Image Processing Apparatus Cutout Region Hand Shake Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic type hand shake correcting systems in imaging devices consume excessive power and processing resources due to unnecessary image processing across the entire valid pixel region, limiting frame rates and increasing power consumption.
Innovation Solution
An image processing apparatus that determines a cutout region based on motion information and performs image processing only within this effective pixel region, reducing unnecessary processing and power consumption by separating former and latter stage processing within the sensor module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image processing is performed across the entire valid pixel region for hand shake correction, then hand shake correction effectiveness is improved, but power consumption and processing load increase excessively
Solution Approach 1:
The patent extracts only the effective pixel region that actually contains image information from the entire valid pixel region. By performing hand shake correction processing only on this extracted effective region rather than the full sensor output, the processing load and power consumption are significantly reduced while maintaining correction effectiveness for the actual image content.
Solution Approach 2:
The patent applies different processing strategies to different regions of the sensor output. The effective pixel region receives full hand shake correction processing, while the invalid region (containing no image information) is excluded from processing. This localized approach optimizes resource allocation by applying computational effort only where needed.
2Reliability
If image processing is performed across the entire valid pixel region, then hand shake correction completeness is improved, but frame rate is limited due to processing load
Solution Approach 1:
The patent extracts and processes only the effective pixel region containing actual image data, excluding invalid regions from the processing pipeline. This reduction in processing volume enables higher frame rates by decreasing the computational burden while ensuring complete hand shake correction for all pixels that actually contribute to the final image.
3Manufacturing precision
If full pixel region processing is performed, then processing thoroughness is improved, but unnecessary processing of invalid regions increases power consumption
Solution Approach 1:
The patent extracts the effective pixel region from the full sensor output and performs processing only on this extracted subset. This eliminates energy waste associated with processing invalid regions that contain no image information, while maintaining thorough processing of all relevant pixels.
Solution Approach 2:
The patent implements region-specific processing where the effective pixel region receives complete hand shake correction processing while invalid regions are excluded. This local quality approach ensures processing thoroughness is applied only where it matters, eliminating unnecessary energy consumption.
