Color Filter Array Resolution Enhancement via Pixel Pattern Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image display devices using the color filter method often experience a decrease in display image resolution due to the arrangement of red, green, and blue pixels, which limits the quality of full color image rendering.
Innovation Solution
An image processing device and method that separates red, green, and blue image data, sets multiple pixel combination patterns for filter processing, and combines these processed data to generate full color images, incorporating peripheral pixel information to enhance image quality by using a filter processor and display image generator with a color image separator and filter controller.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If three pixels (red, green, and blue) are arranged to constitute one full color pixel using the color filter method, then full color image display is achieved, but the resolution of the display image decreases
Solution Approach 1:
The patent segments the pixel arrangement into multiple independent patterns (first, second, third, and fourth patterns) where each pattern contains red, green, and blue pixels in different spatial configurations. This segmentation allows the system to process and combine multiple lower-resolution patterns to achieve higher effective resolution while maintaining full color capability.
Solution Approach 2:
The patent merges multiple pixel patterns of the same color (e.g., multiple red pixel patterns, multiple green pixel patterns, multiple blue pixel patterns) through superimposition and combination. By combining these segmented patterns, the system achieves higher effective resolution while preserving complete color information, thus resolving the contradiction between color completeness and display resolution.
2Manufacturing precision
If multiple pixel combination patterns are used for filter processing, then image quality improves by reflecting more peripheral pixel information, but device complexity increases
Solution Approach 1:
The patent performs preliminary segmentation of the image into multiple pixel patterns (first, second, third, fourth patterns) with different spatial arrangements before final combination. This preliminary action organizes the complex processing task into manageable segments, making it easier to handle the complexity while improving image quality through comprehensive use of peripheral pixel information.
Solution Approach 2:
The patent creates multiple copies of pixel patterns with different spatial configurations (first pattern, second pattern, third pattern, fourth pattern) and processes each copy independently. By copying and processing multiple patterns, the system captures more peripheral information to enhance image quality while distributing the computational complexity across parallel processing of identical structural copies.

AI summary
An image display device includes a color image separator, a filter controller, a filter processor, a display image generator, and a display. The color image separator separates red image data, green image data, and blue image data from input image data. The filter controller sets a plurality of pixel combination patterns for performing filter processing on the red image data, green image data, and blue image data. The filter processor performs filter processing for each pixel combination pattern on the red image data, green image data, and blue image data. The display image generator combines the filter-processed red image data, green image data, and blue image data, for each filter processing by the same pixel combination pattern, to generate a plurality of full color images. The display includes color filters.
