SG11201906529PA - Optical fingerprint verification method and mobile terminal - Google Patents

Abstract

themobile terminal controls the optical sensor to detect a current external ambient light intensity when the mobile terminal receives a fingerprint collecting instruction the mobile terminal controls the inner light source of the optical fingerprint identification component to collect fin.erprint data () INTERNATIONAL APPLICATION PUBLISHED UNDER THE PATENT COOPERATION TREATY (PCT) (19) World Intellectual Property Organization International Bureau (43) International Publication Date 08 November 2018 (08.11.2018) WIPO I PCT 011101 010 VIII ono o omuloolioluo oimIE (10) International Publication Number WO 2018/201950 Al 201 202 203 204 205 (51) International Patent Classification: GOOK 9/00 (2006.01) (21) International Application Number: PCT/CN2018/084485 (22) International Filing Date: 25 April 2018 (25.04.2018) (25) Filing Language: English (26) Publication Language: English (30) Priority Data: 201710305873.7 03 May 2017 (03.05.2017) CN (71) Applicant: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.
