发明名称 AIR/OBJECT DETERMINATION FOR BIOMETRIC SENSORS
摘要 A fingerprint sensing apparatus may include a fingerprint sensor system and a control system capable of receiving fingerprint sensor data from the fingerprint sensor system. The control system may be capable of determining fingerprint sensor data blocks for at least a portion of the fingerprint sensor data and of calculating statistical variance values for fingerprint sensor data corresponding to each of the fingerprint sensor data blocks. The control system may be capable of determining, based at least in part the statistical variance values, whether an object is positioned proximate a portion of the fingerprint sensor system.

主权项 1. A fingerprint sensing apparatus, comprising: a fingerprint sensor system; and a control system capable of: receiving fingerprint sensor data from the fingerprint sensor system;determining fingerprint sensor data blocks for at least a portion of the fingerprint sensor data;calculating characteristics of variability for fingerprint sensor data corresponding to each of the fingerprint sensor data blocks; anddetermining, according to the characteristics of variability, whether an object is positioned proximate a portion of the fingerprint sensor system.
