[0009] The lighting control device (terminal device 30) described below comprises a memory unit 34 that links and stores, for each folder, a virtual art set to be placed in a three-dimensional simulated space that simulates the lighting space in which the lighting device 10 is installed, an identification unit 353 that identifies the art set linked to the folder from the memory unit 34 when a folder is selected, and a display control unit 355 that displays an icon of the art set identified by the identification unit 353 on a simulated space image of the simulated space viewed from a specified viewpoint.

[0010] In the lighting control device (terminal device 30) described below, the display control unit 355 displays the simulated space image in which an art set corresponding to an icon selected by an operator is arranged in the simulated space.

[0011] In the lighting control device (terminal device 30) described below, the storage unit 34 stores an art set in association with each folder newly created by the operator.

[0012] In the lighting control device (terminal device 30) described below, the storage unit 34 stores a folder configured of art sets that are frequently used by the operator.

[0013] The lighting control method described below includes a storage process for linking and storing, for each folder, a virtual art set to be placed in a three-dimensional simulated space that simulates the lighting space in which a lighting device is installed, a specification process for identifying an art set linked to the folder from the storage unit when a folder is selected, and a display control process for displaying an icon of the art set identified by the specification process on a simulated space image of the simulated space viewed from a specified viewpoint.

[0014] <Embodiment> Hereinafter, a detailed description will be given of a form for carrying out a lighting control device and a lighting control method according to the present application (hereinafter, referred to as an "embodiment") with reference to the drawings. Note that the lighting control device and the lighting control method according to the present application are not limited to the embodiment.

[0015] First, an overview of a lighting control system according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing a configuration example of a lighting control system according to an embodiment. The lighting control system 1 shown in Fig. 1 is a system that supports preparation work when setting up (installing and setting lighting conditions) lighting devices on a stage, theater, stage, studio, etc. Note that a stage, theater, stage, studio, etc. correspond to examples of lighting spaces.

[0016] As shown in Fig. 1, the lighting control system 1 includes a terminal device 30 and a plurality of lighting devices 101 to 109. The terminal device 30 is a lighting control device that controls each lighting device 10 in accordance with an operation by an operator. In the example shown in Fig. 1, the terminal device 30 is an operation console. Furthermore, the terminal device 30 may be any terminal, such as a smartphone, a tablet terminal, or a PC.

[0017] The terminal device 30 is connected to the lighting devices 101 to 109. For example, the lighting devices 101 to 109 are lighting devices capable of bidirectional communication with the terminal device 30 in accordance with the RDM standard, which is an extension of DMX. Note that the lighting devices 101 to 109 may perform bidirectional communication with the terminal device 30 via a DMX node (not shown).

[0018] Batons 201 to 203 are liftable batons that suspend lighting devices 101 to 109. For example, the height of lighting device 10 can be adjusted by an operator operating batons 201 to 203 through an operating unit (not shown).

[0019] The terminal device 30 controls the dimming of the lighting devices 101-109 and the raising and lowering of the batons 201-203 in accordance with operations by an operator such as a worker. In the following, when there is no need to distinguish between the lighting devices 101-109, they will be referred to as lighting device 10, and when there is no need to distinguish between the batons 201-203, they will be referred to as baton 20.

[0020] In the present disclosure, the terminal device 30 generates and displays a simulated space image in which a three-dimensional simulated space that simulates an illuminated space is viewed from a predetermined viewpoint. The terminal device 30 also accepts settings for the positions of multiple cameras to be placed in the simulated space. The terminal device 30 also generates and displays camera images of the simulated space captured by the multiple cameras whose settings have been accepted. The terminal device 30 also accepts operations related to lighting control of the lighting device 10 from an operator for the displayed simulated space image, and reflects the lighting control in the camera images.

[0021] In this way, in the present disclosure, a simulated space image capable of accepting lighting control settings is displayed together with a camera image, and the lighting control settings are reflected in the camera image, allowing the operator to easily understand how the lighting state of the set lighting control appears in the camera image.

[0022] In addition, the terminal device 30 accepts operations related to the setting of the art set from the operator for the displayed simulated space image, and reflects the setting of the art set in the camera image. For example, the terminal device 30 displays a window for the art set in the simulated space image, and displays an icon corresponding to the art set in the window.

[0023] The operator can select a desired icon from the window and place the art set corresponding to that icon at any position on the simulated space image. For example, there are cases where multiple programs are recorded in one studio. In such cases, different art sets are required for each program.

[0024] On the other hand, if icons corresponding to all of the art sets are displayed in the above-mentioned art set window, it may take time for the operator to find the desired icon from within the window.

[0025] Therefore, in the present disclosure, an icon corresponding to a desired art set is registered and managed for each folder. That is, for example, an operator can create a folder for each program and register the art set to be used in that program in that folder.

[0026] When creating a preparation drawing, the terminal device 30 displays the icons in the folder selected by the operator, thereby displaying the icon desired by the operator. Therefore, the terminal device 30 allows the operator to easily select the necessary art set.

[0027] Next, a configuration example of the terminal device 30 according to the embodiment will be described with reference to Fig. 2. Fig. 2 is a block diagram showing an example of a functional configuration of the terminal device according to the embodiment. As shown in Fig. 2, the terminal device 30 includes a communication unit 31, a display unit 32, an operation unit 33, a storage unit 34, and a control unit 35.

[0028] The communication unit 31 is implemented by a predetermined communication circuit such as a NIC (Network Interface Card), and performs data communication with the lighting device 10 via a communication network such as Ethernet (registered trademark) or a LAN.

[0029] The display unit 32 is implemented by, for example, a liquid crystal monitor or a touch panel, and displays an operation screen for accepting operations for each lighting device 10. The display unit 32 also displays the above-mentioned simulated space image, camera images, and the like.

[0030] The operation unit 33 is implemented by an input device such as a fader or a button, and receives operations from an operator. Note that the operation unit 33 may be implemented by an input device for performing a predetermined operation on one or more lighting devices 10, such as a sub-master fader, a scene button, an effect button, or the like.

[0031] The storage unit 34 is implemented by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, or a storage device such as a hard disk or an optical disk. In the example shown in Fig. 2, the storage unit 34 has a simulated space information storage unit 34a, a folder information storage unit 34b, and a set information storage unit 34c.

[0032] The simulated space storage unit 34a stores information about a simulated space that simulates an illuminated space. The information about the simulated space includes, for example, identification information for identifying the illuminated space, and information about the shape and size of the space.

[0033] The folder information storage unit 34b stores folder information. The folder information is information about art sets registered in each folder, which will be described later. An example of the folder information will now be described with reference to FIG. 3. FIG. 3 is a diagram showing an example of the folder information. As shown in FIG. 3, the folder information includes items such as "folder name" and "art set information."

[0034] "Folder name" is the name of each folder. "Art set information" is information about the art set registered in the corresponding folder. The example shown in the figure shows folders with the names "Basic," "Morning Drama," and "News," and indicates that "Art set #1," "Art set #2," and "Art set #3" are registered in each folder, respectively.

[0035] Here, "art set #1" corresponding to the folder named "basic" includes all art sets registered in the terminal device 30, while "art set #2" and "art set #3" corresponding to the folders "morning drama" and "news" respectively include art sets selected by the operator, for example. In other words, the operator can select and register art sets to be registered in folders such as "morning drama" and "news" from the art sets registered in the "basic" folder.

[0036] Returning to the explanation of Fig. 2, the set information storage unit 34c will be explained. The set information storage unit 34c stores set information regarding the set set in the simulated space. The set information is information including, for example, the arrangement of the lighting device 10, the art set, etc. set in the simulated space, lighting control, etc.

[0037] The control unit 35 is a controller that controls the entire lighting control system 1. For example, the control unit 35 can be implemented by a processor such as a central processing unit (CPU) or a micro processing unit (MPU). Alternatively, the control unit 35 may be implemented by an integrated circuit such as a field programmable gate array (FPGA) or an application specific integrated circuit (ASIC).

[0038] In the example of FIG. 2, the control unit 35 includes an acquisition unit 351, a reception unit 352, an identification unit 353, a generation unit 354, and a display control unit 355.

[0039] The acquisition unit 351 acquires various information. For example, the acquisition unit 351 acquires information about the simulated space and information about the lighting device 10 to be installed in the simulated space, and registers the information in the simulated space information storage unit 34a. The acquisition unit 351 also acquires information about the art set to be installed in the simulated space.

[0040] The reception unit 352 receives various information. For example, the reception unit 352 receives settings for the positions of multiple cameras to be placed in the simulated space. Specifically, the reception unit 352 receives the settings for the camera positions by receiving an operation by the operator on the simulated space image displayed on the display unit 32. For example, after receiving the settings for the camera positions, the reception unit 352 may generate and display a camera image captured by a camera of the simulated space, thereby receiving position adjustment. In other words, the operator can adjust the camera position while watching the camera image until it is positioned to become a target camera image.

[0041] The reception unit 352 also receives settings of the lighting device 10 to be installed in the simulated space. Specifically, the reception unit 352 receives an operation by an operator on the simulated space image displayed on the display unit 32, thereby receiving the settings of the lighting device 10.

[0042] The reception unit 352 also receives designation of an art set to be arranged in the simulated space from the operator. Specifically, as described below, the reception unit 352 displays an art set screen W1 (see FIG. 4) on the simulated space image displayed on the display unit 32, and receives designation of the type of art set and the position to arrange it from the art set screen W1.

[0043] At this time, a plurality of folders are displayed on the art set screen W1 displayed on the display unit 32, and when each folder is opened, icons of the art sets registered in the corresponding folder are displayed.

[0044] When a folder is selected, the identification unit 353 identifies a virtual art set linked to the folder from the storage unit 34. Specifically, when a folder in the art set screen W1 displayed on the display unit 32 is selected, the identification unit 353 refers to the folder information storage unit 34b and identifies the virtual art set linked to the folder.

[0045] The generating unit 354 generates a simulated space image based on the information about the simulated space stored in the simulated space storage unit 34a. Specifically, the generating unit 354 generates a simulated space image in which the simulated space in which the art set is arranged is viewed from a predetermined viewpoint. The predetermined viewpoint may be, for example, a viewpoint in which the simulated space is viewed from the front, or the position of the camera accepted by the accepting unit 352 may be used as the viewpoint.

[0046] Furthermore, the generation unit 354 generates, for each camera, a camera image of the simulated space captured from the camera position based on the camera position setting accepted by the acceptance unit 352. Specifically, the generation unit 354 generates a camera image of the simulated space in which the art set is arranged, captured by the camera.

[0047] The display control unit 355 controls the display of images displayed on the display unit 32. Specifically, the display control unit 355 displays the generated simulated space image on the display unit 32. The display control unit 355 may also superimpose and display the art set screen W1 or a camera image for each camera on a partial area of ​​the simulated space image.

[0048] Next, examples of screens displayed on the display unit 32 will be described with reference to Fig. 4 and Fig. 5. Fig. 4 and Fig. 5 are diagrams showing examples of screens displayed on the display unit 32.

[0049] First, Fig. 4 shows a state in which a simulated space image is displayed full screen. In Fig. 4, the lighting device 10 is virtually displayed in the simulated space image. The reception unit 352 receives an operation by an operator on the simulated space image shown in Fig. 4, thereby receiving a change in the position or attitude of the lighting device 10 and a change in the art set (addition, deletion, change in position or attitude, etc.). In Fig. 4, the lighting device 10 is turned off, but it may be displayed in an on state (illumination state).

[0050] Furthermore, as shown in Fig. 4, an art set screen W1 is displayed in a partial area of ​​the simulated space image. In the example shown in Fig. 4, the art set screen W1 includes folders f1 to f5.

[0051] Folder f1 is a folder named "Basic", folder f2 is a folder named "Morning Drama", folder f3 is a folder named "Daytime Information Program", and folder f4 is a folder named "Evening News Program".

[0052] Moreover, the folder f5 is a folder whose folder name is “Seasonal Programs.” In the example shown in Fig. 4, the folder f5 is selected, and an icon A5 of an art set linked to the folder f5 is displayed.

[0053] The operator can freely create these folders and register icons corresponding to art sets to the folders. This allows the operator to display the icons required for a preparation drawing by selecting a folder when creating the preparation drawing.

[0054] 5 shows an example of displaying a folder f11 with the folder name "high frequency of use." The icons registered in the "high frequency of use" folder f11 are icons corresponding to art sets that are frequently used by operators.

[0055] For example, the control unit 35 counts the number of times each art set is used, and registers, for example, the top few icons in the folder f11. In this way, by automatically generating the "high frequency of use" folder f11, it is possible to facilitate the selection of an art set by the operator.

[0056] Next, a process procedure executed by the terminal device 30 according to the embodiment will be described with reference to Fig. 6. Fig. 6 is a flowchart showing a process procedure executed by the terminal device 30 according to the embodiment. Note that, here, a series of process procedures when creating a folder will be described.

[0057] 6, first, the terminal device 30 accepts a folder creation request from an operator (step S101), and then the terminal device 30 determines a folder name based on the operator's operation (step S102).

[0058] Next, the terminal device 30 displays the folder in accordance with the operator's operation (step S103), and accepts the designation of an art set to be linked to the folder (step S104). Then, the terminal device 30 adds the designated art set to the folder (step S105), and ends the process.

[0059] As described above, the lighting control device (terminal device 30) according to the embodiment includes a storage unit 34 that stores, for each folder, a virtual art set to be arranged in a three-dimensional simulated space that simulates the lighting space in which the lighting device 10 is installed, in association with the folder, an identification unit 353 that identifies an art set associated with the folder from the storage unit 34 when a folder is selected, and a display control unit that displays an icon of the art set identified by the identification unit 353 on a simulated space image of the simulated space viewed from a predetermined viewpoint. This allows efficient preparation of the lighting space.

[0060] Although an embodiment of the present invention has been described, this embodiment is presented as an example and is not intended to limit the scope of the invention. This embodiment can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. This embodiment and its modifications are included in the scope of the invention and its equivalents described in the claims, as well as in the scope and gist of the invention.
