Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OSD bits are not very accurate, leading to issues in image processing due to block-based design, resulting in unnatural discontinuities and missing or redundant user interface elements.
Innovation Solution
An image processor generates a refined OSD pattern by blending an initial OSD pattern with an input image and an intermediate layer, using pixel-wise accuracy to identify protection regions and perform image processing on remaining regions, ensuring precise integration of OSD information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If block-based OSD bits are used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent segments the image into multiple blocks and processes each block separately to identify OSD elements. By dividing the image processing task into block-level operations, the system achieves pixel-wise accuracy within each block while maintaining overall system efficiency. This segmentation allows precise OSD detection without requiring complex global processing.
Solution Approach 2:
The patent transitions from traditional block-based OSD bits to a pixel-wise OSD map representation. This dimensional change from block-level to pixel-level precision enables accurate identification of OSD elements while maintaining computational efficiency through the structured block processing approach.
2Productivity
If block sampling is used, then processing speed is improved, but measurement precision deteriorates
Solution Approach 1:
The patent divides the image into blocks and processes each block independently to generate an OSD map at pixel level. This segmentation enables parallel processing of multiple blocks, maintaining high processing speed while achieving precise OSD element detection through pixel-wise analysis within each block.
Solution Approach 2:
The patent applies block-based processing as a preliminary step followed by pixel-wise refinement within identified regions. This partial application of block sampling maintains processing efficiency while excessive action (pixel-level detail) is applied only where needed for accurate OSD element identification.
3Measurement precision
If pixel-wise accuracy is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent implements pixel-wise accuracy by segmenting the image into blocks and processing each block separately. This segmentation reduces the overall computational complexity by breaking down the pixel-wise processing task into manageable block-level operations, making high-precision OSD detection feasible.
Solution Approach 2:
The patent creates a pixel-wise OSD map that adds a new dimension of precision to the image processing pipeline. This OSD map layer provides pixel-level accuracy information without significantly increasing the base processing complexity, as it operates as an additional processing layer rather than fundamentally changing the core processing architecture.

AI summary
An operation method performed by an image processor is provided, including the following operations of receiving a mixed image including an input image and a first on-screen-display (OSD) pattern and generating a second OSD pattern, different from the first OSD pattern, based on the mixed image. The second OSD pattern encompasses protection regions of the input image, and the protection regions are in close proximity of the first OSD pattern. The method further includes operations of performing image processing to remaining regions, different from the protection regions, of the input image and generating an output image. The output image includes the second OSD pattern and the remaining regions of the input image, being performed by the image processing.
