Parallel Image Transformation Pipelines for Field Sequential Color Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Field sequential color (FSC) display devices face challenges in reducing visual latency and energy consumption due to the need for separate full rendering of each color field, which increases processing time and power consumption, and existing post-rendering transformation methods are not well-suited for FSC devices that receive color data in successive fields.
Innovation Solution
A post-rendering image transformation module with multiple image transformation pipelines applies 2D transformations to generate transformed pixel color data for each color component, allowing for sequential generation and output of color component fields, reducing processing overhead and energy demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate full rendering is performed for each color field using CPU or GPU, then color field processing can be completed, but power consumption and latency increase
Solution Approach 1:
The patent segments the image transformation process into multiple parallel pipelines, where each pipeline processes a different color component (red, green, blue) independently. This allows the system to process all color fields simultaneously rather than sequentially, maintaining productivity while reducing power consumption by avoiding repeated full renderings
Solution Approach 2:
The patent performs preliminary rendering of the complete image once, then applies post-rendering transformations to generate individual color fields. This preliminary action eliminates the need for separate full renderings for each color field, significantly reducing power consumption while maintaining processing throughput
2Productivity
If separate full rendering is performed for each color field using CPU or GPU, then color field processing can be completed, but processing time (latency) increases
Solution Approach 1:
The patent divides the transformation process into segmented parallel pipelines that operate simultaneously on different color components. This segmentation enables concurrent processing of red, green, and blue fields, reducing the total time required compared to sequential processing while maintaining high productivity
Solution Approach 2:
The patent implements continuous transformation processing where multiple pipelines operate continuously and in parallel on different color fields. This continuous action eliminates idle time between processing steps and maintains steady throughput while reducing overall latency
3Adaptability or versatility
If buffering a full RGB field for output as successive red, green, and blue fields is done, then FSC display compatibility is achieved, but output buffer size increases latency and/or power consumption
Solution Approach 1:
The patent segments the transformation output into separate color component fields that are generated on-demand and processed in parallel. This segmentation allows the system to output successive red, green, and blue fields without buffering the entire RGB field, thereby maintaining FSC compatibility while reducing latency
Solution Approach 2:
The patent performs preliminary transformation of color fields in parallel as they are generated, rather than buffering complete RGB fields for later processing. This preliminary action eliminates the need for large output buffers and reduces both latency and power consumption while maintaining FSC display compatibility
4Adaptability or versatility
If buffering a full RGB field for output as successive red, green, and blue fields is done, then FSC display compatibility is achieved, but power consumption increases
Solution Approach 1:
The patent segments the processing into parallel color component pipelines that operate independently and simultaneously. This segmentation eliminates the need to buffer full RGB fields, reducing memory bandwidth requirements and power consumption while maintaining FSC display compatibility through efficient color field generation
Solution Approach 2:
The patent implements continuous parallel processing of color fields as they are generated and transformed. This continuous action eliminates idle buffering periods and maintains steady processing throughput, reducing overall power consumption while ensuring FSC display compatibility through efficient color field output
