Color Reproduction Service Using Controlled Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current color reproduction systems lack the ability to accurately and efficiently create custom colors for diverse populations, particularly in applications like liquid makeup foundations, as they often rely on inadequate lighting setups and image capturing settings, leading to inconsistent color matching.
Innovation Solution
A system that isolates ambient light and uses consistently replicable lighting setups with image capturing devices to determine the color of a subject, then calculates a mixture of base materials to match that color, utilizing multiple photographs and light meter data to ensure precision across different image capturing settings and lighting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If inconsistent lighting setups and image capturing settings are used, then device complexity is reduced, but color measurement precision deteriorates
Solution Approach 1:
The patent applies parameter changes by systematically varying lighting parameters (color temperature, intensity, angle) and image capturing parameters (exposure, white balance, color space) to create a comprehensive color profile for each base material. Multiple photographs are taken under different controlled conditions, and the results are integrated to determine accurate color values that are independent of specific lighting or capturing settings.
2Measurement precision
If multiple photographs with different settings are used, then color measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-characterizing base materials under multiple lighting and capturing conditions before actual color matching is needed. The system creates a comprehensive color profile database in advance, allowing rapid color determination during actual use without requiring multiple photographs to be taken at the moment of color matching.
Solution Approach 2:
The system uses feedback by comparing captured images against pre-established color profiles and iteratively adjusting the determined color values. The color determination process incorporates feedback from multiple image analyses to converge on accurate color values, reducing the need for repeated measurements.
3Reliability
If ambient light is not isolated, then ease of operation is improved, but reliability of color measurement deteriorates
Solution Approach 1:
The patent introduces an intermediary controlled environment (light isolation structure) between the ambient environment and the subject being measured. This intermediary structure blocks ambient light while allowing controlled illumination to reach the subject, ensuring that only known light sources contribute to the color measurement without complicating the overall operational procedure.
4Measurement precision
If spectroscopic measurements are used, then color measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex spectroscopic measurement systems with a simpler digital imaging system. Instead of using spectrometers or spectroscopic equipment, the invention uses standard digital cameras or image sensors combined with controlled lighting to capture color information. The system processes multiple images under different lighting conditions to achieve color accuracy comparable to or exceeding traditional spectroscopic methods, but with significantly reduced device complexity and cost.
