Abstract

An electronic device includes: a display unit which displays an image; a fingerprint sensing unit that senses a fingerprint including a ridge and a valley and outputs a fingerprint sensing signal including a fingerprint image, a readout circuit which generates a fingerprint processing signal based on the fingerprint sensing signal and determines whether the fingerprint processing signal matches a stored fingerprint signal, by comparing the fingerprint processing signal with the stored fingerprint signal, and a memory connected to the readout circuit. The readout circuit includes an area division unit, an estimation unit, a first sharpening processing unit, a second sharpening processing unit, and a processing unit.
