Lighting Script Generation via Video Color Palette Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scripting applications for lighting systems require significant time and effort for users to generate lighting scripts, even for short video content, as they need to manually specify illumination effects, which can be overwhelming and time-consuming.
Innovation Solution
A method that processes frame image data to automatically determine color palettes from video content, generating a default sequence of illumination effects that users can modify, and provides a color selector for manual adjustments, simplifying the scripting process by pre-segmenting video content and accounting for lighting system capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually specify illumination effects in scripting applications, then customization and control over lighting scenes are improved, but the time and effort required to generate lighting scripts increases significantly
Solution Approach 1:
The system performs preliminary analysis of video content to automatically generate color palettes and default lighting sequences before user interaction. This preliminary action provides a ready-to-use foundation that users can then modify, eliminating the need to create lighting scripts from scratch while maintaining full customization capability.
Solution Approach 2:
The system enables self-service by automatically extracting color information from video content and generating corresponding illumination effects without requiring manual user input. The lighting system serves itself by analyzing the video data and creating appropriate lighting sequences, which users can then review and adjust if needed.
2Adaptability or versatility
If scripting applications provide significant freedom in lighting scene generation, then user control and customization are improved, but the complexity of the scripting process increases
Solution Approach 1:
The system segments the lighting script generation process into distinct components: automatic color palette extraction from video content, default sequence generation, and user customization options. This segmentation allows users to engage with only the portions they want to control while accepting automated portions, reducing overall complexity while maintaining freedom.
Solution Approach 2:
The system applies different levels of automation to different aspects of lighting scene generation. Color extraction and basic sequence generation are fully automated with high quality, while user customization options remain available for those who want to modify specific parameters. This local quality approach ensures each part of the system operates at the appropriate level of complexity.
3Productivity
If automatic color palette extraction is implemented, then the speed of generating lighting scripts is improved, but the precision of matching user-specific illumination effects may be reduced
Solution Approach 1:
The system provides dynamic adjustment capabilities that allow users to modify automatically generated lighting sequences in real-time. The transition from static automatic generation to dynamic user-adjustable parameters enables the system to adapt to precise user requirements while maintaining the initial speed advantage of automatic generation.
Solution Approach 2:
The system incorporates feedback mechanisms that allow users to review and adjust the automatically generated color palettes and lighting sequences. This feedback loop ensures that the final output meets user-specific precision requirements while retaining the efficiency benefits of automatic extraction.

AI summary
A lighting script—for use by a lighting controller to control at least one luminaire to render illumination effects, as the video content is outputted in a space illuminated by the at least one luminaire, synchronously with the outputting of the video content—is generated as follows. Frame image data of the video content is processed to determine at least one color palette of the frame image data. A sequence of illumination effects—to be rendered during the outputting of the video content and which is modifiable by a user—is displayed to the user. The displayed sequence conveys at least one illumination color derived from the determined color palette to be rendered in at least one of the illumination effects. The generated lighting script is for rendering the modified sequence of illumination effects.
