Abstract

The present disclosure provides an apparatus and a method for fingerprint imaging. The apparatus includes: a light source configured to generate light, wherein a light intensity distribution of the light generated by the light source conforms to a preset encoding mode; a sensing surface on which the light generated by the light source forms a signal light with fingerprint information; and an imaging module configured to image the signal light to obtain a fingerprint image. Embodiments of the present disclosure can encode the fingerprint image by the encoding mode and can 'encrypt' the fingerprint image by the encoding mode, thus a clear fingerprint image can be obtained by decoding based on obtaining the preset encoding mode, which can effectively improve the security of fingerprint imaging.
