Description

  The present invention relates to an interphone device, and more particularly to an interphone device having a function of storing a visitor's video and audio.

  2. Description of the Related Art Conventionally, there is an intercom device having a function of storing a visitor's video and audio. For example, with an intercom device equipped with an answering machine, if there is a visitor at the time of absence, the visitor's camera captures the visitor's image, saves the video, and continues to send a message prompting the visitor to record the message. A sound was reported from the front door machine, and then a visitor voice was recorded and a second recording was performed (for example, see Patent Document 1).

JP 2007-267253 A

The above intercom device, which has a function to record a visitor's message, sounds a message that prompts the recording of the message by recording the video captured by the camera before and after the message that prompts the recording of the message. I was able to leave a video of the visitor even for the visitor who went home without recording.
However, when recording the video before and after the sound of the message prompting the recording, the recording is performed twice for one call operation, and the recording area for two normal recording operations is used on the memory. It was. For this reason, the memory usually has a capacity capable of recording about 30 records. However, when the absence recording is set, the number of records that can be recorded is about half, which is about 15 records, and the memory capacity cannot be fully utilized.

  Therefore, in view of such problems, the present invention can efficiently use the memory by saving only one video by saving one call operation even if the answering function is turned on, and in that case, a lot of information about the visitor is obtained. An object of the present invention is to provide an intercom device capable of leaving a video including the same.

In order to solve the above-mentioned problem, the invention of claim 1 has an entrance cordless device for a visitor to call a resident, and a living room master phone for a resident to respond to a call from the entrance cordless device. The entrance cordless handset is equipped with a camera for imaging the visitor, while the living room master unit is equipped with a monitor for displaying the captured image of the camera. An interphone device having an answering machine function for storing audio, wherein the parent device stores a message for prompting a visitor to record a message, and stores a video and audio, and video and audio A storage control unit that controls the storage of the voice, and a voice detection unit that determines whether or not there is a voice. The storage control unit activates the camera when the answering machine function is turned on and the entrance unit is called. Take a memo as a first video for a certain period of time After recording the message prompting the recording from the entrance cordless handset, the sound information collected by the entrance cordless handset for a certain period of time is saved in the memory, and the camera image is linked with the saving of the sound information. The video is stored in the memory as a second moving image, and the storage control unit deletes the first moving image when the sound detection unit determines that there is sound in the stored sound information, and the sound is stored in the stored sound information. If it is determined that there is not, the second moving image is erased.
According to this configuration, both the first moving image before the message reporting sound and the second moving image after the reporting sound are first saved, but since one is finally deleted, the conventional moving image is not increased without increasing the memory capacity. Two times as many visitor images can be saved, and the memory can be used effectively. Since the second video remains when the visitor's voice is stored, it is possible to grasp the requirements in addition to the visitor's video, and leave a video containing a lot of information about the information visitor.

The invention of claim 2 has an entrance cordless handset for a visitor to call a resident, and a living room base phone for the resident to respond to a call from the entrance cordless handset. While the room master unit is equipped with a monitor that displays the image captured by the camera, the room master unit also has an answering function that stores the video and audio of the visitor when a call operation is received. The intercom apparatus includes a room master unit that stores a message for prompting a visitor to record a message, stores a video and audio, and a storage control unit that controls video and audio storage And a person detection unit that determines the presence / absence of a person from the video, and the storage control unit activates the camera and captures a captured video for a predetermined time when the answering machine is called and the answering machine function is on. Save it in memory as the first video After sounding the message prompting the recording from the entrance cordless handset, the sound information collected by the entrance cordless handset for a certain period of time is saved in the memory, and the captured image of the camera is stored in the memory in conjunction with the saving of the sound information. The saving control unit deletes the first moving image when the person detecting unit detects the presence of a person in the second moving image, and stores the first moving image if the second moving image does not detect the presence of a person. The second moving image is erased.
According to this configuration, both the first moving image before the message reporting sound and the second moving image after the reporting sound are first saved, but since one is finally deleted, the conventional moving image is not increased without increasing the memory capacity. Two times as many visitor images can be saved, and the memory can be used effectively. When the presence of a person is detected in the second video, the second video remains, so that it is possible to listen to the recorded audio in addition to the visitor video, leaving a video that can be judged to contain a lot of information about the visitor. be able to.

According to a third aspect of the present invention, in the configuration according to the first or second aspect, the storage control unit separately stores the first image of the first moving image as a still image in a memory.
According to this configuration, since still images are also stored, it is possible to confirm visitors with images even if the moving image is deleted. Further, since a still image is extracted from a part of the moving image, it is not necessary to start a separate camera for the still image.

According to a fourth aspect of the present invention, in the configuration according to the third aspect, the storage control unit starts recording the first moving image after a few seconds have elapsed after receiving the call operation.
According to this configuration, since the visitor often does not reach the camera immediately after receiving the call operation, for example, the recording of the captured image of the camera is started with a slight delay after receiving the call operation. By doing so, it is easy to obtain an image in which a visitor is reflected even in a still image, which is effective in confirming the visitor.

  According to the present invention, both the first moving image before the message reporting sound and the second moving image after the reporting sound are first saved, but one is finally deleted, so that the conventional moving image is not increased without increasing the memory capacity. Two times as many visitor images can be saved, and the memory can be used effectively. Then, when a voice message is left, or when a person can be confirmed in the second video, the second video is left, so that it is possible to leave a video that can be determined to contain a lot of information about visitors.

It is a block diagram which shows an example of the intercom apparatus which concerns on this invention. FIG. 10 is a timing chart showing a flow of storing video / audio after receiving a call operation. It is a block diagram of the room master which shows the other form of an intercom apparatus.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention are described in detail below with reference to the drawings. FIG. 1 is a block diagram showing an example of an intercom device according to the present invention, where 1 is an entrance handset for a visitor to call a resident, and 2 is for a resident to respond to a call from the entrance handset 1 It is a parent machine. Both are connected by a transmission line L1.

  The entrance child device 1 communicates with a call button 11 for performing a call operation, a child device acoustic control unit 14 having a microphone 12 and a speaker 13 for making a call, a child device camera 15 for imaging a visitor, and a room parent device 2. For example, a handset IF16 and the like.

  The main room 2 displays a call button 21 for responding to a call from the front door 1, a parent sound control unit 24 including a microphone 22 and a speaker 23 for calling, and a captured image of the handset camera 15. Monitor 25, video processing unit 26 for processing video displayed on the monitor 25, voice mail button 27 for turning on the voice mail function, memory 28 for storing video and voice, and message storage for storing predetermined message voice Unit 29, a playback button 30 for performing a playback operation of stored video, a master unit CPU 31 for controlling the living room master unit 2, a master unit IF 32 for communicating with the entrance slave unit 1, a voice detection unit 33 for determining the presence or absence of voice, and the like. .

The intercom apparatus configured as described above operates as follows. First, the operation at the normal time when the answering machine is not set (when the answering function is off) will be described.
When the call button 11 of the entrance cordless handset 1 is pressed and the call is made, a ringing sound is emitted from the speaker 23 of the room base phone 2 under the control of the base phone CPU 31 and the handset camera 15 starts imaging. The captured image is displayed on the monitor 25. When the call button 21 is pressed by the resident who notices the visitor by the ringing tone while confirming the visitor by looking at the display image on the monitor 25, the call path between the entrance cordless handset 1 and the living room base phone 2. Is formed, and a call can be made between the visitor and the resident.

The master unit CPU 31 performs storage control of the captured video of the slave unit camera 15. FIG. 2 is a timing chart showing a flow of storing video / audio after receiving a call operation, and will be described with reference to FIG. Specifically, among the captured images of the slave camera 15 that has started imaging in response to the call operation, the storage of the image is started when 2 seconds have elapsed since the call operation was received, and for a certain time (for example, 10 seconds). Are stored in the memory 28 (first moving image M1). However, if the call ends before the fixed time elapses (when the end-of-call operation is performed), the video storage ends at that point.
Further, the first image frame of the stored first moving image M1 is separately stored in the memory 28 as a still image P1.

Next, the operation when the answering machine setting is made and the answering machine function is turned on will be described. When the answering machine button 27 of the base room 2 is pressed, the answering function is turned on to start the answering mode operation, which operates as follows.
When the call button 11 of the entrance cordless handset 1 is pressed and a call is made, a ringing sound is emitted from the living room base phone 2 under the control of the base phone CPU 31, and at the same time, the handset camera 15 starts to pick up an image. The displayed video is displayed on the monitor 25.
Then, among the captured images of the slave camera 15 that has started imaging in response to the call operation, the storage of the image is started when 2 seconds have elapsed since the call operation was received, and the video (for example, 10 seconds) ( The first moving image M1) is stored (temporarily stored) in the memory 28. Further, the first image frame of the stored first moving image M1 is separately stored in the memory 28 as a still image P1.

Up to this point, the operation is the same as when the answering machine function is off, but the following operation is further performed under the control of the master CPU 31.
Thereafter, when the storage of the first moving image M1 is completed after a certain time has elapsed, the voice message V1 stored in the message storage unit 29 is notified from the entrance cordless handset 1 to prompt recording of the next message. Is done. For example, the message “I can't get out right now. Please give me a message” is emitted from the entrance cordless handset 1.

Then, when this reporting sound is finished, the storage V2 of the visitor voice collected by the microphone 12 of the entrance cordless handset 1 is started, recorded V2 for a certain time (here 15 seconds), and stored in the memory 28.
Further, in conjunction with the storage of the sound, the captured image (second moving image M2) of the handset camera 15 is also stored (temporarily stored) in the memory 28.
However, the voice detection unit 33 is activated in accordance with the voice storage, and it is determined whether or not there is a voice in the saved sound, and the target of the main saving is determined according to the presence or absence of the voice. In other words, if it is determined that there is a sound in the recorded sound, the second moving image M2 is permanently stored together with the still image P1, and the first moving image M1 is deleted.
If it is determined that there is no sound, the first moving image M1 is stored together with the still image P1, and the second moving image M2 and the stored sound V2 are deleted.

As described above, both the first moving image M1 before the message reporting sound and the second moving image M2 after the reporting sound are first saved, but since one of them is finally deleted, the capacity of the memory 28 is not increased. It is possible to store a visitor video twice that of the prior art and to effectively use the memory 28. When the visitor's voice is stored, the second video M2 remains, so that the visitor's requirements can be grasped. On the other hand, if the voice cannot be confirmed, the second moving image is deleted because the second moving image M2 is considered not to be captured because the visitor returns. Therefore, it is possible to leave an image including a lot of information about visitors.
Further, since the still image P1 is also saved, it is possible to confirm the visitor with the image even if the moving image is deleted. And since the still image P1 is extracted from a part of a moving image, it is not necessary to start the subunit | mobile_unit camera 15 separately for the still image P1.
Further, since the visitor often does not reach the handset camera 15 immediately after receiving the call operation, for example, the recording of the captured image of the handset camera 15 is slightly delayed after receiving the call operation. By starting this, it is easy to obtain an image in which the visitor is reflected even in the still image P1, and it is effective for confirming the visitor.

  FIG. 3 shows another embodiment of the intercom device, and shows a block diagram of the living room master unit 2. The room master unit 2 shown in FIG. 1 is different in that the voice detection unit 33 is not provided and a person detection unit 34 is provided instead. Since the other components including the configuration of the entrance cordless handset 1 are common, description thereof will be omitted and the operation will be described below. It should be noted that the person detection unit 34 has a function of detecting a person (particularly a face) in a video image taken by the handset camera 15.

Since the storage operation of the still image P1, the first moving image M1, the sound V2, and the second moving image M2 is the same as the flow shown in FIG. 2, the description is omitted, and the stored moving image is selected as follows.
The person detection unit 34 is activated in accordance with the storage control of the second moving image M2, and it is determined whether or not a person is included in the stored video, and the target of the main storage is determined according to the presence or absence of the person. If it is determined that there is a person in the second moving image M2, the second moving image M2 is stored together with the still image P1, and the first moving image M1 is deleted.
On the other hand, if it is determined that there is no person in the second moving image M2, the first moving image M1 is stored together with the still image P1, and the second moving image M2 and the stored audio V2 are deleted.

In this way, if the presence of a person is detected in the second video M2, the second video M2 may be left without confirming the presence or absence of sound, and the first video M1 may be erased. If it remains, it can be seen that the act of recording the message is being performed, and it is possible to listen to the recorded audio in addition to the video. On the other hand, if it is not possible to confirm the presence of a person in the second video, it can be determined that there is no recording of the business, so leaving the first video leaves a video that can be determined to contain a lot of information about visitors. it can.
Then, both the first moving image M1 before the message reporting sound and the second moving image M2 after the reporting sound are first saved, but since one of them is eventually deleted, the conventional video without increasing the capacity of the memory 28 is stored. Two times as many visitor videos can be stored, and the memory 28 can be used effectively.

In the above embodiment, the recording time of the first moving image M1 is 10 seconds and the recording time of the second moving image M2 is 15 seconds. However, the recording time of the video to be stored is arbitrary, and a call operation is performed. The waiting time until the still image is recorded is not fixed at 2 seconds, but may be set to several seconds between 1 second and 4 seconds.
Moreover, the intercom device of the present invention can be applied to a detached house, but can also be applied to an apartment house, and the above-mentioned collective entrance machine (not shown) installed at the entrance for selecting and calling a dwelling unit is described above. The entrance slave unit 1 may be used, and the above control can be performed between the collective entrance unit and the room master unit 2 installed in each dwelling unit.
