ABSTRACT:
An apparatus and methods for capturing a fingerprint are provided. In a first example method, first fingerprint image may be obtained in a guard region within a captured image, the guard region including less than all of the captured image. A fingerprint region may be extracted from the captured image based on a predicted color distribution, the predicted color distribution based on color information associated with the first fingerprint image, the extracted fingerprint region including the first fingerprint image within the guard region and at least a portion of the fingerprint region extending beyond the guard region within the captured image. In a second example method, guard region may be defined within a picture boundary area, the defined guard region including less than all of the picture boundary area. At least one image may be captured, the captured image spanning the picture boundary area. Information associated with the captured image may be extracted from within the guard region. Portions of the captured image associated with a user's fingerprint may then be extracted based on the extracted information, the identified portions including a first portion within the guard region of the captured image and a second portion within the picture boundary area of the captured image outside of the guard region. In another example, an apparatus may be configured to perform either of the above-described first and second example methods.
