Display Content White Balancing Under Varying Ambient Color Temperatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer electronic devices face perceptual color tone distortion due to varying ambient color temperatures, which deviate from the intended creative intent of the content, especially when viewed in different lighting conditions.
Innovation Solution
A method and system that adaptively corrects input content based on ambient contextual data, applying automatic white balancing to preserve the creative intent by compensating for color tone distortions caused by varying ambient lighting conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If content is displayed without correction in varying ambient lighting conditions, then device complexity is reduced, but perceptual color tone distortion occurs and creative intent is compromised
Solution Approach 1:
The system captures ambient lighting conditions before content display and pre-calculates correction parameters. Sensors measure ambient color temperature and illuminance in advance, allowing the processing system to prepare correction matrices before content is rendered, thus maintaining color accuracy without adding complex real-time processing requirements.
Solution Approach 2:
The patent introduces an intermediary processing layer between content source and display that applies color correction transformations. This intermediary system uses measured ambient conditions to generate correction matrices that mediate between the original content and the display output, preserving creative intent without requiring changes to the display hardware itself.
2Manufacturing precision
If automatic white balancing is applied to correct color tone, then color tone accuracy is improved, but processing time and computational resources increase
Solution Approach 1:
The system applies partial correction by focusing computational resources on correcting only the dominant ambient lighting effects rather than performing complete color space transformations. By measuring ambient color temperature and illuminance separately, the system applies targeted corrections for each factor, reducing overall processing time while maintaining color tone accuracy.
Solution Approach 2:
The patent transforms the color correction problem from a complex multi-dimensional optimization into a parameter-driven approach. By measuring ambient conditions as specific parameters (color temperature, illuminance) and using these to select from pre-computed correction matrices, the system reduces computational complexity and processing time while maintaining correction accuracy.
3Manufacturing precision
If content is corrected for one ambient condition, then color tone accuracy for that condition is improved, but adaptability to other ambient conditions deteriorates
Solution Approach 1:
The system dynamically adapts correction parameters based on measured ambient conditions rather than using fixed correction matrices. Sensors continuously monitor ambient color temperature and illuminance, and the processing system adjusts correction matrices in real-time to match current viewing conditions, maintaining color tone consistency across varying environments.
Solution Approach 2:
The patent creates a universal correction system that handles multiple ambient conditions through a single adaptive framework. Rather than creating separate correction pipelines for different lighting scenarios, the system uses a unified approach that measures ambient parameters and selects/appplies appropriate correction matrices from a comprehensive set, enabling adaptability to any ambient condition while maintaining color accuracy.

AI summary
One embodiment provides a method comprising receiving an input content, and receiving ambient contextual data indicative of one or more ambient lighting conditions of an environment including a display device. The input content has corresponding metadata that at least partially represents a creative intent indicative of how the input content is intended to be viewed. The method further comprises adaptively correcting the input content based on the ambient contextual data to preserve the creative intent, and providing the corrected input content to the display device for presentation. The adaptively correcting comprises applying automatic white balancing to the input content to correct color tone of the input content.
