Abstract
A device and method for biometric feature imaging are disclosed. The biometric feature imaging device comprises: an optical lens component adapted for optically imaging a biometric feature of a region of interest, an image sensor adapted for converting an optical image containing the biometric feature into an electronic image, an infrared light source adapted for illuminating the biometric feature of the region of interest with infrared light when the infrared light source is activated, and an optical filter unit; the optical filter unit comprises: a first optical filter adapted for blocking invisible light, a second optical filter adapted for allowing infrared light to pass therethrough, a driving mechanism adapted for moving the first optical filter and the second optical filter, and a driving controller; the driving controller is adapted for generating a first driving signal for driving the driving mechanism to move the first optical filter into an optical path of the optical lens component or a second driving signal for driving the driving mechanism to move the second optical filter into the optical path of the optical lens component.
