Display Signal Input Device for Ultra-High Resolution Stitching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image processing systems cannot effectively drive ultra-high resolution display devices, such as 8k × 4k UHDs, as they lack the capability to stitch together multiple sub-images into a cohesive image, given the limitations of existing image processing chips and signal transmission lines.
Innovation Solution
A display signal input device with sub-image receiving modules and an image stitching module that buffers, sequences, and synthesizes sub-images to ensure proper alignment and edge matching, allowing for efficient output of display signals to corresponding display areas, thereby enabling the driving of ultra-high resolution displays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sub-images are transmitted separately to drive ultra-high resolution displays, then the display resolution can be increased to 8k × 4k, but the image processing complexity and device complexity increase significantly
Solution Approach 1:
The patent divides the ultra-high resolution image into multiple sub-images (e.g., four 4k × 2k sub-images for an 8k × 4k display). Each sub-image is processed and transmitted separately through existing capability-limited channels, then stitched together at the display device to form the complete high-resolution image. This segmentation allows the system to achieve beyond-the-capability resolution without requiring any single component to handle the full ultra-high resolution load.
Solution Approach 2:
The patent implements a nested structure where multiple sub-images (smaller units) are combined to form the complete ultra-high resolution image (larger unit). The display device contains stitching logic that integrates the separate sub-image streams into a cohesive final image, creating a nested relationship between the processed sub-images and the final displayed image.
2Measurement precision
If multiple image processing chips and signal transmission lines are used to transmit multiple sub-images, then ultra-high resolution display can be achieved, but the system complexity and number of components increase
Solution Approach 1:
The system segments the image processing task across multiple chips and transmission lines, with each chip handling a specific sub-image. This distribution allows the use of existing lower-capability components to collectively achieve higher resolution than any single component could provide alone.
Solution Approach 2:
The patent merges multiple separate processing paths (each handling a sub-image) into a unified final image through the stitching module. The display device combines the outputs from multiple chips and transmission lines into a single coherent ultra-high resolution image, reducing the need for a single complex high-capability processing unit.
3Measurement precision
If sub-images are stitched together to form high-resolution images, then the processing capability exceeds that of general image processing chips, but the stitching process complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-processing each sub-image separately using standard image processing techniques before stitching. Each sub-image undergoes complete processing (color correction, sharpening, etc.) independently, so that when they are stitched together, minimal additional processing is needed to achieve the final high-resolution image.
Solution Approach 2:
The stitching module acts as an intermediary that bridges the gap between separately processed sub-images and the final high-resolution image. It provides the coordination and integration logic needed to combine the sub-images, handling the complexity of alignment and merging without requiring the entire system to be redesigned for ultra-high resolution processing.
