Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems require sequential determination of multiple process conditions for image adjustment processing, leading to increased processing time and potential degradation in efficiency.
Innovation Solution
An image processing apparatus and method that prioritize process conditions, allowing for efficient judgment and execution of image adjustment processing by determining whether image components satisfy process conditions in order of priority, with higher priority given to conditions that do not require image adjustment processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple process conditions are determined sequentially to ensure comprehensive image adjustment processing, then the completeness of image processing is improved, but the processing time increases and efficiency deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing a priority order for multiple process conditions before actual image processing occurs. The system stores priority information indicating the determination order of process conditions in advance, so when image components are processed, the system can quickly evaluate conditions in the predetermined priority sequence without performing exhaustive sequential checks, thus reducing processing time while ensuring comprehensive coverage of necessary adjustments.
2Measurement precision
If all process conditions are evaluated to ensure accurate process content selection, then the accuracy of processing decisions is improved, but the determination time increases
Solution Approach 1:
The system performs preliminary action by pre-defining and storing priority information that specifies the determination order of process conditions. This allows the determination unit to evaluate conditions in a predetermined sequence, stopping once the first satisfied condition is found, thereby maintaining accurate process content selection while significantly reducing determination time compared to evaluating all conditions exhaustively.
Solution Approach 2:
The patent extracts and utilizes only the necessary process conditions by implementing a priority-based evaluation system. Instead of evaluating all possible process conditions, the system extracts and evaluates conditions in priority order, taking out only the relevant conditions that need to be checked first, thus reducing determination time while maintaining accuracy in process content selection.
3Adaptability or versatility
If a rule base with multiple process conditions is accessed to handle various image adjustment scenarios, then the versatility of the system is improved, but the complexity of the determination process increases
Solution Approach 1:
The system reduces determination process complexity by performing preliminary action - pre-establishing and storing priority information that defines the evaluation sequence of process conditions. This pre-organization allows the determination unit to systematically evaluate conditions in a predetermined order, making the complex rule base more manageable and reducing the cognitive and computational complexity of the determination process while maintaining versatility in handling various image adjustment scenarios.
