[Outline of lighting system]
An outline of a lighting system according to an embodiment will be described.

FIG. 1 is a block diagram showing the functional configuration of the lighting system according to the embodiment.

The lighting system 100 is a production lighting system that can cause the lighting fixtures 10 to emit light in the same color as specific pixels included in moving image content. Although the color of specific pixels included in the moving image content changes over time, the lighting system 100 generates lighting control data for controlling the lighting device 10 based on the change over time of the color at this time, This can be reflected in the color of light emitted from the lighting device 10 . For example, if the moving image content is content in which clouds move against a blue sky, a change in color of specific pixels in the moving image content according to the movement of the clouds is reflected in the light emission color of the lighting device 10 .

A plurality of lighting fixtures 10 are installed, for example, on the outer wall of a building such as a building, and each of the plurality of lighting fixtures 10 is associated with pixel information included in moving image content.

FIG. 2 is a diagram showing an example of correspondence relationships between a plurality of lighting fixtures 10 and pixels of moving image content.

The specified range R1 of the moving image content shown in (a) of FIG. 2 is associated with the specific region R2 of the outer wall of the building 80 shown in (b) of FIG. As a result, the lighting fixtures L1 to L4 are associated with the pixels P1 to P4 of the video content and emit light in the same colors as the pixels P1 to P4.

The processing terminal 50 controls the plurality of lighting fixtures 10 by providing lighting control data d to each of the plurality of lighting fixtures 10 through the wide area communication network 70 . The lighting control data d is data for controlling light emission of the lighting device 10 . The processing terminal 50 generates lighting control data d corresponding to each of the plurality of lighting fixtures 10 .

The processing terminal 50 is implemented as a terminal device such as a personal computer, for example. Note that the processing terminal 50 may be implemented as a server device (cloud server). The processing terminal 50 is arranged in a space separate from the space (outside the building 80) in which the lighting fixture 10 is installed, such as inside the building 80, for example.

In FIG. 3 , the rendering area A in which lighting effects are performed using a plurality of lighting fixtures 10 is indicated by the area within the outer frame, and the arrangement positions of the multiple lighting fixtures 10 in the rendering area A are indicated by hatched circles. is indicated. The display unit 57 may display an image of the moving image content described above.

The storage unit 52 is a storage device that stores information (computer programs, etc.) necessary for the processing terminal 50 to perform data processing and the like. The storage unit 52 is implemented by, for example, an HDD (Hard Disk Drive), but may be implemented by a semiconductor memory.

For example, the storage unit 52 stores moving image content to be referred to for lighting effects using a plurality of lighting fixtures 10 . The moving image content is not limited to images of clouds, and may be images of fireworks, fountains, rainbows, aurora, or the like. Note that moving image content is not limited to moving image format content, and includes still image format content. This embodiment can also be applied to content in the form of still images.

In addition, the storage unit 52 stores arrangement information of a plurality of lighting fixtures 10 . The arrangement information includes positional coordinates of the lighting fixtures 10 in the rendering area A, for example, information about the horizontal distance and height of the lighting fixtures 10 with respect to a predetermined point. The arrangement information may include information about the size of the light exit surface of the lighting device 10 or the light exit direction. Further, the layout information of the lighting fixture 10 may include layout information of objects around the lighting fixture 10, for example, layout information of the building 80 in which the lighting fixture 10 is installed.

The data processing unit 54 generates lighting control data d for dimming control and toning control of the plurality of lighting fixtures 10 . The data processing unit 54 is implemented by, for example, a microcomputer, but may be implemented by a processor.

In the present embodiment, the data processing unit 54 selects one or more lighting fixtures 10 out of the plurality of lighting fixtures 10 based on the arrangement information of the plurality of lighting fixtures 10 before generating the lighting control data d. (see FIG. 4). The generated lighting fixture group G is displayed on the display section 57 .

FIG. 4 is a diagram showing an example of the rendering area A and the divided area B displayed on the processing terminal 50. As shown in FIG.

As shown in FIG. 4, the data processing unit 54 forms a plurality of divided areas B by dividing a rendering area A for lighting rendering into a plurality of areas. For example, the data processing unit 54 forms a plurality of divided areas B by dividing the rendering area A into a lattice. Each divided area B has a rectangular shape and is provided in a matrix on the screen without gaps. One divided area B includes one or more lighting fixtures 10 . It should be noted that the divided area B also includes a blank area in which the lighting device 10 is not included.

The data processing unit 54 groups one or more lighting fixtures 10 arranged in each of the plurality of divided regions B to generate a lighting fixture group G. FIG. When generating the lighting fixture group G, the data processing unit 54 generates the lighting fixture group G such that the number of lighting fixtures 10 included in the lighting fixture group G is equal to or less than a predetermined threshold. The predetermined threshold is a value determined by the computing power of the processing terminal 50, and is set to an appropriate value within a range of 10 or more and 20 or less, for example.

4A shows 16 divided areas B on the display section 57. FIG. In the figure, eight lighting fixtures 10 are included in the divided area B11, and a lighting fixture group G11 made up of the eight lighting fixtures 10 is generated. Also, 13 lighting fixtures 10 are included in the divided area B14, and a lighting fixture group G14 consisting of 13 lighting fixtures is generated. For example, when the predetermined threshold is set to 10 units, in FIG. , the data processing unit 54 further divides and subdivides the effect area A.

FIG. 4(b) shows 64 divided regions B that are further divided. In the figure, the number of lighting fixtures 10 in all of the divided areas B, that is, in all of the lighting fixture groups G is equal to or less than the predetermined threshold.

On the other hand, when the number of lighting fixtures 10 included in the lighting fixture group G is extremely smaller than the predetermined threshold, the data processing unit 54 integrates the plurality of lighting fixture groups G so as not to reduce the efficiency of data processing. , regenerate the luminaire group Ga. For example, when the total number of lighting fixtures 10 included in a plurality of lighting fixture groups G is equal to or less than a predetermined threshold, the data processing unit 54 integrates the lighting fixture groups G into one lighting fixture group. Regenerate as Ga.

FIG. 5 is a diagram showing an example of integrating a plurality of divided regions B. FIG.

In FIG. 5, 64 divided areas B are shown on the display section 57 . In the figure, three lighting fixtures are included in the lighting fixture group G11 corresponding to the divided area B11, and three lighting fixtures are included in the lighting fixture group G21 corresponding to the divided area B21. Also, one lighting fixture is included in the lighting fixture group G12 corresponding to the divided area B12, and one lighting fixture is included in the lighting fixture group G22 corresponding to the divided area B22. The total number of lighting fixtures 10 included in the lighting fixture groups G11, G12, G21 and G22 is eight.

For example, when the predetermined threshold is set to 10 units, the data processing unit 54 regenerates one lighting fixture group Ga by integrating the lighting fixture groups G11, G12, G21 and G22 adjacent to each other. . Note that the data processing unit 54 may integrate a plurality of lighting fixture groups G while maintaining the aspect ratio of the divided areas B so that the divided areas B after integration have similar shapes. Also, the data processing unit 54 does not necessarily need to integrate the lighting fixture groups G that are adjacent to each other, and may integrate a plurality of lighting fixture groups G that are scattered on the effect area A.

After generating the lighting fixture group G, the data processing unit 54 performs distributed processing on the data related to the moving image content for each lighting fixture group G to generate the lighting control data d. Distributed processing includes processing for extracting color information from pixel information of moving image content. Note that the processing related to moving image content may include processing for extracting luminance information and display schedule information from pixel information of moving image content. The data processing unit 54 generates lighting control data d based on the color information and the like extracted by this distributed processing. The lighting control data d is generated based on a communication standard (for example, DMX standard) required for communication control of the lighting fixture 10 .

The control unit 55 controls the plurality of lighting fixtures 10 based on the lighting control data d. Specifically, the control unit 55 outputs the lighting control data d generated by the data processing unit 54 in real time, thereby controlling light emission of the plurality of lighting fixtures 10 . Alternatively, the control unit 55 stores the lighting control data d generated by the data processing unit 54 in the storage unit 52 and reads out the stored lighting control data d from the storage unit 52, thereby controlling the light emission of the plurality of lighting fixtures 10. to control. The control unit 55 is implemented by, for example, a microcomputer, but may be implemented by a processor.

The control unit 55 transmits the lighting control data d to the plurality of lighting fixtures 10 via the communication unit 51 and the wide area communication network 70 . Each lighting fixture 10 that has received the lighting control data d is subjected to dimming control and toning control based on the lighting control data d.

In the lighting system 100 of the present embodiment, the data processing section 54 generates the lighting fixture group G based on the arrangement information of the plurality of lighting fixtures 10 . Then, the data processing unit 54 performs distributed processing on the data regarding the moving image content for each lighting fixture group G, thereby generating the lighting control data d. As a result, it is possible to prevent the process of generating the lighting control data d from becoming heavy.

[Lighting control data generation method]
A lighting control data generation method according to the embodiment will be described.

FIG. 6 is a flowchart showing a lighting control data generation method according to the embodiment.

First, the data processing unit 54 generates a lighting fixture group G based on the arrangement information of the plurality of lighting fixtures 10 .

Specifically, the data processing unit 54 divides the rendering area A to form a plurality of divided areas B (step S11). The first number of divisions is preset by the user. The initial number of divisions is set, for example, so that the division area B is 4 or more.

Next, the data processing unit 54 determines whether or not the number of lighting fixtures 10 arranged in each of the plurality of divided regions B is equal to or less than the first threshold (step S12). The first threshold is a value determined by the computing power of the processing terminal 50, and is set to an appropriate value within a range of 10 or more and 20 or less, for example.

If the number of lighting fixtures 10 in all divided areas B is not equal to or less than the first threshold (No in S12), the data processing unit 54 further divides the effect area A (step S13). The data processing unit 54 repeats steps S12 and S13 until the number of lighting fixtures 10 in all of the divided areas B is equal to or less than the first threshold. If the number of lighting fixtures 10 in all divided areas B is equal to or less than the first threshold (Yes in S12), the next step S14 is executed.

Next, the data processing unit 54 determines whether or not the number of lighting fixtures 10 arranged in each of the plurality of divided regions B is equal to or less than the second threshold (step S14). This step S14 is a judgment item for suppressing an excessive number of lighting fixture groups G due to the initially set number of divisions being too large. The second threshold is a value smaller than the first threshold, and is set to an appropriate value within a range of 5 or more and 8 or less, for example.

When the number of lighting fixtures 10 in all the divided areas B is equal to or less than the second threshold (Yes in S14), the data processing unit 54 roughly divides the effect area A (step S15). The data processing unit 54 repeats steps S14 and S15 until the number of lighting fixtures 10 in all of the divided regions B becomes greater than the second threshold. If the number of lighting fixtures 10 in all divided areas B is greater than the second threshold (No in S14), the next step S16 is executed. Note that steps S14 and S15 are auxiliary steps of steps S12 and S13. is not executed, and the next step S16 is executed.

The data processing unit 54 generates a lighting fixture group G including a plurality of lighting fixtures 10 placed in the divided area B (step S16). As a result, a lighting fixture group G including lighting fixtures 10 whose number is greater than the second threshold and equal to or less than the first threshold is generated.

Next, the data processing unit 54 generates lighting control data d based on the moving image content (step S17). Specifically, when extracting the color information from the pixel information included in the moving image content, the data processing unit 54 extracts the color information by performing distributed processing for each lighting fixture group G, and converts the extracted color information into The lighting control data d is generated based on the above.

By executing steps S11 to S17 in the entire rendering area A, lighting control data d is generated. Note that steps S14 and S15 may be performed before steps S12 and S13. Further, steps S14 and S15 are not necessarily required, and the lighting control data generation method may be configured by steps S11 to S13, S16 and S17. These steps S11 to S17 are automatically executed by the processing terminal 50, but some steps may be executed manually.

Next, another flow executed during the flow shown in FIG. 6 will be described. In this example, an example of integrating a plurality of lighting fixture groups G will be described.

FIG. 7 is a diagram showing another flow performed during the flow shown in FIG. 6; Another flow is performed between steps S16 and S17 described above.

The data processing unit 54 determines whether or not there is a case where the total number of lighting fixtures 10 included in a plurality of lighting fixture groups G is equal to or less than the first threshold in the effect area A (step S16A). ). If there is no case where the total number of lighting fixtures 10 included in a plurality of lighting fixture groups G is less than or equal to the first threshold value (No in S16A), the plurality of lighting fixture groups G is not integrated. Then, the process proceeds to step S17.

If there is a case where the total number of lighting fixtures 10 included in a plurality of lighting fixture groups G is equal to or less than the first threshold value (Yes in S16A), the data processing unit 54 determines that the plurality of lighting fixture groups G are integrated (step S16B). For example, the data processing unit 54 regenerates one lighting fixture group Ga by integrating lighting fixture groups G11, G12, G21 and G22 adjacent to each other. For example, the data processing unit 54 integrates the plurality of lighting fixture groups G while maintaining the aspect ratio of the divided area B so that the area after integration has a similar shape to the divided area B before integration. Note that the data processing unit 54 may integrate a plurality of lighting fixture groups G based on the aspect ratio of the divided regions preset by the user.

The lighting fixture group G is integrated by executing steps S16A and S16B. These steps S16A and S16B are automatically executed by the processing terminal 50, but the integration process in step S16B, for example, may be executed manually.
