Abstract
A control device controls an illumination device that illuminates a surrounding area, and an effect-producing device that emits light producing an effect on the surrounding area. The control device includes a control unit that controls at least one of a color of first light emitted by the illumination device and a color of second light emitted by the effect-producing device so that at least one of the color of the first light and the color of the second light moves into a specified chromaticity range, the color of the first light and the color of the second light being outside of the specified chromaticity range. Colors in the specified chromaticity range are recognized as a same color by a human.
Claims24
A controller that controls an illumination device that illuminates a surrounding area, and an effect-producing device that emits light producing an effect on the surrounding area,
- wherein the controller is configured to control at least one of a color of first light emitted by the illumination device and a color of second light emitted by the effect-producing device so that at least one of the color of the first light and the color of the second light moves into a specified chromaticity range, the color of the first light and the color of the second light being outside of the specified chromaticity range, and
- colors in the specified chromaticity range are recognized as a same color by a human.
A controller configure to control a first illumination device for emitting first light and a second illumination device for emitting second light having a different configuration than the first illumination device,
- wherein the controller is configured to adjust at least one of the first illumination device and the second illumination device so that a difference between an adjusted first color of the first light after the adjustment and an adjusted second color of the second light after the adjustment is within a predetermined chromaticity range, and
- the predetermined chromaticity range is a range with which a human recognizes that the adjusted first color of the first light after the adjustment and the adjusted second color of the second light after the adjustment are a same color.
A controller that controls an illumination device that illuminates a surrounding area, and an effect-producing device that emits light producing an effect on the surrounding area,
- wherein the controller is configured to adjust at least one of a first initial color of first light emitted by the illumination device and a second initial color of second light emitted by the effect-producing device so that a difference between an adjusted first initial color of the first light after the adjustment and an adjusted second initial color of the second light after the adjustment is within a predetermined chromaticity range, and
- the predetermined chromaticity range is a range with which a human recognizes that the adjusted first initial color of the first light after the adjustment and the adjusted second initial color of the second light after the adjustment are a same color.
A controller that controls an illumination device that illuminates a surrounding area and emits first light having a first color, and an effect-producing device that emits light producing an effect on the surrounding area and emits second light having a second color,
- wherein the controller is configured to control at least one of the illumination device and the effect-producing device to adjust at least one of the first light and the second light,
- before adjustment by the controller, the first light has a first initial color having a first n-step MacAdam ellipse, and the second light has a second initial color having a second n-step MacAdam ellipse, n being 1, 2, 3 or 4,
- when the first initial light is not within the second n-step MacAdam ellipse and the second initial light is not within the first n-step MacAdam ellipse, the controller is configured adjust at least one of the first initial light and the second initial light such that a first adjusted light after the adjustment is within a second n-step MacAdam ellipse after the adjustment or a second adjusted light is within a first n-step MacAdam ellipse after the adjustment.
A controller that controls an illumination device that illuminates a surrounding area, and an effect-producing device that emits light producing an effect on the surrounding area,
- wherein when a first color of first light emitted by the illumination device and a second color of second light emitted by the effect-producing device are expressed in CIE xy chromaticity coordinates, and when at least a 3-step MacAdam ellipse of the second color of the second light is outside of at least a 3-step MacAdam ellipse of the first color of the first light,
- the controller is configured to cause the first color of the first light to move to outside of the at least 3-step MacAdam ellipse that includes, as a center, a position expressed in CIE xy chromaticity coordinates for the first color of the first light before being approximated to the second color of the second light.
A controller that controls an illumination device that illuminates a surrounding area, and an effect-producing device that emits light producing an effect on the surrounding area,
- wherein when a first color of first light emitted by the illumination device and a second color of second light emitted by the effect-producing device are expressed in CIE xy chromaticity coordinates, and when at least a 3-step MacAdam ellipse of the second color of the second light is outside of at least a 3-step MacAdam ellipse of the first color of the first light,
- the controller is configured to cause the first color of the first light to move into the at least 3-step MacAdam ellipse that includes, as a center, a position expressed in CIE xy chromaticity coordinates for the second color of the second light before being approximated to the second color of the second light.
A controller that controls an illumination device that illuminates a surrounding area, and an effect-producing device that emits light producing an effect on the surrounding area,
- wherein when a first color of first light emitted by the illumination device and a second color of second light emitted by the effect-producing device are expressed in CIE xy chromaticity coordinates, and when at least a 3-step MacAdam ellipse of the first color of the first light is outside of at least a 3-step MacAdam ellipse of the second color of the second light,
- the controller is configured to cause the second color of the second light to move to outside of the at least 3-step MacAdam ellipse that includes, as a center, a position expressed in CIE xy chromaticity coordinates for the second color of the second light before being approximated to the first color of the first light.
A controller that controls an illumination device that illuminates a surrounding area, and an effect-producing device that emits light producing an effect on the surrounding area,
