Image Processing Apparatus Visible Invisible Spectrum Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing techniques fail to provide visible and invisible images with qualities suitable for independent use, as they typically process mixed images constructed from both spectrums without considering independent correction needs.
Innovation Solution
The image processing apparatus separates visible and invisible images before applying distinct correction processes, ensuring the invisible image quality is equivalent to the visible image quality, using a system with a reading unit and image correction processing unit that includes an image separating unit, gamma correcting unit, spatial filtering unit, and color correcting unit to process each image type separately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If visible and invisible images are processed as a mixed image, then the processing system is simpler, but the image quality for independent use deteriorates
Solution Approach 1:
The patent separates the processing of visible and invisible images into distinct correction units. The visible image correction unit applies corrections optimized for visible spectrum characteristics, while the invisible image correction unit applies corrections optimized for invisible spectrum characteristics. This segmentation allows each image type to receive specialized processing, resolving the contradiction between system simplicity and image quality by organizing complexity in a structured, spectrum-specific manner.
2Manufacturing precision
If different correction processes are applied to visible and invisible images, then image quality is improved, but the processing complexity increases
Solution Approach 1:
The patent implements local quality by applying different correction processes tailored to specific spectrum characteristics. The visible image correction unit applies corrections suited for visible light properties, while the invisible image correction unit applies corrections suited for invisible light properties. This allows each image type to receive locally optimized processing, improving overall image quality while managing complexity through specialized, targeted corrections rather than a single complex universal process.
3Ease of operation
If a single correction process is used for both visible and invisible images, then the processing is simpler, but the suitability for independent use deteriorates
Solution Approach 1:
The patent achieves universality by creating a dual-correction system where both visible and invisible images can be processed independently through their respective correction units. The system maintains versatility by allowing users to obtain either visible images, invisible images, or both separately, each optimized for its specific spectrum. This multi-functional approach resolves the contradiction by providing specialized processing paths that maintain simplicity within each path while enabling versatile independent use of either image type.
