Summary: | The invention relates to a face recognition method based on a camera module and the camera module, and the camera module comprises a driving power supply, which comprises a first driving circuit and a second driving circuit; a change-over switch, which is connected to the driving power supply; an electrochromic optical filter, which is connected to the change-over switch; an optical lens, which is connected to the electrochromic optical filter and is used for acquiring external imaging light. The technical scheme of the invention is based on the effect of the change-over switch; wherein the electrochromic optical filter realizes switching of three states in the first driving circuit, the second driving circuit or the open circuit, so that light waves penetrating through the electrochromic optical filter can be changed, namely, the filtering characteristic of the electrochromic optical filter can be adjusted; in this way, the switching of different states can be met without installing a plurality of cameras.
