Abstract

PROBLEM TO BE SOLVED: To eliminate the necessity of an expensive camera, an optical processing system for zooming up, etc., and to reduce the cost of the system by photographing only a face by a camera and then photographing only eyes in the face by another camera. SOLUTION: The image of the whole face 10 is photographed by a main camera 1. Namely a person approaching the front of the main camera 1 is detected and the face 10 of the person is photographed. Then the positions of eyes 11 are analyzed. Namely the positions of eyes 11 included irises 12 to be identified from the whole face 10 are analyzed based on the picture data of the photographed person's face. Then a camera control part 4 is driven and a moving camera 2 is focused on one eye out of both the eyes based on the position data of the eyes 11 to be analyzed and the image of the eye is photographed by the camera 2. Then iris data are obtained. Thus the image of the right eye e.g. photographed by the camera 2 is analyzed by an iris analyzing part 6 to obtain the iris data of the right eye. A feature extracting part 7 extracts data characterizing the iris based on the iris data.

2. Description of the Related Art Fingerprints have long been used as a method for identifying individuals. The iris of the eye is also effective as information for personal identification like a fingerprint, and a method of acquiring the feature is also introduced (Japanese Patent Publication No. 5-841166). Here, the step of illuminating the eye including the iris and the pupil, the step of obtaining an image of the iris and the pupil, the step of extracting the feature based on the image of the iris, and the feature of the iris extracted in the process A technique is described in which an individual is identified by comparing a sample with a sample. In this case, an image of the entire face is captured by the camera, and the position of the eyes is recognized from the image of the entire face. After recognizing the position of the eyes, the camera is pointed to one of the two eyes, and only that eye is zoomed up. Then take a detailed image of the eye. The captured eye image is analyzed to obtain data on the iris of the eye.

<Operation> FIG. 2 is a control flowchart of the moving camera of the iris recognition system according to the present invention. This control flowchart is for photographing an iris using two cameras. In step S1, the main camera 1 captures an image of the entire face 10. That is, main camera 1
Captures a person approaching in front of and captures the face 10 of the person. In step S2, the position of the eye 11 is analyzed.
That is, based on the image data of the human face 10 photographed in step S1, the iris 1 to be identified from the entire face 10 is determined.
The position of the eye 11 including 2 is analyzed. In step S3, the camera control unit 4 is operated to adjust the moving camera 2 to one of the two eyes from the data of the position of the eye 11 analyzed in step S2. Step S4
, An image of the eye is taken by the moving camera 2. Thereafter, in step 5, iris data is obtained. Thus,
For example, an image of the right eye captured by the moving camera 2 is analyzed by the iris analyzer 6 to obtain iris data of the right eye. Based on the iris data, the feature extraction unit 7 extracts data characterizing the iris. In the process, the determination unit 8 inputs the information of the right eye to the iris analysis unit 6 and the feature extraction unit 7 to generate iris data. Then, the identification control unit 9 checks the iris data against the sample data stored in the identification control unit 9 for identifying an individual. As a result, the individual can be identified.
