Abstract
A method for acquiring a fingerprint image through a fingerprint image acquisition apparatus is provided. The method includes recognizing a finger of an user through a sensor included in the apparatus to generate an initial input fingerprint image when the finger contacts with a biometric recognition area of the display unit, acquiring a converted fingerprint image by converting the initial input fingerprint image in a pre-determined manner to reveal a characteristic of a pattern, included within the initial input fingerprint image, corresponding to a pattern signal reflected from at least a part of the display unit. The method further includes selecting a pattern removal fingerprint image, if a learned pattern image is stored in a memory, from the learned pattern image based on similarity. The similarity is calculated between the converted fingerprint image and a converted reference image.
