Hybrid Mirror Display Viewing Angle Alignment Without Precise Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in adjusting the viewing angles of video displayed on an electronic mirror and the range visually recognizable in a rearview mirror to coincide with each other, particularly due to difficulties in maintaining the relative positional relation between the camera and the rearview mirror.
Innovation Solution
A display apparatus that includes a display for showing images captured by an imaging unit, a half mirror for reflecting the view behind a moving object, and processors that switch between a mirror surface display state and an image display state to adjust the viewing angles so they are approximately the same.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera and rearview mirror are installed with strict mechanical relative relation to maintain accurate viewing angle alignment, then the viewing angle matching between electronic mirror and rearview mirror is improved, but the installation complexity and difficulty increase
Solution Approach 1:
The patent replaces the mechanical alignment system with a software-based viewing angle adjustment system. The processor adjusts the electronic mirror's viewing angle through image processing and display control, eliminating the need for precise mechanical positioning of the camera relative to the rearview mirror. This substitution resolves the contradiction by achieving accurate viewing angle matching through electronic means rather than mechanical constraints.
Solution Approach 2:
The patent changes the viewing angle parameter of the electronic mirror through software control of the display unit. By adjusting display parameters such as image scaling, positioning, and orientation on the screen, the system achieves viewing angle alignment with the rearview mirror without requiring fixed mechanical relationships. This parameter-based adjustment resolves the contradiction between alignment accuracy and installation complexity.
2Ease of manufacture
If the camera is positioned far from the rearview mirror to simplify installation, then the ease of manufacture is improved, but the ability to accurately maintain relative positional relation deteriorates
Solution Approach 1:
The patent replaces the mechanical coupling between camera and rearview mirror with an electronic adjustment system. The processor compensates for any positional deviations by adjusting the displayed image parameters, allowing the camera to be installed independently without strict positional constraints. This substitution enables easy installation while maintaining reliable viewing angle alignment through software compensation.
3Ease of operation
If the viewing angle of the electronic mirror is adjusted to match the rearview mirror, then the usability is improved, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The patent replaces mechanical adjustment mechanisms with software-based viewing angle control. The processor adjusts the electronic mirror's display parameters to match the rearview mirror's viewing angle, eliminating the need for physical adjustment mechanisms. This substitution improves usability while avoiding the complexity of additional mechanical components.
Solution Approach 2:
The patent makes the display unit serve multiple functions: displaying the electronic mirror image and simultaneously adjusting its viewing angle to match the rearview mirror. The processor integrates the viewing angle adjustment function within the existing display system, avoiding the need for separate adjustment mechanisms. This multi-functionality approach improves usability without increasing device complexity.

AI summary
A display apparatus includes a display that displays an image captured by an imaging unit that captures an image of a view behind a moving object, a half mirror that reflects the view behind the moving object and disposed on an anterior surface of the display, one or more memories storing instructions, and one or more processors executing the instructions to switch a state between a mirror surface display state where a reflection image on the half mirror is displayed and an image display state where the image is displayed on the display and perform adjustment so that a viewing angle of the image displayed on the display and a viewing angle reflected by the half mirror are approximately the same as each other while switching the state between the mirror surface display state and the image display state.
