Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If image synthesis is always performed, then image quality with wide dynamic range is improved, but processing time and computational load increase unnecessarily
Solution Approach 1:
The patent changes the parameter of image synthesis necessity by introducing brightness distribution analysis. The control device calculates brightness distribution from image signals and compares it against predetermined thresholds to dynamically determine whether synthesis should be performed, transforming a static always-on synthesis approach into a conditional approach based on luminance characteristics
Solution Approach 2:
The system performs self-evaluation by automatically analyzing its own image signals to determine whether synthesis is needed. The control device uses the brightness distribution of captured images to make autonomous decisions about processing requirements, eliminating the need for manual intervention or unnecessary processing
2Manufacturing precision
If image synthesis is performed without determination, then image quality may be improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent applies preliminary action by performing brightness distribution calculation and comparison before the actual image synthesis process. The control device evaluates image signals and determines synthesis necessity in advance, using predetermined determination conditions to guide subsequent processing decisions and avoid unnecessary synthesis operations
Solution Approach 2:
The system implements feedback by using the calculated brightness distribution to control the synthesis process. The control device continuously monitors image signal characteristics and adjusts synthesis operations based on this feedback, creating a closed-loop system that optimizes processing based on actual image content

AI summary
An electronic camera includes: an imaging device that captures a subject image and outputs image signals; an image synthesizing device that performs image synthesis to generate a single image by using a plurality of sets of image signals obtained on different imaging conditions by the imaging device; and a control device that determines whether or not to perform the image synthesis with the image synthesizing device based on a predetermined determination condition, and, when it is determined to perform the image synthesis, controls the image synthesizing device so as to perform the image synthesis.
