Image Data Transmission via Fixation Region Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display technologies face limitations in data transmission bandwidth between image processing devices and display devices, leading to tearing phenomena and compromised high-fidelity display effects due to insufficient data bandwidth, with conventional solutions either compressing image data or transmitting low-resolution images, which adversely affect the display quality.
Innovation Solution
An image data transmission method that identifies a fixation region and a non-fixation region on the display screen, compresses image data for the non-fixation region to a lower resolution, and combines it with high-resolution data from the fixation region, allowing for efficient data transmission while maintaining high-definition display quality at the fixation region.

Engineering Contradiction Analysis
1Quantity of substance
If image data is compressed to reduce data transmission volume, then data transmission bandwidth is improved, but image quality deteriorates
Solution Approach 1:
The display screen is divided into fixation region and non-fixation region. Image data for the fixation region is transmitted at full resolution while image data for the non-fixation region is transmitted at reduced resolution, thereby reducing overall data transmission volume while maintaining high quality in the important fixation region.
Solution Approach 2:
Different resolution qualities are applied to different regions of the display screen. The fixation region receives high-resolution image data to maintain image quality, while the non-fixation region receives low-resolution image data to reduce data transmission volume.
2Manufacturing precision
If full-resolution image data is transmitted to maintain high-fidelity display, then image quality is improved, but data transmission bandwidth is insufficient
Solution Approach 1:
The image data transmission is segmented into two parts: fixation region data at full resolution and non-fixation region data at reduced resolution. This segmentation allows the system to prioritize bandwidth allocation to the fixation region while reducing overall bandwidth requirements.
Solution Approach 2:
High-quality full-resolution image data is transmitted only for the fixation region where visual attention is focused, while lower-quality reduced-resolution data is transmitted for the non-fixation region, optimizing the use of limited data transmission bandwidth.
3Productivity
If conventional compression schemes are used to reduce data volume, then data transmission efficiency is improved, but display fidelity deteriorates
Solution Approach 1:
Instead of uniformly compressing the entire image, the system segments the image into fixation and non-fixation regions, applying different processing strategies to each region to maintain overall display fidelity while improving data transmission efficiency.
Solution Approach 2:
The system applies local quality differentiation by transmitting full-resolution data for the fixation region and reduced-resolution data for the non-fixation region, thereby maintaining display fidelity in the important region while improving overall data transmission efficiency.
