[0009] [Figure 1] This is a schematic block diagram showing a lighting control device according to an embodiment. [Figure 2] This is an explanatory diagram schematically showing an example of an operation screen according to the embodiment. [Figure 3] This is an explanatory diagram schematically showing a modified example of the operation screen according to the embodiment. [Figure 4] Figures 4(a) to 4(f) are schematic explanatory diagrams illustrating modified examples of the icons according to the embodiment. [Modes for carrying out the invention]

[0010] Each embodiment will be described below with reference to the drawings. Please note that the drawings are schematic or conceptual, and the relationships between the thickness and width of each part, as well as the ratios of the sizes of the parts, are not necessarily identical to those of reality. Furthermore, even when representing the same part, the dimensions and ratios may differ between drawings. In this specification and in each figure, elements similar to those described above are denoted by the same reference numerals, and detailed explanations are omitted as appropriate.

[0011] Figure 1 is a schematic block diagram showing a lighting control device according to an embodiment. As shown in Figure 1, the lighting control device 10 comprises a control unit 12, a storage unit 14, an operation unit 16, a display unit 18, and a communication unit 20. The lighting control device 10 controls the lighting state of each of the multiple lighting fixtures 2 installed in television studios, stages, etc.

[0012] The multiple lighting fixtures 2 have, for example, a dimming function to change the brightness of the emitted light, a color adjustment function to change the color of the emitted light to any desired color, and a color temperature variable function to change the color temperature of the emitted light. The lighting control device 10 controls, for example, the on / off state of each of the multiple lighting fixtures 2, the brightness of the light emitted from each of the multiple lighting fixtures 2, the color of the light emitted from each of the multiple lighting fixtures 2, and the color temperature of the light emitted from each of the multiple lighting fixtures 2. The lighting control device 10 performs lighting effects in a studio or on a stage, for example, by changing the lighting state of the multiple lighting fixtures 2 according to the scene, such as a studio or a stage.

[0013] The control unit 12 controls the operation of each part of the lighting control device 10. The storage unit 14 stores programs and various data necessary for controlling the control unit 12. For example, the control unit 12 reads a program from the storage unit 14 and controls the operation of each part of the lighting control device 10 by processing the program sequentially.

[0014] The operation unit 16 is connected to the control unit 12. The operation unit 16 receives user operation instructions and inputs operation signals corresponding to the input instructions to the control unit 12. The operation unit 16 can use well-known input devices such as a mouse, keyboard, or touch panel.

[0015] The display unit 18 is connected to the control unit 12. The display unit 18 displays images on the screen corresponding to the video signal input from the control unit 12. A well-known display device such as a liquid crystal display can be used for the display unit 18. The control unit 12 displays, for example, various operation screens on the display unit 18.

[0016] The memory unit 14 stores fixture information 30 and setting information 32. The fixture information 30 is information necessary for controlling the lighting state of the lighting fixture 2. The fixture information 30 includes, for example, information representing the specifications of the lighting fixture 2.

[0017] The specifications of lighting fixture 2 vary depending on the model of lighting fixture 2. For example, lighting fixture 2 may have dimming, color temperature adjustment, and color temperature variable functions, or lighting fixture 2 may have only dimming and color temperature adjustment functions. The functions of lighting fixture 2 vary depending on the model of lighting fixture 2. Also, for example, the range of brightness that can be changed in the dimming function, the range of colors that can be changed in the color temperature adjustment function, and the range of color temperature that can be changed in the color temperature variable function vary depending on the model of lighting fixture 2. Fixture information 30 includes, for example, information on the types of functions that lighting fixture 2 has and information on the content of the functions that lighting fixture 2 has. The information on the content of the functions that lighting fixture 2 has includes, for example, information on the range of color temperatures that the corresponding lighting fixture 2 can change in the color temperature variable function.

[0018] Furthermore, the device information 30 includes, for example, information regarding the arrangement of the lighting device 2. The arrangements of the lighting devices 2 in a studio, on a stage, etc. are different for each of the plurality of lighting devices 2. By including the information regarding the arrangement of the lighting device 2 in the device information 30, for example, in the control unit 12, it becomes possible to recognize the arrangement of the corresponding lighting device 2. In other words, in the control unit 12, it becomes possible to recognize which lighting device 2 is arranged at which position in a studio, on a stage, etc.

[0019] The setting information 32 is information representing the setting of the lighting state of the lighting device 2. The setting information 32 includes, for example, information on the lighting and extinguishing of the corresponding lighting device 2, information on the brightness of the irradiated light, information on the color of the irradiated light, and information on the color temperature of the irradiated light.

[0020] Note that the information included in the device information 30 is not limited to the above, and may be any information necessary for controlling the lighting state of the lighting device 2. Also, the information included in the setting information 32 is not limited to the above, and may be any information necessary for setting the lighting state of the corresponding lighting device 2.

[0021] The device information 30 and the setting information 32 are set for each of the plurality of lighting devices 2. Although the illustration in FIG. 1 is simplified for convenience, the storage unit 14 stores a plurality of device information 30 and a plurality of setting information 32 corresponding to each of the plurality of lighting devices 2.

[0022] The communication unit 20 is connected to the control unit 12. The communication unit 20 communicates with the plurality of lighting devices 2. The control unit 12 communicates with the plurality of lighting devices 2 via the communication unit 20. The communication between the communication unit 20 and the plurality of lighting devices 2 may be wired or wireless. The communication mode between the communication unit 20 and the plurality of lighting devices 2 may be any mode capable of appropriately communicating between the communication unit 20 and the plurality of lighting devices 2.

[0023] Multiple fixture information 30 and multiple setting information 32 are stored in the storage unit 14 in advance, for example. The fixture information 30 is obtained from the lighting fixture 2 by communicating with the lighting fixture 2 via the communication unit 20, for example. The control unit 12 obtains multiple fixture information 30 corresponding to each of the multiple lighting fixtures 2 by communicating with each of the multiple lighting fixtures 2, for example, and stores the obtained multiple fixture information 30 in the storage unit 14. However, the method of obtaining the fixture information 30 is not limited to the above. The fixture information 30 may be obtained, for example, based on the operation of the operation unit 16 by the user. The method of obtaining the fixture information 30 may be any method that can appropriately obtain the fixture information 30.

[0024] The control unit 12 communicates with multiple lighting fixtures 2 via the communication unit 20 and transmits multiple setting information 32 stored in the storage unit 14 to the corresponding lighting fixtures 2, thereby turning each of the multiple lighting fixtures 2 on or off in the lighting state corresponding to the setting information 32.

[0025] The control unit 12 then allows adjustment of the contents of the multiple setting information 32. Based on the operation of the operation unit 16, the control unit 12 changes the contents of the multiple setting information 32, stores the changed setting information 32 in the storage unit 14, and transmits the changed setting information 32 to the corresponding lighting fixture 2. In this way, the control unit 12 adjusts the contents of the multiple setting information 32 based on the operation of the operation unit 16, and adjusts the lighting state of each of the multiple lighting fixtures 2 based on the adjustment of the multiple setting information 32. As a result, the control unit 12 controls the lighting state of each of the multiple lighting fixtures 2.

[0026] The lighting control device 10 does not necessarily have to communicate directly with the multiple lighting fixtures 2. The lighting control device 10 may, for example, communicate with another controller and control the lighting state of each of the multiple lighting fixtures 2 via that controller. The communication unit 20 may communicate with another controller or the like. The control unit 12 may communicate with another controller or the like via the communication unit 20 and control the lighting state of each of the multiple lighting fixtures 2 by transmitting multiple setting information 32 to the other controller or the like.

[0027] The manner in which the lighting control device 10 controls the lighting state of each of the multiple lighting fixtures 2 is not limited to the above, and may be any manner in which the lighting state of each of the multiple lighting fixtures 2 can be controlled based on multiple setting information 32.

[0028] Figure 2 is an explanatory diagram schematically showing an example of an operation screen according to the embodiment. Figure 2 schematically shows an example of an operation screen 40 used to adjust the contents of multiple setting information 32. The control unit 12 generates a video signal for the operation screen 40 based on the multiple device information 30 and multiple setting information 32 stored in the storage unit 14, and outputs the generated video signal to the display unit 18, thereby displaying the operation screen 40 on the display unit 18.

[0029] As shown in Figure 2, the operation screen 40 includes an icon display unit 42 and a setting information adjustment unit 44. The icon display unit 42 displays multiple icons 50 corresponding to each of the multiple lighting fixtures 2. The control unit 12 generates multiple icons 50 corresponding to each of the multiple lighting fixtures 2 based on, for example, multiple fixture information 30 or multiple setting information 32, and displays the generated multiple icons 50 on the icon display unit 42. Thus, the display unit 18 is a display unit for displaying the operation screen 40 which displays multiple icons 50 corresponding to each of the multiple lighting fixtures 2.

[0030] The user operates the control unit 16 and selects the desired lighting fixture 2 whose lighting state they want to adjust by selecting one of several icons 50. In this way, the control unit 12 displays several icons 50, allowing the user to select the lighting fixture 2 whose lighting state they want to adjust using the icons 50. In other words, the control unit 12 displays several icons 50, allowing the user to select the setting information 32 whose content to be adjusted using the icons 50. This makes it easy for the user to select the desired lighting fixture 2 whose lighting state they want to adjust using the controls.

[0031] Furthermore, the control unit 12 displays multiple icons 50 on the icon display unit 42 in a layout corresponding to the arrangement of multiple lighting fixtures 2, based on information regarding the arrangement of lighting fixtures 2 included in the fixture information 30. This makes it easier for the user to select the desired lighting fixture 2.

[0032] Figure 2 shows an example where five icons 50 are displayed on the icon display unit 42. The number of icons 50 displayed on the icon display unit 42 can be any number corresponding to the number of lighting fixtures 2. For example, if there are many lighting fixtures 2 installed and it is attempted to display all of the multiple icons 50 corresponding to each of the multiple lighting fixtures 2 on the icon display unit 42, the individual icons 50 may become small and difficult to see. In this case, the control unit 12 may have a function to enlarge and reduce the display of the icon display unit 42. The control unit 12 may also have a function to enlarge some of the multiple icons 50 corresponding to each of the multiple lighting fixtures 2 and display them on the icon display unit 42, or to reduce them and display all of them on the icon display unit 42.

[0033] The setting information adjustment unit 44 allows for the adjustment of the contents of multiple setting information items 32. For example, the setting information adjustment unit 44 allows for the adjustment of the contents of the setting information item 32 for lighting fixtures 2 selected by multiple icons 50. In other words, for example, the setting information adjustment unit 44 allows for the adjustment of the contents of the setting information item 32 for lighting fixtures 2 corresponding to the icon 50 selected in the icon display unit 42.

[0034] The setting information adjustment unit 44 includes, for example, a brightness adjustment unit 51 for adjusting the brightness of the light emitted from the selected lighting fixture 2, a red adjustment unit 52 for adjusting the intensity of the red light emitted from the selected lighting fixture 2, a green adjustment unit 53 for adjusting the intensity of the green light emitted from the selected lighting fixture 2, a blue adjustment unit 54 for adjusting the intensity of the blue light emitted from the selected lighting fixture 2, a white adjustment unit 55 for adjusting the intensity of the white light emitted from the selected lighting fixture 2, and a color temperature adjustment unit 56 for adjusting the color temperature of the light emitted from the selected lighting fixture 2.

[0035] Each adjustment unit 51 to 56 is a slider-type user interface that changes each value, such as brightness, between 0% and 100%. Each adjustment unit 51 to 56 displays each value in a bar graph format and also displays the numerical value of each value. However, the configuration of each adjustment unit 51 to 56 is not limited to this, and any configuration that can display the set value and allow the value to be arbitrarily adjusted in accordance with the operation of the operation unit 16 is acceptable.

[0036] The setting information adjustment unit 44 allows the brightness of the light emitted from the lighting fixture 2 to be adjusted by operating the brightness adjustment unit 51 based on the operation of the operation unit 16. The setting information adjustment unit 44 allows the color of the light emitted from the lighting fixture 2 to be adjusted by operating the red adjustment unit 52, green adjustment unit 53, blue adjustment unit 54, and white adjustment unit 55 based on the operation of the operation unit 16. Furthermore, the setting information adjustment unit 44 allows the color temperature of the light emitted from the lighting fixture 2 to be adjusted by operating the color temperature adjustment unit 56 based on the operation of the operation unit 16.

[0037] The control unit 12 has, for example, a color adjustment mode that allows arbitrary adjustment of the color of the light emitted from each lighting fixture 2, and a color temperature adjustment mode that allows arbitrary adjustment of the color temperature of the light emitted from each lighting fixture 2. When the color adjustment mode is selected, the control unit 12 adjusts the operation of the brightness adjustment unit 51, the red adjustment unit 52, the green adjustment unit 53, the blue adjustment unit 54, and the white adjustment unit 55 to ensure that light of a predetermined color is emitted from the corresponding lighting fixture 2 at a predetermined brightness. When the color temperature adjustment mode is selected, the control unit 12 adjusts the operation of the brightness adjustment unit 51 and the color temperature adjustment unit 56 to ensure that light of a predetermined color temperature is emitted from the corresponding lighting fixture 2 at a predetermined brightness. The control unit 12 can switch between the color adjustment mode and the color temperature adjustment mode, for example, by a changeover switch (not shown).

[0038] For example, when a predetermined icon 50 is selected based on an operation of the operation unit 16, the control unit 12 reads the setting information 32 of the lighting fixture 2 corresponding to the selected icon 50 from the storage unit 14, and switches the display of each adjustment unit 51 to 56 according to the read setting information 32. This allows the user to check the current lighting status of the lighting fixture 2 selected by the icon 50.

[0039] After the display on each adjustment unit 51-56 switches to the current lighting status of the selected lighting fixture 2, the user operates the operation unit 16 to adjust the values ​​of each adjustment unit 51-56, thereby arbitrarily adjusting the contents of the setting information 32. In other words, by adjusting the values ​​of each adjustment unit 51-56, the user can arbitrarily adjust the lighting status of the selected lighting fixture 2. As described above, the control unit 12 stores the modified setting information 32 in the storage unit 14 and transmits the modified setting information 32 to the corresponding lighting fixture 2. This makes it possible to control the lighting status of multiple lighting fixtures 2 via the operation screen 40.

[0040] As shown in Figure 2, the control unit 12 displays multiple icons 50 on the icon display unit 42, and based on the color temperature information contained in each of the multiple setting information 32 stored in the storage unit 14, displays the numerical value of the color temperature of the light emitted from each of the multiple lighting fixtures 2 (a string representing the color temperature) within the corresponding multiple icons 50. For example, the control unit 12 overlays the numerical color temperature within the icon 50.

[0041] The control unit 12 may, for example, display a numerical value for the color temperature within the icon 50 when the color temperature adjustment mode is selected. The control unit 12 may also, for example, display a numerical value representing the color of the irradiated light (for example, numerical values ​​for the intensity of red light, green light, blue light, and white light) within the icon 50 when the color adjustment mode is selected.

[0042] For example, in lighting effects for plays and dramas, when trying to represent natural light, such as sunrise being 2000K, daytime sunlight being 5000K, and moonlight being 4000K, the color temperature of the light emitted from multiple lighting fixtures is adjusted.

[0043] In this embodiment, the lighting control device 10 displays the color temperature values ​​of the light emitted from each of the multiple lighting fixtures 2 within the corresponding icons 50, as described above. This makes it easier for the user to understand the current color temperature setting when, for example, operating the operation unit 16 to adjust the color temperature of the light emitted from the lighting fixtures 2. In other words, it makes it easier to check the current color temperature setting when adjusting the color temperature.

[0044] Furthermore, the lighting control device 10 can also perform lighting effects by pre-saving lighting effect data for predetermined scenes, such as studios or stages, as scene data, and then playing back the saved scene data. When generating such scene data, the current color temperature setting can be easily confirmed by displaying the color temperature value within the icon 50. When generating scene data, the control unit 12 only stores the modified setting information 32 in the storage unit 14 and does not transmit the modified setting information 32 to the corresponding lighting fixture 2. Thus, the control unit 12 does not necessarily have to transmit the modified setting information 32 to the corresponding lighting fixture 2 at the same time as adjusting the contents of the setting information 32 by each adjustment unit 51 to 56.

[0045] For example, as mentioned above, the range of color temperatures that can be changed in the color temperature variable function may differ depending on the model of the lighting fixture 2. Therefore, even if the color temperature adjustment unit 56 is set to the same 50%, the resulting color temperature may differ depending on the model of the lighting fixture 2.

[0046] The control unit 12 determines the set color temperature based on the operation of the operation unit 16 and the color temperature range information included in the fixture information 30, for example, when the operation of the operation unit 16 is performed to change the color temperature setting of a predetermined lighting fixture 2. For example, if the color temperature adjustment unit 56 is set to 50% in a lighting fixture 2 with a color temperature range of 2000K to 5000K, the control unit 12 determines that the set color temperature is 3500K. Also, if the color temperature adjustment unit 56 is set to 50% in a lighting fixture 2 with a color temperature range of 3000K to 8000K, the control unit 12 determines that the set color temperature is 5500K.

[0047] The control unit 12 stores the determined color temperature as modified setting information 32 in the storage unit 14, and displays the color temperature value within the corresponding icon 50 based on the setting information 32. This allows the appropriate color temperature value to be displayed within the icon 50 even when the models of multiple lighting fixtures 2 are different. Even when the models of multiple lighting fixtures 2 are different, it is easier to adjust to the desired color temperature by referring to the color temperature value displayed within the icon 50.

[0048] Thus, the lighting control device 10 according to this embodiment can display the lighting status settings (color temperature settings) of multiple lighting fixtures 2 in a more understandable way.

[0049] In the above embodiment, the color temperature of the light emitted from multiple lighting fixtures 2 can be adjusted. However, depending on the connected lighting fixtures 2, some lighting fixtures 2 may not have a color temperature adjustment function. Therefore, the lighting control device 10 does not necessarily have to be able to adjust the color temperature of the lighting fixtures 2. The setting information adjustment unit 44 does not necessarily have to have a color temperature adjustment unit 56. For example, to make it easy to check the color temperature of the connected lighting fixtures 2, the color temperature value may be displayed within the icon 50.

[0050] In the above embodiment, the lighting state of each of the multiple lighting fixtures 2 can be controlled via the setting information adjustment unit 44. For example, the operation unit 16 may be provided with multiple operating members (e.g., feeders) corresponding to each of the multiple lighting fixtures 2, so that the lighting state of each of the multiple lighting fixtures 2 can be controlled in accordance with the operation of the multiple operating members of the operation unit 16. The operation screen 40 does not necessarily have a setting information adjustment unit 44. For example, the color temperature value displayed in the icon 50 may change in conjunction with the operation of the multiple operating members of the operation unit 16.

[0051] Figure 3 is an explanatory diagram schematically showing a modified example of the operation screen according to the embodiment. For components that are substantially the same in function and configuration as those in the above embodiments, the same reference numerals are used, and detailed explanations are omitted.

[0052] As shown in Figure 3, in this example, the control unit 12 displays a plurality of icons 50 on the icon display unit 42, and based on the color temperature information contained in each of the plurality of setting information 32 stored in the storage unit 14, displays the numerical value of the color temperature of the light emitted from each of the plurality of lighting fixtures 2 within the corresponding plurality of icons 50, and also displays each of the corresponding plurality of icons 50 in a color corresponding to the color temperature of the light emitted from each of the plurality of lighting fixtures 2.

[0053] The control unit 12, for example, displays the color temperature value within the icon 50 when the color temperature adjustment mode is selected, and also displays the icon 50 in a color corresponding to the color temperature. The control unit 12 may also display the icon 50 in a color corresponding to the color of the irradiated light when the color adjustment mode is selected.

[0054] In this way, the control unit 12 displays the color temperature value within the icon 50 and displays the icon 50 in a color corresponding to the color temperature. This makes the current color temperature setting easier for the user to understand. It allows the user to grasp the current color temperature setting more intuitively.

[0055] In this example, the control unit 12 displays the color temperature adjustment unit 56 in a color corresponding to the color temperature. For example, the control unit 12 displays the set portion of the slider-shaped color temperature adjustment unit 56 in a color corresponding to the color temperature. More specifically, the set portion is the range from 0% to 70% when the color temperature is set to 70%. This makes the current color temperature setting easier for the user to understand.

[0056] Furthermore, in this example, the control unit 12 displays the color temperature value on the color temperature adjustment unit 56. This makes the current color temperature setting easier for the user to understand compared to, for example, when the color temperature setting is expressed as a percentage.

[0057] Figures 4(a) to 4(f) are schematic explanatory diagrams illustrating modified examples of the icons according to the embodiment. As shown in Figure 4(a), the control unit 12 may further display a brightness indicator 60, which represents the brightness of the light emitted from the corresponding lighting fixture 2, on the icon 50. For example, the control unit 12 displays a brightness indicator 60, which represents the brightness of the light emitted from each of the multiple lighting fixtures 2, on each of the corresponding multiple icons 50, based on the brightness information contained in each of the multiple setting information 32. For example, the control unit 12 displays the brightness indicator 60 overlaid within the icon 50. By displaying the brightness indicator 60 on the icon 50 in this way, the current brightness setting and color temperature setting can be displayed to the user in a more understandable manner.

[0058] The brightness display unit 60 is, for example, a bar graph-shaped meter that changes between 0% and 100%. However, the form of the brightness display unit 60 is not limited to this. The brightness display unit 60 may also be, for example, a pie chart-shaped meter. The form of the brightness display unit 60 may be any form that can appropriately display the set brightness.

[0059] As shown in Figure 4(b), the brightness indicator 60 does not necessarily have to be displayed so as to fit within the icon 50. Also, as shown in Figure 4(c), the brightness indicator 60 may be displayed adjacent to the icon 50. The display mode of the brightness indicator 60 can be any mode that allows the brightness indicator 60 to be recognized as being related to the icon 50.

[0060] As shown in Figure 4(d), the control unit 12 may further display a numerical value representing the brightness of the light emitted from the corresponding lighting fixture 2 on the icon 50. For example, the control unit 12 displays a numerical value representing the brightness of the light emitted from each of the multiple lighting fixtures 2 on each of the corresponding multiple icons 50, based on the brightness information contained in each of the multiple setting information 32. For example, the control unit 12 displays the numerical value representing brightness as a percentage based on the operation of the brightness adjustment unit 51.

[0061] As shown in Figure 4(e), the control unit 12 may further display a brightness indicator 60 representing the brightness of the light emitted from the corresponding lighting fixture 2, and a numerical value representing the brightness of the light emitted from the corresponding lighting fixture 2, on an icon 50.

[0062] As shown in Figure 4(f), the control unit 12 may, for example, represent the brightness using a gradation of 256 levels. The numerical value representing brightness can be any value that appropriately represents the brightness of the light emitted from the corresponding lighting fixture 2.

[0063] This embodiment includes the following aspects. (Note 1) A lighting control device that controls the lighting state of each of multiple lighting fixtures, An operating unit for inputting operation instructions, A display unit for displaying an operation screen showing multiple icons corresponding to each of the multiple lighting fixtures, A storage unit that stores multiple setting information corresponding to each of the aforementioned multiple lighting fixtures, A control unit that adjusts the contents of the plurality of setting information based on the operation of the operation unit, and controls the lighting state of each of the plurality of lighting fixtures based on the adjustment of the plurality of setting information, Equipped with, Each of the aforementioned multiple setting information is information representing the lighting state setting of each of the aforementioned multiple lighting fixtures, and includes information on the color temperature of the light emitted from the corresponding lighting fixture. The control unit is a lighting control device that displays the color temperature values ​​of the light emitted from each of the multiple lighting fixtures within the corresponding multiple icons, based on the color temperature information contained in each of the multiple setting information stored in the storage unit.
