Electronic Mirror Display System with Convex Reflection Mirror
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic mirror systems fail to provide a sense of solidity to drivers viewing displayed images, leading to increased focus adjustment and time required for focusing, especially for aged or far-sighted individuals.
Innovation Solution
A display system comprising a display surface and a display mirror that reflects only a partial area of the displayed image, with the position of the reflection image changing as the viewer's point of view moves, reducing the distance difference between focusing on the road and the displayed image, and incorporating a camera to capture rear or side views for display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a liquid crystal display is used to display rear or side view images, then the driver can view the captured images, but the driver does not acquire a sense of solidity and requires more focus adjustment time
Solution Approach 1:
A convex mirror is introduced as an intermediary between the liquid crystal display and the driver's eye. The mirror reflects the displayed image and creates a virtual image that appears to be located at a different position, reducing the focus adjustment time by making the virtual image distance closer to the road distance.
Solution Approach 2:
The system transitions from direct 2D display viewing to indirect viewing through a convex mirror, adding a dimensional transformation that creates a virtual image space. This dimensional change allows the virtual image to be positioned such that the distance difference between viewing the road and viewing the image is reduced.
2Ease of operation
If the display device is disposed inside the vehicle at a position allowing easy viewing, then the driver can access the image, but the image lacks solidity and depth perception
Solution Approach 1:
The convex mirror serves as a mediator that transforms the flat 2D image into a virtual image with apparent depth and spatial positioning. This intermediary device provides both ease of viewing (maintaining accessibility) and image solidity (through the virtual image effect that simulates three-dimensional space).
3Adaptability or versatility
If a conventional electronic mirror system is used, then the captured image can be displayed, but aged or far-sighted drivers experience increased focus adjustment time
Solution Approach 1:
The convex mirror creates a virtual image positioned such that the optical path distance from the driver's eye to the virtual image is made equivalent to or closer than the distance to the road. This equipotential positioning reduces focus adjustment time for aged or far-sighted drivers by eliminating the need to switch between near and far focal points.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration reduces the amount of focus adjustment and shortens the time required for focusing, providing a sense of solidity and depth to the viewed image, even for drivers with vision difficulties, by presenting a high-definition image that moves with the vehicle.
Implementation Method 1
The display mirror is configured to reflect, as a reflection image, only a partial area in the image displayed on the display surface

AI summary
A display system includes a display surface and a display mirror. The display surface is configured to display image P1 based on a captured image. The display mirror is configured to reflect, as reflection image P2, only a partial area in the image displayed on the display surface. The display system is configured so that a position of reflection image P2 changes as a point of view of a subject viewing the display mirror moves.
