Abstract
There is provided a method for obtaining a user authentication image using pressure sensing. The method includes dividing a pressure sensing area corresponding to a fingerprint input window, with which a biometric feature of a user is brought into contact, into a plurality of partial areas, acquiring a plurality of image frames captured through the fingerprint input window and obtaining, for the partial areas, respective pressure sensing values synchronized with a capturing time of each of the image frames. The method further includes generating the user authentication image from the image frames based on comparison results between the pressure sensing values respectively obtained for the partial areas and one or more predetermined thresholds.
