[0007] Hereinafter, a signal processing device and a lighting control system according to an embodiment will be described with reference to the drawings. Components having the same functions in the embodiments will be assigned the same reference numerals, and duplicated descriptions will be omitted. Note that the signal processing device and the lighting control system described in the following embodiment are merely examples and do not limit the embodiments.

[0008] A signal processing device (12) according to an embodiment described below includes a memory (20b) for storing setting information, a plurality of ports (21) assigned to input terminals or output terminals, and a control unit (20a) for performing arithmetic processing on input control signals based on the setting information stored in the memory (20b) and outputting the control signals. The control unit (20a) connects, with wires, display elements indicating input terminals to be set in the input setting and display elements indicating arithmetic processing to be set in the arithmetic processing, outputs display data of a setting operation screen in which, with wires, display elements indicating the arithmetic processing and display elements indicating output terminals to be set in the output setting, and stores, in the memory (20b), setting information based on information input to the setting terminal (14) that displays the setting operation screen. This realizes a signal processing device that can provide a setting operation screen that allows the correlation between input settings, arithmetic settings, and output settings to be visually recognized at a glance.

[0009] Furthermore, in the signal processing device (12) according to the embodiment, the setting operation screen has an input setting unit (40) that displays a display area (41) indicating an input terminal to be set in the input setting, an operation setting unit (60) that displays display areas (61, 62) indicating an arithmetic process to be set in the operation setting, and an output setting unit (80) that displays a display area (81) indicating an output terminal to be set in the output setting. This makes it possible to realize a signal processing device that can provide a setting operation screen that can clearly indicate, on a single screen, the input terminal to be set in the input setting, the arithmetic process to be set in the operation setting, and the output terminal to be set in the output setting.

[0010] Furthermore, in the signal processing device (12) according to the embodiment, the input setting unit (40) is displayed at one end of the setting operation screen, the output setting unit (80) is displayed at the other end of the setting operation screen, and the calculation setting unit (60) is displayed in an area on the setting operation screen between the input setting unit (40) and the output setting unit (80). This makes it possible to realize a signal processing device that can provide a setting operation screen that allows the flow of signals from the input terminal to the output terminal via the calculation setting to be visually recognized at a glance.

[0011] In addition, in the signal processing device (12) according to the embodiment, the connections are arrows indicating the flow of the control signals, thereby realizing a signal processing device that can provide a setting operation screen that allows the flow of control signals to be visually recognized at a glance.

[0012] Furthermore, in the signal processing device (12) according to the embodiment, the control unit (20a) displays a calculation setting block (61) showing the details of the calculation process as a display area showing the calculation process in the calculation setting unit (60). This makes it possible to provide a signal processing device that can display the details of the calculation process according to the calculation setting in a schematic manner and that can provide a setting operation screen that can visually display the details of the calculation process in an easily understandable manner.

[0013] Furthermore, in the signal processing device (12) according to the embodiment, when a plurality of arithmetic processes are performed, the control unit (20a) displays a plurality of arithmetic process setting blocks (61, 62) in the arithmetic process setting unit (60) and displays arrows indicating the flow of control signals between the arithmetic process setting blocks (61, 62). This makes it possible to provide a signal processing device that can provide a setting operation screen that can display the contents of the plurality of arithmetic processes in the arithmetic process setting in a schematic manner and that can visually clearly display the contents of the plurality of arithmetic processes and the flow of control signals between the arithmetic processes.

[0014] Furthermore, in the signal processing device (12) according to the embodiment, the control unit (20a) displays a scene setting block (71) that outputs a control signal based on scene data indicating a specific control signal to the calculation setting unit (60), and displays arrows indicating the flow of control signals between the scene setting block (71) and the calculation setting block (62). This makes it possible to provide a signal processing device that can provide a setting operation screen that can display in advance a schematic representation of calculation processing as calculation settings and scene data as a specific control signal, and that can visually clearly display the flow of control signals based on calculation processing and scene data.

[0015] Hereinafter, a lighting control system 1 having a DMX node 12 as a signal processing device (converter) according to an embodiment will be described. FIG. 1 is a diagram showing an example of the configuration of a lighting control system 1 having a DMX node 12 as a signal processing device according to an embodiment. 1 includes lighting fixtures 111, 112, ..., 11n, ..., a DMX node 12, and a dimmer console 13. In the lighting control system 1, the lighting fixtures 111, 112, ..., 11n, ... (hereinafter collectively referred to as "lighting fixtures 11") and the dimmer console 13 are connected to the DMX node 12. Furthermore, a setting terminal 14 is connected to the DMX node 12 in the lighting control system 1.

[0016] Lighting fixture 11 is a device to which a lighting control signal (control signal) is output from DMX node 12. Lighting fixture 11 has an interface for inputting a control signal, a light source, and a control unit for controlling the light emitted by the light source. Lighting fixture 11 controls the light (illumination) output by the lighting fixture as a whole by the control unit controlling the light emission state of each light source based on the lighting control signal input to the interface. Lighting fixture 11 controls the light it outputs using a lighting control signal that complies with the standards specified by each specification.

[0017] The lighting fixtures 11 connected to the DMX node 12 include lighting devices with dimming capabilities. The lighting fixtures 11 with dimming capabilities have light sources configured with semiconductor light-emitting elements such as LEDs (Light Emitting Diodes) that individually emit light of each color, such as red, blue, and green. In such lighting fixtures 11, a control unit controls the light sources of each color to control the color of light output.

[0018] Lighting fixtures 11, which provide lighting effects for studios, stages, and the like, perform dimming processes to change the illuminance, color, lighting range, and other aspects of the light they emit in accordance with an input lighting control signal. For example, lighting fixtures 11 are assigned a control address, such as a DMX address, in advance. When lighting fixtures 11 receive a lighting control signal containing a standard-compliant dimming signal from DMX node 12, they perform dimming processes in accordance with the dimming signal contained in the received lighting control signal if the control address contained in the received lighting control signal is the control address of the lighting fixture itself.

[0019] For example, when a lighting fixture 11 conforming to the DMX standard receives a DMX signal containing its own DMX address, it controls the intensity (dimming level) of light output by a light source such as a semiconductor light emitting element, the color or range of the light output, etc. in accordance with the dimming signal contained in the received DMX signal. Also, a lighting fixture conforming to RDM (Remote Device Management), which is an extension of the DMX standard, controls dimming in accordance with an RDM signal conforming to the RDM standard.

[0020] The DMX node 12 is connected to lighting fixtures 11, a dimmer console 13, and a setting terminal 14. For example, the DMX node 12 is connected to lighting fixtures 11 that output control signals (lighting control signals) based on standards such as the DMX standard or the RDM standard. The DMX node 12 is also connected to the dimmer console 13 or the setting terminal 14 via a network such as Ethernet (registered trademark) or a LAN (Local Area Network) in a state where bidirectional communication is possible. Note that in addition to the lighting fixtures 11, devices that are installed on stage equipment or the like and whose operation can be controlled by control signals may also be connected to the DMX node 12 as devices that output control signals.

[0021] The DMX node 12 has a communication control unit 20 and a plurality of ports 211, 212, ..., 21n (hereinafter collectively referred to as "ports 21"). The communication control unit 20 in the DMX node 12 has a control unit 20a and a memory 20b. The control unit 20a has a processor, a system memory, etc., and realizes various processing functions by the processor executing programs. For example, the control unit 20a has a function as an arithmetic processing unit that executes arithmetic processing, which will be described later, and a function as a setting processing unit that executes setting processing using a setting operation screen, which will be described later. The memory 20b includes a rewritable nonvolatile memory. The memory 20b stores scene data, which will be described later.

[0022] Each port 21 is an interface for inputting and outputting signals. Each port 21 has a connector that complies with a specific standard. For example, ports 211, 212, ..., 21n, ... include ports that have a connector that converts into a shape that allows connection of an Ethernet-standard communication line, and ports that have a connector that has a shape that allows connection of a DMX-standard communication cable.

[0023] Each port 21 is set as an input terminal or an output terminal by a setting process described later. Each lighting fixture 11 is connected to a port 21 that is set as an output terminal in the DMX node 12. For example, a DMX-compliant lighting fixture 11 is connected to a port 21 that has a DMX-compliant connector, and an ArtDMX-compliant lighting fixture 11 is connected to a port 21 that has an Ethernet-compliant connector.

[0024] The dimmer table 13 is connected to a port 21 that is set as an input terminal. For example, the dimmer table 13 is connected to a port 21 that has an Ethernet standard connector. The setting terminal 14 is connected to a port 21 that is capable of two-way communication. For example, the setting terminal 14 is connected to a port 21 that has an Ethernet standard connector. The dimmer table 13 and the setting terminal 14 may be connected to the port 21 via a repeater such as a hub. The lighting control system 1 may include multiple dimmer table 13. When there are multiple dimmer table 13, each dimmer table 13 may be connected to a port 21 that is set as an input terminal via a hub.

[0025] Moreover, the DMX node 12 has a setting function of providing a setting operation screen to be displayed on the setting terminal 14 and performing operation setting based on setting information input to the setting operation screen in the setting terminal 14. For example, when the setting terminal 14 is connected, the control unit 20a of the DMX node 12 outputs display data of the setting operation screen to be displayed on the setting terminal 14, and acquires information input to the setting operation screen in the setting terminal 14 to generate setting information.

[0026] As a specific example, the control unit 20a of the DMX node 12 provides a setting operation screen, which will be described later, as a Web page to the setting terminal 14. The control unit 20a of the DMX node 12 acquires various information input to the setting operation screen in the setting terminal 14 accessed by a Web browser, and generates setting information that associates input settings, calculation settings, and output settings based on the acquired information.

[0027] The dimmer console 13 is a device also known as an operation console or control console. For example, the dimmer console 13 has an operation unit such as a preset fader, a master fader, and buttons. The dimmer console 13 outputs operation instruction information for instructing dimming control of the lighting fixtures 11 based on instructions input by an operator using the operation unit. Specifically, the dimmer console 13 accepts operation instruction information including dimming instructions such as dimming level or color for the lighting fixtures 11 input by a user using the operation unit. The dimmer console 13 outputs a control signal to the DMX node 12, including a control address indicating the lighting fixture 11 to be controlled and the operation instruction information.

[0028] The dimmer console 13 is connected to the DMX node 12 via a network such as Ethernet. The dimmer console 13 may also be connected to the DMX node 12 or the setting terminal 14 via a hub. The communication connection between the DMX node 12 and the dimmer console 13 is not limited to a wired communication cable, and may be wireless. For example, the dimmer console 13 outputs a DMX signal indicating control details such as dimming level and color for a specific lighting fixture 11 to the DMX node 12.

[0029] The setting terminal 14 is a device into which setting information is input by an operator. The setting terminal 14 is an information processing device having a display unit, an operation unit, a processing unit, a communication unit, etc. The setting terminal 14 may be any information processing device that displays a setting operation screen provided by the DMX node 12 on the display unit and supplies information that the operator inputs on the operation unit to the setting operation screen displayed on the display unit to the DMX node 12. For example, the setting terminal 14 may be a personal computer (PC) such as a notebook type or a desktop type, or may be a mobile terminal such as a smartphone or a tablet terminal.

[0030] The setting terminal 14 is communicatively connected to the DMX node 12 by a communication unit. For example, the setting terminal 14 is communicatively connected to the DMX node 12 via a network such as Ethernet. The setting terminal 14 may also be connected to the DMX node 12 via a hub. The setting terminal 14 is not limited to being communicatively connected to the DMX node 12 by a wired communication cable, but may be communicatively connected to the DMX node 12 by wireless communication. A control unit of the setting terminal 14 communicatively connected to the DMX node 12 displays, for example, a web page including a setting operation screen provided by the DMX node 12 by a web browser on a display unit.

[0031] Next, the settings for the DMX node 12 as the signal processing device according to the embodiment will be described. The DMX node 12 is a device that processes a control signal (lighting control signal) for controlling lighting to be supplied to the lighting fixture 11 to be controlled. The DMX node 12 receives a lighting control signal from a dimmer console 13 or the like, processes the received lighting control signal, and outputs the processed lighting control signal to the lighting fixture 11.

[0032] To achieve such an operation, the DMX node 12 sets the processing contents from input to output of the control signal according to the lighting control setting information in which the input setting, calculation setting, and output setting are associated. For example, the DMX node 12 performs the input terminal setting as the input setting to set the port 21 as the input terminal for inputting the control signal from the dimmer console 13 or the like. Also, the DMX node 12 performs the calculation processing setting as the calculation setting to indicate the contents of the calculation processing for the input control signal. Also, the DMX node 12 performs the output terminal setting as the output setting to set the port 21 as the output terminal for outputting the calculated control signal.

[0033] The DMX node 12 provides a setting operation screen for setting input settings, calculation settings, and output settings in association with each other to the setting terminal 14. For example, the control unit 20a of the communication control unit 20 in the DMX node 12 provides the setting operation screen to the setting terminal 14 by a Web page, acquires information input to the setting operation screen in the setting terminal 14, and generates setting information based on the acquired information.

[0034] Hereinafter, a setting operation screen that the DMX node 12 serving as the signal processing device according to the embodiment displays on the setting terminal 14 in order to set (generate) setting information for signal processing will be described. FIG. 2 is a diagram showing an example of the configuration of a setting operation screen provided to the setting terminal 14 by the DMX node 12 as the signal processing device according to the embodiment. As shown in FIG. 2, the setting operation screen has an input setting section 40, a calculation setting section 60, and an output setting section 80.

[0035] On the setting operation screen, the input setting unit 40, the calculation setting unit 60, and the output setting unit 80 are arranged so that the flow of lighting control signals (control signals) from input to output can be easily seen. In the example shown in Fig. 2, the setting operation screen has the input setting unit 40 arranged at the top of the screen, the calculation setting unit 60 arranged at the center of the screen (between the input setting unit 40 and the output setting unit 80), and the output setting unit 80 arranged at the bottom of the screen.

[0036] The input setting unit 40 displays blocks (input setting blocks) 41, 42 that graphically display display areas showing the contents of settings related to input terminals (input terminal settings). The input setting unit 40 displays at least one input setting block 41, 42 selected by the user (operator). The input setting blocks 41, 42 displayed in the input setting unit 40 are connected to an operation setting block 61 displayed in the operation setting unit 60, which will be described later, by an arrow CS as a connection line. The arrow CS is a symbol indicating the flow of a control signal. In the display example shown in FIG. 2, it is indicated that the control signal input in the input setting blocks 41, 42 is output to the operation setting block 61.

[0037] Furthermore, it is also possible to set a plurality of control signals to be input as input settings, and a plurality of input setting blocks 41, 42 may be displayed in the input setting section 40 as shown in Fig. 2. That is, one or a plurality of input terminal settings can be specified in the input setting section 40 of the setting operation screen. When a plurality of input setting blocks 41, 42 are displayed, these input setting blocks 41, 42 are each displayed connected by an arrow CS to an operation setting block 61 of the operation setting section 60, which will be described later.

[0038] The operation setting section 60 displays blocks (operation setting blocks) 61, 62 that graphically display display areas showing the contents of settings related to operation processing for input signals (operation processing settings). At least one operation setting block 61, 62 is displayed in the operation setting section 60, and multiple operation setting blocks 61, 62 may be displayed.

[0039] Each calculation setting block receives at least one control signal. When multiple control signals are input, the calculation setting block outputs a control signal as a result of calculation processing of the multiple input control signals. The details of the calculation processing in each calculation setting block are set individually.

[0040] Each of the calculation setting blocks 61, 62 in the calculation setting unit 60 is displayed connected by arrows CS to the input setting blocks 41, 42, the other calculation setting blocks 61, 62, and the output setting block 81. In the display example shown in Fig. 2, the calculation setting block 61 is displayed connected to an arrow CS indicating that control signals are input from the input setting blocks 41 and 42 and an arrow CS indicating that a control signal from the calculation setting block 61 is output to the calculation setting block 62.

[0041] In addition to the input control signals, stored data (scene data) may be set as pre-set control signals in the calculation setting unit 60. The scene data indicating the pre-set control signals is stored in, for example, the memory 20b. In the display example shown in Fig. 2, the calculation setting unit 60 displays a block (scene setting block) 71 that graphically displays the scene data, which is the stored control signal.

[0042] For example, when a control signal as scene data is input to the calculation setting block 62, the scene setting block 71 is displayed in a connected state with an arrow CS pointing to the calculation setting block 62. In this case, the calculation setting block 62 is set to output a control signal to the output setting block 81, which is the result of calculation processing using the control signal input from the calculation setting block 61 and the control signal as scene data input from the scene setting block 71.

[0043] The output setting section 80 displays a block (output setting block) 81 that graphically displays a display area showing the contents of settings related to output terminals (output terminal settings). At least one output setting block 81 is displayed in the output setting section 80. The output setting block 81 in the output setting section 80 is displayed in a state where it is connected by an arrow CS from the operation setting block 62 in the operation setting section 60. In the display example shown in FIG. 2, the arrow CS indicates that a control signal from the operation setting block 62 is supplied to the output setting block 81. Note that, as for output settings, multiple output terminal settings may also be set in the output setting section 80.

[0044] Next, a description will be given of an example of setting signal processing using a setting operation screen provided by the DMX node 12 as the signal processing device according to the embodiment. FIG. 3 is a diagram showing an example of a display of a setting operation screen when performing settings for converting an input DMX signal into an Ethernet signal and outputting the Ethernet signal by the DMX node 12 as the signal processing device according to the embodiment. First, the setting terminal 14 connects to the DMX node 12, displays a setting operation screen provided by the DMX node 12 on the display unit, and accepts operation instructions from an operator using the operation unit. When the control signal input to the DMX node 12 is a DMX signal, the operator of the setting terminal 14 uses the operation unit to select and instruct the port 21 having a DMX standard connector as the input terminal in the input setting unit 40 of the setting operation screen.

[0045] When a port 21 (for example, port 213) having a DMX standard connector as an input terminal is selected and instructed, the DMX node 12 displays an input setting block 41 indicating the input terminal for the DMX signal in the input setting section 40, as shown in Fig. 3. When the DMX node 12 displays the input setting block 41, it displays an arrow CS connecting the input setting block 41 of the input setting section 40 and a calculation setting block 61 as a base unit displayed by default in the calculation setting section 60.

[0046] Furthermore, when the control signal output from the DMX node 12 is an Ethernet signal, the operator of the setting terminal 14 uses the operation unit to select and instruct the port 21 (for example, port 211) having an Ethernet standard connector as the output terminal in the output setting section 80 of the setting operation screen.

[0047] When the port 21 having an Ethernet standard connector is selected as the output terminal, the DMX node 12 displays an output setting block 81 indicating the output terminal of the Ethernet signal in the output setting section 80, as shown in Fig. 3. When the DMX node 12 displays the output setting block 81 in the output setting section 80, the calculation setting block 61 displayed in the calculation setting section 60 and the output setting block 81 of the output setting section 80 are connected by an arrow CS.

[0048] 3, the calculation process by the calculation setting block 61 converts the DMX signal input to the input terminal into an Ethernet signal and outputs it to the output terminal. However, the DMX node 12 may be configured to set the content of the calculation process to be executed by the calculation setting block 61 according to instructions from an operator at the setting terminal 14.

[0049] As described above, the setting operation screen shown in Fig. 3 can clearly show the input settings of the input terminal that inputs the DMX signal, the calculation settings that convert the DMX signal into an Ethernet signal, and the output settings of the output terminal that outputs the Ethernet signal, and can display the relationship between the input terminal settings, calculation processing settings, and output terminal settings so that they can be seen at a glance. As a result, the operator (user) can intuitively see not only the individual settings for input, calculation, and output, but also the flow of control signals according to the displayed settings.

[0050] FIG. 4 is a diagram showing an example of a display of a setting operation screen when performing settings for converting an input Ethernet signal into a DMX signal and outputting the DMX signal by the DMX node 12 as the signal processing device according to the embodiment. The setting terminal 14 displays a setting operation screen provided by the DMX node 12 on a display unit and accepts operation instructions from an operator using the operation unit. When the control signal input to the DMX node 12 is an Ethernet signal, the operator of the setting terminal 14 uses the operation unit to select and instruct the port 21 having an Ethernet standard connector as an input terminal in the input setting unit 40 of the setting operation screen.

[0051] When a port 21 (for example, port 211) having an Ethernet standard connector to be used as an input terminal is designated, the DMX node 12 displays an input setting block 41 indicating the input terminal of the Ethernet signal in the input setting section 40, as shown in Fig. 4. When the DMX node 12 displays the input setting block 41 indicating the input terminal, it displays the input setting block 41 of the input setting section 40 and the calculation setting block 61 of the base unit displayed in the calculation setting section 60, connected by an arrow CS.

[0052] Furthermore, when the control signal output from the DMX node 12 is a DMX signal, the operator of the setting terminal 14 uses the operation unit to select and instruct the port 21 (for example, port 213) having a connector of the DMX standard as the output terminal in the output setting section 80 of the setting operation screen. When the port 21 having a connector of the DMX standard is designated as the output terminal, the DMX node 12 displays an output setting block 81 indicating that the DMX signal is being output in the output setting section 80, as shown in Fig. 4. The DMX node 12 displays the calculation setting block 61 displayed in the calculation setting section 60 and the output setting block 81 displayed in the output setting section 80, connected by an arrow CS.

[0053] 4, the calculation setting block 61 is set to execute a calculation process of converting an Ethernet signal input to an input terminal into a DMX signal and outputting the DMX signal to an output terminal. However, the DMX node 12 may set the content of the calculation process executed by the calculation setting block 61 in accordance with an instruction from an operator at the setting terminal 14.

[0054] As described above, the setting operation screen shown in Fig. 4 can clearly show the input settings of the input terminal that inputs the Ethernet signal, the calculation settings that convert the Ethernet signal into a DMX signal, and the output settings of the output terminal that outputs the DMX signal, and can display the relationship between the input terminal settings, calculation processing settings, and output terminal settings so that they can be seen at a glance. As a result, the operator (user) can intuitively see not only the individual settings for input, calculation, and output, but also the flow of control signals according to the displayed settings.

[0055] FIG. 5 is a diagram showing a display example of a setting operation screen when setting arithmetic processing using stored data in the DMX node 12 as the signal processing device according to the embodiment. The setting terminal 14 displays a setting operation screen provided by the DMX node 12 on the display unit and accepts operation instructions from an operator using the operation unit. When the control signal to be input or output is a DMX signal, the operator of the setting terminal 14 selects and instructs the input setting unit 40 to select an input terminal for inputting the DMX signal and the output setting unit 80 to select an output terminal for outputting the DMX signal.

[0056] The DMX node 12 displays an input setting block 41 indicating an input terminal for inputting a DMX signal in an input setting section 40, and an output setting block 81 indicating an output terminal for outputting a DMX signal in an output setting section 80, according to a selection instruction by the operator. Furthermore, the DMX node 12 displays a calculation setting block 61 in a calculation setting section 60 of the setting operation screen, and also displays the input setting block 41 and the output setting block 81 connected by arrows CS in the calculation setting block 61.

[0057] Furthermore, when adding a control signal based on stored data (scene data) in the calculation process, the operator of the setting terminal 14 uses the operation unit to select and instruct the scene data to be added. When scene data is selected and instructed, the DMX node 12 displays a scene setting block 71 indicating the selected scene data in the calculation setting unit 60 of the setting operation screen. When the DMX node 12 displays the scene setting block 71 in the calculation setting unit 60, it displays an arrow CS connecting the scene setting block 71 and the calculation setting block 61, indicating that a control signal is supplied from the scene setting block 71 to the calculation setting block 61.

[0058] Furthermore, when adding scene data to the calculation process, the operator of the setting terminal 14 may also set the content of the calculation process in the calculation setting block 61. Two control signals are input to the calculation setting block 61: a control signal from the input setting block 41 and a control signal based on the scene data from the scene setting block 71. Therefore, the calculation setting block 61 is set as to how to perform calculation processing on the control signal from the input setting block 41 and the control signal based on the scene data from the scene setting block 71 and output the result to the output setting block 81.

[0059] For example, a backup scene function based on scene data can be set in the calculation setting block 61. The backup scene function is a function that outputs a lighting control signal based on scene data instead of the lighting control signal input to the DMX node 12 (reproduces a lighting control signal based on scene data). One example of the use of the backup scene function is to output a lighting control signal based on scene data when an abnormality occurs in the lighting control signal input to the DMX node 12, thereby preventing the abnormal lighting control signal from being output to a lighting fixture. Such a backup scene function can protect the lighting fixture connected to the output side and ensure the safety of the place where the light is irradiated.

[0060] The backup scene function applied to the calculation setting block 61 sets a switching condition for switching the lighting control signal output from the calculation setting block 61. For example, the switching setting may be set so that a lighting control signal based on scene data is output when a specific button on the dimmer console 13 is pressed. Alternatively, the switching setting may be set so that a lighting control signal based on scene data from the scene setting block is output when a specific signal value in the lighting control signal input from the input setting block 41 reaches a set value.

[0061] Next, a specific example of a setting operation screen provided by the DMX node 12 as the signal processing device according to the embodiment will be described. 6 to 9 are diagrams showing display examples of a setting operation screen provided by the DMX node 12 as a signal processing device according to the embodiment. The display examples shown in Figs. 6 to 9 show examples of transition of the display state of the setting operation screen. The setting operation screens shown in FIGS. 6 to 9 have an input setting section 40, a calculation setting section 60, and an output setting section 80, similar to the display example shown in FIG.

[0062] The setting operation screen has the input setting section 40 located at the top of the screen, the calculation setting section 60 located in the center of the screen (between the input setting section 40 and the output setting section 80), and the output setting section 80 located at the bottom of the screen. In addition to the input setting section 40, the calculation setting section 60, and the output setting section 80, the setting operation screens shown in Figures 6 to 9 also display an add module button I1, an add scene button I2, a back button I3, a clear button I4, and an apply button I5.

[0063] First, the input setting section 40 and the output setting section 80 in the setting operation screens shown in the display examples of FIGS. 6 to 9 will be described. 6 to 9, the input setting section 40 and the output setting section 80 each display the individual ports 21 of the DMX node 12. In the example shown in Fig. 6 to 9, the DMX node 12 has ten ports 21. In the input setting section 40 and the output setting section 80, ports E1, E2, P1, P2, ..., P8 that schematically display the ten ports 21 are displayed.

[0064] 6 to 9, ports E1 and E2 are terminals (ports) equipped with Ethernet standard connectors, and are displayed so that they are visually identifiable as Ethernet terminals by the connector shape, characters, etc. Ports P1, P2, ..., P8 are terminals (ports) equipped with DMX standard connectors, and are displayed so that they are visually identifiable as DMX terminals by the connector shape, characters, etc.

[0065] In the setting terminal 14 that displays the setting operation screen, the operator operates to specify a port to be used as an input terminal from the group of ports displayed in the input setting unit 40. The DMX node 12 displays the port specified as an input terminal in the input setting unit 40 as an input setting block. In addition, in the setting terminal 14 that displays the setting operation screen, the operator operates to specify a port to be used as an output terminal from the group of ports displayed in the output setting unit 80. The DMX node 12 displays the port set as an output terminal in the output setting unit 80 as an output setting block.

[0066] Next, the calculation setting section 60 in the setting operation screens of the display examples shown in FIGS. 6 to 9 will be described. 6 to 9, the calculation setting section 60 displays calculation setting blocks 61 and 62 indicating the details of the calculation process. For example, the calculation setting section 60 displays the calculation setting block 61 as the base unit, which is the initial setting, and when the add module button I1 is pressed, the calculation setting block 62 as an additional module is displayed. Furthermore, when the add scene button I2 is pressed, the calculation setting section 60 displays the specified scene setting block 71 to be added.

[0067] For example, the control unit 20a of the DMX node 12 displays a calculation setting block 61 as a base unit as shown in Fig. 6 on the calculation setting unit 60 in the initial display of the setting operation screen. The calculation setting block 61 shown in Fig. 6 displays an arrow CS indicating that a control signal is input from the input terminal and an arrow CS indicating that a control signal is output to the output terminal.

[0068] In the display examples shown in FIGS. 6 to 9 , the calculation setting block 61 displays a signal input section Cn at the top of the block, which can indicate that multiple signals are input. The signal input section Cn of the calculation setting block 61 consists of 16 connectors, each displaying a number in sequence. For example, when one control signal is input to the calculation setting block 61, an arrow indicating the control signal is connected to the connector in the signal input section Cn marked with a "1." When two control signals are input to the calculation setting block 61, an arrow CS indicating the first input signal is connected to the connector in the signal input section Cn marked with a "1," and an arrow CS indicating the second input signal is connected to the connector in the signal input section Cn marked with a "2." This allows the calculation setting block 61 to clearly indicate the input status of each control signal even when multiple control signals are input.

[0069] Next, the output setting or input setting in the output setting section 80 or input setting section 40 of the setting operation screens shown in the display examples of FIGS. 6 to 9 will be described. Furthermore, when any port in the output setting section 80 is selected by the setting terminal 14, the control section 20a of the DMX node 12 displays an output setting block with the selected port as an output terminal. For example, when the port P2 in the output setting section 80 is selected, the control section 20a of the DMX node 12 displays the display portion of the port P2 in the output setting section 80 as an output setting block 81, and connects the calculation setting block 61 of the calculation setting section 60 and the port P2 (output setting block 81) of the output setting section 80 with an arrow CS, as shown in FIG.

[0070] Furthermore, when any port in the input setting section 40 is selected by the setting terminal 14, the control section 20a of the DMX node 12 displays an input setting block with the selected port as an input terminal. For example, when port P1 is selected in the input setting section 40, the control section 20a of the DMX node 12 displays the display portion of port P1 in the input setting section 40 as an input setting block 41, and connects port P1 (input setting block 41) of the input setting section 40 and the calculation setting block 61 of the calculation setting section 60 with an arrow CS, as shown in FIG.

[0071] Next, detailed settings for a port (output terminal or input terminal) selected on the setting operation screen will be described. When any port is selected in the output setting section 80 or the input setting section 40 in the setting terminal 14, the control section 20a of the DMX node 12 displays a setting screen for receiving output setting or input setting for the selected port. For example, when an Ethernet standard port is selected as the output terminal or input terminal, the control section 20a of the DMX node 12 receives settings such as the communication standard and IP address. The control section 20a of the DMX node 12 stores the output setting or input setting for the output terminal or input terminal selected based on information specified by the operator of the setting terminal 14.

[0072] 7, when a port for which output setting is possible is selected in the output setting section 80 of the setting terminal 14, the control section 20a of the DMX node 12 displays a setting window W1 for setting the output for the selected port (output terminal). As a specific example, when the port E1 in the output setting section 80 is selected, the control section 20a of the DMX node 12 displays the setting window W1 associated with the port E1 (output setting block 81) to be the output terminal on the setting operation screen, as shown in FIG.

[0073] 7, it is possible to accept settings such as communication standard, IP address, universe, priority, merge, etc. for the Ethernet port that is to be used as the output terminal. The control unit 20a of the DMX node 12 stores the output setting for the output terminal selected based on the information specified in the setting window W1 by the operator of the setting terminal 14.

[0074] Next, the addition of a calculation process (module) in the calculation setting section 60 of the setting operation screen will be described. As shown in FIG. 8, a plurality of calculation setting blocks can be displayed in the calculation setting section 60 of the setting operation screen, and calculation setting blocks that become additional calculation elements can be added and displayed by instructing the module addition button I1.

[0075] 6 to 9, when a module addition button I1 is instructed, the control unit 20a of the DMX node 12 displays a calculation setting block 62 as a module to be added to the calculation setting unit 60. The calculation setting block 62 as an added module is capable of setting the contents of calculation processing. As a result, the setting operation screen can add a plurality of calculation setting blocks that become various calculation elements to the calculation setting unit 60 by instructing the addition of a module, and can display a plurality of calculation setting blocks as a graphic that can be seen at a glance.

[0076] For example, when an instruction to add a module is given in a state where a calculation setting block 61 is displayed in the calculation setting section 60, the control section 20a of the DMX node 12 displays a calculation setting block 62, which is a module to be added, between the calculation setting block 61 and the output setting block 81, as shown in Fig. 8. The DMX node 12 displays an arrow CS indicating that a control signal output from the calculation setting block 61 is input to the calculation setting block 62 as an added module, and also displays an arrow CS indicating that a control signal from the calculation setting block 62 is output to the output setting block 81. In this way, the calculation setting blocks, which are a plurality of calculation elements displayed in the calculation setting section 60, can be connected and displayed with arrows indicating the flow of control signals.

[0077] Next, the setting for adding scene data in the calculation setting section 60 on the setting operation screen will be described. 9, the calculation setting section 60 of the setting operation screen can display not only the calculation setting blocks 61 and 62 but also a scene setting block 71 that is added by an operator's instruction. The scene setting block 71 is a module that is added by an operator's instruction to press the scene addition button I2, and is a graphic block that indicates that a control signal based on pre-set scene data is output.

[0078] For example, when a scene addition button I2 is indicated on the setting operation screen shown in Fig. 8, the control unit 20a of the DMX node 12 additionally displays a scene setting block 71 of scene data designated by the operator on the calculation setting unit 60, as shown in Fig. 9. The scene data designated by the operator is stored data for outputting a specific control signal (a lighting control signal for reproducing a predetermined lighting state) that has been set in advance, and is saved in the memory 20b or the like.

[0079] On the setting terminal 14 that displays the setting operation screen, the operator specifies scene data to be added from the scene data stored in the memory 20 b. As a result, a scene setting block 71 is added and displayed in the calculation setting section 60 of the setting operation screen as a module that outputs a control signal based on the scene data specified by the operator.

[0080] 9, the scene setting block 71 is displayed above the calculation setting block 62 in the calculation setting section 60 on the setting operation screen, and displays an arrow CS indicating that the control signal to be output is input to the calculation setting block 62. In this case, a control signal (first control signal) output from the calculation setting block 61 and a control signal (second control signal) output from the scene setting block 71 are input to the calculation setting block 62. For the calculation setting block 62 to which these two control signals are input, calculation processing to be performed for the first control signal and the second control signal is set.

[0081] For example, a backup scene function based on the scene data as described above can be set in the calculation setting block 62. When setting the backup scene function, a switching condition for switching the output signal from the first control signal to the second control signal is set in the calculation setting block 62. As a result, the DMX node 12 set as shown in Fig. 9 can output a control signal (scene playback signal) from the scene setting block 71 added as scene data under a specific switching condition.

[0082] As described above, according to the DMX node as the signal processing device of the embodiment, it is possible to provide a setting operation screen that allows the contents of the input setting, the contents of the calculation setting, and the contents of the output setting to be visually confirmed at a glance, and further allows the user to grasp at a glance the series of steps, i.e., what calculation a control signal from which input terminal undergoes and what output terminal it is output from. As a result, the user can easily give setting operation instructions to the DMX node as the signal processing device of the embodiment while grasping the steps from when a control signal is input to when it is output, without having to set the input setting, calculation setting, and output setting individually.
