Solution Overview
Problem
Conventional endoscopic systems confuse operators by synchronizing camera movements with image display angle changes, making it difficult to maintain a fixed viewing angle during procedures.
Innovation Solution
An endoscopic image correction system that includes an image retrieving device, a processing device, and a display device, which calculate and maintain a consistent image display angle by determining the angular difference between image picture-taking and display angles, using a position sensor like a G-sensor to ensure continuous, dynamic image display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the camera movements are synchronized with image display angle changes, then the image display reflects real-time camera position, but the operator becomes confused and cannot correctly determine camera position and direction
Solution Approach 1:
The patent inverts the conventional approach by decoupling the camera's physical movement from the image display angle. Instead of the display angle following the camera angle (conventional approach), the system calculates a corrected display angle that compensates for camera movement, effectively doing the opposite of direct synchronization. This inversion resolves the contradiction by maintaining image stability while allowing camera movement, thereby improving operator orientation without sacrificing image display accuracy.
Solution Approach 2:
The patent introduces an intermediary calculation process that acts as a mediator between the camera's actual angle and the displayed image angle. The processing device calculates a corrected display angle based on the relationship between first and second image angles, serving as an intermediary that transforms the raw camera angle data into a stabilized display angle. This intermediary mechanism resolves the contradiction by filtering out the confusing direct correlation between camera movement and display angle changes.
2Adaptability or versatility
If the camera moves inside the human body, then the system can capture images from different positions, but the viewing angle becomes unstable and difficult to maintain
Solution Approach 1:
The patent applies dynamics by creating a dynamic correction mechanism that continuously adjusts the display angle based on real-time camera angle changes. The system retrieves first and second images at different times, calculates the angular difference, and dynamically updates the corrected display angle to compensate for camera movement. This dynamic approach maintains viewing angle stability while allowing the camera to move freely to different positions inside the human body.
Solution Approach 2:
The patent changes the parameter of display angle from a fixed value to a dynamically corrected value based on camera angle variations. By calculating the difference between first and second image angles and applying this difference as a correction to the corrected display angle, the system transforms the static viewing angle parameter into an adaptive parameter that automatically compensates for camera movement, thereby maintaining stability while enabling positioning flexibility.
