Patent number: 10713463Abstract: A display method of user interface and an electronic apparatus using the same are provided. The display method of user interface is applied to fingerprint registration, and includes: sensing an object and obtaining a swiping image of the object; analyzing the swiping image to obtain a plurality of feature points of the swiping image; generating a pre-registration dataset according to the feature points, and analyzing the pre-registration dataset to obtain an image adjusting parameter; and displaying a user interface, and adjusting a range of a filled region of a reference image on the user interface according to the image adjusting parameter. Therefore, the user learns a real-time information of fingerprint registration progress when the user performs fingerprint registration in a swiping manner.Type: GrantFiled: August 21, 2018Date of Patent: July 14, 2020Assignee: Egis Technology Inc.Inventors: Yuan-Lin Chiang, Jun-Chao Lu, Hsien-Jen Hsu

Patent number: 9807089Abstract: A biometrics data recognition apparatus includes a computer device and a biometrics data recognition device, which includes a biometrics data sensor, a control processor and a storage. The biometrics data sensor captures to-be-recognized biometrics data of an organism. The storage stores template biometrics data and website login data corresponding to each other. The control processor receives and judges whether the to-be-recognized biometrics data matches with the template biometrics data and outputs the website login data to the computer device if a match occurs. The computer device communicates with a cloud server and extracts login format data from the cloud server according to the website login data, and combines the website login data with the login format data to make the computer device log in a website corresponding to the website login data. A biometrics data recognition method and a non-transitory tangible computer readable medium are also disclosed.Type: GrantFiled: April 10, 2014Date of Patent: October 31, 2017Assignee: EGIS TECHNOLOGY INC.Inventors: Yuan-Lin Chiang, Jun-Chao Lu
