Document Type and Number:
WIPO Patent Application WO/2022/011972
Kind Code:
A1
Abstract:
A fingerprint sensing module and a fingerprint sensing method. The fingerprint sensing module comprises a light source (130), a fingerprint sensor (120) and a processing module (110). The fingerprint sensor (120) senses a finger illuminated by the light source (130) and a finger not illuminated by the light source (130), so as to obtain a first image and a second image. The processing module (110) is coupled to the fingerprint sensor (120).
