[0009] Hereinafter, an embodiment in which the present disclosure is embodied in an intercom system 1 will be described with reference to the drawings.

[0010] As shown in FIG. 1, the intercom system 1 is an intercom system for a detached house, and includes a doorway slave unit 2 through which a visitor P calls a resident, and a room master unit 3 which is called by the doorway slave unit 2.

[0011] As shown in Figure 2, the entrance unit 2 includes a call button 24 as an operation unit operated by a visitor P, a call unit 25 consisting of a speaker and a microphone, a camera 23 that captures images of the area around the entrance, and a CPU (Central Processing Unit) 21.

[0012] The room master unit 3 includes an operation unit 34 operated by the resident, a call unit 35 consisting of a speaker and a microphone, a monitor 33 that displays a GUI screen and the like, a CPU 31, and a memory unit 32. The display control unit 11 is stored in the memory unit 32 and functions as the display control unit 11 by being executed by the CPU 31. The operation unit 34 includes a home button 36 for displaying a home screen 112, icons of the GUI screen displayed on the touch panel monitor 33, and the like.

[0013] The storage unit 32 is composed of a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM is a non-volatile memory or the like, and stores various programs, files used by the programs, parameters, etc. The RAM temporarily stores data used when the various programs are executed.

[0014] 3, the display control unit 11 includes a plurality of GUI components that respectively generate a plurality of GUI screens, and a screen adjustment component 111 that adjusts the generated GUI screens. The plurality of GUI components cooperate with each other via the screen adjustment component 111 and function as the GUI application 12. The screen adjustment component 111 can employ a compositing window manager.

[0015] The GUI screen includes service screens that correspond to the plurality of functions included in the intercom system 1, and a home screen 112 that allows the resident to select one function from the plurality of functions (see FIG. 5).

[0016] The service screens include, for example, a call screen 113, a video playback screen 114 for playing recorded videos, and a settings screen 115 (see FIG. 5). The call screen 113 is used, for example, when a resident makes a call in response to a call from a visitor P. The video playback screen 114 is used for playing back video captured by the camera 23. The settings screen 115 is used for setting the environment of the intercom system 1. The environment settings include settings for the receiver volume and playback volume of the room master unit 3. The video captured by the camera 23 includes, for example, past video stored in the memory unit 32 of the room master unit 3 and current video captured of the surroundings of the front door slave unit 2.

[0017] The GUI components include a service component that generates a service screen and a home component 121 that generates a home screen 112. The service components include, for example, a call component 122 that generates a call screen 113, a video playback component 123 that generates a video playback screen 114, and a setting component 124 that generates a setting screen 115.

[0018] The screen adjustment component 111 displays only one of the multiple GUI screens and hides the other GUI screens. Specifically, for example, a GUI component in a displayed state notifies the screen adjustment component 111 of icon identification information of the tapped icon, and the screen adjustment component 111 can be configured to display the GUI screen in a hidden state and hide the GUI screen in a displayed state based on the icon identification information.

[0019] It is also possible to provide the screen adjustment component 111 with a digital zoom function that enlarges the video screen 116 and displays it on the monitor 33. In this case, the screen adjustment component 111 includes a display mode switching unit 111a that switches the display mode, a video screen enlargement unit 111b that enlarges the video screen 116 by a predetermined magnification, and a display area setting unit 111c that sets the display area R.

[0020] The display modes include a normal display mode in which the moving image screen 116 is displayed at the same magnification, and an enlarged display mode in which the moving image screen 116 is enlarged at a predetermined magnification by software processing.

[0021] The display mode switching unit 111a is configured to switch the display mode when the user taps an icon (not shown) for switching the display mode, for example. Alternatively, the display mode switching unit 111a may be configured to switch the display mode when triggered by a double tap operation or the like by the user.

[0022] 4(a), when the display mode is the normal display mode, the moving image screen enlargement unit 111b maintains the moving image screen 116 at the same magnification. The display area setting unit 111c sets a display area R with a center Rc set at the center position of the moving image screen 116. The display area R of the moving image screen 116 is displayed on the monitor 33. The shaded area indicates the area displayed on the monitor 33 when the display mode is the normal display mode.

[0023] 4(b), when the display mode is the enlarged display mode, the moving image screen enlargement unit 111b enlarges the moving image screen 116 by a predetermined magnification. The display area setting unit 111c sets a display area R with a center Rc at the center position of the moving image screen 116. The display area R of the moving image screen 116 is displayed on the monitor 33.

[0024] Here, when the user taps on the monitor 33, the display area setting unit 111c sets a display area R' with the tapped position as its center Rc'. The video screen 116 displayed on the monitor 33 moves from the display area R to R'.

[0025] The display control unit 11 includes a video processing unit 13 that receives video information from the camera 23. The video processing unit 13 includes a video component 131 that generates a video screen 116 based on the video information. A video component 131 is provided for each camera 23. If the intercom system 1 includes multiple cameras 23, multiple video components 131 are provided corresponding to the respective cameras 23. This makes it possible to simultaneously receive video information from multiple cameras 23 and simultaneously generate multiple video screens 116.

[0026] 5, the screen adjustment component 111 arranges the video screen 116 below the video playback screen 114. The video playback screen 114 includes a transparent area 114a that allows the video screen 116 to be transparent. The screen adjustment component 111 arranges the video screen 116 so as to overlap with the transparent area 114a of the video playback screen 114.

[0027] Next, the operation of the intercom system 1 configured as above will be described with reference to FIGS.

[0028] As shown in FIG. 6, the GUI screen displayed on the monitor 33 of the intercom system 1 changes by tapping an icon.

[0029] In the initial state, the home screen 112 is in a displayed state, and the service screen is in a hidden state. For example, when a resident taps the call icon 112a on the home screen 112, the call screen 113 is in a displayed state, and the home screen 112 is in a hidden state. When a resident taps the call end icon 113a on the call screen 113, the call screen 113 is in a hidden state, and the home screen 112 is in a displayed state.

[0030] 7, for example, when the home screen 112 is displayed on the monitor 33, if the resident taps the call icon 112a on the home screen 112, icon identification information of the call icon 112a is notified to the screen adjustment component 111, and the screen adjustment component 111 puts the home screen 112 in a hidden state and the call screen 113 in a displayed state. Thereafter, when the resident taps the call end icon 113a on the call screen 113, icon identification information of the call end icon 113a is notified to the screen adjustment component 111, and the screen adjustment component 111 puts the call screen 113 in a hidden state and the home screen 112 in a displayed state.

[0031] According to the intercom system 1 configured as described above, the multiple GUI screens displayed on the monitor 33 are each generated using independent GUI components. Therefore, if an error occurs in one GUI screen or a change needs to be made, only the GUI component that generates that GUI screen needs to be investigated or changed, which improves the efficiency of maintenance work. For example, when adding a new GUI screen or changing an existing GUI screen, the effect does not extend to the entire GUI application 12, thereby reducing the effort and cost of the work.

[0032] Furthermore, if an error occurs on the GUI screen, it is possible to avoid restarting the entire intercom system 1, thereby not impairing the UX (user experience). For example, if an error occurs while displaying one of the service screens (113, 114, 115), the home screen 112 can be displayed and the corresponding service component (122, 123, 124) can be restarted in the background.

[0033] Furthermore, it is possible to operate GUI screens in parallel to avoid complicated control. For example, if a call with front door slave unit 2 starts while video playback screen 114 is being displayed, video playback screen 114 can be paused, call screen 113 can be displayed in front of video playback screen 114, and after the call ends, the paused video playback screen 114 can be resumed as is.

[0034] In addition, by using the GUI components in other intercom systems 1, development efforts and costs can be reduced.

[0035] The present disclosure is not limited to the above-described embodiment, and the configuration of each part can be arbitrarily changed and implemented within the scope of the spirit of the invention.

[0036] For example, the present disclosure can be configured as an intercom system 1 for an apartment building, which can be configured with a front door slave unit 2 provided in each unit of the apartment building, a room master unit 3, a lobby intercom (not shown) provided at the entrance to the building, and a controller (not shown) that controls the intercom system 1. In this case, the display control unit 11 can be disposed in, for example, the room master unit 3, the lobby intercom, the controller, etc. [Explanation of symbols]
