　（実施の形態）
　＜構成及び機能：照明演出システム１＞
　以下の実施の形態に係る照明演出システム１について説明する。 (Embodiment)
<Structure and function: lighting production system 1>
A lighting effect system 1 according to the following embodiment will be described.
　図１は、実施の形態に係る照明演出システム１を示すブロック図である。 FIG. 1 is a block diagram showing a lighting production system 1 according to an embodiment.
　図１に示すように、照明演出システム１は、複数の照射対象物に配置された照明器具３０を、画像コンテンツに含まれる特定の画素と同じ色で発光させることができる照明演出用のシステムである。照明演出システム１は、画像コンテンツに応じた照明シーンを示す情報を用いることで、複数の照射対象物が一体的となった照明シーンを実演することができる。ここで、照明シーンを示す情報は、画像コンテンツに含まれる画素ごとの調光率、画像コンテンツに含まれる画素ごとの調色率、及び、フェード時間等の照明器具３０を制御するための情報を含む。また、照射対象物は、ビル又は住宅等の建物、路面、垂れ幕等の光を照射することができる非透明の物体である。 As shown in FIG. 1, a lighting effect system 1 is a lighting effect system that can cause lighting fixtures 30 arranged on a plurality of irradiation objects to emit light in the same color as specific pixels included in image content. be. The lighting effect system 1 can demonstrate a lighting scene in which a plurality of irradiation targets are integrated by using information indicating a lighting scene according to image content. Here, the information indicating the lighting scene includes the dimming rate for each pixel included in the image content, the toning rate for each pixel included in the image content, and information for controlling the lighting fixture 30 such as fade time. include. The object to be irradiated is a non-transparent object that can be irradiated with light, such as a building or a house, a road surface, a banner, or the like.
　画像コンテンツは、特定の画素の色が一定の静止画コンテンツ、特定の画素の色が経時的に変化する動画コンテンツを含む。このため、照明演出システム１は、照明シーンを示す情報に基づいて複数の照射対象物に光の演出を行う場合、画素の色の経時的変化に応じた照明シーンを示す情報を生成することで、画素の色の経時的変化を照明器具３０の発光色に反映させることができる。例えば、画像コンテンツが水玉模様の動きを表現したコンテンツである場合、画像コンテンツにおける特定の画素に対応した水玉模様の動きに応じた色の変化が照明器具３０の発光色に反映される。また、画像コンテンツは、水玉模様の映像に限られず、雲、花火、噴水、虹又はオーロラ等の映像であってもよい。 Image content includes still image content in which specific pixel colors are constant, and video content in which specific pixel colors change over time. For this reason, when the lighting effect system 1 performs light effects on a plurality of irradiation targets based on information indicating a lighting scene, the lighting effect system 1 can generate information indicating a lighting scene according to a change in pixel color over time. , the temporal change in the color of the pixels can be reflected in the color of light emitted from the lighting device 30 . For example, if the image content expresses the movement of a polka dot pattern, the luminous color of the lighting device 30 reflects the change in color according to the movement of the polka dot pattern corresponding to a specific pixel in the image content. Also, the image content is not limited to images of polka dots, and may be images of clouds, fireworks, fountains, rainbows, aurora, or the like.
　このとき、複数の照明器具３０のそれぞれは、画像コンテンツの画素に対応付けられる。 At this time, each of the plurality of lighting fixtures 30 is associated with a pixel of the image content.
　図２は、複数の照明器具３０と、画像コンテンツとの対応関係の一例を示す図である。図２では、複数の照射対象物として、隣接して並んだ２つの建物を例示している。本実施の形態では、２つの照射対象物のうちの一方の照射対象物を第１照射対象物と呼び、２つの照射対象物のうちの他方の照射対象物を第２照射対象物と呼ぶことがある。 FIG. 2 is a diagram showing an example of correspondence relationships between a plurality of lighting fixtures 30 and image content. FIG. 2 exemplifies two adjacent buildings as a plurality of irradiation objects. In the present embodiment, one of the two irradiation targets is referred to as the first irradiation target, and the other of the two irradiation targets is referred to as the second irradiation target. There is
　図２に示すように、画像コンテンツに対して指定された範囲Ｒ１ａは、第１照射対象物の外壁の演出領域Ｒ１ｃと対応付けられ、画像コンテンツの指定された範囲Ｒ２ａは、第２照射対象物の外壁の演出領域Ｒ２ｃと対応付けられる。なお、演出領域Ｒ２ｃは照射領域Ｒ２よりも小さい領域であるため、演出領域Ｒ２ｃからはみ出た照射領域Ｒ２の部分（照射領域Ｒ２から演出領域Ｒ２ｃを除いた領域）では照明シーンが実行されず、照明器具３０が点灯しない。また、範囲Ｒ１ａと範囲Ｒ２ａとは同等の大きさであり、範囲Ｒ１ｂと範囲Ｒ２ｂとは同等の大きさである。 As shown in FIG. 2, the range R1a specified for the image content is associated with the rendering region R1c of the outer wall of the first irradiation target, and the specified range R2a for the image content is associated with the second irradiation target. is associated with the effect area R2c on the outer wall of the . Since the effect region R2c is smaller than the irradiation region R2, the illumination scene is not executed in the portion of the irradiation region R2 protruding from the effect region R2c (the region obtained by excluding the effect region R2c from the irradiation region R2). Appliance 30 does not light up. Further, the range R1a and the range R2a have the same size, and the range R1b and the range R2b have the same size.
　ここで、照射領域とは、複数の照明器具３０が照射対象物に照射可能な最大領域である。また、演出領域とは、１以上の照明器具３０が照射対象物に照射された光の領域である。 Here, the irradiation area is the maximum area that can be irradiated on the irradiation object by the plurality of lighting fixtures 30 . Also, the rendering area is an area of light emitted from one or more lighting fixtures 30 to an irradiation target.
　また、画像コンテンツに対して指定された範囲Ｒ１ｂは、第１照射対象物の外壁の演出領域Ｒ１ｄと対応付けられ、画像コンテンツの指定された範囲Ｒ２ｂは、第２照射対象物の外壁の演出領域Ｒ２ｄと対応付けられる。なお、演出領域Ｒ１ｄは照射領域Ｒ１よりも大きい領域であるため、照射領域Ｒ１からはみ出た演出領域Ｒ１ｄの部分（演出領域Ｒ１ｄから照射領域Ｒ１を除いた領域）では照明器具３０が存在しないため照明シーンが実行されない。照射領域Ｒ１及び照射領域Ｒ２は、空間情報の座標によって規定される。 Further, the range R1b designated for the image content is associated with the rendering region R1d of the outer wall of the first irradiation target, and the designated range R2b of the image content is related to the rendering region R1d of the outer wall of the second irradiation target. It is associated with R2d. Note that since the rendering region R1d is a region larger than the irradiation region R1, the lighting device 30 does not exist in the portion of the rendering region R1d protruding from the irradiation region R1 (the region obtained by excluding the irradiation region R1 from the rendering region R1d). Scene does not run. The irradiation area R1 and the irradiation area R2 are defined by the coordinates of the spatial information.
　このように、それぞれの照明器具３０は、画像コンテンツの画素と対応付けられることで、当該画素と同じ色で発光する。 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.
　このような照明演出システム１では、図１及び図２に示すように、照明制御装置１０が複数の照明器具３０を連動させて照明演出を行うことができる。 In such a lighting production system 1, as shown in FIGS. 1 and 2, the lighting control device 10 can interlock a plurality of lighting fixtures 30 to produce a lighting production.
　照明演出システム１は、複数の照明器具３０と、処理端末２とを備えている。 The lighting production system 1 includes a plurality of lighting fixtures 30 and a processing terminal 2.
　［照明器具３０］
　複数の照明器具３０は、複数の照射対象物のそれぞれに設置され、複数の照射対象物に対して光を照射する。具体的には、複数の照明器具３０は、設置されている照射対象物の外壁に対して光を照射することが可能なように、複数の照明器具３０が照射対象物の外壁に設置されている。図２では、第１照射対象物及び第２照射対象物のそれぞれに複数の照明器具３０が設置されている。 [Lighting equipment 30]
A plurality of lighting fixtures 30 are installed on each of the plurality of irradiation targets, and irradiate the plurality of irradiation targets with light. Specifically, the plurality of lighting fixtures 30 are installed on the outer wall of the irradiation target so that the lighting fixtures 30 can irradiate the outer wall of the irradiation target. there is In FIG. 2, a plurality of lighting fixtures 30 are installed on each of the first irradiation object and the second irradiation object.
　また、第１照射対象物及び第２照射対象物の並び方向と直交する方向に沿って第１照射対象物及び第２照射対象物の外壁を所定地点から見た場合、複数の照明器具３０は、所定地点に面する外壁に設置されている。このため、複数の照明器具３０は、少なくとも隣り合う２つの第１照射対象物の外壁及び第２照射対象物の外壁で構成される１つの照明演出領域を形成する。照明演出領域は、複数の照明器具３０によってこれらの外壁に光が照射できる領域であり、第１照射対象物の演出領域と第２照射対象物の演出領域との合計の領域である。 Further, when the outer walls of the first irradiation target and the second irradiation target are viewed from a predetermined point along the direction perpendicular to the arrangement direction of the first irradiation target and the second irradiation target, the plurality of lighting fixtures 30 , installed on the outer wall facing a predetermined point. For this reason, the plurality of lighting fixtures 30 form one illumination rendering area composed of at least two adjacent outer walls of the first irradiation object and the outer walls of the second irradiation object. The lighting effect area is an area in which these outer walls can be irradiated with light from the plurality of lighting fixtures 30, and is the total area of the effect area of the first irradiation object and the effect area of the second irradiation object.
　複数の照明器具３０のそれぞれは、調光制御機能及び調色制御機能を有している。複数の照明器具３０のそれぞれは、照明制御装置１０から照明シーンを示す情報を取得することで、照明シーンを示す情報に応じた調光制御機能及び調色制御機能を実行する。 Each of the plurality of lighting fixtures 30 has a dimming control function and a toning control function. Each of the plurality of lighting fixtures 30 acquires the information indicating the lighting scene from the lighting control device 10, and executes the light adjustment control function and the color adjustment control function according to the information indicating the lighting scene.
　複数の照明器具３０のそれぞれは、赤色光源、緑色光源、及び、青色光源を有している。赤色光源、緑色光源、及び、青色光源は、発光色と発光色それぞれに対する発光輝度とが指定された照明シーンを示す情報に応じて発光する。なお、複数の照明器具３０のそれぞれは、赤色光源、緑色光源、及び、青色光源に加えて、白色光源又は黄色光源を備えてもよい。 Each of the multiple 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 the information indicating the lighting scene in which the emission color and the emission luminance for each emission color are specified. Note that each of the plurality of lighting fixtures 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.
　また、赤色光源、緑色光源、及び、青色光源のそれぞれは、ＬＥＤ（Ｌｉｇｈｔ　Ｅｍｉｔｔｉｎｇ　Ｄｉｏｄｅ）チップなどによって実現され、各光源の発光輝度は独立して制御可能である。これにより、照明器具３０の発光色の変更が実現される。なお、赤色光源、緑色光源、及び、青色光源のそれぞれは、半導体レーザ等の半導体発光素子、有機ＥＬ（Ｅｌｅｃｔｒｏ　Ｌｕｍｉｎｅｓｃｅｎｃｅ）又は無機ＥＬ等の固体発光素子を用いた発光モジュールによって実現されてもよい。 Also, each of the red light source, the green light source, and the blue light source is realized by an LED (Light Emitting Diode) chip or the like, and the emission brightness of each light source can be controlled independently. Thereby, the change of the luminescent color of the lighting fixture 30 is implement|achieved. Each of the red light source, the green light source, and the blue light source may be realized by a light emitting module using a semiconductor light emitting device such as a semiconductor laser, or a solid state light emitting device such as organic EL (Electro Luminescence) or inorganic EL.
　［処理端末２］
　処理端末２は、ユーザが操作する操作端末であり、パーソナルコンピュータ、スマートフォン等である。ユーザは、処理端末２を用いることで、照明シーンを示す情報を生成する。 [Processing terminal 2]
The processing terminal 2 is an operation terminal operated by a user, such as a personal computer or a smart phone. A user uses the processing terminal 2 to generate information indicating a lighting scene.
　具体的には、処理端末２は、照明制御装置１０と、表示装置１５とを有している。 Specifically, the processing terminal 2 has a lighting control device 10 and a display device 15 .
　照明制御装置１０は、複数の照明器具３０のそれぞれに対して照明シーンを示す情報を送信することで、当該情報に示される照明シーンを複数の照明器具３０に実演させることができる。つまり、照明演出システム１は、照明シーンを示す情報に基づいて、複数の照明器具３０のそれぞれから出射される光の調光率及び／又は調色率を経時的に変化させたり、調光率及び／又は調色率を一定にさせたりすることで、複数の照射対象物に対して照明シーンを実演することができる。 By transmitting information indicating a lighting scene to each of the plurality of lighting fixtures 30, the lighting control device 10 can cause the lighting fixtures 30 to demonstrate the lighting scene indicated by the information. That is, the lighting production system 1 changes over time the dimming rate and/or the toning rate of the light emitted from each of the plurality of lighting fixtures 30 based on the information indicating the lighting scene, or changes the dimming rate And/or by setting the toning rate constant, lighting scenes can be demonstrated for a plurality of irradiation objects.
　照明制御装置１０は、記憶部１３と、処理部１１と、表示制御部１２とを備えている。 The lighting control device 10 includes a storage section 13 , a processing section 11 and a display control section 12 .
　記憶部１３は、複数の照明に関する情報と、画像コンテンツとを記憶している。また、本実施の形態では、記憶部１３は、１以上の画像コンテンツを記憶している。照明に関する情報は、複数の照明器具３０の光が照射される照射対象物を含んだ背景画像と、背景画像が示す空間情報と、背景画像上に配置されている複数の仮想の照明器具３０ａのそれぞれの位置情報とを含む。 The storage unit 13 stores information about a plurality of lights and image content. Moreover, in this embodiment, the storage unit 13 stores one or more image contents. The lighting information includes a background image including an illumination target illuminated by light from a plurality of lighting fixtures 30, spatial information indicated by the background image, and virtual lighting fixtures 30a arranged on the background image. each location information.
　また、記憶部１３には、処理端末２が配信サーバから背景画像、画像コンテンツ等を取得することで、背景画像、画像コンテンツ等が保存されてもよい。 In addition, the background image, the image content, etc. may be stored in the storage unit 13 by the processing terminal 2 acquiring the background image, the image content, etc. from the distribution server.
　背景画像は、照明器具３０の光が照射される照射対象物を含んだ画像、つまり、照明シーンが行われる照射対象物を含んだ画像である。背景画像には、複数の照射対象物が含まれていてもよい。また、背景画像は、照射対象物のみで構成されていてもよい。 A background image is an image containing an irradiation target illuminated by the light of the lighting device 30, that is, an image containing an irradiation target on which an illumination scene is performed. A background image may include a plurality of irradiation targets. Also, the background image may consist of only the irradiation target.
　空間情報は、図３Ａに示すように、それぞれの背景画像に応じて設定されている。図３Ａは、空間情報及び背景画像を示す図である。空間情報は、例えば、背景画像における照射対象物の位置、照射対象物の大きさ（縦、横、高さ）及び照射対象物の形状等を規定する三次元的な座標、照射領域の大きさ、照射領域の位置、照射領域の形状等を規定する三次元的な座標を示す情報である。 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. Spatial information includes, for example, three-dimensional coordinates that define the position of the irradiation target in the background image, the size (length, width, height) of the irradiation target, the shape of the irradiation target, and the size of the irradiation area. , the position of the irradiation area, the information indicating the three-dimensional coordinates that define the shape of the irradiation area, and the like.
　位置情報は、図３Ｂに示すように、背景画像上の照射対象物に配置されている仮想の照明器具３０ａの位置座標を示す情報である。つまり、位置情報は、空間情報における位置座標を示す情報である。図３Ｂは、仮想の照明器具３０ａの位置情報及び仮想の照明器具３０ａのＩＤを示す図である。また、位置情報には、それぞれの仮想の照明器具３０ａを識別するＩＤが紐付けられている。仮想の照明器具３０ａのＩＤは、実際の照明器具３０のＩＤと対応している。また、照明に関する情報には、照明器具３０の光の出射面の大きさ、照明器具３０の光の出射方向に関する情報等が含まれ、これら情報が位置情報に紐づけられていてもよい。 The positional information is, as shown in FIG. 3B, information indicating the positional coordinates of the virtual lighting fixture 30a arranged on the irradiation target on the background image. That is, the position information is information indicating position coordinates in 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. Further, the position information is associated with an ID that identifies each virtual lighting fixture 30a. The ID of the virtual lighting fixture 30 a corresponds to the ID of the actual lighting fixture 30 . The information about lighting includes information about the size of the light emitting surface of the lighting fixture 30, information about the light emitting direction of the lighting fixture 30, and the like, and this information may be linked to the position information.
　記憶部１３は、例えば、ＲＡＭ（Ｒａｎｄｏｍ　Ａｃｃｅｓｓ　Ｍｅｍｏｒｙ）及びＲＯＭ（Ｒｅａｄ　Ｏｎｌｙ　Ｍｅｍｏｒｙ）等の一次記憶装置を含む。また、記憶部１３は、ＨＤＤ（Ｈａｒｄ　Ｄｉｓｋ　Ｄｒｉｖｅ）、ＳＳＤ（Ｓｏｌｉｄ　Ｓｔａｔｅ　Ｄｒｉｖｅ）等の二次記憶装置、ＳＤカード等の三次記憶装置を含んでいてもよい。 The storage unit 13 includes, for example, primary storage devices such as RAM (Random Access Memory) and 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), or a tertiary storage device such as an SD card.
　処理部１１は、複数の照明に関する情報における空間情報に基づいて、複数の照射対象物に対して照射する光の演出である照明シーンの大きさを統一する。そして、処理部１１は、複数の照明に関する情報のうちの２以上の照明に関する情報を１つに合成する。例えば、処理部１１は、第１照射対象物における照明に関する情報と、第２照射対象物における照明に関する情報とを１つに合成する。処理部１１が照明シーンの大きさを統一する場合、背景画像を模した仮想空間内でシミュレートする。ここで、合成とは、複数の空間情報の大きさを統一させることで、１つの空間情報に纏めることである。具体的には、合成とは、図４Ａ及び図４Ｂに示すように、第１照射対象物の演出領域の大きさと、第２照射対象物の演出領域の大きさとを統一して、この２つを合成することで、疑似的に１つの演出領域、つまり１つの照明演出領域を形成することである。図４Ａは、仮想空間における第１照射対象物の照射領域Ｒ１及び演出領域Ｒ１ｃと、第２照射対象物の照射領域Ｒ２及び演出領域Ｒ２ｃとを示す図である。図４Ｂは、仮想空間における第１照射対象物の照射領域Ｒ１及び演出領域Ｒ１ｄと、第２照射対象物の照射領域Ｒ２及び演出領域Ｒ２ｄとを示す別の図である。 The processing unit 11 unifies the size of the illumination scene, which is the effect of the light emitted to the plurality of illumination targets, based on the spatial information in the information on the plurality of illuminations. Then, the processing unit 11 synthesizes two or more illumination-related information among the plurality of illumination-related information into one. For example, the processing unit 11 synthesizes the information regarding the illumination of the first irradiation object and the information regarding the illumination of the second irradiation object into one. When the processing unit 11 unifies the size of the illumination scene, the simulation is performed in a virtual space simulating a background image. Here, combining means to unify the size of a plurality of pieces of spatial information to combine them into one piece of spatial information. Specifically, as shown in FIGS. 4A and 4B, synthesis means unifying the size of the rendering area of the first irradiation target and the size of the rendering area of the second irradiation target, and combining the two. By synthesizing , a pseudo one rendering area, that is, one lighting rendering area is formed. FIG. 4A is a diagram showing the irradiation region R1 and the effect region R1c of the first irradiation object and the irradiation region R2 and the effect region R2c of the second irradiation object in the virtual space. FIG. 4B is another diagram showing the irradiation region R1 and the rendering region R1d of the first irradiation object and the irradiation region R2 and the rendering region R2d of the second irradiation object in the virtual space.
　例えば、第１照射対象物の外壁に実演する照明シーンの大きさと、第２照射対象物の外壁に実演する照明シーンの大きさとを調節する場合、両方の外壁に実演する照明シーンの大きさを調節することで、照明シーンの大きさを統一する。ここで、照明シーンの大きさとは、演出領域の大きさである。 For example, when adjusting the size of the lighting scene demonstrated on the outer wall of the first irradiation object and the size of the lighting scene demonstrated on the outer wall of the second irradiation object, the size of the lighting scene demonstrated on both outer walls is adjusted. Adjust to unify the size of the lighting scene. Here, the size of the lighting scene is the size of the rendering area.
　このため、処理部１１が１つに合成した照明に関する情報（合成情報）に重畳させた画像コンテンツにおいて、例えば、第１照射対象物に照明シーンとして表現された水玉模様の大きさと、第２照射対象物に照明シーンとして表現された水玉模様の大きさとが同様の大きさとなる。 For this reason, in the image content superimposed on the illumination-related information (synthesis information) synthesized by the processing unit 11, for example, the size of the polka dot pattern expressed as the illumination scene on the first irradiation object and the size of the polka dot pattern expressed as the illumination scene on the first irradiation object The size is the same as the size of the polka dot pattern represented as the illumination scene on the object.
　また、処理部１１は、複数の照明に関する情報のうちの１つの照明に関する情報における空間情報を基準として、複数の照射対象物に対して照射する光の演出である照明シーンの大きさを統一してもよい。 In addition, the processing unit 11 unifies the size of the lighting scene, which is the effect of the light irradiated to the plurality of irradiation objects, based on the spatial information in the information regarding one lighting among the information regarding the plurality of lighting. may
　例えば、第１照射対象物の外壁に実演する照明シーンの大きさと、第２照射対象物の外壁に実演する照明シーンの大きさとを調節する場合、いずれか一方の照明シーンの大きさを基準として他方の照明シーンの大きさを調節することで、照明シーンの大きさを統一する。例えば、図４Ａに示すように、処理部１１は、第１照射対象物の照射領域Ｒ１を基準とすると、第２照射対象物の演出領域Ｒ２ｃを照射領域Ｒ２よりも小さく設定する。また、処理部１１は、図４Ｂに示すように、第２照射対象物の照射領域Ｒ２を基準とすると、第１照射対象物の演出領域Ｒ１ｄを照射領域Ｒ１よりも大きく設定する。 For example, when adjusting the size of the lighting scene to be demonstrated on the outer wall of the first irradiation object and the size of the lighting scene to be demonstrated on the outer wall of the second irradiation object, the size of one of the lighting scenes is used as a reference. By adjusting the size of the other lighting scene, the size of the lighting scene is unified. For example, as shown in FIG. 4A, the processing unit 11 sets the rendering region R2c of the second irradiation object to be smaller than the irradiation region R2 when the irradiation region R1 of the first irradiation object is used as a reference. In addition, as shown in FIG. 4B, the processing unit 11 sets the rendering region R1d of the first irradiation object larger than the irradiation region R1 when the irradiation region R2 of the second irradiation object is used as a reference.

To generate a plurality of reproducible lighting scenes as one lighting scene. In other words, the processing unit 11 simulates the lighting scene using the synthesis information in the virtual space, thereby generating information indicating the lighting scene capable of demonstrating the desired lighting scene.

　［処理動作］
　次に、本実施の形態における照明制御装置１０、照明演出システム１及び照明制御方法の処理動作について説明する。 [Processing operation]
Next, processing operations of the lighting control device 10, the lighting effect system 1, and the lighting control method in the present embodiment will be described.
　図６は、実施の形態に係る照明演出システム１の処理動作を示すフローチャートである。 FIG. 6 is a flow chart showing processing operations of the lighting effect system 1 according to the embodiment.
　ユーザは、処理端末２を操作することで、照明演出作成ツールを起動させる。ユーザは、記憶部１３に格納されている第１照射対象物を含んだ背景画像と第２照射対象物を含んだ背景画像とを選択する。これにより、第１照射対象物を含んだ背景画像と第２照射対象物を含んだ背景画像とが表示装置１５の表示画面１５ａに表示される。 The user activates the lighting effect creation tool by operating the processing terminal 2 . The user selects the background image containing the first irradiation object and the background image containing 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 15 a of the display device 15 .
　まず、図６に示すように、ユーザが処理端末２を操作して表示画面１５ａに表示された背景画像上に複数の仮想の照明器具３０ａを配置することで、表示制御部１２は、背景画像上に複数の仮想の照明器具３０ａを配置した画像を表示装置１５に表示させる（Ｓ１１）。このとき、処理部１１は、背景画像を模した仮想空間内の位置座標に仮想の照明器具３０ａを複数配置する。そして、処理部１１は、背景画像に配置された仮想の照明器具３０ａの位置座標を仮想の照明器具３０ａのＩＤに紐付ける。 First, as shown in FIG. 6, the user operates the processing terminal 2 to place a plurality of virtual lighting fixtures 30a on the background image displayed on the display screen 15a, thereby causing the display control unit 12 to display the background image. An image in which a plurality of virtual lighting fixtures 30a are arranged is displayed on the display device 15 (S11). At this time, the processing unit 11 arranges a plurality of virtual lighting fixtures 30a at the position coordinates in the virtual space simulating the background image. Then, the processing unit 11 associates the position coordinates of the virtual lighting fixture 30a arranged in the background image with the ID of the virtual lighting fixture 30a.
　次に、処理部１１は、表示画面１５ａに表示されている仮想空間内において、照明に関する情報のうちの２以上の照明に関する情報を１つに合成して合成情報を生成する（Ｓ１２）。 Next, in the virtual space displayed on the display screen 15a, the processing unit 11 synthesizes two or more pieces of lighting-related information into one to generate combined information (S12).
　具体的には、第１照射対象物及び第２照射対象物に照明シーンを演出する場合、処理部１１は、第１照射対象物における照明に関する情報（第１照明に関する情報と呼ぶ）と、第２照射対象物における照明に関する情報（第２照明に関する情報と呼ぶ）とを合成する。 Specifically, when producing an illumination scene on the first irradiation object and the second irradiation object, the processing unit 11 generates information on the illumination of the first irradiation object (referred to as information on the first illumination), 2 Information on the illumination of the object to be irradiated (referred to as information on the second illumination) is synthesized.
　例えば、第１照明に関する情報と第２照明に関する情報とを合成する場合、第１照明に関する情報に示される第１照射対象物を基準とすると、第１照射対象物における照射領域Ｒ１の大きさに合わせて、第２照明に関する情報に示される第２照射対象物における演出領域Ｒ２ｃの大きさを変更することで、この２つの大きさを統一する。つまり、第１照射対象物の外壁の照射領域Ｒ１と同様の大きさになるように、第２照射対象物の演出領域Ｒ２ｃの大きさを小さく設定する。このようにして、処理部１１は、１つに合成した照明演出領域Ｒ１ｃ、Ｒ２ｃを示す照明に関する情報を生成する。１つに合成した照明演出領域Ｒ１ｃ、Ｒ２ｃは、照明シーンによって隣り合う２つの第１照射対象物の外壁及び第２照射対象物の外壁に表現された画像コンテンツの大きさとなる。 For example, when synthesizing the information on the first illumination and the information on the second illumination, the size of the irradiation area R1 on the first irradiation object is based on the first irradiation object indicated in the information on the first illumination. Together, these two sizes are unified by changing the size of the effect region R2c in the second irradiation object indicated in the information about the second lighting. That is, the size of the rendering region R2c of the second irradiation object is set small so that it has the same size as the irradiation region R1 of the outer wall of the first irradiation object. In this manner, the processing unit 11 generates lighting information indicating the combined lighting effect regions R1c and R2c. The combined lighting effect regions R1c and R2c have the size of the image content expressed on the outer walls of the two adjacent first and second irradiation targets according to the lighting scene.
　この場合、第２照射対象物における照射領域Ｒ２は、第１照射対象物における照射領域Ｒ１よりも大きい、つまり第２照射対象物の演出領域Ｒ２ｃよりも大きい。このため、演出領域Ｒ２ｃからはみ出た照射領域Ｒ２の部分では照明シーンが実行されない。 In this case, the irradiation region R2 of the second irradiation object is larger than the irradiation region R1 of the first irradiation object, that is, the rendering region R2c of the second irradiation object. Therefore, the lighting scene is not executed in the portion of the irradiation region R2 protruding from the rendering region R2c.
　また、第２照明に関する情報に示される第２照射対象物を基準とすると、第２照射対象物における照射領域Ｒ２の大きさに合わせて、第１照明に関する情報に示される第１照射対象物における演出領域Ｒ１ｄの大きさを変更することで、この２つの大きさを統一する。つまり、第２照射対象物の外壁の照射領域Ｒ２と同様の大きさになるように、第１照射対象物の演出領域Ｒ１ｄの大きさを大きく設定する。このようにして、処理部１１は、１つに合成した照明演出領域Ｒ１ｄ、Ｒ２ｄを示す照明に関する情報を生成する。 In addition, when the second irradiation object indicated in the information about the second illumination is used as a reference, the size of the irradiation area R2 in the second irradiation object is adjusted to the first irradiation object indicated in the information about the first illumination. These two sizes are unified by changing the size of the effect area R1d. That is, the size of the rendering region R1d of the first irradiation object is set large so that it has the same size as the irradiation region R2 of the outer wall of the second irradiation object. In this manner, the processing unit 11 generates lighting information indicating the combined lighting effect regions R1d and R2d.
　この場合、第１照射対象物における照射領域Ｒ１は、第２照射対象物における照射領域Ｒ２よりも小さい、つまり第１照射対象物の演出領域Ｒ１ｄよりも小さい。このため、照射領域Ｒ１からはみ出た演出領域Ｒ１ｄの部分では照明器具３０が存在しないため照明シーンが実行されない。 In this case, the irradiation region R1 of the first irradiation object is smaller than the irradiation region R2 of the second irradiation object, that is, the rendering region R1d of the first irradiation object. Therefore, the lighting scene is not executed in the portion of the rendering region R1d protruding from the irradiation region R1 because the lighting device 30 does not exist.
　次に、ユーザが処理端末２を操作することで所望の照明シーンを示す情報を生成する。つまり、処理部１１は、背景画像を模した仮想空間において、合成情報つまり１つに合成した照明演出領域上で照明シーンをシミュレートする。このとき、表示制御部１２は、仮想空間でシミュレートされている照明シーンを表示画面１５ａに表示する。そして、ユーザが処理端末２を操作して所望の照明シーンを設定することで、処理部１１は、照明シーンを示す情報を生成する（Ｓ１３）。 Next, the user operates the processing terminal 2 to generate information indicating the desired lighting scene. That is, the processing unit 11 simulates a lighting scene on the combined information, that is, the combined lighting effect area in a virtual space imitating 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. When the user operates the processing terminal 2 to set a desired lighting scene, the processing unit 11 generates information indicating the lighting scene (S13).
　次に、照明制御装置１０が生成した照明シーンを示す情報を複数の照明器具３０に送信することで、複数の照明器具３０は、照明シーンを示す情報を実行する（Ｓ１４）これにより、第１照射対象物の壁面と第２照射対象物の壁面とで、一体化された光の演出を行うことができる。 Next, by transmitting the information indicating the lighting scene generated by the lighting control device 10 to the plurality of lighting fixtures 30, the plurality of lighting fixtures 30 execute the information indicating the lighting scene (S14). The wall surface of the object to be irradiated and the wall surface of the second object to be irradiated can perform an integrated light effect.
　＜作用効果＞
　次に、本実施の形態における照明制御装置１０、照明演出システム１及び照明制御方法の作用効果について説明する。 <Effect>
Next, 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.
　例えば、従来技術では、１つの照射対象物に対して１つの照明シーンを実行するものである。この場合、隣り合う２つの照射対象物に対して１つの照明シーンを実行する場合、隣り合う２つの照射対象物の大きさ及び形状が互いに異なるため、実行された照明シーンの大きさに差異が生じた状態で見えることがある。このため、隣り合う２つの照射対象物に対して実演された照明シーンにズレが生じ、適切な照明シーンを実現し難い場合がある。 For example, in the conventional technology, one lighting scene is executed for one illumination target. In this case, when one illumination scene is executed for two adjacent irradiation targets, the sizes and shapes of the two adjacent irradiation targets are different from each other. It can be seen as it arises. For this reason, the lighting scenes demonstrated for two adjacent irradiation objects are deviated, and it may be difficult to realize an appropriate lighting scene.
　しかしながら、本実施の形態の照明制御装置１０は、複数の照明に関する情報と、画像コンテンツとを記憶する記憶部１３と、処理部１１とを備える。照明に関する情報は、照明器具３０の光が照射される照射対象物を含んだ背景画像と、背景画像が示す空間情報と、背景画像上に配置されている複数の仮想の照明器具３０ａのそれぞれの位置情報とを含む。また、処理部１１は、複数の照明に関する情報のうちの２以上の照明に関する情報を１つに合成し、１つに合成した合成情報（例えば、１つの照明演出領域）を生成する。そして、処理部１１は、合成情報及び画像コンテンツに基づいて、合成情報に含まれる複数の仮想の照明器具３０ａに対応する複数の照明器具３０で２以上の照射対象物を照射する光の演出として再現可能な複数の照明シーンを１つの照明シーンとして生成する。 However, the lighting control device 10 of the present embodiment includes a storage unit 13 that stores information on a plurality of lights and image content, and a processing unit 11 . The lighting information includes a background image including an illumination target illuminated by the light of the lighting device 30, spatial information indicated by the background image, and information on each of the plurality of virtual lighting devices 30a arranged on the background image. location information; In addition, the processing unit 11 synthesizes two or more pieces of illumination-related information among a plurality of pieces of illumination-related information into one, and generates combined information (for example, one lighting effect area). Then, based on the synthesis information and the image content, the processing unit 11 irradiates the two or more illumination targets with the plurality of lighting fixtures 30 corresponding to the plurality of virtual lighting fixtures 30a included in the synthesis information. To generate a plurality of reproducible lighting scenes as one lighting scene.
　これによれば、複数の照射対象物に対して照明シーンを実行する場合、２以上の照明に関する情報を合成することで、照明に関する情報を１つに纏めることができる。このため、複数の照射対象物を１つに合成した照明演出領域と画像コンテンツとを用いて、１つの照明シーンを再現することができるため、複数の照射対象物における位置、大きさ及び形状に差異があっても、複数の照射対象物に実演された照明シーンにズレが生じ難い。 According to this, when a lighting scene is executed for a plurality of irradiation targets, information regarding lighting can be combined into one by synthesizing information regarding two or more lightings. For this reason, it is possible to reproduce a single lighting scene by using the lighting effect area and the image content obtained by synthesizing a plurality of irradiation targets. Even if there is a difference, it is difficult for the lighting scenes demonstrated on a plurality of irradiation objects to be displaced.
　したがって、照明制御装置１０では、複数の照射対象物に対して１つの照明シーンによる演出を行うことができる。その結果、ユーザは、複数の照射対象物において一体的な照明シーンが実演されることで、違和感を生じ難い。 Therefore, with the lighting control device 10, a single lighting scene can be produced for a plurality of irradiation targets. As a result, the user is less likely to feel a sense of incongruity due to the performance of an integrated lighting scene on a plurality of irradiation targets.
　また、本実施の形態の照明演出システム１において、照明制御装置１０と、複数の照射対象物のそれぞれに設置され、複数の照射対象物に光を照射する複数の照明器具３０とを備える。 In addition, the lighting production system 1 of the present embodiment includes the lighting control device 10 and a plurality of lighting fixtures 30 that are installed in each of the plurality of irradiation objects and irradiate the plurality of irradiation objects with light.
　この照明制御方法においても、上述と同様の作用効果を奏する。 This lighting control method also has the same effects as described above.
　また、本実施の形態の照明制御方法において、複数の照明に関する情報と、画像コンテンツとを記憶し、照明に関する情報は、照明器具３０の光が照射される照射対象物を含んだ背景画像と、背景画像が示す空間情報と、背景画像上に配置されている複数の仮想の照明器具３０ａのそれぞれの位置情報とを含み、複数の照明に関する情報のうちの２以上の照明に関する情報を１つに合成し、１つに合成した合成情報を生成し、合成情報及び画像コンテンツに基づいて、合成情報に含まれる複数の仮想の照明器具３０ａに対応する複数の照明器具３０で２以上の照射対象物を照射する光の演出として再現可能な複数の照明シーンを１つの照明シーンとして生成する。 Further, in the lighting control method of the present embodiment, a plurality of pieces of information about lighting and image content are stored, and the information about lighting includes a background image including an irradiation target to which the light of the lighting device 30 is irradiated, The spatial information indicated by the background image and the position information of each of the plurality of virtual lighting fixtures 30a arranged on the background image are included, and the information regarding two or more of the plurality of information regarding lighting is integrated into one. Synthesizing and synthesizing into one to generate synthesizing information, and based on the synthesizing information and the image content, two or more irradiation targets are illuminated by a plurality of lighting fixtures 30 corresponding to the plurality of virtual lighting fixtures 30a included in the synthesizing information. To generate a plurality of lighting scenes reproducible as one lighting scene as a performance of light for irradiating.
　この照明制御方法においても、上述と同様の作用効果を奏する。 This lighting control method also has the same effects as described above.
　また、本実施の形態の照明制御装置１０において、処理部１１は、複数の照明に関する情報における空間情報に基づいて、複数の照射対象物に対して照射する光の演出である照明シーンの大きさを統一する。そして、処理部１１は、複数の照明に関する情報を１つに合成して合成情報を生成する。 In addition, in the lighting control device 10 of the present embodiment, the processing unit 11 determines the size of the lighting scene, which is the performance of the light irradiated to the plurality of irradiation targets, based on the spatial information in the information about the plurality of lighting. unify. Then, the processing unit 11 synthesizes a plurality of pieces of information about illumination into one to generate synthesized information.
　これによれば、複数の照射対象物に対して照射する光の演出である照明シーンの大きさを統一することができる。つまり、照明シーンの大きさを大きくしたり、小さくしたりすることで、全ての照射対象物に対して実演される照明シーンの大きさを同一にすることができる。このため、ユーザに対して違和感を生じさせないように１つの照明シーンによる演出を行うことができる。 According to this, it is possible to unify the size of the lighting scene, which is the effect of the light irradiated on the plurality of irradiation targets. In other words, by increasing or decreasing the size of the illumination scene, the size of the illumination scene demonstrated for all the irradiation objects can be made the same. Therefore, it is possible to perform an effect using one lighting scene so as not to make the user feel uncomfortable.
　また、本実施の形態の照明制御装置１０において、処理部１１は、複数の照明に関する情報のうちの１つの照明に関する情報における空間情報を基準として、複数の照射対象物に対して照射する光の演出である照明シーンの大きさを統一する。そして、処理部１１は、複数の照明に関する情報を１つに合成して合成情報を生成する。 In addition, in the lighting control device 10 of the present embodiment, the processing unit 11 determines the light to be irradiated to the plurality of irradiation targets based on the spatial information in the information regarding one lighting among the information regarding the plurality of lighting. Unify the size of the lighting scene that is the production. Then, the processing unit 11 synthesizes a plurality of pieces of information about illumination into one to generate synthesized information.
　これによれば、基準となる１つの照明に関する情報における空間情報を設定することで、他の照射対象物に対して実演する照明シーンの大きさを統一することができる。つまり、照明シーンの大きさを大きくしたり、小さくしたりすることで、全ての照射対象物に対して実演される照明シーンの大きさを同一にすることができる。このため、ユーザに対して違和感を生じさせないように１つの照明シーンによる演出を行うことができる。 According to this, it is possible to unify the size of the lighting scene to be demonstrated for other irradiation objects by setting the spatial information in the information about one lighting that serves as a reference. In other words, by increasing or decreasing the size of the illumination scene, the size of the illumination scene demonstrated for all the irradiation objects can be made the same. Therefore, it is possible to perform an effect using one lighting scene so as not to make the user feel uncomfortable.
