DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 Hereinafter, an ID discriminating apparatus according to a specific embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external view showing a main configuration of the ID discriminating apparatus. As shown in FIG.
The D determining device includes a controller 1 and an ITV camera 2 for obtaining iris data of eyes. And
The controller 1 includes an A / D converter 1a that converts an analog video signal from the camera 2 into a digital signal,
A display device 1b, an interface 1c for sending an ID discrimination OK output to the outside, a numeric keypad 1d, and C as control means
A PU 1e, a ROM 1f for storing a processing program, fixed data, and the like, and a RAM 1g for temporarily storing processing data, input data, and the like, are connected to each other via a bus.

Hereinafter, the operation of the ID discriminating apparatus having the above configuration will be described with reference to the flowcharts shown in FIGS. FIGS. 2 and 3 show flowcharts at the time of registration and at the time of comparison stored in the ROM 1f of the controller 1 and executed under the control of the CPU 1e. First, in the registration flowchart shown in FIG. 2, when a registration mode is set from the numeric keypad 1d, for example, when a predetermined number is input (step S21), the display device 1b is set.
To display a "registration mode" (step S2), and urge the person to be registered to turn their eyes to the ITV camera 2.

By displaying the "registration mode", the person to be registered points to the ITV camera 2, thereby extracting the feature points of the iris and storing the individual feature point data in the RAM 1g (steps S24 and S25). . Thereafter, if there is a setting for terminating the registration mode from the numeric keypad 1d, for example, a setting by inputting a predetermined number (step S26),
The registration is terminated by deleting the “registration mode” displayed on the display device 1b (step S27).

Next, in the collation flowchart shown in FIG. 3, when the person to be collated turns the ITV camera 2 to input an eye image (step S31), the eyelid is closed for a predetermined time. A change in the state of the eyes from the open state is detected (step S32), and based on the detection, feature point data of the iris is extracted, and there is any data whose feature point data matches the registered data in the RAM 1g. It is determined whether or not it is (step S33). If there is data that matches the registered data, “ID discrimination OK” is displayed on the display device 1b (step S35), and
For example, in order to control the opening and closing of the electric lock of the door to control the traffic,
A determination OK output is output for a predetermined time and the process is terminated (step S
36). If the result of any of steps S31, S32 and S33 is NO, the display device 1b
Is displayed as "NG" (step S34).

Therefore, according to the first embodiment,
Since a predetermined state change of the eyelid is detected from an image of the eye directed to the camera, that is, an eye state change from a state where the eyelid is closed to a state where the eyelid is opened for a predetermined time is detected and ID determination is started. In addition, the ID can be determined only for a person who intends to determine the ID, so that the security can be improved without unnecessary wasting of the device.

The present invention can be implemented in accordance with an embodiment described later, in addition to the above-described first embodiment. Embodiment 2 FIG. In the first embodiment, the CPU 1e
Detects an eye state change in which the eyelid changes from a closed state to an open state for a predetermined period of time and starts ID discrimination, but an eye state change in which the operation from closing to opening of the eyelid is performed a predetermined number of times. May be detected to start the ID determination. In this case, a more reliable start time can be determined.

Embodiment 3 Also, instead of opening and closing the eyelids, the CPU 1e may detect an eye state change in which the eyeball moves left and right, up and down, or a combination thereof once or a predetermined number of times to start ID discrimination. Good.

Embodiment 4 Further, in each of the above-described embodiments, the ID determination based on the iris data collation is started based on the detection of the eye state change based on the image input of the ITV camera. Other setting means such as setting by simply operating a mechanical switch or a numeric keypad, or setting a start time based on identification of data read by a card reader, and setting a CPU based on a start setting input from this setting means.
1e, the ID determination based on the comparison of the iris data may be started.

Embodiment 5 Also, Biometrics I
In combination with an ID discriminating device other than D, even when the eyes become unmatchable due to illness, if the other ID discrimination is OK, the entire discrimination may be OK. In this case, there is an advantage that the collation can be made faster by first giving a start instruction using an ID discriminating device other than the biometric ID and then discriminating the ID of the eye iris. That is, when registering the collation data, for example, the ID number using the numeric keypad and the feature point data of the iris are stored in the memory as a pair, and at the time of the collation, the ID number is collated first. By collating the registered iris data with the read iris data, there is no need to collate with the iris data of another person, so that the collation time becomes very short.

Embodiment 6 FIG. Alternatively, the iris data of the left and right eyes may be registered, and the iris of the left and right eyes may be collated by the CPU. When the collation of the iris data of the left and right eyes is NG, one of the left and right eyes can be compared. May be determined based on the comparison of the iris data.

[0023]

As described above, according to the ID discriminating apparatus of the present invention, the eye state change is detected from the image of the eye directed to the camera, and the ID discrimination is started, or the ID discrimination is started. Since the ID discrimination is started in combination with the setting means to be set or other ID discriminating apparatus other than the biometric ID, it is possible to perform quick and reliable ID discrimination only for a person who has a will to perform ID discrimination. ,For this reason,
There is no unnecessary consumption of equipment, and security can be improved.
