Abstract
A fingerprint sensing device includes a sensing circuit configured to extract sensing data from nodes included in each of sampling regions of a sensor array. The fingerprint sensing device also includes a control circuit configured to calculate a number of the nodes based on the extracted sensing data to produce sensing data distributions for each of the sampling regions and compare the sensing data distributions with reference distributions, configured to determine that the sampling regions from which the sensing data distributions corresponding to the reference distributions are extracted are effective contact regions, and configured to generate fingerprint information from the sensor array when the number of effective contact regions is greater than or equal to a threshold.
