[0011] The embodiments and modifications described below are merely examples of the present disclosure, and the present disclosure is not limited to the embodiments and modifications. Various modifications other than the following embodiments and modifications are possible according to the design, etc., as long as they do not deviate from the technical idea of ​​the present disclosure.

[0012] (Embodiment) Hereinafter, a display terminal as a display system 1 according to this embodiment and a system including the display terminal will be described with reference to FIGS.

[0013] (1) Overview In this embodiment, the display terminal serving as the display system 1 is an intercom master unit 10 provided in the intercom system 2 (see FIGS. 1 and 2).

[0014] 2, the intercom system 2 includes a plurality of (three in the illustrated example) intercom master units 10, a plurality of (three in the illustrated example) entrance slave units 20, a lobby intercom 30, a control device 40, and a management room device 50. In this embodiment, a case in which the intercom system 2 is used in an apartment building as the facility 5 will be described as an example.

[0015] The lobby intercom 30 is installed in a common area E1, such as a lobby of an apartment building. The apartment building has a plurality of dwelling units E2 in addition to the common area E1. The intercom master unit 10 is installed in each dwelling unit E2. The entrance slave unit 20 is installed, for example, at the exterior entrance of each dwelling unit E2.

[0016] The lobby intercom 30 and the intercom master unit 10 are configured to be able to communicate with each other via the control device 40. As a result, in the intercom system 2 according to this embodiment, calls can be made between the lobby intercom 30 and the intercom master unit 10. The intercom master unit 10 and the entrance door sub unit 20 are configured to be able to communicate with each other. Furthermore, the intercom master unit 10 and the management room device 50 are configured to be able to communicate with each other via the control device 40. In other words, the entrance door sub unit 20, the lobby intercom 30, and the management room device 50 are able to communicate with the intercom master unit 10, and correspond to the communication terminals of the present disclosure.

[0017] The lobby intercom 30 includes an imaging device. When a visitor performs a call operation, the lobby intercom 30 starts imaging the visitor with the imaging device. The lobby intercom 30 transmits data of the captured image to the intercom master unit 10 via the control device 40. Furthermore, the lobby intercom 30 transmits a control signal (call signal) for calling a resident in the dwelling unit E2 to the intercom master unit 10 via the control device 40. When a call with the intercom master unit 10 is enabled by an operation on the intercom master unit 10, the lobby intercom 30 transmits sound data including the visitor's voice to the intercom master unit 10 via the control device 40. When the lobby intercom 30 receives sound data of the operator of the intercom master unit 10 via the control device 40, it outputs sound (including the operator's voice) based on the received data.

[0018] When the intercom master unit 10 receives the image data from the lobby intercom 30, it displays the image captured by the lobby intercom 30 based on the received image data.

[0019] When the intercom master unit 10 is receiving a control signal (call signal) from the lobby intercom 30 (i.e., when a visitor is calling via the lobby intercom 30), a resident in unit E2 can make a call to the lobby intercom 30 or unlock the lobby door.

[0020] When the control device 40 receives a control signal (call signal) from the lobby intercom 30, it transmits the signal to the intercom master unit 10 to be called. Furthermore, when the control device 40 receives image data from the lobby intercom 30, it transmits the image data to the intercom master unit 10 to be called. When communication between the lobby intercom 30 and the intercom master unit 10 is possible, the control device 40 transmits and receives sound data including the voice of a visitor and sound data including the voice of the operator. Furthermore, the control device 40 locks and unlocks a door, for example, provided in the dwelling unit E2, in response to the operation of the intercom master unit 10.

[0021] The control device 40 is configured to be able to communicate with devices outside the facility 5. For example, the control device 40 can communicate with a weather server that provides a service of distributing weather data. In this case, the control device 40 receives meteorological information including the weather and precipitation probability of the area including the facility 5 from the weather server, and transmits the information to each intercom master unit 10.

[0022] The control device 40 controls an elevator control device 60 provided in the facility 5 according to instructions from the intercom master unit 10. The elevator control device 60 is a device that controls an elevator provided in the facility 5. When the control device 40 receives an instruction related to elevator control from the intercom master unit 10, it transmits a movement instruction to the elevator control device 60 to move the elevator to the floor where the dwelling unit E2 of the intercom master unit 10 is located.

[0023] Upon receiving the movement instruction, the elevator control device 60 controls the elevator so that the elevator moves to the specified floor.

[0024] The front door sub-unit 20 includes an imaging device. When a visitor performs a call operation, the front door sub-unit 20 starts imaging the visitor with the imaging device. The front door sub-unit 20 transmits data of the captured image to the intercom master unit 10. Furthermore, the front door sub-unit 20 transmits a control signal (call signal) to the intercom master unit 10 for calling a resident in the dwelling unit E2. When a call with the intercom master unit 10 is enabled by operating the intercom master unit 10, the front door sub-unit 20 transmits sound data to the intercom master unit 10. When the front door sub-unit 20 receives sound data including the voice of the operator of the intercom master unit 10, it outputs sound (including the operator's voice) based on the received data.

[0025] In this embodiment, each of the dwelling units E2 is equipped with a detector 70 and a sensor 75.

[0026] The detector 70 is, for example, a fire detector, a gas detector, etc. In the illustrated example, one detector 70 is shown, but in this embodiment, the dwelling unit E2 is provided with a plurality of detectors 70, such as the detector 70 as a fire detector, the detector 70 as a gas detector, etc. The detector 70 is provided with a detection unit that detects the presence or absence of an abnormality, a notification unit that notifies the detection of the abnormality when an abnormality is detected, and a communication unit. When an abnormality is detected, the communication unit of the detector notifies the intercom master unit 10 of information indicating that an abnormality has been detected as a detection result by wireless communication.

[0027] The sensor 75 is a sensor that detects the locking / unlocking of the front door of the dwelling unit E2, a sensor that detects the locking / unlocking of the windows, etc. In the illustrated example, one sensor 75 is described, but in this embodiment, the dwelling unit E2 is provided with multiple sensors 75, such as a sensor that detects the locking / unlocking of the front door of the dwelling unit E2 and a sensor that detects the locking / unlocking of the windows. The sensor 75 is provided with a locking / unlocking detection unit that detects the locking / unlocking of the key, a notification unit that notifies when the locking / unlocking detection unit detects the unlocking of the key while monitoring the locking / unlocking of the key, and a communication unit. When the communication unit of the sensor 75 detects the unlocking of the key while monitoring the locking / unlocking of the key, it notifies the intercom master unit 10 of the detection result by wireless communication.

[0028] The control room device 50 is configured to be able to communicate with each intercom master unit 10 via the control device 40 .

[0029] Each intercom master unit 10 can make calls to the lobby intercom 30 and the entrance sub unit 20, as well as to the management room unit 50 and other intercom master units 10 installed in other dwelling units E2, via the control device 40. Each intercom master unit 10 can also make calls to devices installed in spaces (e.g., kids' rooms) different from the dwelling unit E2 installed in the facility 5, via the control device 40. Furthermore, when other facilities are installed on the same site as the facility 5, in addition to the facility 5, each intercom master unit 10 can also make calls to intercom master units of other facilities via the control device 40. When a disaster prevention center is installed in the facility 5, each intercom master unit 10 can communicate with a device in the disaster prevention center via the control device 40. Here, the communication with the device in the disaster prevention center may be two-way communication, or may be one-way communication from the device in the disaster prevention center to each intercom master unit 10. In short, each intercom master unit 10 only needs to include a configuration for receiving at least information from the disaster prevention center by communicating with the device in the disaster prevention center. The disaster prevention center may be provided outside the facility 5.

[0030] Other intercom master units 10 in the facility 5, devices installed in the kids' room of the facility 5, intercom master units in other facilities, and devices in the disaster prevention center can also communicate with the intercom master unit 10, and correspond to communication terminals in the present disclosure.

[0031] In the following explanation, the entrance intercom unit 20, the lobby intercom 30, the management room device 50, other intercom master units 10 of the facility 5, devices installed in the kids' room etc. of the facility 5, intercom master units of other facilities, and the device in the disaster prevention center are collectively referred to as communication terminals.

[0032] (2) Composition Here, the configuration of the intercom master unit 10 serving as a display terminal will be described.

[0033] 1, the intercom master unit 10 includes a first communication unit 11, a second communication unit 12, a third communication unit 13, a fourth communication unit 14, a display unit 15, an operation unit 16, a call unit 17, a storage unit 18, and a control unit 19. Note that the intercom master unit 10 may be composed of multiple devices.

[0034] The intercom master unit 10 has, for example, a computer system having a processor and a memory. The processor executes a program stored in the memory, causing the computer system to function as the control unit 19. The program executed by the processor is pre-recorded in the memory of the computer system here, but may also be provided by being recorded on a recording medium such as a memory card, or may be provided via a telecommunications line such as the Internet.

[0035] The first communication unit 11 is a communication interface for communicating with the control device 40. The first communication unit 11 is connected to the lobby intercom 30 via the control device 40. For example, the first communication unit 11 receives an image transmitted from the lobby intercom 30. Furthermore, the first communication unit 11 is configured to be able to communicate bidirectionally with the lobby intercom 30 so that sound signals and control signals can be transmitted bidirectionally between the first communication unit 11 and the lobby intercom 30.

[0036] The second communication unit 12 is a communication interface for communicating with the front door slave unit 20. The second communication unit 12 is electrically connected to the front door slave unit 20 via a two-wire transmission path formed of, for example, a twisted pair wire or the like.

[0037] The third communication unit 13 is a communication interface for communicating with the sensor 70. The third communication unit 13 receives the detection result of the sensor 70 from the sensor 70 through wired communication. Note that communication with the sensor 70 may be wireless.

[0038] The fourth communication unit 14 is a communication interface for communicating with the sensor 75. The fourth communication unit 14 receives the detection result of the sensor 75 from the detector 70 by wireless communication using radio waves in the 920 MHz band, for example.

[0039] The display unit 15 displays images transmitted from the lobby intercom 30 and the entrance slave unit 20. In this embodiment, part of the operation unit 16 and the display unit 15 are realized by a touch panel. In other words, the display unit 15 displays buttons and the like that are part of the operation unit 16 in addition to images.

[0040] Operation unit 16 includes call-related buttons 150, unlock button 151, alarm sound-related buttons 152, fire confirmation button 153, emergency button 154, home button 155, and end button 156 (see FIG. 3). Furthermore, as described above, operation unit 16 includes buttons displayed on display unit 15. When a button displayed on display unit 15 is pressed, operation unit 16 accepts an instruction corresponding to the button.

[0041] The operation unit 16 accepts operations by a resident in the dwelling unit E2. When a predetermined operation (for example, a push operation) is performed on the call-related button 150 while the first communication unit 11 is receiving a control signal (call signal) for calling a resident from the lobby intercom 30, a call is made possible between the intercom master unit 10 and the lobby intercom 30. When a predetermined operation is performed again on the call-related button 150 while a call is possible, the call is ended. In other words, the communication between the intercom master unit 10 and the lobby intercom 30, which is the call source, is ended.

[0042] When the first communication unit 11 receives a call signal from the lobby interphone 30 or is able to communicate with the lobby interphone 30, and a predetermined operation (e.g., a push operation) is performed on the unlock button 151, an unlock signal is transmitted to the control device 40. At this time, the control device 40 unlocks the door.

[0043] Furthermore, when a predetermined operation (for example, a push operation) is performed on the call-related button 150 while the second communication unit 12 is receiving a control signal (call signal) for calling a resident from the front door slave unit 20, a call is made possible between the intercom master unit 10 and the front door slave unit 20. When a predetermined operation is performed again on the call-related button 150 while a call is possible, the call ends. In other words, the communication between the intercom master unit 10 and the front door slave unit 20 that is the call source ends.

[0044] The alarm sound-related button 152 is operated when the detection result of the detector 70 is a false alarm. When a resident performs a predetermined operation (for example, a push operation) on the emergency button 154, the alarm issued by the detector 70 is stopped.

[0045] The fire confirmation button 153 is operated when the detection result of the detector 70 is not a false alarm and a fire has occurred. When a resident performs a predetermined operation (for example, pressing) on ​​the emergency button 154, information that a fire has occurred is transmitted to the control room device. Furthermore, the intercom master unit 10 displays an alarm screen G11, which will be described later, on the display unit 15.

[0046] The emergency button 154 is operated by a resident of the dwelling unit E2 in the event of an emergency. For example, when a resident performs a predetermined operation (e.g., pressing) on ​​the emergency button 154, an emergency sound is issued from the microphone of the communication unit 17. When the predetermined operation is again performed on the emergency button 154, the notification of the emergency sound is stopped.

[0047] The home button 155 is operated when a basic screen G1 (see FIG. 4), which will be described later, is to be displayed on the display unit 15. The end button 156 is operated when the display of an image on the display unit 15 is to be ended.

[0048] The communication unit 17 includes a speaker and a microphone, and is configured to be able to communicate with the lobby interphone 30 and the entrance handset 20 .

[0049] The memory unit 18 is composed of a device selected from a ROM (Read Only Memory), a RAM (Random Access Memory), an EEPROM (Electrically Erasable Programmable Read Only Memory), etc. The memory unit 18 stores data of images captured by the lobby intercom 30 and data of collected audio. The memory unit 18 stores data of images captured by the entrance sub-unit 20 and data of collected audio. The memory unit 18 stores calls between the control room device 50, other intercom master units 10, a device installed in a kids' room in the facility 5, and intercom master units of other facilities. The memory unit 18 stores data related to the screen to be displayed by the display unit 15.

[0050] When the control unit 19 receives a control signal (call signal) and an image from the lobby interphone 30 via the first communication unit 11, it outputs sound data of the call sound to the speaker of the communication unit 17 and outputs the image to the display unit 15.

[0051] When the control unit 19 receives a control signal (call signal and image) from the entrance slave unit 20 via the second communication unit 12, it outputs sound data of a call tone to the speaker of the communication unit 17 and outputs the image to the display unit 15.

[0052] The control unit 19 transmits an unlock signal to the control device 40 via the first communication unit 11 when an operation to unlock the door provided in the common area E1 is performed.

[0053] When the control unit 19 receives communication from the lobby intercom 30, the front door subunit 20, the management room device 50, another intercom master unit 10, etc. while the answering mode is set for the control unit 19, the control unit 19 stores information acquired by the communication in the memory unit 18. For example, when a call signal is received from the lobby intercom 30 or the front door subunit 20, the control unit 19 stores image data captured at the sender of the call signal and audio data collected at the sender in the memory unit 18. If the lobby intercom 30 does not have an imaging device, only audio data is received from the lobby intercom 30 and stored in the memory unit 18. Similarly, if the front door subunit 20 does not have an imaging device, only audio data is received from the front door subunit 20 and stored in the memory unit 18.

[0054] When the control unit 19 receives a call signal from the control room device 50, another intercom master unit 10, or an intercom master unit of another facility, it stores in the memory unit 18 data of the voice collected at the source of the call signal.

[0055] Furthermore, if a delivery box is installed in facility 5, control unit 19 receives delivery information indicating that the package has been stored in the delivery box via control device 40. Control unit 19 stores the received delivery information in storage unit 18. The delivery information includes, for example, information indicating the location of the delivery box in which the package has been stored (for example, the number of the delivery box).

[0056] Furthermore, when the control unit 19 receives a notification from a device in the disaster prevention center via the control device 40 during the away mode, the control unit 19 stores the received notification in the storage unit 18 .

[0057] The control unit 19 periodically obtains weather information from the weather server, and stores the obtained weather information in the storage unit 18.

[0058] 1, the control unit 19 has a display control unit 101. The display control unit 101 creates a screen in response to an operation on the intercom master unit 10, and causes the created screen to be displayed on the display unit 15. The display control unit 101 controls the process related to the transition of the screen to be displayed on the display unit 15, and controls the display unit 15 so that the display unit 15 displays the screen to be displayed.

[0059] When a predetermined operation is performed on the emergency button 154, the control unit 19 transmits information to the control room device that a fire has broken out.

[0060] Furthermore, the display control unit 101 performs processing related to the playback of images (playback of moving images) and output of audio stored in the storage unit 18. Specifically, the display control unit 101 performs processing related to the playback of unplayed images among the images stored in the storage unit 18 and output of audio.

[0061] The intercom master unit 10 may have a communication unit that communicates with a server via a network such as the Internet.

[0062] (3) Screen Here, a description will be given of each screen that the intercom master unit 10 displays on the display unit 15. Note that the reference characters and dashed lines surrounding areas in Figures 4 to 48 are shown only for the purpose of explanation, and are not displayed on the actual screen.

[0063] (3-1) Basic screen (initial screen) First, the basic screen G1 will be described with reference to FIG.

[0064] The basic screen G1 is displayed on the display unit 15 when a predetermined operation is performed on the intercom master unit 10. For example, the basic screen G1 is displayed on the display unit 15 when the home button 155 (see FIG. 3) is pressed. In other words, when the home button 155 is pressed, the display control unit 101 generates the basic screen G1 and causes the display unit 15 to display the generated basic screen G1.

[0065] As shown in FIG. 4, the basic screen G1 includes a first display area R1, a second display area R2, a third display area R3, a fourth display area R4, a fifth display area R5, a sixth display area R6, a seventh display area R7, and an eighth display area R8.

[0066] In the first display area R1 (information display area), acquired information acquired through communication between the intercom master unit 10 and a communication terminal is displayed. Specifically, in the first display area R1, an image (captured image) P1 acquired through communication with any of the communication terminals of the entrance slave unit 20 and the lobby intercom 30 during the away mode is displayed as acquired information. In addition, in the first display area R1, an image representing acquired information (e.g., information indicating that a notification has been received) acquired through communication with any of the communication terminals such as the management room device 50, other intercom master units 10 of the facility 5, the device in the kids' room, and intercom master units of other facilities during the away mode is displayed. Note that the acquired information displayed as the image P1 is not limited to information acquired during the away mode. For example, when a resident of the dwelling unit E2 does not respond to a call even if he or she is at home, an image relating to information acquired through communication of the call may be displayed as the image P1.

[0067] In the first display region R1, in addition to the image P1, an image P2 for instructing playback and date and time information P3 indicating the date and time when the image P1 was captured are displayed.

[0068] When the intercom master unit 10 acquires multiple pieces of acquired information from one communication terminal in the away mode, and when the intercom master unit 10 acquires pieces of acquired information from each of two or more communication terminals, the most recent piece of acquired information is displayed in the first display area R1.

[0069] In the first display region R1, when information acquired through communication with at least one of the multiple communication terminals has not yet been played back, viewed, or listened to, an icon M10, which is unread information indicating that the information has not been played back (unread), is also displayed. For example, when there is a record of a visitor and there is no unplayed (unread) information, the icon M10 is not displayed, and the latest information among the played information is displayed as information P1 in the first display region R1. Also, when there is a record of a visitor and there is unplayed (unread) information, the icon M10 is displayed, and the latest information among the unplayed information is displayed as information P1 in the first display region R1. The icon M10 may be displayed flashing or lit.

[0070] In the second display area R2 (transition-related display area), transition-related information for transitioning from the basic screen G1 to a screen displaying an information group including the image P1 (acquired information) displayed in the first display area R1 and other acquired information (images) acquired from one or more communication terminals that have performed communication among the multiple communication terminals is displayed. In this embodiment, in the second display area R2, a square-shaped button B1, which is an icon for viewing or listening to information acquired by the intercom master unit 10 through communication with at least one of the multiple communication terminals, is displayed as transition-related information. A character string related to the content to be executed by the intercom master unit is displayed on the button B1 by performing a predetermined operation (for example, a pressing operation) on the button B1. In this embodiment, a character string (message) saying "View notification" is displayed on the button B1. This shows that the intercom master unit 10 operates so that the notification can be viewed by performing a predetermined operation on the button B1, that is, an operation to play information such as a moving image is performed.

[0071] In the second display area R2, when information acquired through communication with at least one of the multiple communication terminals has not yet been played back, viewed, or listened to, an icon M1 representing unplayed information indicating that the information has not yet been played back is also displayed. Note that, like the icon M10, the icon M1 may be displayed in a flashing manner or in a lit manner.

[0072] The third display area R3 (operation-related display area) displays a plurality of pieces of operation-related information (four in the illustrated example) with different display formats for operations related to at least one of the type of system to which the intercom master unit 10 is connected and the settings of the intercom master unit 10. Here, the display format includes at least one of the figure (shape) to be displayed, the symbol, character string, character shape, color, etc., written within the figure. In this embodiment, the symbols and names (characters) written on the buttons (icons) included in the third display area R3, which will be described later, are different.

[0073] In this embodiment, the call operation button B2, the imaging operation button B3, the display operation button B4, and the equipment operation button B5, which are square-shaped icons, are displayed in the third display area R3 as operation-related information with different display modes. The call operation button B2 displays contents related to the call operation. The imaging operation button B3 displays contents related to the imaging operation of the imaging device. The display operation button B4 displays contents related to the display of notifications from an external device. Here, the external device is, for example, a device provided in a system that monitors power usage, or a system that accumulates information to be notified to residents of the dwelling unit E2. The equipment operation button B5 displays contents related to the operation of equipment in the facility 5 (for example, a system related to elevator control) and equipment installed in the dwelling unit E2 (for example, a system related to crime prevention).

[0074] The call operation button B2 is operation-related information related to the setting operation of the intercom master unit 10. The image capture operation button B3 is operation-related information related to the setting of the type (connection destination) of the communication terminal (here, the entrance slave unit 20 and the lobby intercom 30) of the intercom system 2 to which the intercom master unit 10 is connected. The display operation button B4 and the equipment operation button B5 are operation-related information related to the setting of the type (connection destination) of the system to which the intercom master unit 10 is connected. For example, the display operation button B4 is operation-related information related to the setting of either a system that monitors power usage or a system that accumulates information to be notified to the resident of the dwelling unit E2 as the type of system to which the intercom master unit 10 is connected. Also, the equipment operation button B5 is operation-related information related to the setting of either a system related to elevator control or a system related to crime prevention as the type of system to which the intercom master unit 10 is connected.

[0075] The fourth display area R4 (operation switching display area) displays operation switching related information relating to an operation for switching the operation of at least one of the intercom master unit 10 and the system including the intercom master unit 10. In this embodiment, a first switching button B6 (icon) in a slide format for switching whether the intercom master unit 10 operates in an away mode and an operation content (here, "away") corresponding to the operation of the first switching button B6 are displayed in the fourth display area R4 as operation switching related information. The first switching button B6 may switch the operation of the security system as a system including the intercom master unit 10. For example, in this case, the operation mode of the intercom master unit 10 is set to the away mode by operating the first switching button B6, and the security system starts monitoring the dwelling unit E2.

[0076] In the fifth display area R5 (status display area), status-related information (e.g., a button-shaped icon) showing the status of the space (dwelling unit E2) in which the intercom master unit 10 is installed is displayed. In the fifth display area R5, as the status-related information, a slide-type second switching button B7 (icon) for switching the security monitoring operation for the dwelling unit E2 and an operation content corresponding to the operation of the second switching button B7 (here, "security") are displayed. Furthermore, the fifth display area R5 includes a status display area R10 that displays an icon showing the status of the security monitoring target as the status-related information. For example, in the status display area R10, an icon showing the monitoring target (e.g., a door icon) is displayed. The display control unit 101 changes the form of the displayed icon according to the monitoring status and the status of the monitoring target. For example, the display control unit 101 displays an icon showing the door open when the door is open (unlocked), and displays an icon showing the door closed when the door is closed (locked). Furthermore, the display control unit 101 changes the color of the icon when monitoring is in progress and the color of the icon when not monitoring is in progress. For example, the display control unit 101 displays the icon in blue when monitoring is in progress and in orange when not monitoring is in progress. Furthermore, if an abnormality is detected during monitoring (for example, if a door is detected to have been opened while the owner was away), an icon indicating that an alarm is being issued (here, a key-shaped icon) is displayed in addition to the door icon (see FIG. 4).

[0077] The sixth display area R6 (notification display area) displays notification-related information related to notifications to the user of the intercom master unit 10 (the resident of dwelling unit E2). In the sixth display area R6, a rectangular alarm notification button B8, which is an icon indicating that the detection result received from the detector 70 has been stored in the memory unit 18, is displayed as notification-related information. The alarm notification button B8 displays the content of the notification corresponding to the operation of the alarm notification button B8. Here, the alarm notification button B8 displays "alarm" as the notification content. Furthermore, if the notification content (detection result) as an alarm has not been displayed, an icon M2 indicating that it has not been displayed is also displayed.

[0078] In the sixth display area R6, a rectangular administrator notification button B9, which is an icon indicating that information acquired through communication with the management room device 50 (e.g., a notification from the administrator) is stored in the memory unit 18, is displayed as notification-related information. The administrator notification button B9 displays notification content corresponding to the operation of the administrator notification button B9. Here, the administrator notification button B9 displays "administrator message" as the notification content. Furthermore, if the notification content as the administrator message has not been displayed (or played), an icon M3 indicating that it has not been displayed (or played) is also displayed.

[0079] Furthermore, in the sixth display area R6, when a package is stored in the delivery box, a square-shaped delivery notification button B10, which is an icon indicating that a package has been stored, is displayed as notification-related information. The delivery notification button B10 displays notification content corresponding to the operation of the delivery notification button B10. Here, the delivery notification button B10 displays "Delivery" as the notification content. Furthermore, when the notification content as delivery is not yet displayed (or not yet played), an icon M4 indicating that it is not yet displayed (or not yet played) is also displayed.

[0080] Like the icon M10, the icons M2 to M4 may be displayed in a flashing manner or in a lit state.

[0081] The seventh display area R7 displays setting-related information related to settings for the intercom master unit 10.

[0082] In the eighth display region R8, the latest weather information obtained from a weather server, for example, the weather and the probability of precipitation, is displayed.

[0083] If the communication partner of the user's device is not equipped with an imaging device, image P5 indicating that only audio data is being played back is displayed as the acquired information instead of image P1 (see FIG. 5).

[0084] (3-2) Playback screen The playback screen G2 is displayed on the display unit 15 when a predetermined operation (for example, a pressing operation) is performed on the first display region R1 of the basic screen G1. In other words, when a predetermined operation is performed on the first display region R1, the display control unit 101 generates the playback screen G2 and causes the display unit 15 to display the generated playback screen G2.

[0085] As shown in FIG. 6, the playback screen G2 includes a playback area R21, a playback operation area R22, and a screen transition operation area R23.

[0086] In the playback area R21, the image P1 to be played back is displayed. For example, in the absence mode, a moving image P21 acquired through communication with either the communication terminal of the front door slave unit 20 or the lobby intercom 30 is displayed in the playback area R21. At this time, the sound of the moving image P21 is output from the speaker of the communication unit 17.

[0087] When the intercom master unit 10 acquires a plurality of pieces of information from one communication terminal in the away mode, and when the intercom master unit 10 acquires pieces of information from each of two or more communication terminals, the pieces of information are displayed (played) in order from the most recent information. When the playback target is only audio, an image similar to the image P5 shown in FIG. 5 is displayed in the playback area R21.

[0088] In the playback operation area R22, information related to operations related to playback is displayed. In this embodiment, the playback operation area R22 includes a volume button B21, a delete button B22, a cancel button B23, a skip forward button B24, a skip back button B25, a stop button B26, and a display switch button B27, which are rectangular icons.

[0089] The volume button B21 is operated when adjusting the volume of the sound output from the speaker of the communication unit 17 during playback. The delete button B22 is operated when deleting from the storage unit 18 the information to be played back.

[0090] The release button B23 is displayed when the image being displayed is in a protected state. The release button B23 is operated when the protection state of the image being displayed is to be released. For images that have not been played back, the initial state is an unprotected state (unprotected state). When an unprotected image is being displayed, a protection button is displayed instead of the release button B23. When a predetermined operation (for example, a pressing operation) is performed on the protection button, the control unit 19 puts the image being displayed in a protected state, and changes the button displayed from the protection button to the release button. Here, the protected state means that the image is protected and cannot be deleted. The unprotected state means that the protection applied to the image is released and the image can be deleted. When the image is in the protected state, the display control unit 101 may display an icon (for example, a key-shaped figure) or the like representing the protected state on the display unit 15 by superimposing it on the video image P21.

[0091] The forward button B24 is operated when there is a plurality of pieces of information to be played back and the playback order is to skip to the last piece of information. The back button B25 is operated when there is a plurality of pieces of information to be played back and the playback order is to skip (go back) to the first piece of information. The stop button B26 is operated when playing back. The display switch button B27 is operated when switching the display of each button displayed in the playback operation area R22 and the screen transition operation area R23. In FIG. 6, the display of each button is permitted (display ON state). In this state, when a predetermined operation (e.g., pressing operation) is performed on the display switch button B27, each button becomes hidden (display OFF state).

[0092] The screen transition operation area R23 displays information related to screen transition operations. In the screen transition operation area R23, a button B28, which is a square icon, is displayed. The button B28 is operated when transitioning to a screen (here, the basic screen G1) before transitioning to the playback screen G2.

[0093] (3-3) Timeline screen The timeline screen G3 is displayed on the display unit 15 when a predetermined operation (for example, a pressing operation) is performed on the button B1 in the second display area R2. In other words, when a predetermined operation is performed on the button B1 in the second display area R2, the display control unit 101 generates the timeline screen G3 and causes the display unit 15 to display the generated timeline screen G3.

[0094] As shown in FIG. 7, the timeline screen G3 includes a list display area R31, a tag display area R32, a first operation area R33, a second operation area R34, and a third operation area R35.

[0095] In the list display area R31, the acquired information P31 to P37 to be played back is displayed in thumbnail format in chronological order. In this embodiment, the date and the day of the week are displayed on the time axis, and the acquired information (captured images) to be played back in thumbnail format is displayed corresponding to the date. In the list display area R31, a plurality of times corresponding to the displayed plurality of acquired information (captured images) P31 to P37 are displayed. Here, the time is the time when the corresponding information was acquired. In the timeline image G3 shown in FIG. 7, the acquired information P31 to P37 are displayed separately above and below. Therefore, the list display area R31 can be made larger than when a plurality of acquired information is displayed in a straight line. This allows the acquired information P31 to P37 to be displayed in an easy-to-view manner.

[0096] Furthermore, in the list display region R31, an icon M31 indicating that the acquired information has not yet been played is also displayed for the acquired information that has not yet been played. In this embodiment, since the plurality of acquired information (captured images) P31 to P37 have not yet been played, the icon M31 is displayed for all of the acquired information (captured images) P31 to P37.

[0097] When a predetermined operation (e.g., a pressing operation) is performed on one of the acquired information P31 to P37 displayed in the list display area R31, the screen transitions to the playback screen G2, and the acquired information to be played is played. At this time, if the acquired information to be played is both image and audio, moving images and audio are played. If the acquired information to be played is only audio, audio is played. If the acquired information to be played is only images (text), only the images (text) are played (displayed).

[0098] In the tag display area R32, a plurality of tags B31 to B35 are displayed. Each of the plurality of tags B31 to B35 indicates a type of acquired information to be displayed in the list display area R31. When one of the plurality of tags B31 to B35 is selected, the acquired information corresponding to the selected tag is displayed in the list display area R31.

[0099] For example, when the tag B32 representing new arrival is selected, thumbnail images related to all acquired information that has not been played back and that has been acquired through communication originating from the communication terminal are displayed in the list display area R31. However, there are cases where the number of acquired information related to display exceeds a predetermined number and cannot be displayed on one screen. In this case, a scroll bar or a page switching button is displayed. When the tag B33 representing visitor is selected, only thumbnail images (e.g., acquired information P33, P34) related to acquired information acquired through communication originating from the entrance slave unit 20 and the lobby intercom 30, other intercom master units 10 of the facility 5, and other intercom master units of other facilities are displayed in the list display area R31. When the tag B34 representing management is selected, only thumbnail images (e.g., acquired information P31, P32) related to acquired information acquired through communication originating from the management room device 50 and the device of the disaster prevention center are displayed in the list display area R31. When the tag B35 representing the notice is selected, only thumbnail images relating to the acquired information acquired from the external device (for example, acquired information P35, P36, P37) are displayed in the list display area R31.

[0100] The first operation area R33 includes a button B36 which is a square icon operated when forcibly setting the acquired information P31-P37 displayed in the list display area R31 as played (read). In the second operation area R34, a button B37 which is a square icon operated when transitioning to a calendar format screen G4 described later is displayed. In the third operation area R35, a button B38 which is a square icon operated when transitioning to a screen before transitioning to the timeline screen G3 (here, the basic screen G1) is displayed.

[0101] When the tag B32 indicating new arrival is selected on the timeline screen, thumbnail images of all acquired information that has not yet been played back when communication has been performed with the intercom master unit 10 of another dwelling unit E2 and with intercom master units of other facilities using the intercom master unit 10 as the call source may be displayed in the list display area R31. Even in this case, the number of acquired information that has not yet been played back may exceed a predetermined number and may not be able to be displayed on one screen. In this case, a scroll bar, a page switching button, or the like is displayed.

[0102] (3-4) Calendar format screen The calendar-format screen G4 is displayed on the display unit 15 when a predetermined operation (e.g., a pressing operation) is performed on the button B37 in the second operation area R34 of the timeline screen G3. In other words, when a predetermined operation is performed on the button B37 in the second operation area R34 of the timeline screen G3, the display control unit 101 generates the calendar-format screen G4 and displays the generated calendar-format screen G4 on the display unit 15.

[0103] As shown in FIG. 8, the calendar-format screen G4 includes a calendar display area R41 and an operation area R42.

[0104] In the calendar display area R41, calendar-related information on the calendar for the month in which the operation was performed is displayed. At this time, for a day on which there is acquired information to be played back, a circular button B41 is displayed as an icon indicating that there is acquired information to be played back. In this embodiment, there is acquired information to be played back from February 15th to 18th. When a predetermined operation (for example, a pressing operation) is performed on the button B41, playback of the information to be played back (unplayed information) on the corresponding day is started. At this time, the screen transitions to the playback screen G2.

[0105] In the operation area R42, a button B42, which is a square icon that is operated when transitioning to a screen (here, the timeline screen G3) prior to transition to the calendar-format screen G4, is displayed.

[0106] By displaying the calendar, it is possible to easily grasp whether or not there is information available over a wide range of time periods.

[0107] Here, the button B42 is configured to be operated when transitioning to a screen (here, the timeline screen G3) before transitioning to the calendar format screen G4. In other words, when a predetermined operation (for example, a pressing operation) is performed on the button B42, transition to the timeline screen G3 occurs. However, this is not limited to the configuration. When a predetermined operation is performed on the button B42, transition to the basic screen G1 may occur.

[0108] (3-5) 1st call operation screen The first call operation screen G5 is displayed on the display unit 15 when a predetermined operation (e.g., a pressing operation) is performed on the call operation button B2 in the third display region R3 of the basic screen G1. In other words, when a predetermined operation is performed on the call operation button B2 in the third display region R3 of the basic screen G1, the display control unit 101 generates the first call operation screen G5 and displays the generated first call operation screen G5 on the display unit 15.

[0109] As shown in FIG. 9, the first call operation screen G5 includes a first call target display area R51 and an operation area R52.

[0110] In the first call target display region R51, one or more buttons (seven buttons B51 to B57 in this example) which are rectangular icons operated when specifying a call target are displayed. The one or more buttons operated when specifying a call target are displayed in one or more columns. In this embodiment, the buttons B51 to B57 are displayed in two columns. The buttons B51 to B57 display information (name) related to the call target and a figure identifying the call target.

[0111] In the operation region R52, a button B52, which is a square icon operated when transitioning to a screen (here, the basic screen G1) before transitioning to the first call operation screen G5, is displayed.

[0112] (3-6)Second call operation screen The second call operation screen G6 is displayed on the display unit 15 when a predetermined operation (for example, a pressing operation) is performed on any one of the one or more buttons B51 to B57 (icons) displayed in the first call target display area R51 of the first call operation screen G5. In other words, when a predetermined operation is performed on any one of the buttons B51 to B57 of the first call operation screen G5, the display control unit 101 generates the second call operation screen G6 and displays the generated second call operation screen G6 on the display unit 15. Here, a case where a predetermined operation is performed on the button B54 will be described.

[0113] As shown in FIG. 10, the second call operation screen G6 includes a second call target display area R61 and an operation area R62.

[0114] In the second call target display area R61, one or more square buttons (here, eight buttons B61 to B68) are displayed that correspond one-to-one to one or more dwelling units that have been registered in advance as call targets. The buttons B61 to B68 (icons) display information related to the call destination (the building and room number in which the dwelling unit is located). The one or more buttons displayed in the second call target display area R61 are displayed in one or more columns. In this embodiment, the buttons B51 to B57 are displayed in two columns.

[0115] In the operation region R62, a square button B62 is displayed which is operated when transitioning to a screen (here, the first call operation screen G5) before transitioning to the second call operation screen G6.

[0116] Here, the button B62 is configured to be operated when transitioning to a screen (here, the first call operation screen G5) before transitioning to the second call operation screen G6. In other words, when a predetermined operation (for example, a pressing operation) is performed on the button B62, the screen transitions to the first call operation screen G5. However, this is not limited to the above configuration. When a predetermined operation is performed on the button B62, the screen may transition to the basic screen G1.

[0117] Also, when there is one call destination corresponding to a button displayed in the first call target display area R51 of the first call operation screen G5, when a predetermined operation is performed on the button, the call destination corresponding to the button may be called without transitioning to the second call operation screen G6. For example, when the only call destination corresponding to the button B54 is "Room 101, Building A," the intercom master unit in Room 101, Building A may be called without transitioning to the second call operation screen G6 when a predetermined operation is performed on the button B54.

In other words, when a predetermined operation is performed on the imaging operation button B3 in the third display region R3 of the basic screen G1, the display control unit 101 generates the monitor selection screen G7 and causes the display unit 15 to display the generated monitor selection screen G7.

[0119] As shown in FIG. 11, the monitor selection screen G7 includes a monitor selection area R71 and an operation area R72.

[0120] In the monitor selection area R71, one or more buttons (two buttons B71 and B72 in this example) that are rectangular icons for selecting a location to be monitored are displayed in one direction. The buttons B71 and B72 display information (names) that indicate the locations to be monitored. For example, the name "first entrance" corresponds to the outer entrance of the dwelling unit E2. The name "second entrance" is an outer entrance of the dwelling unit E2 that is different from the outer entrance corresponding to the first entrance. In other words, when the dwelling unit E2 has multiple (for example, two) outer entrances, names are provided to correspond to the respective outer entrances. When a predetermined operation (for example, a push operation) is performed on the button B71, an image captured by the entrance slave unit 20 of the first entrance is displayed on the display unit 15. When a predetermined operation (for example, a push operation) is performed on the button B72, an image captured by the entrance slave unit 20 of the second entrance is displayed on the display unit 15.

[0121] If one or more buttons for selecting locations to be monitored cannot be displayed in a single row, they are displayed in multiple rows. Also, if cameras are installed in the lobby intercom 30, bicycle parking area, parking lot, etc., icons (buttons) for displaying images captured in these locations may be displayed.

[0122] In the operation region R72, a button B72, which is a square icon that is operated when transitioning to a screen prior to transition to the monitor selection screen G7 (here, the basic screen G1), is displayed.

[0123] (3-8) Content selection screen The content selection screen G8 is displayed on the display unit 15 when a predetermined operation (e.g., a pressing operation) is performed on the display operation button B4 in the third display region R3 of the basic screen G1. In other words, when a predetermined operation is performed on the display operation button B4 in the third display region R3 of the basic screen G1, the display control unit 101 generates the content selection screen G8 and causes the display unit 15 to display the generated content selection screen G8.

[0124] As shown in FIG. 12, the content selection screen G8 includes a content selection area R81 and an operation area R82.

[0125] In the content selection area R81, one or more buttons (two buttons B81, B82 in this example) which are rectangular icons for selecting the content to be displayed are displayed in one direction. The buttons B81, B82 display information (name) related to the content to be displayed. For example, the button B81 displayed as "information service" is operated when selecting information acquired from an external device (for example, local announcement information) as the content to be displayed. The button B82 displayed as "power usage" is operated when selecting the content to be displayed as the content to be displayed, when a home energy management system (HEMS) controller is installed in the dwelling unit E2 and the amount of power consumption in the dwelling unit E2 acquired by the controller is installed in the dwelling unit E2.

[0126] If one or more buttons for selecting the content to be displayed cannot be displayed in a single row, they are displayed in multiple rows.

In other words, when a predetermined operation is performed on the equipment operation button B5 in the third display area R3 of the basic screen G1, the display control unit 101 generates the operation selection screen G9 and displays the generated operation selection screen G9 on the display unit 15.

[0129] As shown in FIG. 13, the operation selection screen G9 includes an operation selection area R91 and an operation area R92.

[0130] In the operation selection area R91, one or more buttons (two buttons B91 and B92 in this example) that are rectangular icons for selecting a system (or device) to be operated are displayed in one direction. The buttons B91 and B92 display information (name) related to the system (or device) to be operated.

[0131] For example, the button B91 labeled "electric lock" is operated when locking or unlocking a component that is locked or unlocked by an electric lock (e.g., the front door of dwelling unit E2). In the operation selection area R91, an icon P91 indicating the state of the system (or device) corresponding to the button B91 is displayed below the button B91. In the illustrated example, it is shown that the electric lock is in an unlocked state. In this state, when a predetermined operation (e.g., a push operation) is performed on the button B91, the electric lock becomes in a locked state. In this case, the content indicated by the icon P91 is information indicating that the electric lock is locked.

[0132] Button B92 is operated when moving the elevator to the floor where dwelling unit E2 is located. When a predetermined operation (e.g., a push operation) is performed on button B92, intercom master unit 10 transmits a control instruction for the elevator to control device 40. Upon receiving the control instruction, control device 40 transmits a movement instruction to elevator control device 60 to move the elevator to the floor where dwelling unit E2 of intercom master unit 10 is located. Upon receiving the movement instruction, elevator control device 60 controls the elevator so that the elevator moves to the specified floor.

[0133] If one or more buttons for selecting a system (or device) to be operated cannot be displayed in a single row, they are displayed in multiple rows.

[0134] In the operation region R92, a button B93, which is a square icon that is operated when transitioning to a screen prior to transition to the operation selection screen G9 (here, the basic screen G1), is displayed.

[0135] (3-10) Security settings screen The crime prevention setting screen G10 is displayed on the display unit 15 by performing a predetermined operation (for example, a slide operation to the right) on the second switching button B7 in the fifth display area R5 of the basic screen G1. In other words, when a predetermined operation is performed on the second switching button B7 in the fifth display area R5 of the basic screen G1, the display control unit 101 generates the crime prevention setting screen G10 and causes the display unit 15 to display the generated crime prevention setting screen G10.

[0136] 14, the crime prevention setting screen G10 includes one or more setting display areas (four setting display areas R101 to R104 in this example), a first operation area R105, a second operation area R106, a third operation area R107, and a fourth operation area R108. The setting display areas R101 to R104 are provided on the crime prevention setting screen G10 along one direction.

[0137] In each of the setting display areas R101 to R104, crime prevention setting related information relating to the setting start and setting cancellation operations for the object (target circuit) of crime prevention setting is displayed. Here, in each of the setting display areas R101 to R104, crime prevention information P101 which is an icon and buttons B0101, B102, B103 are displayed as crime prevention setting related information.

[0138] The crime prevention information P101 includes a name and a figure representing the location for which crime prevention settings are to be made. The name of the location can be registered by the operator of the intercom master unit 10 (the resident of dwelling unit E2). If the name of the location has not been registered by the operator, "Crime Prevention" is displayed as the initial name. The figures included in the crime prevention information P101 can also be registered by the operator of the intercom master unit 10 (the resident of dwelling unit E2). For example, the operator can register a figure of a door and a figure of a window as the location for which settings are to be made. If the operator has not registered a figure representing a location, a figure representing a lock is displayed as the initial figure.

[0139] The button B101 includes the time until security monitoring starts. When a predetermined operation (for example, a pressing operation) is performed on the button B101, the time until security monitoring starts is counted down and displayed on the button B101. In FIG. 14, for example, the button B101 corresponding to the front door displays "300 seconds" as the time until monitoring of the front door starts (alert starts). When the operator of the intercom master unit 10 performs a predetermined operation on the button B101 corresponding to the front door, the time until security monitoring starts is counted down. The button B101 displays the remaining time until monitoring starts (the counted down time).

[0140] The button B102 is operated when security monitoring is to be started immediately for the corresponding set location, whereas the button B103 is operated when security monitoring is not to be performed.

[0141] In the first operation area R105, information for performing operations collectively on multiple locations to be monitored for crime prevention is displayed. In this embodiment, in the first operation area R105, an all release button B104 and an immediate alert button B105, which are icons, are displayed. The all release button B104 is operated when crime prevention monitoring is not to be performed on all monitoring targets displayed in the setting display areas R101 to R104. The immediate alert button B105 is operated when crime prevention monitoring is to be immediately started on all monitoring targets displayed in the setting display areas R101 to R104.

[0142] In the second operation area R106, switching information for switching the operation of at least one of the intercom master unit 10 and the system including the intercom master unit 10 is displayed. In this embodiment, a slide-type switching button B106 (icon) for switching whether the intercom master unit 10 operates in away mode is displayed in the second operation area R106 as switching information. The switching button B106 is a button having the same function as the first switching button B6 on the basic screen G1. By displaying the switching button B106 on the security setting screen G10, it is not necessary to transition to the basic screen G1 when setting away mode, and the number of setting operations can be reduced.

[0143] In the third operation area R107, control-related information regarding control of equipment installed in the facility 5 is displayed. In this embodiment, in the third operation area R107, a button B107, which is an icon, is displayed as the control-related information. The button B107 is operated when moving an elevator installed in the facility 5 to the floor where the dwelling unit E2 is located. The button B107 has the same function as the button B92 displayed on the operation selection screen G9. By displaying the button B107 on the security setting screen G10, it is not necessary to transition to the operation selection screen G9 when moving the elevator, and the number of operations can be reduced.

[0144] In the fourth operation area R108, a button B108, which is a square icon that is operated when transitioning to a screen prior to transition to the crime prevention setting screen G10 (here, the basic screen G1), is displayed.

[0145] (3-11) Alarm screen The alarm screen G11 is displayed on the display unit 15 when a predetermined operation (e.g., a pressing operation) is performed on the alarm notification button B8 in the sixth display region R6 of the basic screen G1. In other words, when a predetermined operation is performed on the alarm notification button B8 of the basic screen G1, the display control unit 101 generates the alarm screen G11 and causes the display unit 15 to display the generated alarm screen G11.

[0146] As shown in FIG. 15, the alarm screen G11 includes an alarm display area R111 and an operation area R112.

[0147] In the alarm display region R111, alarm information P111, which is an icon to be displayed as an alarm according to the detection result received from the sensor 70, is displayed. The alarm information P111 includes a graphic and a name representing the type of alarm. For example, when a fire should be notified (displayed) as an alarm, the alarm information P111 includes a graphic and a name representing the fire (see FIG. 15).

[0148] In the operation region R112, a button B112, which is a square icon that is operated when transitioning to a screen prior to transition to the alarm screen G11 (here, the basic screen G1), is displayed.

[0149] Depending on the detection of multiple sensors 70, it may be necessary to display multiple alarms. The alarm screen G11 shown in FIG. 15 is a screen for one alarm, and therefore cannot display multiple alarms all at once. Therefore, when multiple alarms exist, a multiple alarm screen G12 shown in FIG. 16 is displayed on the display unit 15. In other words, when multiple alarms are to be displayed, the display control unit 101 generates a multiple alarm screen G12 and causes the display unit 15 to display the generated multiple alarm screen G12.

[0150] As shown in FIG. 16, the multiple alarm screen G12 includes an alarm list display area R121 in addition to the above-mentioned alarm display area R111 and operation area R112.

[0151] In the alarm list display area R121, a list of information to be displayed as an alarm (information P121 to P124 in this case) is displayed in one direction. When one piece of information P121 to P124, which is an icon, is selected, the selected information is displayed in the alarm display area R111. Furthermore, when the alarm list display area R121 exists, that is, when there are five or more pieces of information to be displayed, at least one of a button B121 (icon) and a button B122 for instructing the display of undisplayed information is displayed in the alarm list display area R121. At this time, the image displayed in the alarm display area R111 is an image representing the type of alarm with the highest priority among the multiple alarms. When fire has the highest priority, alarm information P111 representing the type of alarm as fire is displayed in the alarm display area R111 as shown in FIG. 16.

[0152] When a predetermined operation (for example, a pressing operation) is performed on the buttons B121, B122, the display in the alarm list display area R121 switches from displaying the information P121 to P124 as icons to displaying information that is not displayed.

[0153] In this embodiment, the alarm screen G11 is described as being displayed on the display unit 15 by performing a predetermined operation (for example, a pressing operation) on the alarm notification button B8 in the sixth display region R6 of the basic screen G1. However, the alarm screen G11 (or the multiple alarm screen G12) may be forcibly displayed when the detector 70 detects an abnormality such as a fire.

[0154] (3-12) Message display screen The message display screen G13 is displayed on the display unit 15 when a predetermined operation (for example, a pressing operation) is performed on the administrator notification button B9 of the sixth display area R6 of the basic screen G1. In other words, when a predetermined operation is performed on the administrator notification button B9 of the basic screen G1, the display control unit 101 generates the message display screen G13 and displays the generated message display screen G13 on the display unit 15.

[0155] As shown in FIG. 17, the message display screen G13 includes a message display area R131 and an operation area R132.

[0156] In the message display area R131, acquired information acquired from a communication terminal that has communicated (e.g., the management room device 50) and identification information P131 (icon) including a graphic for identifying the communication terminal are displayed. In the present embodiment, the identification information P131 includes, as an example, acquired information acquired from the management room device 50 through communication with the management room device 50 (e.g., a message from the manager) and a graphic for identifying the management room device 50 (here, a human-shaped graphic representing the manager).

[0157] In the operation area R132, a call button B131, which is an icon operated when calling the communication terminal that sent the message, is displayed. For example, when a predetermined operation (e.g., a pressing operation) is performed on the call button B131 while the message shown in FIG. 17 is displayed on the message display screen G13, the control unit 19 of the intercom master unit 10 performs a calling operation on the management room device 50.

[0158] In addition, on the message display screen G13, a button to be operated when transitioning to a screen before transitioning to the message display screen G13 (here, the basic screen G1) may be displayed.

[0159] (3-13) Setting display screen The setting display screen G14 is displayed on the display unit 15 when a predetermined operation (e.g., a pressing operation) is performed on the button B11 in the seventh display region R7 of the basic screen G1. In other words, when a predetermined operation is performed on the button B11 in the seventh display region R7 of the basic screen G1, the display control unit 101 generates the setting display screen G14 and displays the generated setting display screen G14 on the display unit 15.

[0160] 18, the setting display screen G14 includes a setting type display area R141 and an operation area R142. The setting type display area R141 is disposed at the top of the setting display screen G14. The operation area R142 is disposed at the bottom left of the setting display screen G14.

Information indicating the type of setting contents (name related to the setting) and a figure indicating the type are displayed on the buttons B141 to B146.

[0162] 18, the button B141 displays "Sound" as a name related to settings. For example, when setting a ring tone, a predetermined operation (for example, a pressing operation) is performed on the button B141.

[0163] The button B142 displays "Calling Call" as a name related to settings. For example, when setting an answering message when there is a call in the answering mode, setting an inter-unit call, etc., a predetermined operation (for example, a pressing operation) is performed on the button B142.

[0164] In the button B143, "recording" is displayed as a name related to settings. For example, when making settings related to recording (settings of recording time, etc.), a predetermined operation (for example, a pressing operation) is performed on the button B143.

[0165] In the button B144, "screen" is displayed as a name related to settings. For example, when making settings related to the screen (settings such as screen resolution), a predetermined operation (for example, a pressing operation) is performed on the button B144.

[0166] In the button B145, "Security" is displayed as the name relating to the settings. For example, when making settings related to crime prevention, a predetermined operation (for example, a pressing operation) is performed on the button B145.

[0167] The button B146 displays "Initialize" as a name relating to settings. When returning the intercom master unit 10 to a state that was set at the time of shipment, a predetermined operation (for example, a push operation) is performed on the button B146.

[0168] If one or more buttons for selecting the type of setting content cannot be displayed in a single row, they are displayed in multiple rows.

[0169] In the operation region R142, a button B147, which is a square icon that is operated when transitioning to a screen (here, the basic screen G1) prior to transition to the setting display screen G14, is displayed.

[0170] The setting display screen G14 further includes a detailed information display area R143 disposed between the setting type display area R141 and the operation area R142, as shown in Fig. 19. The setting display screen G14 further includes an operation area R144 below the detailed information display area R143, as shown in Fig. 19.

[0171] In the detailed information display region R143, when a predetermined operation is performed on any of the buttons B141 to B146, an icon (for example, an icon in the form of a button) related to the setting corresponding to the button on which the predetermined operation was performed is displayed.

[0172] For example, when a predetermined operation is performed on the button B142, a plurality of square-shaped buttons (here, five buttons 1421 to 1425) for setting the call-related settings are displayed in the detailed information display area R143 (see FIG. 19). The buttons 1421 to 1425 display the type of setting in the upper row and the currently set contents in the lower row. For example, the button 1421 is a button operated when setting the incoming call time, and it is possible to recognize from the display content that the currently set incoming call time is 30 seconds. The button 1422 is a button operated when setting the unlocked call time, and it is possible to recognize from the display content that the currently set time is 10 seconds. The button 1423 is a button operated when setting an answering message, and it is possible to recognize from the display content that the currently set setting content is to output a fixed message immediately after a call. The button 1424 is a button operated when setting the answering message, and it is possible to recognize from the display content that the currently set answering message is enabled. Furthermore, button 1425 is a button that is operated when setting up a call between residences, and it can be recognized from the display content that the currently set content is a registered residence. Here, a registered residence indicates that calls can be made only to registered residences.

[0173] In the operation area R144, a button-type icon P141 that is operated when switching the display in the detailed information display area R143 is displayed. Here, the page switching icon P141 is displayed.

[0199] In the first operation area R192, a button B191 is displayed which is a square icon that is operated when deleting the registration of a dwelling unit for which inter-unit communication is permitted. When the operator of the intercom master unit 10 wants to delete the registration of a dwelling unit for which inter-unit communication is permitted, the operator performs a selection operation (e.g., a push operation) to select one of the icons displayed in the setting display area R191. Thereafter, when the operator performs a predetermined operation (e.g., a push operation) on the button B191, the control unit 19 of the intercom master unit 10 performs processing related to deleting the registration of the dwelling unit corresponding to the selected icon. At this time, the selected icon is not displayed on the call destination setting screen G19.

[0200] In the second operation area R193, a button B192, which is a square icon operated when transitioning to a screen (second dwelling unit selection screen G18) before transitioning to the call destination setting screen G19, is displayed. Note that, by operating the button B192, transition may be made to, for example, the basic screen G1 or the setting display screen G14.

[0201] (3-19) First confirmation screen The first confirmation screen G20 is displayed on the display unit 15 when the control unit 19 receives a detection result (for example, information indicating that a fire has been detected) from the detector 70. In other words, when the detector 70 detects a fire, the display control unit 101 generates the first confirmation screen G20 and causes the display unit 15 to display the generated first confirmation screen G20.

[0202] As shown in FIG. 25, the first confirmation screen G20 includes a confirmation display area R201 and an operation area R202.

[0203] In the confirmation display area R201, an icon P201 corresponding to the upper part of the intercom master unit 10 (the part including the alarm sound related button 152, the fire confirmation button 153, and the emergency button 154) is displayed.

[0205] Icon P204 displays a message regarding the operation of alarm sound related button 152. For example, icon P204 displays a message indicating that when the detection result from sensor 70 is a false alarm, the alarm issued by sensor 70 can be stopped by operating alarm sound related button 152. In this way, by displaying the content of the operation while displaying the icon corresponding to the actual button, it is possible to make it difficult to perform an erroneous operation.

[0206] Icon P205 displays a message regarding the operation of the fire confirmation button 153. For example, when the detection result from the detector 70 is not a false alarm and the operator (the resident of dwelling unit E2) confirms an abnormality (for example, a fire), a message to the effect that the operation should be performed is displayed on icon P205.

[0207] In the operation area R20, a button B201, which is a square icon that is operated when transitioning to a screen (for example, the basic screen G1) prior to transition to the first confirmation screen G20, is displayed.

[0208] When the first confirmation screen G20 is displayed on the display unit 15, if a predetermined operation is performed on the alarm sound related button 152, the screen displayed on the display unit 15 transitions from the first confirmation screen G20 to the basic screen G1.

[0209] When the first confirmation screen G20 is displayed on the display unit 15, if a predetermined operation is performed on the fire confirmation button 153, the screen displayed on the display unit 15 transitions from the first confirmation screen G20 to an alarm screen G11.

[0210] The first confirmation screen G20 may be displayed when a predetermined operation is performed on the alarm screen G11 or the multiple alarm screen G12. For example, when the control unit 19 receives a detection result (e.g., information indicating that a fire has been detected) from the sensor 70, the display control unit 101 may first display the alarm screen G11 or the multiple alarm screen G12. After the alarm screen G11 or the multiple alarm screen G12 is displayed, the first confirmation screen G20 is displayed by a predetermined operation.

[0211] Alternatively, the warning screen G11 or the multiple warning screen G12 and the first confirmation screen G20 may be displayed alternately.

[0212] (3-20) Second confirmation screen The second confirmation screen G21 is displayed on the display unit 15 when a predetermined operation is performed on the emergency button 154. In other words, when a predetermined operation is performed on the emergency button 154, the display control unit 101 generates the second confirmation screen G21 and causes the display unit 15 to display the generated second confirmation screen G21.

[0213] As shown in FIG. 26, the second confirmation screen G21 includes a confirmation display area R211 and an operation area R212.

[0214] In the confirmation display area R211, icons P211 corresponding to the upper part of the intercom master unit 10 (the part including the alarm sound related button B512, the fire confirmation button 153, and the emergency button 154) are displayed. The icons P211 include an icon P211 corresponding to the emergency button B514.

[0215] A balloon-shaped icon P213 is displayed in confirmation display region R211. Icon P213 corresponds to icon P212.

[0216] Icon P213 displays a message regarding the operation of emergency button 154. For example, after checking the status of dwelling unit E2, icon P213 displays a message indicating that the emergency sound can be stopped by operating emergency button 154. This makes it difficult to operate erroneously by displaying the content of the operation while displaying an icon corresponding to the actual button.

[0217] In the operation area R20, a button B211, which is a square icon that is operated when transitioning to a screen (for example, the basic screen G1) before transitioning to the second confirmation screen G21, is displayed.

[0218] When a predetermined operation is performed on the emergency button 154 while the second confirmation screen G21 is being displayed on the display unit 15, the screen displayed on the display unit 15 transitions from the second confirmation screen G21 to the basic screen G1.

[0219] (3-21) Call display screen The call display screen G22 is displayed on the display unit 15 when a call operation is performed on either the lobby intercom 30 or the front door unit 20. If any screen is displayed on the display unit 15 at the time of calling, the screen is forcibly changed to the call display screen G22. In other words, when a call operation is performed on either the lobby intercom 30 or the front door unit 20, the display control unit 101 generates the call display screen G22 and displays the generated call display screen G22 on the display unit 15.

[0220] As shown in FIG. 27, the call display screen G22 includes a plurality of images (in the illustrated example, a first image P221, a second image P222, and a third image P223) and buttons B221 to B227.

[0221] When the call display screen G22 is viewed in plan, the second image P222 and the third image P223 are arranged vertically to the right of the center on the call display screen G22 with equal sizes. The first image P221 is displayed in an area of ​​the call display screen G22 excluding the area where the second image P222 and the third image P223 are displayed. When three images are displayed on the call display screen G22, the first image P221 is displayed largest.

[0222] The first image P221 is an image (moving image) captured by the caller's imaging device during a call or a conversation. The second image P222 is an image (moving image) captured by a terminal other than the caller (e.g., an imaging device for security purposes installed in the common area E1). The third image P223 is an image (still image) captured by the caller's imaging device before the call (e.g., before the call operation is performed or while the call operation is being performed). The first image P221 and the second image P222 may be still images. The third image P223 may also be a moving image.

[0223] The button B221 is operated when recording an image captured by the imaging device of the calling party. When a predetermined operation (for example, a pressing operation) is performed on the button B221, the control unit 19 of the intercom master unit 10 starts recording the image.

[0224] The button B222 is operated when instructing the caller's imaging device to zoom. When a predetermined operation (for example, a pressing operation) is performed on the button B222, the intercom master unit 10 transmits an instruction related to zoom processing to the caller so that the caller's imaging device zooms. As a result, the caller zooms in on the imaging device.

[0225] The button B223 is operated when changing the display mode of the call display screen G22. Specifically, the button B223 is operated when switching between a multi-screen display mode in which the first image P221, the second image P222, and the third image P223 are displayed, and a single-screen (full screen) display mode in which the first image P221 is displayed on the entire screen. When a predetermined operation (for example, a pressing operation) is performed on the button B223, information indicating the changed display mode is displayed on the button B223. In FIG. 27, the display mode on the call display screen G22 is a multi-screen, and "full screen" is displayed on the button B223. When a predetermined operation (for example, a pressing operation) is performed on the button B223 in this state, the display mode is switched from the multi-screen display mode to the single-screen display mode. When the display mode is switched from the multi-screen to the single-screen (full screen), "multi-screen" is displayed on the button B223.

[0226] The button B224 is operated when a resident of the dwelling unit E2 does not want to answer a call even if the resident is at home. When a predetermined operation (for example, a pressing operation) is performed on the button B224, the screen transitions to an answering the call setting screen G23 described later.

[0227] The button B225 is operated when changing the image quality of the displayed image, the volume of the sound output from the speaker of the communication unit 17, and the like.

[0228] The button B226 is operated to switch the display of the buttons B221 to B227. In Fig. 27, the display of the buttons B221 to B227 is permitted (display ON state). In this state, when a predetermined operation (for example, a pressing operation) is performed on the button B226, the buttons B221 to B227 are switched to a non-display state (display OFF state).

[0229] The button B227 is operated to stop the ringing sound.

[0230] (3-22) Absence setting screen The answering-at-home setting screen G23 is displayed on the display unit 15 when a predetermined operation is performed on the button B224 of the call display screen G22. In other words, when a predetermined operation is performed on the button B224 of the call display screen G22, the display control unit 101 generates the answering-at-home setting screen G23 and displays the generated answering-at-home setting screen G23 on the display unit 15.

[0231] The answering machine setting screen G23 includes an image P231 and buttons B221 to B227, as shown in Fig. 28. The buttons B221 to B227 have already been described in the call display screen G22, so a description thereof will be omitted here.

[0232] The image P231 is an image (moving image) captured by the caller's imaging device during a call or conversation.

[0233] The answering-at-home setting screen G23 further includes a setting area R231. In the setting area R231, a plurality of (three in the illustrated example) radio buttons B231 to B233 are displayed. Furthermore, in the setting area R231, a plurality of messages M231 to M233 are displayed, which correspond to the plurality of radio buttons B231 to B233, respectively, and relate to sounds to be output to the caller when answering-at-home is set. For example, the message M231 indicates the content to be output to the caller when answering-at-home is set, when the radio button B231 corresponding to the message M231 is selected. Similarly, the message M232 indicates the content to be output to the caller when answering-at-home is set, when the radio button B232 corresponding to the message M232 is selected. The message M233 indicates that a message previously registered (recorded) by the user is output, when the radio button B233 corresponding to the message M233 is selected.

[0234] Furthermore, in the setting area R231, a button B234 is displayed. The button B234 is operated when one of the radio buttons B231 to B233 is selected and then output of the audio of a message corresponding to the selected radio button is to begin. For example, when a predetermined operation (e.g., a push operation) is performed on the button B234 after the radio button B231 is selected, the control unit 19 of the intercom master unit 10 transmits audio data of the message "I'm not available right now. If you need help, please beep..." to the caller. This causes the audio of the message to be output from the speaker of the caller.

[0235] The answering-do-not-attend setting screen G23 further includes a button B235. The button B235 is operated to switch between displaying and hiding the setting area R231. In the answering-do-not-attend setting screen G23 shown in Fig. 28, the setting area R231 is displayed. In this state, when a predetermined operation (for example, pressing) is performed on the button B235, the setting area R231 is hidden. When the setting area R231 is hidden, the answering-do-not-attend setting screen G23 becomes a screen equivalent to the call display screen G22.

[0236] (3-23) First image range setting screen The first video range setting screen G24 is displayed on the display unit 15 when a predetermined operation is performed by a worker of a construction company during the construction of the intercom master unit 10. In other words, when the worker performs the predetermined operation, the display control unit 101 generates the first video range setting screen G24 and displays the generated first video range setting screen G24 on the display unit 15. The first video range setting screen G24 is a screen used when setting the imaging range of the imaging device of the front door slave unit 20 that can communicate with the intercom master unit 10.

[0237] As shown in FIG. 29, the first video range setting screen G24 includes a setting display area R241 and an operation area R242.

[0238] The setting display area R241 includes a plurality of display areas. The number of display areas included in the setting display area R241 corresponds to the maximum number of front door slave units 20 to which the intercom master unit 10 can be connected. In this embodiment, it is assumed that the maximum number of front door slave units 20 to which the intercom master unit 10 can be connected is "2". In this case, the setting display area R241 includes two display areas R243 and R244.

[0239] In the display region R243, a name (here, "first intercom") P241 indicating the front door unit for which the video range can be set, and buttons B241 and B242 which are square icons are displayed.

[0240] The button B241 is operated when changing the image range of the imaging device of the front door slave unit 20 represented by the name P241. The button B241 displays the content representing the setting target (setting content) and the content representing the current setting state (status content). In this embodiment, the setting content is displayed at the top of the button B241, and the status content is displayed at the bottom.

[0241] The button B242 is operated to change the setting of the zoom position of the imaging device of the front door slave unit 20 represented by the name P241.

[0242] In display area R244, the names indicating the front door units for which the image range can be set are different from those in display area R243.

[0295] The second setting area R312 includes a third setting area R313, a fourth setting area R314, and an operation area R315.

[0296] In the third setting area R313, a plurality of icons P311, each including a radio button B316 for setting a ring tone, are displayed. Here, 12 icons P311 are displayed.

[0297] In the fourth setting area R314, a plurality of icons P312, each including a radio button B317 for setting the number of times the alarm will ring, are displayed. Here, two icons P312 are displayed.

[0298] A square icon, the Enter button B318, is displayed in the operation area R315. The Enter button B318 is operated to enter the selection of the caller for which the ringtone is to be set, the ringtone, and the number of rings.

[0299] The operator of the intercom master unit 10 first selects a call origin. Specifically, the operator selects one of the buttons B311 to B315 that corresponds to the call origin for which the ringtone is to be set. After the selection, the operator selects the ring tone and the number of rings. After all selections are made, the operator performs a predetermined operation on the decision button B318 to complete the settings. At this time, the control unit 19 stores the selected call origin in association with the selected ring tone and the number of rings. As a result, a call is made with the ring tone and the number of rings set for each call origin.

[0300] Each time a ringing sound is selected, the control unit 19 may output the corresponding ringing sound from the speaker of the communication unit 17. This allows the operator of the intercom master unit 10 to select a ringing sound while listening to (checking) the ringing sound.

[0301] In addition, on the ring tone setting screen G31, a button to be operated when transitioning to a screen before transitioning to the ring tone setting screen G31 (here, the setting display screen G14) may be displayed.

[0302] (3-31) Maintenance and correction screen Before describing the maintenance screen G32 shown in FIG. 39 and the correction screen G33 shown in FIG. 40, a description will be given of the screens (here, the setting display screen G14) before the transition of each of the maintenance screen G32 and the correction screen G33.

[0303] As described above, the setting display screen G14 includes the detailed information display area R143 disposed between the setting type display area R141 and the operation area R142.

[0304] When a predetermined operation is performed on the button B144 while the setting display screen G14 shown in FIG. 18 is being displayed, information such as icons relating to the screen settings is displayed in the detailed information display region R143.

[0305] When a predetermined operation is performed on button B144, multiple square icon buttons (four buttons 1441-1444 in this case) are displayed in detailed information display region R143 (see FIG. 38). Buttons 1441-1444 display at least a name representing the setting contents of the screen. In addition, contents representing the setting status may be displayed. For example, button 1441 displays the name of the setting contents of the screen and the setting status. In this case, the name is displayed in the upper row and the setting status is displayed in the lower row. Button 1443 displays only the name representing the setting contents of the screen.

[0306] Button 1441 is operated when setting the brightness of the screen. Button 1442 is operated when setting an initial screen that will be the home screen. Button 1443 is operated when performing maintenance on the screen. Button 1444 is operated when calibrating the touch panel.

[0307] Next, a description will be given of the maintenance screen G32 shown in Fig. 39. The maintenance screen G32 is displayed when performing maintenance (cleaning) of the screen.

[0308] 38 is displayed, a predetermined operation (for example, a pressing operation) is performed on the button 1443, and thus the maintenance screen G32 is displayed on the display unit 15. In other words, when a predetermined operation is performed on the button 1443 of the setting display screen G14, the display control unit 101 generates the maintenance screen G32 and causes the display unit 15 to display the generated maintenance screen G32.

[0309] On the maintenance screen G32, a message P321 is displayed to inform the user that the screen will be maintained.

[0310] The maintenance screen G32 includes an operation area R321. In the operation area R321, a button B321, which is a square-shaped icon that is operated when the display of the maintenance screen G32 is ended, that is, when maintenance is completed, is displayed. When a predetermined operation (for example, a pressing operation) is performed on the button B321, the screen displayed on the display unit 15 transitions from the maintenance screen G32 to, for example, the basic screen G1.

[0311] When the maintenance screen G32 is displayed, the control unit 19 disables operations on the touch panel. As a result, even if the operator of the intercom master unit 10 touches the display unit 15 while the maintenance screen G32 is displayed, there is no reaction. Therefore, the operator can easily perform maintenance.

[0312] Next, a description will be given of the correction screen G33 shown in Fig. 40. The correction screen G33 is displayed when adjusting the response position of the touch panel.

[0313] 38 is displayed, a predetermined operation (for example, a pressing operation) is performed on the button 1444, and the correction screen G33 is displayed on the display unit 15. In other words, when a predetermined operation is performed on the button 1444 of the setting display screen G14, the display control unit 101 generates the correction screen G33 and causes the display unit 15 to display the generated correction screen G33.

[0314] On the correction screen G33, a message P331 to the effect that correction will be performed and an icon P332 representing a cross-shaped graphic for designating a touch position are displayed.

[0315] The correction screen G33 includes an operation area R331. In the operation area R331, a button B331, which is a square icon that is operated when ending the display of the correction screen G33, that is, ending the correction, is displayed. When a predetermined operation (for example, a pressing operation) is performed on the button B331, the screen displayed on the display unit 15 transitions from the correction screen G33 to, for example, the basic screen G1.

[0316] When the correction screen G33 is displayed, the display control unit 101 displays a message P331 and an icon P332 on the display unit 15. The operator of the intercom master unit 10 touches the intersection (center) of the cross in the cross-shaped figure included in the icon P332. The control unit 19 corrects the response position based on the display position of the center and the position touched by the operator.

[0317] (3-32) Zoom screen As described above, the call display screen G22 displays the button B222 that is operated when issuing a zoom instruction to the calling imaging device.

[0318] The zoom screen G34 is displayed on the display unit 15 when a predetermined operation (for example, a pressing operation) is performed on the button B222. In other words, when a predetermined operation is performed on the button B222 of the call display screen G22, the display control unit 101 generates the zoom screen G34 and causes the display unit 15 to display the generated zoom screen G34.

[0319] The zoom screen G34 includes a first image P341, a second image P342, and buttons B221, B223 to B227, and B342, as shown in Fig. 41. The buttons B221, B223 to B227 have already been described in the call display screen G22, so description thereof will be omitted here.

[0320] The first image P341 is an image (moving image) captured by the caller's imaging device during a call or a conversation. The first image P341 is an image in which a partial area (e.g., an area including a person's face) of the first image P221 displayed on the call display screen G22 is enlarged, in other words, an image in which the person's face is zoomed in. The second image P342 is an image (still image) captured by the caller's imaging device before the call (e.g., before the call operation is performed or while the call operation is being performed). The first image P341 may be a still image. The second image P342 may also be a moving image.

[0321] The button B342 is operated when instructing the imaging device of the caller to perform wide-angle imaging with a wide imaging range. When a predetermined operation (for example, a pressing operation) is performed on the button B342, the intercom master unit 10 transmits an instruction related to wide-angle imaging processing to the caller so that the imaging device of the caller performs wide-angle imaging. As a result, the caller performs wide-angle imaging using the imaging device.

[0322] (3-33) Change screen As described above, on the call display screen G22, the button B225 to be operated when changing the image quality of the displayed image, the volume of the sound output from the speaker of the communication unit 17, and the like are displayed.

[0323] The change screen G35 is displayed on the display unit 15 by performing a predetermined operation (for example, a pressing operation) on the button B225. In other words, when a predetermined operation is performed on the button B225 of the call display screen G22, the display control unit 101 generates the change screen G35 and displays the generated change screen G35 on the display unit 15.

[0324] The change screen G35 includes an image P351 and buttons B221 to B227, as shown in Fig. 42. The buttons B221 to B227 have already been described in the call display screen G22, so a description thereof will be omitted here.

[0325] The image P351 is an image (moving image) captured by the caller's imaging device during a call or conversation.

[0326] The change screen G35 further includes a setting area R351. The setting area R351 includes a plurality of change operation areas (four change operation areas R352 to R355 in the illustrated example).

[0327] In the change operation area R352, a slide-type button B351 is displayed, which is an icon for switching between enabling and disabling the directional function of the microphone of the communication unit 17. The control unit 19 enables or disables the directional function of the microphone according to the setting of the button B351.

[0328] In the change operation area R353, a button B352, which is an icon for switching between enabling and disabling correction of the displayed image, is displayed. The currently set state is displayed in the button 352. In FIG. 42, the character "OFF" is displayed, indicating that image correction is disabled. The operator of the intercom master unit 10 switches between enabling and disabling image correction by performing a predetermined operation on the button B352. The control unit 19 enables or disables image correction according to the set content.

[0329] In the change operation area R354, a slider-type button B353, which is an icon for changing the screen brightness, and two buttons B354 and B355 are displayed. The button B354 is operated to make the screen darker. The button B355 is operated to make the screen brighter.

[0330] When the operator of the intercom master unit 10 changes the brightness of the screen, he or she slides the button B353 to change the brightness. Alternatively, the operator darkens the screen by performing a predetermined operation (e.g., a pressing operation) on the button B354, and brightens the screen by performing a predetermined operation (e.g., a pressing operation) on the button B354. The display control unit 101 controls the display unit 15 to display each screen at the set brightness.

[0331] In the change operation area R355, a slider-type button B356, which is an icon for changing the volume, and two buttons B357 and B358 are displayed. The button B357 is operated to decrease the volume. The button B358 is operated to increase the volume.

[0332] When changing the volume, the operator of the intercom master unit 10 slides the button B355 to change the volume. Alternatively, the operator performs a predetermined operation (e.g., a push operation) on the button B357 to turn down the volume, and a predetermined operation (e.g., a push operation) on the button B358 to turn up the volume. For example, the volume is increased by performing a pressing operation. The control unit 19 controls the volume of the sound to be output at the set volume. The audio section 17 is controlled to output the signal.

[0333] The change screen G35 further includes a button B359. The button B359 is operated to switch between displaying and hiding the setting area R351. In the change screen G35 shown in FIG. 42, the setting area R351 is in a displayed state. In this state, when a predetermined operation (for example, a pressing operation) is performed on the button B359, the setting area R351 is hidden. When the setting area R351 is hidden, the change screen G35 becomes a screen equivalent to the call display screen G22.

[0334] (3-34) Construction settings screen Similar to the display of the first video range setting screen G24, the installation setting screen G36 is displayed on the display unit 15 when a predetermined operation is performed by a worker of the installation company during installation of the intercom master unit 10. In other words, when the worker performs the predetermined operation, the display control unit 101 generates the installation setting screen G36 and causes the display unit 15 to display the generated installation setting screen G36.

[0335] As shown in FIG. 43, the construction setting screen G36 includes a menu display area G361 and an operation display area G362.

[0336] In the menu display area G361, a plurality of rectangular buttons (here, five selection buttons B361 to B365) which are icons for selecting the contents to be set during construction are displayed.

[0337] In this embodiment, the selection button B361 is operated when making settings related to calls and broadcasts (communications with the outside). The selection button B362 is operated when making settings related to notifications and report transfer. The selection button B363 is operated when selecting other systems (circuits) to connect to the device and making settings related to connections.

[0339] (3-35) First circuit setting screen The first circuit setting screen G37 is displayed on the display unit 15 by performing a predetermined operation (e.g., a pressing operation) on the selection button B363 while the construction setting screen G36 shown in Fig. 43 is displayed. In other words, when a predetermined operation is performed on the selection button B363 while the construction setting screen G36 shown in Fig. 43 is displayed, the display control unit 101 generates the first circuit setting screen G37 and displays the generated first circuit setting screen G37 on the display unit 15.

[0340] As shown in FIG. 44, the first circuit setting screen G37 includes a circuit selection area R371, a first operation area R372, and a second operation area R373.

[0341] In the circuit selection area R371, multiple circuit information P371 icons are displayed according to the number of circuits that can be connected to the device during construction. The circuit information P371 includes a name (circuit name) assigned to the circuit information P371, the contents (monitoring name) to be monitored in the circuit connected to the device (a circuit of another system or the device), and a rectangular change button B371 and a details button B372. The circuit names are circuit #1, circuit #2, circuit #3, ..., circuit #8. The monitoring names in the illustrated example are security #1, overcurrent, general-purpose alarm #1, external security #1, dead battery, water leak, switch strike, and connected device abnormality.

[0342] The change button B371 is operated when changing the connected circuit (circuit of another system or the own device), that is, when changing the monitoring target. The details button B372 is operated when making detailed settings regarding the monitoring target.

[0343] In the first operation area R372, a button-type icon P372 is displayed which is operated when switching the display in the circuit selection area R371. Here, the page switching icon P372 is displayed.

[0344] In the second operation region R373, a button B147, which is a square icon operated when transitioning to a screen before transitioning to the first circuit setting screen 37 (here, the construction setting screen G36), is displayed.

[0345] (3-36) Second circuit setting screen The second circuit setting screen G38 is displayed on the display unit 15 by performing a predetermined operation (for example, a pressing operation) on one of the multiple change buttons B371 while the first circuit setting screen G37 shown in Fig. 44 is displayed. In other words, when a predetermined operation is performed on one change button B371 while the first circuit setting screen G37 shown in Fig. 44 is displayed, the display control unit 101 generates the second circuit setting screen G38 related to the circuit information P371 corresponding to the change button B371 on which the predetermined operation has been performed, and causes the display unit 15 to display the generated second circuit setting screen G38.

[0346] As shown in FIG. 45, the second circuit setting screen G38 includes a setting selection area R381, a first operation area R382, and a second operation area R383.

[0347] In the setting selection area R381, a plurality of square-shaped icons P381 are displayed, which represent information related to connectable circuits (circuits of other systems or the own device). In each icon P381, a radio button B381 and information related to the connected circuit (circuits of other systems or the own device) (here, the monitor name) are displayed.

[0348] A square-shaped enter button B382 is displayed in the first operation area R382. The enter button B382 is operated to enter the selection of one of the multiple icons P381 displayed in the setting selection area R381.

[0349] In the second operation area R383, a button B383, which is a square icon operated when transitioning to a screen before transitioning to the second circuit setting screen G38 (here, the first circuit setting screen G37), is displayed.

[0350] When installing the intercom master unit 10, the worker selects from the multiple radio buttons B381 the radio button B381 that corresponds to the monitoring name to be included in the circuit information P371 selected on the first circuit setting screen G37. When the worker then performs a predetermined operation (for example, a press operation) on the decision button B382, the control unit 19 sets the circuit (the circuit of the other system or the own device) corresponding to the selected monitoring name as the communication partner. In short, the control unit 19 controls to transmit and receive information to and from the circuit (the circuit of the other system or the own device) corresponding to the selected monitoring name. Here, in the illustrated example, "unused" means that the corresponding circuit information P371 is not associated with a circuit to be connected.

[0351] (3-37) 3rd circuit setting screen The third circuit setting screen G39 is displayed on the display unit 15 by performing a predetermined operation (for example, a pressing operation) on one of the multiple detail buttons B372 when the first circuit setting screen G37 shown in Fig. 44 is displayed. In other words, when a predetermined operation is performed on one detail button B372 when the first circuit setting screen G37 shown in Fig. 44 is displayed, the display control unit 101 generates a third circuit setting screen G39 related to the circuit corresponding to the detail button B372 on which the predetermined operation has been performed, and causes the display unit 15 to display the generated third circuit setting screen G39.

[0352] As shown in FIG. 46, the third circuit setting screen G39 includes a first setting display area R391 and a second setting display area R392.

[0353] In the first setting display area R391, a plurality of square buttons are displayed, which are icons for making detailed settings related to monitoring via connection with a circuit (a circuit of another system or the own device) associated with the circuit information P371 selected on the first circuit setting screen G37. In the illustrated example, six buttons B391 to B396 are displayed in one direction in the first setting display area R391. Information indicating the contents of the detailed settings (names related to the detailed settings) and the current setting status are displayed on the buttons B391 to B396. In the illustrated example, the names related to the detailed settings are displayed in the upper row of each of the buttons B391 to B396, and the current setting status is displayed in the lower row.

[0354] 46, the button B391 displays "Display" as the name related to the detailed settings, and "Security #1" as the current setting status (currently set monitoring name). The button B391 is operated when setting or changing the monitoring name.

[0355] The button B392 displays "Control device report transfer" as the name of the detailed setting, and "Yes" as the current setting state. "Yes to control device report transfer" indicates that the detection results during security monitoring are to be transmitted to the control device 40. The button B392 is operated when setting or changing whether or not to transfer the report to the control device 40.

[0356] The button B393 displays "Doorphone Notification" as the name of the detailed setting, and "Yes" as the current setting state. "Notification to doorphone" indicates that the detection result during security monitoring is to be transmitted to the front door unit 20. The button B393 is operated when setting or changing whether or not to transmit a notification to the front door unit 20.

[0357] The button B394 displays "Security Alert Delay" as the name of the detailed setting, and displays "None" as the current setting. The button B394 is operated when setting or changing whether or not to delay the security alert.

[0358] The button B395 displays "Crime Prevention Pre-Alarm" as the name of the detailed setting, and "None" as the current setting state. The button B395 is operated when setting or changing the settings related to the crime prevention pre-alarm.

[0359] The button B396 has the name "Sensor detection method" for detailed settings, and the current setting The status is displayed as "b-contact." The button B396 is operated when setting or changing the detection method of the sensor used for crime prevention.

[0360] If one or more buttons for performing detailed settings cannot be displayed in a single row, they are displayed in multiple rows.

[0361] In the second settings display region R392, when a predetermined operation (for example, a pressing operation) is performed on any of the buttons B391 to B396, an icon related to the detailed settings corresponding to the button on which the predetermined operation was performed is displayed.

[0362] For example, when a predetermined operation is performed on the button B391, a plurality of square-shaped icons P391 (here, 12 icons P391) for making detailed settings related to the display are displayed in the second setting display area R392 (see FIG. 46). Each icon P391 includes a radio button B397 and a monitoring name. The worker selects a name corresponding to a connected circuit (a circuit of another system or the own device) from the plurality of icons P391, and performs a predetermined operation on the radio button B397 included in the selected icon P391. This selects the monitoring name to be displayed. The name included in the selected icon P391 corresponds to the name included in the crime prevention information P101 described in FIG. 14.

[0363] A confirm button B398 is further displayed in the second setting display region R392. The confirm button B398 is operated to confirm the selection of one icon P391 out of the multiple icons P391 displayed in the second setting display region R392.

[0364] In addition, in the third circuit setting screen G39, a button to be operated when transitioning to a screen before transitioning to the third circuit setting screen G39 (here, the second circuit setting screen G38) may be displayed. Alternatively, in the third circuit setting screen G39, a button-type icon to be operated when switching the display in the second setting display area R392 may be displayed.

[0365] (3-38) Incoming call end screen The incoming call end screen G40 is displayed on the display unit 15 when an operation other than an operation on the intercom master unit 10 (for example, an operation to end a call by a visitor) is performed during a call. In other words, when an operation to end a call is performed on something other than the intercom master unit 10 during a call, the display control unit 101 generates the incoming call end screen G40 and displays the generated incoming call end screen G40 on the display unit 15. Here, the operation on the intercom master unit 10 refers to an operation to end a call by pressing the call-related button 150 shown in FIG. 3, and an automatic call end operation by pressing the unlock button 151.

[0366] The incoming call end screen G40 includes a display area R401 and buttons B221 to B226, as shown in Fig. 47. The buttons B221 to B226 have already been described in the call display screen G22, so a description thereof will be omitted here.

[0367] In display region R401, a message P401 indicating that the call has ended is displayed.

[0368] In addition, the incoming call end screen G40 may be displayed on the display unit 15 when a call is made from either the entrance handset 20 or the lobby intercom 30 (when the call screen G22 is displayed) and an operation to end the call is performed by the caller, or when the intercom master unit does not respond to the call within a specified time.

[0369] Also, an incoming call end screen G40 may be displayed on the display unit 15 when a predetermined time has elapsed during a call.

[0370] During a call, for example, if an operation (process) related to terminating a call due to the calling side or time exceeding is performed even though the operator of the intercom master unit 10 (the person answering the call) is not performing any call operation himself, the person answering the call may become anxious that the intercom master unit 10 may have broken down. Therefore, by displaying the incoming call end screen G40, the operator of the intercom master unit 10 (the person answering the call) can know that the incoming call or call has ended due to something other than his / her operation. Therefore, the possibility of feeling anxious that the intercom master unit 10 may have broken down is reduced.

[0371] (3-39) Variations of the basic screen In the fifth display area R5 of the basic screen G1 described above, the second switching button B7 in a sliding format and an operation content (here, "crime prevention") corresponding to the operation of the second switching button B7 are displayed as the status related information. However, in the fifth display area R5, another button may be displayed instead of the second switching button B7 in a sliding format, as shown in FIG.

[0372] For example, a push button type button B411 may be displayed in the fifth display region R5 of the basic screen G1. The button B411 displays an icon representing the location of the dwelling unit E2 that is to be monitored for crime prevention (such as the front door or windows). When the button B411 is pressed, the basic screen G1 transitions to the crime prevention setting screen G10, and a countdown of the time until crime prevention monitoring begins for the monitoring target corresponding to the icon displayed on the button B411 begins. In this case, the button B411 is displayed in an inoperable state on the crime prevention setting screen G10.

[0373] (4) Advantages In this embodiment, acquired information (e.g., image P1) acquired through communication between the intercom master unit 10 and the communication terminal is displayed in the first display area R1 of the basic screen G1. Therefore, the operator of the intercom master unit 10 can know, for example, who visited the dwelling unit E2 while the operator was away, just by looking at the basic screen G1. In other words, the operator can know information acquired from other terminals, visitors, etc., without performing button operations on the basic screen G1.

[0374] In this embodiment, the timeline screen G3 displays information acquired from communication terminals such as the front door slave unit 20 and the lobby intercom 30, i.e., communication terminals that are the call sources of the intercom master unit. As a result, the timeline screen G3 displays information that the resident of the dwelling unit E2 of the intercom master unit 10 does not know, so that the resident can be informed of visitors while the resident is away, for example.

[0375] In addition, in the second operation area R106 of the security setting screen G10, a slide-type switching button B106 is displayed as switching information. Therefore, the operator of the intercom master unit 10 does not need to transition to the basic screen G1 again to operate the first switching button B6, so that the number of operations required for screen transition can be reduced.

[0376] Furthermore, in the third operation area R107 of the security setting screen G10, a button B107 is displayed as control-related information relating to the control of an elevator provided in the facility 5. Therefore, the operator of the intercom master unit 10 does not need to make a screen transition from the security setting screen G10 to the operation selection screen G9, and therefore the number of operations required for screen transition can be reduced.

[0377] (5) Variations The above embodiment is merely one of various embodiments of the present disclosure. The above embodiment can be modified in various ways depending on the design, etc., as long as the object of the present disclosure can be achieved. Modifications are listed below. The modifications described below can be applied in appropriate combination with the above embodiment.

[0378] In the above embodiment, the basic screen G1 is displayed as the initial screen, but the present invention is not limited to this configuration. The initial screen may be a screen (content screen) that displays information (for example, local announcement information) acquired from an external device. In this case, when the home button 155 displayed on the display unit 15 is pressed, the content screen is displayed on the display unit 15. Alternatively, the initial screen may be a screen customized according to the purpose of the facility 5 in which the intercom master unit 10 is installed.

[0379] The display mode of the icons such as the buttons described in the above embodiment may be changed by the installer or user of the intercom master unit 10. For example, the shape and color of the icon, the font and size of the characters when displaying the name, etc. may be changed.
