[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. Note that each of the embodiments described below shows a specific example of the present disclosure. Therefore, the numerical values, shapes, materials, components, arrangement and connection of the components, steps, order of steps, and the like shown in the following embodiments are merely examples and are not intended to limit the present disclosure.

[0012] Each figure is a schematic diagram and is not necessarily precisely illustrated. Therefore, for example, the scales and the like do not necessarily match in each figure. Furthermore, in each figure, the same reference numerals are given to substantially the same configurations, and duplicated explanations are omitted or simplified.

[0013] (Embodiment) <Configuration and Function: Lighting System 1> A lighting production system 1 according to the following embodiment will be described.

[0014] FIG. 1 is a block diagram showing a lighting production system 1 according to an embodiment.

[0015] As shown in FIG. 1, the lighting production system 1 is a lighting production system that can make the lighting fixtures 30 arranged on multiple illumination objects 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 a dimming rate for each pixel included in the image content, a color adjustment rate for each pixel included in the image content, and a fade time. The illumination object is a non-transparent object that can emit light, such as a building such as a building or a house, a road surface, or a banner.

[0016] The 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 a plurality of illumination targets based on information indicating a lighting scene, it is possible to reflect the change in pixel color over time in the emission color of lighting device 30 by generating information indicating a lighting scene according to the change in pixel color over time. For example, when the image content is a content that expresses the movement of a polka dot pattern, the change in color according to the movement of the polka dot pattern corresponding to a specific pixel in the image content is reflected in the emission color of lighting device 30. In addition, the image content is not limited to an image of a polka dot pattern, and may be an image of clouds, fireworks, a fountain, a rainbow, an aurora, or the like.

[0017] At this time, each of the multiple lighting devices 30 is associated with a pixel of the image content.

[0018] Fig. 2 is a diagram showing an example of the correspondence between a plurality of lighting fixtures 30 and image content. In Fig. 2, two buildings arranged adjacent to each other are illustrated as a plurality of irradiation objects. In this embodiment, one of the two irradiation objects may be referred to as a first irradiation object, and the other of the two irradiation objects may be referred to as a second irradiation object.

[0019] 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. Also, the ranges R1a and R2a are of the same size, and the ranges R1b and R2b are of the same size.

[0020] Here, the illumination area is the maximum area that can be illuminated on an illumination target by a plurality of lighting devices 30. Moreover, the performance area is the area of ​​light illuminated on an illumination target by one or more lighting devices 30.

[0021] In addition, the range R1b specified for the image content is associated with the rendering area R1d of the outer wall of the first irradiation object, and the range R2b specified for the image content is associated with the rendering area R2d of the outer wall of the second irradiation object. Note that since the rendering area R1d is larger than the irradiation area R1, the lighting scene is not executed in the part of the rendering area R1d that extends beyond the irradiation area R1 (the area of ​​the rendering area R1d excluding the irradiation area R1) because no lighting fixtures 30 exist. The irradiation area R1 and the irradiation area R2 are defined by the coordinates of the spatial information.

[0022] In this way, each lighting device 30 is associated with a pixel of the image content and emits light of the same color as that pixel.

[0023] In such a lighting design system 1, as shown in FIGS. 1 and 2, a lighting control device 10 can link a plurality of lighting fixtures 30 to perform a lighting design.

[0024] The lighting production system 1 includes a plurality of lighting fixtures 30 and a processing terminal 2.

[0025] [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.

[0026] In addition, when the exterior walls of the first and second irradiation objects are viewed from a predetermined point along a direction perpendicular to the arrangement direction of the first and second irradiation objects, the lighting fixtures 30 are installed on the exterior walls facing the predetermined point. Therefore, the lighting fixtures 30 form one lighting performance area consisting of at least the exterior walls of the first and second irradiation objects that are adjacent to each other. The lighting performance area is an area in which light can be irradiated onto these exterior walls by the lighting fixtures 30, and is the sum of the performance area of ​​the first and second irradiation objects.

[0027] Each of the lighting devices 30 has a dimming control function and a color adjustment control function. By acquiring information indicating a lighting scene from the lighting control device 10, each of the lighting devices 30 executes a dimming control function and a color adjustment control function in accordance with the information indicating the lighting scene.

[0028] Each of the lighting devices 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 in accordance with 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 devices 30 may 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.

[0029] Each of the red light source, green light source, and blue light source is realized by an LED (Light Emitting Diode) chip or the like, and the light emission brightness of each light source can be controlled independently, thereby enabling the change of the light emission color of the lighting device 30. 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.

[0030] [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.

[0031] Specifically, the processing terminal 2 includes a lighting control device 10 and a display device 15.

[0032] By transmitting information indicating a lighting scene to each of the plurality of lighting fixtures 30, the lighting control device 10 can cause the plurality of lighting fixtures 30 to act out the lighting scene indicated in the information. In other words, the lighting production system 1 can act out a lighting scene for a plurality of illumination targets by changing the dimming rate and / or color adjustment rate of the light emitted from each of the plurality of 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.

[0033] The lighting control device 10 includes a storage unit 13, a processing unit 11, and a display control unit 12.

[0034] The storage unit 13 stores information about a plurality of lighting fixtures and image content. In the present embodiment, the storage unit 13 stores one or more image contents. The information about the lighting fixtures includes a background image including an illumination target illuminated with light from the plurality of lighting fixtures 30, spatial information indicated by the background image, and position information about each of the plurality of virtual lighting fixtures 30a arranged on the background image.

[0035] Furthermore, the processing terminal 2 may acquire a background image, image content, and the like from a distribution server, so that the background image, image content, and the like may be stored in the storage unit 13.

[0036] The background image is an image including an illumination object on which light from the lighting fixtures 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. Also, the background image may be composed of only illumination objects.

[0037] The spatial information is set according to each background image as shown in Fig. 3A. Fig. 3A is a diagram showing spatial information and a background image. The spatial information is, for example, information indicating three-dimensional coordinates that define the position of the irradiation object in the background image, the size (length, width, height) of the irradiation object, the shape of the irradiation object, etc., the size of the irradiation area, the position of the irradiation area, the shape of the irradiation area, etc.

[0038] The position information is information indicating the position coordinates of the virtual lighting fixture 30a arranged 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 linked to an ID for identifying 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-related information includes information on the size of the light emission surface of the lighting fixture 30, information on the light emission direction of the lighting fixture 30, and the like, and these pieces of information may be linked to the position information.

[0039] The storage unit 13 includes, for example, a primary storage device such as a random access memory (RAM) and a read only memory (ROM). The storage unit 13 may also include a secondary storage device such as a hard disk drive (HDD) and a solid state drive (SSD), and a tertiary storage device such as an SD card.

[0040] 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 illuminations. Then, the processing unit 11 synthesizes information on two or more illuminations among the information on the multiple illuminations into one. For example, the processing unit 11 synthesizes information on the illumination on the first irradiation object and information on the illumination 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, the synthesis is to unify the size of multiple spatial information to consolidate them into one spatial information. Specifically, the synthesis is to unify the size of the performance area of ​​the first irradiation object and the size of the performance area of ​​the second irradiation object, as shown in FIG. 4A and FIG. 4B, and to form one pseudo performance area, that is, one lighting performance area, by synthesizing the two. FIG. 4A is a diagram showing the irradiation area R1 and the performance area R1c of the first irradiation object and the irradiation area R2 and the performance area R2c of the second irradiation object in the virtual space. FIG. 4B is another diagram showing the irradiation area R1 and the performance area R1d of the first irradiation object, and the irradiation area R2 and the performance area R2d of the second irradiation object in the virtual space.

[0041] 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 sizes of the lighting scenes to be performed on both outer walls are adjusted to unify the sizes of the lighting scenes. Here, the size of the lighting scene is the size of the performance area.

[0042] Therefore, in the image content superimposed on the combined lighting information (composite information) by 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.

[0043] Furthermore, the processing unit 11 may unify the size of a lighting scene, which is a performance of light irradiated onto a plurality of illumination targets, based on spatial information in information on one of the plurality of illuminations.

[0044] 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 to unify 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 a 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 a reference.

[0045] Even in this case, in the image content that 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.

[0046] Furthermore, the processing unit 11 generates, based on the synthesis information and the image content, a plurality of lighting scenes that can be reproduced as a single lighting scene by illuminating two or more illumination objects with a plurality of lighting devices 30 corresponding to a plurality of virtual lighting devices 30a included in the synthesis information. That is, 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.

[0047] FIG. 5 is a diagram showing the processing terminal 2 and the display device 15 of the processing terminal 2, as well as a diagram showing a background image and a plurality of virtual lighting fixtures 30a displayed on the display device 15. As shown in FIG.

[0048] 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. In addition, the display control unit 12 can add an image simulating a lighting scene to the composite information and display it.

[0049] 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 display an image simulating an illumination scene using the plurality of virtual lighting fixtures 30a arranged in the background image by executing the generated information related to illumination.

[0050] [Processing Operation] Next, the processing operations of the lighting control device 10, the lighting production system 1, and the lighting control method according to the present embodiment will be described.

[0051] FIG. 6 is a flowchart showing the processing operation of the lighting production system 1 according to the embodiment.

[0052] The user starts the lighting effect creation tool by operating the processing terminal 2. The user selects a background image including the first irradiation object and a background image including the second irradiation object stored in the storage unit 13. As a result, the background image including the first irradiation object and the background image including the second irradiation object are displayed on the display screen 15a of the display device 15.

[0053] 6, a 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 the multiple virtual lighting fixtures 30a are placed on the background image (S11). At this time, the processing unit 11 places the multiple virtual lighting fixtures 30a at position coordinates in a virtual space that mimics the background image. Then, the processing unit 11 associates the position coordinates of the virtual lighting fixtures 30a placed in the background image with the IDs of the virtual lighting fixtures 30a.

[0054] Next, the processing unit 11 generates composite information by synthesizing information about two or more lights among the information about the lights in the virtual space displayed on the display screen 15a (S12).

[0055] Specifically, when creating an illumination scene for a first illumination object and a second illumination object, processing unit 11 combines information regarding the illumination on the first illumination object (referred to as information regarding the first illumination) with information regarding the illumination on the second illumination object (referred to as information regarding the second illumination).

[0056] For example, when the information on the first lighting and the information on the second lighting are combined, the size of the performance area R2c of the second lighting object shown in the information on 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 on lighting indicating the combined lighting performance areas R1c and R2c. The combined lighting performance areas R1c and R2c are the size of the image content represented on the outer wall of the first lighting object and the outer wall of the second lighting object adjacent to each other by the lighting scene.

[0057] 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 illumination scene is not executed in the part of the illumination area R2 that is beyond the performance area R2c.

[0058] In addition, when the second illumination object shown in the information on the second illumination is used as a reference, the size of the performance area R1d of the first illumination object shown in the information on the first illumination is changed to match the size of the illumination area R2 of the second illumination object, thereby unifying the two sizes. In other words, the size of the performance area R1d of the first illumination object is set large so that it is the same size as the illumination area R2 of the outer wall of the second illumination object. In this way, the processing unit 11 generates information on illumination indicating the combined illumination performance areas R1d and R2d.

[0059] 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 is outside the illumination area R1, the lighting device 30 does not exist, and therefore the lighting scene is not executed.

[0060] 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, that is, on a lighting production area composited into one, in a virtual space simulating a 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).

[0061] Next, information indicating the lighting scene generated by the lighting control device 10 is transmitted to the multiple lighting fixtures 30, and the multiple lighting fixtures 30 execute the information indicating the lighting scene (S14).This makes it possible to create an integrated light effect on the wall surface of the first illumination object and the wall surface of the second illumination object.

[0062] <Action and effect> Next, the effects of the lighting control device 10, lighting production system 1, and lighting control method in the present embodiment will be described.

[0063] For example, in the 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. Therefore, there may be a misalignment between the lighting scenes executed for the two adjacent illumination objects, making it difficult to realize an appropriate lighting scene.

[0064] However, the lighting control device 10 of the present embodiment includes a storage unit 13 that stores information about a plurality of lighting fixtures and image content, and a processing unit 11. The information about the lighting fixtures includes a background image including an illumination target illuminated by the light from the lighting fixtures 30, spatial information indicated by the background image, and position information of each of the plurality of virtual lighting fixtures 30a arranged on the background image. The processing unit 11 also synthesizes information about two or more lighting fixtures among the information about the plurality of lighting fixtures into one, and generates one synthesized information (e.g., one lighting performance area). Then, the processing unit 11 generates, based on the synthesis information and the image content, a plurality of lighting scenes that can be reproduced as a light performance in which two or more illumination targets are illuminated by the plurality of lighting fixtures 30 corresponding to the plurality of virtual lighting fixtures 30a included in the synthesis information, as one lighting scene.

[0065] According to this, when performing a lighting scene for multiple illumination objects, information on two or more illuminations can be combined into one by synthesizing information on the illuminations. Therefore, one lighting scene can be reproduced using the lighting production area in which multiple illumination objects are combined into one and the image content, so that even if there are differences in the positions, sizes, and shapes of the multiple illumination objects, the lighting scenes performed on the multiple illumination objects are unlikely to be misaligned.

[0066] Therefore, the lighting control device 10 can perform a single lighting scene on a plurality of illumination objects. As a result, the user is less likely to feel uncomfortable when a unified lighting scene is performed on a plurality of illumination objects.

[0067] The lighting production system 1 of the present embodiment includes a lighting control device 10 and a plurality of lighting fixtures 30 that are installed at a plurality of illumination objects, respectively, and irradiate the illumination objects with light.

[0068] This lighting control method also provides the same effects as those described above.

[0069] In addition, in the lighting control method of the present embodiment, information on a plurality of lights and image content are stored, the information on 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 for each of a plurality of virtual lighting fixtures 30a arranged on the background image, information on two or more lights among the information on the plurality of lights is synthesized into one, and synthetic information is generated. Based on the synthetic information and the image content, a plurality of lighting scenes that can be reproduced as a light performance in which two or more objects are illuminated by a plurality of lighting fixtures 30 corresponding to the plurality of virtual lighting fixtures 30a included in the synthetic information are generated as one lighting scene.

[0070] This lighting control method also provides the same effects as those described above.

[0071] In addition, in the lighting control device 10 of the present embodiment, the processing unit 11 unifies the size of a lighting scene, which is a performance of light irradiated on a plurality of illumination objects, based on spatial information in the information on the plurality of illuminations. Then, the processing unit 11 synthesizes the information on the plurality of illuminations into one to generate synthesized information.

[0072] According to this, it is possible to unify the size of the lighting scene, which is the light performance irradiated on a plurality of irradiation objects. In other words, by increasing or decreasing the size of the lighting scene, it is possible to make the size of the lighting scene performed on all irradiation objects the same. Therefore, it is possible to perform a performance using one lighting scene without causing a sense of incongruity to the user.

[0073] In addition, in the lighting control device 10 of the present embodiment, the processing unit 11 standardizes the size of a lighting scene, which is a performance of light irradiated onto multiple illumination objects, based on spatial information in the information on one of the multiple illuminations. Then, the processing unit 11 synthesizes the information on the multiple illuminations into one to generate synthesized information.

[0074] According to this, by setting the spatial information in the information on one reference lighting, the size of the lighting scene to be performed on the other illumination objects can be unified. In other words, by increasing or decreasing the size of the lighting scene, the size of the lighting scene to be performed on all illumination objects can be made the same. Therefore, it is possible to perform a performance using one lighting scene without causing a sense of incongruity to the user.

[0075] (Other variations, etc.) Although the present disclosure has been described above based on the embodiments, the present disclosure is not limited to these embodiments.

[0076] For example, the lighting control device, the lighting production system, and the lighting control method according to the present embodiment may be realized on a cloud server.

[0077] The processing unit and the lighting control unit included in the lighting control device and the lighting production system in the present embodiment are typically realized as an LSI, which is an integrated circuit. These may be individually implemented as single chips, or may be integrated in part or in whole as a single chip.

[0078] The integrated circuit is not limited to an LSI, but may be realized by a dedicated circuit or a general-purpose processor. A field programmable gate array (FPGA) that can be programmed after the LSI is manufactured, or a reconfigurable processor that can reconfigure the connections and settings of the circuit cells inside the LSI may also be used.

[0079] In the above embodiment, each component may be implemented by dedicated hardware or by executing a software program suitable for each component. Each component may be implemented by a program execution unit such as a CPU or processor reading and executing a software program recorded on a storage medium such as a hard disk or semiconductor memory.

Furthermore, the functions of multiple functional blocks having similar functions may be processed in parallel or in a time-sharing manner by a single piece of hardware or software.
