Title: SYSTEMS AND METHODS OF ILLUMINATION CONTROL FOR BIOMETRIC CAPTURE AND LIVENESS DETECTION
Abstract:
The present disclosure describes illumination control for biometric capture with liveness detection. A first near infra-red (NIR) illuminator illuminates, during a first time slice, a right eye and/or a left eye, and may be located within a predetermined distance from a sensor. A second NIR illuminator may illuminate, during a second time slice, the right eye and/or left eye. The second NIR illuminator may be located at a second distance larger than the predetermined distance. A third NIR illuminator may illuminate, during a third time slice, the right eye and/or left eye, and may be located at a third distance that is larger than the predetermined distance. The sensor may be used to detect a red-eye effect during the first time slice, and capture an image of the right eye and/or left eye during the second time slice, and a second image during the third time slice.
