Assignee: WORLDCOIN FOUNDATION
Field: Audio-visual technology (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 19:
20. An iris scanning device, comprising:
a first camera that is configured to:
capture an image of a face of a user of the iris scanning device;

a second camera that is configured to:
capture a first image of an eye of the user subsequent to the image of the face of the user being captured; and
capture a second image of the eye of the user subsequent to the first image of the eye of the user being captured, wherein an iris of the eye of the user is located in a central region of the second image of the eye of the user,

a gimbal having a mirror mounted thereon;
a facial feature detector that is configured to:
identify facial features of the user based upon the image of the face of the user, the facial features of the user comprise a predicted location of the eye of the user; and
identify features of the eye of the user based upon the first image of the eye of the user, and

control circuitry that is configured to:
subsequent to capture of the image of the face of the user by the first camera, adjust an orientation of the gimbal based upon the facial features of the user, wherein the first image of the eye of the user is captured upon the orientation of the gimbal being adjusted based upon the predicted location of the eye of the user, wherein the mirror mounted on the gimbal is oriented to cause the first image of the eye of the user to be captured; and
subsequent to capture of the first image of the eye of the user by the second camera, adjust the orientation of the gimbal based upon the features of the eye of the user identified from the first image of the eye captured by the second camera, wherein the first image of the eye is determined to not satisfy criteria based upon the features of the eye, wherein the second image of the eye of the user is captured upon the orientation of the gimbal being adjusted based upon the features of the eye of the user, wherein the mirror mounted on the gimbal is oriented to cause the second image of the eye of the user to be captured, wherein the second image of the eye is determined to satisfy the criteria such that a code is caused to be generated based upon the second image of the eye of the user.
