Abstract
An iris collection method is used for an electronic device. The electronic device includes an iris recognition module. The iris recognition module includes an infrared light source. The iris collection method includes acquiring a distance between the iris recognition module and an iris of a person to be recognized; adjusting light intensity of transmitted infrared light according to the distance by the infrared light source, so that light intensity of infrared light reaching the iris of the person to be recognized is a target light intensity; and collecting an iris image of the iris by acquiring infrared light having the target light intensity reflected by the iris. An electronic device and a computer readable storage medium are also disclosed.
