Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The visual recognition of display symbols on patterned backgrounds can be insufficient due to factors such as overly dark patterns, low clarity, and chromaticity differences, making it difficult to distinguish the display symbols from the background.
Innovation Solution
A visual recognition determination system that calculates features like clarity, mark visual angle, and chromaticity difference to determine the visibility of display subjects on patterned panels, using logistic regression analysis to predict satisfactory recognition and adjust illumination patterns as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If light is emitted from a light source onto a back surface of a panel with a patterned background, then the display subject can be shown on the panel, but the visual recognition of the display subject may be insufficient when the pattern is overly dark
Solution Approach 1:
The patent changes the chromaticity parameters of the light source to optimize visual recognition. By adjusting the color temperature and spectral composition of the illuminating light, the system enhances the contrast between the display subject and the patterned background, thereby improving clarity without increasing overall intensity
Solution Approach 2:
The patent applies different chromaticity characteristics to different regions of the illumination spectrum. By selectively enhancing certain wavelength ranges that improve subject-background differentiation, the system achieves localized optimization of visual recognition in critical areas while maintaining overall illumination balance
2Shape
If the pattern on the background is made darker to enhance contrast, then the aesthetic appearance may be improved, but the contour of the display symbol may not be recognized
Solution Approach 1:
The patent adjusts the chromaticity parameters of the illuminating light to compensate for the dark pattern background. By modifying the color temperature and spectral power distribution, the system enhances the perceived brightness and contour definition of display symbols against dark patterns, resolving the recognition issue while preserving the aesthetic dark pattern design
3Measurement precision
If chromaticity difference between the display subject and background is increased, then visual distinction may be improved, but the overall aesthetic harmony may be compromised
Solution Approach 1:
The patent precisely adjusts chromaticity parameters within optimal ranges to achieve sufficient visual distinction while maintaining aesthetic harmony. By controlling the degree of chromaticity adjustment and selecting appropriate color temperature ranges, the system enhances subject-background differentiation without creating jarring color contrasts that would compromise overall aesthetic composition

Data Source
AI summary
A visual recognition determination system is configured to determine visual recognition of a display subject when light is emitted from a light source onto a back surface of a panel, in which the display subject is formed. The light transmitted through the display subject shows the display subject on a pattern on the panel. The pattern serves as a background of the display subject. The visual recognition determination system includes a determination unit that determines the visual recognition of the display subject based on a feature representing a clarity of the pattern on the panel.
