Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the system is upgraded from 10-bit to 12-bit image quality processing, then the output accuracy and bit depth capability are improved, but the device complexity, memory requirements, and calculation logic increase significantly
Solution Approach 1:
The patent segments the image signal into upper bit components and lower bit components, processing them through different pathways. The upper bit image signal undergoes full image quality processing while the lower bit image signal is handled separately and then combined, thereby managing system complexity while maintaining 12-bit output accuracy
Solution Approach 2:
The patent applies different processing strategies to different parts of the image signal based on local characteristics. By analyzing image parameters and applying area-based processing, the system optimizes computational resources and reduces overall system complexity while maintaining high output accuracy where needed
2Adaptability or versatility
If the system is converted to 12-bit image quality processing, then the processing capability for high-bit image signals is improved, but the developing time and verification requirements increase
Solution Approach 1:
By dividing the processing into separate upper bit and lower bit pathways, the system can be developed and verified in modular sections rather than as a monolithic 12-bit processor, reducing overall development time while maintaining full processing capability
Solution Approach 2:
The patent performs preliminary analysis of image parameters and determines processing strategies in advance based on image characteristics. This preliminary action allows the system to prepare appropriate processing paths before actual image quality processing, reducing real-time computational burden and simplifying verification
3Manufacturing precision
If the memory and calculation logic are increased to support 12-bit processing, then the image quality processing capability is improved, but the manufacturing cost and system resources increase
Solution Approach 1:
The patent segments the image signal processing into upper bit and lower bit components that can be handled with different resource allocations. This segmentation allows the system to achieve 12-bit output quality without requiring full 12-bit processing resources throughout the entire pipeline, thereby reducing memory and calculation logic requirements
Solution Approach 2:
By applying area-based processing strategies, the system concentrates computational resources on regions requiring high precision while using simpler processing for other areas, optimizing the use of memory and calculation logic resources while maintaining manufacturing precision
