Abstract

PROBLEM TO BE SOLVED: To avoid ringing of a reception tone of a mischievous call by ringing the doorphone call reception tone only when a picked-up image of a video doorphone camera matches with a registered image. SOLUTION: When a call button of a video doorphone 6 is depressed in the case of the night mode selected in the mode selection, for example, a CPU 14 detects the depression to allow an image processing section 19 to receive and process a picked-up image of a camera of the video doorphone 6. In this case the processed image data are compared with image data registered in advance in a memory 20. When the both are coincident, call reception tone ringing processing to ring a doorphone reception tone is conducted by a designated pushbutton telephone set 5 and the doorphone image is displayed on a video monitor 18 simultaneously. When the image from the doorphone 6 is not in matching with the registered image, no call reception tone ringing processing is executed. Thus, even when the call button is depressed at night, whether or not a mischievous call is identified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone device that houses an intercom.

[0002]

2. Description of the Related Art In a key telephone device accommodating an intercom, when a caller operates the intercom by a visitor or the like, a ring tone (ring tone) is sounded to each accommodated key telephone. Then, when any of the key telephones responds to this call, an intercom call is made by the key telephone that responds.

When such an intercom calling operation is performed, as for the ring tone of the key telephone side, it is general that only the telephone set for which an incoming call is designated rings. Note that there is also a device in which the designated telephone rings the door ring tone only at the nighttime when the designated telephone calls the doorphone during the designated time zone. Further, there is also a device which, when a visitor or the like performs an operation for calling a doorphone during absence, sends a message of absence to the doorphone and then records a message of the visitor. Further, in recent years, it has been found that a device has a TV intercom housed therein. When a door caller is operated by a visitor or the like in such a device, the device side detects this and displays the image of the visitor on the TV monitor. By doing so, it is possible to confirm who the visitor is.

[0004]

However, even if a doorphone calling operation is performed at night, the door ring tone sounds on the telephone side as described above. I can't tell if it was operated by a visitor. Therefore, there is a problem that it is necessary to confirm whether the confirmation is performed on the TV monitor or in response to the incoming call of the intercom. Also, with devices that record messages such as visitors when you are away,
A message indicating the absence will be notified to a third party, which is not preferable for crime prevention. Therefore, an object of the present invention is to prevent ringing of the intercom ring tone due to mischief and to improve the intercom ringing at the time of absence.

[0005]

In order to solve such a problem, the present invention provides an image memory in which image data is registered in advance and an image taken by a camera of a TV doorphone when a calling operation is performed on the TV doorphone. Comparing means for comparing the matched image data with the image data registered in the image memory, and ringing tone ringing means for ringing the intercom ringing tone according to the matching output of the comparing means are provided. Therefore, when a call is made from the TV doorphone,
Since the intercom ring tone sounds only when the image data from the camera matches the pre-registered image data, it is possible to avoid ringing the intercom ring tone due to mischief. Further, the comparison means compares the image data from the camera with the image data in the image memory when a calling operation is performed on the TV door phone in the predetermined mode. Therefore, when a predetermined mode such as the night mode is set, it is possible to avoid the annoying situation that the intercom ring tone sounds by mischief.

Further, there is provided a television monitor for displaying an image taken by the camera, and an image registration means for registering the image being displayed on the television monitor in the image memory based on a predetermined key operation. Therefore, since the image taken by the camera is registered in the image memory, when comparing the registered image with the image from the camera, the images taken by the same camera are compared with each other, so that the accuracy is high. The comparison result can be obtained, and the image data can be registered with a simple configuration. Further, a voice recording / playback unit for registering a voice message is provided, and when the calling operation is performed on the TV intercom in the absence mode, the comparison means outputs the coincidence between the image data from the camera and the image data in the image memory. Then, the voice message of the voice recording / playback unit is played back and sent to the TV intercom. Therefore, if there is a call to the intercom during absence, a message will be output only to a limited number of visitors whose image from the camera matches the registered image. Therefore, it is possible to prevent crimes such as theft while away.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 3 is a block diagram showing the configuration of a key telephone device to which the present invention is applied. In the figure, reference numeral 1 is a main device, and a plurality of outside lines 31 to 3n are connected to the main device 1 and a plurality of key telephones (slave devices) 51 to 5m are connected via respective lines 41 to 4m. ing. A TV door phone 6 having a built-in camera and having a call function is also connected to the main device 1.

Here, the main device 1 is constructed as follows. That is, 111 to 11n are external line interfaces that are interfaces with the external lines 31 to 3n, 12 is a call path switch, 131 to 13m are telephone interfaces that are interfaces with the key telephones 51 to 5m, and 14 is the entire button telephone device. CPU to control, 15 is CPU1
ROM for storing the program executed by 4 and 16 for the temporary storage of data.

Further, 17 is a holding IC for sending a holding melody to the outside line when the outside line is held, and 18 is a TV intercom 6
A TV monitor for displaying the image signal from the TV, an image processing unit 19 for processing the image signal of the TV doorphone 6, an image memory 20 for storing the processed image data, and a voice recording 21 for recording and reproducing a voice message. It is a playback unit. It should be noted that the key telephone 5 includes a communication circuit 51 and a main unit 1.
And a transmission circuit 54 for performing data transmission, a control unit 55 for controlling the key telephone 5, a display circuit 56, and a keyboard 5.
7 and the like.

By the way, in such a key telephone device accommodating such a TV doorphone 6, when a call button of the doorphone 6 is operated by a visitor or the like to make a doorphone call, a visitor is displayed by a TV monitor 18 provided in the device. You can monitor who you are. However, when the call button of the intercom is operated at nighttime and the door ring tone sounds at each key telephone, it is not possible to discriminate whether it was performed by mischief or an emergency visitor. Therefore, in such a case, there is a problem that a troublesome confirmation action is required, which is to confirm on the television monitor 18 or in response to an incoming call from the intercom. For this reason, in the present invention, at night, control is performed so as not to ring the door ring tone for annoying and unnecessary door phone calls caused by mischief.

FIG. 1 is a flow chart showing the operation of the main part of the present invention. That is, when a call button (not shown) of the TV door phone 6 is pressed, the CPU 14 detects this and determines that there is a door incoming call in step S1 as "Y". In this case, when the CPU 14 detects the setting status of a mode switch (not shown) and determines that the time when the incoming call is detected is daytime, the CPU 14 receives a door incoming call for each button telephone set to have the ringing tone of the door specified in advance. Door ringing sound ringing processing for ringing a sound is executed (step S3). And
In this case, the CPU 14 causes the image processing unit 19 to process the intercom image captured by the camera provided in the television intercom 6 and displays the intercom image on the television monitor 18 (step S).
4).

Further, when the incoming call of the intercom is detected at night, the night mode is set by the mode switch described above, and the CPU 14 detects this and determines the "night mode" at step S2 to be "Y". , CPU1
The image processing unit 19 receives and processes the image captured by the camera of the TV door phone 6 (step S4).
5) Then, a comparison process is performed between the processed image data and the image data registered in advance in the image memory 20 (step S6). Then, when this image matches the registered one and the judgment in step S7 becomes "Y", the above-mentioned door ringing sound ringing process for ringing the door ringing sound to each button telephone set to be designated in advance is executed ( At the same time as step S8), the intercom image is displayed on the television monitor 18 (step S4). If the image from the intercom 6 does not match the registered one, the door ringing sound ringing process is not performed.

Next, after the key telephone 5 is off hooked, the keyboard 57 is operated and these operation data are transmitted to the main unit 1 side via the transmission circuit 54, and the CPU 14 transmits the operation data. The data is received via the corresponding telephone interface 13, and it is determined that "there is key operation" in step S9 is "Y". Here, when this operation data indicates an image registration operation and the determination in step S11 is "Y", at this time, the camera of the TV intercom 6 has taken an image, and this taken image is being displayed on the TV monitor 18, and If the determination in S12 is "Y", the CPU 14 causes the image displayed on the television monitor 18 to be registered in the image memory 20 as image data (step S13). The image data registered in the image memory 20 is newly added to the intercom 6 when the intercom 6 receives an incoming call.
The image sent from the device is compared with the comparison process of step S6 described above, and it is determined whether or not the ringing tone of the door is sounded.

On the other hand, at the time when the operation data is sent from the key telephone 5, the door ring tone is ringing in each key telephone, and the operation data indicates the intercom arrival response (that is, in step S10). If "Y"),
The CPU 14 controls the call path switch 12 to capture the intercom that connects the call path between the button telephone and the TV intercom 6 (step S15). Further, when capturing the intercom, the control data is transmitted to each button telephone that is ringing the ringtone to stop ringing the ringtone. In this way, the intercom call by the key telephone is performed.

After that, when the end of the intercom is detected by the on-hook of the button telephone, the communication path switch 12
To disconnect the call path between the button telephone and the TV intercom 6 by opening the intercom (step S1).
7) And the display timer for a predetermined time is started (step S18). Then, when the predetermined time elapses and the time-up of the display timer is detected, step S1
When the determination of 9 is "Y", the image displayed on the television monitor 18 is erased (step S20). In this way, when an incoming call to the intercom is detected at night, the image sent from the TV intercom 6 is compared with the registered image, and the ringtone sounds only when the registered image matches. By doing so, it is possible to avoid a situation in which a door ring tone sounds due to mischief.

The present telephone device that accommodates such a TV door phone 6 has a voice recording / reproducing unit 21 so that the message recording / reproducing unit 2 can record a message of a customer who has visited during absence.
You can also record to 1. However, in such a device, if a caller button of the TV intercom 6 is pressed while there is a visitor during absence, a voice message indicating absence is sent from the intercom 6 to the outside to prevent crime. There is a problem that it is not preferable. FIG. 2 is a flow chart showing an example of a process upon arrival of an intercom which improves the above-described problems upon arrival of the intercom. Here, the same operations as those in the flowchart of FIG. 1 are designated by the same reference numerals, and detailed description thereof will be omitted.

That is, when a door incoming call is detected and "Y" is determined in step S1, it is determined in step S31 whether or not the absence mode is set. Here, if the answering mode is set, the reception of the image data from the TV doorphone 6 (step S5), the comparison processing between the received image and the registered image data (step S6), and the registered image, which have been already described, are performed. A match determination process (step S7) is performed. Here, if the image received from the doorphone 6 and the registered image in the image memory 20 match, then in step S32, it is determined whether or not there is a message recorded in advance in the voice recording / playback unit 21. If the message is recorded, the message is reproduced, and the CPU 14 controls the communication path switch 12 to connect the path between the voice recording / reproducing unit 21 and the TV door phone 6. Then, the reproduced message is transmitted to the intercom 6 through this path in step S33. If the absence mode is not set at the time when the incoming call is detected, the incoming call ringing process is performed (step S3), and the intercom image is displayed on the television monitor 18 (step S4).

Next, when a message to be sent to the TV intercom 6 is recorded in the voice recording / playback unit 21, it is performed as follows. That is, when the key telephone 5 goes off-hook, and the keyboard 57 is subsequently operated to transmit these operation data, “Y” is set in “with key operation” in step S9. If the operation data indicates message recording, "message recording" in step S34 is determined to be "Y". In this case, CPU1
A recording unit 4 controls the call path switch 12 to connect the corresponding telephone 5 and the voice recording / playback unit 31 to record the voice signal sent from the transmitter of the corresponding button telephone 5 in the voice recording / playback unit 21. The process is executed in step S35. In this way, the voice recording / playback unit 21 is provided with the TV doorphone 6 when not in the house.
The voice message sent to is recorded.

When the operation data from the key telephone 5 indicates an image registration operation, it is confirmed that the image taken by the camera of the TV intercom 6 is being displayed on the TV monitor 18. It is registered in the memory 20 (steps S12 and S13). If the operation data from the key telephone 5 indicates a door arrival response, the intercom capture is performed and the call with the intercom 6 side is started (step S15). After that, when the talk with the intercom 6 is detected, the intercom is opened (step S17),
The display timer is started (step S18). After that, when this timer times out, the intercom image displayed on the television monitor 18 is erased (step S
20).

As described above, when the intercom is called during the absence, the message is sent to the intercom 6 only when the image sent from the TV monitor 6 and the registered partner image match. It is not transmitted to the third party, and the message can be sent only to the necessary visitors. By recording a voice message for each visitor in the voice recording / playback unit 21, it is possible to send a unique message to each visitor when he / she is away. In addition, although an example of the key telephone device has been described in the present embodiment, the same effect can be obtained even when the TV door phone 6 and the voice recording / reproducing unit 21 are provided in a general telephone such as a single telephone.

[0021]

As described above, according to the present invention, when the calling operation is performed on the TV intercom, the image data taken by the camera of the TV intercom and the image data registered in the image memory are matched. By comparison, the intercom ringtone is set to ring when a match is detected, so that ringing of the intercom ringtone due to mischief can be avoided. In addition, when the calling operation is performed on the TV doorphone in the predetermined mode, the image data from the camera and the image data in the image memory are compared for coincidence, so that, for example, at night, an intercom ring tone sounds by mischief. Such annoying situation can be avoided in advance.

Further, since the image taken by the camera is registered in the image memory, when comparing the registered image with the image from the camera, the images taken by the same camera are compared with each other. An accurate comparison result can be obtained, and image data can be registered with a simple configuration. Also, when a match is detected between the image data from the camera and the image data in the image memory when a call operation is performed on the TV doorphone in the absence mode, the registered voice message is played and output. As a result, a voice message is sent only to the necessary visitors during absence, so there is no need to inadvertently inform the third party that there is no absence, and thus a crime such as theft while away. Can be prevented.
