(Embodiment)
<Configuration and Function: Lighting Production System 1>
A lighting effect system 1 according to an embodiment will be described below.

Figure 1 is a block diagram showing a lighting system 1 according to an embodiment.

As shown in FIG. 1, the lighting production system 1 is a lighting production system that can cause lighting fixtures 30 arranged on multiple illumination objects to emit light in the same color as a specific pixel included in the image content. The lighting production system 1 can demonstrate an illumination scene in which multiple illumination objects are integrated by using information indicating an illumination scene corresponding to the image content. Here, the information indicating the illumination scene includes information for controlling the lighting fixtures 30, such as the dimming rate for each pixel included in the image content, the color adjustment rate for each pixel included in the image content, and fade time. The illumination objects are non-transparent objects that can emit light, such as buildings such as buildings or houses, road surfaces, and banners.

Image content includes still image content in which the color of a specific pixel remains constant, and video content in which the color of a specific pixel changes over time. Therefore, when lighting production system 1 performs light production on multiple illuminated objects based on information indicating a lighting scene, it is possible to reflect the change in pixel color over time in the light emission color of lighting device 30 by generating information indicating a lighting scene corresponding to the change in pixel color over time. For example, if the image content is content that expresses the movement of a polka dot pattern, the color change corresponding to the movement of the polka dot pattern corresponding to a specific pixel in the image content is reflected in the light emission color of lighting device 30. Furthermore, the image content is not limited to images of polka dot patterns, and may be images of clouds, fireworks, fountains, rainbows, auroras, etc.

At this time, each of the multiple lighting fixtures 30 is associated with a pixel of the image content.

Figure 2 is a diagram showing an example of the correspondence between multiple lighting fixtures 30 and image content. In Figure 2, two buildings arranged adjacent to each other are shown as multiple illumination objects. In this embodiment, one of the two illumination objects may be called the first illumination object, and the other of the two illumination objects may be called the second illumination object.

As shown in FIG. 2, the range R1a specified for the image content is associated with the performance area R1c of the outer wall of the first irradiation object, and the range R2a specified for the image content is associated with the performance area R2c of the outer wall of the second irradiation object. Note that since the performance area R2c is smaller than the irradiation area R2, the lighting scene is not executed in the part of the irradiation area R2 that extends beyond the performance area R2c (the area of the irradiation area R2 excluding the performance area R2c), and the lighting device 30 is not lit. Furthermore, the ranges R1a and R2a are of the same size, and the ranges R1b and R2b are of the same size.

Here, the illumination area is the maximum area that multiple lighting fixtures 30 can illuminate on an illumination target. The performance area is the area of light illuminated on an illumination target by one or more lighting fixtures 30.

The range R1b specified for the image content is associated with the performance area R1d of the outer wall of the first irradiation object, and the range R2b specified for the image content is associated with the performance area R2d of the outer wall of the second irradiation object. Note that since the performance area R1d is larger than the irradiation area R1, the lighting scene is not executed in the part of the performance area R1d that extends beyond the irradiation area R1 (the area of the performance area R1d excluding the irradiation area R1) because no lighting fixtures 30 are present. The irradiation area R1 and the irradiation area R2 are defined by the coordinates of the spatial information.

In this way, each lighting device 30 is associated with a pixel of the image content and emits light in the same color as that pixel.

In such a lighting system 1, as shown in Figures 1 and 2, the lighting control device 10 can coordinate multiple lighting fixtures 30 to perform lighting effects.

The lighting system 1 includes a plurality of lighting fixtures 30 and a processing terminal 2.

[Lighting fixture 30]
The lighting fixtures 30 are installed on the respective illumination objects and irradiate the illumination objects with light. Specifically, the lighting fixtures 30 are installed on the outer walls of the illumination objects so that the lighting fixtures 30 can irradiate the outer walls of the illumination objects on which they are installed. In FIG. 2, the lighting fixtures 30 are installed on the first illumination object and the second illumination object, respectively.

When the exterior walls of the first and second irradiation objects are viewed from a specified point along a direction perpendicular to the arrangement direction of the first and second irradiation objects, the multiple lighting fixtures 30 are installed on the exterior walls facing the specified point. Therefore, the multiple lighting fixtures 30 form one lighting performance area consisting of at least the exterior walls of the two adjacent first and second irradiation objects. The lighting performance area is an area in which light can be irradiated onto these exterior walls by the multiple lighting fixtures 30, and is the combined area of the performance area of the first and second irradiation objects.

Each of the lighting fixtures 30 has a dimming control function and a color adjustment control function. Each of the lighting fixtures 30 acquires information indicating a lighting scene from the lighting control device 10, and executes a dimming control function and a color adjustment control function according to the information indicating the lighting scene.

Each of the lighting fixtures 30 has a red light source, a green light source, and a blue light source. The red light source, the green light source, and the blue light source emit light according to information indicating a lighting scene in which a light emission color and a light emission brightness for each light emission color are specified. Each of the lighting fixtures 30 may also include a white light source or a yellow light source in addition to the red light source, the green light source, and the blue light source.

The red light source, green light source, and blue light source are each realized by an LED (Light Emitting Diode) chip or the like, and the light emission brightness of each light source can be controlled independently. This allows the light emission color of the lighting device 30 to be changed. Each of the red light source, green light source, and blue light source may be realized by a light emitting module using a semiconductor light emitting element such as a semiconductor laser, or a solid-state light emitting element such as an organic EL (Electro Luminescence) or inorganic EL.

[Processing terminal 2]
The processing terminal 2 is an operation terminal operated by a user, and is a personal computer, a smartphone, etc. The user uses the processing terminal 2 to generate information indicating an illumination scene.

Specifically, the processing terminal 2 has a lighting control device 10 and a display device 15.

The lighting control device 10 transmits information indicating a lighting scene to each of the multiple lighting fixtures 30, and can cause the multiple lighting fixtures 30 to perform the lighting scene indicated in the information. In other words, the lighting production system 1 can perform a lighting scene for multiple illumination targets by changing the dimming rate and/or color adjustment rate of the light emitted from each of the multiple lighting fixtures 30 over time or by keeping the dimming rate and/or color adjustment rate constant based on the information indicating the lighting scene.

The lighting control device 10 includes a memory unit 13, a processing unit 11, and a display control unit 12.

The memory unit 13 stores information about multiple lighting fixtures and image content. In the present embodiment, the memory unit 13 stores one or more image contents. The information about lighting includes a background image including an illumination target illuminated by light from the multiple lighting fixtures 30, spatial information indicated by the background image, and position information for each of the multiple virtual lighting fixtures 30a arranged on the background image.

In addition, the memory unit 13 may store background images, image content, etc., by the processing terminal 2 acquiring the background images, image content, etc. from the distribution server.

The background image is an image including an illumination object onto which light from the lighting device 30 is irradiated, that is, an image including an illumination object on which a lighting scene is performed. The background image may include multiple illumination objects. The background image may also be composed of only illumination objects.

As shown in FIG. 3A, the spatial information is set according to each background image. FIG. 3A is a diagram showing spatial information and a background image. The spatial information is information indicating, for example, three-dimensional coordinates that define the position of the irradiation object in the background image, the size (length, width, height) and shape of the irradiation object, etc., and three-dimensional coordinates that define the size of the irradiation area, the position of the irradiation area, the shape of the irradiation area, etc.

The position information is information indicating the position coordinates of the virtual lighting fixture 30a placed on the illumination target on the background image, as shown in FIG. 3B. In other words, the position information is information indicating the position coordinates in the spatial information. FIG. 3B is a diagram showing the position information of the virtual lighting fixture 30a and the ID of the virtual lighting fixture 30a. The position information is also linked to an ID that identifies each virtual lighting fixture 30a. The ID of the virtual lighting fixture 30a corresponds to the ID of the actual lighting fixture 30. The lighting information also includes information on the size of the light emission surface of the lighting fixture 30, the light emission direction of the lighting fixture 30, etc., and this information may be linked to the position information.

The storage unit 13 includes, for example, a primary storage device such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The storage unit 13 may also include a secondary storage device such as a HDD (Hard Disk Drive) or an SSD (Solid State Drive), and a tertiary storage device such as an SD card.

The processing unit 11 unifies the size of the lighting scene, which is the performance of the light irradiated on the multiple irradiation objects, based on the spatial information in the information on the multiple lighting. Then, the processing unit 11 synthesizes information on two or more lightings among the information on the multiple lightings into one. For example, the processing unit 11 synthesizes information on the lighting on the first irradiation object and information on the lighting on the second irradiation object into one. When the processing unit 11 unifies the size of the lighting scene, it simulates it in a virtual space that imitates a background image. Here, synthesis means unifying the size of multiple spatial information to consolidate them into one spatial information. Specifically, synthesis means, as shown in Figures 4A and 4B, forming a pseudo-one performance area, that is, one lighting performance area, by unifying the size of the performance area of the first irradiation object and the size of the performance area of the second irradiation object and synthesizing the two. Figure 4A is a diagram showing the irradiation area R1 and the performance area R1c of the first irradiation object in the virtual space, and the irradiation area R2 and the performance area R2c of the second irradiation object. FIG. 4B is another diagram showing the irradiation area R1 and performance area R1d of the first irradiation object, and the irradiation area R2 and performance area R2d of the second irradiation object in the virtual space.

For example, when adjusting the size of the lighting scene to be performed on the outer wall of the first illumination object and the size of the lighting scene to be performed on the outer wall of the second illumination object, the sizes of the lighting scenes are unified by adjusting the sizes of the lighting scenes to be performed on both outer walls. Here, the size of the lighting scene refers to the size of the performance area.

Therefore, in the image content superimposed on the combined information (composite information) related to the lighting that has been combined by the processing unit 11, for example, the size of the polka dot pattern represented as an illumination scene on the first illuminated object and the size of the polka dot pattern represented as an illumination scene on the second illuminated object will be similar.

In addition, the processing unit 11 may unify the size of a lighting scene, which is a light presentation that is irradiated onto multiple illumination targets, based on spatial information in the information about one of the multiple illuminations.

For example, when adjusting the size of the lighting scene to be performed on the outer wall of the first irradiation object and the size of the lighting scene to be performed on the outer wall of the second irradiation object, the size of one of the lighting scenes is adjusted based on the size of the other lighting scene, thereby unifying the sizes of the lighting scenes. For example, as shown in FIG. 4A, the processing unit 11 sets the performance area R2c of the second irradiation object to be smaller than the irradiation area R2 when the irradiation area R1 of the first irradiation object is used as the reference. Also, as shown in FIG. 4B, the processing unit 11 sets the performance area R1d of the first irradiation object to be larger than the irradiation area R1 when the irradiation area R2 of the second irradiation object is used as the reference.

Even in this case, in the image content that the processing unit 11 superimposes on the composite information, for example, the size of the polka dot pattern represented as an illumination scene on the first illuminated object and the size of the polka dot pattern represented as an illumination scene on the second illuminated object will be similar.

The processing unit 11 also generates, based on the synthesis information and the image content, a plurality of lighting scenes that can be reproduced as a single lighting scene in which two or more illumination objects are illuminated by a plurality of lighting devices 30 corresponding to a plurality of virtual lighting devices 30a included in the synthesis information. In other words, the processing unit 11 generates information indicating a lighting scene that can demonstrate a desired lighting scene by simulating the lighting scene in a virtual space using the synthesis information.

Figure 5 shows a processing terminal 2 and a display device 15 of the processing terminal 2, as well as a background image and multiple virtual lighting fixtures 30a displayed on the display device 15.

As shown in FIG. 5, the display control unit 12 can cause the processing unit 11 to display the composite information on the display screen 15a of the display device 15. The display control unit 12 can also add an image that simulates a lighting scene to the composite information and display it.

The display device 15 is, for example, a liquid crystal display, an organic EL display, etc. The display device 15 can display a background image, and a plurality of virtual lighting fixtures 30a arranged in the background image. The display device 15 can also execute the generated lighting information to display an image simulating a lighting scene using a plurality of virtual lighting fixtures 30a arranged in the background image.

[Processing Operation]
Next, the processing operations of the lighting control device 10, the lighting performance system 1, and the lighting control method according to the present embodiment will be described.

Figure 6 is a flowchart showing the processing operation of the lighting production system 1 according to the embodiment.

The user operates the processing terminal 2 to start the lighting performance creation tool. The user selects a background image including the first illumination object and a background image including the second illumination object stored in the memory unit 13. As a result, the background image including the first illumination object and the background image including the second illumination object are displayed on the display screen 15a of the display device 15.

First, as shown in FIG. 6, the user operates the processing terminal 2 to place multiple virtual lighting fixtures 30a on a background image displayed on the display screen 15a, and the display control unit 12 causes the display device 15 to display an image in which multiple virtual lighting fixtures 30a are placed on the background image (S11). At this time, the processing unit 11 places multiple virtual lighting fixtures 30a at position coordinates in a virtual space that mimics the background image. Then, the processing unit 11 links the position coordinates of the virtual lighting fixtures 30a placed in the background image to the IDs of the virtual lighting fixtures 30a.

Next, the processing unit 11 generates composite information by combining information about two or more lights in the virtual space displayed on the display screen 15a (S12).

Specifically, when creating an illumination scene on a first illumination object and a second illumination object, the processing unit 11 combines information about the illumination on the first illumination object (referred to as information about the first illumination) with information about the illumination on the second illumination object (referred to as information about the second illumination).

For example, when combining information about the first lighting and information about the second lighting, the size of the performance area R2c of the second lighting object shown in the information about the first lighting is changed to match the size of the irradiation area R1 of the first lighting object, thereby unifying the two sizes. In other words, the size of the performance area R2c of the second lighting object is set small so that it is the same size as the irradiation area R1 of the outer wall of the first lighting object. In this way, the processing unit 11 generates information about lighting that indicates the combined lighting performance areas R1c and R2c. The combined lighting performance areas R1c and R2c are the size of the image content expressed on the outer walls of the two adjacent first lighting objects and the outer wall of the second lighting object by the lighting scene.

In this case, the illumination area R2 of the second illumination object is larger than the illumination area R1 of the first illumination object, that is, larger than the performance area R2c of the second illumination object. Therefore, the lighting scene is not executed in the part of the illumination area R2 that extends beyond the performance area R2c.

Furthermore, taking the second illuminated object shown in the information about the second lighting as a reference, the size of the performance area R1d of the first illuminated object shown in the information about the first lighting is changed to match the size of the illumination area R2 of the second illuminated object, thereby unifying the two sizes. In other words, the size of the performance area R1d of the first illuminated object is set large so that it is the same size as the illumination area R2 of the outer wall of the second illuminated object. In this way, the processing unit 11 generates information about lighting that indicates the lighting performance areas R1d and R2d that have been combined into one.

In this case, the illumination area R1 of the first illumination object is smaller than the illumination area R2 of the second illumination object, that is, smaller than the performance area R1d of the first illumination object. Therefore, in the part of the performance area R1d that extends beyond the illumination area R1, no lighting fixtures 30 are present, and therefore no lighting scene is executed.

Next, the user operates the processing terminal 2 to generate information indicating a desired lighting scene. That is, the processing unit 11 simulates a lighting scene on the composite information, i.e., on a single composite lighting production area, in a virtual space that mimics the background image. At this time, the display control unit 12 displays the lighting scene simulated in the virtual space on the display screen 15a. Then, the user operates the processing terminal 2 to set a desired lighting scene, and the processing unit 11 generates information indicating the lighting scene (S13).

Next, the lighting control device 10 transmits information indicating the generated lighting scene to the multiple lighting fixtures 30, which then execute the information indicating the lighting scene (S14). This allows an integrated lighting effect to be produced on the wall surface of the first illumination object and the wall surface of the second illumination object.

<Action and effect>
Next, the effects of the lighting control device 10, the lighting production system 1, and the lighting control method according to the present embodiment will be described.

For example, in conventional technology, one lighting scene is executed for one illumination object. In this case, when one lighting scene is executed for two adjacent illumination objects, the sizes and shapes of the two adjacent illumination objects are different from each other, so the executed lighting scenes may appear to have different sizes. This can result in a misalignment in the lighting scenes performed for the two adjacent illumination objects, making it difficult to achieve an appropriate lighting scene.

However, the lighting control device 10 of this embodiment includes a storage unit 13 that stores information about multiple lights and image content, and a processing unit 11. The information about the lights includes a background image including an object to be illuminated with light from the lighting fixtures 30, spatial information indicated by the background image, and position information of each of the multiple virtual lighting fixtures 30a arranged on the background image. The processing unit 11 also combines information about two or more lights from the information about the multiple lights into one, and generates one combined composite information (e.g., one lighting performance area). Then, based on the combined information and the image content, the processing unit 11 generates, as one lighting scene, multiple lighting scenes that can be reproduced as a light performance in which two or more objects are illuminated by multiple lighting fixtures 30 corresponding to the multiple virtual lighting fixtures 30a included in the combined information.

According to this, when performing a lighting scene for multiple illumination objects, information about two or more illuminations can be combined into one by synthesizing the information about the illumination. Therefore, since one lighting scene can be reproduced using the lighting production area in which multiple illumination objects are combined into one and the image content, even if there are differences in the positions, sizes, and shapes of the multiple illumination objects, deviations are unlikely to occur in the lighting scene performed on the multiple illumination objects.

Therefore, the lighting control device 10 can perform a single lighting scene on multiple illumination objects. As a result, the user is less likely to feel uncomfortable when a unified lighting scene is performed on multiple illumination objects.

The lighting system 1 of this embodiment also includes a lighting control device 10 and a plurality of lighting fixtures 30 that are installed on a plurality of illumination objects and irradiate the illumination objects with light.

This lighting control method also provides the same effects as described above.

In addition, in the lighting control method of this embodiment, information on multiple lights and image content are stored, and the information on the lights includes a background image including an object to be illuminated by the light of the lighting fixtures 30, spatial information indicated by the background image, and position information of each of the multiple virtual lighting fixtures 30a arranged on the background image. Information on two or more lights among the information on the multiple lights is synthesized into one, and synthesized information is generated. Based on the synthesized information and the image content, multiple lighting scenes that can be reproduced as a light performance in which two or more objects are illuminated by multiple lighting fixtures 30 corresponding to the multiple virtual lighting fixtures 30a included in the synthesized information are generated as one lighting scene.

This lighting control method also provides the same effects as described above.

In addition, in the lighting control device 10 of this embodiment, the processing unit 11 standardizes the size of the lighting scene, which is the light performance irradiated on multiple illumination objects, based on the spatial information in the information about the multiple illuminations. Then, the processing unit 11 combines the information about the multiple illuminations into one to generate combined information.

This allows the size of the lighting scene, which is the light performance irradiated on multiple illumination objects, to be unified. In other words, by increasing or decreasing the size of the lighting scene, the size of the lighting scene performed on all illumination objects can be made the same. This makes it possible to perform a performance using a single lighting scene without causing any discomfort to the user.

In addition, in the lighting control device 10 of this embodiment, the processing unit 11 standardizes the size of the lighting scene, which is a light performance that is irradiated onto multiple illumination objects, based on the spatial information in the information about one of the multiple illuminations. Then, the processing unit 11 combines the information about the multiple illuminations into one to generate combined information.

By setting spatial information in the information about one reference lighting, it is possible to unify the size of the lighting scenes to be performed on other illuminated objects. In other words, by increasing or decreasing the size of the lighting scene, it is possible to make the size of the lighting scenes performed on all illuminated objects the same. This makes it possible to perform a performance using one lighting scene without causing discomfort to the user.
