The present invention relates to a color illuminator control device, and more particularly, to a color illuminator control device providing a human friendly interface.

Light can be expressed in several color models. In lighting, three colors of light, red, green, and blue, are added and mixed to express various colors. The color combination by the three light sources of RGB can express almost all colors according to the brightness degree of each light source, but it is very difficult for a user to create a desired color by combining the three light sources of RGB. For example, if you want to create yellow, you need to mix red and green half and half, and if you want to express saturation, you also need to mix blue. You need to know exactly how much RGB should be mixed and in what proportion to achieve the color and saturation you want to express. It is very difficult to control.

1 is a block diagram showing a conventional color illuminator control device. This color illuminator control has a red upswitch 11 and red downswitch 12 for adjusting red illumination, a green upswitch 13 and green downswitch 14 for adjusting green illumination, blue illumination The blue upswitch 15 and the blue downswitch 16 to adjust the value of each switch and the red size value R (v), the green size value G (v) and the blue size value ( A switch input unit 17 for generating and outputting B (v)) and a control signal for illuminating the control signal for illuminating the color according to the red size value, the green size value and the blue size value output from the switch input unit 17. And a control signal output unit 18 for outputting the control signal.

The illuminator 19 includes a triac control illuminator, a PWM control illuminator, a DMX-512 control illuminator and the like according to its control characteristics. In addition, the control signal output unit 18 includes a triac controller, a PWM controller, a DMX-512 controller, and the like according to the control characteristics of the color tone specifier 19.

The operation of the color illuminator controller is as follows. Manipulate each switch to illuminate the color you want. That is, the red up switch 11 and the red down switch 12 are operated to obtain a desired red size value, and the green up switch 13 and the green down switch 14 are operated to obtain a desired green size value. Manipulate the blue upswitch 15 and blue downswitch 16 to obtain the desired blue size value. The switch input unit 17 transmits the red size value R (v), the green size value G (v), and the blue size value B (v) to the control signal output unit 18 according to the operation of each switch. Output The control signal output unit 18 outputs a control signal necessary for the illuminator 19 according to the red size value, the green size value, and the blue size value.

If the control signal output unit 18 is a triac controller and the illuminator 19 is a triac control illuminator, the control signal output unit 18 has a red magnitude value R (v) and a green magnitude value G (v). And the blue magnitude value B (v) is converted into a phase delay signal and output to the illuminator 19. If the control signal output unit 18 is a PWM controller and the illuminator 19 is a PWM control illuminator, the control signal output unit 18 has a red size value R (v) and a green size value G (v) and a blue color. The magnitude value B (v) is converted into a PWM (pulse width modulation) signal and output to the illuminator 19. If the control signal output unit 18 is a DMX-512 controller and the illuminator 19 is a DMX-512 control illuminator, the control signal output unit 18 has a red size value R (v) and a green size value G (v). ) And the blue size value B (v) are converted into the DMX-512 signal and output to the illuminator 19.

Since the conventional color illuminator controller is RGB-based, the user needs to perform several complicated switch operations to accurately match the color and saturation desired by the user. In addition, when the user does not have enough knowledge of the three primary colors of light, it is very difficult to accurately adjust the desired color and saturation by manipulating the red / green / blue up / down switches.

Next, the variable Temp1 is set to '2 * I (v) -Temp2' (S907). Next, a value of 'Temp1' is assigned to the variable V1, 'Temp2' is assigned to the variable V2, and the variable V3dp 'H (v) +1/3' is substituted (S908) to perform an operation subroutine (S1000). . Detailed description of the operation subroutine will be described later with reference to FIG. As a result of performing the operation subroutine, when the operation result value is returned, the returned result value is set to the red value R (v) (S909).

If V3 is not less than 0 and not greater than 1, it is determined whether 6 * V3 is less than 1 (S1005).

If 6 * V3 is smaller than 1 as a result of the determination in step S1005, 'V1 + (V2-V1) * 6 * V3' is set as a result value (S1006).

If it is determined in step S1005 that 6 * V3 is not less than 1, it is determined whether 2 * V3 is less than 1 (S1007). If 2 * V3 is smaller than 1 as a result of the determination in step S1007, 'V2' is set as a result (S1008).

As a result of the determination in step S1007, if 2 * V3 is not smaller than 1, it is determined whether 3 * V3 is smaller than 2 (S1009). If 3 * V3 is smaller than 2 as a result of the determination in step S1009, 'V1 + (V2-V1) * 2 / 3-V3) * 6' is set as a result value (S1010).

If 3 * V3 is not less than 2 as a result of the determination in step S1009, 'V1' is set as a result value (S1011).

After performing steps S1006, S1008, S1010, and S1011, the result value is returned to the main routine.
