Classification: CPC G  H | IPC G  H

Claim 9:
10. A method performed by an iris scanning device for capturing images of irises of users, the method comprising:
capturing an image of a face of a user of the iris scanning device by way of a first camera comprised by the iris scanning device;
identifying facial features of the user based upon the image of the face of the user, the facial features of the user comprise a prediction location of the eye of the user;
computing a desired angle between the ee of the user and a mirror mounted on a gimbal based on the facial features of the user, wherein the gimbal and the mirror are comprised by the iris scanning device;
adjusting an orientation of the gimbal having the mirror mounted thereon based upon the facial features of the user such that an angle between the eye of the user and the mirror mounted on the gimbal is the desired angle;
upon adjusting the orientation of the gimbal based upon the facial features of the user, capturing an image of the eye of the user by way of a second camera comprised by the iris scanning device, wherein the mirror mounted on the gimbal is oriented to cause the image of the eye of the user to be captured;
identifying features of the eye of the user based upon the image of the eye of the user;
determining whether the image of the eye of the user satisfies criteria based upon the features of the eye;
generating a code based upon the image of the eye of the user when the image of the eye satisfies the criteria; and
when the image of the eye does not satisfy the criteria:
adjusting the orientation of the gimbal having the mirror mounted thereon based upon the features of the eye; and
upon adjusting the orientation of the gimbal based upon the features of the eye, capturing a second image of the eye of the user by way of the second camera.
