Abstract

A method for operating an electronic device is provided. The method includes detecting a fingerprint, detecting reference value based on situation information of the electronic device, and performing a fingerprint recognition based on the detected fingerprint and the reference value. A method for operating an electronic device is not limited to the above method, and other embodiments are possible within the same or similar scope as the present disclosure.

Claims

1. A method for operating an electronic device, the method comprising:

detecting a fingerprint;

detecting a reference value, based on situation information of the electronic device; and

performing a fingerprint recognition based on the detected fingerprint and the reference value.

2. The method of claim 1,

wherein the situation information comprises at least one of information on a motion of the electronic device, information on a posture of the electronic device, and information on a movement of the electronic device, or

wherein the situation information comprises information on a mode specified based on the motion, posture, and movement of the electronic device.

3. The method of claim 2, wherein the information on the motion of the electronic device, the information on the posture of the electronic device, or the information on the movement of the electronic device is acquired through at least one of an acceleration sensor, a tilt sensor, a gesture sensor, a gyro sensor, a grip sensor, a touch sensor, a light sensor, or a biometric sensor included in the electronic device.

4. The method of claim 1, wherein the situation information comprises information on an orientation of a hand grasping the electronic device or information on a position where the electronic device is worn on a user'"'"'s body.

5. The method of claim 4, wherein the information on the orientation of the grasping hand or the wearing position is determined based on the movement of the electronic device, acquired through at least one of an acceleration sensor, a tilt sensor, a gesture sensor, a gyro sensor, a grip sensor, a touch sensor, a light sensor, and a biometric sensor included in the electronic device or based on a biometric sensor included in the electronic device.

6. The method of claim 1, wherein the situation information comprises information determined for an orientation of a user'"'"'s hand with which the user inputs the detected fingerprint.

7. The method of claim 6, wherein the information determined for the orientation of the user'"'"'s hand is determined based on information on a motion, a posture, or a movement of the electronic device.

8. The method of claim 1, wherein the reference value includes information on at least one fingerprint image stored before a detection time of the fingerprint or information on at least one category including at least one fingerprint image.

9. The method of claim 8,

wherein, when a swipe type fingerprint recognition sensor is used, the category is identified based on at least one of a direction in which a user swipes his/her finger, an orientation of a user'"'"'s hand with which the user inputs the fingerprint, and a finger of which the fingerprint is input, and

wherein, when a touch type fingerprint recognition sensor is used, the category is identified based on at least one of an orientation of a fingertip, the orientation of the user'"'"'s hand with which the user inputs the fingerprint, and a finger of which the fingerprint is input.

10. The method of claim 8, wherein the reference value comprises information on priorities specified for the at least one fingerprint image or the at least one category.

11. An electronic device comprising:

a fingerprint recognition sensor configured to detect a fingerprint; and

a processor configured to;

detects a reference value, based on situation information of the electronic device at a time when the fingerprint is detected; and

perform a fingerprint recognition based on the detected fingerprint and the reference value.

12. The electronic device of claim 11, wherein the processor is further configured to determine, as the situation information, at least one of information on a motion of the electronic device, information on a posture of the electronic device, or information on a movement of the electronic device or comprises information on a mode specified based on a motion, a posture, and a movement of the electronic device.

13. The electronic device of claim 12, wherein the processor is further configured to acquire the information on the motion of the electronic device, the information on the posture of the electronic device, or the information on the movement of the electronic device through at least one of an acceleration sensor, a tilt sensor, a gesture sensor, a gyro sensor, a grip sensor, a touch sensor, a light sensor, or a biometric sensor included in the electronic device.

14. The electronic device of claim 11, wherein the processor is further configured to determine, as the situation information, information on an orientation of a hand grasping the electronic device or information on a position where the electronic device is worn on a user'"'"'s body.

15. The electronic device of claim 14, wherein the processor is further configured to determine the information on the orientation of the grasping hand or the wearing position, based on the movement of the electronic device, acquired through at least one of an acceleration sensor, a tilt sensor, a gesture sensor, a gyro sensor, a grip sensor, a touch sensor, a light sensor, or a biometric sensor included in the electronic device or based on a biometric sensor included in the electronic device.

16. The electronic device of claim 11, wherein the processor is further configured to allow the situation information to include information determined for an orientation of a user'"'"'s hand with which the user inputs the detected fingerprint.

17. The electronic device of claim 16, wherein the processor is further configured to determine the information determined for the orientation of the user'"'"'s hand, based on information on a motion, posture, or movement of the electronic device.

18. The electronic device of claim 11, wherein the processor is further configured to allow the reference value to include information on at least one fingerprint image stored before a detection time of the fingerprint or information on at least one category including at least one fingerprint image.

19. The electronic device of claim 18,

wherein, when a swipe type fingerprint recognition sensor is used, the processor is further configured to identify the category, based on at least one of a direction in which a user swipes his/her finger, an orientation of a user'"'"'s hand with which the user inputs the fingerprint, or a finger of which the fingerprint is input, and

wherein, when a touch type fingerprint recognition sensor is used, the processor is further configured to identify the category, based on at least one of an orientation of a fingertip, the orientation of the user'"'"'s hand with which the user inputs the fingerprint, or a finger of which the fingerprint is input.

20. The electronic device of claim 18, wherein the processor is further configured to specify priorities of the at least one fingerprint image or the at least one category and allow the reference value to include the determined priorities.
