Capsule Endoscope Image Correction via Posture Sensor Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing capsule endoscopes face challenges in maintaining a stable image orientation within the body, leading to discomfort and misinterpretation of images due to arbitrary rotation, which complicates diagnosis.
Innovation Solution
Incorporating an image sensor and a posture sensor coupled with a processor that calculates and corrects the screen rotation angle based on three-axis data, ensuring the image axes align with the actual vertical and horizontal axes, thereby stabilizing the image displayed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the capsule endoscope is placed in the body to diagnose, then the diagnosis function is achieved, but the image orientation becomes unstable and rotates arbitrarily
Solution Approach 1:
The patent applies feedback by using the posture sensor to continuously detect the capsule's orientation and feeding this information back to the processor, which then automatically rotates the image to maintain proper orientation. This closed-loop system ensures stable image presentation despite arbitrary capsule movement in the body.
Solution Approach 2:
The system performs self-correction by automatically detecting its own posture through the posture sensor and autonomously rotating the image without external intervention. The capsule endoscope self-adjusts its image orientation based on real-time posture data, eliminating the need for manual adjustment.
2Adaptability or versatility
If the capsule endoscope rotates arbitrarily in the body, then the capsule can move freely, but the image becomes difficult to identify and may cause discomfort
Solution Approach 1:
The patent implements dynamics by making the image rotation angle adjustable and responsive to real-time posture changes. The system dynamically adapts the image orientation to match the capsule's current position and attitude, allowing free movement while maintaining accurate and stable image presentation.
3Device complexity
If no image correction is applied, then the device structure remains simple, but the operator cannot effectively grasp the capsule posture and may make misjudgments
Solution Approach 1:
The patent applies universality by making the processor perform multiple functions: it processes image data from the image sensor, posture data from the posture sensor, calculates rotation angles, and executes image rotation. This multi-functional approach adds image correction capability without requiring separate dedicated hardware for each function.
Data Source
AI summary
A capsule endoscope, an endoscope system, and an image correction method are provided. The capsule endoscope includes an image sensor and a posture sensor. The image sensor is coupled to a processor and obtains a sensed image. The posture sensor is coupled to the processor and obtains three-axis data. The processor calculates a screen rotation angle according to the three-axis data and corrects the sensed image according to the screen rotation angle. A first axis and a second axis of the corrected sensed image rotate toward an actual vertical axis and an actual horizontal axis.
