1. An electronic circuit, adapted to process fingerprint data from a panel comprising touch sensors and fingerprint sensors, the electronic circuit comprising:
a fingerprint sensing circuit, 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, wherein the remapping operation comprises rearranging a first part of the fingerprint image obtained from the fingerprint sensing zone and a second part of the fingerprint image obtained from the fingerprint sensing zone.
