Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple viewpoint images are transmitted for ultra-high-resolution multi-viewpoint stereoscopic display, then image quality and stereoscopic effect are improved, but data transmission complexity and bandwidth requirements increase significantly
Solution Approach 1:
The patent segments the multiple viewpoint images into different color component groups (e.g., R1-Y, B2-Y, G3-Y) and processes each group separately through independent encoding pipelines. This segmentation reduces the complexity of transmitting all viewpoint images simultaneously while maintaining ultra-high-resolution quality for each viewpoint.
Solution Approach 2:
The patent introduces an intermediary processing stage that converts multiple viewpoint images into a compressed representation using color component grouping and differential encoding. This intermediary format serves as a bridge between the high-quality source images and the transmission channel, reducing bandwidth requirements while preserving image quality.
2Manufacturing precision
If multiple viewpoint images are transmitted for ultra-high-resolution multi-viewpoint stereoscopic display, then stereoscopic display effect is improved, but transmission bandwidth requirements increase
Solution Approach 1:
The patent merges multiple viewpoint images by grouping their color components (e.g., combining red components from different viewpoints into R1-Y format, blue components into B2-Y format). This merging reduces the total data quantity while preserving the stereoscopic information needed for high-quality multi-viewpoint display.
Solution Approach 2:
The patent changes the parameter representation of the images by transforming from standard RGB format to a differential color component format (R1-Y, B2-Y, G3-Y). This parameter transformation reduces the bandwidth required for transmission while maintaining the ultra-high-resolution quality and stereoscopic effects.
3Ease of manufacture
If conventional encoding methods are used for multi-viewpoint images, then implementation is simple, but image quality and stereoscopic effect are compromised
Solution Approach 1:
The patent introduces dynamic processing in the encoding stage by adaptively grouping color components and applying differential encoding based on the specific characteristics of each viewpoint image. This dynamic approach maintains implementation feasibility while significantly improving image quality and stereoscopic effects compared to static conventional methods.
