Background Technology

[0002] In the field of lighting control, most adjustments still rely on manual methods based on the experience of staff. In this method, staff typically adjust the color parameters of the lights, such as RGB values ​​and color temperature, manually based on their own experience and visual perception. For example, when setting up stage lighting, staff might roughly adjust the color of the lights according to the atmosphere required for the performance scene to create different atmospheres, such as warm, mysterious, or cheerful.

[0003] However, this method relies heavily on the experience and subjective judgment of staff, leading to significant differences in results among different personnel and making it difficult to achieve precise and uniform lighting color control. Furthermore, manual adjustments are difficult and inefficient for complex color requirements, thus failing to meet diverse lighting effect demands. Summary of the Invention

[0071] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0072] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0073] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more (including two), similarly, "multiple sets" refers to two or more sets (including two sets), and "multiple pieces" refers to two or more pieces (including two pieces) unless otherwise explicitly defined.

[0074] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0075] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0076] In the current field of lighting control, technicians generally rely on two methods: one is to adjust the lighting based on their own accumulated experience, and the other is to implement lighting settings by referring to existing color charts. However, both methods have significant drawbacks.

[0077] Lighting control methods based on personal experience inevitably introduce errors due to their strong subjectivity and lack of quantifiable standards. Moreover, the varying levels of experience among different technicians complicate the lighting control process and make it difficult to control, significantly increasing the difficulty of lighting control.

[0078] On the other hand, existing color charts are designed primarily based on the final visual effect presented by light scattering, rather than starting from the physical characteristics of the light itself. This design approach makes it difficult for color charts to accurately match lighting parameters in practical applications, thus affecting the precision of lighting and failing to meet the needs of scenarios with high precision requirements for lighting effects.

[0079] To address the aforementioned technical issues, this application innovatively proposes a complete system for constructing and applying a digital color library for lighting. Specifically, this application pioneeringly provides a method for constructing a digital color library for lighting. This method focuses deeply on the color characteristics of lighting itself (such as core elements like brightness, hue, and chroma), and can accurately create a highly adaptable digital color library for lighting based on diverse user-defined needs.

[0080] Building upon this foundation, this application further proposes a color recognition and encoding scheme based on the digital color library for lighting. This scheme enables precise identification of colors within the color library and assigns them unique encoding identifiers, providing a clear and accurate data foundation for subsequent lighting control.

[0081] Furthermore, this application creatively designs a lighting control method based on the aforementioned coding. This method is simple, convenient, and efficient. Users only need to code to quickly and accurately control the lights, greatly improving the efficiency and accuracy of lighting control and bringing a brand-new solution to the field of lighting control.

[0082] Example 1

[0083] like Figure 1 As shown, some embodiments of this application provide a method for constructing a digital color library for lighting, which includes:

[0084] S101. Determine the target color brightness corresponding to the lighting application scenario requirements.

[0085] S102. Determine the target color system that is compatible with the lighting display characteristics.

[0086] S103. Extract multiple hues from the target color system based on the target color brightness.

[0087] S104. Generate a digital color library for lighting based on preset color library generation requirements and multiple hues.

[0088] In some embodiments, the method for constructing a digital color library for lighting refers to a systematic process or set of steps for creating such a library. This method converts the color characteristics of light (such as brightness, hue, and chroma) into a digital form, facilitating storage, transmission, and processing to meet the needs of various lighting application scenarios.

[0089] In some embodiments, lighting application scenario requirements refer to the specific requirements for lighting effects under different environments or uses. For example, stage performances may require rich and varied lighting effects; museum exhibitions may require soft and uniform lighting to protect exhibits; and commercial spaces may require lighting to create a specific atmosphere. It is evident that these requirements determine the goals and direction of building a digital color library for lighting.

[0090] In some embodiments, target color brightness refers to the lightness or darkness of a color, and is an important parameter describing the color of light. In this method, target color brightness refers to the target color brightness range or specific target color brightness value required for the target application scenario, which needs to be determined in advance. This target color brightness will serve as the basis for subsequent hue extraction and color library generation. Specifically, this target color brightness can be transformed based on the target color system after it has been determined.

[0091] In some embodiments, lighting display characteristics refer to the physical and chemical properties of lighting equipment when displaying colors, such as color temperature, color rendering index, and luminous efficacy. Different lighting equipment may have different display characteristics, which can affect the color presentation. Therefore, when constructing a digital color library for lighting, it is necessary to select a colorimetric system that is compatible with the lighting display characteristics to ensure that the colors in the digital color library can be accurately output by the target lighting equipment.

[0092] In some embodiments, the target colorimetric system is a specific color model or standard system selected based on the display characteristics of the lighting during the construction of a digital color library for accurately describing and representing the colors of the lighting. The Munsell colorimetric system can classify colors using hue, lightness, and chroma; the CIE colorimetric system describes colors using stimulus values ​​based on the characteristics of human vision; and the RGB colorimetric system describes colors based on the additive color mixing principle of the three primary colors. It is evident that different colorimetric systems have different principles and applicable scenarios. When constructing a color library, the selection must be combined with the display characteristics of the lighting equipment (such as color gamut and color reproduction capability). If the lighting is used for stage performances, a colorimetric system capable of displaying rich colors can be selected; if used for industrial testing, a system based on scientific measurement standards is preferable to ensure that the extracted hue accurately reflects the actual color of the lighting, generating a color library that meets the requirements.

[0093] In some embodiments, hue refers to the basic attribute of color, such as red, orange, yellow, green, blue, indigo, and violet. In the construction of a digital color library for lighting, multiple hues are extracted from the target color system based on the target color brightness. These hues will constitute the basic color set of the digital color library for lighting.

[0094] In some embodiments, preset color library generation requirements refer to a set of rules or standards that must be followed when generating a digital color library for lighting. These requirements may include the number, distribution, and uniformity of hues, as well as the storage format and access method of the color library. Preset color library generation requirements help ensure that the generated color library meets the needs of practical applications and has good usability and scalability.

[0095] In some embodiments, a digital color library for lighting refers to a digital collection containing multiple lighting colors generated by the above-described construction method. Each color in the color library can be represented by a specific code or identifier, facilitating its retrieval and management within the lighting control system. Therefore, the construction of a digital color library for lighting provides strong support for precise control and rapid switching of lighting effects.

[0096] For example, in the scenario of constructing a digital color library for stage lighting, this method can be based on the target color brightness corresponding to the needs of the lighting application scenario, such as a target color brightness of 8-10 for a lively atmosphere; a target color brightness of 3-5 for a warm atmosphere; and a target color brightness of 5-8 for a dynamic performance atmosphere.

[0097] At this point, since the stage lighting equipment has strong color performance and a wide color gamut, this method selects the Munsell color system, which can present rich colors.

[0098] Then, within each target color brightness range, the method extracts multiple suitable hues from the Munsell color wheel, such as red (warm atmosphere), warm yellow (cozy atmosphere), and blue (dynamic performance atmosphere).

[0099] Finally, based on the requirements that the color library should include a variety of ambient colors and be easy to access quickly, the extracted hues are encoded or presented directly to generate a digital color library for stage lighting.

[0100] For example, in the process of constructing a digital color library for the lighting of museum artifact exhibitions, this method can determine the target color brightness of the display case lighting to be 20-40 and the target color brightness of the wall display area to be 40-60 in order to protect the artifacts from damage by strong light and ensure that visitors can see them clearly.

[0101] Then, based on the requirements of museum lighting for accurate color reproduction, the CIE1931-XYZ color system can be selected.

[0102] Furthermore, this method can extract soft, neutral hues, such as off-white and light wood color, from the CIE color system at the target color brightness.

[0103] Finally, based on the requirement that the color library should meet the requirements of accurate color and soft light for the display of cultural relics, the hue codes will be extracted to generate a digital color library for the lighting of museum cultural relic exhibitions.

[0104] In these embodiments, the method can accurately determine the target color brightness corresponding to the lighting application scenario requirements, ensuring that the generated color library closely matches the actual usage scenario and avoiding lighting effect deviations caused by improper target color brightness settings. By selecting a suitable target colorimetric system based on the lighting display characteristics, the hues extracted from this system accurately reflect the actual colors displayed by the lighting equipment, greatly improving the accuracy and consistency of color description and effectively solving the lighting accuracy problem of traditional color cards based on light scattering results. Simultaneously, extracting multiple hues based on the target color brightness enriches the color library's color variety, providing a wider range of choices for lighting design and meeting diverse creative needs. Finally, combining preset color library generation requirements, multiple hues are integrated to generate a digital color library, achieving standardized and digital management of lighting colors, facilitating storage, transmission, and retrieval, making lighting control simpler, more convenient, and more efficient. This helps reduce the difficulty and error of lighting control, thereby promoting the development of the lighting control field towards precision and intelligence.

[0105] To make the constructed digital color library of lighting easily recognizable by the human eye, in some embodiments, the target color brightness corresponding to the requirements of the lighting application scenario is determined, including:

[0106] Based on the requirements of lighting application scenarios, including the optimal color discrimination requirements of the human eye, the target color brightness is determined.

[0107] In some embodiments, since the human eye's ability to distinguish colors is affected by color brightness, the human eye's ability to differentiate different colors and perceive color details will vary under different brightness conditions. Therefore, there exists a specific brightness (or brightness range) within which the human eye can most clearly and accurately distinguish various colors. This brightness (or brightness range) is the target color brightness (or target color brightness interval) corresponding to the human eye's optimal color discrimination requirements.

[0108] In some embodiments, the method can determine the target color lightness when the human eye has the highest color resolution (i.e., the human eye can distinguish the most colors on the color plane) within the Munsell system's lightness range of 0-10, and the target color lightness is Munsell system lightness 5.

[0109] For example, in a small indoor folk music concert, the stage setup is warm and simple, and the lighting aims to create a soothing and tranquil atmosphere, allowing the audience to immerse themselves in the music. In the Munsell system, a light intensity of 5 is soft and non-glaring, neither too bright nor disrupting the tranquility of the venue, while still clearly showing the singer's silhouette and simple props. At this intensity, the human eye can effectively distinguish warm wood tones and pale yellow hues commonly used in folk music performances, perceiving the warmth and comfort conveyed by these colors. Based on the optimal color discrimination requirements of the human eye, the target color intensity for this stage lighting application scenario is determined to be 5 in the Munsell system. This allows for the construction of a digital color library for lighting, helping to create the perfect performance atmosphere.

[0110] In these embodiments, the method significantly improves the accuracy and practicality of color library construction. When constructing a digital color library for lighting, brightness may be determined only from a broad perspective, such as creating scene atmosphere, without fully considering the human eye's color discrimination characteristics. This results in a color library that, while meeting basic lighting and atmosphere requirements in practical applications, may not allow the human eye to accurately and clearly distinguish the colors presented by the light, affecting the visual experience. However, by incorporating this constraint, when determining the target color brightness, the method fully considers at which the human eye's color discrimination ability is strongest. The target color brightness determined based on this ensures that the light color is presented to the observer in the clearest and most accurate way. The resulting digital color library for lighting, in practical applications whether for stage performances, commercial displays, or other scenarios, ensures superior lighting color effects, greatly improving the quality and effect of lighting control and providing lighting designers with a higher-quality and more practical tool.

[0111] To improve the accuracy of the constructed digital color library for lighting, in some embodiments, the target color brightness is determined based on the optimal color discrimination requirements of the human eye, which are included in the lighting application scenario requirements. This includes:

[0112] Based on the lighting display effect requirements and the human eye's optimal color discrimination requirements included in the lighting application scenarios, the target color brightness was determined.

[0113] In some embodiments, lighting display effect requirements refer to the specific visual presentation requirements that lighting needs to achieve in different application scenarios. For example, in commercial stores, lighting display effect requirements may involve using bright and vibrant lighting to highlight the color, texture, and details of merchandise; in theater stages, lighting display effect requirements may involve achieving rich color variations, strong contrasts in brightness and darkness, and clever shaping of light and shadow according to the development of the plot and the rhythm of the performance, thereby enhancing the artistic appeal and visual impact of the stage and guiding the audience's emotions and attention; in museum exhibition halls, lighting display effect requirements are to provide soft, uniform, and color-accurate lighting that can clearly display the details of cultural relics or artworks while avoiding damage to the exhibits from strong light, creating a tranquil and solemn visiting atmosphere so that visitors can focus on appreciating the exhibits.

[0114] For example, in a small immersive poetry reading stage, the lighting effect needs to create a tranquil and poetic atmosphere. The light needs to be soft, neither glaring and disruptive to the atmosphere, nor dim and affecting visual presentation. It should be able to outline the reciter's silhouette and make the background appear and disappear. Considering the optimal color discrimination requirements of the human eye, a brightness value of 5 in the Munsell system is suitable. It avoids glare affecting color discrimination and prevents excessive darkness from losing color details. It allows the elegant color matching on the stage to be harmonious and layered. Therefore, the target color brightness for this scene is determined to be 5 in the Munsell system.

[0115] In these embodiments, the method ensures that the selected light color precisely matches the unique needs of different scenarios during the selection process. For example, in an art exhibition setting, appropriate color brightness allows the selected light color to perfectly highlight the colors and details of the exhibits, creating a visual atmosphere that matches the art theme. On a commercial performance stage, appropriate color brightness can create dazzling, soft, or stunning lighting effects based on the performance style, greatly enhancing the performance's appeal and entertainment value. Simultaneously, fully considering the human eye's optimal color discrimination requirements ensures that the colors presented by the light are clearly and accurately perceived by the human eye, thus avoiding color distortion and blurring caused by inappropriate brightness, thereby improving the comfort and accuracy of the visual experience. In summary, the target color brightness determined by combining both methods not only optimizes the lighting effect but also ensures accurate color presentation.

[0116] To select a suitable color system, in some embodiments, a target color system adapted to the characteristics of the light display is determined, including:

[0117] Based on the requirements for color accuracy, color space richness, and human visual perception of the lighting display, a target color system is determined from a pre-set color system library.

[0118] In some embodiments, the color accuracy requirement of lighting displays refers to the requirement that the colors presented by the lights must reproduce the colors expected by the designer or user as accurately as possible in the lighting application scenario. For example, in stage lighting design, the lights need to accurately present specific clothing colors and prop colors to create the expected stage atmosphere. Therefore, the color accuracy requirement emphasizes the closeness between the light colors and the true colors, and is one of the important indicators for measuring the quality of lighting displays.

[0119] In some embodiments, a color space refers to a mathematical model used to describe and represent color, which defines the relationships and ranges between the three basic attributes of color (such as hue, chroma, and lightness). Different color spaces have different characteristics and applicable ranges.

[0120] In some embodiments, the richness requirement refers to the need for the color system in lighting displays to cover the widest possible color gamut to meet the diverse color needs of various complex scenarios. For example, in some artistic creations and high-end displays, it may be necessary to use some very unique, vibrant, or subtle colors. This requires the color space defined by the color system to be large enough to accommodate these rich colors, providing lighting designers with more creative possibilities.

[0121] In some embodiments, the human eye is the organ that ultimately receives and perceives the color of light. The requirement for optimal human eye perception emphasizes that the color representation system must fully consider the perceptual characteristics of the human eye. A good color representation system should enable the colors displayed by the light to conform as closely as possible to the visual perception habits of the human eye, allowing the observer to comfortably and accurately perceive the color information conveyed by the light. For example, it should avoid situations where the colors are too glaring, the contrast is too strong or too weak, leading to visual fatigue or color perception distortion.

[0122] In some embodiments, a preset color system library refers to a pre-collected and organized set of various color systems. These color systems may be developed based on different theories, standards, or application requirements, such as the Munsell color system, the RGB color system, and the CMYK color system. The preset color system library provides a wide range of choices for determining a target color system. By evaluating and comparing the various color systems in the library, this method can identify the most suitable color system for the current lighting display requirements.

[0123] For example, in the application scenario of preparing for a large-scale musical performance, the actors' costumes on stage include gorgeous red costumes and deep blue capes. The lighting needs to accurately reproduce these colors to avoid color differences affecting the quality of the performance. Simultaneously, when facing scenes ranging from a dreamlike forest to a mysterious palace, the lighting needs to present a variety of delicate, unique, and rich colors to create a realistic atmosphere. Furthermore, the lighting must ensure that the human eye can comfortably and accurately perceive colors at different positions and for different durations. Considering these requirements, after comparing and selecting from various pre-set color system libraries, the Munsell color system, with its precise color definitions, rich color gradations, and characteristics consistent with human visual perception, was ultimately selected as the target color system suitable for the stage lighting display characteristics of this project.

[0124] In these embodiments, the method ensures that the color presented by the light is highly consistent with the preset color accuracy; it allows the light to display more diverse and delicate colors in terms of color space richness; and considering the effects of human eye perception, it enables the light color to be perceived comfortably and accurately under different environments and viewing conditions, reducing visual fatigue and improving the viewing experience. By comprehensively considering these requirements and determining the target color system from a preset color system library, a scientific and precise basis is provided for lighting design, ensuring the high quality and stability of the lighting display.

[0125] To refine the foundation for constructing the color library, in some embodiments, when the target color system is the Munsell color system and the target color lightness is 5 in the Munsell color system, multiple hues are extracted from the target color system based on the target color lightness, including:

[0126] Based on a value of 5, 40 visually equidistant hues were extracted from the Munsell color system.

[0127] In some embodiments, the Munsell color system refers to a color representation system proposed by the American artist and teacher Ah. Munsell in 1905. It systematically and quantitatively describes the three attributes of color—hue, value, and chroma. Specifically, the Munsell color system divides the color wheel into 10 primary hues, each of which is further subdivided into 10 equal parts, resulting in a total of 100 hues. Values ​​range from 0 (black) to 10 (white), with a value of 5 in the middle, representing a medium level of color brightness. Chroma reflects the purity or vividness of a color; the higher the value, the more vivid the color; the lower the value, the closer the color is to gray. Thus, the Munsell color system, through this three-dimensional coordinate system, can accurately describe and locate each color.

[0128] In some embodiments, a color brightness of 5 is neither too bright and glaring as high color brightness, nor too dark as low color brightness. A brightness of 5 is a commonly used choice in scenarios where a balance between color representation and visual comfort is required. For example, in stage lighting, a color brightness of 5 can be used as a base color brightness to construct a color library capable of representing rich stage effects.

[0129] In some embodiments, visual equidistance refers to the fact that, in human visual perception, the degree of difference between these extracted hues is equal. That is, when the human eye observes these hues, it perceives the color variations between them as uniform and consistent. For example, on a color wheel, if hues are selected according to certain intervals and rules so that the visual difference between two adjacent hues is approximately the same, then these hues are visually equidistance.

[0130] For example, the 40 hues can be 5R, 7.5R, 10R, 2.5YR, 5YR, 7.5YR, 10YR, 2.5Y, 5Y, 7.5Y, 10Y, 2.5GY, 5GY, 7.5GY, 10GY, 2.5G, 5G, 7.5G, 10G, 2.5BG, 5BG, 7.5BG, 10BG, 2.5B, 5B, 7.5B, 10B, 2.5PB, 5PB, 7.5PB, 10PB, 2.5P, 5P, 7.5P, 10P, 2.5RP, 5RP, 7.5RP, 10RP, and 2.5R in the Munsell color system.

[0131] In these embodiments, the method can fully meet the design, matching and application needs of color diversity in different scenarios with a rich and systematic color set, and can also ensure that each hue presents a balanced difference effect in visual perception through the visually equidistant and uniform distribution characteristics, avoiding abrupt color transitions, and providing strong support for the accurate expression and harmonious presentation of colors.

[0132] To fully represent color, in some embodiments the method further includes:

[0133] The saturation of each of the 40 hues was extracted from the Munsell color system.

[0134] In some embodiments, the saturation of a hue refers to the Munsell chroma corresponding to the light color. Specifically, it can refer to the color purity or vividness of the corresponding hue at a specific color brightness (such as a color brightness of 5). It reflects the degree to which the color deviates from neutral gray. This saturation is usually quantified by a saturation numerical value (where a larger value represents higher saturation and more vivid color). Each hue corresponds to a different saturation value due to its different color components and saturation. For example, red hues may have different levels of saturation values ​​from low to high, corresponding to different levels of vividness such as light pink, true red, and deep red.

[0135] In these embodiments, the method can accurately quantify the vividness of each hue at a specific color brightness, construct a color database containing both hue and saturation dimensions, and provide more detailed parameter basis for color design.

[0136] To illustrate the composition of the digital color library for lighting in detail, in some embodiments, a digital color library for lighting is generated based on preset color library generation requirements and multiple hues, including:

[0137] Based on the preset color library generation requirements, 40 hues and their respective saturations, a digital color library for lighting is generated.

[0138] In these embodiments, the method can accurately construct a comprehensive and precise lighting color database. By integrating hue and saturation information, it can not only meet the needs of different scenarios for color types (hue), but also accurately control the vividness (saturation) of colors. This provides highly customized color selection solutions for lighting design, ensuring accurate color expression and perfect artistic effect in different application scenarios (such as stage lighting, landscape lighting, etc.), while improving the standardization and digitalization of color management.

[0139] In order to build a more suitable digital color library for lighting, in some embodiments, the preset color library generation requirements include at least color library structure requirements, hue hierarchy requirements, display layout requirements, and element association requirements.

[0140] In some embodiments, the color library structure requirement refers to the need to clearly define the overall architecture of the color library when generating a digital color library for lighting, including the hierarchical division of color parameters such as hue, saturation, and brightness. A reasonable color library structure helps improve the manageability, scalability, and efficiency of color data, ensuring that users can quickly locate and obtain the color information they need.

[0141] In some embodiments, the hue hierarchy requirement refers to the hierarchical division of hues in a color library, that is, a hue classification method from macro to micro, from broad to specific. A reasonable hue hierarchy division can meet the color precision requirements of different application scenarios, improving the flexibility and accuracy of color selection.

[0142] In some embodiments, display layout requirements refer to the standardization of how color information is presented in the display or interactive interface of a color library, including the arrangement of color samples, the position of color names or numbers, and the display format of color parameters. A good display layout can improve the user experience, enabling users to intuitively and quickly browse and compare different colors, while also facilitating color selection, editing, and saving operations.

[0143] In some embodiments, element association requirements refer to specifying the way color elements are associated with other relevant information (such as saturation, color name, color code, etc.) in a color library. Clear element associations enhance the usability and guidance of the color library, helping users better understand and apply color information.

[0144] In these embodiments, the method can ensure that color data is organized and stored in a logical and systematic way through clear color library architecture design requirements, which helps to ensure the balanced distribution and hierarchy of hues, and thus form a digital color library that combines scientific classification, convenient operation and application guidance value, significantly improving the efficiency and professionalism of color management.

[0145] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below. In some embodiments, such as Figure 2 As shown, the method for constructing this digital color library of lights includes:

[0146] S201. Based on the lighting display effect requirements and the human eye's optimal color discrimination requirements included in the lighting application scenario, determine the target color brightness.

[0147] S202. Based on the requirements for color accuracy, color space richness, and human visual perception of the lighting display, the Munsell color system is determined from the preset color system library.

[0148] S203. In the Munsell color system, the target color lightness is 5. Based on the lightness of 5, 40 visually equidistant hues are extracted from the Munsell color system.

[0149] S204. Extract the saturation of each of the 40 hues from the Munsell color system.

[0150] S205. Based on the color library structure requirements, hue hierarchy requirements, display layout requirements, element association requirements, and the saturation of each of the 40 hues, generate a digital color library for lighting.

[0151] Example 2

[0152] like Figure 3 As shown, some embodiments of this application provide a light color encoding method based on a digital light color library. The digital light color library is constructed using the method described in Embodiment 1. The light color encoding method based on the digital light color library includes:

[0153] S301. Determine the color of the light to be encoded.

[0154] S302. Identify the basic hue of a light color based on a digital color library for light.

[0155] S303. Determine the subdivided hue based on the light color and basic hue.

[0156] S304. Determine the saturation level based on the light color and subdivided hue.

[0157] S305 generates color codes based on basic hue, subdivided hue, and saturation levels.

[0158] In some embodiments, the light color to be encoded refers to a specific light color that needs to be color encoded. This light color may be a color collected from the actual scene, or it may be a color specified according to design requirements.

[0159] In some embodiments, the basic hue refers to the primary hue category to which the light color belongs. In a digital color library for light, the basic hues are the 10 basic hues in the Munsell color system.

[0160] In some embodiments, subdivision hue refers to a hue category that is further subdivided from the basic hue. In the digital color library of lighting, subdivision hue refers to the 40 subdivision hues in the Munsell color system.

[0161] In some embodiments, saturation level refers to the vividness or purity of a light color. In a digital light color library, saturation level is associated with subdivision hues, each subdivision corresponding to a different number of saturation levels used to encode and distinguish light colors with different levels of vividness.

[0162] In some embodiments, color encoding refers to the process of converting light color into a specific format or code. Through encoding, various attributes of light color (such as basic hue, subdivision hue, saturation level, etc.) can be represented in digital form, making it easier for the system or user to identify, process, and apply them.

[0163] In these embodiments, the method can quickly lock the color range by using the macro-classification of basic hues in the color library, and improve the accuracy of color recognition by double verification of subdivided hue and saturation levels. Finally, it generates an encoding system containing multi-dimensional color parameters, which effectively solves the problems of ambiguity and ineffective retrieval in traditional color recognition. Thus, it provides a unified and scalable color identification scheme for lighting control systems, which significantly improves the accuracy and efficiency of lighting design, scene switching and cross-device color management.

[0164] To more comprehensively apply light color encoding, in some embodiments, determining the light color to be encoded includes:

[0165] The color of the target light is detected by a spectrometer; or

[0166] The color of the target light is determined based on the light output requirements.

[0167] In some embodiments, a spectrometer is an instrument used to measure and analyze the wavelength and intensity distribution of light. In light color detection, a spectrometer can capture the light emitted by a target light source and decompose it into light components of different wavelengths, thereby accurately determining the color characteristics of the light, such as color temperature, color rendering index, and specific spectral distribution.

[0168] In some embodiments, target light refers to a specific light that needs to be detected or identified. In the context of this application, target light is a light object to be color-coded. It can be any type of light, such as LED lights, fluorescent lights, halogen lights, etc., or it can be lighting in a specific scene or application.

[0169] In some embodiments, lighting output requirements refer to the expected values ​​or specifications set for parameters such as light color, brightness (which is conceptually different from the aforementioned chromatic alumina), and color temperature, based on specific application scenarios or design requirements. When determining the light color of the target light, the color of the light can be selected or set according to the expected visual effect, atmosphere creation, or functional requirements. For example, in stage lighting design, it may be necessary to set different colored lights according to the needs of the plot to create a specific emotional atmosphere.

[0170] In some embodiments, the difference between brightness and lightness is explained as follows: Brightness is a physical concept, mostly used to represent the intensity of light reflected from the surface of an object, and is measured in candela per square meter (nits). In fields such as lighting and photography, it is used to control lighting effects and adapt to ambient light, and is affected by the luminous intensity of the light source and the reflectivity of the object. However, lightness is a color science concept, used to reflect the lightness or darkness of a color. It is related to color characteristics and human visual perception, and is used in art fields such as painting and design to create layers and guide the eye. Different hues have different lightness and can be altered by adding black and white.

[0171] For example, the built-in sensor of the spectrometer converts and analyzes the light signal of the target light. After processing by the internal algorithm, the color parameters of the light are directly displayed on the instrument's screen, such as color temperature (e.g., 3000K, representing warm white), spectral curve (intuitively showing the intensity distribution of light at each wavelength), and RGB values ​​(e.g., R:255, G:200, B:100, representing the proportion of the three primary colors of red, green, and blue). The color of the light can be accurately determined by these data.

[0172] For example, a user might want to control the output of a light in the color "Vibrant Orange." Here, "Vibrant Orange" represents the desired light output.

[0173] In these embodiments, the method can detect the color of the target light using a spectrometer. It can quickly and accurately obtain detailed data on the light at the spectral level, such as color temperature and spectral distribution, through scientific and precise instrumental analysis, thereby accurately determining the light color and avoiding errors caused by subjective human judgment. Furthermore, determining the color of the target light based on light output requirements gives users the ability to flexibly and directly specify the required light color according to specific application scenarios, emotional atmosphere, or functional purposes, meeting personalized and diverse lighting design needs. The combination of these two methods ensures both the accuracy of color judgment and the flexibility in practical applications, greatly improving the efficiency and quality of light color application.

[0174] To define the basis of the encoding and ensure its effectiveness, in some embodiments, the digital color library of light includes a basic hue wheel composed of multiple basic hues, a subdivided hue wheel composed of multiple subdivided hues, and a saturation wheel corresponding to each subdivided hue.

[0175] In some embodiments, the basic hue wheel, the subdivided hue wheel, and the saturation wheel refer to a method of representing a digital color library of light in three rings.

[0176] For example, the basic color wheel is based on the five primary colors of Munsell hues: red (R), yellow (Y), green (G), blue (B), and purple (P), and the five intermediate colors: red-yellow (RY), yellow-green (YG), blue-green (BG), purple-blue (PB), and purple-red (PR). Please see [link / reference]. Figure 4 , Figure 4 A basic hue wheel consisting of 10 basic hues is shown. This hue wheel is obtained by dividing the circumference into 10 equal parts, and it includes a total of 10 basic hues.

[0177] For example, each basic hue is further divided into four levels, resulting in 40 sub-hues. For instance, red can be divided into 100R, 75R, 50R, and 25R. Please refer to... Figure 5 , Figure 5 A subdivided hue wheel consisting of 40 subdivided hues is shown.

[0178] For example, this method divides saturation into 20 equal parts from low to high, represented by even numbers: 02 is the lowest and 40 is the highest, with higher values ​​indicating higher vibrancy. Furthermore, the upper limit of saturation varies depending on the specific hue; for example, the highest saturation value for blue is 16 (8 levels). Please refer to [link / reference]. Figure 6 , Figure 6 A schematic diagram of a saturation ring is shown, in which the upper limit of saturation is 14 (7 grids), and the currently selected saturation is 10.

[0179] In some embodiments, the 40 subdivisions of hue can achieve a maximum saturation of 38 (19 subdivisions, 20 subdivisions in total).

[0180] For example, Figure 7 A schematic diagram of a digital color library for lighting is shown.

[0181] In these embodiments, the digital color library for lighting provides a macro framework for color classification by constructing a basic hue ring composed of multiple basic hues, facilitating the rapid identification of major color categories. A subdivided hue ring, composed of multiple subdivided hues, further refines the color granularity, accurately distinguishing similar hues and meeting the need to identify subtle color differences. The corresponding saturation ring for each subdivided hue fully presents the distribution of different saturation levels, providing a clear quantitative standard for the vibrancy of lighting colors. The synergistic effect of these three elements provides a comprehensive and refined color reference system for lighting color coding, retrieval, matching, and application, effectively improving the scientific nature and accuracy of lighting color management.

[0182] To effectively obtain basic hue, subdivided hue, and saturation levels, in some embodiments, the basic hue of a light color is identified based on a digital color library of light, including:

[0183] Determine the primary hue that is most similar to the color of the light in the basic color wheel;

[0184] Based on the light color and basic hue, determine the subdivided hues, including:

[0185] In the subdivision hue wheel, identify multiple target subdivision hues under the basic hue, and among the multiple target subdivision hues, identify the subdivision hue that is most similar to the light color;

[0186] Based on the color of the light and its subdivided hue, the saturation level is determined, including:

[0187] Determine the saturation level that is most similar to the light color in the saturation circle corresponding to the subdivision color.

[0188] In some embodiments, the basic hue wheel refers to the fundamental structure used for color classification in a digital color library of lights, which consists of multiple basic hues. These basic hues are arranged in a certain order to form a circular system that covers the main categories of colors. During the light color recognition process, the basic hue wheel acts as a macro-classification tool, helping to quickly pinpoint the approximate hue range to which the light color belongs, providing a basic direction for subsequent more accurate color analysis, and making the color recognition process more organized and systematic.

[0189] In some embodiments, light color refers to the specific color characteristics exhibited by the target light, which includes multiple color attributes such as hue, brightness, and chroma. In practical applications, light color can vary due to factors such as the type of light source, the light-emitting principle, and environmental factors.

[0190] In some embodiments, a subdivided hue wheel refers to a color structure that is further refined based on the basic hue wheel, consisting of multiple subdivided hues. The subdivided hue wheel deeply divides each basic hue, subdividing the originally broad basic hue into more specific hue categories. In the process of light color coding, once the basic hue to which the light color belongs is determined, the subdivided hue wheel comes into play. By identifying multiple target subdivided hues under the basic hue and finding the subdivided hue most similar to the light color, it achieves a more precise hue positioning of the light color, improving the accuracy of color recognition.

[0191] In some embodiments, a subdivided hue refers to a specific color unit within a subdivided hue wheel, representing a further subdivision of the basic hue. Each subdivided hue possesses unique color characteristics and exhibits subtle differences from adjacent subdivided hues. In color coding based on a digital color library for lighting, subdivided hue is a crucial parameter describing the hue attributes of lighting colors. By identifying the subdivided hue most similar to the lighting color, the hue characteristics of the lighting color can be described more accurately, providing key information for generating precise color codes and resulting in a more refined and accurate digital representation of lighting colors.

[0192] In some embodiments, the saturation ring refers to a color representation system corresponding to subdivision colors, used to quantify the vividness of colors. In the saturation ring, different positions represent different saturation levels; a higher saturation level indicates a more vivid color, while a lower saturation level indicates a more muted color. During light color coding, after determining the subdivision hue of the light color, the saturation ring is used to determine the saturation level most similar to the light color within that corresponding subdivision hue.

[0193] In some embodiments, saturation level refers to a quantitative indicator in the Munsell color system used to measure the vividness of a color. In light color coding, saturation level reflects the vividness of a light color relative to its subdivided hue. By determining the saturation level most similar to the light color in the saturation ring corresponding to the subdivided color, the saturation characteristics of the light color can be accurately described. This parameter is crucial for the digital representation of light color, enabling not only a clear definition of hue but also accurate quantification of vividness. This provides more detailed and accurate color information for lighting control, design, and other fields, facilitating richer lighting effects and more precise color matching.

[0194] In these embodiments, the method first locates the approximate hue range on the basic hue ring, then precisely locks the subdivided hue on the subdivided hue ring, and finally determines the saturation level on the saturation ring. Together, it achieves comprehensive and accurate identification of light color from macro to micro and from hue to saturation, effectively improving the accuracy and refinement of light color identification. It provides a reliable and accurate color basis for light color coding, control, and application, ensuring that light color can be accurately reproduced and expressed in different scenarios.

[0195] To more accurately determine the basic hue of the light color, in some embodiments, the basic hue most similar to the light color is determined in the basic hue circle, including:

[0196] In the chromaticity diagram, determine the range of color coordinates corresponding to each basic color in the basic color wheel;

[0197] Determine the color coordinates of the light source;

[0198] Identify the target color coordinate range to which the light color coordinates belong;

[0199] The basic hue corresponding to the target color coordinate range is determined as the basic hue to which the light color belongs.

[0200] In some embodiments, a chromaticity diagram refers to a two-dimensional graphic used to represent color characteristics, also known as a chromaticity map or chromaticity coordinate diagram. It uses a specific coordinate system to present the position of colors in a color space in an intuitive graphical way. In a chromaticity diagram, different colors correspond to different coordinate points, which clearly describe the hue, saturation, and other attributes of the colors.

[0201] In some embodiments, the color coordinate range refers to the range of coordinate values ​​corresponding to a specific color region in a chromaticity diagram. For each basic hue in the basic color wheel, it has its own corresponding color region in the chromaticity diagram. This region is composed of a series of color coordinate points, and the range of values ​​for these color coordinate points is the color coordinate range of that basic hue. By determining the color coordinate range, the position and boundaries of different basic hues in the color space can be clearly defined.

[0202] In some embodiments, light color coordinates refer to the specific coordinate values ​​used to represent the position of the target light color in a chromaticity diagram. During light color analysis, the coordinate information of the light color in the color space can be obtained through specific measurement equipment and methods; these coordinate values ​​are the light color coordinates.

[0203] In some embodiments, the target color coordinate range refers to the range of coordinate values ​​for a specific color region corresponding to the light source color coordinates, identified in the chromaticity diagram based on the determined light source color coordinates. Once the light source color coordinates are determined, the specific color region to which the light source color coordinates belong can be found by comparing it with the color coordinate ranges of each basic hue in the basic color wheel. The range of coordinate values ​​corresponding to this region is the target color coordinate range.

[0204] For example, when staff need to identify the basic hue of a new type of LED light, they first determine from the chromaticity chart that the basic hue of red corresponds to a range of color coordinates roughly between (0.65, 0.30) and (0.72, 0.28). Next, they use a spectrophotometer to measure the LED light and determine its color coordinates to be (0.68, 0.29). Then, by comparison, they find that these color coordinates fall within the range of the basic hue of red, thus identifying the target color coordinate range as the range corresponding to red. Finally, they determine the basic hue corresponding to the target color coordinate range as red, meaning the basic hue of this LED light is red.

[0205] For example, a chromaticity diagram can be Figure 8 The CIE1931 chromaticity diagram shown.

[0206] In these embodiments, the method can efficiently and accurately classify light colors at the basic hue level, providing a reliable foundation for subsequent more detailed color analysis and applications, avoiding subjective errors in color classification, and greatly improving the accuracy and scientific nature of light color recognition.

[0207] To more accurately determine the subdivision hue of the light color, in some embodiments, the subdivision hue most similar to the light color is determined from multiple target subdivision hues, including:

[0208] Based on the color coordinates of each target subdivision hue and the preset color tolerance, determine the target color coordinate range corresponding to multiple target subdivision hues;

[0209] Determine the color coordinates of the light source;

[0210] Identify the target color coordinate range to which the light color coordinates belong;

[0211] The target subdivision hue corresponding to the target color coordinate range is determined as the subdivision hue to which the light color belongs.

[0212] In some embodiments, a target subdivision hue refers to a subdivision hue that is likely similar to the target light color, selected from the subdivision hue wheel based on the already determined basic hue. Because there are many subdivision hues, when identifying the subdivision hue to which the light color belongs, the range is first narrowed down based on the basic hue to determine several possible target subdivision hues, and then precise matching is performed among these target subdivision hues.

[0213] In some embodiments, preset color tolerance refers to a parameter used to measure the range of color differences. In actual color recognition and matching processes, due to factors such as measurement errors and the inherent gradation of colors, it is difficult to require the color coordinates of the light color to be completely consistent with those of a subdivided hue. Preset color tolerance is used to set an acceptable range of error; when the difference between the color coordinates of the light color and the color coordinates of a certain subdivided hue is within this preset color tolerance range, the light color is considered to belong to that subdivided hue.

[0214] In some embodiments, the target color coordinate range refers to a coordinate interval determined based on the color coordinates of each target sub-hue and a preset color tolerance. For each target sub-hue, a coordinate range is formed by expanding outward from its color coordinates according to the preset color tolerance; this range is the target color coordinate range. When the light color coordinates of a light color fall within this target color coordinate range, it can be determined that the light color belongs to this target sub-hue.

[0215] For example, when determining the subdivision hue for a warm yellow wall lamp, this method, based on the known basic hue "yellow" in the subdivision hue wheel, filters out three target subdivision hues: "light yellow," "beeswax yellow," and "turmeric yellow." According to the color coordinates of each target subdivision hue, such as "light yellow" (0.42, 0.48), combined with a preset color tolerance of 0.02, its target color coordinate range is determined to be approximately within the range of (0.40-0.44, 0.46-0.50). The color coordinates of the wall lamp light are measured using a spectrophotometer to be (0.41, 0.47). Comparison reveals that these color coordinates fall within the target color coordinate range of "light yellow." Finally, the "light yellow" corresponding to this color coordinate range is determined as the target subdivision hue, meaning the subdivision hue to which the wall lamp light belongs is "light yellow."

[0216] For example, Figure 9 This diagram serves as a conceptual illustration of the target color coordinates and the range of target color coordinates defined by the target subdivision hue and the preset color tolerance. It should be noted that this diagram is not a schematic diagram of the color coordinate range division for subdivision hues.

[0217] In these embodiments, the method can efficiently and accurately match the color of light at the subdivided hue level, effectively avoid misjudgment caused by slight color differences or measurement errors, and greatly improve the accuracy and reliability of light color recognition.

[0218] To more accurately determine the saturation level of the light color, in some embodiments, the saturation level most similar to the light color is determined in the saturation ring corresponding to the subdivision color, including:

[0219] Based on the saturation ring corresponding to the subdivided colors, the saturation gradation points are determined in the chromaticity diagram.

[0220] Determine the color coordinates of the light source;

[0221] Obtain the nearest target saturation level point with the light color coordinates;

[0222] The saturation level corresponding to the target saturation grading point is determined as the saturation level of the light color.

[0223] In some embodiments, saturation grading points refer to specific coordinate positions on the saturation ring corresponding to different saturation levels. Each point represents a specific saturation level, and the saturation difference between adjacent points is fixed. In the chromaticity diagram, these points are distributed in specific regions corresponding to subdivided hues, arranged along the saturation direction. By determining these grading points, continuous saturation changes can be discretized into specific levels, facilitating accurate description and classification of the saturation of light colors.

[0224] In some embodiments, the target saturation level point refers to the point among the many level points in the saturation ring that is closest to the light color coordinates. When determining the saturation level of a light color, the light color coordinates are first obtained, then the distance between these coordinates and each saturation level point is calculated. The point with the smallest distance is the target saturation level point. Its corresponding saturation level is the saturation level most similar to the light color.

[0225] For example, based on the saturation ring, a series of saturation grading points such as (0.2, 0.3) and (0.22, 0.32) are located on the chromaticity diagram; the color coordinates of the light source are measured using professional instruments as (0.21, 0.31); then, by calculating the distance between each grading point and the color coordinates of the light source, it is found that the saturation grading point (0.22, 0.32) is closest to the color coordinates of the light source, thus obtaining the target saturation grading point; finally, the saturation level corresponding to the target saturation grading point is determined to be level 7, that is, the saturation level of the light color is level 7.

[0226] For example, Figure 10 This shows the effect of saturation gradation points on a chromaticity diagram. Among them, Figure 10 The saturation level points within the black box correspond to the saturation levels.

[0227] For example, this method performs color segmentation on the CIE 1931 chromaticity diagram, taking color tolerance into account. The segmentation result contains 497 colors, and each color has its own color coordinates. From this, we can understand... Figure 10 There are 497 colors (including white dots) within the black border, which correspond to all the colors in the digital color library of lights.

[0228] For example, Figure 10 When a 7-color gamut is selected, this method can determine 413 colors (including the central white point) under 40 subdivisions of the hue, along with their corresponding color coordinates. Similarly, when selecting 6-color, 5-color, or 4-color gamuts, the corresponding number of colors and their corresponding color coordinates can be determined.

[0229] For example, Figure 10 The image shows 10 preset basic hues, and 40 sub-hues formed by dividing each hue into four equal parts. Since each sub-hue has corresponding multiple saturations, therefore... Figure 10 It also shows the different color coordinates corresponding to different saturations within each subdivided hue. Therefore, it can be concluded that... Figure 10Specifically, it shows 497 color coordinate points (including the central white point) divided on the CIE 1931 colorimetric diagram. These color coordinate points correspond to different basic hues, subdivision hues, and saturation levels.

[0230] In some embodiments, because the light source cannot cover all colors on the CIE 1931 chromaticity diagram, therefore, like... Figure 10 As shown, when the light source faces a 7-color gamut, it has 413 selectable coordinate points (including the center white point). That is, color coordinates outside this color gamut cannot be realized.

[0231] For example, see Figure 11 , Figure 11 This illustrates the relationship between the width of the color gamut and the number of corresponding color coordinate points. Among them, Figure 11 The difference between the 7-color and 3-color gamuts is shown, revealing that some color coordinates can be achieved by a 7-color light source but not by a 3-color light source. Therefore, Figure 11 Note: As the color gamut narrows (e.g., from a 7-color gamut to a 6-color gamut, 5-color gamut, 4-color gamut, or 3-color gamut), the number of colors that the light source can display also decreases.

[0232] In these embodiments, the method can efficiently and accurately identify the color of light at the saturation level, providing a reliable basis for scenarios such as light color design and quality inspection, ensuring that the color of light meets the expected standard in terms of saturation performance, and greatly improving the professionalism and accuracy of color management.

[0233] To more effectively encode light colors, in some embodiments, color codes are generated based on a basic hue, subdivided hue, and saturation levels, including:

[0234] The color code for light color is generated based on the letter identifier of the basic hue, the numerical identifier of the subdivided hue, and the numerical identifier of the saturation level.

[0235] In some embodiments, the letter designation for the basic hue can be red (R), yellow (Y), etc.

[0236] In some embodiments, the numerical identifier for the subdivided hue can be 25, 50, 75, etc.

[0237] In some embodiments, the numerical identifier for the saturation level can be 02, 04, 06, 08, etc.

[0238] For example, the color code can be B50 10, P50 10, etc.

[0239] In these embodiments, light color codes are generated based on identifiers of basic hue, subdivided hue, and saturation levels. This enables accurate digital description of colors, is concise and efficient, and provides comprehensive information. It facilitates unified management and communication across all aspects of the industry, reduces errors, and improves color matching and application efficiency.

[0240] Example 3

[0241] like Figure 12 As shown, some embodiments of this application provide a light output control method, which includes:

[0242] S401. Obtain the color code of the light color to be output; the color code is obtained by the light color coding method based on the light digital color library in any of the embodiments in Example 2.

[0243] S402, Control the output of lights corresponding to color codes based on the lighting control console.

[0244] In some embodiments, a lighting control console is a professional device used for centralized control and management of various lighting systems such as stage lighting, architectural lighting, and landscape lighting, playing a key role in multiple fields such as performing arts, film and television, architecture, and exhibitions.

[0245] In these embodiments, the method achieves a seamless transition from digital encoding to actual output of light colors. This approach not only improves the accuracy and consistency of light color output, ensuring a high degree of uniformity in light colors across different devices and scenarios, but also significantly enhances lighting control efficiency. Operators can quickly access color codes from the digital color library to complete lighting settings, providing an efficient, reliable, and standardized solution for various lighting application scenarios.

[0246] To accurately and effectively control the output of lights, in some embodiments, the output lights corresponding to color codes are controlled based on a light control console, including:

[0247] Identify the corresponding subdivisions of hue and saturation levels in color coding;

[0248] The first control value of the first channel in the lighting control console is determined based on the subdivided hue, and the second control value of the second channel in the lighting control console is determined based on the saturation level.

[0249] Based on the first and second control variables, the lighting control console outputs the light corresponding to the color code.

[0250] In some embodiments, the lighting control console determines the control values ​​of two different channels (the first channel and the second channel) based on the identified subdivided hue and saturation levels, and then outputs the light corresponding to the color code.

[0251] In some embodiments, the first channel refers to a control channel in a lighting control console, the control amount of which is determined by the subdivision hue in color coding. By adjusting the control amount of the first channel, the hue of the light output can be changed to conform to the color characteristics corresponding to the subdivision hue.

[0252] In some embodiments, the second channel refers to another control channel in the lighting control panel, the control amount of which is determined by the saturation level in the color coding. By adjusting the control amount of the second channel, the vividness of the light output can be changed to achieve a color effect that matches the saturation level.

[0253] In some embodiments, the first control variable is determined based on the subdivision hue in the color coding and is used to control the output parameters of the first channel of the lighting control console, thereby adjusting the hue of the light output. Different subdivision hues correspond to different first control variables to achieve various hues of light output.

[0254] In some embodiments, the second control variable is determined based on the saturation level in the color coding and is used to control the output parameters of the second channel of the lighting control console, thereby changing the vibrancy of the light output. Different saturation levels correspond to different second control variables, enabling the light to present different effects from dull to vibrant.

[0255] For example, the following diagram shows the correspondence between the first and second control quantities and the light control console push rod.

[0256]

[0257]

[0258] Note: The coordinates for the saturation of each color are different, with a minimum of only 6 coordinates and a maximum of 18 coordinates.

[0259] In these embodiments, the method can achieve precise matching and flexible control of light color from encoding to actual output, thereby effectively improving the accuracy of light color reproduction and the convenience of control, and thus meeting the needs of diverse lighting scenarios for highly customized and precise color output.

[0260] To facilitate manual control by staff, in some embodiments, based on a first control variable and a second control variable, the lighting control console is controlled to output lights corresponding to color codes, including:

[0261] Display the first and second control values ​​on the target display;

[0262] The testing personnel operate the lighting control console based on the first and second control variables to make the lighting control console output lights corresponding to the color codes.

[0263] In some embodiments, when an operator controls the lighting control console, they can adjust the lever on the lighting control console based on a first control quantity and a second control quantity, thereby controlling the lighting output.

[0264] In these embodiments, the method can improve the visualization and interactivity of lighting control, thereby not only facilitating real-time monitoring and adjustment of lighting parameters by staff and ensuring that the lighting output accurately meets color coding requirements, but also reducing the difficulty of operation and error rate, and improving the efficiency and quality of lighting control work.

[0268] S502. Output the optimized color library image in the target software so that the user's operation on the optimized color library image is reflected in the target software.

[0269] In some embodiments, display optimization refers to improvements and adjustments to the display of a digital color library for lighting, with the aim of presenting the color information in the library to the user in a clearer and more accurate manner. For example, optimizing the display accuracy of colors to avoid color deviations during display; adjusting the arrangement of colors to better suit the user's visual habits, making it easier for the user to find and compare different colors.

[0270] In some embodiments, UI stands for User Interface. UI setup is the process of designing and configuring the user interface for a digital color library of lights. This includes determining the layout of the interface, the position and style of elements (such as buttons, menus, icons, etc.), and interaction methods. Good UI setup can improve the ease and comfort of user operation, enabling users to interact with the color library more easily.

[0271] In some embodiments, an optimized color library diagram refers to the graphical representation of a digital color library after display optimization and UI settings.

Optimized color library diagrams typically retain the core data information of the color library while enhancing the user experience through optimized display and UI design.

[0272] In some embodiments, target software refers to a specific application where the user needs to use a digital color library for lighting. This software might be a lighting design software or stage control software, in which the user needs to use the digital color library to select and apply appropriate lighting colors. Outputting an optimized color library image to the target software allows the color library to be integrated with the functionality of the target software, enabling the user to directly use the colors from the color library within the target software's workflow.

[0273] In some embodiments, user operations on the optimized color library image refer to various operations performed by the user on the optimized color library image within the target software.

[0274] In these embodiments, the method enables users to browse, select, and apply light colors more conveniently and intuitively within the target software environment. It also enhances the integration of the digital light color library with the target software, expands the application scenarios and functional implementation methods of the color library, and improves the efficiency and quality of lighting design, control, and other tasks.

[0275] To better achieve matching optimization, in some embodiments, the display of the digital color library for lighting is optimized and the UI settings are adjusted to obtain an optimized color library image, including:

[0276] Adjustments were made to the color boundary clarity of the digital color library for lighting, annotations were added to the encoded letters and numbers, the human-computer interaction interface was optimized, and the operation logic was set.

[0277] For example, Figure 14 An example diagram of an optimized color library image is shown.

[0278] In these embodiments, the method can make the light color more accurate and unambiguous in the color library by adjusting the clarity of the color boundary. Adding coded letters and numbers to the annotations facilitates users' quick understanding of the color code meaning. Optimizing the human-computer interface improves operational convenience and visual comfort. The setting of the operation logic makes the operation more user-friendly and reduces the learning cost. In summary, this method improves the overall usability, ease of use, and professionalism of the digital light color library, helping users efficiently complete lighting-related tasks.
