  Hereinafter, an entrance image output apparatus according to the present invention will be described using embodiments. In the following embodiments, components and steps denoted by the same reference numerals are the same or equivalent, and repetitive description may be omitted.

(Embodiment 1)
The entrance image output apparatus according to Embodiment 1 of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing a configuration of an intercom system according to the present embodiment. In FIG. 1, the intercom system according to the present embodiment includes an entrance image output device 1, an individual entrance camera 2, an indoor terminal 3, an individual entrance terminal 4, and a collective entrance provided in each house of an apartment house. Control of connection between the camera 5 for the entrance hall, the entrance hall terminal 6, the indoor terminal 3 and the entrance hall terminal 6, and control for unlocking the door of the entrance hall according to an instruction from the indoor terminal 3 The control part 7 which performs etc. is provided.

  For convenience of explanation, FIG. 1 shows a case where there are only three houses, namely, A house, B house, and C house in the apartment house, but the apartment house may be an arbitrary number of two or more houses. .

  In addition, this apartment house may be a condominium, a tenant building having tenants such as a plurality of business establishments, or a residential area where a plurality of single-family houses are gathered. As long as it is a collective housing with a collective entrance, any form may be used. As a residential area where a plurality of detached houses are gathered, for example, there is a so-called gated community. When the housing complex is a condominium or a tenant building, the housing entrance is, for example, an entrance that visitors must pass to enter the housing complex, and an intercom that can communicate with each person in the housing complex is provided. In many cases, a visitor can enter the apartment house by unlocking the door at the entrance from the indoor terminal 3 from each door of the apartment house. If the apartment is a gated community, the entrance is the gate of the gated community, and there are intercoms that can communicate with people in each apartment. By unlocking the door at the entrance from the indoor terminal 3 of each apartment house, visitors can enter the grounds of the gated community.

  The intercom system constituted by the indoor terminal 3, the individual entrance terminal 4, the collective entrance terminal 6, and the control unit 7 is the same as the intercom system that has conventionally existed in an apartment house, and a detailed description thereof will be given. Omitted.

  The individual entrance camera 2 is a camera provided so that when a visitor comes to the individual entrance, the face and the whole body of the visitor can be photographed. The collective entrance camera 5 is a camera provided so that when a visitor comes to the collective entrance, the face and whole body of the visitor can be photographed. The individual entrance camera 2 and the collective entrance camera 5 are the same as the monitoring camera used in the conventional intercom system with a monitoring function, the camera used in the monitoring system, and the like, and will be described in detail. Omitted.

  FIG. 2 is a block diagram showing a configuration of the entrance image output apparatus 1 according to the present embodiment. 2, the entrance image output apparatus 1 according to the present embodiment includes a microphone 11, a determination unit 12, a collective entrance image information reception unit 13, an individual entrance image information reception unit 14, a selection unit 15, and an output unit. 16.

  The microphone 11 converts sound into an electric signal. The microphone 11 receives a ringing tone emitted from the interphone indoor terminal 3. Therefore, the microphone 11 is preferably provided at a position within a range where the ringing sound emitted by the indoor terminal 3 can be received.

  The determination unit 12 determines whether the sound received by the microphone 11 is a ringing sound corresponding to the collective entrance from the indoor terminal 3 of the interphone, or a call corresponding to the individual entrance emitted from the indoor terminal 3 of the interphone. It is judged using an electric signal whether it is a sound.

Here, a determination method by the determination unit 12 will be described.
First, it is assumed that the ringing sound corresponding to the collective entrance is different from the ringing sound corresponding to the individual entrance. For example, these ringing sounds may have different timbres. For example, one ringing tone is “ping-pong” and the other ringing tone is “kinkon”. In this case, for example, the determination unit 12 holds in advance sound information indicating a ringing sound corresponding to the collective entrance and sound information indicating a ringing sound corresponding to the individual entrance, and the microphone 11 has a predetermined sound. When the sound signal is received, the electric signal corresponding to the sound is compared with the sound information stored in advance using a technique such as pattern matching, and they match or the similarity is equal to or greater than a predetermined threshold value. It may be determined that the entrance ringing sound corresponding to the sound information is emitted from the indoor terminal 3. The determination unit 12 may perform this process using a known voice recognition technique.

  Further, for example, the ringing sounds may have different sound lengths. For example, one ringing tone is “ping-pong” and the other ringing tone is “ping-pong ping-pong”. In this case, for example, the determination unit 12 holds in advance length information indicating the length of the ringing sound corresponding to the collective entrance and length information indicating the length of the ringing sound corresponding to the individual entrance. When the microphone 11 receives a predetermined sound, the length of the electrical signal corresponding to the sound is compared with the length information held in advance using a technique such as pattern matching, It may be determined that the entrance ringing sound corresponding to the length information whose similarity is equal to or greater than a predetermined threshold is emitted from the indoor terminal 3. In this case as well, it is needless to say that each sound information may be held and judged using the sound information as in the case where the tone color of the ringing tone is different.

  Further, for example, both may have different sound volumes. For example, the other ringing tone may be smaller than the one ringing tone. In this case, for example, the determination unit 12 previously obtains sound level information indicating the level of the ringing sound level corresponding to the collective entrance and sound level information indicating the level of the ringing sound level corresponding to the individual entrance. When the microphone 11 receives a predetermined sound, the amplitude of the electric signal corresponding to the sound is compared with the sound level information stored in advance, and the values match or the degree of similarity is predetermined. It may be determined that the entrance ringing sound corresponding to the sound level information that is equal to or higher than the threshold value is emitted from the indoor terminal 3.

  If it is possible to determine whether the sound received by the microphone 11 is a ringing sound corresponding to the collective entrance or a ringing sound corresponding to the individual entrance by a method other than the above, It goes without saying that the method may be used.

  The collective entrance image information receiving unit 13 receives collective entrance image information that is information indicating an image of a visitor at the collective entrance. This collective entrance image information is information indicating an image taken by the collective entrance camera 5. The collective entrance image information may be a moving image or a still image as long as it is an image that can appropriately confirm a visitor. The data format of the collective entrance image information does not matter. Collective entrance image information may be transmitted, for example, via a dedicated communication line or cable installed in an apartment house, or a cable television (CATV) network or LAN provided in advance. It may be transmitted via the communication line. Note that the collective entrance image information receiving unit 13 may or may not include a receiving device (for example, a modem or a network card) for receiving. The collective entrance image information receiving unit 13 may be realized by hardware, or may be realized by software such as a driver that drives a receiving device.

  The individual entrance image information receiving unit 14 receives individual entrance image information that is information indicating an image of a visitor at the individual entrance. The individual entrance image information is information indicating an image taken by the individual entrance camera 2. The individual entrance image information may be a moving image or a still image as long as the image can appropriately confirm the visitor. The data format of the individual entrance image information is not limited. The individual entrance image information may be transmitted via, for example, a dedicated communication line or cable installed in an apartment house, or via a cable or communication line of a pre-installed interphone system. May be transmitted. Note that the individual entrance image information receiving unit 14 may or may not include a receiving device (for example, a modem or a network card) for receiving. Further, the individual entrance image information receiving unit 14 may be realized by hardware, or may be realized by software such as a driver that drives a receiving device.

  When the determination unit 12 determines that the sound received by the microphone 11 is a ringing sound corresponding to the collective entrance from the indoor terminal 3 of the interphone, the selection unit 15 receives the collective entrance image information reception unit 13. The collected entrance image information is selected. In addition, when the determination unit 12 determines that the voice received by the microphone 11 is a ringing tone corresponding to the individual entrance from the indoor terminal 3 of the interphone, the selection unit 15 receives the individual entrance image information reception unit 14. Selects the individual entrance image information received. For example, the selection unit 15 may perform this selection by switching between the collective entrance image information and the individual entrance image information using a switch or the like.

The output unit 16 outputs an image indicated by the information selected by the selection unit 15 to the display device. The display device is, for example, a CRT or a liquid crystal display. The output may be, for example, passing image data to a display device via a cable or the like, or transmitting image data to a display device via a communication line or the like. Since the output by the output unit 16 is performed after the selection unit 15 selects the information, as a result, the voice received by the microphone 11 is generated from the collective entrance door or the collective entrance terminal 3 in the intercom system of the apartment house. When the determination unit 12 determines that the ringing sound corresponds to the individual entrance, the output by the output unit 16 is performed.
The output unit 16 may or may not include the display device. The output unit 16 may or may not include a device that outputs information to the display device. The output unit 16 may be realized by hardware, or may be realized by software such as a driver that drives these devices. In the present embodiment, it is assumed that the output unit 16 does not include a display device and passes image information to the external display device 21.
Next, the operation of the entrance image output apparatus 1 according to the present embodiment will be described using the flowchart of FIG.

  (Step S <b> 101) The determination unit 12 determines whether sound has been received by the microphone 11. If a sound is received, the process proceeds to step S102. If not, the process of step S101 is repeated until a sound is received. Note that the determination unit 12 may determine this determination based on, for example, that the level of the electric signal from the microphone 11 is no longer 0, or may determine the determination by other methods.

  (Step S <b> 102) The determination unit 12 determines whether the sound received by the microphone 11 is a ringing sound corresponding to the collective entrance. And when it is a ringing tone corresponding to a collective entrance, it progresses to Step S105, and when that is not right, it progresses to Step S103.

  (Step S103) The determination unit 12 determines whether the sound received by the microphone 11 is a ringing tone corresponding to the individual entrance. If the ringing sound corresponds to the individual entrance, the process proceeds to step S104. Otherwise, the sound received by the microphone 11 is not any ringing sound, and the process returns to step S101.

  (Step S <b> 104) The selection unit 15 selects the individual entrance image information received by the individual entrance image information reception unit 14.

  (Step S <b> 105) The selection unit 15 selects the collective entrance image information received by the collective entrance image information receiving unit 13.

(Step S <b> 106) The output unit 16 outputs the image information selected by the selection unit 15 to the display device 21. Then, the process returns to step S101. Note that the output of the image information to the display device 21 may end, for example, when a predetermined time (for example, 1 minute) elapses, and an instruction from the user (for example, the user presses the end button) Or the like, or may be terminated with another event as a trigger.
In the flowchart of FIG. 3, the process ends when the power is turned off or the process is terminated.

  In the flowchart of FIG. 3, first, it is determined whether or not the sound received by the microphone 11 is a ringing tone. If it is determined that the sound is a ringing tone, whether the ringing sound corresponds to the collective entrance. It may be determined whether it corresponds to an individual entrance.

  Next, the operation of the entrance image output apparatus 1 according to the present embodiment will be described using a specific example. In this specific example, the operation of the intercom system will be described.

  In this specific example, as shown in FIG. 4, the determination unit 12 is “sound information 001” that is information indicating the ringing sound corresponding to the collective entrance, and information that is indicating the ringing sound corresponding to the individual entrance. It is assumed that “sound information 002” is held. These pieces of information are used for pattern matching with the ringing tone.

  In this specific example, it is assumed that the ringing sound corresponding to the collective entrance is “ping-pong” and the ringing sound corresponding to the individual entrance is “kinkon”.

  First, suppose that Mr. ABC came to the entrance of the apartment house of A's house as shown in FIG. 5 in order to visit A's house. Mr. ABC operates the collective entrance terminal 6 to input the number corresponding to the house A and presses the call button. Then, a ringing tone “ping-pong” corresponding to the collective entrance is emitted from the indoor terminal 3 of the A house.

  The microphone 11 receives the ringing sound “ping-pong” and converts it into an electrical signal (sound signal) as shown in FIG. Then, the determination unit 12 determines that sound has been received (step S101), and compares the electrical signal shown in FIG. 6 with “sound information 001” corresponding to the collective entrance held in advance. In this case, it is assumed that both match. Then, the determination unit 12 determines that the calling sound of the collective entrance is emitted from the indoor terminal 3 (step S102), and passes that fact to the selection unit 15. Then, the selection unit 15 selects the collective entrance image information received by the collective entrance image information receiving unit 13 (step S105) and passes it to the output unit 16. The output unit 16 outputs the collective entrance image information to a display (monitor) (step S106). As a result, as shown in FIG. 5, the image of Mr. ABC who is a visitor is displayed on the monitor of A's house. In this way, the resident of A's house can check the image of Mr. ABC who is a visitor to the entrance hall on the monitor.

  Assume that the resident of A's house unlocks the door of the collective entrance after talking with ABC on the intercom system. Then, it is assumed that ABC opens the door of the collective entrance, enters the collective housing, comes to the individual entrance of the A home, and presses the call button of the individual entrance terminal 4 of the individual entrance. Then, a ringing tone “kinkon” corresponding to the individual entrance is emitted from the indoor terminal 3 of the home A.

  The microphone 11 receives the ring tone “kinkon” and converts it into an electrical signal (sound signal). Then, the determination unit 12 determines that sound has been received (step S101), and compares the electrical signal with “sound information 001” corresponding to the collective entrance held in advance. In this case, it is assumed that the two do not match. Then, the determination unit 12 determines that the calling sound of the collective entrance is not emitted from the indoor terminal 3 (step S102), and corresponds to the electrical signal from the microphone 11 and the individual entrance held in advance. The sound information 002 "is compared. In this case, it is assumed that both match. Then, the determination unit 12 determines that the ringing tone for the individual entrance is emitted from the indoor terminal 3 (step S103), and passes that effect to the selection unit 15. Then, the selection unit 15 selects the individual entrance image information received by the individual entrance image information reception unit 14 (step S104) and passes it to the output unit 16. The output unit 16 outputs the individual entrance image information to a display display (monitor) (step S106). As a result, as shown in FIG. 7, the image of Mr. ABC who is a visitor is displayed on the monitor of A's home. In this way, the resident of A's house can check the image of Mr. ABC who is a visitor to the individual entrance on the monitor.

  As described above, according to the entrance image output apparatus 1 according to the present embodiment, a monitor function can be added afterwards to an intercom system of an apartment house that does not have a monitor function. Therefore, the residents and tenants of the apartment house can check the visitors on the monitor, and the security level can be improved.

  Moreover, if the entrance image output apparatus 1 according to the present embodiment is used, the monitor function can be introduced without modifying the existing intercom system itself. Therefore, when the existing intercom system itself is changed to a system with a monitor function, the existing intercom system must be temporarily stopped, but the entrance image output apparatus 1 according to the present embodiment is used. In such a case, there is no need to stop the existing intercom system even when the monitor function is introduced, and the convenience of residents and tenants of the housing complex will not be harmed.

  Moreover, since the image displayed on the display device 21 is automatically selected if the entrance image output apparatus 1 according to the present embodiment is used, for example, the user manually sets the image displayed on the display device 21. Compared to the case, the convenience of the user is improved.

  Note that, when the collective entrance image information is not constantly transmitted to the entrance image output device 1 but only when request information is transmitted, the entrance image output device 1 is displayed as shown in FIG. The request information transmission unit 17 may be further provided. Here, the request information transmission unit 17 determines that the sound received by the microphone 11 is a ringing sound corresponding to the collective entrance from the intercom indoor terminal 3 in the intercom system of the apartment house. In addition, request information which is information for requesting transmission of the collective entrance image information is transmitted. The transmission destination of the request information may be, for example, the collective entrance camera 5 or a controller that controls the collective entrance camera 5. When the request information is received by the collective entrance camera 5 or the like, collective entrance image information indicating an image captured by the collective entrance camera 5 is transmitted to the entrance image output apparatus 1. In this way, the collective entrance image information receiving unit 13 receives the collective entrance image information transmitted in response to the transmission of the request information.

  Further, the display device 21 that displays image information does not always display image information. For example, when there is no input of image information for a certain period of time, the display device 21 enters a sleep state or shuts down. Or when not displaying image information unless it starts, the entrance image output device 1 may further be provided with the starting part 18 which starts the display device 21, as FIG. 9 shows. Here, in the activation unit 18, the determination unit 12 determines that the sound received by the microphone 11 is a ringing sound corresponding to the collective entrance or the individual entrance from the interphone indoor terminal 3 in the intercom system of the apartment house. In this case, the display device 21 is activated. As a starting method, for example, a starting command is transmitted to the display device 21 by a dedicated line or the like and the starting device is started by the starting command, or a television receiver or the like in which the display device 21 can be operated by a remote control (remote control). In some cases, there may be a method of transmitting an infrared signal for activating the display device 21 from the activation unit 18 and activating with the signal.

(Embodiment 2)
An entrance image output apparatus according to Embodiment 2 of the present invention will be described with reference to the drawings. The entrance image output apparatus according to the present embodiment outputs only collective entrance image information.

  The intercom system according to the present embodiment is the same as that of FIG. 1 of the first embodiment except that the individual entrance camera 2 does not need to be provided, and the description thereof is omitted.

  FIG. 10 is a block diagram showing a configuration of the entrance image output apparatus 20 according to the present embodiment. In FIG. 10, the entrance image output apparatus 20 according to the present embodiment includes a microphone 11, a collective entrance image information receiving unit 13, an output unit 16, and a determination unit 22. The configuration and operation other than the determination unit 22 are the same as those in the first embodiment, and a description thereof will be omitted.

  The determination unit 22 determines whether the sound received by the microphone 11 is a ringing sound emitted from the interphone indoor terminal 3 using an electric signal. Unlike the determination unit 12 of the first embodiment, the determination unit 22 of the present embodiment does not need to determine the type of the ringing tone, and only determines whether or not there is a ringing tone. Therefore, as described in the determination unit 12 of the first embodiment, the sound information indicating the ringing tone is held, and the presence or absence of the ringing tone is determined by pattern matching between the sound information and the electric signal from the microphone 11. Alternatively, the presence or absence of a ringing tone may be determined based on whether or not a sound having a predetermined level or higher is received by the microphone 11. In the latter case, in order to avoid misjudgment, it is preferable that no sound other than the ringing sound enters the microphone 11.

  Note that the output unit 16 is a collective entrance image information receiving unit when the judging unit 22 judges that the voice received by the microphone 11 is a ringing sound emitted from the interphone indoor terminal 3 in the intercom system of the apartment house. 13 outputs the image indicated by the collective entrance image information received to the display device 21.

  FIG. 11 is a flowchart showing the operation of the entrance image output apparatus 20 according to the present embodiment. Note that the processing in step S101 is the same as the flowchart in FIG. 3 of the first embodiment, and a description thereof will be omitted.

  (Step S201) The determination unit 22 determines whether the voice received by the microphone 11 is a ringing tone. And when it is a ringing tone, it progresses to step S202, and when that is not right, it returns to step S101.

(Step S <b> 202) The output unit 16 outputs the collective entrance image information received by the collective entrance image information receiving unit 13 to the display device 21. Then, the process returns to step S101. Note that the output of the image information to the display device 21 may end, for example, when a predetermined time (for example, 1 minute) elapses, and an instruction from the user (for example, the user presses the end button) Or the like, or may be terminated with another event as a trigger.
Note that the processing is ended by powering off or interruption for aborting the processing in the flowchart in FIG.

  The specific example of the operation of the entrance image output apparatus 20 and the operation of the intercom system according to the present embodiment is self-evident from the specific example of the first embodiment, and the description thereof is omitted.

  As described above, according to the entrance image output apparatus 20 according to the present embodiment, a monitor function can be added afterwards to an intercom system of an apartment house that does not have a monitor function. Therefore, the residents and tenants of the apartment house can check the visitors on the monitor, and the security level can be improved.

  If the collective entrance image information is not constantly transmitted to the entrance image output device 20 but only when the request information is transmitted, as shown in FIG. The request information transmitting unit 23 may be further provided as in the first embodiment. Here, when the determination unit 22 determines that the voice received by the microphone 11 is a ringing tone emitted from the intercom indoor terminal 3 in the intercom system of the apartment house, the request information transmission unit 23 collects the entrance image. Request information that is information for requesting transmission of information is transmitted. The transmission destination of the request information may be, for example, the collective entrance camera 5 or a controller that controls the collective entrance camera 5. When the request information is received by the collective entrance camera 5 or the like, collective entrance image information indicating an image captured by the collective entrance camera 5 is transmitted to the entrance image output device 20. In this way, the collective entrance image information receiving unit 13 receives the collective entrance image information transmitted in response to the transmission of the request information.

  Further, the display device 21 that displays image information does not always display image information. For example, when there is no input of image information for a certain period of time, the display device 21 enters a sleep state or shuts down.
