Lighting Control Device Automatic Color Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lighting systems require manual selection of colors from images, which may not appear pleasant and often necessitate full-color lighting systems, not commonly installed in homes, making it difficult for users to reproduce desired colors accurately.
Innovation Solution
A lighting control device integrated into a mobile terminal that automatically selects and adjusts colors for illumination based on an image, using a candidate color selector, adjuster, and controller to determine reproducible colors, allowing for pleasant illumination spaces without the need for full-color systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual color selection from picture is implemented, then color reproduction is achieved, but the selected color may not appear pleasant to human eyes and requires full-color lighting systems
Solution Approach 1:
The system performs automatic color selection and adjustment without requiring manual operator intervention. The controller automatically selects candidate colors from the picture, adjusts them based on lighting device capabilities and human visual comfort criteria, and determines the final reproduction color, enabling the system to serve itself in the color selection process
Solution Approach 2:
The manual mechanical process of color selection and adjustment is replaced by an automated computational system. The controller uses image processing algorithms and color science calculations to automatically determine optimal colors, substituting the manual operator's visual assessment and manual adjustment with automated digital processing
2Adaptability or versatility
If full-color lighting system is used, then color reproduction capability is improved, but device complexity and cost increase
Solution Approach 1:
The system changes the approach from hardware capability (full-color lighting devices) to software processing (automatic color selection and adjustment algorithms). By modifying the control parameters and using intelligent color selection based on picture analysis and human visual characteristics, the system achieves good color reproduction with simpler, more commonly installed lighting devices
Solution Approach 2:
The lighting control device is designed to work with various types of lighting systems, not just full-color systems. The automatic color selection and adjustment functionality makes the system universal, allowing it to achieve good color reproduction with different lighting device configurations including commonly installed non-full-color systems
3Ease of operation
If automatic color selection is implemented, then ease of operation is improved, but processing complexity increases
Solution Approach 1:
The complex color selection and adjustment processing is extracted from the mobile terminal application and implemented in the lighting control device controller. This extraction allows the mobile terminal to provide a simple user interface while the controller handles the computationally intensive image processing, color analysis, and automatic adjustment algorithms

AI summary
A lighting control device includes: a candidate color selector; a candidate color adjuster; and a color controller. The candidate color selector selects, in accordance with the indication obtained by the indication obtainer, a plurality of candidate colors to be used for color control of lighting devices, from an image obtained by an image obtainer. The candidate color adjuster makes automatic-mode adjustment which is processing for determining colors reproducible by the lighting devices, in accordance with predetermined indexes and based on the plurality of candidate colors selected by the candidate color selector. The color controller causes the lighting devices to each emit illumination light having the color determined by the candidate color adjuster, by controlling the lighting devices.
