[0015] Furthermore, when the display mode of an icon satisfies a predetermined condition, the display control unit 152 according to the embodiment described below rearranges the icon to a position corresponding to the changed viewpoint without rotating it, and displays new display content in which the text information has been rearranged without being rotated.

[0016] Moreover, the output unit 151 according to the embodiment described below outputs display content in which icons and text information are arranged in a two-dimensional space.

[0017] Moreover, the output unit 151 according to the embodiment described below outputs display content in which icons and text information are arranged in a three-dimensional space.

[0018] Moreover, the output unit 151 according to the embodiment described below outputs display content on a screen for controlling lighting fixtures.

[0019] (Example of a lighting control system) An example of a lighting control system will be described using 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 a system that supports preparation work when setting up (for example, installing or setting up lighting conditions) a lighting device in a lighting space (for example, a stage, a theater, a studio, etc.).

[0020] 1, lighting control system 1 includes lighting control device 10, lighting devices 20A-20O installed in lighting space #1, and batons 30A-30C from which lighting devices 20A-20O are suspended. In the following description, when the lighting devices 20A-20O are described without distinction, they may be referred to as "lighting devices 20." In the following description, when the batons 30A-30C are described without distinction, they may be referred to as "batons 30."

[0021] The lighting control device 10 is a device that controls the lighting devices 20 and batons 30 in accordance with operations by an operator. In the example shown in Fig. 1, the lighting control device 10 is a small dimming console that has a screen (display unit 12) and is portable by the operator. The lighting control device 10 may also be any terminal device, such as a smartphone, tablet terminal, or PC (Personal Computer).

[0022] Furthermore, lighting control device 10 is connected to lighting device 20. For example, lighting device 20 is a lighting device that can control the intensity (dimming level) of light output from light-emitting elements, the color of the output light, the irradiation direction, the lighting range, etc., based on control signals such as DMX signals received from lighting control device 10 or RDM signals based on the RDM standard, which is an extension of the DMX standard, and illuminates a predetermined position in lighting space #1 according to the received control signals.

[0023] Batons 30A to 30C are elevating batons that suspend lighting devices 20 in lighting space #1. For example, lighting control device 10 controls lighting devices 20 and also controls the elevation and lowering of batons 30A to 30C in accordance with operations from an operator.

[0024] In the example of FIG. 1 , lighting control device 10 manages, in a storage unit (e.g., space information storage unit 141) of its own device, information about the installation locations of lighting devices 20 and batons 30 in lighting space #1, text information indicating lighting devices 20 and batons 30 (e.g., identification information for identifying each lighting device 20 and each baton 30), and angle information indicating the angles (orientations) of lighting devices 20 and batons 30. When an operator carries lighting control device 10 and moves to lighting space #1 to use lighting control device 10, lighting control device 10 outputs display content to a screen of its own device, the display content including icons indicating lighting devices 20 and batons 30 and text information about lighting devices 20 and batons 30, based on the operator's viewpoint in lighting space #1. For example, lighting control device 10 outputs the display content on a screen for controlling lighting devices 20 and batons 30. In other words, the operator can control lighting devices 20 and batons 30 by performing a predetermined operation on the display content.

[0025] Here, the display content output on the screen by lighting control device 10 will be described with reference to Fig. 2. Fig. 2 is a diagram (1) showing an example of a screen of lighting control device 10 according to an embodiment.

[0026] In the example shown in FIG. 2, the lighting control device 10 receives a designation of a viewpoint (in other words, the position of the lighting control device 10) from the operator. In the example of FIG. 2, it is assumed that viewpoint P1 shown in FIG. 1 has been designated. In this case, display content C11 is displayed (output) on the screen, showing a plan view of lighting space #1 as seen from above, with viewpoint P1 being at the bottom of the view. For example, the lighting control device 10 displays display content C11 in which icons representing the lighting devices 20 and the batons 30 are placed at positions corresponding to the installation locations of the lighting devices 20 and the batons 30 in lighting space #1, and text information relating to the lighting devices 20 and the batons 30 is placed around the icons.

[0027] As a specific example, lighting control device 10 displays rectangular icons representing lighting devices 20A-20E superimposed on a bar-shaped icon representing baton 30A from which lighting devices 20A-20E are suspended. Lighting control device 10 also displays rectangular icons representing lighting devices 20F-20J superimposed on a bar-shaped icon representing baton 30B from which lighting devices 20F-20J are suspended. Lighting control device 10 also displays rectangular icons representing lighting devices 20K-20O superimposed on a bar-shaped icon representing baton 30C from which lighting devices 20K-20O are suspended. Lighting control device 10 also displays text information corresponding to each lighting device above each icon representing a lighting device 20. Lighting control device 10 also displays text information corresponding to each baton to the left of each icon representing a baton 30.

[0028] Here, it is assumed that the operator moves within lighting space #1 and lighting control device 10 receives an operation to change the viewpoint from viewpoint P1 shown in Fig. 1 to viewpoint P2. In this case, lighting control device 10 displays on the screen new display content C12 showing a plan view of lighting space #1 seen from above, with viewpoint P2 at the bottom of the view. For example, display content C12 is displayed in which icons corresponding to lighting devices 20 and batons 30 and text information related to lighting devices 20 and batons 30 are rearranged to positions corresponding to the changed viewpoint P2.

[0029] As a specific example, similar to display content C11, lighting control device 10 displays each icon representing a lighting device 20 superimposed on an icon representing a baton 30 from which the lighting device 20 is suspended. Furthermore, lighting control device 10 displays text information corresponding to each lighting device to the right of each icon representing a lighting device 20. Furthermore, lighting control device 10 displays text information corresponding to each baton above each icon representing a baton 30. Furthermore, lighting control device 10 displays the angle of each icon corresponding to a lighting device 20 without changing it from display content C11. Furthermore, lighting control device 10 displays the angle of each text information related to the lighting device 20 and the baton 30 without changing it from display content C11.

[0030] In the display content of lighting control device 10, the icons of lighting devices 20 may not be simply rectangular, but may be icons that allow identification of the shape and angle (orientation) of lighting device 20. Another example of display content output to the screen by lighting control device 10 will now be described with reference to Fig. 3. Fig. 3 is a diagram (2) illustrating an example of a screen of lighting control device 10 according to an embodiment.

[0031] 3, when the operator designates viewpoint P1 shown in FIG. 1, display content C21 showing a plan view of lighting space #1 as seen from above, with viewpoint P1 being at the bottom of the view, is displayed on the screen. For example, lighting control device 10 displays display content C21 in which each icon corresponding to lighting device 20 in display content C11 is replaced with an icon that schematically illustrates the shape of lighting device 20. In this case, lighting control device 10 arranges each icon corresponding to lighting device 20 in accordance with the orientation of lighting device 20 at viewpoint P1, based on angle information of lighting device 20.

[0032] Here, it is assumed that the operator moves within lighting space #1 and lighting control device 10 receives an operation to change the viewpoint from viewpoint P1 shown in Fig. 1 to viewpoint P2. In this case, lighting control device 10 displays on the screen new display content C22 showing a plan view of lighting space #1 seen from above, with viewpoint P2 at the bottom of the view. For example, display content C22 is displayed in which icons corresponding to lighting devices 20 and batons 30 and text information related to lighting devices 20 and batons 30 are rearranged to positions corresponding to the changed viewpoint P2.

[0033] As a specific example, the lighting control device 10 rearranges and displays each icon corresponding to the lighting device 20 according to the orientation of the lighting device 20 at the viewpoint P2. Note that the arrangement of other icons and text information is the same as that of the display content C12, and therefore a description thereof will be omitted.

[0034] As described above, lighting control device 10 according to the embodiment displays display content in which icons representing lighting fixtures and text information about lighting fixtures are arranged according to the viewpoint specified by the operator, and when the viewpoint is changed, displays display content in which the icons and text information are rearranged according to the changed viewpoint. This allows lighting control device 10 according to the embodiment to easily identify lighting fixtures when the viewpoint is changed.

[0035] Furthermore, conventionally, when operating lighting fixtures, a lighting control console was installed in a dedicated room separate from the lighting space (for example, a lighting control room in a theater or a sub-control room in a television studio), and lighting fixtures were often operated from that room. However, in recent years, with the emergence of detachable lighting control consoles and compact lighting control consoles, there has been an increase in situations in which operators carry a lighting control console into the lighting space to set up lighting fixtures and perform productions. In such cases, the lighting control console displays an image of the lighting space based on the viewpoint from a dedicated room such as a lighting control room or sub-control room, and when the operator moves to a different viewpoint, the image of the lighting space displayed on the lighting control console may diverge from the image of the lighting space from the operator's position.

[0036] Therefore, the lighting control device 10 of the embodiment can display icons representing lighting fixtures and display content in which text information about the lighting fixtures is arranged according to the viewpoint specified by the operator, so that even when the operator moves to the lighting space and operates the dimming control console, a natural GUI (Graphical User Interface) can be provided to the operator.

[0037] (Other embodiments) The above-described embodiment is merely an example, and the lighting control device 10 may perform various processes using various information. In this regard, examples will be listed below.

[0038] [About perspective] In the above example, viewpoint P1 is rotated 90 degrees to viewpoint P2, but the viewpoint change is not limited to this example. For example, lighting control device 10 may accept a viewpoint change in increments of 1 degree or 45 degrees. Furthermore, when lighting control device 10 accepts an operation to change the viewpoint from an operator, it may display display content in which icons and text information have been rearranged according to the viewpoint corresponding to the position of the lighting control device.

[0039] [About the displayed content] In the above example, display content in which icons and text information are arranged in a plan view of lighting space #1 viewed from above (in other words, a two-dimensional space) is displayed, but the display content is not limited to this example. For example, lighting control device 10 may display display content in which icons and text information are arranged in a three-dimensional space representing lighting space #1. When lighting control device 10 receives an operation to change the viewpoint of the display content, it may rearrange the icons in the three-dimensional space representing lighting space #1 to positions corresponding to the changed viewpoint, and display new display content in which the text information has been rearranged, depending on the operation.

[0040] [Display mode of display content] The display mode of the display content is not limited to the above-described example. For example, lighting control device 10 may display the display content in a mode corresponding to an operation by an operator. As a specific example, lighting control device 10 may move the display content in a direction in which the operator performs a predetermined operation on the screen (e.g., a drag operation). Furthermore, lighting control device 10 may enlarge or reduce the display content in response to a predetermined operation on the screen (e.g., a pinch-in or pinch-out) by the operator.

[0041] (Example of a lighting control device) Next, the configuration of lighting control device 10 will be described using Fig. 4. Fig. 4 is a diagram showing an example configuration of lighting control device 10 according to an embodiment. As shown in Fig. 4, lighting control device 10 has communication unit 11, display unit 12, operation unit 13, storage unit 14, and control unit 15.

[0042] [About Communications Section 11] The communication unit 11 is realized by, for example, a network interface card (NIC), etc. The communication unit 11 transmits and receives information to and from the lighting device 20, the baton 30, etc. via a communication network such as Ethernet (registered trademark) or a LAN.

[0043] [About display 12] Display unit 12 is implemented by, for example, a liquid crystal monitor or a touch panel, and displays illumination device 20, an operation screen for accepting operations on baton 30, etc. Display unit 12 also displays the above-mentioned display content.

[0044] [About operation unit 13] The operation unit 13 is implemented by an input device such as a fader or a button, and receives operations from an operator. Note that the operation unit 13 may also be implemented by an input device for performing predetermined operations on one or more lighting devices 20, such as a submaster fader, a scene button, or an effect button.

[0045] [Regarding the memory unit 14] The storage unit 14 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. As shown in FIG. 4, the storage unit 14 has a spatial information storage unit 141.

[0046] [Regarding the spatial information storage unit 141] The space information storage unit 141 stores various types of information related to lighting fixtures (for example, lighting devices 20, batons 30, etc.) installed in the lighting space. Here, an example of information stored in the space information storage unit 141 will be described with reference to FIG. 5. FIG. 5 is a diagram showing an example of the space information storage unit 141 according to the embodiment. In the example of FIG. 5, the space information storage unit 141 has items such as "lighting space ID," "lighting fixture ID," "installation location information," "text information," and "angle information."

[0047] "Lighting fixture ID" indicates identification information for identifying the lighting space in which the lighting fixture is installed. "Installation location information" indicates information indicating the location in the lighting space where the lighting fixture is installed (for example, information indicating the coordinates in the lighting space). "Text information" indicates text information related to the lighting fixture, and stores information such as the identification information and name of the lighting fixture. "Angle information" indicates the angle of the lighting fixture.

[0048] That is, Figure 5 shows an example in which, in an illumination space identified by an illumination space ID "AID#1," an illumination fixture identified by an illumination fixture ID "DID#1" is installed in the illumination space at a position indicated by installation location information "installation location information #1," and the character information is "character information #1," and the accuracy information is "angle information #1."

[0049] [Regarding control unit 15] The control unit 15 is a controller, and is realized by, for example, a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) executing various programs stored in a storage device inside the lighting control device 10 using RAM as a work area. The control unit 15 is also a controller, and is realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array). As shown in FIG. 4, the control unit 15 according to the embodiment has an output unit 151 and a display control unit 152, and realizes or executes the functions and actions of information processing described below.

[0050] [About output unit 151] The output unit 151 outputs display content in which an icon representing a lighting fixture is placed at a position corresponding to the installation location of the lighting fixture, and text information related to the lighting fixture is placed around the icon. For example, in the example of Fig. 2, the output unit 151 references the space information storage unit 141 and displays display content C11 in which icons representing the lighting device 20 and the baton 30 are placed at positions corresponding to the installation locations of the lighting device 20 and the baton 30 in lighting space #1, and text information related to the lighting device 20 and the baton 30 is placed around the icons.

[0051] Furthermore, the output unit 151 may output display content in which icons and text information are arranged in a two-dimensional space. For example, in the example of Fig. 2, the output unit 151 displays display content C11 in which icons representing the lighting devices 20 and the batons 30 and text information relating to the lighting devices 20 and the batons 30 are arranged on a plan view of the lighting space #1 seen from above.

[0052] Furthermore, the output unit 151 may output display content in which icons and text information are arranged in a three-dimensional space. For example, the output unit 151 displays display content in which icons and text information are arranged in a three-dimensional space representing the illumination space #1.

[0053] Furthermore, the output unit 151 may output the display content on a screen for controlling a lighting fixture. For example, the output unit 151 outputs the display content on a screen for controlling the lighting device 20 and the baton 30.

[0054] [Regarding the display control unit 152] When the display control unit 152 receives an operation to change the viewpoint of the display content, the display control unit 152 rearranges the icons to positions corresponding to the changed viewpoint according to the operation content, and displays new display content in which the text information has been rearranged without being rotated. For example, in the example of Fig. 2, the output unit 151 refers to the spatial information storage unit 141 and displays display content C12 in which the icons corresponding to the lighting device 20 and the baton 30 and the text information related to the lighting device 20 and the baton 30 have been rearranged to positions corresponding to the changed viewpoint P2.

[0055] Furthermore, when the display control unit 152 receives an operation to select one of the predetermined viewpoints, the display control unit 152 may rearrange the icon to a position corresponding to the selected viewpoint and display new display content in which the character information has been rearranged without being rotated. For example, in the example of Fig. 2, the output unit 151 displays display content C12 in which the angle of each piece of character information related to the lighting device 20 and the baton 30 has been rearranged without changing it from that of display content C11.

[0056] Furthermore, display control unit 152 may rearrange the icon to a position corresponding to a viewpoint corresponding to the position information of the lighting control device, and may display new display content in which the text information has been rearranged without rotating it. For example, when output unit 151 receives an operation to change the viewpoint from the operator, it displays display content in which the icon and text information have been rearranged according to the viewpoint corresponding to the position of the lighting control device.

[0057] Furthermore, the display control unit 152 may rearrange the icons to positions corresponding to the changed viewpoint without rotating them, and may display new display content in which the character information has been rearranged without rotating it. For example, in the example of Fig. 2, the output unit 151 displays display content C12 in which the angles of the icons corresponding to the lighting devices 20 have been rearranged without changing them from those of the display content C11.

[0058] Furthermore, when the display mode of the icon satisfies a predetermined condition, the display control unit 152 may rearrange the icon to a position corresponding to the changed viewpoint without rotating it, and may display new display content in which the character information has been rearranged without rotating it. For example, as shown in Fig. 2, when the icon of the lighting device 20 is a simple rectangle, the output unit 151 displays display content C12 in which the angle of each icon corresponding to the lighting device 20 is rearranged without changing it from display content C11. Furthermore, as shown in Fig. 3, when the icon is one in which the shape and angle of the lighting device 20 can be distinguished, the output unit 151 rearranges each icon corresponding to the lighting device 20 in accordance with the orientation of the lighting device 20 at viewpoint P2 (in other words, rotates and rearranges the icon).

[0059] (Processing flow of lighting control device 10) Next, a processing flow of the lighting control device 10 according to the embodiment will be described with reference to Fig. 6. Fig. 6 is a flowchart showing an example of the procedure of information processing according to the embodiment.

[0060] 6, lighting control device 10 outputs display content in which an icon representing a lighting fixture is placed at a position corresponding to the installation location of the lighting fixture, and text information about the lighting fixture is placed around the icon (step S101). Next, lighting control device 10 determines whether an operation to change the viewpoint has been accepted (step S102). If an operation to change the viewpoint has not been accepted (step S102; No), lighting control device 10 waits until an operation to change the viewpoint is accepted.

[0061] On the other hand, if an operation to change the viewpoint is received (step S102; Yes), the lighting control device 10 rearranges the icon to a position corresponding to the changed viewpoint according to the operation content, and displays new display content in which the text information has been rearranged without being rotated (step S103), and then terminates the processing.

[0062] (Variation) The above-described embodiment is merely an example, and various modifications and applications are possible.

[0063] [About the display target of display content] In the above embodiment, examples have been shown in which the display objects in the display content are lighting devices and batons, but the display objects are not limited to these examples. For example, the lighting control device 10 may display display content that includes an icon corresponding to any device installed on a stage or in a studio, or text information related to the device.

[0064] (Regarding processing mode) Of the processes described in the above embodiments, all or part of the processes described as being performed automatically can be performed manually, and conversely, all or part of the processes described as being performed manually can be performed automatically using known methods. In addition, the information, including the processing procedures, specific names, various data, and parameters shown in the above text and drawings, can be changed as desired unless otherwise specified. For example, the various information shown in each drawing is not limited to the information shown in the drawings.

[0065] Furthermore, the components of each device shown in the figure are conceptual functional components and do not necessarily have to be physically configured as shown in the figure. In other words, the specific form of distribution and integration of each device is not limited to that shown in the figure, and all or part of them can be functionally or physically distributed and integrated in any unit depending on various loads, usage conditions, etc.

[0066] Furthermore, the above-described embodiments can be combined as appropriate within the scope of not causing any contradiction in the processing content. [Explanation of symbols]
