Title:
IRIS RECOGNITION IMAGING MODULE FOR MOBILE TERMINAL AND IMAGE ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2016/041437
Kind Code:
A1
Abstract:
The present invention provides an iris recognition imaging module for a mobile terminal. The mobile terminal comprises an iris recognition imaging module consisting of a mobile terminal mainboard, a processor chip integrated with a security function, a near infrared LED current driver, a memory having a secure read and write access function, a storage having a secure read and write access function, a power management module and a display screen. The iris recognition imaging module consists of a near infrared LED illuminating light source and an iris recognition imaging module optical component. The iris recognition imaging module optical component comprises a front and/or rear near infrared optical filter, an optical imaging lens, and an imaging sensor connecting line. The processor chip integrated with the security function is connected to the near infrared LED current driver and the iris recognition imaging module by means of connecting lines, thereby realizing feedback control. The near infrared LED current driver performs drive control on the radiation intensity and radiation period of the near infrared LED illuminating light source of the iris recognition imaging module.
