[0018]
<Forwarding when you are away>
When the call switch 41 is turned on by the visitor in the above-described ready state, the control shown in the flowchart (absence routine) in FIG. 6 is executed. First, in step S41, a personal identification check is performed. That is, as shown in the flowchart of FIG. 7, first, the feature extraction unit 33 extracts a feature portion from the one-shot actual image acquired from the real image temporary acquisition memory 29 (steps S51 and S52). In step S54 to 56, it is determined whether or not they match the feature data as external personal information read from the feature storage area 25C. These steps are executed in the order of the pointer addresses until the feature portions match or there is no feature data stored in the feature storage area 25C. If they match, “YES” is set, and a match flag is set (step S57).
Next, as shown in the answering routine of FIG. 6, if the feature part matches (there is a match flag set) and there is a corresponding phone number data, “YES” is determined in step S42, and the resident's phone number is set at that phone number. A call to the mobile phone 52 is started (step S43), and a message indicating that the call is being made is reproduced on the speaker 44 of the slave unit 40 (step S44). Here, if there is a response from the mobile phone 52 in step S45, “YES” is given, and the mobile phone 40 and the mobile phone 52 can talk until the mobile phone 52 is on-hooked (steps S47, 49). ). On the other hand, if the feature part does not match in step S42 (no match flag is set), or if the phone number is not registered even if they match, or if a call is made but no response is received in step S45, A message for requesting a message is reproduced from the speaker 44 of the handset 40 (step S46). Thereafter, in step S48, the control shown in the flowchart of FIG. 8 (answering machine recording routine) is executed. First, in step S61, the recording / recording timer starts counting. Next, in step S62, only when the above-described match flag is set, the image data and audio data from the camera 42 and microphone 43 of the slave unit 40 are associated with the pointer address corresponding to the matched feature data. (Step S63). Next, the image data and the sound data are stored in the absence image storage area 25A and the absence sound storage area 25B of the storage unit 25, respectively (step S64). On the other hand, if there is no set match flag, it is stored without being associated. The storage (recording / recording) ends after a certain period of time (steps S65 and S66). Therefore, even if it is a mobile phone that does not respond even if it is called and does not have an answering machine function, the intercom 10 of this embodiment can record the message of the visitor.
[0019]
<Reproduction of visitor's image and sound>
When the resident returns home and wants to confirm the message of the absent visitor who could not talk directly or the message of that person, the absence / home switching switch 21 is first returned to the home side and the playback switch 24 is turned on. Then, the control shown in the flowchart (reproduction routine) of FIG. 9 is executed. First, in step S71, it is identified whether there is image data or audio data corresponding to the pointer address in the absence image storage area 25A or absence voice storage area 25B. If there is, the pointer address NO, name, and presence / absence of recording are displayed in a list format on the display 26 (step S72). Next, in step S73, an image and sound corresponding to the pointer address NO selected by the resident with the key input device 27 are reproduced from the display 26 and the speaker of the handset 28 (step S74). If the resident turns on the end key in step S75, the process goes to step S76 (step S75). In step S76, if there is image data or voice data not associated with the pointer address in the absence image storage area 25A or absence voice storage area 25B, it is reproduced on the display 26 and the speaker 44 (step S77). Therefore, with the intercom 10 according to the present embodiment, it is possible to confirm those who have not been able to directly communicate with the residents who are away from home while they are away.
[0020]
Thus, according to the intercom 10 of the present embodiment, when going out, the telephone number of the resident's mobile phone 52 is stored in the external personal information (feature data, name, etc.) stored in the feature storage area 25C of the storage unit 25. ) Can be recorded. Then, when a visitor is identified by comparing the feature extracted from the video of the away visitor and the feature as the external personal information, a call is made with the telephone number associated with the visitor. A call can be made between the handset 40 and the mobile phone 52. Therefore, the resident can record the telephone number of his / her mobile phone in association with the specific visitor, and can directly talk with the specific visitor when he / she is away from home. Also, even if the visitor was unable to make a direct call, the image and sound of the visitor registered with the external personal information can be recorded / reproduced corresponding to the visitor, so the resident can , It is possible to easily confirm the requirements of the person associated with the visitor.
