Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple cameras are driven to acquire images with different fields of view, then image quality and zoom capability are improved, but power consumption and memory consumption increase
Solution Approach 1:
The system performs preliminary actions by acquiring images from multiple cameras simultaneously before processing, then selects only the necessary images based on zoom magnification requirements. This allows the system to maintain the capability of using multiple cameras for high quality images while avoiding continuous processing of all images, thereby reducing power consumption.
Solution Approach 2:
The patent applies partial action by selectively processing only certain images from the multiple cameras based on the specific zoom magnification needed. Instead of processing all images from all cameras in all situations, the system processes only the portion of images required for the current viewing requirement, reducing unnecessary power and memory usage.
2Use of energy by moving object
If multiple cameras are selectively turned on and off based on field of view, then power consumption is reduced, but time delay and interruption occur during image switching
Solution Approach 1:
The system performs preliminary action by acquiring images from multiple cameras in advance before switching is needed. By having images already captured and stored from all cameras, the system can switch between them instantly based on zoom magnification requirements without the delay of turning cameras on and off, thus eliminating time delay while still managing power consumption through selective processing.
3Adaptability or versatility
If all images from multiple cameras are processed, then comprehensive image coverage is achieved, but processing time and computational resources increase
Solution Approach 1:
The patent applies partial action by processing only the necessary subset of images based on the current zoom magnification requirement. When zoom level indicates a need for wide-angle view, only wide-angle camera images are processed; when telephoto is needed, only telephoto images are processed. This maintains comprehensive image coverage capability while significantly improving processing efficiency by avoiding unnecessary computation.
Solution Approach 2:
The system applies local quality by tailoring the processing to the specific local requirement of zoom magnification. Different processing paths are applied based on the local viewing requirement - wide-angle processing for distant views, telephoto processing for close-up views. This ensures appropriate image coverage for each situation while optimizing processing efficiency for that specific local context.
