1. An iris recognition method, applied for an electronic device, wherein the electronic device comprises an iris recognition module and a motion sensor, the iris recognition module comprises an infrared camera, and the method comprises:

  • detecting motion information of the electronic device by the motion sensor;

    when the motion information of the electronic device satisfies a preset condition, starting the infrared camera and capturing an image of a user by the infrared camera; and

    when determining that there is a face contour in the image, performing iris recognition by the iris recognition module;

    wherein, the iris recognition module further comprises an infrared light source, and performing the iris recognition by the iris recognition module when determining that there is the face contour in the image comprises;

    filling light by the infrared light source;

    capturing an iris image by the infrared camera;

    positioning an iris by extracting an inner boundary of the iris using a grayscale histogram of the iris image and by extracting an outer boundary of the iris using Hough transform method;

    processing the iris image based on the position of the iris to extract feature information;

    determining whether the feature information matches pre-stored iris feature information; and

    when the feature information matches the pre-stored iris feature information, determining that the iris recognition is successful.
