Abstract: A method of determining a focal length and an electronic device that performs the method are provided. The electronic device includes a processor, a camera comprising a lens, and a memory configured to store one or more instructions executable by the processor. The processor is configured to receive a plurality of original images with the lens in response to the one or more instructions being executed, generate a composite image based on the plurality of original images, and determine a focal length of the lens by inputting one or more original images of the plurality of original images and the composite image to an autofocus (AF) model.
