Abstract
A method and apparatus for capturing rolled fingerprint images are provided. The method for capturing rolled fingerprint image acquires elemental image frames from a fingerprint that touches and rolls on a fingerprint input window, acquires improved image frames through preprocessing by removing an image that does not overlap between adjacent elemental image frames, extracts main data of adjacent improved image frames to acquire main data image frames, and merges images of the main data image frames to acquire a rolled fingerprint image.
