[Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-15974 Summary of the Invention [Problem to be solved by the invention]

[0004] When an intercom system is installed in a multi-unit facility such as an apartment building, the door phone handset and intercom master unit are installed in facilities within the multi-unit facility, such as residences. A lobby unit is also installed in the lobby of the multi-unit facility. When a visitor arrives at the multi-unit facility, the visitor operates the lobby unit, enabling communication between the lobby unit and the intercom master unit. After a conversation between the visitor using the lobby unit and a resident using the intercom master unit, the resident operates the intercom master unit to unlock the lobby's electronic lock. Once the lobby's electronic lock is unlocked, the visitor moves from the lobby to the residence within the multi-unit facility. In recent years, services have been offered that allow the visitor (deliverer) to deliver packages and other items without meeting the resident by leaving them in front of the residence. In such services, the lobby's electronic lock needs to be unlocked even when there is no conversation between the visitor and the resident. It is also necessary to ensure that the lobby's electronic lock is unlocked properly.

[0005] The present disclosure has been made in consideration of these circumstances, and its purpose is to provide a technology that can reliably unlock an electronic lock in a lobby even without a call between a visitor and a resident. [Means for solving the problem]

[0006] To solve the above problem, an intercom device according to one aspect of the present disclosure includes an imaging unit that captures an image of an object, and a display unit that displays an image including the object captured by the imaging unit. When the imaging unit captures an image of the object, the object overlaps a first area of ​​the display unit, and the display unit displays the image in a second area different from the first area.

[0007] Another aspect of the present disclosure is also an intercom device. The device includes an imaging unit that captures an image of an imaging target and a display unit. When the imaging unit captures an image of the imaging target, the imaging target should be positioned so as to overlap a partial area of ​​the display unit, and when the imaging unit captures an image of the imaging target, the display unit displays a guide indicating the partial area.

[0008] Any combination of the above components, and conversion of the present disclosure into a method, device, system, recording medium, computer program, etc., are also valid aspects of the present disclosure. [Effects of the Invention]

[0009] According to the present disclosure, the electronic lock in the lobby can be reliably unlocked even without a call between the visitor and the resident. [Brief explanation of the drawings]

[Figure 3] FIG. 3 is a diagram showing the data structure of a database stored in the storage unit of FIG. 2(c). [Figure 4]Figures 4(a)-(b) are diagrams showing an overview of the lobby machine in Figure 2(a). [Figure 5] Figures 5(a)-(b) are diagrams showing an overview of the lobby machine in Figure 2(a). DETAILED DESCRIPTION OF THE INVENTION

[0011] Before describing the present disclosure in detail, an overview will be provided. The embodiment relates to an intercom system installed in a collective facility such as an apartment building or condominium. A collective facility includes a plurality of residences and other facilities, and people can enter and exit through at least one lobby (common entrance). When a visitor operates a lobby unit such as a lobby intercom installed in the lobby, a call is made to a facility master unit installed in the facility they are visiting. In response to the call, a resident of the facility operates the facility master unit to confirm the visitor. When the resident operates the facility master unit after confirming the visitor, the facility master unit transmits a signal (hereinafter referred to as an "unlock instruction") to the lobby unit to unlock the electronic lock in the lobby. Upon receiving the unlock instruction, the lobby unit unlocks the electronic lock.

[0012] In such intercom systems, the electronic lock is unlocked when the resident confirms the visitor based on communication between the facility master unit and the lobby unit. In recent years, services have been offered that allow the visitor (delivery person) to deliver packages and other items without meeting the resident by leaving the package in front of the residence. Such services are available even when the resident is not at home. In such cases, it is necessary to unlock the electronic lock in the lobby even if the resident has not confirmed the visitor. On the other hand, when unlocking the electronic lock in the lobby in a situation where the resident has not confirmed the visitor, it is necessary to ensure safety.

[0013] To ensure safety while unlocking the electronic lock in the lobby when the resident has not confirmed the visitor, the server (management server) of the intercom system according to this embodiment generates information about the visitor's destination as an authentication code and transmits the authentication code to the visitor's mobile terminal device. The authentication code is, for example, a barcode or a QR code (registered trademark), and includes information identifying the visitor's destination, the visitor, and the baggage. The visitor has the lobby device capture an image of the authentication code displayed on the mobile terminal device. The lobby device acquires the authentication code information based on the captured authentication code. The lobby device transmits the authentication code information to the server (control server). The control server requests the management server to authenticate the authentication code information. In response to a request from the control server, the management server authenticates the authentication code information and transmits the authentication result to the control server. If the authentication result indicates success, the control server transmits an unlock instruction to the lobby device. Upon receiving the unlock instruction, the lobby device unlocks the electronic lock.

[0014] 1 shows the configuration of an intercom system 1000. The collective facility 100 includes a facility 110. Although only one facility 110 is shown here, the collective facility 100 includes multiple facilities 110. An example of the collective facility 100 is an apartment building, and an example of the facility 110 is a residence. The intercom system 100 includes a first lobby unit 200a and a second lobby unit 200b collectively referred to as lobby unit 200, a control device 300, a gateway 310, a network 320, a first electronic lock 330a and a second electronic lock 330b collectively referred to as electronic lock 330, a first common area trunk line 350a and a second common area trunk line 350b collectively referred to as common area trunk line 350, an occupied trunk line 360, a facility master unit 400, a facility slave unit 480, a management server 500, a mobile terminal device 600, and a control server 700. The facility master unit 400 and the facility slave unit 480 are installed in the facility 110. In addition, a facility master unit 400 and a facility slave unit 480 are installed in each of the multiple facilities 110 included in the collective facility 100. Below, (1) the basic operation of the intercom system 1000, (2) unlocking control in the intercom system 1000, (3) imaging of the authentication code in the lobby unit 200 (part 1), and (4) imaging of the authentication code in the lobby unit 200 (part 2) will be explained in order.

[0015] (1) Basic operation of the intercom system 1000 The collective facility 100 (apartment building) has two lobbies (common entrances), with a first lobby unit 200a and a first electronic lock 330a installed in the first lobby, and a second lobby unit 200b and a second electronic lock 330b installed in the second lobby. The number of lobbies, lobby units 200, and electronic locks 330 in the collective facility 100 is not limited to two. Generally, the number of lobbies, lobby units 200, and electronic locks 330 are the same. The first electronic lock 330a locks and unlocks the door to the first lobby. The second electronic lock 330b locks and unlocks the door to the second lobby. Under normal conditions, the first electronic lock 330a and the second electronic lock 330b are locked.

[0016] The lobby device 200 is also called a lobby intercom. Figures 2(a)-(c) show the configurations of the lobby device 200, management server 500, and control server 700. Figure 2(a) shows the configuration of the lobby device 200. The lobby device 200 includes an imaging unit 212, a microphone 214, a speaker 218, a display unit 220, an operation unit 222, an IF unit 230, a processing unit 240, and a first communication unit 250a, a second communication unit 250b, and a third communication unit 250c, collectively referred to as a communication unit 250.

[0017] The imaging unit 212 is used to capture images of visitors and includes a solid-state imaging element such as a CMOS (Complementary Metal Oxide Semiconductor) image sensor or a CCD (Charge Coupled Device) image sensor. The solid-state imaging element outputs a photoelectrically converted video signal to the IF unit 230. The IF unit 230 performs various signal processing on the video signal from the imaging unit 212. Well-known techniques may be used for the various signal processing, and therefore a description thereof will be omitted here. The IF unit 230 outputs the video signal that has undergone signal processing (hereinafter also referred to as the "video signal") to the processing unit 240.

[0018] The microphone 214 and speaker 218 are user interfaces that allow visitors to talk to residents. The microphone 214 collects the visitor's voice, converts it into an electrical signal, and outputs it to the IF unit 230. The speaker 218 reproduces the electrical signal from the IF unit 230 and outputs it as audio. The IF unit 230 receives the electrical signal from the microphone 214 and converts it into a signal in a format for transmission (hereinafter referred to as an "audio signal"). The IF unit 230 outputs the audio signal to the processing unit 240. Meanwhile, the IF unit 230 inputs the audio signal from the processing unit 240 and converts the audio signal into an electrical signal. The IF unit 230 outputs the electrical signal to the speaker 218.

[0019] Display unit 220 displays messages and the like. IF unit 230 receives a message signal from processing unit 240 and outputs the message signal to display unit 220. The message signal may be generated in lobby device 200. IF unit 230 may also output a video signal received from imaging unit 212 to display unit 220, and display unit 220 may display a video based on the video signal.

[0020] The operation unit 222 is a user interface for accepting operations by the visitor, such as a call button. When the operation unit 222 accepts the number of the facility 110 that the visitor plans to visit from the visitor, the operation unit 222 outputs a call request to the IF unit 230. The IF unit 230 outputs the call request to the processing unit 240.

[0021] The processing unit 240 controls the operation of the lobby unit 200. The processing unit 240 is connected to the first communication unit 250a through the third communication unit 250c. The first communication unit 250a is connected to the control device 300 via the common trunk line 350, and performs communication with the facility base unit 400 via the control device 300. Specifically, the first communication unit 250a transmits and receives the above-mentioned call requests, video signals, audio signals, and message signals to and from the facility base unit 400, but the signals transmitted and received are not limited to these. Figures 2(b) and (c) will be described later, and we will return to Figure 1.

[0022] The first lobby device 200a is connected to the control device 300 via a first common area trunk line 350a, and the second lobby device 200b is connected to the control device 300 via a second common area trunk line 350b. The control device 300 is installed in a common space such as a machine room or a caretaker's room, and relays signals between the lobby device 200 and the facility main device 400. The common area trunk line 350 and the occupied trunk line 360 ​​are transmission paths for transmitting call signals from the lobby device 200, response signals from the facility main device 400, and the like. The common area trunk line 350 and the occupied trunk line 360 ​​transmit the above-mentioned call requests, video signals, audio signals, and message signals.

[0023] The facility base unit 400 is installed in the facility 110 and is also called a home information panel, a dwelling unit unit, a dwelling unit terminal, a room base unit, or a home base unit. Similar to the control device 300, the facility base unit 400 includes a microphone (not shown), a speaker (not shown), a display unit (not shown), an operation unit (not shown), an IF unit (not shown), a processing unit (not shown), and a communication unit (not shown). The display unit displays the image captured by the imaging unit 212 of the lobby unit 200.

[0024] The communication unit is connected to the control device 300 via the occupied trunk line 360, and communicates with the lobby device 200 via the control device 300. A processing unit is connected to the communication unit, and the processing unit controls the operation of the facility master device 400. An IF unit is connected to the processing unit, and a microphone, speaker, display unit, and operation unit are connected to the IF unit.

[0025] The processing unit receives a call request, a video signal, and an audio signal from the lobby unit 200 via the communication unit. Upon receiving the call request, the processing unit outputs a ring tone from the speaker via the IF unit. Subsequently, the processing unit displays an image reproduced from the video signal on the display unit via the IF unit, and outputs an audio reproduced from the audio signal from the speaker via the IF unit. When a resident who hears the ring tone responds to the call by operating the operation unit, the processing unit causes the communication unit to execute communication with the lobby unit 200. As a result, a call is established between the visitor operating the lobby unit 200 and the resident operating the facility main unit 400 by communicating video and audio signals between the communication units 250 and 250. Here, as an example, a call is established between the visitor operating the first lobby unit 200a and the resident operating the facility main unit 400.

[0026] When the resident decides to unlock the first electronic lock 330a through a call with the visitor, the resident operates the operation unit to input an unlock command. When the processing unit receives the unlock command from the operation unit via the IF unit, it generates a signal indicating the unlock command (hereinafter referred to as the "unlock command"). The transmission unit transmits the unlock command to the first lobby terminal 200a via the occupied trunk line 360, the control device 300, and the first common area trunk line 350a.

[0027] The first communication unit 250a of the first lobby device 200a receives the unlocking instruction. The processing unit 240 outputs the unlocking instruction received by the first communication unit 250a to the second communication unit 250b. The second communication unit 250b is connected to the first electronic lock 330a and transmits the unlocking instruction to the first electronic lock 330a. When the first electronic lock 330a receives the unlocking instruction from the first lobby device 200a, it executes unlocking. The first electronic lock 330a executes locking after a certain period of time has passed since unlocking. The second lobby device 200b and the second electronic lock 330b operate in the same way. In this way, the lobby device 200 is installed in the lobby of the destination device and executes locking or unlocking the lobby.

[0028] A facility slave unit 480 installed outside the entrance of the facility 110 is connected to the facility master unit 400. The facility slave unit 480 is also called a door intercom or a room slave unit. The facility slave unit 480 may be configured in the same manner as the lobby unit 200, and therefore a description thereof will be omitted here. Therefore, a call is made between a visitor operating the facility slave unit 480 and a resident operating the facility master unit 400.

[0029] (2) Unlocking Control in the Intercom System 1000 As explained in (1), the electronic lock 330 is unlocked by the resident's operation. Meanwhile, a service is provided in which a visitor (delivery person) can deliver a package or other item without meeting the resident by leaving the package or other item in front of the residence. Since such a service is provided even when the resident is not at home, it is necessary to unlock the electronic lock in the lobby without the resident's operation. Furthermore, even when such unlocking is performed, safety must be ensured.

[0030] The process of this embodiment for realizing this will be explained below in accordance with steps (i) to (x) in FIG. 1, using FIG. 1 and FIGS. 2(a) to 2(c). (i) The management server 500 is a server managed by the service provider, and manages information about destinations. A destination is a delivery destination for a package or a service provider. An example of a destination is the facility 110 included in the complex 100. FIG. 2(b) shows the configuration of the management server 500. The management server 500 includes a communication unit 510, a processing unit 520, and a memory unit 530, and the processing unit 520 includes a generation unit 522 and an authentication unit 524.

[0031] The communication unit 510 is connected to the network 320. The communication unit 510 receives address information of the location where the service is to be provided and information identifying the service from a communication device (not shown) of the service provider via the network 320. The information identifying the service is information identifying the package to be delivered (hereinafter referred to as "authentication number") when the service provided is package delivery.

[0032] The generation unit 522 receives from the communication unit 510 the address information of the location where the service is to be provided and information identifying the service (authentication number). The memory unit 530 stores the correspondence between the address information and a combination of a property ID, building information, and room number. The property ID is identification information for identifying the complex facility 100, and the building information is identification information for identifying a building if the complex facility 100 has multiple buildings. The room number is identification information for identifying the facility 110. The generation unit 522 obtains the combination of the property ID, building information, and room number from the received address information by referring to the correspondence in the memory unit 530.

[0033] The generation unit 522 generates an authentication code including building information, room number, contractor classification, and authentication number. The contractor classification is identification information for identifying the service provider. The authentication code is, for example, a barcode or QR code (registered trademark). The building information and room number are also referred to as information about the destination. The generation unit 522 outputs the generated authentication code to the communication unit 510, and stores the combination of the property ID, building information, room number, contractor classification, and authentication number in the memory unit 530.

[0034] (ii) Communication unit 510 transmits the authentication code generated by generation unit 522 to mobile terminal device 600 via network 320. Mobile terminal device 600 is a wireless communication device such as a smartphone. Mobile terminal device 600 is carried by a visitor (delivery person) who visits the destination.

[0035] (iii) The mobile terminal device 600 receives the authentication code from the management server 500. The visitor travels to the collective facility 100 and, upon arriving at the collective facility 100, proceeds to the first lobby. The visitor operates the mobile terminal device 600 to display the authentication code on the display unit of the mobile terminal device 600. The visitor operates the operation unit 222 of the lobby device 200 to input an instruction to change to the unlock control mode. Here, (1) the operation of the lobby device 200 in the basic operation of the intercom system 1000 is called the normal mode. When the processing unit 240 receives the instruction to change to the unlock control mode from the operation unit 222 via the IF unit 230, it changes the mode of the lobby device 200 from the normal mode to the unlock control mode. Thereafter, the visitor holds the authentication code displayed on the display unit of the mobile terminal device 600 over the imaging unit 212, causing the imaging unit 212 to capture an image of the authentication code.

[0036] (iv) The imaging unit 212 captures an image of the authentication code displayed on the display unit of the mobile terminal device 600. When in the unlock control mode, the reception unit 242 of the processing unit 240 receives the authentication code captured by the imaging unit 212 via the IF unit 230. The processing unit 240 acquires authentication code information by reading the authentication code. The authentication code information is information contained in the authentication code. The processing unit 240 outputs the authentication code information to the third communication unit 250c. The third communication unit 250c transmits the authentication code information to the gateway 310. The gateway 310 may be connected to the control device 300, and the first communication unit 250a may transmit the authentication code information to the control device 300, and the control device 300 may transmit the authentication code information. In this case, the third communication unit 250c does not need to be provided in the lobby device 200.

[0037] The gateway 310 is located within the collective facility 100. The gateway 310 is also located between the lobby device 200 and the control server 700. The gateway 310 receives authentication code information from the first lobby device 200a. The gateway 310 transmits the authentication code information to the control server 700 via the network 320. At that time, the gateway 310 adds the MAC (Media Access Control) address of the gateway 310 to the authentication code information.

[0038] (v) The control server 700 is connected to each of the multiple collective facilities 100 and controls the unlocking of the lobby of each collective facility 100. FIG. 2(c) shows the configuration of the control server 700. The control server 700 includes a communication unit 710, a processing unit 720, and a memory unit 730, and the processing unit 720 includes a request unit 722, a reception unit 724, and an instruction unit 726. The communication unit 710 receives authentication code information and a MAC address from the gateway 310. The communication unit 710 outputs the authentication code information and the MAC address to the processing unit 720. The request unit 722 of the processing unit 720 receives the authentication code information and the MAC address from the communication unit 710.

[0039] The memory unit 730 stores a database. Figure 3 shows the data structure of the database stored in the memory unit 730. As shown in the figure, MAC addresses are associated with property IDs. The request unit 722 references the database stored in the memory unit 730 and acquires the property ID corresponding to the received MAC address. Returning to Figure 2, the request unit 722 requests the management server 500 to authenticate the authentication code information and the property ID via the communication unit 710 and the network 320.

[0040] (vi) The communication unit 510 of the management server 500 receives authentication code information and an authentication request for the property ID from the control server 700 via the network 320. The communication unit 510 outputs the authentication code information and the authentication request for the property ID to the processing unit 520. The authentication unit 524 of the processing unit 520 obtains a combination of the property ID, building information, room number, contractor classification, and authentication number from the authentication code information and the authentication request for the property ID. The authentication unit 524 also obtains a combination of the property ID, building information, room number, contractor classification, and authentication number stored in the memory unit 530. If these match, the authentication unit 524 determines that the authentication is successful; if they do not match, the authentication is unsuccessful. The management server 500 may use the MAC address of the gateway 310 as the property ID. In this case, the memory unit 530 of the control server 700 does not store a table correlating MAC addresses with property IDs.

[0041] (vii) The communication unit 510 of the management server 500 transmits the authentication result to the control server 700 via the network 320 .

[0042] (viii) The communication unit 710 of the control server 700 receives the authentication result from the management server 500 via the network 320. The communication unit 710 outputs the authentication result to the processing unit 720. The reception unit 724 of the processing unit 720 receives the authentication result from the management server 500. The instruction unit 726 determines to unlock if the authentication result received by the reception unit 724 indicates success. On the other hand, the instruction unit 726 determines not to unlock if the authentication result received by the reception unit 724 indicates failure. If the instruction unit 726 determines to unlock, it outputs an unlock instruction to the communication unit 710. The communication unit 710 transmits the unlock instruction to the gateway 310 via the network 320. The gateway 310 receives the unlock instruction from the control server 700. The gateway 310 broadcasts the unlock instruction. That is, the gateway 310 sends an unlock command to the first lobby device 200a and the second lobby device 200b.

[0043] (ix) The third communication unit 250c of the first lobby device 200a and the second lobby device 200b receives an unlocking instruction from the gateway 310. If the processing unit 240 of the first lobby device 200a receives an unlocking instruction within a predetermined period of time after outputting the authentication code information to the third communication unit 250c, it decides to unlock the first lobby device 200a. If the processing unit 240 decides to unlock, it outputs the unlocking instruction to the second communication unit 250b. The second communication unit 250b sends the unlocking instruction to the first electronic lock 330a. When the first electronic lock 330a receives the unlocking instruction from the first lobby device 200a, it executes the unlocking. On the other hand, the processing unit 240 of the second lobby device 200b does not receive an unlocking instruction within a predetermined period of time after outputting the authentication code information to the third communication unit 250c, so it decides not to unlock the second electronic lock 330b.

[0044] (x) When the first electronic lock 330a is unlocked, the visitor moves through the complex 100 to the facility 110 and places the package in front of the door of the facility 110, for example. This ends the package delivery service. The visitor operates the mobile terminal device 600 to input the completion of delivery. The mobile terminal device 600 sends a notification to the management server 500 via the network 320 informing the management server 500 of the completion of delivery.

[0045] (3) Imaging the authentication code on the lobby device 200 (part 1) The following provides a more detailed description of the imaging unit 212 of the lobby device 200 in (1) the basic operation of the intercom system 1000 and (2) the unlocking control in the intercom system 1000. FIGS. 4(a)-(b) show an overview of the lobby device 200. FIG. 4(a) shows the appearance of the lobby device 200. The lobby device 200 is provided with a rectangular display unit 220. The imaging unit 212 is disposed above the display unit 220, and an operation unit 222 is disposed below the display unit 220. The imaging unit 212 (1) captures an image of a visitor in the basic operation of the intercom system 1000, and (2) captures an image of an authentication code in the unlocking control in the intercom system 1000. (1) In the basic operation of the intercom system 1000, the imaging unit 212 is set as wide as possible to capture an image of the visitor regardless of the visitor's position.

[0046] FIG. 4(b) shows the appearance of the mobile terminal device 600. The mobile terminal device 600 is provided with a rectangular display unit 610. In (2) unlocking control in the intercom system 1000, an authentication code is displayed on the display unit 610. The planar image displayed on the display unit 610 of the mobile terminal device 600, which displays the authentication code, is the target of imaging by the imaging unit 212. The size of the authentication code displayed on the display unit 610 is small compared to the size of the visitor's face. Therefore, in order for the imaging unit 212 to accurately capture the authentication code, it is necessary to bring the mobile terminal device 600 close to the imaging unit 212. In such a situation, it is difficult to tell whether the authentication code is positioned in a position where the imaging unit 212 can capture an image. Here, the objective is to make it easy to tell whether the authentication code is captured by the imaging unit 212 in (2) unlocking control in the intercom system 1000.

[0047] 5(a)-(b) show an overview of the lobby machine 200. FIG. 5(a) shows the portable terminal device 600 when the imaging unit 212 is caused to capture an image of an authentication code. When the imaging unit 212 captures an image of the portable terminal device 600, the portable terminal device 600 overlaps the first area 260 of the display unit 220. Here, since the size of the portable terminal device 600 varies depending on the model, the first area 260 is set to be larger than the portable terminal device 600 in consideration of the larger size of the portable terminal device 600. In addition, a second area 262 different from the first area 260 is set on the display unit 220. The second area 262 is an area in which the portable terminal device 600 does not overlap the display unit 220 when the imaging unit 212 captures an image of the portable terminal device 600.

[0048] The processing unit 240 displays an image including the mobile terminal device 600 captured by the imaging unit 212 in the second area 262 of the display unit 220. The display unit 220 displays the image in the second area 262 as shown in FIG. 5(a). For example, an authentication code is displayed in the second area 262. Based on the authentication code displayed in the second area 262, the visitor checks whether the authentication code has been captured by the imaging unit 212. The processing unit 240 executes the processing described in (2) Unlocking Control in the Intercom System 1000 based on the image captured by the imaging unit 212 that includes the mobile terminal device 600 (authentication code). The processing described in (2) Unlocking Control in the Intercom System 1000 is processing other than calling.

[0049] As described above, (1) in the basic operation of the intercom system 1000, the imaging unit 212 can also capture an image of a visitor other than the mobile terminal device 600 (authentication code). In this case, the first area 260 and the second area 262 are not set on the display unit 220. The first area 260 executes a call to the visitor based on an image including the visitor captured by the imaging unit 212.

[0050] (4) Imaging the authentication code on the lobby device 200 (part 2) (4) Imaging of the authentication code on the lobby device 200 (part 2) is intended to explain a situation similar to that of (3) Imaging of the authentication code on the lobby device 200 (part 1). (2) In unlocking control in the intercom system 1000, the processing unit 240 displays a frame-shaped guide 270 as shown in Fig. 5(b) on the display unit 220. The guide 270 indicates a partial area of ​​the lobby device 200 that the mobile terminal device 600 should be placed in when the imaging unit 212 images the mobile terminal device 600 (authentication code).

[0051] The visitor points the mobile terminal device 600, which has the authentication code displayed on the display unit 610, toward the lobby terminal 200, and aligns the mobile terminal device 600 with the guide 270 displayed on the display unit 220, causing the imaging unit 212 to capture an image of the mobile terminal device 600. As a result, the imaging unit 212 captures an image of the authentication code, and the processing unit 240 executes the processing described in (2) Unlocking Control in the Intercom System 1000 based on the image captured by the imaging unit 212 that includes the mobile terminal device 600 (authentication code).

[0052] The subject of the device, system, or method of the present disclosure includes a computer. The computer executes a program to realize the functions of the subject of the device, system, or method of the present disclosure. The computer includes, as its main hardware component, a processor that operates according to the program. The processor may be of any type, as long as it can realize the functions by executing the program. The processor may be composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integration (LSI). The electronic circuits may be integrated into a single chip or may be provided on multiple chips. The multiple chips may be integrated into a single device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium, such as a computer-readable ROM, optical disk, or hard disk drive. The program may be pre-stored on the recording medium or may be supplied to the recording medium via a wide-area communication network, including the Internet.

[0053] According to this embodiment, the mobile terminal device 600 causes the lobby device 200 to capture an image of an authentication code generated by the management server 500. If the management server 500 successfully authenticates the authentication code information acquired by the mobile terminal device 600, the lobby is unlocked. This allows the lobby electronic lock 330 to be unlocked even without a call between the visitor and the resident. Furthermore, since the management server 500 authenticates the authentication code information, the lobby electronic lock 330 can be safely unlocked even without a call between the visitor and the resident. Furthermore, the management server 500 manages the property ID, and the control server 700 requests the management server 500 to authenticate the authentication code information and the property ID. Therefore, authentication can be performed without including the property ID in the authentication code. Furthermore, since authentication is performed without including the property ID in the authentication code, an increase in the amount of information in the authentication code can be suppressed. Furthermore, since the MAC address of the gateway 310 is used as the property ID, processing can be simplified.

[0054] Furthermore, when the imaging unit 212 captures an image of the mobile terminal device 600 (authentication code), the mobile terminal device 600 displays an image including the authentication code in the second area 262, which is different from the first area 260 that overlaps the display unit 220, making it easy to see whether the authentication code has been captured by the imaging unit 212. Furthermore, since it is easy to see whether the authentication code has been captured by the imaging unit 212, the electronic lock 330 in the lobby can be reliably unlocked even without a call between the visitor and the resident. Furthermore, when the imaging unit 212 captures an image of the mobile terminal device 600 (authentication code), the mobile terminal device 600 displays a portion of the area that overlaps the display unit 220 as a guide 270, making it easy to see whether the authentication code has been captured by the imaging unit 212. Furthermore, since the guide 270 has a frame shape that surrounds the portion of the area, it can indicate where the mobile terminal device 600 should be placed.

[0055] Furthermore, since the imaging unit 212 captures a two-dimensional image displayed on the screen of the mobile terminal device 600, which also shows the authentication code, (2) it is possible to execute unlocking control in the intercom system 1000. Furthermore, the imaging unit 212 can also capture an image of a visitor, and the processing unit 240 executes a call to the visitor based on the image including the visitor captured by the imaging unit 212, so (1) it is possible to execute the basic operations of the intercom system 1000.

[0056] In this embodiment, the reading of a flat image displayed on the screen of the mobile terminal device 600 has been particularly described, but flat images printed or imprinted on a flat surface, such as a waybill or sticker attached to a package, can also be read in the same way, and these variations are naturally included in the scope of this disclosure.

[0062] The present disclosure has been described above based on examples. These examples are merely illustrative, and it will be understood by those skilled in the art that various modifications are possible in the combination of each component or each treatment process, and that such modifications are also within the scope of the present disclosure.

[0063] In this embodiment, a visitor operates the operation unit 222 of the lobby terminal 200 to input an instruction to change to the unlock control mode. However, this is not limited to this, and the change from the normal mode to the unlock control mode may be automatic, for example. The imaging unit 212 performs imaging using the first parameter set. The processing unit 240 includes a recognition unit, which recognizes through image recognition processing whether the image captured by the imaging unit 212 using the first parameter set contains an authentication code or not. Any known technology may be used for the image recognition processing. If the recognition unit recognizes that the image does not contain an authentication code, the imaging unit 212 uses the first parameter set, and if the recognition unit recognizes that the image contains an authentication code, the imaging unit 212 uses the second parameter set. This modification improves the convenience of visitors. [Explanation of symbols]
