YUV Display Frame Processing for Faster Motion Quality Enhancement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies require longer processing times due to high load of correction calculations when improving moving picture performance by doubling the frame rate.
Innovation Solution
A display device that divides each frame into two sub-frames, applying luminance emphasis and blur processing separately on Y luminance data, and coupling it with U and V color difference data to improve moving picture quality without increasing processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If luminance emphasis processing and blur processing are applied to improve moving picture quality at doubled frame rate, then display quality is improved, but processing time becomes longer
Solution Approach 1:
The patent segments the processing workload by applying luminance emphasis and blur processing only to the Y luminance component rather than processing all color components. This segmentation of the processing scope reduces the overall computational load while maintaining the quality improvement benefits for the most visually important component (luminance), thereby resolving the contradiction between display quality and processing time.
Solution Approach 2:
The patent applies different processing treatments to different components of the image data selectively. Specifically, luminance emphasis and blur processing are applied locally to the Y component, while the U and V color difference components are processed separately or not at all. This local quality approach optimizes processing efficiency by focusing computational resources only where they provide the most significant visual improvement.
2Manufacturing precision
If correction calculation load is increased to improve moving picture performance, then display quality improves, but processing time increases
Solution Approach 1:
The patent extracts the essential processing requirement from the full color space and applies it only to the Y luminance component. By taking out the processing operation from the complete image data and restricting it to only the necessary luminance portion, the system maintains moving picture performance improvement while significantly reducing the correction calculation load and processing time.
Data Source
AI summary
A main calculation unit generates emphasized Y luminance data by performing luminance emphasis processing on only Y luminance data included in YUV data representing an image of one frame. Further, the main calculation unit generates blurred Y luminance data by performing luminance blur processing on only the Y luminance data. In this way, it is possible to perform processing for improving the display quality of a moving picture in a shorter time period.
