Abstract: Disclosed is an electronic device for selectively generating video using image data acquired at a frame rate changed according to the distance between a subject and a reference region; and an operation method. The electronic device includes a camera, memory, display and processor, which may be configured to acquire, at a first frame rate, a plurality of first images including an object of interest, identify the distance between a reference region, by using at least some first images of the plurality of first images; obtain, at a second frame rate higher than the first frame rate, a plurality of second images including the object of interest, based on the distance satisfying a first designated condition; identify whether the position of the object of interest at least temporarily belongs to the reference region, and generate video corresponding to the second frame rate for the object of interest.
