Cable driven image steering and focusing device
First Claim
1. A compact image steering and focusing device comprising:
- a. a housing;
b. a platform rotatably attached to the housing for rotation about a pan axis;
c. a first stepper motor;
d. a cable drive connected between the platform and the first stepper motor to enable the first stepper motor to rotate the platform about the pan axis;
e. a pair of substantially parallel, spaced apart arms extending from the platform, there being a tilt axis passing between and equidistant from the arms;
f. a primary mirror pivotably attached between the arms and able to be rotated around the tilt axis;
g. a mirror drive motor attached to the platform;
h. a mirror cable drive connected between the primary mirror and the mirror drive motor in a manner to be able to rotate the primary mirror about the tilt axis;
i. a primary lens positioned on the housing and aligned with the primary mirror; and
j. a lens motor attached to the housing and connected to the primary lens in a manner to be able to move the lens along an optical path toward and away from the primary mirror.

Abstract
A compact image steering and focusing device has a generally rotatable platform that carries a pan/tilt mirror. The rotatable platform, at least one motor driven lens and a camera are mounted on a housing. Two drive motors each with an associated cable are provided to rotate the rotatable platform and tilt the mirror. Light reflected from a subject is captured by the mirror and directed through the lens to the camera. The device can fit behind the cover plate of an automated teller machine. This system is preferably used with a narrow field of view camera and two wide field of view cameras. Images from the wide field of view cameras are used to focus the narrow field of view camera on one eye of the automated teller machine user to identify the user by iris analysis and comparison to an iris image on file.
