Endoscope Processor Color Adaptation for Xenon Halogen Mismatch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic endoscopes designed for xenon lamps struggle to provide faithful color reproducibility when used with halogen lamps, leading to inefficient utilization of medical resources due to lack of appropriate color adjustment data for halogen light sources.
Innovation Solution
A processor for electronic endoscopes is designed to determine if the stored color adjustment data is compatible with the light source, acquire and apply color conversion data to adjust the image signal, ensuring accurate color representation regardless of the light source type, and optionally store and transmit color adjustment data to the videoscope for further processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If color adjustment data adapted to xenon lamp is used in videoscope connected to processor with halogen lamp, then device complexity is reduced and ease of operation is improved, but color reproducibility deteriorates
Solution Approach 1:
The patent introduces color conversion data as an intermediary element between the videoscope's color adjustment data and the final image output. When a videoscope with xenon-adapted color adjustment data is connected to a processor with halogen lamp, the color conversion data acts as a mediator to transform the mismatched color signals, enabling faithful color reproduction without requiring the videoscope to have halogen-specific adjustment data built in.
Solution Approach 2:
The patent changes the parameter of color adjustment by storing multiple sets of color conversion data corresponding to different light sources (xenon, halogen, LED) and selectively applying the appropriate conversion data based on the actual light source being used. This allows the system to adapt color parameters dynamically without modifying the videoscope's internal color adjustment data.
2Manufacturing precision
If videoscope is designed for specific light source type, then manufacturing precision for that light source is improved, but adaptability to different light sources deteriorates
Solution Approach 1:
The patent makes the processor universal by enabling it to work with videoscopes designed for different light source types (xenon, halogen, LED). The processor stores multiple sets of color conversion data and can adapt to whichever light source is actually used, allowing a single videoscope design to be paired with different processor/light source combinations while maintaining color accuracy.
Solution Approach 2:
The color conversion data serves as an intermediary that bridges the gap between videoscopes designed for specific light sources and processors using different light sources. This intermediary layer of color conversion allows the system to maintain high color reproducibility while achieving versatility across different light source configurations.
3Device complexity
If color adjustment data is stored in videoscope, then device complexity is reduced, but loss of information occurs when light source type mismatches
Solution Approach 1:
The patent introduces color conversion data stored in the processor as an intermediary to prevent loss of color information. When the light source type mismatches the videoscope's built-in color adjustment data, this intermediary conversion data compensates for the mismatch, ensuring that no color information is lost despite the incompatibility between the videoscope's predetermined adjustment data and the actual light source characteristics.
