IRIS IMAGING APPARATUS

摘要

The object of the invention is to provide iris image pickup apparatus capable of acquiring a high-accuracy iris image in a short time, the iris image pickup apparatus using a low-cost configuration comprising one wide angle camera and one telephotographic camera.

According to the invention, a wide angle camera (25) for picking up an image of an object, a telephotographic camera (22) for bringing the iris of an object into focus and picking up an enlarged image of the iris are provided, as well as a range finder (24) for measuring the distance to the object. Or, the iris image pickup apparatus includes a wide angle camera (25) and a telephotographic camera (22), wherein the long sides of a rectangular image pickup element in the wide angle camera (25) are arranged in the same direction as the height of the object, that is in portrait orientation and that the wide angle camera is mounted on a tilt table (20). Or, the telephotographic camera (22) mounted on the tilt table (20) is arranged so that its optical axis crosses the rotation axis of the tilt table (20) in the same plane. This allows high-speed acquisition of an iris position based on an image picked up by the wide angle camera (25).
