Endoscope Image Acquisition System with Wavelength Pattern Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing endoscopic image acquisition systems face challenges in efficiently collecting training images, as frequent changes in display color due to different wavelength patterns increase the doctor's workload and examination time, making it difficult to observe images effectively.
Innovation Solution
The system captures images of multiple wavelength patterns at a certain frame rate, storing only the latest image of the observation wavelength pattern and interpolating or displaying images captured before the latest one, while storing images of different wavelength patterns in separate storage areas, allowing for easier observation and efficient data management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If images of multiple wavelength patterns are captured sequentially to collect training images, then the quantity of training images is improved, but the display color changes frequently making observation difficult
Solution Approach 1:
The patent segments the image data by storing images of different wavelength patterns in separate storage areas (first storage area for observation wavelength pattern, second storage area for other wavelength patterns). This segmentation allows the display to show only relevant images without color confusion while maintaining access to all captured training images.
Solution Approach 2:
The patent introduces a display control unit as an intermediary between the storage unit and the display. This mediator selectively retrieves and displays only images from the first storage area (observation wavelength pattern) when the observation wavelength pattern is selected, filtering out images from the second storage area that would cause color confusion.
2Quantity of substance
If images of multiple wavelength patterns are captured sequentially, then training image collection is improved, but the examination time increases
Solution Approach 1:
The patent performs preliminary action by capturing and storing images of multiple wavelength patterns in advance during the examination. The images are stored in organized storage areas before the learning algorithm training begins, so that when training is needed, the images are already prepared and readily available without requiring additional time during the actual training process.
Solution Approach 2:
The patent enables continuous capture of images at a certain frame rate for the observation wavelength pattern while simultaneously capturing images of other wavelength patterns. Both processes run in parallel without interrupting each other, maximizing the efficiency of image collection during the examination.
3Quantity of substance
If images of multiple wavelength patterns are captured sequentially, then training image collection is improved, but the doctor's workload increases
Solution Approach 1:
The patent implements self-service by introducing an automatic determination unit that automatically determines whether a captured image should be stored in the first or second storage area based on whether its wavelength pattern matches the observation wavelength pattern. This eliminates the need for the doctor to manually sort and categorize images by wavelength pattern, significantly reducing the doctor's workload.
Solution Approach 2:
The patent uses feedback by having the automatic determination unit continuously monitor the wavelength pattern of captured images and automatically route them to the appropriate storage area. This automated feedback loop ensures proper organization of images without requiring manual intervention from the doctor.

AI summary
Provided are endoscopic image acquisition system and method that make observation of images easier when images are collected. The endoscopic image acquisition system includes a wavelength pattern changing unit that changes a wavelength pattern of irradiation light with which a part to be observed in a body cavity of a patient is irradiated or returning light from the part to be observed. Images of an observation wavelength pattern are captured at a certain frame rate. In response to acceptance of an acquisition instruction, images of a plurality of wavelength patterns different from one another are sequentially captured. The images of the plurality of wavelength patterns different from one another are stored in a storage unit. An image of a wavelength pattern other than the observation wavelength pattern is set not to be displayed.
