Endoscope Image Processing Isolating Noise From Special Light Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing methods for endoscope systems struggle to accurately correct isolated points in special light images without altering the original components of objects, as they rely solely on normal light images, leading to potential omission of important information.
Innovation Solution
An image processing device and method that acquires both normal light and special light images, performs isolated point determination based on pixel values, and controls correction processes on special light images to maintain original object components by blending pixel values according to the degree of isolation, using a combination of normal and special light image information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If isolated point correction is performed on special light images using only normal light image information, then correction can be applied, but original object information may be omitted or altered
Solution Approach 1:
The patent combines normal light image information and special light image information to determine isolated points and control correction processes. The isolated point determination section uses both image types to make comprehensive decisions, ensuring that correction is applied only when necessary while preserving original object information that may appear as isolated points in special light images but are actually valid features.
Solution Approach 2:
The correction control section applies different correction strategies to different regions of the special light image based on the isolated point determination results. When a pixel is determined to be a true isolated point, correction is applied; when it represents original object information, correction is skipped. This localized approach preserves the quality and authenticity of the special light image while removing actual noise.
2Manufacturing precision
If correction process is applied to special light images, then isolated points can be corrected, but the original components of objects may be altered
Solution Approach 1:
The system uses feedback from the normal light image to guide the correction process of the special light image. The isolated point determination section continuously compares pixel values and their surroundings across both image types, and the correction control section adjusts correction application based on this feedback, ensuring that only genuine isolated points are corrected while preserving valid object features.
Solution Approach 2:
The system performs preliminary isolated point determination using both normal and special light images before applying any correction to the special light image. This preliminary analysis identifies which pixels should be corrected and which should be preserved, allowing the correction process to proceed with confidence that original object information will not be altered.
3Device complexity
If only normal light image is used for isolated point determination, then processing is simpler, but important information in special light images may be lost
Solution Approach 1:
The image processing device is designed to handle multiple functions using both normal light and special light images. The same processing pipeline accommodates both image types, with the isolated point determination section universally applying analysis to both images and the correction control section selectively applying corrections based on comprehensive information from both sources, maximizing information preservation.
