Engineering Contradiction Analysis
1Productivity
If multiple regions of interest are analyzed simultaneously from video images, then the information extraction capability is improved, but the processing complexity and resource consumption increase
Solution Approach 1:
The patent divides the video image processing into multiple independent region of interest (ROI) streams, where each ROI is extracted and processed separately. This segmentation allows parallel processing of multiple regions without increasing overall system complexity, as each ROI can be handled independently through dedicated processing pipelines.
Solution Approach 2:
The patent introduces a new dimension of processing by creating multiple ROI video streams from a single video input, effectively transforming the processing architecture from sequential single-region analysis to simultaneous multi-region analysis through stream multiplication.
2Productivity
If multiple regions of interest are analyzed simultaneously from video images, then the information extraction capability is improved, but the processor resource consumption increases
Solution Approach 1:
By segmenting the video stream into multiple ROI-specific streams, the patent enables selective processing where only relevant regions are analyzed in detail while other areas are processed at lower resolution or skipped entirely, reducing overall processor resource consumption.
Solution Approach 2:
The patent applies different processing qualities to different regions of interest, allowing high-resolution analysis only where necessary while using lower resolution or simplified processing for other regions, thereby optimizing processor resource allocation across multiple simultaneous analyses.
3Productivity
If multiple regions of interest are analyzed simultaneously from video images, then the information extraction capability is improved, but the power consumption increases
Solution Approach 1:
The patent segments the video processing into multiple independent ROI streams, enabling the system to activate only the processing pipelines needed for currently relevant regions, thereby reducing power consumption compared to processing the entire video frame at full resolution continuously.
Solution Approach 2:
The patent implements partial processing by analyzing only the necessary portions of the video stream (specific ROIs) rather than processing the entire video frame, allowing the system to achieve sufficient information extraction with reduced computational effort and lower power consumption.

AI summary
An interface (402) to a video imaging device (490) that generates captured frames of a video image (100) is described. The interface includes control registers (430) that store at least two sets of stream parameters (401) corresponding to at least two regions of interest (ROIs) and a function (410) that generates at least two corresponding ROI video streams (460) that are derived from the captured frames as essentially simultaneous output signals using the at least two sets of stream parameters. In some embodiments a new selection value (436) is determined from a current selection value and a derivative parameter stored as a portion of a set of stream parameters. In these embodiments, the generating of the at least two corresponding ROI video streams as essentially simultaneous output signals includes using the new selection value.
