Iris recognition device and method

The embodiment of the invention provides iris recognition equipment and method, and the equipment comprises a plurality of second lenses with different focal lengths, so that a zoom lens does not need to be used, and a processor obtains the position of the face of a person under the condition that the existence of the face of the person is detected, thereby determining the second lens which can clearly shoot the position, and improving the user experience. Therefore, iris recognition is carried out according to the shot clear image, the person only needs to move to the effective shooting area of any second lens during iris recognition, and the limitation of iris recognition on the movement route of the person is effectively reduced. Moreover, the iris recognition is carried out on the third image only when the detection result of the first image is a living body, thereby effectively reducing the success rate of impersonating the identity of other people through a face wearing mode and the like, namely improvi
