Solution Overview
Problem
Current imaging systems struggle to capture clear in-vivo images of internal body structures using multi-spectral imaging, particularly due to low luminance in green and blue wavelength components, which results in poor contrast and unclear blood vessel images.
Innovation Solution
An imaging processor and medical system that includes an amplifier to increase luminance in green and blue image data based on red image data, allowing for enhanced contrast adjustment and clearer special light images by amplifying green and blue data using red data as a reference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-spectral imaging is used to capture in-vivo images, then image data in multiple wavelength components can be obtained, but luminance in green and blue wavelength components is low resulting in poor contrast
Solution Approach 1:
The patent applies parameter changes by adjusting the luminance parameter of green and blue image data through amplification based on red image data. This resolves the contradiction by changing the luminance parameter to achieve sufficient brightness while maintaining multi-spectral imaging capability
Solution Approach 2:
The patent uses red image data as an intermediary to amplify green and blue image data. The red data serves as a mediator that provides the reference luminance information needed to enhance the low-luminance green and blue channels, resolving the contrast problem while preserving multi-spectral functionality
2Measurement precision
If green and blue image data luminance is increased based on red image data, then contrast and dynamic range are improved, but image processing complexity increases
Solution Approach 1:
The patent changes the luminance parameter of green and blue data by amplification using red data as reference. This parameter transformation improves measurement precision (contrast and dynamic range) through a relatively simple mathematical operation rather than complex processing
Solution Approach 2:
Instead of trying to capture higher luminance directly in green and blue channels (which would require complex hardware modifications), the patent inverts the approach by using the well-captured red channel data to amplify and reconstruct the green and blue channels, achieving high contrast with simpler processing
