controlling the camera to perform focusing of a lens included in the camera on the one or more objects and to lock the focusing of the lens; identifying a designated event for slow motion recording; based at least in part on the designated event, obtaining a plurality of second images as per a second frame rate higher than the first frame rate using the camera focusing-locked; and providing a video related to the one or more objects using at least one of the plurality of second images. ### Claim 12 (depends on 11) The method of claim 11, further comprising providing at least one image frame of the plurality of first images as a preview through the display. ### Claim 13 (depends on 11) The method of claim 11, wherein obtaining the plurality of first images as per the first frame rate using the camera is triggered based on an input to start recording video from the user. ### Claim 14 (depends on 11) The method of claim 11, wherein identifying the designated event for slow motion recording comprises identifying a user input related to initiating slow motion recording. ### Claim 15 (depends on 11) The method of claim 11, wherein identifying the designated event for slow motion recording comprises identifying a movement of the one or more objects. ### Claim 16 (depends on 11) The method of claim 11, wherein providing the video related to the one or more objects comprises providing the video related to the one or more objects by merging the at least one of the plurality of second images and at least one of the plurality of first images. ### Claim 17 (depends on 11) The method of claim 11, further comprising: identifying a movement of the electronic device, as part of identifying the designated event for slow motion recording; based on identifying the movement of the electronic device being less than the threshold, obtaining a plurality of third images as per a third frame rate through an image sensor included in the camera; identifying a movement of an object in a designated region of at least one of the plurality of third images; and based on identifying the movement of the object in the designated region of the at least one of the plurality of third images, obtaining the plurality of second images as per the second frame rate using the camera. ### Claim 18 (depends on 17) The method of claim 17, wherein identifying the movement of the object in the designated region of the at least one of the plurality of third images comprises identifying the object moving from outside the designated region to the inside of the designated region or identifying the object moving out of the designated region. ### Claim 19 (depends on 17) The method of claim 17, wherein obtaining the plurality of third images comprises obtaining the plurality of third images as per the third frame rate higher than the first frame rate. ### Claim 20 A non-transitory computer readable storage medium storing instructions configured to, when executed by a processor of an electronic device, cause the electronic device to: obtain a plurality of first images for one or more objects as per a first frame rate using a camera, control the camera to perform focusing of a lens included in the camera on at least one of one or more objects, control the camera to lock the focusing of the lens, identify a designated event for slow motion recording, based at least in part on the designated event, obtain a plurality of second images as per a second frame rate higher than the first frame rate using the camera focusing-locked, and provide a video related to the one or more objects using at least one of the plurality of second images.
