Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the image signal processing unit processes original images to enhance color information for human visual appeal, then the visual quality of images is improved, but profile and line information is lost which reduces recognition accuracy
Solution Approach 1:
The patent segments the image processing task by dividing it into two distinct processing paths: one path processes images for human visual display with color enhancement, while another path processes images for machine recognition with profile and line preservation. This segmentation allows each path to be optimized for its specific purpose without compromising the other.
Solution Approach 2:
The patent applies local quality by using different processing algorithms for different purposes within the same system. For human viewing, color enhancement algorithms are applied, while for machine recognition, algorithms that preserve profile and line information are applied. This ensures that each processing stream has the appropriate quality characteristics for its intended use.
2Device complexity
If a single image processing algorithm is used for all applications, then the system complexity is reduced, but the system cannot satisfy different application requirements such as video shooting and image recognition
Solution Approach 1:
The patent implements dynamics by making the image processing algorithm selection adaptive and dynamic based on the application type. The system dynamically selects between different processing algorithms (color enhancement for video shooting, profile preservation for image recognition) based on the detected application requirements, allowing the system to adapt to different uses without manual reconfiguration.
Solution Approach 2:
The patent applies parameter changes by modifying the processing parameters and algorithm selection based on the application type. Different parameters are adjusted for different applications: color enhancement parameters are used for video shooting, while profile preservation parameters are used for image recognition. This allows a single system to serve multiple purposes by changing processing parameters rather than requiring completely separate hardware systems.
