Endoscopic Lesion Position Display Using Peripheral Reference Marks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In endoscopic imaging, there is a challenge in accurately tracking and displaying the position of a lesioned part within an endoscopic image, as the relative positional relation between the endoscope tip and the lesion changes, making it difficult for users to maintain a clear overview of the detection state.
Innovation Solution
An endoscopic image processing apparatus that detects lesion regions, acquires lesion information, determines the presence of lesions, and generates display images with marks indicating the detection state of lesions in predefined regions outside the main image, using a processor to manage lesion detection, determination, and display control units.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the endoscope is moved to track the lesion, then the lesion position can be followed, but the relative positional relation changes and the overview of detection state is lost
Solution Approach 1:
The display screen is divided into multiple regions: a main endoscopic image display region and multiple mark display regions arranged around it. Each mark display region corresponds to a specific reference region in the endoscopic image, allowing the lesion position to be tracked in one region while maintaining overview information in other regions.
Solution Approach 2:
Marks are introduced as intermediary visual elements that mediate between the lesion position in the endoscopic image and the user's understanding of detection state. These marks are displayed in predetermined mark display regions and indicate which reference region contains the lesion, providing a clear overview without requiring direct manipulation of the endoscopic image view.
2Loss of information
If multiple marks are displayed to show detection state, then overview information is provided, but the display screen becomes cluttered
Solution Approach 1:
The detection state information is extracted from the main endoscopic image and placed into separate mark display regions arranged around the periphery. This separates the overview information from the detailed image view, preventing clutter while maintaining information availability.
Solution Approach 2:
Instead of displaying multiple marks overlaid on the two-dimensional endoscopic image (which would cause clutter), the marks are arranged in a different spatial dimension around the periphery of the screen. This transforms the display layout from a flat overlay to a spatial arrangement that utilizes the available screen real estate more efficiently.
3Measurement precision
If the lesion position changes frequently, then accurate tracking is needed, but user burden increases
Solution Approach 1:
The system automatically updates the mark display regions based on the detected lesion position in each frame. The processor determines which reference region contains the lesion and automatically generates the appropriate mark display, eliminating the need for manual tracking operations by the user.
Solution Approach 2:
The mark display regions provide immediate visual feedback about the current detection state corresponding to the lesion position. When the lesion moves to a different reference region, the mark display automatically updates to reflect this change, giving the user real-time information without requiring active tracking efforts.

AI summary
An endoscopic image processing apparatus includes a processor. The processor performs processing for acquiring lesion information including information indicating a position of a lesion region included in an endoscopic image, determines whether the lesion region is included in the endoscopic image, and performs processing for generating a display image for displaying one or more marks in at least one of N mark display regions set as regions as many as a maximum display number of the one or more marks, and generating the one or more marks indicating in which reference region among a predetermined plurality of reference regions set in the endoscopic image a present position of the lesion region or a position of the lesion region immediately before the detection is interrupted is included and displaying the one or more marks in at least one of the N mark display regions.
