Video Display Image Distance Adjustment for Interframe Difference Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing video display technologies often result in poor visual effects due to phenomena like stuck screens, lag, judder, and trailing, caused by large interframe differences between adjacent video frames, leading to uncomfortable user experiences.
Innovation Solution
A method and apparatus that acquire interframe differences between adjacent video frames and adjust the display image distance of video frames accordingly, allowing the display device to render the frames with optimized image distances to match the visual sensitivity of the viewer, thereby improving the visual effect and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video frames are displayed with fixed image distance, then display device complexity is reduced, but visual effect deteriorates due to stuck screen, lag, judder, and trailing caused by large interframe differences
Solution Approach 1:
The patent applies dynamics by making the display image distance adjustable rather than fixed. The system dynamically calculates interframe differences and adjusts the image distance of specific video frames based on the degree of change, allowing the display system to adapt to different video content characteristics and eliminate visual defects like stuck screen and lag.
Solution Approach 2:
The patent applies local quality by adjusting the image distance of specific portions of video frames rather than the entire frame uniformly. The system identifies regions with large interframe differences and applies different image distances to different regions, optimizing the visual effect locally while maintaining overall display quality.
2Reliability
If display image distance is adjusted for all video frames, then visual effect improves, but processing time increases due to calculation of interframe differences
Solution Approach 1:
The patent applies partial action by calculating interframe differences and adjusting image distances only for specific video frames or regions where large differences are detected, rather than processing all frames uniformly. This selective approach reduces unnecessary processing time while maintaining visual quality improvements where needed.
Solution Approach 2:
The patent applies parameter changes by modifying the display image distance parameter based on calculated interframe differences. The system changes the image distance parameter dynamically for specific frames, allowing optimization of visual effects without requiring complete reprocessing of the entire video stream.
3Ease of operation
If standard video display is used, then ease of operation is maintained, but user experience deteriorates due to discomfort from large interframe differences
Solution Approach 1:
The patent applies self-service by implementing automatic detection and adjustment of interframe differences without requiring user intervention. The system autonomously calculates differences between adjacent frames and adjusts image distances automatically, maintaining ease of operation while eliminating user discomfort caused by visual defects.
Solution Approach 2:
The patent applies feedback by continuously monitoring interframe differences and using this information to adjust display parameters in real-time. The system uses the calculated differences as feedback to modify the image distance, creating a closed-loop control system that adapts to video content and eliminates visual discomfort automatically.

AI summary
Various video display control methods and apparatuses and various display devices are provided. A method comprises: acquiring interframe differences between every two adjacent frames in at least two adjacent video frames in sequence of a video, adjusting a local display image distance of at least one video frame in the at least two video frames according to respective interframe differences, and controlling the display device to display a local of the at least one video frame at least according to the local adjusted display image distance of the at least one video frame. A visual effect and user experience can thereby be improved.
