Abstract

A fingerprint sensing device includes a fingerprint sensor and a processor. The fingerprint sensor is configured to acquire a plurality of fingerprint reference frames. The processor is coupled to the fingerprint sensor. The processor is configured to superimpose the plurality of fingerprint reference frames. The processor analyzes the plurality of fingerprint reference frames to determine multiple first regions and multiple second regions of the plurality of fingerprint reference frames. The processor calculates multiple reference pixel values of the plurality of fingerprint reference frames according to multiple weight value functions to generate a superimposed fingerprint frame. The weight value functions corresponding to the first regions of the plurality of fingerprint reference frames are linearly changed.
