Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If recovery processing is performed using restoration filters in existing image processing systems, then image quality can be improved, but resolution values of images from multiple imaging systems do not match, leading to inconsistency in image quality
Solution Approach 1:
The patent changes the parameter of resolution value by calculating a target resolution value based on transfer functions and applying it uniformly across multiple imaging systems. The recovery filter is designed to adjust the resolution of each system's output images to match this target value, ensuring consistency while maintaining image quality through controlled parameter adjustment.
Solution Approach 2:
The patent performs preliminary calculation of the target resolution value before executing recovery processing on images from multiple imaging systems. By pre-determining the target resolution based on transfer functions and establishing what the resolution should be, the system ensures that subsequent recovery processing will produce consistent results across all systems.
2Reliability
If a recovery filter is generated based on transfer functions to match resolution values, then resolution consistency across multiple imaging systems is achieved, but the complexity of the processing system increases
Solution Approach 1:
The patent introduces a calculation unit as an intermediary that computes the target resolution value based on transfer functions from multiple imaging systems. This intermediary component processes the transfer functions and generates a unified target resolution value that serves as a reference for all systems, simplifying the overall coordination while achieving resolution matching.
Solution Approach 2:
The recovery filter generation unit is designed to universally handle multiple imaging systems by accepting their respective transfer functions and generating appropriate recovery filters for each system based on a common target resolution value. This multi-functional approach allows a single unit to serve multiple systems without requiring separate complex processing paths for each.
3Manufacturing precision
If the target resolution value is set to maximize resolution, then image detail expression is improved, but the amplification factor exceeds the predetermined threshold value, causing instability
Solution Approach 1:
The patent applies partial action by setting the target resolution value within a controlled range rather than maximizing it completely. The calculation unit determines a target resolution that provides sufficient detail expression while keeping the amplification factor within acceptable thresholds, accepting a slightly lower resolution in exchange for system stability and reliability.
Solution Approach 2:
The patent implements feedback control by using the transfer functions and amplification factors as input to the calculation unit, which then determines an appropriate target resolution value. The system monitors the amplification factor and adjusts the target resolution accordingly to ensure it remains within the predetermined threshold, creating a feedback loop that maintains stability while optimizing image quality.
