Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image and video rendering technologies fail to accurately maintain the original appearance of video content across displays with differing capabilities, leading to noticeable distortions and artifacts due to inadequate handling of metadata.
Innovation Solution
A scalable color management system that employs varying levels of metadata to adjust image processing based on display characteristics, using metadata to predict and maintain the intended appearance of video content across different displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional image processing is used without metadata, then processing speed is maintained, but rendering accuracy and color management precision deteriorate
Solution Approach 1:
The patent segments metadata into multiple levels (Level 1: basic display characteristics, Level 2: content-specific parameters, Level 3: advanced color management data). This allows the system to process only the necessary metadata level for each application scenario, improving rendering accuracy without always increasing full system complexity.
Solution Approach 2:
The system applies partial metadata processing based on availability and requirements. When metadata is present, it processes and applies the relevant parameters; when absent, it uses defaults or makes assumptions. This partial action approach maintains accuracy where possible while avoiding unnecessary processing overhead.
2Manufacturing precision
If metadata is added to improve color management, then rendering fidelity improves, but data processing complexity and computational load increase
Solution Approach 1:
The system dynamically adjusts its processing behavior based on metadata availability. When metadata is present, it applies sophisticated color management algorithms; when absent, it uses simplified processing paths. This dynamic adaptation maintains color management precision when needed while preserving processing efficiency in metadata-absent scenarios.
Solution Approach 2:
The patent changes processing parameters based on metadata levels. Different metadata levels trigger different algorithmic approaches and parameter settings in the color management module, allowing the system to optimize between precision and efficiency by adjusting parameters according to the richness of available metadata.
3Productivity
If default values are used when metadata is absent, then processing speed is maintained, but rendering quality deteriorates
Solution Approach 1:
The system performs preliminary detection to determine whether metadata is available before initiating processing. This preliminary action allows the system to follow different processing paths: full processing when metadata is present, simplified processing when absent. This maintains rendering quality by applying appropriate processing depth based on available information.
4Adaptability or versatility
If multiple metadata levels are implemented, then adaptability to different displays improves, but system complexity increases
Solution Approach 1:
The metadata structure is segmented into hierarchical levels with increasing specificity. Level 1 provides basic display information, Level 2 adds content-specific parameters, and Level 3 includes advanced color management data. This segmentation enables the system to be adaptable to different displays by selectively processing appropriate levels without managing overwhelming complexity.
Solution Approach 2:
The multi-level metadata structure serves multiple functions: it provides basic display characteristics for all content, adds content-specific parameters when available, and includes advanced color management data when needed. This universal structure with optional extensions improves display adaptability while managing complexity through optional depth.
