Solution Overview
Problem
Current video endoscopes lack real-time detection capabilities for subtle image irregularities, which can lead to suboptimal examination quality due to undetected defects.
Innovation Solution
Implement an image processor with an evaluation unit that utilizes conventional image processing and convolutional neural networks (CNNs) to analyze video endoscopic images for irregularities, issuing notifications for corrective actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional image processing alone is used, then device complexity is low, but measurement precision for detecting subtle image irregularities is insufficient
Solution Approach 1:
The evaluation unit segments the image analysis task into two distinct processing paths: conventional image processing for basic analysis and convolutional neural networks for advanced pattern recognition. This segmentation allows each method to handle specific types of irregularities optimally, improving overall detection precision without requiring a complete system overhaul
Solution Approach 2:
The convolutional neural network acts as an intermediary component between the image processor and the evaluation unit. It receives preprocessed images, performs complex pattern recognition, and outputs detection results that enhance the capabilities of the conventional evaluation unit, thereby improving measurement precision while maintaining manageable system complexity
2Productivity
If real-time detection is implemented, then productivity is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The system performs preliminary image processing and preprocessing before the main evaluation stage. By preparing images in advance and extracting relevant features beforehand, the system reduces the computational burden during real-time detection, enabling faster processing speeds without proportionally increasing device complexity
Solution Approach 2:
The evaluation unit dynamically adjusts processing parameters and detection thresholds based on image characteristics and detected irregularities. This dynamic adaptation allows the system to optimize processing speed for different types of examinations while maintaining detection accuracy, thereby improving productivity without requiring maximum processing power for all cases

AI summary
A method for detecting an image irregularity in one or more still images or video images produced by an endoscopic instrument. The method including: producing the one or more still images or video images; transmitting the one or more still images or video images to a processor comprising hardware; detecting, with the processor, a presence or an absence of the image irregularity in the one or more still images or video images; and where the presence of the image irregularity is detected, issuing a notification to a user about the presence of the image irregularity.
