Abstract: The electronic device according to an embodiment may include a display module, a UDC module, and a processor. The processor may operate to identify an operation mode of the UDC module. The processor may operate to change, when the operation mode is a first designated operation mode, transmittance of a UDC area in a display area of the display module, control the UDC module to configure a first path facing the sensor module, and obtain a first image based on light transferred to the sensor module. The processor may operate to change, when the operation mode is a second designated operation mode, the transmittance of the UDC area, control the UDC module to configure a second path facing the camera module, and obtain a second image based on light transferred to the camera module through the second path.

Abstract: Certain embodiments provide a biometric recognition apparatus and a method for lowering false recognition rate of biometric information in an electronic device adopting biometric recognition technology. In doing so, the electronic device may store first feature values extracted at M-ary feature points from owner biometric information, and additionally store auxiliary biometric information from a biometric information stored in one or more memories or an external server. The electronic device may perform biometric recognition on input biometric information using the first feature values and second feature values extracted from the biometric information additionally stored.
