Acquiring/Recognising Eyes TRIZ Cases
- Integrated Face And Iris Imaging for Compact Authentication Terminals
A shared drive unit coordinates wide-range face and narrow-range iris capture, reducing terminal size and authentication time.
- Eye-Status Detection Using Dynamic Eye-Contour Standard Deviations
Fixed thresholds lose accuracy across facial distances and features; dynamic eye-contour standard deviations improve status detection.
- Iris Recognition Module with Proximity-Gated LED Exposure
During iris authentication, proximity sensing reduces or stops LED exposure when the user moves too close, limiting eye strain.
- Display Eye-Imaging Optics With Nonparallel Optical Axes
Nonparallel finder and eye-imaging axes capture the user's eye across pupil shifts without enlarging the display apparatus.
