9. A fill light device, comprising:
a flash light;
a light guide, the light guide being located on a light-exiting side of the flash light;
an identification module, wherein the identification module is configured to perform face detection on a preview image of a camera module, perform pupil identification to determine a pupil position in response to detecting a face in the preview image, thereby a light-shielding area of the light guide is determined according to the pupil position; and
