  • Patent number: 11335115
    Abstract: A fingerprint recognition technology is disclosed. More specifically, embodiments of the present invention provide a fake fingerprint identification device and a method for driving the identification device. According to the device and the method, an alternating voltage is applied to read a fingerprint such that the fingerprint is identified and physical authentication is made whether the fingerprint is live or fake when the frequency of a TX or RX ultrasonic signal generated by the application of the alternating voltage varies. Therefore, the device and the method can be used to accurately identify whether a fingerprint is live or fake and is thus effective in preventing harmful effects caused when a fake fingerprint is authenticated.

  • Patent number: 11335116
    Abstract: The present invention relates to an apparatus and method for identifying a fake fingerprint by using impedance, which enables identification of a fingerprint or fake fingerprint by measuring an impedance value of a fake fingerprint made of silicon or gelatin. In the present invention, a fingerprint recognition module identifies, through a driver IC, an impedance value of an ultrasonic wave reflected from a finger and identifies a fake fingerprint on the basis of a changed impedance value, and determines a fake fingerprint by measuring an impedance value in an ultrasonic wave which is emitted from the fingerprint recognition module, collides with a fake fingerprint, and is then reflected therefrom.

  • Publication number: 20220094862
    Abstract: An electronic device includes a pixel array that outputs a raw image including color pixels and specific pixels, a logic circuit that outputs a first binned image by performing first binning on pixels in a row direction for each unit kernel of the raw image, and a processor that outputs a second binned image by performing second binning on the first binned image. When a unit kernel includes at least one of the specific pixels, a column to which the at least one specific pixel belongs is read out at a readout timing different from a readout timing of a column to which none of the specific pixels belong and undergoes the first binning. The second binning combines a third binned image of the column to which none of the specific pixels belong with a fourth binned image of the column to which the at least one specific pixel belongs.
