Infrared Camera Interference Mitigation via Dynamic Parameter Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infrared cameras and nearby devices experience performance degradation due to environmental and interference conditions caused by camera placement, which existing technologies fail to effectively recognize and mitigate.
Innovation Solution
An entertainment computing device analyzes infrared images from the camera to recognize interference conditions and outputs instructions to adjust camera placement or settings to mitigate these conditions, using techniques such as adjusting infrared laser power, frame rate, or providing user notifications to move objects, thereby reducing interference and enhancing infrared performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the camera emits infrared light to capture images, then the camera can perform its imaging function, but it causes interference to proximate infrared devices and degrades their performance
Solution Approach 1:
The system continuously monitors the environment for infrared devices and detects interference conditions. When interference is detected, the camera adjusts its infrared emission parameters (power, frame rate) based on this feedback to mitigate the harmful effect while maintaining imaging functionality.
Solution Approach 2:
The camera's infrared emission parameters are made dynamic and adjustable rather than fixed. The system can change infrared laser power and frame rate in real-time based on the presence and sensitivity of nearby infrared devices, allowing optimization of both imaging performance and interference reduction.
2Measurement precision
If the camera operates at high infrared power to improve image quality, then imaging performance is enhanced, but interference with proximate infrared devices increases
Solution Approach 1:
The system changes the parameters of infrared emission (power level, frame rate) based on environmental conditions. When infrared devices are detected in proximity, the camera reduces its infrared power or frame rate to minimize interference while attempting to maintain acceptable image quality through alternative optimization.
Solution Approach 2:
The camera applies partial action by reducing infrared power or frame rate only when and where interference is detected, rather than operating at full power continuously. This allows the camera to maintain high performance when no interference is present while reducing harmful effects when devices are nearby.
3Ease of manufacture
If the camera placement is fixed to simplify installation, then ease of installation is improved, but interference conditions cannot be optimized
Solution Approach 1:
The camera system performs self-service by automatically detecting interference conditions and adjusting its own operating parameters (infrared power, frame rate) without requiring manual repositioning or complex installation procedures. This maintains installation simplicity while dynamically optimizing performance.
Solution Approach 2:
The system performs preliminary detection of the environment during or after installation to identify the presence of infrared devices. Based on this preliminary action, the camera pre-adjusts its parameters to prevent interference before it becomes a problem, eliminating the need for complex installation planning.
