  • Patent number: 11600098
    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.

  • Publication number: 20210350506
    Abstract: The present disclosure provides a method and an apparatus for processing an image, an imaging device and a storage medium. The method includes: acquiring a to-be-processed blurred image, and determining an initial blur function and an initial clear image; and acquiring a processed clear image and a processed blur function based on an iterative operation of a blurred image, a blur function and a clear image. Embodiments of the present disclosure can deblur the blurred image by the iterative operation to obtain a clear image with higher quality.
