  • Method of recognizing contactless fingerprint and electronic device for performing the same
    Patent number: 9483680
    Abstract: A method of recognizing a contactless fingerprint is provided. The method includes displaying a guide screen for recognizing the contactless fingerprint on a display, receiving an input image of a target object positioned according to the guide screen by using a camera, and determining whether the received input image is suitable for fingerprint recognition.
    Type: Grant

  • Apparatus and methods for capturing a fingerprint
    Patent number: 7970185
    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.
