Native Mosaic Image Storage and Display Layout Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing conversion processes between Bayer and Diamond layouts in digital image capture and display devices involve extensive interpolation, leading to reduced image quality and increased processing requirements due to the mismatch between the layouts of image capture, storage, and display devices.
Innovation Solution
Storing images in their native mosaic format and synchronizing the capture, storage, and display layouts to avoid demosaic computations, allowing direct display without interpolation, thereby maintaining higher visual quality and reducing bandwidth and storage needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If demosaic computations are performed to convert between Bayer and Diamond layouts, then images can be displayed on different layout devices, but image quality is reduced and processing requirements increase
Solution Approach 1:
The patent applies preliminary action by pre-converting image data from Bayer layout to Diamond layout immediately after capture, storing it in the target layout before display. This eliminates the need for real-time demosaic computations during display, preserving image quality while enabling compatibility with Diamond layout devices.
Solution Approach 2:
The patent introduces an intermediary conversion process that transforms image data between Bayer and Diamond layouts using a defined mapping relationship. This intermediary step allows seamless compatibility between different layout devices without requiring complex real-time interpolation during display.
2Adaptability or versatility
If demosaic computations are performed to convert between Bayer and Diamond layouts, then images can be displayed on different layout devices, but processing requirements increase
Solution Approach 1:
The conversion from Bayer to Diamond layout is performed as a preliminary action during image capture or preprocessing, rather than during display. This shifts the processing burden to an earlier stage and allows the display device to simply render pre-converted data, significantly reducing real-time processing requirements.
Solution Approach 2:
By performing the layout conversion in advance and storing the converted data, the system eliminates the need for complex real-time demosaic computations during display, reducing processing requirements while maintaining display compatibility.
3Ease of operation
If conventional storage formats are used, then images can be stored and transmitted, but bandwidth and storage needs increase
Solution Approach 1:
The patent changes the storage format parameter from conventional full-resolution RGB to a compressed representation that exploits the relationship between Bayer and Diamond layouts. By storing only the essential data and reconstructing the full image during display, the system reduces storage and bandwidth requirements while maintaining full storage capability.

AI summary
A system includes: an image capture device configured to capture image data from a camera system, the image data being in a first mosaic layout; an image display device configured to display the image data in a second mosaic layout; and a processor configured to receive the image data in the first mosaic layout and to supply the image data in the second mosaic layout to the display without intermediate conversion to a fully collocated image layout.
