DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. Note that the embodiments described below are all comprehensive or specific examples. The numerical values, shapes, materials, components, component arrangement and connection forms, steps, and order of steps shown in the following embodiments are merely examples and are not intended to limit the present invention. In addition, among the components in the following embodiments, components that are not described in the independent claims will be described as optional components.

[0012] In addition, each drawing is a schematic diagram and is not necessarily a precise illustration. In each drawing, the same reference numerals are used for substantially the same configurations, and duplicated explanations may be omitted or simplified.

[0013] (Embodiment) [composition] First, a configuration of a lighting control system according to an embodiment will be described below. Fig. 1 is a block diagram showing a functional configuration of a lighting control system according to an embodiment.

[0014] The lighting control system 10 is a system that controls lighting devices 20 for production installed on a stage, a television studio, or the like. The lighting control system 10 is used for lighting production in plays, concert events, television program recordings, and the like. As shown in Fig. 1, the lighting control system 10 includes a plurality of lighting devices 20 and a dimmer console 30. The number of lighting devices 20 included in the lighting control system 10 is not particularly limited, and the lighting control system 10 only needs to include at least one lighting device 20.

[0015] The lighting device 20 is a lighting device for stage effects, specifically a spotlight or a moving light. The lighting device 20 is capable of changing the dimming level and the emitted light color. The lighting device 20 includes a light-emitting element that emits red light, a light-emitting element that emits blue light, and a light-emitting element that emits green light, and the emitted light color is changed, for example, by independently controlling the brightness of these light-emitting elements. The light-emitting elements are, for example, LED (Light Emitting Diode) elements, but may also be realized by organic EL (Electro-Luminescence) elements or the like.

[0016] The dimmer desk 30 is an example of a lighting control device, and receives a user operation for controlling the lighting device 20 from a user, and controls the lighting device 20 based on the received operation. The dimmer desk 30 includes a user interface (UI) unit 31, a plurality of sub-master faders 32, a control unit 33, and a storage unit 34.

[0017] The user interface unit 31 receives operations from a user for setting a lighting scene (at least one of the dimming level and the emission color of the lighting device 20) to the sub-master fader 32. The user interface unit 31 is realized by, for example, a display on which an image is displayed, a touch panel, hardware keys, a fader, and the like.

[0018] The sub-master fader 32 is a fader operated by a user to play back a lighting scene set in the sub-master fader 32. One sub-master fader 32 is provided with one knob (operated unit). In other words, the knob is a knob. The sub-master fader 32 is, for example, a physical fader, but may also be a virtual fader realized by a GUI (Graphical User Interface) or the like.

[0019] The control unit 33 controls the lighting device 20 in response to a user's operation on the sub-master fader 32 (raising and lowering the knob of the sub-master fader 32). The control unit 33 controls parameters of the lighting device 20, for example, by transmitting a control signal to the lighting device 20. The parameters of the lighting device 20 include a parameter indicating the brightness of the lighting device 20 (also referred to as a dimming level) and a parameter indicating the emission color of the lighting device 20 (hereinafter simply referred to as an emission color). The functions of the control unit 33 are realized, for example, by a microcomputer or processor constituting the control unit 33 executing a computer program stored in the storage unit 34.

[0020] The storage unit 34 is a storage device that stores the computer programs and various information (setting information for lighting scenes) necessary for controlling the lighting device 20. The storage unit 34 is realized by, for example, a semiconductor memory.

[0021] [Dimming level control] First, an example in which the dimming level of the lighting device 20 is controlled based on an operation on the sub-master fader 32 will be described. Fig. 2 is a diagram showing an example of setting dimming levels for a plurality of sub-master faders 32. Figs. 3 to 5 are diagrams for explaining the relationship between the knob positions of the plurality of sub-master faders 32 and the dimming levels. In the following description using Figs. 2 to 5, the two sub-master faders 32 are distinguished as sub-master fader 1 and sub-master fader 2, and the two lighting devices 20 are distinguished as lighting device 20a and lighting device 20b.

[0022] In the example of Fig. 2, the sub-master fader 1 is set to a dimming level of 100% (maximum light emission state) for the lighting device 20a, and a dimming level of 0% (off state) for the lighting device 20b. The sub-master fader 2 is set to a dimming level of 50% for the lighting device 20a, and a dimming level of 50% for the lighting device 20b. The settings as shown in Fig. 2 are stored in the storage unit 34 as setting information, and are referred to by the control unit 33. Although not shown in Fig. 2 for the sake of simplicity, the sub-master fader 32 can be set with a light emission color (a combination of RGB dimming levels, described later) in addition to a dimming level.

[0023] In this state, the knob of the submaster fader 1 is raised to the top as shown in Figure 3. When the submaster fader 1 knob is raised to the center, the control unit 33 sets the dimming level of the lighting device 20a to 100% and the dimming level of the lighting device 20b to 0%. In other words, the control unit 33 causes the lighting device 20a to emit light at a dimming level of 100% and the lighting device 20b to not emit light. When the knob of the submaster fader 1 is raised to the center, the control unit 33 sets the dimming level of the lighting device 20a to 50% and the dimming level of the lighting device 20b to 0%.

[0024] 4, when the knob of the submaster fader 2 is raised to the top, the control unit 33 sets the dimming level of the lighting device 20a to 50%, and the dimming level of the lighting device 20b to 50%. In other words, the control unit 33 causes the lighting device 20a to emit light at a dimming level of 50%, and the lighting device 20b to emit light at a dimming level of 50%. Note that when the knob of the submaster fader 2 is raised to the center, the control unit 33 sets the dimming level of the lighting device 20a to 25%, and the dimming level of the lighting device 20b to 25%.

[0025] 5, when both the knobs of submaster fader 1 and submaster fader 2 are raised to the top, the higher dimming level is given priority between the dimming level determined by the position of the knob of submaster fader 1 and the dimming level determined by the position of the knob of submaster fader 2. Therefore, control unit 33 sets the dimming level of lighting device 20a to 100% and the dimming level of lighting device 20b to 50%.

[0026] Although not shown, when both the knobs of submaster fader 1 and submaster fader 2 are raised to the center, control unit 33 sets the dimming level of lighting device 20a to 50% and the dimming level of lighting device 20b to 25%.

[0027] In this way, the control unit 33 controls the dimming level of the lighting device 20b to the highest dimming level among the multiple dimming levels indicated by the knob positions of the multiple sub-master faders 32. For controlling the dimming level, HTP (Highest Takes Precedence) control is adopted, in which the highest dimming level has priority. Parameters for which HTP control is adopted, such as the dimming level, are also referred to as second parameters or HTP parameters.

[0028] [Emitting color control] Next, an example in which the emission color of the lighting device 20 is controlled based on an operation on the sub-master fader 32 will be described. Fig. 6 is a diagram showing an example of setting emission colors to a plurality of sub-master faders 32. Although not shown in Fig. 6 for the sake of simplicity, the sub-master fader 32 can set a dimming level in addition to the emission color. Also, Fig. 6 shows an example in which the emission color of one lighting device 20 is set to one sub-master fader 32, it is also possible to set emission colors of a plurality of lighting devices 20 to one sub-master fader 32.

[0029] 6, the emitted light color is determined by a combination of, for example, the dimming level of a light-emitting element emitting red light, the dimming level of a light-emitting element emitting green light, and the dimming level of a light-emitting element emitting blue light. Hereinafter, the dimming level of a light-emitting element emitting red light is described as R: 0% to 100%, the dimming level of a light-emitting element emitting green light is described as G: 0% to 100%, and the dimming level of a light-emitting element emitting blue light is described as B: 0% to 100%.

[0030] In the example of Fig. 6, sub-master fader 1 is set with (R: 100%, G: 0%, B: 0%) as the emission color for lighting device 20. Similarly, sub-master fader 2 is set with (R: 0%, G: 100%, B: 0%) as the emission color for lighting device 20, and sub-master fader 3 is set with (R: 0%, G: 0%, B: 100%) as the emission color for lighting device 20. Settings such as those in Fig. 6 are stored in storage unit 34 as setting information and are referred to by control unit 33.

[0031] In this case, when only the knob of submaster fader 1 is raised from the bottom to the top without raising the knobs of submaster fader 2 and submaster fader 3, the control unit 33 changes the light color of the lighting device 20 from R: 0% to R: 100% according to the position of the knob. Similarly, when only the knob of submaster fader 2 is raised from the bottom to the top, the control unit 33 changes the light color of the lighting device 20 from G: 0% to G: 100% according to the position of the knob. When only the knob of submaster fader 3 is raised from the bottom to the top, the control unit 33 changes the light color of the lighting device 20 from B: 0% to B: 100% according to the position of the knob.

[0032] FIG. 7 is a diagram for explaining the change in the emission color of the lighting device 20 when the knobs of the sub-master faders 1 to 3 are raised in order.

[0033] 7, first the knob of the submaster fader 1 is raised to the top. As described above, when the knob of the submaster fader 1 reaches the top, the lighting device 20 emits light at R:100%.

[0034] Next, when the sub-master fader 2 is raised from the bottom to the top in this state, the light emission color of the lighting device 20 changes from R:100% to G:100% according to the position of the knob. Specifically, when the sub-master fader 2 is raised from the bottom to the top, the control unit 33 changes from R:100% to R:0% and from G:0% to G:100% in parallel. In this way, in controlling the light emission color, the light emission color of the sub-master fader 2 operated last is given priority.

[0035] Similarly, when the knob of the submaster fader 2 has reached the top and the submaster fader 3 is raised from the bottom to the top, the light emission color of the lighting device 20 changes from G:100% to B:100% according to the knob position. In other words, the light emission color of the submaster fader 3 operated last takes priority.

[0036] In this way, the control of the emitted color employs LTP (Latest Takes Precedence) control, in which the most recent emitted color takes precedence. Note that parameters other than the emitted color for which LTP control is employed include the direction in which the lighting device 20 emits light (such as the pan angle and the tilt angle). In the case where the lighting device 20 is a strobe lighting device, another parameter for which LTP control is employed is the strobe frequency. Such parameters for which LTP control is employed are also referred to as first parameters or LTP parameters.

[0037] [Sequence Control] The lighting control system 10 is capable of not only controlling the dimming level and the luminous color based on the user's manual operation of the sub-master fader 32, but also of sequence control for playing one or more predetermined lighting scenes in a desired order. Figure 8 is a time chart of sequence control.

[0038] For example, the user generates lighting scenes 1, 2, and 3 by operating the user interface unit 31 or the like. The lighting scenes 1 to 3 are configured by the set values ​​of the dimming level and the set values ​​of the emitted light color. For example, the dimming level of 80%, R: 100%, G: 0%, and B: 0% is set in the lighting scene 1, the dimming level of 90%, R: 0%, G: 100%, and B: 0% is set in the lighting scene 2, and the dimming level of 100%, R: 0%, G: 0%, and B: 100% is set in the lighting scene 3. The contents of the generated lighting scenes (the set values ​​of the dimming level and the emitted light color) are stored in the storage unit 34 as scene information and are referred to by the control unit 33.

[0039] The user further generates sequence information by setting the playback times and transition times of the lighting scenes 1 to 3 through operations on the user interface unit 31. The generated sequence information is stored in the storage unit .

[0040] When a user performs a predetermined operation on the user interface unit 31 to start sequence control, the control unit 33 executes sequence control based on the sequence information and scene information stored in the storage unit 34. In this way, the lighting control system 10 is capable of sequence control.

[0041] [Change in illumination color when the submaster fader is lowered] Incidentally, as shown in FIG. 7 above, when the knobs of submaster faders 1 to 3 are sequentially raised to the top and then the knob of submaster fader 3 is lowered, there are two possible control methods for controlling the emitted color.

[0042] The first control method is a method of changing the luminous color of the submaster fader 2 that was raised immediately before the submaster fader 3. That is, when the knob of the submaster fader 3 is lowered from the top to the bottom, the luminous color of the lighting device 20 changes from B: 100% to G: 100% according to the position of the knob. Specifically, during the period in which the knob of the submaster fader 3 is lowered from the top to the bottom, the control unit 33 changes from B: 100% to B: 0% and from G: 0% to G: 100% in parallel. As a result, the luminous color of the lighting device 20 smoothly transitions (fades) according to the position of the knob of the submaster fader 32 and the degree of reproduction of the sequence control. The dimming level of the lighting device 20 is changed according to the above-mentioned HTP control.

[0043] Such a first control method is useful when performing the above-mentioned sequence control, by raising the submaster fader 32 to change the light emission color in a spot manner, and then lowering the submaster fader 32 to return to sequence control. More specifically, it is useful when it is desired to change the light emission color only when a certain person appears on a stage under a certain lighting condition (during sequence control), and then return to the original lighting condition (sequence control) after a while. Note that the first control method is applied when the submaster fader 32 is lowered without being raised to the top (for example, when it is raised to 80% and then lowered).

[0044] The second control method is a method for maintaining the luminous color (B: 100%) of the submaster fader 3 even when the knob of the submaster fader 3 is lowered. In this case, the luminous color is maintained, while the dimming level of the lighting device 20 is changed according to the above-mentioned HTP control.

[0045] In the first control method, the user needs to remember the sequence of operations of the submaster faders 32, but in the second control method, this is not necessary.

[0046] In addition, in the first control method, when only one knob of the submaster fader 32 reaches the top, lowering the knob may cause an unintended change in the emission color of the lighting device 20. For example, a combination of a change in the dimming level and a change in the emission color may cause the emission color to rapidly change exponentially toward the default black or white. When the submaster fader 32 is set to the direction in which the lighting device 20 emits light, the lighting device 20 may face directly downward, and when the submaster fader 32 is set to a strobe frequency, the lighting device 20 may transition to an unintended strobe frequency. In contrast, in the second control method, such unintended changes in the LTP parameters do not occur.

[0047] [Control switching behavior] The first and second control methods each have advantages and disadvantages. Therefore, the lighting control system 10 performs an operation of adaptively switching between the first and second control methods. Fig. 9 is a flowchart of the control switching operation of the lighting control system 10. At the start of the flowchart in Fig. 9, the knob of the sub-master fader 32 has reached the top.

[0048] When the control unit 33 detects an operation of lowering the knob of the sub-master fader 32 located at the top (S11), it determines whether or not sequence control is being executed (S12). Whether or not sequence control is being executed is determined, for example, by referring to an execution flag for sequence control stored in the storage unit 34, but may be determined by other methods.

[0049] When the control unit 33 determines that the sequence control is being executed (Yes in S12), it performs control such that the light emission color of the lighting device 20 approaches the light emission color determined by the sequence control as the knob of the sub-master fader 32 is lowered (S13), similarly to the first control method described above. For example, when a lighting scene set to R: 100% in the sequence control is executed and the sub-master fader 32 is set to B: 100%, the light emission color of the lighting device 20 changes from B: 100% to R: 100% according to the position of the knob. Specifically, during the period in which the knob of the sub-master fader 32 is lowered from the top to the bottom, the control unit 33 changes from B: 100% to B: 0% and from R: 0% to R: 100% in parallel. As a result, the light emission color of the lighting device 20 smoothly transitions (fades) according to the position of the knob of the sub-master fader 32 and the degree of playback of the sequence control.

[0050] When sequence control is being executed, if the knob of the sub-master fader 32 is raised while being lowered from the top, the emission color of the lighting device 20 approaches the state when it is raised to the top.

[0051] On the other hand, when the control unit 33 determines that sequence control is not being executed (No in S12), it does not change the emitted color even if the knob of the sub-master fader 32 is turned down (S14), as in the second control method described above.

[0052] In this way, the lighting control system 10 can flexibly control the emitted light color by switching between the first control method and the second control method depending on whether or not sequence control is being executed.

[0053] 9 can also be applied to other LTP parameters (such as the direction in which the lighting device 20 emits light, the strobe frequency, etc.) In other words, in the description of FIG. 9 above, "emission color" may be read as "LTP parameter."

[0054] [Effects, etc.] As described above, the lighting control system 10 includes the control unit 33 that controls the parameters of the lighting device 20 in response to a user's operation on the submaster fader 32. When sequence control is being performed on the lighting device 20 to play one or more predetermined lighting scenes, the control unit 33 brings the above parameters closer to values ​​determined in the sequence control as the submaster fader 32 decreases, and when sequence control is not being performed on the lighting device 20, the control unit 33 does not change the values ​​of the above parameters even if the submaster fader 32 decreases.

[0055] Such a lighting control system 10 can flexibly control the parameters of the lighting device 20.

[0056] Moreover, for example, the above parameters indicate the emission color of the lighting device 20.

[0057] Such a lighting control system 10 can flexibly control the emission color of the lighting device 20.

[0058] Furthermore, for example, the above parameters indicate the direction in which the lighting device 20 emits light.

[0059] Such a lighting control system 10 can flexibly control the direction in which the lighting device 20 emits light.

[0060] Also, for example, the control unit 33 controls a first parameter, which is the above-mentioned parameter, and a second parameter of the lighting device 20 that is different from the above-mentioned parameter, in response to user operation of the multiple sub-master faders 32, and controls the second parameter to the largest value among multiple values ​​indicated by the positions of the multiple sub-master faders 32.

[0061] Such a lighting control system 10 can control the first parameter and the second parameter in response to user operations on the multiple sub-master faders 32.

[0062] Furthermore, for example, the second parameter indicates the brightness of the light emitted by the lighting device 20.

[0063] Such a lighting control system 10 can control the brightness of the light emitted by the lighting device 20 in response to a user's operation on the sub-master fader 32.

[0064] For example, the lighting control system 10 further includes a lighting device 20.

[0065] In this manner, the lighting control system 10 may be realized as a system including the lighting device 20.

[0066] The dimmer desk 30 also includes a control unit 33 that controls parameters of the lighting device 20 in response to a user's operation on the sub-master fader 32. When sequence control is being performed on the lighting device 20 to play one or more predetermined lighting scenes, the control unit 33 brings the above parameters closer to values ​​determined in the sequence control as the sub-master fader 32 decreases, and when sequence control is not being performed on the lighting device 20, the control unit 33 does not change the above parameters even if the sub-master fader 32 decreases. The dimmer desk 30 is an example of a lighting control device.

[0067] Such a dimmer console 30 can flexibly control the parameters of the lighting device 20.

[0068] Furthermore, the lighting control method executed by a computer such as the control unit 33 is a lighting control method that controls parameters of the lighting device 20 in response to a user's operation on the submaster fader 32. When sequence control is performed on the lighting device 20 to play one or more predetermined lighting scenes, the lighting control method brings the above parameters closer to values ​​determined in the sequence control as the submaster fader 32 decreases, and when sequence control is not being performed on the lighting device 20, the above parameters are not changed even if the submaster fader 32 decreases.

[0069] Such a lighting control method allows for flexible control of the parameters of the lighting device 20.
