Abstract:
An electronic device includes a display, a fingerprint sensor positioned under a specified area of the display, and a processor. The processor is configured to obtain a first image based on a first input, perform authentication associated with biometric information, when a state of the first image meets a first condition, obtain a second image using the fingerprint sensor, when the state of the first image meets a second condition, adjust a setting of the fingerprint sensor, obtain a third image using the fingerprint sensor adjusted from the first value to a second value, and perform authentication associated with the biometric information based on the second image and the third image.
