っている。Next, the operation will be explained. The light from the fluorescent lamp 3a is passed through the diffuser-transmitting plate 4 so that the brightness on its surface is uniform.
put The light from the fluorescent lamp 3a is blocked in the area where the hand 1 is placed, and only the light that is transmitted without being blocked by the hand 1 is input to the video camera 5. That is, the shape of the hand is input to the video camera 5 as a contrast image in which the part where the hand 1 is placed is black and the part where the hand 1 is not placed is white. The contrast image of the shape of the hand 1 inputted to the video camera 5 is processed by the image input processing unit 6, and is processed as parameters such as finger length and flatness in correspondence with the ID number inputted from the tenki 9. It is stored in the memory section 8. Next, after memorizing the shape parameters of hand 1, switch the selector switch 7 to the B side, input the ID number using the ten key 9,
Place hand 1 on the top of lighting device 2 again. As described above, contrast images of 1,000 shapes are input to the video camera 5 again, and the image input processing section 6 obtains parameters such as finger length and flattening. A determination processing section 10 compares the obtained parameters with parameters previously stored in a memory section 8 corresponding to the ID number, and outputs the result as a determination output signal 11 for personal identification. Further, the sensitivity characteristics of the solid-state image sensor of the video camera 5 are generally approximately smooth in the wavelength range of 400 to 9QQnm, as shown in FIG.

ものである。Further, a personal identification device similar to the above personal identification device was published in the Nikkei Sangyo Shimbun, February 8, 1985, page 8. This uses the hand print and the ID card (D card) to instantly identify the person and control the opening and closing of the door.

得にくくなるなどの問題点があった。Since the conventional personal identification device is configured as described above, due to the influence of the light reflected from the hand 1 by the external indoor light 14, coupled with the sensitivity characteristics of the solid-state image sensor of the video camera 5, the dotted line in FIG. As shown in , the difference between the camera output voltage due to flat reflected light and the video camera output voltage at the area where hands are not placed becomes small, making it difficult to obtain a black and white contrast image.

After memorizing the hand shape parameters, the selector switch 7 is switched to the B side, the ID number is inputted from the numeric keypad 9, and the hand 1 is placed on the top surface of the lighting device 2 again. As mentioned above, a contrast image of 1,010 shapes is inputted to the video camera 5, and the image input processing unit 6 extracts parameters such as finger length and notebook, and stores them in advance in memory corresponding to the parameters and ID number. The judgment processing section 10 compares the parameters stored in the section 8 with the parameters stored in the section 8, and outputs the result as a judgment output signal 11 to perform personal identification.
