Abstract
A fingerprint image capturing system includes a fingerprint touch apparatus. The fingerprint touch apparatus includes a top surface, a bottom surface, a first normal line, a second normal line, a light input surface and a light output surface. The first normal line is perpendicular to the top surface. The light input surface and the light output surface are located on two opposite sides of the fingerprint touch apparatus. The light input surface corresponds to a planar light source module and the light output surface corresponds to an image capturing module. The planar light source module includes a light-emitting plane, and the light-emitting plane is parallel to the first normal line. The second normal line is perpendicular to the light-emitting plane. The second normal line and the light input surface form a first angle therebetween. The range of the first angle falls within 30 degrees to 45 degrees.
