Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current digital image processing technologies lack the capability to effectively capture and reproduce non-visible features at desired locations, particularly in medical and object visualization applications, where simultaneous visibility of both non-visible and visible features is necessary.
Innovation Solution
An image system comprising a light valve with individually addressable pixels and an image capturing unit with correlated detector pixels, allowing for the correlation between light valve and detector pixels to capture and reproduce images, enabling the visualization of non-visible features at desired locations and facilitating medical treatments or object camouflage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional digital image processing is used, then visible images can be captured, but non-visible features cannot be visualized at desired locations
Solution Approach 1:
The patent creates a visible copy of non-visible features by capturing non-visible images (e.g., infrared) and reproducing them as visible images on a display surface. The light valve projects the captured non-visible feature image onto a display target, creating a visual copy that can be simultaneously viewed with the visible scene, thus resolving the information loss problem.
Solution Approach 2:
The light valve acts as an intermediary device that receives non-visible images from the detector and transforms them into visible projections. This intermediary system bridges the gap between non-visible detection and visible observation, enabling simultaneous viewing of both non-visible features and the visible scene without direct observation of the non-visible features themselves.
2Measurement precision
If the light valve projects images onto surfaces, then non-visible features become visible, but the object's original appearance may be obscured
Solution Approach 1:
The light valve projects the non-visible feature image onto specific localized areas of the display target corresponding to where the non-visible features are located. This localized projection approach ensures that only the regions containing non-visible features are highlighted, while other areas maintain their original visibility, thus preserving background visibility while achieving precise feature location.
3Measurement precision
If the system captures and reproduces images at desired locations, then visualization accuracy improves, but system complexity increases
Solution Approach 1:
The patent replaces complex mechanical alignment systems with a computational correlation approach. Instead of using精密 mechanical positioning mechanisms to align the light valve and detector, the system uses pixel correlation mapping that can be established through software processing of the relative positions and orientations of the two components. This substitution of mechanical alignment with computational correlation reduces mechanical complexity while maintaining alignment accuracy.
