Abstract: Disclosed is an electronic device. The electronic device according to an embodiment may include an ultrasonic sensor and a processor electrically connected to the ultrasonic sensor. The processor may be configured to obtain a noise signal at a periphery of the electronic device, via the ultrasonic sensor, to determine an attribute of a first ultrasonic signal oscillated by the ultrasonic sensor, based on the obtained noise signal, and to obtain fingerprint information based on the second ultrasonic signal obtained via the ultrasonic sensor and the determined attribute. Moreover, various embodiment found through the disclosure are possible.

Abstract: An electronic device is provided. The electronic device includes a transparent member, a display positioned under a transparent member that includes a plurality of pixels, an image sensor positioned under some areas of the display, a memory, and a processor. The processor obtains a first image at least based on light output through at least some of the plurality of pixels and reflected by an external object coming into contact with the transparent member using the image sensor, performs authentication on the external object at least based on the at least one template using the first image, generates a second image of the external object at least based on the first image when quality of the first image corresponds to a given condition based on a result of the authentication, and performs authentication on the external object at least based on the at least one template using the second image.

Abstract: An electronic device is provided. The electronic device includes a display including a touch sensor and a display panel, a fingerprint sensor included in the display or disposed on a rear surface of the display, and at least one processor electrically connected with the display and the fingerprint sensor. The at least one processor controls an operation of the touch sensor or lowers a frequency of an operating signal of the touch sensor in response to a specified event, activates the fingerprint sensor, and captures a fingerprint image from the fingerprint sensor.
