The method comprises detecting a finger of the user contacting a sensing area of the fingerprint sensor, initializing the fingerprint sensor with a predetermined sensor setting, acquiring a calibration sub-image which is confined in size to a subarea of the sensing area, determining whether or not a quality criterion is met for the acquired calibration sub-image, and if so acquiring one or more further sub-images confined in size to a subarea of the sensing area during a time period when the smartcard is not engaged in waiting time extension request signalling with a card reader, and combining a plurality of the acquired further sub-images into a representation of a fingerprint of the user."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fingerprint sub-image capture","description":"A method of a fingerprint sensing system arranged in a smartcard configured to acquire fingerprint data of a user with a fingerprint sensor for biometric authentication, and a fingerprint sensing syst","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12008425","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
