1. An electronic device comprising:
a display;
an image sensor configured to acquire an image;
a processor configured to be operatively connected to the display and the image sensor; and
a memory configured to be operatively connected to the processor,
wherein the memory is further configured to store instructions that, when executed, cause the processor to:
control the image sensor to acquire a first image at a first frame rate,
detect whether a super-slow recording function is activated,
in response to the super-slow recording function being activated, control the display to display a visual indicator corresponding to a motion detection area on a preview screen, wherein the motion detection area is a partial area of the preview screen, corresponds to a predesignated position of the preview screen, and has a predesignated size,
determine whether a motion is detected within the motion detection area based on whether an image of the motion detection area is changed,
in response to detecting the motion within the motion detection area, control the image sensor to acquire a second image at a second frame rate faster than the first frame rate,
track a moving path of an object,
calculate an expected moving path for a time for which super-slow recording is available again based on a tracking result, and
move the motion detection area along with the expected moving path.
