Vehicle Display System with Automatic Text Orientation Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems, such as those using rear-view cameras, often display information like signs and letters in a mirrored fashion, making them difficult for drivers to read, which can distract and reduce driving safety.
Innovation Solution
A display system with a processing unit that recognizes information areas in camera images and processes them to maintain their original orientation while mirroring the rest of the image, ensuring that critical information like signs and letters are displayed legibly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera image is displayed as a mirror image to simulate conventional mirror view, then the driver is accustomed to the rear-view mirror perspective, but the writing on signs and characters becomes unreadable
Solution Approach 1:
The display is segmented into different regions: the background environment is displayed as a mirror image to maintain driver familiarity, while information areas containing signs and characters are extracted and displayed in non-mirrored orientation to ensure readability. This segmentation allows simultaneous satisfaction of both requirements.
Solution Approach 2:
Different parts of the display have different processing characteristics. The general environment background maintains mirror image properties for familiarity, while specific information areas (signs, characters) are processed with non-mirrored orientation for readability. Each region has optimized quality appropriate to its function.
2Loss of information
If the entire image is processed to maintain original orientation for readability, then signs and characters are easily readable, but the driver loses the familiar mirror view perspective
Solution Approach 1:
The image is divided into background regions and information areas. The background is processed as mirror image while information areas are processed in original orientation, allowing both readability and familiarity to coexist in different parts of the display.
Solution Approach 2:
Instead of applying a single transformation to the entire image, the patent inverts the approach by applying mirror transformation only to the background while keeping information areas in their natural orientation, reversing the conventional wisdom that the entire image should be mirrored.
3Loss of information
If manual processing of images is required to ensure readability, then information can be displayed legibly, but the device complexity and operation time increase
Solution Approach 1:
The system automatically detects information areas containing signs and characters and processes them appropriately without requiring manual intervention. The processing unit autonomously identifies which regions need non-mirrored display, reducing operational complexity.
Solution Approach 2:
Manual image processing and manual adjustment are replaced by an automated processing unit that uses algorithms to detect information areas and apply appropriate transformations, substituting mechanical/manual operations with electronic/algorithmic processing.

AI summary
The invention relates to a display system (10) for a vehicle (1), which display system can be used to display an environment (30) around the vehicle (1), with at least one camera (11) for recording an image (20) of the environment (30), and with a display unit (13) on which the image (20) can be at least partially reproduced. According to the invention, the display system (10) has a processing unit (12) which, if the image (20) contains at least one information region (21), automatically identifies the information region (21) and at least partially processes the image (20) to be reproduced on the display unit (13) in such a manner that the information region (21) can be reproduced in the rest of an image (22) on the display unit (13) in a view which is mirror-inverted with respect to the rest of the image (22).
