    Abstract: PURPOSE: A sweeping apparatus for fingerprint reading and a method are provided so that it exacts about the fingerprint scarping within the range that it expects because for user, the fingerprint recognition will possible, the whole fingerprint is embodied and it recognizes. CONSTITUTION: A visual improvement part(120) improves a slice image extracted from a sweeping mode finger print recognition sensor(110). In perpendicular a image register part(130) is the location having the correlation mean value which most highs about the slice image, perpendicular the visual registration is proceed in the image which is Y-matching. A rotation image register part(140) is proceed the rotated image Y-matching about the slice image in which perpendicular the visual registration operates. In the rotation image register part is the rotation angle having the correlation value which most highs among the total rotation range, Y-matching is proceed.
