[0010] Note that all of the embodiments described below show comprehensive or specific examples. The numerical values, shapes, materials, components, arrangement positions and connection forms of the components, steps, order of steps, etc. shown in the following embodiments are merely examples and are not intended to limit the present disclosure. In addition, among the components in the following embodiments, the components not described in the independent claims are described as optional components.

[0011] In addition, each figure is a schematic diagram and is not necessarily drawn precisely. Also, in each figure, the same reference numerals are given to the same components.

[0012] Hereinafter, the embodiments will be specifically described with reference to the drawings.

[0013] (Embodiment) <Configuration: Presentation System 1> FIG. 1A is a block diagram showing a presentation system 1 according to the embodiment.

[0014] As shown in FIG. 1A, in the presentation system 1, it is possible to light up an illumination target such as a building existing in the first lighting installation space with symbol colors and awareness colors, or to propose a light color mode for lighting the inside of the first lighting installation space in a desired manner. For example, in the presentation system 1, by controlling the lighting device 3a installed in the first lighting installation space, a plan of light color (light color mode) as an illumination mode is presented.

[0015] Here, the first lighting installation space is a space in which the lighting device 3a is installed, and is a space including an illumination target to be lit up by the lighting device 3a.

[0016] In addition, the light color mode is a mode of lighting up with a single color or a plurality of colors, lighting the inside of the first lighting installation space with a single color or a plurality of colors, or changing the light color and brightness according to the passage of time.

[0017] The presentation system 1 includes a first information processing device 10, a lighting system 3, a storage unit 30, and a second information processing device 20.

[0018] The first information processing device 10 can propose a light color mode for lighting the inside of the first lighting installation space in a desired manner. The first information processing device 10 has a first acquisition unit 11a, a first calculation unit 11b, and a first output unit 11c.

[0019] The first acquisition unit 11a acquires first information, which is information indicating an image of the light color mode to be realized in the first lighting installation space. The first acquisition unit 11a acquires the first information via, for example, the Internet, a local network, a storage device, or the like. The first acquisition unit 11a outputs the acquired first information to the first calculation unit 11b. In addition, the first acquisition unit 11a may acquire a plurality of pieces of first information used when calculating the first image light color. The first acquisition unit 11a is an example of an acquisition unit.

[0020] Here, the first information includes first image information indicating an image of an image that the user wants to achieve in the first lighting installation space, and information regarding the first lighting installation space. The first image information is information indicating an image in which the image that the user wants to achieve in the first lighting installation space is captured, and may be a still image or a moving image. The information regarding the first lighting installation space is information including information regarding the light color corresponding to the image that the user wants to achieve in the first lighting installation space, material information of the illumination target in the first lighting installation space, and the like. The information regarding the light color corresponding to the image is, for example, a chromaticity value measured by a measuring instrument or the like. The material information is the color, reflectance, shape, and the like of the illumination target. In the present embodiment, when the illumination target is irradiated with light, the desired light color pattern may not be achieved depending on the color, reflectance, shape, and the like of the illumination target, and thus the material information is taken into consideration.

[0021] The first calculation unit 11b calculates a first image light color, which is a likely light color estimated from the first information (calculates a color estimation value). Specifically, the first calculation unit 11b calculates an image color, which is a representative color (representative color) of the first image information, based on the first image information, and calculates a first image light color, which is a light color estimated from the calculated image color. In the calculation of the first image light color, machine learning, statistical processing, and mathematical processing are selectively executed. Further, the first calculation unit 11b can also calculate an image color, which is a representative color of the information regarding the light color, based on the information regarding the light color, and calculate a first image light color, which is a light color estimated from the calculated image color. The calculated first image light color is information for the lighting device 3a to achieve by lighting. The first calculation unit 11b is an example of a calculation unit.

[0022] Further, the first calculation unit 11b can also extract predetermined first information from a plurality of first information, and calculate a first image light color, which is a likely light color estimated from the extracted predetermined first information.

[0023] Here, the plausible light color is a light color (first image light color) derived from the image color, which is the representative color of the first image information. The representative color is the upper-ranked color among the colors constituting the image shown in the first image information ranked according to a predetermined criterion. The upper-ranked color is, for example, a color ranked above a predetermined rank among the colors ranked according to a predetermined criterion such as the dominant color, the most vivid color, the brightest color, the warmest color, etc. in the image. Also, the predetermined rank is a rank determined in advance.

[0024] Here, the image color is the representative color of the first image information and is the color that the user wants to achieve in the first lighting installation space, that is, the color desired by the user. The image color may be a single color or a plurality of colors.

[0025] Here, the image light color is a light color estimated from the image color and is the light color that the user wants to achieve in the first lighting installation space, that is, the light color desired by the user. The image light color is expressed on a CIE chromaticity diagram or the like. The image light color may be one light color or a plurality of light colors.

[0026] FIG. 1B is a diagram schematically showing a comparison between the measured value of the first image light color and the first color based on the plan of the first image light color.

[0027] Further, as shown in FIG. 1B, the first arithmetic unit 11b calculates (calculates a color estimation value) the first color, which is a representative color of the second image information, based on the second image information indicating the light color mode when the plan of the first image light color is realized in the first lighting installation space. That is, the first arithmetic unit 11b acquires the imaged second image information from the first acquisition unit 11a when the first image light color actually realized in the first lighting installation space is imaged and formed into an image, and calculates the first color, which is a representative color, based on the acquired second image information. Further, since the first image light color can be expressed on a CIE chromaticity diagram or the like, the first arithmetic unit 11b compares the actually measured value of the first image light color with the first color. The actually measured value of the first image light color includes a chromaticity value measured by a measuring instrument or the like, a DMX (Digital Multiplex) value, an assumed chromaticity, lighting device information (colors that the lighting device 3a can represent), a chromaticity obtained by visually judging the first image light color actually realized in the first lighting installation space, and the like. The first arithmetic unit 11b calculates the difference between the calculated first color and the actually measured value of the first image light color by comparing the first color with the actually measured value of the first image light color. The first arithmetic unit 11b stores the calculated difference in the storage unit 30 via the first output unit 11c.

[0028] The difference is stored in the storage unit 30 as a database 30a. The storage unit 30 learns the difference between the first color and the actually measured value of the first image light color by databaseizing and accumulating the difference calculated by the first arithmetic unit 11b.

[0029] For example, by learning the difference with the actually measured value of the first image light color as teacher data, the first arithmetic unit 11b can calculate the first image light color according to the learned database 30a. That is, when calculating the first image light color, the first arithmetic unit 11b can calculate the first image light color, which is a likely light color estimated from at least the first information, by recursively using the difference. The first arithmetic unit 11b outputs the calculated first image light color to the first output unit 11c.

[0030] Also, when calculating the first image light color, the first calculation unit 11b outputs a light color plan clustered based on the material information of the first information to the first output unit 11c. That is, the first calculation unit 11b groups the light color plans according to the type of material information and outputs the grouped light color plans.

[0031] The first output unit 11c obtains the first image light color from the first calculation unit 11b and outputs the obtained first image light color, thereby presenting it as a light color plan. For example, the first output unit 11c outputs the first image light color to the lighting system 3 for controlling the lighting device 3a, so that a light color plan corresponding to the first image light color is realized in the first lighting installation space. Also, when the first output unit 11c is a display unit, the first image light color can be displayed using a virtual image. The first output unit 11c is an example of an output unit.

[0032] The lighting system 3 can control the light color mode of the lighting device 3a by obtaining the first image light color from the first output unit 11c of the first information processing device 10.

[0033] The lighting system 3 includes a lighting control device 3b and a lighting device 3a.

[0034] The lighting control device 3b controls the light color mode of the lighting device 3a. The lighting control device 3b obtains the first image light color from the first output unit 11c of the first information processing device 10, and controls the light color mode of the lighting device 3a, such as light color, lighting on / off, lighting (irradiation) direction, or brightness, based on the control information corresponding to the obtained first image light color.

[0035] The lighting device 3a is installed in the first lighting installation space, lights up the lighting object, or illuminates the inside of the first lighting installation space with a desired light color mode. The lighting device 3a is a projector such as a spotlight, but is not limited to a projector such as a spotlight, and any known lighting device may be used.

[0036] As a result, since the plan of the first image light color generated based on the first image information is realized in the first lighting installation space, the user can visually recognize the realized first image light color.

[0037] The second information processing device 20 can propose a light color pattern for illuminating the inside of a second lighting installation space, which is a lighting installation space different from the first lighting installation space, in a desired manner. The second information processing device 20 is an external device different from the first information processing device 10 and has the same functions as the first information processing device 10. Since the second information processing device 20 has the same configuration as the first information processing device 10, the description thereof will be omitted as appropriate. Note that the second information processing device 20 is not an essential component in the presentation system 1.

[0038] The second information processing device 20 includes a second acquisition unit 21a, a second calculation unit 21b, and a second output unit 21c.

[0039] The second acquisition unit 21a acquires second information, which is information indicating an image of a light color pattern to be realized in the second lighting installation space. The second acquisition unit 21a outputs the acquired second information to the second calculation unit 21b.

[0040] Here, the second information includes third image information, which is information obtained by imaging the light color pattern realized in the second lighting installation space, and information related to the second lighting installation space. The third image information is imaged information indicating the light color pattern realized by another user in the second lighting installation space and is a still image, but may also be a moving image. The information related to the second lighting installation space is information including information related to the light color realized by another user in the second lighting installation space, material information of the lighting target in the second lighting installation space, and the like.

[0041] The second calculation unit 21b calculates a second color, which is a representative color of the third image information, based on the third image information (calculates a color estimation value). The second calculation unit 21b is an example of a calculation unit. The representative color is the top-ranked color among the colors constituting the image shown in the third image information ranked according to a predetermined standard.

[0042] Here, the second color is a representative color of the third image information and is a color realized by another user in the second lighting installation space.

[0043] Also, the second arithmetic unit 21b compares the measured value of the light color mode realized in the second lighting installation space with the second color. The measured value of the light color mode realized in the second lighting installation space includes the chromaticity value measured by a measuring instrument or the like, the DMX (Digital Multiplex) value, the assumed chromaticity, the lighting device information (the color that the lighting device 3a can represent), and the chromaticity determined visually for the light color actually realized in the second lighting installation space. By performing the comparison, the second arithmetic unit 21b calculates the difference between the second color and the measured value of the light color mode realized in the second lighting installation space, and stores the calculated difference in the storage unit 30. Note that the comparison between the measured value of the light color mode realized in the second lighting installation space and the second color is the same as that in FIG. 1B, so the illustration is omitted.

[0044] The storage unit 30 also learns the difference between the second color and the measured value of the light color mode realized in the second lighting installation space by databaseizing and accumulating the difference calculated by the second arithmetic unit 21b of the second information processing apparatus 20.

[0045] That is, not only for the first information processing apparatus 10 but also for the second information processing apparatus 20, by using the measured value of the light color mode realized in the second lighting installation space as teacher data to learn the difference, the second arithmetic unit 21b can calculate the light color to be realized in the second lighting installation space according to the learned database 30a. That is, when calculating the light color to be realized in the second lighting installation space, the second arithmetic unit 21b can calculate at least a plausible light color (the light color to be realized in the second lighting installation space) estimated from the second information by recursively using the difference. The second arithmetic unit 21b outputs the calculated light color to be realized in the second lighting installation space to the second output unit 21c.

[0046] The second output unit 21c acquires the light color to be realized in the second lighting installation space from the second calculation unit 21b, and outputs the acquired light color. For example, the second output unit 21c outputs to another lighting system for controlling another lighting device installed in the second lighting installation space, so that the light color is realized within the second lighting installation space.

[0047] <Processing operation> Next, the processing operations of the light color plan presentation method and the presentation system 1 according to the present embodiment will be described.

[0048] FIG. 2 is a flowchart showing the processing operation when the first information processing device 10 of the presentation system 1 according to the embodiment proposes the first image light color.

[0049] First, as shown in FIG. 2, the first acquisition unit 11a of the first information processing device 10 acquires first information which is information indicating an image of a light color mode to be realized in the first lighting installation space (S11: step of acquiring first information). The first acquisition unit 11a outputs the acquired first information to the first calculation unit 11b.

[0050] Next, the first calculation unit 11b acquires the first information from the first acquisition unit 11a, and calculates a first image light color which is a likely light color estimated from the first information based on the acquired first information.

[0051] If the first information is first image information, the first calculation unit 11b calculates an image color which is a representative color of the first image information based on the first image information. Also, if the first information is information regarding a light color, the first calculation unit 11b calculates an image color which is a representative color of the information regarding the light color (calculates a color estimation value) based on the information regarding the light color (S12: step of calculating an image color). Note that the first calculation unit 11b may calculate the image color using the database 30a regarding the above-mentioned difference if the database 30a exists in the storage unit 30.

[0052] Next, the first arithmetic unit 11b calculates a first image light color, which is a light color estimated from the calculated image color (S13: step of calculating the first image light color).

[0053] Next, the first arithmetic unit 11b outputs the calculated first image light color to the first output unit 11c. That is, the first information processing apparatus 10 outputs the first image light color to the lighting system 3 (S14: step of outputting the first image light color). Then, the first information processing apparatus 10 ends the processing operation shown in FIG. 2.

[0054] The lighting system 3 realizes a plan of a light color corresponding to the first image light color within the first lighting installation space. That is, the lighting control device 3b of the lighting system 3 acquires the first image light color from the first information processing apparatus 10, and controls the light color mode of the lighting device 3a, such as the light color, lighting on / off, lighting (irradiation) direction, or brightness, based on the control information corresponding to the acquired first image light color. Thereby, the lighting device 3a actually lights up the lighting object or actually lights the first lighting installation space in a desired mode. In this way, the presentation system 1 can propose a plan of the first image light color based on the first information.

[0055] Also, the user checks the actual light color mode in the first lighting installation space, and if it is a desired light color mode, the user adopts the first image light color. However, the first image light color may be different from the desired light color mode of the user.

[0056] Therefore, in order to satisfy the user's request, the presentation system 1 executes the following processing operations as shown in FIG. 3.

[0057] FIG. 3 is a flowchart showing a processing operation in which the first information processing apparatus 10 of the presentation system 1 according to the embodiment learns the difference.

[0058] First, the first arithmetic unit 11b acquires, via the first acquisition unit 11a, second image information that has been imaged by imaging the first image light color actually realized in the first lighting installation space (S21). For example, the user images the light color pattern of the first image light color actually realized in the first lighting installation space using an imaging device or the like, and inputs the second image information imaged by the user to the first information processing device 10, whereby the first arithmetic unit 11b acquires the second image information via the first acquisition unit 11a.

[0059] Also, the first arithmetic unit 11b acquires, via the first acquisition unit 11a, the measured value when calculating the first image light color (S21).

[0060] Next, the first arithmetic unit 11b calculates (calculates a color estimation value) a first color, which is a representative color of the second image information, based on the second image information (S22: step of calculating the first color).

[0061] Next, the first arithmetic unit 11b calculates the difference between the calculated first color and the measured value of the first image light color by comparing the first color and the measured value of the first image light color (S23: step of calculating the difference).

[0062] Next, the first arithmetic unit 11b stores the calculated difference in the storage unit 30 (S24: step of storing). Then, the first information processing device 10 ends the processing operation in FIG. 3.

[0063] As a result, the storage unit 30 accumulates the differences calculated by the first arithmetic unit 11b in a database, and by learning the difference between the first color and the measured value of the first image light color, the presentation system 1 can propose a more accurate plan for the first image light color.

[0064] Also, when using the database 30a of the differences learned by the first arithmetic unit 11b, the presentation system 1 executes the following processing operation as shown in FIG. 4.

[0065] FIG. 4 is a flowchart showing the processing operation when the first information processing apparatus 10 of the presentation system 1 according to the embodiment proposes a first image light color based on a difference.

[0066] First, the first acquisition unit 11a acquires first information (S11), and outputs the acquired first information to the first calculation unit 11b.

[0067] Next, the first calculation unit 11b acquires the first information from the first acquisition unit 11a, and calculates a first image light color, which is a likely light color estimated from the acquired first information, based on the first information.

[0068] If the first information is first image information, the first calculation unit 11b calculates an image color, which is a representative color of the first image information, by recursively using the difference based on the first image information and the database 30a of the storage unit 30. Also, if the first information is information related to a light color, the first calculation unit 11b calculates an image color, which is a representative color of the information related to the light color, by recursively using the difference based on the information related to the light color and the database 30a of the storage unit 30 (calculate a color estimation value) (S32: step of calculating an image light).

[0069] Next, the first calculation unit 11b calculates a first image light color, which is a light color estimated from the calculated image color and recursively uses the difference (S33: step of calculating the first image light color).

[0070] Next, the first calculation unit 11b outputs the first image light color, which recursively uses the difference, to the first output unit 11c. Thereby, the first information processing apparatus 10 outputs the first image light color, which recursively uses the difference, to the lighting system 3 (S34: step of outputting the first image light color). Then, the first information processing apparatus 10 ends the processing operation of FIG. 4.

[0071] The lighting system 3 realizes a light color plan according to the first image light color that recursively utilizes differences within the first lighting installation space. Specifically, the lighting device 3a actually lights up the object to be illuminated or actually illuminates the first lighting installation space in a desired manner. As a result, the presentation system 1 can propose a plan for the first image light color that recursively utilizes differences based on the first information and the database 30a of the storage unit 30.

[0072] Next, the processing operation in the second information processing device 20 will be described with reference to FIG. 5.

[0073] FIG. 5 is a flowchart showing the processing operation in which the second information processing device 20 of the presentation system 1 according to the embodiment learns differences.

[0074] First, as shown in FIG. 5, the second arithmetic unit 21b of the second information processing device 20 acquires, via the second acquisition unit 21a, third image information which is information obtained by imaging the light color pattern actually realized in the second lighting installation space (S41: step of acquiring second information). For example, by another user imaging the light color pattern actually realized in the second lighting installation space with an imaging device or the like and inputting the third image information imaged by another user to the second information processing device 20, the second arithmetic unit 21b acquires the third image information via the second acquisition unit 21a.

[0075] Also, the second arithmetic unit 21b also acquires the measured value when calculating the light color pattern realized in the second lighting installation space via the second acquisition unit 21a (S41).

[0076] Next, the second arithmetic unit 21b calculates (calculates the color estimation value) the second color which is a representative color of the third image information based on the third image information (S42: step of calculating the second color).

[0077] Next, the second arithmetic unit 21b calculates the difference between the second color and the measured value of the light color pattern realized in the second lighting installation space by comparing the second color with the measured value of the light color pattern realized in the second lighting installation space (S43: step of calculating the difference).

[0078] Next, the second arithmetic unit 21b stores the calculated difference in the storage unit 30 (S44: storage step). Then, the second information processing apparatus 20 ends the processing operation in FIG. 5.

[0079] As a result, the storage unit 30 creates a database of the differences calculated by the second arithmetic unit 21b and accumulates them, and learns the differences between the second color and the measured values of the light color patterns realized in the second lighting installation space. In the presentation system 1, more accurate color estimation can be performed, and a more accurate first image light color plan can be proposed in the first information processing apparatus 10.

[0080] Also, when using the database 30a of the differences learned by the second arithmetic unit 21b, the presentation system 1 executes the following processing operation as shown in FIG. 6.

[0081] FIG. 6 is a flowchart showing another processing operation in which the second information processing apparatus 20 of the presentation system 1 according to the embodiment learns differences.

[0082] First, the first arithmetic unit 11b acquires, via the second acquisition unit 21a, the third image information and the measured value when calculating the light color pattern realized in the second lighting installation space (S41).

[0083] Next, based on the third image information and the database 30a of the storage unit 30, the second arithmetic unit 21b recursively uses the differences to calculate the second color, which is the representative color of the third image information and for which the differences are recursively used (S52: step of calculating the second color).

[0084] Next, the second arithmetic unit 21b compares the second color for which the differences are recursively used with the measured value of the light color pattern realized in the second lighting installation space, thereby calculating the difference between the second color for which the differences are recursively used and the measured value of the light color pattern realized in the second lighting installation space (S53: step of calculating the difference).

[0085] Next, the second arithmetic unit 21b causes the storage unit 30 to store the calculated difference (S54: storage step). Then, the second information processing apparatus 20 ends the processing operation in FIG. 6.

[0086] As a result, the difference calculated by the second arithmetic unit 21b is accumulated in the storage unit 30 in the form of a database, and by further learning the difference between the second color and the measured value of the light color mode realized in the second lighting installation space, the presentation system 1 can perform more accurate color estimation and can propose a more accurate first image light color plan in the first information processing apparatus 10.

[0087] <Function and effect> Next, the function and effect of the light color plan presentation method and the presentation system 1 in the present embodiment will be described.

[0088] As described above, the light color plan presentation method of the present embodiment is a light color plan presentation method for presenting a light color plan by controlling the lighting device 3a installed in the first lighting installation space, including a step of acquiring first information which is information indicating an image of a light color mode desired to be realized in the first lighting installation space, a step of calculating a first image light color which is a likely light color estimated from the first information, and a step of outputting the calculated first image light color.

[0089] According to this, based on the first information, it is possible to calculate a first image light color which is a likely light color estimated from the first information.

[0090] Also, if the first information is the information desired by the user, it is possible to propose a plan for illuminating the first lighting installation space in the light color mode desired by the user. That is, unlike the conventional light color plan presentation method, it is possible to simply propose the light color mode desired by the user without requiring a long time for setting by repeating the adjustment of individual light colors at the site while the lighting setter grasps the intention of the user.

[0091] In addition, since the first image light color is calculated based on the first information, it is difficult for variations to occur in the plan proposal for the first image light color as in the prior art.

[0092] Therefore, according to the light color plan presentation method, it is possible to suppress variations in the setting of the light color mode and also suppress the prolongation of the setting time. Further, since it is possible to suppress the prolongation of the usage time of the presentation system 1 required for the setting by the lighting setter or the like, it is also possible to suppress the increase in the energy cost in the presentation system 1.

[0093] Further, the presentation system 1 of the present embodiment is a presentation system 1 that presents a light color plan by controlling the lighting device 3a installed in the first lighting installation space, and includes an acquisition unit that acquires first information which is information indicating an image of a light color mode to be realized in the first lighting installation space, a calculation unit that calculates a first image light color which is a likely light color estimated from the first information acquired by the acquisition unit, and an output unit that outputs the first image light color calculated by the calculation unit.

[0094] Also in this presentation system 1, the same operational effects as described above are achieved.

[0095] Further, in the light color plan presentation method of the present embodiment, the first information includes first image information which is information indicating an image to be realized in the first lighting installation space. And in the step of calculating the first image light color, it includes calculating an image color which is a representative color of the first image information based on the first image information, and calculating a first image light color which is a light color estimated from the image color.

[0096] According to this, by using the first image information desired by the user, it is possible to calculate a first image light color corresponding to the first image information. For this reason, it becomes possible to propose a plan for illuminating the first lighting installation space with a light color mode close to the light color mode desired by the user.

[0097] In addition, in the light color plan presentation method of the present embodiment, the first information includes information regarding the first lighting installation space. Further, the information regarding the first lighting installation space includes information regarding the light color according to the image desired to be realized in the first lighting installation space. And in the step of calculating the first image light color, it includes calculating an image color, which is a representative color of the information regarding the light color, based on the information regarding the light color, and calculating the first image light color, which is the light color estimated from the image color.

[0098] According to this, by using the information regarding the first lighting installation space desired by the user, the first image light color corresponding to the information regarding the first lighting installation space can be calculated. Therefore, it becomes possible to propose a plan for illuminating the first lighting installation space with a light color mode close to the light color mode desired by the user.

[0099] In addition, the light color plan presentation method of the present embodiment includes a step of calculating a first color, which is a representative color of second image information, based on the second image information indicating the light color mode when the plan of the first image light color is realized in the first lighting installation space, and a step of calculating the difference between the calculated first color and the measured value of the first image light color.

[0100] According to this, as shown in FIG. 7, the first image light color is represented by the range indicated by the dashed triangle, but there may be a deviation between the color estimation value (indicated by a cross) when the plan of the first image light color with respect to the initial value (indicated by a square) is realized in the first lighting installation space and the measured value (indicated by a black circle) of the first image light color with respect to the initial value (indicated by a square). Therefore, by calculating the difference between the first color and the measured value of the first image light color, when presenting the plan of the first image light color to the user, a plan of the first image light color closer to the user's desire can be presented.

[0101] In addition, the light color plan presentation method of the present embodiment includes a step of acquiring second information, which is information indicating an image of the light color mode desired to be realized in a second lighting installation space, which is a lighting installation space different from the first lighting installation space.

[0102] According to this, by using the second information in the second lighting installation space other than the first lighting installation space, more differences can be calculated. Therefore, a plan of a light color mode closer to the user's desire can be presented.

[0103] Further, in the light color plan presentation method of the present embodiment, the second information includes third image information which is information obtained by imaging the light color mode realized in the second lighting installation space, and information regarding the second lighting installation space. The light color plan presentation method further includes a step of calculating a second color which is a representative color of the third image information based on the third image information, and a step of calculating a difference between the second color and the measured value of the light color mode realized in the second lighting installation space.

[0104] According to this, by calculating the difference between the second color and the measured value of the light color mode realized in the second lighting installation space, when presenting a plan of the light color mode to the user, a plan of a light color mode closer to the user's desire can be presented. Therefore, the light color mode can be set with less variation and the extension of the setting time can be suppressed.

[0105] Further, the light color plan presentation method of the present embodiment includes a step of storing the difference in the storage unit 30.

[0106] According to this, by storing and learning the difference, a plan of the first image light color closer to the user's desire can be proposed. As a result, the extension of the usage time of the presentation system 1 required for setting by a lighting setter or the like can be suppressed, and thus the increase in the energy cost in the presentation system 1 can also be suppressed.

[0107] Further, in the light color plan presentation method of the present embodiment, in the step of calculating the first image light color, the difference is acquired from the storage unit 30 and the difference is used recursively, thereby calculating the first image light color which is a likely light color estimated from at least the first information.

[0108] According to this, by learning the difference, the difference can be used recursively. Therefore, based on the learned database 30a, it becomes possible to propose a plan for the first image light color that the user desires more. As a result, it is possible to suppress the lengthening of the usage time of the presentation system 1 required for the setting by the lighting setter or the like, and thus it is also possible to suppress the increase in the energy cost in the presentation system 1.

[0109] Also, in the light color plan presentation method of the present embodiment, the information regarding the first lighting installation space includes the material information of the first lighting installation space. And in the step of calculating the first image light color, a light color plan clustered based on the material information is output.

[0110] According to this, it becomes possible to cluster according to the classification preset according to the material information of the first lighting installation space. Therefore, by classifying according to the type of material information, it becomes possible to calculate the first image light color desired by the user according to the classification.

[0111] Also, in the light color plan presentation method of the present embodiment, in the step of calculating the first image light color, a plurality of first information to be used is acquired.

[0112] According to this, by acquiring a plurality of first information, it becomes possible to more accurately realize the light color mode desired by the user.

[0113] Also, in the light color plan presentation method of the present embodiment, predetermined first information is extracted from the plurality of first information, and the first image light color, which is a likely light color estimated from the extracted predetermined first information, is calculated.

[0114] According to this, for example, a plurality of first information can be acquired via the Internet, and the first information preferable to the user's preference can be extracted from the acquired plurality of first information. Therefore, it becomes possible to more accurately realize the light color mode desired by the user from the plurality of first information.
