ISP Reset Controller Isolates Image Data Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing systems face challenges in error detection and handling, particularly in multi-context image processing, where errors in one context can affect all contexts, leading to data loss and system instability.
Innovation Solution
The system employs a reset controller that detects errors in one context of multi-context image processing and resets only that context while maintaining others, ensuring continuous processing of unaffected image data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a reset operation is performed on image data in multi-context processing, then error handling is improved, but other contexts may be affected by the reset operation
Solution Approach 1:
The patent divides the image processing system into multiple independent contexts (first context, second context, etc.), each with its own dedicated memory region. The reset controller can selectively reset only the memory region corresponding to the erroneous context without affecting other contexts. This segmentation allows isolated error handling while preserving data integrity in other processing contexts.
Solution Approach 2:
The patent introduces a reset controller as an intermediary component between the error detection mechanism and the memory reset operation. The reset controller receives error signals, identifies the affected context, and executes targeted reset operations only on the specific memory region associated with that context. This intermediary enables precise error isolation and prevents widespread system disruption.
2Reliability
If all image data is reset when an error is detected, then error handling is simplified, but data loss increases
Solution Approach 1:
The patent implements separate memory regions for different contexts (first context memory, second context memory, etc.). When an error is detected in one context, only the corresponding memory region is reset, while other memory regions retain their data. This segmentation approach minimizes information loss by limiting the reset operation to only the affected context.
Solution Approach 2:
The patent applies local quality by making each context's memory region have independent properties and error-handling characteristics. Each context can be reset independently based on its specific error conditions, allowing selective data recovery while preserving intact data in other contexts. This local化的 error handling strategy reduces overall data loss compared to a global reset approach.
3Reliability
If context isolation is implemented to prevent error propagation, then system stability is improved, but device complexity increases
Solution Approach 1:
The patent segments the memory into distinct regions (first memory region, second memory region, etc.) corresponding to different contexts. Each region can be independently managed and reset. This physical or logical segmentation provides context isolation that prevents error propagation while maintaining a relatively simple implementation through dedicated memory addressing and control mechanisms.
Solution Approach 2:
The reset controller serves as an intermediary that manages context isolation by receiving error signals, identifying the affected context, and executing targeted reset operations. This intermediary component simplifies the overall system architecture by centralizing the error handling logic and avoiding the need for complex distributed error management mechanisms across multiple contexts.

AI summary
Systems and techniques are described herein for processing image data. For instance, an apparatus for processing image data is provided. The apparatus may include an image-signal processor (ISP) configured to process first image data of a data stream and to process second image data of the data stream; and a reset controller configured to, in response to a detected error related to the first image data, reset the first image data in a memory of the ISP while maintaining the second image data in the memory of the ISP.
