Beschreibung
Zusammenfassung:	An electronic circuit adapted to process fingerprint data from a panel is provided. The panel includes touch sensors and fingerprint sensors. The electronic circuit includes a fingerprint sensing circuit. The fingerprint sensing circuit is configured to receive fingerprint sensing signals corresponding to a fingerprint image from the fingerprint sensors via fingerprint sensing lines. The fingerprint sensing circuit is further configured to: select a subset of the fingerprint sensing lines to form a fingerprint sensing zone having at least one boundary and adapted for a fingerprint sensing operation based on a fingerprint touch area, wherein the subset of fingerprint sensing lines is selected based on the at least one boundary of the fingerprint sensing zone, and generate the fingerprint image according to the fingerprint sensing signals by a remapping operation.
