Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a movable mechanism is used to compensate for lens or CCD movement, then anti-shake function is improved, but device complexity and cost increase due to additional mechanical modules
Solution Approach 1:
The patent replaces the mechanical anti-shake system with a digital image processing system. Instead of using movable mechanisms to physically compensate for lens or CCD movement, the patent uses software algorithms to process and correct the captured images, eliminating the need for complex mechanical modules while maintaining anti-shake functionality
Solution Approach 2:
The patent captures multiple images of the same scene and uses image processing to select or combine the clearest image. By taking multiple copies (images) and processing them digitally, the system achieves anti-shake效果 without mechanical movement compensation
2Device complexity
If digital image processing is used to reduce blur pitch, then device complexity is reduced, but processing time increases
Solution Approach 1:
The patent applies selective image processing only to specific regions or uses simplified algorithms that process only the necessary portions of images. By performing partial processing rather than full-image complex processing, the system reduces processing time while still achieving effective blur reduction in critical areas
Solution Approach 2:
The patent performs preliminary image capture and basic processing in advance, preparing multiple candidate images before final selection or combination. This preliminary action allows the system to have pre-processed images ready, reducing the time needed for final anti-shake processing

AI summary
An electronic device includes a camera module and an image module. The camera module captures a number of static images of an object. The image module includes a detecting unit and an image combining unit. The image module detects an edge response value of each image. The image combining unit selects and combines two images having maximum edge response values in turn according to a rate of the edge response values.
