Abstract
In accordance with an embodiment, the prism is made slimly to correct the distortion of the fingerprint image such as trapezoidal distortion or the like. Therefore, it is possible to manufacture the optical fingerprint recognition apparatus of a compact size. Further, the imaging lens is arranged to have a de-centering amount and/or a tilt angle with respect to the optical axis, which leads to an effect to implement resolution approaching the diffraction limit.
