Time-Division Control for Multi-Source Imaging Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a scenario where multiple imaging devices are used as monitoring cameras, the interference of auxiliary light from multiple light sources complicates image capture, leading to issues like flicker and overexposure due to unsynchronized light emission.
Innovation Solution
A control system that synchronizes the light emission of auxiliary light sources in a time-division manner, ensuring each imaging device captures images only when its associated light source is emitting, thereby preventing interference and maintaining optimal exposure control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If multiple light sources emit auxiliary light simultaneously, then the imaging environment is enhanced, but light interference occurs causing flicker and overexposure
Solution Approach 1:
The patent implements time-division multiplexed control where multiple light sources emit auxiliary light in alternating periodic intervals rather than simultaneously. Each light source is controlled to emit light during specific time slots, creating a periodic emission pattern that eliminates overlapping light interference while maintaining continuous imaging capability across multiple devices.
2Adaptability or versatility
If multiple imaging devices operate independently, then device versatility is maintained, but synchronization control becomes difficult
Solution Approach 1:
The patent segments the operation of multiple imaging devices into distinct time slots, where each device operates independently during its assigned interval. This temporal segmentation allows each device to maintain its independent functionality and imaging parameters while the overall system achieves synchronization through the structured time-division framework, reducing the complexity of real-time coordination.
