Endoscope Apparatus Automatic Two-Screen Display Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current endoscope systems require manual operation by surgeons to switch between surgical and gastrointestinal images for two-screen display, which can be cumbersome and time-consuming, especially when determining if the gastrointestinal endoscope has reached the target region.
Innovation Solution
An endoscope apparatus with an input portion for receiving surgical and gastrointestinal images, a display image selecting portion for outputting either or both images, and a processor that detects high-luminance areas from illumination light in the surgical image to automatically switch to two-screen display when the gastrointestinal endoscope reaches the target region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual operation is used to switch between surgical and gastrointestinal images for two-screen display, then the surgeon can control the display mode, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The system automatically detects the gastrointestinal endoscope's position by analyzing illumination light areas in the surgical image and autonomously switches to two-screen display mode without requiring surgeon intervention. This self-service mechanism eliminates manual operation steps while maintaining appropriate display modes based on real-time detection results
Solution Approach 2:
The system continuously monitors the surgical image for high-luminance areas indicating the gastrointestinal endoscope's illumination light, uses this feedback to determine when the target region is reached, and automatically adjusts the display mode accordingly. This closed-loop feedback system ensures timely switching based on actual procedural status
2Measurement precision
If the surgeon manually determines when the gastrointestinal endoscope has reached the target region, then accuracy can be maintained, but the procedure progression is delayed
Solution Approach 1:
The system replaces the surgeon's manual visual detection and judgment with an automated image processing system that analyzes luminance patterns in the surgical image. This substitution maintains detection accuracy through algorithmic identification of illumination light characteristics while significantly accelerating the determination process
Solution Approach 2:
The image processing system acts as an intermediary between the gastrointestinal endoscope and the display control system. It automatically detects the endoscope's position by analyzing illumination light areas and triggers the display mode switch, eliminating the need for direct surgeon intervention and enabling smoother procedure progression
3Extent of automation
If automatic detection of illumination light areas is implemented, then the switching to two-screen display becomes automatic and timely, but the device complexity increases
Solution Approach 1:
The image processing system performs multiple functions: it monitors the surgical image for illumination light areas, determines when the target region is reached, and controls the display mode switching. By consolidating these functions into a single multi-functional module, the system achieves high automation without proportionally increasing overall device complexity
Solution Approach 2:
The system merges the detection function and display control function into an integrated automated system. The image processing unit combines illumination light detection, position determination, and display mode control operations, reducing the need for separate components and minimizing the increase in device complexity while maximizing automation

AI summary
An endoscope apparatus includes: a display image selecting portion that selectively outputs one of a surgical image and a gastrointestinal image inputted via an input portion or outputs both of the surgical image and the gastrointestinal image; a combining portion that generates, when both of the surgical image and the gastrointestinal image are outputted by the display image selecting portion, a composite image for performing two-screen display of the surgical image and the gastrointestinal image; and a processor that performs image judgment processing, the processor detecting whether a high-luminance area formed by illumination light radiated at a time of image pickup by the gastrointestinal endoscope exists in the surgical image; and deciding, when detecting that the high-luminance area exists in the surgical image when the surgical image is displayed in one screen, a display method for causing two-screen display based on the composite image to be displayed.
