[0010] The following describes in detail, with reference to the drawings, the configurations for implementing the processing by the lighting control device according to the present application (hereinafter referred to as "embodiments"). Note that these embodiments do not limit the lighting control device according to the present application. Furthermore, the same parts are denoted by the same reference numerals in each of the following embodiments, and redundant descriptions are omitted.

[0011] The lighting control device 10 described below includes a collection unit 151 and a setting unit 152. The collection unit 151 collects lighting information from lighting fixtures that can communicate with the lighting control device 10. The setting unit 152 sets a universe and an address associated with that universe for each lighting fixture and the node to which the lighting fixture is connected, based on the lighting information collected by the collection unit 151 and predetermined rules.

[0012] Furthermore, the setting unit 152 according to the embodiment described below sets a universe for a node and sets sequential addresses associated with that universe for lighting fixtures.

[0013] Furthermore, the setting unit 152 according to the embodiment described below sets a first universe for each node and sets sequential addresses associated with the first universe for each lighting fixture. When the number of addresses associated with the set first universe reaches the upper limit, it sets a second universe for each node to which the remaining lighting fixtures are connected and sets sequential addresses associated with the second universe for each of the remaining lighting fixtures.

[0014] Furthermore, the setting unit 152 according to the embodiment described below sets a universe and an address associated with that universe, depending on the node to which the lighting fixture is connected.

[0015] Furthermore, the setting unit 152 according to the embodiment described below sets a universe and an address associated with that universe, depending on the port of the node to which the lighting fixture is connected.

[0016] In addition, the setting unit 152 according to the embodiment described below sets a universe and an address associated with the universe according to the position of the node to which the lighting fixture is connected.

[0017] In addition, the collection unit 151 according to the embodiment described below further collects new lighting information regarding a new lighting fixture that has newly become communicable with the lighting control device 10. Then, when the new lighting information is collected, the setting unit 152 sets a universe and an address associated with the universe for each of the new lighting fixture and the node to which the new lighting fixture is connected, based on the new lighting information and a predetermined rule.

[0018] In addition, the setting unit 152 according to the embodiment described below sets a universe different from the lighting fixture and an address associated with the universe for each of the new lighting fixture and the node to which the new lighting fixture is connected.

[0019] In addition, the setting unit 152 according to the embodiment described below re-sets a universe and an address associated with the universe for each of the lighting fixture and the node to which the lighting fixture is connected, based on the lighting information, the new lighting information, and a predetermined rule, and sets a universe and an address associated with the universe for each of the new lighting fixture and the node to which the new lighting fixture is connected.

[0020] The lighting control device 10 described below further includes a management unit 153. The management unit 153 manages by associating the universe set for each of the lighting fixture and the node to which the lighting fixture is connected and the address associated with the universe with a predetermined scene.

[0021] (An example of a lighting control system) An example of a lighting control system will be described with reference to FIG. 1. FIG. 1 is a diagram showing an example of an information processing system according to an embodiment. The lighting control system 1 shown in FIG. 1 is, for example, a system that supports the preparation work when setting (for example, installing or setting the lighting state) lighting fixtures in a lighting space (for example, a stage, a theater, a studio, etc.).

[0022] As shown in Figure 1, the lighting control system 1 includes a lighting control device 10, a plurality of lighting fixtures installed in the lighting space #1, a plurality of battens to which the lighting fixtures are installed, and a plurality of nodes to which the lighting fixtures are connected.

[0023] The lighting control device 10 is a control device capable of communicating bidirectional control signals (for example, control signals corresponding to the RDM (Remote Device Management) standard) with lighting fixtures, and is generally referred to as a dimming control console or control console. When the lighting control device 10 receives an operation command for a lighting fixture from a user (for example, an operator operating the lighting control device 10), it generates a control signal that includes the universe (system) set on the node to which the lighting fixture is connected (more specifically, the port of the node to which the lighting fixture is connected) and the address (control address) set on the lighting fixture, and transmits the control signal to the node. The node converts the control signal received from the lighting control device 10 into, for example, a signal compliant with the RDM standard (RDM signal) and outputs it to the lighting fixture indicated by the universe and address. This controls the lighting fixture. In this way, the lighting control device 10 remotely controls the lighting fixture using, for example, the universe and address included in the RDM-compatible control signal.

[0024] The lighting fixture is capable of bidirectional communication with nodes and lighting control devices 10 using communication protocols compliant with the DMX (Digital Multiplex) standard or communication methods compliant with the RDM standard, which is an extension of DMX. The lighting fixture also has semiconductor light-emitting elements such as LEDs (Light Emitting Diodes) and performs lighting effects in studios, stages, etc., by changing brightness, range, color, etc., according to control signals. The lighting fixture is equipment installed in any space such as a studio or stage, and is mounted on a batten, which is equipment used to suspend lighting fixtures.

[0025] Note that lighting fixtures may have multiple addresses assigned to them. For example, if a lighting fixture can be individually configured for red, blue, and green light, then the fixture will have a total of three addresses, one for each color, and each color can be controlled individually through these addresses. In the following explanation, the address with the smallest value among the one or more addresses assigned to a lighting fixture may be referred to as the start address. Also, in the following explanation, the number of addresses assigned for controlling a lighting fixture may be referred to as the number of channels.

[0026] A node is a distributor that distributes control information that enables bidirectional communication with lighting fixtures and lighting control devices 10 using a communication protocol compliant with the DMX standard or a communication method compliant with the RDM standard, which is an extension of DMX. For example, a node is a device that relays communication between the lighting control device 10 and the lighting fixtures, and can be implemented by devices such as a DMX node or an RDM node.

[0027] To give a specific example, a node is connected to a hub via a wired or wireless network such as Ethernet (registered trademark) in a manner that enables bidirectional communication, and communicates with a lighting control device 10, etc., via the hub. The node also has multiple ports, and is connected to lighting fixtures via each port, and transmits and receives signals with the lighting fixtures, for example, in accordance with the RDM standard. Here, each port is assigned information to identify it (for example, a port number).

[0028] The following explanation will use Figure 1 to describe the process by which the lighting control device 10 sets the universe and address for each lighting fixture and the node to which the lighting fixture is connected. In the following explanation, it is assumed that battens B1 to B5 are installed in lighting space #1 shown in Figure 1, and that one node (nodes N1 to N5) is installed for each of the battens B1 to B5. Furthermore, in the following explanation, it is assumed that lighting fixtures connected to any node via ports provided on each node are installed on battens B1 to B5.

[0029] Furthermore, in the following description, it is assumed that the lighting control device 10 manages the correspondence between a node, the batten on which the node is installed, and the position of the batten in the lighting space #1 in its own storage unit.

[0030] Furthermore, in the following explanation, we will assume that the maximum number of addresses that can be set in a single universe is "512".

[0031] First, the lighting control device 10 collects lighting information from each lighting fixture installed in lighting space #1. For example, the lighting control device 10 collects lighting information such as information to identify the lighting fixture, information to identify the node to which the lighting fixture is connected, information to identify the port to which the lighting fixture is connected, and information indicating the number of channels of the lighting fixture.

[0032] Next, the lighting control device 10 sets a universe and an address associated with that universe for each lighting fixture and the node to which the lighting fixture is connected, based on the lighting information and predetermined rules. For example, based on the lighting information, the lighting control device 10 identifies which node installed on which batten each lighting fixture is connected to and via which port, and sets a universe and address for each lighting fixture and the node to which the lighting fixture is connected in accordance with predetermined rules.

[0033] Here, in the example in Figure 1, it is assumed that a rule is defined to set the universe and address for the lighting fixtures installed in each batten in the order of battens B1 to B5 (nodes N1 to N5). In such a case, the lighting control device 10 first identifies the lighting fixtures D11 to D13 that will be connected to node N1 of batten B1 based on the lighting information. Then, based on the lighting information, the lighting control device 10 identifies which port of node N1 each lighting fixture D11 to D13 will connect to, and sets the universe and address in order from the lighting fixture with the smallest port number of the port it connects to. In the example in Figure 1, the lighting control device 10 sets the universe and address for lighting fixtures D11 to D13 in that order.

[0034] For example, the lighting control device 10 first sets the universe to "1" for the port of node N1 to which lighting fixture D11 is connected. Then, since lighting fixture D11 has "3" channels, the lighting control device 10 sets sequential addresses "1" to "3" associated with universe "1" for lighting fixture D11, and sets the start address to "1".

[0035] Next, the lighting control device 10 sets the universe to "1" for the port of node N1 to which lighting fixture D12 is connected. Since lighting fixture D12 has "20" channels, the lighting control device 10 sets addresses "4" to "23" associated with universe "1" for lighting fixture D12, and sets the start address to "4".

[0036] Next, the lighting control device 10 sets the universe to "1" for the port of node N1 to which lighting fixture D13 is connected. Since lighting fixture D13 has "20" channels, the lighting control device 10 sets addresses "24" to "43" associated with universe "1" for lighting fixture D13, and sets the start address to "24".

[0037] Here, after setting the universe and address for the lighting fixtures connected to node N1 of baton B1, the lighting control device 10 identifies lighting fixtures D21 to D23 connected to node N2 of baton B2 based on the lighting information. Then, based on the lighting information, the lighting control device 10 identifies which port of node N2 each lighting fixture D21 to D23 will connect to, and sets the universe and address for each fixture in order from the lighting fixture with the smallest port number of the port it will connect to. In the example in Figure 1, the lighting control device 10 sets the universe and address for lighting fixtures D21 to D23 in that order.

[0038] For example, the lighting control device 10 first sets the universe to "1" for the port of node N2 to which lighting fixture D21 is connected. Then, since lighting fixture D21 has "3" channels, the lighting control device 10 sets sequential addresses "44" to "46" associated with universe "1" for lighting fixture D21, and sets the start address to "44".

[0039] Next, the lighting control device 10 sets the universe to "1" for the port of node N2 to which lighting fixture D22 is connected. Since lighting fixture D22 has "20" channels, the lighting control device 10 sets addresses "47" to "66" associated with universe "1" for lighting fixture D22, and sets the start address to "47".

[0040] Next, the lighting control device 10 sets the universe to "1" for the port of node N2 to which lighting fixture D23 is connected. Since lighting fixture D23 has "3" channels, the lighting control device 10 sets addresses "67" to "69" associated with universe "1" for lighting fixture D23, and sets the start address to "67".

[0041] The same process for setting the universe and address is then performed for each node in battens B3-B5, as well as for each lighting fixture connected to each node.

[0042] Here, we assume that the port of node N5 to which lighting fixture D51 is connected is set to universe "1", and that lighting fixture D51 is assigned addresses "505" to "507" associated with universe "1". Furthermore, we assume that lighting fixture D52, which will have its universe and address settings configured next to lighting fixture D51, has "20" channels. In this case, if we try to set the port of node N5 to which lighting fixture D52 is connected to universe "1", and then configure the address associated with universe "1" for lighting fixture D52, we will exceed the upper limit of "512" addresses in a single universe.

[0043] Therefore, the lighting control device 10 sets a new universe "2" for the port of node N5 to which lighting fixture D52 is connected. Then, the lighting control device 10 sets addresses "1" to "20" associated with universe "2" for lighting fixture D52, and sets the start address to "1". Next, the lighting control device 10 sets universe "2" for the port of node N5 to which lighting fixture D53, which will have its universe and address set after lighting fixture D52, is connected. Then, the lighting control device 10 sets addresses "21" to "40" associated with universe "2" for lighting fixture D53, and sets the start address to "21".

[0044] In other words, the lighting control device 10 first assigns sequential addresses to lighting fixtures, each associated with universe "1". Then, when the number of addresses associated with universe "1" reaches the upper limit, the lighting control device 10 assigns sequential addresses to the remaining lighting fixtures, each associated with a new universe "2".

[0045] The lighting control device 10 may also set a universe and an address associated with that universe for each lighting fixture. In such a case, the lighting control device 10 first collects lighting information from each lighting fixture installed in lighting space #1. For example, the lighting control device 10 collects lighting information such as information to identify the lighting fixture, information to identify the node to which the lighting fixture is connected, information to identify the port to which the lighting fixture is connected, and information indicating the number of channels of the lighting fixture.

[0046] Next, the lighting control device 10 sets a universe and an address associated with that universe for each lighting fixture based on the lighting information and predetermined rules. For example, based on the lighting information, the lighting control device 10 identifies which node installed on which batten each lighting fixture connects to via which port, and sets a universe and address for each lighting fixture in accordance with predetermined rules.

[0047] Here, in the example in Figure 1, it is assumed that a rule is defined to set the universe and address for the lighting fixtures installed in each batten in the order of battens B1 to B5 (nodes N1 to N5). In such a case, the lighting control device 10 first identifies the lighting fixtures D11 to D13 that are connected to node N1 of batten B1 based on the lighting information. Then, based on the lighting information, the lighting control device 10 identifies which port of node N1 each lighting fixture D11 to D13 will connect to, and sets the universe and address for the lighting fixtures in order from the one with the smallest port number of the port to which they will connect. In the example in Figure 1, the lighting control device 10 sets the universe and address for lighting fixtures D11 to D13 in that order.

[0048] For example, the lighting control device 10 first sets the universe and address for the lighting fixture D11. Here, since the lighting fixture D11 has "3" channels, the lighting control device 10 sets the lighting fixture D11 to universe "1" and sequential addresses "1" to "3" associated with universe "1", and sets the start address to "1".

[0049] Next, the lighting control device 10 sets the universe and address for the lighting fixture D12. Here, since the lighting fixture D12 has "20" channels, the lighting control device 10 sets the universe "1" and the addresses "4" to "23" associated with universe "1" for the lighting fixture D12, and sets the start address to "4".

[0050] Next, the lighting control device 10 sets the universe and address for the lighting fixture D13. Since the lighting fixture D13 has 20 channels, the lighting control device 10 sets the universe "1" and the addresses "24" to "43" associated with universe "1" for the lighting fixture D13, and sets the start address to "24".

[0051] Here, after setting the universe and address for the lighting fixtures connected to node N1 of baton B1, the lighting control device 10 identifies lighting fixtures D21 to D23 connected to node N2 of baton B2 based on the lighting information. Then, based on the lighting information, the lighting control device 10 identifies which port of node N2 each lighting fixture D21 to D23 will connect to, and sets the universe and address for each lighting fixture in order from the one with the smallest port number on the port it will connect to. In the example in Figure 1, the lighting control device 10 sets the universe and address for lighting fixtures D21 to D23 in that order.

[0052] For example, the lighting control device 10 first sets the universe and address for lighting fixture D21. Here, since lighting fixture D21 has "3" channels, the lighting control device 10 sets the universe "1" and sequential addresses "44" to "46" associated with universe "1" for lighting fixture D21, and sets the start address to "44".

[0053] Next, the lighting control device 10 sets the universe and address for the lighting fixture D22. Here, since the lighting fixture D22 has "20" channels, the lighting control device 10 sets the universe "1" and the addresses "47" to "66" associated with universe "1" for the lighting fixture D22, and sets the start address to "47".

[0054] Next, the lighting control device 10 sets the universe and address for the lighting fixture D23. Since the lighting fixture D23 has "3" channels, the lighting control device 10 sets the lighting fixture D23 to universe "1" and addresses "67" to "69" associated with universe "1", and sets the start address to "67".

[0055] The same process of setting the universe and address is then performed for the lighting fixtures connected to each node of baton B3 to B5.

[0056] Here, lighting fixture D51, which is connected to node N5 of baton B5, is set to universe "1" and addresses "505" to "507" associated with universe "1". The lighting fixture D52, which will be set to set the universe and address after lighting fixture D51, has a channel count of "20". In this case, if we try to set universe "1" for lighting fixture D52 and set the addresses associated with universe "1", we will exceed the upper limit of "512" for addresses in a single universe.

[0057] Therefore, the lighting control device 10 sets a new universe "2" and addresses "1" to "20" associated with universe "2" for lighting fixture D52, and sets the start address to "1". Furthermore, for lighting fixture D53, which will have a universe and address set after lighting fixture D52, the lighting control device 10 sets universe "2" and addresses "21" to "40" associated with universe "2", and sets the start address to "21".

[0058] In other words, the lighting control device 10 first assigns a universe "1" to each lighting fixture and then assigns sequentially numbered addresses associated with universe "1". When the number of addresses associated with universe "1" reaches its limit, the lighting control device 10 assigns a new universe "2" to the remaining lighting fixtures and assigns sequentially numbered addresses associated with universe "2".

[0059] Furthermore, the process of setting the universe and address for each lighting fixture is not limited to the methods described above and may be performed using any method. The process of setting the universe and address will now be explained using Figures 2 to 4.

[0060] First, we will explain the process of setting the universe and address for each node using Figure 2. Figure 2 is Figure (1) which shows an example of the universe and address setting process according to the embodiment.

[0061] In the example shown in Figure 2, the lighting control device 10 sets the universe "1" for each port of node N1. Then, the lighting control device 10 sets addresses associated with the universe "1" for lighting fixtures D11 to D13 connected to each port of node N1, in sequential order from lighting fixture D11 to D13.

[0062] Furthermore, the lighting control device 10 sets the universe "2" for each port of node N2. Then, the lighting control device 10 sets addresses associated with the universe "2" for lighting fixtures D21 to D23 connected to each port of node N2, in sequential order from lighting fixture D21 to D23.

[0063] In other words, the lighting control device 10 sets a universe for each node. Then, for each lighting fixture connected to the same node, the lighting control device 10 sets a sequential address associated with the universe set for that node.

[0064] The lighting control device 10 may also set a universe and an address associated with that universe for each lighting fixture, for each node. In this case, the lighting control device 10 sets the universe "1" for lighting fixtures D11 to D13 connected to node N1, and sets the addresses associated with universe "1" sequentially for lighting fixtures D11 to D13.

[0065] Furthermore, the lighting control device 10 sets the universe "2" for lighting fixtures D21 to D23 connected to node N2, and sets the addresses associated with universe "2" sequentially for lighting fixtures D21 to D23.

[0066] In other words, the lighting control device 10 sets the universe to be set for each lighting fixture for each node. Then, the lighting control device 10 sets sequential addresses for each lighting fixture connected to the same node.

[0067] Next, using Figure 3, we will explain the process of setting the universe and address according to the position of the baton (node) in lighting space #1. Figure 3 is Figure (2) showing an example of the universe and address setting process according to the embodiment.

[0068] In the example shown in Figure 3, battens B1 and B2 are pre-configured by the operator of the lighting control device 10 as the right-hand area of ​​lighting space #1, and battens B3 to B5 are pre-configured as the left-hand area of ​​lighting space #1. In this case, the lighting control device 10 sets different universes for nodes N1 and N2 of battens B1 and B2 and for battens B3 to B5.

[0069] For example, the lighting control device 10 sets universe "1" for each port of nodes N1 and N2, and assigns sequential addresses associated with universe "1" to each lighting fixture connected to each port of nodes N1 and N2. Furthermore, the lighting control device 10 sets universe "2" for each port of nodes N3 to N5, and assigns sequential addresses associated with universe "2" to each lighting fixture connected to each port of nodes N3 to N5.

[0070] The lighting control device 10 may also set a universe and an address associated with that universe for each lighting fixture, according to the position of the baton in lighting space #1. In this case, the lighting control device 10 sets universe "1" for the lighting fixtures connected to nodes N1 and N2, and sets sequential addresses associated with universe "1". The lighting control device 10 also sets universe "2" for the lighting fixtures connected to nodes N3 to N5, and sets sequential addresses associated with universe "2".

[0071] Next, Figure 4 will be used to explain the process of setting the universe and address according to the node's port. Figure 4 is Figure (3) showing an example of the universe and address setting process according to the embodiment.

[0072] In the example shown in Figure 4, the lighting control device 10 sets a different universe for each port to which a lighting fixture is connected. For example, the lighting control device 10 sets universe "1" for port P11 of node N1. Then, the lighting control device 10 sets addresses "1" to "3" associated with universe "1" for lighting fixture D11 connected to port P11.

[0073] Furthermore, the lighting control device 10 sets the universe "2" for port P12 of node N1. Then, the lighting control device 10 sets addresses "1" to "20" associated with universe "2" for the lighting fixture D12 connected to port P12.

[0074] Furthermore, the lighting control device 10 sets the universe "3" for port P13 of node N1. Then, the lighting control device 10 sets addresses "1" to "20" associated with universe "3" for the lighting fixture D13 connected to port P13.

[0075] The lighting control device 10 may also set a different universe and an address associated with each universe for each lighting fixture, depending on the port to which it is connected. In such a case, the lighting control device 10 sets the universe "1" and addresses "1" to "3" associated with universe "1" for lighting fixture D11 connected to node N1 via port P11. The lighting control device 10 also sets the universe "2" and addresses "1" to "20" associated with universe "2" for lighting fixture D12 connected to node N1 via port P12. The lighting control device 10 also sets the universe "3" and addresses "1" to "20" associated with universe "3" for lighting fixture D13 connected to node N1 via port P13.

[0076] As described above, the lighting control device 10 according to the embodiment sets a universe and an address associated with that universe for each lighting fixture and the node to which the lighting fixture is connected, based on lighting information relating to the lighting fixture and predetermined rules. This allows the lighting control device 10 according to the embodiment to easily set a universe relating to the lighting fixture.

[0077] Furthermore, traditionally, when setting addresses for lighting fixtures, it was necessary to be mindful of keeping the number of addresses within a single universe within a maximum limit (e.g., 512). In recent years, there have been cases where multiple lighting fixtures with multiple channels, such as moving lights, are used, and in such cases, managing universes and addresses can become complex.

[0078] Therefore, according to the lighting control device 10 of this embodiment, it is possible to set a universe and an address for each lighting fixture and the node to which the lighting fixture is connected without having to be aware of the management of the universe and addresses, thereby reducing the burden on workers who perform setup work such as installing and setting up lighting fixtures in the lighting space.

[0079] (Other embodiments) The above-described embodiment is merely an example, and the lighting control device 10 may perform various processes using various types of information. Examples of this are listed below.

[0080] [Regarding the addition or modification of lighting fixtures] When a new lighting fixture is connected to the lighting control system 1 due to the addition or modification of lighting fixtures, the lighting control device 10 may collect lighting information about the new lighting fixture and, based on the collected lighting information and predetermined rules, set a universe and an address associated with that universe for each of the new lighting fixtures and the nodes to which the new lighting fixture is connected.

[0081] For example, in the example shown in Figure 1, if a new lighting fixture D61 is connected to any node, the lighting control device 10 collects lighting information related to lighting fixture D61. The lighting control device 10 then sets a universe different from the one already set in the lighting control system 1 for the port of the node to which lighting fixture D61 is connected, and sets the address associated with that universe for lighting fixture D61. For example, if the number of channels for lighting fixture D61 is "3", the lighting control device 10 sets a universe "3" different from the universes "1" and "2" used in the example shown in Figure 1 (in other words, the universe already used before lighting fixture D61 was connected) for the port of the node to which lighting fixture D61 is connected, and sets the addresses "1" to "3" associated with universe "3" for lighting fixture D61.

[0082] The lighting control device 10 may also reconfigure the universe and address in the lighting control system 1 after the new lighting fixture D61 has been connected. For example, in the example in Figure 1, lighting fixture D61 is connected to node N1, and the lighting control device 10 configures the universe and address in the order of lighting fixtures D11-D13, lighting fixture D61, and lighting fixture D21. In this case, the lighting control device 10 sets the universe to "1" for the port of node N1 to which lighting fixture D13 is connected, and sets addresses "24" to "43" associated with universe "1" for lighting fixture D13, similar to the example shown in Figure 1. Then, the lighting control device 10 sets the universe to "1" for the port of node N1 to which lighting fixture D61 is connected, and sets addresses "44" to "46" associated with universe "1" for lighting fixture D61. Furthermore, the lighting control device 10 sets the universe "1" to the port of node N2 to which lighting fixture D21 is connected, and sets addresses "47" to "49" associated with universe "1" to lighting fixture D21.

[0083] In other words, the lighting control device 10 may reset the addresses associated with the universe in sequential order, including newly connected lighting fixtures.

[0084] The lighting control device 10 may also set a universe and an address associated with that universe for a new lighting fixture. For example, the lighting control device 10 sets a universe different from one already set in the lighting control system 1, and an address associated with that universe, for lighting fixture D61. For example, if the number of channels for lighting fixture D61 is "3", the lighting control device 10 sets a universe "3" different from the universes "1" and "2" used in the example shown in Figure 1, and addresses "1" to "3" associated with universe "3" for lighting fixture D61.

[0085] Furthermore, the lighting control device 10 may reconfigure the universe and address of each lighting fixture in the lighting control system 1 after the new lighting fixture D61 has been connected. For example, in the example in Figure 1, lighting fixture D61 is connected to node N1, and the lighting control device 10 sets the universe and address in the order of lighting fixtures D11~D13, lighting fixture D61, and lighting fixture D21. In this case, the lighting control device 10 sets the universe "1" and the addresses "24" to "43" associated with universe "1" for lighting fixture D13, similar to the example shown in Figure 1. The lighting control device 10 then sets the universe "1" and the addresses "44" to "46" associated with universe "1" for lighting fixture D61. The lighting control device 10 also sets the universe "1" and the addresses "47" to "49" associated with universe "1" for lighting fixture D21.

[0086] [Regarding linking to scenes] The lighting control device 10 may manage the universe set for each lighting fixture and the node to which the lighting fixture is connected, and the address associated with that universe, by associating them with a predetermined scene. For example, the lighting control device 10 associates the universe and address set for each lighting fixture and the node to which the lighting fixture is connected with scene #1 represented by lighting space #1 (for example, the subject to be filmed in lighting space #1 (e.g., a TV program) or the subject to be performed in lighting space #1 (e.g., a play or a live performance)) and stores (registers) them in the device's memory. Then, for example, if a user of the lighting control device 10 wants to recreate scene #1 in lighting space #1, they can recreate scene #1 by arranging each batten, each node, each lighting fixture, etc., in the same way as in scene #1, and by calling up the universe and address settings associated with scene #1 in the lighting control device 10. This eliminates the need to set the universe and address again in order to recreate scene #1, thus reducing the workload.

[0087] The lighting control device 10 may also manage the universe set for each lighting fixture and the address associated with that universe by associating them with a predetermined scene. For example, the lighting control device 10 associates the universe and address set for each lighting fixture with scene #1 indicated by lighting space #1 and stores (registers) them in the device's memory.

[0088] (An example of a lighting control device 10) Next, the configuration of the lighting control device 10 will be described using Figure 5. Figure 5 is a diagram showing an example of the configuration of the lighting control device 10 according to the embodiment. As shown in Figure 5, the lighting control device 10 has a communication unit 11, a display unit 12, an operation unit 13, a storage unit 14, and a control unit 15.

[0089] [Regarding Communications Section 11] The communication unit 11 is implemented, for example, by a NIC (Network Interface Card). The communication unit 11 then sends and receives information with lighting fixtures, nodes, etc., via a communication network such as Ethernet or LAN.

[0090] [Regarding the display unit 12] The display unit 12 is implemented, for example, by an LCD monitor or a touch panel, and displays an operation screen that accepts requests for operation of the lighting fixture.

[0091] [Regarding the control unit 13] The control unit 13 is implemented by input devices such as faders and buttons, and accepts operations from the operator. The control unit 13 may also be implemented by input devices for performing predetermined operations on one or more lighting fixtures, such as submaster faders, scene buttons, and effect buttons.

[0092] [Regarding memory unit 14] The storage unit 14 is implemented by, for example, semiconductor memory elements such as RAM (Random Access Memory) and flash memory, or by storage devices such as hard disks and optical discs. As shown in Figure 5, the storage unit 14 has a lighting information storage unit 141 and a scene information storage unit 142.

[0093] [Regarding the lighting information storage unit 141] The lighting information storage unit 141 stores various types of information related to lighting fixtures. Here, an example of the information stored by the lighting information storage unit 141 will be explained using Figure 6. Figure 6 is a diagram showing an example of the lighting information storage unit 141 according to the embodiment. In the example in Figure 6, the lighting information storage unit 141 has items such as "lighting space ID", "lighting fixture ID", "baton information", "node information", "universe information", and "address information".

[0094] "Lighting Space ID" indicates identification information for identifying the lighting space in which the lighting fixture is installed. "Lighting Fixture ID" indicates identification information for identifying the lighting fixture. "Baton Information" indicates information about the baton to which the lighting fixture is installed, for example, it stores identification information for identifying the baton. "Node Information" indicates information about the node to which the lighting fixture is connected, for example, it stores information such as identification information for identifying the node and information about the port to which the lighting fixture is connected (for example, port number). "Universe Information" indicates the universe set for the port to which the lighting fixture is connected. "Address Information" indicates the address set for the lighting fixture.

[0095] In other words, Figure 6 shows an example where a lighting fixture identified by lighting fixture ID "DID#1" is installed in a lighting space identified by lighting space ID "AID#1", and the baton information of the baton to which the lighting fixture is installed is "baton information#1", the node information is "node information#1", the universe information of the port to which the lighting fixture is connected is "universe information#1", and the address information is "address information#1".

[0096] [Regarding the scene information storage unit 142] The scene information storage unit 142 stores information about the scene represented by the lighting space. Here, an example of the information stored by the scene information storage unit 142 will be explained using Figure 7. Figure 7 is a diagram showing an example of the scene information storage unit 142 according to the embodiment. In the example in Figure 7, the scene information storage unit 142 has items such as "scene ID", "setting information", and "installation information".

[0097] "Scene ID" indicates identification information for identifying the scene. "Configuration Information" indicates the universe and address set for each lighting fixture and node to which the lighting fixture is connected in the scene. "Installation Information" indicates information about battens, nodes, lighting fixtures, etc., installed in the lighting space represented by the scene.

[0098] In other words, Figure 7 shows an example where the setting information for a scene identified by the scene ID "SID#1" is "Setting Information #1" and the installation information is "Installation Information #1".

[0099] [Regarding the control unit 15] The control unit 15 is a controller, and is realized by executing various programs stored in the internal memory of the lighting control device 10 using RAM as a working area, for example, by a CPU (Central Processing Unit) or MPU (Micro Processing Unit). Alternatively, the control unit 15 is a controller and can be realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array). As shown in Figure 5, the control unit 15 according to this embodiment has a data collection unit 151, a setting unit 152, and a management unit 153, and realizes or executes the information processing functions and operations described below.

[0100] [Regarding Collection Unit 151] The collection unit 151 collects lighting information from lighting fixtures that can communicate with the lighting control device 10. For example, in the example in Figure 1, the collection unit 151 collects lighting information from each lighting fixture installed in the lighting space #1 and stores (registers) it in the storage unit 14 (for example, the lighting information storage unit 141).

[0101] Furthermore, the collection unit 151 may also collect new lighting information relating to a new lighting fixture that has become able to communicate with the lighting control device. For example, in the example in Figure 1, when a new lighting fixture is connected to the lighting control system 1, the collection unit 151 collects lighting information relating to the new lighting fixture and stores it in the storage unit 14 (for example, the lighting information storage unit 141).

[0102] [Regarding setting section 152] The setting unit 152 sets a universe and an address associated with that universe for each lighting fixture and the node to which the lighting fixture is connected, based on the lighting information collected by the collection unit 151 and predetermined rules. For example, in the example in Figure 1, the setting unit 152 refers to the storage unit 14 (for example, the lighting information storage unit 141) and sets a universe and an address associated with that universe for each lighting fixture and the node to which the lighting fixture is connected, based on the lighting information and predetermined rules.

[0103] Alternatively, the configuration unit 152 may set a universe for each node and assign sequential addresses to the lighting fixtures that are associated with that universe. For example, in the example in Figure 1, the configuration unit 152 sets universe "1" for the port to which each lighting fixture is connected and assigns sequential addresses to each lighting fixture that are associated with universe "1".

[0104] The setting unit 152 may also set a universe "1" for each lighting fixture and set sequential addresses associated with universe "1".

[0105] Furthermore, the configuration unit 152 may set a first universe for each node and sequentially assign addresses to the lighting fixtures that are associated with the first universe. If the number of addresses associated with the first universe reaches the upper limit, the configuration unit 152 may set a second universe for the nodes to which the remaining lighting fixtures are connected and sequentially assign addresses to the second universe for the remaining lighting fixtures. For example, in the example in Figure 1, the configuration unit 152 sets universe "1" for the port to which each lighting fixture is connected and sequentially assigns addresses to universe "1" for each lighting fixture. Then, if the number of addresses associated with universe "1" reaches the upper limit, the configuration unit 152 sets a new universe "2" for the ports to which the remaining lighting fixtures are connected and sequentially assigns addresses to universe "2" for the remaining lighting fixtures.

[0106] The setting unit 152 may also set a universe "1" for each lighting fixture and assign sequential addresses to universe "1". If the number of addresses assigned to universe "1" reaches the upper limit, the setting unit 152 may set a new universe "2" for the remaining lighting fixtures and assign sequential addresses to universe "2".

[0107] Furthermore, the configuration unit 152 may set a universe and an address associated with that universe depending on the node to which the lighting fixture is connected. For example, in the example in Figure 2, the configuration unit 152 sets universe "1" for each port of node N1. Then, the configuration unit 152 sets addresses associated with universe "1" for lighting fixtures D11 to D13 connected to each port of node N1, in sequential order from lighting fixtures D11 to D13. Also, the configuration unit 152 sets universe "2" for each port of node N2. Then, the configuration unit 152 sets addresses associated with universe "2" for lighting fixtures D21 to D23 connected to each port of node N2, in sequential order from lighting fixtures D21 to D23.

[0108] Alternatively, the setting unit 152 may set universe "1" for lighting fixtures D11 to D13 connected to node N1, and set the addresses associated with universe "1" sequentially in the order of lighting fixtures D11 to D13. Furthermore, the setting unit 152 may set universe "2" for lighting fixtures D21 to D23 connected to node N2, and set the addresses associated with universe "2" sequentially in the order of lighting fixtures D21 to D23.

[0109] Furthermore, the configuration unit 152 may set a universe and an address associated with that universe according to the port of the node to which the lighting fixture is connected. For example, in the example in Figure 4, the configuration unit 152 sets universe "1" for port P11 of node N1. The lighting control device 10 then sets addresses "1" to "3" associated with universe "1" for lighting fixture D11 connected to port P11. The configuration unit 152 also sets universe "2" for port P12 of node N1. The configuration unit 152 then sets addresses "1" to "20" associated with universe "2" for lighting fixture D12 connected to port P12. The configuration unit 152 also sets universe "3" for port P13 of node N1. The configuration unit 152 then sets addresses "1" to "20" associated with universe "3" for lighting fixture D13 connected to port P13.

[0110] The configuration unit 152 may also configure the lighting fixture D11 connected via port P11 of node N1 with universe "1" and addresses "1" to "3" associated with universe "1". Furthermore, the configuration unit 152 may configure the lighting fixture D12 connected via port P12 of node N1 with universe "2" and addresses "1" to "20" associated with universe "2". Additionally, the configuration unit 152 may configure the lighting fixture D13 connected via port P13 of node N1 with universe "3" and addresses "1" to "20" associated with universe "3".

[0111] Furthermore, the setting unit 152 may set a universe and an address associated with that universe according to the location of the node to which the lighting fixture is connected. For example, in the example in Figure 3, the setting unit 152 sets universe "1" for each port of nodes N1 and N2 installed in the upper area of ​​lighting space #1, and sets sequential addresses associated with universe "1" for each lighting fixture connected to each port of nodes N1 and N2. Also, the setting unit 152 sets universe "2" for each port of nodes N3 to N5 installed in the lower area of ​​lighting space #1, and sets sequential addresses associated with universe "2" for each lighting fixture connected to each port of nodes N3 to N5.

[0112] The setting unit 152 may also set universe "1" and assign sequential addresses to lighting fixtures connected to nodes N1 and N2 installed in the upper-right area of ​​lighting space #1. Alternatively, the setting unit 152 may set universe "2" and assign sequential addresses to lighting fixtures connected to nodes N3 to N5 installed in the lower-right area of ​​lighting space #1.

[0113] Furthermore, when new lighting information is collected, the setting unit 152 may set a universe and an address associated with that universe for each of the new lighting fixtures and the nodes to which the new lighting fixtures are connected, based on the new lighting information and predetermined rules. For example, in the example in Figure 1, the setting unit 152 sets a universe for the nodes to which the new lighting fixtures are connected, and sets an address associated with that universe for the new lighting fixtures, based on the lighting information for the new lighting fixtures and predetermined rules.

[0114] The setting unit 152 may also set a universe and an address associated with the universe for a new lighting fixture based on lighting information related to the new lighting fixture and predetermined rules.

[0115] Furthermore, the setting unit 152 may set a different universe for each new lighting fixture and each node to which the new lighting fixture is connected, as well as an address associated with that universe. For example, in the example in Figure 1, the setting unit 152 sets a different universe "3" for the port of the node to which lighting fixture D61 is connected in the lighting control system 1, which is different from the universe already used before lighting fixture D61 was connected, and sets addresses "1" to "3" associated with universe "3" for lighting fixture D61.

[0116] The setting unit 152 may also set a different universe "3" and an address associated with universe "3" for the lighting fixture D61 in the lighting control system 1, which is different from the universe already used before connecting the lighting fixture D61.

[0117] Furthermore, the setting unit 152 may reset the universe and the address associated with the universe for each lighting fixture and the node to which the lighting fixture is connected, based on the lighting information, the new lighting information, and predetermined rules, and may also set the universe and the address associated with the universe for each new lighting fixture and the node to which the new lighting fixture is connected. For example, in the example in Figure 1, the setting unit 152 sets the universe "1" for the port of node N1 to which lighting fixture D13 is connected, and sets the addresses "24" to "43" associated with universe "1" for lighting fixture D13. Then, the setting unit 152 sets the universe "1" for the port of node N1 to which lighting fixture D61 is connected, and sets the addresses "44" to "46" associated with universe "1" for lighting fixture D61.

[0118] The setting unit 152 first sets the lighting fixture D13 with universe "1" and addresses "24" to "43" associated with universe "1", and then sets the lighting fixture D61 with universe "1" and addresses "44" to "46" associated with universe "1".

[0119] [Regarding Management Department 153] The management unit 153 manages the universe set for each lighting fixture and the node to which the lighting fixture is connected, and the address associated with that universe, by associating them with a predetermined scene. For example, in the example in Figure 1, the management unit 153 associates the universe set for each lighting fixture and the node to which the lighting fixture is connected, and the address associated with that universe, with scene #1 indicated by lighting space #1, and stores them in the storage unit 14 (for example, scene information storage unit 142).

[0120] The management unit 153 may also associate the universe and address set for each lighting fixture with scene #1 indicated by lighting space #1 and store them in the memory unit 14 (for example, scene information memory unit 142).

[0121] (Processing flow of the lighting control device 10) Next, the processing flow of the lighting control device 10 according to the embodiment will be explained using Figure 8. Figure 8 is a flowchart showing an example of the information processing procedure according to the embodiment.

[0122] As shown in Figure 8, the lighting control device 10 determines whether or not it has collected lighting information from a lighting fixture with which it can communicate (step S101). If lighting information has not been collected (step S101; No), the lighting control device 10 waits until it collects the lighting information.

[0123] On the other hand, if lighting information is collected (step S101; Yes), the lighting control device 10 sets a universe and an address associated with that universe for each lighting fixture and node to which the lighting fixture is connected, based on the collected lighting information and predetermined rules (step S102), and then terminates the process.
