Patent Images
1. An iris recognition camera, comprising:
- a driving barrel configured to support a single alignment of at least two lenses configured to serve as a wide-angle lens at all times, wherein the at least two lenses are respectively fixed to a predetermined position of the driving barrel so that intervals between all lenses in the single alignment of the at least two lenses are immutable;
a moving device comprising a single drive motor configured to reciprocatingly move the driving barrel to perform both focus and zoom operations at the same time; and
a position sensor attached to a casing of the iris recognition camera that is configured to detect a position of the driving barrel within the camera and configured to detect a user of the iris recognition camera.

12. A method of operation for an iris recognition camera, comprising:
-
detecting a user; moving via a moving device comprising a single drive motor a camera lens of the iris recognition camera to an initial position detected by a position sensor, that is attached to a casing of the iris recognition camera, after the position sensor detects the user; thereafter reciprocatingly moving via the moving device comprising the single drive motor the camera lens to perform both focus and zoom operations from the initial position to an image pickup location where a user'"'"'s iris can be captured, wherein the camera lens includes at least two lenses which are fixed respectively to a predetermined position of a driving barrel so that intervals of all lenses of the at least two lenses are immutable; and performing the image pickup using an image pickup device. - View Dependent Claims (13, 14, 15, 16)
