Abstract
A fingerprint sensor module includes a lens, a filter, a first reflector, an image capturing module for capturing a first fingerprint image and a second fingerprint image, and at least one first light source for providing the needed light source at the time of the image capturing module capturing the fingerprint image. A top surface and a bottom surface of the lens are planes. The lens defines at least one first area and a second area. The filter is disposed under the lens. The filter is corresponding to the first area of the lens for reflecting the first fingerprint image corresponding to the first area. The first reflector is disposed under the lens. The first reflector is corresponding to the second area of the lens for reflecting the second fingerprint image corresponding to the second area.
