Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In monitor systems, video signals often require format conversion to match the specific timing format of the display panel, but existing technologies lack efficient methods for handling multiple timing formats, resolutions, and color formats, leading to suboptimal video display quality.
Innovation Solution
A video processing device with a receiver, normalization processor, selector, and image processor is introduced, featuring multiple normalization sub-circuits for format adjustment, such as interpolation, boundary filling, and pixel replication, along with image processing and analysis sub-circuits to generate optimized video images for display, allowing for selection based on user instructions for desired display effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple normalization sub-circuits are used to handle different timing formats and resolutions, then adaptability is improved, but device complexity increases
Solution Approach 1:
The video processing device is divided into multiple independent normalization sub-circuits, each dedicated to handling specific timing formats or resolution requirements. This segmentation allows each sub-circuit to be optimized for its specific function while collectively providing comprehensive format support, resolving the contradiction between adaptability and complexity through functional decomposition
Solution Approach 2:
The multiple normalization sub-circuits are designed with universal interfaces and standardized output formats, allowing them to handle various video formats through a common architecture. Each sub-circuit can process different input formats while producing outputs compatible with the display panel, achieving multi-functionality without proportionally increasing overall system complexity
2Adaptability or versatility
If format conversion is performed to match display panel timing format, then display compatibility is improved, but image quality deteriorates
Solution Approach 1:
The normalization sub-circuits perform format conversion in advance before the video signal reaches the display panel, preparing multiple pre-processed versions of the video signal in different timing formats and resolutions. This preliminary action ensures that the conversion is done optimally before display requirements are finalized, maintaining image quality while achieving compatibility
Solution Approach 2:
The normalization sub-circuits employ advanced parameter change techniques including interpolation algorithms, pixel replication, and boundary handling methods that adjust video signal parameters (timing, resolution, scan rate) while minimizing quality loss. These parameter transformations are designed to preserve image fidelity during format conversion
3Ease of operation
If multiple normalization processing modes are provided, then user selection flexibility is improved, but processing time increases
Solution Approach 1:
Multiple normalization processing modes are executed in parallel as preliminary actions, generating multiple processed video signals simultaneously. The user can then select from pre-computed options without waiting for sequential processing to complete, reducing perceived processing time while maintaining operational flexibility
Solution Approach 2:
The system dynamically selects and activates only the necessary normalization sub-circuits based on real-time display requirements and user preferences. This dynamic approach avoids the overhead of continuously running all processing modes, reducing processing time while preserving user selection flexibility when needed
