Endoscope Image Processing Lesion Discrimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical image processing systems face challenges in providing detailed information for diagnosing the type and progress of lesions, which is a heavy burden for doctors, and existing technologies do not adequately support discrimination beyond basic analysis.
Innovation Solution
A medical image processing apparatus and endoscope apparatus that utilize multiple illumination lights with different spectra to capture and analyze medical images, with a first discrimination process using white light and a second process using narrower wavelength band light, such as blue or violet, to provide more detailed discrimination results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If multiple discrimination processes with different illumination lights are performed, then the information detail about lesions is improved, but the device complexity increases
Solution Approach 1:
The discrimination process is divided into multiple independent stages: first discrimination process using first illumination light, second discrimination process using second illumination light with different spectrum, and third discrimination process using third illumination light. Each process targets specific lesion characteristics, allowing comprehensive information extraction while maintaining modular system architecture that manages complexity.
Solution Approach 2:
The medical image processing apparatus is designed to perform multiple discrimination processes using different illumination lights (white light, blue light, violet light, narrow-band light) within a single integrated system. The apparatus can selectively apply different discrimination processes based on lesion type and progression stage, providing universal diagnostic capability across various medical conditions.
2Measurement precision
If multiple discrimination processes are performed to provide detailed information, then the diagnostic accuracy is improved, but the processing time increases
Solution Approach 1:
The system performs a first discrimination process using white light illumination to identify basic lesion characteristics and progression stage before proceeding to more specialized discrimination processes. This preliminary assessment allows the system to selectively apply subsequent discrimination processes only when needed, reducing overall processing time while maintaining diagnostic accuracy.
Solution Approach 2:
The medical image processing apparatus dynamically adjusts the sequence and combination of discrimination processes based on the characteristics detected in previous stages. The system can adaptively select which discrimination processes to perform next, optimizing processing time while ensuring comprehensive diagnostic information is obtained.

AI summary
A medical image processing apparatus includes one or more processors configured to control a light source to intermittently switch illumination light emitted from an endoscope between first illumination light and second illumination light having a spectrum different from the first illumination light at a predetermined timing; acquire first medical images using the first illumination light and second medical images using the second illumination light; display the first medical images sequentially on a monitor; perform a discrimination process of discriminating a type or a degree of progress of a lesion in at least one of the second medical images during when at least one of the first medical images is displayed on the monitor; display a discrimination result of the lesion discriminated in the discrimination process with at least one of the first medical images on the monitor, wherein the first medical images are medical images captured using white light.
