Adaptive Display Luminance Control for Photosensitive Seizure Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses fail to adequately prevent adverse physical reactions such as photosensitive seizures due to variations in luminance or saturation, as they do not account for external factors like surrounding brightness and user distance, leading to either ineffective prevention or undesirable image quality.
Innovation Solution
A display apparatus that acquires external factors using cameras and sensors to adjust the variation range of luminance and saturation based on illuminance and viewing distance, and optionally adjusts connected lighting to optimize video display conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the display apparatus restricts the variation range of luminance or saturation to prevent photosensitive seizures, then the safety against adverse physical reactions is improved, but the image quality and viewing comfort deteriorate
Solution Approach 1:
The display apparatus dynamically adjusts the variation range of luminance or saturation based on real-time acquisition of external factors (surrounding brightness, user distance) and video characteristics. The restriction level is not fixed but adapts to changing conditions, allowing the system to prevent photosensitive seizures in high-risk situations while maintaining natural image quality in safe conditions.
Solution Approach 2:
The system changes the parameter of variation range restriction based on multiple factors including external lighting conditions, viewing distance, and video content characteristics. By adjusting this parameter dynamically rather than applying a constant restriction, the system optimizes between safety and viewing comfort.
2Object-affected harmful factors
If the display apparatus applies strong restriction on luminance or saturation variation, then the prevention of adverse physical reactions is improved, but the image processing becomes excessive and unnatural
Solution Approach 1:
The system applies partial restriction rather than complete suppression of luminance or saturation variation. By adjusting the degree of restriction based on the actual risk level from external factors and video characteristics, the system prevents adverse reactions without over-processing the image data.
Solution Approach 2:
The display apparatus continuously acquires external factors and video information, processes this feedback to determine the appropriate restriction level, and adjusts the processing accordingly. This feedback mechanism ensures that restriction is applied only when and where necessary, avoiding excessive processing.
3Device complexity
If the display apparatus uses fixed restriction levels for luminance or saturation, then the control complexity is reduced, but the adaptability to different viewing conditions deteriorates
Solution Approach 1:
The system transitions from static to dynamic control by continuously acquiring external factors (surrounding brightness, user distance) and adjusting the restriction level in real-time. This dynamic approach increases adaptability to different viewing conditions while managing complexity through automated sensor-based control.
Solution Approach 2:
The display apparatus autonomously acquires external factor information and automatically determines appropriate restriction levels without requiring manual user input or complex control interfaces. The system serves itself by using sensors and built-in processing to adapt to changing conditions.
