However, even if the predetermined color temperature is the same for a plurality of lighting fixtures, the actual color temperature may differ due to individual differences between the lighting fixtures. Moreover, even if the initial colors are uniformed by fine adjustment in advance, the actual color temperature difference between the lighting fixtures may occur due to the light change.

This is especially true when using multiple luminaires from different manufacturers. Therefore, even if a plurality of lighting fixtures having the same color temperature are used, it is difficult to achieve an environment with a uniform color tone as a whole.

In order to solve this problem, the lighting operator can determine the color temperature of each of the multiple lighting fixtures by directly visually judging the emitted color of the lighting or by indirectly judging by camera images. There is a means to manually adjust several parameters for setting However, with this method, it is difficult and time consuming to precisely adjust a plurality of parameters for lighting fixtures composed of a plurality of types.

In order to solve this manual adjustment problem, a lighting control device has been proposed that remotely controls a plurality of lighting fixtures and automatically controls the emission color of each lighting fixture (see, for example, Patent Document 1). This makes it possible to set the emission colors of the plurality of lights to the same color temperature as the ambient light, which is the current natural light.

This lighting control device sets the RGB values of the measured ambient light as reference values RGB_S. Then, for each of the plurality of lighting fixtures, the lighting control device calculates a manipulated variable by controlling the difference between the RGB value of the fixture light of the lighting fixture and the reference value RGB_S to be 0, and performs this operation. It emits light with an instrument light according to the amount.

Light characteristic measurement processing, fixture light change processing, and the like are executed, and the luminous colors of the lighting fixtures 4-1, 4-2, . . . are finely adjusted manually.

The lighting operator OP installs the ambient light measuring device 2-0 at a place to be illuminated, and operates a switch or the like at a place different from the place to be illuminated, so as to cause the lighting control device 1 to execute processing. can be

(hereinafter referred to as measurement result of the fixture light) is transmitted to the lighting control device 1; Further, the ambient light measuring devices 2-0 and 2-1 measure the color of the ambient light and transmit the measurement result of the ambient light color (hereinafter referred to as the ambient light measurement result) to the lighting control device 1. FIG.

Here, the lighting fixture 4-1 to which the ambient light measuring device 2-1 is attached is used as a reference lighting fixture. Both the lighting processing device 3-1 and the ambient light measuring device 2-1 measure the color of light emitted from the lighting fixture 4-1. It can have two roles. That is, each of the lighting processing device 3-1 and the ambient light measuring device 2-1 can measure the color of the light emitted from the lighting device 4-1 and the color of the ambient light.

The lighting control device 1 is, for example, a tablet-type operation terminal, and is a device that controls the emission colors of the lighting fixtures 4-1, 4-2, .

[Outline of the present invention]
Next, an outline of the present invention will be described. The present invention shows the relationship between the lighting fixture 4-1 and the lighting fixture 4-2, which are the reference lighting fixtures shown in FIG. The focus is on the fact that it can be represented by a characteristic (slope of linear change). In the present invention, for example, when the operation amount of the lighting device 4-1 is changed, the measurement result of the device light of the lighting device 4-1 follows the measurement result of the device light of the lighting device 4-2.

Here, by the method described in the above-mentioned Patent Document 1, the difference between the color of the ambient light and the measurement result of the device light of the lighting devices 4-1, 4-2, . It is assumed that an environment with a uniform hue as a whole is realized in correspondence with the ambient light.

RB is the _R value, GB is the G value, and GB is the _G value of the reference value (requested light color of the ambient light, here, for example, RGB values. Hereinafter, RGB will be described as the required light color.), which is the result of measuring the ambient light. Let the B value be B _B and be expressed as (R _0(B) , G _0(B) , B _0(B) ).

Further, the RGB values of the measurement result of the device light of the lighting device 4-1 are (R ₁ , G ₁ , B ₁ ), and the RGB values of the measurement result of the device light of the lighting device 4-2 are (R ₂ , G ₂ , B ₂ ), .

When the color of the ambient light matches the color of the light from the lighting _{fixtures 4-1 , 4-2} , . _(B) = G ₁ = G ₂ = . . . B _{0 (B)} = B ₁ = B ₂ = . , which corresponds to the ambient light.

In this state, regarding the lighting fixture 4-1, when the manipulated variable of only the R component among the RGB components is changed to the manipulated variable +α, the RGB value, which is the measurement result of the fixture light, is expressed as (R _{1(B+α )} , G _1(B) , B _1(B) ). The original operation amount in this case is the operation amount when the color of the instrument light matches the color of the ambient light, and α, which is a predetermined amount, is added to the operation amount.

Further, regarding the lighting device 4-1, the RGB values when the operation amount of only the G component is changed to the operation amount +α are (R _1(B) , G _1(B+α) , B _1(B) ), Let (R1 _(B) , G1 _(B) , B1 _(B+α) ) be the RGB values when the manipulated variable for only the B component is changed to the manipulated variable +α.

Similarly, for the lighting fixture 4-2, the RGB value, which is the measurement result of the fixture light when the manipulated variable of only the R component is changed to the manipulated variable +α, is (R _2(B+α) , G _2(B) , B _2(B) ). Further, regarding the lighting fixture 4-2, let the RGB values when the manipulated variable of only the G component is changed to the manipulated variable +α be (R _2(B) , G _2(B+α) , B _2(B) ), Let (R _{2 (B)} , G _{2 (B)} , B _{2 (B+α)} ) be the RGB values when the manipulated variable of only the B component is changed to the manipulated variable +α.

FIG. 2 is a diagram showing characteristics a and b representing the relationship between the manipulated variable of the R component of the instrument light and the R value of the instrument light. The horizontal axis indicates the manipulated variable (%) of the R component, and the vertical axis indicates the R value of the instrument light (the R value of the measurement result of the instrument light). a indicates the R value characteristic of the lighting fixture 4-1, and b indicates the R value characteristic of the lighting fixture 4-2.

Further, in the characteristic a of the R value of the lighting fixture 4-1, R ₁₍₄₀₎ is the R value of the fixture light when the manipulated variable of the R component is 40%, and R ₁₍₆₀₎ is the R component is the R value of the instrument light when the operation amount of is 60%. Further, in the characteristic b of the R value of the lighting fixture 4-2, R ₂₍₄₀₎ is the R value of the fixture light when the manipulated variable of the R component is 40%, and R ₂₍₆₀₎ is the R component is the R value of the instrument light when the operation amount of is 60%.

From FIG. 2, the slope of the R value characteristic a of the lighting fixture 4-1 (the slope of the R value of the fixture light with respect to the manipulated variable of the R component) is compared with the slope of the R value characteristic b of the lighting fixture 4-2. Then, it can be seen that the latter is larger than the former in the region where the manipulated variable is greater than 20%. In other words, when the manipulated variable of the R component is changed by the same amount in the lighting fixtures 4-1 and 4-2, the amount of change in the R value of the fixture light is greater in the lighting fixture 4-2 than in the lighting fixture 4-1. bigger than

Here, in a state where the R values of the fixture lights of the lighting fixtures 4-1 and 4-2 are the same, and an environment with a uniform color tone is realized as a whole corresponding to the ambient light, the lighting fixture 4-1 Assume that the operation amount of the lighting fixture 4-1 is changed to the operation amount +α in order to change the setting of the color of the light from the lighting fixture 4-1 to a predetermined color.

In this case, the lighting fixture 4-1 is changed to a predetermined color corresponding to the operation amount +α, but as for the lighting fixture 4-2, even if the operation amount is changed to the operation amount +α, the lighting fixture 4-1 It does not become the same predetermined color as 1. This is because the lighting fixtures 4-1 and 4-2 have individual differences, and the slopes of the characteristics of the lighting fixtures 4-1 and 4-2 are different as shown in FIG.

Therefore, in the embodiment of the present invention, when the lighting device 4-1 is changed to a predetermined color corresponding to the operation amount +α, the lighting device 4-2 is also changed to the same predetermined color. Output the manipulated variable +α'.

FIG. 3(1) is a diagram for explaining the relationship between the R value characteristics a and b of the instrument light. The R values of the lighting fixtures 4-1 and 4-2 are the same (R _1(B) =R _2(B) ), and an environment with a uniform hue as a whole corresponding to the ambient light is realized. assume. The amounts of operation of the lighting fixtures 4-1 and 4-2 in this case are assumed to be SR ₁ and SR ₂ respectively.

Then, when the operation amount SR ₁ of the lighting fixture 4-1 is changed to the operation amount SR ₁ +α, the R value changes from R _1(B) to R _1(B+α) , and the lighting fixture 4-2 is changed to SR ₂ +α, the R value changes from R _{2 (B)} to R _2(B+α) . Since the lighting fixtures 4-1 and 4-2 have individual differences, R _1(B+α) <R _2(B+α) in the characteristics a and b.

Here, using R 1(B _+α) as a reference value so that the difference between R _1(B+α) and R _2(B+α) becomes 0, the operation amount of the lighting fixture 4-2 is Let SR ₂ +α be changed in the direction of arrow y.

FIG. 3(2) is a diagram for explaining the parameter x _R1 and FIG. 3(3) is a diagram for explaining the parameter x _R2 .

As shown in FIG. 3(2), when the manipulated variable in the characteristic b of the R value of the lighting fixture 4-2 is changed to the manipulated variable +1 (%), the change in the apparent R value is the same as that of the lighting fixture 4-2. The amount of change in the manipulated variable of the lighting fixture 4-1 to cause the characteristic a of the R value of −1 is assumed to be a parameter x _R1 .

Further, as shown in FIG. 3(3), when the operation amount in the R value characteristic a of the lighting fixture 4-1 is changed to the operation amount +1 (%), the change in the apparently same R value is The amount of change in the manipulated variable of the lighting fixture 4-2 to cause the characteristic b of the R value of the lighting fixture 4-2 is defined as a parameter x _R2 .

In general, LED lamp bodies such as lighting fixtures 4-1 and 4-2 are designed with the goal of linearly changing the fixture light, and as shown in FIG. % is stable.

Therefore, the relationship between the R value characteristic a of the lighting fixture 4-1 and the R value characteristic b of the lighting fixture 4-2 is as follows when the manipulated variable is 20<B<B+α(%): is represented by the formula
[Number 1]
_{R2 (B+α)} =(xR2-xR1)α+ _{R1 (B+α)} (1)

In this way, the R values of the lighting fixtures 4-1 and 4-2 are the same (R _1(B) =R _2(B) ), and an environment with a uniform hue as a whole corresponding to the ambient light is realized. In this state, by changing the operation amount of the R component of the lighting device 4-1, the lighting device 4-2 can be changed to the same color as the device light of the lighting device 4-1. In other words, the R components of the lighting fixtures 4-1 and 4-2 can be changed in the same way in appearance.

As for the G and B components of the lighting fixtures 4-1 and 4-2, similarly to the case of the R component, by changing the manipulated variables of the G and B components of the lighting fixture 4-1, -2 can be changed to the same color as the fixture light of the lighting fixture 4-1. In other words, the G and B components of the lighting fixtures 4-1 and 4-2 can be changed visually in the same way.

Therefore, for example, the lighting fixtures 4-1 and 4-2 shown in FIG. 1 can have the same appearance color change, and an environment with a uniform color tone can be realized as a whole.

It should be noted that generalizing the above formula (1) is represented by the following formula.
[Number 2]
Ci _(B+α) =( _xCi -xC1)α+ _{C1 (B+α)} (2)
C indicates an arbitrary RGB color component, and i indicates the number of the lighting fixtures 4-1, 4-2, . . . (i is a positive integer and i>1).

Also, the above description is for the lighting fixture 4-1 and the lighting fixture 4-2 which are the reference lighting fixtures, but the same applies to the lighting fixture 4-1 and other lighting fixtures. As a result, all lighting fixtures 4-1, 4-2, . . . can be uniform in appearance.

5 and 6, in processing by the instrument light characteristic measurement unit 11, the first lighting processing unit 10 shown in FIG. As a result, an environment with a uniform color tone is realized as a whole.

That is, the color of the ambient light matches the measurement result of the light of the lighting fixtures 4-1, 4-2, . . . It is assumed that the operation amounts of the lighting fixtures 4-1, 4-2, . The first illumination processing section 10 outputs the recorded values to the reference value setting section 20 and the characteristic calculating section 22 of the instrument light characteristic measuring section 11 .

Here, the recorded values output by the first lighting processing unit 10 are the operation amount (SR _1(B) , SG _1(B) , SB _1(B) ) of the lighting fixture 4-1 and the corresponding fixture light Measurement results (R _1(B) , G _1(B) , B _1(B) ), operation amounts of lighting fixture 4-2 (SR _2(B) , SG _2(B) , SB _2(B) ) and corresponding measurement results of instrument light (R _2(B) , G _2(B) , B _2(B) ), . . . R1 _(B) =R2 _(B) =..., G1 _(B) =G2 _(B) =..., B1 _(B) =B2 _(B) =...

The reference value setting unit 20 of the fixture light characteristic measuring unit 11 is operated by the lighting operator OP to change the fixture light, and when the operation mode is changed to the reference fixture light change measurement mode, the lighting fixture 4- One reference lighting fixture is selected from 1, 4-2, . . . (step S601). Here, it is assumed that the reference value setting unit 20 selects the lighting fixture 4-1 as the reference lighting fixture.

The reference value setting unit 20 receives the recorded values from the first lighting processing unit 10, selects the requested light color to be measured first from, for example, RGB colors, and uses the recorded values input from the first lighting processing unit 10. From the values, the manipulated variable (SR _1(B) , SG _1(B) , SB _1(B) ) of the lighting fixture 4-1, which is the reference lighting fixture, is extracted. Then, the reference value setting unit 20 sets a predetermined amount of α (eg, 10%) to the required light color (eg, the R component) with respect to the manipulated variables (SR _1(B) , SG _1(B) , SB _1(B) ). ) is added to set a new manipulated variable (SR _{1 (B)} + α, SG _{1 (B)} , SB _{1 (B)} ) (manipulated variable + α), and a new manipulated variable (SR _{1 (B)} + α, SG _1(B) , SB _1(B) ) are output (transmitted) to the illumination processing device 3-1 (step S602).

As a result, the new manipulated variable (SR _1(B) +α, SG _1(B) , SB _1(B) ) is input from the lighting processing device 3-1 to the lighting fixture 4-1. , fixture light corresponding to the new manipulated variable (SR _1(B) +α, SG _1(B) , SB _1(B) ) is emitted. Then, in the illumination processing device 3-1, fixture light corresponding to the new manipulated variable (R _1(B) +α, G _1(B) , B _1(B) ) is measured as the reference light.

Measurement results (R _{1 (B+α)} , G ₁ ( _{B )} , B _{1( B)} ) is sent from the illumination processing device 3-1 to the reference value setting unit 20. FIG. The reference value setting unit 20 inputs (receives) the reference light measurement results (R _1(B+α) , G _1(B) , B _1(B) ) from the lighting processing device 3-1, and uses them as a reference. The values are set to (R _1(B+α) , G _1(B) , B _1(B) ) (step S603).

The reference value setting unit 20 outputs the reference value to the measurement unit 21 for the selected requested light color. Further, the reference value setting unit 20 changes the operation amount +α of the requested light color of the lighting fixture 4-1, which is the reference lighting fixture, to the operation amount +α, and the measurement result of the reference light corresponding to the operation amount +α. is stored as a recorded value and output to the characteristic calculator 22 .

For example, when the R component, which is the requested light color, is selected, the reference value setting unit 20 sets the reference values (R _1(B+α) , G _1(B) , B _1(B) ) to the measurement unit 21. Output. In addition, the reference value setting unit 20 sets the operation amount (SR _1(B) +α, SG _1(B) , SB _1(B) ) and the corresponding reference light measurement result (R _1(B+α) , G _1(B) , B _1(B) ) are stored as recorded values, and the recorded values are output to the characteristic calculator 22 .

When the illumination operator OP performs an operation to measure the characteristics of the fixture light and the operation mode is changed to the fixture change measurement mode, the measurement section 21 receives the reference value (R _{1 (B +α)} , G _1(B) , B _1(B) ) to select the lighting fixture 4-2 as the first lighting fixture (step S604). Then, the fixture light control section 30-2 of the measurement section 21 corresponding to the lighting fixture 4-2 receives from the lighting processing device 3-2 the measurement result of the fixture light of the lighting fixture 4-2 (R _2(B) , G _2(B) , B _2(B) ) are input (received) (step S605).

The instrument light control unit 30-2 controls instrument light measurement results (R _2(B) , G _2(B) , B _2(B) ) and reference values (R _1(B+α) , G _1(B) , B _{1(B) )} to zero the difference between them. The manipulated variable is calculated by control for setting the difference between R _{1 (B+α)} to 0. Then, the fixture light control unit 30-2 outputs (transmits) the operation amount to the illumination processing device 3-2 (step S606).

As a result, the operation amount is input from the lighting processing device 3-2 to the lighting fixture 4-2, and the lighting fixture 4-2 emits light corresponding to the operation amount. Then, the measurement result of the fixture light corresponding to the manipulated variable is transmitted from the illumination processing device 3-2 to the fixture light control section 30-2.

FIG. 7 is a block diagram showing a configuration example of the fixture light control section 30-2. The instrument light control section 30-2 includes a subtraction section 40, a control section 41 and a switching section .

The subtraction unit 40 inputs the reference values (R _1(B+α) , G _1(B) , B _1(B) ) from the reference value setting unit 20, and measures the fixture light from the illumination processing device 3-2. Input the results (R _2(B) , G _2(B) , B _2(B) ) and calculate the fixture light from the reference values (R _1(B+α) , G _1(B) , B _1(B) ). The difference is obtained by subtracting the measurement results (R _2(B) , G _2(B) , B _2(B) ) of , and the difference is output to the control unit 41 . Here, the measurement result of the first instrument light is (R _2(B) , G _2(B) , B _2(B) ) and R _1(B+α) ≠R _2(B) ,G _{1( B)} = G _2(B) , B _1(B) = B _2(B) , but as the control by the subsequent control unit 41 progresses, G _1(B) = G _2(B) , B _{1( B)} =B _{2 (B)} , R _{2 (B)} , which is the R value of the instrument light measurement result, approaches R _{1 (B+α)} .

The control unit 41 receives the difference from the subtraction unit 40 , calculates the operation amount by performing control so that the difference becomes 0, and outputs the operation amount to the switching unit 42 .

The switching unit 42 inputs the operation amount from the control unit 41 . The switching unit 42 also receives a switching signal indicating manual operation and a manual operation amount (an operation amount finely adjusted manually in step S611, which will be described later) from an operation amount adjustment unit 31-2, which will be described later.

The switching unit 42 determines that the operating state is automatic when a switching signal indicating manual operation is not input, and transmits the operation amount input from the control unit 41 to the lighting processing device 3-2. On the other hand, when a switching signal indicating manual operation is input from the operation amount adjustment unit 31-2, the switching unit 42 determines that the operating state is manual, and changes the manual operation amount input from the operation amount adjustment unit 31-2. It is transmitted to the illumination processing device 3-2.

Returning to FIGS. 5 and 6, the instrument light control unit 30-2 determines whether the difference in step S606 is the minimum (whether it is smaller than a predetermined threshold) (step S607). If the instrument light control unit 30-2 determines in step S607 that the difference is not the smallest (if it is determined that it is not smaller than the threshold value) (step S607: N), the process proceeds to step S605. With such feedback control, the processing of steps S605 to S607 is repeated, and the measurement result of the fixture light of the lighting fixture 4-2, for example, approaches the reference value.

On the other hand, if the instrument light control unit 30-2 determines in step S607 that the difference is the minimum (determines that it is smaller than the threshold value) (step S607: Y), the operation amount when the difference is the minimum An output level is determined (step S608).

As a result, the fixture light control unit 30-2 continues to transmit the manipulated variable of the output level determined in step S608 as the fixed manipulated variable, thereby manipulating the fixture light of the lighting fixture 4-2. Then, the lighting fixture 4-2 becomes illumination of the fixture light corresponding to the fixed operation amount, and the measurement result of the fixture light of the lighting fixture 4-2 becomes a constant value.

The measurement unit 21 determines whether or not the operation amount output level determination process in step S608 has been completed for all the lighting fixtures (the lighting fixtures 4-2, . . . ) (step S609).

If the measurement unit 21 determines in step S609 that all lighting fixtures have not been completed (step S609: N), it selects the next lighting fixture (step S610), and proceeds to step S605. The measurement unit 21 selects, for example, the lighting fixture 4-3 as the lighting fixture next to the lighting fixture 4-2.

As a result, the processing of steps S605 to S608 is performed for the next lighting fixture 4-3, and in step S608, the output level of the manipulated variable when the difference is the smallest is determined. Then, the processing of steps S605 to S608 is performed for all lighting fixtures.

If the measurement unit 21 determines in step S609 that all lighting fixtures have been completed (step S609: Y), the measurement unit 21 outputs the manipulated variable of the requested light color selected in step S602 for all lighting fixtures. Judge that the determination of the level is completed. Then, the measurement unit 21 instructs the lighting operator OP to manually finely adjust the operation amount of the requested light color for all the lighting fixtures (step S611).

When the operation amount adjustment unit 31-2 of the measurement unit 21 inputs the manually finely adjusted operation amount of the required light color for the lighting fixture 4-2 according to the operation of the lighting operator OP, it is manually adjusted to the required light color. is output to the fixture light control section 30-2 together with a switching signal indicating manual operation.

When the fixture light control unit 30-2 receives a switching signal indicating manual operation and a manual operation amount of the requested light color from the operation amount adjustment unit 31-2, the fixture light control unit 30-2 outputs the operation amount including the operation amount of the requested light color to the lighting processing device. Send to 3-2.

For example, let the first requested light color be the R component, and let the manipulated variable whose output level is determined in step S608 be (SR _2(B) +α _R2′ , SG _2(B) , SB _2(B) ). Assume that the manual operation amount of the R component, which is the light color, is (SR _2(B) +α _R2 ). Then, the fixture light control unit 30-2 sets the R component for the operation amount (SR _2(B) +α _R2′ , SG _2(B) , SB _2(B) ) whose output level has been determined in step S608. , reflecting the manual operation amount (SR _2(B) +α _R2 ), and applying the new operation amount (SR _2(B) +α _R2 , SG _2(B) , SB _2(B) ) to the illumination processing device 3-2 Send to

As a result, a new operation amount (SR ₂ ( _{B )} +α _R2 , Instrument lights corresponding to SG _2(B) and SB _2(B) ) are emitted. Let the measurement result of the instrument light at this time be (R _2(B+α) , G _2(B) , B _2(B) ).

When the R component, which is the requested light color, is selected, the measurement unit 21 calculates the operation amount (SR _2(B) +α _R2 , SG2 _(B) , SB2 _(B) ) and the corresponding instrument light measurement results (R2 _(B+α) , G2 _(B) , B2 _(B) ) are stored as recorded values. and outputs the recorded value to the characteristic calculator 22 .

The operation amount adjustment section 31-3 and the instrument light control section 30-3 also perform the same processing as the operation amount adjustment section 31-2 and the instrument light control section 30-2. Then, when the R component, which is the requested light color, is selected, the measurement unit 21 determines the operation amount (SR _{3(B )} + α _R3 , SG _3(B) , SB _3(B) ) and the corresponding instrument beam measurements (R _3(B+α) , G _3(B) , B _3(B) ) are recorded. , and output the recorded value to the characteristic calculator 22 .

That is, the measuring unit 21 calculates the measured value of the fixture light of the lighting fixture and the reference Control is performed so that the difference from the reference value, which is the light measurement result, is 0, and the recorded value, which is composed of the manually finely adjusted operation amount and the corresponding instrument light measurement result, is output to the characteristic calculation unit 22. .

The reference value setting unit 20 proceeds from step S611 and determines whether or not the processing of steps S603 to S611 has been completed for all requested light colors (step S612).

When the reference value setting unit 20 determines in step S612 that the processing of steps S603 to S611 has not been completed for all requested light colors (step S612: N), it selects the requested light color to be measured next. do. The reference value setting unit 20 also sets the operation amount (SR _1(B) , SG _1(B) , SB _1(B) ), a new manipulated variable (SR _1(B) , SG _1(B) +α, SB _{1 (B)} ) (manipulated amount + α) is set. Then, the reference value setting unit 20 outputs (transmits) new manipulated variables (SR _1(B) , SG _1(B) +α, SB _1(B) ) to the illumination processing device 3-1 (step S613). , the process proceeds to step S603.

As a result, the processing of steps S603 to S611 is performed for the next requested light color, and in step S611, for the requested light color, manual fine adjustment of the operation amount of the requested light color is performed for all lighting fixtures. .

Then, the processing of steps S603 to S611 is performed for all the requested light colors, and the manual fine adjustment of the operation amount of the requested light colors is completed for all the lighting fixtures. Therefore, when the operation amount of the lighting fixture 4-1, which is the reference lighting fixture, is changed, the measurement results of the fixture light of the lighting fixtures 4-2, . . . A reference value can be tracked.

If the reference value setting unit 20 determines in step S612 that the processing of steps S603 to S611 has been completed for all requested light colors (step S612: Y), the process proceeds to step S614.
