Abstract
Disclosed is a fingerprint image capture device, comprising an optical guide element, one or more than one fill-in light units and an image acquisition sensing unit. Wherein, the optical guide unit has a fixed position able to provide for the fixed placement of a finger and a fixed focus and an optical guide part able to provide for image correction. Further, during the fingerprint image capturing, the fill-in light unit is used to proceed lighting at the outside of the fixed position so that the image of the finger placed on the fixed position can be transmitted by reflection using the principle of light reflection and refraction after the light source is guided in by the optical guide part for the image acquisition sensing unit to directly capture the finger image on the fixed position(that is the solid image of the fingerprint on the finger), enabling to exclude going through the plurality of times of reflection and refraction required by ordinary capture device for forming images, which bring forth trivial components and the image acquisition distortion.
