Endoscope Adapter Automating White Balance Parameter Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscope systems require frequent adjustments, such as white balance adjustments, each time an endoscope is used, which can be cumbersome and complicated, especially when dealing with multiple types of endoscopes and processors.
Innovation Solution
An adapter and processor system that stores and retrieves adjustment parameters, including white balance settings, using nonvolatile memory and identification information to automate the adjustment process, allowing for seamless connection and operation of endoscopes without manual adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual white balance adjustment is performed each time an endoscope is used, then image quality can be optimized, but operation time and complexity increase significantly
Solution Approach 1:
The system performs white balance adjustment in advance and stores the adjustment parameters in nonvolatile memory of the adapter. When the endoscope is connected again, the pre-stored parameters are automatically retrieved and applied, eliminating the need for repeated manual adjustments while maintaining image quality
Solution Approach 2:
The adjustment parameters obtained through manual white balance adjustment are copied and stored in the adapter's nonvolatile memory. This creates a reusable set of parameters that can be automatically applied to future connections, replacing the need to perform the adjustment process again
2Adaptability or versatility
If multiple types of endoscopes are connected to the processor, then versatility is improved, but the complexity of managing different adjustment parameters increases
Solution Approach 1:
The adapter serves as an intermediary device between the endoscope and processor. It contains nonvolatile memory that stores adjustment parameters specific to each endoscope type, automatically retrieving and providing the correct parameters when an endoscope is connected, thereby simplifying parameter management across multiple endoscope types
Solution Approach 2:
The adjustment parameters are extracted from the processor and stored in the adapter's nonvolatile memory. This separates the parameter storage function from the processor, allowing each endoscope type's parameters to be independently managed in the adapter without complicating the processor's operation
