Image Processing Device Cropped Subject Blur Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When capturing images of moving subjects, cropping the image can result in blurring that cannot be adequately removed by existing deblurring processes.
Innovation Solution
An image processing device that determines the composition and region of interest in an image based on a predetermined rule, calculates motion information for the subject within the region of interest, and applies this information to reduce blurring in the cropped image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a deblurring process is executed on the entire captured image, then blurring in the captured image can be reduced, but blurring in the cropped image portion cannot be necessarily removed
Solution Approach 1:
The patent divides the image processing into two stages: first performing deblurring on the entire captured image, then cropping the desired portion. This segmentation approach ensures that the deblurring algorithm processes all image data including the cropped region, thereby removing blurring effectively in the final cropped image output
2Manufacturing precision
If the entire image is processed for deblurring, then processing time increases, but the cropped image portion still may not have blurring removed
Solution Approach 1:
The patent performs deblurring processing on the entire captured image before cropping. By executing the deblurring algorithm in advance on the complete image data, the system ensures that when the cropped portion is extracted, the blurring has already been removed from that region, achieving effective blurring removal without requiring additional processing time on the cropped image itself

AI summary
This image processing device includes a composition determination unit that determines a composition in an image in accordance with a rule predetermined in a manner that depends on a subject, a region-of-interest determination unit that determines a region of interest in a cropped image corresponding to the composition in the image, and a motion information calculation unit that calculates motion information regarding motion of the subject predetermined in the region of interest.
