Endoscope Image Processing Simultaneous Dual-Light Observation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing endoscope systems cannot simultaneously capture and display both normal light observation and special light observation images of a biological tissue, requiring time-consuming comparison and lacking an image that fully utilizes the characteristics of both types of observations.
Innovation Solution
An image processing device that acquires both normal light and special light observation images simultaneously and processes the normal light image using frequency filters to generate a compositing image, which is then combined with the special light image, enhancing the visibility of superficial and deep tissue structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rotary filter is used to switch between normal light and special light observation, then both observation modes can be achieved, but simultaneous observation of both image types is not possible
Solution Approach 1:
The patent divides the observation modes into two separate imaging paths: one for normal light observation and another for special light observation. Each path has its own filter configuration, allowing both types of images to be captured simultaneously without requiring switching between modes. This segmentation resolves the contradiction by enabling both observation capabilities to operate at the same time rather than sequentially.
2Adaptability or versatility
If normal light observation and special light observation are performed sequentially, then both types of images can be obtained, but they cannot be simultaneously displayed in the same biological tissue
Solution Approach 1:
The patent merges the normally sequential processes of normal light observation and special light observation into a simultaneous operation. By combining both imaging paths and integrating their outputs, the system captures and displays both image types at the same time, eliminating the sequential delay and improving productivity while maintaining both observation capabilities.
3Loss of information
If separate display of normal light and special light images is used, then both images can be observed, but time-consuming comparison is required and full utilization of both characteristics is not achieved
Solution Approach 1:
The patent combines normal light images and special light images into a single composite display that shows both types of information simultaneously overlaid on the same biological tissue view. This merging eliminates the need for separate display and manual comparison, allowing the observer to utilize the full characteristics of both imaging modes at once without time loss.
Solution Approach 2:
The patent applies different processing and weighting to different regions or aspects of the combined image, enhancing specific features from each observation type in appropriate locations. Normal light information may be emphasized in certain areas while special light information is enhanced in others, allowing optimal utilization of each mode's characteristics throughout the composite image.

AI summary
An image processing device includes an image acquisition unit for acquiring a normal light observation image captured with white light and a special light observation image captured simultaneously with the normal light observation image using predetermined narrowband light, and an image processing unit for subjecting the normal light observation image acquired by the image acquisition unit to predetermined processing to generate a processed normal light observation image and providing information of the processed normal light observation image to the special light observation image.
