Display Device Image Data Verification Encoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for checking the correctness of image data representation on display devices, particularly in safety-critical areas, are cumbersome and require separate transmission of image descriptions, which is inefficient and can distract operators.
Innovation Solution
Integrating the image description into the image data representation on the display device, allowing it to be transmitted and checked simultaneously, with optional encoding to make it invisible to operators and secure against falsification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image description is transmitted separately to the display device and test device, then the verification can be performed, but the technical effort and complexity increase
Solution Approach 1:
The patent merges the image description and image data into a single transmission stream by integrating the image description directly into the image data representation on the display device. This eliminates the need for separate transmission paths and reduces system complexity while maintaining verification capability.
Solution Approach 2:
The display device is designed to serve multiple functions: it displays the image data for operators while simultaneously embedding the image description for verification purposes. This multi-functionality reduces the need for separate dedicated transmission channels.
2Productivity
If the image description is displayed visibly on the display device, then it can be transmitted integrated, but operators may be distracted from relevant information
Solution Approach 1:
The patent uses color deviation of pixels to encode the image description within the displayed image. By subtly altering pixel colors in predetermined areas, the image description is transmitted in a way that is imperceptible to operators but detectable by verification systems, thus maintaining operator concentration while enabling efficient verification.
Solution Approach 2:
The image description is embedded in a different dimension (color space) rather than being displayed as separate visual information. This allows the verification data to coexist with the operational display without competing for the operator's visual attention.
3Reliability
If checksum verification is used, then data integrity can be checked, but additional verification steps are required
Solution Approach 1:
The verification data (image description) is merged into the image data transmission stream, allowing checksum verification to be performed on the integrated data stream rather than requiring separate verification steps for the image description and image data.

AI summary
The invention relates to a display device (3) and a method for checking the accuracy of a representation of image data on a display means (9), in which the representation of image data (10) is generated from an image description (7) and displayed, and the accuracy of the representation of the image data (10) is checked based on the image description (7). According to the invention, in order to simplify the transmission of the image description (7), the image description (7) is integrated into the representation of the image data (10) and is read out from the representation of the image data (10) for checking.
