The eye image in FIG. 4B represents an eye image in which a line of sight is directed to a visitor recognized as being in front of the front door 20.

  The analysis processing in the video processing unit 301 of the living room base unit 30 is continuously performed. Thereby, the position of the visitor at the time of each analysis, that is, the movement of the visitor around the entrance terminal 20 is recognized. Based on the analysis result of the video processing unit 301, the living room base unit CPU 310 sequentially selects eye images having a line of sight corresponding to the position where the visitor is present from the image storage unit 303.

  The eye images selected from the image storage unit 303 are sequentially transmitted from the living room master unit 30 to the entrance slave unit 20. As a result, the eye image of the line of sight following the position (visitor movement) of the visitor is sequentially displayed on the entrance display unit 207 (see FIGS. 4C and 4D). The eye image in FIG. 4C represents an eye image in which the line of sight is directed to a visitor recognized as being on the right side of the entrance cordless handset 20.

Such a wide-open eye image may be changed to an eye image (an example of an eye image that gives high alertness) as shown in FIG. Moreover, when 20 seconds have passed since detection, the eyes may be further narrowed to change to an eye image that looks at the visitor (an example of an eye image that gives higher alertness) as shown in FIG. In such a case, for example, a message “Recording” 221 as shown in FIG. 6 may be displayed on the entrance display unit 207 together with the eye image.

  In addition, the occupant may operate a predetermined button provided on the operation unit 304 of the living room master unit 30 to display the eye images and messages having different facial expressions.

The entrance display unit 207 may display different types of eye images depending on the visitors.
The video processing unit 301 of the living room base unit 30 recognizes the visitor's face captured in the video of the camera 202 to identify the visitor. The room master CPU 310 changes the type of eye image displayed on the entrance display unit 207 according to the identification result of the video processing unit 301.

  For example, when the visitor is identified as an acquaintance, the room master device CPU 310 does not change the facial expression of the eye regardless of the location (movement) of the visitor (acquaintance) and the elapsed time since detection. The eye image with a low alertness shown in FIG. 4B may be continuously displayed on the entrance display unit 207, or an eye image indicating that no alertness is provided.

  Further, the eye image displayed on the entrance display unit 207 may be configured to change according to an electronic pan / tilt operation operated on the operation unit 304 of the living room base unit 30.

  When a resident in the house J performs a pan / tilt operation via the operation unit 304 while confirming a visitor's image displayed on the parent device display unit 302, a control signal including operation information is output from the room parent device CPU 310. Is done. Further, an eye image having a line of sight corresponding to the pan / tilt operation is selected from the image storage unit 303 by the room parent device CPU 310. The control signal and the eye image are transmitted to the entrance cordless handset 20 through the signal line L. Further, the entrance slave unit CPU 210 outputs a control signal for displaying the eye image on the entrance display unit 207. The entrance display unit 207 displays an eye image having a line of sight corresponding to the pan / tilt operation based on the control signal output from the entrance machine CPU 210.

  According to the intercom system 1 configured as described above, for example, an eye image imitating a human eye is displayed on the entrance display unit 207 of the entrance cordless handset 20, and the eye line of the eye image changes so as to follow the movement of the visitor. Therefore, it is possible to give the suspicious visitor the awareness (wariness of caution) seen by others and improve the crime prevention function.

  In addition, since the expression of the eye image can be changed according to the elapsed time since the suspicious visitor was detected, for example, the suspicious visitor waiting around the entrance machine without pressing the call button 203, the call A suspicious visitor or the like who hears the resident's reaction to whether the button 203 is pressed (whether or not he / she is away) can be given a higher awareness of being seen by others.

  Moreover, since a message that raises the alertness of a suspicious visitor can be displayed on the entrance display unit 207 together with an eye image, the suspicious visitor is given a higher awareness of being seen by others. be able to.

  Further, by performing face recognition, it is possible to suppress alertness to the resident acquaintances by stopping the change of the eye image. For this reason, only the suspicious visitor can be given awareness of being viewed by others.
