[0024] Figure 2 is a functional block diagram of the intercom system 1, consisting of the main entrance unit 10, server 20, room master unit 30, and control unit 60. As shown in Figure 2, the main entrance unit 10 includes a sub-unit display unit 11, a sub-unit microphone 12, and a sub-unit camera 13, as well as a main entrance unit CPU (Central Processing Unit) 14 and a communication interface (IF) 15.

[0025] The sub-unit display unit 11 is configured to display the call operation unit 111 and the information input unit 112. In other words, the sub-unit display unit 11 also functions as an input unit for receiving various operations from the user (for example, a visitor).

[0026] The call operation unit 111 is the unit that visitors operate when calling a resident. The call operation unit 111 consists of, for example, a keypad or call buttons displayed on the sub-unit display unit 11.

[0027] The information input unit 112 is configured to allow input of room information, etc. The room information may include the room number of the resident the visitor is visiting.

[0028] The sub-microphone 12 is used by visitors to the building to call and communicate with people inside the building. The sub-microphone 12 includes, for example, a microphone and speaker installed in the main entrance unit 10. The sub-microphone 12 is configured to open a communication line to a living room, allowing residents inside the living room and visitors in front of the main entrance unit 10 to communicate via the microphone and speaker of the main entrance unit 10.

[0029] The main entrance unit CPU 14 performs processing to control each part of the main entrance unit 10. The communication IF 15 forms a bidirectional signal transmission path between the main entrance unit CPU 14 and the intercom line L. As a result, a signal transmission path is formed between the main entrance unit CPU 14 and the control unit 60 via the communication IF 15.

[0030] The room master unit 30 includes a master unit display unit 31, an operation unit 32, and a master unit microphone 33, as well as a room camera 34, a master unit CPU 35, a communication IF 36, and a storage unit 37. The room camera 34 captures images of the resident when they respond to a call. The master unit CPU 35 performs processing to control each part of the room master unit 30. The communication IF 36 forms a bidirectional signal transmission path between the master unit CPU 35 and the intercom line L. This forms a signal transmission path between the master unit CPU 35 and the control unit 60. The storage unit 37 stores control information and other data for the room master unit 30. The storage unit 37 also stores image data captured by the sub-unit camera 13 of the main entrance unit 10 and the entrance camera 43 of the entrance sub-unit 40, and transmitted from the main entrance unit 10 and the entrance sub-unit 40.

[0031] The control unit 60 comprises a control unit 61 and a storage unit 62. The control unit 61 can communicate with the main entrance unit 10, server 20, room master unit 30, etc., which are connected to the control unit 60, and controls the transmission of signals between each unit and the connection to the network N. The storage unit 62 stores communication information, control information, etc. In this example, the storage unit 62 stores a recorded call table 62a in which visitor ID information is registered in advance.

[0032] The control unit 61 is configured to control the sub-microphone 12 via the main entrance unit CPU 14. The control unit 61 receives a signal containing room number information entered at the call operation unit 111 of the main entrance unit 10. The control unit 61 then refers to the call table 62a in the storage unit 62 to identify the room master unit 30 of the dwelling unit that corresponds to the room number entered at the call operation unit 111. The control unit 61 then transmits a call signal to the identified room master unit 30.

[0033] Figure 3 is a functional block diagram of the control unit 61 in this embodiment. As illustrated in Figure 3, the control unit 61 includes a sign language recognition unit 611, a sign language text conversion unit 612, a speech recognition unit 613, and a speech text conversion unit 614.

[0034] The sign language recognition unit 611 receives video footage captured by the sub-camera 13 and the room camera 34 and is configured to recognize that sign language is included in the hand movements of visitors or residents. The sign language recognition unit 611 is configured to output the recognized sign language information as sign language information.

[0035] The sign language text conversion unit 612 converts the sign language information output by the sign language recognition unit 611 into text information and outputs it. The control unit 61 is configured to transmit the text information output by the sign language text conversion unit 612 to the main entrance unit 10 or the room master unit 30.

[0036] The voice recognition unit 613 is configured to recognize voice received by the sub-unit microphone 12 and the master unit microphone 33. The voice recognition unit 613 is configured to output the information from the recognized voice as voice information.

[0037] The speech-to-text conversion unit 614 converts the speech information output by the speech recognition unit 613 into text information and outputs it. The control unit 61 is configured to transmit the text information output by the speech-to-text conversion unit 614 to the main entrance unit 10 or the room master unit 30.

[0038] Returning to Figure 2, the control unit 61 is configured to receive information from the external server 70 regarding sign language recognition, speech recognition, conversion from sign language to text, and conversion from speech to text. The received information is stored in the storage unit 62 and transmitted to the server 20. Alternatively, the control unit 61 may transfer the information received from the external server 70 to the server 20 without storing it in the storage unit 62.

[0039] The server 20 comprises a generation unit 21 and a storage unit 22. The generation unit 21 can generate a predetermined data table 22a based on ID information received from the external server 70 via the controller 60. The storage unit 22 stores the data table 22a generated by the generation unit 21.

[0040] Next, the operation of the intercom system 1 according to this embodiment will be described. First, we will describe the case when a visitor with a hearing impairment visits a room.

[0041] The visitor operates the information input unit 112 displayed on the sub-unit display unit 11 of the main entrance unit 10 to make a call to the resident's room. The sub-unit camera 13 captures images of the visitor at least while the resident is responding to the call. The captured images are transmitted to the control unit 61.

[0042] Figure 4 illustrates an image G1 captured by the sub-camera 13 or the room camera 34. As illustrated in Figure 4, the image G1 is captured in such a way that the visitor's face and hands are visible.

[0043] Here, when the sign language recognition unit 611 determines that sign language can be recognized from the hand movements of the visitor captured by the sub-camera 13 or the room camera 34, it recognizes the meaning of the sign language and outputs it as sign language information. At this time, the control unit 61 may change the imaging range of the sub-camera 13 or the room camera 34 to change the captured image G1 captured by the sub-camera 13 or the room camera 34 into a sign language image G2. The sign language image G2 is captured with an imaging range that shows the visitor's hand in a magnified view.

[0044] Figure 5 illustrates the conversion of sign language information from a visitor into text information in the control unit 61. As illustrated in Figures 3 and 5, in the control unit 61, when the sign language recognition unit 611 recognizes the visitor's sign language and outputs sign language information, the sign language text conversion unit 612 converts the sign language information into text information. The control unit 61 transmits the text information to the room master unit 30 and displays it on the master unit display unit 31.

[0045] For example, if, during a call, the sub-unit camera 13 captures a visitor saying "Hello. This is Takahashi." in sign language, the sign language recognition unit 611 recognizes that the sign language in the captured sign language image G2 means "Hello. This is Takahashi." The sign language recognition unit 611 outputs sign language information to that effect, and the sign language text conversion unit 612 converts the sign language information into text information containing the words "Hello. This is Takahashi." and outputs it. The control unit 61 transmits the text information to the room master unit 30, causing the master unit display unit 31 to display the string "Hello. This is Takahashi." as illustrated in Figure 5.

[0046] Figure 6 illustrates the conversion of voice information from a resident's voice into text information in the control unit 61. As illustrated in Figures 3 and 6, in the control unit 61, when the voice recognition unit 613 recognizes a resident's voice and outputs voice information, the voice-to-text conversion unit 614 converts the voice information into text information. The control unit 61 transmits the text information to the main entrance unit 10 and displays it on the sub-unit display unit 11.

[0047] For example, if the master unit microphone 33 receives a voice message from a resident saying, "Welcome. I'll open the door now," during a call operation, the voice recognition unit 613 recognizes that the resident is saying, "Welcome. I'll open the door now." The voice recognition unit 613 outputs the voice information to that effect, and the voice-to-text conversion unit 614 converts the voice information into text information including the words "Welcome. I'll open the door now," and outputs it. When the room master unit 30 receives the text information, the master unit display unit 31 displays the string "Welcome. I'll open the door now."

[0048] The conversion from sign language information to text information, and from voice information to text information, may be started automatically when the sign language recognition unit 611 determines that the visitor's hand movements can be recognized as sign language. Alternatively, the conversion from sign language information to text information, and from voice information to text information may be started by operation of the main entrance unit 10. Figure 7 illustrates the initial screen 200 displayed on the sub-unit display unit 11 of the main entrance unit 10. The initial screen 200 displays the mode input unit 201. When the visitor operates the mode input unit 201 to select the sign language conversion mode, the conversion from sign language information to text information, and from voice information to text information are started.

[0049] According to the intercom system 1 of this embodiment, sign language can be recognized from the visitor's hand movements, and the read sign language information can be displayed as text on the master unit display unit 31. This allows the visitor's intentions to be smoothly communicated to the resident, even if the visitor is hearing impaired.

[0050] According to the intercom system 1 of this embodiment, when sign language is recognized from the visitor's hand movements, the imaging range of the sub-unit camera 13 is changed to enlarge the visitor's hands, making it easier for the sign language recognition unit 611 of the control unit 61 to recognize sign language information more accurately from the visitor's hand movements.

[0051] According to the intercom system 1 of this embodiment, the resident's voice information is displayed as text information on the sub-unit display unit 11, so that even if the visitor is hearing impaired, the resident's intentions can be smoothly conveyed to the visitor.

[0052] According to the intercom system 1 of this embodiment, visitors can communicate their intentions in sign language and receive the intentions of the resident in writing by selecting a sign language conversion mode through the operation of the mode input unit 201. As a result, even if the visitor is hearing impaired, the visitor and the resident can communicate smoothly with each other.

[0053] Next, we will explain the case where a visitor visits the room where a resident with a hearing impairment resides.

[0054] Figure 8 illustrates the conversion of sign language information from a resident into text information by the control unit 61. As illustrated in Figures 3 and 8, when the control unit 61 recognizes the sign language from a resident using the sign language recognition unit 611 and outputs the sign language information, the sign language text conversion unit 612 converts the sign language information into text information. The control unit 61 transmits the text information to the main entrance unit 10 and displays it on the sub-unit display unit 11.

[0055] For example, if the room camera 34 captures a resident saying "Yes, who is it?" in sign language during a call operation, the sign language recognition unit 611 recognizes in the captured sign language image G2 that the sign language means "Yes, who is it?". The sign language recognition unit 611 outputs sign language information to that effect, and the sign language text conversion unit 612 converts the sign language information into text information including the words "Yes, who is it?" and outputs it. The control unit 61 transmits the text information to the main entrance unit 10, causing the string "Yes, who is it?" to be displayed on the sub-unit display unit 11, as illustrated in Figure 8.

[0056] Figure 9 illustrates the conversion of audio information from a visitor's voice into text information in the control unit 61. As illustrated in Figures 3 and 9, in the control unit 61, when the voice recognition unit 613 recognizes the visitor's voice and outputs audio information, the voice-to-text conversion unit 614 converts the audio information into text information. The control unit 61 transmits the text information to the room master unit 30 and displays it on the master unit display unit 31.

[0057] For example, if, during a call, the sub-unit microphone 12 receives a voice message from a visitor saying, "Hello. This is XX Express. We've come to deliver your package," the voice recognition unit 613 recognizes that the visitor is saying, "Hello. This is XX Express. We've come to deliver your package." The voice recognition unit 613 outputs the voice information to that effect, and the voice-to-text conversion unit 614 converts the voice information into text information including the words "Hello. This is XX Express. We've come to deliver your package," and outputs it to the room master unit 30. When the room master unit 30 receives the text information, the master unit display unit 31 displays the string "Hello. This is XX Express. We've come to deliver your package."

[0058] According to the intercom system 1 of this embodiment, sign language can be recognized from the resident's hand movements, and the read sign language information can be displayed as text on the sub-unit display unit 11. This allows for smooth communication between visitors and residents, even if the resident is hearing impaired.

[0059] According to the intercom system 1 of this embodiment, when sign language is recognized from the resident's hand movements, the imaging range of the room camera 34 is changed to enlarge the resident's hands, making it easier for the control unit 61 to recognize sign language information more accurately from the resident's hand movements.

[0060] According to the intercom system 1 of this embodiment, the visitor's voice information is displayed as text information on the master unit display unit 31, so that even if the resident is hearing impaired, the visitor's intentions can be smoothly conveyed to the resident.

[0061] Furthermore, this disclosure is not limited to the embodiments described above, and can be freely modified, improved, etc. as appropriate. In addition, the material, shape, dimensions, numerical values, form, number, placement location, etc. of each component in the embodiments described above are arbitrary and not limited as long as they can achieve this disclosure.

[0062] If both the resident and the visitor are hearing impaired, the image captured by the room camera 34 may be displayed on the sub-unit display unit 11 of the main entrance unit 10, and the image captured by the sub-unit camera 13 may be displayed on the master unit display unit 31 of the room master unit 30. Furthermore, if the sign language recognition unit 611 recognizes sign language from the images captured by the sub-unit camera 13 and the room camera 34, the outputted sign language information may be displayed on the master unit display unit 31 and the sub-unit display unit 11 as a character-based representation of sign language.
