Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If pixel shift processing is applied to obtain high definition images, then image resolution is improved, but frame rate decreases and motion smoothness deteriorates
Solution Approach 1:
The patent implements dynamic switching between pixel shift processing mode and normal imaging mode based on real-time detection of motion magnitude in the imaged subject. When motion exceeds a threshold, the system automatically transitions from high-definition pixel shift mode to standard imaging mode, thereby adapting the frame rate to match the motion characteristics and maintaining smooth motion representation without unnecessary resolution enhancement.
Solution Approach 2:
The system changes the processing parameter (pixel shift processing enabled/disabled) based on the detected motion state of the surgical scene. By monitoring motion magnitude and adjusting the imaging mode accordingly, the system optimizes the balance between resolution and frame rate dynamically throughout the surgical procedure.
2Measurement precision
If pixel shift processing is applied continuously, then high definition images are obtained, but processing time increases and surgical efficiency decreases
Solution Approach 1:
The system dynamically adjusts processing intensity based on surgical scene characteristics. By detecting motion magnitude and selectively applying pixel shift processing only when appropriate (low motion periods), the system reduces overall processing time while maintaining high definition quality during critical static moments, thereby improving surgical workflow efficiency.
Solution Approach 2:
Instead of continuously applying pixel shift processing, the system applies it partially—only during periods when motion is below the threshold. This selective application reduces cumulative processing time and computational load while still providing high definition images during stable surgical phases, optimizing the trade-off between image quality and surgical productivity.
