Abstract
It is an objective of the present invention to provide a biometric imaging device comprising an optical lens component for performing optical imaging (including static image and dynamic image) on a biometric of a region of interest; an image sensor for converting an optical image of said biometric into an electronic image (including static image and dynamic image); and a micromotor controller for acquiring, delivering, or analyzing image quality information of the electronic image, analyzing in real time the definition of the image according to the image quality information of the electronic image, and feeding back said information in real time so as to adjust the optical lens component to perform autofocus control of the biometric of the region of interest.
Claims29
A biometric imaging device (100), comprising:
- an optical lens component (110) for performing optical imaging on a biometric (12) in a region of interest (13);
- an image sensor (120) for converting an optical image comprising said biometric (12) into an electronic image;
- a micromotor (140) for adjusting said optical lens component (110);
