BIOMETRIC DETECTION MODULE WITH DENOISING FUNCTION AND BIOMETRIC DETECTION METHOD THEREOF
First Claim
1. A biometric detection module, configured to be attached to an eyeglass temple and detect at least one biometric characteristic from a skin region behind ear, the biometric detection module comprising:
- a detection unit comprising;
a light source module configured to emit green light, red light and infrared light in a time division manner to illuminate the skin region;
a detection region configured to detect penetrating light emitted from the light source module for illuminating the skin region and passing through body tissues to correspondingly generate a green light signal, a red light signal and an infrared light signal; and
a control module configured to control the light source module to emit light, determine a filtering parameter according to the green light signal to accordingly filter the red light signal and the infrared light signal, and calculate the biometric characteristic according to at least one of the green light signal, a filtered red light signal and a filtered infrared light signal.

Abstract
A biometric detection module including a light source module, a detection region and a control module is provided. The light source module is configured to emit green light, red light and IR light in a time division manner to illuminate a skin surface. The detection region is configured to detect penetration light emitted from the light source module for illuminating the skin surface and passing through body tissues to correspondingly generate a green light signal, a red light signal and an IR light signal. The control module is configured to determine a filtering parameter according to the green light signal to accordingly filter the red light signal and the IR light signal, and calculate a biometric characteristic according to at least one of the green light signal, a filtered red light signal and a filtered IR light signal.
