Abstract
Provided are a method of recognizing a fingerprint and a device including the same. The method of recognizing a fingerprint includes obtaining a fingerprint image from a fingerprint sensor, determining whether a pixel in the fingerprint image is defective based on a dispersion value of the pixel with respect to time, in response to determining that the pixel is defective, generating an interpolated pixel value of the pixel by performing interpolation on a first pixel value of the pixel based on a second pixel value of another pixel different from the pixel, and correcting the fingerprint image based on the interpolated pixel value.
