Engineering Contradiction Analysis
1Area of stationary object
If a capsule endoscope uses multiple imaging units to image in different directions, then the imaging coverage is improved, but the coordination control of imaging units and light emission units becomes complex, leading to suboptimal image quality at lesioned parts
Solution Approach 1:
The capsule endoscope divides the imaging function into multiple independent imaging units (first imaging unit, second imaging unit) with different imaging directions, and divides the light emission function into separate light emission units. Each unit can be controlled independently, allowing the system to achieve comprehensive imaging coverage while managing complexity through modular control of each segment.
Solution Approach 2:
The system dynamically adjusts the operation state of different imaging units and light emission units based on real-time conditions. When a lesioned part is detected, the system dynamically switches to a state where the imaging unit facing the lesioned part is activated with corresponding light emission, while other units remain inactive, thereby optimizing image quality at critical areas.
2Measurement precision
If the capsule endoscope increases imaging rate when lesioned part is detected, then detection accuracy is improved, but energy consumption increases
Solution Approach 1:
The system employs periodic imaging at normal rates during routine examination, and switches to high-frequency periodic imaging only when a lesioned part is detected. This periodic action pattern allows the system to maintain detection accuracy for critical areas while minimizing energy consumption during normal operation by using lower imaging rates.
Solution Approach 2:
The system applies different imaging rates to different regions: normal imaging rate for general areas and increased imaging rate specifically for detected lesioned parts. This local quality approach ensures high detection accuracy at critical locations while maintaining energy efficiency in non-critical areas.
3Use of energy by moving object
If only the light emission unit in the imaging direction of the imaging unit that is imaging performs light emission, then energy consumption is reduced, but image quality at lesioned parts may be insufficient
Solution Approach 1:
The system dynamically adjusts light emission based on detection results. During normal operation, only the light emission unit corresponding to the active imaging unit operates, conserving energy. When a lesioned part is detected, the system dynamically activates additional light emission units to provide enhanced illumination for high-quality imaging of the lesioned area, thereby maintaining image quality without excessive energy consumption.
Solution Approach 2:
The system provides different light emission levels for different regions: standard light emission for general imaging and enhanced light emission specifically for lesioned parts. This local quality approach ensures sufficient image quality at critical areas while maintaining energy efficiency in non-critical areas.

AI summary
A capsule endoscope or a reception apparatus executes a first light emission motion in which only a light emission module configured to perform light emission in an imaging direction of an imaging module that is performing imaging performs the light emission when no lesioned part is detected and executes a second light emission motion in which a light emission module configured to perform the light emission in a second imaging direction of an imaging module different from an imaging module that is imaging the lesioned part performs the light emission in synchronization with the light emission by a light emission module configured to perform the light emission in a first imaging direction of the imaging module that is imaging the lesioned part when the lesioned part is detected.
