MULTI-WAVELENGTH BIOMETRIC IMAGING SYSTEM - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18027914 Titled 'MULTI-WAVELENGTH BIOMETRIC IMAGING SYSTEM'
Simplified Explanation
This abstract describes a method and device for flexible illumination using multiple wavelengths of light. The illumination source can emit light at different wavelengths continuously or selectively. The method involves capturing images at different wavelengths for different stages of biometric authentication processing. The camera can capture images sequentially or concurrently at these different wavelengths.
Original Abstract Submitted
Methods and apparatus for flexible illumination in which two or more different wavelengths are used in the illumination system. An illumination source may be configured to emit light at two or more different wavelengths, either continuously or selectively. A method may be implemented in which a first wavelength is emitted for capturing an image or images for a first portion of algorithmic processing for biometric authentication, and a second wavelength is emitted for capturing another image or images for a second portion of algorithmic processing for biometric authentication. The camera may sequentially capture two or more images at different wavelengths. As an alternative, the camera may be configured to concurrently capture two or more images at different wavelengths.
