An electronic device according to an embodiment disclosed in the present document may comprise a camera, a display, a processor and a memory in which instructions are stored. The instructions, when executed by the processor, cause the electronic device to: identify movement of an animal included in a preview image acquired using the camera while the preview image is displayed on the display; acquire an image including the animal using a first exposure value through the camera based on determining the magnitude of the identified movement is greater than a threshold value; and acquire the image including the animal using a second exposure value that is greater than the first exposure value through the camera based on determining the magnitude of the identified movement is less than the threshold value. Other various embodiments identified through the present document are possible.
