Endoscopic Image Processing for Lesion Detection Cessation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscope systems face challenges in effectively displaying assisting information for regions of interest that have ceased to be detected, leading to potential overlooking of lesions during examinations.
Innovation Solution
An endoscopic image processing apparatus that includes a processor to acquire images, detect regions of interest, determine if detection has ceased, and perform a display propriety determination to decide whether to display assisting information, outputting images with or without assisting information based on this determination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If assisting information is always displayed for regions of interest that have ceased to be detected, then the operator is reminded of disappeared lesions, but the screen may be cluttered and other lesions may be hidden
Solution Approach 1:
The system changes the display parameters of assisting information dynamically based on the detection status of other regions. When a new region of interest is detected, the system adjusts whether to display assisting information for previously disappeared regions, transforming the display state from static to adaptive, thus resolving the contradiction between reminder effectiveness and screen clarity
Solution Approach 2:
The display of assisting information is made dynamic rather than static. The system continuously monitors detection status and automatically adjusts the display state of assisting information based on current observation conditions, allowing the interface to adapt to changing examination scenarios and prevent information overload
2Device complexity
If assisting information is not displayed when regions of interest cease to be detected, then the screen remains clear, but the operator may overlook disappeared lesions
Solution Approach 1:
The system implements a feedback mechanism where the detection status of regions of interest continuously informs the display state of assisting information. When detection ceases for a region, the system provides feedback by displaying assisting information to remind the operator, ensuring that important lesions are not overlooked while maintaining screen simplicity through conditional display
3Adaptability or versatility
If multiple types of information are displayed simultaneously, then comprehensive examination assistance is provided, but the operator burden increases and important information may be lost
Solution Approach 1:
The system applies local quality by providing different display treatments to different types of information based on their importance and context. Assisting information for disappeared regions is displayed with distinct visual characteristics and only in specific situations, allowing comprehensive information provision while maintaining operator ease through differentiated, context-appropriate display strategies

AI summary
An endoscopic image processing apparatus includes an image acquiring unit, a region-of-interest detection unit, a detection cessation determination unit, a display determination unit, and a display output unit. The detection cessation determination unit determines whether a detection of a region of interest in the region-of-interest detection unit has ceased. The display determination unit performs a display propriety determination as a determination of whether to display assisting information on a display unit, when a cessation determination is acquired in the detection cessation determination unit. The assisting information is information for assisting the region of interest, the detection of which has ceased, to be restored on a screen of a display unit.
