[0011] In each of the embodiments described below, the information terminal, intercom system, and program of the Disclosure will be explained with reference to the drawings. However, each of the embodiments described below is only a part of the various embodiments of the Disclosure. Each of the embodiments described below can be modified in various ways depending on the design, etc., as long as the objectives of the Disclosure are achieved. In addition, the figures described in each of the embodiments described below are schematic diagrams, and the ratios of the size and thickness of each component in the figures do not necessarily reflect the actual dimensional ratios.

[0012] (Embodiment 1) (overview) The information terminal 1 and intercom system 100 of this embodiment, as shown in Figure 1, are installed and used in a complex facility that includes multiple facilities. A complex facility is, for example, an apartment building, an office building that includes multiple sections that can be occupied by multiple businesses, or a factory that includes multiple sections. A facility is, for example, a dwelling unit. In this disclosure, "dwelling unit" means a space that can be exclusively occupied by one or more natural persons or legal entities. The concept of "dwelling unit" is not limited to spaces used for residential purposes, but also includes spaces used for purposes other than residential purposes. If the complex facility is an apartment building, each individual unit in the apartment building is a dwelling unit (facility). If the complex facility is an office building, each of the multiple sections that are leased or sold within the office building is a dwelling unit (facility). If the complex facility is a factory that includes multiple sections and access to each section is managed, each of the multiple sections is a dwelling unit (facility).

[0013] The information terminal 1 is installed in an apartment building (facility) including a plurality of households (facilities). The information terminal 1 includes a call unit 44, a first input unit 41, a second input unit 42, and an image output unit 43. The call unit 44 has a function of establishing communication for calls with a plurality of household terminals 3 installed in a plurality of households. The first input unit 41 receives the input of first data from a first imaging system 61 installed in the apartment building. The first data includes a first image captured by the first imaging system 61. The second input unit 42 receives the input of second data from a second imaging system 62 installed in the apartment building. The second data includes a second image captured by the second imaging system 62. The image output unit 43 outputs image data based on at least one of the first data and the second data.

[0014] In the information terminal 1 of the present embodiment, the image output unit 43 can output not only image data based on the first data, but also image data based on the second data, or image data based on both the first data and the second data. That is, compared with the case where the image output unit 43 outputs only image data based on the first data, various image data can be output. As a result, the convenience is improved for the user who refers to the image data. <000008​​​​​​​​​​​​​​In this embodiment, the first imaging system 61 is positioned to capture images of the caretaker H1 of the community facility and generates a first image of the caretaker H1. Meanwhile, the second imaging system 62 is positioned to capture images of a visitor H2 to the community facility and generates a second image of the visitor H2.

[0019] Visitor H2 to the community facility converses face-to-face with manager H1, who is at the reception area in the entrance of the community facility. At this time, a first image of manager H1 and a second image of visitor H2 are input to information terminal 1. Image data based on at least one of the first data including the first image and the second data including the second image is output to dwelling terminal 3. At least one of the first image and the second image is displayed on the display unit 38 of dwelling terminal 3. This allows resident H3 of the dwelling unit to confirm the appearance of visitor H2 and to check the details of the conversation between visitor H2 and manager H1. Based on the results, resident H3 can decide, for example, whether or not to talk to visitor H2, or whether or not to invite visitor H2 into their home (dwelling unit).

[0020] Furthermore, after the conversation between manager H1 and visitor H2 is completed or interrupted, communication for a call may be established between information terminal 1 and dwelling terminal 3 as needed, allowing manager H1 and resident H3 to communicate. This allows, for example, manager H1 to convey information heard from visitor H2 (such as the purpose of the visit) to resident H3. Alternatively, for example, resident H3 may inform manager H1 that they will invite visitor H2 into their home (dwelling), and in response, manager H1 will unlock the entrance door D1 of the building, allowing visitor H2 to proceed to the dwelling where resident H3 is located.

[0021] Furthermore, after the conversation between the building manager H1 and the visitor H2 is completed or interrupted, if necessary, communication for a conversation may be established between the information terminal 1 and the dwelling unit terminal 3, and the visitor H2 and resident H3 may have a conversation.

[0022] (detail) (1) Overall structure As shown in Figure 1, the intercom system 100 includes an information terminal 1 and a plurality of dwelling unit terminals 3. The plurality of dwelling unit terminals 3 receive input of image data output from the image output unit 43. The intercom system 100 further includes a lobby intercom 2, a first imaging system 61, a second imaging system 62, a first microphone 81, a second microphone 82, a plurality of branch switches 7, a main line L1, and a plurality of branch lines L2.

[0023] Information terminal 1 is installed at the entrance of the collective facility. Information terminal 1 comprises a communication interface 11, an operation unit 12, a processing unit 4, a microphone 16, a speaker 17, and a display unit 18.

[0024] The lobby intercom 2 is installed at the entrance of the apartment complex. The lobby intercom 2 is used when a visitor H2 communicates with a resident H3 without going through the building manager H1. The lobby intercom 2 comprises a communication interface 21, an operating unit 22, a processing unit 23, a microphone 26, a speaker 27, and a display unit 28.

[0025] Multiple dwelling unit terminals 3 correspond one-to-one with multiple dwelling units. Each dwelling unit terminal 3 is installed inside the corresponding dwelling unit. Each of the multiple dwelling unit terminals 3 is equipped with a communication interface 31, an operation unit 32, a processing unit 33, a microphone 36, a speaker 37, and a display unit 38. Each dwelling unit terminal 3 is a residential information panel that functions as an intercom master unit as well as having alarm functions and the like. Alarm functions include, for example, a fire alarm function, a gas leak alarm function, a water leak alarm function, and a function to alert the open status of windows and doors.

[0026] (2) Communication IF Information terminal 1 and lobby intercom 2 can communicate with each other via communication IFs 11 and 21. In this disclosure, "communication possible" means that signals can be sent and received directly or indirectly via a network or repeater, etc., by an appropriate communication method such as wired communication or wireless communication. In this embodiment, information terminal 1 and lobby intercom 2 send and receive signals via a wired communication path.

[0027] Information terminal 1 and dwelling terminal 3 can communicate with each other via communication IFs 11 and 31. In this embodiment, information terminal 1 and dwelling terminal 3 exchange signals via a wired communication path.

[0028] Each of the main trunk line L1 and the multiple branch lines L2 consists of, for example, twisted pair cable. In Figure 1, each of the main trunk line L1 and the multiple branch lines L2 is shown as a single line.

[0029] A main line L1 extends from information terminal 1. The main line L1 branches into multiple branch lines L2. Each of the multiple branch lines L2 extends to the corresponding dwelling unit terminal 3. In other words, information terminal 1 and the multiple dwelling unit terminals 3 are electrically connected via the main line L1 and the multiple branch lines L2. A turnout switch 7 is provided at the branching point between the main line L1 and each branch line L2.

[0030] Preferably, on the main line L1, an amplifier for amplifying signals is installed between multiple turnouts 7 and information terminals 1.

[0031] The lobby intercom 2 and the dwelling unit terminal 3 can communicate with each other via the information terminal 1. In other words, the information terminal 1 relays communication between the lobby intercom 2 and the dwelling unit terminal 3.

[0032] (3)Operation section Information terminal 1, lobby intercom 2, and dwelling terminal 3 are each equipped with operation units 12, 22, and 32. Operation units 12, 22, and 32 receive user input. When an operation is performed on operation units 12, 22, and 32, processing units 4, 23, and 33 respond accordingly. Therefore, for example, communication between information terminal 1, lobby intercom 2, and dwelling terminal 3 can be established or terminated in response to an operation on operation units 12, 22, and 32. Furthermore, various settings of the intercom system 100 can be adjusted by operating operation units 12, 22, and 32.

[0033] The operation units 12, 22, and 32 include, for example, one or more buttons, a touch panel (or touch panel display), or a combination thereof. The one or more buttons include, for example, a numeric keypad with numbers 0-9, an asterisk (*) button, a cancel button, and a call button. When the caretaker H1 wants to call resident H3 of an apartment with a certain apartment number, he presses the numeric keypad on the operation unit 12 of the information terminal 1 to enter the apartment number. Finally, when the caretaker H1 presses the call button, the input of the apartment number is confirmed, and a call is made from the information terminal 1 to the apartment terminal 3 of that apartment.

[0034] (4) Processing apparatus Information terminal 1, lobby intercom 2, and dwelling terminal 3 are each equipped with processing units 4, 23, and 33, respectively. Processing units 4, 23, and 33 each include a computer system having one or more processors and memory. At least some of the functions of each of the information terminal 1, lobby intercom 2, and dwelling terminal 3 are realized by the execution of a program recorded in the memory of the computer system by the processor of the computer system. The program may be recorded in memory, provided via a telecommunications line such as the Internet, or provided on a non-temporary recording medium such as a memory card.

[0035] The processing unit 4 performs overall control of the information terminal 1. Details of the processing unit 4 will be described later.

[0036] Processing unit 23 controls the lobby intercom 2 overall. Processing unit 33 controls the dwelling unit terminal 3 overall.

[0037] (5) Microphone Information terminal 1, lobby intercom 2, and dwelling unit terminal 3 are equipped with microphones 16, 26, and 36, respectively. In addition, a first microphone 81 and a second microphone 82 are installed in the reception area at the entrance. Microphones 16, 26, 36, the first microphone 81, and the second microphone 82 convert ambient sound into electrical signals. The first microphone 81 is positioned to pick up the voice of the building manager H1. The second microphone 82 is positioned to pick up the voice of the visitor H2.

[0038] (6) Speaker Information terminal 1, lobby intercom 2, and dwelling unit terminal 3 are each equipped with speakers 17, 27, and 37. Speakers 17, 27, and 37 convert sound data into sound (air vibrations) and output it.

[0039] (7)Display section The information terminal 1, the lobby intercom 2, and the dwelling unit terminal 3 are each equipped with display units 18, 28, and 38. The display units 18, 28, and 38 are displays that show images. The display units 18, 28, and 38 display, for example, images captured by the first imaging system 61 or the second imaging system 62. In addition, the display units 18, 28, and 38 display, for example, various setting information of the intercom system 100.

[0040] (8) Imaging system The first imaging system 61 and the second imaging system 62 each include a camera (visible light camera). The camera has a two-dimensional image sensor, such as a CCD (Charge Coupled Devices) image sensor or a CMOS (Complementary Metal-Oxide Semiconductor) image sensor. The first imaging system 61 outputs the image captured by the camera as the first image. The second imaging system 62 outputs the image captured by the camera as the second image. In addition, at least one of the first imaging system 61 and the second imaging system 62 may have an image processing unit that performs image processing on the image captured by the camera. Examples of image processing include image compression, scaling, cropping, distortion correction, and noise reduction. The image processing unit is implemented, for example, by a DSP (Digital Signal Processor) or an FPGA (Field-Programmable Gate Array).

[0041] The first imaging system 61 is installed in the same space as the second imaging system 62. The target of imaging by the first imaging system 61 is different from the target of imaging by the second imaging system 62. Specifically, the first imaging system 61 targets caretaker H1, while the second imaging system 62 targets visitor H2.

[0042] As shown in Figure 2, the first imaging system 61 is provided independently of the information terminal 1. However, the first imaging system 61 may be incorporated into the information terminal 1. Also, at least some of the functions of the first imaging system 61 (for example, functions related to image processing) may be implemented by the information terminal 1.

[0043] The second imaging system 62 is provided independently of the information terminal 1. However, the second imaging system 62 may be incorporated into the information terminal 1. Furthermore, at least some of the functions of the second imaging system 62 (for example, image processing functions) may be implemented by the information terminal 1.

[0044] (9) Processing device of information terminal As shown in Figure 1, the processing unit 4 of the information terminal 1 includes a first input unit 41, a second input unit 42, an image output unit 43, a call unit 44, a setting unit 45, a first sound input unit 46, a second sound input unit 47, a sound output unit 48, an authentication unit 49, and a lock control unit 50. Note that these merely represent the functions realized by the processing unit 4 and do not necessarily represent an actual physical configuration.

[0045] (9.1) Main functions The first input unit 41 receives input of the first data output from the first imaging system 61. That is, the first data output from the first imaging system 61 is received by the communication IF 11 and provided to the processing unit 4 (first input unit 41) via the communication IF 11. The first data may include only the first image captured by the first imaging system 61.

[0046] The second input unit 42 receives input of the second data output from the second imaging system 62. That is, the second data output from the second imaging system 62 is received by the communication IF 11 and provided to the processing unit 4 (second input unit 42) via the communication IF 11. The second data may consist only of the second image captured by the second imaging system 62.

[0047] The communication IF 11 of the information terminal 1 includes a first terminal for communicating with the first imaging system 61 and a second terminal for communicating with the second imaging system 62. The first input unit 41 receives input of first data via the first terminal. The second input unit 42 receives input of second data via the second terminal.

[0048] The image output unit 43 outputs image data. The image output unit 43 may output data obtained by processing at least one of the first data and the second data as image data. Examples of processing include conversion of data format and data compression. Alternatively, the image output unit 43 may output at least one of the first data and the second data as image data as is. In the following explanation, we will assume that the image output unit 43 outputs at least one of the first data and the second data as image data as is.

[0049] The communication unit 44 has the function of establishing communication for a call between the information terminal 1 and the multiple dwelling terminals 3. Specifically, communication for a call is established when a call start signal, which indicates an instruction to start a call, is exchanged between the information terminal 1 and the multiple dwelling terminals 3.

[0050] (9.2) Image Output The setting unit 45 configures settings related to the image data output from the image output unit 43. One example of setting related to image data is setting whether the image output unit 43 outputs image data based on the first data or the second data. In other words, the setting unit 45 sets whether the image output unit 43 outputs image data based on the first data or the second data.

[0051] The image output unit 43 provides (outputs) image data to the dwelling unit terminal 3. The image output unit 43 outputs image data to at least one of the multiple dwelling unit terminals 3. In this embodiment, the image output unit 43 outputs image data only to the dwelling unit terminal 3 of one dwelling unit designated by the building manager H1.

[0052] When the image output unit 43 outputs image data to the dwelling terminal 3, it initially outputs image data based on whichever of the first data and second data is set for each dwelling terminal 3. More specifically, resident H3 sets whether the image output unit 43 will initially output image data based on the first data or the second data by operating the operation unit 32 of the dwelling terminal 3. The setting information is output from the dwelling terminal 3 to the information terminal 1 and stored in the memory of the information terminal 1. The image data output from the image output unit 43 to the dwelling terminal 3 is displayed on the display unit 38. In other words, resident H3 can perform an "initial image setting" by operating the operation unit 32 of the dwelling terminal 3 to select the image to be displayed first. The initial image setting is a function of the setting unit 45 of the information terminal 1. In other words, the setting unit 45 sets the image data in response to the user's (resident H3's) operation on the setting device (dwelling terminal 3).

[0053] More specifically, among multiple dwelling units, the information terminal 1 sends a call signal to the dwelling unit terminal 3 of the dwelling unit designated by the building manager H1. For example, building manager H1 asks visitor H2 for the dwelling unit number of the dwelling unit H2 is in for business, and then enters the dwelling unit number into the operation unit 22 of the lobby intercom 2 to specify the dwelling unit. The call signal includes the identification information of the dwelling unit terminal 3. When the dwelling unit terminal 3 determines that the identification information contained in the call signal matches its own identification information, it authenticates that the call signal is addressed to it. The setting unit 45 of the information terminal 1 reads setting information (initial image setting information) corresponding to the identification information contained in the call signal from memory, and sets (determines) whether the image output unit 43 will output image data based on the first data or the second data. In other words, the setting unit 45 sets whether the image output unit 43 will output image data based on the first data or the second data, based on a call signal output by the information terminal 1 to call the operator (resident H3) of at least one dwelling terminal 3. The image output unit 43 also outputs image data to at least one dwelling terminal 3 when the information terminal 1 outputs a call signal to call the operator (resident H3) of at least one dwelling terminal 3.

[0054] Furthermore, after the image data based on whichever of the first or second data set is displayed on the display unit 38, the displayed image can be switched by the resident H3's operation on the operation unit 32 of the dwelling terminal 3. For example, each time a specific operation is performed on the operation unit 32, the image output unit 43 switches between outputting image data based on the first data and outputting image data based on the second data. In other words, when image data is displayed on the display unit 38 of the dwelling terminal 3, the setting unit 45 switches the image data output by the image output unit 43 in response to the user's (resident H3's) operation on the setting device (dwelling terminal 3).

[0055] The setting device for users to configure image data settings is not limited to the dwelling unit terminal 3. The setting device may be, for example, a mobile device such as a smartphone or tablet owned by resident H3 or building manager H1. Alternatively, information terminal 1 may function as a setting device.

[0056] Furthermore, when second data is input from the second imaging system 62 to the second input unit 42, the display unit 18 of the information terminal 1 displays image data based on the second data. In other words, the information terminal 1 is equipped with a display unit 18 that displays image data.

[0057] Furthermore, information terminal 1 and dwelling terminal 3 each correspond to display devices having the function of displaying image data. The image output unit 43 outputs image data to the display device. The image data output from the image output unit 43 includes real-time image data that is displayed in real time on the display device, and timely image data that is displayed at a desired timing on the display device. For example, when image data is output to dwelling terminal 3, dwelling terminal 3 displays the real-time image data on the display unit 38 in real time and stores the timely image data in the memory of dwelling terminal 3. When resident H3 operates the operation unit 32 of dwelling terminal 3 and, for example, specifies the date and time of shooting, the display unit 38 of dwelling terminal 3 displays the timely image data corresponding to the specified date and time of shooting.

[0058] If there is sufficient available communication bandwidth for communication between the information terminal 1 and the dwelling terminal 3, the image output unit 43 may output both immediate image data and timely image data. On the other hand, if there is insufficient available communication bandwidth, the image output unit 43 may output only immediate image data. Also, for example, if the resident H3 of the dwelling is absent, the image output unit 43 may output only timely image data. Furthermore, for example, the image output unit 43 may be configured to output immediate image data, timely image data, or both, through a setting operation on the operation unit 32 of the dwelling terminal 3.

[0059] (9.3) Sound Output The first sound input unit 46 receives input of first sound data, which is obtained by converting the sounds around the imaging target (manager H1) of the first imaging system 61 into electrical signals. In other words, the first sound input unit 46 receives input of first sound data generated by the first microphone 81.

[0060] The second sound input unit 47 receives input of second sound data, which is obtained by converting the sounds around the target being imaged by the second imaging system 62 (visitor H2) into electrical signals. In other words, the second sound input unit 47 receives input of second sound data generated by the second microphone 82.

[0061] The sound output unit 48 outputs at least one of the first sound data and the second sound data. More specifically, the sound output unit 48 outputs at least one of the first sound data and the second sound data to the dwelling terminal 3. When the sound output unit 48 outputs the first sound data, the image output unit 43 outputs image data based on the first data. On the other hand, when the sound output unit 48 outputs the second sound data, the image output unit 43 outputs image data based on the second data. The dwelling terminal 3 outputs the received first sound data or second sound data as sound from the speaker 37. The dwelling terminal 3 also displays the image data on the display unit 38. In other words, when the image of manager H1 is displayed on the display unit 38 of the dwelling terminal 3, the voice of manager H1 is output from the speaker 37, and when the image of visitor H2 is displayed on the display unit 38, the voice of visitor H2 is output from the speaker 37.

[0062] Furthermore, the sound data output from the sound output unit 48 (including at least one of the first sound data and the second sound data) includes real-time sound data that is played back in real time on the display device (dwelling terminal 3) and timely sound data that is played back at a desired timing on the display device. When real-time image data is displayed on the display device, the real-time sound data is also played back simultaneously. When timely image data is displayed on the display device, the timely sound data is also played back simultaneously.

[0063] Preferably, the output of the first sound data and the second sound data in the sound output unit 48 can be switched by operating the operation unit 32 of the dwelling terminal 3. In other words, by operating the operation unit 32, resident H3 can enable the output of one or both of the first sound data and the second sound data, or enable the output of neither the first sound data nor the second sound data. Alternatively, the output of the first sound data and the second sound data in the sound output unit 48 can be switched by operating the operation unit 12 of the information terminal 1. Furthermore, the first sound data may not be output by muting the first microphone 81, and the second sound data may not be output by muting the second microphone 82.

[0064] (9.4) Authentication Preferably, the second data includes the second image, as well as data related to the second image. The data related to the second image includes, for example, data related to the authentication of the person (visitor H2) in the second image. Then, the device (dwelling terminal 3) that receives the image data based on the second data displays the data related to the second image.

[0065] More specifically, the authentication unit 49 analyzes the second image to authenticate the person in the second image. Authentication may be, for example, facial recognition or iris recognition. The authentication unit 49 compares the feature quantities of the person in the second image with the feature quantities of one or more people pre-stored in the memory of the information terminal 1. The memory of the information terminal 1 stores, for example, the feature quantities of multiple residents of multiple dwelling units. If the authentication unit 49 determines, as a result of the comparison, that the person in the second image and a specific person pre-stored in the memory of the information terminal 1 are the same person, it outputs the determination result along with the label stored in the memory. The label may be, for example, information indicating whether or not entry is permitted, or it may be information about the specific person, such as the name and attributes of the specific person. The image output unit 43 outputs the second data, including the determination result and label, to the dwelling unit terminal 3. The display unit 38 of the dwelling unit terminal 3 displays the determination result and label. As a result, resident H3 can obtain information such as the attributes of visitor H2.

[0066] Furthermore, for example, the memory of information terminal 1 stores characteristic data of a person who frequently visits the collective facility (in this case, a delivery person). If the authentication unit 49 determines, based on the comparison, that the person in the second image and the person pre-stored in the memory of information terminal 1 are the same person, it outputs the determination result along with the label stored in the memory. The label may be, for example, information indicating whether or not entry is permitted, or information indicating that the person is a delivery person.

[0067] Furthermore, for example, the memory of information terminal 1 stores characteristic data of people whose entry to the public facility is restricted due to disruptive behavior, etc. If the authentication unit 49 determines, as a result of the comparison, that the person in the second image and the person previously stored in the memory of information terminal 1 are the same person, it outputs the determination result along with the label stored in the memory. The label may be, for example, information indicating whether or not entry is permitted, information indicating that the person is a person whose entry is restricted, or information indicating the reason why the person's entry is restricted.

[0068] Administrator H1 can decide whether or not to store the second image, which was captured by the second imaging system 62 and shows visitor H2, in memory along with its label by operating the information terminal 1.

[0069] (9.5) Lock control unit The lock control unit 50 of the information terminal 1 locks and unlocks the electric lock installed on the entrance door D1 (see Figure 2) of the common entrance in response to operations on the operation unit 12.

[0070] (10) Operation Flow The operation flow of the intercom system 100 will be explained below with reference to Figure 4. Note that the sequence diagram shown in Figure 4 is merely one example of the operation flow of the intercom system 100; the order of processing may be changed as appropriate, and processing may be added or omitted as appropriate.

[0071] Visitor H2 visits the apartment complex and speaks with manager H1. Visitor H2 tells manager H1 the apartment number of the apartment they wish to visit. Manager H1 operates the control panel 12 of information terminal 1 to specify the apartment number given by visitor H2 (step S21). The lobby intercom 2 then outputs a call signal to the apartment terminal 3 associated with the specified apartment number (step S22).

[0072] Furthermore, when the administrator H1 specifies the apartment number, the information terminal 1 causes the first imaging system 61 and the second imaging system 62 to start imaging (step S23). At the same time, the microphone 16 of the information terminal 1 starts sound acquisition processing, which captures sound and converts it into an electrical signal (step S23).

[0073] When a call signal is output to the dwelling terminal 3 in step S22, the dwelling terminal 3 notifies resident H3 that visitor H2 has arrived, for example by emitting a sound from speaker 37. Resident H3 responds to the call by, for example, operating the operation unit 32 of the dwelling terminal 3 (step S24). The dwelling terminal 3 then outputs a request signal to information terminal 1 to request image data and sound data (step S25).

[0074] Information terminal 1 acquires first data and second data from the first imaging system 61 and the second imaging system 62, and generates image data based on at least one of the first data and the second data. When information terminal 1 receives a request signal from dwelling terminal 3, it outputs the image data to dwelling terminal 3 (step S26). Information terminal 1 also acquires first sound data and second sound data from its microphone 16. When information terminal 1 receives a request signal from dwelling terminal 3, it outputs at least one of the first sound data and the second sound data (sound data) to dwelling terminal 3 (step S26).

[0075] The dwelling terminal 3 displays image data on the display unit 38 and plays sound data on the speaker 37 according to the settings made by the setting unit 45 (step S27). For example, according to the settings, the display unit 38 initially displays the second image of visitor H2, and each time a specific operation is performed on the operation unit 32, it alternately displays the first image and the second image. Also, for example, when visitor H2 is speaking, the dwelling terminal 3 receives the second sound data, and when manager H1 is speaking, the dwelling terminal 3 receives the first sound data, so the speaker 37 plays the sound data that was most recently input.

[0076] Next, the building manager H1 establishes communication for a call between the information terminal 1 and the dwelling unit terminal 3 by performing a predetermined operation on the information terminal 1. This enables a call between the building manager H1 and resident H3 (step S28). Specifically, the information terminal 1 plays the voice (or image and voice) of resident H3, and the dwelling unit terminal 3 plays the image and voice of the building manager H1. The building manager H1 asks resident H3 whether it is permissible to unlock the entrance door D1 of the building (step S29). If resident H3 permits unlocking, the building manager H1 operates the operation unit 12 of the information terminal 1, which causes the lock control unit 50 to drive the electric lock installed on the entrance door D1, unlocking the entrance door D1. This allows the visitor H2 to pass through the entrance door D1 and proceed to the dwelling unit where resident H3 is located.

[0077] Furthermore, the call can be terminated by operating the control unit 32 of the dwelling terminal 3 or the control unit 12 of the information terminal 1. In other words, the communication for the call between the information terminal 1 and the dwelling terminal 3 can be disconnected by operating the control unit 32 or the control unit 12. Alternatively, the communication for the call may be disconnected when the entrance door D1 is unlocked.

[0078] (Modification 1 of Embodiment 1) The following describes an intercom system 100 according to a modified example 1 of Embodiment 1. Components similar to those in Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted.

[0079] The second data may include the second image as well as data related to the second image. In Embodiment 1 described above, the data related to the second image includes, for example, data relating to the authentication of the person (visitor H2) in the second image. On the other hand, in this Modification 1, the data related to the second image includes data relating to the body surface temperature of the person (visitor H2) in the second image. This will be explained in more detail below.

[0080] The second imaging system 62 in this modified example includes a visible light camera and a thermal camera. The visible light camera and the thermal camera are positioned so that at least a portion of their respective imaging ranges coincide. The visible light camera generates a second image of the object to be imaged (visitor H2). The thermal camera generates surface temperature distribution data of the object to be imaged. The image output unit 43 outputs, for example, data obtained by superimposing the second image and the surface temperature distribution data so that they coincide in terms of time axis and space, as second data. Alternatively, the image output unit 43 outputs, for example, second data including the second image and surface temperature distribution data separate from the second image.

[0081] When the second data is output to the dwelling terminal 3, the display unit 38 of the dwelling terminal 3 displays the data corresponding to the second data. That is, the display unit 38 displays, for example, data that superimposes the second image and the surface temperature distribution data, or it displays the second image and the surface temperature distribution data separately with their time axes aligned. This allows resident H3 to estimate whether visitor H2 has a fever.

[0082] Furthermore, the data associated with the second image may include data relating to at least one of the following: authentication of the person in the second image, and the body surface temperature of the person in the second image.

[0083] The second imaging system 62 may include only a thermal camera among a visible light camera and a thermal camera. In other words, the second image may be an image captured by a thermal camera.

[0084] (Other modifications of Embodiment 1) The following lists other modifications of Embodiment 1. These modifications may be implemented in appropriate combinations. Furthermore, these modifications may be implemented in appropriate combinations with the above-described Modification 1.

[0085] In Embodiment 1, the object to be imaged by the first imaging system 61 and the object to be imaged by the second imaging system 62 are different. In contrast, the object to be imaged by the first imaging system 61 and the object to be imaged by the second imaging system 62 may be the same, as long as the first image captured by the first imaging system 61 is different from the second image captured by the second imaging system 62. For example, the first image may be an image of the object to be imaged (visitor H2, etc.) taken from the front, and the second image may be an image of the object to be imaged taken from the side, above, or behind.

[0086] The number of imaging systems is not limited to two, such as the first imaging system 61 and the second imaging system 62, but may be three or more. The image output unit 43 of the information terminal 1 may output image data based on at least one data from among three or more data generated by each of the three or more imaging systems.

[0087] The imaging system is not limited to capturing people. The imaging target may be, for example, the space surrounding a visitor H2. This allows, for example, a resident H3 to determine the number of people and the quantity of luggage in the space by viewing the images captured by the imaging system.

[0088] The multiple imaging systems include at least a first imaging system 61 and a second imaging system 62. At least one of the multiple imaging systems may be a night vision camera.

[0089] In Embodiment 1, when an operation is performed on the information terminal 1, the image output unit 43 outputs image data, and the image data is displayed on the display unit 38 of the dwelling terminal 3. However, the image output unit 43 may also output image data and the image data may be displayed on the display unit 38 of the dwelling terminal 3 at other times as well. For example, even if no operation is performed on the information terminal 1, the image output unit 43 may output image data and the image data may be displayed on the display unit 38 of the dwelling terminal 3 in response to an operation on the operation unit 32 of the dwelling terminal 3.

[0090] The display unit 38 of the dwelling terminal 3 may display image data based on both the first data and the second data. Specifically, the display unit 38 may display both the first image and the second image simultaneously. For example, the screen of the display unit 38 may be divided into two, with the first image displayed on one screen and the second image on the other. The size ratio of the first image and the second image may also be set by the setting unit 45.

[0091] Whether the image output unit 43 outputs image data based on the first data, the second data, or both may be set by an operation on the operation unit 12 of the information terminal 1. Alternatively, it may be set by a mobile terminal or personal computer or other terminal held by resident H3 or manager H1.

[0092] When display devices such as information terminal 1 and dwelling terminal 3 display image data based on first data, this does not mean that they are limited to displaying only the first image included in the first data, or an image obtained by processing the first image. For example, they may also display information such as the date and time of shooting and the location of shooting.

[0093] When display devices such as information terminal 1 and dwelling terminal 3 display image data based on the second data, this does not mean that they are limited to displaying only the second image included in the second data, or an image obtained by processing the second image. For example, they may also display information such as the date and time of shooting, the location of shooting, and data related to the authentication of people in the second image.

[0094] The image output unit 43 may output image data to a mobile device such as a smartphone or tablet owned by resident H3, for example.

[0095] The orientation (angle of view and elevation angle) of the camera of the second imaging system 62 may be changed in response to operations performed on the operation unit 12 of the information terminal 1.

[0096] The lobby intercom 2 is a device installed at the entrance of a multi-unit building, but at least some of the functions of the lobby intercom 2 in Embodiment 1 may be realized by a device other than the lobby intercom 2.

[0097] The dwelling unit terminal 3 is a device installed in a facility such as a dwelling unit, but at least some of the functions of the dwelling unit terminal 3 in Embodiment 1 may be realized by a device other than the dwelling unit terminal 3.

[0098] At least some of the functions of the intercom system 100 can be realized by a program, or a non-temporary recording medium on which the program is recorded. A program according to one embodiment is a program that causes one or more processors to execute the functions of an information terminal 1. The program may be recorded on a non-temporary recording medium that can be read by a computer.

[0099] One embodiment of the program is a program that causes an information terminal 1 to perform call processing, first input processing, second input processing, and image output processing. The information terminal 1 is installed in a complex facility that includes multiple facilities. Call processing is the process of establishing communication for calls with multiple dwelling terminals 3 installed in multiple facilities. First input processing is the process of receiving input of first data, including a first image captured by the first imaging system 61, from a first imaging system 61 installed in the complex facility. Second input processing is the process of receiving input of second data, including a second image captured by the second imaging system 62, from a second imaging system 62 installed in the complex facility. Image output processing is the process of outputting image data based on at least one of the first data and the second data.

[0100] The intercom system 100 in this disclosure includes a computer system. The computer system mainly consists of a processor and memory as hardware. At least a part of the functions of the intercom system 100 in this disclosure are realized by the processor executing a program recorded in the memory of the computer system. The program may be pre-recorded in the memory of the computer system, provided via a telecommunications line, or provided on a non-temporary recording medium such as a memory card, optical disk, or hard disk drive that can be read by the computer system. The processor of the computer system consists of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large-scale integrated circuit (LSI). The integrated circuits such as ICs and LSIs referred to here are named differently depending on the degree of integration, and include integrated circuits called system LSIs, VLSIs (Very Large Scale Integration), or ULSIs (Ultra Large Scale Integration). Furthermore, FPGAs (Field-Programmable Gate Arrays) that are programmed after the manufacture of the LSI, or logic devices that allow for the reconfiguration of junction relationships or circuit compartments within the LSI, can also be used as processors. Multiple electronic circuits may be integrated onto a single chip or distributed across multiple chips. Multiple chips may be integrated onto a single device or distributed across multiple devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller also consists of one or more electronic circuits, including semiconductor integrated circuits or large-scale integrated circuits.

[0101] Furthermore, it is not essential that the multiple functions of each device in the intercom system 100 be integrated into a single device. For example, it is not essential that the multiple functions of the information terminal 1 be integrated into a single device. The components of the information terminal 1 may be distributed across multiple devices. Moreover, at least some of the functions of the intercom system 100, for example, some of the functions of the authentication unit 49, may be implemented by the cloud (cloud computing), etc.

[0102] Conversely, in Embodiment 1, at least some of the functions of the intercom system 100, which are distributed across multiple devices, may be consolidated into a single device. For example, functions that are distributed between the first imaging system 61 and the information terminal 1 may be consolidated into a single device.

[0103] (Embodiment 2) The intercom system 100 according to Embodiment 2 will be described below with reference to Figures 1, 5, and 6. Components similar to those in Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted. Furthermore, each modification of Embodiment 1 may be appropriately applied to Embodiment 2. In addition, at least some of the functions of the intercom system 100 of Embodiment 2 can be realized by a program or a non-temporary recording medium on which a program is recorded.

[0104] In this embodiment, as in Embodiment 1, it is assumed that the collective facility is a residential apartment building. In this embodiment, it is also assumed that the information terminal 1 is installed in the manager's office of the collective facility. The information terminal 1 is used by the manager H1 of the collective facility. The first microphone 81 and the second microphone 82 (see Figure 1) are omitted.

[0105] The first imaging system 61 is installed in a different space from the space where the second imaging system 62 is installed. As shown in Figure 5, the first imaging system 61 is positioned to capture images of the caretaker H1 in the caretaker's room. The second imaging system 62 is positioned to capture images of the visitor H2 in front of the lobby intercom 2. The second imaging system 62 is installed independently of the lobby intercom 2. However, the second imaging system 62 may be incorporated into the lobby intercom 2.

[0106] The first sound input unit 46 receives input of first sound data, which is obtained by converting the sound picked up by the microphone 16 of the information terminal 1 into an electrical signal. The second sound input unit 47 receives input of second sound data, which is obtained by converting the sound picked up by the microphone 26 of the lobby intercom 2 into an electrical signal.

[0107] The target of the image output unit 43 to which it provides (outputs) image data is the lobby intercom 2 and the dwelling unit terminal 3. When the image output unit 43 outputs image data to the lobby intercom 2, the image output unit 43 outputs image data based on the first data, that is, image data based on the first image of the building manager H1.

[0108] The communication unit 44 of the information terminal 1 has the function of establishing communication for communication between the information terminal 1 and the multiple dwelling terminals 3, and between the information terminal 1 and the lobby intercom 2. Specifically, communication for communication is established when a call start signal indicating an instruction to start a call is exchanged between the information terminal 1 and the multiple dwelling terminals 3, or between the information terminal 1 and the lobby intercom 2.

[0109] When communication for a conversation is taking place between the information terminal 1 and the lobby intercom 2, if first data is input from the first imaging system 61 to the first input unit 41, the information terminal 1 outputs the first data to the lobby intercom 2 via the communication IF 11. The display unit 28 of the lobby intercom 2 displays image data based on the first data, and the speaker 27 plays first sound data. Also, when communication for a conversation is taking place between the information terminal 1 and the lobby intercom 2, if second data is input from the second imaging system 62 to the second input unit 42, the display unit 18 of the information terminal 1 displays image data based on the second image of visitor H2, and the speaker 17 plays second sound data. Visitor H2 and manager H1 can communicate while viewing each other's images.

[0110] The operation flow of the intercom system 100 of this embodiment will be described below with reference to Figure 6. Note that the sequence diagram shown in Figure 6 is merely one example of the operation flow of the intercom system 100, and the order of processing may be changed as appropriate, or processing may be added or omitted as appropriate.

[0111] Visitor H2 enters the building and operates the control panel 22 of the lobby intercom 2. This allows visitor H2 to specify the apartment number of the apartment they wish to visit (Step S1). The lobby intercom 2 then outputs a designated signal containing the information of the specified apartment number to the information terminal 1 (Step S2). The information terminal 1 notifies the building manager H1 of visitor H2's arrival, for example, by emitting a sound from the speaker 17.

[0112] The designated signal is also a signal to call the building manager H1. The building manager H1 responds to the call, for example, by picking up the receiver of the information terminal 1 (step S3). Then, communication is established between the lobby intercom 2 and the information terminal 1. The information terminal 1 also outputs a call signal to the dwelling terminal 3 among the multiple dwelling terminals 3 that is associated with the dwelling number specified by the designated signal (step S4).

[0113] Furthermore, when manager H1 responds to the call, information terminal 1 causes the first imaging system 61 and the second imaging system 62 to start imaging (step S5). At the same time, the microphone 26 of the lobby intercom 2 and the microphone 16 of information terminal 1 each start sound acquisition processing to capture sound and convert it into electrical signals (steps S5, S6). Information terminal 1 plays the image and voice of visitor H2, and lobby intercom 2 plays the image and voice of manager H1. This allows manager H1 and visitor H2 to communicate (step S7).

[0114] When a call signal is output to the dwelling terminal 3 in step S4, the dwelling terminal 3 notifies resident H3 that visitor H2 has arrived, for example by emitting a sound from speaker 37. Resident H3 responds to the call by, for example, operating the operation unit 32 of the dwelling terminal 3 (step S8). The dwelling terminal 3 then outputs a request signal to the information terminal 1 to request image data and sound data (step S9).

[0115] Information terminal 1 acquires first data and second data from the first imaging system 61 and the second imaging system 62, and outputs image data based on at least one of the first data and the second data to the dwelling terminal 3 (steps S10, S11). In addition, information terminal 1 acquires first sound data and second sound data from the microphone 26 of the lobby intercom 2 and the microphone 16 of information terminal 1, and outputs at least one of the first sound data and the second sound data (sound data) to the dwelling terminal 3 (steps S10, S11).

[0116] The dwelling terminal 3 displays image data on the display unit 38 and plays sound data on the speaker 37 according to the settings made by the setting unit 45 (step S12). For example, according to the settings, the display unit 38 initially displays a second image of visitor H2, and each time a specific operation is performed on the operation unit 32, it alternately displays the first image and the second image. Also, for example, when visitor H2 is speaking, second sound data is input to the dwelling terminal 3, and when manager H1 is speaking, first sound data is input to the dwelling terminal 3, so the speaker 37 plays the sound data that was most recently input. Preferably, the output of the first sound data and the second sound data in the sound output unit 48 can be switched by operating the operation unit 32 of the dwelling terminal 3 or the operation unit 12 of the information terminal 1. Also, by muting the microphone 16, the first sound data may not be output, and by muting the microphone 26, the second sound data may not be output.

[0117] Next, the building manager H1 performs a predetermined operation on the information terminal 1, thereby disconnecting communication between the information terminal 1 and the lobby intercom 2, and establishing communication between the information terminal 1 and the dwelling unit terminal 3. This enables communication between the building manager H1 and resident H3 (step S13). Specifically, the information terminal 1 plays the voice (or image and voice) of resident H3, and the dwelling unit terminal 3 plays the image and voice of the building manager H1. The building manager H1 inquires with resident H3 whether it is permissible to unlock the entrance door of the apartment complex (step S14). If resident H3 permits unlocking, the building manager H1 operates the operation unit 12 of the information terminal 1, which causes the lock control unit 50 to drive the electric lock installed on the entrance door D1, unlocking the entrance door D1. This allows the visitor H2 to pass through the entrance door D1 and proceed to the dwelling unit where resident H3 is located.

[0118] Furthermore, the call can be terminated by operating the control unit 32 of the dwelling terminal 3 or the control unit 12 of the information terminal 1. In other words, the communication for the call between the information terminal 1 and the dwelling terminal 3 can be disconnected by operating the control unit 32 or the control unit 12. Alternatively, the communication for the call may be disconnected when the entrance door D1 is unlocked.

[0119] Furthermore, building manager H1 can establish communication between the lobby intercom 2 and the dwelling unit terminal 3 by performing a predetermined operation on information terminal 1. This enables communication between visitor H2 and resident H3. For example, by operating information terminal 1, it is possible to switch between information terminal 1 communicating with dwelling unit terminal 3 for communication purposes, or information terminal 1 communicating with lobby intercom 2 for communication purposes.

[0120] (Embodiment 3) The intercom system 100 according to Embodiment 3 will be described below with reference to Figure 7. Components similar to those in Embodiment 1 are denoted by the same reference numerals and their descriptions are omitted. Furthermore, each modification of Embodiment 1 and the configuration of Embodiment 2 may be appropriately applied to Embodiment 3. In addition, at least some of the functions of the intercom system 100 of Embodiment 3 can be realized by a program or a non-temporary recording medium on which a program is recorded.

[0121] The intercom system 100 of this embodiment differs from Embodiment 1 in that it further includes a control device 9. The control device 9 controls communication between the lobby intercom 2, the dwelling unit terminal 3, and the information terminal 1. More specifically, the control device 9 relays communication between the lobby intercom 2, the dwelling unit terminal 3, and the information terminal 1.

[0122] In this embodiment, as in Embodiment 1 or Embodiment 2, the image output unit 43 of the information terminal 1 can output not only image data based on the first data, but also image data based on the second data, or image data based on both the first and second data. This improves convenience for users who refer to the image data.

[0123] (summary) Based on the embodiments described above, the following aspects are disclosed.
