Abstract

The invention discloses a control method for an infrared light source assembly. The control method is used for an iris identification module. The infrared light source assembly comprises an actuator and an infrared light source connected with the actuator. The control method comprises the steps of collecting a human face image corresponding to a human face; processing the human face image to identify the position of human eyes; and controlling the actuator to adjust an emission direction of an infrared light beam of the infrared light source to enable the infrared light beam to cover the human eyes, wherein the light spot size of the infrared light beam on a human face is matched with the size of the human eyes. The invention furthermore discloses a control apparatus, an electronic apparatus and a computer readable storage medium. According to the control method, the control apparatus, the electronic apparatus and the computer readable storage medium, by controlling the emission direction of the infrared light source, the infrared light source can accurately irradiate the human eyes to assist in obtaining a high-quality iris image.

Description
