Solution Overview

Problem

Virtual reality systems experience image delay, leading to video blur and poor display quality due to the limitations of increasing screen refresh rates, which are constrained by hardware rendering capabilities, and the frame rate up-conversion image processing method based on motion compensation fails when motion trajectories between frames cannot be estimated, causing display defects.

Innovation Solution

A video processing method that determines the motion state of a display apparatus using acceleration and angular velocity data, adjusting the frame rate up-conversion image processing method based on motion compensation to either continue or stop processing, thereby reducing data processing burden and avoiding display defects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If the frame rate up-conversion image processing method based on motion compensation is used to process video, then video quality is improved by reducing blur, but data processing burden increases and display defects occur in complex motion states

Engineering Contradiction:
Improvevideo qualityVSAvoiddata processing burden
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent dynamically adjusts the image processing method based on real-time motion state detection. When complex motion is detected (exceeding threshold), the system switches from frame rate up-conversion with motion compensation to a simpler processing method, avoiding excessive data processing burden while maintaining video quality in normal motion states

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the processing parameter (frame rate up-conversion enablement) based on motion state parameters. By monitoring motion thresholds and adjusting whether to apply motion compensation processing, the system optimizes the balance between video quality and data processing burden according to actual motion conditions

Inventive Principle:
Principle #35Parameter changes

2Manufacturing precision

If the screen refresh rate is increased to reduce image delay, then display quality improves, but hardware rendering capabilities are exceeded

Engineering Contradiction:
Improvedisplay qualityVSAvoidhardware rendering capability
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent changes the effective frame rate parameter through processing rather than hardware refresh rate. By applying frame rate up-conversion software processing, the system achieves higher effective display quality without exceeding hardware rendering capabilities, as the processing generates additional frames computationally rather than requiring higher hardware refresh rates

Inventive Principle:
Principle #35Parameter changes

3Manufacturing precision

If motion compensation processing is applied in all motion states, then video blur is reduced, but display defects occur in complex motion states where motion trajectories cannot be estimated

Engineering Contradiction:
Improvevideo qualityVSAvoiddisplay defect avoidance
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent implements feedback control by continuously monitoring motion state parameters and comparing them against thresholds. When complex motion exceeding the threshold is detected, the system feedback-adjusts by disabling motion compensation processing, preventing display defects caused by unestimable motion trajectories while maintaining quality in normal motion states

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent dynamically switches between different processing modes based on real-time motion state assessment. In normal motion states, motion compensation is applied to reduce blur; in complex motion states, the system switches to a more robust processing mode that avoids assumptions about motion trajectories, thereby maintaining reliability across all motion conditions

Inventive Principle:
Principle #15Dynamics

AI summary

A video processing method includes: receiving motion information of a display apparatus; determining, according to the motion information of the display apparatus and a motion threshold of the display apparatus, whether a motion state of the display apparatus affects the effect of the display apparatus using a frame rate up-conversion image processing method based on motion compensation to process a video that is to be displayed by the display apparatus; if yes, stopping using the frame rate up-conversion image processing method based on motion compensation to process the video that is to be displayed by the display apparatus; if no, continuing to use the frame rate up-conversion image processing method based on motion compensation to process the video that is to be displayed by the display apparatus.
