Endoscope Display Control for Lesion Detection Hindrance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope systems face challenges where emphasis displays indicating lesion detection can hinder the observation process for technicians during automatic detection and classification of lesions in endoscopic images.
Innovation Solution
A medical image processing apparatus that includes a recognition unit for detecting and classifying regions of interest, a display control unit for adjusting the emphasis display to reduce visual recognizability, and an observation image switching unit to switch between consecutive and still image display, thereby minimizing the hindrance caused by emphasis displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If emphasis display is displayed to indicate lesion detection, then detection accuracy is improved, but observation quality deteriorates
Solution Approach 1:
The system dynamically adjusts the display mode of emphasis marks based on the current operation state. When the still image operation is detected, the emphasis display is switched from superimposed mode to separate display mode, making the display flexible and adaptive to different operational contexts rather than fixed
Solution Approach 2:
The control unit acts as an intermediary that receives operation information from the operation unit and adjusts the display unit's output accordingly. This intermediary component coordinates between the lesion detection function and the observation function, resolving the conflict by switching display modes based on operational context
2Loss of information
If marker image is superimposed on observation image, then lesion position indication is improved, but image clarity deteriorates
Solution Approach 1:
The display is segmented into two separate modes: when still image operation is not detected, the emphasis mark is superimposed on the observation image to indicate lesion position; when still image operation is detected, the emphasis mark is displayed separately from the observation image. This segmentation allows the system to preserve image quality while still providing lesion position information
Solution Approach 2:
The display parameters of the emphasis mark are changed based on the operation state. The position parameter of the emphasis mark transitions from being superimposed on the image to being displayed in a separate location, changing the spatial parameter to resolve the conflict between information provision and image quality

AI summary
A medical image processing apparatus includes a recognition unit that detects a region of interest from an acquired medical image and classifies the region of interest; a display control unit that causes emphasis display for emphasizing the region of interest and a classification for the region of interest to be displayed in a screen identical to a screen for displaying an observation target included in the medical image; and an observation image switching unit that switches whether to display consecutive images or to display a still image by using a display device. In a case where consecutive image display of an observation image is switched to still image display by the observation image switching unit, the display control unit makes a change for reducing visual recognizability of at least any of the emphasis display or the classification compared with a case of the consecutive image display of the observation image.
