Abstract
The present application discloses an iris identification system and an iris identification method thereof. The iris identification system includes: a camera module including at least two cameras, the cameras having different depths of field and being configured to capture iris images; a distance detection apparatus configured to detect a distance between a user and the camera module; a processing chip configured to find, according to the detected distance, a depth of field corresponding the distance and control a camera having the depth of field to be turned on, and further configured to control multiple cameras in the camera module to be turned on simultaneously until one camera has captured an ideal image. At least two cameras having different depths of field are disposed in the iris identification system provided in the present application; a camera having a suitable depth of field is turned on correspondingly according to a detected distance between a user and a camera module to capture an image, or multiple cameras are turned on simultaneously until one camera has captured a clear iris image. The present application achieves good man-machine friendliness and a short capturing …
