Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in converting pixel arrays from a stripe configuration to a square configuration while maintaining image quality, particularly in three-dimensional display systems, leading to degradation in image resolution and reproducibility.
Innovation Solution
A display control apparatus and method that includes a conversion and synthesis unit to associate view point image sub-pixels with three-dimensional display sub-pixels, deciding sub-pixel values before conversion, and generating new sub-pixels to maintain image quality, allowing conversion from stripe to square arrays with doubled horizontal resolution and halved vertical resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If pixels in stripe array are converted into pixels in square array, then the display can utilize square pixel configurations with four sub-pixels (R, G, B, W), but a shift of arrangements between pixels in stripe array and pixels in square array is generated causing image quality degradation
Solution Approach 1:
The correspondence relationship between stripe array pixels and square array pixels is determined in advance through the correspondence determination unit. This preliminary mapping is established before the actual conversion process, allowing the system to pre-calculate which stripe pixels should contribute to each square pixel to maintain image quality during the transformation.
Solution Approach 2:
The conversion process is segmented into distinct functional units: a correspondence determination unit that establishes mapping relationships, a value determination unit that calculates sub-pixel values based on the mapping, and a pixel generation unit that creates the final square array pixels. This segmentation allows each unit to optimize its specific function while working together to preserve overall image quality.
2Manufacturing precision
If resolution in lateral direction is set to be two-folds for square array pixels, then color mixture between sub-pixels is suppressed, but conversion from stripe array requires sophisticated correspondence mapping to maintain image quality
Solution Approach 1:
The correspondence determination unit establishes localized mapping relationships between specific stripe pixels and specific square pixels. Each square pixel's correspondence is determined independently based on its position and the required color composition, allowing precise control over color accuracy at each local position rather than applying a uniform conversion rule across the entire image.
Solution Approach 2:
The correspondence determination unit acts as an intermediary between the stripe array input and square array output. It translates the arrangement differences between the two pixel types by calculating the appropriate mapping relationships, thereby mediating the conversion process and reducing the apparent complexity for the overall system.
3Quantity of substance
If multiple stripe pixels are associated with single square pixel, then sufficient sub-pixel values can be obtained for conversion, but image quality degradation occurs without proper correspondence control
Solution Approach 1:
The correspondence determination unit pre-establishes which multiple stripe pixels should be associated with each square pixel before the conversion occurs. This preliminary grouping ensures that the correct combination of stripe pixels is selected to provide sufficient sub-pixel data for each square pixel while maintaining image quality through controlled association rather than random or uniform sampling.
