Method and apparatus for recognizing fingerprint
First Claim
1. A method of recognizing a fingerprint, comprising:
- receiving a request for a fingerprint mode;
in response to the request for the fingerprint mode, displaying a guide area, the guide area located in at least one area of a display unit adjacent to a fingerprint scan sensor;
receiving a finger touch for performing a fingerprint scan via the guide area;
providing guide information related to fingerprint recognition based on the finger touch detected via the guide area by determining at least one attribute related to the finger touch; and
displaying, when the at least one attribute does not meet a predetermined condition, information making a request for changing the finger touch,wherein displaying the information making the request for changing the finger touch comprises extracting sizes of a major axis and a minor axis of the finger touch, and comparing the extracted sizes of the major axis and the minor axis.

Abstract
A method and apparatus for recognizing a fingerprint. The method includes displaying a guide area corresponding to a finger touch in at least one area of a display unit; and providing guide information related to fingerprint recognition based on a touch detected via the guide area. The apparatus includes a display unit configured to display a guide area corresponding to a finger touch in at least one area in a fingerprint mode; an input unit configured to detect a touch input, wherein the input unit is integrally configured with the display unit; a fingerprint scan sensor located in an area adjacent to the guide area of the display unit; and a controller configured to provide guide information related to fingerprint recognition based on a touch detected via the guide area in the fingerprint mode.

21. A method of registering a fingerprint by an electronic device, the method comprising:
-
receiving a request for a fingerprint mode; in response to the request for the fingerprint mode, displaying a guide area, the guide area located in an area of a display unit adjacent to a fingerprint scan sensor; displaying guide information instructing a user to place a finger in the guide area by determining at least one attribute related to the finger touch; displaying, when the at least one attribute does not meet a predetermined condition, information making a request for changing the finger touch; analyzing a touched area and a preset area when the finger touch is detected in the guide area; displaying information instructing a larger finger touch when the touched area is less than the preset area; and collecting fingerprint information corresponding to the finger touch via the fingerprint scan sensor, when the touched area is greater than the preset area, wherein displaying the information making the request for changing the finger touch comprises extracting sizes of a major axis and a minor axis of the finger touch, and comparing the extracted sizes of the major axis and the minor axis. - View Dependent Claims (22)
