Ambient Light Sensor System for Video Color Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ambient light in local viewing environments can distort viewers' perceptions of video content colors and contrasts, particularly due to dim lighting causing night vision effects and color suffusion, which existing technologies fail to accurately correct.
Innovation Solution
A system that uses ambient light sensors and smart home technologies to adjust lighting conditions, including artificial lighting and window blinds, to maintain optimal ambient light levels and color balance, ensuring viewers perceive colors as intended by content providers, utilizing cameras, smart glasses, and networked interfaces to gather and respond to ambient light data in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ambient light sensing is used to adjust display brightness, then ease of operation is improved, but manufacturing precision deteriorates because the system cannot accurately maintain intended color and brightness levels
Solution Approach 1:
The system continuously monitors ambient light conditions and automatically adjusts display parameters, creating a closed-loop feedback mechanism that adapts to changing viewing environments while maintaining color accuracy through sophisticated processing algorithms
Solution Approach 2:
The system changes multiple display parameters simultaneously (brightness, contrast, color temperature, white balance) based on ambient light measurements, transforming the approach from simple brightness adjustment to comprehensive visual parameter optimization
2Object-affected harmful factors
If display brightness is adjusted based on ambient light, then object-affected harmful factors are reduced, but loss of information increases because the displayed content deviates from intended colors
Solution Approach 1:
The system adjusts multiple visual parameters (brightness, contrast, color temperature, white balance) in coordination rather than simply dimming the display, thereby reducing eye strain while preserving the integrity of the displayed content's color and brightness information
3Device complexity
If simple ambient light sensing is used, then device complexity is reduced, but measurement precision deteriorates because the system cannot accurately determine optimal viewing conditions
Solution Approach 1:
The system uses a single ambient light sensor to perform multiple measurement functions (brightness level, color temperature, white balance determination) rather than requiring separate sensors for each parameter, thereby maintaining device simplicity while achieving comprehensive environmental characterization

AI summary
Methods and systems to evaluate the ambient light in a local viewing environment where video content is being displayed, and to make adjustments to the ambient light, video display device, and/or video content to cause the perception of the color and brightness of the video content to the viewer to be true to what the video content producer intended the viewer to perceive.
