Multi-layer LCD Imaging for Glare Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sun glare in urban driving environments can hinder visibility of important features like traffic signals, road signs, and pedestrians, and traditional sunglasses may not adequately address the issue of color recognition, leading to hazardous conditions.
Innovation Solution
A multi-layer imaging system using multiple liquid crystal display (LCD) layers in eyewear or vehicle windshields, which captures and processes multiple images to identify and diminish bright spots, such as sun glare, while emphasizing the target object, thereby improving visibility of traffic signals and other critical features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional sunglasses are used to block sun glare, then the brightness of sun glare is reduced, but the visibility of colors in traffic signals is lost
Solution Approach 1:
The imaging system is divided into multiple functional layers: a first image capture layer that captures the scene with sun glare, and a second image capture layer that captures the scene without sun glare. These segmented layers are processed separately and then combined to produce a final image that eliminates glare while preserving color information.
Solution Approach 2:
The patent introduces an intermediary processing system that acts as a mediator between the captured images and the final output. This intermediary system includes image processing modules that identify bright spots, generate corrected images, and combine multiple images to produce the final glare-free image with preserved color information.
2Reliability
If multiple images are captured and processed to eliminate bright spots, then visibility of target objects is improved, but device complexity increases
Solution Approach 1:
The imaging apparatus integrates multiple functions into a single device: it captures images with and without sun glare, processes these images to identify bright spots, generates corrected images, and combines them into a final output. This multi-functional integration improves reliability while managing device complexity through unified system design.
Solution Approach 2:
The patent employs a nested structure where multiple image processing functions are embedded within each other. The first image processing module identifies bright spots, the second module generates corrected images based on this identification, and the third module combines multiple images. These nested processing stages work hierarchically to achieve reliable target visibility.

AI summary
For multi-layer imaging, an apparatus is disclosed. The apparatus includes a transparent display having multiple liquid crystal display (LCD) layers. The apparatus includes an image capture module that interfaces with a camera to capture multiple images of a target object. The apparatus includes an image processing module that identifies a bright spot in first and second images, identifies the target object in the first and second images proximate to the bright spot, and modifies at least one of first and second images to diminish the bright spot and to emphasize the target object. The apparatus includes an image display module that interfaces with the transparent display member to display the first image with the first LCD layer and display the second image with the second LCD layer after modifying at least one of the first and second images.
