Endoscope Image Processing Dynamic Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscope systems lack the ability to dynamically adjust imaging modes based on the detection of specific targets, leading to inefficient use of observation light and potential degradation of image quality due to inappropriate frame rates and wavelength selection.
Innovation Solution
An image processing apparatus that acquires images using different observation lights and adjusts the imaging mode based on detection results, allowing for dynamic switching between first and second image acquisition modes to optimize frame rates and wavelength usage, ensuring appropriate imaging regardless of target detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multi-frame imaging is performed by sequentially switching between normal light and special light at a determined frame rate, then detection accuracy of region of interest is improved, but frame rate of normal light image decreases
Solution Approach 1:
The patent implements dynamic adjustment of imaging modes by switching between normal light imaging mode and special light imaging mode based on detection results. The system transitions from fixed sequential switching to adaptive dynamic switching, where the imaging mode is adjusted in real-time according to whether a region of interest has been detected, thereby optimizing both detection accuracy and frame rate performance
Solution Approach 2:
The system changes imaging parameters (light type, frame rate, acquisition mode) based on detection outcomes. When a region of interest is detected, the system switches to special light imaging mode with adjusted frame rate, and when not detected, returns to normal light imaging mode with higher frame rate,实现ing parameter optimization based on real-time conditions
2Adaptability or versatility
If observation light is switched according to observation target, then imaging suitability for specific target is improved, but system complexity increases
Solution Approach 1:
The endoscope system integrates multiple imaging functions (normal light imaging, special light imaging, region of interest detection) into a single unified system. The image processing apparatus serves multiple purposes: displaying normal light images for general observation, detecting regions of interest, and controlling mode switching, thereby achieving multi-functionality without requiring separate independent systems
Solution Approach 2:
The system employs feedback mechanisms where detection results from the region of interest detection unit feed back to the mode control unit, which then adjusts the imaging mode accordingly. This closed-loop feedback control enables automatic adaptation to different observation targets and conditions, improving imaging suitability while managing system complexity through intelligent control

AI summary
An image processing apparatus according to a first aspect of the present invention acquires a first image and a second image in a first image acquisition mode, or a second image acquisition mode in which a second image acquisition ratio is higher than in the first image acquisition mode, on the basis of a detection result of a specific target (whether or not a specific target has been detected, what type of specific target). For example, in accordance with whether or not a specific target has been detected and the type of specific target, the first image and the second image can be acquired in the first image acquisition mode in a case where the necessity for acquiring the second image is low, whereas the first image and the second image can be acquired in the second image acquisition mode, in which the second image acquisition ratio is high, in a case where the necessity for acquiring the second image is high.
