[0009] The lighting control device (terminal device 30) described below includes a generation unit 354 that generates a simulated space image of a three-dimensional simulated space that simulates the lighting space in which the lighting devices 10 are installed, viewed from a predetermined viewpoint position, and a display control unit 355 that highlights and displays, in the simulated space image, an overlapping lighting device, which is the lighting device 10 on the viewpoint side, among the lighting devices 10 that overlap when viewed from the viewpoint position.

[0010] In the lighting control device (terminal device 30) described below, the display control unit 355 includes a calculation unit 353 that calculates a non-overlapping viewpoint position, which is a viewpoint position where the lighting devices 10 do not overlap in the simulated space, and the display control unit 355 suggests the non-overlapping viewpoint position when displaying a simulated space image including overlapping lighting devices.

[0011] In the lighting control device (terminal device 30) described below, the display control unit 355 displays a button for moving the viewpoint position to a non-overlapping viewpoint position in the simulated space image, and when the button is selected, the simulated space image as seen from the non-overlapping viewpoint position is displayed.

[0012] In the lighting control device (terminal device 30) described below, the display control unit 355 displays a button for returning from the non-overlapping viewpoint position to the original viewpoint position, and when the button is selected, displays a simulated space image as seen from the original viewpoint position.

[0013] In the lighting control device (terminal device 30) described below, a display control unit 355 displays a menu screen on the overlapping lighting device, and moves the viewpoint position to a non-overlapping viewpoint position in response to an operation on the menu screen.

[0014] In a lighting control device (terminal device 30) described below, a display control unit 355 displays an individual setting screen that accepts settings for a lighting device hidden by an overlapping lighting device.

[0015] The lighting control method described below includes a generation step of generating a simulated space image of a three-dimensional simulated space that simulates the lighting space in which the lighting device 10 is installed, viewed from a predetermined viewpoint position, and a display control step of highlighting and displaying, in the simulated space image, an overlapping lighting device, which is the lighting device on the viewpoint side among the lighting devices that overlap when viewed from the viewpoint position.

[0016] <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.

[0017] 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.

[0018] 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.

[0019] 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).

[0020] 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).

[0021] 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.

[0022] 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.

[0023] In this manner, in the present disclosure, a simulated space image capable of accepting lighting control settings and a camera image are displayed together, and the lighting control settings are reflected in the camera image, so that the operator can easily understand how the lighting state of the set lighting control appears in the camera image. In other words, according to the lighting control device (terminal device 30) according to the embodiment, the lighting control settings can be changed while viewing the camera image, so that the lighting space can be efficiently prepared.

[0024] Furthermore, in the present disclosure, when the terminal device 30 displays a camera image taken of the simulated space from a specified camera position, if multiple lighting devices 10 appear to overlap from the camera position, the terminal device 30 displays the camera image with the lighting device 10 on the camera position side highlighted.

[0025] This allows the operator to easily recognize that there is another lighting device 10 behind the highlighted lighting device 10. In other words, the present disclosure allows the operator to properly grasp the lighting devices installed in the lighting space.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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 storage unit 34a, a scene information storage unit 34b, and a set information storage unit 34c.

[0031] 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.

[0032] The scene information storage unit 34b stores scene information, which is information related to a scene. The scene information is information related to each scene registered in the terminal device 30. For example, the scene information storage unit 34b stores, as scene information, information related to the position and angle of view of the camera, information related to the lighting content of the lighting device 10 (position, lighting control, etc.), and information related to the art set arranged in the simulated space. The art set information includes, for example, the name, shape, size, color, etc. of the art set. The art set information is registered in advance by, for example, an operator.

[0033] 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).

[0034] In the example of FIG. 2, the control unit 35 includes an acquisition unit 351, a reception unit 352, a calculation unit 353, a generation unit 354, and a display control unit 355.

[0035] The acquisition unit 351 acquires various information. For example, the acquisition unit 351 acquires information related to the lighting space. The information related to the lighting space includes, for example, information on the shape and size of the lighting space, the position of the lighting device 10, and the like. The acquisition unit 351 also acquires art set information.

[0036] 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.

[0037] The receiving unit 352 also receives designation of an art set to be arranged in the simulated space from the operator. Specifically, the receiving unit 352 receives designation of the type of art set and the position to arrange it.

[0038] The calculation unit 353 calculates various information. For example, the calculation unit 353 calculates lighting devices 10 that overlap when viewed from the viewpoint position in the simulated space. For example, the calculation unit 353 calculates the inclinations of the line segments between the viewpoint and the lighting devices 10, and detects lighting devices 10 that overlap when viewed from the viewpoint position when there are multiple similar inclinations.

[0039] Furthermore, the calculation unit 353 calculates a non-overlapping viewpoint position, which is a viewpoint position where the lighting devices do not overlap in the simulated space. For example, the calculation unit 353 draws a diagonal line that connects the overlapping lighting devices 10 and goes perpendicular from the center of the line segment, and calculates a viewpoint position that falls within the angle of view as the non-overlapping viewpoint position.

[0040] 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.

[0041] 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.

[0042] 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 also displays the camera image for each camera in a superimposed manner on a partial area of ​​the simulated space image. Note that examples of screens displayed by the display control unit 355 will be described in detail later with reference to FIG. 4 and subsequent figures.

[0043] Next, examples of screens displayed on the display unit 32 will be described with reference to Fig. 3 to Fig. 8. Fig. 3 to Fig. 8 are diagrams showing examples of screens displayed on the display unit 32.

[0044] First, Fig. 3 shows a state in which a simulated space image is displayed on the full screen. In the example shown in Fig. 3, a total of four lighting devices 10, namely, lighting devices 10a to 10d, are installed in the simulated space. Also, in the example shown in Fig. 3, the current simulated space image shows a case in which the lighting devices 10a to 10d are displayed without overlapping with each other.

[0045] On the other hand, for example, when viewing the lighting device 10a from viewpoint position A1 shown in FIG. 3 along the arrow shown in FIG. 3, the lighting devices 10a to 10d overlap with each other from viewpoint position A1, and only the lighting device 10a is visible, as shown in FIG. 4.

[0046] 4, the operator cannot recognize the existence of the lighting devices 10b to 10d hidden by the lighting device 10a. Therefore, the display control unit 355 highlights in the simulated space image the overlapping lighting devices 10, which are the lighting devices 10 on the viewpoint side among the lighting devices 10 that overlap when viewed from the viewpoint.

[0047] In the example shown in the figure, the lighting device 10a located at the forefront is highlighted by applying hunting to the lighting device 10a. Note that the actual highlighting may be achieved by changing the color of the lighting device 10a or by blinking the lighting device 10a.

[0048] Furthermore, as shown in FIG. 5, a button for moving the viewpoint position to a non-overlapping viewpoint position may be displayed for the lighting device 10a located at the forefront. In the example of FIG. 5, arrows ar1 to ar4 are displayed as the buttons for moving the viewpoint position to a non-overlapping viewpoint position.

[0049] For example, when the operator selects any of the arrows ar1 to ar4, a simulated space image in which the lighting device 10 is viewed from the direction of the arrow is displayed. More specifically, when the arrow ar1 is selected, a simulated space image in which the simulated space is viewed from above the lighting device 10a is displayed, and when the arrow ar2 is selected, a simulated space image in which the simulated space is viewed from the right side of the lighting device 10a on the page is displayed.

[0050] When the arrow ar3 is selected, a simulated space image in which the simulated space is viewed from below the lighting device 10a is displayed, and when the arrow ar4 is selected, a simulated space image in which the simulated space is viewed from the left side of the lighting device 10a on the page is displayed.

[0051] That is, by displaying these buttons, the operator can easily change the viewpoint position to a non-overlapping viewpoint position.

[0052] These buttons may be displayed as a menu screen W1 as shown in Fig. 6. In the example shown in Fig. 6, "upward oblique viewpoint movement", "downward oblique viewpoint movement", "right oblique viewpoint movement" and "left oblique viewpoint movement" are displayed on the menu screen W1. When the operator selects one of these buttons, a simulated space image in which the viewpoint position has been moved in the corresponding direction is displayed.

[0053] Furthermore, for example, when the viewpoint is moved to a non-overlapping viewpoint position by a selection operation of the operator, a return button arb is displayed on the simulated space image as shown in Fig. 7. For example, the return button arb is associated with a command for returning the viewpoint position to the original viewpoint position.

[0054] That is, by the operator selecting the back button arb, it is possible to display the simulated space image of the arrows ar1 to ar4 (see FIG. 5) or the menu screen W1 (see FIG. 6) as viewed from the viewpoint position before the selection.

[0055] Also, for example, an individual setting screen W2 may be displayed on the simulated space image. The individual setting screen W2 is a window in which the lighting devices 10b to 10d hidden by the lighting device 10a in the simulated space image can be individually set. For example, the operator can arbitrarily set the arrangement of the lighting devices 10b to 10d using the individual setting screen W2.

[0056] That is, by displaying the individual setting screen W2, the operator can set the lighting devices 10b to 10d that are hidden by the lighting device 10a while maintaining the current viewpoint position.

[0057] Next, a process procedure executed by the terminal device 30 according to the embodiment will be described with reference to Fig. 9. Fig. 9 is a flowchart showing a process procedure executed by the terminal device 30 according to the embodiment.

[0058] 9, first, the terminal device 30 accepts the setting of the viewpoint position in the simulated space (step S101). Next, the terminal device 30 determines whether or not there is an overlapping lighting device 10 as viewed from the viewpoint position (step S102).

[0059] Next, when it is determined that there is an overlapping lighting device 10 (step S102; Yes), the terminal device 30 emphasizes the overlapping lighting device 10 that is closer to the viewpoint position among the overlapping lighting devices 10 (step S103).

[0060] If the terminal device 30 determines in step S102 that there is no overlapping lighting device 10 (step S102; No), the terminal device 30 skips the process of step S103. Then, the terminal device 30 generates a simulated space image of the simulated space viewed from the viewpoint position (step S104), and ends the process.

[0061] As described above, the lighting control device (terminal device 300) according to the embodiment includes a generation unit 354 that generates a simulated space image of a three-dimensional simulated space that shows a simulated lighting space in which the lighting devices 10 are installed, viewed from a predetermined viewpoint position, and a display control unit 355 that highlights and displays an overlapping lighting device, which is a lighting device 10 on the viewpoint side, among the lighting devices 10 that overlap when viewed from the viewpoint position, in the simulated space image. This allows the lighting devices installed in the lighting space to be properly recognized.

[0062] 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.
