  When the user selects “Register” on the menu screen displayed on the base unit side display unit 13 (step S201), the base unit side control unit 11 stores a plurality of sheets stored in the base unit side storage unit 16. Recorded images are read out, and these recorded images are displayed on the base unit side display unit 13. The user selects a comparison image suitable for face authentication, that is, a comparison image including a visitor's face from among a plurality of recorded images displayed on the parent device side display unit 13 (step S202). . Thereafter, the user selects “image transfer” in order to transfer the selected comparison image to the face authentication system 6 (step S203).

  The parent device side control unit 11 creates a communication signal including the comparison image selected by the user and the address of the interphone parent device 1, and transmits the communication signal from the parent device side communication unit 12 to the face authentication system 6 ( Step S204). The communication signal is transmitted to the face authentication system 6 via the control device 3 and the intercom slave unit 2, but the address included in the communication signal is converted from the address to the dwelling unit number (room number) in the control device 3. Is done.

  In the face authentication system 6, the control unit 61 causes the registration unit 63 to register the comparison image data (comparison data) included in the communication signal received by the communication unit 62 (step S205). In other words, the registration unit 63 stores the comparison data in the storage unit 64 in association with the dwelling unit number. When the registration of the comparison data is completed, the control unit 61 generates a communication signal including a registration completion notification and a dwelling unit number to notify that the registration is completed, and transmits the communication signal from the communication unit 62 to the interphone master unit 1. (Step S206). The dwelling unit number included in the communication signal is converted into the address of the intercom base unit 1 in the control device 3.

  In intercom base unit 1, base unit side control unit 11 registers a comparison image (comparison data) in face authentication system 6 based on a registration completion notification included in the communication signal received by base unit side communication unit 12. This is confirmed (step S207). Then, the base-side controller 11 ends the comparison image registration operation (step S208).

  Incidentally, it is preferable that the recording unit 14 is configured to record the first image, the second image, and the third image as the recorded images. The first image is an image acquired by the acquisition unit 23 before calling from the intercom handset 2, for example, an image from when a visitor is detected by a human sensor until the visitor presses the “call” button. is there. The second image is an image that is acquired by the acquisition unit 23 during a call from the intercom handset 2, and is an image from when the visitor presses the “call” button until the resident presses the “call” button. The third image is an image acquired by the acquisition unit 23 during a call between the interphone master unit 1 and the interphone slave unit 2, and is an image from the start of the call between the interphone master unit 1 and the interphone slave unit 2 to the end of the call. . In this case, the resident may select a comparison image from the first image, the second image, and the third image, or may compare the image from any one of the first image, the second image, and the third image. An image for use may be selected.
