Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
On display apparatuses that show a camera picture and a mirror image, the object and its mirror image may not match in size, leading to unnatural superimposition of overlay images.
Innovation Solution
A display apparatus comprising a half mirror, a camera, and a display with overlay image generation and correction processing units to ensure the overlay image is appropriately sized and positioned for the mirror image, using hardware information to correct discrepancies in size and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If an overlay image is generated based on camera picture without correction, then the generation process is simple, but the overlay image does not match the mirror image in size and position resulting in unnatural superimposition
Solution Approach 1:
The patent applies preliminary action by pre-calculating and storing correction values for overlay image size and position based on mirror image characteristics before actual superimposition. The correction processing unit uses these pre-computed values to adjust the overlay image, ensuring precise matching without complex real-time calculations during display.
Solution Approach 2:
The patent replaces complex mechanical adjustment mechanisms with computational methods. Instead of physically adjusting overlay image parameters through mechanical means, the system uses correction processing units to calculate and apply digital corrections to size and position, achieving precise matching through software-based transformations.
2Reliability
If the overlay image size and position are adjusted to match the mirror image, then natural superimposition is achieved, but additional processing steps are required
Solution Approach 1:
The system performs preliminary calculations to determine the appropriate size and position of overlay images based on mirror image characteristics before superimposition. By pre-computing correction values and storing them for later use, the system ensures accurate matching while reducing the processing burden during actual display operations.
Solution Approach 2:
The correction processing unit automatically adjusts overlay image parameters based on stored correction values without requiring manual intervention. The system self-corrects size and position discrepancies between overlay images and mirror images, maintaining high accuracy while operating autonomously.
