COMPACT IMAGING DEVICE

摘要

A compact image steering and focusing device has a generally rectangular frame containing at least one illuminator and at least one and preferably two cameras and a pan/tilt mirror on a tilting frame. There is a tilt axis through the frame. A tilt motor is attached to the frame to turn the frame about the tilt axis. Another camera is positioned in optical alignment with the pan/tilt mirror. The device can fit behind the cover plate of an automated teller machine. Images from the cameras on the tilting frame are used to focus the other camera on one eye of the automated teller machine user to identify the user by iris analysis and comparison to an iris image or iris code on file.
