The method includes: acquiring a first fingerprint image and at least one second fingerprint image, where a screen luminance for acquiring the first fingerprint image is higher than a screen luminance for acquiring the at least one second fingerprint image; determining a third fingerprint image according to the first fingerprint image and the at least one second fingerprint image, where the third fingerprint image is an interference image having a same exposure time as the first fingerprint image; and performing interference cancellation on the first fingerprint image according to the third fingerprint image to obtain a fourth fingerprint image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for acquiring fingerprint, chip and terminal device","description":"Embodiments of the present application provide a method and an apparatus for acquiring a fingerprint, a chip and a terminal device, which may reduce interference caused by ambient light, temperature a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-10515254","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.
