processor  120  may identify the first object corresponding to the second object, based on noise (e.g., ambient noise or white noise) included in the acquired audio signal. For example, the processor  120  may recognize the noise included in the acquired audio signal at the (2-1)th time point of the second video. The processor  120  may identify, as a (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video, a time point at which a voice signal corresponding to noise included in the audio signal acquired in the first video is recognized. 
     In operation  903 , according to an embodiment, the processor  120  may determine the position and size of the first object in a next image of the image at the (1-1)th time point of the first video. For example, in  FIG.  10   , the processor  120  may determine the position and size of the first object  1014  of the image  1012  as the next image (e.g., a next image frame) of the image  1011 . 
     Operation  903  and  FIG.  10    show that the position and size of the first object  1014  included in the image  1012  as the next image (e.g., the next image frame) of the image  1011  are determined, but the disclosure is not limited in this respect. 
     In an embodiment, the processor  120  may determine the position and size of the first object in the image at the (1-2)th time point as a time point following the (1-1)th time point (t 1 ). In an embodiment, the processor  120  may determine the (1-2)th time point of the first video in consideration of the frame rate of the first video and the frame rate of the second video. 
     In operation  905 , in an embodiment, the processor  120  may predict the position and size of an object corresponding to the position and size of the first object in the next image (e.g., the image  1012 ) within the image to be acquired in the second video to correspond to the next image (e.g., the image  1012 ) of the first video. 
     For example, the processor  120  may determine the position and size (e.g., the position and size of the object  1024  predicted to be included in the image  1022  at the (2-2)th time point (t 4 )) of the object  1024  to be included in the image  1022  at the (2-2)th time point (t 4 ) of the second video corresponding to the (1-2)th time point (t 2 ) of the first video, based on the position and size of the first object  1014  in the image  1012 . The processor  120  may determine the (2-2)th time point (t 4 ) of the second video by adding the difference between the (1-2)th time point (t 2 ) and the (1-2)th time point (t 1 ) to the (2-1)th time point (e.g., the current time point) of the second video. 
     In operation  907 , in an embodiment, the processor  120  may determine a zoom region, based on the determined position and size of an object. For example, the processor  120  may determine a zoom region of the determined object  1024  (e.g., the determined position and size of the object  1024 ) using a parameter related to the zoom region (e.g., a default parameter related to the zoom region). 
     In operation  909 , according to an embodiment, the processor  120  may apply the determined zoom region with respect to an image following the image acquired at the (2-1)th time point of the second video. For example, the processor  120  may apply the determined zoom region with respect to the second object included in the next image (acquired through the camera module  180  (or stored in the memory  130  after being acquired through the camera module  180 ) after the (2-1)th time point (t 3 )) of the image  1021  of the second video. 
     In an embodiment, the processor  120  may acquire a video by repeatedly performing operations  901  to  909 . 
     In an embodiment, the processor  120  may acquire a video by repeatedly performing operations  903  to  909 , except for operation  901 , after performing operations  901  to  909 . For example, in a case in which the frame rate of the first video and the frame rate of the second video are the same, the processor  120  may perform operation  901  such that the time point of the first video and the time point of the second video are synchronized, and accordingly, operation  901  may not need to be performed again in the subsequent operations. 
     In an embodiment, although not shown in  FIG.  9   , in a case in which the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video (e.g., the current time point of the second video) cannot be identified in operation  901 , the processor  120  may acquire a video, based on the method described with reference to  FIG.  7    or  FIG.  8   . For example, after the time point of the first video and the time point of the second video are synchronized, the subject corresponding to the second object in the second video may move differently from the subject corresponding to the first object in the first video for a designated time (e.g., in a case in which the subject corresponding to the second object dances differently from the subject corresponding to the first object). In a case in which the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video (e.g., the current time point of the second video) cannot be identified for a designated time or the position (and size) of the second object in the second video is identified as being changed differently from the position (and size) of the first object in the first video for the designated time, the processor  120  may acquire a video by applying a default parameter related to a zoom region with respect to the second video in the method described with reference to  FIG.  7    or  FIG.  8   . 
       FIG.  11    is a flowchart  1100  for explaining an example method for applying a parameter related to a zoom region to be applied to a second video using a first video, according to various embodiments. 
       FIG.  12    is a diagram  1200  for explaining an example method for applying a parameter related to a zoom region to be applied to a second video using a first video, according to various embodiments. 
     Referring to  FIGS.  11  and  12   , in an embodiment, the processor  120  may identify the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video (e.g., the current time point of the second video) in operation  1101 . For example, in  FIG.  12   , the processor  120  may identify the (1-1)th time point (t 1 ) of the first video corresponding to the (2-1)th time point (t 3 ) of the second video. 
     Since the operation  1101  of identifying the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video is at least partially the same as or similar to operation  901  of  FIG.  9   , a detailed description thereof will not be repeated. 
     According to an embodiment, the processor  120  may determine the position and size of the first object included in the image at the (1-2)th time point following the (1-1)th time point of the first video in operation  1103 . For example, in  FIG.  12   , the processor  120  may determine the position and size of the first object  1242  included in the image  1212  at the (1-2)th time point (t 2 ) as the next time point after the (1-1)th time point (t 1 ). 
     According to an embodiment, the (1-2)the time point t 2  of the first video may be a time point in consideration of the frame rate of the first video and the frame rate of the second video from the (1-1)th time point (t 1 ) of the first video (e.g., the time point at which the image  1211  is acquired), the time required to detect the second object in each of the plurality of images in the second video, and the time required to determine (e.g., predict) a zoom region in operation  1109 , which will be described later. 
     In an embodiment, in operation  1105 , the processor  120  may determine (e.g., predict) the position and size of the object corresponding to the position and size of the first object at the (1-2)th time point, within the image at the (2-1)th time point of the second video corresponding to the (1-2)th time point of the first video. 
     In an embodiment, the processor  120  may determine the position and size of the object  1243 , which is predicted to be included in the image  1222  at the (2-2)th time point (t 4 ) of the second video corresponding to the (1-2)th time point of the first video, based on the position and size of the first object  1242  included in the image  1212  at the (1-2)th time point of the first video. The processor  120  may determine the (2-2)th time point (t 4 ) of the second video by adding the difference between the (1-2)th time point (t 2 ) and the (1-2)th time point (t 1 ) to the (2-1)th time point (e.g., the current time point) of the second video. 
     In an embodiment, the processor  120  may determine the zoom region corresponding to the determined position and size of the object in operation  1107 . For example, the processor  120  may determine the zoom region  1233  (e.g., the position and size of the zoom region  1233 ) of the determined object  1243  (e.g., the determined position and size of the object  1243 ) using the parameter related to the zoom region (e.g., the default parameter related to the zoom region). 
     In one embodiment, the processor  120  may determine the size of the zoom region  1233  of the (2-2)th time point in consideration of the sizes of the first object included in the plurality of images acquired during a time period from a time point before the first time with reference to the (1-1)th time point (t 1 ) of the first video to a time point after the second time with reference to the (1-1)th time point (t 1 ) of the first video. For example, the processor  120  may apply a padding region of the default parameter with respect to the region (e.g., the region including the first object) (or the region of the second object obtained by matching (mapping) the region of the first object of the largest size to the second video, based on the ratio between the first video and the second video area of the object) of the first object of the largest size among the sizes of the first object included in the plurality of images, thereby determining (e.g., adjusting) the size of the zoom region  1233  of the (2-2)th time point. In this case, the size of the target zoom regions to be described later in operation  1109  may be determined to be larger (or more spacious) than the size of the target zoom regions to which only the padding region of the default parameter is applied, and a video with less shaking may be obtained from the second video. 
     In an embodiment, the processor  120  may determine, in operation  1109 , a zoom region to be applied to a plurality of images to be acquired between the (2-1)th time point and the (2-2)th time point, based on the determined zoom region and the zoom region of the image at the (2-1)th time point of the second video. 
     In an embodiment, the processor  120  may determine the zoom region  1231  of the second object  1241  included in the image  1221  at the (2-1)th time point. The processor  120  may acquire a parameter related to a plurality of zoom regions (hereinafter, “target zoom regions”) to be applied to a plurality of images (e.g., the image  1223 ) to be acquired at a time between the (2-1)th time point and the (2-2)th time point), based on the zoom region  1231  and the determined zoom region  1233  at the (2-2)th time point. 
     In an embodiment, the processor  120  may determine parameters related to the movement speed and size of the target zoom regions using Equation 1 described with reference to  FIG.  8   . For example, in a case in which [Equation 1] is applied to the embodiment of  FIG.  12   , in [Equation 1], B 1  may denote the position and size of the zoom region  1231  of the image  1221 , and B 2  may denote the position and size of the zoom region  1233 . With respect to [Equation 1] applied to the embodiment of  FIG.  12   , in order to avoid overlap with the description of  FIG.  8   , a detailed description thereof will not be repeated. 
     In an embodiment, the processor  120  may determine target zoom regions (e.g., the position and sizes of target zoom regions) using [Equation 2] described with reference to  FIG.  8   . In a case in which [Equation 2] is applied to the embodiment of  FIG.  12   , in [Equation 2], B 1  may denote the position and size of the zoom region  1231  of the image  1221 , and B 2  may denote the position and size of the zoom region  1233  of the image  1223 . With respect to [Equation 2] applied to the embodiment of  FIG.  12   , in order to avoid overlap with the description of  FIG.  8   , a detailed description thereof will not be repeated. 
     In an embodiment, the processor  120  may acquire a third video from the second video, based on the zoom region (e.g., target zoom regions) in operation  1111 . For example, while a plurality of images (e.g., the image  1223 ) are acquired through the camera module  180 , the processor  120  may acquire the third video by applying the position and size of each of the target zoom regions (e.g., a zoom region  1235 ) with respect to the plurality of images. For example, the processor  120  may acquire the third video by performing cropping on each of the plurality of images included in the second video, based on the positions and sizes of target zoom regions. 
       FIG.  11    describes that after the position and size of the object corresponding to the position and size of the first object at the (1-1)th time point are determined in the image at the (2-1)th time point of the second video, a zoom region corresponding to the determined position and size of the object is determined, but the disclosure is not limited in this respect. For example, the processor  120  may also determine a zoom region of the first object, based on the position and size of the first object at the (1-2)th time point of the first video and then determine a zoom region at the (2-2)th time point of the second video corresponding to the zoom region of the determined first object. 
       FIG.  13    is a flowchart  1300  for explaining an example method for applying a parameter related to a zoom region to be applied to a second video using a first video, according to various embodiments. 
       FIG.  14    is a diagram  1400  for explaining an example method for applying a parameter related to a zoom region to be applied to a second video using a first video, according to various embodiments. 
     Referring to  FIGS.  13  and  14   , in an embodiment, the processor  120  may identify the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video (e.g., the current time point of the second video) in operation  1301 . For example, in  FIG.  14   , the processor  120  may identify the (1-1)th time point (t 1 ) of the first video corresponding to the (2-1)th time point (t 3 ) of the second video. 
     Since the operation  1301  of identifying the (1-1)th time point of the first video corresponding to the (2-1)th time point of the second video is at least partially the same as or similar to operation  901  of  FIG.  9    and operation  1201  of  FIG.  12   , a detailed description thereof will not be repeated. 
     According to an embodiment, the processor  120  may determine the position and size of the first object included in the image at the (1-2)th time point following the (1-1)th time point of the first video in operation  1303 . For example, in  FIG.  14   , the processor  120  may determine the position and size of the first object  1442  included in the image  1412  at the (1-2)th time point (t 2 ) as a time point following the (1-1)th time point (t 1 ) (e.g., the time point at which the image  1411  is acquired). 
     In an embodiment, in operation  1305 , the processor  120  may determine (e.g., predict) the position and size of an object corresponding to the position and size of the first object at the (1-2)th time point within the image at the (2-1)th time point of the second video corresponding to the (1-2)th time point of the first video. 
     In an embodiment, the processor  120  may determine the position and size of the object  1443 , which is predicted to be included in the image  1422  at the (2-2)th time point (t 4 ) of the second video corresponding to the (1-2)th time point of the first video, based on the position and size of the first object  1442  included in the image  1412  at the (1-2)th time point of the first video. The processor  120  may determine the (2-2)th time point (t 4 ) by adding the difference between the (1-2)th time point (t 2 ) and the (1-2)th time point (t 1 ) to the (2-1)th time point (e.g., the current time point) of the second video. 
     In an embodiment, the processor  120  may determine a parameter related to the zoom region, in operation  1307 , based on the difference between the position and size of the second object at the (2-1)th time point and the determined position and size of the object. 
     In an embodiment, the processor  120  may determine the position and size of the second object  1441  included in the image  1421  at the (2-1)th time point of the second video. The processor  120  may adjust the movement speed of a zoom region of a parameter (e.g., a default parameter) related to the zoom region such that the greater the difference between the position of the second object  1441  and the position of the object  1443  is, the greater (e.g., faster) the movement speed of the zoom region is. The processor  120  may adjust the movement speed of a zoom region of a parameter (e.g., a default parameter) related to the zoom region such that the smaller the difference between the position of the second object  1441  and the position of the object  1443  is, the smaller (e.g., slower) the movement speed of the zoom region is. The processor  120  may consider the size of the second object  1441  and the size of the object  1443  when adjusting a movement speed of the zoom region of a parameter (e.g., a default parameter) related to the zoom region. 
     In an embodiment, the processor  120  may acquire a third video from the second video in operation  1309 , based on a parameter related to a zoom region. 
     In an embodiment, the processor  120  may apply the parameter related to the zoom region determined in operation  1307  with respect to images to be acquired from the (2-1)th time point (t 3 ) to the (2-2)th time point (t 4 ). 
     In an embodiment, the processor  120  may apply a parameter related to the zoom region to which a default parameter is adjusted, with respect to the images to be acquired from the (2-1)th time point (t 3 ) to the (2-2)th time point (t 4 ), thereby acquiring a third video from the second video. 
       FIG.  15    is a flowchart  1500  illustrating an example method for acquiring a first video by selecting a first video from among a plurality of videos, according to various embodiments. 
     Referring to  FIG.  15   , in an embodiment, in operation  1501 , the processor  120  may identify whether an input for automatically selecting a first video (e.g., in a designated manner) is received. The input for automatically selecting the first video may include, for example, an input through a user interface (e.g., checkbox) for receiving a user input for automatically selecting the first video or setting information (e.g., flag type information) for automatically selecting the first video. For example, the processor  120  may receive the user input through a user interface included in the camera application before the start of capturing an image or receive the user information through preconfigured setting information. 
     In an embodiment, in a case in which an input for automatically selecting the first video is received in operation  1501 , the processor  120  may analyze a video acquired (e.g., being acquired) through the camera module  180  in operation  1503 . 
     In an embodiment, in a case in which an input for automatically selecting the first video is received, the processor  120  may display a preview through a display (e.g., the display module  160 ), based on the plurality of images acquired through the camera module  180 . In an embodiment, the processor  120  may analyze the screen composition and/or background of the preview obtained through the camera module  180 . In an embodiment, the processor  120  may analyze at least one object included in the preview obtained through the camera module  180 . 
     In an embodiment, the processor  120  may select, as a first video, a video corresponding to the video analyzed in operation  1503  from among the plurality of videos stored in the memory  130  in operation  1505 . For example, the processor  120  may analyze the background and/or screen composition of the images for a designated time period from the starting point with respect to each of the plurality of videos stored in the memory  130 . The processor  120  may select, as a first video, an image having a background and/or screen composition similar to the background and/or screen composition of the video (e.g., a preview) analyzed in operation  1503 , from among the plurality of videos stored in the memory  130 . As another example, the processor  120  may analyze an object included in the images for a designated time period from the starting point with respect to each of the plurality of videos stored in the memory  130 . The processor  120  may select, as a first video, a video including an object similar to an object of the video (e.g., a preview) analyzed in operation  1503 , from among the plurality of videos stored in the memory  130 . However, the method for automatically selecting the first video from among the plurality of videos stored in the memory  130  is not limited to the above-described examples. 
     In an embodiment, in a case in which an input for automatically selecting the first video is not received in operation  1501 , the processor  120  may select one video among a plurality of videos as the first video, based on a user input in operation  1507 . For example, the processor  120  may receive a user input for selecting one video from among a plurality of videos. The processor  120  may determine the selected video as the first video, based on the user input. 
       FIG.  16    is a flowchart  1600  illustrating an example method for applying a parameter related to a zoom region with respect to an object corresponding to a subject while a preview is displayed, according to various embodiments. 
     In one embodiment,  FIG.  16    may relate to a method including, after acquiring a parameter related to a zoom region (e.g., a default parameter) (e.g., after performing operation  403  of  FIG.  4   ), applying the parameter related to the acquired zoom region to a preview to enable a user to identify whether the parameter related to the zoom region desired by the user is acquired. 
     Referring to  FIG.  16   , in an embodiment, the processor  120  may determine a parameter (e.g., a default parameter) related to a zoom region in operation  1601 . 
     In an embodiment, in operation  1603 , the processor  120  may display an indication indicating a zoom region while displaying a preview through a display (e.g., the display module  160 ), based on the plurality of images acquired through the camera module  180 . 
     In an embodiment, in a case in which an object is detected while displaying a preview, the processor  120  may apply a default parameter with respect to the detected object. While applying the default parameter with respect to the detected object, the processor  120  may display an indication indicating the boundary (e.g., four rectangle lines in case that the zoom region has a rectangle shape). 
     In an embodiment, the user may identify whether a parameter related to the zoom region desired by the user has been obtained, through movement and size change of an indication indicating the boundary of the zoom region in the preview to which a default parameter is applied. In an embodiment, in a case in which the parameter related to the zoom region desired by the user is not obtained, the processor  120  may obtain a parameter related to the zoom region desired by the user by adjusting the parameter related to the zoom region, based on a user input. 
     In an embodiment, the processor  120  may differently configure the display of the preview video and/or the indication indicating a zoom region, based on the state of the electronic device  101 . For example, the electronic device  101  may be a foldable electronic device or an extendable (or rollable, slidable) electronic device. For example, in a case in which the electronic device  101  is a foldable electronic device, the screen display region may be reduced in the folded state of the electronic device  101 . The processor  120  may detect the state of the electronic device  101  through at least one sensor (e.g., a hall sensor), and may adjust the size of a preview video, based on the size of the screen display region, in a case in which the electronic device  101  is folded. The processor  101  may display an indication indicating a zoom region on the adjusted preview screen. As another example, in a case in which the electronic device  101  is folded, the processor  120  may adjust (e.g., crop) a preview video, based on a zoom region. For example, the processor  120  may adjust the preview video such that the zoom region indication is maximally included in the preview video. For example, the processor  120  may adjust the preview video such that only a space (e.g., 10 px) of top/bottom or left/right of the region other than the zoom region, which has a designated size, is included in the preview video. In this case, the zoom region may be displayed in the center region of the display region.
