FINGERPRINT RECOGNITION APPARATUS AND METHOD THEREOF OF ACQUIRING FINGERPRINT DATA
First Claim
1. A fingerprint recognition apparatus which comprises a fingerprint sensor to acquire a fingerprint image from a fingerprint placed on a fingerprint input widow, and extracts fingerprint data based on the fingerprint image, the fingerprint recognition apparatus comprising:
- a display unit which visually displays predetermined information; and
a control unit which receives the fingerprint image from the fingerprint sensor and extracts the fingerprint data accordingly, and if one of a fingerprint size, a fingerprint position, a degree of fingerprint contact, and a condition of minutiae points is not within a predetermined range, causes the display unit to display guide information including information about a corresponding error and instruction regarding a reinput of the fingerprint.

Abstract
A fingerprint recognition apparatus and a method thereof of acquiring fingerprint data are provided. The fingerprint recognition apparatus acquires a user'"'"'s fingerprint image through a fingerprint sensor, extracts information regarding a fingerprint size, a fingerprint position, a degree of fingerprint contact and a condition of minutiae points, and displays a corresponding error message and guide information through a display unit to encourage a reinput of fingerprint, if determining that the extracted information is not within a predetermined range. As a result, the user is encouraged to input a best quality fingerprint to allow extraction of good print data for either fingerprint enrollment or authentication. The information provided to the user may practically include detailed error and guide information regarding the fingerprint size, a degree with which a fingerprint is pushed to a certain side, a degree of contact or humidity of a fingerprint.

6. A method of acquiring a fingerprint image of a fingerprint recognition apparatus which registers a fingerprint using a fingerprint image acquired from a fingerprint placed on a fingerprint input window, the method comprising:
-
acquiring the fingerprint image from the fingerprint placed on the fingerprint input window; computing a value representing a fingerprint size, a fingerprint position, a degree of fingerprint contact, and a condition of minutiae points, based on the fingerprint area extracted from the fingerprint image; if one of the computed values is not within a predetermined range, displaying through a display unit corresponding error information and guide information regarding a reinput of the fingerprint; and if all of the computed values are within the predetermined range, acquiring the fingerprint data from the fingerprint image. - View Dependent Claims (7, 8, 9, 10)
