Screen Splicing System Frame Interpolation for Display Smoothness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing screen splicing systems suffer from poor display smoothness, leading to image dithering and blurring due to lower frame rates of video sources, which negatively impact user viewing experiences.
Innovation Solution
A screen splicing system that includes a video acquisition subsystem, a smooth displaying subsystem, and a screen splicing subsystem, where the smooth displaying subsystem performs image processing by interpolating and down-sampling video frames to generate smoother images, which are then cut and transmitted to the screen splicing subsystem for improved display smoothness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video frames are processed without interpolation, then device complexity is reduced, but display smoothness deteriorates
Solution Approach 1:
The patent applies preliminary action by performing frame interpolation before video frames are displayed. The smooth displaying subsystem generates intermediate frames in advance to bridge the gap between low frame rate video sources and high frame rate display requirements, thereby improving display smoothness without requiring complex real-time processing during playback
2Reliability
If frame rate is increased through interpolation, then display smoothness is improved, but processing time increases
Solution Approach 1:
The patent uses copying by creating interpolated frame copies between original video frames. Instead of completely generating new visual information, the system creates intermediate copies that approximate the motion between frames, reducing the computational time required compared to full frame generation while still improving display smoothness
3Manufacturing precision
If video processing is performed without smooth displaying subsystem, then device complexity is reduced, but image quality deteriorates
Solution Approach 1:
The patent introduces an intermediary smooth displaying subsystem between the video acquisition subsystem and the screen splicing subsystem. This intermediary component performs frame interpolation and processing, thereby improving image quality by reducing dithering and blurring effects without requiring the other subsystems to be more complex
