Ambient Light Detection for Display Image Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The perceived quality of visual images displayed on visual displays is affected by ambient light, leading to poor image quality due to mismatches between ambient light characteristics and displayed image features, especially in varying lighting conditions such as those found in automotive or aircraft applications.
Innovation Solution
A computing device configured to couple with a display, featuring an ambient detection module to detect characteristics of ambient light and a displayed image optimization module to optimize image features based on these characteristics, viewer preferences, and emotional states, while also considering features of the display frame image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the displayed image features are kept fixed, then the device complexity is reduced, but the perceived image quality deteriorates under varying ambient light conditions
Solution Approach 1:
The patent implements dynamic adjustment of displayed image features (such as brightness, contrast, color temperature) based on real-time ambient light detection. The system transitions from static fixed features to dynamically adaptable features that automatically respond to changing ambient conditions, resolving the contradiction between maintaining simple device architecture and ensuring consistent image quality across varying environments.
Solution Approach 2:
The system changes key parameters of the displayed image (illuminance, spectral power distribution, contrast) in response to detected ambient light characteristics. By adjusting these parameters dynamically rather than keeping them fixed, the system maintains reliable image quality without requiring complex manual intervention or overly sophisticated hardware modifications.
2Reliability
If ambient light detection and image optimization modules are added, then the perceived image quality improves, but the device complexity increases
Solution Approach 1:
The patent integrates multiple functions into unified modules: the ambient detection module serves both to characterize ambient light conditions and to trigger appropriate optimization responses, while the image optimization module handles multiple adjustment parameters (brightness, contrast, color temperature) through a single coordinated system. This multi-functionality approach improves image quality without proportionally increasing overall device complexity.
Solution Approach 2:
The system implements self-service through automatic ambient light detection and autonomous image parameter optimization. The displayed image optimization module automatically adjusts image features based on ambient conditions without requiring manual user intervention or complex external control systems, thereby improving perceived image quality while keeping the control architecture relatively simple.
3Adaptability or versatility
If the display adapts to ambient light conditions, then the adaptability improves, but the energy consumption increases due to continuous detection and adjustment
Solution Approach 1:
The system employs periodic rather than continuous ambient light detection and image adjustment. By detecting ambient light conditions at regular intervals and adjusting display parameters accordingly, the system maintains high adaptability to changing environments while significantly reducing energy consumption compared to continuous real-time monitoring and adjustment operations.
