Fingerprint sensing apparatus and method having three-dimensional sensing mechanism
A fingerprint sensing apparatus having a three-dimensional (3-D) sensing mechanism that includes optical fingerprint sensing circuits and a processing circuit is provided. The optical fingerprint sensing circuits are configured to perform sensing within sensing areas to obtain sensed images, wherein each of the sensing areas corresponds to one of the optical fingerprint sensing circuits and the sensing areas includes at least one overlapped area. The processing circuit is electrically coupled to the optical fingerprint sensing circuits to receive the sensed images and generate a three-dimensional sensed image having depth information of the overlapped area according to a disparity between the sensed images.
