Endoscope System Dynamic Image Adjustment for Insertion and Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Endoscope systems face challenges in improving manipulability during insertion and ease of observation during removal, as existing technologies do not effectively adapt image acquisition and display based on the movement direction and mode of the insertion portion within the body cavity.
Innovation Solution
An endoscope system that includes an insertion/removal detector to determine the relative movement direction, an image generator to process and adjust image information accordingly, and an image display part to show images optimized for the movement mode, with adjustable frame rates and pixel addition based on insertion or removal states, and optional inclusion of distance information during insertion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the frame rate is increased during insertion to improve manipulability, then the smoothness of image display is improved, but the image resolution and detail quality deteriorate
Solution Approach 1:
The system dynamically adjusts the frame rate of the image acquisition part based on the movement state of the insertion portion. During insertion, the frame rate is increased to provide smooth real-time feedback for manipulation, while during removal, the frame rate is reduced to prioritize image quality and detail observation. This dynamic parameter adjustment resolves the contradiction between operational smoothness and image resolution.
2Speed
If the frame rate is increased during insertion to improve manipulability, then the responsiveness of image display is improved, but the data processing load and energy consumption increase
Solution Approach 1:
The system employs periodic variation in frame rate based on operational phase. During insertion, a higher frame rate is maintained to ensure responsiveness, while during removal, the frame rate is reduced. This periodic adjustment of operational parameters balances responsiveness requirements with energy consumption constraints throughout the endoscope procedure.
3Productivity
If the insertion portion moves quickly during insertion to improve efficiency, then the productivity is improved, but the image quality and observation accuracy deteriorate
Solution Approach 1:
The system dynamically adapts image acquisition parameters to the movement state. When the insertion portion moves quickly during insertion, the high frame rate captures the motion smoothly for operational guidance. When movement slows during removal for observation, the system prioritizes image quality and detail capture. This dynamic adaptation resolves the contradiction between insertion speed and observation accuracy.

AI summary
For the purpose of improving the manipulability at the time of insertion and improving the ease of observation at the time of removal, according to the movement direction of an insertion portion with respect to a body cavity and a movement mode thereof, an endoscope system includes: an endoscope that is provided with an insertion portion that is inserted into a body cavity and an image acquisition part that acquires, at the distal end of the insertion portion, an image of the inside of the body cavity; an insertion/removal detector that detects a relative movement direction of the insertion portion with respect to the body cavity; an image generator that generates image information suitable for a movement mode of the insertion portion based on the relative movement direction detected by the insertion/removal detector; and an image display part that displays the image information generated by the image generator.
