Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional LCD display apparatuses use fixed weights to adjust display parameters, which may not effectively smooth fast scene changes between frames, leading to suboptimal viewing experience.
Innovation Solution
A method and apparatus that dynamically adjust weights based on scene change values to calculate display parameters for the current frame, using a scene change detection unit, weight unit, parameter generating unit, and calculating unit to adapt to both fast-varying and slow-varying scene changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed weights are used to calculate display parameters, then the implementation is simple, but the frame smoothness during fast scene changes deteriorates
Solution Approach 1:
The patent applies the dynamics principle by transforming the static fixed weight system into a dynamic adaptive weight system. The weight assignment unit dynamically adjusts weights based on scene change detection, allowing the system to adapt to varying scene conditions. This resolves the contradiction by maintaining implementation simplicity through automated dynamic adjustment rather than complex manual tuning.
Solution Approach 2:
The patent changes the parameter of weight values from fixed to variable based on scene change magnitude. By detecting scene changes and adjusting weights accordingly (higher weights for current frame during fast changes, higher weights for previous frame during slow changes), the system improves frame smoothness while maintaining simple implementation through parameter adaptation.
2Device complexity
If fixed weights are used for display parameter adjustment, then the device complexity is low, but the adaptability to different scene changes deteriorates
Solution Approach 1:
The patent implements self-service by enabling the system to automatically detect scene changes and adjust weights without external intervention. The weight assignment unit autonomously adapts to different scene conditions, maintaining low device complexity while significantly improving scene change adaptability through self-adjustment mechanisms.
Solution Approach 2:
The patent incorporates feedback by using scene change detection results to inform weight assignment decisions. The system continuously monitors scene changes and adjusts weights based on this feedback, creating a closed-loop control system that enhances adaptability while keeping device complexity manageable through automated feedback processing.
3Reliability
If dynamic weights are used to compensate scene changes, then the frame smoothness improves, but the computational complexity increases
Solution Approach 1:
The patent applies partial action by focusing computational resources only on detecting scene changes and adjusting weights, rather than completely reprocessing all frame parameters. This selective approach improves frame smoothness through targeted weight adjustment while limiting computational complexity increase to only the necessary scene change detection and weight assignment operations.
