Endoscope Illumination Switching for Target-Aware Image Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope systems fail to provide highly accurate analysis results due to the inability to switch between different types of illumination light based on the observation situation, leading to inappropriate illumination characteristics for various analysis types.
Innovation Solution
An endoscope system and control program that can switch between multiple types of illumination light with distinct characteristics, allowing the display to adapt analysis results based on the size of the target area within the subject, using a light source capable of emitting different types of light and a processor to determine the appropriate illumination based on the observation situation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple operation modes are provided in the endoscope system, then versatility and adaptability are improved, but device complexity increases
Solution Approach 1:
The endoscope system is designed to perform multiple functions through a unified architecture. The image processing device can operate in different modes (real-time display, post-processing, analysis) without requiring separate dedicated systems for each function. This multi-functionality approach allows the system to adapt to various surgical needs while maintaining a single integrated device structure.
Solution Approach 2:
The system employs dynamic switching between different operation modes based on surgical requirements. The image processing device can dynamically adjust its processing algorithms, display parameters, and data analysis functions during procedures. This dynamic adaptability allows the system to transition between modes seamlessly, providing versatility without requiring physically separate systems for each mode.
2Measurement precision
If real-time display and post-processing are performed, then diagnostic accuracy is improved, but processing time increases
Solution Approach 1:
The system performs preliminary real-time processing and preliminary diagnosis during the surgical procedure itself. Image processing algorithms continuously analyze captured images in real-time, providing immediate diagnostic information. This preliminary action ensures that diagnostic accuracy is maintained while minimizing delays, as the processing is already underway before formal post-processing is required.
Solution Approach 2:
The image processing operates continuously throughout the surgical procedure rather than being performed as a separate batch process. The system maintains continuous real-time display while simultaneously preparing data for post-processing analysis. This continuity ensures that diagnostic accuracy is achieved without significant time loss, as the processing action never stops but rather transitions smoothly between real-time and post-processing phases.
